Background technique
[0002]
Currently, an NR (New Radio, New Radio) system supports at most one Semi-persistent Scheduling (SPS, Semi-persistent Scheduling) configuration on one BWP (Bandwidth Part, bandwidth part) in a serving cell (serving cell). Moreover, according to the requirements of the existing business model, the period of the SPS is relatively long, and the minimum period is 10ms. However, with the introduction of new service models, the NR system needs to be able to activate multiple semi-persistent scheduling configurations simultaneously on one BWP of one serving cell. In addition, the minimum transmission period of the SPS also needs to be greatly shortened. Therefore, when multiple SPS configurations on one BWP of a serving cell are activated simultaneously, their corresponding HARQ-ACK (Hybrid Automatic Repeat request-Acknowledgement, Hybrid Automatic Repeat request-Acknowledgement) information may be sent in the same time unit. However, the prior art cannot solve this problem.

SUMMARY OF THE INVENTION
[0005]
The inventor found that when at least two SPSs are configured and activated on the same BWP of the same serving cell at the same time, their corresponding HARQ-ACK information may be sent in the same time unit. However, existing mechanisms cannot handle this situation. If there is no corresponding solution, the period corresponding to the SPS configuration, the time domain location, etc. will be limited; and, since the HARQ-ACK information corresponding to multiple activated SPS configurations cannot be sent at the same time, some SPS configurations may be made. The corresponding HARQ-ACK information is delayed to be sent, thereby increasing the delay of the corresponding HARQ-ACK feedback, thereby affecting the system performance.

[0052]
Currently, in the NR system, a data signal reception feedback mechanism is introduced into the physical layer downlink data transmission. Specifically, the UE will receive the PDSCH at the designated time-frequency position according to the instruction (PDCCH, physical downlink control channel) of the base station, and at the same time, the UE needs to make corresponding HARQ feedback on the reception of the PDSCH. When the UE successfully decodes the PDSCH at the time-frequency position, the UE needs to feed back an ACK to the base station; when the UE fails to decode the PDSCH at the time-frequency position, the UE needs to feed back a NACK to the base station. By receiving the HARQ feedback from the UE, the base station can determine which downlink data needs to be retransmitted accordingly, and can also determine the quality of the downlink channel according to the ratio of ACK and NACK in the HARQ feedback, so as to adjust the modulation and coding method of downlink transmission accordingly.
[0053]
In addition, in the NR system, the scheduling of downlink data is mainly divided into two modes: dynamic scheduling (dynamic scheduling) and semi-persistent scheduling (Semi-persistent Scheduling, SPS). For dynamic scheduling, one PDCCH schedules one corresponding PDSCH. On the other hand, semi-persistent scheduling means that a PDCCH can activate a series of PDSCH transmissions, wherein a series of PDSCHs are repeatedly transmitted with P as a period. When the UE receives the activation signaling of semi-persistent scheduling, the UE obtains the time-frequency position of the first PDSCH according to the indication in the PDCCH and the pre-configured indication. The PDSCH is periodically received or monitored in the time domain. When the UE receives the semi-persistent scheduling deactivation signaling, the UE stops receiving or monitoring the corresponding PDSCH.
[0054]
Whether it is dynamic scheduling or semi-persistent scheduling, corresponding to each PDSCH, the UE generally feeds back ACK or NACK information, that is, performs HARQ feedback.
[0055]
For dynamic scheduling, the downlink control information (DCI) indicating the corresponding PDSCH includes the PDSCH-to-HARQ_feedback timing indicator field, which is used to indicate the PDSCH and the PUCCH carrying the corresponding HARQ-ACK information bit (referred to as HARQ bit) The offset k between resources, as shown in Figure 1. That is, when PDSCH is in slot n, its corresponding ACK or NACK feedback is sent in slot n+k. In addition, the DCI also includes a PUCCH resource indicator field, which is used to indicate the PUCCH resource carrying the corresponding HARQ-ACK information bits.
[0056]
For semi-persistent scheduling, the DCI used to activate SPS includes the PDSCH-to-HARQ_feedback timing indicator field, which is used to indicate the offset between each PDSCH and the PUCCH resource that carries the corresponding HARQ-ACK information bits k, as shown in Figure 2. In addition, in addition to the PDSCH directly indicated by the activated DCI, if there is only HARQ feedback corresponding to PDSCH (without corresponding PDCCH) in the corresponding time slot, the UE determines the corresponding HARQ according to IE n1PUCCH-AN in the SPS configuration. - PUCCH resource for ACK information bits.
