Description

干扰处理装置、基站、用户设备及干扰处理系统和方法 技术领域
本发明实施例涉及通信技术,尤其涉及一种干扰处理装置、基站、用户设备及干扰处理系统和方法。
背景技术
传统的无线通信网络采用同构网络的形式,以基站(Base Station,简称为:BS)为网络中的基础设施形成的蜂窝网络中,每个小区的边缘用户通常受到较强的干扰,该干扰主要来源于相邻小区中的宏基站。因此,可以通过在相邻宏蜂窝边缘采取正交分配资源的方式,来提高小区边缘用户的服务质量,而小区的中心用户可以复用相邻小区边缘的资源,以提高资源的利用率。
目前的长期演进(Long Term Evolution,简称为:LTE)系统主要通过小区干扰协调(Inter-Cell Interference Coordination,简称为:ICIC)进行干扰管理和控制,该方式通过管理无线资源使得小区间干扰得到控制,通常考虑多个小区中资源使用和负载等情况而进行的多小区无线资源管理方案。具体地,ICIC从资源协调方式上通常包括:部分频率复用、软频率复用和全频率复用三类,举例来说,如图1所示的现有技术的ICIC所提供的部分频率复用的示意图,可以看出,小区的中心用户使用相同的频率资源fc,不同小区的边缘用户使用不同的频率资源,分别为f1、f2和f3,即每个小区只能使用全部资源的一部分;再举例来说,如图2所示的现有技术的ICIC所提供的软频率复用的示意图,可以看出,所有小区使用全部的频率资源,只是在不同的小区的边缘用户使用不同的频率资源,分别为f1、f2和f3,并加大发射功率,而在小区内使用剩余的全部频率资源。显然地,通过ICIC进行的干扰协调,主要解决的是小区边缘用于的干扰问题。
随着无线网络的业务类型和数据量的增加,由于异构网络的分层网络结构和多种类型的网元可以更好的适应和匹配多样化的业务需求,因 此已逐步取代同构网络应用无线通信系统中;由于异构网络中小站(Small cell)的密集部署,使得干扰问题更加突出,但是现有技术中通过ICIC进行干扰处理的方式,无法解决异构网络中用户的干扰问题。

具体实施方式
为使本发明实施例的目的、技术方案和优点更加清楚,下面将结合本发明实施例中的附图,对本发明实施例中的技术方案进行清楚、完整地描述,显然,所描述的实施例是本发明一部分实施例,而不是全部的实施例。基于本发明中的实施例,本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例,都属于本发明保护的范围。
传统的无线通信网络通过业务速率和发送功率相同或相近的BS形成同构网络的结构,例如以BS为网络中基础设施的蜂窝网络中,通常由运营商大规模部署BS,满足了室外网络的覆盖需求,随着无线通信网络中业务量和业务类型的增加,以及业务速率的提升,多媒体业务的海量传输与低带宽、高误码率的无线信道之间的矛盾对无线通信传输构成了巨大挑战;因此,传统的蜂窝网络已经不能够满足这些要求。异构网络成为解决上述业务需求的一个有效方法,异构网络的分层网络结构和多种类型的网元可以更好的适应和匹配未来多种多样的业务需求,实现负载均衡和业务分流,更加灵活高效的使用资源,增强网络的弹性,更好的提升用户的服务质量,实现以BS为中心的网络向用户设备(User Equipment,简称为:UE)为中心的网络的转变。
上述已经说明,在传统的蜂窝网络中可以通过ICIC进行干扰管理和控制,ICIC从资源协调方式包括上述部分频率复用、软频率复用和全频率复用三类。具体地,例如在LTE系统中,ICIC测量包括上下行的测量,其中上行测量标识有HII和OI指示,下行测量有RNTP指示,可以通过 演进型基站(Evolved Node B,简称为:eNodeB)之间的X2接口,传递上行强干扰指示器(High Interference Indicator,简称为:HII)和过载指示器(Overload Indicato,简称为:OI)指示,以及下行相对窄带发射功率(Relative Narrowband Transmission Power,简称为:RNTP)指示,本小区eNodeB通过接收的邻小区eNodeB发送的HII、OI和RNTP指示,判断上行和下行的资源块(Resource Block,简称为:RB)是否可用,以及具体使用方式。
