Abstract
本申请实施例提供了一种波束生成方法及其相关装置,用于提升接入网设备与终端设备之间的通信性能。本申请实施例的波束生成方法包括:终端设备接收接入网设备发送的M个参考信号资源;所述终端设备分别测量所述M个参考信号资源,得到第一测量信息,所述第一测量信息包括第一相位信息,所述第一相位信息为所述终端设备分别测量所述M个参考信号资源中的N个参考信号资源得到的相位信息,所述N和所述M均为大于或等于1的整数,所述M大于或等于所述N;所述终端设备向所述接入网设备发送第一指示信息,所述第一指示信息用于指示所述第一相位信息。
Description
本申请涉及通信技术领域,尤其涉及一种波束生成方法以及相关装置。
在高频通信系统中,为了克服路径损耗,基站和终端设备之间通常都会使用高增益的天线阵列形成具有方向的模拟波束进行通信。只有当基站的发送波束的方向与终端设备的接收波束的方向对齐时,基站与终端设备之间才能实现正常通信。
目前,基站选择发送波束的主要方式为:基站生成多个固定权值模拟发送波束,然后基站通过该多个固定权值模拟发送波束并在多个固定权值模拟发送波束对应的参考信号资源上向终端设备分别发送该参考信号资源对应的参考信号,并由该终端设备测量该参考信号。然后,终端设备向基站上报该参考信号的测量信息(包括该参考信号的参考信号接收功率(reference signal receiving power,RSRP)、参考信号接收质量(Reference signal receiving quality,RSRQ)等),再由基站根据该测量信息从该多个固定权值模拟发送波束选择一个固定权值模拟发送波束作为该基站的发送波束。
但是,该多个固定权值模拟发送波束的主瓣方向是不连续的,因此两个固定权值模拟发送波束之间会出现凹坑。凹坑的深度与该固定权值模拟发送波束生成参数相关。例如,该固定权值模拟发送波束的总数、波束宽度、波束增益等。由于终端设备的移动性,所以基站与终端设备之间的相位位置是变化的。若终端设备处于该两个固定权值模拟发送波束之间的凹坑处,基站从该两个固定权值模拟发送波束选择任意一个固定权值模拟发送波束作为基站的发送波束都会损失基站的波束增益,导致基站与终端设备之间的通信性能降低。
发明内容
本申请提供了一种波束生成方法及其相关装置,用于提升接入网设备与终端设备之间的通信性能。
本申请第一方面提供一种通信方法,该通信方法包括:
终端设备接收接入网设备发送的M个参考信号资源;然后,该终端设备分别测量该M个参考信号资源,得到第一测量信息,该第一测量信息包括第一相位信息,该第一相位信息为该终端设备分别测量该M个参考信号资源中的N个参考信号资源得到的相位信息,N和M均为大于或等于1的整数,M大于或等于N;该终端设备向该接入网设备发送第一指示信息,该第一指示信息用于指示该第一相位信息。
上述方案中,终端设备测量该N个参考信号资源的第一相位信息,并向接入网设备发送第一指示信息,以指示该第一相位信息。在终端设备的移动过程中,接入网设备与终端设备之间的信道条件是不停变化的,而N个参考信号资源分别对应的N个发送波束。因此,N个参考信号资源的第一相位信息可以体征该接入网设备与终端设备的信道变化情况,这样接入网设备可以结合第一相位信息生成匹配终端设备与接入网设备之间的信道条件的新的 发送波束,或者,从该接入网设备的N个发送波束中选择匹配匹配终端设备与接入网设备之间的信道条件的发送波束,以提升接入网设备与终端设备之间的通信性能。
一种可能的实现方式中,该M个参考信号资源用于波束管理,该第一相位信息用于该接入网设备生成第一发送波束,该第一发送波束用于该接入网设备与该终端设备之间进行通信。
在该可能的实现方式中,在波束管理过程中,终端设备新增上报第一相位信息,这样接入网设备可以结合该第一相位信息生成符合终端设备与接入网设备的信道条件的第一发送波束;然后,该接入网设备通过该第一发送波束与该终端设备进行通信,从而提高终端设备与接入网设备之间的传输性能。
另一种可能的实现方式中,该第一发送波束不属于发送波束集合,该发送波束集合包括该接入网设备生成的与该M个参考信号资源分别对应的发送波束。
在该可能的实现方式中,该第一发送波束不属于该接入网设备生成的M个发送波束中的发送波束,该M个发送波束为该接入网设备生成的固定权值的发送波束。第一发送波束的主瓣方向对准该终端设备,那么接入网设备与该终端设备通过第一发送波束进行通信传输,第一发送波束的波束增益能够大大得到提升,从而提高终端设备与接入网设备之间的通信性能。其次,相比于接入网设备从M个发送波束中选择一个发送波束与终端设备进行通信传输的方式来说,第一发送波束对应的信道容量最大化,提升了第一发送波束对应的信道的容量。该M个发送波束为该接入网设备生成的与M个参考信号资源对应的M个发送波束,该M个发送波束为固定权值的发送波束。

另一种可能的实现方式中,该M个参考信号资源中的该N个参考信号资源是由该终端设备通过同一接收波束接收的。
在该可能的实现方式中,由于接入网设备基于终端设备使用同一接收波束测量得到该N个参考信号资源对应的N个参考信号的幅度信息(即该N个参考信号的RSRP)和该N个参考信号的第一相位信息计算生成的第一发送波束。因此,在终端设备侧应当对终端设备的接收波束进行限定,以便于接入网设备生成匹配终端设备与接入网设备之间的信道条件的第一发送波束,从而提高终端设备与接入网设备之间进行通信的通信性能。

下面对本申请涉及的一些术语作介绍。
波束(beam):波束是一种通信资源。波束可以是宽波束,或者窄波束,或者其他类型波束。形成波束的技术可以是波束成形技术或者其他技术手段。波束成形技术可以具体为数字波束成形技术、模拟波束成形技术和混合数字/模拟波束成形技术。不同的波束可以认为是不同的资源。通过不同波束可以发送相同的信息或不同的信息。可选的,可以将具有相同或者类似的通信特征的多个波束视为是一个波束。一个波束内可以包括一个或多个天线端口,用于传输数据信道、控制信道和探测信号等。例如,发射波束可以是指信号经过天线发射出去后在空间不同方向上形成的信号强度的分布。接收波束可以是指从天线上接收到的无线信号在空间不同方向上的信号强度分布。可以理解的是,形成一个波束的一个或多个天线端口也可以看作是一个天线端口集。波束在协议中的体现还可以是空域滤波器(spatial filter)。

图1为本申请实施例通信系统的一个示意图。该通信系统包括一个或多个接入网设备100(图1中仅示出一个)和一个或多个终端设备(图1示出的两个终端设备,分别为终端设备101和终端设备102)。该与接入网设备100分别与该一个或多个终端设备连接。
接入网设备100为具有无线收发功能的设备,用于与终端设备101进行通信。该接入网设备100包括但不限于基站,而基站包括各种形式的宏基站、微基站、中继站、接入网点。示例性的,本申请实施例中基站可以是新空口(new radio,NR)中的基站、发送接收点(transmission reception point,TRP)、传输点(transmission point,TP)、小站、下一代节点B(next generation Node B,ngNB)、wifi系统中的接入节点、无线中继节点、或者无线回传节点,也可以是长期演进(long term evolution,LTE)系统中的演进型节点B(evolutional Node B,eNB或eNodeB)、或者云无线接入网络(cloud radio access network,CRAN)场景下的无线控制器。接入网设备100还可以是可穿戴设备、车载设备等。

为了提高接入网设备与终端设备之间的通信性能,终端设备可以向接入网设备上报信道信息,该信道信息用于表征该终端设备与接入网设备之间的信道条件。这样,接入网设备可以根据该信道信息生成匹配该信道条件的发送波束,从而提高该接入网设备与终端设备之间的通信性能。
因此,本申请实施例中,接入网设备生成匹配该信道条件的发送波束可以从波束管理演进到波束计算。本申请实施例中,通过参考信号的幅度信息(例如,参考信号的信号质量)和参考信号的相位信息反映该信道条件为例进行介绍。在实际应用中,还可以通过其他参数表征该信道条件。例如,还可以包括以下参数中的一项或多项:时延扩展(delay spread),多普勒扩展(doppler spread),多普勒频移(doppler shift),平均时延(average delay),平均增益,空间接收参数(spatial Rx parameters)。其中,空间接收参数包括以下的一项或多项:到达角(angle of arrival,AOA)、平均AOA、AOA扩展、离开角(angle of departure,AOD)、平均离开角AOD、AOD扩展、接收天线空间相关性参数、发送天线空间相关性参数。

一、在波束管理流程中,终端设备向该接入网设备上报N个参考信号的幅度信息时,也向接入网设备上报该终端设备测量N个参考信号得到的第一相位信息;然后,接入网设备根据该第一相位信息和该N个参考信号的幅度信息生成第一发送波束。具体请参阅图2A所示的实施例的相关介绍。
二、本申请实施例新增波束合成流程,该波束合成流程可以在波束管理流程之后执行。终端设备在波束合成流程中测量接入网设备通过接入网设备的R个端口发送的第二参考信号资源的第二相位信息,并向接入网设备上报该第二相位信息;然后,接入网设备根据该第二相位信息和参考信号的幅度信息生成第二发送波束,其中,该参考信号的幅度信息可以为该R个端口的第二参考信号资源的参考信号的幅度信息,或者是,在波束管理过程中,终端设备测量并上报的N个参考信号的幅度信息。具体请参阅图3A所示的实施例的相关介绍。

下面结合实施例介绍本申请实施例的通信处理方法。
请参阅图2A,图2A为本申请实施例通信处理方法的一个实施例示意图。在图2A中,该方法包括:
201、接入网设备向终端设备发送M个参考信号资源。相应的,终端设备接收接入网设备发送的M个参考信号资源。
步骤201具体为:接入网设备按照M个参考信号资源的配置向终端设备分别发送的M个参考信号,相应的,终端设备按照该M个参考信号资源的配置接收该接入网设备分别发送的M个参考信号。
可以理解的是,本申请实施例中,下面描述方式1和描述方式2是等效的。
描述方式1:接入网设备向终端设备发送M个参考信号资源。
