Abstract:
A technique for power saving, comprising establishing a radio resource control (RRC) connection with a wireless system, entering an RRC connected mode based on the established RRC connection, receiving, from the wireless system, configuration information indicating a discontinuous reception (DRX) cycle time, a DRX on time period, and an offset time, determining an enhanced wake-up signal (EWUS) monitoring occasion for a DRX cycle based on the offset time and the DRX on time period, monitoring, during a first DRX cycle, for an EWUS during the EWUS monitoring occasion associated with the first DRX cycle, receiving, from the wireless system, the EWUS during the EWUS monitoring occasion, determining that the EWUS indicates that the wireless device skip one or more future EWUS monitoring occasions, and skipping monitoring for the EWUS based on the indicated skipped one or more future EWUS monitoring occasions.
