Description
本申请要求在2014年10月29日提交中国专利局、申请号为201410594143.X、发明名称为一种分配频谱的方法和设备的中国专利申请的优先权，其全部内容通过引用结合在本申请中。
本发明涉及无线通信技术领域，特别涉及一种分配频谱的方法和设备。
5G提出了未来1000倍甚至更高的流量增长目标，这就需要寻求更多的无线移动通信频段，以满足2020年及以后无线移动通信市场发展需要。ITU-R(ITU-Radio communications sector，国际电信联盟无线电通信组)预测我国2020年移动通信频率需求量为：1490～1810MHz，而目前分配的可用频率通常在几百MHz量级。
目前无线电监管主要采用固定频率分配政策，一方面新的频率需求不断涌现，无线系统很难分配得到所需的频谱资源，另一方面已分配的频谱资源利用率不高，存在高度的频率使用不均衡性。有必要开展更灵活的频率使用技术以及政策的研究，提高频率利用的效率。
频谱共享技术是一种具有前景的智能频率利用方式，除技术上需要持续不断的研究和完善外，还需要考虑无线电频率使用以及监管规则的调整与变化。
现今的频谱使用现状是未来需求远超可用资源，频谱共享与新规划的频谱相结合，才能更有效保障满足未来的高频谱效率和高速率的需求。多个运营商由于用户在不同区域、时间上分布不均匀，导致不同运营商的接入网络的负载在时间、空间上存在差异，从而对频谱的需求存在差异。静态的频谱分配策略使不同运营商的接入网络不能根据网络负载的改变而动态的调整占用的频谱资源，从而造成了频谱资源不能被充分利用和频谱过饱和利用。
在现有技术中，尚没有针对多运营商频谱共享的方案。而对于多系统(例如运营商内的多RAT(Radio Access Type，无线接入类型))之间频谱共享，以及认知无线电系统与其它主系统的频谱共享，基本上是基于访问数据库或者物理层频谱感知技术将空闲频谱资源在系统间实现共享使用，而这样的方案无法满足多运营商频谱共享。
综上所述，目前还没有一种针对多运营商频谱共享场景进行频谱分配的方案。

在实施中，本发明实施例的频谱分配设备可以是集中式架构中的高级频谱管理单元，或者叫中心管理单元，或者叫做数据库设备，该设备具备连接到运营商现有设备上(例如网管设备)的功能。
下面结合说明书附图对本发明实施例作进一步详细描述。
如图1A所示，本发明实施例一分配频谱的系统包括：频谱分配设备10和基站20。
频谱分配设备10，用于确定已进行频谱分配的目标基站与所述目标基站的每个需要进行频谱分配的相邻基站之间的距离；根据目标基站与每个所述相邻基站之间的距离，确定每个所述相邻基站相对于所述目标基站的可用频谱，并根据每个所述相邻基站的可用频谱，确定每个所述相邻基站相对于所
述目标基站的预分配频谱；针对一个所述相邻基站，若所述相邻基站的相邻基站中只有一个所述目标基站，将所述相邻基站相对于所述目标基站的预分配频谱分配给所述相邻基站；若所述相邻基站的相邻基站中有多个所述目标基站，根据所述相邻基站相对于每个所述目标基站的预分配频谱，为所述相邻基站进行频谱分配。
基站20，用于确定频谱分配设备为所述基站分配的频谱；在所述频谱分配设备分配的频谱上进行传输。
其中，本发明实施例中的各相邻基站以及目标基站可以归属于不同的运营商。
频谱分配设备在建站初期可以通过预先配置的方式获取各运营商站点位置信息，或者在运营期间由运营商上报所辖基站的地理位置信息。
频谱分配设备在为相邻基站分配频谱时，可以将频谱分配结果以信令消息发送给运营商各基站。
本发明实施例中的目标基站是已进行频谱分配的基站，针对一个目标基站，确定该目标基站周围的基站中需要进行频谱分配的相邻基站，然后确定每个所述相邻基站相对于所述目标基站的预分配频谱。