举例来说,在下行链路中,ICIC主要通过RNTP来实现,RNTP指示主要用于调度时确定小区的边缘UE使用哪些RB,即本小区的边缘UE尽量使用本小区指示给邻小区RNTP为1的RB,尽量不使用邻小区指示RNTP为1的RB,RNTP为1时指示本小区当前使用RB。通过eNodeB之间的交互,遍历相邻两个小区所使用的所有RB,确定各个eNodeB可以使用的资源来进行调度。通过ICIC进行的干扰控制方法,可以解决宏蜂窝中相邻小区间边缘UE的干扰问题,但却不能保证网络系统具有较高的性能;特别地,当小区的边缘UE数量较少时,相对的信令开销就比较大;由于ICIC算法主要解决小区边缘UE受到的干扰问题,因此并没有考虑小区覆盖范围内全部UE的干扰问题。
然而,在异构网络中,通常通过部署发射功率较低的小站(Small cell),即微基站来执行高速业务,即宏蜂窝(Macrocell)中可能部署了多个毫微微蜂窝(Femtocell),由于小站分布的随机性,因此很难采用针对传统宏蜂窝的优化干扰处理方法对异构网络进行管理和优化。例如,考虑在单一的宏基站覆盖范围内存在多个小站分布的情况,由于小站与UE都是随机分布的,如何协调和分配资源,将直接关系到UE的干扰,通过ICIC进行干扰处理的方式主要解决相邻的Macrocell之间的边缘UE的干扰问题,针对Macrocell内密集部署的Femtocell中的UE,则无法通过ICIC对其进行干扰控制。
下面以具体地实施例对本发明的技术方案进行详细说明,图3为本发明实施例所提供的一种网络系统的示意图,本发明考虑Macrocell和Femtocell共存的两层网络,如图3所示,本发明各实施例中的所述的第一BS为蜂窝网络中的宏基站,形成具有单一覆盖范围的Macrocell,第二BS 为部署于上述第一BS覆盖范围内的微基站,每个第二BS在上述Macrocell的范围内形成Femtocell,以提供高速业务,并且每个第二BS的位置是随机分布的;其中,图3所示网络系统例如为LTE系统,第一BS为该系统中的宏基站,即eNodeB,其主要功能包括无线资源管理,无线承载控制,无线接纳控制,连接移动性控制和动态资源分配,eNodeB具有现有第三代合作伙伴计划(3rd Generation Partnership Project,简称为:3GPP)R5/R6/R7(即为3GPP的协议版本)中Node B的功能和大部分的无线网络控制器(Radio Network Controller,简称为:RNC)功能;第二BS即为第一BS覆盖范围内的微基站,具体为低功率的无线接入节点,通常可以覆盖10米(m)到200m的范围,相比之下,第一BS的覆盖范围可以达到数公里,该第二BS可以融合Femtocell,微微小区(Picocell),微蜂窝(Microcell)和分布式无线技术,例如射频拉远头(Remote Radio Head,简称为:RRH),微基站通常支持多种无线口标准,包括全球移动通信系统(Global System for Mobile Communication,简称为:GSM)、Code 3G移动通讯标准(Division Multiple Access 2000,简称为:CDMA2000)、时分同步码分多址(Time Division-Synchronous Code Division Multiple Access,简称为:TD-SCDMA)、宽带码分多址(Wideband Code Division Multiple Access,简称为:WCDMA)、LTE和全球微波互联接入(Worldwide Interoperability for Microwave Access,简称为:WiMax)。本发明以下各实施例所涉及的网络系统例如以正交频分多址(Orthogonal Frequency Division Multiple Access,简称为:OFDMA)系统为例予以说明,该OFDMA系统在不同的UE接入相同的BS时,各个UE使用正交的资源,相邻Macrocell中的第一BS的发射功率通常相同,Femtocell中的第二BS的发射功率通常相同,并且第二BS的发射功率要小于第一BS的发射功率。
本发明提供以下几个具体的实施例可以相互结合,对于相同或相似的概念或过程可能在某些实施例不再赘述。
实施例一
图4为本发明实施例一所提供的一种干扰处理装置的结构示意图。本实施例的装置设置于第一BS中,如上述图3所示,该第一BS的覆盖范围内部署了多个第二BS,本实施例提供的装置具体包括:接收模块11、 计算模块12和确定模块13。
其中,接收模块11,用于接收第一BS覆盖范围内每个第二BS在每个RB上的最大传输速率,其中,每个第二BS在每个RB上的最大传输速率为通过接收接入第二BS的每个UE在每个RB上测得的最大传输速率所获取的。
