Description

一种干扰控制方法及装置
本申请要求于2022年09月27日提交国家知识产权局、申请号为202211181103.3、申请名称为“一种干扰控制方法及装置”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
本申请实施例涉及通信领域,尤其涉及一种干扰控制方法及装置。
背景技术
第五代(5th generation,5G)移动通信技术(mobile communication technology)是具有高速率、低时延、和大连接等特点的新一代宽带移动通信技术,是实现人机物互联的网络基础设施。随着5G用户渗透率的提升、业务量的增加,5G网络中的干扰也会增加,从而导致用户体验下降。为了保证用户体验,进行干扰控制是必然选择。
目前,常用的一种干扰控制方案为基于物理小区标识(physical cell identifier,PCI)模3的频域干扰随机化方案。其基本原理是:小区的PCI对3取模后的不同值,对应不同的频域资源起始位置。即,不同小区的PCI对3取模后的值不同时,各个小区待调度的频域资源的起始位置不同。
然而,从现网的统计数据来看,基于PCI模3的干扰随机化方案中,干扰避让效果较差。
发明内容
本申请提供一种干扰控制方法及装置,可以提高干扰控制效率,进而降低干扰,提升用户体验。
第一方面,提供了一种干扰控制方法,该方法可以由网络设备执行,也可以由网络设备的部件,例如网络设备的处理器、芯片、或芯片系统等执行,还可以由能实现全部或部分网络设备功能的逻辑模块或软件实现。该方法包括:获取第一小区的多个同步信号块SSB波束对应的频域资源起始位置,其中,至少两个SSB波束对应的频域资源起始位置不同;确定第一终端设备对应的业务波束,该业务波束关联多个SSB波束中的第一SSB波束。通过该业务波束在第一频域资源上为第一终端设备提供服务,第一频域资源的起始位置为第一SSB波束对应的频域资源起始位置。
基于该方案,网络设备可以确定SSB波束级的频域资源起始位置,将SSB波束对应的频域资源起始位置作为其对应的业务波束的频域资源起始位置,通过该业务波束在该频域资源起始位置上为终端设备提供服务。也就是说,网络设备可以通过SSB波束对应的频域资源起始位置指导业务波束的频域资源起始位置的配置,实现业务波束的波束级频域资源起始位置的配置,从而实现精细化的频域起始位置错开,提高干扰控制效率,进而降低干扰,提升用户体验。
在一种可能的设计中,确定第一小区的多个SSB波束对应的频域资源起始位置,包括:确定至少一个SSB波束对,SSB波束对中的一个波束为第一小区的SSB波束,另一个SSB波束为干扰波束;根据至少一个SSB波束对的干扰量、隔离度、以及频域起始位置总数,确定至少一个SSB波束对中的每个SSB波束对应的频域起始位置;SSB波束对的干扰量指示SSB波束对中的干扰波束对另一个SSB波束的干扰;隔离度指示两个SSB波束的频域起始位置之间的间隔。
基于该可能的设计,本申请基于SSB波束对的干扰量确定波束对应的频域资源起始位置,以波束为粒度进行频域资源起始位置的配置,从而可以为干扰较弱的不同波束配置相同的频域起始位置,减少资源浪费,并且能够预留有足够多的不同频域起始位置配置给干扰较强的波束,提升干扰控制效率。

基于该可能的设计,至少一个SSB波束对包括至少一个小区的干扰矩阵中取值最大的前M个干扰量 对应的SSB波束对时,参与计算的SSB波束对较少,可以降低对网络设备的计算能力的要求,降低网络设备的实现复杂度。至少一个SSB波束对包括至少一个小区的干扰矩阵中的全部干扰量对应的SSB波束对时,参与计算的SSB波束对较为全面,可以提高SSB波束对应的频域资源的起始位置的准确性。

