A METHOD TO DETERMINE SPATIAL QUASI CO-LOCATION (QCL) ASSUMPTION FOR CHANNEL STATE INFORMATION REFERENCE SIGNAL (CSI-RS) IN NEW RADIO (NR)

Abstract:

An apparatus configured to be employed in a user equipment (UE) associated with a new radio (NR) communication system is disclosed. The apparatus comprises one or more processors configured to process a physical downlink shared channel (PDSCH) scheduling signal, received from a gNodeB associated therewith, wherein the PDSCH scheduling signal is configured to schedule a transmission of PDSCH. In some embodiments, the PDSCH scheduling signal comprises a transmission configuration indicator (TCI) state indicative of a channel state information reference signal (CSI-RS) resource that is triggered aperiodically. In some embodiments, the apparatus is further configured to determine a receive (Rx) beam to be utilized for the reception of the scheduled PDSCH transmission, that forms a PDSCH Rx beam, based on the indicated CSI-RS resource.
