Description

频谱管理装置、电子设备以及由其执行的方法
本申请要求于2017年1月13日提交中国专利局、申请号为201710026388.6、发明名称为“频谱管理装置、电子设备以及由其执行的方法”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。
技术领域
本发明的实施例总体上涉及无线通信领域，具体地涉及利用认知无线电技术的无线通信系统中的频谱资源管理，更具体地涉及一种频谱管理装置、用于次系统的电子设备、由频谱管理装置执行的方法以及由用于次系统的电子设备执行的方法。
背景技术
随着无线通信技术的发展，用户对高品质、高速度、新服务的服务需求越来越高。无线通讯运营商和设备商要不断改进系统以满足用户的需求。这需要大量的频谱资源来支持不断出现的新服务和满足高速通信需求，频谱资源例如可以用时间、频率、带宽、可容许最大发射功率等参数来量化。目前，有限的频谱资源已经分配给固定的运营商和服务，新的可用频谱是非常稀少的或者是价格昂贵的。在这种情况下，提出了动态频谱利用的概念，即动态地利用那些已经分配给某些服务但是却没有被充分利用的频谱资源。
认知无线电(Cognitive Radio,CR)技术作为软件无线电技术的一个智能化演进，能够使非授权用户通过一定的规则动态接入授权频谱，极大地提高了实际的频谱利用率。可以认为，认知无线电系统包括主系统和次系统，其中，已被授权使用频谱的系统被称为主系统，根据一定的规则动态接入该授权频谱的非授权通信系统被称为次系统。可替选地，次系统也可以是具有频谱使用权的系统，但是在频谱使用上具有比主系统低的优先级别。此外，在一个区域中还可以设置称为频谱协调器(Spectrum Coordinator,SC)的功能模块以及称为地理位置数据库(Database，DB)的功能模块来管理次系统并为其分配资源。
这种主次系统共存的通讯方式要求次系统不会对主系统造成不良影响，或者说次系统所造成的影响被控制在主系统容许的范围之内。当有多个次系统的时候，次系统的聚合干扰不能超过主系统的干扰容许范围。因此，有必要提出一种频谱分配的机制，以使得对次系统的频谱分配更加合理，以提高频谱的利用率。
发明内容
这个部分提供了本公开的一般概要，而不是其全部范围或其全部特征的全面披露。
本公开的目的在于提供一种频谱分配的机制，以使得对次系统的频谱分配更加合理，以提高频谱的利用率。
根据本公开的一方面，提供了一种频谱管理装置，包括处理电路，被配置为：针对所述频谱管理装置管理的第一次系统，根据所述第一次系统和其它次系统到主系统的距离确定所述其它次系统与所述第一次系统之间的分配系数，所述分配系数表示所述其它次系统和所述第一次系统对所述主系统产生的聚合干扰的干扰程度；以及根据所述分配系数为所述第一次系统分配频谱资源。
根据本公开的另一方面，提供了一种用于次系统的电子设备，包括处理电路，被配置为：从管理所述次系统的频谱管理装置接收频谱资源信息；以及根据所述频谱资源信息获取频谱资源，其中，所述频谱资源是所述频谱管理装置根据通过其它次系统与所述电子设备所在的次系统到主系统的距离确定的所述其它次系统与所述电子设备所在的次系统之间的分配系数为所述电子设备分配的，所述分配系数表示所述其它次系统与所述电子设备所在的次系统对所述主系统产生的聚合干扰的干扰程度。
根据本公开的另一方面，提供了一种由频谱管理装置执行的方法，包括：针对所述频谱管理装置管理的第一次系统，根据所述第一次系统和其它次系统到主系统的距离确定所述其它次系统与所述第一次系统之间的分配系数，所述分配系数表示所述其它次系统和所述第一次系统对所述主系统产生的聚合干扰的干扰程度；以及根据所述分配系数为所述第一次系统分配频谱资源。
根据本公开的另一方面，提供了一种由用于次系统的电子设备执行的方法，包括：从管理所述次系统的频谱管理装置接收频谱资源信息；以 及根据所述频谱资源信息获取频谱资源，其中，所述频谱资源是所述频谱管理装置根据通过其它次系统与所述电子设备所在的次系统到主系统的距离确定的所述其它次系统与所述电子设备所在的次系统之间的分配系数为所述电子设备分配的，所述分配系数表示所述其它次系统与所述电子设备所在的次系统对所述主系统产生的聚合干扰的干扰程度。
使用根据本公开的频谱管理装置、用于次系统的电子设备、由频谱管理装置执行的方法以及由用于次系统的电子设备执行的方法，使得频谱管理装置可以根据分配系数为次系统分配频谱资源，这里的分配系数与两个次系统到主系统的距离有关，表征了当两个次系统使用相同频段的频谱资源时这两个次系统对主系统产生的聚合干扰的干扰程度。这样一来，可以为对主系统产生强聚合干扰的次系统分配不同的频谱资源，从而使得次系统的频谱分配更加合理，提高频谱的利用率。

在图1所示的系统中，由于次系统S1和S2距离主系统P1的边缘较近，因而可能会对主系统P1造成干扰，这就需要SC1能够对次系统S1和S2的频谱资源进行合理地分配以使得次系统S1和S2对主系统P1的干扰控制在能够忍受的范围内。例如，主系统P1能够忍受的干扰为10dB，如果次系统S1和S2对主系统P1造成的聚合干扰达到了9dB，那么当主 系统P1的边缘出现新的次系统时，新的次系统与次系统S1和S2对主系统P1造成的聚合干扰很可能超出了10dB，导致新的次系统无法使用主系统P1的频谱资源；而如果次系统S1和S2对主系统P1造成的聚合干扰比较小，例如5dB，那么当主系统P1的边缘出现新的次系统时，通过合理地分配可以使得新的次系统与次系统S1和S2对主系统P1造成的聚合干扰小于10dB，因而新的次系统可以使用主系统P1的频谱资源。由此可见，理想的频谱分配方法应当使得次系统对主系统造成的聚合干扰尽可能地低。
