    Abstract: A method of receiving a downlink signal by a terminal in a wireless communication system according to an embodiment of the present invention includes: transmitting, to a serving base station, an antenna selection index for selecting M of N antennas (where N>M and both N and M are positive integers) in a specific base station and a pre-coding matrix indicator PMI suitable for the M antennas; and receiving, from the specific base station, the downlink signal on which pre-coding is performed by using a pre-coding determined based on the antenna selection index and the pre-coding matrix indicator, wherein the antenna selection index may indicate any one of the antenna selection vectors that belong to an antenna selection codebook consisting of all the antenna selection vectors or a subset of all the antenna selection vectors for selecting at least one of the N antennas in the specific base station.

    Abstract: The present disclosure relates to a wireless communication system. Particularly, a communication method and an apparatus for the same are provided, in which configuration information related to random access of a user equipment (UE) is received from an upper node, first time resource information related to random access of the relay node is received from the upper node, and random access is performed to the upper node based on the configuration information and the first time resource information. The configuration information includes second time resource information including a periodicity of the random access of the UE and a plurality of random access occasions within the periodicity, and the first time resource information and the second time resource information do not overlap with each other in time resources.
