Abstract

Disclosed are an transmission indication method and apparatus, a terminal, a base station and a storage medium. The transmission indication method is applied to a terminal and includes: receiving, from a base station, a Radio Resource Control (RRC) signaling comprising a path loss (PL) reference signal (RS) resource pool, the PL RS resource pool comprising at least one PL RS resource; receiving, from the base station, a control signaling comprising an indicator indicating a PL RS resource selected from the PL RS resource pool; and transmitting an uplink reference signal based on the PL RS resource selected from the PL RS resource pool.

What is claimed is: 
     
         1 . A transmission indication method, applied to a terminal, comprising:
 receiving, from a base station, a Radio Resource Control (RRC) signaling comprising a path loss (PL) reference signal (RS) resource pool, the PL RS resource pool comprising at least one PL RS resource;   receiving, from the base station, a control signaling comprising an indicator indicating a PL RS resource selected from the PL RS resource pool; and   transmitting an uplink reference signal based on the PL RS resource selected from the PL RS resource pool.   
     
     
         2 . The method of  claim 1 , further comprising:
 associating the PL RS resource selected from the PL RS resource pool with a Sounding Reference Signal (SRS) resource set.   
     
     
         3 . The method of  claim 1 , wherein the uplink reference signal is used for beam management, a codebook mode, a non-codebook mode, or antenna switching. 
     
     
         4 . The method of  claim 1 , wherein the control signaling comprises a media access control-control element (MAC-CE) signaling. 
     
     
         5 . The method of  claim 1 , wherein the uplink reference signal comprises a channel sounding reference signal. 
     
     
         6 . A device comprising a memory for storing computer instructions and a processor in communication with the memory, wherein, when the processor executes the computer instructions, the processor is configured to cause the device to:
 receive, from a base station, an RRC signaling comprising a PL RS resource pool, the PL RS resource pool comprising at least one PL RS resource;   receive, from the base station, a control signaling comprising an indicator indicating a PL RS resource selected from the PL RS resource pool; and   transmit an uplink reference signal based on the PL RS resource selected from the PL RS resource pool.   
     
     
         7 . The device of  claim 6 , wherein, when the processor executes the computer instructions, the processor is configured to further cause the device to:
 associate the PL RS resource selected from the PL RS resource pool with an SRS resource set.   
     
     
         8 . The device of  claim 6 , wherein the uplink reference signal is used for beam management, a codebook mode, a non-codebook mode, or antenna switching. 
     
     
         9 . The device of  claim 6 , wherein the control signaling comprises a MAC-CE signaling. 
     
     
         10 . The device of  claim 6 , wherein the uplink reference signal comprises a channel sounding reference signal. 
     
     
         11 . A transmission indication method, applied to a base station, comprising:
 transmitting, to a User Equipment (UE), an RRC signaling comprising a PL RS resource pool, the PL RS resource pool comprising at least one PL RS resource;   transmitting, to the UE, a control signaling comprising an indicator indicating a PL RS resource selected from the PL RS resource pool; and   receiving an uplink reference signal, the uplink reference signal being based on the PL RS resource selected from the PL RS resource pool.   
     
     
         12 . The method of  claim 11 , wherein the uplink reference signal is used for beam management, a codebook mode, a non-codebook mode, or antenna switching. 
     
     
         13 . The method of  claim 11 , wherein the control signaling comprises a MAC-CE signaling. 
     
     
         14 . The method of  claim 11 , wherein the uplink reference signal comprises a channel sounding reference signal. 
     
     
         15 . A device comprising a memory for storing computer instructions and a processor in communication with the memory, wherein, when the processor executes the computer instructions, the processor is configured to cause the device to:
 transmit, to a User Equipment (UE), an RRC signaling comprising a PL RS resource pool, the PL RS resource pool comprising at least one PL RS resource;   transmit, to the UE, a control signaling comprising an indicator indicating a PL RS resource selected from the PL RS resource pool; and   receive an uplink reference signal, the uplink reference signal being based on the PL RS resource selected from the PL RS resource pool.   
     
     
         16 . The device of  claim 15 , wherein the uplink reference signal is used for beam management, a codebook mode, a non-codebook mode, or antenna switching. 
     
     
         17 . The device of  claim 15 , wherein the control signaling comprises a MAC-CE signaling. 
     
     
         18 . The device of  claim 15 , wherein the uplink reference signal comprises a channel sounding reference signal. 
     
     
         19 . A computer program product comprising a non-transitory computer-readable program medium with computer code stored thereupon, the computer code, when executed by one or more processors, causing the one or more processors to implement a method of  claim 1 .