描述方式2:接入网设备按照该M个参考信号资源的配置向终端设备分别发送该M个参考信号。
同理,以下描述方式3和描述方式4是等效的。
描述方式3:终端设备接收接入网设备发送的M个参考信号资源等效于。
描述方式4:终端设备按照该M个参考信号资源的配置接收该接入网设备分别发送的M个参考信号。
本实施例中,该M个参考信号资源中的每个参考信号资源对应一个发送波束,且不同的参考信号资源对应的发送波束相同或不同。需要说明的是,该M个参考信号资源分别对应的发送波束中应当包括至少两个不同的发送波束。
可选的,该M个参考信号资源与M个发送波束一一对应,即每个参考信号资源都有对应发送波束,且不同参考信号资源对应不同的发送波束。
该M个发送波束为该接入网设备生成的分别与该M个参考信号资源对应的发送波束,该M个发送波束为固定权值的发送波束。其中,固定权值的发送波束也称为固定(fixed,或者static)模拟发送波束,或固定图样(pattern)模拟发送波束,或固定码本(codebook)模拟发送波束,或者基础基础(basic)模拟发送波束。码本也可以称为权(weight vector或者weight matrix),因此后文称该M个发送波束为固定权值的发送波束。
其中,固定图样(pattern)是指设备所能产生的模拟发送波束的数目、每个模拟发送波束的主瓣的指向、波束宽度、波束增益等特征参数是固定的,该特征参数并不随着时间的变化而变化。
具体的,接入网设备通过M个参考信号资源并通过M个发送波束分别发送M个参考信号,该M个参考信号资源与该M个参考信号之间一一对应,该M个参考信号资源与M个发送波束一一对应。然后,终端设备通过该M个参考信号资源分别接收该M个参考信号。
可选的,该M个参考信号为M个CSI-RS,该M个参考信号资源为CSI-RS资源。
本实施例中,一种可能的实现方式中,该M个参考信号资源用于波束管理。
根据通信标准TS 38.214规定,单端口(port)或两端口的单符号(symbol)并且频域密度(density)为1或3的CSI-RS资源才能用于波束管理。下面以单端口的单符号且频域密度为3的CSI-RS资源为例介绍接入网设备发送该CSI-RS资源对应的CSI-RS的过程。
例如,如图2B所示,横坐标为正交频分复用(orthogonal frequency division multiplexing,OFDM)符号,纵坐标为频率,以资源单元(resource element,RE)为粒度。如图2B中,一个时隙(slot)中的一个资源块(resource block,RB)包括的三个RE被一个CSI-RS资源占据,即可以理解为该CSI-RS资源在RB中的位置为图2B所示的阴影部分(该RB中的三个RE)的位置,而该CSI-RS资源占用RB的个数具体由接入网设备配置。并且,每个CSI-RS资源都有对应的发送波束,不同的CSI-RS资源对应的发送波束不同。
若接入网设备生成16个发送波束,该16个发送波束为固定权值的发送波束,那么接入网设备可以通过16个slot并通过16个发送波束分别发送16个CSI-RS。16个CSI-RS资源分别位于16个slot上,16个CSI-RS资源与16个发送波束一一对应,16个CSI-RS与16个CSI-RS资源一一对应,从而实现终端设备对该16个CSI-RS的测量。
例如,如图2C所述,横坐标为OFDM符号,纵坐标为频率,以RE为粒度。如图2C所示,一个slot中可以发送四个CSI-RS资源。每个CSI-RS资源占据一个slot中的一个RB包括的三个RE,具体如图2C所示,不同类型的阴影部分表示不同的CSI-RS资源分别占用不同RB的三个RE的位置,而每个CSI-RS资源占用RB的个数具体由接入网设备配置。并且,每个CSI-RS资源都有对应的发送波束,不同的CSI-RS资源对应的发送波束不同。
若接入网设备生成16个发送波束,该16个发送波束为固定权值的发送波束。那么,接入网设备可以分别通过4个slot发送16个CSI-RS。16个CSI-RS资源对应位于4个slot上,,16个CSI-RS资源与16个发送波束一一对应,16个CSI-RS与16个CSI-RS资源一一对应,从而实现终端设备对该16个CSI-RS的测量。
本实施例中,接入网设备可以周期性的,或半持续的,或非周期性的发送该16个CSI-RS。例如,每隔一个周期(例如,20ms),接入网设备按照该16个CSI-RS的资源配置发送一遍该16个CSI-RS。
202、终端设备测量M个参考信号资源,得到第一测量信息。
该第一测量信息包括第一相位信息。该第一相位信息为该终端设备分别测量N个参考信号得到的相位信息。该M个参考信号资源包括该N个参考信号资源,N和M均为大于或等于1的整数,M大于或等于N。
步骤202具体为:终端设备测量该M个参考信号资源对应的M个参考信号,得到该第一测量信息。即可以理解的是,终端设备测量M个参考资源,得到第一测量信息等效于终端设备测量该M个参考信号资源对应的M个参考信号,得到该第一测量信息。
一种可能的实现方式中,该终端设备测量该M个参考信号资源对应的M个参考信号,得到该M个参考信号的RSRP;然后,该终端设备从该M个参考信号选择该N个参考信号。终端设备测量该N个参考信号,得到该N个参考信号的第一相位信息。
另一种可能的实现方式中,该终端设备测量该M个参考信号资源对应的M个参考信号,得到该M个参考信号的RSRP和该M个参考信号的相位信息;然后,该终端设备从该M个参考信号的RSRP和该M个参考信号的相位信息选择N个参考信号的RSRP和该N个参考信号的第一相位信息。
由上述两种可能的实现方式中任一种可能的实现方式中,终端设备可以得到该第一测量信息,该第一测量信息包括该N个参考信号的RSRP、该N个参考信号的CRI以及该第一相位信息。
本实施例中,为了接入网设备能够生成匹配终端设备与接入网设备之间的信道条件的第一发送波束且该第一发送波束所对应的信道容量最大化,终端设备从M个参考信号中选择N个参考信号时,应当使得选择得到的N个参考信号对应的N个发送波束构成的信道容量最大或者该N个发送波束构成的信道的秩(rank)最高。
具体的,接入网设备在M个参考信号资源通过M个发送波束分别发送M个参考信号,该M个参考信号资源分别与接入网设备生成的M个发送波束一一对应,且该M个发送波束是固定权值的发送波束。由于M个参考信号的RSRP可以反映M个发送波束的波束质量,终端设备可以按照RSRP的大小顺序从大到小从该M个参考信号中选择N个参考信号,从而使得该N个参考信号对应的N个发送波束构成的信道容量最大化。
需要说明的是,接入网设备可以配置终端设备上报N个参考信号对应的RSRP和第一相位信息,也可以是通信协议规定终端设备上报N个参考信号对应的RSRP和第一相位信息,具体本申请不做限定。
本实施例中,第一相位信息包括的内容形式为参考信号的相位,或者不同参考信号之间的相位差。
一、针对第一相位信息包括参考信号的相位的方式,则第一相位信息包括该N个参考信号资源对应的N个参考信号的相位。
终端设备测量该N个参考信号的相位;然后,终端设备通过指示信息向接入网设备上报该N个参考信号的相位,或者,终端设备直接向该接入网设备上报该N个参考信号的相位。
由于后续步骤204中接入网设备生成第一发送波束所需的参数包括N个参考信号之间的相位差,因此接入网设备根据该N个参考信号的相位计算得到该N个参考信号之间的相位差。
如图2D所示,该N个参考信号包括第一参考信号和第二参考信号。图2D示出了随着频率的变化,第一参考信号的相位和第二参考信号的相位的变化情况。由此可知,参考信号的相位与发送该参考信号所使用的频率相关。因此,若终端设备要正确反映该N个参考信号的相位信息,则针对该N个参考信号资源的不同频率,终端设备需要反馈在不同频率上该N个参考信号分别对应的相位。可选的,终端设备可以通过反馈该N个参考信号的初始频率和该N个参考信号在初始频率上分别对应的初始相位,以及随着频率变化该N个参考信号分别对应的相位变化(也即参考信号的相位与频率之间的线性关系所对应的斜率),以反馈在不同频率上该N个参考信号分别对应的相位。
二、针对第一相位信息包括不同参考信号之间的相位差的方式,那么第一相位信息具体包括以下任一种:
1、该N个参考信号资源分别对应的相位之间的相位差。
具体的,该第一相位信息包括该N个参考信号资源对应的N个参考信号分别对应的相位之间的相位差。在该实现方式中,该第一相位信息具体包括N*(N-1)个相位差。
例如,N个参考信号资源包括参考信号资源1、参考信号资源2和参考信号资源3,该参 考信号资源1对应相位1,该参考信号资源2对应相位2,参考信号资源3对应相位3。那么可知,第一相位信息包括相位1与相位2之间的相位差,相位2与相位3之间的相位差,以及相位1与相位3之间的相位差。
2、该N个参考信号资源分别对应的相位与第一基准相位之间的相位差。
具体的,该第一相位信息包括该N个参考信号资源对应的N个参考信号分别对应的相位与第一基准相位之间的相位差。在该实现方式中,该第一相位信息具体包括N-1个相位差。
本实施例中,终端设备是在波束管理流程中测量得到的第一相位信息(具体为该终端设备测量该N个参考信号中除该第一基准相位对应参考信号之外的其他参考信号,得到该其他参考信号的相位与第一基准相位的相位差),因此上述第一测量信息包括第一相位信息之外,该第一测量信息还包括该N个参考信号资源对应的N个CRI、该N个参考信号资源的RSRP(即该N个参考信号资源对应的N个参考信号的RSRP)。
可选的,该第一基准相位包括以下任一种可能的形式:
1、该第一基准相位为该N个参考信号资源中RSRP最大的参考信号资源对应的相位。
具体的,该第一基准相位为该N个参考信号资源对应的N个参考信号中RSRP最大的参考信号的相位。
由于在波束管理流程中,终端设备上报RSRP时,是以上报的RSRP中最大的RSRP为基准RSRP。因此,终端设备可以以该RSRP最大的参考信号的相位为第一基准相位,以适应波束管理流程中RSRP上报机制。
2、该第一基准相位为该N个参考信号资源中RSRP最小的参考信号资源对应的相位。
具体的,该第一基准相位为该N个参考信号资源对应的N个参考信号中RSRP最小的参考信号的相位。
3、该第一基准相位为该N个参考信号资源中RSRP大于或等于第一预设阈值的参考信号资源。
