Abstract:
Systems, devices, and methods for low-overhead and low latency multi-beam operation in an advanced wireless communication system. A method of a user equipment (UE) for a multi-beam operation in a wireless communication system includes: receiving, from a base station (BS), a sounding reference signal (SRS) resource configuration; receiving, from the BS, a triggering message instructing the UE to transmit an SRS; receiving, from the BS, a configuration for a transmission configuration indicator (TCI) state that includes an identification (ID) indicating the SRS resource configuration; identifying a set of resources to transmit the SRS; and transmitting, to the BS over an uplink channel, the SRS based on the SRS resource configuration with a spatial domain transmission filter. The UE receives a downlink transmission from the BS with a spatial domain receive filter that is determined according to the ID included in the TCI state that is indicated for the downlink transmission.
