Technical field
[0001]
The present invention relates to the field of communications, and in particular to an uplink signal transmission method, uplink signal reception method, device, and system.
Background technique
[0002]
In order to promote the progress of the 3rd Generation Partnership Project 5th Generation (3GPP 5G) standard, several meetings related to this standard were held. In the recent RAN1#91 meeting, the beam indication mechanism for the uplink control channel (PUCCH) has been determined. The spatial relationship of PUCCH resources is determined by the parameter PUCCH-Spatial-relation-info configured by Radio Resource Control (RRC) signaling. Among them, PUCCH-Spatial-relation-info is a list that contains one or more entries, each entry can be a single sideband identifier (SSB ID), and channel state information refers to the signal resource indication (CSI-RS Resource Indication, CRI) Or a sounding reference signal resource indication (SRS Resource Indication, SRI), used to indicate the spatial relationship of the PUCCH. If multiple entries are configured in the PUCCH-Spatial-relation-info, a Media Access Control Unit (MAC-CE) signal is required to associate the spatial relationship of the PUCCH with one of the entries, and the terminal device can use the MAC-CE The spatial relationship of the PUCCH associated with the indicated entry sends an uplink signal; if the PUCCH-Spatial-relation-info contains only one entry, the terminal device will directly apply the configuration without activation using the MAC-CE signal.
[0003]
Figures 1a and 1b show the case where the PUCCH-Spatial-relation-info contains multiple entries and one entry, respectively. As shown in FIG. 1a, in the case where PUCCH-Spatial-relation-info contains multiple entries (RS1 to RS4), each entry may have a number, and each entry indicates a spatial relationship, for example, RS1 indicates Tx1 RS2 indicates Tx2, RS3 indicates Tx3, and RS4 indicates Tx4, where RS1 to RS4 may be SSB ID, CRI, or SRI. Under this configuration, the network device activates or indicates one of the entries through the MAC-CE, for example, activates or indicates RS2, and thus, the terminal device can apply the spatial relationship Tx2 indicated by the RS2 to send an uplink signal. As shown in FIG. 1b, in the case where PUCCH-Spatial-relation-info contains an entry (RS1), the network device does not need to perform other configuration, and the terminal device can directly apply the spatial relationship Tx3 indicated by the entry RS1 to send the uplink signal.
[0004]
It should be noted that the above introduction to the technical background is set forth only to facilitate a clear and complete description of the technical solution of the present invention and to facilitate understanding by those skilled in the art. It cannot be considered that these technical solutions are known to those skilled in the art just because these solutions are described in the background of the present invention.

[0006]
The inventor found that when the network device is configured with PUCCH-Spatial-relation-info for the terminal device, where PUCCH-Spatial-relation-info contains multiple entries, as shown in FIG. -relation-info (RRC configuration completed) until the MAC-CE signal is activated or indicates one of the entries, the network device's indication of the terminal device's uplink beam is ambiguous, as shown in Figure 2, in this case, the terminal device It is not clear which beam to upload. In addition, when the network device does not configure PUCCH-Spatial-relation-info for the terminal device, the terminal device may not be clear which beam to upload.

[0070]
Various embodiments of the present invention will be described below with reference to the drawings. These embodiments are only exemplary and are not limitations of the present invention.
[0071]
Example 1
[0072]
This embodiment provides an uplink signal transmission method, which is applied to a terminal device. FIG. 4 is a schematic diagram of the uplink signal transmission method of this embodiment. Please refer to FIG. 4, the method includes:
[0073]
Step 401: When the network device is configured with the first information related to the spatial relationship of the uplink signal, but the spatial relationship of the uplink signal has not yet taken effect, the terminal device uses the same airspace transmission as the transmitted signal or the received signal The filter or the spatial domain transmission filter associated with the predetermined entry in the first information is used to send the uplink signal.
[0074]
In this embodiment, the first information is, for example, the aforementioned PUCCH-Spatial-relation-info. As described above, the first information may have multiple entries or one entry, and each entry indicates or is associated with one Spatial Relations. For convenience of description, this embodiment only describes the case where the first information includes multiple entries.
[0075]
In this embodiment, as described in the background art, in the case where the first information has multiple entries, because which entry to use also requires the network device to indicate or activate through the MAC-CE, therefore, the network device has not been activated or In the case of indicating an item that needs to be used, that is, when the spatial relationship of the upstream signal has not yet taken effect, the terminal device may use the same spatial domain transmission filter (spatial domain transmission filter) or use as the transmitted signal or the received The spatial domain transmission filter associated with the predetermined entry in the first information sends an upstream signal. Thus, the terminal device can use an appropriate spatial domain transmission filter to transmit the uplink signal when the uplink beam is uncertain according to the configuration of the network device, which solves the problem that the terminal device cannot transmit the uplink signal when the uplink beam is uncertain.
