Description

一种传输上行信号的方法、基站及系统 技术领域
本申请涉及通信技术领域，尤其涉及一种传输上行信号的方法、基站及系统。
背景技术
在现有通信系统中，下行链路上的基站与上行链路上的终端的发射功率具有相当大的差异，基站可以以几十瓦或上百瓦的功率进行发射，而终端的发射功率通常仅在毫瓦级。从而导致上行的覆盖比下行的覆盖差。现存通信系统一般工作在2.6GHz以下频段(sub2.6G)，新部署的通信系统一般工作在更高的频段，例如3.5GHz。在3.5GHz和sub2.6GHz共站的通信系统中，为了保证3.5GHz频段的上行覆盖，目前的解决方案是将高频段上行覆盖不到的用户的上行业务在低频频段传输，这种上下行工作于不同频段的方式称为上下行解耦。
以3.5GHz和1.8GHz频点共站覆盖为例：在高频的上行覆盖差区域，3.5GHz频段的上行覆盖范围小于3.5GHz频段的上行覆盖，此时用户上行业务在1.8GHz频段上传输，上行覆盖可以扩大到1.8GHz的上行覆盖范围，从而解决上行覆盖差于下行的问题。但是3.5G系统覆盖受限用户上行业务移到1.8GHz后，虽然增加了上行覆盖，但还不能与3.5G的下行覆盖完全拉齐。且由于1.8GHz频段用户增多，业务量相应增加，导致1.8GHz频段上的资源块(Resource Block，RB)利用率升高，1.8GHz频段上小区间干扰随之升高，这将降低1.8GHz网络的上行性能。

具体实施方式
下面结合本申请实施例中的附图对本申请的实施例进行描述。
本申请的说明书和权利要求书及上述附图中的术语“包括”和“具有”以及它们任何变形，意图在于覆盖不排他的包含。例如包含了一系列步骤或单元的过程、方法、系统、产品或设备没有限定于已列出的步骤或单元，而是可选地还包括没有列出的步骤或单元，或可选地还包括对于这些过程、方法、产品或设备固有的其它步骤或单元。
请参见图1，图1为本申请实施例提供的一种传输上行信号的系统架构示意图；该系统架构包括基站和终端。
基站可以包括但不限于：演进型节点B(evolved Node B，eNB)、无线网络控制器(radio network controller，RNC)、节点B(Node B，NB)、基站控制器(Base Station Controller，BSC)、基站收发台(Base Transceiver Station,BTS)、家庭基站(例如，Home evolved NodeB，或Home Node B，HNB)等。
终端，又称之为用户设备(User Equipment，UE)，是一种向用户提供语音和/或数据连通性的设备，例如，具有无线连接功能的手机、平板电脑、可穿戴设备等。
在本申请实施例中，基站的组成可以包含有源天线单元(Active Antenna Unit，AAU)和与高频段对应的第一基带处理单元(BaseBand Unit，BBU)。在多个频段组网下，采用AAU方案后，可集成两个或以上不同频段的射频单元以及对应的天线，从而形成AAU。在本申请的实施例中，为了便于描述，以两个频段为例进行说明，本领域技术人员应当理解，两个以上的频段也可以采用本申请中的方法及基站进行信号传输，本申请实施例不作任何限定。如图1所示，AAU集成了高频段3.5G的阵列天线和低频段sub2.6G的阵列天线。当 终端位于3.5G上行覆盖的范围内时，可以直接通过3.5G频段与基站进行上行信号传输，当终端位于sub2.6G上行覆盖的范围内时，终端可以直接通过sub2.6G频段与基站进行上行信号传输，当终端位于3.5G上行覆盖范围之外的3.5G下行覆盖范围内时，此时将无法使用3.5G频段进行上行型号传输，此时可以选择sub2.6G频段进行上行信号的传输。有源天线单元由于集成了低频段sub2.6G的阵列天线，因此可以直接接收该上行信号并发送至3.5G频段对应的第一基带处理单元进行信号解调，得到上行业务的数据。
下面结合图2-图5对本申请传输上行信号的方法进行详细描述。
请参见图2，图2为本申请实施例提供的一种传输上行信号的方法的流程示意图；具体包括如下步骤：
S201、基站通过有源天线单元接收终端在第一频段发送的第一上行信号。
其中，作为一种可能的场景，所述终端可以处于第二频段上行覆盖范围之外或第二频段上行覆盖边缘。
