作为示例而非限定，在本申请实施例中，可穿戴设备也可以称为穿戴式智能设备，是应用穿戴式技术对日常穿戴进行智能化设计、开发出可以穿戴的设备的总称，如眼镜、手套、手表、服饰及鞋等。可穿戴设备即直接穿在身上，或是整合到用户的衣服或配件的一种便携式设备。可穿戴设备不仅仅是一种硬件设备，更是通过软件支持以及数据交互、云端交互来实现强大的功能。广义穿戴式智能设备包括功能全、尺寸大、可不依赖智能手机实现完整或者部分的功能，例如：智能手表或智能眼镜等，以及只专注于某一类应用功能，需要和其它设备如智能手机配合使用，如各类进行体征监测的智能手环、智能首饰等。
此外，在本申请实施例中，终端设备还可以是IoT***中的终端设备，IoT是未来信息技术发展的重要组成部分，其主要技术特点是将物品通过通信技术与网络连接，从而实现人机互连，物物互连的智能化网络。在本申请实施例中，IOT技术可以通过例如窄带(narrow band，NB)技术，做到海量连接，深度覆盖，终端省电。
此外，在本申请实施例中，终端设备还可以包括智能打印机、火车探测器、加油站等传感器，主要功能包括收集数据(部分终端设备)、接收网络设备的控制信息与下行数据， 并发送电磁波，向网络设备传输上行数据。
本申请实施例中的网络设备可以是用于与终端设备通信的任意一种具有无线收发功能的通信设备。该设备包括但不限于：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(home evolved NodeB，HeNB，或home Node B，HNB)、基带单元(baseBand unit，BBU)，无线保真(wireless fidelity，WIFI)***中的接入点(access point，AP)、无线中继节点、无线回传节点、传输点(transmission point，TP)或者发送接收点(transmission and reception point，TRP)等，还可以为5G***，如，NR***中的gNB，或，传输点(TRP或TP)，5G***中的基站的一个或一组(包括多个天线面板)天线面板，或者，还可以为构成gNB或传输点的网络节点，如基带单元(BBU)，或，分布式单元(distributed unit，DU)等。本申请实施例中的网络设备也可以称为接入网设备。
在一些部署中，本申请实施例中的网络设备可以是指集中单元(central unit，CU)或者分布式单元(distributed unit，DU)或者，网络设备包括CU和DU。gNB还可以包括有源天线单元(active antenna unit，AAU)。CU实现gNB的部分功能，DU实现gNB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划分为接入网(radio access network，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。
进一步地，CU还可以划分为控制面的中央单元(CU-CP)和用户面的中央单元(CU-UP)。其中，CU-CP和CU-UP也可以部署在不同的物理设备上，CU-CP负责控制面功能，主要包含RRC层和PDCP-C层。PDCP-C层主要负责控制面数据的加解密，完整性保护，数据传输等。CU-UP负责用户面功能，主要包含SDAP层和PDCP-U层。其中SDAP层主要负责将核心网的数据进行处理并将流(flow)映射到承载。PDCP-U层主要负责数据面的加解密，完整性保护，头压缩，序列号维护，数据传输等至少一种功能。具体地，CU-CP和CU-UP通过通信接口(例如，E1接口)连接。CU-CP代表网络设备通过通信接口(例如，Ng接口)和核心网设备连接，通过通信接口(例如，F1-C(控制面)接口)和DU连接。CU-UP通过通信接口(例如，F1-U(用户面)接口)和DU连接。
还有一种可能的实现，PDCP-C层也包含在CU-UP中。
可以理解的是，以上关于CU和DU，以及CU-CP和CU-UP的协议层划分仅为示例，也可能有其他的划分方式，本申请实施例对此不做限定。