具体的,该第一基准相位为该N个参考信号资源对应的N个参考信号中RSRP大于或等于第一预设阈值的参考信号的相位。
可选的,第一预设阈值的取值为-140dBm(分贝毫瓦)、-116dBm、或、-108dBm等。
第一预设阈值的取值设定因素包括:终端设备的接收机灵敏度、支持最低调制编码方式所需的信号强度、支持最低传输速率所需的信号强度、终端设备与接入网设备之间的信道状态,当前的网络传输条件等。
4、该第一基准相位为该N个参考信号资源中接入网设备最先发送的参考信号资源。
具体的,该第一基准相位为该N个参考信号资源对应的N个参考信号中该接入网设备最先发送的参考信号。
如图2C所示,若N个参考信号资源中包括四个CSI-RS资源,四个CSI-RS资源分别对应图2C的四种类型的阴影部分的时频资源。接入网设备将在图2C上的阴影部分的时频资源分别发送四个CSI-RS。如图2C所示,接入网设备最先发送的是承载于第11个OFDM符号上的CSI-RS,那么接入网设备以该CSI-RS的相位为第一基准相位。
5、该第一基准相位为该N个参考信号资源中接入网设备最后发送的参考信号资源。
具体的,该第一基准相位为该N个参考信号资源对应的N个参考信号中该接入网设备最后发送的参考信号。
如图2C所示,若N个参考信号资源中包括四个CSI-RS资源,四个CSI-RS资源分别对应图2C的四种类型的阴影部分的时频资源。接入网设备将在图2C上的阴影部分的时频资源分别发送四个CSI-RS。如图2C所示,接入网设备最后发送的是承载于第14个OFDM符号上的CSI-RS,那么接入网设备以该CSI-RS的相位为第一基准相位。
6、该第一基准相位为该N个参考信号资源中参考信号资源标识最大的参考信号资源。
7、该第一基准相位为该N个参考信号资源中参考信号资源标识最小的参考信号资源。
其中,参考信号资源标识为CSI-RS resource ID。
上述示出了第一基准相位的一些可能的实现方式,在实际应用中,还可以有其他实现方式,具体本申请对第一基准相位的选取不做限定。
针对第一相位信息包括的是参考信号之间的相位差的方式,终端设备无需上报每个参考信号对应的相位,从而节省信令开销。其次,如图2D所示,在不同的频率下,第一参考信号与第二参考信号之间的相位差的差异较小,即第一参考信号与第二参考信号之间的相位差在不同频率下较为平稳,终端设备无需上报两个参考信号在不同的频率下的相位差,进一步地减少信令开销。
本实施例中,该N个参考信号资源是由该终端设备通过同一接收波束接收的。
具体的,该终端设备通过同一接收波束接收该接入网设备发送的该N个参考信号资源对应的N个参考信号。
由于在步骤204中,接入网设备基于终端设备使用同一接收波束测量得到该N个参考信号资源对应的N个参考信号的幅度信息(即该N个参考信号的RSRP)和该N个参考信号的第一相位信息计算生成的第一发送波束。因此,在终端设备侧应当对终端设备的接收波束进行限定,以便于接入网设备生成匹配终端设备与接入网设备之间的信道条件的第一发送波束,从而提高终端设备与接入网设备之间进行通信的通信性能。
上述步骤202中示出了终端设备测量M个参考信号资源分别对应的RSRP和N个参考信号资源对应的第一相位信息的过程。在实际应用中,终端设备测量M个参考信号资源分别对应的RSRP的过程与终端设备测量N个参考信号资源对应的第一相位信息的过程可以是独立的两个测量过程。并且,该终端设备测量M个参考信号资源分别对应的RSRP和N个参考信号资源对应的第一相位信息的测量顺序不做限定。
203、终端设备向接入网设备发送第一消息。
其中,该第一消息携带第一指示信息,该第一指示信息用于指示该第一相位信息。
本实施例中,终端设备是在波束管理流程中测量该第一相位信息并上报该第一相位信息。因此,该第一消息还携带第十二指示信息和第十三指示信息,该第十二指示信息用于指示该N个参考信号资源分别对应的CRI。该第十三指示信息用于指示该N个参考信号资源的RSRP。
由于已有波束管理流程中终端设备上报的N个CRI对应的RSRP的方式为:终端设备使用七比特的绝对值量化方法上报该N个CRI对应的RSRP中最大的RSRP,该N个CRI对应的RSRP中 除最大的RSRP之外,都使用四比特的相对差量化方法进行上报。因此,为了匹配已有波束管理流程终端设备上报RSRP的方式,下面以该第一相位信息包括该N个参考信号资源对应的N个参考信号的相位与第一基准相位之间的相位差,且将该N个参考信号资源对应的N个参考信号中RSRP最大的参考信号作为基准相位为例介绍该第一消息携带的内容。
首先,先示出第一消息用于指示不同上报量分别所占用的比特位宽。上报量包括CRI、RSRP最大的参考信号的RSRP、RSRP差(Differential RSRP)、相位差(Differential Phase)。具体请参阅表1。
表1
在本实施例中,在已有的表格中新增上报量Differential Phase得到该表1。该Differential Phase使用四个比特上报给接入网设备。即每个相位差占用第一消息中的四个比特。
需要说明的是,上述表1仅仅是示例,本实施例对该Differential Phase占用的比特位宽不做限定。例如,Differential Phase可以占用八个比特位宽。
下面示出第一消息中各个上报量上报的字段顺序,请参阅表2:
表2
本实施例中,在已有的表格中新增该Differential Phase #2-#1、Differential Phase #3-#1和Differential Phase #4-#1这三行得到该表2。其中,Differential Phase #2-#1表示CRI#1与CRI#2分别对应的CRS-RS之间的相位差。Differential Phase #3-#1表示CRI#3与CRI#1分别对应的CRS-RS之间的相位差。Differential Phase #4-#1表示CRI#4与CRI#1分别对应的CRS-RS之间的相位差。
例如,结合上述表1,即上述Differential Phase #2-#1、Differential Phase #3-#1和Differential Phase #4-#1分别是占用四个比特。由于每个相位差的状态可以使用4个比特进行表示,因此相位差的状态共16种。由于量化范围为2*pi,因此量化精度为pi/8,下面结合表3,示出不同取值范围的相位差所对应的上报值。
表3
由表3可知,落入不同取值范围的相位差都有对应的值。例如,CRI#1对应的参考信号的相位为6/8*pi,而CRI#2对应的参考信号的相位为7/8*pi,那么该Differential Phase#2-#1落入1/8*pi≥ΔPhase>0,而1/8*pi≥ΔPhase>0对应的值为DIFFRSRP_7,那么使用四个比特表示DIFFRSRP_7,则为“0111”。对于Differential Phase #3-#1和Differential Phase #4-#1类似,具体此处不再一一说明。
上述表1和表2是一种示例,并不属于对本申请实施例的一种限定。对于表3,也可以采用其他量化精度,或者根据终端设备能够支持的其他量化精度来表示该相位差。例如,采用终端设备支持的量化精度1/4*pi,由于量化范围为2*pi,则可知相位差的状态一共有8种。下面结合表4,示出不同取值范围的相位差所对应的值:
表4
由表3和表4可知,相位差的状态表示的总数由量化范围的大小和量化精度确定的。并且,前述表1中每个相位差占用的比特位宽与相位差的状态的总数相关。例如,表3中的相位差的状态表示一共有16种,因此每个相位差占用的比特位宽至少为4比特。
上述表1和表2仅仅是为了介绍第一消息携带的第一指示信息的具体形式。在实际应用中,终端设备上报第一指示信息也可以通过其他形式上报,并不依赖波束管理流程中RSRP的上报方式,只要接入网设备与终端设备双方预先约定好上报方式,接入网设备能够正确解析终端设备的上报信息即可。
本实施例示出了终端设备通过指示信息上报该第一相位信息和N个参考信号资源对应 的N个参考信号的幅度信息(例如,N个参考信号的RSRP)的方式,避免了信令开销过大的问题,从而减少资源开销。在实际应用中,该终端设备也可以直接向接入网设备上报该第一相位信息和N个参考信号资源对应的N个参考信号的幅度信息,具体本申请不做限定。
上述步骤203示出了终端设备通过同一消息(第一消息)向接入网设备上报第一指示信息、第十二指示信息和第十三指示信息的方式。在实际应用中,该第一指示信息、第十二指示信息和第十三指示信息可以分别通过不同的消息发送给接入网设备,或者,也可以是第十二指示信息和第十三指示信息通过一个消息发送给接入网设备,而第一指示信息通过另一个消息发送给接入网设备,具体本申请不做限定。后文以终端设备通过同一消息(第一消息)向接入网设备上报第一指示信息、第十二指示信息和第十三指示信息的方式为例介绍本申请实施例的技术方案。
204、接入网设备根据第一指示信息指示的第一相位信息生成第一发送波束。
其中,该第一发送波束用于该接入网设备与该终端设备之间进行通信。
具体的,第一消息还携带第十二指示信息和第十三指示信息,该第十二指示信息用于指示N个参考信号资源对应的N个CRI,该第十三指示信息用于指示该N个CRI对应的N个参考信号的RSRP。接入网设备根据该第十二指示信息和该第十三指示信息确定该N个参考信号的RSRP,该接入网设备根据该第一指示信息确定该N个参考信号的第一相位信息。然后,接入网设备根据该N个参考信号的第一相位信息和该N个参考信号的RSRP生成第一发送波束。
本实施例中,在上述步骤201之前,接入网设备确定第一权值集合。
其中,M个发送波束中的第b
i个发送波束的权值表示为
i为大于或等于0且小于或等于M-1的整数。
是一个维度为N
t-ans×1的向量,N
t-ans为接入网设备中用于发送第b
i个发送波束对应的参考信号的天线阵子数目。
本实施例中,接入网设备用于发送该M个发送波束中每个发送波束对应的参考信号的天线阵子数目相同或不同,终端设备用于接收该M个发送波束中每个发送波束对应的参考信号的射频通道数目相同或不同。
为了描述方便,在后文步骤204a至步骤204b中,以接入网设备中用于发送该M个发送波束中每个发送波束对应的参考信号的天线阵子数目都为N
t-ans为例进行介绍,以终端设备中用于接收该M个发送波束中每个发送波束对应的参考信号的射频通道数目都为N