可选地，所述终端可以处于第二频段的下行覆盖范围之内和第一频段的上行覆盖范围之内，也可以处于第二频段的下行覆盖之外而处于第一频段的上行覆盖范围之内，此时，终端都可以使用第一频段来发送第一上行信号，本申请实施例不作任何限定。
其中，所述基站的有源天线单元包括第一频段对应的第一阵列天线和第二频段对应的第二阵列天线，所述第一频段低于所述第二频段。可选地，所述第一频段可以为低于第一频段阈值的频段，所述第二频段可以为高于第二频段阈值的频段。而第一频段阈值小于第二频段阈值。基于现有通信系统使用的频段，第一频段可视为低频段如sub2.6G频段，第二频段可视为高频段如新空口(New Radio，NR)中使用的3.5G或以上频段。需要说明的是，随着通信技术的不断发展和演进，高频段和低频段的频段范围将可能发生变化，此时第一频段阈值和第二频段阈值的取值也可以随之变化，本申请实施例不作任何限定。
有源天线单元的具体实现，可以参见图3，图3为本申请实施例提供的一种AAU中天线布局的示意图。如图所示，水平方向表示3.5G阵列天线的水平端口，竖直方向表示3.5G阵列天线的垂直端口。3.5G阵列天线的每个收发通道对应一个单天线，一般一个或多个振子组成一个单天线。例如在3.5G阵列天线中，每个单天线在垂直方向上对应3个振子。为了节省天线体积，在3.5G阵列天线中采用双极化天线。双极化天线是一种新型天线技术，组合了+45°和-45°两副极化方向相互正交的天线并同时工作在收发双工模式下。即一个双极化天线对应两个单天线(即对应两个收发通道)。如图3所示，小x表示3.5G阵列天线中的振子，因此一共包括12行8列共96个振子。因此在每列有12/3共4个双极化天线，8列则有8*4共32个双极化天线，对应64个收发通道。大X以及小圆点表示sub2.6的振子。sub2.6G振子可以插放在3.5G振子排列的空隙处，位于3.5G振子的间隙之间；sub2.6G振子的个数不限，位于3.5G振子之间的sub2.6G振子可以是一个或者多个。
通过在高频大规模多输入多输出系统的AAU上通过插花布局和走线来放置低频段的阵列天线(包括多个振子)，例如，可以将sub2.6G的阵列天线布局在3.5G的阵列天线间隙中间，这样，AAU的体积和成本变化不大，利于兼容原通信系统和降低成本。当然，也可以将第一阵列天线的振子设置在第二阵列天线周围的任意方向，可以接收第一上行信号即可，本申请实施例不作任何限定。
可选地，将低频段的第一频段阵列天线与高频段的第二频段阵列天线集成布局之后，低频段的第一频段阵列天线与对应的接收通道连接，低频段的第一阵列天线的接收通道可以包括滤波器、小信号放大器、模数转换器等，可实现将空口的电磁波信号转换为数字信号，以供第一基带处理单元进行信号解调。需要说明的是，此处的低频段的第一阵列天线可以实现接收信号的功能即可。接收通道成本较低，相比天线支持完整的发射和接收功能，可显著降低接收低频段信号的成本。当然，如果成本和天线尺寸设计允许，也可以将低频信号的发射通道集成在AAU中。本申请实施例不作任何限定。
S202、所述基站将所述第一上行信号通过通用公共无线电接口(Common Public Radio Interface，CPRI)或增强的通用公共无线电接口(enhanced Common Public Radio Interface，eCPRI)发送至所述第二频段对应的第一基带处理单元进行解调。
当AAU接收到第一上行信息之后，便可以通过与第二频段即高频段对应的第一基带处理单元进行解调，从而获取到上行业务的数据。
可选地，所述增强的通用公共无线电接口或通用公共无线电接口为所述第一阵列天线独立使用。即在高频段和低频段共AAU的系统中，可以为低频段的上行信号传输配置独立的接口和传输线路。例如在NR 3.5G和sub2.6G共AAU的系统中，由于NR 3.5G的空口带宽大、天线数多，传输AAU到第一BBU的数据对CPRI/eCPRI资源需求大，如果较多的低频段上行业务转移到高频段传输和处理，将会占用高频段的CPRI/eCPRI资源。因此，配置独立的Sub2.6G CPRI/eCPRI接口可以避免占用高频段的CPRI/eCPRI资源。增加了AAU和第一BBU之间的传输容量，实现了sub2.6G接收数据的独立传输，提升了上行业务的传输性能。
