Abstract
Methods and apparatuses for joint channel state information (CSI) measurement are described herein. A method may include receiving channel state information reference signals (CSI-RSs) from first and second transmit/receive points (TRPs), determining CSI, and selecting one of the TRPs as a primary TRP and a remaining one of the first TRP or the second TRP as a secondary TRP. The method may include reporting information indicating a first CSI for the primary TRP and receiving second CSI-RSs from the TRPs. The method may include determining a second CSI and a precoding matrix indicator (PMI) for the primary TRP, and determining channel coding information for the primary TRP. The method may include determining a second CSI for the secondary TRP, determining, based on channel coding information and the second CSI for the secondary TRP and a PMI for the secondary TRP, and reporting information indicating the PMI for the second TRP.
