In order to facilitate understanding of the technical solutions of the embodiments of the present application, the technical solutions of the present application are described in detail below through specific examples. The following related technologies may be optionally combined with the technical solutions of the embodiments of the present application as optional solutions, and all of them belong to the protection scope of the embodiments of the present application. The embodiment of the present application includes at least part of the following contents.

In order to better understand the embodiment of the present application, the relevant uplink panel of the present application will be described.

With the continuous evolution of antenna packaging technology, multiple antenna elements (antenna elements) can be nested and combined with chips to form an antenna panel or antenna array block (panel), which makes it possible to configure multiple low-correlation panels on the transmitter. possible. Through the multi-antenna beam property technology, the energy of the transmitted signal is concentrated in a certain direction for transmission, which can effectively improve coverage and improve communication performance. Multiple panels can independently form transmission beams, so that a terminal transmitter can simultaneously transmit data streams on multiple panels through different beams to improve transmission capacity or reliability.

The terminal needs to notify the network side of the number of configured antenna panels in the capability report. At the same time, the terminal may also need to notify the network side whether it has the ability to simultaneously transmit signals on multiple antenna panels. Since the channel conditions corresponding to different panels are different, different panels need to adopt different transmission parameters according to their respective channel information. In order to obtain these transmission parameters, different Sounding Reference Signal (SRS) resources need to be configured for different panels to obtain uplink channel information. For example, in order to perform uplink beam management, an SRS resource set may be configured for each panel, so that each panel performs beam management separately and determines an independent analog beam. In order to obtain the precoding information used for physical uplink shared channel (Physical Uplink Shared Channel, PUSCH) transmission, it is also possible to configure an SRS resource set for each panel, which is used to obtain the beam used by the PUSCH transmitted on the panel, the precoding vector, Transmission parameters such as the number of transmission layers. At the same time, multi-panel transmission can also be applied to the Physical Uplink Control Channel (PUCCH), that is, the information carried by the same PUCCH resource or the PUCCH resource on the same time domain resource can be sent to the network side through different panels at the same time. Among them, each panel can have its own panel identification (Identity, ID), which is used to associate different signals transmitted on the same panel, that is, the terminal can think that signals associated with the same panel ID need to be transmitted from the same panel.

In order to better understand the embodiments of the present application, the uplink beam management related to the present application will be described.

In NR, terminals can use analog beams to transmit uplink data and uplink control information. The terminal can perform uplink beam management based on the SRS signal, so as to determine the analog beam used for uplink transmission. Specifically, the network may configure an SRS resource set 1 for the terminal, and the set includes N SRS resources (N>1). The terminal may use different beams to send the N SRS resources, and the network side measures the reception quality of the N SRS resources respectively, and selects K SRS resources with the best reception quality. The network side may further configure an SRS resource set 2, which includes K SRS resources, and make the terminal transmit the SRS resources in the set 2 using the analog beam used by the K SRS resources selected in the set 1. This can be realized by configuring the K SRS resources selected in the set 1 as reference SRS resources of the K SRS resources in the set 2 respectively. At this time, based on the SRS transmitted by the terminal in the SRS resource set 2, the network side can select an SRS resource with the best reception quality, and notify the corresponding SRS resource indicator (SRS resource indicator, SRI) to the terminal. After receiving the SRI, the terminal determines the analog beam used by the SRS resources indicated by the SRI as the analog beam used for transmitting the PUSCH.

In order to determine the beam used for PUCCH transmission, NR uses radio resource control (Radio Resource Control, RRC) + media access control (Media Access Control, MAC) signaling to instruct each PUCCH resource to transmit uplink control information ( The beam used by Uplink Control Information, UCI). Specifically, N pieces of PUCCH spatial correlation information (PUCCH-spatialrelationinfo) are firstly configured through high-layer signaling, and then spatial correlation information corresponding to each PUCCH resource is determined from the N pieces of information through MAC signaling.

In order to better understand the embodiments of the present application, the uplink non-coherent transmission related to the present application will be described.

In the NR system, downlink and uplink non-coherent transmission based on multiple transmission and reception points (Transmission Reception Point, TRP) is introduced. Among them, the backhaul (backhaul) connection between TRPs can be ideal or non-ideal. Under ideal backhaul, TRPs can quickly and dynamically exchange information. It can conduct information exchange quasi-statically. In downlink non-coherent transmission, multiple TRPs can use different control channels to independently schedule multiple Physical Downlink Shared Channel (PDSCH) transmissions of a terminal, or use the same control channel to schedule transmissions of different TRPs. The data of different TRPs uses different transport layers, and the latter can only be used in the case of ideal backhaul.

