根据本公开的一个实施例，无线电资源管理系统1管理的高优先级系统可以是对频谱资源具有常规使用权的主系统，通常包括主基站和主用户；低优先级系统可以是没有被许可频谱资源的使用权而机会性使用所述频谱资源的次系统，通常包括次基站和次用户。例如，无线电资源管理系统管理1的高优先级系统例如可以是陆地电视广播系统、雷达系统，低优先级系统例如可以是ETSI组织提出的资源可重配置系统(RRS)，比如利用电视或雷达频段的WiFi通信系统；又例如高优先级系统是WiFi通信系统，而低优先级系统是3GPP的LTE演进标准中提出的采用授权辅助接入(Licensed Assisted Access，LAA)技术的蜂窝移动通讯系统，从而利用WiFi频段资源。
根据本公开的另一个实施例，高优先级系统也可以是在保障主系统的频谱使用下、机会性使用频谱资源的高优先级次系统；低优先级系统可以 是对于该频谱资源的使用具有比高优先级系统低的优先级的次系统。例如，高优先级系统可以是例如应用于医院、急救中心等场景下的无线电通信系统，低优先级系统可以是应用于普通场景下的无线电通信系统。
根据本公开的实施例，高优先级次系统和低优先级次系统可以包括例如次用户和次基站，也可以仅包括次用户(例如，没有设置次基站，而由无线电资源管理系统直接管理的次用户的情况)，因此，在本公开的描述中，将次用户泛指为次系统以涵盖上述情况。
更具体地，根据本公开的高优先级次系统和低优先级次系统的具体实现形式例如可以是移动终端(诸如智能电话、平板个人计算机(PC)、笔记本式PC、便携式游戏终端、便携式/加密狗型移动路由器和数字摄像装置)或者车载终端(诸如汽车导航设备)，也可以是执行机器对机器(M2M)通信的终端(也称为机器类型通信(MTC)终端)，或者是执行设备到设备(D2D)通信的终端。
根据本公开，为低优先级系统分配频谱资源供其使用的基本原则是需要首先确保低优先级系统对于频谱资源的使用不会干扰高优先级系统的频谱资源使用。
根据本公开，无线电资源管理系统1可以是用于管理特定范围内的通信系统(包括高优先级系统和低优先级系统)的信息的例如RRS中的地理位置信息数据库(GLDB)，也可以是覆盖特定范围内的通信系统的先进的定位引擎(AGE)，还可以是例如eNodeB或是例如C-RAN架构下的基带云等网络侧设备。此外，无线电资源管理系统1可以是独立于高优先级系统和低优先级系统的一个单独的实体，也可以是分布在各个高优先级系统和低优先级系统上的多个实体的组合。
根据本公开的无线电资源管理系统1用于对其管理范围内的低优先级系统进行管理，以使得低优先级系统在对高优先级系统的干扰符合预定条件的前提下机会性地利用频谱资源，例如主系统的授权频谱资源。
根据本公开，机会性地利用频谱资源是指在不影响主系统或者主系统和高优先级次系统的频谱资源使用的情况下(包括对主系统的频谱资源使用的干扰在主系统容许的范围内)，使得高优先级次系统和低优先级次系统两者或者低优先级系统使用频谱资源；如果高优先级次系统和低优先级次系统两者或者低优先级系统对频谱资源的使用对主系统产生的影响在主系统的允许范围之外，则禁止高优先级次系统和低优先级次系统两者或 者低优先级系统使用频谱资源。
图2是示意性地示出根据本公开的无线电资源管理系统的另一示例性结构框图。
如图2所示，除了与图1的无线电资源管理设备1类似地包括获取装置10、选择装置20和参数确定装置30之外，无线电资源管理设备2还包括：存储装置40，用于存储所述至少一个高优先级系统和至少一个低优先级系统的地理位置信息，其中，所述获取装置10还配置为访问所述存储装置40以获取所述至少一个次系统和所述至少一个主系统的地理位置信息。
通常，可以将主系统的位置信息和服务边界信息存储在无线电资源管理系统的存储装置40中，而例如GPS(全球定位系统)的定位装置可以向次系统上报位置信息和定位参数(定位误差)，从而无线电资源管理系统可以从各个次系统获取其位置信息和定位参数并存储在存储装置40中。然而由于例如GPS等的定位装置的定位存在不确定性(例如定位装置的定位存在误差)和/或次系统由于移动而产生位置变化，因此通常需要基于定位装置上报的次系统的位置确定一定的位置范围作为包括高优先级次系统和低优先级次系统可能出现的位置的集合。在本公开的以下描述中，将高优先级次系统可能出现的位置的范围称为该高优先级次系统(或高优先级系统)的待保护范围，将低优先级系统可能出现的位置范围称为该低优先级系统的定位范围。此外，主系统具有一定的服务区域，对于主系统的干扰通常是指对主系统服务区域的干扰，在下文中将该区域称为主系统(或高优先级系统)的待保护范围。
