相关申请的交叉引用
本申请要求在2022年09月20日提交中国专利局、申请号为202211146466.3、申请名称为“一种波束确定的方法和装置”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
本申请涉及通信技术领域，尤其涉及一种波束确定的方法和装置。
背景技术
毫米波因拥有频率资源丰富/带宽极大、易与波束赋形技术结合、可实现极低时延、可支持密集化部署、可进行高精度定位、集成度高的技术优势，而成为通信领域的核心技术之一。通常毫米波由于采用混合波束成型(hybrid beamforming，HBF)架构，可以通过改变移向器生成模拟波束，定向接收一定区域的终端信号，然后每个时隙Slot通过模拟加权，发送或接收一定覆盖范围内的用户信号，通过时分调度，完成整个扇区的覆盖。例如毫米波基站基于HBF架构，先由移向器生成模拟波束，再叠加预编码矩阵指示(precoding matrix indicator，PMI)数字权，进而与终端设备进行通信。
在毫米波的使用过程中，若将波束设计的比较窄，会使得波束覆盖的距离更长，但是使用波束的数量会增加，导致系统开销增大，且由于终端设备能扫描的波束有限，使用波束的数量过多，会超出终端设备扫描波束的能力；若将波束设计的比较宽，虽波束使用的数量会减少，但是波束覆盖的距离会减短。因此，如何确定合适的通信波束以兼顾波束的开销和覆盖距离是目前亟需解决的技术问题。
发明内容

在本申请方案中，网络设备获取第一宽波束的测量信息，然后根据该第一宽波束的测量信息，确定使用该第一宽波束或第一窄波束与终端设备进行通信。由于宽波束的覆盖范围广且产生开销少，窄波束的覆盖距离远能保证较远终端设备的通信，因此，本申请方案中的网络设备可以先使用宽波束与终端设备进行通信并获得该宽波束的测量结果，进而再依据该宽波束的测量结果确定是继续选择该宽波束与该终端设备进行通信，还是选择新的窄波束与该终端设备进行通信，从而在兼顾波束开销和覆盖距离的情况下，确定合适的波束与终端设备进行通信，既可保证通信的有效性，也可减少系统的开销。
在一种实施方式中，该网络设备获取第一宽波束的测量信息，包括：该网络设备使用该第一宽波束向该终端设备发送下行参考信号；该网络设备从该终端设备接收该第一宽波束的下行参考信号接收功率RSRP。
通过该实施方式，网络设备可以有效地获得第一宽波束的下行参考信号接收功率RSRP，将该第一宽波束的下行参考信号接收功率RSRP视为该第一宽波束的测量信息，可以用于判断终端设备的远近点位置，同时也可以作为后续网络设备判断该第一宽波束是否可继续被使用的一个依据。
在一种实施方式中，该网络设备根据该第一宽波束的测量信息，确定使用该第一宽波束或第一窄波束与终端设备进行通信，包括：若该第一宽波束的下行RSRP大于或等于预设的下行RSRP阈值时，该网 络设备确定使用该第一宽波束与该终端设备进行通信；或者若该第一宽波束的下行RSRP小于预设的下行RSRP阈值时，该网络设备确定使用该第一窄波束与该终端设备进行通信。

具体实施方式
下面将结合本申请实施例中的附图，对本申请实施例中的技术方案进行描述。
图1为本申请实施例应用的通信系统的架构示意图。如图1所示，通信系统1000包括网络设备100和核心网200，可选的，通信系统1000还可以包括互联网300。其中，网络设备100可以包括至少一个网络设备，如图1中的110a和110b，还可以包括至少一个终端设备，如图1中的120a-120j。其中，110a是基站，110b是微站，120a、120e、120f和120j是手机，120b是汽车，120c是加油机，120d是布置在室内或室外的家庭接入节点(home access point，HAP)，120g是笔记本电脑，120h是打印机，120i是无人机。
图1中，终端设备可以与网络设备相连，网络设备可以与核心网中的核心网设备连接。核心网设备与网络设备可以是独立的不同的物理设备，也可以是将核心网设备的功能与网络设备的逻辑功能集成在同一个物理设备上，还可以是一个物理设备上集成了部分核心网设备的功能和部分的无线网络设备的功能。终端设备和终端设备之间以及网络设备和网络设备之间可以通过有线或无线的方式相互连接。图1只是示意图，该通信系统中还可以包括其它设备，如还可以包括无线中继设备和无线回传设备，在图1 中未画出。
下面对核心网设备、网络设备和终端设备进行介绍。
(1)核心网设备
核心网设备位于移动通信网络中的核心网中的网络设备，用于实现核心网的功能。
通常，按照逻辑功能划分，核心网可以划分为控制面和用户面。其中，核心网中负责控制面功能网元可以统称为控制面网元，负责用户面功能的网元可以统称为用户面网元。在本申请实施例中，涉及的核心网设备主要为控制面网元，例如，接入和移动性管理功能(access and mobility management function，AMF)。
(2)网络设备
网络设备，为无线接入网(radio access network，RAN)中的节点，又可以称为基站，还可以称为RAN节点(或设备)。一些网络设备的举例为：下一代基站(next generation nodeB，gNB)、下一代演进的基站(next generation evolved nodeB，Ng-eNB)、传输接收点(transmission reception point，TRP)、演进型节点B(evolved Node B，eNB)、无线网络控制器(radio network controller，RNC)、节点B(Node B，NB)、基站控制器(base station controller，BSC)、基站收发台(base transceiver station，BTS)、家庭基站(例如，home evolved NodeB，或home Node B，HNB)、基带单元(base band unit，BBU)，或无线保真(wireless fidelity，Wifi)接入点(access point，AP)，网络设备还可以是卫星，卫星还可以称为高空平台、高空飞行器、或卫星基站。网络设备还可以是其他具有网络设备功能的设备，例如，网络设备还可以是设备到设备(device to device，D2D)通信中担任网络设备功能的设备。网络设备还可以是未来可能的通信系统中的网络设备。