基于上述可能的设计,本申请通过SSB波束的信号质量和小区的业务量,量化SSB波束间的干扰,将业务量分布纳入分析,识别干扰量较强的SSB波束对。并基于干扰量构造目标函数,将波束级频域资源起始位置的配置转换为优化问题,通过求解优化问题得到SSB波束对应的频域资源起始位置。使得网络设备可以将SSB波束对应的频域资源起始位置作为其对应的业务波束的频域资源起始位置,实现业务波束级的频域资源起始位置的配置,提高频域资源起始位置配置的自由度,从而实现精细化的频域起始位置错开,提高干扰控制效率。

为了方便理解本申请实施例的技术方案,首先给出本申请相关技术的简要介绍如下。
1、波束:
波束可以理解为一种通信资源。形成波束的技术可以是波束赋形技术或者其他技术手段。不同的波束可以认为是不同的资源。
波束在协议中具体地可以通过各种信号(或资源)的索引来表示,例如通过信道状态信息参考信号(channel state information reference signal,CSI-RS)的资源索引、同步信号块(synchronization signal block,SSB)索引,探测参考信号(sounding reference signal,SRS)的资源索引,跟踪参考信号(tracking reference signal,TRS)的资源索引等表示。
此外,波束在协议中的体现还可以是空域滤波器(spatial domain filter),或者称空间滤波器(spatial filter),或称空域参数(spatial domain parameter),空间参数(spatial parameter),空域设置(spatial domain setting),空间设置(spatial setting),或准共址(quasi Co-location,QCL)信息,QCL假设,QCL指示等。波束可以通过传输配置指示(transmission configuration indication,TCI)状态(TCI-state)参数来指示,或通过空间关系(spatial relation)参数来指示。因此,本申请中,波束也可以替换为空域滤波器,空间滤波器,空域参数,空间参数,空域设置,空间设置,QCL信息,QCL假设,QCL指示,TCI-state,或空间关系等。上述术语之间也相互等效。本申请中的波束也可以替换为其他表示波束的术语,本申请不作限定。
本申请下述实施例中,将用于发送SSB的波束称为SSB波束。示例性的,SSB波束可以通过SSB索引、QCL信息,QCL假设,QCL指示,TCI-state,或空间关系等来表示。将用于发送业务(或数据)的波束称为业务波束。
2、SSB:
通常,主同步信号(primary synchronization signal,PSS)、辅同步信号(secondary synchronization signal,SSS)、和物理广播信道(physical broadcast channel,PBCH)可以合称为SSB。
在NR系统中,网络设备可以通过波束扫描的方式发送SSB,即以时分复用的方式在不同波束上发送多个SSB。示例性的,如图1所示,网络设备可以在不同波束上发送SSB 0至SSB N。通过波束扫描发送的多个SSB可以称为同步信号(synchronization signal,SS)突发集(SS burst set)。例如,图1中的SSB0至SSB N可以称为一个同步信号突发集。
在轻载场景(例如负载不超过33%)下,采用物理小区标识(physical cell identifier,PCI)模3的频域干扰随机化方案,能够使得各个小区使用的频域起始位置错开,降低同频干扰。
