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、最高发射功率等)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服务的时候，已有的基站以及其所提供的服务具有频谱使用优先权。主系统由主用户基站和主用户组成。次系统由次用户基站和次用户组成，具体来说，次用户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所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。
因此，需要设计在满足主系统对干扰的要求的情况下为次系统适当地分配通信资源的方法。
发明内容
为此，本发明提出了一种管理对参考点产生干扰的多个系统的设备，包括一个或多个处理器，所述处理器被配置为：获取由另一设备确定的允许所述多个系统在所述参考点处产生的干扰总量；基于所获取的干扰总量，为所述多个系统中的每一个系统确定通信资源，以使得所述多个系统在利用所述通信资源进行通信时在所述参考点处产生的干扰彼此不同，并且所述多个系统产生的干扰之和不超过所述干扰总量；以及将为每一个系统确定的通信资源通知给相应的系统。
另一方面，本发明提出了一种管理对参考点产生干扰的多个系统的第一设备，包括一个或多个处理器，所述处理器被配置为：基于与所述多个系统有关的信息，在所述多个系统中确定受到第二设备管理的一组系统；基于在所述参考点处允许的干扰上限，确定允许所述一组系统在所述参考点处产生的干扰总量；以及将所确定的干扰总量通知给所述第二设备，以使得所述第二设备能够基于所述干扰总量为所述一组系统中的每一个系统确定通信资源。
另一方面，本发明提出了一种由第二设备执行的用于管理对参考点产生干扰的多个系统的方法，所述方法包括：获取由第一设备确定的允许所述多个系统在所述参考点处产生的干扰总量；基于所获取的干扰总量，为所述多个系统中的每一个系统确定通信资源，以使得所述多个系统在利用所述通信资源进行通信时在所述参考点处产生的干扰彼此不同，并且所述多个系统产生的干扰之和不超过所述干扰总量；以及将为每一个系统确定的通信资源通知给相应的系统。
另一方面，本发明提出了一种由第一设备执行的用于管理对参考点产生干扰的多个系统的方法，所述方法包括：基于与所述多个系统有关的信息，在所述多个系统中确定受到第二设备管理的一组系统；基于在所述参考点处允许的干扰上限，确定允许所述一组系统在所述参考点处产生的干扰总量；以及将所确定的干扰总量通知给所述第二设备，以使得所述第二设备能够基于所述干扰总量为所述一组系统中的每一个系统确定通信资源。
另一方面，本发明提出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。

具体实施方式
图1示意地示出了本发明的技术方案所应用的通信场景，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，每个第一级频谱管理装置管理一定地理区域内的多个次系统。图1仅示意地示出了两个第一级频谱管理装置A1和A2，椭圆形虚线圈表示分别由第一级频谱管理装置A1和A2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比图1所示的更多或更少的第一级频谱管理装置。
在第一级频谱管理装置A1和A2各自的管理区域内存在多个次系统，该多个次系统可进一步受到不同的第二级频谱管理装置管理，图1 中示出了分别受第二级频谱管理装置B1管理的次系统221和受第二级频谱管理装置B2管理的次系统222。需要说明的是，在第一级频谱管理装置A1的管理区域内也可以存在不受任何第二级频谱管理装置管理的次系统(图中未示出)。
此外，图1中还示意地示出了主系统的覆盖区域以及在该覆盖区域的边缘处的参考点R。可以将主系统覆盖区域距离次系统覆盖区域最近的位置设置为参考点R。参考点R可以代表主系统受到次系统干扰最强的位置。因此，将次系统对主系统造成的干扰控制在主系统所允许的范围之内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A1和A2用于为其管理区域内的次系统分别分配可用的通信资源。第一级频谱管理装置A1和A2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B1和B2在为每个次系统分配的可用通信资源的范围内进一步为该次系统确定要使用的通信资源。第二级频谱管理装置B1和B2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B1和B2不对其管理的次系统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分配的可用通信资源的范围内进一步确定将由该次系统使用的通信资源。