在一些部署中，网络设备可以包括集中式单元(centralized unit，CU)和(distributed unit，DU)。网络设备还可以包括有源天线单元(active antenna unit，AAU)。CU实现网络设备的部分功能，DU实现网络设备的部分功能，比如，CU负责处理非实时协议和服务，实现无线资源控制(radio resource control，RRC)，分组数据汇聚层协议(packet data convergence protocol，PDCP)层的功能。DU负责处理物理层协议和实时服务，实现无线链路控制(radio link control，RLC)层、媒体接入控制(media access control，MAC)层和物理(physical，PHY)层的功能。AAU实现部分物理层处理功能、射频处理及有源天线的相关功能。由于RRC层的信息最终会变成PHY层的信息，或者，由PHY层的信息转变而来，因而，在这种架构下，高层信令，如RRC层信令，也可以认为是由DU发送的，或者，由DU+AAU发送的。可以理解的是，网络设备可以为包括CU节点、DU节点、AAU节点中一项或多项的设备。此外，可以将CU划分为RAN中的网络设备，也可以将CU划分为核心网(core network，CN)中的网络设备，本申请对此不做限定。
本申请实施例中，用于实现网络设备的功能的装置可以是网络设备，也可以是能够支持网络设备实现该功能的装置，例如芯片系统，该装置可以被安装在网络设备中。其中，芯片系统可以由芯片构成，也可以包括芯片和其他分立器件。在本申请实施例提供的技术方案中，以用于实现网络设备的功能的装置是网络设备为例，描述本申请实施例提供的技术方案。
(3)终端设备
终端设备也可以称为终端、用户设备(user equipment，UE)、移动台、移动终端等。终端设备可以广泛应用于各种场景，例如，设备到设备(device-to-device，D2D)、车物(vehicle to everything，V2X)通信、机器类通信(machine-type communication，MTC)、物联网(internet of things，IOT)、虚拟现实、增强现实、工业控制、自动驾驶、远程医疗、智能电网、智能家具、智能办公、智能穿戴、智能交通、智慧城市等。终端设备可以是手机、平板电脑、带无线收发功能的电脑、可穿戴设备、车辆、无人机、直升机、飞机、轮船、机器人、机械臂、智能家居设备等。本申请实施例对终端设备所采用的具体技术和具体设备形态不做限定。
本申请实施例中，用于实现终端设备的功能的装置可以是终端设备；也可以是能够支持终端设备实现该功能的装置，例如芯片系统，该装置可以被安装在终端设备中。本申请实施例提供的技术方案中，以用于实现终端设备的功能的装置是终端设备为例，描述本申请实施例提供的技术方案。
此外，同一个终端设备或网络设备，在不同应用场景中可以提供不同的功能。比如，图1中的手机包括120a、120e、120f和120j。其中，手机120a可以接入基站110a，连接汽车120b，与手机120e直连通信以及接入到HAP；手机120e可以接入HAP以及与手机120a直连通信；手机120f可以接入为微 站110b，连接笔记本电脑120g，连接打印机120h；手机120j可以控制无人机120i。
网络设备和终端设备的角色可以是相对的。例如，图1中的直升机或无人机120i可以被配置成移动基站，对于那些通过120i接入到网络设备100的终端设备120j来说，终端设备120i是基站；但对于基站110a来说，120i是终端设备，即110a与120i之间是通过无线空口协议进行通信的。当然，110a与120i之间也可以是通过基站与基站之间的接口协议进行通信的，此时，相对于110a来说，120i也是基站。因此，网络设备和终端设备都可以统一称为通信装置，图1中的110a和110b可以称为具有基站功能的通信装置，图1中的120a-120j可以称为具有终端设备功能的通信装置。
网络设备和终端设备可以是固定位置的，也可以是可移动的。网络设备和终端设备可以部署在陆地上，包括室内或室外、手持或车载；也可以部署在水面上；还可以部署在空中的飞机、气球和人造卫星上。本申请的实施例对网络设备和终端设备的应用场景不做限定。
网络设备和终端设备之间、网络设备和网络设备之间、终端设备和终端设备之间可以通过授权频谱(licensed spectrum)进行通信，也可以通过免授权频谱(unlicensed spectrum)进行通信，也可以同时通过授权频谱和免授权频谱进行通信；可以通过6千兆赫兹(gigahertz，GHz)以下的频谱进行通信，也可以通过6GHz以上的频谱进行通信，还可以同时使用6GHz以下的频谱和6GHz以上的频谱进行通信。本申请的实施例对无线通信所使用的频谱资源不做限定。
本申请实施例所提出的一种波束的确定方法所使用的波束可以为毫米波，为了更好的理解本申请实施例方案，下面对毫米波以及毫米波的运用进行相关介绍。
