Abstract
The present invention relates to a wireless communication system, specifically to a method comprising the steps of configuring a PCell of a licensed band and an SCell of an unlicensed band for a base station; receiving resource configuration information concerning the SCell by means of a physical downlink control channel (PDCCH) of the PCell; configuring a subframe set within a temporary time duration on the SCell on the basis of the resource configuration information; and communicating with the base station by means of the subframe set temporarily configured on the SCell, and to an apparatus for the method.
Claims15
A base station (BS) configured to perform a communication in a wireless communication system, the BS comprising:
- at least one radio frequency (RF) unit that includes a transceiver;
- at least one processor connected to the RF unit;
- and
- at least one computer memory operably coupled to the at least one processor and, when executed, causing the at least one processor to perform operations,
- wherein the operations include:
- transmitting a downlink control information (DCI) for a plurality of frequency bands,
- wherein the DCI includes a plurality of information related with channel occupancies of the plurality of frequency bands;
- and
- performing the communication in a contiguous time period of at least one of the plurality of frequency bands, based on the DCI,
- wherein the plurality of information have a one-to-one mapping with the plurality of frequency bands, and each of the plurality of information indicates whether a corresponding one of the plurality of frequency bands is available or not until an end of the contiguous time period.
A method of performing a communication by a user equipment (UE) in a wireless communication system, the method comprising:
- receiving a downlink control information (DCI) for a plurality of frequency bands,
- wherein the DCI includes a plurality of information related with channel occupancies of the plurality of frequency bands;
- and
- performing the communication in a contiguous time period of at least one of the plurality of frequency bands, based on the DCI,
- wherein the plurality of information have a one-to-one mapping with the plurality of
- unlicensed frequency bands, and each of the plurality of information indicates whether a corresponding one of the plurality of frequency bands is available or not until an end of the contiguous time period.
A user equipment (UE) configured to perform a communication in a wireless communication system, the UE comprising:
- at least one radio frequency (RF) unit that includes a transceiver;
- at least one processor connected to the RF unit;
- and
- at least one computer memory operably coupled to the at least one processor and, when executed, causing the at least one processor to perform operations,
- wherein the operations include:
- receiving a downlink control information (DCI) for a plurality of frequency bands,
- wherein the DCI includes a plurality of information related with channel occupancies of the plurality of frequency bands;
- and
- performing the communication in a contiguous time period of at least one of the plurality of frequency bands, based on the DCI,
- wherein the plurality of information have a one-to-one mapping with the plurality of frequency bands, and each of the plurality of information indicates whether a corresponding one of the plurality of frequency bands is available or not until an end of the contiguous time period.
