SUMMARY OF THE INVENTION
[0005]
The inventor found that, at present, there is no corresponding mechanism for determining the priority or HARQ-ACK codebook corresponding to the HARQ-ACK information corresponding to the joint SPS PDSCH release. The joint SPS PDSCH release refers to an SPS PDSCH release corresponding to a specific state; wherein the specific state is associated with one or more than one SPS configuration. This will cause the terminal device to be unable to determine the priority of the HARQ-ACK information, so that the UE cannot handle the collision of the HARQ-ACK signal with other signals, that is, cannot perform prioritization or multiplexing processing with other signals (prioritization/multiplexing handling) .

Embodiments of the first aspect
[0070]
An embodiment of the first aspect of the present application provides a wireless communication method, and the method is applied to a terminal device. FIG. 3 is a schematic diagram of a wireless communication method according to an embodiment of the present application. Referring to FIG. 3, the method includes:
[0071]
Operation 301: The terminal device receives first configuration information, the first configuration information indicates that one or more SPS configurations are associated with one SPS configuration set, the one or more SPS configurations correspond to the same priority or the same The HARQ-ACK codebook.
[0072]
According to the method of this embodiment of the present application, all SPS configurations associated or mapped in an SPS configuration set correspond to the same priority or HARQ-ACK codebook. In this way, the same priority or HARQ-ACK codebook can be regarded as the priority or HARQ-ACK codebook corresponding to the HARQ-ACK information corresponding to the control information (joint SPS PDSCH release). Through this restriction on the first configuration information, the priority or HARQ-ACK codebook indication corresponding to the HARQ-ACK information can be implemented concisely, without additional rules. In addition, the method can further help the terminal device to determine the time domain position for sending the HARQ-ACK information, thereby improving the reliability of the system.
[0073]
In the embodiment of this application, "the first configuration information indicates that one SPS configuration set is associated with one or more SPS configurations" means that the terminal device receives the first configuration information sent by the network device, such as RRC configuration information, The first configuration information is used to indicate that a state (eg, SPS-ConfigDeactivationState) in a list (eg, SPS-ConfigDeactivationStateList) is mapped or associated with one or more SPS configurations. The number of possible mappings or associated SPS configurations for each state is 1, 2, 3, ..., 8. In addition, the list may contain 1,2,3,...,16 states; or, the list may contain 1,2,3,...,2 N_HPN . Wherein, N_HPN refers to the length of the HPN field in DCI format 1_2, and the length may be indicated by RRC signaling (eg, HARQProcessNumberSize-ForDCIFormat1_2), but the present application is not limited thereto.
[0074]
In this embodiment of the present application, the first configuration information may act on a bandwidth unit (BWP), that is, the first configuration information may indicate configuration information on a specific BWP (bandwidth unit), but the present application is not limited to this .
[0075]
In the embodiments of the present application, unless otherwise specified, "state" and "SPS configuration set" are equivalent. illustrate.
[0076]
In this embodiment of the present application, one or more than one SPS configuration corresponds to the same priority. It can also be understood that the terminal device expects one or more SPS configurations to correspond to the same priority, or the terminal device expects one or more than one SPS configuration to correspond to the same priority. A SPS configuration corresponds to the same priority.
[0077]
For example, as mentioned above, state #1 is associated with SPS configuration #1, SPS configuration #2, and SPS configuration #3, then the priorities corresponding to SPS configuration #1, SPS configuration #2, and SPS configuration #3 are the same of.
[0078]
Here, state #1 refers to the first element/value of a state list (eg SPS-ConfigDeactivationStateList); SPS configuration #1 may refer to an SPS configuration (SPS-Config) whose corresponding index (SPS- ConfigIndex) is 1. By analogy, state #n refers to the nth element/value of a state list (eg SPS-ConfigDeactivationStateList); SPS configuration #n can refer to an SPS configuration (SPS-Config) whose corresponding index ( SPS-ConfigIndex) is n. In the embodiments of the first aspect of the present application and the embodiments of other aspects of the present application, the described "status" and "SPS configuration" are all applicable to the above explanation, and the explanation will not be repeated.
