Abstract
Embodiments of the present disclosure are related to achieving better tradeoffs between battery saving and latency to, e.g., support ultra-low latency applications by introducing soft Discontinuous Reception (DRX). In some embodiments, a method of operation of a wireless device in a wireless communications network comprises monitoring, during a DRX awake period, two or more control channel subsets during two or more time periods within the DRX awake period, respectively. The two or more control channel subsets are different subsets of a plurality of candidate control channels. In some embodiments, the two or more time periods are two or more subframes. The candidate control channels are control channels that the wireless device is configured to monitor. The two or more control channel subsets can be selected to, e.g., reduce latency while not increasing energy consumption as compared to legacy DRX.
