Abstract

一种数据收发方法及基站，所述方法应用于一种基站，所述基站包括：至少两个收发设备、与所述收发设备连接的至少两根天线；其中，覆盖同一基站扇区的天线与至少两个收发设备连接，且覆盖同一基站扇区的且与同一收发设备连接的天线中包括具有接收数据功能的天线和具有发送数据功能的天线；所述方法包括：所述收发设备通过与自己连接的每根天线，接收每根天线所覆盖基站扇区发送的数据信号和/或向每根天线所覆盖基站扇区发送数据信号。

Description

一种基站及数据收发方法 技术领域
本发明涉及通信技术领域，具体涉及一种基站及数据收发方法。
背景技术
基站可设在小区的中心，用全向天线形成圆形的覆盖区，也可将基站设在每个小区六边形的三个顶点上，每个基站采用三副120度扇形辐射的定向天线，分别覆盖三个相邻小区的各三分之一的区域，每个小区由三副120度扇形天线共同覆盖，而每副天线覆盖的区域就是一个基站扇区。
在LTE无线覆盖系统中，通常采用多入多出(Multiple-Input Multiple-Output，简称MIMO)技术来提高系统容量，MIMO技术是指在发射端和接收端分别使用多个发射天线和接收天线，使信号通过发射端与接收端的多个天线传送和接收，从而改善通信质量。参见图1所示的MIMO系统原理图。发射端将要发送的数据信号进行空时编码后映射到多根天线上发送出去，接收端将各根天线接收到的信号进行空时译码从而恢复出发射端发送的数据信号。
当基站采用MIMO的方式对三个扇区进行覆盖时，即由收发设备1连接的两个天线覆盖扇区1、由收发设备2连接的两个天线覆盖扇区2、由收发设备3连接的两个天线覆盖扇区3(参见图2个所示的扇区覆盖示意图之一)，若其中一个收发设备比如收发设备1出现故障(参见图3个所示的扇区覆盖示意图之二)，将不能保证对扇区1的信号覆盖，从而将不能保证扇区1内的基本业务需求。参见图4所示的通过开关矩阵实现扇区覆盖的示意图，为解决上述缺陷，现有技术采用与接收机1连接的主集天线1和分集天线1对扇区1进行覆盖，采用与接收机2连接的主集天线2和分集天线2对扇区2进行覆盖，采用与接收机3连接的主集天线3和分集天线3对扇区3进行覆盖，当其它一个扇区对应的收发设备比如接收机1故障时，可通过开关矩阵400使得分集天线1与没有发生故障的接收机2接通，从而通过接收机2以及分集天线1保证对扇区1的信号覆盖。
但是，采用开关矩阵400实现扇区覆盖存在以下缺陷：
1、开关矩阵400构造复杂，需要增加额外的制造成本。
2、增加开关矩阵400便相当于新增加了一个故障点，降低了系统可靠性。
3、开关矩阵400增加了链路损耗，降低了正常覆盖范围。
发明内容