通常，毫米波由于采用混合波束成型HBF架构，通过改变移向器生成模拟波束，定向接收一定区域的终端信号。每个时隙Slot通过模拟加权，发送或接收一定覆盖范围内的用户信号，通过时分调度，完成整个扇区的覆盖，如图2A所示，基站发送的每个波束可以覆盖一定区域，所有波束时分覆盖扇区范围，基站可以与位于该扇区范围内的终端设备进行通信。
目前毫米波最优波束测量流程中，如图2B所示，包括：步骤1、基站周期性下发信道状态信息(channel state information，CSI)波束(即下行CSI波束)，相应的，终端设备通过周期性扫描基站下发的CSI波束；步骤2、终端设备测量服务SSB波束对应的下行CSI波束；步骤3、终端设备向基站上报服务SSB波束对应的下行CSI波束的测量结果，相应的，基站接收来自终端设备的该测量结果；步骤4、基站根据终端设备上报的该测量结果，为该终端设备确定合适的下行服务CSI波束；步骤5、基站使用该下行服务CSI波束与该终端设备进行下行业务的发送。
示例性地，在上述步骤2至步骤5中，终端设备可以通过测量基站的下行CSI波束的参考信号接收功率(Reference Signal Receiving Power，RSRP)，将其中RSRP最高的至少一个CSI波束(Beam)上报给基站，基站从该至少一个CSI波束中为该终端设备选择合适的下行服务CSI波束，并使用该下行服务CSI波束与该终端设备进行下行业务的通信。
基于上述波束测量的场景中，如图2C中(a)所示，如果波束设计的较宽，虽然能减少使用波束个数，但相应波束覆盖距离会变小。如图2C中(b)所示，如果波束设计的较窄，虽然波束的覆盖距离会变大，但相应使用波束个数会变多，从而导致测量开销变大，而且终端设备能扫描的波束有限，如果使用波束个数过多，则会超出终端设备扫描测量能力；因此，在该场景中无法兼顾测量开销和波束的覆盖距离。
鉴于此，本申请提出一种波束确定的方法，该方法可以兼顾开销和波束覆盖距离，在尽量小的开销下，保障远点终端设备的覆盖。
本申请实施例可以应用于毫米波通信系统中，例如NR通信系统、或者其它通信系统中，如未来移动通信系统(如6G通信系统)等。示例性的，如上述图1所示。
应理解，上述图1所示的通信系统的网络架构仅为一个举例，并不对本申请实施例中的通信系统的网络架构构成限定。本申请实施例不限定通信系统中网络设备的个数、终端设备的个数。示例的，当本申请实施例的通信系统中包括多个网络设备时，网络设备与网络设备之间可以进行多点协同通信。例如，通信系统中包括多个宏基站、多个微基站，其中，宏基站与宏基站、微基站与微基站、宏基站与微基站间可以进行多点协同通信。
以下对本申请实施例涉及的部分用语进行解释，以便于本领域技术人员理解。
1)、波束：波束是一种通信资源，波束可以是宽波束，也可以是窄波束，或其它类型的波束。形成 波束的技术可以是波束成形技术或其它技术手段。波束成形技术可具体为数字波束成形技术、模拟波束成形技术、混合数字/模拟波束成形技术等。不同的波束可认为是不同的通信资源，通过不同的波束可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通信特征的多个波束视为一个波束，一个波束可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，发送波束可以是指信号经天线发射出去后在空间不同方向上形成的信号强度分布，接收波束可以是指从天线上接收到的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，波束还可以称为空域滤波器(spatial filer)，发送波束也可称为空域发送滤波器，接收波束也可称为空域接收滤波器。
此外，本申请实施例中终端和网络设备之间是通过波束接收或发送信号的。具体的，波束可以按照信号接收或发送的方向，划分为接收波束和发送波束。其中，接收波束用于接收信号，发送波束用于发送信号。例如，网络设备使用发送波束发送下行信号，而终端设备使用接收波束接收下行信号。再例如，终端设备使用发送波束发送上行信号，网络设备使用接收波束接收上行信号。而终端设备使用的发送波束、和网络设备使用的接收波束组成一个波束对，终端设备使用的接收波束、网络设备使用的发送波束也组成一个波束对。
需要说明的是，对于终端设备来说，接收波束又可以称之为下行波束，发送波束又可以称之为上行波束。终端设备接收下行信号所使用的接收波束还可以称之为下行工作波束，终端设备发送上行信号所使用的发送波束还可以称之为上行工作波束。在终端设备支持波束互易能力的情况下，终端设备可以基于下行工作波束，确定上行工作波束，或者，基于上行工作波束，确定下行工作波束。
此外，在本申请实施例中，毫米波基站基于混合波束成型HBF架构，先由移向器生成模拟波束在叠加预编码矩阵指示PMI数字权以实现覆盖和通信。
2)、SSB：5G NR引入了同步信号/物理广播信道块(synchronization system/physical broadcast channel block，SS/PBCH block)，SS/PBCH block可以简称为SSB。网络设备在一个周期中以扫描的方式发送多个SSB，不同的SSB对应不同的空间方向(例如对应不同的波束)。SSB的数量由网络设备通过系统消息配置给终端，NR支持4、8、64三种SSB数量。通常情况下，频点越高，SSB数量越多，发送SSB的波束越窄。
在随机接入过程中，终端对网络设备发送的SSB，测量参考信号接收功率(reference signal receiving power，RSRP)，当某个SSB的RSRP测量结果大于或等于预设门限时，终端可以选择该SSB所映射的随机接入资源执行随机接入(random access channel，RACH)过程。
