Description

无线通信方法和无线通信设备 技术领域
本发明涉及无线通信方法和无线通信设备，具体地，涉及为次系统分配通信资源的方法和设备。
背景技术
随着无线通信技术的发展，用户对高品质、高速度的服务的需求越来越高，由此产生了对大量通信资源(例如时间、频率)的需求。为了充分利用通信资源，提出了动态频谱利用技术，即，动态地利用已经分配给某些服务但是没有被该服务充分利用的频谱资源。例如，动态地利用数字电视广播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，在不干扰电视信号传输的情况下执行移动通信。在此示例中，数字电视广播系统可被称为主系统，电视机可被视为主用户，而动态地利用未使用频谱资源的移动通信系统被称为次系统，移动通信终端可被视为次用户。
也就是说，主系统通常是指有频谱使用权的系统，例如上述电视广播系统，次系统通常是指没有频谱使用权，但可以在主系统不使用对其分配的频谱资源时适当地使用该资源的系统。此外，主、次系统也可以都具有频谱使用权，但是在频谱使用方面具有不同的优先级别。例如，运营商在部署新的基站以提供新的服务时，已有的基站以及其所提供的服务具有频谱使用优先权。主系统由主用户和服务于主用户的基站组成。次系统由次用户和服务于次用户的基站组成，具体来说，用于次用户的基站与一个或多个次用户之间的通信，或者多个次用户之间的通信可以构成一个次系统。
这种主、次系统共存的通信方式要求次系统的通信对主系统的通信不造成不良影响，或者说由于次系统利用该资源而造成的对主系统的干扰被控制在主系统所允许的范围之内。当存在多个次系统时，要求多个次系统的聚合干扰不能超出主系统的允许范围。
发明内容
本发明提出了为次系统分配通信资源(例如频谱资源)的设备和方法。根据本发明的一个方面，提供了一种资源管理设备，包括一个或多个处理器，所述处理器被配置为：从其他资源管理设备获取干扰信息，所述干扰信息包括由所述资源管理设备管理的多个受管理系统之间的相互干扰，以及不受所述资源管理设备管理的一个或多个非被管理系统对所述多个受管理系统的干扰；基于所获取的干扰信息，为每个所述受管理系统确定通信资源；以及将所确定的通信资源通知给相应的受管理系统。
根据本发明的另一个方面，提供了一种资源管理设备，包括一个或多个处理器，所述处理器被配置为：基于由多个系统报告的指示每个系统是否受到其他资源管理设备管理的信息，在所述多个系统中识别受管理系统和非被管理系统；以及基于由每个系统报告的位置信息，确定所述受管理系统之间的相互干扰以及所述非被管理系统对所述受管理系统的干扰，以生成干扰信息。
根据本发明的另一个方面，提供了一种由资源管理设备执行的分配资源的方法，包括：从其他资源管理设备获取干扰信息，所述干扰信息包括由所述资源管理设备管理的多个受管理系统之间的相互干扰，以及不受所述资源管理设备管理的一个或多个非被管理系统对所述多个受管理系统的干扰；基于所获取的干扰信息，为每个所述受管理系统确定通信资源；以及将所确定的通信资源通知给相应的受管理系统。
根据本发明的另一个方面，提供了一种由资源管理设备执行的方法，包括：基于由多个系统报告的指示每个系统是否受到其他资源管理设备管理的信息，在所述多个系统中识别受管理系统和非被管理系统；以及基于由每个系统报告的位置信息，确定所述受管理系统之间的相互干扰以及所述非被管理系统对所述受管理系统的干扰，以生成干扰信息。
根据本发明的另一个方面，提供了一种包括可执行指令的计算机可读介质，所述指令在被信息处理机器执行时使得所述信息处理机器执行上述的方法。
附图说明
可以通过参考下文中结合附图所给出的描述来更好地理解本发明， 其中在所有附图中使用了相同或相似的附图标记来表示相同或者相似的部件。附图连同下面的详细说明一起包含在本说明书中并且形成本说明书的一部分，而且用来进一步说明本发明的优选实施例和解释本发明的原理和优点。在附图中：
图1示意地示出了本发明所适用的通信场景。
图2是根据本发明的一个实施例的分配通信资源的信令图。
图3示出了干扰信息的图形表示。
图4是根据本发明的另一个实施例的分配通信资源的信令图。
