Abstract: A method for transmitting and receiving a signal in a terminal of a mobile communication system, according to one embodiment of the present specification, comprises the steps of: receiving information of another terminal from the other terminal; transmitting, to a base station, a message requesting allocation of an identifier for the other terminal on the basis of the received information of the other terminal; and receiving, from the base station, the message including the identifier allocated for the other terminal. The provided present invention, according to one embodiment of the present specification, allows only the arbitrary receiver to access the base station and receive data therefrom when a plurality of densely located receivers are neighboring each other. At this point, the other receivers can selectively receive a data stream transmitted to each terminal from data channels received by the arbitrary receiver that accesses the base station. To this end, only the arbitrary terminal accessing at least the base station is enabled to allow feedback of the channel.