示例性的,参见图2,假设图2中的立柱表示小区可使用的全部频域资源,黑色填充部分表示小区实际使用的频域资源。以小区0、小区1、和小区2为同频小区为例,如图2中的(a)所示,在未使用PCI模3的干扰随机化方案时,各个小区的频域资源均从频带的低频位置开始,从而各个小区使用的大部分频域资源重叠,小区间的同频干扰较为严重。如图2中的(b)所示,在使用PCI模3的干扰随机化方案时,可以基于PCI模3后的值,为各个小区分配不同的频域资源起始位置,使得各个小区使用的频域资源尽可能错开。在负载不超过33%的场景下,可以使得各个小区使用的频域资源完全不重叠,实现同频干扰规避。
然而,基于PCI模3的干扰随机化方案中存在如下缺陷:
一方面,一旦服务小区和邻区的PCI对3取模后的值相同,则这两个小区的频域资源起始位置相同,从而发生资源碰撞,导致干扰控制效果大打折扣。从现网的统计数据来看,频域资源起始位置冲突的比例较高,组网场景下存在30%的用户会受到PCI模3值相同的邻区信号的干扰。
另一方面,系统中可能存在PCI模3值不同的两个小区,且分别位于该两个小区的两个终端设备距离较远、业务量较小。该场景下,这两个终端设备之间不存在强干扰。但是,基于PCI模3的干扰随机化方案,将为这两个小区配置不同的频域资源起始位置,造成资源浪费,从而导致没有足够的资源分配给存在强干扰的小区,进而使得干扰控制效率较低。
再一方面,邻区间的干扰并不是存在于小区内的所有波束方向上。基于PCI模3的干扰随机化方案,为两个小区分配不同的频域资源起始位置时,相当于将位于不同小区内的所有波束的频域起始位置错开,可能造成资源浪费,导致干扰控制效率较低。
示例性的,如图3所示,假设小区A的PCI模3等于0,小区B的PCI模3等于1,小区C的PCI模3等于2。小区A中的终端设备分布在小区A的波束2、波束3、波束4的波束方向上,小区C中的终端设备分布在小区C的波束2、波束3、波束4的波束方向上。但是,小区A的波束2、波束3、波束4和小区C的波束2、波束3、波束4的波束方向是错开的,因此,小区A和小区C之间无明显干扰。但是,基于PCI模3的干扰随机化方案,将会为小区A和小区C配置不同的频域资源起始位置,使得小区A和小区C的波束的频域起始位置错开,造成资源浪费。
此外,在PCI模3的干扰随机化方案中,同一小区的不同波束使用相同的频域资源起始位置。即PCI模3的干扰随机化方案可以理解为小区级的干扰控制。
如图4所示,相比于第四代(4th generation,4G)制式,第五代(5th generation,5G)制式中业务波束的水平波宽较小,业务波束间的干扰是窄波束间的概率性干扰,因此,波束间的干扰避让存在可能性,即,5G制式支持波束级的干扰控制方案。
基于此,本申请提供一种干扰控制方案,可以实现波束级的频域起始位置配置,从而实现精细化的频域起始位置错开,提高干扰控制效率,进而降低干扰,提升用户体验。进一步的,由于可以实现精细化的频域起始位置配置,从而可以为无明显干扰的波束配置相同的频域起始位置,避免资源浪费。
本申请提供的技术方案可用于各种通信系统,该通信系统可以为第三代合作伙伴计划(3rd generation partnership project,3GPP)通信系统,例如,4G长期演进(long term evolution,LTE)系统、演进的LTE系统(LTE-Advanced,LTE-A)系统、5GNR系统、车联网(vehicle to everything,V2X)系统、LTE和NR混合组网的系统、或者设备到设备(device-to-device,D2D)系统、机器到机器(machine to machine,M2M)通信系统、物联网(internet of things,IoT),以及其他下一代通信系统等。或者,该通信系统也可以为非3GPP通信系统,不予限制。
其中,上述适用本申请的通信系统仅是举例说明,适用本申请的通信系统不限于此,在此统一说明,以下不再赘述。

