图1示出了共享频谱分配系统的构成的一个示意性示例。在该示例中，包括多个频谱管理装置(spectrum manager，SM)，每个SM管理多个服务设备(Service Device，SD)。其中，每个SD可以是由多个无线通信设备构成的网络，该网络至少包括上行和下行两个传输方向。例如，SD可以是一个蜂窝网络的小区，或者是一个WIFI接入点以及WIFI设备构成的网络。SD可以直接和SM进行数据交互，也可以通过中间信息转发节点比如图1中所示的域代理(Domain Proxy，DP)和SM进行数据交互。
此外，如图1中所示，SM可以有多级结构，其中，SM的上标代表该SM所属的级别，SM的下标代表SM的编号，例如SM 1 2表示第一级第二个SM，SM 2 1表示第二级第一个SM，第一级SM位于第二级SM的上层。第二级SM负责管理其所在第一级SM管理的多个SD中的一部分。
一方面，当多个第一级SM管理的多个SD分布在同一地理区域中时，如果可用频谱没有正交化，则在该地理区域内的多个SD间由于缺乏共存协调可能产生资源使用冲突。该冲突例如表现为同频或者邻频干扰。另一方面，当任意第一级SM(例如SM 1 1)管理的多个SD(构成第 一集合Set 1 1)进一步由多个第二级SM(例如SM 2 1和SM 2 2)管理时，每个第二级SM管理的SD是第一集合Set 1 1的一部分，例如分别为第二集合Set 2 1和Set 2 2。SM 1 1根据第一集合Set 1 1以及集合中各SD之间的干扰信息进行频谱分配，分配结果以第二集合Set 2 1和Set 2 2为单位发送给对应的第二级频谱管理装置SM 2 1和SM 2 2。如果第二集合Set 2 1和Set 2 2包含的SD分布在同一地理区域中，并且可用频谱没有正交化，则在由第二级频谱管理装置SM 2 1和SM 2 2分别根据其管理的SD及本地干扰信息等进行频谱分配的情况下，同样会由于缺乏共存协调而可能产生资源使用冲突。
根据本实施例，提供了一种解决或减轻上述资源使用冲突的方案。图2示出了根据本实施例的用于无线通信的电子设备100的功能模块框图，如图2所示，该电子设备100包括：分配单元101，被配置为针对第一级频谱管理装置(SM)所管理的第一集合的频谱分配对象，分配频谱资源；以及生成单元102，被配置为针对位于第一级频谱管理装置下层的第二级频谱管理装置所管理的第二集合的频谱分配对象，生成频谱协调信息以提供给第二级频谱管理装置，该频谱协调信息用于第二级频谱管理装置执行的频谱分配与第一级频谱管理装置所执行的频谱分配之间的协调。
其中，分配单元101和生成单元102可以由一个或多个处理电路实现，该处理电路例如可以实现为芯片。频谱分配对象例如指的是要向其分配频谱的服务设备。以下将参照图1所示的共享频谱分配系统的示例对本申请的电子设备100进行详细描述。但是，应该理解，本申请的电子设备100并不限于应用于图1所示的共享频谱分配系统，而是可以适当地应用于各种具有多级频谱管理装置的共享频谱分配系统。
电子设备100例如可以位于第一级频谱管理装置上，或者可通信地连接到第一级频谱管理装置。例如，在待分配的频谱资源为3.5GHz频段上的频谱资源的情况下，第一级SM可以实现为频谱访问系统(Spectrum Access System，SAS)，第二级SM可以实现为共存管理器(Coexistence Manager，CxM)，频谱分配对象为公民宽带无线服务用户(Citizens Broadband Radio Service Device,CBSD)。其中，第一级SM和第二级SM可以实现为同一个实体，也可以实现为两个独立的实体。在待分配的频谱资源为5GHz频段上的频谱资源的情况下，第一级SM可以实现为中央控制器和协调器实体(Central Controller and Coordinator(C3) Instance)，频谱分配对象为无线接入系统/无线电局域网(Wireless Access Systems/Radio Local Area Network，WAS/RLAN)。
