Description

上行干扰处理方法、设备和系统 技术领域
本发明实施例涉及通信技术领域,尤其涉及一种上行干扰处理方法、设备和系统。
背景技术
接入不同基站的用户设备(英文:User Equipment,简称:UE),例如:UE0执入基站0,UE1接入基站1,UE0发送给基站0的上行数据会对UE1发送给基站1的上行数据产生干扰,因此需要采用上行协作多点干扰消除技术(英文:Coordinated Multiplex Point Interference Cancellation,简称:CoMP IC)来实现不同基站下UE的上行数据间的干扰抑制,通过消除干扰UE的上行数据来提升被干扰UE的上行传输性能,以显著提升被干扰UE的上行吞吐量。
现有技术中,以UE0作为干扰UE,UE1作为被干扰UE为例进行说明,基站1会同时接收到UE0与UE1发送的上行数据,UE0的上行数据会对UE1的上行数据产生干扰。首先基站0向基站1发送UE0的信息,然后基站1接收UE1的上行空口数据和UE0的上行空口数据,UE1解析UE1的上行空口数据,当解析错误时,UE1向基站0发送UE0至基站1的信道信息,基站0根据UE0的上行数据与UE0至基站1的信道信息,重构UE0的上行空口数据并发送给基站1,基站1可以消除UE0的上行空口数据,然后可以正解解析UE1的上行空口数据,从而提高了UE1的上行传输性能。
但是,在上述方案中,基站0与基站1之间需要交互三次,当基站0与基站1之间的交互通道的带宽与时延存在约束时,上述方案难以实现。

本实施例中,该第一网络设备可以接收第一上行空口数据,该第一上行空口数据包括该第一UE的上行空口数据和该第二UE的上行空口数据,可选地,该第一上行空口数据还可以包括其它UE的上行空口数据,该第一UE接入该第一网络设备,即该第一网络设备为该第一UE的服务网络设备;该第一UE的上行空口数据为该第一UE发送的上行空口数据,该第一UE发送的上行空口数据可以被除该第一网络设备之外的其它网络设备接收,该第二UE的上行空口数据为该第二UE发送的上行空口数据,该第二UE发送的上行空口数据被第一网络设备和第二网络设备接收,但是限定其它网络设备是否接收。

本实施例中,第一网络设备在获得消除或减少第二UE的上行空口数据干扰的第二上行空口数据之后,该第一网络设备根据该第一UE的信息,解析该第二上行空口数据,获得该第一UE的上行空口数据的解析结果。由于获得第一UE的上行空口数据的解析结果所依据的上行空口数据已消除或减少了第二UE的上行空口数据的干扰,所以提高了获得的该第一UE的上行空口数据的解析结果正确率,提高了第一UE的上行传输性能。
本实施例中,通过第一网络设备接收第二网络设备发送的第二UE的信息以及接收到第一上行空口数据后,当第一UE的上行空口数据解析错误时,根据所述第二UE的信息,重构所述第二UE的上行空口数据,获得所述第二UE的重构上行空口数据,从第一上行空口数据消除该第二 UE的重构上行空口数据,从而获得第二上行空口数据,以降低或减少第二UE的干扰,再根据第一UE的信息,解析第二上行空口数据,获得第一UE的上行空口数据的解析结果,从而可以提高第一UE的上行空口数据的解析结果的正确率,提高了第一UE的上行传输性能。与现有技术相比,第一网络设备与第二网络设备交互次数减少,从而可以降低带宽和时延的要求,在网络设备间的交互通道的带宽与时延存在约束时,也可以实现提高UE的上行传输性能。