图5A示意地示出了同信道组，图5B是图5A的简化图。
图6示出了实现本发明方案的计算机硬件的示例性配置框图。
具体实施方式
图1示意地示出了能够应用本发明的技术方案的通信场景，在该通信场景中可以存在一个或多个第一级频谱管理装置A，每个第一级频谱管理装置A管理一定地理区域内的多个次系统。图1仅示意地示出了一个第一级频谱管理装置A，椭圆形虚线圈表示由该第一级频谱管理装置A管理的地理区域。需要说明的是，本发明所适用的通信场景可以包括多于一个的第一级频谱管理装置A。
在第一级频谱管理装置A的管理区域内存在多个次系统，该多个次系统中的一些可以进一步受到第二级频谱管理装置B管理。图1中示意地示出了受第二级频谱管理装置B管理的次系统220以及不受第二级频谱管理装置B管理的次系统210。
此外，图1中还示意地示出了主系统的覆盖区域以及位于该覆盖区域的边缘处的参考点R。例如，可以将主系统覆盖区域距离多个次系统分布区域最近的位置设置为参考点R，由此参考点R可以代表主系统受到次系统的干扰最强的位置。因此，在控制次系统对主系统造成的聚合干扰时，通常是考虑次系统在参考点R处造成的干扰。
第一级频谱管理装置A用于为其管理区域内的每个次系统分配可用的通信资源(例如可用频谱资源)。第一级频谱管理装置A例如可以是依据国家法规授权的地理位置数据库运营商所提供的频谱分配装置。
第二级频谱管理装置B针对其所管理的每个次系统220，在为该次系统220分配的可用通信资源的范围内进一步确定该次系统220将使用的通信资源。第二级频谱管理装置B例如可以是由网络运营商或者网络提供商提供的频谱分配装置，或者是由某一区域(如办公区域、住宅区域、大学校园等)的网络管理机构提供的频谱分配装置。
第二级频谱管理装置B不对其所管理的次系统220访问哪一个第一级频谱管理装置做出限定，而只是在对该次系统220分配的可用通信资源的范围内进一步确定将由该次系统220使用的通信资源。
不受第二级频谱管理装置B管理的次系统210可以在第一级频谱管理装置A对其分配的可用通信资源中自行选择用于通信的资源。此时，如果第二级频谱管理装置B为其所管理的次系统220分配了与邻近的不受管理的次系统210相同的通信资源，则这两个次系统之间将产生相互干扰。因此，第二级频谱管理装置B在为其管理的次系统220分配通信资源时需要尽量避免可能产生干扰的不受管理的次系统210所使用的通信资源。在下文中，将以频谱资源作为通信资源的一个示例来描述本发明的技术方案，但本领域技术人员易于将以下描述的方案应用于其他形式的通信资源。
根据本发明的技术方案，第二级频谱管理装置B在为其所管理的次系统220分配通信资源时不仅考虑各个受管理次系统220之间发生相互干扰的可能性，而且考虑不受管理的次系统210对于受管理次系统220产生干扰的可能性。
以下结合图2来描述根据本发明的一个实施例的为次系统分配通信资源的信令流程。
如图2所示，在步骤210，当需要进行通信时，次系统向第一级频谱管理装置A发送用于请求分配可用通信资源(可用频谱资源)的请求消息，特别地，发送请求消息的次系统可以包括不受第二级频谱管理装置B管理的次系统210以及受到第二级频谱管理装置B管理的次系统220。
次系统发送的请求消息可以包括例如该次系统的标识(ID)、位置信息、射频信息(例如发射模板)、以及指示该次系统是否受到第二级频谱管理装置B管理的信息。对于受管理的次系统220而言，所发送的请求消息还可以进一步包括第二级频谱管理装置B的标识(ID)。
响应于次系统的请求消息，第一级频谱管理装置A在步骤S220基于每个系统的位置信息和射频信息来计算发送请求消息的各个次系统到主系统(例如，参考点R)的聚合干扰，并且基于聚合干扰为每个次系统确定可用的频谱资源。本领域技术人员可以采用任何已知的适当方式来执行这一处理，本文对此不再赘述。
另一方面，在步骤S220中，第一级频谱管理装置A还利用接收到的请求消息中所包含的信息来生成指示各个次系统210，220之间的相互干扰的干扰信息。具体地，该干扰信息可以指示受第二级频谱管理装置B管理的多个次系统220之间的相互干扰，以及每个受管理次系统220受到的来自(一个或多个)不受管理次系统210的干扰，以及每个不受管理次系统210受到的来自(一个或多个)受管理次系统220的干扰。特别地，由于不受管理的次系统210自行地确定要使用的频谱资源，无需第二级频谱管理装置B为其优化频谱分配，因此在本发明的方案中通常不考虑不受管理次系统210受到的来自受管理次系统220的干扰。