对于相邻基站，有可能周围会有多个目标基站，针对每一个基站都会确定该相邻基站相对于目标基站的预分配频谱。
如果只有一个相对于目标基站的预分配频谱，则只需要将相对于目标基站的预分配频谱分配给所述相邻基站；
如果有多个相对于目标基站的预分配频谱，将所述相邻基站相对于每个所述目标基站的预分配频谱的交集频谱分配给所述相邻基站。
比如相邻基站1周围有目标基站A和目标基站B，则频谱分配设备会确定相邻基站1相对于目标基站A的预分配频谱A，以及确定相邻基站1相对于目标基站B的预分配频谱B，然后将预分配频谱A和预分配频谱B的交集频谱分配给所述相邻基站1。
由于频谱分配设备确定相邻基站相对于目标基站的预分配频谱时，针对
每个目标基站确定的预分配频谱的方式都相同，所以不再针对不同的目标基站分别进行介绍，下面只针对某一个目标基站进行介绍。
本发明实施例的频谱分配设备接收运营商基站的频谱需求信息，并确定多运营商的基站间关系；各基站上报自身地理位置，以及频谱带宽需求、自身射频能力等信息。频谱分配设备统计并分析全部基站位置(包括已部署基站和提出频谱需求的基站)，划分各个基站的类型。
具体的，频谱分配设备根据目标基站与每个所述相邻基站之间的距离，确定每个所述相邻基站相对于所述目标基站的可用频谱时，针对一个所述相邻基站，所述频谱分配设备根据距离范围和用于表示与目标基站距离的类型的对应关系，确定目标基站与所述相邻基站之间的距离所属的范围对应的类型，并将确定的类型作为所述相邻基站的类型；
所述频谱分配设备根据每个相邻基站的类型，确定每个所述相邻基站相对于所述目标基站的可用频谱。
本发明实施例频谱分配设备根据划分基站类别所需的预设条件，确定每个相邻基站的类型。
其中，预设条件是距离范围，具体的距离范围可以根据仿真、经验等设定。比如可以设定第一距离和第二距离，这样可以将基站类型划分为三种：
表示与目标基站之间距离远的第一类型(参见图1B)：满足站点间距离大于等于第一距离的两个基站，可以认为通常远大于两个站点覆盖半径之和，这时可以使用相同工作频率，此时基站间的相互干扰的功率密度约等于噪声。
表示与目标基站之间距离较远的第二类型(参见图1C)：满足站点间距离小于第一距离、且大于等于第二距离的两个基站，即通常略大于两个站点覆盖半径之和，可以认为使用邻近频率工作，此时来自一个基站发射信号泄露到另一个基站工作频带内，形成干扰，该干扰的功率密度约等于噪声。
表示与目标基站之间距离近的第三类型(参见图1D)：满足站点间距离小于第二距离的两个基站，即通常小于等于两个站点覆盖半径之和，可以认为使用较远频率工作，使得基站间的泄露干扰功率密度约等于噪声。
对于第一类型基站，认为相邻基站和目标基站间间隔远，互相无重叠，可认为满足同频覆盖条件，所以所有频谱均可用；
对于第二类型基站，认为相邻基站和目标基站间的地理位置相邻，根据相互间地理隔离情况，在满足一定频率隔离时，进行邻频共存，则统计每个第二类型基站与目标基站的地理隔离距离，然后确定每个第二类型基站在最小地理隔离距离(周边多个目标基站与该第二类型基站的距离是不同的，选择最小的距离，则对应最大的频谱隔离)情况下所对应的频率隔离度，那么满足频谱隔离度的频谱即为可用频谱。需要注意的是，因为周边第二类型基站可能包括宏站和小站，虽然宏站与当前站的地理隔离较远，但宏站的发射功率大，因此也可能需要较大的频谱隔离。所以，对周边站要区分宏站和小站来处理。
对于第三类型基站基站，认为相邻基站和目标基站位于部分重叠的区域，则频谱分配设备接收第三类型基站的邻区干扰测量上报，统计在每个频谱上的总干扰情况，然后为第三类型基站选择总干扰较小的频谱作为可用频谱。每个频谱可以等于第三类型基站的射频带宽能力。