可选地，可以通过在AAU上安装独立的sub2.6G光纤模块来实现，该独立的光纤模块可以将sub2.6G的第一上行信号通过独立的光纤传输到第一BBU。
通过在有源天线单元的高频段阵列天线中布局低频段阵列天线，增加了基站的上行信号传输通路，将高频段的上行业务通过低频段传输，可以扩大基站的上行覆盖，通过合理配置高低频段的共站配合，使得上下行覆盖对齐，提升了系统的上行性能。
请一并参见图4和图5，图4为本申请实施例提供的另一种传输上行信号的方法的流程示意图；图5为图4所述方法对应的上行信号传输示意图；在本实施例中，步骤S401-S402与步骤S201-S202相同，此处不再赘述。在步骤S402之后，还包括：
S403、所述基站通过所述第一频段对应的射频拉远单元(Radio Remote Unit，RRU)接收所述终端在所述第一频段发送的第二上行信号。
其中，第二上行信号与第一上行信号可以为同一个上行信号，即同一个终端针对同一个上行业务在同一时间发送的上行信号。基站可以通过AAU和RRU分别进行接收，即第一上行信号可以被AAU接收，第二上行信号可以被RRU接收；
或者，第二上行信号也可以为发送第一上行信号的同一个终端，针对同一个上行业务在相同或不同时间发送的，与所述第一上行信号解调相关的信息。基站可以通过AAU和RRU分别进行接收，即第一上行信号可以被AAU接收，第二上行信号可以被RRU接收。
S404、所述基站通过所述射频拉远单元将所述第二上行信号发送至与所述第一频段对 应的第二基带处理单元。
S405、所述基站通过所述第二基带处理单元将所述第二上行信号发送至所述第一基带处理单元。
S406、所述基站通过所述第一基带处理单元对所述第一上行信号和所述第二上行信号进行联合解调。
多天线的联合解调可以是将所有天线接收的数据按照一体多天线解调算法进行解调，或者也可以是传输上行信号解调过程的某节点量(如频域数据、多天线合并后的接收信号)与上行信号进行协作解调。
如图5所示，实现箭头为第一上行信号的传输路线，虚线箭头为第二上行信号的传输路线，射频单元为sub2.6G频段对应的RRU，第二基带处理单元为sub2.6G频段对应的BBU。第一上行信号发送至AAU之后，再发送至第一BBU，第二上行信号经过RRU和第二BBU之后，也传输至第一BBU，由第一BBU对AAU中的sub2.6G阵列天线以及RRU中的sub2.6G天线收到的信号进行多天线联合解调。
需要说明的是，本申请所述的联合解调同样可以适用于其他独立的RRU接收到的sub2.6G上行信号与LTE sub2.6G接收的上行信号进行联合解调，本申请实施例不作任何限定。
结合图2，图4和图5的实施方式，以网络中在同站址上部署3.5G NR和sub2.6G系统，sub2.6G频段上已有2发2收(2T2R)的长期演进(Long Term Evolution，LTE)的系统场景为例。3.5G NR系统的Massive MIMO AAU中通过插花布局部署sub2.6G接收的阵列天线，参见图3所示，该AAU中3.5G阵列天线的每个收发通道对应一个单天线，每个单天线在垂直方向上对应3个振子。为了节省天线体积，在3.5G阵列天线中采用双极化天线。双极化天线是一种新型天线技术，组合了+45°和-45°两副极化方向相互正交的天线并同时工作在收发双工模式下。即一个双极化天线对应两个单天线(即对应两个收发通道)。如图3所示，小x表示3.5G阵列天线中的振子，因此一共包括12行8列共96个振子。因此在每列有12/3共4个双极化天线，8列则有8*4共32个双极化天线，对应64个收发通道。sub2.6G振子插放在3.5G振子空隙处，如图3所示，每间隔两列插放sub2.6G振子，并且sub2.6G单天线只与其对应的接收通道连接，即只具有接收通道的功能，sub2.6G阵列天线包括8个接收通道，每个接收通道对应一个单天线，每个单天线在垂直方向上对应8个振子，(如图所示4列圆圈振子，每列双极化，共8列)。
当3.5G NR用户位于3.5G频段上行覆盖之外且在3.5G下行覆盖之内时，将3.5G NR用户上行业务在sub2.6G频段上进行发送。