由于请求消息中包括指示次系统是否受到第二级频谱管理装置B管理的信息，因此第一级频谱管理装置A可以基于该信息来识别哪些是受管理的次系统220，哪些是不受管理的次系统210。此外，由于请求消息中包括每个次系统的位置信息，因此第一级频谱管理装置A可以基于各个次系统的位置信息来确定它们之间的干扰状况。例如，第一级频谱管理装置A可以确定彼此之间的距离小于预定阈值的两个受管理次系统220之间发生相互干扰。此外，例如，第一级频谱管理装置A可以将距离某一受管理次系统220预定距离以内的一个或多个不受管理次系统210确定为对该受管理次系统220产生干扰。更进一步地，第一级频谱管理装置A可以基于某一受管理次系统220与对其产生干扰的每个不受管理次系统210之间的距离和/或该不受管理次系统210的天线增益，来确定该不受管理次系统对该受管理次系统的干扰强度，并将确定的干扰强度也包含在所生成的干扰信息中。
图3示例性地示出了由第一级频谱管理装置A生成的干扰信息的图形表示。在图3中，白色圆点表示受第二级频谱管理装置B管理的次系统220，黑色圆点表示不受第二级频谱管理装置B管理的次系统210，圆点之间的带箭头的连线代表次系统之间的干扰，并且指示出干扰源以及被干扰对象。在连线上标出的符号“X”、“Y”代表干扰强度，例如，可以使用干扰源与被干扰对象之间的传输路径损耗和干扰源的天线增益的乘 积来表示干扰强度。
需要说明的是，虽然图3中以带箭头的连线示出了干扰方向，但本发明也可以使用不表示干扰方向的无方向图。此外，如上所述，由于不受管理的次系统210自行确定要使用的频谱资源，因此本发明的方案通常不考虑受管理次系统220对于不受管理次系统210产生的干扰，因此在图3所示的干扰关系中没有示出受管理次系统220对于不受管理次系统210的干扰。
此外，在图3中还示出了由两个受管理次系统220组成的干扰协调组(Interference Coordination Group，ICG)，如虚线圈所示。干扰协调组内的次系统220可以自主协调解决相互之间的干扰，因此第二级频谱管理装置B在为它们分配频谱资源时可以忽略它们之间的相互干扰，也就是说，认为它们可以自行协调解决相互之间的干扰问题。例如，这可以通过某一运营商自己实施的管理机制来实现，或者通过不同运营商使用LTE中的网络协助干扰消除技术(NAICT)来实现。因此在图3中，属于该ICG的两个次系统220之间没有表示干扰的连线。
返回参考图2，在步骤S220之后，第一级频谱管理装置A在步骤S230将为每个次系统确定的可用频谱资源分别通知给每个次系统，并且在步骤S240将所生成的干扰信息以及每个次系统(包括次系统210和次系统220)的可用通信资源发送给第二级频谱管理装置B。需要说明的是，步骤S230和S240的执行顺序不限于图2中所示，也可以以相反的顺序或同时地执行步骤S230和S240。
然后，在步骤S250，不受第二级频谱管理装置B管理的次系统210在接收到的可用频谱资源的范围内自行选择某一频谱资源以进行通信。
另一方面，在步骤S260，受到第二级频谱管理装置B管理的次系统220向第二级频谱管理装置B请求分配频谱资源。
响应于次系统220的请求，第二级频谱管理装置B基于接收到的干扰信息，在每个次系统220的可用频谱资源的范围内为该次系统220确定要使用的频谱资源，如步骤S270所示。
现在详细描述步骤S270的处理。针对特定的次系统220，第二级频谱管理装置B根据在步骤S240接收到的干扰信息可以确定对该特定次系统220产生干扰的一个或多个不受管理次系统210，在此假设存在一个对其产生干扰的不受管理次系统2101。此外，第二级频谱管理装置B 根据在步骤S240接收到的可用频谱资源可以得知该特定次系统220以及对其产生干扰的次系统2101分别可以使用的频谱资源的范围。假设特定次系统220的可用频谱资源包含频谱1、频谱2和频谱3，次系统2101的可用频谱资源包含频谱1，频谱3和频谱4，如以下表1所示。此外，对于次系统2101，认为其使用可用频谱资源中的各个频谱1、3、4的概率是相同的，例如均为1/3。