此外，在图1所示的系统中，假定次系统S1和S2属于不同的区域，S1由SC1来管理，而S2由除了SC1以外的其它SC来管理。在本公开中，区域是基于地理位置进行划分的。例如，不同的国家、地区、省市等都可以作为划分的依据。一般来说，在一个区域中有一个SC和DB来管理和分配次系统的频谱资源。如果S1和S2使用了相同的频谱资源，例如都使用广播电视系统中的频道1(CH1)的频谱资源，当SC1的覆盖范围内出现了新的次系统也需要使用CH1的频谱资源时，为了使得新的次系统和次系统S1对主系统P1造成的聚合干扰在一定范围内，很可能需要对次系统S1和次系统S2的频谱使用进行调节。在这种情况下，由于次系统S2不是由SC1管理，因而需要SC1与管理S2的SC进行协调，这将增加额外的信令和时间开销。由此可见，理想的频谱分配方法还应当使得不同区域的次系统尽可能使用不同的频谱资源以减少不同区域的SC之间的信令交互。
为了解决上述技术问题中的至少一个，本公开提出了一种频谱管理装置、用于地理位置数据库的电子设备、用于次系统的电子设备以及由这些装置和设备执行的方法。
值得注意的是，作为一个应用实例，本公开的主系统可以包括广播电视系统，次系统可以包括移动通信系统，例如wifi通信系统。其中，广播电视系统可以包括主用户基站(例如电视塔)和多个主用户(例如电视机)。移动通信系统可以包括次用户基站(例如wifi接入点)和次用户(例如便携式计算机)。当然，在次系统中也可以没有基站，仅存在作为终端设备的次用户，某些次用户可以具有基站的功能。在这样的系统中，可以动态地利用数字广播电视频谱上某些没有播放节目的频道的频谱或者相邻频道的频谱，在不干扰电视信号接收的情况下，进行移动通信，例如wifi通信。
本领域的技术人员应该理解，虽然上述列举了主系统为广播电视系统的情形，但是本申请并不限于此，主系统也可以为其他具有合法频谱使用权的通信系统，而次系统也可以为其他需要利用频谱资源进行通信的系统。
<2.第一实施例>
在这个实施例中，将详细描述根据本公开的实施例的频谱管理装置200。这里，频谱管理装置200例如可以是频谱协调器SC。图2是示出根据本公开的实施例的频谱管理装置200的配置的示例的框图。
如图2所示，频谱管理装置200可以包括处理电路210。需要说明的是，频谱管理装置200既可以包括一个处理电路210，也可以包括多个处理电路210。
进一步，处理电路210可以包括各种分立的功能单元以执行各种不同的功能和/或操作。需要说明的是，这些功能单元可以是物理实体或逻辑实体，并且不同称谓的单元可能由同一个物理实体实现。
根据本公开的实施例，处理电路210可以包括确定单元211和分配单元212。
根据本公开的实施例，确定单元211可以针对频谱管理装置200管理的第一次系统，根据第一次系统和其它次系统到主系统的距离确定其它次系统与第一次系统之间的分配系数。分配系数表示其它次系统和第一次系统对主系统产生的聚合干扰的干扰程度。
这里，第一次系统可以是频谱管理装置200覆盖范围内的任意一个次系统，其它次系统是除了第一次系统以外的其它次系统。也就是说，确定单元211可以针对频谱管理装置200管理的任意一个次系统，确定其与其它次系统之间的分配系数。
这里，分配系数是针对两个次系统的参数，与两个次系统到主系统的距离有关，其表示当两个次系统使用相同的频谱资源时这两个次系统对主系统产生的聚合干扰的干扰程度。根据本公开的实施例，确定单元211可以确定其它次系统与第一次系统之间的分配系数，并可以将确定的分配系数发送到分配单元212。
根据本公开的实施例，分配单元212可以根据分配系数为第一次系 统分配频谱资源。这里，分配单元212可以从确定单元211获取第一次系统与其它次系统的分配系数，并根据分配系数来分配频谱资源。
这里，第一次系统可以是频谱管理装置200覆盖范围内的任意一个次系统，其它次系统是除了第一次系统以外的其它次系统。也就是说，分配单元212可以针对频谱管理装置200管理的任意一个次系统，根据这任意一个次系统与其它次系统之间的分配系数为其分配频谱资源。
由此可见，根据本公开的实施例，频谱管理装置200在分配频谱资源时考虑了次系统之间的分配系数，而分配系数表示两个次系统对主系统产生的聚合干扰的干扰程度。也就是说，频谱管理装置200可以对次系统进行频谱资源分配以使得次系统对主系统产生的聚合干扰尽可能小。
根据本公开的实施例，处理电路210中的确定单元211可以根据第一次系统和其它次系统到主系统覆盖范围内的参考点的距离确定第一次系统和其它次系统到主系统的距离。也就是说，可以将主系统覆盖范围内的参考点作为主系统的代表，并用次系统到参考点的距离表征该次系统到参考点所在的主系统的距离。
根据本公开的实施例，主系统覆盖范围内的参考点包括与第一次系统对应的第一参考点以及与其它次系统对应的第二参考点。
图3是示出根据本公开的另一个实施例的频谱管理装置的配置的示例的框图。如图3所示，频谱管理装置200的处理电路210还可以包括收发单元220。频谱管理装置200可以通过收发单元220与其它设备进行通信，包括发送信息和接收信息等。
根据本公开的实施例，收发单元220可以接收第一参考点信息以及第二参考点信息。