3)、下行参考信号：本申请实施例中下行参考信号为网络设备发送给终端设备的参考信号(reference signal，RS)。下行参考信号可以包括信道状态参考信号(channel state information reference signal，CSI-RS)、同步信号块SSB、探测参考信号(sounding reference signal，SRS)、解调参考信号(demodulation reference signal，DMRS)等。其中，不同的通信过程中，终端接收的下行参考信号可以是不同的。例如，在随机接入过程中，终端接收的下行参考信号为SSB。再例如，终端在接入网络设备后，在波束追踪过程中，接收的下行参考信号为CSI-RS。具体的，终端可以周期性、和/或通过事件触发接收下行参考信号。
需要注意的是，以下实施例中所使用的术语只是为了描述特定实施例的目的，而并非旨在作为对本申请的限制。如在本申请的说明书和所附权利要求书中所使用的那样，单数表达形式“一个”、“一种”、“所述”、“上述”、“该”和“这一”旨在也包括例如“一个或多个”这种表达形式，除非其上下文中明确地有相反指示。还应当理解，在本申请实施例中，“一个或多个”是指一个、两个或两个以上；“和/或”，描述关联对象的关联关系，表示可以存在三种关系；例如，A和/或B，可以表示：单独存在A，同时存在A和B，单独存在B的情况，其中A、B可以是单数或者复数。字符“/”一般表示前后关联对象是一种“或”的关系。
在本说明书中描述的参考“一个实施例”或“一些实施例”等意味着在本申请的一个或多个实施例中包括结合该实施例描述的特定特征、结构或特点。由此，在本说明书中的不同之处出现的语句“在一个实施例中”、“在一些实施例中”、“在其他一些实施例中”、“在另外一些实施例中”等不是必然都参考相同的实施例，而是意味着“一个或多个但不是所有的实施例”，除非是以其他方式另外特别强调。术语“包括”、“包含”、“具有”及它们的变形都意味着“包括但不限于”，除非是以其他方式另外特别强调。
在本申请实施例的描述中，本申请实施例涉及的多个，是指大于或等于两个。
此外，在本申请中，“指示”可以包括直接指示、间接指示、显示指示、隐式指示。当描述某一指示信息用于指示A时，可以理解为该指示信息携带A、直接指示A，或间接指示A。
本申请中，指示信息所指示的信息，称为待指示信息。在具体实现过程中，对待指示信息进行指示的方式有很多种，例如但不限于，可以直接指示待指示信息，如待指示信息本身或者该待指示信息的索引等。也可以通过指示其他信息来间接指示待指示信息，其中该其他信息与待指示信息之间存在关联关系。还可以仅仅指示待指示信息的一部分，而待指示信息的其他部分则是已知的或者提前约定的。例如，还可以借助预先约定(例如协议规定)的各个信息的排列顺序来实现对特定信息的指示，从而在一定程度上降低指示开销。
待指示信息可以作为一个整体一起发送，也可以分成多个子信息分开发送，而且这些子信息的发送周期和/或发送时机可以相同，也可以不同。具体发送方法本申请不进行限定。其中，这些子信息的发送周期和/或发送时机可以是预先定义的，例如根据协议预先定义的，也可以是发射端设备通过向接收端设备发送配置信息来配置的。其中，该配置信息可以例如但不限于包括无线资源控制信令、媒体接入控制MAC层信令和物理层信令中的一种或者至少两种的组合。其中，无线资源控制信令例如包无线资源控制RRC信令；MAC层信令例如包括MAC控制元素(control element，CE)；物理层信令例如包括下行控制信息DCI。
下面结合具体实施例介绍本申请的技术方案。
本申请实施例提供了一种波束确定的方法，该方法可适用于但不限于图1的通信系统架构，并且该方法可以由终端设备(也可以是网络设备)的收发器和/或处理器执行，也可以由该收发器和/或处理器对应的芯片执行。或者该实施例还可由该终端设备(也可以是网络设备)所连接的控制器或控制设备实现，该控制器或控制设备用于管理包括该终端设备(也可以是网络设备)在内的至少一个装置。并且针对执行该实施例的通信装置的具体形态，本申请不做具体限定。并且下文中提及的“第一”、“第二”等序数词是用于对多个对象进行区分，以便于描述，并不用于限定多个对象的顺序、时序、优先级或者重要程度。请参阅图3，该方法的具体流程如下：

综上，在本申请方案中，网络设备获取第一宽波束的测量信息，然后根据该第一宽波束的测量信息，确定使用该第一宽波束或第一窄波束与终端设备进行通信。由于宽波束的覆盖范围广且产生开销少，窄波束的覆盖距离远能保证较远终端设备的通信，因此，本申请方案中的网络设备可以先使用宽波束与终端设备进行通信并获得该宽波束的测量结果，进而再依据该宽波束的测量结果确定是继续选择该宽波束与终端设备进行通信，还是选择新的窄波束与终端设备进行通信，从而在兼顾波束开销和覆盖距离的情况下，确定合适的波束与终端设备进行通信，既可以保证通信的有效性，也可以减少系统的开销。
下面针对上述图3所示本申请实施例提出的一种波束确定的方法，通过具体实施例进一步详细阐述。
具体实施例一
在该具体实施例一，主要针对网络设备如何确定合适的下行波束，以与终端设备进行下行通信，该网络设备以基站为例，如图4所示，该具体实施例一的流程如下：
S401：基站使用宽波束发送下行参考信号。
在该步骤S401中，基站使用一个或多个宽波束(也可以称为基线波束)发送对应的下行参考信号。
示例性地，该下行参考信号可以探测参考信号SRS或信道状态信息参考信号CSI-RS等。
例如，基站分别使用宽波束0、宽波束1、宽波束2发送下行CSI-RS。
S402：终端设备对宽波束进行扫描，并测量得到宽波束的下行参考信号接收功率RSRP。
在该步骤S402中，终端设备扫描基站的一个或多个宽波束，终端设备可能扫描到其中至少一个宽波束，通过扫描到的该至少一个宽波束分别接收到对应的下行参考信号，并基于每个宽波束所接收的下行参考信号测量得到每个宽波束的下行RSRP，进而从中确定下行RSRP最大的宽波束。
