Abstract: A method for transmitting channel state information (CSI) by a user equipment in a wireless communication system is discussed. The method includes receiving a transmission burst; measuring the CSI based on the transmission burst; and transmitting the measured CSI, wherein the transmission burst is received in at least a first time resource and a second time resource, wherein the first time resource is configured as a first number of orthogonal frequency divisional multiplexing (OFDM) symbols, wherein the second time resource is configured as a second number of OFDM symbols, wherein the first number is smaller than the second number, and wherein the first time resource is considered to be an invalid time resource for the CSI.

Abstract: A method and apparatus for allocating resources for a sidelink transmission in a wireless communication system is provided. A user equipment (UE) selects a first carrier, i.e. anchor carrier, among multiple carriers, and allocates a first resource on the first carrier. The UE allocates a second resource on a second carrier, i.e. non-anchor carrier, based on an offset from the first resource on the first carrier. The UE performs the sidelink transmission by using the first resource on the first carrier and the second resource on the second carrier.

Abstract: The present invention relates to a resource allocation method of a vehicle-to-everything (V2X) transmission terminal in a wireless communication system and an apparatus therefor. More specifically, the method comprises the steps of: transmitting, to a V2X receiving terminal, a first V2X signal for a V2X service; receiving, from the V2X receiving terminal, an acknowledgment/negative-acknowledgment (ACK/NACK) for a V2X signal; and, if the NACK is received from the V2X receiving terminal, allocating, for a second V2X signal, a second time-frequency resource reserved in association with a first time-frequency resource for the first V2X signal.

Abstract: A method by which a terminal receives a downlink control channel in a wireless communication system is disclosed. Particularly, the method monitors candidate physical downlink control channels (PDCCHs) composed of control channel elements (CCEs), the number of which corresponds to an aggregation level, so as to receive a PDCCH, wherein CCEs for candidate PDCCHs of a higher aggregation level include all of the CCEs for candidate PDCCHs of a lower aggregation level, and the CCEs for candidate PDCCHs of the lower aggregation level included in each of the candidate PDCCHs of the higher aggregation level can be determined using a matrix on the basis of the magnitude of the higher aggregation level and the number of the candidate PDCCHs of the higher aggregation level.