可选的,CU和DU可以根据无线网络的协议层划分:比如,分组数据汇聚层协议(packet data convergence protocol,PDCP)层及以上协议层(例如无线资源控制(radio resource control,RRC)层和业务数据适配协议(service data adaptation protocol,SDAP)层等)的功能设置在CU,PDCP层以下协议层(例如无线链路控制(radio link control,RLC)层、媒体接入控制(media access control,MAC)层、或物理(physical,PHY)层等)的功能设置在DU;又比如,PDCP层以上协议层的功能设置在CU,PDCP层及以下协议层的功能设置在DU,不予限制。
上述对CU和DU的处理功能按照协议层的划分仅仅是一种举例,也可以按照其他的方式进行划分。例如,可以将CU或者DU划分为具有更多协议层的功能,又例如将CU或DU划分为具有协议层的部分处理功能。例如,将RLC层的部分功能和RLC层以上的协议层的功能设置在CU,将RLC层的剩余功能和RLC层以下的协议层的功能设置在DU。再例如,可以按照业务类型或者其他系统需求对CU或者DU的功能进行划分,例如按时延划分,将处理时间需要满足时延要求的功能设置在DU,不需要满足该时延要求的功能设置在CU。
可选的,本申请实施例中的基站可以包括各种形式的基站,例如:宏基站、微基站(也称为小站)、中继站、接入点、家庭基站、TRP、发射点(transmitting point,TP)、移动交换中心等,本申请实施例对此不作具体限定。

下面将结合附图,对本申请实施例提供的方法进行展开说明。可以理解的,本申请实施例中,网络设备或终端设备可以执行本申请实施例中的部分或全部步骤,这些步骤或操作仅是示例,本申请实施例还可以执行其它操作或者各种操作的变形。此外,各个步骤可以按照本申请实施例呈现的不同的顺序来执行,并且有可能并非要执行本申请实施例中的全部操作。
如图6所示,为本申请提供的一种干扰控制方法,该干扰控制方法包括如下步骤:
S601、网络设备获取第一小区的多个SSB波束对应的频域资源起始位置。
其中,至少两个SSB波束对应的频域资源起始位置不同。示例性的,若整个频带中的频域资源起始位置的总数为N,则该多个SSB波束中可以存在N个SSB波束对应的频域资源起始位置互不相同。
可选的,本申请实施例中的频域资源可以通过资源元素(resource element,RE)或资源块(resource block,RB)表示。SSB波束对应的频域资源起始位置可以通过RE索引或RB索引表示。
可选的,该多个SSB波束可以是第一小区的全部SSB波束,或者,可以是第一小区的部分SSB波束,本申请对此不作具体限定。
可选的,网络设备可以通过波束扫描的方式发送SSB波束。即,该多个SSB波束中不同SSB波束的方向不同。
可选的,网络设备获取第一小区的多个SSB波束对应的频域资源起始位置,可以包括:网络设备自主确定第一小区的多个SSB波束对应的频域资源起始位置;或者,网络设备接收来自其他设备或平台的第一小区的多个SSB波束对应的频域资源起始位置,将在后续实施例中说明,在此不予赘述。
S602、网络设备确定第一业务波束。第一业务波束为第一终端设备对应的业务波束。
其中,第一终端设备为第一小区中的终端设备。或者说,第一小区为第一终端设备的服务小区。
可选的,第一终端设备对应第一业务波束,可以理解为:第一终端设备处于该第一业务波束的覆盖范围内,或者说,第一终端设备处于该第一业务波束的方向上。
其中,第一业务波束关联第一小区的多个SSB波束中的第一SSB波束。示例性的,第一业务波束的水平方向和第一SSB波束的水平方向相同;或者,第一业务波束的水平方向和第一SSB波束的水平方向的差值小于阈值。
