- 根据权利要求20所述的方法,其特征在于,所述根据所述第一配对 RRU集合和所述配对UE集合,确定所述UE的第二配对RRU集合,包括:根据所述配对UE集合中各个UE的业务类型,确定各个UE的优先级;对所述配对UE集合中每个配对UE与所述UE进行相关性计算;依照优先级由高到低的顺序,依次判断各个配对UE与所述UE是否具有相关性;如果优先级最高的配对UE与所述UE具有相关性,则获取所述优先级最高的配对UE的工作RRU,将所述优先级最高的配对UE的工作RRU从所述第一配对RRU集合中删除,得到第二配对RRU集合;如果所述优先级最高的配对EU与所述UE不具有相关性,则按照优先级由高到低的顺序,依次判断所述配对UE集合中的其余配对UE与所述UE是否具有相关性;若所述配对UE集合中的其余配对UE中存在与所述UE具有相关性的配对UE,则按照处理所述优先级最高的配对UE得到第二配对RRU集合的方式处理与所述UE具有相关性的配对UE。
- 根据权利要求23所述的方法,其特征在于,所述按照优先级由高到低的顺序,依次判断所述配对UE集合中的其余配对UE与所述UE是否具有相关性之后,还包括:若所述配对UE集合中的其余配对UE中不存在与所述UE具有相关性的UE,则确定所述UE的实际用户属性为初始用户属性。
- 根据权利要求19所述的方法,其特征在于,所述根据所述第二配对RRU集合和所述UE的初始用户属性,确定所述UE的实际用户属性,包括:如果所述第二配对RRU集合中不存在为所述UE提供服务的RRU,则根据所述UE的初始用户属性,确定所述UE的实际用户属性;如果所述第二配对RRU集合中存在为所述UE提供服务的RRU,则按照优先级由高到低的顺序,重新根据所述配对UE集合中的其余配对UE与所述第一 配对RRU集合,确定新的第二配对RRU集合,直至新的第二配对RRU集合中不存在为所述UE提供服务的RRU。
- 根据权利要求25所述的方法,其特征在于,所述用户属性为全部联合调度用户、部分联合调度用户及独立调度用户;所述根据所述UE的初始用户属性,确定所述UE的实际用户属性,包括:如果所述UE的初始用户属性为全部联合调度用户,则确定所述UE的实际用户属性为部分联合调度用户;如果所述UE的初始用户属性为部分联合调度用户,则确定所述UE的实际用户属性为独立调度用户。
- 根据权利要求26所述的方法,其特征在于,所述根据所述UE的初始用户属性,确定所述UE的实际用户属性之后,还包括:如果所述UE为BF用户,则对所述UE的波束方向作加权处理。
