    Abstract: One embodiment of the present invention is a method in which a terminal transmits an acknowledgement of reception performed through an enhanced physical downlink control channel (EPDCCH) in a wireless communication system, the method comprising the steps of: decoding the EPDCCH in both a first EPDCCH physical resource block (PRB) set and a second EPDCCH PRB set; and transmitting an acknowledgement of reception performed through each EPDCCH. The resource indices for transmitting an acknowledgement of reception performed through each EPDCCH are determined in mutually different manner based on the type of the EPDCCH PRB set, whether or not the number of the PRB pairs contained in each EPDCCH PRB set corresponds to each other, and/or whether or not the EPDCCH PRB sets overlap.

    Abstract: The present invention discloses a method and device for performing coordinated precoding in a wireless access system. In particular, the present invention includes: transmitting, to a base station, a measurement result of a plurality of interference signals by a terminal, the plurality of interference signals being transmitted from a plurality of adjacent base stations; receiving quasi-orthogonal CDM (Q-CDM) code information from the base station by the terminal in order to remove some of the plurality of interference signals, the Q-CDM code information being determined by the base station and the plurality of adjacent base stations; transmitting information on a channel state to the base station on the basis of a Q-CDM code by the terminal; and receiving downlink data, to which coordinated precoding is applied, from the base station by the terminal. Interference signals that have an intensity greater than a predetermined threshold from among the plurality of interference signals may be removed by using the Q-CDM code, and interference signals that have an intensity less than the predetermined threshold from among the plurality of interference signals may be removed by using null precoding.

    Abstract: One embodiment of the present invention relates to a method for transmitting, by a terminal, feedback on a signal from another terminal in a wireless communication system. The method for transmitting feedback information comprises the steps of: receiving signals transmitted by a plurality of terminals; and transmitting feedback information on each of at least parts of the received signals, wherein the feedback information is transmitted together with data of the terminal transmitting the feedback information, and the feedback information includes time information that allows the terminals that transmitted each of the parts of signals that are subject to the feedback to recognize that the feedback information is feedback on the signals transmitted by the same terminals. The UE is capable of communicating with at least one of another UE, a UE related to an autonomous driving vehicle, the BS or a network.
