技术领域
本公开实施例涉及通信领域，具体而言，涉及一种基站。
背景技术
图1是根据相关技术中RRU基站组网的示意图，如图1所示，传统的射频拉远单元(Radio Remote Unit，简称为RRU)基站三扇区组网方式将三个多发多模基站和三个天线呈120度分布，实现三扇区全覆盖，每个扇区通过电缆连接一个多发多模基站。这种组网方式站点需要提供三路电源给三个基站，即需要提供三路电源线，同时需要三对光纤，有些场景每扇区还需要配置一个独立的室外防雷箱。采用新型共享基站，可以大大减少电源端子，光纤数量要求，这样大大降低了配套成本和施工难度，大幅提升部署的便利性和速度。同时这种传统的连接方式比较固定，无论哪个扇区覆盖的用户量增加还是减少，都是通过一个固定的4TR(收发，Transmit Receive)的RRU来实现信号覆盖，当用户减少时，存在一定的资源浪费。随着5G基站的大面积覆盖，5G基站的需求激增，传统的RRU基站的组网方式对RRU的需求数量庞大，同时安装多个RRU对站点选择和施工也带来很大挑战也存在难度。
针对相关技术中RRU基站的组网方式，用户减少时存在一定的资源浪费，且对RRU的需求数量庞大，同时安装多个RRU对站点选择和施工存在较大难度的问题，尚未提出解决方案。

具体实施方式
下文中将参考附图并结合实施例来详细说明本公开的实施例。
需要说明的是，本公开的说明书和权利要求书及上述附图中的术语“第一”、“第二”等是用于区别类似的对象，而不必用于描述特定的顺序或先后次序。
本公开实施例提供了一种基站，图2是根据本公开实施例的基站的框图，如图2所示，所述基站包括：多个收发通道，该多个收发通道包括至少3个TR固定通道与至少1个TR共享通道，至少3个TR固定通道分别连接至少3个扇区，每个扇区对应至少1个TR固定通道，至少1个TR共享通道共享给至少3个扇区。
在一实施例中，在TR共享通道为1个的情况下，TR共享通道用于监测至少3个扇区的物理资源块PRB的利用率，配置给所述最大利用率大于第一预设阈值的的目标扇区；在TR共享通道为大于1个的情况下，TR共享通道用于监测至少3个扇区的物理资源块PRB的利用率，配置给利用率大于第二预设阈值的至少一个目标扇区，该第一、第二预设阈值可以根据实际情况设置，例如可以设置为50％，55％、60％等，第一预设阈值与第二预设阈值可以相同也可以不同。
在一实施例中，目标扇区还可以被劈裂成至少第一扇区与第二扇区；目标扇区对应的至少1个TR固定通道，用于配置给第一扇区；目标扇区对应的至少1个TR共享通道，用于配置给第二扇区，其他扇区也可以被劈裂成至少两个扇区，TR固定通道配置给其中的部分扇区，TR共享通道配置给其中的除该部分扇区之外的其他扇区。
图3是根据本公开示例性实施例的基站的框图，如图3所示，所述基站还包括通道选择组件，至少1个TR共享通道与通道选择组件连接；TR共享通道，用于通过该通道选择组件配置给所述目标扇区。
在一示例性实施例中，上述的通道选择组件可以设置于基站的外部，TR共享通道与通道选择组件连接，用于通过该通道选择组件配置给目标扇区，即通过通道选择组件进行通道选择。该通道选择组件具体可以为机械传动开关。
在一实施例中，至少3个扇区中的每个扇区包括至少2个天线接口，至少2个天线接口中的至少1个天线接口与至少1个TR固定通道固定连接；至少2个天线接口中除所述至少1个天线接口之外的至少1个天线接口，用于连接至少1个TR共享通道。
本实施例中，多个收发通道中的每个通道，用于接收BBU的基带数据，对该基带数据进行处理之后通过天线发送出去；和/或，所述多个收发通道中的每个通道，接收来自天线的信号，对该信号进行处理之后发送给BBU。
在一实施例中，多个收发通道中的每个通道，还用于接收来自BBU的基带数据，对该基带数据进行载波及数字处理，得到数字信号；将该数字信号转换成模拟信号；将该模拟信号进行放大处理，得到放大后的模拟信号；对放大后的模拟信号进行滤波，得到发射信号，并 通过天线发送发射信号。
在另一实施例中，多个收发通道中的每个通道，还用于接收来自天线的信号，对信号分别进行滤波与低噪声放大处理，得到处理后的目标信号，将目标信号转换为数字信号，将转换后的数字信号发送给BBU。
下面以基站包括至少8个TR通道，覆盖三个扇区为例对本公开实施例进行详细说明。
图4是根据本实施例的共享基站系统的示意图，如图4所示，可以用一个多模基站实现传统三个基站，实现三扇区信号覆盖，通过网络优化共享基站内通道，达到简化基站工程施工难度，降低配套成本，降低基站功耗实现智能，绿色，节能的目标。
在本实施例中可以用一个8发8收的共享基站代替传统的3个4发4收基站，一个8TR的RRU包含8个TR通道，其中6个TR通道分别连接三个扇区，剩下的2TR共享给三个扇区，对外输出12个天线接口，根据不同小区的业务量进行共享调度优化网络。这种共享基站可以通过2TR通道连接每个扇区实现信号网络覆盖，同时当业务量增加时，切换增加共享2TR的通道，实现4TR一个扇区的信号覆盖。可以实现在减少RRU的前提下，完成和优化之前一样的信号覆盖。可以在共享基站内实现通道之间共享动态切换，也可以外加通道选择模块，实现基站和天线之间的通道动态分配。