在本公开中，参考点是对应于次系统的参数。每一个次系统都可以有对应的参考点。次系统对应的参考点可以是受到该次系统干扰的一个或者多个主系统中受到干扰最严重的点。这里，可以用各种参数来衡量主系统受到的干扰情况。例如，次系统距离主系统的距离，主系统还能够容忍的干扰量等等。也就是说，次系统对应的参考点可以是受到该次系统干扰的一个或者多个主系统中距离该次系统最近的点，也可以是受到该次系统干扰的一个或者多个主系统中还能够容忍的干扰量最小的边缘位置。一般来说，次系统的参考点位于该次系统所在区域内的主系统的覆盖范围内，更具体地，在主系统的边缘位置。然而，当次系统位于多个区域交界处从 而对多个主系统造成干扰时，该次系统的参考点很可能位于与该次系统处于不同区域的其它主系统的覆盖范围内。此外，在一般情况下，不同的次系统所对应的参考点不同，当然也存在不同的次系统对应相同的参考点的情况。根据本公开的实施例，收发单元220可以接收第一次系统和其它次系统的参考点信息，并可以将接收到的参考点信息发送到处理电路210，例如确定单元211。
根据本公开的实施例，处理电路210中的确定单元211还可以基于第一参考点信息和第二参考点信息确定第一次系统和其它次系统到主系统的距离，并进而确定分配系数。具体地，第一次系统和其它次系统到主系统的距离可以包括：第一次系统到第一参考点的距离、第一次系统到第二参考点的距离、其它次系统到第一参考点的距离和其它次系统到第二参考点的距离。
这里，第一参考点和第二参考点可以位于相同的主系统的覆盖范围内，也可以位于不同的主系统的覆盖范围内。下面将针对这两种情况进行详细说明。
根据本公开的实施例，第一参考点和第二参考点可以位于相同的主系统的覆盖范围内。在这种情况下，主系统包括第一参考点和第二参考点所在的主系统，即一个主系统。其它次系统和第一次系统之间的分配系数表示其它次系统与第一次系统对第一参考点和第二参考点所在的主系统产生的聚合干扰的干扰程度。
图4是示出根据本公开的实施例的确定两个次系统之间的分配系数的过程的示意图。如图4所示，次系统S1对应的参考点R1和次系统S2对应的参考点R2均位于主系统P1的覆盖范围内。在这种情况下，次系统S1和S2之间的分配系数表示次系统S1和S2对主系统P1产生的聚合干扰的干扰程度。这里，可以将次系统S1看作第一次系统，次系统S2看作其它次系统，参考点R1作为第一参考点，参考点R2作为第二参考点。下面将详细描述在这种情况下分配系数的确定。
根据本公开的实施例，处理电路210中的确定单元211可以分别基于第一参考点和第二参考点确定第一干扰程度和第二干扰程度，并且可以基于第一干扰程度和第二干扰程度确定分配系数。也就是说，次系统S1和S2之间的分配系数可以根据基于参考点R1确定的干扰程度和基于参考点R2确定的干扰程度来确定。
根据本公开的实施例，处理电路210中的确定单元211可以基于第一次系统和第一参考点之间的距离以及其它次系统和第一参考点之间的距离确定第一干扰程度，并且可以基于第一次系统和第二参考点之间的距离以及其它次系统和第二参考点之间的距离确定第二干扰程度。这里，可以规定次系统中的一个位置，例如次系统的中心或者次系统基站的位置作为次系统的代表来计算该次系统与参考点之间的距离。
在本公开的示例中，为了计算简便，仅考虑了次系统与参考点之间的距离来确定分配系数。本领域技术人员应当理解，其它一些参数，例如发射机的特性诸如天线波束参数、天线高度和传输模型等也会影响分配系数的确定。
如图4所示，次系统S1与参考点R1之间的距离为d11，次系统S1与参考点R2之间的距离为d12，次系统S2与参考点R1之间的距离为d21，次系统S2与参考点R2之间的距离为d22。由此可以确定第一干扰程度G1为：
Figure PCTCN2017115853-appb-000001
其中，α表示传输路径的衰落指数，可以根据经验值或者根据测试来确定。同样地，可以确定第二干扰程度G2为：
Figure PCTCN2017115853-appb-000002
接下来，处理电路210中的确定单元211可以基于第一干扰程度G1和第二干扰程度G2确定次系统S1和S2之间的分配系数C12。例如，确定单元211可以确定分配系数C12为第一干扰程度G1和第二干扰程度G2的加权和。作为一个简单的示例，分配系数C12可以为第一干扰程度G1和第二干扰程度G2的和，即：
Figure PCTCN2017115853-appb-000003
以上详细描述了在第一参考点和第二参考点不同的情况下如何确定两个次系统之间的分配系数。然而，也可能出现第一参考点和第二参考点相同的情况。在这种情况下，处理电路210中的确定单元211可以基于第一次系统和第一参考点(第二参考点)之间的距离以及其它次系统和第一 参考点(第二参考点)之间的距离确定分配系数。也就是说，在上面的示例中，仅仅计算G1和G2中的一者并作为分配系数C12。
根据本公开的实施例，第一参考点和第二参考点也可以位于不同的主系统的覆盖范围内。在这种情况下，主系统包括第一参考点所在的主系统和第二参考点所在的主系统，即两个主系统。其它次系统与第一次系统之间的分配系数表示其它次系统与第一次系统对第一参考点所在的主系统产生的聚合干扰的干扰程度以及对第二参考点所在的主系统产生的聚合干扰的干扰程度。
