A base station transmits one or more radio resource control messages to a wireless device. The base station receives from the wireless device, a transport block via an uplink data channel. The one or more radio resource control messages include: a HARQ RTT timer value indicating the wireless device to start an uplink HARQ RTT timer with the uplink HARQ RTT timer value in response to transmitting the transport block to the base station, a DRX retransmission timer value indicating the wireless device to start an uplink DRX retransmission timer with the uplink DRX retransmission timer value in response to transmitting the transport block. The uplink DRX retransmission timer is for UE to monitor a downlink control channel while the uplink DRX retransmission timer is running.