在一个示例中，分配单元101可以基于频谱分配对象以及频谱分配对象之间的干扰来分配频谱资源。例如，频谱分配的结果可以用可用频率、可用时间以及可用功率(例如，允许的最大功率)表示。
频谱分配对象之间的干扰例如可以基于信道模型计算得到。在一个示例中，两个频谱分配对象之间是否存在干扰基于这两个频谱分配对象的信号覆盖区域是否存在交叠来判断。例如，频谱分配对象的信号覆盖区域可以基于信号发射功率结合信道模型来估算得到。当两个频谱分配对象的信号覆盖区域有重叠时，表示这两个频谱分配对象之间会存在相互干扰。例如，分配单元101可以通过构造图(Graph)来进行频谱资源的分配。
图3示出了所构造的图的一个示意性示例。其中，顶点(vertex)用圆形表示，每个顶点代表一个或一组频谱分配对象，两个顶点之间存在边(edge)表示这两个或两组频谱分配对象的覆盖范围有重叠从而可能存在相互干扰，方格表示地理区域。在圆形中填充灰度来表示为相应顶点分配的频谱资源，不同的频谱资源用不同的灰度来区分。如图3所示，例如，为相互之间有边连接的两个顶点分配相互正交的频谱资源，而相互之间没有边连接的两个顶点可以分配非正交(比如，相同)的频谱资源。
分配单元101所获得的频谱分配结果可能不是具体到每一个频谱分配对象的。例如，对于第二级SM管理的第二集合的频谱分配对象，分配单元101可能获得第二集合整体可用的频谱资源，并且将由第二级SM根据本地信息来决定如何分配这些可用的频谱资源。如前所述，在不同的第二级SM被分配了非正交的频谱资源的情况下，可能会由于缺乏协调而产生资源使用冲突。
本实施例中设置了频谱协调信息来解决该冲突问题，除了频谱分配结果之外，第一级SM还向第二级SM提供该频谱协调信息。具体地，频谱协调信息例如用于第二级SM执行的频谱分配与第一级SM执行的频谱分配之间的协调。换言之，该频谱协调信息提供了第一级SM对第二级SM执行的频谱分配的进一步指导。
在一个示例中，频谱协调信息包括针对第二集合的频谱分配对象的频谱使用约束。频谱分配结果例如用分配给第二集合的资源池来表示，频谱使用约束提供了使用所分配的资源池中的频谱资源的约束条件，该约束条件可以是时间、空间或功率上的。
通过提供包含所分配的资源池的频谱分配结果和频谱使用约束，一方面，相对于具体到每个频谱分配对象的分配结果的形式，降低了信令开销、保护了频谱分配对象的隐私，并且给予了第二集合的频谱分配对象的资源分配的灵活性，在满足约束条件的前提下，频谱资源可以在第二集合内动态调整；另一方面，相对于仅指定频谱池的分配结果的形式，频谱使用约束可以提供多个第二集合间在该频谱池上共存使用的支持和性能保证。
例如，频谱使用约束可以包括如下中的一个或多个：特定地理区域中频谱分配对象的总的发射功率不超过预定功率；特定地理区域中同时进行发射的频谱分配对象的数目不超过预定值；特定频率上频谱分配对象的总的发射功率不超过预定功率；特定频率上同时进行发射的频谱分配对象的数目不超过预定值；特定地理区域中特定频率上频谱分配对象的总的发射功率不超过预定功率；特定地理区域中特定频率上同时进行发射的频谱分配对象的数目不超过预定值。
参照图3，特定地理区域可以是图3中划分的地理区域，但是并不限于此，例如也可以是任意单位面积的区域或用其他方式指定的地理区域。特定频率例如可以为单位频谱范围或者预先指定的频谱范围，等等。