[0057]
When more than one PDSCH ACK/NACK feedback (that is, HARQ-ACK information) is instructed to be sent in the same time slot, in order to avoid power loss, the ACK/NACK information bits corresponding to semi-persistent scheduling and the ACK corresponding to dynamic scheduling /NACK information bits need to be multiplexed in the same uplink resource. As shown in Fig. 3, when the ACK/NACK feedback of dynamic scheduling and semi-persistent scheduling are instructed to be sent in the same time slot, their corresponding ACK/NACK feedback contents will be put together, and the dynamic scheduling (DCI#2 ) to perform feedback on the uplink resources indicated by .
[0058]
In addition, when the HARQ-ACK information corresponding to different PDSCHs is sent in the same time slot, the UE will determine the sequence of the corresponding HARQ-ACK information bits according to a predefined rule, thereby generating the corresponding HARQ-ACK codebook. After the codebook is generated, the UE will send an uplink signal (PUCCH/PUSCH) for carrying the codebook.
[0059]
In the description of the embodiments of this application, the HARQ-ACK information, that is, the HARQ feedback information, may include both ACK information bits and NACK information bits.

[0061]
The following describes the scenarios of the embodiments of the present application by using examples, but the embodiments of the present application are not limited thereto.
[0062]
FIG. 4 is a schematic diagram of an application scenario of an embodiment of the present application. As shown in FIG. 4 , in the embodiment of the present application, for convenience of description, the concept of a first set is defined, and the first set at least includes {SPS PDSCH#1, SPS PDSCH#2,...,SPS PDSCH#M}, wherein one element represents one SPS PDSCH reception, denoted as SPS PDSCH#m, m=1, 2, 3,..., M, (M>=2). In addition, in this embodiment of the present application, SPS PDSCH#1, SPS PDSCH#2, . . . , SPS PDSCH#M correspond to the same BWP or CC or serving cell or the same BWP of the same serving cell.
[0063]
In the embodiment of the present application, an implementation is that the terminal device is configured to receive the SPS PDSCH#m in the time slot nK m , and the SPS PDSCH#m is activated, that is, the SPS configuration corresponding to the SPS PDSCH#m In the time slot nK m is active. Among them, n refers to the time slot corresponding to SPS PDSCH #m for sending feedback information; K m refers to the time domain offset between the PDSCH of SPS PDSCH #m and the corresponding HARQ feedback (PDSCH-to-HARQ-ACK -feedback timing value), that is, the time slot interval between the time slot in which the SPS PDSCH #m is received and the time slot in which the corresponding HARQ-ACK information is located. It should be noted that the transmission time of the HARQ-ACK information corresponding to the reception of all SPS PDSCHs in the first set is in the same time slot (that is, the time slot n).
[0064]
In the embodiment of this application, another implementation is that the terminal device is configured to receive the SPS PDSCH#m in the time slot n m , and the SPS PDSCH#m is activated, that is, the SPS corresponding to the SPS PDSCH#m The configuration is active at slot n m . Here, the (uplink) sub-slots corresponding to SPS PDSCH #m are n'-K' m , that is, the PDSCH end symbols corresponding to SPS PDSCH #m are in sub-slots n'-K' m . Among them, n' refers to the sub-slot corresponding to SPS PDSCH#m for sending feedback information, that is, the starting symbol of the uplink signal corresponding to the feedback information is in sub-slot n'; K' m refers to the SPS PDSCH The sub-slot interval between the sub-slot corresponding to the end symbol of PDSCH corresponding to #m and the sub-slot corresponding to the end symbol of HARQ feedback corresponding to SPS PDSCH #m (PDSCH-to-HARQ-ACK-feedback timing value). It should be noted that the transmission times of the HARQ-ACK information corresponding to all SPS PDSCH receptions in the first set are in the same sub-slot (ie, sub-slot n').
[0065]
The above description only takes time slots and subslots as examples, and the time unit in the above description may also be subframes, symbols or frames.
[0066]
Various embodiments of the present application will be described below with reference to the accompanying drawings. These embodiments are exemplary only, not limiting of the present application.
[0067]
Embodiments of the first aspect
[0068]
An embodiment of the first aspect of the present application provides a signal sending method, and the method is applied to a terminal device. FIG. 5 is a schematic diagram of a signal sending method according to an embodiment of the first aspect of the present application. Please refer to FIG. 5 . The method includes:
[0069]
Operation 501: The terminal device generates a first feedback signal according to at least a first set, the first set includes at least two SPS PDSCH receptions, and the SPS PDSCH receptions of the first set correspond to the same bandwidth part (BWP) or carrier element (Component Carrier) or serving cell or the same BWP of the same serving cell;
[0070]
Operation 502: The terminal device sends the first feedback signal.
