Abstract
A method by which a terminal monitors a control channel in a wireless communication system, and a device using the method are provided. The method determines whether physical downlink control channel (PDCCH) monitoring occasions overlap in a plurality of control resource sets (CORESETs), selects at least one CORESET from among the plurality of CORESETs when the PDCCH monitoring occasions overlap, and monitors a PDCCH only in the selected at least one CORESET from among the plurality of CORESETs.
Claims10
A method of monitoring a control channel of a user equipment (UE) in a wireless communication system, the method comprising:
- based on physical downlink control channel (PDCCH) monitoring occasions being overlapped in a plurality of control resource sets (CORESETs) having different spatial quasi co-location (QCL) properties, selecting one CORESET from the plurality of CORESETs;
- and
- monitoring PDCCH candidates only in the one CORESET selected from the plurality of CORESETs,
- wherein the one CORESET is selected based on a type of a related search space,
- wherein the type of the search space is a common search space (CSS) or a UE-specific search space (USS),
- wherein selecting the one CORESET comprises:
- selecting a CORESET that comprises a CSS having a lowest index, based on a plurality of CORESETs comprising a CSS.
A user equipment (UE), comprising:
- a transceiver configured to transmit and receive wireless signals;
- and
- a processor configured to operate in combination with the transceiver,
- wherein the processor is further configured to:
- based on physical downlink control channel (PDCCH) monitoring occasions being overlapped in a plurality of control resource sets (CORESETs) having different spatial quasi co-location (QCL) properties, select one CORESET from the plurality of CORESETs;
- and
- monitor PDCCH candidates only in the one CORESET selected from the plurality of CORESETs,
- wherein the one CORESET is selected based on a type of a related search space, and
- wherein the type of the search space is a common search space (CSS) or a UE-specific search space (USS),
- wherein selecting the one CORESET comprises:
- selecting a CORESET that comprises a CSS having a lowest index, based on a plurality of CORESETs comprising a CSS.
A processor for controlling a wireless communication device in a wireless communication system, wherein the processor is configured to control the wireless communication device to:
- based on physical downlink control channel (PDCCH) monitoring occasions being overlapped in a plurality of control resource sets (CORESETs) having different spatial quasi co-location (QCL) properties, select one CORESET from the plurality of CORESETs;
- and
- monitor PDCCH candidates only in the one CORESET selected from the plurality of CORESETs,
- wherein the one CORESET is selected based on a type of a related search space, and
- wherein the type of the search space is a common search space (CSS) or a UE-specific search space (USS),
- wherein selecting the one CORESET comprises:
- selecting a CORESET that comprises a CSS having a lowest index, based on a plurality of CORESETs comprising a CSS.