[表1]
特定次系统220 频谱1 频谱2 频谱3  
次系统2101 频谱1   频谱3 频谱4
在此情况下，首先针对特定次系统220的可用频谱资源中的频谱1，计算次系统2101使用频谱1的概率，可以得到概率1/3。然后针对频谱2，计算次系统2101使用频谱2的概率，由于次系统2101的可用频谱资源中不包含频谱2，因此次系统2101使用频谱2的概率为0。类似地，针对频谱3，计算次系统2101使用频谱3的概率，可以得到概率1/3。
可以看出，在特定次系统220的可用频谱资源中，频谱2被不受管理的次系统2101使用的概率最小(0)，这意味着如果特定次系统220使用频谱2进行通信，则其与次系统2101使用相同频谱的可能性最小，从而受到次系统2101干扰的可能性最小(可能性为0)。因此，第二级频谱管理装置B可以为特定次系统220分配频谱2以用于通信。
作为上述示例的变型，假设次系统2101的可用频谱资源仅包含频谱3和频谱4，如以下表2所示。
[表2]
特定次系统220 频谱1 频谱2 频谱3  
次系统2101     频谱3 频谱4
以相同的方式，分别针对特定次系统220的可用频谱1、频谱2和频谱3，计算每个频谱被次系统2101使用的概率。可以看出，频谱1和频谱2被使用的概率小于频谱3被使用的概率，并且频谱1和频谱2被使用的概率彼此相同(都为0)。在此情况下，第二级频谱管理装置B可以选择频谱1和频谱2中的任一个以分配给特定次系统220。
此外，本领域技术人员易于理解的是，如果特定次系统220的可用频谱资源中包含以下频谱：该频谱不包含在次系统2101的可用频谱资源中，则第二级频谱管理装置B可以将该频谱分配给特定次系统220。
在上述示例中假设仅存在一个对特定次系统220产生干扰的不受管理次系统，以下将讨论存在多个产生干扰的不受管理次系统的情况。
在一个示例中，假设特定次系统220的可用频谱资源包含频谱1、频谱2和频谱3，并且存在三个对特定次系统220产生干扰的次系统，分别表示为2101、2102、2103。次系统2101的可用频谱资源包含频谱1，频谱3和频谱4，次系统2102的可用频谱资源包含频谱2和频谱3，次系统2103的可用频谱资源包含频谱2、频谱3和频谱4，如以下表3所示。此外，对于次系统2101、2102、2103中的每一个，认为其使用相应的可用频谱资源中所包含的各个频谱的概率是相同的。以次系统2101为例，认为其使用相应的可用频谱资源中包含的频谱1、频谱3或频谱4的概率是相同的，均为1/3。
[表3]
特定次系统220 频谱1 频谱2 频谱3  
次系统2101 频谱1   频谱3 频谱4
次系统2102   频谱2 频谱3  
次系统2103   频谱2 频谱3 频谱4
在此情况下，首先针对特定次系统220的可用频谱资源中的频谱1，分别计算次系统2101、2102、2103使用频谱1的概率，可以得到三个概率1/3,0,0。然后针对特定次系统220的可用频谱资源中的频谱2，分别计算次系统2101、2102、2103使用频谱2的概率，可以得到概率0，1/2,1/3。类似地，针对特定次系统220的可用频谱资源中的频谱3，分别计算次系统2101、2102、2103使用频谱3的概率，可以得到概率1/3,1/2,1/3。
从表3可以看出，在特定次系统220的可用频谱资源中，频谱1被次系统2101、2102、2103使用的概率最小，这意味着如果特定次系统220使用频谱1进行通信，则其与次系统2101、2102、2103使用相同频谱的可能性最小，从而受到次系统2101、2102、2103干扰的可能性最小。因此，第二级频谱管理装置B可以为特定次系统220分配频谱1以用于 通信。
