HYBRID SPATIAL DOMAIN AND FREQUENCY DOMAIN BASIS SELECTION FOR COHERENT JOINT TRANSMISSION FEEDBACK

Title:

HYBRID SPATIAL DOMAIN AND FREQUENCY DOMAIN BASIS SELECTION FOR COHERENT JOINT TRANSMISSION FEEDBACK

Document Type and Number:

WIPO Patent Application WO/2023/216049

Kind Code:

A1

Abstract:

Certain aspects of the present disclosure provide a method of wireless communication by a user equipment (UE). The method generally includes receiving configuration information indicating resources associated with one or more subsets of transmission reception points (TRPs), wherein TRPs of a given subset share at least one of:a spatial domain (SD) basis selection, a frequency domain (FD) basis selection, or a delay window for FD basis selection, measuring channel state information (CSI) reference signals (CSI-RSs) from the one or more subsets of TRPs, transmitting a CSI report indicating at least one of the one or more subsets of TRPs in accordance with the configuration information.
