Description

用于无线通信的电子设备、方法和计算机可读存储介质
本申请要求于2018年3月7日提交中国专利局、申请号为201810186035.7、发明名称为“用于无线通信的电子设备、方法和计算机可读存储介质”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，具体地涉及一种频谱接入系统的共存协调技术，更具体地涉及用于无线通信的电子设备、方法和计算机可读存储介质。
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。这些频谱资源对于LTE等无线通信业务而言是非授权频段，比如3.5GHZ、5GHz和毫米波频段等。
例如，美国联邦通讯委员会(Federal Communication Commission，FCC)宣布民用宽带无线电服务频段(Citizen Broadband Radio Service，CBRS)将对商用用户开放，该频段的频谱范围为3550MHz-3700MHz。FCC提出了一种三层频谱接入系统框架：现有(Incumbent access,IA)用户、优先访问许可(Priority Access License,PAL)用户和一般授权访问(General Authorized Access,GAA)用户。这种三层频谱共享框架由频谱接入系统(Spectrum Access System,SAS)进行频谱管理，协调现有军用雷达、卫星地球站和各种新型商业用户之间的频谱接入。CBRS 联盟(CBRS Alliance)正在制定相关的标准或技术规范。
在SAS系统中，一组民用宽带服务设备(Citizen Broadband Service Device，CBSD)可以由共存管理器(Coexistence Manager,CxM)统一管理。由于不同的CxM之间是相互独立的，当不同CxM所管理的次用户设备使用相同频道时，可能会对主用户或其他共享频谱的次用户(例如IA、PAL或GAA用户)造成有害干扰，即产生非协作干扰问题。

在此，还需要说明的一点是，为了避免因不必要的细节而模糊了本发明，在附图中仅仅示出了与根据本发明的方案密切相关的设备结构和/或处理步骤，而省略了与本发明关系不大的其他细节。
<第一实施例>
如前所述，在使用频谱资源的次系统(次用户)由不同的用于频谱管理的管理装置(比如CxM)进行管理时，可能会出现非协作干扰。因此，期望对非协作干扰进行快速、高效地检测，以便有效地保证各个通信系统的通信质量。
图1示出了根据本申请的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1所示，电子设备100包括：获取单元101，被配置为从管理区域中的监测节点获取监测节点针对指定信道的监测结果，其中，指定信道为可用频谱资源上的一个或多个信道，并且指定信道是基于节点的历史数据估计的存在非协作干扰的可能性最高的一个或多个信道；以及判断单元102，被配置为基于监测结果判断指定信道上是否存在 非协作干扰。
其中，获取单元101和判断单元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。电子设备100例如可以位于频谱管理装置侧，或者可通信地连接到频谱管理装置。频谱管理装置例如可以实现为频谱访问系统(Spectrum Access System，SAS)、共存管理器(Coexistence Manager，CxM)、地理位置数据库(geographic location database，GLDB)或者中央控制器和协调器实体(Central Controller and Coordinator(C3)Instance)等。
其中，管理区域为电子设备100所在的频谱管理装置的管理区域，管理区域中可能存在多个用户。这里所述的用户例如指利用频谱管理装置分配的频谱资源进行通信的次系统，次系统中可以包括基站和用户设备。
此外，虽然图中未示出，但是电子设备100还包括通信接口，用于与其他频谱管理装置以及/或者所管理的用户间进行通信。通信接口可以利用各种有线或无线通信接口来实现。
在本申请中，监测节点指的是具有无线电监测能力的设备，可以是次系统中的基站或用户设备。在频谱管理装置所管理的用户可以使用的可用频谱资源中，一般存在多个信道，为了解决信令开销和测量开销，监测节点可以仅对指定信道进行监测。指定信道为所有信道中最可能出现非协作干扰的一个或多个信道，其中，该可能性是基于节点的历史数据而估计的。
节点的历史数据例如包括该节点使用过的各个信道的历史记录，尤其是与非协作干扰有关的历史数据。通过对这些历史数据进行统计，可以准确地估计每个信道上出现非协作干扰的统计概率，并且预测每个信道上可能出现非协作干扰的概率，从而仅选择特定信道进行监测。
