Abstract
Provided are a method by which a terminal monitors a downlink control channel in a wireless communication system and a corresponding device. An offset-based time window is set before a conventional DRX-on period for monitoring PDCCH, and PSPDCCH for notifying of power saving information in the time window is monitored. Whether to actually monitor the PDCCH in the DRX-on period can be determined on the basis of the PS-PDCCH.
Claims18
A method of monitoring a physical downlink control channel (PDCCH) of a user equipment (UE) in a wireless communication system, the method comprising:
- receiving a configuration related to a plurality of PDCCH monitoring occasions;
- receiving an offset based on a starting slot of a discontinuous reception (DRX)-on duration;
- and
- monitoring a PS-PDCCH notifying of power saving (PS) information in at least one PDCCH monitoring occasion among the plurality of PDCCH monitoring occasions,
- wherein the PS-PDCCH is not monitored in the DRX-on duration, and
- wherein the PS-PDCCH is monitored in the at least one PDCCH monitoring occasion located in a time window between a time based on the offset and the starting slot of the DRX-on duration.
A user equipment (UE) comprising:
- a transceiver transmitting and receiving a radio signal;
- and
- a processor operatively coupled with the transceiver,
- wherein the processor is configured to:
- receive a configuration related to a plurality of PDCCH monitoring occasions,
- receive an offset based on a starting slot of a discontinuous reception (DRX)-on duration, and
- monitor a PS-PDCCH notifying of power saving (PS) information in at least one PDCCH monitoring occasion among the plurality of PDCCH monitoring occasions,
- wherein the PS-PDCCH is not monitored in the DRX-on duration, and
- wherein the PS-PDCCH is monitored in the at least one PDCCH monitoring occasion located in a time window between a time based on the offset and the starting slot of the DRX-on duration.
A method of transmitting a physical downlink control channel (PDCCH) of a base station (BS) in a wireless communication system, the method comprising:
- transmitting a configuration related to a plurality of PDCCH monitoring occasions;
- transmitting an offset based on a starting slot of a discontinuous reception (DRX)-on duration;
- and
- transmitting a PS-PDCCH notifying of power saving (PS) information in at least one physical downlink control (PDCCH) monitoring occasion among the plurality of PDCCH monitoring occasions,
- wherein the PS-PDCCH is not transmitted in the DRX-on duration, and
- wherein the PS-PDCCH is transmitted in the at least one PDCCH monitoring occasion located in a time window between a time based on the offset and the starting slot of the DRX-on duration.
An apparatus of a wireless communication system, the apparatus comprising:
- a processor;
- and
- a memory operatively coupled with the processor,
- the processor is configured to:
- receive a configuration related to a plurality of PDCCH monitoring occasions,
- receive an offset based on a starting slot of a discontinuous reception (DRX)-on duration;
- and
- monitor a PS-PDCCH notifying of power saving (PS) information in at least one physical downlink control (PDCCH) monitoring occasion among the plurality of PDCCH monitoring occasions,
- wherein the PS-PDCCH is not monitored in the DRX-on duration, and
- wherein the PS-PDCCH is monitored in the at least one PDCCH monitoring occasion located in a time window between a time based on the offset and the starting slot of the DRX-on duration.