此外，如图4所示，与图2相比增加了用斜纹方形表示的参考点，该参考点表示地理位置或地理区域。相应地，频谱使用约束还可以包括如下中的一个或多个：预定参考点处接收的来自频谱分配对象的功率不超过预定功率；预定参考点处特定频率上接收的来自频谱分配对象的功率不超过预定功率。
以上给出了频谱使用约束的一些示例，但是频谱使用约束并不限于此，而是可以根据实际要求来设置。
在另一个示例中，频谱协调信息可以包括针对第二集合的频谱分配对象的频谱分配规则的约束。这是因为，在采用某些频谱分配方法的情况下，即使所分配的资源池确定，该频谱分配方法的特点也会导致产生 不唯一的频谱分配结果。因此，通过提供对于频谱分配规则的约束，可以减少分配结果的范围，实现信息的一致性，或者实现以信息一致性为基础的共存管理。
频谱分配规则的约束与具体的频谱分配方法有关。例如，在采用基于图的频谱分配方法中，频谱分配规则的约束可以包括如下中的一个或多个：1)指定频谱分配对象的考察顺序并且指定待分配的单位频谱资源的考察顺序；2)指定频谱分配对象的特征集合以及该特征集合的频谱分配对象的频谱分配结果。
图5示出了采用1)的约束的频谱分配的一个示意图。其中，顶点和边的定义与图3相同。顶点旁的数字代表顶点对应的频谱分配对象被考察的顺序；灰度不同的方块代表不同的单位频谱资源，方块上的数字代表对应的频谱资源被考察的顺序；顶点用哪个灰度填充代表该灰度对应的频谱资源被配置给该顶点对应的频谱分配对象。考察顺序例如按照数字从小到大而从先到后。
可以看出，在指定了上述两个考察顺序之后，顶点的着色方案(即灰度填充方案)得以确定，即获得了确定的频谱分配结果。
图6示出了采用2)的约束的频谱分配的一个示意图。其中，标识了“×”的顶点为指定的特征集合。在如图6所示指定了这些特征集合的频谱分配对象的频谱分配结果之后，其他顶点的频谱分配结果也随之确定。
其中，特征集合可以根据约束的目标进行设定。例如，可以如下限定特征集合：特征集合是包含图中最少的顶点的集合，特征集合中顶点的频谱分配结果一旦确定，则整个图的频谱分配结果唯一确定。
应该理解，在采用其他的频谱分配方法时，可以存在其他形式的频谱分配规则的约束，以上约束并不是限制性的。
在又一个示例中，频谱协调信息包括第二集合中的频谱分配对象及其相互干扰关系的信息。换言之，第一级SM将其进行频谱分配所基于的干扰关系的信息提供给第二级SM，以实现共存管理。例如，频谱协调信息中包括的第二集合中的频谱分配对象为当前处于活动状态的频谱分配对象。
例如，可以用基于图论的抽象模型的形式来表示所述信息。即，第一级SM可以向第二级SM直接提供所建立的图，包括顶点集合以及边集合。
或者，可以用基于图论的抽象模型的生成方法的形式来表示所述信息。即，第一级SM可以向第二级SM提供建立图所需的信息的规则，包括顶点与频谱分配对象的映射关系、比如顶点对应于一个频谱分配对象还是频谱分配对象组成的集合以及图中的边的生成条件。其中，边的生成条件例如可以包括以下之一：所计算的顶点对应的频谱分配对象的信号覆盖区域有重叠；通过信道模型计算得到顶点对应的频谱分配对象间存在干扰；以及通过测量得到顶点对应的频谱分配对象间存在干扰。
此外，频谱协调信息还可以包括以上描述的三种信息中的任意两种或三种的组合，共同实现不同级SM之间频谱分配操作的协调。通过包括频谱协调信息，可以实现整个系统频谱分配的公平性和满足频谱分配效率的要求，同时兼顾信令开销和频谱分配的灵活性。
<第二实施例>
在本实施例中将详细描述频谱管理装置之间的信息交互的流程。
