1. A method implemented at a wireless device configured with a connected discontinuous reception, C-DRX, configuration defining an active mode and a non-active mode, the active mode defining a plurality of on-durations, the non-active mode defining at least one off-duration, the method comprising:
receiving an assignment signal comprising an assignment configuration, the assignment configuration comprising an assignment of at least one control resource set, CORESET, to the wireless device, the at least one CORSET being associated with at least one search space for the wireless device to monitor for a first power saving signal and a second power saving signal, the first power saving signal to be received by the wireless device outside one on-duration of the plurality of on-durations, the second power saving signal to be received by the wireless device within or outside one on-duration of plurality of on-durations;
receiving the first power saving signal and the second power saving signal based at least in part on the assignment configuration, the first power saving signal being received before a first on-duration of the plurality of durations, the second power saving signal being subsequent to the first-on duration; and
operating the wireless device in the active mode in response to receiving the first power saving signal and in the non-active mode in response to receiving the second power saving signal.
