Abstract: Provided are a method for monitoring a control channel in an unlicensed band and an apparatus using the same. In an unlicensed cell, a user equipment (UE) monitors a physical downlink control channel (PDCCH) having burst control information in a search space defined in a control region of a subframe. The control region comprises a plurality of control channel elements (CCEs) starting from an index 0, and the search space is defined only in, from among the plurality of CCEs, first four CCEs and first eight CCEs.

Abstract: Provided are a method for determining a valid subframe for cell in a non-licensed band in a wireless communication system, and a wireless apparatus using the method. The method comprises: determining whether all orthogonal frequency division multiplexing (OFDM) symbols of the cell are usable; and when all of the OFDM symbols of the subframe are usable, determining whether the subframe is a valid subframe based on whether a channel state information-reference signal (CSI-RS) resource is present in the subframe.

Abstract: Provided is a method for performing channel sensing by a node. The node receives information about a known signal to be transmitted by at least one node of a node group that the node performing the channel sensing belongs to, detects the known signal using the information about the known signal, cancels reception power of the known signal from measured reception power, during a time period in which the known signal is detected, compares remaining reception power except for the reception power with a threshold, and determines whether a channel is occupied or unoccupied according to the comparison. The information about the known signal includes a sequence of the known signal, a power offset between a transmission signal and the known signal during a valid duration of the reception power of the known signal, or a cancellation ratio of reception power of the transmission signal during the valid duration.

Abstract: An aperiodic channel state reporting method in a wireless communication system, according to an embodiment of the present invention, is performed by means of a terminal. And the method comprises the steps of: receiving an aperiodic channel state information (CSI) report request from a base station; and calculating aperiodic CSI with respect to objects for CSI measurement indicated by means of the aperiodic CSI report request and then transmitting same to the base station, wherein, if valid measurement resources do not exist during a particular time interval with respect to the particular objects for CSI measurement indicated by means of the aperiodic CSI report request, the aperiodic CSI with respect to the objects for CSI measurement can be set as a particular indication value and be transmitted.

Abstract: Provided are a method for transmitting uplink in an unlicensed band and a device using the same. The device performs a clear channel assessment (CCA) inside a transmission window in an unlicensed band to thereby confirm whether a channel is idle. When the channel is idle, the device transmits an uplink transmission block inside the transmission window in the unlicensed band.

Abstract: Disclosed are an uplink data transmission method in a wireless communication system and a device therefor. Particularly, a method for transmitting uplink data in an unlicensed band by a user equipment (UE) in a wireless communication system may comprise the steps of: receiving, from a base station, uplink scheduling information within a cell operating in an unlicensed band; sensing a channel of the cell; transmitting a reservation signal when the channel is sensed to be in an idle state; and transmitting, to the base station, uplink data in a wireless resource allocated on the basis of the uplink scheduling information, wherein the channel is sensed to be in the idle state when energy detected, except for the reservation signal transmitted from another UE that is co-scheduled along with the UE for uplink multi-user multiple input multiple output (UL MU-MIMO) transmission, is smaller than a predetermined threshold value.