如上所述，在第一级频谱管理装置A1和A2的管理区域内可以存在不受任何第二级频谱管理装置管理的次系统，这样的次系统在第一级频谱管理装置所分配的可用通信资源中自行选择用于通信的资源。然而，此时容易出现以下问题：位置较为接近的两个次系统可能会选择相同的资源进行通信，从而互相产生干扰。第二级频谱管理装置可用于解决该问题。由于第二级频谱管理装置在为每个次系统分配的可用通信资源的范围内为该次系统确定实际使用的通信资源，因此可以有效地避免各个次系统由于使用相同资源而互相干扰的可能性。
以下结合图2来描述根据本发明的第一实施例的分配通信资源的信令交互流程。
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该次系统的标识(ID)和位置信息。此外，对于受到第二级频谱管理装置B管理的次系统220而言，所发送的请求消息还可以包括与第二级频谱管理装置B有关的信息，例如第二级频谱管理装置B的标识(ID)和/或管理机制等等。例如，第二级频谱管理装置B的管理机制可以包括动态频谱感知，载波侦听多路访问(CSMA)，长期演进-先听后说(LTE-LBT)等。
第一级频谱管理装置A在接收到来自次系统210，220的请求消息后，可基于该请求消息中包含的信息来确定该次系统可用的通信资源，如步骤S220所示。在本文中，通信资源可以包括例如时间资源、频谱资源，最大发射功率等等。
针对不受第二级频谱管理装置B管理的次系统210，第一级频谱管理装置A可以在步骤S220例如根据可供分配的频谱资源、主系统的要求(例如在参考点R处可接受的信号与干扰加噪声比)以及次系统210到主系统的路径损耗来确定用于该次系统210的可用通信资源。需要说明的是，本领域技术人员易于理解第一级频谱管理装置A还可基于其他因素来确定次系统210的可用通信资源。然后，第一级频谱管理装置A在步骤S230将所确定的可用通信资源通知给次系统210，次系统210在步骤S240在接收到的可用通信资源中选择用于进行通信的特定资源。
针对受到第二级频谱管理装置B管理的次系统220，以下将分别以频谱资源和最大发射功率作为通信资源的两个示例来描述第一级频谱管理装置A在步骤S220中为次系统220确定可用通信资源的处理。
图3示出了为次系统220分配可用频谱资源的处理流程。第一级频谱管理装置A在接收到来自多个次系统220的请求消息后，可以根据该请求消息确定每个次系统220的标识和位置信息，以及该次系统220与对该次系统220进行管理的第二级频谱管理装置B之间的对应关系。进而，第一级频谱管理装置A可以将属于同一个第二级频谱管理装置B管理的多个次系统220分为一组，如步骤S310所示。然后，针对每一个组，第一级频谱管理装置A可以根据该组中的各个次系统的位置信息来确定该组次系统的分布区域，如步骤S320所示。
图4示意地示出了由第一级频谱管理装置A确定的两组次系统的分 布区域R1和R2，其中，区域R1中的次系统221受到第二级频谱管理装置B1(未示出)管理，区域R2中的次系统222受到第二级频谱管理装置B2(未示出)管理。如图4所示，分布区域R1和R2之间存在重叠区域(阴影部分)，重叠区域中同时存在有次系统221和次系统222。需要说明的是，图中仅在重叠区域中示意地示出了一个次系统221和一个次系统222，但重叠区域中可以存在一组多个次系统221和一组多个次系统222。
在图3的步骤S330中，第一级频谱管理装置A可以例如根据分布区域R1和R2的顶点位置，来确定该重叠区域。图中将分布区域R1和R2示出为矩形，但分布区域也可以是除矩形之外的任意多边形，多边形的两条相邻的边的公共端点称为多边形的顶点。第一级频谱管理装置A可以采用本领域技术人员已知的多种方法来确定每组次系统的分布区域以及多个分布区域之间的重叠区域，本发明对此不做限制。
然后，对于处于非重叠区域中的次系统而言，以处于区域R1的非重叠区域中的次系统221为例，由于这些次系统221受到同一个第二级频谱管理装置B1管理，因此它们的频谱分配可以由该第二级频谱管理装置B1协调处理，以避免它们由于使用相同频谱而相互产生干扰。在此情况下，第一级频谱管理装置A可以仅考虑可供分配的频谱资源来为该非重叠区域中的次系统221分配可用频谱资源，如步骤S340所示。对于处于区域R2的非重叠区域中的次系统222而言，处理方法相同。
对于处于重叠区域中的次系统221和次系统222而言，第一级频谱管理装置A除了考虑可供分配的频谱资源之外，还考虑第二级频谱管理装置B1和B2的管理机制来为次系统221，222分配可用频谱资源，如步骤S350所示。