本发明各实施例以第一BS的覆盖范围内部署了M个第二BS为例予以说明,即该第一BS形成的单个Macrocell覆盖范围内具有了M个Femtocell,该Macrocell中例如共有N个RB。在本实施例中,Macrocell覆盖范围内的UE可能接入第一BS,也可能接入不同的第二BS,考虑接入其中一个第二BS的UE的情况,即考虑标号为j的Femtocell中的情况,接入Femtocellj的UEp在RBi上的最大传输速率Cp,i为:
Cp,i=B·log2(1+SINRj,i)   (1)
其中,上述(1)式中的B是网络系统的带宽,SINRj,i是Femtocellj中的UEp在RBi上信干燥比(Signal to Interference plus Noise Ratio,简称为:SINR);通过上述(1)式可以看出,UE在每个RB上测得的最大传输速率,为该UE通过测量其自身在每个RB中的信干噪比SINR所得到的,在具体实现中,同样以接入Femtocellj的UEp为例予以说明,该UEp与Femtocellj中的第二BS之间的路径损耗ζp,j为:
Figure PCTCN2016079393-appb-000001
其中,上述(1-1)式中的dp,j为Femtocellj中的第二BS与UEp之间的距离,fc为载波频率,第二BS的载波频率由其自身的载波频点确定,d0为参考距离,通常取1m,c为常数,具体为光速。通过(1-1)式可以得到接入Femtocellj的UEp在RBi上接收到的功率Pj,i为:
Pj,i=PF·|hfj,i|2·ζp,j   (1-2)
其中,上述(1-2)式中的PF为Femtocellj中第二BS的发送功率,hfj,i为第二BS在在RBi上的瑞利衰落。
与上述(1-2)式类似地,可以的得到UEp接收到的来自Macrocell在RBi上的干扰信号的功率Pmacro,i为:
Figure PCTCN2016079393-appb-000002
其中,上述(1-3)式中的PM为第一BS的发送功率,hmacro,i为第二BS 在在RBi上的瑞利衰落,
Figure PCTCN2016079393-appb-000003
为UEp与第一BS之间的路径损耗。从而根据上述(1-1)式到(1-3)式可以计算出上述(1)式中的SINRj,i,具体为:
Figure PCTCN2016079393-appb-000004
其中,上述(1-4)式中的Ni为该UEp在RBi上的高斯白噪声的功率,将该(1-4)式代入(1)式中即可计算出接入Femtocellj的UEp在RBi上的最大传输速率Cp,i
需要说明的是,通过(1)式具体获取到的是接入Femtocellj的每个UE在每个RB上的最大传输速率;若要获取该Femtocellj中的第二BS在每个RB上的最大传输速率,则该第二BS可以通过接收接入该Femtocellj的每个UE在每个RB上的最大传输速率,将接入该Femtocellj的所有UE所测得的最大传输速率进行汇总,从而通过机会算法获取该Femtocellj中的第二BS在每个RB上的最大传输速率,以接入该Femtocellj的UE为ε个为例予以说明,该Femtocellj在RBi上的最大传输速率构成的集合中,元素的数目为ε,具体为C1,i,C2,i,…Cε,i,定义该Femtocellj在RBi上的最大传输速率μj,i为:
μj,i=max{Cp,i|p=1,2…ε}(Cp,i≥0)   (2)
其中,上述(2)式中的j为Femtocellj对应的标号,i为RBi对应的标号,当没有UE接入该Femtocellj时,μj,i=0;通过上述(1)式和(2)式可以确定出Femtocellj中的第二BS在每个RB上的最大传输速率;对于第一BS覆盖范围内的其它Femtocellk(k≠j)来说,同样可以通过上述方式获取每个Femtocell中的第二BS在每个RB上的最大传输速率,则该第一BS的接收模块11可以接收到该第一BS覆盖范围内每个第二BS在每个RB上的最大传输速率。
接收模块11,还用于通过接收接入第一BS的每个UE在每个RB上测得的最大传输速率,获取该第一BS在每个RB上的最大传输速率。
在本实施例中,对于Macrocell中的第一BS来说,第一BS获取其自身在每个RB上的最大传输速率与上述第二BS获取自身在每个RB上的最大传输速率的方式相同,并且接入该第一BS的每个UE在计算该UE在每个RB上的最大传输速率时,同样可以通过测量该UE在每个RB上的SINR进行计算,具体方式与上述通过(1-1)式到(1-4)式获取(1) 式的计算结果的方式类似,故在此不再赘述;不同在于,第一BS通过接入的每个UE在每个RB上测得的最大传输速率之后,不需要发送给其它BS,由该第一BS将获取的每个最大传输速率进行汇总后,通过机会算法获取该第一BS在每个RB上的最大传输速率。