[0071]
According to the embodiment of the present application, on the same BWP or CC or serving cell or the same BWP of the same serving cell (that is, the same BWP of a serving cell), the HARQ ACK information corresponding to the reception of at least two SPS PDSCHs can be received on the same BWP. Feedback within one time unit, thus, the network device can more flexibly configure multiple SPSs in the same BWP or CC or serving cell or the same BWP of the same serving cell, and can also reduce the delay of SPS feedback information.
[0072]
In the embodiment of the present application, SPS PDSCH reception refers to that the terminal device monitors or receives the corresponding PDSCH according to the SPS-activated DCI and the corresponding SPS configuration information. When the terminal device successfully decodes the SPS PDSCH at the corresponding time-frequency position, it feeds back ACK, and if the SPS PDSCH is not successfully decoded at the corresponding time-frequency position, it feeds back NACK. Here, the SPS-activated DCI (that is, the DCI used to activate the SPS) refers to, with regard to the corresponding SPS configuration, the latest SPS-activated DCI in the time domain, that is, there is no other (belonging to the SPS-activated DCI) between the SPS-activated DCI and its corresponding SPS PDSCH. The same SPS configuration) SPS activates DCI. In addition, the SPS-activated DCI may be, for example, a DCI format scrambled by CS-RNTI. Among them, for example, the new data indicator field (new data indicator field) for enabling the transport block in the SPS activation DCI is "0", that is, "a new data indicator field for the enabled transport block is set to'0'" .
[0073]
Taking Figure 2 as an example, the SPS activated DCI is the leftmost DCI, and SPS PDSCH reception means that the UE monitors/receives the corresponding PDSCH in slot n or receives/monitors the corresponding PDSCH in slot n+P, or subsequently uses P as the Periodic slots monitor/receive the corresponding PDSCH (eg, slot n+2P). Taking Figure 3 as an example, the SPS activation DCI is DCI#1, and the SPS PDSCH reception means that the UE monitors/receives the corresponding PDSCH in slot n or receives/monitors the corresponding PDSCH in slot n+P, or subsequently takes P as the period. The slot monitors/receives the corresponding PDSCH (eg, slot n+2P). In the example of FIG. 3 , DCI#2 is dynamic DCI instead of the aforementioned SPS-activated DCI, and the PDSCH scheduled by DCI#2 is not the PDSCH corresponding to the aforementioned SPS PDSCH reception.
[0074]
In at least one of the embodiments of the present application, the SPS PDSCH receptions in the first set correspond to the same HARQ-ACK codebook, so that system resources can be better utilized and transmission reliability can be ensured at the same time . For example, the HARQ-ACK feedback of SPS PDSCH#1, SPS PDSCH#2, ..., SPS PDSCH#M corresponds to the same HARQ-ACK codebook, and the HARQ-ACK codebook may be slot-based or slot-based Sub-slot based, the present application is not limited thereto.
[0075]
In one embodiment, the HARQ-ACK codebook identifiers of the SPS configurations corresponding to the SPS PDSCH receptions (SPS PDSCH#1, SPS PDSCH#2, ..., SPS PDSCH#M) in the first set are the same.
[0076]
For example, in the first set, the RRC IEs related to semi-persistent scheduling corresponding to all SPS PDSCH receptions include 'codebook=slot-based', that is, all PDSCH HARQ feedbacks belong to slot-based HARQ- ACK codebook. Here, slot-based means that the time domain position of the uplink resource corresponding to the HARQ-ACK information is determined by the time domain indication in the unit of slot.
[0077]
For another example, in the first set, the RRC IEs related to semi-persistent scheduling corresponding to all SPS PDSCH receptions include 'codebook=sub-slot based', that is, all PDSCH HARQ feedbacks belong to sub-slot based HARQ-ACK codebook. Here, sub-slot based means that the time domain position of the uplink resource corresponding to the HARQ-ACK information is determined by the time domain indication in the unit of sub-slot.
[0078]
For another example, in the first set, the RRC IEs related to semi-persistent scheduling corresponding to all SPS PDSCH receptions include 'codebook=1', that is, the HARQ-ACK information of all PDSCHs corresponds to the first HARQ -ACK codebook.
