Priority of channel state information report
A wireless device determines a priority value of a first channel state information (CSI) report, using: a first parameter having a value of zero based on the first CSI report being initiated by the wireless device; a second parameter, associated with a report quantity of the first CSI report, having a value of zero based on the first CSI report comprising a predicted layer 1 reference signal received power (L1-RSRP); a third parameter that is an index of a serving cell; and a fourth parameter that is a configuration identifier of the first CSI report. The wireless device transmits the first CSI report based on: the priority value being smaller than a second priority value of a second CSI report; and a transmission, via a first resource, of the first CSI report overlapping in time with a transmission, via a second resource, of the second CSI report.