r为例进行介绍。
由于测量和计算的复杂度,接入网设备配置终端设备上报N个参考信号资源对应的N个参考信号的幅度信息(即N个参考信号分别对应的RSRP)和N个参考信号对应的第一相位信息。在高频通信中,由于高频信道具有稀疏性,也就是说绝大部分能量分布在少数的几个 发送波束的覆盖范围。示例性的,M个发送波束中对应RSRP强度最大的N个发送波束为该终端设备测量上报的该N个参考信号的第一相位信息对应的N个发送波束。
为了描述方便,后文以W
N包括该M个发送波束中的前N个发送波束的权值为例进行说明。在实际应用中,W
N包括的是该终端设备测量并上报的N个RSRP对应的N个发送波束的权值,具体该N个发送波束可以为M个发送波束对应的M个参考信号中RSRP排在前N的N个RSRP分别对应的N个发送波束。
本实施例中,为了生成与终端设备与接入网设备之间的信道条件匹配的第一发送波束,扩展了终端设备上报的内容(在已有波束管理流程中终端设备上报N个参考信号的RSRP基础上,新增上报N个参考信号的第一相位信息),通过该N个参考信号的RSRP和该第一相位信息体征该终端设备与接入网设备之间的信道条件。
下面以终端设备上报N个参考信号的第一相位信息和该N个参考信号的幅度信息为例介绍步骤204。步骤204具体包括步骤204a和步骤204b。该N个参考信号的幅度信息也称为N个发送波束的幅度信息(即N个参考信号的RSRP,后文步骤204a和步骤204b中统称该N个参考信号的幅度信息)。
步骤204a:接入网设备根据该第一相位信息和该N个参考信号的幅度信息确定第一合成权α
opt1。
其中,该N个参考信号的幅度信息包括该N个参考信号的RSRP。该第一合成权α
opt1用于接入网设备生成匹配终端设备与接入网设备之间的信道条件的第一发送波束。
下面介绍接入网设备计算第一合成权α
opt1的过程:
1、接入网设备确定该N个发送波束中的每个发送波束的信道。
为了计算第一合成权α
opt1,接入网设备需要获得该N个发送波束中的每个发送波束的信道。以固定权值为w
b0的发送波束为例,终端设备测量得到:针对子载波k来说,该固定权值为w
b0的第b
0个发送波束的信道为
为了使得该N个发送波束构成的信道容量最大化,接入网设备计算满足该信道容量最大 化要求的第一合成权α
opt1。因此,具体可以将问题定位为解如下式(1)的最优化问题:
argmax为极大值自变量(arguments of the maxima)的操作符,k为子载波的编号。上述式(1)描述的最优化问题指:在所有的α找到第一合成权α
opt1,使得上述式(1)中的
的值最大。
需要说明的是,基于不同的准则,需要求解答的优化问题可能不同。上述示出的最优化问题是基于信道容量最大化的基则确定的最优化问题。
可选的,式(1)的最优化问题的解受限于α恒模(subject to(s.t.)||α||
2=1)。
那么可知将问题定位为解下述式(1)和式(2)的最优化问题:
s.t.||α||
2=1 (2)
式(2)为一种高频器件的恒模限制的数学表达式。
那么,解上述式(1)和式(2),得到上述最优化问题的一个近似解如下:
α
opt1=v
1 (3)
其中,v
1为信道协方差矩阵R最大特征值对应的右奇异向量或特征向量。信道协方差矩阵R为:
其中,(·)
*是为复数共轭操作符,(·)′是为共轭转置操作符,k为子载波的编号,k的取值与参考信号的传输带宽相关。那么可知,对于子载波k来说,信道协方差矩阵R
k如下:
其中,式(5)的信道协方差矩阵的主对角线的元素(这里将主对角线的元素称为对角线元素)为同一发送波束的幅度的平方,而式(5)中的信道协议方差矩阵中除上述对角线元素之外的其他元素(这里称为非对角线元素)为不同发送波束的幅度的相关。
第一行第一列的元素(即对角线元素)实际上是第一个发送波束对应的参考信号的幅度的平方,即该第一个发送波束对应的参考信号的接收能量。具体表示为:
因此,接入网设备根据第一相位信息得到该N个发送波束对应的N个参考信号之间的相位差;然后,接入网设备根据该N个参考信号之间的相位差确定该N个参考信号的相位,并根据该N个参考信号的相位和该N个参考信号的RSRP(也称为该N个发送波束的幅度信息)生成第一合成权α
opt1。
需要说明的是,上述式(4)和式(5)是以该N个发送波束对应的N个参考信号的传输带宽范围相同为例进行介绍接入网设备计算第一合成权α
opt1的过程。在实际应用中,该N个参考信号的传输带宽范围也可以不同。对于N个参考信号的传输带宽范围不同的情况,下面以发送波束w
b0对应的参考信号和发送波束w
b1对应的参考信号之间的相位差的确定过程为例介绍N个发送波束分别对应的N个参考信号之间的相位差的确定过程。对于其他参考信 号之间的相位差的获取同样适用。
若
与
之间没有重叠,则对
范围内的发送波束w
b1对应的参考信号的相位进行调整,得到
范围内的发送波束w
b1对应的参考信号的相位,再计算该发送波束w
b1对应的参考信号与发送波束w
b0对应的参考信号之间的相位差。具体的调整方式为:接入网设备根据发送波束w
b1对应的参考信号的相位和频率之间的线性关系进行调整。例如,子载波1的发送波束w
b1对应的参考信号的相位等于子载波2的发送波束w
b1对应的参考信号的相位加上斜率*(子载波1的频率-子载波2的频率),斜率为发送波束w
b1对应的参考信号相位与频率之间的线性关系所对应的斜率。
这样,接入网设备可以获得在同一带宽范围内N个发送波束对应的参考信号的相位差,再构成类似上述式(4)的信道协方差矩阵,从而实现对第一合成权α
opt1的确定。
上述式(4)和式(5)是以子载波的粒度介绍接入网设备计算得到第一合成权α
opt1的过程。在实际应用中,还可以以其他带宽作为粒度计算该第一合成权α
opt1。例如,RE粒度、RB粒度、资源块组(resource block group,RBG)粒度、或全带粒度等。
步骤204b:接入网设备根据该第一合成权α
opt1和第二权值集合W
N生成该第一发送波束W
opt,即W
opt=W
N*α
opt1。
其中,该第一发送波束匹配该终端设备与接入网设备之间的信道条件,且第一发送波束对应的信道容量最大化。
由此可知,第一发送波束的主瓣方向对准该终端设备,那么接入网设备与该终端设备通过第一发送波束进行通信传输,第一发送波束的波束增益能够大大得到提升,从而提高 终端设备与接入网设备之间的通信性能。其次,相比于接入网设备从M个发送波束中选择一个发送波束与终端设备进行通信传输的方式来说,第一发送波束对应的信道容量最大化,提升了第一发送波束对应的信道的容量。该M个发送波束为该接入网设备生成的与M个参考信号资源对应的M个发送波束,该M个发送波束为固定权值的发送波束。
可选的,第一发送波束不属于发送波束集合,该发送波束集合包括M个发送波束,该M个发送波束分别对应的权值由前述第一权值集合表示,该M个发送波束为固定权值的发送波束。
205、接入网设备通过该第一发送波束与该终端设备通信。
具体的,步骤205包括以下至少一项操作:
1、接入网设备通过第一发送波束向该终端设备发送第一参考信号资源对应的参考信号;然后,终端设备测量第一参考信号资源对应的参考信号,从而得到该第一发送波束对应的信道信息。
本实施例中,接入网设备在发送第一参考信号资源对应的参考信号之前,该接入网设备向终端设备发送第九指示信息。
该第九指示信息用于指示该终端设备通过第一接收波束接收该第一参考信号资源,该第一接收波束为该终端设备接收该N个参考信号资源所对应的N个参考信号所采用的接收波束。
具体的,该接入网设备通过第一RRC信令中的准共址信息周期性信道状态信息参考信号(qcl-InfoPeriodicCSI-RS)字段配置该第一参考信号资源的TCI状态。具体的配置过程为接入网设备将该第一参考信号资源的TCI中的referencesignal值配置为该N个参考信号资源中的任一个参考信号资源的ID。然后,接入网设备向该终端设备发送该第一RRC信令。这样,终端设备根据该第一RRC信令确定通过该第一接收波束接收该第一参考信号资源对应的参考信号。
2、接入网设备通过该第一发送波束向该终端设备发送第十指示信息。该第十指示信息用于指示对终端设备通过第一接收波束进行上行传输、下行传输和控制信道传输。
该第十指示信息包括前述表2中的任一CRI所对应的CRS-RS resource ID,或者,包括该第一参考信号资源对应的CRS-RS resource ID。
具体的,该接入网设备通过第二RRC信令中的TCIstate或者空间关系信息(spatialRelationInfo)来配置该终端设备的用于上行传输资源、下行传输资源和控制信道传输资源的波束。
具体的配置过程为接入网设备将该终端设备的用于上行传输资源、下行传输资源和/或控制信道传输资源的TCIstate或者spatialRelationInfo中的参考信号(referencesignal)值配置为该N个参考信号资源中的任一个参考信号资源的ID;或者,接入网设备为将该终端设备的用于上行传输资源、下行传输资源和/或控制信道传输资源的TCIstate或者spatialRelationInfo中的referencesignal值配置为第一参考信号资源对应的CRS-RS resource ID;然后,接入网设备向该终端设备发送第二RRC信令。这样,终端设备根据该第二RRC信令确定通过该第一接收波束进行上行传输、下行传输和/或控制信道传 输。
3、接入网设备通过该第一发送波束与终端设备进行下行传输,以及通过第一发送波束与终端设备进行上行传输。
在下行传输过程中,终端设备对该第一发送波束进行时频偏跟踪。具体终端设备可以通过测量第一参考信号资源得到时频偏;或者,终端设备测量接入网设备发送的与第一参考信号资源的跟踪参考信号得到该时频偏;或者,终端设备测量用于合成该第一发送波束的N个参考信号资源得到该时频偏。
在上行传输过程中,终端设备对第一发送波束进行路径损耗测量。具体终端设备可以测量该第一参考信号资源得到路径损耗;或者,终端设备可以测量接入网设备发送的与第一参考信号资源关联的路损参考信号得到路径损耗;或者,终端设备测量该N个参考信号资源对应的参考信号得到路径损耗。