图5是示出根据本公开的另一个实施例的确定两个次系统之间的分配系数的过程的示意图。如图5所示，次系统S1对应的参考点R1位于主系统P1的覆盖范围内，而次系统S2对应的参考点R2位于主系统P2的覆盖范围内。在这种情况下，次系统S1和S2之间的分配系数表示次系统S1和S2对主系统P1以及主系统P2产生的聚合干扰的干扰程度。这里，可以将次系统S1看作第一次系统，次系统S2看作其它次系统，参考点R1作为第一参考点，参考点R2作为第二参考点。下面将详细描述在这种情况下分配系数的确定。
根据本公开的实施例，处理电路210中的确定单元211可以基于第一次系统和第一参考点之间的距离以及其它次系统和第一参考点之间的距离确定其它次系统与第一次系统对第一参考点所在的主系统产生的聚合干扰的干扰程度，并可以基于第一次系统和第二参考点之间的距离以及其它次系统和第二参考点之间的距离确定其它次系统与第一次系统对第二参考点所在的主系统产生的聚合干扰的干扰程度。也就是说，次系统S1和S2之间的分配系数可以根据基于参考点R1确定的对主系统P1产生的聚合干扰的干扰程度和基于参考点R2确定的对主系统P2产生的聚合干扰的干扰程度来确定。
如图5所示，次系统S1与参考点R1之间的距离为d11，次系统S1与参考点R2之间的距离为d12，次系统S2与参考点R1之间的距离为d21，次系统S2与参考点R2之间的距离为d22。根据本公开的实施例，可以根据上述公式(1)来计算G1，并可以根据上述公式(2)来计算G2。此时，G1表示次系统S1和S2对主系统P1产生的聚合干扰的干扰程度，G2表示次系统S1和S2对主系统P2产生的聚合干扰的干扰程度。接下来，确定单元211可以根据上述公式(3)来计算次系统S1和S2之间的分配系数C12。即，其它次系统和第一次系统之间的分配系数可以为对第一参考 点所在的主系统产生的聚合干扰的干扰程度和对第二参考点所在的主系统产生的聚合干扰的干扰程度的加权和，更简单地，可以为对第一参考点所在的主系统产生的聚合干扰的干扰程度和对第二参考点所在的主系统产生的聚合干扰的干扰程度的和。
由此可见，无论第一参考点和第二参考点是否位于相同的主系统的覆盖范围内，分配系数都可以由两部分组成，一部分是根据第一次系统和其它次系统到第一参考点的距离确定的干扰程度，另一部分是根据第一次系统和其它次系统到第二参考点的距离确定的干扰程度。当第一参考点和第二参考点位于相同的主系统的覆盖范围内时，这两部分都表示其它次系统和第一次系统对第一参考点和第二参考点所在的主系统产生的聚合干扰的干扰程度；当第一参考点和第二参考点位于不同的主系统的覆盖范围时，这两部分分别表示对第一参考点所在的主系统和第二参考点所在的主系统产生的聚合干扰的干扰程度。
如上所述，确定单元211可以确定其它次系统与第一次系统之间的分配系数。这里，分配系数表示其它次系统和第一次系统对参考点所在的主系统产生的聚合干扰的干扰程度。当参考点所在的主系统存在多个时，分配系数表示的就是对这多个主系统产生的聚合干扰的干扰程度。这样一来，在分配频谱时考虑了次系统对主系统的干扰关系，由此可以减小在主系统处产生的聚合干扰。
此外，上述的计算方法仅仅是示例性的，还可以根据其它的方法利用次系统到参考点的距离来计算分配系数。另外，还可以根据其它一些参数，例如发射机的特性诸如天线波束参数、天线高度和传输模型等来确定分配系数。
根据本公开的实施例，次系统对应的参考点可以由该次系统所在的区域内的地理位置数据库来确定。也就是说，每个区域内的地理位置数据库都可以确定其覆盖范围内的次系统对应的参考点。
根据本公开的实施例，收发单元220可以从频谱管理装置200所在区域内的地理位置数据库接收第一参考点信息。这里，由于第一次系统处于频谱管理装置200的覆盖范围内，因而第一参考点可以由这个区域内的地理位置数据库来确定。
根据本公开的实施例，其它次系统可以处于频谱管理装置200的覆盖范围外，也可以处于频谱管理装置200的覆盖范围内。下面将详细说明 其它次系统的确定。
根据本公开的实施例，处理电路210可以根据地理位置信息来确定其它次系统。这里，其它次系统可以包括一个或者多个其它次系统，处理电路210中的确定单元211可以确定一个或者多个其它次系统中的每个次系统与第一次系统之间的分配系数。也就是说，分配单元212可以根据每个次系统与第一次系统之间的分配系数来为第一次系统分配频谱资源。此外，每个次系统都对应有一个参考点，当其它次系统包括多个次系统时，第二参考点也有多个。
根据本公开的实施例，其它次系统包括对频谱管理装置200所在区域内的主系统造成干扰并且由除频谱管理装置200之外的其它频谱管理装置管理的一个或者多个次系统。也就是说，其它次系统与第一次系统位于不同的区域，或者说由不同的频谱管理装置管理。
图6是示出根据本公开的实施例的确定其它次系统的过程的示意图。如图6所示，次系统S1位于区域1中，在区域1中存在主系统P1、频谱管理装置SC1和地理位置数据库DB1，次系统S1由频谱管理装置SC1来管理。次系统S2和S3位于区域2中，在区域2中存在主系统P2、频谱管理装置SC2和地理位置数据库DB2，次系统S2和S3由频谱管理装置SC2来管理。这里，次系统S1可以看做第一次系统，而次系统S2和S3由于距离主系统P1较近，因而对主系统P1造成干扰。在这种情况下，处理电路210可以确定次系统S2和S3作为其它次系统。
值得注意的是，图6仅仅示出了其它次系统包括两个次系统的情形。当然，其它次系统也可以包括一个次系统或者多于两个的次系统。
