Abstract: A method of a user equipment (UE) in a wireless communication system is provided. The method comprises receiving, from at least one transmission and reception point (TRP) of a group of (N) TRPs, channel status information (CSI) configuration information, determining a CSI report based on the CSI configuration information, identifying, based on the configuration information, one or more TRPs of the group of (N) TRPs to transmit the determined CSI report, and transmitting, to the one or more TRPs, the determined CSI report over an uplink channel. The determined CSI report includes a TRP indicator for selecting (M) TRPs of the group of (N) TRPs, and CSI for each of the selected (M) TRPs, wherein N is greater than one, and wherein M is greater or equal to 1, and less or equal to N.

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.
