Abstract

通道联合校正方法和装置及系统，一种通道联合校正方法包括向第一RRU发送第一通道联合校正指令，向第二RRU发送第二通道联合校正指令，接收第二RRU发送的X2个业务通道中的X2个接收通道针对所述第一校正参考信号的接收结果；接收第一RRU发送的X1个业务通道中的X1个接收通道针对第二校正参考信号的接收结果；根据第一校正参考信号、X2个接收通道针对第一校正参考信号的接收结果、第二校正参考信号和X1个接收通道针对所述第二校正参考信号的接收结果，计算得到所述X1个业务通道和/或所述X2个业务通道的校正补偿系数。本发明实施例提供技术方案有利于让没有通道自校正功能的RRU之间实现通道校正。