本申请实施例所提及的网络设备可以为包括CU、或DU、或包括CU和DU的设备、 或者控制面CU节点(CU-CP节点)和用户面CU节点(CU-UP节点)以及DU节点的设备。
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、气球和卫星上。本申请实施例中对网络设备和终端设备所处的场景不做限定。
在本申请实施例中，终端设备或网络设备包括硬件层、运行在硬件层之上的操作***层，以及运行在操作***层上的应用层。该硬件层包括中央处理器(central processing unit，CPU)、内存管理单元(memory management unit，MMU)和内存(也称为主存)等硬件。该操作***可以是任意一种或多种通过进程(process)实现业务处理的计算机操作***，例如，Linux操作***、Unix操作***、Android操作***、iOS操作***或windows操作***等。该应用层包含浏览器、通讯录、文字处理软件、即时通信软件等应用。
图1为本申请实施例可以应用的无线通信***100的示意性架构图。如图1所示，无线通信***100中可以包括一个或多个网络设备110，一个或多个终端设备120，以及核心网130。
网络设备110可以用于与一个或多个终端设备120进行通信，也可以用于与一个或多个具有部分终端设备功能的基站进行通信。可选地，网络设备110可用于在网络设备控制器(图1中未示出)的控制下，通过一个或多个天线与终端设备120通信。其中，该网络设备控制器可以是核心网130的一部分，也可以集成到网络设备110中。可选的，网络设备110向核心网130传输控制信息或者用户数据。进一步的，网络设备110之间也可以直接或间接地通信。
本申请实施例中，网络设备之间可以交互SSB的相关信息和CSI-RS的相关信息，例如第一网络设备和第二网络设备之间可以交互SSB的相关信息和CSI-RS的相关信息。第一网络设备和第二网络设备之间的交互可以包括第一网络设备向第二网络设备发送SSB的相关信息和CSI-RS的相关信息，也可以包括第二网络设备向第一网络设备发送SSB的相关信息和CSI-RS的相关信息。例如，当两个网络设备是基站或者CU时，该两个网络设备可以通过X2或者Xn接***互SSB的相关信息和CSI-RS的相关信息；当第一网络设备是DU，第二网络设备是CU时，或者，第一网络设备是CU，第二网络设备是DU时，两个网络设备通过F1接***互SSB的相关信息和CSI-RS的相关信息。
需要说明的是，SSB和CSI-RS通过一个或者多个波束发送。波束可以理解为空间资源，可以指具有能量传输指向性的发送或接收预编码向量。并且，该发送或接收预编码向量能够通过索引信息进行标识，所述索引信息可以对应配置终端的资源标识(identity，ID)，比如，所述索引信息可以对应配置的CSI-RS的标识或者资源；也可以是对应配置的SSB的标识或者资源；也可以是对应配置的上行探测参考信号(Sounding Reference Signal，SRS)的标识或者资源。可选地，所述索引信息也可以是通过波束承载的信号或信道显示或隐式承载的索引信息。所述能量传输指向性可以指通过该预编码向量对所需发送的信号进行预编码处理，经过该预编码处理的信号具有一定的空间指向性，接收经过该预编码向量进行预编码处理后的信号具有较好的接收功率，如满足接收解调信噪比等；所述能量传输指向性也可以指通过该预编码向量接收来自不同空间位置发送的相同信号具有不同的接收功率。
可选地，同一通信装置(比如终端设备或网络设备)可以有不同的预编码向量，不同的设备也可以有不同的预编码向量，即对应不同的波束。针对通信装置的配置或者能力，一个通信装置在同一时刻可以使用多个不同的预编码向量中的一个或者多个，即同时可以形成一个波束或者多个波束。
上述SSB的相关信息可以包括但不限于以下至少一种：SSB的频点信息(例如carrierFreq)、SSB子载波间隔(ssbSubcarrierSpacing)、SSB测量定时配置(例如ssb-MeasurementTimingConfiguration)、SSB对应的物理小区标识(physical cell ID，PCI)。SSB的相关信息也可以称为SSB的配置信息或者SSB资源信息，或者也可以称为SSB对应的配置信息等，本申请实施例对此不做限定。