具体来说，如果第二级频谱管理装置B1和B2均具有应对干扰的管理机制，例如均支持载波侦听避让，则第一级频谱管理装置A可以为重叠区域中的所有次系统221，222分配相同的可用频谱资源。然后通过第二级频谱管理装置B1和B2各自的干扰管理机制来避免两组次系统之间的相互干扰。
如果第二级频谱管理装置B1和B2中的至少一个不具有应对干扰的管理机制，即，无法应对来自另一第二级频谱管理装置所管理的次系统的干扰，则第一级频谱管理装置A可以为重叠区域中的(一组)次系统221和(一组)次系统222分别分配不同的频谱资源。
需要说明的是，步骤S340和步骤S350的执行顺序不限于图3中所示，而是可以以相反的顺序来执行或同时执行。此外，如果不存在非重叠区域或不存在重叠区域，则可以省略步骤S340或步骤S350的处理。
以下进一步讨论除了第一级频谱管理装置A之外，还存在另一个第一级频谱管理装置(称为第一级频谱管理装置A')的情况。
第一级频谱管理装置A'管理与第一级频谱管理装置A不同的地理区域，其在接收到来自多个次系统220的请求消息后执行与第一级频谱管理装置A类似的操作。例如，图5示意地示出了由第一级频谱管理装置A'确定的两组次系统的分布区域R3和R4，其中区域R3中的次系统221受到第二级频谱管理装置B1(未示出)管理，区域R4中的次系统222受到第二级频谱管理装置B2(未示出)管理。如图5所示，分布区域R3和R4之间不存在重叠区域。
然后，第一级频谱管理装置A和第一级频谱管理装置A'之间可以进行信息交互。所交互的信息可以例如包括：管理每个次系统的第二级频谱管理装置的标识(ID)和/或管理机制(如动态频谱感知，CSMA，LTE-LBT)，所确定的每组次系统的分布区域的位置信息(例如区域顶点的位置信息)。
在进行信息交互后，第一级频谱管理装置A和第一级频谱管理装置A'中的每一个频谱管理装置可以获知在对方所管理的地理区域中的多组次系统的分布情况，从而可以确定在二者管理的区域(更全面的区域)中多组次系统的重叠分布区域。例如，图6示意地示出了在第一级频谱管理装置A和A'二者的管理区域中各组次系统的分布区域，其中区域R1和R3中的次系统221受到第二级频谱管理装置B1(未示出)管理，区域R2和R4中的次系统222受到第二级频谱管理装置B2(未示出)管理。在阴影部分所表示的重叠区域中，存在着受到第二级频谱管理装置B1管理的次系统221以及受到第二级频谱管理装置B2管理的次系统222。
针对重叠区域中的次系统221，222，由第一级频谱管理装置A或第一级频谱管理装置A'根据第二级频谱管理装置B1和B2的管理机制来确定可用频谱资源。与上文所述类似地，如果第二级频谱管理装置B1和B2均具有应对干扰的管理机制，则可以为重叠区域中的所有次系统分配相同的可用频谱资源。如果第二级频谱管理装置B1和B2中的至少一个不具有应对干扰的管理机制，则为第二级频谱管理装置B1管理的一组次 系统221和第二级频谱管理装置B2管理的一组次系统222分配不同的可用频谱资源。
在确定了可用频谱资源之后，再次参考图2，第一级频谱管理装置A在步骤S250将针对次系统220(包括次系统221和次系统222)确定的可用频谱资源通知给管理该次系统220的第二级频谱管理装置B(包括第二级频谱管理装置B1和B2)。随后在步骤S260，相应的第二级频谱管理装置B在所接收的可用频谱资源的范围内为该次系统220确定用于进行通信的频谱资源。第二级频谱管理装置B的频谱资源分配使得其所管理的各个次系统220的通信质量最佳而同时产生最小的干扰。然后第二级频谱管理装置B在步骤S270将所确定的频谱资源通知给相应的次系统220。
以上以频谱资源为例描述了分配通信资源的处理，以下将以发射功率作为通信资源的一个示例来描述为次系统分配通信资源的处理。在确定次系统的发射功率时，需要考虑次系统对主系统产生的干扰。
图7示出了为受到第二级频谱管理装置B管理的次系统220确定可用通信资源的处理流程。参照图7，首先，第一级频谱管理装置A在步骤S710确定在主系统覆盖区域中的参考点R处(如图1中所示)所允许的干扰上限I limit。干扰上限I limit表示在保证主系统的通信质量的前提下，在最接近于次系统分布区域的参考点R处允许次系统对主系统造成的干扰的上限。例如，第一级频谱管理装置A可以基于预先存储的有关主系统的信息来确定该干扰上限I limit。
除了确定参考点R处的干扰上限I limit，第一级频谱管理装置A还确定自身所管理的地理区域内的次系统的数目N。假设该N个次系统中包括N1个由第二级频谱管理装置B1管理的次系统以及N2个由第二级频谱管理装置B2管理的次系统，即N＝N1+N2。然后，第一级频谱管理装置A在步骤S720通过下式来计算允许每个次系统对参考点R产生的最大干扰量I：
I＝I limit/N.