首先，图7示出了第一级SM与第二级SM之间的协调信息通知流程的示意图。例如，生成单元102生成协调信息更新请求，并且电子设备中的通信单元(图2中未示出)将该协调信息更新请求发送给第二级SM。通信单元例如可以实现为各种天线或天线阵列及其驱动电路，并且用于执行本申请中相关的信息发送和接收功能。
协调信息更新请求中可以包括针对第二集合的频谱分配对象的更新的频谱协调信息。应该注意，图7所示的协调信息通知流程可以与第一级SM通知频谱分配(重分配)结果的流程同时执行，也可以在频谱分配结果(例如为分配的资源池)没有发生改变的情况下单独执行。在后一种情况下，仅更新频谱协调信息。
如图7所示，在第二级SM接收到协调信息更新请求时，从中获取频谱协调信息，并使用该频谱协调信息来更新本地的频谱协调信息，进而基于更新的频谱协调信息来进行本地频谱分配。接下来，第二级SM 向第一级SM发送协调信息更新响应，作为对协调信息更新请求的回复。
图8示出了第一级SM与第二级SM之间的频谱使用冲突处理流程的示意图。例如，第二级SM向管理该第二级SM的第一级SM发送冲突处理请求，并且由第一级SM作出处理和响应。其中，频谱使用冲突可以由第二级SM管理的频谱分配对象、即服务设备上报。例如，当请求第一级SM处理冲突为优先方案，或者第二级SM之间无法协商(比如没有信息接口，或者无法发现可协商的第二级SM)，或者第二级SM之间协商无法解决该冲突时，第二级SM可以请求第一级SM进行冲突处理。
该冲突处理请求中可以包括受害(Victim)频谱分配对象(即受害服务设备，所谓受害即受到严重的同频或者邻频干扰从而影响其正常通信)的信息。第一级SM在不影响当前服务的服务设备的情况下，对该冲突进行处理，并向第二级SM发送冲突处理响应作为对冲突处理请求的回复。
图9示出了第一级SM与第二级SM之间的协调信息调整流程的示意图。第二级SM向第一级SM发送协调信息调整请求，其中包含作为调整目标的调整信息。第一级SM在接收到协调信息调整请求之后，检查调整目标能否被满足，例如检查在满足调整目标的情况下当前服务的服务设备是否会受到影响，系统整体频谱使用效率是否得到提升，等等。接着，第一级SM向第二级SM发送协调信息调整响应，即回复调整请求的结果。该流程例如用于各第二级SM根据本地信息获得更好的频谱协调信息设定，以进一步提升系统频谱使用效率。
此外，第一级SM还可以向其他第一级SM提供本第一级SM的频谱协调信息。其中，所提供的频谱协调信息可以为第一集合中所有或部分频谱分配对象的频谱协调信息。例如，可以仅提供涉及两个SM的管理区域相互交叠部分中的频谱管理对象的频谱协调信息。该频谱协调信息可以具有第一实施例中所述的各种形式。并且，该频谱协调信息在广泛的含义上还可以包含频谱分配结果比如所分配的资源池。
图10示出了两个第一级SM之间的协调信息共享流程的示意图。该流程用于各第一级SM独立做出所管理的频谱分配对象(即，服务设备)的频谱分配，同时协调这些频谱分配对象与分布在相同地理区域中的由 其他第一级SM所管理的其它频谱分配对象之间的频谱共享。
如图10所示，第一级SM(1)向第一级SM(2)发送协调信息更新请求，其中包含第一级SM(1)更新的频谱协调信息，以请求第一级SM(2)接收该更新。第一级SM(2)在接收后向第一级SM(1)发送响应，确认频谱协调信息的更新。相应地，第一级SM(1)从第一级SM(2)获得频谱协调信息的更新确认。图10所示的流程可以被称为推送型(Push Type)的流程。
图11示出了两个第一级SM之间的协调信息共享流程的另一个示意图。其中，第一级SM(2)向第一级SM(1)发送协调信息更新请求，请求第一级SM(1)更新其频谱协调信息。第一级SM(1)响应于该协调信息更新请求来发送协调信息更新回复，其中包含其更新的频谱协调信息。图11所示的流程可以被称为牵引型(Pull Type)的流程。在本申请的实施例中，两个第一级SM的信息交互接口间的信息共享方式可以支持两种类型的流程中的至少一个。
