Abstract: Provided are a method for coordinated multi-point (CoMP) transmission in an unlicensed band and a device using the same. In the unlicensed band, the device receives, from one transmission point (TP) of a plurality of TPs, a physical downlink control channel (PDCCH) having scheduling information for scheduling a physical downlink shared channel (PDSCH). The device decodes, according to the scheduling information, the PDSCH with respect to at least one TP, which has successfully detected the PDSCH, among the plurality of TPs.

Abstract: Disclosed herein is a method for transmitting a signal to or receiving a signal from a base station by a terminal in a wireless communication system. Specifically, the method comprises the steps of: receiving a first packet from the base station; transmitting, to the base station, a negative-ACK(NACK) response to the first packet; receiving a second packet from the base station and determining whether an error has occurred in the NACK response to the first packet; and transmitting, to the base station, information on whether an error has occurred in the NACK response to the first packet.

Abstract: The disclosure of the present invention proposes a communication method. The method may be performed by a wireless device and comprise: if a full duplex of a downlink (DL) reception and an uplink (UL) transmission is configured in an uplink carrier spectrum including a DL portion and a UL portion, considering that the DL portion in the uplink carrier spectrum is configured as protected DL portion for another device configured with non full-duplex. Here, the protected DL portion may allow the device configured with a non full-duplex to perform a UL transmission in the protected DL portion at a low power. The DL portion and the UL portion may be flexibly configured in the uplink carrier spectrum.

Abstract: Disclosed is a method for performing a synchronization by a device-to-device (D2D) terminal in a wireless communication system supporting D2D communication. More particularly, a method for performing a synchronization by a D2D terminal comprises the steps of: receiving a synchronization reference signal from a first synchronization source and performing a synchronization; and, if the quality of the synchronization reference signal does not meet a predetermined standard, changing the synchronization source into a second synchronization source.

Abstract: A method of receiving control information for a device-to-device (D2D) communication by a user equipment (UE) in a wireless communication system. The method includes receiving a configuration for radio resources for the D2D communication; and receiving a downlink control information (DCI) on a specific radio resource among the radio resources, according to the configuration. If the DCI configured with a DCI format 0 is scrambled with a semi-persistent scheduling (SPS)—radio network temporary identifier (RNTI) for the UE specific, the DCI is considered as a valid semi-persistent activation or release.

Abstract: A method for device-to-device direct communication in a wireless communication system according to an embodiment of the present invention is performed by a first terminal, and the method comprises the steps of: setting, as a transmission gap period, a candidate time period in which a first message including location information of a second terminal will be periodically received from the second terminal; and periodically receiving the first message from the second terminal within the transmission gap period. A message is not transmitted from the first terminal through a candidate carrier on which the first message is to be received within the transmission gap period.

Abstract: The present invention relates to a wireless access system supporting an unlicensed band, various methods for adjusting a contention window size, methods for performing a carrier sensing process in a single engine and a multi-engine, and an apparatus supporting the same. As one embodiment of the invention, a method for adjusting a contention window size (CWS) in a wireless access system supporting an unlicensed band may comprise: a step of setting a contention window size (CWS) necessary for performing a channel access process for each of priority classes; a step of performing a channel access process for a particular priority class in a channel in an unlicensed band on the basis of the set CWS; a step of performing a downlink transmission related to the particular priority class if it is determined that the channel in the unlicensed band is in an idle state as a result of the channel access process; and a step of making adjustments for all CWS' of priority classes if a triggering event, which relates to a downlink transmission and increases or reduces the CWS for the particular priority class, occurs.