[0079]
In one example, according to RRC signaling, SPS configuration #1 is associated with high priority; at the same time, according to RRC signaling, SPS configuration #2 is also associated with high priority; at the same time, according to RRC signaling , SPS configuration #3 is also associated with high priority. Thus, the three SPS configurations associated with state #1 correspond to the same priority. Here, the value corresponding to the high priority in the RRC signaling is 1. In addition, this RRC signaling is used to indicate whether the SPS configuration is high priority or low priority in PHY prioritization/multiplexing handling. For example, determine the HARQ codebook corresponding to the HARQ-ACK information of the SPS PDSCH or the HARQ-ACK information of the SPS PDSCH release.
[0080]
Here, the SPS configuration #n is associated with a high priority means that an SPS configuration with an index value (SPS-ConfigIndex) of n has a corresponding priority value of high, or 0, or 1.
[0081]
In another example, according to RRC signaling, SPS configuration #1 is associated with low priority; at the same time, according to RRC signaling, SPS configuration #2 is also associated with low priority; at the same time, according to RRC signaling Let, SPS configuration #3 is also associated with low priority. Thus, the three SPS configurations associated with state #1 correspond to the same priority. Here, the value corresponding to the low priority in the RRC signaling is 0. In addition, this RRC signaling is used to indicate whether the SPS configuration is high priority or low priority in PHY prioritization/multiplexing handling. For example, determine the HARQ codebook corresponding to the HARQ-ACK information of the SPS PDSCH or the HARQ-ACK information of the SPS PDSCH release.
[0082]
Here, the SPS configuration #n being associated with the low priority refers to an SPS configuration whose index value (SPS-ConfigIndex) is n, and the corresponding priority value is low, or 1, or 0.
[0083]
Here, the value of the priority signaling corresponding to the high priority may be high, which may be 0 or 1. That is, if the value of priority signaling corresponding to high priority is high, the value of priority signaling corresponding to low priority is low; if the value of priority signaling corresponding to high priority is 0, then the value of priority signaling corresponding to low priority is low. The value of the priority signaling is 1; on the contrary, if the value of the priority signaling corresponding to the high priority is 1, the value of the priority signaling corresponding to the low priority is 0. In the embodiment of the present application, the value of the priority signaling corresponding to the high priority is 1, and the value of the priority signaling corresponding to the low priority is 0 as an example. In the embodiments of the first aspect of the present application and the embodiments of other aspects of the present application, the above explanations may be used for "association of SPS configuration with high priority" and "association of SPS configuration with low priority", which will not be repeated.
[0084]
In this embodiment of the present application, similar to the case of priority, one or more than one SPS configuration corresponds to the same HARQ-ACK codebook. It can also be understood that the terminal device expects one or more than one SPS configuration to correspond to the same HARQ-ACK codebook. ACK codebook, or the terminal device expects the same HARQ-ACK codebook corresponding to one or more SPS configurations.
[0085]
For example, as described above, state #1 is associated with SPS configuration #1, SPS configuration #2, and SPS configuration #3, then the HARQ-ACK codebooks corresponding to SPS configuration #1, SPS configuration #2, and SPS configuration #3 Are the same.
[0086]
In one example, according to RRC signaling, SPS configuration #1 is associated with the first HARQ-ACK codebook; at the same time, according to RRC signaling, SPS configuration #2 is also associated with the first HARQ-ACK codebook; with this Meanwhile, according to RRC signaling, SPS configuration #3 is also associated with the first HARQ-ACK codebook. Thus, the three SPS configurations associated with state #1 correspond to the same HARQ-ACK Codebook.
[0087]
Here, the first HARQ-ACK codebook may refer to a HARQ-ACK codebook with an index of 0; or a HARQ-ACK codebook with an index of 1; or a HARQ-ACK codebook with a high priority; or a priority of Low HARQ-ACK codebook.