需要说明的是，以上从表3中可以直观地看出频谱1被使用的概率最小。然而在更一般的情况下，可以根据次系统2101、2102、2103分别使用频谱1的概率1/3,0,0，来计算频谱1被使用的总概率。该总概率是概率1/3,0,0的函数，例如，其是将概率1/3,0,0进行相加或加权相加或其他运算而获得的值。以相同的方式，可以分别计算频谱2和频谱3被使用的总概率。然后，将与最小的总概率对应的频谱分配给特定次系统220。
此外，本领域技术人员易于理解的是，如果特定次系统220的可用频谱资源中还包含频带5，并且频带5不被包含在次系统2101、2102、2103中的任何一个的可用频谱资源中，则特定次系统220使用频带5进行通信将不会受到次系统2101、2102、2103的干扰。因此，第二级频谱管理装置B为特定次系统220分配频谱5以用于通信。
作为上述示例的变型，假设特定次系统220的可用频谱资源包含频谱1、频谱2和频谱3，次系统2101的可用频谱资源包含频谱1、频谱3和频谱4，次系统2102的可用频谱资源包含频谱2、频谱3和频谱5，次系统2103的可用频谱资源包含频谱1、频谱2、频谱3和频谱4，如以下表4所示。

以上述方式，分别针对特定次系统220的可用频谱1、频谱2和频谱3，计算每个频谱被次系统2101、2102、2103使用的概率。可以得到，频谱1被次系统2101、2102、2103使用的概率分别为1/3,0,1/4，频谱2被使用的概率分别为0,1/3,1/4，频谱3被使用的概率分别为1/3,1/3,1/4。从表4可以看出，频谱3被使用的概率最大，频谱1和频谱2被使用的概率较小并且彼此相同。在此情况下，第二级频谱管理装置B可以选择 频谱1和频谱2中的任一个以分配给特定次系统220。
需要说明的是，以上从表4中可以直观地得出频谱3被使用的概率最大，而频谱1和频谱2的概率较小并且彼此相同。然而在更一般的情况下，针对每一个频谱，可以根据次系统2101、2102、2103分别使用该频谱的概率来计算该频谱被使用的总概率，如以上结合表3所描述的。然后，基于各个频谱被使用的总概率来选择要分配给特定次系统220的频谱。
替选地，针对表4所示的情况，如果第二级频谱管理装置B接收到的干扰信息中还包含各个次系统2101、2102、2103对特定次系统220的干扰强度，则第二级频谱管理装置B可以基于该干扰强度来选择频谱1和频谱2中的一个以分配给特定次系统220，而不是任意地选择频谱1和频谱2之一。假设次系统2101、2102、2103对特定次系统220的干扰强度分别表示为A，B，C，并且A>B>C。在此情况下，频谱1可能被次系统2101(具有最大干扰强度A)和次系统2103(具有最小干扰强度C)使用，而频谱2可能被次系统2102(具有中等干扰强度B)和次系统2103(具有最小干扰强度C)使用。因此，第二级频谱管理装置B将为特定次系统220分配频谱2，这是因为虽然特定次系统220使用频谱1和频谱2进行通信而受到干扰的可能性(概率)相同，但是使用频谱2时所受到的干扰强度将更小。
第二级频谱管理装置B在为其所管理的次系统当中的、受到不受管理次系统干扰的次系统分配了频谱资源之后，可以针对其余的没有受到任何不受管理次系统的干扰的受管理次系统分配频谱资源。例如，第二级频谱管理装置B可以根据所接收的干扰信息所指示的这些受管理次系统之间的干扰关系，采用染色法为它们确定频谱资源。
以上述方式，第二级频谱管理装置B为其所管理的各个次系统220确定了频谱资源，然后可以在步骤S280将所确定的频谱资源通知给相应的次系统220。
以下将结合图4来描述根据本发明的另一个实施例的为次系统分配通信资源的信令流程。
如图4所示，在步骤410，当需要进行通信时，次系统向第一级频谱管理装置A发送用于请求分配可用频谱资源的请求消息，该次系统包括不受第二级频谱管理装置B管理的次系统210以及受到第二级频谱管 理装置B管理的次系统220。例如，请求消息可以包括该次系统的标识(ID)、位置信息、射频信息、以及指示该次系统是否受到第二级频谱管理装置B管理的信息。因此，第一级频谱管理装置A可以根据接收到的请求消息来识别受管理次系统220和不受管理次系统210。对于受管理的次系统220而言，其所发送的请求消息还可以进一步包括对其进行管理的第二级频谱管理装置B的标识(ID)。
