所述天线拉远单元301配置有N个端口3011，所述RRU302包括M个射频通道3021，N为大于1且小于等于M的正整数，所述N个端口中的至少两个端口为不同类型的端口；
本发明实施例中，不同类型的端口对应发送不同的信号，其中，不同类型的端口具体为型号不同的端口，型号不同的端口可以支持不同频率的信号。另外，在一些可选的实施例中，不同类型的端口也可以是配置不同的端口，此处不做具体限定。
天线拉远单元是用来发射或接收电磁波的部件。无线电通信、广播、电视、 雷达、导航、电子对抗、遥感、射电天文等工程系统，凡是利用电磁波来传递信息的，都依靠天线拉远单元来进行工作。此外，在用电磁波传送能量方面，非信号的能量辐射也需要天线拉远单元。

502、根据确定的通道组对UE进行资源配置。
BBU按照UE的优先级顺序依次对UE进行资源配置。
本发明实施例中，BBU首先确定对UE进行资源配置的通道组，所述BBU根据确定的所述通道组对所述UE进行资源配置，所述通道组包括根据天线拉远单元中的N个端口所确定的第一通道组或者根据所述射频拉远单元中的M个射频通道所确定的第二通道组，所述第一通道组中包含N个第一通道，所述第二通道组中包含M个第二通道，N为大于1的正整数且小于等于M的正整数，通过第一通道组或者第二通道组都可发送多种不同的信号，从而支持MIMO技术，有效提升数据业务容量。
在图5所示实施例的基础上，进一步请参阅图6，本发明实施例中资源配置的方法的另一个实施例包括：
601、当根据第一通道组对UE进行资源配置时，获取UE在第一通道组中的N个第一通道上对应的参考信号SRS的信号功率；
由于第一通道组是根据天线拉远单元中的N个端口所确定的，即获取UE在每个端口上有对应的SRS的信号功率。
602、根据SRS的信号功率确定满足预设要求的第一通道；
当BBU判断SRS的信号功率满足预设要求时，则满足预设要求的SRS的信号功率所对应的第一通道为满足预设要求的第一通道。
例如：当BBU判断UE在任意一个第一通道上对应的SRS的信号功率满足预设要求时，则在对应的第一通道对UE进行资源配置。
或者，当BBU判断任意两个第一通道上对应的SRS的信号功率差满足预设要求，则在对应的两个第一通道上对UE进行资源配置。
603、在满足预设要求的第一通道上向所述UE配置资源。
BBU确定满足预设要求的第一通道后，根据用户优先级原则选取UE，比 如，一般语音通话的用户优先级高于网页浏览的用户优先级，选取UE后，则在满足预设要求的第一通道上向所述UE配置资源。
本发明实施例中，当根据第一通道组对UE进行资源配置时，BBU获取UE在第一通道组中的N个第一通道上对应的参考信号SRS的信号功率，BBU根据SRS的信号功率确定满足预设要求的第一通道，BBU在满足预设要求的第一通道上向所述UE配置资源。由于第一通道组中包含N个第一通道，通过N个第一通道可收发不同的信号，从而支持MIMO技术，有效提升数据业务容量。
在图6所示实施例的基础上，进一步请参阅图7，本发明实施例中资源配置的方法的另一个实施例包括：
701、当根据第二通道组对UE进行资源配置时，获取UE在第二通道组中的M个第二通道上对应的SRS的信道信息；
在本发明实施例中，利用SRS的信道信息计算UE的特征向量以及确定满足预设要求的第二通道。
702、根据SRS的信道信息计算UE的特征向量；
可选的，BBU通过奇异值分解算法SVD分解所述SRS的信号信息，计算出所述UE的特征向量，该特征向量可作为按照优先级顺序对UE进行资源配置的一个参考特征，比如：UE1和UE2的特征向量的内积小于预设门限值时，则BBU优先向UE1和UE2进行资源配置。
703、根据SRS的信道信息确定满足预设要求的第二通道；
其中，该SRS的信号信息包含信道质量指示信息和信道轶值，比如：当信道质量指示信息大于预设门限值，且信道轶值为N时，则确定该SRS的信号信息对应的第二通道为满足预设要求的第二通道。
本发明实施例中，步骤702与步骤703的先后顺序不做限定。
704、在满足预设要求的第二通道上向UE配置资源。
在一些可选的实施例中，在满足预设要求的第二通道上向UE配置资源包括：
BBU根据用户优先级原则从所述UE中选取第一UE，所述第一UE为优先级第一高的UE；
所述BBU在满足预设要求的第二通道上向所述第一UE配置资源。
在一些可选的实施例中，在满足预设要求的第二通道上向UE配置资源包括：
所述BBU根据用户优先级原则从所述UE中选取所述第二UE和第三UE，所述第二UE为优先级第一高的UE，所述第三UE为优先级第二高的UE；
所述BBU计算所述第二UE和所述第三UE的特征向量的内积；
