Abstract:
Aspects relate to beam management in multi-stream communication between a radio access network (RAN) entity and a user equipment (UE). The RAN entity may transmit a plurality of transmit beams from a plurality of transmission and reception points (TRPs) associated with the RAN entity to the UE. For each of the transmit beams, the UE may obtain a beam quality metric on each of a plurality of receive beams of the UE during a measurement period (e.g., in parallel or serially) to generate a respective beam quality metric vector for each of the transmit beams. The UE can then transmit a beam report including the respective beam quality metric vector for each of the transmit beams to the RAN entity. The RAN entity may then select at least two beam pair links, each associated with a respective TRP, for spatial division multiplexing of at least two streams to the UE based on the beam report.
