1. A method comprising:
receiving, by a wireless device from a base station, configuration parameters indicating:
channel state information (CSI) resources for a cell; and
a periodicity of semi persistent (SP) CSI reports, wherein the periodicity corresponds to a plurality of transmission and reception points (TRPs);
receiving an SP CSI report activation media access control control element (MAC CE) indicating the SP CSI reports; and
transmitting, to the base station in response to the SP CSI report activation MAC CE and based on the periodicity of the SP CSI reports, a codeword comprising reference signal received power (RSRP) values for the SP CSI reports determined based on the CSI resources.
