1. A method implemented in a wireless device (WD) a control channel during discontinuous reception, DRX, cycle periods, each DRX cycle period comprising an on-duration and an off-duration;
setting a set of short DRX cycle periods for short DRX cycles;
setting an initial long DRX cycle value for long DRX cycles, the initial long DRX cycle value being longer than the set of short DRX cycle periods;
monitoring the control channel during the on-duration of one or more DRX cycles having a first short DRX cycle value selected from the set of short DRX cycle periods;
if no control message is received using the first short DRX cycle value, monitoring the control channel during the on-durations of one or more DRX cycles having a second short DRX cycle value selected from the set of short DRX cycle periods, the second short DRX cycle value being longer than the first short DRX cycle value; and
if no control message is received using the second short DRX cycle value, monitoring the control channel during the on-duration of one or more DRX cycles having the initial long DRX cycle value.
