Abstract
An operating method of a user equipment (UE) to save power of the UE in a wireless communication system is provided. The operating method includes receiving wake up signal (WUS) configuration information from a base station (BS), monitoring a physical downlink control channel (PDCCH) based on the WUS configuration information, and stopping monitoring the PDCCH based on the WUS configuration information and operating in a short discontinuous reception (DRX) cycle, when a certain event occurs in Active time.
Claims12
A method performed by a user equipment (UE) in a wireless communication system, the method comprising:
- receiving, from a base station, a radio resource control (RRC) message including configuration information for monitoring power saving information;
- in case that a long discontinuous reception (DRX) cycle is used and a subframe where the long DRX cycle starts is determined, identifying whether power saving information monitoring is configured;
- in case that the power saving information monitoring is configured, monitoring a physical downlink control channel (PDDCH) for detection of the power saving information, based on the configuration information;
- and
- in case that the power saving information is not detected, starting a drx-onDurationTimer.
A user equipment (UE) in a wireless communication system, the UE comprising:
- a transceiver;
- and
- at least one processor coupled to the transceiver and configured to:
- receive, from a base station, a radio resource control (RRC) message including configuration information for monitoring power saving information;
- in case that a long discontinuous reception (DRX) cycle is used and a subframe where the long DRX cycle starts is determined, identify whether power saving information monitoring is configured;
- in case that the power saving information monitoring is configured, monitor a physical downlink control channel (PDDCH) for detection of the power saving information, based on the configuration information;
- and
- in case that the power saving information is not detected, start a drx-onDurationTimer.