例如，基站分别使用宽波束0、宽波束1、宽波束2发送下行参考信号，终端设备能扫描到宽波束0和宽波束1，分别通过宽波束0和宽波束1接收来自基站的下行参考信号；然后，终端设备基于宽波束0的下行参考信号测量得到宽波束0的RSRP值，基于宽波束1的下行参考信号测量得到宽波束1的RSRP值，且宽波束1的RSRP值大于宽波束0的RSRP值。
S403：终端设备向基站上报最优波束的下行RSRP。
相应的，基站接收该最优宽波束的下行RSRP。
例如，若终端设备确定宽波束1的RSRP值大于宽波束0的RSRP值，则终端设备将宽波束1视为最优宽波束，并向基站上报宽波束1的RSRP值。
S404：基站根据终端设备上报的最优波束的下行RSRP，确定该终端设备的位置。
在该步骤S404中，若终端设备上报的最优波束的下行RSRP大于或等于预设的下行RSRP阈值时，基站确定该终端设备处于近点位置(中近点)，若终端设备上报的最优波束的下行RSRP小于预设的下行RSRP阈值时，基站确定该终端设备处于远点位置(远点)。
例如，若终端设备上报的宽波束1的下行RSRP值大于或等于预设的下行RSRP阈值，则基站确定该终端设备处于近点位置；若终端设备上报的宽波束1的下行RSRP值小于预设的下行RSRP阈值，则基站确定该终端设备处于远点位置。
通过上述步骤S401-S404，基站可以初步判定终端设备的位置，进而可以依据终端设备的位置，确定合适的波束，用于基站与该终端设备之间的下行通信。
S405：基站根据终端设备的位置，确定与该终端设备进行通信的波束。
在执行该步骤S405时，可能包括以下两种情况：
情况1：若通过上述步骤S404，基站确定终端设备处于近点位置时，则在该步骤S405中基站继续使用上述终端设备上报的最优宽波束与该终端设备进行下行通信(或传输)，不再执行下述步骤S406-S408。
情况2：若通过上述步骤S404，基站确定终端设备处于远点位置时，说明上述终端设备上报的最优宽波束的覆盖不足，会导致终端设备的下行业务较差，因此，基站继续通过下述步骤S406-S408确定合适的波束，以用于与终端设备进行下行业务通信。
例如，若终端设备上报的宽波束1的下行RSRP值大于或等于预设的下行RSRP阈值，则基站确定终端设备处于近点位置，基站确定使用宽波束1与该终端设备进行下行业务通信。若终端设备上报的宽波束1的下行RSRP值小于预设的下行RSRP阈值，则基站确定终端设备处于远点位置，基站不使用宽波束1与该终端设备进行下行业务通信，继续通过下述步骤S406-S408确定合适的波束。
S406：基站在宽波束的覆盖范围内，使用至少一个窄波束向终端设备发送下行信号。
相应的，终端设备分别通过该至少一个窄波束接收来自基站的下行信号。
该步骤S406中的下行信号也可以通信信号、广播信号，也可以为下行参考信号，本申请对该下行信号的类型不做具体限定。当其为下行参考信号时，其类型与上述步骤S401的下行参考信号的类型可以相同或者不同，本申请实施例对此不做限定。
示例性地，该下行信号为SRS或CSI-RS。
基于上述步骤S405，若基站确定终端设备处于远点位置，则基站在终端设备上报的最优RSRP对应的宽波束的覆盖范围内，下行遍历尝试更窄的波束向终端设备发送下行信号。
在本申请实施例中，所述下行遍历可以理解为依次尝试使用各种更窄的波束(可统称为窄波束)向终端设备发送下行信号。这些窄波束的覆盖角度和覆盖距离、以及覆盖方向均不同；或者部分窄波束的覆盖方向相同，覆盖角度和覆盖距离不同；又或者部分窄波束的覆盖角度和覆盖距离相同，覆盖方向不相同，本申请实施例对此不做具体限定。
例如，基站在宽波束1的覆盖范围(或角度)内，分别尝试使用窄波束0、窄波束1、窄波束2、窄波束3分别向终端设备发送下行信号。这些窄波束的覆盖角度和覆盖距离(长度)均不同，窄波束0的覆盖角度>(大于)窄波束1的覆盖角度>(大于)窄波束2的覆盖角度>(大于)窄波束3的覆盖角度。
通常波束的覆盖角度越小，则该波束的覆盖距离越远；波束的覆盖角度越大，则该波束的覆盖距离越短。
S407：终端设备基于通过该至少一个窄波束所接收的下行信号，生成该至少一个窄波束的反馈信息，并向基站上报该至少一个窄波束的反馈信息。
在该步骤S407中，可以通过但不限于以下两种方法确定该至少一个窄波束的反馈信息：
方法1
方法1为基站可以根据至少一个窄波束的下行RSRP，确定与终端设备进行上行通信使用的窄波束。基于该方式1，又可以包括但不限于以下两种执行方式：
执行方式一：基站可以先使用一个窄波束向终端设备发送下行信号，终端设备基于该窄波束接收到 的下行信号测量得到该窄波束的下行RSRP，并上报给基站。
基站接收到终端设备上报的窄波束的RSRP，若该窄波束的RSRP不小于目标RSRP，说明该终端设备通过该窄波束接收基站的下行信号的质量较好，该窄波束能满足该终端设备的通信需求，则基站使用该窄波束与终端设备进行下行业务的通信，不再尝试其它的窄波束；若该窄波束的RSRP小于目标RSRP，说明该终端设备通过该窄波束接收基站的下行信号的质量较差，该窄波束不能满足该终端设备的通信需求，则基站继续尝试使用另一个更窄的波束向终端设备发送下行信号，终端设备继续向基站上报该更窄波束的RSRP，直到基站确定终端设备上报的某个窄波束的RSRP能达到目标RSRP，即基站使用RSRP满足目标RSRP对应的窄波束与终端设备进行下行业务的通信。