可选的,第一小区的多个SSB波束中的每个SSB波束可以关联至少一个业务波束。对于该多个SSB波束中的任一SSB波束(称为第二SSB波束)来说,第二SSB波束的水平方向和第二SSB波束关联的业务波束的水平方向相同;或者,第二SSB波束的水平方向和第二SSB波束关联的业务波束的水平方向的差值小于阈值。该阈值可以是协议定义的,或者,可以是网络设备确定的,本申请对此不作具体限定。
示例性的,以第一小区的SSB波束的数量为8,网络设备为64收发通道的海量(massive)多输入多输出(multiple input multiple output,MIMO)设备(即64TRxMM设备)为例,网络设备可以将32个业务波束划分至8个水平方向和4个垂直方向上。不考虑垂直方向差异的情况下,如图7所示,参见上半部分的90°到-90°,7个SSB波束的水平方向和32个业务波束的7个水平方向基本重合;32个业务波束的另一个水平方向可以由另一SSB波束的水平方向(图7中未示出)得到。
可选的,网络设备在第一小区的多个SSB波束关联的多个业务波束上测量来自第一终端设备的探测参考信号(sounding reference signal,SRS)的信号质量。之后,将该多个业务波束中,SRS的信号质量最强的业务波束确定为第一业务波束。基于该步骤,网络设备可以认为第一终端设备位于该第一业务波束的覆盖范围内,或者说,认为第一终端设备处于该第一业务波束的方向上。
S603、网络设备通过第一业务波束在第一频域资源上为第一终端设备提供服务。其中,第一频域资源的起始位置为第一SSB波束对应的频域资源起始位置。
可选的,网络设备通过第一业务波束在第一频域资源上为第一终端设备提供服务,可以包括:网络设备通过第一业务波束在第一频域资源上向第一终端设备发送下行信号,和/或,接收来自第一终端设备的上行信号。
基于该方案,网络设备可以确定SSB波束级的频域资源起始位置,将SSB波束对应的频域资源起始位置作为其对应的业务波束的频域资源起始位置,通过该业务波束在该频域资源起始位置上为终端设备提供服务。也就是说,网络设备可以通过SSB波束对应的频域资源起始位置指导业务波束的频域资源起始位置的配置,实现业务波束的波束级频域资源起始位置的配置,从而实现精细化的频域起始位置错开,提高干扰控制效率,进而降低干扰,提升用户体验。
此外,本申请以波束为粒度配置频域资源起始位置,从而可以为业务量较小、干扰较弱的不同波束配置相同的频域起始位置,减少资源浪费,并且能够预留有足够多的不同频域起始位置配置给干扰较强的波束,提升干扰控制效率。
以上对本申请提供的干扰控制方案的流程进行了整体说明。下面对上述各个步骤的详细实现进行介绍。
可选的,以网络设备自主确定第一小区的多个SSB波束对应的频域资源起始位置为例,如图8所示,上述步骤S601可以通过下述步骤S6011和S6012实现。该步骤S6011和S6012包括:
S6011、网络设备确定至少一个SSB波束对。
其中,SSB波束对由两个SSB波束构成。该至少一个SSB波束对包括第一小区对应的SSB波束对。第一小区对应的SSB波束对中的一个波束为第一小区的SSB波束,另一个SSB波束为干扰波束。该干扰波束为第一小区的邻区的SSB波束。示例性的,干扰波束可以理解为对终端设备的服务小区的波束造成干扰的波束。
可选的,网络设备可以确定至少一个小区的干扰矩阵,并根据该至少一个小区的干扰矩阵确定至少一个SSB波束对。
可选的,该至少一个小区中的任一小区(记为小区A)的干扰矩阵包括小区A的各个SSB波束和小区B的各个SSB波束构成的SSB波束对的干扰量。其中,SSB波束对的干扰量指示SSB波束对中的干扰波束对另一个SSB波束的干扰(或干扰概率)。小区B可以包括该至少一个小区中除小区A之外的部分或全部小区。此时,小区B的SSB波束作为SSB波束对中的干扰波束。