本申请实施例中,终端设备测量该N个参考信号资源,得到该N个参考信号资源的幅度信息和第一相位信息,并向接入网设备上报该N个参考信号资源的幅度信息和第一相位信息。在终端设备的移动过程中,接入网设备与终端设备之间的信道条件是不停变化的,而N个参考信号资源分别对应接入网设备的N个发送波束。因此,N个参考信号资源的幅度信息和第一相位信息可以体征该接入网设备与终端设备的信道变化情况,这样接入网设备可以N个参考信号资源的幅度信息和第一相位信息生成匹配终端设备与接入网设备之间的信道条件的第一发送波束,或者,从该接入网设备的N个发送波束中选择匹配终端设备与接入网设备之间的信道条件的第一发送波束,以提升接入网设备与终端设备之间的通信性能。
为了接入网设备为终端设备配置合适的资源配置和上报方式,以便于接入网设备正确解析终端设备的上报量。可选的,上述图2A所示的实施例还包括步骤206和步骤207,且步骤206和步骤207在步骤201之前执行。
206、终端设备向接入网设备发送该终端设备的第一能力信息。
第一能力信息携带第二指示信息,该第二指示信息的指示形式包括以下任一种:
1、第二指示信息用于指示该终端设备是否支持动态发送波束所需的测量和上报;
2、第二指示信息用于指示该终端设备是否具备对第一相位信息进行测量的测量能力;
3、第二指示信息用于指示该终端设备是否支持用于波束管理的参考信号资源对应的相位信息的测量。
本实施例中,为了接入网设备能够确定终端设备是否具备测量参考信号的相位信息的测量能力,终端设备可以向接入网设备上报该终端设备的第一能力信息。这样接入网设备能够正确对终端设备进行资源配置和上报方式的配置,以避免出现接入网设备无法解析正确该终端设备的上报量。
需要说明的是,上述步骤206中示出了终端设备通过第一能力信息上报第二指示信息的方式,在实际应用中,该终端设备也可以单独向接入网设备发送该第二指示信息,或者,终端设备也可以通过其他信息或消息携带该第二指示信息并上报给接入网设备,具体本申请不做限定。
可选的,终端设备在终端设备接入网络时或者在网络请求时执行上述步骤206。
具体的,在波束管理流程中,终端设备向接入网设备上报该第一能力信息,该第一能力信息承载在RRC消息中,那么终端设备通过在该RRC消息新增信元并通过该新增信元指示该终端设备对参考信号的相位信息的测量能力。

该量化能力信息包括相位差步长上报字段和支持的量化精度字段。下面采用标准中ASN.1伪代码形式表示相位差步长上报字段和支持的量化精度字段:

207、接入网设备向终端设备发送第一配置信息。
该第一配置信息用于配置该终端设备上报N个参考信号资源对应的第一相位信息。
该第一配置信息包括第一资源集合的第二配置信息,该第二配置信息用于配置该终端设备不期待接入网设备使用相同的发送空域滤波器(即发送波束)发送该第一资源集合中的所有参考信号资源。该第一资源集合包括该M个参考信号资源。
具体的,该第二配置信息包括repetition字段。本实施例中,该repetition字段为OFF,表示该终端设备不期待接入网设备使用相同的发送空域滤波器发送该第一资源集合的所有参考信号资源。
需要说明的是,若repetition字段为ON,则表示终端设备期待接入网设备使用相同的发送空域滤波器发送该第一资源集合的所有参考信号资源,而针对repetition字段为ON的情况,显然不适合本实施例中接入网设备进行多发送波束合成的场景。总体来说,若上报 量包含相位信息时,则关联的信道测量ResourceConfig#1中repetition字段不能被配置为ON。
下面结合图2E示出第一配置信息的具体形式。
如图2E所示,第一配置信息包括上报量cri-RSRP-Phase、上报数目nrofReportedRS和信道测量ResourceConfig#1(信道测量ResourceConfig#1可以理解为上述的第二配置信息。当上报量配置为cri-RSRP-Phase时,则ResourceConfig#1中的repetition字段为OFF。
可选的,第一相位信息的上报与CRS-RSRP解耦。因此,图2E所示的上报量配置也可以有其他表述形式。例如,第一相位信息的上报配置为CRI-Phase或者Phase。那么在该实现方式中,在波束管理流程中完成对RSRP上报,并且CRI-Phase或者Phase关联上报量CRS-RSRP,具体可以在第一配置信息中通过指示信息指示该CRI-Phase或者Phase关联上报量CRS-RSRP。
另外,在波束管理流程中,RSRP的上报粒度为全带上报粒度,即意味着终端设备在不同频率资源上测量得到的RSRP进行线性平均之后再上报。本实施例中,RSRP和第一相位信息的上报方式,可以采用全带上报方式,也可以采用子带上报方式,具体本申请不做限定。
其中,子带的粒度可以由接入网设备配置,或者由终端设备决定,或者由通信协议预先配置。
子带的粒度与接入网设备的调度带宽、CSI-RS资源的带宽、CSI-RS资源的数目等因素相关。例如,当CSI-RS资源的带宽较大时,考虑到频率选择性,在不同的频率资源上测量参考信号得到的RSRP和相位信息的差异较大,那么终端设备使用子带上报方式上报该第一相位信息和该N个参考信号的RSRP。
可选的,本实施例中,上报量CRI、RSRP和Phase的上报周期相同或者不同。如果CRI-RSRP为上报量,那么每次上报都包括CRI和RSRP。下面示出一种可能的Phase的上报周期:
T_Phase=接收波束数目*T_RSRP
其中,Phase的上报周期为T_Phase,CRI-RSRP的上报周期为T_RSRP。该T_Phase与T_RSRP成正比例关系。该接收波束数目为终端设备用于接收参考信号资源对应的参考信号的接收波束数目,是终端设备的一种固有能力。
可选的,该接收波束数目为预先配置在接入网设备上的,或者是,由该终端设备向该接入网设备上报的。例如,该终端设备可以在步骤206中的第一能力信息携带该终端设备支持的最大接收波束数目(maxNumberRxBeam)。
最大接收波束数目用于定义该终端设备是否支持利用CSI-RS资源进行接收波束切换。具体的,终端设备应当指示一个数值,用于表明其偏好的一个CSI-RS资源集中的CSI-RS资源重复次数。对于高频终端设备必须支持接收波束的切换。关于最大接收波束数目的相关介绍可以参阅通信标准TS.38.306。
因此,综上所述,可选的,该第一配置信息还包括以下至少一项信息:
1、第三指示信息,该第三指示信息用于指示该第一资源集合用于接入网设备生成第一发送波束,该第一资源集合包括M个参考信号资源;
2、第一相位信息的上报粒度信息;
该上报粒度信息包括全带上报粒度或子带上报粒度。
3、当第一相位信息的上报粒度为子带上报粒度时,每个子带的大小。例如,每个子带的大小为4RB,8RB或者16RB。可选的,也可以是其它粒度,例如10M(兆)。
208、终端设备根据该第一配置信息确定上报该N个参考信号资源的第一相位信息。
可选的,该终端设备根据该第一配置信息确定:该M个参考信号资源用于生成第一发送波束,和确定该第一相位信息的上报粒度。
本申请实施例还提供一种实施例,该实施例与图2A所示的实施例类似,不同的地方在于步骤203至步骤204。并且,该实施例新增步骤203a,且步骤203a在步骤203之前执行。

具体的计算过程与前述步骤204a至步骤204b类似,具体请参阅前述步骤204a和步骤204b的相关介绍,这里不再赘述。

替换后的步骤204请参阅前述图2A所示的实施例中的步骤204b的相关介绍,这里不再赘述。
请参阅图3A,图3A为本申请实施例通信处理方法的另一个实施例示意图。在图3A中,该通信处理方法包括:
301、接入网设备通过接入网设备的R个端口在R个发送波束上向终端设备第二参考信号资源。相对应地,终端设备接收该接入网设备发送的第二参考信号资源。
具体的,接入网设备通过R个发送波束并通过接入网设备的R个端口在时域上连续的R个符号发送第二参考信号资源对应的参考信号,终端设备通过第二参考信号资源接收该第二参考信号资源对应的参考信号。
其中,该R个端口与R个符号一一对应,该R个端口与该R个发送波束一一对应。
即可以理解的是,接入网设备通过接入网设备的R个端口在R个发送波束上向终端设备第二参考信号资源等效于接入网设备通过R个发送波束并通过接入网设备的R个端口在时域上连续的R个符号发送第二参考信号资源对应的参考信号。
终端设备接收该接入网设备发送的第二参考信号资源等效于:终端设备通过第二参考信号资源接收该第二参考信号资源对应的参考信号,或者终端设备按照第二参考信号资源的配置接收该第二参考信号资源对应的参考信号。
该R个发送波束为该接入网设备生成的与R个参考信号资源对应的发送波束,该R个发送波束分别为固定权值的发送波束,R为大于或等于2的整数。该固定权值的发送波束的相关介绍请参阅前述图2A所示的实施例中步骤201的相关介绍,这里不再赘述。

可选的,该R个参考信号资源用于波束管理,该第二参考信号资源用于波束合成。该接入网设备的R个端口的端口编号与波束管理流程中终端设备上报的R个CRI分别对应的R个发送波束一一对应。
具体的,第二参考信号资源是用于波束合成,即用于接入网设备生成新的发送波束,以匹配终端设备与接入网设备之间的信道条件。
可选的,该第二参考信号资源为R个端口的R个符号且频域密度(density)为1或3的CSI-RS资源。
例如,如图3B所示,第二参考信号资源为四端口的四符号且频域密度为3的CSI-RS资源。port0对应发送波束1,port1对应发送波束2,port3对应发送波束3,port4对应发送波束4。接入网设备通过接入网设备的port0、port1、port2和port3并在发送波束1、发送波束2、发送波束3和发送波束4发送第二参考信号资源。即该port0至port4都用于发送第二参考信号资源,且接入网设备在时域上跨四个连续OFDM符号发送第二参考信号资源(具体为图3B中的阴影部分的时频资源),每个符号对应一个端口。即接入网设备通过R个端口发送同一参考信号。
在图3B所示的示例的基础上,下面通过表5表示第二参考信号资源在一个slot内的位置,请参阅表5:

Row X是新引入的一列。后续终端设备上报终端设备的第二能力信息时,可以通过第二能力息指示该终端设备是否支持Row X所示的CSI-RS资源的测量。
上述表5中的变量(包括k