[0076]
In other embodiments, the spatial relationship of the uplink signal has not yet taken effect, or it may be another situation, for example, the terminal device does not receive the above configuration of the network device, or, although the terminal device receives the above configuration of the network device, it is not successfully obtained The above-mentioned first information, etc., in these cases, the terminal device may also use the same spatial domain transmission filter as the transmitted signal or the received signal to transmit the uplink signal.
[0077]
In this embodiment, the network device may configure the above-mentioned first information for the terminal device through RRC signaling, but this embodiment is not limited to this, and the above-mentioned first information may also be configured through other signaling. For convenience of description, in this embodiment, RRC signaling is used as an example, and the configuration of the first information is referred to as an RRC configuration. The RRC configuration here cannot be understood as a configuration of RRC signaling other than the configuration of the first information.
[0078]
In this embodiment, the above configuration may be the initial configuration of the first information, or it may be the reconfiguration of the first information after the beam fails and recovers successfully, or it may be the first information after the cell handover is successful Initial configuration. The above-mentioned initial configuration means that the first information has not been configured for the terminal device before this configuration.
[0079]
FIG. 5 is a schematic diagram of initial configuration of the first information (PUCCH-Spatial-relation-info). As shown in FIG. 5, in this scenario, the terminal device may have just completed the initial access process. The initial configuration of the network device is to indicate or activate one of the entries through the MAC-CE. During this time, the network device's indication of the uplink beam is ambiguous, called the ambiguous interval 1, in which the terminal device can use and have sent The spatial transmission filter with the same signal or the received signal or the spatial transmission filter associated with the predetermined entry in the first information is used to send the uplink signal.
[0080]
For example, the terminal device may use the same spatial domain transmission filter as the first message (msg.1) in the random access process to send the uplink signal. In the scenario shown in FIG. 5, the successful initial access indicates that the uplink beam of msg1 is reliable. Using the beam of msg1 in the above time period (fuzzy interval) can ensure the success rate.
[0081]
For another example, the terminal device may use the same spatial domain transmission filter as the third message (msg.3) in the random access process to send the uplink signal. In the scenario shown in FIG. 5, similar to msg.1, the successful initial access indicates that the uplink beam of msg3 is reliable. Using the beam of msg3 in the above time period (fuzzy interval) can also ensure the success rate.
[0082]
For another example, the terminal device may use the spatial domain transmission filter associated with the pre-specified entry in the first information to send the uplink signal. The pre-specified entry may be pre-defined or pre-configured, for example, pre-defined or pre-configured as the first entry, whereby the terminal device may use the spatial transmission filter associated with the first entry to send in the above-mentioned fuzzy interval Uplink signal. This not only solves the problem that the terminal device cannot determine the uplink beam in the above-mentioned fuzzy interval, but also reduces the signaling overhead.
[0083]
For another example, the terminal device may use the spatial domain transmission filter associated with the default entry configured in the first information to send the uplink signal. In this example, unlike the previous example, the network device may further configure a default entry for the first information, and the terminal device may use the airspace transmission filter associated with the configured default entry to send uplinks in the above-mentioned fuzzy interval signal. Therefore, the uplink beam can have a larger selection range, and the configuration of the first information will be more flexible.
[0084]
For another example, the terminal device may use the same spatial domain transmission filter as the received broadcast signal (PBCH) to transmit the uplink signal. In this example, the principle of channel reciprocity is used. In the presence of channel reciprocity, the corresponding uplink beam transmitted by the spatial domain transmission filter that successfully receives the PBCH is reliable, and the terminal device can use this spatial domain transmission filter Device, which can guarantee the success rate.
[0085]
For another example, the terminal device may use the same spatial domain transmission filter as the received synchronization signal (SS) to transmit the uplink signal. In this example, similar to the previous example, the principle of channel reciprocity is also used, and the same spatial domain transmission filter as the received SS can also be used to ensure the success rate.
[0086]
In addition, in the scenario shown in FIG. 5, before the initial configuration, the network device does not have any indication of the spatial relationship (uplink beam) of the uplink signal. In this case, the network device’s indication of the uplink beam is also ambiguous. In the fuzzy interval 2, in the fuzzy interval 2, the terminal device may use the same spatial domain transmission filter as the transmitted signal or the received signal to transmit the uplink signal.
