RANDOM ACCESS CHANNEL PROCEDURE FOR MULTIPLE TRANSMIT-RECEIVE POINTS

Abstract:

Methods, systems, and devices for wireless communication are described. A device, such as a user equipment (UE) may receive a set of synchronization signal blocks (SSBs) from multiple transmit-receive points (mTRPs). The set of SSB may include a first subset of SSBs associated with a first TRP and a second subset of SSBs associated with a second TRP. Each SSB may correspond to a respective directional beam (e.g., a transmit beam, a receive beam). The UE may transmit, to a base station, an indication of a selected first SSB from the first subset of SSBs associated with the first TRP and a selected second SSB from the second subset of SSBs associated with the second TRP. The UE may perform a random access channel procedure with the base station, the first TRP, the second TRP, or a combination thereof based on the transmitted indication.