这样，通过有针对性地对指定信道进行监测，一方面可以快速发现非协作干扰的情形，另一方面可以节省测量和计算资源以及信令开销。
图2示出了电子设备100的另一个示例的功能模块框图，除了图1所示的各个单元之外，该电子设备100还包括：选择单元103，被配置为基于监测节点与该监测节点的至少部分邻居节点对于各个信道的历史使用状况来对信道进行预测评分，例如，当某一信道上出现非协作干扰的 频率越高时，该信道的评分越高；以及选择评分最高的N个信道作为指定信道。其中，N可以为预定指定的正整数以及/或者所选择的信道的评分超过预定评分阈值。
类似地，选择单元103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。
其中，邻居节点为位于监测节点的监测范围内的节点，使用邻居节点对于信道的历史使用状况来进行预测评分可以提高评分的准确性，进而提高非协作干扰检测的准确性，还可以更好地应对可能存在的隐节点问题。
在一个示例中，假设监测节点的感知半径为R，选择在监测节点的感知范围内的共存节点作为候选邻居节点集(candidate neighbor set)，如下式(1)所示：
Candidate Neighbor Set(s)＝{U i|d(U i，s)＜R,i＝1,2,3…N}     (1)
其中，d(U i，s)为第i个共存节点(比如CBSD)与监测节点s之间的距离。
选择单元103还被配置为对候选邻居节点集中的邻居节点进行选择，并使用选择出的邻居节点的历史数据来进行预测评分。
例如，选择单元103被配置为：基于对各个信道的历史使用状况，获得监测节点与该监测节点的各个邻居节点对于各个信道的历史评分；基于该历史评分计算监测节点与各个邻居节点之间的评分相似度，并选择评分相似度满足预定条件的邻居节点作为所述至少部分邻居节点；以及根据所述监测节点和所选择的邻居节点的历史评分来对信道进行预测评分。
假设u和v为两个共存节点，这两个节点对各个信道的评分向量分别用r u和r v表示，||r u||与||r v||为向量的模，则这两个节点间的评分相似度例如可以为：
Figure PCTCN2019076931-appb-000001
应该理解，式(2)为采用了相似度测量的余弦距离公式，这仅是一个示例，还可以采用其他计算方式，比如皮尔逊相关系数等。
例如使用上式(2)来计算监测节点与其邻居节点(即，候选邻居节点集中的节点)之间的评分相似度，并且选择相似度在某一设定区间[S low,S high]内的节点作为监测节点的邻居节点，这些被选择的节点构成邻居节点集(neighbor set)，如下式(3)所示：
Neighbor Set(s)＝{U i|S low＜s(U i，s)＜S high,i∈Candidate Neighbor Set(s)}      (3)
其中，s(U i，s)为第i个共存节点与监测节点s之间的评分相似度。此外，相似度的设定区间也可以为高于某一预定值或低于某一预定值。
接下来，可以使用监测节点和所选择的邻居节点的历史评分来计算信道的预测评分，例如，可以通过对监测节点和所选择的邻居节点对于各个信道的历史评分求平均来估计预测评分，如下式(4)所示。
Figure PCTCN2019076931-appb-000002
其中，k代表包括监测节点s和所选择的k-1个邻居节点在内的所有节点，R ic为各个节点对于信道c的历史评分，R(s,c)是监测节点s对信道c的预测评分。
其中，可以采用各种方式获得信道的历史评分，图3示出了一个作为示例的信道评分表，其中，评分值的取值范围为0～5，按照非协作干扰在该信道上出现过的统计概率进行评分。应该理解，这仅是一个示例，并不是限制性的。
监测节点和所选择的邻居节点对于各个信道均计算了该信道的历史评分值，例如采用式(4)所示的方式来计算出该信道的预测评分。
接下来，选择评分最高的N个信道作为要进行监测的指定信道。其中，N可以为预定指定的正整数，也可以是通过选择评分高于预定评分阈值而获得的信道的数目。
具体地，可以对信道的预测评分进行排序，根据需要设定预定评分阈值，并且选择预测评分超过该阈值的前若干个信道作为指定信道。
监测节点对N个指定信道逐一进行检测，分别得到N个信道上检测到的累积干扰值，判断单元102通过将该累积干扰值与预定干扰容限进行比较来判断指定信道上是否存在非协作干扰。