此外，在发生频谱使用冲突时，生成单元102还可以生成冲突处理请求，以提供给其他第一级SM并且由其他第一级SM处理该冲突。图12示出了两个第一级SM之间的频谱使用冲突协商流程的一个示意图。该流程可以用于各第一级SM之间协调处理遵循所交互的频谱协调信息前提下的频谱使用冲突问题。频谱使用冲突可能由第一级SM所管理的服务设备或者第二级SM上报。
如图12所示，第一级SM(1)发现频谱使用冲突，生成冲突处理请求，并且向第一级SM(2)发送给冲突处理请求，该请求中可以包括受害频谱分配对象的信息。第一级SM(2)接收该冲突处理请求，并根据其中包含的信息进行冲突处理，例如尝试在频谱协调信息不变的情况下解决该冲突。随后，第一级SM(2)将冲突处理的结果作为对冲突处理请求的响应发送给第一级SM(1)。
在进行冲突处理时，可以执行一次或多次图12所示的频谱使用冲突协商流程。进一步地，如果所交互的频谱协调信息无法解决冲突，则可以执行协调信息调整的流程。例如，生成单元102生成协调信息调整请求，以提供给其他第一级SM并且由其他第一级SM处理该请求。协调信息调整请求中可以包括对其他第一级SM的频谱协调信息的调整目标。
图13示出了两个第一级SM之间的协调信息调整流程的示意图。除了用于解决频谱使用冲突之外，协调信息调整的目的还可以是使得第一级SM适应新的服务设备业务需求，或者任何其他目的。
如图13所示，第一级SM(1)向第一级SM(2)发送协调信息调整请求，其中包含第一级SM(2)的频谱协调信息的调整目标。第一级SM(2)检查该调整目标是否能够得到满足，例如在调整目标能够得到满足的情况下进行相应的调整。随后，第一级SM(2)向第一级SM(1)发送协调信息调整响应，以报告调整结果。
其中，检查调整目标能否得到满足的前提例如可以包括不影响当前服务的服务设备，提升系统整体频谱使用效率等等。
此外，通过上述描述，还提供了一种用于无线通信的电子设备，该电子设备包括：分配单元101，被配置为针对第一级SM所管理的第一集合的频谱分配对象，分配频谱资源；以及生成单元102，被配置为针对第一集合的频谱分配对象，生成频谱协调信息以提供给其他第一级SM，频谱协调信息用于第一级SM与其他第一级SM所执行的频谱分配之间的协调。
其中，频谱协调信息可以包括第一集合的频谱分配对象的频谱使用约束的信息；以及/或者，频谱协调信息可以包括频谱分配规则的约束；以及/或者，频谱协调信息可以包括频谱分配对象及其相互干扰的信息。例如，该电子设备可以用于只有一级的共享频谱分配系统的频谱管理装置侧。此外，第一级SM之间还可以交互各自管理的第一集合的频谱分配对象所分配的频谱资源。
此外，提供给其他第一级SM的频谱协调信息可以是第一集合中的全部频谱分配对象的频谱协调信息，也可以是第一集合中的一部分频谱分配对象比如两个第一级SM的覆盖区域的交叠部分中的频谱分配对象的频谱协调信息。
另外，该电子设备也可以与其他第一级SM之间执行前述的各种流程，比如协调信息共享流程、频谱使用冲突协商流程、协调信息调整流程等等，在此不再重复。
<第三实施例>
图14示出了根据本申请的另一个实施例的用于无线通信的电子设备200的功能模块框图，如图14所示，电子设备200包括：获取单元201，被配置为获取针对第二级SM所管理的第二集合的频谱分配对象的频谱协调信息，该频谱协调信息用于第二级SM执行的频谱分配与位于第二级SM管理的上层的第一级SM所执行的频谱分配之间的协调；以及执行单元202，被配置为至少基于频谱协调信息执行第二集合中的频谱分配对象的频谱分配。
