Abstract

A wireless device receives message(s) comprising: a first value for an uplink hybrid automatic repeat request (HARQ) round-trip-time (RTT) timer; and a second value for an uplink discontinuous reception (DRX) retransmission timer. A transport block is transmitted via an uplink data channel. The uplink HARQ RTT timer is started with the first value in response to transmitting the transport block. The first value indicates a first number of symbols. The uplink DRX retransmission timer is started with the second value in response to the uplink HARQ RTT timer expiring. The second value indicates of a second number of slot lengths. A downlink control channel is monitored while the uplink DRX retransmission timer is running.

Claims20

Dependent claims

A method comprising:

receiving, by a wireless device, one or more radio resource control 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;
transmitting a transport block via an uplink data channel;
starting an uplink HARQ RTT timer with the uplink HARQ RTT timer value in response to transmitting the transport block, wherein the uplink HARQ RTT timer value indicates a first number of symbols;
starting an uplink DRX retransmission timer with the uplink DRX retransmission timer value in response to the uplink HARQ RTT timer expiring, wherein the uplink DRX retransmission timer value indicates a second number of slot lengths;
and
monitoring a downlink control channel while the uplink DRX retransmission timer is running.
