Description

一种天线端口配置方法及装置 技术领域
本申请涉及天线技术领域，尤其涉及一种天线端口配置方法及装置。
背景技术
现网的数字化室内分布系统中的射频拉远单元(Radio Remote Unit，RRU)都是2x2天线，即包括2个发射天线和2个接收天线。室内场景平层的空间隔离度较低时，不同RRU之间重叠区域(以下称之为“小区联合区域”)较大，同时由于室内空间相对封闭，小区联合区域受到的来自外部的干扰较小，重叠区域内的信干噪比高且相关性为低相关，可以获得较高的3流复用/4流复用的比例。
目前的数字化室内分布系统网络，在不增加RRU数量的情况下，可以通过将具有重叠的覆盖区域的两个RRU的天线端口的逻辑端口号配置为不同端口，使得两个RRU之间的联合区域内的4接收天线(4R)终端支持4x4虚拟多输入多输出(Multiple Input Multiple Output，MIMO)，从而提高4R终端的空间复用增益，获得更高的数据传输速率。
然而，当多个RRU共存时，如何配置每个RRU的天线端口，使得终端在所述多个RRU的覆盖区域内移动时，更容易进入使得终端支持4x4虚拟MIMO的小区联合区域，是亟待解决的问题。

具体实施方式
本申请实施例适用于4G(第四代移动通信系统)演进系统，如LTE(Long Term Evolution，长期演进)系统；5G(第五代移动通信系统)系统；CRAN(Cloud Radio Access Network，云无线接入网)等通信网络。
本申请实施例中，术语“终端”包括但不限于移动站、固定或移动用户单元、寻呼机、蜂窝电话、个人数字助理(Personal Digital Assistant，简称PDA)、计算机或任何其它类型的能在无线环境中工作的用户设备(user equipment)。术语“接入网设备”包括但不限于基站、节点、基站控制器、接入点(Access Point，AP)、远端节点或任何其它类型的能够在无线环境中工作的接口设备。
目前，4×4终端逐渐开始流行，但是现网中的数字化室内分布系统中的RRU还是2×2天线，因此终端每次只能最多通过2根天线进行收发数据，导致终端收发数据的传输速率受制于RRU。为了使得终端获得更高的数据传输速率，可以为相邻的两个RRU配置不同的天线端口。配置了不同天线端口的两个RRU在于同一个终端进行通信时，终端可以同时分别通过不同天线端口 与每个RRU通信，因此这两个RRU之间的小区联合区域内的终端能够通过4根天线进行收发数据，从而提高终端在RRU的覆盖区域内的空间复用增益，获得更高的数据传输速率。具体，如图1所示，为本申请实施例提供的一种通信架构示意图。图1中，RRU 101的天线端口的逻辑端口号配置为0和1，RRU 102的天线端口的逻辑端口号配置为2和3。RRU 102覆盖区域内的终端103只能通过天线端口2和3与RRU 102进行通信，而RRU 101与RRU102重叠的覆盖区域内的终端104可以同时通过天线端口0和1与RRU 101进行通信、以及通过天线端口2和3与RRU 102进行通信。
然而，当多个RRU共存时，如何合理配置每个RRU的天线端口，使得尽可能多的相邻的RRU之间配置为不同的天线端口，是亟待解决的问题。
基于上述描述，如图2所示，为本申请实施例提供的一种天线端口配置方法流程示意图，包括：
步骤201：接入网设备获取M个RSRP差值；所述M个RSRP差值指示出N个射频拉远单元RRU的无线信号强度，M以及N均为大于1的正整数。
其中，RSRP的英文全称为Reference Signal Receiving Power，即参考信号接收功率，以下均简称为RSRP。
步骤202：所述接入网设备根据所述M个RSRP差值确定遍历所述N个RRU的遍历顺序。
步骤203：针对所述N个RRU中的任意一个RRU，所述接入网设备为所述遍历顺序中与所述RRU相邻的两个RRU配置相同的天线端口、为所述RRU与所述RRU相邻的RRU配置不同的天线端口。