基于上述内容，所述频谱分配设备根据每个相邻基站的类型，确定每个所述相邻基站相对于所述目标基站的可用频谱，具体的：
一、若所述相邻基站的类型为表示与目标基站之间距离远的第一类型，针对一个第一类型的相邻基站，所述频谱分配设备将所有可用频谱作为所述相邻基站相对于所述目标基站的可用频谱。
也就是说，针对第一类型的相邻基站可以认为相邻基站和目标基站间间隔远，互相无重叠，可认为满足同频覆盖条件。
二、若所述相邻基站的类型为表示与目标基站之间距离较远的第二类型，针对一个第二类型的相邻基站，所述频谱分配设备确定所述相邻基站与相邻的每个特定目标基站之间的距离，并确定最短距离对应的频率隔离度，将满足确定的频率隔离度的频谱作为所述相邻基站相对于所述目标基站的可用频谱，其中所述特定目标基站是与所述相邻基站相邻的所述目标基站中能够使
所述相邻基站的类型作为第二类型的目标基站。
也就是说，针对第二类型的相邻基站可以认为相邻基站和目标基站间的地理位置相邻，根据相互间地理隔离情况，在满足一定频率隔离时，进行邻频共存。
比如相邻基站1周围有目标基站A、目标基站B和目标基站C，其中根据目标基站B和相邻基站1之间的距离可以确定相邻基站1的类型为第二类型，根据目标基站C和相邻基站1之间的距离可以确定相邻基站1的类型为第二类型，则目标基站B和目标基站C就是相对于相邻基站1的特定目标基站。
在确定最短距离时，从目标基站B和相邻基站1之间的距离以及目标基站C和相邻基站1之间的距离中。选择最短距离。
在确定最短距离对应的频率隔离度时，可以预先根据仿真或经验设定距离范围和频率隔离度的对应关系，然后根据距离范围和频率隔离度的对应关系确定最短距离所属的距离范围对应的频率隔离度。
实施中，由于宏站的发射功率要大于小站，因此对于相同的距离来说，宏站与相邻基站间的干扰会比较大，所以所需的频率隔离度也要大于小站。基于此，在设定距离范围和频率隔离度的对应关系时，可以针对不同目标基站的站型，分别进行设定。
频谱分配设备先判断相邻基站是宏站还是小站，若所述相邻基站是宏基站，所述频谱分配设备根据宏基站的距离范围和频率隔离度的对应关系，确定最短距离所属的距离范围对应的频率隔离度；若所述相邻基站是小站，所述频谱分配设备根据小站的距离范围和频率隔离度的对应关系，确定最短距离所属的距离范围对应的频率隔离度。
三、若所述相邻基站的类型为表示与目标基站之间距离近的第三类型，针对一个第三类型的相邻基站，所述频谱分配设备确定所述相邻基站在每个频谱上的总干扰，并选择干扰最小的频谱作为所述相邻基站相对于所述目标基站的可用频谱。
也就是说，针对第三类型的相邻基站可以认为相邻基站和目标基站位于部分重叠的区域，这里包含了近似同覆盖和邻近覆盖。
在实施中，可以根据需要设定每个频谱的宽度，即将整个频谱分成多个频谱基准单元，分相邻基站分配频谱基准单元。频谱基准单元的大小可以根据相邻基站的射频带宽能力设定。比如所述频谱基准单元可以等于相邻基站的射频带宽能力。
在实施中，频谱分配设备对各运营商的基站进行频谱分配时，可以综合其三类基站的可用频谱。为每个运营商的基站分配频谱的结果中可以包含与其它运营商相同或邻近的频谱。
具体的，为每个运营商中的每个待分配的基站分配频谱时，首要满足基站类别所对应的可用频谱范围，其中各类基站的可用频谱范围是第一类型>第二类型>第三类型。
基于此，在进行分配时，先为全部待分配的第三类型分配频谱资源C；再为第二类型分配频谱资源(B-C)。最后为第一类型基站分配频谱资源(A-B)，具体可以参见图1E。具体的：
所述频谱分配设备根据每个所述相邻基站的可用频谱，确定每个所述相邻基站相对于所述目标基站的预分配频谱，包括：