本发明实施例提供的上行干扰处理方法,通过第二网络设备向第一 网络设备发送第二UE的信息;第一网络设备接收第一上行空口数据,还可以接收第二网络设备发送的第二UE的上行空口数据的解析结果,以及根据第一UE的信息,解析所述第一上行空口数据;当第一UE的上行空口数据解析失败时,根据所述第二UE的信息、所述第二UE至所述第一网络设备的信道信息和所述第二UE的上行空口数据的解析结果,重构空口数据,获得所述第二UE的重构上行空口数据,再从所述第一上行空口数据中消除所述第二UE的重构上行空口数据,获得第二上行空口数据,然后根据所述第一UE的信息,解析所述第二上行空口数据,获得所述第一UE的上行空口数据的解析结果;从而可以提高第一UE的上行空口数据的解析结果的正确率,提高了第一UE的上行传输性能。而且第一网络设备与第二网络设备交互两次,而且这两种交互是单向传输,降低了带宽和时延要求,在网络设备间的交互通道的带宽与时延存在约束时,也可以实现提高第一UE的上行传输性能。
在本发明方法实施例三的基础上,可选地,在执行S307之前,该第一网络设备可以判断该第一网络设备开始接收该第一上行空口数据到开始接收该第二UE的上行空口数据的解析结果之间的时间间隔是否大于预设时间;当第一网络设备开始接收该第一上行空口数据到开始接收所述第二UE的上行空口数据的解析结果之间的时间间隔不大于预设时间时,则该第一网络设备执行S307。当所述第一网络设备开始接收所述第一上行空口数据到开始接收所述第二UE的上行空口数据的解析结果之间的时间间隔大于预设时间时,所述第一网络设备停止处理当前HARQ进程,并向所述第一UE发送ACK消息;并且在在当前HARQ进程的下一个HARQ进程处理时刻到达时,该第一网络设备执行S306。
可选地,在第一网络设备开始接收该第一上行空口数据到开始接收所述第二UE的上行空口数据的解析结果之间的时间间隔大于预设时间时,该第一网络设备不执行S306-S308,而是向该第一UE发送否定确认(英文:Negative Acknowledgement,简称:NACK)。
图14为本发明实施例提供的应用场景的第二种示意图,如图14所示,第一UE接入第一网络设备,第二UE接入第二网络设备,第二UE发送的上行空口数据会被第一网络设备接收,从而第一网络设备所接收 的第二UE发送的上行空口数据会成为第一UE发送的上行空口数据的干扰,进而降低了第一UE的上行传输性能。现有技术中通过第一网络设备向第二网络设备发送第一UE的信息,第二网络设备接收到上行空口数据后,获得第二UE的上行空口数据解析结果,然后重构获得第二UE的重构上行空口数据,再从上行空口数据中消除第二UE的重构上行空口数据,将消除获得的上行空口数据发送给第一网络设备,由第一网络设备根据该第一网络设备接收的上行空口数据以及第二网络设备发送的上行空口数据,获得第一UE的上行空口数据的解析结果,从而可以提高第一UE的上行传输性能。但是第一网络设备与第二网络设备间需要交互大量数据,在交互通道存在带宽约束时上述方案难以实现。而本发明提供的下述各方法实施例均可以用于解决上述问题。
图15为本发明上行干扰处理方法实施例四的流程图,如图15所示,本实施例的方法可以包括:

S405、所述第一网络设备根据所述第一解析结果、所述指示信息和所述第二解析结果,获取所述第一UE的上行空口数据的解析结果。
本实施例中,第一网络设备根据解析获得的第一UE的上行空口数据的第一解析结果、接收到的第一UE的上行空口数据的第二解析结果和指示信息,获取最终的第一UE的上行空口数据的解析结果,即实现了第一UE的上行空口数据的联合接收,得到的第一UE的上行空口数据的解析结果的正确率增加,提高了第一UE的上行传输性能。
本发明实施例提供的下行干扰处理方法,通过第一网络设备向第二网络设备发送第一UE的信息,以及根据第一UE的信息解析接收的第四上行空口数据,获得所述第一UE的上行空口数据的第一解析结果,还接收所述第二网络设备发送的指示信息和所述第一UE的上行空口数据的第二解析结果,再根据所述第一解析结果、所述指示信息和所述第二解析结果,获取所述第一UE的上行空口数据的解析结果,从而可以提高第一 UE的上行空口数据的解析结果的正确率,提高了第一UE的上行传输性能。而且第一网络设备与第二网络设备交互的第一UE的上行空口数据的第二解析结果数据量较少,进而降低了带宽和时延要求,在网络设备间的交互通道的带宽与时延存在约束时,也可以实现提高第一UE的上行传输性能。
图16为本发明上行干扰处理方法实施例五的流程图,如图16所示,本实施例的方法可以包括:

S504、所述第二网络设备向所述第一网络设备发送指示信息和所述第二解析结果,所述指示信息用于指示所述第二解析结果正确或者错误。
本实施例中,当该第二解析结果正确时,该指示信息用于指示该第 二解析结果正确,当该第二解析结果错误时,该指示信息用于指示该第二解析结果错误。由于第二网络设备向第一网络设备发送的是第一UE的上行空口数据的解析结果而不是第二网络设备发送的上行空口数据,因此传输的数据量减少,降低了网络设备间的带宽要求。
本发明实施例提供的上行干扰处理方法,通过第二网络设备接收第一网络设备发送的第一UE的信息,根据所述第一UE的信息和接收的第五上行空口数据,获得所述第一UE的上行空口数据的第二解析结果,再向所述第一网络设备发送指示信息和所述第二解析结果,所述指示信息用于指示所述第二解析结果正确或者错误,使得第一网络设备根据所述第一解析结果、所述指示信息和以及第二网络设备解析获得的第一UE的上行空口数据的第二解析结果,获取所述第一UE的上行空口数据的解析结果,从而可以提高第一UE的上行空口数据的解析结果的正确率,提高了第一UE的上行传输性能。而且第一网络设备与第二网络设备交互的第一UE的上行空口数据的第二解析结果数据量较少,进而降低了带宽和时延要求,在网络设备间的交互通道的带宽与时延存在约束时,也可以实现提高第一UE的上行传输性能。

S604、所述第二网络设备接收第五上行空口数据。

可选地,所述第一网络设备将所述第一解析结果以及所述第二解析结果进行合并,获得所述第一UE的上行空口数据的解析结果之后,还包括:当所述第一UE的上行空口数据的解析结果错误时,所述第一网络设备通过PDCCH向所述第一UE发送重传信息。具体地,当将第一解析结果与第二解析结果进行合并获得的第一UE的上行空口数据的解析结果错误时,该第一网络设备还可以向该第一UE发送重传信息,使得第一UE接收到该重传信息后,再重新发送该第一UE的上行空口数据。
可选地,当所述第一网络设备开始接收所述第四上行空口数据到开始接收所述指示信息和所述第二解析结果之间的时间间隔大于预设时间时,所述第一网络设备停止处理当前HARQ进程,并向所述第一UE发送确定ACK消息;所述第一网络设备根据所述第一解析结果、所述指示信息和所述第二解析结果,获取所述第一UE的上行空口数据的解析结果,包括:在当前HARQ进程的下一个HARQ进程处理时刻到达时,所述第一网络设备根据所述第一解析结果、所述指示信息和所述第二解析结果,获取所述第一UE的上行空口数据的解析结果。
具体地,第二网络设备向第一网络设备发送指示信息和该第一解析结果,此处存在一个第一网络设备与第二网络设备的交互时延2,本发明实施例还提供了在时延较大时的处理方案。第一网络设备在执行S607的第三种可行的实现方式之前,该第一网络设备可以判断该第一网络设备开始接收该第四上行空口数据到开始接收该指示信息和第二解析结果之间的时间间隔是否大于预设时间;当该第一网络设备开始接收该第四上行空口数据到开始接收该指示信息和第二解析结果之间的时间间隔不大于预设时间时,则该第一网络设备直接执行S607的第三种可行的实现方式。当该第一网络设备开始接收该第四上行空口数据到开始接收该指示信息和第二解析结果之间的时间间隔不大于预设时间时,所述第一网络设备停止处理当前HARQ进程,并向所述第一UE发送确认(英文:Acknowledgement,简称:ACK)消息;并且在当前HARQ进程的下一个HARQ进程处理时刻到达时,该第一网络设备执行S607的第三种可行的实现方式。从而解决了现有技术中在第一网络设备接收第二网络设备发送的第一UE的上行空口数据的时延过大时,不能根据该第一网络设备接收的上行空口数据以及第二网络设备发送的上行空口数据获得第一UE的上行空口数据的解析结果,进而不能提升第一UE的上行传输性能的技术问题。