计算模块12,用于计算每个RB的最大总传输速率,每个RB的最大总传输速率为每个第二BS在每个RB上的最大传输速率与第一BS在每个RB上的最大传输速率之和。
在本实施例中,第一BS在获取到其覆盖范围内的每个第二BS在每个RB上的最大传输速率,以及该第一BS在每个RB上的最大传输速率之后,可以进一步计算出该第一BS覆盖范围内的每个RB的最大总传输速率;具体地,根据上述(2)式可以得到矩阵A:
Figure PCTCN2016079393-appb-000005
其中,上述(3)式中的aj+1,i=μj,i,j为大于等于1的正整数,a1,i是Macrocell对应于RBi的最大传输速率;则可以获取到第i个RB的最大总传输速率Ri为:
Figure PCTCN2016079393-appb-000006
其中,上述(4)式中的ami为标号为(m-1)的Femtocell在RBi上的最大传输速率,m=2,3,……,M+1,通过上述(3)式和(4)式即可获取每个RB的最大总传输速率,例如可以通过向量R记录每个RB的最大总传输速率,即为:
R=(r1,r2,…rN)   (5)
确定模块13,用于根据计算模块12计算出的每个RB的最大总传输速率,确定干扰处理结果,该干扰处理结果包括使用最大总传输速率最高的部分RB进行资源复用。
在本实施例中,该干扰处理装置的确定模块13可以根据上述(5)式中记录的每个RB的最大总传输速率,确定出进行干扰处理的结果,从而通过该结果中确定的部分RB进行资源复用,该部分RB的最大总传输速率要大于其它未进行资源复用的RB的最大总传输速率,得以保证给进行 复用RB的UE提供较高的接收信号质量。本实施例在进行干扰处理结果的执行过程中,考虑到第一BS覆盖范围内的所有UE,无论是接入该第一BS的UE,还是接入其覆盖范围内部署的第二BS的UE,即在以第一BS和多个第二BS构成的Macrocell-Femtocell共存的两层网络系统中,通过获取该网络系统中的每个UE在每个RB上的测量结果,对该些UE进行干扰处理;相比于通过ICIC进行干扰处理时,仅考虑相邻宏基站的边缘UE的资源分配具有明显的优势,其一,考虑到第一BS覆盖范围内所有UE的干扰问题,全局考虑干扰的情况,从而适用于对异构网络进行干扰处理;其二,以图3所示的异构网络为例予以说明,每个第二BS都会受到周围多个第二BS的影响,若通过ICIC进行干扰处理,会产生比较大的信令开销,并且会导致资源利用率较低。
在本实施例中,进行资源复用的部分RB的是通过机会算法确定出的,并且每个第二BS或第一UE在获取其自身在每个RB上的最大传输速率时,也是基于机会算法执行的。虽然现有的多播系统已经采用机会算法执行相应的功能,例如,在多播系统中,为了满足最差用户的正确接收,多播的速率就是最差用户的接收速率,为了提高单次的接收速率,通过对用户接收速率排序,基于机会算法选取所有用户中部分最优用户先进行传输,即通过多次多播后,可以基本保证全部用户的正确接收,同时每次多播的速率都有很大提升。本发明各实施例则是将该机会算法应用于单播系统中,需要说明的是,多播系统的特点是广播特性,即BS每次向多个UE发送同样的内容,每次发送的功率相同,发送的方式较为简单,易于实现;若将机会算法应该于单播系统中,由于BS向每个UE发送的内容通常为不同的,因此发送方式也与多播系统中不同,本发明各实施例在应该机会算法是通过对发送方式的具体改进,以匹配单播系统的应该场景,从而实现第一BS覆盖范围内所有UE的干扰处理,以提供适应于整个网络系统的干扰协调方式。
本实施例提供的干扰处理装置,设置于第一BS中,该第一BS的覆盖范围内部署了多个第二BS,该干扰处理装置通过接收模块接收第一BS覆盖范围内每个第二BS在每个RB上的最大传输速率,以及接收接入该第一BS的每个UE在每个RB上测得的最大传输速率,从而通过计算模 块计算出每个RB的最大总传输速率,进而根据计算出的每个RB的最大总传输速率确定干扰处理的结果,即通过机会算法实现了对网络系统中的部分RB进行资源复用,本实施例提供的干扰处理装置在执行干扰处理时,通过机会算法进行计算时需要获取第一BS覆盖范围内的每个UE在每个RB上的测量结果,即在执行干扰处理时考虑到该第一BS覆盖范围内的所有UE的干扰问题,从而解决了现有技术中通过ICIC进行干扰控制的方式,无法解决异构网络中用户的干扰问题。
进一步地,本实施例相比于通过ICIC进行干扰处理,有效的较低了BS之间的信令开销,同时提高了资源利用率;另外,本实施例在通过机会算法获取每个第二BS或第一UE在每个RB上的最大传输速率,由于本发明各实施例的网络场景均为单播系统中的应该,因此,与多播系统中应用机会算法的方式不同,本实施例具体将机会算法的思维方式应用于单播系统中,以提供一种适用于异构网络的干扰处理装置。