获取装置10可以基于高优先级系统和低优先级系统中每一个的位置信息，获取该高优先级系统的待保护范围以及低优先级系统的定位范围。例如，获取装置可以从各个次系统获取定位装置上报的位置信息以及定位装置的定位参数(例如定位误差)，从而获取以定位装置上报的位置为中心点、半径为该定位参数(例如50米)的圆形范围作为该高优先级系统和低优先级系统可能出现的位置集合，即高优先级系统的待保护范围和低优先级系统的定位范围。
针对无线电资源管理系统1管理的至少一个高优先级系统中的每一个，选择装置20可以基于获取装置获取的该高优先级系统的待保护范围，为每个低优先级系统在其定位范围内选择对该高优先级系统产生的干扰 满足预定条件的位置作为该低优先级系统的参考位置。
由于要保护的高优先级系统不能受到低优先级系统的干扰，因此为低优先级系统确定其频谱使用的工作参数时必须考虑：使得在低优先级系统的定位范围内该低优先级系统的所有可能出现位置对要保护的高优先级系统都不会产生干扰(或者产生的干扰在该高优先级系统的干扰阈值范围之内)。根据本公开，为了减少计算量，例如，选择装置20可以在低优先级系统的定位范围内选择对于该高优先级系统产生的干扰为最大的至少一个位置作为该低优先级系统的参考位置，即作为该低优先级系统的位置以计算该低优先级系统使用频谱资源时的工作参数。
根据本公开的优选实施例，选择装置20可以被配置为针对每个高优先级系统，基于各个低优先级系统与该高优先级系统之间的距离、路径损耗、以及与所述高优先级系统和所述低优先级系统所处环境有关的环境因素至少其中之一来确定每个低优先级系统的参考位置。
例如，低优先级系统的定位范围内、与高优先级系统之间具有最小路径损耗的位置可以被认为是对该高优先级系统产生最大干扰的位置。因此，选择装置20可以在低优先级系统的定位范围内选择与该高优先级系统之间路径损耗最小的位置作为该低优先级系统的参考位置。又例如，在低优先级系统的定位范围内，与该高优先级系统之间距离最小的位置通常被认为是对该高优先级系统产生最大干扰的位置，因此，选择装置20例如可以在低优先级系统的定位范围内选择与该高优先级系统之间距离最小的位置作为该低优先级系统的参考位置。
此外，选择装置20还可以基于至少一个高优先级系统以及至少一个低优先级系统所处的环境，确定每个低优先级系统的参考位置。至少一个高优先级系统以及至少一个低优先级系统所处的环境例如包括应用场景、地形地貌等环境因素。
图3是示意性地示出如图1所示的选择装置的一种可能的示例结构的框图。
如图3所示，选择装置20包括：判定单元201，用于针对每个高优先级系统，判断各个低优先级系统的定位范围与该高优先级系统的待保护范围之间是否有障碍物；以及选择单元202，用于基于各个低优先级系统的定位范围与该高优先级系统的待保护范围之间是否有障碍物以及是否有交叠，来选择所述低优先级系统的参考位置。
根据本公开，可以通过获取装置10从例如地理位置信息系统(GIS)中获取至少一个高优先级系统和至少一个低优先级系统的环境信息。地理位置信息系统可以位于无线电资源管理系统1内，或者也可以是独立于无线电资源管理系统1的单个装置。判断单元201可以根据获取装置获取的环境信息，针对每个高优先级系统，判断各个低优先级系统的定位范围与该高优先级系统的待保护范围之间是否有阻碍视距的障碍物(在本文中，障碍物并非指位于高低优先级系统之间的所有物体，而是指阻碍视距的物体，例如建筑物)。例如，判断单元可以基于低优先级系统的天线与高优先级系统的天线之间(例如低优先级系统基站的天线与高优先级系统基站的天线之间)是否有视通来判断低优先级系统的定位范围与高优先级系统的待保护范围之间是否有障碍物。
根据本公开，判断单元201可以基于高优先级系统和低优先级系统的天线高度与建筑物之间的高度，确定该低优先级系统的定位范围与高优先级系统的待保护范围之间是否有障碍物。例如判断单元201可以基于高优先级系统的天线顶点和低优先级系统的天线顶点之间的连线与位于高低优先级系统之间的物体之间的间隙是否跨过例如菲尼尔区来判断，该物体是否构成低优先级系统的定位范围与高优先级系统的待保护范围之间是否有障碍物。