然后，第一级频谱管理装置A可以在步骤S730确定允许第二级频谱管理装置B1所管理的N1个次系统产生的最大干扰总量为I limit*N1/N，以及允许第二级频谱管理装置B2所管理N2个次系统产生的最大干扰总量为I limit*N2/N。
对于每个次系统而言，基于所允许产生的最大干扰量I、该次系统与参考点R之间的距离以及路径损耗，可以确定该次系统的最大发射功率。也就是说，干扰量与发射功率之间存在关联关系。因此，第一级频谱管理装置A为一组次系统(例如，上述N1个次系统或N2个次系统)确定的可允许的最大干扰总量可被认为是对应于该组次系统的可用通信资源。
在确定了可用通信资源之后，返回参考图2，第一级频谱管理装置A将对应于N1个次系统的最大干扰总量I limit*N1/N作为可用通信资源通知给第二级频谱管理装置B1，将对应于N2个次系统的最大干扰总量I limit*N2/N作为可用通信资源通知给第二级频谱管理装置B2，如步骤S250所示。
随后，第二级频谱管理装置B1和B2基于接收到的最大干扰总量为自身管理的一组次系统中的每个次系统确定可允许的最大干扰量，如步骤S260所示。以第二级频谱管理装置B1为例，其基于接收到的最大干扰总量I limit*N1/N来为自身管理的N1个次系统中的每一个确定可允许产生的最大干扰。其中，允许各个次系统产生的最大干扰可以相互不同，只要满足N1个次系统产生的最大干扰之和小于或等于最大干扰总量I limit*N1/N即可。例如，可以允许N1个次系统中的一个或多个次系统产生大于I limit/N的干扰，而同时其它次系统所产生的干扰则需要小于I limit/N，以使得N1个次系统在参考点R处引起的聚合干扰不大于由第一级频谱管理装置A1确定的最大干扰总量I limit*N1/N。
对于次系统而言，允许产生较大干扰意味着可以使用更大的发射功率，而允许产生的干扰较小则意味着需要限制发射功率。第二级频谱管理装置B1通过以此种方式分配可允许的最大干扰量，可以灵活地设置各个次系统的最大发射功率。例如，一组次系统中的需要高带宽以支持高速数据传输的次系统的最大发射功率可以被设置得更高，同时限制其他次系统的最大发射功率，在此情况下，该组次系统对参考点R产生的聚合干扰仍可以被控制在主系统所允许的范围之内。
然后，第二级频谱管理装置B1在步骤S270将所确定的可允许的最大干扰通知给相应的次系统220，使得该次系统220能够根据可允许的最大干扰、自身距参考点R的距离以及路径损耗来确定最大发射功率。替代地，根据允许每个次系统220产生的最大干扰来确定最大发射功率的操作也可以由第二级频谱管理装置B1来执行，并且第二级频谱管理装 置B1可以在步骤S270将所确定的最大发射功率通知给相应的次系统220。
图8示出了根据本发明的第二实施例的分配通信资源的信令交互图。如图8所示，在步骤810，次系统(包括不受第二级频谱管理装置B管理的次系统810以及受到第二级频谱管理装置B管理的次系统820)向第一级频谱管理装置A发送用于请求分配通信资源的请求消息。
与结合图2所描述的第一实施例类似地，在本实施例中请求消息可以包括次系统的位置信息，并且可以进一步包括与管理次系统820的第二级频谱管理装置B有关的信息(如ID，管理机制等)。
第一级频谱管理装置A在步骤S820基于接收到的请求消息，为次系统确定可用的通信资源。与结合图2所描述的第一实施例类似地，针对不受第二级频谱管理装置B管理的次系统810，第一级频谱管理装置A可以例如根据可供分配的频谱资源、主系统的要求(例如在参考点R处可接受的信号与干扰加噪声比)以及次系统810到主系统的路径损耗来确定用于次系统810的可用通信资源，并在步骤S830将所确定的可用通信资源通知给次系统810，然后次系统810可以在步骤S840从可用通信资源中选择特定资源以进行通信。
