Transmission of layer 1 reference signal received power in channel state information during a discontinuous operation
A wireless device may receive a report mask indicating channel state information (CSI) reporting, comprising a layer 1 reference signal received power (L1-RSRP) value, is limited to a discontinuous reception (DRX) on duration of a DRX cycle. The wireless device may based on the report mask, transmit at a first time a first CSI report, comprising a first L1-RSRP value, in response to a DRX timer, associated with the DRX on duration, running at a time interval before the first time. The wireless device may based on the report mask, skip at a second time a transmission of a second CSI report, comprising a second L1-RSRP value, in response to the DRX timer not running at the time interval before the second time.