再例如,如图3C所示,第二参考信号资源为四端口的四符号且频域密度为1的CSI-RS资源。接入网设备通过接入网设备的port0、port1、port2和port3并在发送波束1、发送波束2、发送波束3和发送波束4发送第二参考信号资源。即该port0至port4都用于发送第二参考信号资源,且接入网设备在时域上连续跨四个OFDM符号发送第二参考信号资源(具体为图3C中带有阴影部分的时频资源),每个符号对应一个端口。即接入网设备通过R个端口发送同一参考信号。
在图3C所示的示例的基础上,下面通过表6表示第二参考信号资源在一个slot内的位置,请参阅表6:
表6
其中,(k
0,l
0)为slot的第l
0个OFDM符号和在第l
0个OFDM符号上对应第k
0个RE。例如,k
0为0,l
0为0。上述表6中的变量(包括k
0、l
0等)与通信标准TS 38.211 v16.2.0第7.4.1.5.3节的notation保持一致,具体可以参阅通信标准TS 38.211 v16.2.0第7.4.1.5.3节的notation的相关介绍。
Row Y是新引入的一列。后续终端设备上报终端设备的第二能力信息时,可以通过第二能力息指示该终端设备是否支持Row Y所示的CSI-RS资源的测量。
上述表5和表6仅仅是一种示例,本实施例中,对于接入网设备和终端设备是否支持码分多址(code-division multiple,CDM)不做限定。并且,当R为2时,则无需引入上述表5和表6。
需要说明的是,上述图3B和图3C示出的port0至port3的端口号(port0至port3分别对应的端口号为0、1、2和3)是一种相对的端口号。在实际应用中,该port0至port3的端口号可以为3000、3001、3002和3003等,具体本申请不做限定。上述图3B和图3C仅仅是为了说明第一接入网设备在不同的R个端口上发送该第二参考信号资源。
本实施例中,第二参考信号资源对应的CSI-RS有两种可能的形式,下面分别介绍:
实现方式1:步骤301中第二参考信号资源对应的CSI-RS属于已有的CSI-RS种类,该CSI-RS属于用于信道测量的CSI-RS,即(CSI-RS for channel acquisition)。也可以称该第二参考信号资源用于信道测量。
在通信协议中,若CSI-RS用于信道测量,则该CSI-RS属于一个CSI-RS resource set,且该CSI-RS resource set配置中没有repetition字段也没有trs-info字段。并且,该CSI-RS关联的上报量中包含有信道质量指示(channelquality indicator,CQI),预编码矩阵指 示符(precoding matrix indicator,PMI),CRI,层指示(layer indicator,LI),秩指示(rank indicator,RI)中的一个或多个;或者说,该CSI-RS关联的上报量中不包含RSRP或SINR。
在该实现方式1中,由于第二参考信号资源关联的上报量不包含RSRP,因此应当结合波束管流程获取该R个发送波束对应的参考信号的RSRP,具体后续结合步骤301a至步骤301c作介绍。
实现方式2:步骤301中的第二参考信号资源对应的CSI-RS是一种新的CSI-RS种类。例如,该CSI-RS用于动态发送波束合成,或者,用于发送波束合成。也可以称该第二参考信号资源用于波束合成。
具体的,该CSI-RS种类通常是通过为该CSI-RS资源或该CSI-RS所属的CSI-RS resource set新增一个字段,以标记该CSI-RS用于动态发送波束合成。例如,采用标准中ACN.1伪代码形式表示为:
DynamicBeam ENUMERATED{support}
在该实现方式2中,该第二参考信号资源关联的上报量不限定是否能够包含RSRP。因此,在该实现方式中,接入网设备可以在波束合成流程中获取该R个发送波束上的第二参考信号资源对应的参考信号的RSRP,也可以结合波束管理流程获取该R个发送波束对应的R个参考信号的RSRP,具体本申请不做限定。
本实施例中,该R个端口为接入网设备的虚拟天线端口或物理天线端口。
需要说明的是,终端设备通过同一接收波束接收该接入网设备发送的第二参考信号资源对应的参考信号。由于在步骤304中,接入网设备是基于终端设备使用同一接收波束测量得到的该R个端口的第二参考信号资源对应的参考信号的第二相位信息生成第二发送波束。因此,在终端设备侧应当对终端设备的接收波束进行限定,以便于接入网设备生成匹配终端设备与接入网设备之间的信道条件的第二发送波束,从而提高终端设备与接入网设备之间进行通信的通信性能。
302、终端设备测量该第二参考信号资源,得到第二测量信息。
该第二测量信息包括第二相位信息,该第二相位信息为该终端设备分别测量在该R个端口的第二参考信号资源得到的相位信息。
具体的,该终端设备分别测量该R个端口上第二参考信号资源对应的参考信号的第二相位信息。例如,如图3B所示,终端设备在不同类型的阴影部分的时频资源上测量该第二参考信号资源对应的参考信号,这样能够得到port0至port3分别对应第二参考信号资源对应的参考信号的相位信息。
可以理解的是,终端设备测量该第二参考信号资源,得到第二测量信息等效于终端设备测量该第二参考信号资源对应的参考信号,得到第二测量信息。
本实施例中,第二相位信息包括的内容形式为参考信号的相位,或者,不同端口之间的第二参考信号资源对应的参考信号的相位差。
一、针对第二相位信息包括参考信号的相位的方式,则第二相位信息包括R个端口的第二参考信号资源分别对应的相位。
具体的,该第二相位信息包括第二参考信号资源对应的参考信号在该R个端口上分别对应的相位。
终端设备分别测量在R个端口上的第二参考信号资源对应的参考信号的相位。然后,终端设备可以通过指示信息向接入网设备上报该在R个端口上的第二参考信号资源对应的参考信号的相位;或者,终端设备直接向接入网设备上报该在R个端口上的第二参考信号资源对应的参考信号的相位。
针对第二相位信息包括参考信号的相位的方式,终端设备需要考虑频率对第二参考信号资源对应的参考信号的相位的影响,具体上报需求请参阅前述图2A所示的实施例中步骤202的相关介绍,这里不再赘述。
二、针对第二相位信息包括不同端口之间的第二参考信号资源对应的参考信号的相位差的方式,那么第二相位信息具体包括以下任一种:
1、该R个端口的第二参考信号资源分别对应的相位之间的相位差。
具体的,该第二相位信息包括该第二参考信号资源对应的参考信号在R个端口上分别对应的相位之间的相位差。
终端设备分别测量在该R个端口上的第二参考信号资源对应的参考信号的相位;然后,终端设备计算在该R个端口上的第二参考信号资源对应的参考信号的相位之间的相位差。在该实现方式中,该第二相位信息具体包括R*(R-1)个相位差。
2、在该R个端口上的第二参考信号资源分别对应的相位分别与第二基准相位之间的相位差。
具体的,该第二相位信息包括在该R个端口上的该第二参考信号资源对应的参考信号分别对应的相位与第二基准相位之间的相位差。在该实现方式中,该第二相位信息包括R-1个相位差。
本实施例中,第二基准相位包括以下任一种可能的实现方式:
1、第二基准相位为该R个端口中端口号最小的端口的第二参考信号资源对应的相位。
具体的,该第二基准相位为在该R个端口中端口号最小的端口上的第二参考信号资源对应的参考信号的相位。例如,以该R个端口中相对端口号为0的端口上的第二参考信号资源对应的参考信号的相位为该第二基准相位。
2、第二基准相位为该R个端口中端口号最大的端口的第二参考信号资源对应的相位。
具体的,该第二基准相位为在该R个端口中端口号最大的端口上的第二参考信号资源对应的参考信号的相位。
3、第二基准相位为该R个端口中接入网设备最先发送第二参考信号资源的端口的第二参考信号资源对应的相位。
具体的,第二基准相位为在该R个端口中接入网设备最先发送第二参考信号资源对应的参考信号的端口上,该第二参考信号资源对应的参考信号的相位。
例如,如图3B所示,第二参考信号资源包括图3B所示的阴影部分的时频资源,每个端口占用的第二参考信号资源分别对应图3B所示的一种类型阴影部分的时频资源。接入网设备将在图3B上的阴影部分发送该第二参考信号资源。如图3B所示,接入网设备最先发送的 是通过port0发送承载于第11个OFDM符号的该第二参考信号资源对应的参考信号,那么接入网设备将该port0上的第二参考信号资源对应的参考信号的相位作为该第二基准相位。
4、第二基准相位为该R个端口中接入网设备最后发送第二参考信号资源的端口的第二参考信号资源对应的相位。
具体的,第二基准相位为在该R个端口中接入网设备最后发送第二参考信号资源对应的参考信号的端口上,该第二参考信号资源对应的参考信号的相位。
例如,如图3B所示,第二参考信号资源包括图3B所示的阴影部分的时频资源,每个端口占用的第二参考信号资源分别对应图3B所示的一种类型阴影部分的时频资源。接入网设备将在图3B上的阴影部分发送该第二参考信号资源。如图3B所示,接入网设备最后发送的是通过port3发送承载于第14个OFDM符号的该第二参考信号资源对应的参考信号,那么接入网设备将该port3上的第二参考信号资源对应的参考信号的相位作为该第二基准相位。
5、第二基准相位为该R个发送波束中的任一发送波束对应的端口的第二参考信号资源对应的相位。
具体的,第二基准相位为该R个发送波束中的任一发送波束对应的端口的第二参考信号资源对应的参考信号的相位。
例如,该R个发送波束中的任一发送波束可以为在波束管理过程中终端设备测量得到RSRP最大的发送波束;或者是,在步骤302的过程中,终端设备测量R个端口的第二参考信号资源对应的参考信号中RSRP最大的端口对应的发送波束。
上述示出了第二基准相位的一些可能的实现方式。在实际应用中,还可以有其他实现方式,具体本申请不做限定。
结合上述步骤301中第二参考信号资源对应的CSI-RS的实现方式2,该第二测量信息还包括该R个端口的第二参考信号资源分别对应的RSRP,即该R个发送波束对应的RSRP是终端设备按照R个端口的第二参考信号资源对应的参考信号进行测量的。
例如,如图3B所示,终端设备在不同类型的阴影部分的时频资源上测量该第二参考信号资源对应的参考信号,这样能够得到port0至port3分别对应第二参考信号资源对应的参考信号的RSRP,即该第二测量信息还包括在该R个端口的第二参考信号资源对应的参考信号的RSRP。