[0079]
For another example, in the first set, the RRC IEs related to semi-persistent scheduling corresponding to all SPS PDSCH receptions include 'codebook=2', that is, the HARQ-ACK information of all PDSCHs corresponds to the second HARQ -ACK codebook.
[0080]
The above is only an example, and the present application is not limited to this, and other similar examples can also be derived from the above examples, and the description is omitted here.
[0081]
In another embodiment, the HARQ-ACK codebook identifier (identifier) ​​in the SPS activation DCI corresponding to the SPS PDSCH reception (SPS PDSCH#1, SPS PDSCH#2, ..., SPS PDSCH#M) in the first set same. Here, the SPS activation DCI corresponding to the SPS PDSCH reception means that the SPS PDSCH reception and the SPS activation DCI correspond to the same SPS configuration.
[0082]
For example, the SPS activation DCI contains a field, the size of which is 1 bit, when the codepoint (codepoint) is '0', it represents the slot-based HARQ-ACK codebook, and when the codepoint is '1', it represents the sub- slot-based HARQ-ACK codebook. Here, the value of this field in the SPS active DCI corresponding to SPS PDSCH#1, SPS PDSCH#2, ..., SPS PDSCH#M is the same ('0'/'1').
[0083]
For another example, the SPS activation DCI contains a field, and the size of the field is 2 bits. When the codepoint is '00', it represents HARQ-ACK codebook 1, and when the codepoint is '01', it represents HARQ-ACK codebook 2. When the codepoint is '10', it represents HARQ-ACK codebook 3, and when the codepoint is '11', it represents HARQ-ACK codebook 4. Here, the value of this field in the SPS active DCI corresponding to SPS PDSCH#1, SPS PDSCH#2, ..., SPS PDSCH#M is the same.
[0084]
In at least one of the embodiments of the present application, the first feedback signal includes feedback information corresponding to the reception of the SPS PDSCH in the first set, and the feedback information corresponding to the reception of the SPS PDSCH in the first set is in The order in the first feedback signal is related to (or determined by) at least one of the following ways:
[0085]
The sequence of the starting time domain position or ending time domain position of the PDSCH corresponding to the SPS PDSCH reception in the first set;
[0086]
ascending or descending order of SPS configuration IDs corresponding to SPS PDSCH receptions in the first set; and
[0087]
The sequence of the starting time domain position or the ending time domain position of the SPS-activated DCI corresponding to the SPS PDSCH reception in the first set.
[0088]
Therefore, the terminal device and the network device can determine the meaning of the HARQ-ACK information according to the sequence of bits (bits) of the HARQ-ACK information. That is, it can be determined whether the corresponding SPS PDSCH in the first set is successfully received.
[0089]
In addition, when the above order is related to the sequence of the starting time domain position or ending time domain position of the PDSCH corresponding to the SPS PDSCH reception in the first set, not only can the starting/ending position of the PDSCH be used to distinguish the corresponding HARQ -The order of the ACK information bits (bits) can also enable the SPS PDSCH reception with the earlier PDSCH time domain position to be preferentially processed to generate HARQ-ACK information bits earlier, in line with the hardware processing timing, speeding up the processing process, thereby saving System resource overhead.
[0090]
In addition, when the above order is related to the ascending or descending order of the SPS configuration IDs corresponding to the SPS PDSCH reception in the first set, not only can the SPS configuration IDs corresponding to the PDSCH be able to distinguish the order of the corresponding HARQ-ACK information bits, but also the order of the corresponding HARQ-ACK information bits can be made. The PDSCHs corresponding to different SPS configuration IDs have different priority levels, that is, when the UE cannot transmit all the HARQ-ACK bits corresponding to the first set of SPS PDSCH receptions, a part of the bits can be removed according to the order, so that the feedback information is more efficient. The number of bits matches the corresponding transmission resource.
[0091]
In addition, when the above order is related to the sequence of the starting time domain position or the ending time domain position of the SPS activation DCI corresponding to the SPS PDSCH reception in the first set, not only can the SPS activation DCI corresponding to the PDSCH be able to distinguish the corresponding HARQ- The order of the ACK information bits can also make the PDSCHs corresponding to different SPS activated DCIs have different priority levels, that is, when the UE cannot transmit all the HARQ-ACK information bits corresponding to the first set of SPS PDSCH reception, it can be based on the order. Part of the bits are sequentially removed, so that the number of bits of the feedback information matches the corresponding transmission resources.
[0092]
Similar to the aforementioned time unit, the aforementioned time domain position may be one of a frame, a subframe, a slot, a sub-slot, and a symbol. limited to this.