In uplink non-coherent transmission, different TRPs can also independently schedule the PUSCH transmission of the same terminal. Different PUSCH transmissions can be configured with independent transmission parameters, such as beam, precoding matrix, number of layers, etc. The scheduled PUSCH transmissions can be transmitted in the same slot or in different slots. If the terminal is scheduled to transmit two PUSCHs simultaneously in the same time slot, it needs to determine how to perform the transmission according to its own capabilities. If the terminal is configured with multiple panels and supports simultaneous transmission of PUSCHs on multiple panels, the two PUSCHs can be transmitted at the same time, and the PUSCHs transmitted on different panels are aligned with the corresponding TRP for analog shaping, so that they can be distinguished through the space domain Different PUSCHs provide uplink spectrum efficiency (a in Figure 2). If the terminal has only a single panel, or does not support simultaneous transmission of multiple panels, PUSCH can only be transmitted on one panel. Similar to the downlink, the PUSCH transmitted by different TRPs can be scheduled based on multiple downlink control information (Downlink Control Information, DCI), and these DCIs can be carried by different control resource sets (Control Resource Set, CORESET). Specifically, multiple CORESET groups are configured on the network side, and each TRP is scheduled using a CORESET in its own CORESET group, that is, different TRPs can be distinguished by the CORESET group. For example, a network device may configure a CORESET group index for each CORESET, and different indexes correspond to different TRPs. Similarly, PUSCHs transmitted to different TRPs can be scheduled based on a single DCI. At this time, the DCI needs to indicate beams and demodulation reference signal (Demodulation Reference Signal, DMRS) ports ( As shown in b) in Figure 2, different transmission layers of a PUSCH can be transmitted on different panels.

A similar method can also be used for PUCCH transmission. That is, the terminal can configure two PUCCHs to be transmitted on different panels at the same time, and the beams used by different panels are different, and the respective space related information is notified to the terminal, as shown in FIG. 3 .

In order to better understand the embodiments of the present application, the problems solved in the present application will be described.

The terminal cannot use the same panel to transmit multiple uplink signals on the same physical resource, but it can use different panels to transmit multiple uplink signals at the same time. When multiple uplink signals scheduled or configured by the network device conflict, the terminal cannot determine which signals need to be transmitted on the same panel and which can be transmitted on different panels, so it cannot decide which signals need to be discarded and which can be transmitted .

Based on the above problems, this application proposes a transmission scheme for uplink signals. In the case that the time domain resources of multiple uplink signals overlap, the terminal device can determine multiple uplink signals according to the spatial correlation information corresponding to the multiple uplink signals. The uplink signal that can be transmitted in the middle, thus supporting simultaneous transmission on multiple panels, improves the spectral efficiency of the uplink.

The technical scheme of the present application is described in detail below through specific examples.

FIG. 4 is a schematic flowchart of a wireless communication method 200 according to an embodiment of the present application. As shown in FIG. 4 , the wireless communication method 200 may include at least part of the following content:

S210. The terminal device determines the uplink signals transmitted in the multiple uplink signals according to the spatial correlation information respectively corresponding to the multiple uplink signals; where the time domain resources of the multiple uplink signals overlap.

In the embodiment of the present application, the time domain resources of the multiple uplink signals overlap, that is, the transmission of the multiple uplink signals may collide or collide. In this case, the terminal device determines the uplink signals transmitted among the multiple uplink signals according to the spatial correlation information respectively corresponding to the multiple uplink signals, that is, the terminal device can determine the multiple uplink signals according to the spatial correlation information respectively corresponding to the multiple uplink signals Which of the uplink signals needs to be transmitted and which needs to be discarded, so as to support simultaneous transmission on multiple panels and improve the uplink spectrum efficiency.

In this embodiment of the present application, an "antenna panel" may also be referred to as an "antenna array block" or a "panel", which is not limited in this application.

In some embodiments, the time-domain resources of the multiple uplink signals overlap, for example, the physical resources of the multiple uplink signals completely overlap, or at least part of the orthogonal frequency-division multiplexing (Orthogonal frequency-division multiplexing) of the multiple uplink signals , OFDM) symbols overlap.

