Abstract:
In some implementations, a power saving method includes receiving, from a base station, at a user equipment (UE), a Discontinuous Reception (DRX) configuration. The UE determines a WLAN listen interval that includes at least one Traffic Indication Map (TIM) period and at least one TIM transmission period. The UE selects, based on the DRX configuration, a TIM message to monitor within an associated TIM transmission period from the at least one TIM transmission period in the listen interval. The UE determines a WLAN wakeup time that overlaps the associated TIM transmission period. During the associated TIM transmission periods, the UE receives, from an Access Point (AP), the selected TIM message.