步骤201中，接入网设备可以通过不同方式获取所述M个RSRP差值。
一种可能的实现方式中，所述N个RRU工作于时分复用(Time DivisionDuplexing，TDD)模式时，所述M个RSRP差值中的任意一个RSRP差值，为所述N个RRU中两个RRU的下行RSRP之间的差值。
在该实现方式中，所述N个RRU之间可以互相发送信号，由于RSRP可以用来衡量下行参考信号的功率，每个RRU从而可以通过接收其他RRU发 送的信号确定该RRU和其他RRU之间的RSRP差值，接入网设备从而能够确定出所述N个RRU的M个RSRP差值。
一种可能的实现方式中，所述N个RRU工作于频分复用(Frequency Division Duplexing，FDD)模式时，所述M个RSRP差值中的任意一个RSRP差值，为所述N个RRU中一个RRU的下行RSRP与终端的上行RSRP之间的差值。
在该实现方式中，所述N个RRU中的每个RRU向同一个终端发送信号，并接收所述终端发送的信号，接入网设备从而获得每个RRU的下行RSRP与终端的上行RSRP之间的差值，从而确定出M个RSRP差值。
需要说明的是，所述N个RRU可以不是与所述接入网设备通过通用公共无线电接口(Common Public Radio Interface，CPRI)等接口连接的RRU，所述N个RRU可以为处于同一个预设区域内的RRU。
接入网设备具体如何获取所述M个RSRP差值，本申请实施例并不限定。
步骤202中，接入网设备根据所述N个RRU工作的模式确定遍历所述N个RRU的遍历顺序，具体的，在所述N个RRU工作于TDD模式时，所述接入网设备可以根据以下步骤确定遍历所述N个RRU的遍历顺序：
步骤一、所述接入网设备从所述N个RRU中选择一个RRU作为目标RRU；
步骤二、所述接入网设备将所述M个RSRP差值中由所述目标RRU的下行RSRP确定的最小的RSRP差值作为目标RSRP差值。
步骤三、所述接入网设备将所述目标RRU进行标记，并将确定所述目标RSRP差值的另一个RRU作为新的目标RRU，并返回将所述M个RSRP差值中由所述目标RRU的下行RSRP确定的最小的RSRP差值作为目标RSRP差值的步骤，直至所述N个RRU中的所有RRU被标记。
需要说明的是，若确定出的新的目标RRU为被标记过的RRU，则重新在所述N个RRU中选择一个未标记的RRU作为目标RRU，并返回步骤二，即返回将所述M个RSRP差值中由所述目标RRU的下行RSRP确定的最小的 RSRP差值作为目标RSRP差值的步骤。
步骤四、所述接入网设备将所述N个RRU中每个RRU被标记的顺序确定为遍历所述N个RRU的遍历顺序。
通过上述方法，接入网设备可以确定每个RRU到所述N个RRU中其他RRU的最短路径，从而确定每个RRU的相对位置关系。
相应的，在所述N个RRU工作于FDD模式时，所述接入网设备可以根据以下步骤确定遍历所述N个RRU的遍历顺序：
步骤一、所述接入网设备将所述M个RSRP差值按照大小进行排序。
需要说明的是，所述接入网设备可以按照从大到小的顺序将所述M个RSRP差值进行排序，也可以按照从小到大的顺序将所述M个RSRP差值进行排序，本申请实施例。
步骤二、所述接入网设备按照排序后的所述M个RSRP差值的顺序，依次对每个RSRP差值对应的RRU进行标记；
步骤三、所述接入网设备将所述N个RRU中每个RRU被标记的顺序确定为遍历所述N个RRU的遍历顺序。