In some embodiments, the terminal device discards the uplink signals that are not transmitted among the multiple uplink signals.

In some embodiments, the spatial correlation information is used to determine the transmit beam and/or transmit antenna panel of the uplink signal. For example, the terminal device may determine an indicated reference signal according to the spatial correlation information corresponding to the uplink signal, and the terminal device uses the transmission beam or the reception beam of the reference signal as the transmission beam of the uplink signal, or the terminal device adopts the The sending panel or receiving panel of the reference signal sends the uplink signal.

In some embodiments, the spatial correlation information is used to determine the transmission beam (spatial transmission filter) of the uplink signal. At this time, the terminal device can determine the uplink signal according to the reference signal used to determine the transmission beam (spatial transmission filter). The transmission timing of the space correlation information may additionally include a reference signal for determining the uplink timing.

In some embodiments, the spatial correlation information may be indicated through higher layer signaling or DCI. For example, for PUCCH, it can be indicated by MAC layer signaling; for PUSCH, it can be indicated by DCI; for SRS, it can be indicated by RRC signaling.

In this embodiment of the present application, the sending beam may also be referred to as a spatial domain transmission filter (Spatial domain transmission filter or Spatial domain filter for transmission) or a spatial relationship (Spatial relation) or a spatial configuration (spatial setting). The receiving beam can also be called a spatial domain reception filter (Spatial domain reception filter or Spatial domain filter for reception) or a spatial reception parameter (Spatial Rx parameter). The space-related information is information related to reception/transmission in the space domain. Since the space domain receiving/transmitting information is directly related to the beam. The space-related information is also information related to beams (Beam).

In some embodiments, the spatial correlation information is SRI, or, the spatial correlation information is SRS spatial correlation information (SRS-spatialrelationinfo), or, the spatial correlation information is PUCCH spatial correlation information (PUCCH-spatialrelationinfo), or, the The space-related information is the (Transmission Configuration Indicator, TCI) status.

In some embodiments, the spatial correlation information corresponding to different uplink signals among the multiple uplink signals may be the same or different. This application is not limited to this.

For example, the spatial correlation information corresponding to each of the multiple uplink signals is SRS-spatialrelationinfo. For another example, the spatial correlation information corresponding to a part of the multiple uplink signals is SRS-spatialrelationinfo, and the spatial correlation information corresponding to the other part of the uplink signals is the TCI state.

In some embodiments, the multiple uplink signals include but are not limited to at least one of the following: SRS, PUCCH, and PUSCH. Different uplink signals among the multiple uplink signals may be the same or different, which is not limited in this application.

For example, the multiple uplink signals are all PUSCH or SRS or PUCCH. For another example, some of the multiple uplink signals are SRS, some of the uplink signals are PUSCH, and some of the uplink signals are PUCCH.

In some embodiments, the terminal device determines the uplink signal transmitted in the multiple uplink signals according to the reference signal or the antenna panel identification (panel ID) indicated by the spatial correlation information respectively corresponding to the multiple uplink signals. That is, in the above S210, the terminal device determines the uplink signal transmitted among the multiple uplink signals according to the reference signal or the antenna panel identifier indicated by the spatial correlation information respectively corresponding to the multiple uplink signals.

In some embodiments, the reference signal may be a synchronization signal block (Synchronization Signal Block, SSB) or a channel state information reference signal (Channel State Information Reference Signal, CSI-RS) or a sounding reference signal (Sounding Reference Signal, SRS).

It should be noted that the SSB may also be called a synchronization signal/physical broadcast channel block (SS/PBCH block).

Specifically, for example, for a certain uplink signal among the multiple uplink signals, when the reference signal indicated by the spatial correlation information corresponding to the uplink signal is SSB or CSI-RS, the terminal device uses the receiving beam or receiving panel of the reference signal The uplink signal is transmitted; when the reference signal indicated by the spatial correlation information corresponding to the uplink signal is an SRS, the terminal device uses the transmission beam or transmission panel of the reference signal to transmit the uplink signal.

In some embodiments, before S210, the terminal device may receive multiple reference signal resource sets configured by the network device, different reference signal resource sets use different panels to send or receive reference signals, and the spatial correlation information may indicate multiple reference signal resources A reference signal resource in a reference signal resource set in the set, so that the panel is determined through the reference signal resource set. For example, the network device can be configured with multiple CSI-RS resource sets, and different CSI-RS resource sets are received on different panels; or, the network device can be configured with multiple CSI-RS resource sets, and different CSI-RS resource sets are in Send on different panels; or, the network device can indicate multiple physical cell identifiers (Physical Cell Identifier, PCI), and the SSB associated with each PCI is used as a reference signal resource set, so that different reference signal resource sets are in different panels to receive.