上述CSI-RS的相关信息可以包括但不限于以下至少一种：CSI-RS的索引、CSI-RS的子载波间隔、CSI-RS的周期(periodicity)和偏置(offset)，CSI-RS所占用的频域位置，CSI-RS序列的加扰序列。CSI-RS的相关信息也可以称为CSI-RS的配置信息或者CSI-RS资源信息，或者也可以称为CSI-RS对应的配置信息，本申请实施例对此不做限定。其中，上述偏置和周期可以用来确定CSI-RS的部分时域信息，例如可以用于确定CSI-RS在时域上是从哪个子帧开始。
本申请的发明人发现，由于CSI-RS本身不具备同步功能，如果把上述的CSI-RS的相关信息在网络设备间交互，会存在作为接收方的网络设备在接收到CSI-RS后不知道该CSI-RS的准确时域位置。因此，本申请实施例的一些可能实现方式中，上述CSI-RS的相关信息中还可以包括用于确定CSI-RS的定时信息的信息。可以理解的，本申请实施例的又一些实现方式中，也可以不用在网络设备之间交互用于确定CSI-RS的定时信息的信息，例如通过协议约定或者预先配置或者其他方式实现CSI-RS的定时信息的确定。下文中的实施例结合附图分别描述不同的实现方式。
如图2所示，本申请一实施例提供了一种通信方法，可以包括：
S201，第一网络设备在至少一个同步信号块中确定参考同步信号块SSB。
本实施例中，可以通过协议约定或者预先配置第X个SSB(即至少一个同步信号块中固定序号对应的同步信号块)作为参考SSB，那么第一网络设备将第X个SSB作为参考SSB。例如，假设第一网络设备将要向或者已经向第二网络设备发送分别对应频点1、频点2和频点3的SSB的配置信息，且X为1，那么第一网络设备确定第1个SSB(即频点1对应的同步信号块)为参考SSB。可以理解的是，X也可以为其他数值，本申请实施例对此不做限定。
或者也可以通过协议约定或者预先配置确定固定频点对应的SSB为参考SSB，那么第一网络设备将该固定频点对应的SSB为参考SSB。例如，假设第一网络设备将要向或者已经向第二网络设备发送分别对应频点1、频点2和频点3的SSB的配置信息，协议约定或者预先配置的固定频点为频点2，那么第一网络设备确定将频点2对应的SSB为参考SSB。
其中，一种可能的预先配置的实现方式可能是：核心网设备将参考同步信号块的信息发送给第一网络设备和第二网络设备。
S202，该第一网络设备向第二网络设备发送至少一个SSB对应的配置信息。
相应的，该第二网络设备会接收到第一网络设备发送的该至少一个SSB对应的配置 信息，从而可以进行相应的处理，例如给第二网络设备下的终端设备进行相关的配置，本申请实施例对于第二网络设备对接收到的至少一个SSB对应的配置信息的后续处理不做限定。
如前所述，SSB对应的配置信息也可以称为SSB的配置信息或者SSB的相关信息等，关于SSB对应的配置信息的内容此处不再赘述。可以理解的是，上述至少一个SSB与至少一个频点分别对应，该至少一个频点可以包括第一网络设备所管理的小区对应的频点和该第一网络设备所管理的小区的邻区(该邻区可以是其他网络设备所管理的小区)对应的频点中的至少一个频点。
其中，该至少一个SSB对应的配置信息可以通过网络设备间的交互信息传输，该交互信息例如可以是测量定时配置(MeasurementTimingConfiguration)信息。该MeasurementTimingConfiguration信息例如可以包括如下信元结构：
Figure PCTCN2019113498-appb-000001
其中，MeasTimingList(测量定时列表)中包括了至少一个SSB对应的配置信息。
可以理解的是，以上信元结构仅为举例，本申请实施例对发送该至少一个SSB对应的配置信息的信元结构和消息载体等不做限定。并且，上述信元结构是以示意为目的，本申请实施例该信元结构中各个信息名称不一一介绍。
此外，本申请实施例对S201和S202的执行顺序不做限定，也就是说，S202可以在S201之前或者之后执行，或者S201和S202也可以同时执行。
