具体实施方式
随着无线通信技术的发展，移动互联网流量到2020年将会增长1000倍。第五代蜂窝网络通信被指能够带来1000倍的系统容量提升，并且能提供许多新特性，比如支持海量低功耗设备接入，扩大覆盖率，提高可靠性，降低延迟等。这些目标需要采用一些新的技 术来实现，比如大规模天线(massiveMIMO)技术，全双工技术，协作中继技术，毫米波通信和设备到设备通信(device-to-device，D2D)等。其中多输入多输出(multiple-inputmultiple-output，MIMO)技术，由于能够显著地提升通信系统的可靠性和容量，已经被成功的应用在多种通信标准中。
但是，大规模MIMO技术通过在网络设备配置大量的天线振子，使得系统的空间自由度得到提升，从而能有效地提升系统容量以及能量效率和频谱效率。由于大规模MIMO系统空间自由度的提升，可以大大降低系统终端的信号处理复杂度，并且在网络设备端只需要布置简单的线性信号处理算法就能够达到减小或消除小区内用户间干扰、小区间干扰、信道估计误差以及噪声的影响。
以下结合图3所示对申请所示的通信系统的具体结构进行示例性说明：
本实施例所示的通信系统包括用户设备301以及网络设备32，本实施例所示的通信系统以应用至第五代移动通信技术(5th-Generation，5G)中为例进行示例性说明：
本实施例所示的所述网络设备32具体包括基带处理单元BBU321、至少一个有源模块322以及天线阵列323。其中，图3以所述网络设备32包括有一个有源模块322为例进行示例性说明，在具体应用中，所述网络设备32可包括有多个所述有源模块322，所述有源模块322的具体数量在本实施例中不做赘述。
本实施例所示的所述BBU321用于进行编码、复用、调制和扩频等基带处理功能，所述BBU321与所述有源模块322通过光纤连接，本实施例所示的所述有源模块322可为射频拉远单元(remote radio unit，RRU)，所述有源模块322可具体包括中频模块、收发信机模块、功放和滤波模块。所述中频模块用于光传输的调制解调、数字上下变频、A/D转换等；收发信机模块完成中频信号到射频信号的变换；再经过功放和滤波模块，将射频信号通过天线阵列发射出去。本实施例对所述有源模块所支持的通道数量不做限定，例如，所述有源模块可支持8通道、16通道或32通道等。
具体的，在下行方向：光纤从BBU321直接连到有源模块322，BBU321和有源模块322之间传输的是基带数字信号，这样网络设备可以控制某个用户的信号从指定的有源模块322通道发射出去，这样可以大大降低用户间的干扰。
在上行方向：用户设备的信号被距离最近的有源模块322的通道收到，然后从这个通道经过光纤传到网络设备，这样也可以大大降低不同通道上用户设备之间的干扰。
与图1所示的现有技术不同的是，本实施例所示的所述有源模块322与所述天线阵列323呈解耦结构设置，即在所述网络设备侧，所述有源模块322与所述天线阵列323为分开设置的。
本实施例所示的所述天线阵列323可为大规模天线阵列，其中，大规模天线阵列是基于多用户波束成形的原理，在网络设备侧布置的大量天线振子，对大量天线振子调制各自的波束，通过空间信号隔离，在同一频率资源上同时传输几十条信号。这种对空间资源的充分挖掘，可以有效利用宝贵而稀缺的频带资源，并且几十倍地提升网络容量。
其中，波束成形(Beamforming)是指，从网络设备方面看，利用数字信号处理产生的叠加效果就如同完成了网络设备端虚拟天线方向图的构造。通过这一技术，网络设备所发 射的能量可以汇集到特定用户设备所在位置，而不向其他方向扩散，并且网络设备可以通过监测用户设备的信号，对其进行实时跟踪，使最佳发射方向跟随用户设备的移动，保证在任何时候用户设备接收点的电磁波信号都处于叠加状态。可见，大规模天线阵列的应用不单可以大幅度提升网络容量和用户体验，也将对通信行业产成深远的影响。

为实现所述天线阵列单元和所述第二有源模块的连接，则所述网络设备还包括用于连接所述第三端口1403的连接件，该连接件的具体结构，请参见上述所示，具体不做赘述；