Specifically, for PUSCH, the space related information may be the SRI included in the DCI, which is used to indicate an SRS resource; for PUCCH, the space related information may be the PUCCH space related information indicated by high-layer signaling, which is used to indicate a CSI-RS or SSB or SRS; for SRS, the space related information may be the SRS space related information indicated by high layer signaling, which is used to indicate a CSI-RS or SSB or SRS. For SRS/PUCCH/PUSCH, space-related information can also be TCI status, which can be configured by high-layer signaling and indicated to the terminal device through Media Access Control Control Element (MAC CE) or DCI.

Specifically, each space-related information may include an indication information of a Panel ID, which is used to indicate the panel used for transmission, for example, indication values 0 and 1 respectively correspond to different panels. The set of reference signal resources here may be a set of SRS resources or a set of CSI-RS resources or a set of SSBs carrying the same PCI. On the other hand, an upstream signal with a lower priority will be discarded without transmission.

Mode 2, if the spatial correlation information of the first uplink signal and the second uplink signal indicate reference signals in different reference signal resource sets, or if the spatial correlation information of the first uplink signal and the second uplink signal indicate different panel IDs, Then the terminal device transmits two uplink signals at the same time. Further, the terminal device may simultaneously transmit the two uplink signals through two different panels.

Mode 3, if the spatial correlation information of the first uplink signal and the second uplink signal indicates the same reference signal, the terminal device determines not to transmit the first uplink signal and the second uplink signal, or only transmits the priority of the two uplink signals A higher up signal. In other words, the terminal device does not expect the spatial correlation information of two overlapping uplink signals in the time domain to indicate the same reference signal. If this occurs, the end device treats it as an error case and does not transmit the corresponding signal, or, which signal is transmitted depends on the end device implementation.

In some embodiments, the multiple uplink signals include a third uplink signal and a fourth uplink signal; wherein, the third uplink signal corresponds to the first spatial correlation information and the second spatial correlation information, and the fourth uplink signal corresponds to the third space-related information.

In the case that the first space-related information and the third space-related information indicate the same antenna panel identifier, the terminal device determines the multiple The uplink signal transmitted in the uplink signal.

That is, in the case where the first spatial correlation information and the third spatial correlation information indicate different reference signals in the same reference signal resource set, it may not be considered whether the second spatial correlation information and the third spatial correlation information Different reference signals in the same set of reference signal resources are indicated. Or, in the case that the first space-related information and the third space-related information indicate the same antenna panel identifier, whether the second space-related information and the third space-related information indicate the same antenna panel may not be considered logo.

In some embodiments, when the priority of the third uplink signal is higher than the priority of the fourth uplink signal, the terminal device determines to only transmit the third uplink signal. Or, in a case where the priority of the third uplink signal is equal to the priority of the fourth uplink signal, the terminal device determines to transmit only the third uplink signal.

In some embodiments, when the priority of the third uplink signal is lower than the priority of the fourth uplink signal, the terminal device determines to transmit the third uplink signal and the fourth uplink signal at the same time, or, the The terminal device determines to only transmit the fourth uplink signal. Or, when the priority of the third uplink signal is equal to the priority of the fourth uplink signal, the terminal device determines to transmit the third uplink signal and the fourth uplink signal at the same time, or the terminal device determines to transmit only The fourth uplink signal.

Specifically, for example, when the terminal device determines to only transmit the third uplink signal, the terminal device uses the first spatial correlation information and the second spatial correlation information to transmit the third uplink signal on two antenna panels simultaneously.

Specifically, for example, when the terminal device determines to transmit the third uplink signal and the fourth uplink signal at the same time, the terminal device uses the second spatial correlation information to transmit the third uplink signal on one antenna panel, and transmit the third uplink signal on the other antenna panel. The antenna panel transmits the fourth uplink signal by using the third spatial correlation information.