S203，该第一网络设备向该第二网络设备发送至少一个CSI-RS对应的配置信息。
此处，CSI-RS为第一参考信号的一种举例，可以理解的是，第一参考信号也可以是其他参考信号，本申请实施例对此不做限定。此外，本申请实施例也不限制于为参考信号，也可以是其他信号，只要存在与本申请实施例中CSI-RS类似问题的信号都可以适用。
第二网络设备会接收到第一网络设备发送的该至少一个CSI-RS对应的配置信息，从而可以进行相应的处理，例如给第二网络设备下的终端设备进行相关的配置，本申请实施例对于第二网络设备对接收到的至少一个CSI-RS对应的配置信息的后续处理不做限定。
如前所述，CSI-RS对应的配置信息也可以称为CSI-RS的配置信息或者CSI-RS的相关信息等，关于CSI-RS对应的配置信息的内容此处不再赘述。该至少一个CSI-RS对应的配置信息可以包括该第一网络设备所管理的小区所对应的CSI-RS配置信息和该第一网络设备所管理的小区的邻区所发送的CSI-RS的配置信息中的至少一个CSI-RS配置信息。
其中，该至少一个CSI-RS对应的配置信息也可以通过网络设备间的交互信息传输，例如可以通过与发送至少一个SSB对应的配置信息相同或者不同的消息发送至少一个CSI-RS对应的配置信息。
当该至少一个CSI-RS对应的配置信息通过与发送至少一个SSB对应的配置信息相同的消息发送时，一种可能的实现方式中，可以将该至少一个CSI-RS对应的配置信息也携带中MeasurementTimingConfiguration中。
其中，该至少一个CSI-RS的配置信息是根据参考SSB的定时信息确定的，例如CSI-RS的配置信息中的偏置可以基于参考SSB的定时确定。
需要说明的是，基于参考SSB的定时，可以理解为，基于参考SSB对应的小区的定时。
相应的，该至少一个CSI-RS的配置信息是根据参考SSB的定时信息确定的也可以说是基于参考SSB对应的小区的定时信息确定该至少一个CSI-RS的配置信息。比如，根据参考SSB的频点以及小区标识信息确定出参考小区，以该参考小区的定时信息(例如可以包括帧号，子帧号等)作为参考来确定CSI-RS的时域位置(例如前面所提到的偏置)。前述小区标识信息可以包括物理小区标识(physical cell id，PCI)和/或小区全球标识(cell global id，CGI)，该小区标识信息可以是直接与CSI-RS配置信息携带在相同的消息里，例如带在Container(容器)里通过X2/Xn/F1接***互，或者该小区标识信息可以带在X2/Xn/F1接口携带CSI-RS配置的Container的消息里(即，带在Container外面而不是Container里面)。作为一个示例，该CSI-RS配置信息中的periodicity和offset确定了该CSI-RS配置信息会在第M帧的第N子帧出现，那么当该CSI-RS配置信息以第一小区(参考SSB对应的小区)作为参考小区时，第M帧的第N子帧指的是第一小区的第M帧的第N子帧。
本申请实施例中，对S202和S203的执行顺序也不做限定，也就是说S202和S203可以同时执行，或者S202在S203之前或者之后执行。
S204，该第二网络设备根据参考SSB的定时信息确定该至少一个CSI-RS的定时信息。
其中，SSB的定时信息指的是SSB对应的小区的定时信息，该定时信息例如可以包括但不限于以下至少一种：帧号，子帧号，帧边界信息。
根据协议的约定或者预先配置，该第二网络设备获知根据第X个SSB或者固定频点对应的SSB作为参考SSB，从而确定根据该参考SSB的定时信息确定该至少一个CSI-RS的定时信息。
在第二网络设备确定根据该参考SSB的定时信息确定该至少一个CSI-RS的定时信息后，可以进行后续的处理，例如，配置第二网络设备所服务的终端设备进行相应的CSI-RS 测量。
需要说明的是，根据参考SSB的定时信息确定CSI-RS的定时信息也可以理解为，根据参考SSB所对应的小区的定时信息确定CSI-RS的定时信息。例如，参考信号CSI-RS的时域位置是参考所述小区的定时信息(包括帧号，子帧号等)来确定，或者说，根据参考信号CSI-RS的配置，可以确定参考信号CSI-RS出现在小区的哪些子帧。