选择单元202根据低优先级系统的定位范围与高优先级系统的待保护范围之间的障碍物和交叠情况，在低优先级系统的定位范围内选择低优先级系统的参考位置。
具体地，选择单元202针对每个高优先级系统，基于如下方式之一为每个低优先级系统选择参考位置：
(i)当所述低优先级系统的定位范围与所述高优先级系统的待保护范围之间无障碍物且无交叠或者当所述低优先级系统的定位范围与所述高优先级系统的待保护范围之间完全被障碍物遮挡时，选择该低优先级系统的定位范围边界上距离所述高优先级系统的待保护范围的边界最近的位置作为该低优先级系统的参考位置；
(ii)当所述低优先级系统的定位范围与所述高优先级系统的待保护范围之间有部分被障碍物遮挡且无交叠时，在该低优先级系统的定位范围中选择与所述高优先级系统的待保护范围内的任意点可以视通且距离最近的位置作为该低优先级系统的参考位置；
(iii)当所述低优先级系统的定位范围与所述高优先级系统的待保护范围之间有部分被障碍物遮挡且有交叠时，如果遮挡部分能够完全覆盖交叠部分，则在该低优先级系统的定位范围中选择与所述高优先级系统的待保护范围内的任意位置可以视通且距离最近的位置作为该低优先级系统的参考位置；
(iv)当所述低优先级系统的定位范围与所述高优先级系统的待保护范围之间无障碍物且有交叠时或者有部分被障碍物遮挡且有交叠并且遮挡部分不能够完全覆盖交叠部分时，将该低优先级系统的参考位置确定为与该高优先级系统的位置重叠。
下面结合图4(a)和图4(b)详细描述选择单元202在各种应用场景下为低优先级系统选择参考位置的处理。
更具体地，在针对每个高优先级系统、为每个低优先级系统选择参考位置时，如果判断单元201基于获取装置10获取的高优先级系统和低优先级系统的环境信息，判断出该低优先级系统的定位范围与所述高优先级系统的待保护范围之间无障碍物且无交叠(如图4(a)中的场景a所示)，则选择单元202可以在低优先级系统的定位范围内选择其边界上距离高优先级系统的待保护范围的边界最近的位置作为该低优先级系统的参考位置。本公开不限于此，根据本公开的另一实施例，选择单元202也可以在低优先级系统的定位范围内选择与高优先级系统之间的路径损耗最小的点作为该低优先级系统的参考位置。
当判断单元201基于获取装置10获取的高优先级系统和低优先级系统的环境信息，判断出该低优先级系统的定位范围与所述高优先级系统的待保护范围之间无障碍物且有交叠(如图4(a)中的场景b所示)时，这通常表明低优先级系统的位置与该高优先级系统的位置重叠的可能性很高，因此选择单元202可以将该低优先级系统的参考位置确定为与该高优先级系统的位置重叠。
当判断单元201基于获取装置10获取的高优先级系统和低优先级系统的环境信息，判断出该低优先级系统的定位范围与所述高优先级系统的待保护范围之间有部分遮挡且无交叠(如图4(a)中的场景c所示)时，选择单元202可以在低优先级系统的定位范围内选择与所述高优先级系统的待保护范围内的任意位置可以视通且距离最近的位置作为该低优先级系统的参考位置。本公开不限于此，根据本公开的另一实施例，选择单 元202也可以在低优先级系统的定位范围内选择与高优先级系统的待保护范围内的任意位置可以视通且路径损耗最小的点作为该低优先级系统的参考位置。
根据本公开，判断单元201可以基于高优先级系统和低优先级系统的天线高度，确定该低优先级系统的定位范围中的各个位置与高优先级系统的待保护范围内的任意位置是否视通(Line-of-Sight(LOS))，即高优先级的天线顶点与低优先级的天线顶点之间是否有遮挡。
当判断单元201基于获取装置10获取的高优先级系统和低优先级系统的环境信息，判断出该低优先级系统的定位范围与所述高优先级系统的待保护范围之间有部分遮挡且有交叠时：
(1)如果遮挡部分能够完全覆盖交叠部分(如图4(b)中的场景d(1)所示)，则与图4(a)中的场景c类似，选择单元202可以在低优先级系统的定位范围内选择与所述高优先级系统的待保护范围内的任意位置可以视通且距离最近的位置作为该低优先级系统的参考位置。与图4(a)中的场景c类似，根据本公开的另一实施例，选择单元202也可以在低优先级系统的定位范围内选择与高优先级系统的待保护范围内的任意位置可以视通且路径损耗最小的点作为该低优先级系统的参考位置；