例如，基站先使用窄波束0向终端设备发送下行信号，终端设备基于该窄波束0接收的下行信号测量得到该窄波束0的下行RSRP，并上报给基站。若基站确定终端设备上报的该窄波束0的下行RSRP不小于目标RSRP，则基站确定将使用该窄波束0与终端设备进行下行业务通信；若基站确定终端设备上报的该窄波束0的下行RSRP小于目标RSRP，基站尝试使用窄波束1(窄波束1的覆盖角度小于窄波束0的覆盖角度，窄波束1的覆盖距离大于窄波束0的覆盖距离)向终端设备发送下行信号，终端设备向基站上报该窄波束1的下行RSRP，若基站确定终端设备上报的该窄波束1的下行RSRP不小于目标RSRP，则基站确定将使用该窄波束1与终端设备进行下行业务通信，不再尝试其它的窄波束；若基站确定终端设备上报的该窄波束1的下行RSRP小于目标RSRP，基站继续尝试使用窄波束2(窄波束2的覆盖角度小于窄波束1的覆盖角度，窄波束2的覆盖距离大于窄波束1的覆盖距离)向终端设备发送下行信号，终端设备再次向基站上报该窄波束2的下行RSRP。直到基站根据终端设备上报的某个窄波束的下行RSRP达到目标RSRP，比如窄波束3，基站将使用窄波束3与终端设备进行下行业务通信。
执行方式二：基站可以同时通过至少一个窄波束向终端设备发送下行信号，相应的，终端设备通过该至少一个窄波束接收来自基站的下行信号，然后终端设备基于每个窄波束所接收的下行信号，测量得到每个窄波束的RSRP(相当于上述本申请中的信号接收质量)；进一步的，终端设备将测量得到的该至少一个窄波束的RSRP均上报给基站。
例如，终端设备通过窄波束0、窄波束1、窄波束2、窄波束3分别接收来自基站的下行信号，并基于窄波束0所接收的下行信号测量得到RSRP0，基于窄波束1所接收的下行信号测量得到RSRP1，基于窄波束2所接收的下行信号测量得到RSRP2，基于窄波束3所接收的下行信号测量得到RSRP3；然后，终端设备向基站发送(即上报)窄波束0的RSRP0、窄波束1的RSRP1、窄波束2的RSRP2、窄波束3的RSRP3。
上述各窄波束的RSRP可以作为反馈信息由终端设备直接上报给基站，或者上述各窄波束的RSRP携带在单独的反馈信息中由终端设备上报给基站，或者上述各窄波的RSRP均携带在同一个反馈信息中由终端设备上报给基站，本申请对此不做限定。
方法2：
方法2为基站根据终端设备上报的至少一个窄波束的下行接收情况，确定与终端设备进行下行通信使用的窄波束。基于该方法2，又可以包括但不限于以下两种执行方式：
执行方式一：基站可以先使用一个窄波束向终端设备发送下行信号，由终端设备确定通过该窄波束是否正确(或成功)地接收到来自基站的下行信号，并向基站上报反馈信息，以告知给基站(即终端设备的接收情况)。
基站根据该反馈信息，确定终端设备通过该窄波束是否可以成功(或正确)地接收到来自基站的下行信号；若可以，则基站将使用该窄波束与终端设备进行下行业务的通信，不再尝试其它的窄波束；若不可以，则基站继续尝试使用另一个更窄的波束向终端设备发送下行信号，终端设备继续向基站反馈接收情况，直到基站确定终端设备使用某个窄波束能成功接收到来自网络设备的下行信号，基站将该窄波束与终端设备进行下行业务的通信。
例如，基站先使用窄波束0向终端设备发送下行信号，终端设备确定通过该窄波束0是否能成功(或正确)地接收来自基站的下行信号，并向基站反馈该窄波束0的接收情况。基站根据终端设备上报的该窄波束0的接收情况，确定终端设备使用窄波束0能成功(或正确)地接收到基站的下行信号时，则不再尝试其它的窄波束，若基站确定终端设备使用窄波束0不能成功(或正确)地接收到基站的下行信号时，基站尝试使用窄波束1向终端设发送下行信号，终端设备向基站反馈该窄波束1的接收情况。直到基站根据终端设备上报的某个窄波束的接收情况，比如窄波束3的接收情况，确定终端设备通过该窄波束3能正确接收到来自基站的下行信号，则基站确定将使用该窄波束3与终端设备进行下行业务通信。
执行方式二：基站可以同时通过至少一个窄波束向终端设备发送下行信号，相应的，终端设备通过该至少一个窄波束接收来自基站的下行信号，终端设备向基站上报该至少一个窄波束的反馈信息，每个窄波束的反馈信息用于指示终端设备是否成功(或正确)地接收来自基站的下行信号。
例如，终端设备通过窄波束0、窄波束1、窄波束2、窄波束3分别接收来自基站的下行信号，终端设备确定通过各窄波是否成功(或正确)地接收到基站的下行信号，并向基站上报各窄波的反馈信息，每个反馈信息用于指示终端设备是否成功(或正确)地接收到基站的下行信号。
上述终端设备通过各窄波是否成功(或正确)地接收到基站的下行信号可以使用单独的指示信息进行指示，指示信息可以直接作为反馈信息，或者指示信息携带在反馈信息中。因此，各窄波对应的指示信息可以单独的由终端设备上报给基站，或者各窄波对应的指示信息可以携带在单独的反馈信息中由终端设备上报给基站，又或者各窄波对应的指示信息携带在同一反馈信息中由终端设备上报给基站，本申请对此不做具体限定。
需要注意的是，基站可以通过但不限于上述两种执行方式；由于上述执行方式一所产生的开销相对较小，因而本申请实施例中可以优先选择执行方式一(即遍历尝试的方式)。
S408：基站根据终端设备上报的反馈信息，确定与终端设备进行通信使用的窄波束。
当基于上述步骤S407中方法1对应的反馈方式，基站根据终端设备上报的各窄波束的RSRP，确定使用RSRP值最大的窄波束与终端设备进行通信。
例如，基站确定窄波束3的RSRP3最大，则基站确定使用窄波束3与终端设备进行下行通信。
当基于上述步骤S407中方法2对应的反馈方式，基站根据终端设备上报的各窄波束的反馈信息(或指示信息)，确定指示终端设备成功(或正确)地接收到基站的下行信号对应的窄波束，并用于与终端设备进行通信。
例如，基站确定窄波束3的反馈信息(指示信息)指示终端设备成功(正确地)接收到来自基站的下行信号，则基站确定使用窄波束3与终端设备进行下行通信。
