Abstract:
Configuration parameters, of channel state information (CSI) resources for a first transmission reception point (TRP) and a second TRP of a cell, are received. One or more media access control control elements (MAC CEs) are received. The MAC CEs indicate a first semi persistent CSI report for the first TRP. The MAC CEs indicate a second semi persistent CSI report for the second TRP. First reference signal received power (RSRP) values, for the first semi persistent CSI report, are determined based on the plurality of CSI resources. Second RSRP values, for the second semi persistent CSI report, are determined based on the CSI resources. A codeword, comprising the first RSRP values and the second RSRP values, is created. The codeword is transmitted, based on the first semi persistent CSI report and the second semi persistent CSI report, via a physical uplink control channel resource.