本申请实施例中，通过协议约定或者预先配置固定频点对应的同步信号块或者该至少一个同步信号块中固定序号对应的同步信号块作为参考同步信号块，来作为确定至少一个CSI-RS的定时信息的依据，从而能够准确地获知CSI-RS的时域出现时间，提高通信效率，进一步的，可以使得第二网络设备能够准确有效地在空口配置用户设备进行CSI-RS测量，提高测量准确性，作为终端设备移动性(包括小区重选，切换，等)的基础。
本申请又一实施例提供了一种通信方法，与图2所示的通信方法所不同的是，该通信方法中，参考同步信号块可以不是预先约定或者配置的，而是第二网络设备可以通过第一网络设备的指示来确定参考同步信号块，如图3所示，该通信方法可以包括：
S301，第一网络设备在至少一个同步信号块中确定参考同步信号块SSB。
其中，第一网络设备可以根据一定的规则或者需求或者随机在该至少一个同步信号块中确定参考SSB。一种可能的方式可以为：第一网络设备可以选择CD-SSB作为参考SSB。其中，CD-SSB指的是关联到剩余最小***信息(remaining minimum system information，RMSI)的SSB。CD-SSB也可以理解为关联到SIB1的SSB。CD-SSB可以用于驻留，或者用于终端设备的主小区配置。
S302，该第一网络设备向第二网络设备发送至少一个SSB对应的配置信息。
其中，S302的具体描述可以参考S202处相关描述，此处不再赘述。
S303，该第一网络设备向该第二网络设备发送至少一个CSI-RS对应的配置信息。
其中，S303的具体描述可以参考S203处相关描述，此处不再赘述。
S304，该第一网络设备向第二网络设备发送第一指示信息，其中，该第一指示信息用于第二网络设备确定参考SSB。
相应的，该第二网络设备在接收到该第一指示信息后，可以确定出参考SSB。
其中，该第一指示信息可以指示参考SSB对应的频点信息或者指示该参考SSB对应的标识(也可以叫做序号)。
一种可能的实现方式中，该第一指示信息指示参考SSB对应的频点信息可以是该第一指示信息携带参考SSB对应的频点信息，例如，上述至少一个SSB对应的频点分别是频点1，频点2和频点3，该第一指示信息可以携带频点2的信息，那么第二网络设备可以获知参考SSB是频点2对应的SSB。
又一种可能的方式中，该第一指示信息指示参考SSB对应的频点信息可以是每个SSB的配置信息中对应携带用于指示该SSB是否可以作为参考SSB。也就是说每个频点级的SSB的配置信息进行指示该SSB是否可以作为参考SSB。例如，假设有频点1对应的SSB的配置信息，频点2对应的SSB的配置信息，以及频点3对应的SSB的配置信息，那么在频点1对应的SSB的配置信息中可以指示该SSB可以作为参考SSB，其他两个频点对应的SSB的配置信息中指示该SSB不作为参考SSB，那么第二网络设备可以获知频点1对应的SSB为参考SSB。对于如何实现指示某个SSB是否作为参考SSB，本申请实施例 不做限定，例如通过至少一个比特的信息或者字段来实现，当该字段为“1”或者“TRUE”时表示作为参考SSB，当该字段为“0”或者“FALSE”时表示不作为参考SSB。或者，也可以是只在参考SSB的配置信息中有相应的指示信息，不作为参考SSB的SSB的配置信息中不携带相关指示时，默认表示不作为参考SSB，或者也可以是不作为参考SSB的SSB的配置信息中携带相关指示，而参考SSB的配置信息中不携带相关指示。
一种可能的实现方式中，上述参考SSB对应的标识可以是数字标识，表示上述至少一个SSB中第几个SSB作为参考SSB。该标识可以从0开始，即标识0对应的SSB为第1个SSB，以此类推，或者该标识也可以从1开始，即标识1对应的SSB为第1个SSB。以此类推。可以理解的是，该标识也可以从其他数值开始，只要能让第二网络设备知道是至少一个SSB中的第几个SSB作为参考SSB即可，本申请实施例对此不做限定。
需要说明的是，该第一指示信息可以和上述至少一个SSB对应的配置信息在相同或者不同的消息发送，或者该第一指示信息也可以和上述至少一个CSI-RS对应的配置信息在相同或者不同的消息中发送。此外，S304可以在S302或者S303之前或者之后或者同时执行，本申请实施例对此不做限定。