[0093]
For example, it is assumed that the feedback information bits corresponding to SPS PDSCH#1, SPS PDSCH#2,..., SPS PDSCH#M are O 1 , O 2 ,..., O M , respectively . In the first feedback signal, it is assumed that the order of the feedback information bits is {O 1 , O 2 , . . . , O M } (from O 1 to O M ), then the order is determined by one of the following methods:
[0094]
Method 1, the start or end position of the PDSCH signal, that is, the above sequence is determined by the start/end position of the PDSCH signal corresponding to SPS PDSCH#m, for example, the start symbol of the PDSCH signal corresponding to SPS PDSCH#m is StartPDSCH# m, then:
[0095]
Arrangement according to the time domain ascending order of the starting position of the corresponding PDSCH signal means: StartPDSCH#1>=StartPDSCH#2>=...>=StartPDSCH#M;
[0096]
Arrangement according to the time domain descending order of the starting positions of the corresponding PDSCH signals means: StartPDSCH#1<=StartPDSCH#2<=...<=StartPDSCH#M.
[0097]
Method 2, SPS configuration ID, that is, the above order is determined by the size of the SPS configuration ID (SPS config#m) corresponding to the SPS PDSCH#m, for example,
[0098]
In ascending order of the corresponding SPS configuration ID: SPS config#1>=SPS config#2>=…>=SPS config#M;
[0099]
In descending order of corresponding SPS configuration IDs: SPS config#1<=SPS config#2<=...<=SPS config#M.
[0100]
Method 3, the start or end position of the SPS activation DCI, that is, the above sequence is determined by the start/end position of the SPS activation DCI corresponding to the SPS PDSCH#m, for example, the start of the SPS activation DCI corresponding to the SPS PDSCH#m. The start symbol is StartPDCCH#m, then:
[0101]
Arrangement according to the time domain ascending order of the starting position of the corresponding PUCCH signal means: StartPDCCH#1>=StartPDCCH#2>=...>=StartPDCCH#M;
[0102]
Arrangement according to the time domain descending order of the starting positions of the corresponding PUCCH signals means: StartPDCCH#1<=StartPDCCH#2<=...<=StartPDCCH#M.
[0103]
Here, the SPS-activated DCI corresponding to the SPS PDSCH#m refers to the SPS-activated DCI with the closest time domain distance to the SPS PDSCH#m and corresponding to the same SPS configuration.
[0104]
The above three methods can be used separately or in combination. For example, first compare the starting positions of the PDSCH, if they are the same, then further compare the size of the SPS configuration ID, and vice versa; for example, first compare the size of the SPS configuration ID, Then compare where SPS activates DCI, etc., and vice versa.
[0105]
In the foregoing operation 501 of the embodiment of the present application, in at least one embodiment, the terminal device may generate the foregoing first feedback signal according to the first set and the maximum number of HARQ-ACK information bits. Here, the maximum number of HARQ-ACK information bits refers to: the maximum number of HARQ-ACK information bits related to the SPS in an uplink signal (for example, PUCCH).
[0106]
In an embodiment, the maximum number of HARQ-ACK information bits may be indicated by RRC (Radio Resource Control) signaling, that is, configured by the network device through RRC signaling.
[0107]
For example, the network device sends an RRC signaling to the terminal device, which indicates that the terminal device is allowed to send at most N max SPS-related HARQ feedback bits in one uplink resource/signal in one uplink resource, then, Nmax is the above-mentioned maximum HARQ - the number of ACK information bits, and,
[0108]
When the total number of HARQ-ACK bits corresponding to all SPS PDSCH receptions in the first set is less than or equal to N max , the first feedback signal includes all SPS HARQ feedback bits corresponding to SPS PDSCH receptions in the first set;
[0109]
When the total number of HARQ-ACK bits corresponding to all SPS PDSCH receptions in the first set is greater than N max , the first feedback signal includes at most N max HARQ-ACK bits corresponding to SPS PDSCH receptions in the first set . At this time, only a part of the HARQ-ACK information corresponding to the SPS PDSCH reception in the first set is included in the first feedback signal.
[0110]
In the embodiment of the present application, the terminal device may determine the above-mentioned part of the SPS PDSCH reception according to the sequence of the PDSCH start/end time domain positions corresponding to the SPS PDSCH reception in the first set. For example, the first feedback signal only includes feedback information (HARQ-ACK bits) received by the SPS PDSCH corresponding to the first PDSCH starting position, so that the number of transmitted bits is less than or equal to the above N max .