需要注意的是，上述具体实施例一所示的步骤以一个基站和一个终端设备为例进行介绍，然而，在实际中，一个基站可能会与多个终端设备进行通信，因此，基站针对每个终端设备均可以参考上述具体实施例一中的步骤来确定通信所使用的下行波束，此处不再具体赘述。
通过该具体实施例一，基站可以终端设备反馈的下行参考信号的测量结果，确定终端设备的位置，针对近点位置的终端设备，基站可以采用宽波束与终端设备进行通信，从而增加了波束覆盖范围，可以为更多终端设备提供服务，节省了资源开销。针对远点位置的终端设备，基站可以在原宽波束范围内进行下行遍历试探窄波束，以选择到覆盖更好的窄波束与终端设备进行通信，既保证了有效的通信，同时也考虑到波束的覆盖范围，以为更多终端设备提供服务，节省了资源开销。因此，通过该方式可以同时兼顾宽窄波束的优点，为终端设备确定合适的服务波束，既保证了基站与终端设备通信的有效性，同时也节省了资源开销。
此外，针对上下行互易性较好的场景，基站通过上述具体实施例一所确定的下行波束，既可以用于与终端设备进行下行业务的通信，也可以复用作为上行波束，以用于与终端设备进行上行业务的通信，基站无需再通过下述具体实施例二为终端设备确定合适的上行波束。
针对上下行互易性较差的场景，基站可以通过下述具体实施例二来确定上行波束，以用于终端设备进行上行业务的通信。
具体实施例二
在该具体实施二中，针对上下行互易性较差的场景，网络设备如何确定合适的上行波束，以与终端设备进行上行通信。该网络设备以基站为例，如图5所示，该具体实施例二的流程如下：
S501：基站使用宽波束接收来自终端设备的上行信号。
在该步骤S501中，基站使用一个或多个宽波束(也可以称为基线波束)接收来自终端设备的上行信号。
示例性地，该上行信号可以为上行通信信号，也可以为上行参考信号，例如SRS、CSI-RS。
例如，基站分别使用宽波束0、宽波束1、宽波束2接收来自终端设备的上行信号。
S502：基站基于宽波束所接收的上行信号，测量得到宽波束的RSRP。
例如，基站基于宽波束0所接收的上行信号测量得到宽波束0的上行RSRP；基站基于宽波束1所 接收的上行信号，测量得到宽波束1的上行RSRP；基站基于宽波束2所接收的上行信号测量得到宽波束2的上行RSRP。
S503：基站根据最优宽波束的RSRP，确定终端设备的位置。
在该步骤S503中，若基站确定最优宽波束的上行RSRP大于或等于预设的上行RSRP阈值时，则基站确定该终端设备处于近点位置(中近点)；若基站确定最优宽波束的上行RSRP小于预设的上行RSRP阈值时，则基站确定该终端设备处于远点位置(远点)。
例如，若基站确定宽波束1的上行RSRP的值均大于宽波束0的上行RSRP值和宽波束2的上行RSRP值，基站将宽波束1视为最优宽波束。若基站确定宽波束1的上行RSRP值大于或等于预设的上行RSRP阈值，则基站确定该终端设备处于近点位置；若基站确定宽波束1的上行RSRP值小于预设的上行RSRP阈值，则基站确定该终端设备处于远点位置。
S504：基站根据终端设备的位置，确定与该终端设备进行通信的波束。
在执行该步骤S504时，可能包括以下两种情况：
情况1：若通过上述步骤S503，基站确定终端设备处于近点位置时，则在该步骤S504中基站继续使用上述最优宽波束与该终端设备进行上行通信(或传输)，不再执行下述步骤S505-S506。
情况2：若通过上述步骤S503，基站确定终端设备处于远点位置时，说明上述最优宽波束的覆盖不足，会导致终端设备的上行业务较差，因此，基站继续通过下述步骤S505-S506确定合适的波束，与终端设备进行上行业务通信。
S505：基站在最优宽波束的覆盖范围内，使用至少一个窄波束接收来自终端设备的上行信号。
相应的，终端设备在上述步骤S503中所确定的最优宽波束的覆盖范围内，分别通过该至少一个窄波束向基站发送上行信号。
该步骤S505中的上行信号也可以通信信号，也可以为上行参考信号，本申请实施例对此不做限定。例如，该上行信号为SRS或CSI-RS。
在上述步骤S503中，若基站确定终端设备处于远点位置，则基站在最优上行RSRP对应的宽波束的覆盖范围内，上行遍历尝试更窄的波束接收来自终端设备的上行信号。
例如，基站在最优宽波束1的覆盖范围(或角度)内，分别尝试使用窄波束0、窄波束1、窄波束2、窄波束3分别接收来自终端设备的上行信号。这些窄波束的覆盖角度和覆盖距离(长度)均不同，窄波束0的覆盖角度>(大于)窄波束1的覆盖角度>(大于)窄波束2的覆盖角度>(大于)窄波束3的覆盖角度。
S506：基站基于通过该至少一个窄波束所接收的上行信号，确定与终端设备进行上行通信使用的窄波束。
在执行该步骤S506时，可以通过但不限于以下两种方式确定：
方法1：
方法1为基站可以根据至少一个窄波束的上行RSRP，确定与终端设备进行上行通信使用的窄波束。基于该方法1，又可以包括但不限于以下两种执行方式：
执行方式一：基站先采用一个窄波束接收来自终端设备的上行信号，并测量得到该窄波束对应的上行RSRP。若该窄波束的上行RSRP满足目标上行RSRP，则基站确定使用该窄波束与终端设备进行上行业务通信，不再尝试其它的窄波束；若该窄波束的上行RSRP不满足目标上行RSRP，则基站尝试使用另一个更窄的波束接收来自终端设备的上行信号，并测量得到该更窄波束的上行RSRP，若满足目标上行RSRP，则基站使用该更窄波束与终端设备进行上行业务通信，若不满足目标上行RSRP，则基站按照前述的方式，继续尝试其它的更窄波束，直到某个窄波束的上行RSRP满足目标上行RSRP，基站将使用RSRP满足目标上行RSRP对应的窄波束与终端设备进行上行业务通信。(对应于上述具体实施一中的执行方式二)。