其中，获取单元201和执行单元202可以由一个或多个处理电路实现，该处理电路例如可以实现为芯片。电子设备200例如可以位于第二级SM上或者可通信地连接到第二级SM。例如，参照图1所示的共享频谱分配系统，电子设备200可以位于或者可通信地连接到SM 2 1或SM 2 1上。
本实施例中所述的频谱协调信息与第一实施例中所述的频谱协调信息具有相同的定义。并且，第二级SM还从第一级SM接收频谱分配结果比如第一级SM分配给第二级SM的资源池。
例如，频谱协调信息可以包括以下中的一个或多个：针对第二集合的频谱分配对象的频谱使用约束；针对第二集合的频谱分配对象的频谱分配规则的约束；以及第二集合中的频谱分配对象及其相互干扰关系的信息。关于这些频谱协调信息的描述在第一实施例中已经详细给出，在此不再重复。
执行单元202至少基于所获得的频谱协调信息来执行本地的频谱分配，例如，将第一级SM分配给第二级SM的频谱池中的频谱资源在遵循该频谱协调信息的条件下分配给第二级SM所管理的各个频谱分配对象。
在一个示例中，执行单元202还基于本地传输环境和测量结果来进行频谱分配。这样，可以以更符合实际干扰状况的方式来分配频谱资源，从而提高频谱使用效率。
执行单元202还被配置为在发生频谱使用冲突的情况下生成冲突处理请求，以提供给其他第二级SM或第一级SM。其中，冲突处理请求中可以包括受害的频谱分配对象的信息。
在第二实施例中已经描述了第二级SM向第一级SM发送冲突处理请求并且由第一级SM进行冲突处理的流程的示例，下面将参照图15来描述在第二级SM之间执行的冲突处理的流程的示意图。其中，第二级SM(1)检测到发生频谱使用冲突，生成冲突处理请求并且将该冲突处理请求发送到第二级SM(2)；第二级SM接收到该冲突处理请求后根据其中包含的信息进行冲突处理，例如在尝试保持频谱协调信息不变的情况下进行冲突处理；随后，第二级SM(2)将冲突处理的结果作为对冲突处理请求的响应发送给第二级SM(1)。
在进行冲突处理时，可以执行一次或多次图15所示的频谱使用冲突协商流程。此外，图15中第二级SM(1)和第二级SM(2)的角色可以互换，即第二级SM(2)向第二级SM(1)发送冲突处理请求并且由第二级SM(1)执行冲突处理。
进一步地，如果基于当前的频谱协调信息无法解决冲突，则可以执行协调信息调整的流程。例如，执行单元202生成协调信息调整请求，以提供给其他第二级SM或第一级SM并且由其他第二级SM或第一级SM处理该请求。关于向第一级SM发送协调信息调整请求的示例已经在第二实施例中进行了描述，在此不再重复。
图16示出了两个第二级SM之间的协调信息调整流程的示意图。协调信息调整请求中可以包括对其他第二级SM的频谱协调信息的调整目标。除了用于解决频谱使用冲突之外，协调信息调整的目的还可以是使得第二级SM适应新的服务设备业务需求，或者任何其他目的。
如图16所示，第二级SM(1)向第二级SM(2)发送协调信息调整请求，其中包含第二级SM(2)的频谱协调信息的调整目标。第二级SM(2)检查该调整目标是否能够得到满足，例如在调整目标能够得到满足的情况下进行相应的调整。随后，第二级SM(2)向第二级SM(1)发送协调信息调整响应，以报告调整结果。
其中，检查调整目标能否得到满足的前提例如可以包括不影响当前服务的服务设备，提升系统整体频谱使用效率等等。
此外，执行单元202还可以被配置成为频谱分配对象进行带宽扩展。例如，在基本的频谱分配之外，在不影响已有的频谱分配结果的条件下，为频谱分配对象进行展。
<第四实施例>
为了便于理解，在本实施例中将给出本申请的技术在3.5GHz频段和5GHz频段上的应用的实例。但是，应该理解，这仅是示例性的，而非限制性的。