(2)如果遮挡部分不能够完全覆盖交叠部分(如图4(b)中的场景d(2)所示)，则表明低优先级系统的位置与该高优先级系统的位置重叠的可能性很高(与图4(a)中的场景b类似)，因此选择单元202可以将该低优先级系统的参考位置确定为与该高优先级系统的位置重叠，从而参数调整装置30可以基于此将该低优先级系统的发射功率确定为0，即将该低优先级系统确定为禁止发射。
当判断单元201基于获取装置10获取的高优先级系统和低优先级系统的环境信息，判断出该低优先级系统的定位范围与所述高优先级系统的待保护范围之间完全被障碍物遮挡(如图4(b)中的场景e所示)，则与图4(a)中的场景a类似，选择单元202可以在低优先级系统的定位范围内选择其边界上距离所述高优先级系统的待保护范围的边界最近的位置作为该低优先级系统的参考位置。与图4(a)中的场景a类似，根据本公开的另一实施例，选择单元202也可以在低优先级系统的定位范围内选择与高优先级系统之间的路径损耗最小的点作为该低优先级系统的参考位置。
参数确定装置30基于每个低优先级系统的参考位置，为该高优先级系统确定所述低优先级系统的工作参数。
根据本公开，参数确定装置30确定的低优先级系统的工作参数可以是该低优先级系统的最大发射功率、工作频道等等。
根据本公开的一个实施例，在选择单元202将该低优先级系统的参考位置确定为与该高优先级系统的位置重叠的情况下，参数调整装置30可以将该低优先级系统的发射功率确定为0，即将该低优先级系统确定为禁止发射。但是本公开不限于此，本领域技术人员可以理解，当无线电资源管理系统1能够获取或感知高优先级系统的关于频谱使用时段的信息时，也可以将该低优先级系统设置为在高优先级系统不使用频谱资源时使用频谱资源。
根据本公开的实施例，参数确定装置30被配置为针对至少一个高优先级系统中的每个高优先级系统，基于每个低优先级系统的参考位置确定每个低优先级系统的工作参数，并在针对至少一个高优先级系统为每个低优先级系统确定的至少一个工作参数中选择最低的发射功率作为该低优先级系统的发射功率。
具体地，针对无线电资源管理系统1管理的高优先级系统有两个或两个以上的情况，参数确定装置30可以针对每个高优先级系统为各个低优先级系统确定工作参数，从而为每个低优先级系统确定了一组工作参数(该组工作参数中的每个工作参数对应于一个高优先级系统，例如在无线电资源管理系统管理的高优先级系统为2个时，每个低优先级系统的工作参数组中包括两个工作参数)。参数确定装置30例如可以在针对每个低优先级系统所确定的一组工作参数中，选择对各个高优先级系统产生的干扰最小的工作参数作为该低优先级系统的工作参数，从而使得每个低优先级系统在以该工作参数使用频谱资源时不会对各个高优先级系统产生干扰(或者产生的干扰在高优先级系统的容忍范围之内)。
参数确定装置30例如可以根据低优先级系统的参考位置计算所有低优先级系统对于该高优先级系统的聚合干扰，从而基于聚合干扰，确定各个低优先级系统为确保对高优先级系统的干扰在其容忍范围之内而可以使用的工作参数。
根据本公开的一个实施例，对于高优先级系统为对所述频谱资源具有常规使用权的主系统、低优先级系统为机会性使用所述频谱资源的次系统 的情况，参数确定装置可以基于次系统的参考位置，确定主系统受到的聚合干扰，并根据该聚合干扰与主系统的干扰阈值(即主系统能够容忍的最大干扰)之差，确定各个低优先级系统的工作参数。
根据本公开的另一个实施例，对于高优先级系统为机会性使用主系统的频谱资源的高优先级次系统、低优先级系统为机会性使用主系统的频谱资源且对于频谱资源的使用具有比所述高优先级次系统低的优先级的低优先级次系统的情况，参数确定装置30可以基于高优先级系统在其待保护范围内的各个位置受到的聚合干扰的情况，确定高优先级系统的干扰位置，从而基于该干扰位置确定低优先级系统的工作参数。
图5是示意性地示出如图1所示的参数确定装置的一种可能的示例结构的框图。
如图5所示，参数确定装置30包括：聚合干扰计算单元301，用于针对每个高优先级次系统，基于选择单元202确定的各个低优先级次系统的参考位置，计算该高优先级次系统的待保护范围内各个位置受到的聚合干扰；以及干扰位置确定单元302，用于根据所述聚合干扰计算单元301计算的聚合干扰，在所述高优先级次系统的待保护范围内选择所述高优先级次系统的干扰位置，以便基于所述高优先级次系统的干扰位置确定对所述各个低优先级次系统的工作参数调整。