[0111]
In the embodiment of the present application, the terminal device may also determine the above-mentioned part of the SPS PDSCH receptions according to the ascending/descending order of the SPS configuration IDs corresponding to the SPS PDSCH receptions in the first set. For example, the first feedback signal only includes feedback information (HARQ-ACK bits) received by PDSCH corresponding to a smaller SPS configuration ID, so that the number of transmitted bits is less than or equal to the above N max .
[0112]
In the embodiment of the present application, the terminal device may also determine the above-mentioned part of the SPS PDSCH reception according to the sequence of start/end time domain positions of the SPS activated DCI corresponding to the SPS PDSCH reception in the first set. For example, the first feedback signal only includes feedback information (HARQ-ACK bits) received by the PDSCH corresponding to the earlier SPS-activated DCI, so that the number of transmitted bits is less than or equal to the above N max .
[0113]
The above three methods can be used separately or in combination. For example, first compare the starting positions of the PDSCH, if they are the same, then further compare the size of the SPS configuration ID, and vice versa; for another example, first compare the size of the SPS configuration ID, Then compare where SPS activates DCI, etc., and vice versa. The present application is not limited to this.
[0114]
In another embodiment, the above-mentioned maximum number of HARQ-ACK information bits may also be related to the capacity (capacity) of the first feedback signal. That is, at most N max SPS-related HARQ feedback bits are allowed to be sent, which are not indicated by RRC signaling but are related to, eg, equal to, the capacity of the first feedback signal. The capacity is related to the time-frequency domain resources, modulation scheme (MCS) and/or code rate of the above-mentioned first feedback signal, which will not be repeated in this application. Therefore, additional indication signaling can be avoided to indicate the maximum number of HARQ-ACK information bits, thereby reducing the resource overhead of the system.
[0115]
In the foregoing operation 501 of this embodiment of the present application, in at least one embodiment, the terminal device may generate the foregoing first feedback signal according to the first set and the maximum number of ACKs related to HARQ-ACK information. Here, the HARQ-ACK information refers to HARQ-ACK information related to the SPS.
[0116]
In one embodiment, the maximum number of ACKs related to HARQ-ACK information refers to the maximum number of ACKs related to HARQ-ACK information in an uplink signal (for example, PUCCH), which may be determined by RRC Indicated by signaling, that is, configured by the network device through RRC signaling.
[0117]
For example, the network device sends RRC signaling to the terminal device, which indicates that the terminal device is allowed to send at most P SPS-related 'ACKs' in one uplink resource, that is, it indicates that the terminal device has at most P valid SPS PDSCHs corresponding to reception The HARQ information may be ACK, and the HARQ information corresponding to other SPS PDSCH receptions in the first set is NACK. Therefore, the number of ACKs that may be included in the feedback information is 0, 1, 2, ..., P. Assuming that the number of SPS-related HARQ feedback bits corresponding to the first feedback signal is N, feedback may occur Therefore , the terminal equipment does not need to generate N-bit HARQ-ACK information in the first feedback signal, but generates a certain number of bits corresponding to all the above possible states, that is, in the first feedback signal The number of generated bits is: In this way, the RRC signaling can flexibly configure the number of ACKs, thereby enabling more SPS PDSCHs to feed back HARQ-ACK information within the same time unit. In addition, limiting the number of ACKs can greatly reduce possible combinations of feedback information, thereby saving the information bit overhead required for HARQ feedback.
[0118]
In another embodiment, the above-mentioned maximum number of ACKs related to HARQ-ACK information is predefined. That is, at most P SPS-related ACKs are allowed to be sent that are not indicated by RRC but are predefined, eg, 2. In this way, additional indication signaling (to indicate the number of ACKs) can be avoided, and signaling overhead can be saved.
[0119]
According to the above method of the embodiment of the present application, in the HARQ-ACK information, the position of the HARQ-ACK information bit corresponding to each SPS PDSCH can be determined, so that the network device and the terminal device can be based on the sequence of the HARQ-ACK information bits. Determine the meaning of the feedback information.