根据本公开的实施例，次系统S2对应的参考点和次系统S3对应的参考点(即第二参考点)可以由地理位置数据库DB2来确定，而SC2可以访问数据库DB2而获取第二参考点信息。接下来，根据本公开的实施例，收发单元220可以从除频谱管理装置200之外的其它频谱管理装置接收第二参考点信息。也就是说，不同区域的频谱管理装置之间可以进行信息交互，包括各自管理的次系统的位置、频谱资源以及参考点信息等。
也就是说，根据本公开的实施例，当其它次系统与第一次系统位于不同的区域时，收发单元220可以从管理其它次系统的频谱管理装置来接收第二参考点信息，接下来，确定单元211可以基于从DB1接收的第一参考点信息，以及从SC2接收的第二参考点信息，根据如上所述的方式 来确定每一个其它次系统与第一次系统之间的分配系数，从而分配单元212可以根据每一个其它次系统与第一次系统之间的分配系数为第一次系统分配频谱资源。
根据本公开的实施例，其它次系统可以仅仅包括那些与第一次系统处于不同区域的次系统。这样一来，分配单元212在为第一次系统分配频谱资源时也只考虑与第一次系统与这样的其它次系统之间的分配系数，从而可以尽量避免为分配系数大的次系统分配相同的频谱资源。因此，在区域的交界位置，属于不同区域的次系统的频谱资源尽可能不同，由此减少不同区域间的频谱资源管理装置之间的信令交互。
根据本公开的实施例，其它次系统还可以包括由频谱管理装置200管理的一个或者多个次系统。也就是说，其它次系统与第一次系统处于相同的区域，或者说由相同的频谱资源管理装置管理。
图7是示出根据本公开的另一个实施例的确定其它次系统的过程的示意图。如图7所示，次系统S1和S4都位于区域1中，在区域1中存在主系统P1、频谱管理装置SC1和地理位置数据库DB1，次系统S1和S4由频谱管理装置SC1来管理。在这种情况下，处理电路210可以仅确定次系统S4作为其它次系统，也可以确定次系统S2、S3和S4都作为其它次系统。
值得注意的是，图7仅仅示出了与第一次系统位于相同区域的其它次系统包括一个次系统的情形。当然，这样的其它次系统也可以包括多个次系统。
根据本公开的实施例，次系统S4对应的参考点(第二参考点)可以由DB1来确定。因此，收发单元220可以从频谱管理装置200所在区域内的地理位置数据库接收第二参考点信息。
也就是说，根据本公开的实施例，当其它次系统与第一次系统位于不同的区域时，收发单元220可以从管理其它次系统的频谱管理装置来接收第二参考点信息；当其它次系统与第一次系统位于相同的区域时，收发单元220可以从这个区域内的地理位置数据库来接收第二参考点信息。接下来，确定单元211可以基于从DB1接收的第一参考点信息，以及从DB1和/或SC2接收的第二参考点信息来确定每一个其它次系统与第一次系统之间的分配系数，从而分配单元212可以根据每一个其它次系统与第一次系统之间的分配系数为第一次系统分配频谱资源。
如上所述，无论其它次系统是否与第一次系统位于相同的区域，确定单元211都可以确定其它次系统与第一次系统之间的分配系数。然而，根据本公开的另一个实施例，当其它次系统与第一次系统位于不同的区域时，收发单元220可以从其它次系统所在的频谱管理装置来接收其它次系统与第一次系统的分配系数。即，当第一次系统和其它次系统位于不同的区域时，可以由第一次系统所在区域的频谱管理装置来确定其它次系统与第一次系统之间的分配系数，也可以由其它次系统所在区域的频谱管理装置来确定其它次系统与第一次系统之间的分配系数。
根据本公开的实施例，收发单元220还可以向其它次系统所在区域的频谱管理装置发送第一次系统的位置信息，或者发送第一次系统的位置信息和第一参考点信息，以便于其它次系统所在区域的频谱管理装置确定上述分配系数。例如，在图7所示的实施例中，SC1可以向SC2发送次系统S1的位置信息，或者发送次系统S1的位置信息和第一参考点信息，然后从SC2接收次系统S3与S1之间的分配系数，以及次系统S2与S1之间的分配系数。
根据本公开的实施例，确定单元211可以仅确定那些由频谱管理装置200管理的其它次系统与第一次系统之间的分配系数，收发单元220可以接收那些由其它频谱管理装置管理的其它次系统与第一次系统之间的分配次数，从而分配单元212可以根据确定单元211确定的分配系数以及收发单元220接收的分配系数为第一次系统分配频谱资源。
根据本公开的实施例，其它次系统可以仅仅包括那些与第一次系统处于相同区域的次系统。这样一来，分配单元212在为第一次系统分配频谱资源时也只考虑与第一次系统与这样的其它次系统之间的分配系数，从而可以尽量避免为分配系数大的次系统分配相同的频谱资源，由此减少在主系统处受到的聚合干扰。
根据本公开的实施例，其它次系统可以既包括那些与第一次系统处于相同区域的次系统，也包括那些与第一次系统处于不同区域的次系统。这样一来，分配单元212在为第一次系统分配频谱资源时考虑第一次系统与所有其它次系统之间的分配系数，由此可以减少在主系统处受到的聚合干扰，并且减少不同区域间的频谱资源管理装置之间的信令交互。
如上所述，确定单元211可以确定其它次系统与第一次系统之间的分配系数。接下来，将详细描述分配单元212如何根据确定单元211确定的分配系数为第一次系统分配资源。
根据本公开的实施例，处理电路210中的分配单元212可以被配置为：在其它次系统与第一次系统之间的分配系数大于特定阈值时，为第一次系统和其它次系统分配频率上正交的频谱资源。进一步，分配单元212还可以被配置为：在其它次系统与第一次系统之间的分配系数小于特定阈值时，为第一次系统和其它次系统分配频率上相同的频谱资源。