应该注意，干扰容限可以是一个动态可变的干扰阈值而不是一个固定值，干扰容限例如取决于共存用户设备的发射频谱模板、接收机灵敏度以及对带外干扰抑制的要求以及共存用户的服务质量(Quality of Service，QoS)比如信干噪比(Signal to Interference and Noise Ratio，SINR)门限，因此，干扰容限可能会随具体工作频率、共存用户设备的空间位置以及共存用户的QoS门限的改变而变化。
作为一个示例，判断单元102可以基于所监测的指定信道的干扰噪声比(Interference and Noise Ratio，INR)来判断指定信道上是否存在非协作干扰。例如，判断单元102可以通过判断所监测的INR与在不存在非协作干扰的情况下所计算的INR之间的差是否超过预定阈值，来判断指定信道上是否存在非协作干扰。如果所计算的INR之间的差超过预定阈值，则判断指定信道上存在非协作干扰。应该理解，差仅是一个示例，还可以采取其他形式的参数计算，比如计算所监测的INR与在不存在非协作干扰的情况下所计算的INR之间的方差等等。应该理解，INR是针对每一个指定信道而言的。
此外，判断单元102还可以通过将所监测的INR与基于节点的历史数据设置的INR阈值相比较，来判断指定信道上是否存在非协作干扰。例如，可以比较所监测的INR与基于节点的历史数据设置的INR阈值之间的差或方差等等。
此外，作为一个示例，具有监测能力(即，无线感知能力)的邻居节点也可以参与非协作干扰的检测或测量，其检测结果也提供给判断单元102来用于判断，从而进一步提高非协作干扰检测的准确性。
在另一个示例中，为了进一步降低系统开销，选择单元103还可以被配置为基于管理区域中的节点的如下参数中的一个或多个来选择作为监测节点的节点：节点的位置、节点的监测能力、节点的负荷因子。例如，选择单元103可以根据节点的负荷因子来选择监测节点，比如选择负荷较小的节点作为监测节点。选择单元103还可以基于节点的监测能力来选择监测节点，比如选择具有监测能力或者监测能力强的节点作为 监测节点。
示例性地，选择单元103可以选择靠近容易产生非协作干扰的位置处或靠近重要位置处的、具有监测能力、且负荷较小的节点作为监测节点。
上述位置可以统称为关键位置，即，关键位置是管理区域中要进行非协作干扰监测的位置。关键位置例如包括如下位置中的一个或多个：主用户的位置、受保护的次用户的位置、不同共用信道组之间的交叠区域。其中，该交叠区域是对非协作干扰敏感的位置。
例如，选择单元103被配置为基于各个节点与关键位置之间的有效距离来选择监测节点，其中，有效距离基于节点与关键位置之间的物理距离和节点的负荷因子获得。通过基于有效距离来选择监测节点，可以同时考虑节点的位置以及负荷情况。例如，选择单元103可以选择距各个关键位置的有效距离最小的节点作为针对该关键位置的监测节点。
下面给出一个基于有效距离矩阵的监测节点选择的具体示例。假设选择了M个关键位置，其中，第j个关键位置的坐标表示为P j＝(X j，Y j)，则M个关键位置组成的关键位置集可以表示为：
P＝{P 1,P 2......P M}＝{(X 1,Y 1),(X 2,Y 2)......(X M,Y M)}         (5)
如果管理区域中有N个具有监测能力的节点(比如CBSD节点)，第i个节点的位置坐标U i＝(x i，y i)，用户节点的集合可以用下式(6)表示：
U＝{U 1,U 2......U N}＝{(x 1,y 1),(x 2,y 2)......(x N,y N)}       (6)
第i个节点与第j个关键位置之间的有效距离d ij (*)为：
Figure PCTCN2019076931-appb-000003
其中，d ij为第i个节点与第j个关键位置之间的物理距离，η i为第i个节点(如基于LTE-TDD的CBSD设备)的负荷因子(load factor，0≤η≤1)。d ij的定义例如下式(8)所示：

有效距离矩阵D的第i列向量表示N个节点到第i个关键位置的有效距离向量，例如，如果第i列向量中最小值为d ij，则第j个节点被选作监测节点。按照这种方式，从N个节点中选出M个节点作为监测节点，形成监测节点集。
此外，如果考虑节点的自身负荷问题，当一个节点被选择为某一关键位置的监测节点时，在其余关键位置的监测节点选择中则不再考虑该节点，以使得一个监测节点只用于监测一个关键位置。
可以理解，在选择监测节点所基于的因素与节点的负荷有关的情况下，由于监测节点自身的负荷是随着时间发生变化的，因此需要动态更新监测节点集。换言之，为了进一步优化监测节点的选择，选择单元103可以被配置为根据节点的负荷的变化来动态选择所述监测节点。
在一个示例中，选择单元103还被配置为生成包括指示被选择为监测节点的信息以提供给所选择的监测节点。这样，被选择的监测节点将执行监测操作。可选地，选择单元103还可以被配置为获取来自监测节点的响应。该响应例如表示该监测节点是否同意作为监测节点工作。
