Abstract:
1. A method of performing communication in a wireless communication system supporting a multi-radio access technology (RAT) through cooperation between a first terminal requesting client cooperation (CC) and a second terminal accepting the CC, the method comprising: transmitting, by the first terminal, resource allocation request information regarding uplink (UL) transmission of the second terminal to a base station, wherein the resource allocation request information is included in a cooperation request message; receiving, by the second terminal, a first UL grant in response to the resource allocation request information from the base station, wherein the first UL grant is received by being included in a cooperation response message transmitted from the base station in response to the cooperation request message, wherein the cooperation response message further includes information on the CC between terminals including the first terminal and the second terminal, wherein the information on the CC includes an execution mode, and wherein the execution mode includes one of a first mode in which data is transmitted through relaying between the terminals or a second mode in which at least two or more terminals simultaneously transmit data; transmitting, by the first terminal, data to the second terminal; and transmitting, by the second terminal, to the base station the data received from the first terminal by using a resource allocated by the first UL grant.
