Title:

BEAM MANAGEMENT ENHANCEMENTS FOR MULTI-TRP SCENARIOS

Document Type and Number:

WIPO Patent Application WO/2020/239010

Kind Code:

A1

Abstract:

Apparatus, methods, processing systems, and computer readable mediums for beam management in multi-TRP scenarios are disclosed. An exemplary method generally includes receiving a channel state information reference signal (CSI-RS) resource configuration from at least one base station (BS) for one or more transmission hypotheses, wherein the CSI-RS resource configuration includes CSI-RS resources corresponding to at least a first downlink (DL) demodulation reference signal (DMRS) -port-group and a second DL DMRS-port-group, performing one or more CSI-RS measurements for the one or more transmission hypotheses based, at least in part on the CSI-RS resource configuration, and determining, for each of the one or more transmission hypotheses, a preferred reception beam for communicating with the at least one BS based, at least in part, on the one or more CSI-RS measurements.