也就是说，分配单元212为次系统分配频谱资源的原则是尽量避免为分配系数大的两个次系统分配相同的频谱资源。这样做的原因是，分配系数大则说明这两个次系统对主系统产生的聚合干扰的干扰程度大，因而为其分配不同的频谱资源可以有效地减小在主系统处产生的聚合干扰。
根据本公开的实施例，分配单元212可以采用各种实施方式来实现上述目的。例如，分配单元212可以建立由第一次系统和所有的其它次系统构成的无向加权图，无向加权图的边的权重基于由边的两个顶点代表的两个次系统之间的分配系数。
图8是示出根据本公开的实施例的无向加权图的示意图。图8所示的无向加权图是基于图6所示的示例确定的，即其它次系统仅仅包括与第一次系统处于不同区域的那些次系统。如图8所示，无向加权图的顶点表示次系统，顶点之间的边表示所述边所连接的两个顶点代表的次系统之间存在分配系数，边的权重基于所述边所连接的两个顶点代表的两个次系统之间的分配系数。在图8中，w12表示次系统S1和S2之间的边的权重，其基于次系统S1和S2之间的分配系数C12。类似地，w13基于次系统S1和S3之间的分配系数C13，w34基于次系统S4和S3之间的分配系数C34，w24基于次系统S2和S4之间的分配系数C24。
根据本公开的实施例，在确定单元211确定了分配系数C12、C13、C34和C24以后，分配单元212可以确定权重w12、w13、w34和w24，并确定如图8所示的无向加权图。接下来，分配单元212可以根据建立的无向加权图来为第一次系统分配频谱资源。这里，由于第一次系统可以是频谱管理装置200管理的任意一个次系统，因此分配单元212也可以根据无向加权图来为频谱管理装置200管理的其它次系统，例如次系统S4来分配频谱资源。
图9是示出根据本公开的另一个实施例的无向加权图的示意图。图9所示的无向加权图是基于图7所示的示例确定的，即其它次系统不仅包括与第一次系统处于不同区域的那些次系统，还包括与第一次系统处于相同区域的那些次系统。同样地，在图9中，无向加权图的顶点表示次系统， 顶点之间的边表示所述边所连接的两个顶点代表的次系统之间存在分配系数，边的权重基于所述边所连接的两个顶点代表的两个次系统之间的分配系数。
根据本公开的实施例，可以有各种方式来根据分配系数确定权重。一般来说，权重与相应的分配系数成正比。也就是说，其它次系统与第一次系统对主系统产生的聚合干扰的干扰程度越大，在无向加权图中连接其它次系统与第一次系统的边的权重越大。在一个特定的实施例中，无向加权图的边的权重等于由边的两个顶点代表的两个次系统之间的分配系数。
根据本公开的实施例，处理电路210中的分配单元可以被配置为：在无向加权图中代表第一次系统与其它次系统的顶点之间的边的权重大于特定阈值时，为第一次系统和其它次系统分配频率上正交的频谱资源；以及在无向加权图中代表第一次系统与其它次系统的顶点之间的边的权重小于特定阈值时，为第一次系统和其它次系统分配频率上相同的频谱资源。
例如，在图7所示的示例中，次系统S1和S4虽然相距较远，但是距离主系统P1都很近，因而次系统S1和S4之间的分配系数C14可能很大，导致在图9的无向加权图中的权重w14很大。假定w14>w12>w13，或者w14>w13>w12，则分配单元212可以为次系统S1和S4分配频率上正交的频谱资源。
根据本公开的实施例，在图9所示的无向加权图中，无向加权图的边的权重还可以基于由所述边的两个顶点代表的两个次系统是否由相同的频谱管理装置管理。
这里，可以定义次系统之间的参数Aij来表示次系统Si和Sj是否由相同的频谱管理装置管理。例如，可以设定：当次系统Si和Sj由不同的频谱管理装置管理时，参数Aij＝A1；当次系统Si和Sj由相同的频谱管理装置管理时，参数Aij＝A2。
进一步，分配单元212可以根据次系统Si和Sj之间的参数Aij和分配系数Cij来确定无向加权图中连接次系统Si和Sj的边上的权重wij。作为一个非限制性的示例，wij＝Aij×Cij。
前文中提到，其它次系统可以包括那些与第一次系统处于不同区域的次系统，从而使得属于不同区域的次系统的频谱资源尽可能不同，由此减少不同区域间的频谱资源管理装置之间的信令交互。进一步，其它次系 统也可以包括那些与第一次系统处于相同区域的次系统，由此可以减少在主系统处受到的聚合干扰。
根据本公开的实施例，可以根据对系统性能的需求来设定A1和A2的值。例如，当对减少在主系统处受到的聚合干扰的需求大于对减少不同区域间的频谱资源管理装置间的信令交互的需求时，可以设定A1<A2；当对减少在主系统处受到的聚合干扰的需求小于对减少不同区域间的频谱资源管理装置间的信令交互的需求时，可以设定A1>A2。在后者的情况下，当A1远远大于A2时，所达到的效果与图8所示的无向加权图是类似的，即虽然计算了与第一次系统处于相同的区域的其它次系统与第一次系统之间的分配系数，但是这样的分配系数在分配频谱资源时并没有起到决定性的作用。
如上所述，分配单元212可以根据其它次系统与第一次系统之间的分配系数为第一次系统分配频谱资源。根据本公开的实施例，收发单元220还可以向第一次系统发送分配的频谱资源，以便于第一次系统利用分配的频谱资源进行通信。