第一实例
WINN Forum(WINNF)组织制定的频谱访问系统(SAS)研究3.5GHz频段上多系统间的共存管理。在美国，3.5GHz频带一直用于国防部(Department of Defense,DoD)雷达系统，目前联邦通信委员会(Federal Communications Commission,FCC)在讨论将该频段通过频谱共享的方式用于商用。该共享系统是SAS的一部分，包含三个等级：授权用户(incumbent user)代表最高等级，授权用户包含上述DoD雷达系统、固定卫星服务(Fixed Satellite Service,FSS)以及有限时间内的特权陆地无线业务(grandfathered terrestrial wireless operations)；其它统称公民宽带无线服务用户(CBSD)，进一步包含优先访问许可证(priority access license,PAL)以及普通授权访问(General Authorized Access,GAA)两个等级。在频谱使用上，需要保护授权用户不受到来自CBSD的有害干扰，并且需要保护PAL不受到来自GAA的有害干扰。公民宽带无线服务(Citizens Broadband Radio Service,CBRS)以人口普查区(census tract)为单位进行资源分配，优先访问许可证可以使用3550-3650MHz范围内的频谱，以10MHz为单位以3年为期限发放，每个人口普查区的所有PAL所占总频谱不超过70MHz，其中每个PAL的频谱不超过40MHz。GAA在保证不对高级别用户产生有害干扰的前提下，可以使用3550-3700MHz范围内的频谱。用于资源管理的逻辑实体主要包括SAS以及域代理(Domain Proxy，DP)，如图17所示，其中域代理代表个体CBSD或者网络CBSD与SAS进行交互为CBSD获得服务。当然，CBSD也可以不通过域代理直接与SAS进行交互获得服务。
CBRS Alliance(CBRS-A)组织制定技术规范(Technical Specification，TS)提供不同CBSD之间的共存。这些CBSD的物理实现是LTE变体，例如LTE-TDD(FS2)、LTE-LBT(FS3)。该TS主要关注CBSD中的GAA共存需求。图18给出了该TS中多个概念之间的 关联。其中，所有在SAS注册的CBSD用户总体分为属于CBRS-A管理的共存组(Coexistence Group,CxG)，以及非CBRS-A管理的共存组。这些共存组之间的频谱分割以及分配是由WINNF组织的SAS负责；CBRS-A管理的共存组中，逻辑实体共存管理器(CxM)负责遵循SAS的规则，管理CxG中GAA用户之间的共存。此外，根据物理实现类型，进一步将CBSD分为CBRS-A LTE-TDD Config-A、CBRS-A LTE-TDD Config-B以及CBRS-A LTE-LBT。在每种类型中，例如CBRS-A LTE-TDD Config-A中，进一步可能将CBSD分为多个干扰协调组(Interference Coordination Group,ICG)。属于相同ICG的CBSD之间可以管理相互间干扰，因此不需要保持频谱正交化。在每个ICG中，进一步可能将CBSD分为多个公共信道组(Common Channel Group,CCG)。属于相同CCG的CBSD请求相同的基本信道分配(Primary Channel Assignment)。图19给出了获得CBRS-A认证的CBSD向SAS上报成员资格(Membership)的流程的示意图。获得CBRS-A认证的CBSD通过该流程向SAS注册，其中，CBSD向SAS报告其所属CxG的成员资格，可选地，如图19中的虚线所示，CBSD还向SAS报告其所属ICG、CCG的成员资格。