所述第三端口1403与所述第二端口的连接的具体方式，请详见上述所示的第一端口与所述第二端口连接的具体方式，具体不做赘述。
可见，采用本实施例所示的网络设备，所述密封套1502可对所述密封套1502内部的N个电缆进行安装，以避免N个电缆接触到水、灰尘等，有效的提升了电缆的使用寿命，而且在将所述第一端口连接到所述第二端口上时，可一次性的实现N个电缆的第一接头与N个第二接头连接，提升了将所述第一有源模块与所述第一辐射单元连接的效率，同样的，在将所述第二端口连接到所述第三端口上时，可一次性的实现N个电缆的第一接头与N个第二接头连接，提升了将所述第二有源模块与所述第二辐射单元连接的效率。
可选的，采用本实施例所示的网络设备还可实现频段的扩展，具体的，所述网络设备所包括的天线阵列的数量为多个，且不同的天线阵列所支持的频段范围不同，例如，以图17所示为例，所述网络设备包括有第一天线阵列1701以及第二天线阵列1702，所述第一天线阵列1701以及所述第二天线阵列1702具体结构的说明，请详见上述所示，具体不做赘述。
具体的，若所述网络设备包括有多个天线阵列，为实现全向覆盖且不同的天线振子之间在覆盖范围上互不遮挡，则多个天线阵列沿所述天线阵列的轴向，依次排列设置，本实施例对所述网络设备所包括的每一天线阵列所支持的频段不做限定。
以图17所示为例，所述网络设备所包括的第一天线阵列1701可为支持3.5G频段的辐射单元和支持4.5G频段的辐射单元共用的设计，则在初期创建网络设备时，若确定当前的网络环境需要的支持3.5G频段，则可在所述网络设备上安装第一有源模块，通过该第一有源模块连接所有支持3.5G频段的辐射单元，而后续根据网络的使用情况，如确定出后续网络环境需要继续支持4.5G频段，则无需安装新的网络设备，只要在该网络设备上安装第二有源模块，通过该第二有源模块连接所有支持4.5G频段的辐射单元；再如，如确定出后续网络环境需要继续支持2.6G频段，但已安装在网络设备上的第一天线阵列1701不支持2.6G频段，则可将支持2.6G频段的第二天线阵列1702安装在当前的网络设备，可见，本实施例所示的网络设备，可通过增加有源模块或通过增加天线阵列的方式实现网络设备所支持的频点的扩展。
以下对本实施例所示的网络设备的有益效果进行说明：
结合图1所示的现有技术可知，在现有技术的方案中，天线阵列和有源模块是一体化设置，在小区容量提高时，需要增加网络设备的数量，而本实施例所示的方案中，因所述网络设备所包括的天线阵列和有源模块之间采用的是解耦设计的方案，则所述天线阵列以及所述有源模块可独立进行演进，也可根据需要对所述天线阵列或所述有源模块单独进行 更换，例如，若原先安装在网络设备上的有源模块的功率过低，不能够支持当前的通信需求，则可将支持更高功率的有源模块替换原先安装在所述网络设备上的功率过低的有源模块，增加了网络设备的应用场景，提升了网络设备适用网络环境的自由度。
又如，在初期创建网络设备时，所述网络设备可仅包括所述第一有源模块，而且网络设备后续的使用过程中，业务量提升时，初期创建网络设备所包括的第一有源模块不能够支持后续所提升的业务量，则可在所述网络设备上增加所述第二有源模块，以扩充所述网络设备所支持的网络容量，从而使得网络设备能够支持更大容量的业务量。
例如，在初期创建网络设备时，若将网络设备应用于郊区的场景中，则可在网络设备上仅安装第一有源模块即可满足当前的网络容量，若郊区的业务量后续有大幅度的提升，则采用本实施例所示的方案，无需重新创建网络设备，而仅需要在当前的网络设备上安装第二有源模块，即可实现网络扩容。
以上所述，以上实施例仅用以说明本发明的技术方案，而非对其限制；尽管参照前述实施例对本发明进行了详细的说明，本领域的普通技术人员应当理解：其依然可以对前述各实施例所记载的技术方案进行修改，或者对其中部分技术特征进行等同替换；而这些修改或者替换，并不使相应技术方案的本质脱离本发明各实施例技术方案的精神和范围。