当所述第二UE和所述第三UE的特征向量的内积小于预设门限值时，所述BBU在所述满足预设要求的第二通道上向所述第二UE和所述第三UE配置资源。
在一些可选的实施例中，在所述满足预设要求的第二通道上向所述第二UE和所述第三UE配置资源之后，所述BBU根据EZF算法对所述第二UE和第三UE的特征向量进行迫零，并将迫零后的所述第二UE和第三UE的特征向量映射到所述满足预设要求的第二通道上。
本发明实施例中，当根据第二通道组对UE进行资源配置时，BBU获取UE在第二通道组中的M个第二通道上对应的SRS的信道信息，BBU根据SRS的信道信息计算UE的特征向量，BBU根据SRS的信号信息确定满足预设要求的第二通道，BBU在满足预设要求的第二通道上向UE配置资源，由于第二通道组中包含M个第二通道，通过M个第二通道可收发不同的信号，从而支持MIMO技术，有效提升数据业务容量。

在以上实施例的基础上，请参阅图10a‐10b和图11a‐11b，本发明实施例中网络架构的应用场景的实施例包括：
请参阅图10a‐10b，分别为一拉二网络架构的一个结构示意图和对应的网络覆盖的一个实施例示意图，其中，RRU中的射频通道RF通过馈线外接天线拉远单元，RF有2个，RRU有3个，HUB有一个，一个HUB可对应至少一个RRU，其中，图10‐a为一个RRU对应的一拉二网络架构图，且天线拉远单元中的天线分布式部署，天线有2条，分别为Ant0和Ant1，相邻的天线配置不同的端口port，为了保证当前UE的接入，相邻天线交错配置第一端口port0和第二端口port1，RRU与HUB之间连接有cat5e，BBU与HUB之间连接有光纤fiber。
当保证室内覆盖的参考信号接收功率为-105dBm以上时，根据仿真评估，现有技术中的网络架构下要求天线间距10m，本发明实施例中的一拉二网络架构下，天线发射功率为19dBm，和现有技术的网络覆盖相当时，天线间距15m，RRU间距为30m，因此，相对于现有技术，可有效减少RRU的数量，由于RRU数量减小，对应的BBU和HUB的数量相应下降，物料成本下降，同时人工成本也大幅度下降。
本发明实施例中的一拉二网络架构下，BBU对UE进行资源配置时可以以port0和port1对应的通道进行资源配置，此时可以支持双流，而现有技术中 只有一个端口，只能支持单流，一拉二网络架构下可获得单用户的空分复用增益，通过仿真评估，相比现有技术可获得30％～60％的容量增益。
一拉二网络架构下，BBU还可以通过RF对应的通道进行资源配置，如图10‐b所示，3个RRU对应的网络覆盖的一个实施例示意图，一个RRU包含2个RF，一个RF对应一个通道，3个RRU可支持6个通道，因此，获得天线的空间自由度为6，此时可进行多用户的空间复用算法，通过仿真评估，相比现有技术可获得300％以上的容量增益。
请参阅图11a-11b，分别为一拉四网络架构的一个结构示意图和对应的网络覆盖的一个实施例示意图，RRU中的射频通道RF通过馈线外接天线拉远单元，RF有2个，RRU有2个，HUB有一个，一个HUB可对应至少一个RRU，其中，图11-a为一个RRU对应的一拉四网络架构图，且天线拉远单元中的天线分布式部署，天线有4条，分别为Ant0，Ant1，Ant2，Ant3，功分器将天线分成两路，分成两路的天线配置不同的端口port，为了保证当前UE的接入，分成两路的天线交错配置第一端口port0和第二端口port1，RRU与HUB之间连接有cat5e，BBU与HUB之间连接有光纤fiber。
由于功分器使得两根天线共享一份功率，每个天线的功率减半，考虑到线损，每个天线功率由19dBm降低为15dBm；为了保证和原来相同的覆盖，经仿真评估，天线间距为10m，此时两个RRU间距为40m，因此，相对于现有技术，可有效减少RRU的数量，由于RRU数量减小，对应的BBU和HUB的数量相应下降，物料成本下降，同时人工成本大幅度下降。
本发明实施例中的一拉四网络架构下，BBU对UE进行资源配置时可以以port0和port1对应的通道进行资源配置，此时可以支持双流，而现有技术中只有一个端口，只能支持单流，一拉二网络架构下可获得单用户的空分复用增益，通过仿真评估，相比现有技术可获得30％～60％的容量增益。
一拉四网络架构下，BBU还可以通过RF对应的通道进行资源配置，如图11-b所示，2个RRU对应的网络覆盖的一个实施例示意图，一个RRU包含2个RF，一个RF对应一个通道，2个RRU可支持4个通道，因此，获得天线的空间自由度为4，此时可进行多用户的空间复用算法，通过仿真评估，相比DAS可 获得200％以上的容量增益。