可选地,图5为本发明实施例所提供的另一种干扰处理装置的结构示意图,在上述图4所示实施例的基础上,图5所示本实施例提供的干扰处理装置中,确定模块13可以包括:数量确定单元14,用于根据第一BS所属网络系统的当前信噪比(Signal to Noise Ratio,简称为:SNR),基于机会算法确定待进行资源复用的RB的数量为n个,其中,n≤N,N为RB的总数;结果确定单元15,用于根据计算模块12计算出的每个RB的最大总传输速率和数量确定单元14已确定的待进行资源复用的RB的数量,确定干扰处理结果,干扰处理结果具体包括使用最大总传输速率最高的n个RB进行资源复用。
本实施例在具体实现中,可以对上述(5)式中向量R记录每个RB的最大总传输速率按照降序对R进行排序,并将排序的结果记录在向量R′中,具体为:R′=(r′1,r′2,…r′N),其中,r′1≥r′2≥…≥r′N,同时,定义向量B记录向量R′各个元素在每个RB上的标号,即:B=(b1,b2,…,bN),其中,bi∈{1,2,…,N},从而该确定模块13根据第一BS所述网络系统中当前的SNR,选择n个RB进行资源复用,而这n个RB具体为b1,b2,…,bn,对应的速率分别为r′1,r′2,…,r′n
在本实施例中,确定模块13在确定干扰处理结果时,在充分考虑第 一BS所属网络系统中的当前SNR的同时,采用机会算法确定出进行资源复用的RB的数量,即确定模块13在计算模块12已获取到每个RB的最大总传输速率的基础上,通过机会算法获取上述最大总传输速率最高的n个RB,从而通过获取的该n个RB进行资源复用;显然地,由于该n个RB的最大总传输速率相对其它RB来说较高,进行资源复用时可以保证复用该n个RB的UE具有较好的接收信号质量,从而保证网络系统的性能。
进一步地,本实施例提供的干扰处理装置还包括发送模块16,用于向每个第二BS发送确定模块13确定出的干扰处理结果,干扰处理结果用于指示每个第二BS通过与最大总传输速率最高的n个RB对应的UE,对n个RB进行资源复用。需要说明的是,确定模块13确定出的干扰处理结果还可以包括使用最大总传输速率最低的N-n个RB进行正交分配,则干扰处理结果还用于指示每个第二BS对未进行资源复用的UE,采用N-n个RB进行正交分配。由此可以看出,对于网络系统中已分配的固定数量的RB,通过本实施例提供的干扰处理装置,最终可以确定出进行资源复用的RB的具体数量以及复用该n个RB的UE,以及进行正交分配的RB的具体数量以及对应于该N-n个RB的UE,上述结果是基于该网络系统中每个UE在每个RB上测得的SINR,以及网络系统的当前SNR所得到的,由于第一BS和所有第二BS复用全部资源,本实施例提供的装置通过汇总每个UE测得的结果,并基于机会算法筛选出每个RB的最大传输速率,考虑了网络系统的整体干扰情况,对干扰小的RB进行资源复用,对干扰强的RB进行正交分配,实现资源的动态复用。相比于现有技术中通过ICIC进行干扰处理的方式,通过机会算法可以动态的调整RB复用的比例,实现网络系统中全部UE的干扰协调。
在本实施例中,将资源复用和正交分配的使用方式相结合,可以更加灵活弹性的使用资源。举例来说,所有的BS在初始时刻是可以使用全部的RB,但通过RB信息、干扰情况的分析,部分RB可供多个UE同时使用,而剩余的RB则采用正交分配的使用方式,从而复用干扰小的RB,正交分配干扰大的RB;在实际使用中,通过这种方式,可以较好的跟踪RB的变化,判断干扰的情况,从而弹性使用资源,以实现资源与用户的 良好匹配。另外,通过网络侧的判断、分析,提供RB使用的分配方案。
具体地,该第一BS所述网络系统中,吞吐量的计算方式为:接收模块11,还用于获取第一BS覆盖范围内,进行资源复用的所有UE计算出的资源复用总速率,以及进行正交分配的所有UE计算出的正交分配总速率;相应地,计算模块12,还用于根据接收模块11获取的资源复用总速率和正交分配总速率,计算出第一BS网络系统的吞吐量。同样以上述图4和图5所示实施例中各计算公式对应的标号为例予以说明,上述进行资源复用的n个RB的总速率Co可以为:
Figure PCTCN2016079393-appb-000007
上述进行正交分配的N-n个RB的总速率Ct可以为:Ct=B·log2(1+SNR),其中,SNR为第一BS所属网络系统的当前SNR,则可以得出该网络系统的吞吐量为:
Figure PCTCN2016079393-appb-000008