可选的,该至少一个小区可以包括第一小区,第一小区的干扰矩阵即包括第一小区的多个SSB波束和第二小区的各个SSB波束构成的SSB波束对的干扰量。第二小区包括该至少一个小区中除第一小区之外的部分或全部小区。第二小区的SSB波束作为SSB波束对中的干扰波束。
示例性的,以第一小区的SSB波束的数量为8,第一小区的某个邻区的SSB波束的数量同样为8为 例,第一小区的干扰矩阵可以表示为如下表1的形式:
表1
其中,SSB波束Ax表示第一小区的SSB波束;SSB波束Bx表示第一小区的某个邻区的SSB波束。如表1所示,SSB波束A0和SSB波束B0对应的8.7%表示邻区的SSB波束0对第一小区的SSB波束0的干扰量为8.7%。
上述仅以第一小区的一个邻区为例对第一小区的干扰矩阵进行了说明。在第一小区的邻区包括多个小区时,第一小区的干扰矩阵需要在表1的基础上增加X列,每一列对应第一小区的其他邻区的一个SSB波束。
上述以第一小区的干扰矩阵为例进行说明。其他小区的干扰矩阵的结构类似于第一小区的干扰矩阵,可参考第一小区的干扰矩阵的相关说明,在此不再赘述。
可选的,上述至少一个小区可以为同一网络设备管理的小区。或者,该至少一个小区中可以包括多个网络设备管理的小区。该场景下,各个网络设备可以确定其管理的小区的干扰矩阵,并向执行本申请实施例方案的网络设备发送其确定的干扰矩阵。
作为一种可能的实现,确定至少一个小区的干扰矩阵后,网络设备可以确定上述至少一个SSB波束对包括该至少一个小区的干扰矩阵中取值最大的前M个干扰量对应的SSB波束对,M为正整数。
示例性的,以至少一个小区的干扰矩阵为第一小区的干扰矩阵为例,假设M等于6,则至少一个SSB波束对包括取值最大的前6个干扰量对应的SSB波束对。基于表1所示的示例,取值最大的前6个干扰量为18.6%、18.4%、13.4%、8.7%、6.5%、5.0%,对应的SSB波束对分别为:{SSB波束A7,SSB波束B6}、{SSB波束A7,SSB波束B0}、{SSB波束A7,SSB波束B3}、{SSB波束A0,SSB波束B0}、{SSB波束A7,SSB波束B5}、{SSB波束A5,SSB波束B7}。作为另一种可能的实现,确定至少一个小区的干扰矩阵后,网络设备可以确定上述至少一个SSB波束对包括该至少一个小区的干扰矩阵中的全部干扰量对应的SSB波束对。
示例性的,以至少一个小区的干扰矩阵为第一小区的干扰矩阵为例,基于表1所示的示例,上述至少一个SSB波束对即包括表1所示的全部(共64个)SSB波束对。
S6012、网络设备根据至少一个SSB波束对的干扰量、隔离度、以及频域起始位置总数,确定至少一个SSB波束对中的每个SSB波束对应的频域起始位置。
其中,SSB波束对的干扰量指示SSB波束对中的干扰波束对另一个SSB波束的干扰(或干扰概率)。隔离度指示两个SSB波束的频域起始位置之间的间隔。频域起始位置总数可以是协议定义的,或者可以是网络设备确定的,本申请对此不作具体限定。
可选的,SSB波束对的干扰量由该SSB波束对中的两个SSB波束的信号质量、两个SSB波束所属小区的业务量确定。例如,第一小区对应的SSB波束对的干扰量由以下参数确定:第一小区的SSB波束的 信号质量、该SSB波束对中干扰波束(第一小区的邻区的SSB波束)的信号质量、第一小区的业务量、干扰波束所属小区(记为第二小区)的业务量。
可选的,SSB波束的信号质量可以通过参考信号接收功率(reference signal receiving power,RSRP)、参考信号接收质量(reference signal received quality,RSRQ)等表示,本申请对此不作具体限定。此外,SSB波束的信号质量也可以称为SSB波束的电平,二者可以相互替换。
示例性的,某个服务小区对应的SSB波束对的干扰量可以满足:
服务小区对应的SSB波束对的干扰量=(服务小区的SSB波束的信号质量-邻区的干扰波束的信号质量)*(服务小区的业务量+邻区的业务量)。