所述频谱分配设备根据每个第三类型的相邻基站的需求带宽，以及每个第三类型的相邻基站相对于所述目标基站的可用频谱，确定每个第三类型的相邻基站相对于所述目标基站的预分配频谱；
所述频谱分配设备从每个第二类型的相邻基站相对于所述目标基站的可用频谱中，去除第三类型的相邻基站相对于所述目标基站的预分配频谱，根据去除后的每个第二类型的相邻基站相对于所述目标基站的可用频谱，以及每个第二类型的相邻基站的需求带宽，确定每个第二类型的相邻基站相对于所述目标基站的预分配频谱；
所述频谱分配设备从所有可用频谱中，去除第三类型的相邻基站相对于所述目标基站的预分配频谱以及第二类型的相邻基站相对于所述目标基站的
预分配频谱，根据去除后的可用频谱以及每个第一类型的相邻基站的需求带宽，确定每个第一类型的相邻基站相对于所述目标基站的预分配频谱。
以上的具体分配方式根据各基站上报的邻区干扰测量结果，在可用频谱资源上以基站上报的带宽需求为单位，统计各单位长度的频谱上干扰强度，并为每个基站选择具有最小干扰强度的满足带宽需求的可用频谱。
如果无法满足，则频谱分配设备降低基站上报需求的带宽，例如基站射频能力可以支持{B1，B2，B3}，且B1>B2>B3，本次上报需求B1无法满足，频谱分配设备将按照B2为该基站再次选择空闲频谱，当最终所有射频能力所支持的带宽都无法满足时，则拒绝基站的请求。
下面以图1F为例对本发明实施例的方案进行说明。
对于上报需求的运营商基站，划分出了三类基站的集合：第一类型基站、第二类型基站、第三类型基站。设macro cell站点归属运营商1，small cell站点归属运营商2。以marco cell站点为参考，且设macro cell站点与small cell a的间距满足大于等于第一距离，macro cell站点与small cell b的间距满足小于第一距离、且大于等于第二距离，macro cell站点与small cell c的间距满足小于第二距离。
那么此时，可以得到的基站类别划分结果为：在以marco cell站点为参考时，small cell a为第一类型基站，small cell b为第二类型基站，small cell c为第三类型基站。
再设各站点上报的频谱带宽需求为：marco cell站点为Ma Hz，small cell a为Sa Hz，small cell b为Sb Hz，small cell c为Sc Hz。且总可用带宽资源B Hz满足上述各站点带宽需求。
在总可用带宽B中，由第二类型站点small cell c进行邻区干扰测量，在可用资源B Hz内以Sc Hz为单位，统计各单位带宽长度的频谱上干扰强度，选择具有最小干扰强度的带宽Sc Hz，并将这个带宽作为频谱资源C，分配给small cell c。
再由第二类型站点small cell b进行邻区干扰测量，在可用资源B Hz内除
掉Sc Hz之外的频谱上，以(Sb-Sc)Hz为单位，统计各单位带宽长度的频谱上干扰强度，选择具有最小干扰强度的带宽(Sb-Sc)Hz，将这个带宽作为频谱资源(B-C)，连同频谱资源C一同分配给B类站点small cell b。
最后，由于第一类型站点之间可以同频工作，因此在可用带宽内除掉频谱资源(B-C)和频谱资源C之外的剩余部分(B-Sb)Hz上，不需测量，任意为small cell a选择带宽为(Sa-Sb)Hz，作为频谱资源(A-B)，连同频谱资源(B-C)和频谱资源C一同分配给A类站点small cell a。
经过上述分配，实现了频谱资源的最优化利用，即各个small cell站点间最大程度复用频谱资源，同时在同一运营商内可以通过同频组网避免各站点间的干扰。另外，还能满足与另一运营商站点macro cell之间的共存。