通过上述(6)式计算出该第一BS所属网络系统的吞吐量,可以明确的体现出该网络系统具有较高的吞吐量,从而实现了该网络系统中资源的合理利用,并且可以保证系统总每个UE的业务速率以及整个网络系统的吞吐量。
本实施例将机会算法应用于小站密集分布的网络系统中,根据该网络系统总每个UE的干扰变化,可以动态的调度资源,在实现资源复用与正交分配的结合同时,可以保证系统的总吞吐量,使系统中的大多数的UE都得到比较高的传输速率。具体地,根据机会算法的选择特性,可以确定与资源匹配的最佳用户,实现资源与用户的良好匹配,保证了系统增益;而且由于RB的变化,经过几次机会算法后,单播系统也可以获得类似多播系统的增益,即系统中的大部分UE都可以以较高速率接受服务,从而挖掘了系统中资源的潜能,保证了用户的服务质量。与现有技术中通过ICIC进行干扰处理的方式相比较,本实施例通过机会算法并不 是简单的指示每个小区哪些资源可用,从而避免干扰,而是从整体考虑系统的吞吐量,同时考虑用户的传输速率,进行统一的调度分配,从而对于干扰小的RB进行复用,而对于干扰强的RB则采用正交分配,从而可以保证系统的整体性能。
本发明各实施例提供的干扰处理装置具体应用于上述图3所示的网络系统中,由于该系统中业务速率的差异较大,因此对不同速率的业务采用不同的机制,一方面可以更优化的使用资源,另一方面可以降低相关算法的复杂度,获得更好的增益。在此基础上,可以将业务进行分类,即为高速业务和低速业务,Femtocell提供高速业务,而Macrocell既可提供高速业务,也可提供低速业务;由于高速业务具有数据量大,对速率要求高等特点,因此需要使用较好的RB,本发明各实施例具体提出机会算法与正交分配相结合的资源分配策略,降低Macrocell与Femtocell之间的干扰。
具体地,在Macrocell覆盖区域内具有多个高速Femtocell的存在,且全部共用RB,因此Femtocell与Macrocell之间会产生比较强的干扰,并且,由于Macrocell在小区边缘选用特定频段,并且加大发射功率,故在Femtocell中有些RB的干扰可能会更大。在这种情况下,本发明各实施例采用机会算法,在OFDMA系统中,Femtocell与Macrocell共用各个RB,而且各RB相互正交,考虑到各个RB的衰落是变化的,所以机会算法可以弹性地使得系统为用户选择合适的RB进行资源复用。另外,由于每个用户在每个RB上的衰落和干扰是不同的,因此,机会算法是在追求系统容量最大的目标下,为每个RB选择最优的用户,即通过机会算法选出来的RB,由于受干扰程度小,可供Macrocell与多个Femtocell所共用,极大的提高了系统的容量,而对于剩余的RB,则可以根据干扰状况,分别分配给最优的用户。上述方法可以根据RB的情况,通过机会算法灵活的选择复用与正交分配的方式,既提高了频谱利用率,又降低了干扰。通过上述选择和分配,可以使所有的RB都得到最大化的利用,从而更好的提升系统的容量。
本发明各实施例所提出的机会算法强调的是资源与用户的匹配问题,重点解决宏蜂窝与其中部署的小站之间的干扰问题。现有技术中的 软频率复用是一种固定频率规划的复用机制,且主要应用于解决宏蜂窝之间的干扰,主要通过预先确定频率分配并调整发射功率实现,然而,对于小站密集分布的场景而言,软频率复用方式并不能解决干扰问题。而机会算法在共用RB的前提下,根据干扰状况的变化,动态的为每个BS分配RB,并同时确定使用RB的UE,即通过一种动态分配资源的方式解决了系统中资源的干扰存在动态性的问题。本发明各实施例通过机会算法在具体实现中,系统中的每个UE均参与,即通过收集用户侧的相关数据信息,获得每个小区在各个RB上的干扰情况,综合考虑整个系统的吞吐量,从而确定资源的调度方式,并将结果告知各个BS,确定最终的分配方式。
以下通过采用本实施例提供的干扰处理装置在网络系统处于不同SNR的条件下,对三种频率资源规划下的机会算法所确定出的干扰处理结果进行比较,该三种频率资源规划为完全正交(Orthogonal Allocation,简称为:OA),部分正交(partial reuse)和完全复用时的机会算法(Opportunistic Scheme,简称为:OPS),图6为本发明实施例所提供的一种资源分配与总速率的关系曲线图,图7为本发明实施例所提供的另一种资源分配与总速率的关系曲线图,图8为本发明实施例所提供的又一种资源分配与总速率的关系曲线图,上述图6到图8中,纵坐标表示第一BS所属的网络系统中所有RB的总速率,图6到图8为本实施例提供的干扰处理装置在网络系统处于不同SNR时得到的关系曲线图,图6中的SNR为2dB,图7中的SNR为18dB,图8中的SNR为28dB;在完全正交时,Macrocell与Femtocell之间,以及Femtocell之间均采用正交的资源,因此不存在同频干扰,考虑到Macrocell覆盖的范围较大,因此会给Macrocell分配较多的资源,而每个Femtocell分得的资源数相同,但这种方式使得所有的小区可使用的资源很少,因此整个系统的容量较小,并且RB的总速率为固定值,即图中的曲线OA与横坐标无关;在部分正交时,对于Macrocell与Femtocell之间,将所有的RB划分为两部分,一部分为Macrocell单独占用,另一部分为所有的Femtocell复用,采用机会算法进行分配,图中的横坐标表示Macrocell占用的资源的百分比;在完全复用时,Macrocell与Femtocell复用全部的RB,图中的横坐标表示通过 机会算法选取的n个RB占总RB的百分比,剩余的RB采用正交分配。
由上述图6到图8可以看出,随着SNR的提升,三种频率资源规划下的总速率都有提升,在低、中、高信噪比下,部分正交和完全复用时的性能要好于完全正交时的性能,主要原因在于部分正交和完全复用的方法都在一定程度上增大了系统可用RB的数目,即同一个RB可供多个用户使用,因此系统的整体性能更优。具体地,在低信噪比,完全复用的情况下,随着复用RB比例的提高,系统总速率越大,这是因为该复用RB可以供多个用户使用,即可服务的用户数就越多,整体性能也就越好,而在部分正交情况下,当Macrocell占用的RB越多时,Femtocell整体可使用的RB变少,因此复用RB的数变少,系统总速率也会随之下降;在中信噪比,完全复用的情况下,系统总速率的最大值并没有出现在复用RB为100%占用情况下,而是在60%-70%之间,这是由于此时SNR较大,噪声较小,而复用RB可提供给多个用户使用,这样用户间的同频干扰就会对系统的性能有一定的影响,因此峰值不会出现在100%占用情况下,而在部分正交情况下,由于复用RB的性能会受到同频干扰的影响,而Macrocell与Femtocell的资源正交性又可以避免干扰,因此虽然Macrocell占用资源的百分比在变化,但系统的性能变化不大,而完全正交的条件下,系统总速率随SNR的提升而增大;在高信噪比,完全复用的情况下,系统总速率是逐步降低的,这是因为此时噪声的影响很小,而由复用RB产生的同频干扰将占据主导地位,因此随着复用RB比例的增大,同频干扰也将增大,因此整体性能会下降,在部分正交的情况下,随着Macrocell占用的RB比例增大,整体的Femtocell可用RB的数量减小,即复用RB的数量减小,因此同频干扰较小,从而系统总速率上升,完全正交的情况下,完全消除了同频干扰,因此系统的性能相较之前提升了很多。另外,无论系统当前的SNR的高低,完全正交的情况下,由于Macrocell以及各个Femtocell占用的RB是确定的,因此不存在比例问题,故关系曲线OA是一条没有变化的直线。
进一步地,图9为本发明实施例所提供的一种SNR与总速率的关系曲线图,图9中示出了随着SNR的变化,上述三种频率资源规划下系统总速率的变化曲线,由图9中的三条曲线的走势可看出,随着SNR的增 加,系统总速率是增加的,然而,采用复用RB的系统性能要优于采用正交分配RB的系统性能,这是由于通过机会算法确定复用RB时,在考虑干扰的情况下,最大化了各个RB的总速率,从而提升了系统的性能,而且在SNR不同的条件下,通过机会算法确定出的复用RB的比例也是不同。

在本实施例中,由于最终确定干扰处理结果的网元为该网络系统中的第一BS,因此,该第一BS覆盖范围内的每个第二BS中的发送模块22均要将上述获取的其自身在每个RB上的最大传输速率发送给第一BS,同时本实施例中的第一BS同样需要获取其自身在每个RB上的最大传输速率,具体的实现方式与某个第二BS获取该第二BS在每个RB上的最大传输速率的方式相同,从而第一BS根据其自身获取的数据和每个第二BS获取的数据,通过计算每个RB的最大总传输速率来确定干扰处理结果,即本实施例中每个RB的最大总传输速率同样可以通过上述(3)式和(4)式计算得出,也可以通过上述(5)式来记录该每个RB的最大总传输速率,从而实现通过该结果中确定的部分RB进行资源复用,该部分RB的最大总传输速率要大于其它未进行资源复用的RB的最大总传输速率,得以保证给进行复用RB的UE提供较高的接收信号质量。

进一步地,本实施例相比于通过ICIC进行干扰处理,有效的较低了BS之间的信令开销,同时提高了资源利用率;另外,本实施例在通过机会算法获取每个第二BS或第一UE在每个RB上的最大传输速率,由于本发明各实施例的网络场景均为单播系统中的应该,因此,与多播系统中应用机会算法的方式不同,本实施例具体将机会算法的思维方式应用于单播系统中,以提供一种适用于异构网络的干扰处理装置。