具体实施方式
为使本发明实施例的目的、技术方案和优点更加清楚，下面将结合本发明实施例中的附图，对本发明实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例是本发明一部分实施例，而不是全部的实施例。基于本发明中的实施例，本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例，都属于本发明保护的范围。
现有基站设备通常采用多入多出(Multiple-Input Multiple-Output，简称MIMO)技术来收发数据，即使用多个发射天线传送数据信号，使用多个接收天线接收数据信号，通过多个天线实现数据的多发多收，这样可以在不增加频谱资源和天线发射功率的情况下，可以成倍的提高系统信道容量。在具体实现时，基站的基带模块将基带数据发送至基站的收发设备，收发设备再将该基带数据转换为射频信号并通过与自己连接的天线将该射频信号发射出去，以便该天线所覆盖基站扇区中的设备接收该射频信号，反之亦然。
当采用MIMO技术实现数据的多发多收时，若出现收发设备故障的情况，现有技术则通过增加外接设备(开关矩阵)的方式来保证对每一基站扇区的正常信号覆盖。为避免现有技术中因增加外接设备所带来的缺陷，本发明实施例不增加任何外接设备，而是通过改变天线与收发设备之间的连接方式，以在收发设备出现故障时保证对对每一基站扇区的正常信号覆盖。
下面对本发明实施例进行具体介绍。
参见图5，为本发明实施例提供的基站的组成示意图，该基站包括：至少两个收发设备、与所述收发设备连接的至少两根天线，即，包括收发设备1、收发设备2、……收发设备N，包括与收发设备1连接的A根天线，与收发设备2连接B根天线，……，与收发设备N连接的C根天线，N、A、B和C均为大于等于2的整数。其中，覆盖同一基站扇区的天线与至少两个收发设备连接，且覆盖同一基站扇区的且与同一收发设备连接的天线中包括具有接收数据功能的天线和具有发送数据功能的天线。
所述收发设备，用于通过与自己连接的接收天线，接收该接收天线所覆盖的基站扇区发送的数据信号，和/或，通过与自己连接的发射天线，向该发射天线所覆盖的基站扇区发送数据信号。
在本发明实施例中，对于每个基站扇区，将覆盖该基站扇区的所有天线划分为至少两批，天线批数小于或等于收发设备的个数，其中，每批天线分别与不同的收发设备连接、且每批天线中包括具有接收数据功能的天线和具有发送数据功能的天线。这样，有两个或两个以上的收发设备为该基站扇区服务，当其中一个收发设备故障时，由于还存在其它未发生故障的收发设备，通过与这些未发生故障的收发设备连接的接收天线和发射天线，还可以继续对该基站扇区进行正常的信号覆盖。
可见，本发明实施例在不引用外接设备的基础上，对现有天馈链路进行重新组合，即不再利用一个收发设备只服务于一个基站扇区，而是利用多个收发设备服务于同一基站扇区，以防止单个收发设备故障造成某一基站扇区的业务中断，从而保证基本的业务需求。同时，将基带数据动态分配给每一基站扇区对应的至少两个收发设备、和/或每一收发设备接收不同扇区发送的数据。
下面根据天线性质，分四种情况介绍本发明实施例。
(1)、若覆盖同一基站扇区的每根天线均具有收发数据功能，则覆盖同一基站扇区的且与同一收发设备连接的天线中包括具有接收数据功能的天线和具有发送数据功能的天线，具体为：覆盖同一基站扇区的且与同一收发设备连接的天线中，包括至少一根具有收发数据功能的天线。
举例说明：参见图6所示的扇区覆盖示意图之一，假设有6根基站天线 且每根天线既具有接收数据的功能又具有发送数据的功能，在这6根天线中，天线11和天线12覆盖扇区1，天线21和天线22覆盖扇区2，天线31和天线32覆盖扇区3。将天线11和天线21与收发设备1连接，将天线22和天线31与收发设备2连接，将天线12和天线32与收发设备3连接，由于采用两个收发设备服务于同一基站扇区，因此，当其中一个基站扇区故障时，比如收发设备1故障时，虽然，不能通过天线11覆盖扇区1且不能通过天线21覆盖扇区2，但还可以继续通过收发设备3和与收发设备3连接的具有收发数据功能的天线12来保证对扇区1的信号覆盖，通过收发设备2和与收发设备2连接的具有收发数据功能的天线22保证对扇区2的信号覆盖。

(3)、若覆盖同一基站扇区的所有天线中包括具有收发数据功能的天线和仅具有收数据功能的天线，则覆盖同一基站扇区的且与同一收发设备连接 的天线中包括具有接收数据功能的天线和具有发送数据功能的天线，具体为：覆盖同一基站扇区的且与同一收发设备连接的天线中，包括至少一根具有收发数据功能的天线、或包括至少一根具有收发数据功能的天线和至少一根仅具有收数据功能的天线。

(4)、若覆盖同一基站扇区的所有天线中包括具有收发数据功能的天线和仅具有发数据功能的天线，则覆盖同一基站扇区的且与同一收发设备连接的天线中包括具有接收数据功能的天线和具有发送数据功能的天线，具体为：覆盖同一基站扇区的且与同一收发设备连接的天线中，包括至少一根具有收发数据功能的天线、或包括至少一根具有收发数据功能的天线和至少一根仅具有发数据功能的天线。
举例说明：参见图9所示的扇区覆盖示意图之四，假设有12根基站天线，其中，天线11、12、21、22、31、32既具有接收数据的功能又具有发送数据的功能，天线13、14、23、24、33、34仅具有发送数据的功能，在这12根天线中，天线11、12、13和14覆盖扇区1，天线21、22、23和24覆盖扇区2，天线31、32、33和34覆盖扇区3。将天线12、13、14和21与收发设备1连接、将天线22、23、24和31与收发设备2连接，将天线11、32、33 和34与收发设备3连接，由于采用两个收发设备服务于同一基站扇区，因此，当其中一个基站扇区故障时，比如收发设备1故障时，虽然，不能通过天线12、13和14覆盖扇区1且不能通过天线21覆盖扇区2，但还可以继续通过收发设备3和与收发设备3连接的具有接收和发送数据功能的天线11来保证对扇区1的信号覆盖，通过收发设备2和与收发设备2连接的具有接收和发送数据功能的天线22和仅具有发送数据功能的天线23和24来保证对扇区2的信号覆盖。