根据本公开，聚合干扰计算单元301基于选择单元202为每个低优先级次系统确定的参考位置，计算在高优先级次系统的待保护范围内的各个位置受到的聚合干扰。针对高优先级系统的待保护范围内选取的每个位置(例如在以该高优先级次系统的GPS定位位置为中心、以例如50m的预定值为半径的待保护范围内，可以将该待保护范围切分为10m×10m的矩形区域内并以网格交点处的位置作为高优先级次系统待保护范围内选取的各个位置)，基于各个低优先级系统的位置计算高优先级系统在该位置受到的聚合干扰的计算方法是本领域公知的，在此不做详细描述。
根据本公开，干扰位置确定单元302可以根据聚合干扰计算单元301计算的聚合干扰，在所述高优先级次系统的待保护范围内选择具有最大聚合干扰的位置作为所述高优先级系统的干扰位置，从而使得各个低优先级系统在基于该干扰位置而确定的工作参数下工作时，对(处于包括其所有潜在位置的待保护范围内的)该高优先级次系统的干扰影响均在该高优先级系统的允许范围之内。
如图6所示，在为低优先级系统A7、A8、和A9确定了参考位置a8、a9和a10之后，针对高优先级系统B的待保护范围内的各个位置(包括b1、b2、b3和b4)计算了低优先级系统A1、A2和A3对其的聚合干扰，当高优先级系统B的待保护范围内的位置b1受到的聚合干扰最大时，可以将该位置b1确定为高优先级系统B的干扰位置。
在干扰位置确定单元302为高优先级次系统确定了干扰位置之后，参数确定装置30可以基于该干扰位置(例如对于图6中的高优先级系统B确定的干扰位置b1)，为低优先级系统确定工作参数。
根据本公开的一个实施例，参数调整装置30可以针对所有的低优先级系统统一调节预定参数值(例如将所有低优先级系统的当前发射功率都减小第一预定参数值△1作为低优先级系统的新发射功率)，预定参数值例如可以基于高优先级系统在干扰位置受到的聚合干扰与高优先级系统的干扰阈值(即高优先级系统能够容忍的最大干扰值)之差D以及要调整的低优先级系统的数量N来确定(即△1＝D/N1)。
根据本公开的另一实施例，参数调整装置30可以根据低优先级次系统的参考位置，确定各个低优先级次系统的调节量。例如，可以首先确定其参考位置与高优先级次系统的干扰位置之间的距离在预定值范围内的低优先级系统，针对这些低优先级次系统调节预定参数值△2(△2可以根据高优先级次系统在干扰位置受到的聚合干扰与高优先级次系统的干扰阈值之差D以及要调整的低优先级次系统的数量△2＝D/N2)。当然，本领域技术人员可以理解，如果将与高优先级次系统之间的距离在预定范围内的所有低优先级次系统的发射功率都设置为0也不足以使得高优先级次系统受到的干扰在其干扰阈值以下时，则可以进一步调节除上述低优先级次系统之外的其他低优先级次系统的发射功率。
虽然以上针对高优先级系统为高优先级次系统、低优先级系统为低优先级次系统的情况描述对于低优先级系统确定工作参数的处理，本领域技术人员可以理解，也可以对于高优先级系统为主系统、低优先级系统为次系统的情况类似地进行处理，以确定对于作为低优先级系统的各个次系统的工作参数，使得低优先级系统以该工作参数工作时，不会对主系统的频谱使用造成影响。
根据本公开的另一实施例，高优先级系统可以包括主系统和高优先级次系统两者，低优先级系统可以是低优先级次系统。在此情况下，参数确 定装置30被配置为基于每个低优先级次系统的参考位置，确定所述低优先级次系统的工作参数，以使所述低优先级系统对频谱资源的使用满足所述主系统和所述高优先级次系统两者的干扰要求。
例如，参数确定装置30可以依次针对主系统和各个高优先级次系统，基于每个低优先级系统的参考位置确定其发射功率，并且选择例如符合主系统和所有高优先级次系统的干扰要求的发射功率作为该低优先级系统的发射功率，例如参数确定装置30可以在针对主系统和各个高优先级次系统确定的、低优先级系统的一组发射功率中选择最小的发射功率作为该低优先级系统的发射功率。
在某些场景下，无线电资源管理设备1管理的高优先级系统不仅受到该无线电资源管理设备1管理的低优先级系统的干扰，还受到相邻的无线电资源管理系统管理的低优先级系统的干扰。在此情况下，为保障高优先级系统的频谱使用，还应考虑相邻无线电资源管理系统管理的低优先级系统。
图7示出了根据本公开实施例的无线电资源管理系统的另一种示例性结构的框图。