也就是说,第一小区作为服务小区时,第一小区对应的SSB波束对的干扰量可以满足:
第一小区对应的SSB波束对的干扰量=(第一小区的SSB波束的信号质量-干扰波束的信号质量)*(第一小区的业务量+第二小区的业务量)。
可选的,SSB波束的信号质量和小区的业务量可以是终端设备上报的。示例性的,第一终端设备可以向网络设备发送测量报告(measurement report,MR)。相应的,网络设备可以接收来自第一终端设备的测量报告。来自第一终端设备的该测量报告可以指示第一小区的SSB波束的信号质量、干扰波束(即第二小区的SSB波束)的信号质量、或第一小区的业务量中的至少一个。
可选的,位于第二小区内的第二终端设备(即第二终端设备的服务小区为第二小区)也可以向网络设备发送测量报告。相应的,网络设备可以接收来自第二终端设备的测量报告。来自第二终端设备的该测量报告可以指示第二小区的业务量。进一步的,来自第二终端设备的测量报告还可以指示第二小区的SSB波束的信号质量、第二小区的邻区的SSB波束(对于第二小区来说为干扰波束)的信号质量等用于确定第二小区的干扰矩阵的信息。
可选的,网络设备可以求解优化问题得到指示一个SSB波束对中的每个SSB波束对应的频域起始位置。该优化问题可以基于约束条件和最小化目标函数得到。
其中,目标函数由至少一个SSB波束对的干扰量、频域起始位置总数、以及变量确定。隔离度为该变量在优化问题中的解。
作为一种可能的实现方式,该优化问题为:
min∑mn(Interferencemn*(N-Isolationmn))subject to Isolationmn∈[0,N-1]
其中,Interferencemn为SSB波束m和SSB波束n构成的SSB波束对的干扰量。N为频域起始位置总数。Isolationmn为隔离度,Isolationmn=|Posm-Posn|;Posm为SSB波束m对应的频域起始位置的索引,Posn为SSB波束n对应的频域起始位置的索引。Isolationmn∈[0,N-1]为约束条件。
mn表示对上述至少一个SSB波束对中的每个SSB波束对的(Interferencemn*(N-Isolationmn))进行求和。
作为另一种可能的实现方式,该优化问题为:
min∑mn(Interferencemn*(N-Isolationmn)*SameSiteFlagmn)subject to Isolationmn
[0,N-1]
其中,SameSiteFlagmn用于表示SSB波束m和SSB波束n是否属于同一小区,若SSB波束m和SSB波束n属于同一小区,SameSiteFlagmn=0,若SSB波束m和SSB波束n不属于同一小区,SameSiteFlagmn=1。
可选的,(N-Isolationmn)可以称为干扰量影响因子或干扰量权重。隔离度越小,两个SSB波束对应的频域起始位置越近,(N-Isolationmn)的值越大,其对干扰量的影响越大;隔离度越大,两个SSB波束对应的频域起始位置越远,(N-Isolationmn)的值越小,干扰控制效果越好。此外,上述优化问题可以对所有SSB波束对的干扰量及其影响因子的乘积求和后寻找较优解,即综合考虑了网络中多个小区的多个SSB波束之间的干扰,从整网角度进行干扰控制,从而降低整网的干扰水平。
可选的,上述步骤S6011和S6012中的至少一个小区可以是优化区域(或称为干扰控制区域)中的部分小区。网络设备可以预先确定优化区域,从优化区域中选择部分小区执行上述步骤S6011和S6012,得到该部分小区中各个小区的各个SSB波束对应的频域资源起始位置。之后,可以选择优化区域中的其他小区执行上述步骤S6011和S6012,直至确定出优化区域中全部小区的SSB波束对应的频域资源起始位置。
