Abstract
Disclosed is a base station of a wireless communication system. Each base station for wireless communication comprises: a communication module; and a processor. The processor can receive signaling about a bandwidth part (BWP) from the base station, determine, on the basis of the signaling, an activated BWP among one or more BWPs set in an unlicensed band, and monitor a physical downlink control channel (PDCCH) in the activated BWP.
Claims9
1-20. (canceled)
A user equipment (UE) for use in a wireless communication system, the UE comprising:
- a communication module;
- and
- a processor for controlling the communication module,
- wherein the processor is configured to:
- monitor a physical downlink control channel (PDCCH) in a bandwidth part (BWP) of a cell operating in unlicensed band;
- and
- perform an operation based on the PDCCH,
- wherein, based on the BWP including a plurality of listen-to-before transmission (LBT) bands, the monitoring is performed per LBT band and only on one or more configured LBT bands among the plurality of LBT bands in the BWP.
A method for use by a user equipment (UE) in a wireless communication system, the method comprising:
- monitoring a physical downlink control channel (PDCCH) in a bandwidth part (BWP) of a cell operating in unlicensed band;
- and
- performing an operation based on the PDCCH,
- wherein, based on the BWP including a plurality of listen-to-before transmission (LBT) bands, the monitoring is performed per LBT band and only on one or more configured LBT bands among the plurality of LBT bands in the BWP.
A base station (BS) for use in a wireless communication system, the BS comprising:
- a communication module;
- and
- a processor for controlling the communication module,
- wherein the processor is configured to:
- transmit a physical downlink control channel (PDCCH) in a bandwidth part (BWP) of a cell operating in unlicensed band;
- and
- perform an operation based on the PDCCH,
- wherein, based on the BWP including a plurality of listen-to-before transmission (LBT) bands, the transmitting is performed per LBT band and only within one or more configured LBT bands among the plurality of LBT bands in the BWP.
A method for use by a base station (BS) in a wireless communication system, the method comprising:
