1. A method comprising:
transmitting, by a base station to a wireless device, one or more radio resource control messages; and
transmitting, by the base station, downlink control information indicating downlink transmission of a transport block via a downlink data channel;
wherein the one or more radio resource control messages comprise a downlink hybrid automatic repeat request (HARQ) round-trip-time (RTT) timer value expressed in units of symbols indicating the wireless device to start a downlink HARQ RTT timer with the downlink HARQ RTT timer value in response to receiving the downlink control information; and
a downlink discontinuous reception (DRX) retransmission timer value expressed in units of slot lengths indicating the wireless device to start a downlink DRX retransmission timer with the downlink DRX retransmission timer value in response to the downlink HARQ RTT timer expiring and the transport block not being successfully decoded, wherein the downlink DRX retransmission timer is for the wireless device to monitor a downlink control channel while the downlink DRX retransmission timer is running;
wherein the downlink HARQ RTT timer value indicates a first number of symbols;
wherein the downlink DRX retransmission timer value indicates a second number of slot lengths.