此外，获取单元101还被配置为从监测节点获取监测结果。其中，获取单元101可以被配置为周期性地获取该监测结果或者在满足预定条件的情况下获取该监测结果。例如，监测节点可以对监测结果进行初步判断，仅在很可能存在非协作干扰的情况下才进行监测结果的报告。监测结果可以包括监测节点的标识以及具体的监测数据。具体的监测数据 例如可以包括测量的INR、时间戳、信道索引等。
相应地，通信单元执行上述信息的发送以及上述响应和监测结果的接收。
根据本实施例的电子设备100能够通过根据历史数据来选择出现非协作干扰的可能性高的信道并指示监测节点对这些信道进行监测，可以快速准确地监测到非协作干扰。此外，电子设备100通过选择特定的节点作为监测节点，保证了监测的正常执行和监测结果的有效性。
<第二实施例>
图4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，除了图1中所述的获取单元101和判断单元102之外，电子设备200还包括：处理单元201，被配置为在监测到非协作干扰的情况下，提取该非协作干扰的特征。
类似地，该处理单元201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。
非协作干扰的特征例如可以包括如下中的一个或多个：干扰带宽，干扰噪声比INR，干扰信号类型，非协作干扰出现的时间。
例如，可以根据监测到的INR随时间的变化曲线，获取出现非协作干扰的具体时间。由于频谱管理装置中记录了各个次用户的信息(包括位置、设备类型等)以及使用频谱的记录，因此可以通过查询这些记录来获取造成非协作干扰的次用户的信息。
处理单元201还被配置为基于非协作干扰的特征，进行非协作干扰的处理以消除该非协作干扰。
在一个示例中，这些处理例如可以包括以下中的一个或多个操作：调整受到非协作干扰的影响的用户的频谱或波束；向频谱管理装置请求额外的频谱资源。在该示例中，由受到非协作干扰的影响的用户对自身的频谱使用进行调整，即避开存在非协作干扰的频谱资源(比如频谱或波束)。
例如，电子设备200位于CxM侧，在发现某一信道上存在非协作干扰时，处理单元201提取该非协作干扰的特征并获得受到影响的次用户 的信息，在频谱资源充裕的情况下，调整该次用户所使用的频道或波束以避开非协作干扰。在该次用户的功率发射等级较低的情况下，可以尝试提高其功率发射等级。此外，在没有空闲频谱资源的情况下，处理单元201向SAS请求额外的频谱资源，SAS例如在干扰重叠图中彼此相连的最大顶点数小于其能提供的最大信道数目时、即频谱资源充裕时，则为该CxM分配额外的可用频谱资源。
为了便于理解，图5示出了包括电子设备200的CxM与共存用户设备CBSD以及与SAS之间的信息流程的示意图。
如图5所示，CBSD向CxM发送注册请求，其中可以包括CBSD的相关信息比如位置信息、请求频段、发射功率、监测能力等，CxM在接收到来自多个CBSD的注册请求之后，向SAS发送批量注册请求，SAS相应地发送批量注册响应。此外，SAS根据该请求计算要分配给CBSD的可用频谱资源，CBSD获取到可用频谱资源后，将这些信息发送给CxM，由CxM负责管理(图5中未示出)。
如第一实施例中所述，CxM例如根据节点的位置、监测能力、负荷因子等选择特定的节点作为监测节点，并且向这些监测节点发送注册响应。如图5中的虚线所示，可选地，监测节点还可以向CxM发送响应表示确认同意作为监测节点。接下来，针对每个监测节点，CxM例如根据历史数据选择要进行监测的N个最可能存在非协作干扰的指定信道，并且将这N个指定信道的信道索引包括在监测指示中发送给相应的监测节点。监测节点在完成监测时向CxM发送监测报告，其中可以包括监测节点的标识和监测数据。CxM根据监测报告判断是否存在非协作干扰，并且在存在非协作干扰的情况下对该非协作干扰进行处理。
图5中示出了CxM对受到非协作干扰的影响的用户的频谱使用进行调整的示例。具体地，CxM可以向SAS请求额外的频谱，在SAS的频谱充裕的情况下，SAS为CxM分配额外的可用频谱，从而CxM可以将该额外的可用频谱分配给受到非协作干扰的影响的用户使用。此外，CxM还可以通过调整受到非协作干扰的影响的用户的波束或者提高该用户的功率等级来避开或减轻非协作干扰。
可以理解，以上SAS所分配的额外的可用频谱也可以是借调自同区域的其他SAS的可用频谱。具体地，在同区域有不同的SAS的情况下， SAS分别管理不同的频段，因此，当一个SAS(称为第一SAS)的频谱短缺时，其可以向其他SAS中的第二SAS临时借调可用频谱，而当第二SAS也需要该频谱时，则第一SAS将命令使用该频谱的次用户立即停止使用，而将该频谱资源归还给第二SAS。