S305，该第二网络设备根据参考SSB的定时信息确定该至少一个CSI-RS的定时信息。
第二网络设备接收到第一指示信息后，确定要根据参考SSB的定时信息确定该至少一个CSI-RS的定时信息，那么第二网络设备可以根据第一指示信息的指示确定参考SSB，从而根据参考SSB的定时信息确定该至少一个CSI-RS的定时信息。
其中，S305的具体描述还可以进一步参考S204处相关描述，此处不再赘述。
本申请实施例中，通过第一指示信息指示参考SSB，从而可以使得第二网络设备获知确定CSI-RS的定时的参考SSB，从而能够准确地获知CSI-RS的时域出现时间，提高通信效率，进一步的，可以使得第二网络设备能够准确有效地在空口配置用户设备进行CSI-RS测量，提高测量准确性，作为终端设备移动性(包括小区重选，切换，等)的基础。
本申请再一实施例还提供了一种通信方法，与图3所示实施例通过第一指示信息指明参考SSB不同的是，本实施例中通过至少一个SSB的同步状态的指示来使得第二网络设备获知参考SSB，如图4所示，该方法可以包括：
S401，第一网络设备在至少一个同步信号块中确定参考同步信号块SSB。
第一网络设备可以根据在该至少一个SSB的同步状态在该至少一个SSB中确定参考SSB，其中，在该至少一个SSB中所有SSB均为同步的情况下，该第一网络设备可以将任意一个SSB确定为参考SSB。或者，在该至少一个SSB中并非所有SSB均为同步的情况下，该第一网络设备可以将该至少一个SSB中的固定频点对应的SSB或者所述参考同步信号块为所述至少一个SSB中固定序号对应的SSB。其中，并非所有SSB均为同步可以包括所有的SSB不同步，或者有一个或者多个SSB与其他SSB不同步。
其中，SSB同步，表示SSB对应的小区同步。例如可以理解为，SSB1和SSB2同步，表示SSB1对应的小区1和SSB2对应的小区2的***帧号(SFN)同步以及帧边界同步，这里SFN同步可以理解为SFN相同，帧边界同步可以理解为帧边界对齐。
S402，该第一网络设备向第二网络设备发送至少一个SSB对应的配置信息。
S403，该第一网络设备向该第二网络设备发送至少一个CSI-RS对应的配置信息。
其中，S402和S403可以分别参考S202和S203处的相关描述，此处不再赘述。
S404，该第一网络设备向该第二网络设备发送第二指示信息，其中，该第二指示信息用于第二网络设备确定参考SSB。
一些可能的实现方式中，该第二指示信息用于第二网络设备确定所述至少一个同步信号块中所有的同步信号块的同步状态。
对于如何实现指示同步状态，本申请实施例不做限定，例如可以通过至少一个比特的信息或者字段来实现，当该字段为“1”或者“TRUE”时表示至少一个SSB中所有的SSB同步，当该字段为“0”或者“FALSE”时表示至少一个SSB中并非所有的SSB均同步。或者，也可以是只在所有SSB同步时发送第二指示信息，当未发送第二指示信息时表示并非所有的SSB均同步。或者，也可以是在并非所有的SSB均同步时发送第二指示信息，而所有SSB同步时不发送第二指示信息。从而可以使得第二网络设备获知该至少一个SSB的同步状态，便于确定参考SSB。
需要说明的是，该第二指示信息可以和上述至少一个SSB对应的配置信息在相同或者不同的消息发送，或者该第一指示信息也可以和上述至少一个CSI-RS对应的配置信息在相同或者不同的消息中发送。此外，S404可以在S402或者S403之前或者之后或者同时执行，本申请实施例对此不做限定。
S405，该第二网络设备根据参考SSB的定时信息确定该至少一个CSI-RS的定时信息。
第二网络设备可以根据第二指示信息获知该至少一个SSB的同步状态，从而确定出参考SSB。例如，与第一网络设备类似的，第二网络设备在该至少一个SSB中所有SSB同步的情况下，可以将任意一个SSB确定为参考SSB。或者，在该至少一个SSB中并非所有SSB均为同步的情况下，该第二网络设备可以将该至少一个SSB中的固定频点对应的SSB或者所述参考同步信号块为所述至少一个SSB中固定序号对应的SSB。