如图7所示，除了与图1的无线电资源管理设备1类似地包括获取装置10、选择装置20和参数确定装置30之外，无线电资源管理系统3还包括通信装置50，用于从相邻无线电资源管理系统接收该相邻无线电资源管理系统所管理的相邻低优先级系统的位置信息，并且向无线电资源管理系统管理的低优先级系统以及所述相邻无线电资源管理系统发送确定的工作参数。
无线电资源管理系统3可以将通过通信装置50接收的、由相邻无线电资源管理系统管理的相邻低优先级系统的位置信息存储在存储装置(例如图2所示的存储装置40)中。
无线电资源管理系统3的获取装置10可以从存储装置获取相邻低优先级系统的位置信息及其定位范围，从而选择装置20可以针对无线电资源管理设备3管理的每个高优先级系统，为该每个相邻低优先级系统在其定位范围内选择参考位置，并由参数确定装置30基于包括无线电资源管理系统3管理的各个低优先级次系统以及相邻无线电资源管理系统管理的各个相邻低优先级系统的参考位置，确定所述低优先级系统的工作参数。选择装置为相邻低优先级系统选择参考位置的处理以及参数确定装置 为包括相邻低优先级系统的低优先级系统确定工作参数的处理例如与参照图1-6描述的选择装置20和参数确定装置30的处理类似，在此不再赘述。
图8示出了根据本公开实施例的无线电资源管理系统的又一种示例性结构的框图。
如图8所示，除了与图1的无线电资源管理设备1类似地包括获取装置10、选择装置20和参数确定装置30之外，无线电资源管理系统4还包括聚合装置60，被配置为将无线电资源管理系统管理的地理位置彼此靠近的至少两个高优先级次系统聚合为一个高优先级次系统，将无线电资源管理系统管理的地理位置彼此靠近的至少两个低优先级次系统聚合为一个低优先级次系统，并且将所述至少两个高优先级次系统的待保护范围的叠加作为该聚合后的高优先级次系统(以下，将聚合后的高优先级次系统称为等效高优先级次系统)的待保护范围，将所述至少两个低优先级次系统的定位范围的叠加作为该聚合后的低优先级次系统(以下，将聚合后的高优先级次系统称为等效高优先级次系统)的定位范围。
图9示出了将多个低优先级次系统聚合以及多个高优先级次系统分别聚合在一起的示例。
如图9所示，多个高优先级次系统X1、X2、X3、X4、X5地理位置彼此靠近，多个低优先级次系统Y1、Y2、Y3、Y4、Y5、Y6、Y7地理位置彼此靠近，因此可以通过聚合装置60将这些高优先级次系统聚合为一个等效高优先级次系统，并将这些低优先级次系统聚合为一个等效低优先级次系统，将这些高优先级次系统的待保护范围的叠加(即这些待保护范围的外延)作为该等效后的高优先级次系统的待保护范围，将这些低优先级次系统的定位范围的叠加(即这些定位范围的外延)作为该聚合后的低优先级次系统的定位范围。
虽然图9示出的是将多个高优先级次系统聚合为一个等效高优先级次系统，将多个低优先级级次系统聚合为一个等效低优先级次系统的情况，但是本公开不限于此，本领域技术人员可以理解，可以根据高/低优先级系统的地理位置将高/低优先级次系统聚合为多个等效高/低优先级系统，例如，当两个高/低优先级次系统的地理位置不足够靠近时，例如两者之间的距离大于某个阈值时，则可以将这两个高/低优先级系统分别聚合到不同的等效高/低优先级系统中。
通过聚合装置60对多个高优先级次系统和低优先级次系统的聚合获得了至少一个等效高优先级次系统及其待保护范围和至少一个等效低优先级次系统及其定位范围，从而选择装置20可以针对每个等效高优先级系统，为包括等效低优先级系统的每个低优先级系统在其定位范围内选择参考位置；以及参数确定装置30可以基于包括等效低优先级系统的每个低优先级系统的参考位置，为该等效高优先级系统确定等效低优先级系统的工作参数，以基于该等效低优先级次系统的工作参数确定聚合为该等效低优先级次系统的各个低优先级次系统的工作参数。根据本公开，例如可以将确定的等效低优先级次系统的发射功率PE平均分配给聚合为该等效低优先级次系统的各个低优先级次系统，即每个低优先级次系统的发射功率PI可以被设置为等于PI＝PE/N，其中N为聚合为该等效低优先级次系统的低优先级次系统的数量。当然，本公开不限于此，也可以根据各个低优先级次系统的发射功率对于等效低优先级次系统的发射功率的贡献比例，对该各个等效低优先级次系统的发射功率进行分配。