In some embodiments, the multiple uplink signals include a third uplink signal and a fourth uplink signal; wherein, the third uplink signal corresponds to the first spatial correlation information and the second spatial correlation information, and the fourth uplink signal corresponds to the third space-related information. That is, the third uplink signal is configured with two pieces of spatial correlation information, and the fourth uplink signal is configured with one piece of spatial correlation information. In this case, the above S210 may specifically include:

In a case where the two spatial correlation information corresponding to the third uplink signal and the spatial correlation information corresponding to the fourth uplink signal indicate reference signals in different reference signal resource sets, the terminal device determines not to transmit the third uplink signal and the fourth uplink signal; or,

In the case that the two spatial correlation information corresponding to the third uplink signal and the spatial correlation information corresponding to the fourth uplink signal indicate different antenna panel identifiers, the terminal device determines not to transmit the third uplink signal and the fourth uplink signal. up signal.

Example 2, the network device schedules the terminal device to transmit the third uplink signal and the fourth uplink signal, and the time domain resources of the third uplink signal and the fourth uplink signal overlap, for example, the physical resources of the third uplink signal and the fourth uplink signal Completely overlap, or some OFDM symbols overlap. Among them, the third uplink signal is configured with two spatially related information, which are respectively recorded as the first spatially related information and the second spatially related information, and each of the fourth uplink signals is configured with one piece of spatially related information, which is recorded as the third spatially related information , one of the following manners 4 to 6 may be used to determine which uplink signals to transmit.

Way 4: If the third spatial correlation information corresponding to the fourth uplink signal and one of the spatial correlation information corresponding to the third uplink signal indicate the same reference signal, the terminal device transmits the third uplink signal and the fourth uplink signal at the same time. Wherein, the terminal device uses the first spatial correlation information and the second spatial correlation information to simultaneously transmit the third uplink signal on the two panels respectively, and transmit the fourth uplink signal on one of the panels. For example, the terminal device uses the first spatial correlation information to transmit the third uplink signal and the fourth uplink signal on one panel, and uses the second spatial correlation information to transmit the third uplink signal on another panel.

Mode 5, if the third spatial correlation information corresponding to the fourth uplink signal and the first spatial correlation information corresponding to the third uplink signal indicate different reference signals in the same reference signal resource set, or if the fourth uplink signal corresponds to the first spatial correlation information The first space-related information corresponding to the third space-related information and the third uplink signal indicates the same panel ID, then the terminal device determines whether to transmit the third uplink signal and the fourth uplink signal at the same time according to the priorities of the third uplink signal and the fourth uplink signal Four uplink signals.

In one embodiment, if the priority of the third uplink signal is higher than that of the fourth uplink signal, the terminal device uses the first spatial correlation information and the second spatial correlation information to transmit the third uplink signal on the two panels respectively, and The fourth uplink signal is not transmitted.

In one embodiment, if the priority of the third uplink signal is lower than that of the fourth uplink signal, the terminal device uses the second spatial correlation information to transmit the third uplink signal on one panel, and transmit the fourth uplink signal on another panel. The uplink signal, that is, the terminal device does not use the first spatial correlation information to transmit the third uplink signal. This embodiment can be used in the case where the third uplink signal uses two pieces of spatial correlation information for repeated transmission, that is, different spatial correlation information is used for different repeated transmissions. At this time, if the priority of the third uplink signal is lower, the repeated transmission on the same panel as the fourth uplink signal may be discarded, and the repeated transmission on another panel will not be affected.

In an implementation manner, if the priority of the third uplink signal is lower than that of the fourth uplink signal, the terminal device transmits the fourth uplink signal on one panel and does not transmit the third uplink signal. That is, the third uplink signal can be discarded. This embodiment can be used in the case where the terminal equipment uses two spatial correlation information to transmit different transmission layers of the PUSCH (that is, the third uplink signal), for example, different layers use different spatial correlation information. At this time, if the priority of the third uplink signal is lower than that of the fourth uplink signal, the third uplink signal will be completely discarded.

Mode 6, if the third spatial correlation information corresponding to the fourth uplink signal and the two spatial correlation information corresponding to the third uplink signal indicate reference signals in different reference signal resource sets, or if the third spatial correlation information corresponding to the fourth uplink signal The spatial correlation information and the two spatial correlation information corresponding to the third uplink signal indicate different panel IDs, for example, the first spatial correlation information corresponding to the third uplink signal indicates the reference signal in the first reference signal resource set, and the second The second spatial correlation information corresponding to the three uplink signals indicates the reference signal in the second reference signal resource set, and the third spatial correlation information corresponding to the fourth uplink signal indicates the reference signal in the third reference signal resource set, then The terminal device may regard it as an error case (error case), and determine not to transmit the third uplink signal and the fourth uplink signal. Or, the first spatial correlation information corresponding to the third uplink signal indicates the first panel, the second spatial correlation information corresponding to the third uplink signal indicates the second panel, and the third spatial correlation information corresponding to the fourth uplink signal indicates If the third panel is selected, the terminal device can regard it as an error case and determine not to transmit the third uplink signal and the fourth uplink signal. That is to say, the terminal device does not expect the spatial correlation information of the two overlapping uplink signals in the time domain to indicate more than the reference signals in the two reference signal resource sets, or the terminal device does not expect the information of the two overlapping uplink signals in the time domain Spatial related information indicates more than two different panel IDs.