在步骤S420，第一级频谱管理装置A根据接收到的请求消息，计算发送请求消息的各个次系统到主系统(例如，参考点R)的聚合干扰，并且根据聚合干扰为每个次系统确定可用频谱资源。此外，第一级频谱管理装置A还利用接收到的请求消息中所包含的信息来生成指示各个次系统210，220之间的相互干扰的干扰信息。步骤S410，S420的处理与图2中的步骤S210，S220相同，在此省略其详细描述。
然后，第一级频谱管理装置A在步骤S430将为不受管理次系统210确定的可用频谱资源通知给次系统210，然后次系统210在接收到的可用频谱资源中自行选择用于进行通信的频谱资源，如步骤S440所示。
另一方面，第一级频谱管理装置A在步骤S450将为各个次系统(包括次系统210和次系统220)确定的可用频谱资源以及所生成的干扰信息发送给次系统220。需要说明的是，步骤S450的执行时间不限于图中所示，例如，步骤S450可以与步骤S430同时地执行，或在步骤S430之前执行。
在步骤S460，次系统220向第二级频谱管理装置B请求分配频谱资源，并且同时向第二级频谱管理装置B发送其从第一级频谱管理装置A获得的干扰信息以及每个次系统的可用频谱资源。
响应于次系统220的请求，第二级频谱管理装置B在步骤S470利用接收到的干扰信息，在每个次系统220的可用频谱资源的范围内为该次系统220确定要使用的频谱资源，并且在步骤S480将所确定的频谱资源通知给相应的次系统220。步骤S470和S480的处理与图2中的步骤S270和S280相同，因此在此省略其详细描述。
图4所示的流程可以适用于第一级频谱管理装置A和第二级频谱管理装置B之间不能直接进行通信的情形。
返回参照图3，如上文所述，干扰协调组(ICG)内的多个次系统220可以自主协调解决相互之间的干扰，因此第二级频谱管理装置B可 以为它们分配相同的频谱资源。当ICG内的各个次系统220使用相同的频谱资源时，它们属于同一个同信道组(Common Channel Group，CCG)。
图5A示意地示出了同信道组。如图5A所示，存在四个受第二级频谱管理装置B管理的次系统220A，220B，220C，220D，其中第二级频谱管理装置B根据请求或者根据次系统的特性，将次系统220A和220B分为一个CCG。属于同一CCG的次系统220A和220B由于使用相同频谱而可以被视为一个整体。因此，图5A可以被简化为图5B。在图5B中，次系统220A和220B被合并表示为一个点。
在传统技术中，在划分CCG以及为CCG分配频谱时通常不考虑附近的不受管理次系统(如210A，210B)对于受管理次系统(如220A，220B)的干扰。例如，如图5A所示，次系统220A受到来自不受管理次系统210A(具有可用频谱1和2)的干扰，次系统220B受到来自不受管理次系统210B(具有可用频谱2和3)的干扰，而传统技术不考虑这些干扰，因此有可能为次系统220A和220B所构成的CCG分配频谱1，频谱2或频谱3中的任一个频谱。在这种情况下，该CCG中将至少有一个次系统(次系统220A，或次系统220B，或二者)受到来自次系统210A或210B的干扰。
根据本发明，第二级频谱管理装置B在划分CCG以及为CCG分配频谱时考虑来自不受管理的次系统210A和210B的干扰。例如，在图5A所示的情况下，根据本发明的第二级频谱管理装置B不将次系统220A和220B分为同一个CCG，而是可以将它们分配在不同的CCG中。例如，可以将次系统220A与其他需要避免分配频谱1和频谱2的次系统分为一个CCG，并在排除了频谱1和频谱2的频谱资源中为该CCG分配频谱资源。类似地，可以将次系统220B与其他需要避免使用频谱2和频谱3的次系统分在一个CCG中，并在排除了频谱2和频谱3的频谱资源中为该CCG分配频谱资源。替选地，根据本发明的第二级频谱管理装置B也可以不将次系统220A和220B分配至任何CCG。
此外，如果存在预先划分的一个或多个CCG，而第二级频谱管理装置B在考虑来自不受管理次系统的干扰之后确定该预先划分的CCG不合适，则第二级频谱管理装置B可以重新划分CCG，并且将更新的CCG分组信息通知给相应的受管理次系统。