[0088]
In addition, the association of the SPS configuration #n with the first HARQ-ACK codebook may also mean that the SPS configuration #n is associated with the first PUCCH configuration (PUCCH-config). The index corresponding to the first HARQ-ACK codebook is the same as the index corresponding to the first PUCCH configuration.
[0089]
In at least one embodiment, as shown in Figure 3, the method may further include:
[0090]
Operation 303: The terminal device receives control information, where the HPN field of the control information indicates the SPS configuration set.
[0091]
In this embodiment of the present application, the above-mentioned control information (that is, downlink control information DCI) is used to release the SPS configuration, which may also be referred to as "SPS PDSCH release". When the terminal device receives an SPS PDSCH release, the terminal device can determine its corresponding SPS configuration set according to the SPS PDSCH release. For example, the terminal device may determine the corresponding SPS configuration set according to the codepoint (codepoint) of the HPN domain.
[0092]
For example, when the length of the HPN field is 4 bits, the HPN field '0000' represents the SPS configuration set #1; in addition, the HPN field '0001' represents the SPS configuration set #2, and so on, the HPN field '1111' represents the SPS configuration set #16.
[0093]
For another example, when the length of the HPN field is 2 bits, for example, when the length of the HPN field of the DCI format is configurable, for example, DCI format 1_2, the length of the HPN field is determined to be 2 bits according to HARQProcessNumberSize-ForDCIFormat1_2, and the HPN field is '00 ' represents SPS configuration set #1; in addition, HPN field '01' represents SPS configuration set #2, and so on, HPN field '11' represents SPS configuration set #4.
[0094]
In the embodiment of the present application, assuming that the length of the HPN domain is M, the total number of corresponding SPS configuration sets is at most 2 M .
[0095]
In this embodiment of the present application, the CRC of the above-mentioned control information may be scrambled by CS-RNTI, and a new indicator (new data indicator) field of the control information may be 0.
[0096]
In an example, all bits corresponding to the modulation and coding scheme (Modulation and coding scheme) field of the control information are 1, and all bits corresponding to the frequency domain resource assignment (Frequency domain resource assignment) field of the control information (bit) is 1, the control information includes a redundancy version (Redundancy version, RV) field, and all bits (bits) corresponding to the RV field are 0.
[0097]
In another example, all bits corresponding to the modulation and coding scheme (Modulation and coding scheme) field of the control information are 1, and all bits corresponding to the frequency domain resource assignment (Frequency domain resource assignment) field of the control information A bit (bit) is 1, and the control information does not include a redundancy version (Redundancy version, RV) field.
[0098]
In the above two examples, the terminal device has completed the verification (Validation of the DCI format is achieved) through the control information.
[0099]
In this embodiment of the present application, if the MCS field, the FDRA field and the RV field of the control signal all satisfy the settings in the first example, it can be said that the DCI format has completed the verification. Alternatively, if the MCS field, the FDRA field and the RV field of the control information all satisfy the settings in the second example, it can be said that the DCI format has completed the verification. In this embodiment of the present application, if the verification is completed, the terminal device considers that the information in the DCI format is valid SPS deactivation information. If the verification fails to be completed, the terminal device discards all the information in the DCI.
[0100]
In the embodiments of the present application, in some embodiments, the terminal device may further receive second configuration information, where the second configuration information is used to instruct the terminal device to generate at least two HARQ-ACKs. In other words, the second configuration information is used to configure at least two HARQ-ACK codebooks that are simultaneously constructed.
[0101]
For example, the second configuration information is a list (pdsch-HARQ-ACK-Codebook-List), which includes configuration information (pdsch-HARQ-ACK-Codebook) of two HARQ-ACK codebooks. The configuration information (pdsch-HARQ-ACK-Codebook) of each HARQ-ACK codebook is used to indicate whether the HARQ-ACK codebook is semi-static or dynamic.