It should be noted that if both the third uplink signal and the fourth uplink signal are configured with two pieces of spatial correlation information, each piece of spatial correlation information of the fourth uplink signal can be judged according to the above methods 4 to 6, Determine the uplink signal for final transmission.

Example 3, the network device schedules the terminal device to transmit three uplink signals, respectively denoted as uplink signal 1 to uplink signal 3, and the time domain resources of the three uplink signals overlap, for example, the physical resources of the three uplink signals completely overlap, or Some OFDM symbols overlap. Wherein, the three uplink signals are all configured with a piece of spatial correlation information, and one of the following manners 7 to 11 may be used to determine which uplink signals to transmit.

Mode 7, if the spatial correlation information corresponding to uplink signal 1 and uplink signal 2 indicates the same reference signal, and the spatial correlation information corresponding to uplink signal 1 and uplink signal 2 is different from the reference signal indicated by the spatial correlation information corresponding to uplink signal 3 or, the spatial correlation information corresponding to uplink signal 1 and uplink signal 2 and the spatial correlation information corresponding to uplink signal 3 indicate different panel IDs, then the terminal device uses the same beam and panel to transmit uplink signal 1 and uplink Signal 2, and transmit uplink signal 3 on another panel.

Mode 8, if the spatial correlation information corresponding to uplink signal 1 and uplink signal 2 indicates the same reference signal, and the spatial correlation information corresponding to uplink signal 1 and uplink signal 2 and the reference signal indicated by the spatial correlation information corresponding to uplink signal 3 belong to the same Different reference signals in the reference signal resource set, or the spatial correlation information corresponding to uplink signal 1 and uplink signal 2 and the spatial correlation information corresponding to uplink signal 3 indicate the same panel ID, then the terminal device according to the priorities of the three signals, Determine the upstream signals transmitted on different panels.

Specifically, for example, if the priority of uplink signal 1 and uplink signal 2 is higher than that of uplink signal 3, the terminal device uses the same panel and beam (beam) to transmit uplink signal 1 and uplink signal 2, and does not transmit uplink signal 3.

As another specific example, if the priority of the uplink signal 3 is higher than that of the uplink signal 1 and the uplink signal 2, the terminal device only transmits the uplink signal 3 .

Mode 9, if the spatial correlation information of the three uplink signals indicates different reference signals in the same reference signal resource set, or the spatial correlation information of the three uplink signals indicates the same panel ID, the terminal device only transmits the priority of the three uplink signals An uplink signal with the highest level.

Mode 10, if the spatial correlation information corresponding to uplink signal 1 and uplink signal 2 indicates different reference signals in the same reference signal resource set, or the spatial correlation information corresponding to uplink signal 1 and uplink signal 2 indicates the same panel ID, and the uplink If the spatial correlation information corresponding to signal 1 and uplink signal 2 is different from the reference signal resource set of the reference signal indicated by the spatial correlation information corresponding to uplink signal 3 or the indicated panel ID is different, then the terminal device transmits uplink signal 1 and uplink signal 1 on one panel. An uplink signal with a higher priority in signal 2 transmits uplink signal 3 on another panel.

Mode 11, if the spatial correlation information corresponding to the three uplink signals indicates reference signals in different reference signal resource sets, or if the spatial correlation information corresponding to the three uplink signals indicates different panel IDs, the terminal device can treat it as an error In an error case, it is determined not to transmit the three uplink signals, or, which uplink signal to transmit is implemented by the terminal device itself. That is to say, the terminal device does not expect the spatial correlation information of multiple overlapping uplink signals in the time domain to indicate reference signals in more than two reference signal resource sets, or the terminal device does not expect the information of the multiple overlapping uplink signals in the time domain Spatial related information indicates more than two different panel IDs.
