Wireless device control channel monitoring
A wireless device comprises one or more processors and memory storing instructions, When executed by the one or more processors, the instructions cause the wireless device to receive one or more messages comprising an uplink hybrid automatic repeat request (HARQ) round-trip-time (RTT) timer value expressed in units of symbols and an uplink discontinuous reception (DRX) retransmission timer value expressed in units of slot lengths, transmit a transport block via an uplink data channel, start an uplink HARQ RTT timer with the uplink HARQ RTT timer value in response to transmitting the transport block, start an uplink DRX retransmission timer with the uplink DRX retransmission timer value in response to the uplink HARQ RTT timer expiring, monitor a downlink control channel while the uplink DRX retransmission timer is running.