例如，基站先使用窄波束0接收来自终端设备上行信号，测量得到该窄波束0的上行RSRP，若满足目标上行RSRP，则基站确定使用该窄波束0与终端设备进行上行业务通信，若不满足目标上行RSRP，基站尝试使用窄波束1(窄波束1的覆盖角度小于窄波束0的覆盖角度，窄波束1的覆盖距离大于窄波束0的覆盖距离)接收来自终端设备的上行信号，并测得该窄波束1的上行RSRP，若满足目标上行RSRP，则基站确定使用该窄波束1与终端设备进行上行业务通信，若不满足目标上行RSRP，则基站根据前述方式，继续尝试使用窄波束2(窄波束2的覆盖角度小于窄波束1的覆盖角度，窄波束2的覆盖距离大于窄波 束1的覆盖距离)接收来自终端设备的上行信号并测得该窄波束2的上行RSRP，直到测得某个窄波束的上行RSRP满足目标上行RSRP，则基站将使用RSRP满足目标上行RSRP对应的窄波束与终端设备进行上行业务通信。
执行方式二：基站可以同时通过至少一个窄波束接收来自终端设备的上行信号，然后基站基于每个窄波束所接收的上行信号，测量得到每个窄波束的上行RSRP(相当于上述本申请中的信号接收质量)，基站从该至少一个窄波束的上行RSRP中确定最大的RSRP；基站将使用上行RSRP最大的窄波束，与终端设备进行上行业务通信。
例如，基站使用窄波束0、窄波束1、窄波束2、窄波束3分别接收来自终端设备的上行信号，并基于窄波束0所接收的上行信号测量得到上行RSRP0，基于窄波束1所接收的上行信号测量得到上行RSRP1，基于窄波束2所接收的上行信号测量得到上行RSRP2，基于窄波束3所接收的上行信号测量得到上行RSRP3；若基站确定窄波束3的上行RSRP3最大，则基站使用窄波束3与终端设备进行上行业务通信。
方法2：
方法2为基站根据至少一个窄波束的上行接收情况，确定与终端设备进行上行通信使用的窄波束。基于该方法2，又可以包括但不限于以下两种执行方式：
执行方式一：基站先使用一个窄波束接收来自终端设备的上行信号，若基站能成功(或正确)地接收到来自终端设备的上行信号，则基站确定将使用该窄波束与终端设备进行上行业务通信，不再尝试其它的窄波束；若基站不能成功(或正确)地接收到来自终端设备的上行信号，则基站尝试使用另一个更窄的波束接收来自终端设备的上行信号，若基站能成功(或正确)地接收到来自终端设备的上行信号，则基站将使用该更窄的波束与终端设备进行上行业务通信，若不能成功(或正确)地接收到来自终端设备的上行信号，则基站根据前述方式继续尝试使用其它更窄的波束接收来自终端设备的上行信号。直至基站使用某个窄波束能成功(或正确)地接收到来自终端设备的上行信号，基站将使用该能使基站成功(或正确)地接收到来自终端设备的上行信号的窄波束，与终端设备进行上行业务通信。
例如，基站先使用窄波束0接收来自终端设备上行信号，若基站能使用窄波束0成功(或正确)地接收到来自终端设备的上行信号，则基站确定将使用该窄波束0与终端设备进行上行业务通信，则不再尝试其它的窄波束；若基站能使用窄波束0不能成功(或正确)地接收到来自终端设备的上行信号，基站尝试使用窄波束1(窄波束1的覆盖角度小于窄波束0的覆盖角度，窄波束1的覆盖距离大于窄波束0的覆盖距离)接收来自终端设备的上行信号，若基站能使用窄波束1成功(或正确)地接收到来自终端设备的上行信号，则基站确定将使用该窄波束1与终端设备进行上行业务通信；若基站能使用窄波束1不能成功(或正确)地接收到来自终端设备的上行信号，则基站根据前述的方式继续尝试使用窄波束2(窄波束2的覆盖角度小于窄波束1的覆盖角度，窄波束2的覆盖距离大于窄波束1的覆盖距离)能否正确接收到来自终端设备的上行信号。直到基站可以使用其中某个窄波束能成功(或正确)地接收到来自网络设备的上行信号，则基站将使用该窄波束与终端设备进行上行业务通信。
执行方式二：基站可以同时使用至少一个窄波束接收来自终端设备的上行信号，基站确定通过其中某个窄波束能够成功(或正确)地接收到来自终端设备的上行信号，基站将使用该窄波束与终端设备进行上行业务通信。
例如，基站使用窄波束0、窄波束1、窄波束2、窄波束3分别接收来自终端设备的上行信号，基站通过窄波束0、1、2均不能成功(或正确)地接收到来自终端设备的上行信号，基站通过窄波束3能成功(或正确)地接收到来自终端设备的上行信号，那么基站确定将使用窄波束3与终端设备进行上行业务通信。
需要注意的是，基站可以通过但不限于上述两种执行方式；由于上述执行方式一所产生的开销相对较小，因而本申请实施例中可以优先选择执行方式一(即遍历尝试的方式)。
另外，上述具体实施例二所示的步骤以一个基站和一个终端设备为例进行介绍，然而，在实际中，一个基站可能会与多个终端设备进行通信，因此，基站针对每个终端设备均可以参考上述具体实施例二中的步骤来确定通信所使用的上行波束，此处不再具体赘述。
通过该具体实施例二，基站使用宽波束接收来自终端设备的上行信号，并得到该宽波束的测量结果或接收情况；然后，基站根据该宽波束的测量结果或接收情况，确定终端设备的位置，针对近点位置的终端设备，基站可以继续采用宽波束与终端设备进行通信，从而增加了波束覆盖范围，可以为更多终端设备提供服务，节省了资源开销。针对远点位置的终端设备，基站可以在原宽波束范围内进行上行遍历试探窄波束，以选择到覆盖更好的窄波束与终端设备进行通信，既保证了有效的通信，同时也考虑到波 束的覆盖范围，以为更多终端设备提供服务，节省了资源开销。因此，通过该方式可以同时兼顾宽窄波束的优点，为终端设备确定合适的服务波束，既保证了基站与终端设备通信的有效性，同时也节省了资源开销。
此外，针对上下行互易性较好的场景，基站通过上述具体实施例二所确定的上行波束，既可以用于与终端设备进行上行业务的通信，也可以复用作为下行波束，以用于与终端设备进行下行业务的通信，基站无需再通过上述具体实施例一为终端设备确定合适的下行波束。
针对上下行互易性较差的场景，基站可以通过上述具体实施例一来确定下行波束，以用于终端设备进行下行业务的通信。