如上所述介绍了频谱管理装置200。根据本公开的实施例，频谱管理装置200在分配频谱资源时考虑了次系统之间的分配系数，而分配系数表示两个次系统对主系统产生的聚合干扰的干扰程度。也就是说，频谱管理装置200可以对次系统进行频谱资源分配以使得次系统对主系统产生的聚合干扰尽可能小，并且使得与其它的频谱管理装置之间的信令交互尽可能少，从而节约信令开销并提高频谱利用率。
<3.第二实施例>
在这个实施例中，将详细描述根据本公开的实施例的电子设备1000。这里，电子设备1000可以包括地理位置数据库DB。图10是示出根据本公开的实施例的电子设备1000的配置的示例的框图。
如图10所示，电子设备1000可以包括处理电路1010。需要说明的是，电子设备1000既可以包括一个处理电路1010，也可以包括多个处理电路1010。
这里虽然没有示出处理电路1010的功能单元，但是处理电路1010可以包括各种分立的功能单元以执行各种不同的功能和/或操作。需要说明的是，这些功能单元可以是物理实体或逻辑实体，并且不同称谓的单元 可能由同一个物理实体实现。
根据本公开的实施例，处理电路1010可以从电子设备1000所在区域内的次系统接收位置信息。这里，电子设备1000可以从其所在区域内的任意一个次系统接收位置信息。位置信息的接收可以是周期性触发的，也可以是事件性触发的。例如，电子设备1000所在区域内的次系统周期性向电子设备1000上报位置信息，或者当次系统接入主系统时(当次系统为wifi系统时，例如开机操作)向电子设备1000上报位置信息。
根据本公开的实施例，处理电路1010可以根据次系统的位置信息确定与次系统对应的参考点信息。这里，每个次系统都有对应的参考点。次系统对应的参考点可以是受到该次系统干扰的一个或者多个主系统中受到干扰最严重的点。例如，处理电路1010可以通过收发单元获取次系统的位置信息，并根据每个次系统的位置信息确定与其对应的参考点。
根据本公开的实施例，处理电路1010还可以将与次系统对应的参考点信息发送到电子设备1000所在区域内的频谱管理装置。这里的频谱管理装置可以是第一实施例中所述的频谱管理装置200。也就是说，频谱管理装置可以利用参考点信息确定该次系统与其它次系统到主系统的距离，并确定该次系统与其它次系统之间的分配系数，分配系数表示其它次系统与该次系统对主系统产生的聚合干扰的干扰程度，并根据分配系数为该次系统分配频谱资源。这部分内容在第一实施例中已经详细叙述过，在此不再赘述。
根据本公开的实施例，次系统对应的参考点可以是受到该次系统干扰的一个或者多个主系统中距离该次系统最近的点。也就是说，当一个次系统对一个主系统造成干扰时，确定这个主系统中距离该次系统最近的位置为该次系统对应的参考点。当一个次系统对多个主系统造成干扰时，确定多个主系统中距离该次系统最近的位置为该次系统对应的参考点。因此，参考点必然在主系统的边缘位置上。
根据本公开的实施例，次系统对应的参考点可以是受到该次系统干扰的一个或者多个主系统中还能够容忍的干扰量最小的边缘位置。也就是说，当一个次系统对一个主系统造成干扰时，确定这个主系统中还能够容忍的干扰量最小的边缘位置作为与该次系统对应的参考点。当一个次系统对多个主系统造成干扰时，确定多个主系统中还能够容忍的干扰量最小的边缘位置作为与该次系统对应的参考点。
这里，一个边缘位置还能够容忍的干扰量指的是该边缘位置能够容忍的总干扰量与已经受到的干扰量的差值。例如，一个主系统的边缘位置能够容忍的总干扰量为10dB，该边缘位置已经受到了6dB的干扰量，那么该边缘位置还能够容忍的干扰量为4dB。也就是说，一个边缘位置还能够容忍的干扰量越小，表示这个边缘位置所受到的干扰越严重。
下面将结合图11来详细说明参考点的确定。图11是示出根据本公开的实施例的确定参考点的过程示意图。
如图11所示，次系统位于主系统P1的覆盖范围的外侧。在图11中，假定次系统只对一个主系统，即主系统P1造成干扰。那么根据本公开的实施例，可以确定主系统P1中距离该次系统最近的位置为该次系统对应的参考点。如图11所示，可以确定点A为次系统对应的参考点。根据本公开的实施例，还可以确定主系统P1中还能够容忍的干扰量最小的边缘位置作为参考点。例如，假定边缘位置A还能够容忍的干扰量为5dB，边缘位置B还能够容忍的干扰量为3dB。那么，虽然次系统距离边缘位置A比较近，那么也可以确定边缘位置B作为该次系统对应的参考点。
如上所述，电子设备1000可以根据次系统的位置信息确定次系统对应的参考点，并可以将参考点信息发送到频谱管理装置200。由此，频谱管理装置200可以计算次系统之间的分配系数，从而减小主系统处的聚合干扰，并减少不同频谱管理装置之间的信令交互。
根据本公开的实施例，电子设备1000可以包括地理位置数据库DB，并且可以与频谱管理装置200进行交互，因而第一实施例中关于频谱管理装置200的所有实施方式都适用于此。
<4.第三实施例>
在这个实施例中，将详细描述根据本公开的实施例的用于次系统的电子设备1200。这里，电子设备1200可以是次系统中的基站设备。当次系统中没有基站设备，次系统中的某些终端设备可以具有基站设备的功能时，电子设备1200也可以是次系统中的终端设备。
图12是示出根据本公开的实施例的电子设备1200的配置的示例的框图。
如图12所示，电子设备1200可以包括处理电路1210。需要说明的是，电子设备1200既可以包括一个处理电路1210，也可以包括多个处理 电路1210。
这里虽然没有示出处理电路1210的功能单元，但是处理电路1210可以包括各种分立的功能单元以执行各种不同的功能和/或操作。需要说明的是，这些功能单元可以是物理实体或逻辑实体，并且不同称谓的单元可能由同一个物理实体实现。
