Discontinuous reception inactivity timer and a semi-persistent channel state information of aa wireless device
A wireless device receives: a value for a discontinuous reception (DRX) inactivity timer; and a semi-persistent channel state information (SP-CSI) radio network temporary identifier (RNTI). receive a first downlink control information (DCI) corresponding to the SP-CSI RNTI is received. The SP-CSI RNTI indicates: activation of SP-CSI reporting; and no uplink grant for uplink packet transmission. The DRX inactivity timer is started based on the first DCI indicating the activation of the SP-CSI reporting. The DRX inactivity timer controls monitoring for DCIs of the SP-CSI RNTI. a transport block is transmitted based on receiving, while the DRX inactivity timer is running, a second DCI.
