     The embodiments of the disclosure provide an uplink signal transmission method.  FIG. 2  is a flowchart of an uplink signal transmission method according to an embodiment of the disclosure. As shown in  FIG. 2 , the method includes the following operations. 
     In operation  201 , a terminal receives associated reference signals configured by a network device respectively for two uplink signals to be transmitted. 
     In operation  202 , in response to the reference signals respectively associated with the two uplink signals to be transmitted meeting a preset condition, the terminal simultaneously sends the two uplink signals. 
     In the embodiment, the two uplink signals may be configured to be transmitted on the same time-domain resource. In an implementation mode, the two uplink signals are configured to be transmitted on the same Orthogonal Frequency Division Multiplexing (OFDM) symbols or configured to be transmitted in the same slot. 
     In the embodiment, each of the two uplink signals may be one of the following signals: a Sounding Reference Signal (SRS), a Physical Uplink Control Channel (PUCCH), a Physical Uplink Shared Channel (PUSCH), a Physical Uplink Control Channel Demodulation Reference Signal (PUCCH DMRS), a Physical Uplink Shared Channel Demodulation Reference Signal (PUSCH DMRS) and a Phase Tracking Reference Signal (PTRS). 
     In the embodiment, the reference signal associated with each of the two uplink signals may be one of the following signals: a Synchronization Signal Block (SSB), an uplink PTRS, an SRS and a Channel State Information-Reference Signal (CSI-RS). The reference signals respectively associated with the two uplink signals may be configured by the network device. 
     In the embodiment, descriptions are made based on whether the reference signals respectively associated with the two uplink signals meet the preset condition or not and specific implementation modes of transmission of the uplink signals by the terminal respectively. 
     In a first implementation mode, when the reference signals respectively associated with the two uplink signals are uplink PTRSs, the reference signals respectively associated with the two uplink signals to be transmitted meeting the preset condition may include that: ports of the uplink PTRSs respectively associated with the two uplink signals are different. 
     In an implementation mode, when the ports of the uplink PTRSs respectively associated with the two uplink signals are different, in this application scenario, the terminal may consider that the two uplink signals are required to be transmitted through different panels. In such case, if the network device configures the two uplink signals to be transmitted on the same time-domain resource, the terminal may simultaneously send the two uplink signals through different panels. 
     In the implementation mode, the method may further include that: when the ports of the uplink PTRSs respectively associated with the two uplink signals are the same, the terminal sends an uplink signal with a higher priority in the two uplink signals, or, the terminal does send neither of the two uplink signals. 
     Herein, when the ports of the uplink PTRSs respectively associated with the two uplink signals are the same, the terminal may consider that the two uplink signals can be transmitted through the same panel only. In such case, the terminal cannot simultaneously send the two uplink signals. If the network device configures the two uplink signals to be transmitted on the same time-domain resource, as an example, the terminal may determine an uplink signal with a higher priority from the two uplink signals according to a preset priority rule and only send the uplink signal with the higher priority, As another example, the terminal does send neither of the two uplink signals. For the second application scenario, if the network device configures the two uplink signals to be simultaneously transmitted, the terminal may process the present case as an error case and is not needed to send the two uplink signals according to a configuration of the network device. 
     In the implementation mode, the method may further include that: when a first uplink signal of the two uplink signals is a PUSCH or PUSCH DMRS scheduled by Downlink Control Information (DCI), the terminal determines a port of an uplink PTRS associated with the first uplink signal based on PTRS port indication information in the DCI, the first uplink signal being any one of the two uplink signals; and/or, when a second uplink signal of the two uplink signals is an uplink signal of other type than the PUSCH and PUSCH DMRS scheduled by the DCI, the terminal determines a port of an uplink PTRS associated with the second uplink signal based on a PTRS port corresponding to an SRS resource for an SRS that adopts a same beam as the second uplink signal. Herein, the network device may configure the SRS resource for the SRS that adopts a same beam as the second uplink signal and a PTRS port corresponding to each SRS resource in advance through high-layer signaling. The second uplink signal may be any one of the two uplink signals. 
     Herein, the beam is also called a spatial transmission filter. The SRS that adopts a same beam as the second uplink signal may also be called an SRS adopting the same spatial transmission filter as the second uplink signal. 
     In a second implementation mode, when the reference signals respectively associated with the two uplink signals are SRSs, the reference signals respectively associated with the two uplink signals to be transmitted meeting the preset condition may include that: SRS resources for the SRSs respectively associated with the two uplink signals belong to different SRS resource sets, or, SRS resources for the SRSs respectively associated with the two uplink signals correspond to different PTRS ports. 