图5是根据本实施例的共享基站内部实现的框图，如图5所示，由数字处理模块，数模转换模块，模数转换模块，发射模块，接收模块，滤波模块，通道选择模块和天线模块组成。
发射链路工作过程如下：数字处理模块接收来自BBU的基带数据，对基带数据进行载波及数字处理，数字处理后的信号经过数模转换模块后变成模拟信号，模拟信号经过发射模块放大等处理后给滤波模块进行滤波，滤波后的信号进入通道选择模块送给天线模块发射出去。
接收链路工作过程如下：天线模块接收到有用信号，经过通道选择模块送个响应的接收通道进行滤波处理，滤除阻塞干扰信号，然后给接收模块进行低噪声放大等处理，接收模块处理后的信号给模数转换模块输出数字信号，然后传给数字处理模块进行NCO变频，抽取，载波处理等数字处理，处理后的数字信号送给BBU进行下一步通信。
其中通道选择模块为此架构关键点，要求能承受高功率容量，高互调，高隔离，低插损的性能要求和高可靠性长时间寿命要求，同时要在基站产品应用成本必须能满足产品批量要求。由于通道选择模块在基站输出功率放大器之后，需要承受额定发射功率，对开关功率容量有较高要求，同时在空口收发合并后，为了保证发射互调落入接收带内噪声不影响接收灵敏度，要求开关的互调指标达到-150dBc左右。数字开关由于无源互调指标太差满足不了本实施例的应用，同轴开关性能和功率满足但是成本太过昂贵不能满足批量工程化应用，所以本实施例选择机械传动开关实现通道选择功能，通过机械滑动的方式实现低插损，高互调，高隔离，高功率容量的要求，并且成本低，易工程化应用。
图6是根据本实施例的四发三扇区的共享基站电路设计的框图一，图7是根据本实施例的四发三扇区的共享基站电路设计的框图二，如图6和7所示，为一个8发8收基站，内部集成8通道切换12通道的电路，对外输出12个天线接口，与四通道三扇区天线对接，TR1-TR8代表RRU中的通道数量，ANT1-ANT12代表天线名称。
RRU内部的TR1-2通道对应扇区一，TR3-4通道对应扇区二，TR5-6通道对应扇区三，TR7-8通道为共享通道。
内部集成通道切换电路，将TR7和TR8通道根据三个扇区业务量大小分别对应到不同的扇区 上。根据不同扇区的小区的业务量，控制开关切换将共享基站的通道切换到业务量最大的小区对应的天线扇区。此开关选择模块要能承受额定发射功率，同时满足系统无源互调指标需求。
本实施例中的开关组件(即上述的通道选择组件)采用一种机械传动开关，该开关可以响应基站工作的所有频段，无源互调指标高，同时可以承受大功率信号，满足系统应用需求。该开关实现将TRX7和TRX8的信号选择到n个扇区，相当于两个n选一开关，其中n为扇区个数。如图6所示，该开关组件可以是集成在基站内部。如图7所示，也可以在基站外以一个独立的模块外接，灵活配置。
图8是根据本实施例的扇区劈裂的示意图，如图8所示，除了支持8通道三扇区以外，还支持8通道四扇区等其他组网应用，支持将其中至少一个扇区劈裂成为两个覆盖60°范围的扇区，2个通道支持其中一个扇区，共享通道支持另外一个扇区。
另外，本实施例不局限于8通道三扇区这种组网方式，还包括更多通道和对应更多扇区的组网方式，图9是根据本实施例的10通道三扇区组网方式的框图，如图9所示，10通道三扇区的组网方式，RRU包含6个固定通道和4个共享通道，其中每个扇区有两个固定的通道，4个共享通道通过监控每个小区的PRB的利用率来分配给不同的扇区。同时也支持将某个扇区劈裂成为更多扇区，将共享通道任意配置。图10是根据本实施例的10通道四扇区组网方式的框图，如图10所示，用一个8TR共享基站实现4TR四扇区，其中，TR1-TR8两个一组分别为四个扇区的公共通道，TR9和TR10为共享通道通过四选一开关选择四个扇区，实现4通道4扇区覆盖。
下面以一个8通道基站覆盖4通道三扇区为例，说明名单扇区单小区下共享基站的工作流程，图11是根据本实施例的共享基站智能分配的流程图，如图11所示，包括：
步骤S1101，BBU建立3个2TR的小区，分别对应3个扇区。
步骤S1102，BBU实时监测每个小区的PRB利用率，记为A、B、C；
步骤S1103，判断A、B、C中的最大值是否大于预设阈值，在判断结果为是的情况下，执行步骤S1104，否则结束；
步骤S1104，将利用率最大的小区配置成4TR小区。
若预设阈值为50％，当三个小区都小于或等于50％时，表示此时业务量低，则不需要扩展4TR小区达到节能目标。当三个小区PRB利用率大于50％，则将最大PRB利用率的小区配置成4TR小区。
本实施例中的具体示例可以参考上述实施例及示例性实施方式中所描述的示例，本实施例在此不再赘述。
显然，本领域的技术人员应该明白，上述的本公开的各模块或各步骤可以用通用的计算装置来实现，它们可以集中在单个的计算装置上，或者分布在多个计算装置所组成的网络上，它们可以用计算装置可执行的程序代码来实现，从而，可以将它们存储在存储装置中由计算装置来执行，并且在某些情况下，可以以不同于此处的顺序执行所示出或描述的步骤，或者将它们分别制作成各个集成电路模块，或者将它们中的多个模块或步骤制作成单个集成电路模块来实现。这样，本公开不限制于任何特定的硬件和软件结合。
