为了便于理解,以下将对本申请实施例所涉及的基本概念作简单介绍。
波束赋形是调整波束指向的一项关键技术方案,主要利用波的干涉原理,通过改变每个天线振元上的信号幅度及相位参数,使发射波的主瓣对准目标终端设备的方向,而使零点和副瓣对准其他非期望用户,从而增强目标终端设备的接收信号,同时降低用户间的干扰,最终提升***容量。此外天线辐射的方向可以通过改变波源之间的相对延时来实现,实时跟踪发射端和接收端之间相对位置的改变。
上述天线阵元指的是构成天线阵的天线辐射单元,将工作在同一频率的两个或两个以上的单个天线,按照一定的要求进行馈电和空间排列构成天线阵列,也叫天线阵。天线阵列可以是单频或多频,可以是单极化天线,也可以是多极化天线,本申请实施例对此不作限定。
波束赋形包括数字波束赋形(digital beamforming,DBF)和模拟波束赋形(analog beamforming,ABF)。DBF可以提供更精确的波束赋形,但是要求每个天线端口拥有独立的基带处理模块和高功耗模-数/数-模(analog-digital/digital-analog,AD/DA)转换模块,这导致硬件结构的复杂度、成本和功耗等都较高;ABF相比DBF更简单、成本更低,但是赋形灵活性较低,损失了***性能。为了综合两种赋形方式的优缺点,将ABF和DBF结合起来,即将射频端的幅度相位可调的波束赋形与基带的数字波束赋形相结合,称之为混合波束赋形(hybrid beamforming,HBF)。HBF把传统MIMO***中的全DBF拆分为基带端的DBF和射频端的ABF,即首先通过基带端的DBF矩阵把不同的数据流映射到相应的射频链路上,然后利用射频端的ABF矩阵把不同射频链路上的数据流映射到不同的天线阵元。
本申请实施例网络设备会随终端设备位置、信道状态等动态变化因素调整波形宽度和方向,形成对准终端设备的窄波束。指向终端设备的动态波束是通过赋予阵元不同的波束权值来获得。其中,波束权值是指基于下行信道特征计算出的向量,用于改变波束形状和方向。
下面将结合附图,对本申请实施例中的技术方案进行描述。
图1是本申请的通信***的示意性架构图。如图1所示,该通信***包括:天线、馈线、抱杆、光纤、射频拉远单元(remote radio unit,RRU)、基带单元(base band unit,BBU)等,其中天线包括控制驱动模块,天线与RRU通过馈线连接,RRU与BBU之间通过光纤连接。
图2示出了本申请的实施例应用的基于数字移相器控制模拟权值的HBF天线***,该***包括BBU、RRU和天线。HBF天线***的波束权值一般分为两种:基带权值和模拟权值。现有技术对于HBF天线***的权值处理方法是:网络设备基于下行信道特征计算动态波束权值,其中基带权值由BBU下发基带信号给RRU,RRU对信号进行处理后映射到天线端口;模拟权值是通过RRU下发控制命令给天线控制驱动模块,其中的控制模块通过驱动模块控制数字移相器输出不同模拟的权值(如图2中虚线框内所示)。最终权 值由基带权值和模拟权值经过加权处理后得到,由辐射单元形成指向目标终端设备的窄波束。现有技术在计算波束权值时仅基于下行信道特征,对于下行信道特征估计时无法获取的但影响用户体验或网络性能的信息并没有考虑在内,因此现有技术中波束权值的准确性仍然无法满足NR业务或网络的需求。应理解,图2中的省略号代表多个,本申请对其中射频信号线路和辐射单元的数量并不作任何限定。
此外,天线内部包括天线接头、控制接头、控制驱动模块、射频馈电网络和辐射单元等。其中,天线位于天线罩中,辐射单元和反射板集合成至少一个独立阵列,辐射单元的频率可以相同或者不同,辐射单元通常放置于反射板上方。天线阵列通过各自的馈电网络接收或发射射频信号。天线控制驱动模块(含开关控制模块和驱动模块)用于接收来自网络设备的控制命令并执行,通过驱动模块控制天线数字移相器上的可调微波开关,改变波束权值。控制模块上有处理器(central processing unit,CPU),可以实现与网络设备的通信,并通过驱动模块实现对微波开关的控制。馈电网络可能包含移相网络,还可能存在合路器、滤波器、功分器等用于扩展性能的模块。馈电网络可以通过控制驱动模块控制数字移相器实现不同模拟权值。
应理解,图2仅是能应用本申请实施例所提供方法的***的一种示例,对于其他可运用此方法的***,图2并不作任何限定。
可以理解的是,本申请实施例提及的天线可以是传统的网络设备天线,也可以是毫米波天线,还可以安装在带有多天线的WIFI路由器中,或者安装到手机上等,本申请实施例对天线的数量、形式、内部结构及安装位置并不作任何限定,图1和图2仅为一种示例。
