A wireless device receives DRX configuration parameters comprising a first parameter indicating a first value of a downlink DRX retransmission timer. In response to receiving a first TB, the wireless device may start the downlink DRX retransmission timer with the first value. The wireless device may switch a downlink control channel monitoring periodicity from a first monitoring periodicity to a second monitoring periodicity based on receiving first control information. In response to receiving a second TB and based on the switching the downlink control channel monitoring periodicity, the wireless device may start the downlink DRX retransmission timer with a second value. The wireless device may receive, while the downlink DRX retransmission timer is running, a downlink control information comprising a downlink assignment for retransmission of the second TB.