可选地,本实施例提供的干扰处理装置中,发送模块22具体用于向第一BS发送接收模块21获取的第二BS在每个RB上的最大传输速率,以指示第一BS根据第一BS所属网络系统的当前信噪比SNR,基于机会算法确定待进行资源复用的RB的数量为n个,并根据每个RB的最大总传输速率和已确定的待进行资源复用的RB的数量,确定干扰处理结果,其中,n≤N,N为RB的总数,干扰处理的结果具体包括使用最大总传输速率最高的n个RB进行资源复用。本实施例中确定n个RB的具体方式与上述实施例相同,故在此不再赘述。
图11为本发明实施例所提供的又一种干扰处理装置的结构示意图,在上述图10所示实施例的基础上,图11所示本实施例提供的干扰处理装置还包括:记录模块23,用于在接收模块21获取第二BS在每个RB上的最大传输速率之后,记录与第二BS在每个RB上的最大传输速率对应的UE;相应地,接收模块21,还用于接收第一BS发送的干扰处理结果;该干扰处理装置还可以包括:处理模块24,用于根据接收模块21接收到的干扰处理结果,从记录模块23记录的UE中选取与最大总传输速率最高的n个RB对应的UE,对n个RB进行资源复用。
进一步地,在本实施例中,接收模块21接收到的干扰处理结果还包括使用最大总传输速率最低的N-n个RB进行正交分配;相应地,处理模块24,还用于根据接收模块21接收到的干扰处理结果,对接入第二BS中未进行资源复用的UE,采用N-n个RB进行正交分配。由此可以看出,对于网络系统中已分配的固定数量的RB,通过本实施例提供的干扰处理装置,最终可以确定出进行资源复用的RB的具体数量以及复用该n个RB的UE,以及进行正交分配的RB的具体数量以及对应于该N-n个RB的 UE,上述结果是基于该网络系统中每个UE在每个RB上测得的SINR,以及网络系统的当前SNR所得到的,由于第一BS和所有第二BS复用全部资源,本实施例提供的装置通过汇总每个UE测得的结果,并基于机会算法筛选出每个RB的最大传输速率,考虑了网络系统的整体干扰情况,对干扰小的RB进行资源复用,对干扰强的RB进行正交分配,实现资源的动态复用。

在本实施例中,发送模块32将测量模块31测得的结果,即UE在每个RB上的最大传输速率进行上报,需要注意的是,发送模块32根据其所属UE所接入的BS进行上报,即若该UE接入第一BS,则将测量的结果发送给第一BS,若该UE接入某个第二BS,则将测量的结果发送给该第二BS,由于本实施例的网络系统中包括多个UE,即包括多个本实施例提供的干扰处理装置,网络系统中的第一BS和多个第二BS可以接收到不同UE发送的测量结果,并通过接收到的测量结果分别获取其自身在每个RB上的最大传输速率,每个第二BS或第一BS获取其自身在每个RB上的最大传输速率的方式,与上述实施例中相同,即通过上述(1)式和(2)式即可得到;另外,第二BS还要将其获取到结果发送给第一BS,从而使得第一BS计算出其所属网络系统中每个RB的最大总传输速率,本实施例中每个RB的最大总传输速率同样可以通过上述(3)式和(4)式计算得出,也可以通过上述(5)式来记录该每个RB的最大总传输速率,从而实现通过该结果中确定的部分RB进行资源复用,该部分RB的最大总传 输速率要大于其它未进行资源复用的RB的最大总传输速率,得以保证给进行复用RB的UE提供较高的接收信号质量。
类似地,本实施例中进行资源复用的部分RB的是通过机会算法确定出的,并且每个第二BS或第一UE在获取其自身在每个RB上的最大传输速率时,也是基于机会算法执行的。

进一步地,本实施例相比于通过ICIC进行干扰处理,有效的较低了BS之间的信令开销,同时提高了资源利用率;另外,本实施例在通过机会算法获取每个第二BS或第一UE在每个RB上的最大传输速率,由于本发明各实施例的网络场景均为单播系统中的应该,因此,与多播系统中应用机会算法的方式不同,本实施例具体将机会算法的思维方式应用于单播系统中,以提供一种适用于异构网络的干扰处理装置。
可选地,本实施例提供的干扰处理装置中,发送模块32通过发送测量模块31测得的UE在每个RB上的最大传输速率,以指示第一BS确定干扰处理结果的具体方式为:将测量模块31测得的UE在每个RB上的最大传输速率发送给第一BS或第二BS,以指示第一BS根据第一BS所属网络系统的当前信噪比SNR,基于机会算法确定待进行资源复用的RB的数量为n个,并根据每个RB的最大总传输速率和已确定的待进行资源复 用的RB的数量,确定干扰处理结果,其中,n≤N,N为RB的总数,干扰处理的结果包括使用最大总传输速率最高的n个RB进行资源复用。本实施例中确定n个RB的具体方式与上述实施例相同,故在此不再赘述。
