摘要： Proposed is a method for a first device for communicating wirelessly. The method may comprise a step for receiving first control information in a first search space related to the first control information, and receiving second control information in a second search space related to the second control information. For example, on the basis of a base station allocating resources related to sidelink transmission to the first device in a carrier in which Uu communication is performed, the first search space related to the first control information and the second search space related to the second control information may overlap.

摘要： The present invention relates to a wireless access system supporting an unlicensed band, and to a method for performing a clear channel assessment (CCA) or a LBT, and an apparatus for supporting the same. As one embodiment of the present invention, the method by which a terminal performs a CCA in the wireless access system supporting an unlicensed band comprises the steps of: receiving resource allocation information indicating a resource region allocated in the unlicensed band; performing the CCA only for the resource region; and transmitting uplink data through the resource region when the resource region is in an idle state.

摘要： A method and a device for a sidelink in a wireless communication system are provided. A transmission terminal supporting a sidelink performs transmission/reception beam pairing by using control information for a sidelink. The transmission terminal and a reception terminal can find an optimum transmission/reception beam pair on the basis of a method of repeatedly transmitting/receiving control information by the sidelink. Therefore, an appropriate transmission/reception beam pair can be found without repeatedly transmitting a synchronization signal. The reception terminal can provide feedback information on the received control information to the transmission terminal. The transmission terminal can determine an optimum transmission/reception beam pair on the basis of the feedback information.