在另一个示例中，电子设备200位于SAS侧，则处理单元201在频谱资源充裕的情况下，为上述次用户分配其他可用的频谱资源。在频谱资源不充裕的情况下，SAS可以向同区域的其他SAS(下文中也称为对等SAS)借调频谱。
图6示出了CBSD与服务SAS之间和服务SAS与对等SAS之间的信息流程的示意图。如图6所示，在该示例中，由SAS执行监测节点的选择和指定信道的确定，并且在CBSD和其服务SAS之间进行了与图5中的CBSD和CxM之间类似的信令交换，在此不再赘述。不同之处在于，在服务SAS确定存在非协作干扰且自己没有充裕的频谱资源时，服务SAS向对等SAS借调频谱资源并将借调的频谱资源分配给受非协作干扰影响的用户。作为非协作干扰处理响应，类似地，也可以采用以上参照图5中所述的通过调整受到非协作干扰的影响的用户的波束或者提高该用户的功率等级来避开或减轻非协作干扰的方式。
可替选地，还可以对造成非协作干扰的用户的频谱使用进行调整。在这种情况下，例如，处理单元201可以被配置为生成提供给频谱管理装置的处理请求，以请求频谱管理装置进行非协作干扰的处理，该处理请求包括非协作干扰的特征，处理单元201还被配置为从频谱管理装置获取响应于该处理请求的处理结果，处理结果例如包括以下中的一个或多个：为产生非协作干扰的次用户分配了额外的频谱资源；调整了产生非协作干扰的次用户的频谱或波束；调整了产生非协作干扰的次用户的功率发射等级。
例如，电子设备200位于CxM侧，在发现某一信道上存在非协作干扰时，处理单元201将提取的非协作干扰的特征发送给SAS，SAS在获知产生非协作干扰的次用户为本SAS所服务的或者本SAS管理的另一CxM所服务的次用户后，针对该次用户的频谱使用行为进行调整，例如，调整其频谱或波束或者功率发射等级，在频谱资源充裕的情况下还可以为其分配额外的频谱资源或者为其借调其他SAS的可用频谱资源。
针对这种情况，图5所示的非协作干扰确定之前的信息流程依然适用，图7示出了用于非协作干扰确定和处理的信息流程的示意图。在图7中，受到非协作干扰的CBSD的CxM向SAS发送处理请求，如果产生非协作干扰的CBSD(称为干扰CBSD)为另一CxM所服务的，则SAS经由该CxM对干扰CBSD的频谱使用行为进行调整，比如为其分配额外的频谱资源、调整其波束或降低其功率等级等(即，图7中所示的非协作干扰处理响应)。可以理解，SAS所分配的额外的可用频谱也可以是借调自同区域的其他SAS的可用频谱。另外，如图7中的虚线所示，如果干扰CBSD是由SAS所服务的，则SAS对干扰CBSD的频谱使用行为进行调整。随后，SAS还可以将处理的结果发送给受到非协作干扰的CBSD的CxM。
另一方面，如果产生非协作干扰的次用户为另一SAS(称为第二SAS)服务的次用户，则CxM可以通过SAS向第二SAS发送上述处理请求。第二SAS对造成非协作干扰的次用户的频谱使用行为进行调整，比如为其分配额外的频谱资源、调整其波束或降低其功率等级等。图8示出了这种情况下用于非协作干扰确定和处理的信息流程的示意图。其中，虽然图中未示出，但是第二SAS对干扰CBSD的非协作干扰处理响应也可以是通过CxM进行的。并且，当第二SAS没有充裕的频谱资源时，也可以向同区域的其他SAS借调频谱。
在另一个示例中，电子设备200位于SAS侧，在发现非协作干扰时，处理单元201将处理请求发送给同区域的其他SAS，由服务于造成非协作干扰的次用户的第二SAS对该次用户频谱使用行为进行调整，比如为其分配额外的频谱资源、调整其波束或降低其功率等级等。图9示出了这种情况下用于非协作干扰确定和处理的信息流程的示意图。其中，第二SAS执行的频谱调整与图8中类似，在此不再重复。
根据本实施例的电子设备200能够提取非协作干扰的特征，进而对非协作干扰进行处理，从而优化频谱接入系统的性能，提高频谱利用效率。
<第三实施例>
图10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300的功能模块框图，如图10所示，电子设备300包括：获取单元301，被配置为获取来自共存管理装置的处理请求，该处理请求包括共存管理装置监测的非协作干扰的特征；以及处理单元302，被配置为响应于该处理请求来处理非协作干扰。
其中，获取单元301和处理单元302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300例如可以位于SAS侧或者可通信地连接到SAS。
在一个示例中，获取单元301被配置为根据非协作干扰的特征来确定产生非协作干扰的干扰次用户的信息，并且处理单元302针对该干扰次用户进行调整以处理非协作干扰。
