Abstract

本发明实施例提供一种多点协作接收处理方法、装置和基站，该方法包括：对M个协作集中的k个协作集接收到的上行信号进行解调译码，得到k个循环冗余校验码CRC检测结果，其中，所述上行信号为用户设备UE发送的，所述协作集为所述UE所在的服务扇区或者所述服务扇区与任意一个或多个协作扇区形成的集合；M≥2，1≤k≤M；若所述k个CRC检测结果中包含至少一个正确的CRC检测结果，则对所述至少一个正确的CRC检测结果中的一个CRC检测结果得到的信号进行处理。本发明实施例，基站通过CRC检测，可以避免现有技术中SINR的误差值较大的问题，并且可以提高选择协作集的准确性，从而可以提高实际信道估计下的检测性能。