[0120]
In the embodiments of the present application, in at least one embodiment, the above-mentioned first feedback signal only includes HARQ-ACK information corresponding to PDSCH reception (PDSCH without corresponding PDCCH), but does not include PDSCH reception corresponding to PDCCH (PDSCH without corresponding PDCCH). PDSCH with corresponding PDCCH) corresponding HARQ-ACK information. Here, the PDSCH without corresponding PDCCH means that the PDSCH is directly scheduled without the PDCCH, for example, the PDSCH in the SPS except the initial (initial) PDSCH indicated by the SPS-activated DCI. Here, the initial PDSCH refers to the first corresponding PDSCH after the SPS activates the DCI. Therefore, since there is no directly corresponding PDCCH, the resource indication of the first feedback signal cannot be directly provided by the PDCCH, so the resource may be the uplink resource corresponding to the reception of an SPS PDSCH in the first set, or may be the first The uplink resources in the second set, the uplink resources in the second set may be related to the size of the HARQ-ACK information corresponding to the SPS PDSCH reception in the first set, and the specific method will be described below.
[0121]
In this embodiment of the present application, in at least one embodiment of operation 502, the terminal device may use the first uplink resource to send the above-mentioned first feedback signal, and the first uplink resource may be a SPS PDSCH in the above-mentioned first set received by one SPS PDSCH. The corresponding configured uplink resources.
[0122]
For example, the SPS PDSCH reception corresponding to the first uplink resource may be an SPS PDSCH reception with the largest or smallest SPS configuration ID corresponding to the SPS PDSCH reception in the first set. Assuming that the configured PUCCH resource for HARQ-ACK feedback corresponding to SPS PDSCH #m in the first set is PUCCH m , and the SPS configuration ID corresponding to SPS PDSCH #m is SPS m , the terminal device can PUCCH i sends the first feedback signal, wherein or
[0123]
For another example, the SPS PDSCH reception corresponding to the first uplink resource may be the earliest or latest SPS PDSCH reception at the PDSCH start time domain position or end time domain position corresponding to the SPS PDSCH reception in the first set. Assume that the configured PUCCH resource corresponding to SPS PDSCH #m in the first set for HARQ-ACK feedback is PUCCH m . In addition, the PDSCH starting time domain position (symbol/slot/sub-slot) corresponding to SPS PDSCH #m is then the terminal device can send the first feedback signal according to PUCCH i , where or
[0124]
For another example, the reception of the SPS PDSCH corresponding to the first uplink resource may be the earliest or latest SPS PDSCH in the HARQ PUCCH resource configuration corresponding to the reception of the SPS PDSCH in the first set. take over. Assume that the configured PUCCH resource for HARQ-ACK feedback corresponding to SPS PDSCH #m in the first set is PUCCH m (for example, it is indicated by IE: n1 PUCCH-AN in the indication of HARQ PUCCH resource in the corresponding SPS configuration SPS-config PUCCH resource). In addition, the starting time domain position (symbol/slot/subslot) of PUCCH m is then the terminal device can send the first feedback signal according to PUCCH i , where or
[0125]
For another example, the SPS PDSCH reception corresponding to the first uplink resource may be an SPS PDSCH reception in which the PUCCH corresponding to the SPS PDSCH reception in the first set satisfies a predefined timeline (timeline). Assume that the configured PUCCH resource corresponding to SPS PDSCH #m in the first set for HARQ-ACK feedback is PUCCH m . In addition, the end time domain position (symbol/slot/subslot) of the PDSCH corresponding to SPS PDSCH #m is In addition , the PUCCH starting time domain position corresponding to SPS PDSCH #m for carrying the corresponding HARQ-ACK information (symbol/slot/sub-slot) is when the terminal device can send the first feedback signal according to PUCCH i . Among them, T is a predefined threshold, for example, the same as N 2 timeline, that is, it is equivalent to the minimum time interval between PDSCH transmission and corresponding HARQ-ACK feedback. ) sub-carrier spacing (SCS, Sub-carrier Spacing) correlation.
[0126]
For another example, the SPS PDSCH reception corresponding to the first uplink resource may be an SPS PDSCH reception whose PUCCH capacity (capacity) corresponding to the SPS PDSCH reception in the first set is greater than or equal to the corresponding total payload size (payload size). Assume that the configured PUCCH resource corresponding to SPS PDSCH #m in the first set for HARQ-ACK feedback is PUCCH m . In addition, the number of HARQ information bits corresponding to SPS PDSCH #m is N m . In addition, the capacity of the PUCCH corresponding to the SPS PDSCH #m and used to carry the corresponding HARQ-ACK information is C m , when the terminal device can send the first feedback signal according to PUCCH i .