[0102]
Therefore, if the terminal device does not receive the second configuration information, it may not be necessary for the terminal device to distinguish the priorities corresponding to the HARQ-ACK information. After the terminal device receives the second configuration information, the terminal device needs to generate at least two (including two) HARQ-ACK codebooks with different priorities, so in this case, it is necessary for the terminal device to distinguish the HARQ-ACK information The corresponding (different priority) HARQ-ACK codebook. The addition of this receiving condition helps the terminal device to distinguish under what scenarios the one or more SPS configurations correspond to the same priority or the same HARQ-ACK codebook, so as to avoid erroneously determining the corresponding HARQ-ACK information. Priority or HARQ-ACK codebook.
[0103]
In this embodiment of the present application, as shown in FIG. 3 , the method may further include:
[0104]
Operation 305: According to the priority or HARQ-ACK codebook corresponding to the one or more SPS configurations, the terminal device sends, at the corresponding time domain position, a message for carrying the HARQ-ACK information corresponding to the control information. Signal.
[0105]
In this embodiment of the present application, after the SPS configuration set corresponding to the control information (SPS PDSCH release) is determined through operation 303, since the SPS configurations corresponding to the SPS configuration set correspond to the same priority or HARQ-ACK codebook. According to the priority or the indication of the HARQ-ACK codebook, the terminal device can determine the PUCCH configuration associated with the HARQ-ACK information corresponding to the SPS PDSCH release, and then send the HARQ corresponding to the SPS PDSCH release according to the corresponding configuration information. -Signal of ACK information.
[0106]
For example, when the SPS PDSCH release corresponds to a low priority (for example, the signaling value corresponding to RRC is 0, priority=0), its HARQ-ACK information corresponds to a PUCCH configuration with the same priority index (for example, PUCCH configuration #1, which The associated priority index is 0).
[0107]
For example, when the SPS PDSCH release corresponds to a high priority (for example, the signaling value corresponding to RRC is 1, priority=1), its HARQ-ACK information corresponds to a PUCCH configuration with the same priority index (for example, PUCCH configuration #2, which The associated priority index is 1).
[0108]
For another example, when the SPS PDSCH release corresponds to HARQ-ACK codebook #0, its HARQ-ACK information corresponds to PUCCH configuration #1. The priority associated with HARQ-ACK codebook #0 is the same as the priority associated with PUCCH configuration #1 (priority index is 0).
[0109]
For another example, when the SPS PDSCH release corresponds to HARQ-ACK codebook #1, its HARQ-ACK information corresponds to PUCCH configuration #2. The priority associated with HARQ-ACK codebook #1 is the same as the priority associated with PUCCH configuration #2 (priority index is 1).
[0110]
It should be noted here that HARQ-ACK codebook#0 and HARQ-ACK codebook#1 may be configured by RRC signaling (pdsch-HARQ-ACK-Codebook-List). The RRC signaling is used to instruct the terminal device to generate (simultaneously construct) one or two HARQ-ACK codebooks. In addition, the two HARQ-ACK codebooks may correspond to different priorities respectively. In this embodiment and other embodiments of the present application, both HARQ-ACK codebook #0 and HARQ-ACK codebook #1 are applicable to this explanation, and will not be repeated here.
[0111]
In one embodiment, if the above priority or the PUCCH configuration corresponding to the HARQ-ACK codebook does not include or is not configured with an indication of the length of the subslot, the terminal device sends the signal in units of time slots.
[0112]
For example, when SubslotLength-ForPUCCH is not included or configured in the PUCCH configuration, the terminal device sends the corresponding HARQ-ACK information in the unit of slot according to the information indicated by the PDSCH-to-HARQ_feedback timing indicator field in the SPS PDSCH release.
[0113]
For example, the terminal device receives the SPS PDSCH release at slot n, and the terminal device sends the corresponding HARQ- ACK information.
[0114]
In another embodiment, if the above priority or the PUCCH configuration corresponding to the HARQ-ACK codebook includes or is configured with an indication of the length of the sub-slot, the terminal device uses the sub-slot (sub-slot) as the unit to send the said signal. The length of the symbol corresponding to the sub-slot may be at least 2 or 7.