其中，S405的具体描述还可以进一步参考S204处相关描述，此处不再赘述。
本申请实施例中，通过第二指示信息指示用于确定参考SSB的相关信息，可以使得第二网络设备可以获知确定CSI-RS的定时的参考SSB，从而能够准确地获知CSI-RS的时域出现时间，提高通信效率，进一步的，可以使得第二网络设备能够准确有效地在空口配置用户设备进行CSI-RS测量，提高测量准确性，作为终端设备移动性(包括小区重选，切换，等)的基础
此外，还有一种可能的实施例中，当第一网络设备向第二网络设备发送的至少一个SSB的配置信息中包括多个SSB频点时，可以默认该多个SSB是同步的，那么该可能的实施例流程与图4所示实施例类似，所不同的是，不需要确认SSB的同步状态，而是默认是同步的，那么也就不需要执行S404，第二网络设备可以将多个SSB中任意一个SSB作为参考SSB或者将某个固定频点对应的同步信号块或者固定序号对应的同步信号块确定为参考SSB该实施例中，通过协议规定当第一网络设备向第二网络设备发送的至少一个SSB的配置信息中包括多个SSB频点时，该多个SSB是同步的，确定CSI-RS的定时参考为任一SSB频点上的SSB，从而能够准确地获知CSI-RS的时域出现时间，提高通信效率，进一步的，可以使得第二网络设备能够准确有效地在空口配置用户设备进行CSI-RS测量，提高测量准确性，作为终端设备移动性(包括小区重选，切换，等)的基础
上述默认该多个SSB是同步的，也可以理解为协议规定当发送多个频点的SSB的配 置信息时，该多个SSB是要同步的。
可选的，在以上各个方法实施例的基础上，还可以包括：第一网络设备向第二网络设备发送SSB index(索引)信息，该SSB index信息可以指示CSI-RS以参考SSB中的与该SSB index对应SSB的定时为参考来确定CSI-RS的定时信息。如前所述，参考SSB指的是与频点对应的SSB，该频点对应的SSB可能根据发送方向有多个SSB，该多个SSB可以用index标识，那么第一网络设备通过向第二网络设备发送SSB index，使得第二网络设备使用参考SSB中某个方向上的SSB的定时信息来确定定时信息。可以理解的是，当第一网络设备没有向第二网络设备发送上述SSB index信息时，第二网络设备可以以参考SSB中任一个方向上的SSB的定时信息来确定CSI-RS的定时信息。一种可能的方式中，该SSB index信息可以携带在关联SSB(associatedSSB)字段中。通过SSB index的指示，可以进一步确定CSI-RS参考哪个方向上的SSB以获取定时，进一步的，可以在SSB index的基础上指示quasi-colocated(准共址)信息，帮助终端设备更快地获取CSI-RS的发送方向信息，更加容易检测到CSI-RS信号。
可以理解的是，本申请上述各个方法实施例中，由终端设备实现的方法，也可以由可配置于终端设备的部件(例如芯片或者电路)实现，由网络设备(第一网络设备或者第二网络设备)实现的方法，也可以由可配置于网络设备的部件(例如芯片或者电路)实现，由核心网设备实现的方法，也可以由可配置于核心网设备的部件实现。此外，第一网络设备也可以称为第一节点，第二网络设备也可以称为第二节点，核心网设备也可以称为核心网节点。
需要说明的是，在本申请上述各个实施例中，“用于指示”可以包括用于直接指示和用于间接指示。当描述某一指示信息用于指示A时，可以包括该指示信息直接指示A或间接指示A，而并不代表该指示信息中一定包括有A。
将指示信息所指示的信息称为待指示信息，则具体实现过程中，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。同时，还可以识别各个信息的通用部分并统一指示，以降低单独指示同样的信息而带来的指示开销。
此外，在本申请各个实施例中第一、第二以及各种数字编号仅为描述方便进行的区分，并不用来限制本申请实施例的范围。例如，区分不同的频点等。
再者，本申请实施例中涉及的“协议”可以是指通信领域的标准协议，例如可以包括LTE协议、NR协议以及应用于未来的通信***中的相关协议，本申请对此不做限定。