根据本公开的实施例，处理电路1210可以从管理次系统的频谱管理装置接收频谱资源信息。这里的频谱管理装置例如可以是第一实施例中的频谱管理装置200。因此，频谱资源可以是频谱管理装置200根据通过其它次系统与电子设备1200所在的次系统到主系统的距离确定的其它次系统与电子设备1200所在的次系统之间的分配系数为电子设备1200分配的，分配系数表示其它次系统与电子设备1200所在的次系统对主系统产生的聚合干扰的干扰程度。
根据本公开的实施例，处理电路1210可以根据获取的频谱资源信息获取频谱资源。这里的频谱资源信息可以包括可以由该次系统使用的频谱资源，例如该频谱资源所对应的频率信息等。接下来，电子设备1200可以利用获取的频谱资源进行通信。
根据本公开的实施例，处理电路1210还可以向电子设备1200所在区域内的地理位置数据库发送电子设备1200的位置信息。这里，地理位置数据库可以包括在例如第二实施例中的电子设备1000中。接下来，电子设备1200所在区域内的地理位置数据库可以根据电子设备1200的位置信息确定与电子设备1200所在的次系统对应的参考点信息。
这里，位置信息的接收可以是周期性触发的，也可以是事件性触发的。例如，电子设备1200周期性向地理位置数据库上报位置信息，或者当电子设备1200接入主系统时(当次系统为wifi系统时，例如开机操作)向地理位置数据库上报位置信息。
如上所述，根据本公开的实施例，次系统的电子设备1200可以从频谱管理装置接收根据与其它次系统之间的分配系数分配的频谱资源信息。这样一来，当电子设备1200使用这样的信息进行通信时，可以减少在主系统处造成的聚合干扰，并可以减少频谱管理装置之间的信令交互。
根据本公开的实施例，电子设备1200可以向地理位置数据库DB(包括在电子设备1000中)发送位置信息，并且可以从频谱管理装置200接收频谱资源信息，因而第一实施例中关于频谱管理装置200和第二实施例 中关于电子设备1000的所有实施方式都适用于此。
图13是示出根据本公开的实施例的分配频谱资源的过程的信令流程图。在图13中，S1表示次系统，该次系统所在区域内存在地理位置数据库DB1和频谱管理装置SC1，SC2是与SC1不同的其它频谱管理装置。如图13所示，在步骤S1310中，S1向DB1上报位置信息。接下来，在步骤S1320中，DB1根据S1上报的位置信息确定与次系统S1对应的参考点。此外，DB1还可以确定SC1在满足对主系统保护的情况下可用的频谱资源。接下来，在步骤S1330中，DB1向SC1发送次系统S1的参考点信息。可选地，DB1还可以发送可用频谱资源，SC1可以从这些可用频谱资源中选择次系统的使用频谱资源。这里如果将次系统S1作为第一次系统，其它次系统包括与次系统S1处于相同区域的次系统，那么DB1还向SC1发送其它次系统的参考点信息。此外，如果其它次系统还包括与次系统S1处于不同区域的次系统，那么，在步骤S1340中，SC2向SC1发送其它次系统的参考点信息，次系统的位置信息以及频谱使用情况。接下来，在步骤S1350中，SC1根据从DB1和SC2发送的参考点信息确定其它次系统与次系统S1之间的分配系数。接下来，在步骤S1360中，SC1为次系统S1分配频谱资源。接下来，在步骤S1370中，SC1向次系统S1发送分配的频谱资源信息。由此，SC1可以使用分配的频谱资源进行通信。
图14是示出根据本公开的另一个实施例的分配频谱资源的过程的信令流程图。同样地，在图14中，S1表示次系统，该次系统所在区域内存在地理位置数据库DB1和频谱管理装置SC1，SC2是与SC1不同的其它频谱管理装置。在步骤S1410中，S1向DB1上报位置信息。接下来，在步骤S1420中，DB1根据S1上报的位置信息确定与次系统S1对应的参考点。此外，DB1还可以确定SC1在满足对主系统保护的情况下可用的频谱资源。在步骤S1430中，DB1向SC1发送次系统S1的参考点信息以及可用频谱资源。SC1可以从这些可用频谱资源中选择次系统的使用频谱资源。这里如果将次系统S1作为第一次系统，其它次系统包括与次系统S1处于相同区域的次系统，那么DB1还向SC1发送其它次系统的参考点信息。此外，在步骤S1440中，如果其它次系统还包括与次系统S1处于不同区域的次系统，那么，SC1可以将第一次系统的地理位置信息或者次系统的地理位置信息以及参考点信息发送至SC2。在步骤S1450中，SC1确定与次系统S1位于相同频谱管理装置覆盖范围内的其它次系统与次系统S1之间的分配系数。在步骤S1460中，SC2可以根据其所管理的次系统以及所拥有的主系统信息确定第一次系统S1与各个SC2所管理的 其它次系统之间的分配系数。在步骤S1470中，SC2向SC1发送第一次系统与其它次系统之间的分配系数以及所对应的次系统的频谱使用情况(包括频道和功率等)。接下来，在步骤S1480中，SC1根据在步骤S1450中确定的分配系数和在步骤S1470中接收到的分配次数为次系统S1分配频谱资源。例如，第一次系统可选用的频段为频段1至10，并且已知其它次系统现有频道使用信息以及分配系数，那么SC1可以从信道1至10根据分配系数以及其它次系统频道占用情况为第一次系统选择合适的使用频段。接下来，在步骤S1490中，SC1向次系统S1发送分配的频谱资源信息。由此，SC1可以使用分配的频谱资源进行通信。