     In an implementation mode, when the SRS resources for the SRSs respectively associated with the two uplink signals belong to different SRS resource sets, in this application scenario, the terminal may consider that the two uplink signals are required to be transmitted through different panels. In such case, if the network device configures the two uplink signals to be transmitted on the same time-domain resource, the terminal may simultaneously send the two uplink signals through different panels. As a second implementation mode, when the SRS resources for the SRSs respectively associated with the two uplink signals correspond to different PTRS ports, in this application scenario, the terminal may consider that the two uplink signals are required to be transmitted through different panels. In such case, if the network device configures the two uplink signals to be transmitted on the same time-domain resource, the terminal may simultaneously send the two uplink signals through different panels. Herein, the network device may configure a corresponding PTRS port for a SRS resource for each SRS in advance. 
     In the implementation mode, the method may further include that: when the SRS resources for the SRSs respectively associated with the two uplink signals belong to the same SRS resource set or when the SRS resources for the SRSs respectively associated with the two uplink signals correspond to the same PTRS port, the terminal sends the uplink signal with the higher priority in the two uplink signals, or, the terminal does send neither of the two uplink signals. 
     When the SRS resources for the SRSs respectively associated with the two uplink signals belong to the same SRS resource set or when the SRS resources for the SRSs respectively associated with the two uplink signals correspond to the same PTRS port, the terminal may consider that the two uplink signals can be transmitted through the same panel only. In such case, the terminal cannot simultaneously send the two uplink signals. If the network device configures the two uplink signals to be transmitted on the same time-domain resource, as an example, the terminal may determine the uplink signal with the higher priority in the two uplink signals according to the preset priority rule and only send the uplink signal with the higher priority. As another example, the terminal does send neither of the two uplink signals. In the second application scenario, if the network device configures the two uplink signals to be simultaneously transmitted, the terminal may process the present case as an error case and is not needed to send the two uplink signals according to the configuration of the network device. 
     In the implementation mode, the SRSs respectively associated with the two uplink signals are SRSs that adopt a same beam as respective uplink signals. Herein, the beam is also called a spatial transmission filter. The SRSs that adopt a same beam as the respective uplink signals may also be called SRSs adopting the same spatial transmission filter as the corresponding uplink signals. 
     In the implementation mode, the network device may configure the SRS resources for the SRSs adopting the same beams for the two uplink signals in advance through high-layer signaling respectively. 
     In the implementation mode, the method may further include that: when the first uplink signal of the two uplink signals is the PUSCH or PUSCH DMRS scheduled by the DCI, the terminal determines the SRS resource for the SRS associated with the first uplink signal based on SRS resource indication information in the DCI, the first uplink signal being any one of the two uplink signals; and when the second uplink signal of the two uplink signals is an uplink signal of other type than the PUSCH and PUSCH DMRS scheduled by the DCI, the terminal determines the SRS associated with the second uplink signal based on the SRS that adopts a same beam as the second uplink signal. Herein, the network device may configure the SRS resource for the SRS that adopts a same beam as the second uplink signal and a PTRS port corresponding to each SRS resource in advance through high-layer signaling. The second uplink signal may be any one of the two uplink signals. 
     In a third implementation mode, when the reference signals respectively associated with the two uplink signals are CSI-RSs, the reference signals respectively associated with the two uplink signals to be transmitted meeting the preset condition may include that: CSI-RS resources for the CSI-RSs respectively associated with the two uplink signals belong to different CSI-RS resource sets. 
     As an implementation mode, when the CSI-RS resources for the CSI-RSs respectively associated with the two uplink signals belong to different SRS resource sets, in this application scenario, the terminal may consider that the two uplink signals are needed to be transmitted through different panels. In such case, if the network device configures the two uplink signals to be transmitted on the same time-domain resource, the terminal may simultaneously send the two uplink signals through different panels. 
     In the implementation mode, the method may further include that: when the CSI-RS resources for the CSI-RSs respectively associated with the two uplink signals belong to the same CSI-RS resource set, the terminal sends the uplink signal with the higher priority in the at least two uplink signals, or, the terminal does send neither of the two uplink signals. 
     As an example, when the CSI-RS resources for the CSI-RSs respectively associated with the two uplink signals belong to the same CSI-RS resource set, the terminal may consider that the two uplink signals can be transmitted through the same panel only, and in such case, the terminal cannot simultaneously send the two uplink signals. If the network device configures the two uplink signals to be transmitted on the same time-domain resource, as an example, the terminal may determine the uplink signal with the higher priority from the two uplink signals according to the preset priority rule and only send the uplink signal with the higher priority; and as another example, the terminal does send neither of the two uplink signals. For the second application scenario, if the network device configures the two uplink signals to be simultaneously transmitted, the terminal may process the present case as an error case and is not needed to send the two uplink signals according to the configuration of the network device. 