为了满足新业务需求,本申请实施例提供了一种无线通信方法,在根据下行信道特征确定模拟权值的基础上,进一步获取下行信道特征估计时无法获取但影响用户体验或网络性能的信息以提高动态波束权值的准确性。
作为示例而非限定,本申请实施例所涉及的下行信道特征估计时网络设备可获取的信息包括信道测量和干扰测量,例如信号与干扰加噪声比(signal to interference plus noise ratio,SINR)和参考信号接收功率(reference signal receiving power,RSRP),其中SINR指的是信号接收端接收到的有用信号的强度与接收到的干扰信号(噪声和干扰)的强度的比值,RSRP指的是某个符号内承载参考信号的所有资源单元(resource element,RE)上接收到的信号功率的平均值。
有两种不同的获取下行信道特征的方法:一种是网络设备通过测量终端设备上行信道的信道探测参考信号(sounding reference signal,SRS),根据互易原理计算出对应下行信道的特征;另一种是指终端设备测量下行信道状态信息-参考信号(channel state information-reference signal,CSI-RS),将测量结果通过预编码矩阵指示(pre-coding matrix indication,PMI)上报给网络设备,网络设备基于PMI估计出下行信道特征。
作为示例而非限定,本申请实施例所涉及的下行信道特征估计时无法获取但影响用户体验或网络性能的信息(即,天线预设参数)包括无源互调(passive inter modulation,PIM)参数、信号传播时延参数、零填参数、***损耗参数、器件功耗参数等。这些参数预设在天线出厂参数中,针对不同的模拟权值可以预先测量或估计并写入出厂参数表格中。模拟权值与这些天线预设参数对应,不同的模拟权值是通过数字移相器上可调微波开关不同的状态获得的,数字移相器不同的状态对应上述不同的天线预设参数。由于这些天线预设参 数无法获得,因此一定程度上影响了用户体验或网络性能,例如用户在游戏过程中,会出现画面卡顿等现象,用户的游戏体验差,信号传播时延参数是影响用户游戏时延体验的一个重要参数。
以下,对一些天线预设参数进行介绍:
PIM,由通信和电子***中各种无源器件的非线性特性引起。在大功率、多信道***中,这些无源器件的非线性会产生相对于工作频率的更高次谐波,而这些谐波又会和工作频率混合产生一组新的频率组合,其最终结果会产生一组无用的频谱成份而影响通信***的正常工作。
信号传播时延,指电磁信号在传输介质中传播一定的距离所花费的时间,即从发送端发送数据开始,到接收端收到数据(或者从接收端发送确认帧,到发送端收到确认帧)总共经历的时间。
***损耗,指当信号通过一个模块(主要是无源模块,包括电缆、接头、滤波器、混频器等)后电平的衰减量。
器件功耗,器件功率的损耗,指器件输入功率和输出功率的差额。电路中通常指元器件上耗散的热能。数字移相器的开关电路上,开关不同状态对应不同的功耗。
作为示例而非限定,本申请实施例所涉及的模拟权值表如表一所示。天线内部存储单元存储了所有天线内数字移相器可以输出的模拟权值。网络设备基于下行信道特征计算动态波束权值,通过RRU下发控制命令给天线控制驱动模块,其中的控制模块通过驱动模块控制数字移相器输出不同模拟的权值。在这个过程中,本申请实施例基于历史数据,将所有可由天线控制驱动模块输出的模拟权值存储入天线的存储单元中。换句话说,由网络设备通过RRU下发的模拟权值与天线存储表中的多个模拟权值至少有一个相同。
每个模拟权值都对应一个波束、一组下行信道特征估计时可获取的信息和一组天线预设参数。同时,每个波束都有其固定的形状,模拟权值1-模拟权值12对应波束1-波束12。根据不同模拟权值对应天线辐射方向图波形的相似度对波束1-波束12进行分类。相似度可以理解为波束形状的相似程度或者是波束形状的重合度。
例如,图3示出了两个波束的波形图,周向坐标表示空间角度,径向坐标表示增益,图中波束1和波束2基本重合,仅有部分角度下增益较小的地方存在细微差别,可认为满足相似度的要求,即波束1和波束2互为相似波束或同一类型的波束。本申请实施例对相似程度或者重合度的具体数值不作限定,本领域技术人员可根据实际情况灵活设定,例如可规定波形图中不同波形增益的差值维持在一定范围内。
在此情况下,模拟权值1-模拟权值12也随之进行了分类,分类结果如表一,同一候选权值集合的每两个模拟权值对应的SINR和RSRP的差值在预设的范围内,该范围与波形相似度相关。换句话说,当认为两个波束相似时,其模拟权值对应的SINR和RSRP的差值是在一定范围内的。