AAU上的sub2.6G的8个接收天线(8R)即仅具备接收信号功能的单天线接收NR系统在sub2.6G做上行业务的第一上行信号，并由AAU上的sub2.6G专用光纤模块接口，通过eCPRI/CPRI将8R接收信号传输给NR的第一BBU。
同时，LTE sub2.6G系统及与sub2.6G频段对应的RRU(包括2R)也接收到了用户在Sub2.6G发上行业务的第二上行信号，RRU接收的信号通过CPRI传输到该系统的LTE的第二BBU。
将第二BBU收到的sub2.6G LTE的2R天线数据通过板间传输传到NR的第一BBU，第 一BBU将收到的10R(第二BBU的2R+第一BBU sub2.6G的8R)进行多天线联合解调，解调出NR系统在sub2.6G的上行业务数据和sub2.6G LTE的上行业务数据。
通过在AAU上布局3.5G频段阵列天线和sub2.6G频段阵列天线，从而可以使得NR系统的上行覆盖扩大到sub2.6GHz 2R+8R的上行覆盖范围，使得3.5G频段和sub2.6G频段共站建设并达到同覆盖。且在共站建设时，由于sub2.6G的LTE由于使用了2R+8R，从而可以提升sub2.6G的上行频谱效率，获得多天线的空分复用增益，用户感知吞吐率提升。
请参照图6，为本申请实施例提供的一种基站的组成示意图；可包括：
有源天线单元100，用于接收终端在第一频段发送的第一上行信号，其中，所述终端处于第二频段上行覆盖范围之外；将所述第一上行信号通过通用公共无线电接口或增强的通用公共无线电接口发送至所述第二频段对应的第一基带处理单元200；
所述第一基带处理单元200，用于对接收到的所述第一上行信号进行解调；
其中，所述基站的有源天线单元100包括第一频段对应的第一阵列天线101和第二频段对应的第二阵列天线102，所述第一频段低于所述第二频段。
可选地，所述第一阵列天线101的振子位于所述第二阵列天线102的振子的间隙中。由于第一阵列天线为较低的第一频段对应的阵列天线，第二阵列天线为较高的第二频段对应的阵列天线，因此第二阵列天线的振子之间的空隙较大，可以将第一阵列天线的振子插花布局在第二阵列天线的振子的空隙当中，从而可以减少有源天线单元的体积，降低设计成本。当然，也可以将第一阵列天线的振子设置在第二阵列天线周围的任意方向，可以接收第一上行信号即可，本申请实施例不作任何限定。
可选地，所述通用公共无线电接口或增强的通用公共无线电接口为所述第一阵列天线101独立使用。在具体实现时，可以为第一阵列天线配置独立的光纤模块用于传输信号。从而减少对高频的第二阵列天线的传输接口和传输通道的占用，提升传输效率。
可选地，第一阵列天线可以包括发射通道和接收通道，在本申请实施例中，第一阵列天线的接收通道可以包括滤波器、小信号放大器、模数转换器等，可实现将空口的电磁波信号转换为数字信号，以供第一基带处理单元进行信号解调。需要说明的是，此处的低频段的第一阵列天线可以实现接收信号的功能即可。因此，可以去掉第一阵列天线的发射通道，保留接收通道，从而可显著AAU降低接收低频段信号的成本。

第二基带处理单元400，用于将所述第二上行信号发送至所述第一基带处理单元200；
所述第一基带处理单元200还用于对所述第一上行信号和所述第二上行信号进行联合解调。
通过联合解调，可以提升低频段的上行频谱效率，获得多天线的空分复用增益，提升 用户感知的吞吐率。
请参照图8，为本申请实施例提供的另一种基站的组成示意图；如图8所示，该基站可以包括处理器110、存储器120和总线130。处理器110和存储器120通过总线130连接，该存储器120用于存储指令，该处理器110用于执行该存储器120存储的指令，以实现如上图2-图4对应的方法中的步骤。
进一步的，该基站还可以包括、输入口140和输出口150。其中，处理器110、存储器120、输入口140和输出口150可以通过总线130相连。
处理器110用于执行该存储器120存储的指令，以控制输入口140接收信号，并控制输出口150发送信号，完成上述方法中基站执行的步骤。其中，输入口140和输出口150可以为相同或者不同的物理实体。为相同的物理实体时，可以统称为输入输出口。所述存储器120可以集成在所述处理器110中，也可以与所述处理器110分开设置。