例如，处理单元302可以为干扰次用户分配额外的频谱资源，其中，额外的频谱资源可以为电子设备300所在的频谱管理装置的空闲频谱资源，或者该频谱管理装置从其他频谱管理装置借用的频谱资源。
此外，处理单元302还可以调整干扰次用户的频谱或波束以避免非协作干扰。或者，处理单元302还可以调整干扰次用户的功率发射等级。
在另一个示例中，处理单元302还可以根据频谱资源使用状况，来动态设置非协作干扰所涉及的区域的与频谱使用相关的阈值，以处理非协作干扰。
例如，与频谱使用相关的阈值包括如下中的一个或多个：信号功率与噪声功率比阈值，邻道干扰功率与噪声功率比阈值。其中，邻道干扰功率为在用户工作信道相邻的信道上所遭受到的来自其他无线电设备的干扰信号、带外辐射或杂散辐射的功率。
作为一个示例，当系统可用频道数量少于为避免有害干扰所需的频道数量、即频谱资源并不充裕时，处理单元302可以动态设置与频谱使用相关的阈值，比如降低所涉及区域中基站覆盖区域边界的信号功率与噪声功率比的阈值；反之，当系统可用频道数量多于为避免有害干扰所需的频道数量、即频谱资源充裕时，处理单元302可以提高所涉及区域中基站覆盖区域边界的信号功率与噪声功率比的阈值。这样，可以兼顾系统容量、用户服务质量(QoS)与频谱利用率。
虽然图10中未示出，但是电子设备300还可以包括通信单元，被配 置为执行电子设备300与其他设备的通信功能。例如，获取单元301可以经由通信单元接收处理请求，处理单元302可以经由通信单元将处理结果提供给相关的次用户或共存管理单元。
根据本实施例的电子设备300能够对非协作干扰进行处理，以提高各个用户的通信质量，并提高频谱利用效率。
<第四实施例>
图11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400的功能模块框图，如图11所示，电子设备400包括：监测单元401，被配置为响应于来自管理装置的监测指示，对该监测指示中的包括的信道进行非协作干扰检测；以及提供单元402，被配置为向所述管理装置提供监测报告。
其中，监测单元401和提供单元402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400例如可以位于或者可通信地连接到节点侧，比如CBSD侧。图11中虽然未示出，但是电子设备400也可以包括通信单元，用于进行信息的发送和接收。
电子设备400所在的节点可以用作监测节点，用于对特定的信道进行非协作干扰检测。
在一个示例中，监测单元401还被配置为从管理装置获取通知该电子设备400所在的节点被选择作为监测节点的消息，并且提供单元402向管理装置提供该消息的响应。该响应用于向管理装置指示本节点是否同意作为监测节点工作。管理装置例如可以为CxM或SAS，或者其他频谱管理装置。
提供单元402可以周期性地或在满足预定条件时向管理装置提供监测报告，具体的方式取决于管理装置的设置，该设置例如也可以包括在监测指示中。
例如，监测报告可以包括如下中的一个或多个：所测量的干扰噪声比，时间戳，信道索引。根据该监测报告，管理装置可以进行非协作干扰的确定和处理。
如图11中的虚线框所示，电子设备400还可以包括：存储单元403， 用于存储非协作干扰的历史数据。存储单元403例如可以实现为各种存储器。该历史数据可以为该节点的历史测量结果，并且可以提供给管理装置，以供其选择指定信道之用。
在一个示例中，提供单元402可以被配置为基于历史数据对各个信道进行评分，并将该评分提供给管理装置，其中，当某一信道上出现非协作干扰的频率越高时，该信道的评分越高。具体的评分方式例如可以参见第一实施例所述。在该示例中，由节点对历史测量结果进行处理，并仅将评分的结果提供给管理装置，减小了信令开销。
根据本实施例的电子设备400能够对指定信道进行监测，从而辅助管理装置进行非协作干扰的确定和处理。
<第五实施例>
在上文的实施方式中描述用于无线通信的电子设备的过程中，显然还公开了一些处理或方法。下文中，在不重复上文中已经讨论的一些细节的情况下给出这些方法的概要，但是应当注意，虽然这些方法在描述用于无线通信的电子设备的过程中公开，但是这些方法不一定采用所描述的那些部件或不一定由那些部件执行。例如，用于无线通信的电子设备的实施方式可以部分地或完全地使用硬件和/或固件来实现，而下面讨论的用于无线通信的方法可以完全由计算机可执行的程序来实现，尽管这些方法也可以采用用于无线通信的电子设备的硬件和/或固件。
图12示出了根据本申请的一个实施例的用于无线通信的方法的流程图，该方法包括：从管理区域中的监测节点获取所述监测节点针对指定信道的监测结果(S12)，其中，指定信道为可用频谱资源上的一个或多个信道，并且指定信道是基于节点的历史数据估计的存在非协作干扰的可能性最高的一个或多个信道；以及基于监测结果判断指定信道上是否存在非协作干扰(S13)。该方法例如可以在频谱管理装置侧执行。