作为一种实现方式,在表1中,A表示天线预设参数中的PIM参数、B表示天线预设参数中的传播时延参数、C表示天线预设参数中的器件功耗参数,a1-a12是A对应的值,b1-b12是B对应的值,c1-c12是C对应的值。
可以理解的是,模拟权值的个数大于等于模拟权值集合的个数。
应理解,表一仅是辅助理解本申请技术方案的示例,本申请实施例对表一字母所代表 的含义,参数的数量并不作任何限定。

应理解,不同业务对天线预设参数的种类和数量的需求可能不同,本申请实施例对此并不作任何限定。为了进一步阐述本申请的技术方案,以下将以业务需求与天线预设参数的其中两种参数相关为例进行说明。
图6是本申请实施例的无线通信过程的另一例示意***互图。在一种可能的实现方式中,如图6所示,以NR业务#B为例,以模拟权值表是表一为例,以下行信道特征估计时获取的信息是SINR和RSRP为例,业务#B要求对传播时延参数和器件功耗参数(即,目标天线预设参数的其中两例)进行优化。该方法包括如下步骤:
步骤301~步骤303与步骤101~步骤103类似,此处不再赘述;
步骤304:天线控制驱动模块在确定到的候选权值集合#1中选择传播时延和器件功耗
小于等于第一模拟权值对应的传播时延和器件功耗的模拟权值,若该模拟权值有一个,则确定该模拟权值为第二模拟权值;若该模拟权值有多个,则根据传播时延参数和器件功耗参数的优先级选择第二模拟权值,优先级可预先设定,与天线预设参数一起写在表中,也可以根据网络设备反馈的不同业务的最高诉求来确定,此处不做限定。
根据传播时延参数和器件功耗参数的优先级选择第二模拟权值,可分为以下两种情况:
情况1:传播时延参数的优先级高于器件功耗参数要求的优先级。
在上述满足条件的多个模拟权值中优先选择传播时延最小时对应的模拟权值,并确定该模拟权值为第二模拟权值。
情况2:器件功耗参数的优先级高于传播时延参数的优先级。
在上述满足条件的多个模拟权值中优先选择器件功耗最小时对应的模拟权值,并确定该模拟权值为第二模拟权值。

步骤404,天线控制驱动模块根据传播时延参数和器件功耗参数以及传播时延参数和器件功耗参数的权重在确定到的候选权值集合#2中选择第二模拟权值;
具体为,假设由网络设备的基带单元计算的第一模拟权值为候选权值集合#2中的模拟权值6,则其对应的传播时延参数值为b6,器件功耗参数为c6;设定传播时延参数的权重为k,器件功耗参数的权重为h。以候选权值集合#2中的模拟权值5为例,其对应的传播时延参数值为b5,器件功耗参数为c5,计算(b6-b5)×k+(c6-c5)×h的值,候选权值集合#2中的其他模拟权值也依次与模拟权值6进行相同的计算(即,将式中的b5和c5替换为b6、b7、b8和c6、c7、c8),比较所有候选权值的计算结果,获得计算结果大于等于零时对应的模拟权值。若满足该条件的权值有一个,则确定该模拟权值为第二模拟权值;若满足该条件的权值有多个,则选择计算结果最大时对应的模拟权值为第二模拟权值。
例如,假设第一模拟权值对应的传播时延与器件功耗分别为5ms和5w,某一个候选权值对应的传播时延与器件功耗分别为3ms和6w,设定传播时延参数的权重为70%,器件功耗的参数的权重为30%,则可计算(5-3)×70%+(5-6)×30%=1.1,该值大于等于0,则可以确定该候选权值为第二模拟权值。
步骤405,天线控制驱动模块控制数字移相器输出第二模拟权值,第二模拟权值结合基带权值经加权处理后形成波束权值,该波束权值与终端设备通信时使用的波束对应。
应理解,上述方案仅为示例而非限定,无论是根据优先级排序或者设定不同权重进行比较,或者两种方法的结合选出第二模拟权值,亦或是未来出现的其他比较方法,都在本申请的保护范围内。
应理解,在本申请实施例中,根据单一参数做出波束选择,还是根据多参数按优先级次序或者权重做出第二模拟权值的选择,可以预先设定,与天线预设参数一起写在表中,也可以根据网络设备反馈业务场景的具体诉求来确定,此处不做限定。
需要注意的是,本申请实施例中提及的“最小”、“小于”字样,仅针对本申请实施例中所列举的场景,不排除在其他场景中需求“最大”、“大于”等,此类字眼并不构成对本申请技术方案的限定。还应理解,为了满足业务需求,本领域技术人员可根据本申请实施例提供的方法灵活指定天线预设参数的比较规则,从而据此确定模拟权值。

例如,在该步骤中,若第一模拟权值对应的传播时延参数的值为5ms,假设b1>5ms,b2<5ms,和b4<5ms,则第二可以是候选权值集合#1中传播时延参数B=b2对应的模拟权值2或B=b4对应的模拟权值4;