     In the implementation mode, the terminal may obtain a CSI-RS resource for a CSI-RS associated with an uplink signal from spatial relation information configured by the network device for the uplink signal. 
     In a fourth implementation mode, when the reference signals respectively associated with the two uplink signals are SSBs, the reference signals respectively associated with the two uplink signals to be transmitted meeting the preset condition may include that: the SSBs respectively associated with the two uplink signals include different cell information. 
     As an implementation mode, when the SSBs respectively associated with the two uplink signals include different cell information, in this application scenario, the terminal may consider that the two uplink signals are needed to be transmitted through different panels. In such case, if the network device configures the two uplink signals to be transmitted on the same time-domain resource, the terminal may simultaneously send the two uplink signals through different panels. Herein, the cell information may include a cell Identifier (ID) or public system information of a cell. 
     In the implementation mode, the method may further include that: when the SSBs respectively associated with the two uplink signals include the same cell information, the terminal sends the uplink signal with a higher priority in the two uplink signals, or, the terminal does send neither of the two uplink signals. 
     When the SSBs respectively associated with the two uplink signals include the same cell information, the terminal may consider that the two uplink signals can be transmitted through the same panel only, and in such case, the terminal cannot simultaneously send the two uplink signals. If the network device configures the two uplink signals to be transmitted on the same time-domain resource, as an example, the terminal may determines the uplink signal with the higher priority from the two uplink signals according to the preset priority rule and only send the uplink signal with the higher priority; and as another example, the terminal does send neither of the two uplink signals. For the second application scenario, if the network device configures the two uplink signals to be simultaneously transmitted, the terminal may process the present case as an error case and is not needed to send the two uplink signals according to the configuration of the network device. 
     In the implementation mode, the terminal may obtain an SSB associated with an uplink signal from spatial relation information configured by the network device for the uplink signal. 
     It can be seen from the abovementioned implementation modes that the operation that the terminal receives the associated reference signals configured by the network device respectively for the two uplink signals to be transmitted may include that: the terminal determines each reference signal respectively associated with each of at least one uplink signal according to spatial relation information configured by the network device for the at least one uplink signal of the two uplink signals to be transmitted. 
     In an implementation mode of the disclosure, the operation that the terminal receives the associated reference signals configured by the network device respectively for the two uplink signals to be transmitted may include that: the terminal receives the associated reference signals configured by the network device respectively for the two uplink signals to be transmitted based on Radio Resource Control (RRC) signaling, Media Access Control (MAC) signaling or DCI. 
     As a first implementation mode, the operation that the terminal receives the associated reference signals configured by the network device respectively for the two uplink signals to be transmitted based on the RRC signaling, the MAC signaling or the DCI may include that: when a third uplink signal of the two uplink signals is a periodic signal, the terminal receives the associated reference signal configured by the network device for the third uplink signal based on the RRC signaling. 
     As a second implementation mode, the operation that the terminal receives the associated reference signals configured by the network device respectively for the two uplink signals to be transmitted based on the RRC signaling, the MAC signaling or the DCI may include that: when a fourth uplink signal of the two uplink signals is a quasi-persistent signal, the terminal receives the associated reference signal configured by the network device for the fourth uplink signal based on the MAC signaling. 
     As a third implementation mode, the operation that the terminal receives the associated reference signals configured by the network device respectively for the two uplink signals to be transmitted based on the RRC signaling, the MAC signaling or the DCI may include that: when a fifth uplink signal of the two uplink signals is an aperiodic signal, the terminal receives the associated reference signal configured by the network device for the fifth uplink signal based on the DCI. 
     In an implementation mode of the disclosure, the operation that the two uplink signals are simultaneously sent may include that: the terminal simultaneously sends the two uplink signals through different panels. During a practical application, the terminal may adopt independent beams to send the two uplink signals respectively. 
     With adoption of the technical solution of the embodiments of the disclosure, a terminal may determine based on reference signals respectively associated with two uplink signals to be transmitted that the two uplink signals may be simultaneously transmitted through different panels, so that the terminal can simultaneously send two different types of uplink signals (or multiple different types of uplink signals), thereby avoiding increase of a peak-to-average ratio and guaranteeing higher transmission performance.

     In the implementation mode, the communication unit  31  is further configured to, when ports of the uplink PTRSs respectively associated with the two uplink signals are the same, send an uplink signal with a higher priority in the two uplink signals or send neither of the two uplink signals.