上述步骤302示出了终端设备测量在该R个端口的第二参考信号资源得到的第二相位信息,以及基于上述步骤301中第二参考信号资源对应的CSI-RS的实现方式2,终端设备还测量了该R个端口的第二参考信号资源分别对应的RSRP的技术方案。在实际应用中,过程1:该终端设备测量在该R个端口的第二参考信号资源得到的第二相位信息。过程2:基于上述步骤301中第二参考信号资源对应的CSI-RS的实现方式2,终端设备测量该R个端口的第二参考信号资源分别对应的RSRP。过程1和过程2可以是独立的两个测量过程;并且,终端设备测量在该R个端口的第二参考信号资源得到的第二相位信息与终端设备测量该R个端口的第二参考信号资源分别对应的RSRP的测量顺序并不做限定。
303、终端设备向接入网设备发送第二消息。
该第二消息携带第四指示信息,该第四指示信息用于指示第二相位信息。
由于已有波束管理流程中终端设备上报的N个CRI对应的RSRP的方式为:终端设备使用七比特的绝对值量化方法上报该N个CRI对应的RSRP中最大的RSRP,该N个CRI对应的RSRP中除最大的RSRP之外,都使用四比特的相对差量化方法进行上报。因此,为了匹配已有波束管理流程终端设备上报RSRP的方式,下面以该第二相位信息包括该R个端口的第二参考信号资源对应的参考信号的相位与第二基准相位之间的相位差为例介绍该第二消息携带的内容。该第二基准相位差为RSRP最大的发送波束对应的端口的第二参考信号资源对应的相位。该RSRP最大的发送波束为在波束管理流程中,该终端设备测量上报的R个RSRP中最大的RSRP对应的发送波束。
首先,先示出第二消息中用于指示每个相位差的比特位宽。具体请参阅表7:
表7
字段Field | 位宽Bitwidth |
Differential Phase | 4 |
终端设备通过四个比特向接入网设备上报该相位差Differential Phase。即每个相位差占用第二消息中的四个比特。
需要说明的是,上述表7仅仅是示例,本实施例对该Differential Phase占用的比特位宽不做限定。例如,Differential Phase占用八个比特位宽。
下面示出第二消息中上报相位差的字段顺序,请参阅表8:
表8
表7中,Differential Phase #2-#1表示CRI#1与CRI#2分别对应的CRS-RS之间的相位差,Differential Phase #3-#1表示CRI#3与CRI#1分别对应的CRS-RS之间的相位差,Differential Phase #4-#1表示CRI#4与CRI#1分别对应的CRS-RS之间的相位差。
CRI#1、CRI#2和CRI#3分别为终端设备在波束管理流程中上报的R个RSRP对应的R个参考信号资源的CRI。
对于即上述Differential Phase #2-#1、Differential Phase #3-#1和Differential Phase #4-#1分别是占用四个比特。关于相位差的量化精度,具体请参阅前述图2A所示的实施例中关于表3和表4的相关描述,这里不再赘述。
上述表7和表8仅仅是为了介绍第二消息携带的第四指示信息的具体形式,在实际应用中,终端设备上报第四指示信息也可以通过其他形式上报,并不依赖波束管理流程中RSRP的上报方式,只要接入网设备与终端设备双方预先约定好上报方式,接入网设备能够正确解析该终端设备的上报信息即可。
可选的,基于步骤301中第二参考信号资源对应的CSI-RS的实现方式2中,第二消息还携带第十一指示信息,第十一指示信息用于指示R个端口的第二参考信号资源对应的参考信 号的RSRP。
该R个端口的第二参考信号资源分别对应的RSRP可以按照端口号从大到小的顺序上报,或者,按照端口号从小到大的顺序上报。
若该R个端口的第二参考信号资源分别对应的RSRP没有全部上报或者不按照端口号顺序上报,则上述步骤302中的第二测量信息还包括该终端设备上报的RSRP分别对应的端口号。即该第二消息还携带第十四指示信息,该第十四指示信息用于指示终端设备上报的RSRP分别对应的端口号。
本实施例示出了终端设备通过指示信息的方式上报该第二相位信息的方式,从而避免信令开销过大的问题,减少资源开销。在实际应用中,该终端设备也可以直接向接入网设备上报该第二相位信息,具体本申请不做限定。
上述步骤303示出了终端设备通过同一消息(第二消息)向接入网设备发送第四指示信息、第十一指示信息和第十四指示信息的方式。在实际应用中,该第四指示信息、第十一指示信息和第十四指示信息可以分别通过不同的消息发送给接入网设备,或者,也可以是第四指示信息通过一个消息发送给接入网设备,而第十一指示信息和第十四指示信息通过另一个消息发送给接入网设备,具体本申请不做限定。后文以终端设备通过同一消息(第二消息)向接入网设备发送第四指示信息、第十一指示信息和第十四指示信息的方式为例介绍本申请实施例的技术方案。
304、接入网设备根据该第四指示信息指示的第二相位信息生成第二发送波束。
其中,第二发送波束用于该接入网设备与该终端设备之间进行通信。
本实施例中,接入网设备获取该R个发送波束分别对应的RSRP的方式包括以下两种可能的实现方式。
实现方式1、第二消息还携带第十一指示信息,该第十一指示信息用于指示该R个端口的第二参考信号资源对应的参考信号的RSRP。该接入网设备通过该第十一指示信息确定该R个端口的第二参考信号资源对应的参考信号的RSRP,并且接入网设备根据该第四指示信息确定该R个端口的第二参考信号对应的参考信号的第二相位信息。然后,接入网设备根据该R个端口的第二参考信号资源对应的参考信号的RSRP和第二相位信息生成第二发送波束。
实现方式2、接入网设备在波束管理流程中接收终端设备上报的R个参考信号资源分别对应的CRI和该R个参考信号资源对应的RSRP,该R个CRI分别与该R个发送波束一一对应。接入网设备根据该第四指示信息确定该R个端口的第二参考信号对应的参考信号的第二相位信息。然后,接入网设备根据该R个参考信号资源对应的RSRP和第二相位信息生成第二发送波束。
上述实现方式1和实现方式2中,接入网设备结合RSRP和相位信息生成第二发送波束的具体过程与前述图2A所示的实施例中的步骤204a至步骤204b类似,具体请参阅前述图2A所示的实施例中的步骤204a至步骤204b的相关介绍,这里不再赘述。
由此可知,第二发送波束的主瓣方向对准该终端设备,那么接入网设备与接入网设备通过第二发送波束进行通信传输,第二发送波束的波束增益能够大大得到提升,从而提高终端设备与接入网设备之间的通信性能。其次,相比于接入网设备从M个发送波束中选择一 个发送波束与终端设备进行通信传输的方式来说,第二发送波束对应的信道容量最大化,提升了第二发送波束对应的信道的容量。该M个发送波束为该接入网设备生成的与M个参考信号资源对应的M个发送波束,该M个发送波束为固定权值的发送波束。
可选的,第二发送波束不属于发送波束集合,该发送波束集合包括该M个发送波束。
305、接入网设备通过第二发送波束与终端设备通信。
步骤305与前述图2A所示的实施例中的步骤205类似,具体请参阅前述图2A所示的实施例中的步骤205的相关介绍,这里不再赘述。
不同的地方在于,若第二参考信号资源对应的CSI-RS为步骤301的实现方式1所示的CSI-RS,第二相位信息的上报可以与其他相关信道信息(具体包括CQI,PMI,CRI,LI,RI中的一个或多个)一起上报。第二相位信息是按照每个端口进行测量的,而其他相关信道信息可以是按照CSI-RS资源进行测量的。也就是说第二相位信息的测量作为信道测量的一部分,这样在步骤305中则无需对第二发送波束对应的信道进行测量。
本申请实施例中,终端设备测量该N个端口的第二参考信号资源的第二相位信息,并向接入网设备发送第四指示信息,以指示该第二相位信息。在终端设备的移动过程中,接入网设备与终端设备之间的信道条件是不停变化的,而R个端口分别对应接入网设备的R个发送波束。因此,第二参考信号资源的第二相位信息可以体征该接入网设备与终端设备的信道变化情况,这样接入网设备可以结合第二相位信息生成匹配终端设备与接入网设备之间的信道条件的新的发送波束,或者,从该接入网设备的R个发送波束中选择匹配终端设备与接入网设备之间的信道条件的发送波束,以提升接入网设备与终端设备之间的通信性能。
上述图3A所示的实施例中,该R个发送波束可以为在波束管理流程中,该终端设备上报的R个CRI对应的R个发送波束。那么,在该实现方式中,上述图3A所示的实施还包括步骤301a至步骤301c,且步骤301a至步骤301c在步骤301之前执行。
301a、接入网设备向终端设备发送M个参考信号资源。
步骤301a与前述图2A所示的实施例中步骤201类似,具体请参阅前述图2A所示的实施例中步骤201的相关介绍,这里不再赘述。
301b:终端设备测量M个参考信号资源,得到第三测量信息。
第三测量信息包括R个参考信号资源分别对应的RSRP和该R个参考信号资源对应的R个CRI,该R个CRI分别对应上述步骤301中的R个发送波束。
需要说明的是,终端设备接收该接入网设备发送的该R个参考信号资源对应的R个参考信号时,终端设备通过同一接收波束接收该R个参考信号,这里以终端设备通过第一接收波束接收该R个参考信号。那么可知,上述步骤301中,终端设备通过该第一接收波束接收该第二参考信号资源对应的参考信号。
可以理解的是,终端设备测量M个参考信号资源,得到第三测量信息等效于该终端设备测量该M个参考信号资源分别对应的参考信号,得到第三测量信息。
本实施例中,该M个参考信号资源中的每个参考信号资源对应一个发送波束,且不同的参考信号资源对应的发送波束相同或不同。需要说明的是,该M个参考信号资源分别对应的发送波束中应当包括至少两个不同的发送波束。
可选的,该M个参考信号资源与M个发送波束一一对应,即每个参考信号资源都有对应发送波束,且不同参考信号资源对应不同的发送波束。在步骤301b中以该R个参考信号资源对应的R个发送波束不相同。
301c:终端设备向接入网设备发送第三消息,该第三消息携带第五指示信息和第六指示信息。
该第五指示信息用于指示R个参考信号资源分别对应的CRI,该第六指示信息用于指示该R个参考信号资源分别对应的RSRP。
具体的,接入网设备根据该第五指示信息和该第六指示信息确定该R个参考信号资源分别对应的RSRP。
