摘要： A method, a device and a system for precoding based on CoMP are provided. The method includes: a serving base station receives an expected PMI of a terminal associated with the serving base station and a leakage PMI of a terminal associated with a cooperation base station, which is sent by the cooperation base station, wherein the expected PMI is corresponding to encoding codeword in an expected terminal direction, and the leakage PMI is corresponding to encoding codeword in an interference direction; the serving base station selects expected encoding codeword according to the expected PMI and selecting leakage precoding codeword according to the leakage PMI; and the serving base station convolve the expected encoding codeword and the leakage precoding codeword to obtain precoding codeword used for signal transmission by the serving base station. In the present invention, by use of the CoMP technology, the accuracy of reducing interference of edge user terminals is improved.
摘要翻译：提供了一种基于CoMP进行预编码的方法，装置和系统。该方法包括：服务基站接收与服务基站相关联的终端的期望PMI和由协作基站发送的与协作基站相关联的终端的泄漏PMI，其中预期PMI对应以期望终端方向编码码字，并且所述泄漏PMI对应于干扰方向上的编码码字; 服务基站根据预期PMI选择预期编码码字，并根据泄漏PMI选择泄漏预编码码字; 并且服务基站卷积期望的编码码字和泄漏预编码码字以获得由服务基站用于信号传输的预编码码字。在本发明中，通过使用CoMP技术，能够提高边缘用户终端的干扰降低的精度。