[0087]
For example, the terminal device may use the same spatial domain transmission filter as the first message (msg.1) in the random access process to send the uplink signal. In this example, before the above-mentioned initial configuration, the terminal device did not obtain the configuration about the above-mentioned first information, so the indication of the network device regarding the uplink beam is also ambiguous. However, at this time, the terminal device may have completed the initial access. Therefore, During this time, it can use the same spatial domain transmission filter as msg.1 to send the upstream signal. Similarly, the terminal device may also use the same spatial domain transmission filter as the third message (msg.3) in the random access process to send the uplink signal. Alternatively, the terminal device may use the same spatial domain transmission filter as the received broadcast signal (PBCH) to transmit the uplink signal, or the terminal device may use the same spatial domain filter as the received synchronization signal (SS) to transmit the uplink signal. The principle of implementation is the same as described above, and the description is omitted here.
[0088]
In the scenario shown in FIG. 5, the uplink signal may be an uplink control signal (PUCCH), which may be used to carry information such as ACK/NACK feedback of the downlink data channel (PDSCH), CSI reporting, and so on. In addition, the uplink signal may be a sounding reference signal (SRS) or the like.
[0089]
FIG. 6 is a schematic diagram of reconfiguring the first information after the beam fails and recovers successfully. As shown in FIG. 6, in this scenario, the terminal device has just successfully recovered from the beam failure, and the original uplink beam indicator (for example, The uplink beam signal for the uplink control signal (PUCCH) and/or uplink data signal (PUSCH) is already unreliable, and the uplink beam indication for the PUCCH and/or PUSCH needs to be reconfigured and/or activated and/or indicated. Thus, from the successful restoration to the reconfiguration of the first information, and from the reconfiguration of the first information to the activation or indication of one of the entries, the uplink beam indication is ambiguous, which is called ambiguous interval 3 and ambiguous interval 4, respectively.
[0090]
In this embodiment, in the fuzzy interval 4, the terminal device may use the same spatial domain transmission filter as the transmitted signal or the received signal or use the spatial domain transmission filter associated with the predetermined entry in the first information to send the uplink signal .
[0091]
For example, the terminal device may use the same spatial domain transmission filter as the transmit beam failure recovery request (BFRQ) to transmit the uplink signal. In the scenario shown in FIG. 6, the terminal device has just successfully recovered from the beam failure, indicating that the BFRQ uplink beam is reliable, and the BFRQ beam is used to transmit the uplink signal in the fuzzy interval 4 to ensure the success rate.
[0092]
For another example, the terminal device may use the same spatial domain transmission filter as the successful reception beam failure recovery response control resource set (BFR-CORESET) to transmit the uplink signal. In this example, the principle of channel reciprocity is also used, and the successful reception of BFR-CORESET in the downstream can ensure the transmission of the upstream signal.
[0093]
In addition, the terminal device may also use the air domain transmission filter associated with the entry specified in the first information to send the uplink signal, or the terminal device may also use the air domain transmission filter associated with the default entry configured in the first information to send The uplink signal, or the terminal device may use the same spatial domain transmission filter as the received PBCH to transmit the uplink signal, or the terminal device may also use the same spatial domain transmission filter as the received SS to transmit the uplink signal. The principle of implementation is the same as described above, and the description is omitted here.
[0094]
In this embodiment, in the fuzzy interval 3, the terminal device may use the same spatial domain transmission filter as the transmitted signal or the received signal to transmit the uplink signal.
[0095]
For example, the terminal device may use the same airspace transmission filter as the transmit beam failure recovery request (BFRQ) to transmit the uplink signal, or the terminal device may use the same airspace transmission as the successful receive beam failure recovery response control resource set (BFR-CORESET) The filter sends upstream signals. The principle of implementation is the same as described above, and the description is omitted here.
[0096]
In the scenario shown in FIG. 6, since the reconfiguration of the first information described above occurs after the beam fails and recovers successfully, the uplink signal that needs to be indicated by the uplink beam may be PUCCH, PUSCH, or both. In addition, PUCCH can carry RRC configuration response, beam training, beam reporting and other functions, and PUSCH can carry uplink data.
[0097]
7a and 7b are schematic diagrams of initial configuration of the first information in a cell handover scenario.
[0098]
In the scenario shown in FIG. 7a, the successful cell switching occurs before the initial configuration of the first information, that is, the terminal device successfully switches the cell, and the initial configuration of the first information is completed in the new cell. In this scenario, from From the completion of the cell handover to the completion of the initial configuration of the first information, and from the completion of the initial configuration of the first information to the activation of the network device or indicating which of the entries to use, the network device's indication of the uplink beam is also ambiguous, called the fuzzy interval 5 and blur interval 6.
[0099]
In the fuzzy interval 5, the terminal device can use the same spatial domain transmission filter as the received signal to send the uplink signal. For example, the terminal device may use the same spatial domain filter as the received broadcast signal (PBCH) to transmit the uplink signal, or the terminal device may use the same spatial domain transmission filter as the received synchronization signal (SS) to transmit the uplink signal. The principle of implementation is the same as described above, and the description is omitted here.