需要说明的是,上述步骤301c以终端设备通过指示信息向接入网设备上报R个参考信号资源分别对应的RSRP的方式为例进行说明。在实际应用中,该终端设备可以直接向该接入网设备上报该R个参考信号资源分别对应的RSRP,具体本申请不做限定。
步骤301c以终端设备通过同一消息(第三消息)向接入网设备发送给第五指示信息和第六指示信息的方式为例介绍本申请实施例的技术方案。在实际应用中,该终端设备也可以通过不同的消息分别发送第五指示信息和第六指示信息,具体本申请不做限定。
上述步骤301a至步骤301c可以是周期性执行的,也可以是非周期性执行,具体本申请不做限定。针对终端设备每次上报的R个CRI,终端设备使用相同的接收波束接收该R个CRI分别对应的参考信号。
可选的,步骤301至步骤303周期性执行、非周期执行或者半持续执行。因此,接入网设备在选择该R个发送波束时,接入网设备可以先选择在波束管理流程中终端设备最近一次上报的R个CRI对应的R个发送波束,接入网设备再执行步骤301至步骤303。
本申请实施例中,若接入网设备配置该终端设备在该接入网设备的P个端口接收该第二参考信号资源,但是接入网设备通过波束管理流程确定终端设备上报的P个发送波束中只有R个发送波束适合新的发送波束。则在该可能的情况下,上述图3A所示的实施例还包括步骤301d和步骤301e,且步骤301d和步骤301e在步骤301之前执行。
步骤301d:接入网设备向终端设备发送第七指示信息。
该第七指示信息用于指示该终端设备对该接入网设备的R个端口的第二参考信号资源的第二相位信息进行测量。
该R个端口为该接入网设备中的P个端口中的前R个端口、或后R个端口、或任R个端口,具体本申请不做限定。该P个端口为该接入网设备中已被配置的用于发送第二参考信号资源的端口。P为大于2的整数,P大于R。即接入网设备通过第七指示信息指示:终端设备在指定的端口(该R个端口)进行第二参考信号资源的测量。例如,如图3B所示,接入网设备指示终端设备在port0和port2接收第二参考信号资源。
具体的,该接入网设备可以通过媒体接入控制(media access control element,MAC CE)或下行控制信息(downlink control information,DCI)向终端设备发送该第七指示信息。
步骤301e:终端设备根据该第七指示信息确定对该接入网设备的R个端口的第二参考信号资源进行测量。
为了接入网设备为终端设备配置合适的资源配置和上报方式,以便于接入网设备正确解析终端设备的上报量。可选的,上述图3A所示的实施例还包括步骤306和步骤307,且步骤306和步骤307在步骤301之前执行。
306、终端设备向接入网设备发送该终端设备的第二能力信息。
该第二能力信息携带第八指示信息,该第八指示信息的指示形式包括以下任一种:
1、该第八指示信息用于指示该终端设备是否支持参考信号发送模式;
该参考信号发送模式为:接入网设备通过R个发送波束并通过接入网设备的R个端口在时域上连续的R个符号发送第二参考信号资源对应的参考信号。该R个发送波束与该R个端口一一对应,该R个端口与该R个符号一一对应。
例如,如图3A所示,接入网设备包括port0至port3。port0对应发送波束1,port1对应发送波束2,port3对应发送波束3,port4对应发送波束4。接入网设备通过port0、port1、port2和port3和通过发送波束1、发送波束2、发送波束3和发送波束4发送第二参考信号资源。即该port0至port4都用于发送第二参考信号资源,且在时域上连续跨四个OFDM符号发送第二参考信号资源(具体为图3A中阴影的部分时频资源),每个符号对应一个端口。即接入网设备通过R个端口发送同一参考信号。
2、该第八指示信息用于指示该终端设备是否支持Row X所示的参考信号资源的测量。Row X的相关介绍请参阅前述步骤301中的表4或表5。
3、该第八指示信息用于指示该终端设备支持连续测量参考信号的最大符号数。
可选的,第二能力信息还携带终端设备支持连续测量参考信号的最大符号数。
具体的,终端设备可以通过以下标准中ACN.1伪代码形式通知该接入网设备终端设备支持测量跨3个连续符号的CSI-RS。
MaxNrOfSymbols-CSI-RS ENUMERATED{3}
上述步骤306示出了终端设备通过第二能力信息上报第八指示信息的方式,在实际应用中,该终端设备也可以单独向该接入网设备发送该第八指示信息,或者,该终端设备也可以通过其他信息或消息携带该第八指示信息并上报给接入网设备,具体本申请不做限定。
307、接入网设备向终端设备发送第二配置信息。
该第二配置信息用于配置该第二参考信号资源用于波束合成和配置终端设备上报R个端口的第二参考信号资源的第二相位信息。
一种可能的实现方式中,基于步骤301中的实现方式1所示的第二参考信号资源对应的CSI-RS中,在步骤307的配置过程之前,接入网设备为该终端设备配置的用于波束管理的配置。例如,该用于波束管理的配置为ResourceConfig#1。用于波束管理的第一资源集合包括16个CSI-RS,接入网设备要求终端设备上报的上报量为CRI-RSRP,上报数目(nrofReportedRs)为4。
下面基于上述用于波束管理的配置的基础上,结合图3D示出第二配置信息的一种可能的实现方式。该第二配置信息包括上报量Differential Phase和信道测量ResourceConfig#2。其中,ResourceConfig#2包括的resource#20中配置有用于波束合成的端口数、各个端口对应的时频资源位置等信息。该接入网设备上配置的用于波束合成的端 口的数目小于波束管理上报的发送波束数目nrofReportedRs。
具体的,接入网设备可以结合图3B和表4配置该resource#20,或者结合图3C和表5配置该resource#20,主要是配置用于波束合成的端口数,各个端口对应的时频位置。
在图3D所示的第二配置信息中,第二相位信息是通过波束合成过程上报的,而R个发送波束对应的R个参考信号的RSRP可以是在波束管理流程中上报的。那么,在该可能的实现方式中,第二配置信息中的resource#20与ResourceConfig#1关联。即在上述步骤301中,终端设备应当使用波束管理过程中用于接收该R个发送波束对应的R个参考信号的接收波束来接收该第二参考信号资源。
另一种可能的实现方式中,基于步骤301的实现方式2所示的第二参考信号资源对应的CSI-RS中,第二相位信息可以结合CRS-RSRP一起上报,即第二相位信息和CRI-RSRP都是按照port进行测量的。则第二配置信息与图3C类似,不同的地方在于,在该实现方式中,该第二配置信息包括的上报量为CRI-RSRP-DifferentialPhase和信道测量ResourceConfig#2。
上述步骤301至步骤304可以周期性重复执行,也可以是非周期执行,或者还可以半持续执行,具体本申请不做限定。
若步骤301至步骤304周期性重复执行,则接入网设备通过第二配置信息将步骤301至步骤304配置为周期性重复执行。若步骤301至步骤304为非周期执行,则接入网设备在前述步骤301c之后,步骤301之前,按照需求触发步骤301至步骤304的执行。若步骤301至步骤304为半持续执行,接入网设备在前述步骤301c之后,步骤301之前,先执行激活、去激活和触发等操作,然后再执行步骤301至步骤304。接入网设备配置用于步骤301至步骤304的非周期执行的资源或用于步骤301至步骤304的半持续执行的资源,以及对应的上报方式可以参阅现有配置方式,具体本申请不做限定。
308、终端设备根据第二配置信息确定:该第二参考信号资源用于波束合成以及上报该接入网设备的R个端口的第二参考信号资源的第二相位信息。
基于步骤301中的实现方式1所示的第二参考信号资源对应的CSI-RS中,可选的,终端设备根据第二配置信息确定第二配置信息的resource#20与用于波束管理的配置ResourceConfig#1关联。然后,终端设备确定在波束管理流程中用于接收终端设备上报的R个参考信号的接收波束,并通过该接收波束接收第二参考信号资源。
本申请实施例中,终端设备测量该N个端口的第二参考信号资源的第二相位信息,并向接入网设备发送第四指示信息,以指示该第二相位信息。在终端设备的移动过程中,接入网设备与终端设备之间的信道条件是不停变化的,而R个端口分别对应接入网设备的R个发送波束。因此,第二参考信号资源的第二相位信息可以体征该接入网设备与终端设备的信道变化情况,这样接入网设备可以结合第二相位信息生成匹配终端设备与接入网设备之间的信道条件的新的发送波束,或者,从该接入网设备的R个发送波束中选择匹配匹配终端设备与接入网设备之间的信道条件的发送波束,以提升接入网设备与终端设备之间的通信性能。
需要说明的是,上述图2A所示的实施例和图3A所示的实施例中,接入网设备通过终端 设备与接入网设备之间的下行测量获取参考信号的相位信息和幅度信息,从而生成匹配终端设备与接入网设备之间的信道条件的发送波束。
在实际应用中,接入网设备也可以通过终端设备与接入网设备之间的上行测量获取参考信号的相位信息和幅度信息,从而生成匹配终端设备与接入网设备之间的信道条件的发送波束。例如,终端设备向接入网设备发送探测参考信号(sounding reference signal,SRS);然后,接入网设备测量该SRS,得到该SRS的相位信息和幅度信息。具体包括以下两种可能的实现方式:
1、终端设备向接入网设备发送SRS,由接入网设备对该SRS进行测量,即上行测量。接入网设备再根据测量结果生成匹配终端设备与接入网设备之间的信道条件的发送波束,具体的生成方式请参阅前述图2A所示的实施例中的步骤204a至步骤204b。在该实现方式中,由接入网设备为该SRS配置合适的资源,无需额外增加接入网设备与终端设备之间的信息交互。
2、终端设备向接入网设备发送SRS,由接入网设备对该SRS测量,即上行测量。接入网设备向终端设备发送测量结果,再由终端设备计算合成权。然后,终端设备向接入网设备反馈合成权,再由接入网设备根据合成权生成匹配终端设备与接入网设备之间的信道条件的发送波束,具体的生成方式请参阅前述图2A所示的实施例中的步骤204a至步骤204b。
