摘要： A method and system is disclosed that requests a retransmission through base station cooperation in a communication system. The method for performing a retransmission request includes: receiving data from a main base station; transmitting a retransmission request of the received data; and receiving the data from the main base station in response to the retransmission request. A sub base station performing cooperation communication with the main base station receives the retransmission request from the mobile station and changes the format of transmission with respect to mobile stations communicating with the sub base station. The method and system can allow only a small amount of information to be exchanged among base stations in a base station cooperation system, thereby effectively reducing inter-cell interference and increasing the probability of successfully receiving retransmitted data.