基于此,可以将优化区域划分为多个较小的区域,以小区域为粒度分别确定各个小区域中各小区的SSB波束对应的频域资源起始位置。相比于一次性对整个优化区域内的全部小区的SSB波束对应的频域 资源起始位置进行求解的方案,可以降低对计算能力的要求,提高优化效率。
上述以网络设备确定各个小区的SSB波束对应的频域资源起始位置为例进行说明。此外,各个小区的SSB波束对应的频域资源起始位置也可以由其他电子设备或平台确定。该平台例如可以为移动宽带(mobile broadband,MBB)自动化引擎(MBB auto engine,MEA)平台确定。即,MAE平台可以执行上述步骤S601(包括S6011和S6012)中由网络设备执行的,用于确定SSB波束对应的频域资源起始位置的步骤或功能。
示例性的,MAE平台可以从各个网络设备中获取终端设备上报的测量报告,从而获取SSB波束的信号质量、各个小区的业务量,确定各个小区的干扰矩阵,并求解优化问题得到SSB波束对应的频域资源起始位置。
可选的,确定SSB波束对应的频域资源起始位置后,MAE平台可以向网络设备发送各个网络设备管理的各个小区的SSB波束对应的频域资源起始位置,以使网络设备执行后续处理,例如执行上述步骤S602和S603。
基于上述方案,本申请实施例通过SSB波束的信号质量和小区的业务量,量化SSB波束间的干扰,将业务量分布纳入分析,识别干扰量较强的SSB波束对。并基于干扰量构造目标函数,将波束级频域资源起始位置的配置转换为优化问题,通过求解优化问题得到SSB波束对应的频域资源起始位置。使得网络设备可以将SSB波束对应的频域资源起始位置作为其对应的业务波束的频域资源起始位置,实现业务波束级的频域资源起始位置的配置,提高频域资源起始位置配置的自由度,从而实现精细化的频域起始位置错开,提高干扰控制效率。
下面以具体示例对基于PCI模3的方案和申请的方案进行对比说明。示例性的,如图9所示,假设网络中的网络设备1管理小区0、小区1、和小区2,网络设备2管理小区3。通常同一网络设备管理的小区的PCI是连续的,PCI对3取模的值不同,因此,基于PCI模3的方案,网络设备1管理的3个小区的频域起始位置可以不同。但是,如果网络设备2管理的小区3与小区0的PCI对2取模的值相同,那么如图9所示,小区3和小区0的频域起始位置相同,导致两个小区之间存在强干扰,干扰避让效果大幅恶化。即,采用PCI模3的方案时,在PCI规划分配不合理,或者网络设备密集部署邻区较多的场景下,干扰避让效果较差。
基于本申请实施例提供的方案,如图10所示,以频域资源起始位置的总数等于6为例,假设网络中的网络设备1管理小区0、小区1、和小区2,网络设备2管理小区3,网络设备可以以波束为粒度配置频域资源起始位置。并且,通过对干扰的量化,可以识别干扰较强的波束对,为强干扰波束对配置不同的频域资源起始位置。例如,同一网络设备管理的不同小区的边缘波束间(波束0和波束7)、不同网络设备管理的不同小区的对打波束间的干扰可能较强,基于本申请的方案,可以为边缘波束和对打波束分配不同的频域资源起始位置,剩余的频域资源起始位置可以分配给其他波束,从而降低整网干扰。
相比于PCI模3的方案,本申请引入波束级频域资源起始位置配置的自由度,在邻区数量较多,PCI规划不合理等场景下,仍然有充足的频域资源起始位置配置的自由度来精细化地为干扰波束分配不同的频域资源起始位置,从而降低整网干扰,提升用户体验。

本申请实施例可以根据上述方法实施例对通信装置进行功能模块的划分,例如,可以对应各个功能划分各个功能模块,也可以将两个或两个以上的功能集成在一个处理模块中。上述集成的模块既可以采用硬件的形式实现,也可以采用软件功能模块的形式实现。需要说明的是,本申请实施例中对模块的划分是示意性的,仅仅为一种逻辑功能划分,实际实现时可以有另外的划分方式。