在一个示例中，在步骤S12中如下选择指定信道：基于监测节点与该监测节点的至少部分邻居节点对于各个信道的历史使用状况来对信道进行预测评分，例如，当某一信道上出现非协作干扰的概率越高时，该信道的预测评分越高；以及选择预测评分最高的N个信道作为指定信道。其中，N可以为预定指定的正整数以及/或者所选择的信道的预测评分超 过预定评分阈值。
例如，可以如下对信道进行预测评分：基于对各个信道的历史使用状况，获得监测节点与该监测节点的各个邻居节点对于各个信道的历史评分；基于该历史评分计算监测节点与各个邻居节点之间的评分相似度，并选择评分相似度满足预定条件的邻居节点作为所述至少部分邻居节点；以及根据监测节点和所选择的邻居节点的历史评分来对信道进行预测评分。例如，可以通过对监测节点和至少部分邻居节点对于各个信道的历史评分求平均来估计预测评分。其中，邻居节点为位于监测节点的监测范围内的节点。
在步骤S13中可以通过将指定信道上检测到的累积干扰值与预定干扰容限进行比较来判断指定信道上是否存在非协作干扰。例如，可以基于所监测的指定信道的干扰噪声比INR来判断是否存在非协作干扰。具体地，可以通过判断所监测的INR与在不存在非协作干扰的情况下所计算的INR之间的差是否超过预定阈值，来判断指定信道上是否存在非协作干扰。或者，可以通过将所监测的INR与基于节点的历史数据设置的INR阈值相比较，来判断指定信道上是否存在非协作干扰。
此外，如图12中的一个虚线框所示，上述方法还可以包括步骤S11：基于管理区域中的节点的如下参数中的一个或多个来选择作为监测节点的节点：节点的位置、节点的监测能力、节点的负荷因子。
其中，步骤S11还可以包括生成包括指示被选择为监测节点的信息以提供给所选择的监测节点以及获取来自监测节点的响应。步骤S12中还包括从监测节点获取监测结果。
例如，在步骤S11中，可以基于各个节点与关键位置之间的有效距离来选择监测节点，其中，关键位置是管理区域中要进行非协作干扰监测的位置，有效距离基于节点与关键位置之间的物理距离和节点的负荷因子获得。可以选择距各个关键位置的有效距离最小的节点作为针对该关键位置的监测节点。关键位置可以包括如下位置中的一个或多个：主用户的位置、受保护的次用户的位置、不同共用信道组之间的交叠区域。节点的负荷因子例如为节点当前的负荷与节点能够承受的最大负荷之间的比值。步骤S11可以根据节点的负荷的变化来动态执行。
如图12中的另一个虚线框所示，上述方法还可以包括步骤S14：在 监测到非协作干扰的情况下，提取非协作干扰的特征。例如，非协作干扰的特征包括以下中的一个或多个：干扰带宽，干扰噪声比INR，干扰信号类型，非协作干扰出现的时间。
如图12中的另一个虚线框所示，上述方法还可以包括步骤S15：基于所非协作干扰的特征，进行非协作干扰的处理。例如，该处理可以包括以下中的一个或多个操作：调整受到非协作干扰的影响的用户的频谱、波束或功率发射等级；向频谱管理装置请求额外的频谱资源。或者，该处理还可以包括：生成提供给频谱管理装置的处理请求，以请求频谱管理装置进行非协作干扰的处理，处理请求包括非协作干扰的特征；以及从频谱管理装置获取响应于处理请求的处理结果，处理结果可以包括以下中的一个或多个：为产生非协作干扰的次用户分配了额外的频谱资源；调整了产生非协作干扰的次用户的频谱或波束；调整了产生非协作干扰的次用户的功率发射等级。
图13示出了根据本申请的另一个实施例的用于无线通信的方法的流程图，该方法包括：获取来自共存管理装置的处理请求，处理请求包括共存管理装置监测的非协作干扰的特征(S21)；以及响应于该处理请求来处理非协作干扰(S22)。该方法例如可以在频谱管理装置侧执行。
在一个示例中，在步骤S22中，根据非协作干扰的特征来确定产生非协作干扰的干扰次用户的信息，并针对该干扰次用户进行调整以处理非协作干扰。例如，可以为干扰次用户分配额外的频谱资源，其中，额外的频谱资源为电子设备所在的频谱管理装置的空闲频谱资源，或者该频谱管理装置从其他频谱管理装置借用的频谱资源。或者，可以调整干扰次用户的频谱或波束。还可以调整干扰次用户的功率发射等级。
在步骤S22中，还可以动态设置非协作干扰所涉及的区域的与频谱使用相关的阈值，以处理非协作干扰。例如，与频谱使用相关的阈值包括如下中的一个或多个：信号功率与噪声功率比阈值，邻道干扰功率与噪声功率比阈值。
如图13中的虚线框所示，上述方法还可以包括步骤S23：将处理结果提供给相关的次用户或共存管理装置。
