摘要： In the communications system of the present invention, a communications terminal determines a precoding matrix index in a pilot signal received through a specific downlink channel, examines channel quality information of the downlink channel according to the determined precoding matrix index, and transmits feedback information to a serving base station, which determines a priority factor by using the examined channel quality information, and compares the priority factor with other priority factors. The comparison is used such that a base station having a high priority suggests the use of the precoding matrix to the neighboring base station.

摘要： The present invention relates to a system and to a method for the cooperation among base stations, in which a communication service is provided to a plurality of communication terminals through the plurality of base stations. When channel state information of a communication terminal is acquired, a serving base station selects a serving channel code matching the channel state information from a codebook, calculates linear transform information using the serving channel code and the channel state information, and transmits the serving channel code to a cooperative base station. When the cooperative base station receives a cooperation channel code, the serving base station calculates serving weight information of the serving base station and cooperation weight information of the cooperative base station using the serving channel code and the cooperation channel code, and determines a beam forming vector by applying the linear transform information to the serving weight information. According to the present invention, the channel state information is linearly transformed before the base station transforms the channel state information into the channel code, to thereby predict a quantization loss between the channel state information and the channel code in the system for the cooperation among base stations. In addition, the base station may recover the quantization loss when communication service is provided in the system for the cooperation among base stations. This leads to improved cooperation performance among base stations in the system for the cooperation among base stations.

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.