此外，虽然以上描述的是将多个高优先级次系统和多个低优先级次系统都进行聚合的示例，但是本公开不限于此，本领域技术人员可以理解，在高优先级系统是主系统，低优先级系统是次系统的情况下，也可以仅对地理位置彼此靠近的多个低优先级系统进行聚合。
虽然以上参照图2、图7、图8描述了在图1的无线电资源管理系统中分别还包括且存储装置、通信装置和聚合装置的示例，但是根据本公开的存储装置40、通信装置50和聚合装置60中的两个或者全部也可以任意组合而包括在图1示出的无线电资源管理系统中。例如，根据本公开的无线电资源管理设备中可以包括获取装置10、选择装置20、参数确定装置30、存储装置40和聚合装置50。
下面描述在考虑相邻无线电管理系统管理的低优先级系统对由无线电资源管理系统1管理的高优先级系统造成干扰的情况下、相邻的无线电资源管理系统的配置。
图10为示出根据本公开另一实施例的无线电资源管理系统的示例性结构框图。
如图10所示，无线电资源管理系统5包括：通信装置70，用于将其所管理的低优先级系统的位置信息发送给相邻无线电资源管理系统以及从相邻无线电资源管理系统接收用于所述无线电资源管理系统管理的低 优先级系统的工作参数，以及参数配置装置80，用于将所述无线电资源管理系统所管理的相应的低优先级系统的当前工作参数配置为所述工作参数，其中，所述相邻无线电资源管理系统基于接收到的所述无线电资源管理系统管理的低优先级系统的位置信息，针对所述相邻无线电资源管理系统管理的每个高优先级系统，为每个低优先级系统在其不确定范围内选择参考位置，并基于每个低优先级系统的参考位置确定对低优先级系统的工作参数的调整，以使所述低优先级系统对频谱资源的使用满足所述高优先级系统的干扰要求。
根据本公开的实施例的相邻无线电资源管理系统可以是如图1-9所描述的无线电资源管理系统1-4。

根据本公开的一个实施例，还提供一种无线电资源管理方法。下面结合图12来描述无线电资源管理方法的一种示例性处理。
如图12所示，根据本公开的实施例的无线电资源管理方法中，处 理流程1200开始于S1210，然后执行S1220的处理。

在步骤S1330中，针对所述至少一个高优先级系统中的每个高优先级系统，基于所述高优先级系统的待保护范围，为每个低优先级系统在其定位范围内选择对所述高优先级系统产生的干扰满足预定条件的位置作为该低优先级系统的参考位置。S1230也可以参考例如结合图1-9描述的选择装置20的操作，在此省略其详细描述。然后执行步骤S1240。
在步骤S1240中，基于每个低优先级系统的参考位置，为所述高优先级系统确定所述低优先级系统的工作参数。S1230也可以参考例如结合图1-9描述的参数确定装置30的操作，在此省略其详细描述。然后执行步骤S1250。
处理流程1200结束于S1250。
根据本公开，在步骤S1230中，可以针对每个高优先级系统，基于各个低优先级系统与该高优先级系统之间的距离、路径损耗、以及与所述无线电资源管理系统所处环境有关的环境因素至少其中之一来确定每个低优先级系统的参考位置。
根据本公开的实施例，步骤S1230可以包括：针对每个高优先级系统，判断各个低优先级系统的定位范围与该高优先级系统的待保护范围之间是否有障碍物；以及基于各个低优先级系统的定位范围与该高优先级系统的待保护范围之间是否有障碍物以及是否有交叠，来选择所述低优先级系统的参考位置。
更具体地，可以针对每个高优先级系统，基于如下方式之一为每个低优先级系统选择参考位置：
(i)当所述低优先级系统的定位范围与所述高优先级系统的待保护范围之间无障碍物且无交叠或者当所述低优先级系统的定位范围与所述高优先级系统的待保护范围之间完全被障碍物遮挡时，选择该低优先级系 统的定位范围边界上距离所述高优先级系统的待保护范围的边界最近的位置作为该低优先级系统的参考位置；
(ii)当所述低优先级系统的定位范围与所述高优先级系统的待保护范围之间有部分被障碍物遮挡且无交叠时，在该低优先级系统的定位范围中选择与所述高优先级系统的待保护范围内的任意点能够视通且距离最近的位置作为该低优先级系统的参考位置；
(iii)当所述低优先级系统的定位范围与所述高优先级系统的待保护范围之间有部分被障碍物遮挡且有交叠时，如果遮挡部分能够完全覆盖交叠部分，则在该低优先级系统的定位范围中选择与所述高优先级系统的待保护范围内的任意位置能够视通且距离最近的位置作为该低优先级系统的参考位置；
