Device and method for controlling idle mode discontinuous reception

Abstract:

The present disclosure relates to a wireless device and a method, for use in a wireless device, for controlling discontinuous reception, DRX, during idle mode. The method comprises selecting (S31) a default DRX cycle pattern for controlling operative instants during a DRX cycle and receiving (S32) from an access node, a first set of beams in the operative instants of the default DRX cycle pattern. The method further comprises determining (S33) reception quality metrics for respective beams and determining (S34), based on the reception quality metrics, a customized DRX cycle pattern for controlling operative instants during a subsequent DRX cycle. The customized DRX cycle pattern is applied (S35) in the subsequent DRX cycle to receive a second set of beams.