针对受到第二级频谱管理装置B管理的次系统820，第一级频谱管理装置A在步骤S820可以以第一实施例中描述的方式来为次系统820确定可用的通信资源。例如，针对由同一个第二级频谱管理装置B管理的一组次系统820，第一级频谱管理装置A可以确定对应于该组次系统的最大干扰总量(I limit*N1/N)，并且在步骤S850将该最大干扰总量作为可用通信资源通知给该组次系统中的各个次系统820。此外，第一级频谱管理装置A在步骤S850还可以将针对每个次系统820确定的最大干扰量(I limit/N)通知给相应的次系统820。
随后，每个次系统820在步骤S860将所接收的对应于一组次系统的可用通信资源以及为其单独确定的可用通信资源发送至对其进行管理的第二级频谱管理装置B。
与第一实施例类似地，第二级频谱管理装置B在步骤S870可以根据接收到的对应于一组次系统的最大干扰总量，来为该组中的每个次系统确定可允许产生的最大干扰，其中，可以允许各个次系统产生的最大干扰相互不同，只要满足各个次系统产生的最大干扰之和不超过最大干 扰总量即可。与第一实施例的区别在于，在此过程中，第二级频谱管理装置B还需要考虑接收到的对应于每个次系统的最大干扰量。
然后，第二级频谱管理装置B在步骤S880将为每个次系统820所确定的通信资源通知给相应的次系统820，以使得该次系统820能够利用该通信资源进行通信。例如，第二级频谱管理装置B在步骤S880可以将为每个次系统820确定的可允许的最大干扰作为通信资源通知给相应的次系统820，使得该次系统820能够根据该可允许的最大干扰、自身距参考点R的距离以及路径损耗来确定最大发射功率。替代地，根据可允许的最大干扰来确定最大发射功率的操作也可以由第二级频谱管理装置B来执行，并且第二级频谱管理装置B可以在步骤S880将所确定的最大发射功率作为通信资源通知给相应的次系统820。
本文中所描述的各个设备或单元仅是逻辑意义上的，并不严格对应于物理设备或实体。例如，本文所描述的每个单元的功能可能由多个物理实体来实现，或者，本文所描述的多个单元的功能可能由单个物理实体来实现。此外需要说明的是，在一个实施例中描述的特征、部件、元素、步骤等并不局限于该实施例，而是也可应用于其它实施例，例如替代其它实施例中的特定特征、部件、元素、步骤等，或者与其相结合。
在上述实施例中描述的一系列处理可以由软件、硬件或者软件和硬件的组合来实现。包括在软件中的程序可以事先存储在每个设备的内部或外部所设置的存储介质中。作为一个示例，在执行期间，这些程序被写入随机存取存储器(RAM)并且由处理器(例如CPU)来执行，从而实现在本文中描述的各种处理。

在具有上述结构的计算机中，CPU 901将存储在存储单元908中的程序经由输入/输出接口905和总线904加载到RAM 903中，并且执行该程序，以便执行上述处理。
要由计算机(CPU 901)执行的程序可以被记录在作为封装介质的移动介质911上，该封装介质以例如磁盘(包括软盘)、光盘(包括压缩光盘-只读存储器(CD-ROM))、数字多功能光盘(DVD)等)、磁光盘、或半导体存储器来形成。此外，要由计算机(CPU 901)执行的程序也可以经由诸如局域网、因特网、或数字卫星广播的有线或无线传输介质来提供。
当移动介质911安装在驱动器910中时，可以将程序经由输入/输出接口905安装在存储单元908中。另外，可以经由有线或无线传输介质由通信单元909来接收程序，并且将程序安装在存储单元908中。可替选地，可以将程序预先安装在ROM 902或存储单元908中。
要由计算机执行的程序可以是根据本说明书中描述的顺序来执行处理的程序，或者可以是并行地执行处理或当需要时(诸如，当调用时)执行处理的程序。
