Abstract: Methods and apparatuses for beam measurement and reporting. A method performed by a user equipment (UE) includes transmitting capability information; receiving information indicating a group based beam reporting; and measuring reference signals. The method further includes determining, based on the information and the measurement, a group of two resource indicators; determining, based on the measurement, beam metrics corresponding to the group of two resource indicators; and transmitting, in a channel state information (CSI) reporting instance, the group of two resource indicators and the beam metrics. A resource indicator in the group of two resource indicators is one of: (1) a synchronization signal/physical broadcast channel (PBCH) block (SSB) resource indicator (SSBRI) and (2) a CSI reference signal (CSI-RS) resource indicator (CRI). A beam metric in the beam metrics is one of: (1) a layer-1 reference signal received power (L1-RSRP) and (2) a layer-1 signal to interference and noise ratio (L1-SINR).