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方法的流程图，该方法包括：响应于来自管理装置的监测指示，对该监测指示 中包括的信道进行非协作干扰监测(S31)；以及向管理装置提供监测报告(S32)。该方法例如可以在节点侧、即次用户的设备侧执行。
此外，虽然图14中未示出，但是在步骤S31之前，上述方法还可以包括：从管理装置获取通知该电子设备所在的节点被选择作为监测节点的消息，以及向管理装置提供该消息的响应。在步骤S32之后，上述方法还可以包括：存储非协作干扰的历史数据。
例如，监测报告可以包括如下中的一个或多个：所测量的干扰噪声比，时间戳，信道索引。
上述方法还可以包括：基于历史数据对各个信道进行评分，并将该评分提供给管理装置，其中，当某一信道上出现非协作干扰的频率越高时，该信道的评分越高。
注意，上述各个方法可以结合或单独使用，其细节在第一至第四实施例中已经进行了详细描述，在此不再重复。
以下，为了更好地理解本申请的技术，给出了两个系统仿真示例。应该理解，这些仿真示例仅是说明性的，而非限制性的。
图15示出了用于仿真的系统场景一的示意图。其中，PU代表主用户，并假设存在4个共存次用户，分别为CBSD1至CBSD4，CxM为其分配的频道分别是Ch1～Ch4。选取到受保护的主用户PU的有效距离最近的CBSD1作为监测节点，CBSD2、CBSD3和CBSD4为共存次用户，其信道评分表如图16所示。该信道评分表例如采用第一实施例中参照图3所示的方式获得。
根据该信道评分表(将未给出评分的项看做评分为0)，可以计算监测节点与各用户节点之间的相似度：S(1,2)＝0.82，S(1,3)＝0.81，S(1,4)＝0.64。
假设选取邻居节点的门限值是S 0＝0.8，因此节点CBSD2和CBSD3被选择作为监测节点CBSD1的邻居节点。而节点CBSD4与监测节点CBSD1的相似度小于门限值，因此不被选做邻居节点。
应该注意，在尚没有历史数据的初始状态下，监测节点感知信道上是否存在非协作干扰，需采取轮询式信道感知，即对所有信道进行感知。在经过一段时间后，各监测节点开始工作，从而对信道产生历史评分。 监测节点根据本监测节点及其邻居节点的历史评分，给出当前时刻各信道的预测评分值。图17示出了一个预测评分的示例。
其中，预测评分R(Ch6)＝4.3；R(Ch1)＝1.3；R(Ch5)＝1.3；R(Ch8)＝1。对预测评分值进行从高到低的排序：R(Ch6)>R(Ch1)＝R(Ch5)>R(Ch8)，因此，监测节点首先对信道6进行检测，然后再对信道1、信道5进行检测，最后对信道8进行检测，检测是否存在非协作干扰。
假设监测节点检测一个信道所需的时间为10ms，利用传统的信道感知算法，检测出存在非协作干扰的信道(Ch6)需要60ms；而采用提出的信道推荐算法，只需10ms就可检测出是否存在非协作干扰，显著缩短了检测时延，提高了非协作干扰检测的准确性。
图18示出了用于仿真的系统场景2的示意图。在1000m×1000m的仿真区域中，假设有两个共存管理组CxG1和CxG2，每个CxG有10个CBSD次用户(Secondary User，SU)，假设两个共存组CxG1与CxG2的次用户分别随机均匀布在两个500m×500m区域内。为保障次用户的性能，选取位于两个共存组交界区的位置(500,500)的次用户为监测节点。
在仿真中采用如下仿真参数：工作频率，3.6GHz；信道带宽，20MHz；CBSD的默认发射功率，13dBm；CBSD处的噪声系数(Noise Figure，NF)，10dB；CBSD处的干扰裕量，20dB。
假设CBSD次用户的干扰门限值为-71dBm，CxG1次用户对监测节点所产生的累积干扰低于干扰门限。可以通过仿真监测节点所受到的来自新接入的CxG2次用户(即CxG2所管理的CBSD)的累积干扰来判断是否出现超出干扰门限的非协作干扰。
图19示出了进行共存协作之前的累积干扰，以及采用三种不同协作方案以消除非协作干扰后，监测节点位置处所受累积干扰的比较。通过比较，可以发现采用协作方案后可以有效地避免对共存次用户(即CxG1次用户)的有害干扰。
图20是示出了共存协作前和采用三种不同的协作方案后CBSD发射功率的比较。其中，方案一是不允许超出干扰容限的CxG2的CBSD接入(即图20中所示的发射功率设为“OFF(关)”的三个CBSD立即终止发射)，因此协作后的累积干扰小于等于门限值。方案二与方案三则是 通过对次用户发射功率的调整来抑制干扰的，使得CxG2CBSD产生的累积干扰不超过干扰门限值。方案1简单易行，方案2与方案3考虑到次用户间的公平性，方案2通过尽量仅调整后来次用户的发射功率等级而更倾向于先接入频谱的次用户，方案3通过下调所有次用户的发射功率等级而试图寻求对所有共存次用户的公平性。
