Abstract
A method by which a terminal monitors a physical downlink control channel (PDCCH) in a wireless communication system, and a device therefor are provided. In the method, a terminal wakes up in a DRX cycle linked with a monitoring occasion so as to monitor a PDCCH if a wake up signal (WUS) monitoring occasion does not exist in a monitoring window for allowing the terminal to monitor the WUS.
Claims15
A method of operating a user equipment (UE) in a wireless communication system, the method comprising:
- receiving a configuration message informing of monitoring occasions for detection of downlink control information (DCI) formats, wherein the DCI formats comprise a DCI format 2_6 including a wake-up indication;
- based on at least one of the monitoring occasions being located within a time duration from a time indicated by an offset, where the UE starts monitoring a first physical downlink control channel (PDCCH) for detection of the DCI format 2_6, prior to a slot where a next discontinuous reception (DRX)-on duration timer would start, monitoring a second PDCCH for detection of a DCI format other than the DCI format 2_6 in a next DRX-on duration depending on a value for the wake-up indication of the DCI format 2_6 detected in the at least one of the monitoring occasions;
- and
- based on the monitoring occasions not being located within the time duration, monitoring the second PDCCH for detection of the DCI format other than the DCI format 2_6 in the next DRX-on duration.

A user equipment (UE), comprising:
- a transceiver;
- and
- a processor being operatively connected to the transceiver,
- wherein the processor is configured to:
- receive a configuration message informing of monitoring occasions for detection of downlink control information (DCI) formats, wherein the DCI formats comprises a DCI format 2_6 including a wake-up indication,
- based on at least one of the monitoring occasions being located within a time duration from a time indicated by an offset, where the UE starts monitoring a first physical downlink control channel (PDCCH) for detection of the DCI format 2_6, prior to a slot where a next discontinuous reception (DRX)-on duration timer would start, monitor a second PDCCH for detection of a DCI format other than the DCI format 2_6 in a next DRX-on duration depending on a value for the wake-up indication of the DCI format 2_6 detected in the at least one of the monitoring occasions, and
- based on the monitoring occasions not being located within the time duration, monitor the second PDCCH for detection of the DCI format other than the DCI format 2_6 in the next DRX-on duration.

An apparatus operating in a wireless communication system, comprising:
- a processor;
- and
- a memory coupled with the processor,
- wherein the processor is configured to:
- receive a configuration message informing of monitoring occasions for detection of downlink control information (DCI) formats, wherein the DCI formats comprises a DCI format 2_6 including a wake-up indication;
- based on at least one of the monitoring occasions being located within a time duration from a time indicated by an offset, where the apparatus starts monitoring a first physical downlink control channel (PDCCH) for detection of the DCI format 2_6, prior to a slot where a next discontinuous reception (DRX)-on duration timer would start, monitor a second PDCCH for detection of a DCI format other than the DCI format 2_6 in a next DRX-on duration depending on a value for the wake-up indication of the DCI format 2_6 in the at least one of the monitoring;
- and
- based on the monitoring occasions not being located within the time duration, monitor the second PDCCH for detection of the DCI format other than the DCI format 2_6 in the next DRX-on duration.