[0127]
In this example, if the capacity of no PUCCH is greater than or equal to the total load size, the terminal device may send the first feedback signal according to the PUCCH resource with the largest capacity. That is, the SPS PDSCH reception corresponding to the first uplink resource may be an SPS PDSCH reception with the largest PUCCH capacity (capacity) corresponding to the SPS PDSCH reception in the first set. That is, if the SPS PDSCH in the first set does not have a corresponding PUCCH m that satisfies the above conditions , the terminal device can send the first feedback signal according to PUCCH i' , where
[0128]
In the embodiment of the present application, the capacity of the above-mentioned PUCCH is related to the time-frequency domain resource size, modulation mode, and/or code rate of the PUCCH resource, and the present application is not limited thereto.
[0129]

The resource is related to the size of the HARQ-ACK information corresponding to the SPS PDSCH reception in the first set.
[0130]
Taking the second uplink resource as the PUCCH resource as an example, the second set may include {PUCCH#1, PUCCH#2, ..., PUCCH#K}, where one element is denoted as PUCCH#k, k=1, 2, 3 , ..., K, (K>=1). And, for example, the uplink resources in the second set may be arranged in ascending or descending order of resource capacity.
[0131]
For example, it is assumed that the number of HARQ feedback bits corresponding to SPS PDSCH #m in the first set is N m . In addition, the PUCCH resource capacity corresponding to PUCCH #k is C k , when the terminal device can send the first feedback signal according to PUCCH i . If there is no PUCCH resource that meets the above conditions in the second set, the terminal device may send a first feedback signal according to PUCCH k' , where,
[0132]
For another example, it is assumed that the ranges of payload sizes corresponding to the second set {PUCCH#1, PUCCH#2, ..., PUCCH#K} are PUCCH#1→{P0, P1}, PUCCH#2→{P 1 , P 2 , respectively }, ..., PUCCH#K→{P K-1 , P K }. When , the terminal device may send the first feedback signal according to PUCCH k' . If there is no PUCCH k' that satisfies the above conditions , the terminal device sends a first feedback signal according to PUCCH k'', wherein ,
[0133]
In this embodiment of the present application, the above-mentioned second uplink resource may be indicated by RRC signaling, that is, the terminal device may use the above-mentioned second uplink resource to send the first feedback signal according to the RRC signaling. The RRC signaling is to instruct the terminal device to use the uplink resources in the second set to transmit the HARQ-ACK information corresponding to the SPS PDSCH reception in the first set. For example, the IE name of this RRC signaling is 'SPS-HARQ-multiplexing-PUCCH', which can be configured to be enabled (enable) or disabled (disabled) or not configured (eg, not configured is equivalent to disable Enable). Under the condition that the RRC is enabled, the terminal device can transmit the HARQ information corresponding to the reception of the SPS PDSCH in the first set according to the uplink resources in the second set; if the RRC signaling indicates that it is disabled, Then the terminal device needs to send the first feedback signal according to the HARQ PUCCH resource corresponding to the SPS PDSCH reception, and the specific implementation method is as described above.
[0134]
In this embodiment of the present application, in at least one embodiment of operation 502, the terminal device may send the first feedback signal according to RRC signaling. For example, the enabled state of the RRC signaling indicates that the terminal device allows the feedback information corresponding to at least two SPS PDSCHs on the same BWP to be multiplexed in the same uplink resource. For example, the IE name of this RRC signaling is 'SPS-HARQ-multiplexing', which can be configured to be enabled or disabled or not configured (eg, not configured is equivalent to disabled). That is, when the RRC signaling indicates the corresponding enable state, the terminal device can send the first feedback signal; if it is disabled (or not configured), the terminal device cannot send the first feedback signal.
[0135]
In this embodiment of the present application, in at least one embodiment of operation 502, the terminal device may send the first feedback signal according to the reported (reported) terminal device capability (UE capability). This capability means that the terminal device can multiplex feedback information corresponding to at least two SPS PDSCHs on the same BWP in the same uplink resource. The capability may be related to all CCs/serving cells of the terminal device, or the capability may be reported separately by each CC/serving cell, and the present application is not limited thereto. When the terminal device has the capability and reports the corresponding information to the network device, the terminal device can send the first feedback signal according to the method described herein.
[0136]
According to the above method of the embodiment of the present application, the uplink resource (uplink signal) used to carry the above feedback information is selected, so that the feedback information can be transmitted on an uplink signal with a suitable time and frequency size, which ensures the reliability of transmission and improves the system. performance.
[0137]
Through the method of the embodiment of the present application, the network device can configure multiple SPSs (more flexible period, starting position) in the same BWP/CC/serving cell/the same BWP of the same serving cell more flexibly, and can also reduce the The delay for SPS to transmit feedback information.