(iv)当所述低优先级系统的定位范围与所述高优先级系统的待保护范围之间无障碍物且有交叠时或者有部分被障碍物遮挡且有交叠并且遮挡部分不能够完全覆盖交叠部分时，将该低优先级系统的参考位置确定为与该高优先级系统的位置重叠。
根据本公开的优选实施例，在步骤S1230中，在将该低优先级系统的参考位置确定为与该高优先级系统的位置重叠的情况下，将所述低优先级系统的发射功率确定为0。
根据本公开，在步骤S1230中，可以根据所述高优先级系统和所述低优先级系统的天线高度，确定该低优先级系统的定位范围中的各个位置与所述高优先级系统的待保护范围内的任意位置是否视通。
根据本公开，在步骤S1240中，可以基于每个低优先级系统的参考位置计算所述高优先级系统受到的聚合干扰，并基于所述聚合干扰确定所述低优先级系统的工作参数。
根据本公开的实施例，所述高优先级系统为机会性使用所述频谱资源的高优先级次系统，所述低优先级系统为对于频谱资源的使用具有比所述高优先级次系统低的优先级的低优先级次系统。在此情况下，步骤S1240包括：针对每个高优先级系统，基于确定的各个低优先级系统的参考位置，计算该高优先级系统的待保护范围内各个位置受到的聚合干扰；以及根据所述聚合干扰，在所述高优先级系统的待保护范围内选择所述高优先级系统的干扰位置，以便基于所述高优先级系统的干扰位置确定对所述各个低优先级系统的工作参数。根据本公开的优选实施例，可以选择高 优先级系统的待保护范围内具有最大聚合干扰的位置作为所述高优先级系统的干扰位置。
根据本公开的另一个实施例，高优先级系统为对所述频谱资源具有常规使用权的主系统，所述低优先级系统为机会性使用所述频谱资源的次系统。
根据本公开的又一个实施例，所述高优先级系统为主系统和高优先级次系统，所述低优先级系统为低优先级次系统，所述参数确定装置被配置为基于每个低优先级次系统的参考位置，确定所述低优先级次系统的工作参数，以使所述低优先级系统对频谱资源的使用满足所述主系统和所述高优先级次系统的干扰要求。
根据本公开，步骤S1240还包括：针对至少一个高优先级系统中的每个高优先级系统，基于每个低优先级系统的参考位置确定每个低优先级系统的工作参数，并在针对至少一个高优先级系统为每个低优先级系统确定的至少一个工作参数中选择最低的发射功率作为该低优先级系统的发射功率。
根据本公开的无线电资源管理方法还包括：聚合步骤，用于将无线电资源管理系统管理的地理位置彼此靠近的至少两个高优先级次系统聚合为一个高优先级次系统，将无线电资源管理系统管理的地理位置彼此靠近的至少两个低优先级次系统聚合为一个低优先级次系统，并且将所述至少两个高优先级次系统的待保护范围的叠加作为该等效后的高优先级次系统的待保护范围，将所述至少两个低优先级次系统的定位范围的叠加作为该聚合后的低优先级次系统的定位范围。从而进一步降低确定低优先级系统工作参数时的计算量。
根据本公开的一个实施例，还提供一种电子装置，包括处理电路或一个/多个处理器，该处理电路/处理器被配置为：基于所述无线电资源管理系统管理的至少一个高优先级系统的位置信息以及至少一个低优先级系统的位置信息，获取所述至少一个高优先级系统的待保护范围以及获取所述至少一个低优先级系统的定位范围，其中，所述高优先级系统对于频谱资源的使用具有比所述低优先级系统高的优先级，所述低优先级系统机会性地利用所述频谱资源；针对所述至少一个高优先级系统中的每个高优先级系统，基于所述高优先级系统的待保护范围，为每个低优先级系统在其定位范围内选择对所述高优先级系统产生的干扰满足预定条件的位置 作为该低优先级系统的参考位置；以及基于每个低优先级系统的参考位置，为所述高优先级系统确定所述低优先级系统的工作参数。
根据本公开的无线电资源管理系统和无线电资源管理方法以及电子装置至少具有以下有益效果：能够大大降低为每个低优先级系统确定工作参数时的计算量。具体地，在传统的频谱共享无线电算法中，需要基于每个高优先级系统的待保护范围内的各个位置以及每个低优先级系统的定位范围内的每个位置(通常定位范围越大，用于计算的各个位置的数量越多)确定每个低优先级系统的工作参数，而根据本公开的无线电管理系统和无线电管理方法中，仅需基于每个低优先级级的参考位置(即，定位范围内的一个或有限几个位置)定每个低优先级系统的工作参数，因此，根据本公开，能够大大降低计算量，从而提高无线电资源管理执行确定工作参数操作时的运行效率。
