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.
摘要翻译：本发明涉及用于通过多个基站向多个通信终端提供通信服务的基站之间的协作的系统和方法。当获取通信终端的信道状态信息时，服务基站从码本中选择与信道状态信息相匹配的服务信道码，使用服务信道码和信道状态信息计算线性变换信息，并发送服务信道码到合作基站。当协作基站接收到协作信道码时，服务基站使用服务信道码和协作信道码来计算服务基站的服务权重信息和合作基站的协作权重信息，并且确定波束形成向量通过将线性变换信息应用于服务权重信息。根据本发明，在基站将信道状态信息变换为信道码之前，对信道状态信息进行线性变换，从而预测信道状态信息与系统中的信道码之间的量化损失，用于基站车站。此外，当在用于基站之间的协作的系统中提供通信服务时，基站可以恢复量化损失。这导致系统中基站之间的基站之间的合作的协作性能得到改善。