最后，在步骤203中，接入网设备根据遍历所述N个RRU的遍历顺序为每个RRU配置天线端口，具体的，针对所述N个RRU中的任意一个RRU，所述接入网设备将所述遍历顺序中与所述RRU相邻的两个RRU的天线端口的逻辑端口号配置为0和1、将所述RRU的天线端口的逻辑端口号配置为2和3；或者，针对所述N个RRU中的任意一个RRU，所述接入网设备将所述遍历顺序中与所述RRU相邻的两个RRU的天线端口的逻辑端口号配置为2和3、将所述RRU的天线端口的逻辑端口号配置为0和1。同时，针对所述N个RRU中的任意一个RRU，所述接入网设备还可以将所述遍历顺序中与所述RRU相邻的两个RRU的天线端口的逻辑端口号配置为0和1、将所述RRU的天线端口的逻辑端口号配置为2和3；或者，针对所述N个RRU中的任意一个RRU，所述接入网设备将所述遍历顺序中与所述RRU相邻的两个RRU的传输模式(transmission mode，TM)设置为TM4、将所述RRU的传输模式 设置为TM9。
可选的，接入网设备确定所述N个RRU的遍历顺序之后，也可以将所述N个RRU按照遍历的顺序编号，然后可以将编号为偶数的RRU的天线端口的逻辑端口号配置为0和1，将编号为奇数的RRU的天线端口的逻辑端口号配置为2和3，从而完成天线端口的配置。同时接入网设备也可以将编号为偶数的RRU的传输模式设置为TM4、将编号为奇数的RRU的传输模式设置为TM9。当然，接入网设备也可以将编号为偶数的RRU的天线端口的逻辑端口号配置为2和3、将编号为奇数的RRU的天线端口的逻辑端口号配置为0和1。
需要说明的是，天线端口的逻辑端口号配置相同的RRU之间进行非相干联合传输(Joint Transmission，JT)，天线端口的逻辑端口号配置不相同的RRU之间进行相干JT。
通过上述方法，接入网设备通过根据M个RSRP差值，确定N个RRU的遍历顺序，从而根据N个RRU的遍历顺序，将所述遍历顺序中相邻的两个RRU配置不相同的天线端口。由于根据M个RSRP差值确定出的N个RRU的遍历顺序反映了RRU之间的空间隔离度，因此配置天线端口后的所述N个RRU能够获得较多的支持4x4虚拟MIMO的小区联合区域，从而提高终端在所述N个RRU的覆盖区域内的空间复用增益，使得终端获得更高的数据传输速率。
结合前面的描述，可选的，在对N个RRU的天线端口进行配置之后，还可以对RRU的天线端口进行调整。下面以所述N个RRU的覆盖区域内包括K个小区联合区域为例进行描述，其中，每个小区联合区域为两个RRU的重叠区域形成的区域。
具体的，步骤一、接入网设备可以周期性的统计每个RRU下的终端信息；其中终端信息包括但不限于终端数量、终端信号质量等信息。
然后，步骤二、接入网设备获取K个小区联合区域中每个小区联合区域内的终端数量。
然后，步骤三、所述接入网设备确定所述K个小区联合区域内终端数量最多的P个小区联合区域，P小于或等于K；
最后，步骤四、所述接入网设备若确定所述P个小区联合区域中存在目标小区联合区域，则将所述目标小区联合区域对应的两个RRU的天线端口的逻辑端口号配置为不同；其中目标小区联合区域为对应的两个RRU的天线端口的逻辑端口号配置为相同的区域。
当然，上述步骤二和步骤三中，也可以用终端信号质量替换终端数量，在此不再赘述。
举例来说，如图3所示，为本申请实施例提供的一种网络架构示意图。图3中，RRU 1至RRU 6均为2×2天线。RRU1与RRU2配置的天线端口相同，均为0和1；RRU 3与RRU 4配置的天线端口相同，均为2和3；RRU 5与RRU 6配置的天线端口相同，均为0和1。RRU 2分别与RRU 5、RRU 6之间存在小区联合区域；RRU 3分别与RRU 1、RRU 2之间存在小区联合区域；RRU 5分别与RRU 3、RRU 4之间存在小区联合区域。
接入网设备周期性的统计每个RRU中的终端数量，当接入网设备确定RRU 2与RRU 5、RRU 6之间的小区联合区域中的终端数量均大于RRU 2与RRU 3之间的小区联合区域中的终端数量时，接入网设备可以将RRU 2的天线端口重新配置为与RRU 5、RRU 6不同的天线端口，例如配置为2和3，从而实现为更多的终端进入支持4x4虚拟MIMO的小区联合区域。当然，以上只是示例，也可以根据终端信号质量重新确定RRU的天线端口，在此不再赘述。