在该实例中，第一级频谱管理装置实现为SAS，第二级频谱管理装置实现为CxM，频谱分配对象为CBSD。其中，SAS负责为CxG提供频谱分配。SAS在决定频谱可用性时可以采用基于图的过程，具体的频谱分配方法可以在WINNF中制定。例如，SAS依据CBSD信息建立Graph S，以进行频谱分配。
CxM为CBSD进行基本信道分配(Primary Channel Assignment)，CBRS-A CxG由一个CxM管理。参见图20，CxM初始化时获得SAS提供的一组由该CxM管理的处于活动状态的CBSD，以及用于这些CBSD的一个频谱池。可选地，如图20中的虚线所示，CxM还从SAS获得这些CBSD所属的ICG或CCG的成员资格。此外，当应用本申请的技术时，CxM还从SAS获得针对这些CBSD的频谱协调信息(图中未示出)。
CxM根据SAS提供的信息，结合本地的传输环境和无线测量结果来构造新的图Graph M。Graph M相比Graph S可以进一步地移除一些边，从而改变图中的连通集(Connected Set)。因此，CxM所构造的图Graph M 基于更实际的模型假设，考虑了不同的物理层配置(例如TDD配置，比如LTE-TDD对LTE-LBT)，且按照连通集对频谱池进行分割。
CxM在进行频谱分配时，对每个连通集及其关联的频谱池独立进行频谱分配。进一步，为了保证LTE-TDD CBSD的共存，CxM考虑不同CCG之间覆盖的重叠，建立LTE-TDD重叠图Graph CP。其中，每个顶点代表一个CCG分割(CCG Partition)。CCG分割是CCG的一个子集，CCG分割之间没有覆盖范围的重叠；顶点间连一条边，表示对应的CBSD的覆盖之间有重叠；如果两个顶点中的CBSD属于相同的ICG，则这两个顶点间无边相连。
CxM基于Graph CP进行基本信道分配，对其中的连通集独立分配。例如，通过对图的染色来进行频谱分配，期望用最少的颜色对每个连通集染色(该颜色数目记作N)，即期望用最少的频谱资源来满足连通集中各CBSD的频谱要求；连通集对应的可用频谱池被正交均分成N个基本信道，每个顶点分得其颜色对应的信道的频谱资源。
此外，CxM还可以在基本信道分配之外，为CBSD进行带宽扩展。例如，带宽扩展需满足以下要求：该带宽扩展不影响已有的基本信道分配结果的正常使用；该带宽扩展不影响对于授权用户和PAL用户的干扰保护要求。
在该实例中，通过应用本申请的技术，即SAS向CxM提供频谱协调信息，可以协调SAS的频谱分配和CxM执行的本地频谱分配，从而兼顾整个系统频谱分配的公平性、灵活性和频谱分配效率。
第二实例
开发用于5G宽带系统的技术是欧洲委员会(European Commission)的目标之一。研究成果包括宽带无线接入网络(Broadband Radio Access Networks，BRAN)的项目：WAS/RLAN在5GHz频段上的中央协作。
该系统中用于管理的逻辑实体叫做C3(Central Controller and Coordinator,C3)，其具体化的物理实体叫做C3实体。C3实体的实现可以是分布式互联互通的多个C3实体，通过信息交互实现对管理对象的中央协调。
在将本申请的技术应用于5G宽带系统时，第一级SM可以实现为 C3实体；频谱分配对象可以实现为WAS/RLAN。
以上虽然给出了3.5GHz和5GHz的实例，但是这并不是限制性的，本申请的技术对其它非授权频段同样适用。
<第五实施例>
