具体实施方式
本申请实施例描述的网络架构以及业务场景是为了更加清楚的说明本申请实施例的技术方案，并不构成对于本申请实施例提供的技术方案的限定，本领域普通技术人员可知，随着网络架构的演变和新业务场景的出现，本申请实施例提供的技术方案对于类似的技术问题，同样适用。
本申请实施例既可以应用于时分双工(time division duplexing，TDD)的场景，也可以适用于频分双工(frequency division duplexing，FDD)的场景。本申请实施例 以无线通信网络中第五代(5th generation，5G)通信网络的场景进行举例说明，应当指出的是，本申请实施例中的方案还可以应用于其他无线通信网络中，相应的名称也可以用其他无线通信网络中的对应功能的名称进行替代。
本申请实施例提供了一种通信***，参照图1中所示，包括至少一个终端(terminal)11、第一网络设备12和第二网络设备13。
可选的，本申请实施例中所涉及到的终端11可以包括各种具有无线通信功能的手持设备、车载设备、可穿戴设备、计算设备或连接到无线调制解调器的其他处理设备；还可以包括用户单元(subscriber unit)、蜂窝电话(cellular phone)、智能电话(smart phone)、无线数据卡、个人数字助理(personal digital assistant，PDA)电脑、平板型电脑、无线调制解调器(modem)、手持设备(handheld)、膝上型电脑(laptop computer)、无绳电话(cordless phone)或者无线本地环路(wireless local loop，WLL)台、机器类型通信(machine type communication，MTC)终端、用户设备(user equipment，UE)、移动台(mobile station，MS)、终端设备(terminal device)或者中继用户设备等。其中，中继用户设备例如可以是5G家庭网关(residential gateway，RG)。为方便描述，上面提到的设备可以统称为终端。
以终端11为手机为例，对手机的硬件架构进行说明。如图2所示，手机可以包括：射频(radio frequency，RF)电路110、存储器120、其他输入设备130、显示屏140、传感器150、音频电路160、I/O子***170、处理器180、以及电源190等部件。本领域技术人员可以理解，图中所示的手机的结构并不构成对手机的限定，可以包括比图示更多或者更少的部件，或者组合某些部件，或者拆分某些部件，或者不同的部件布置。本领域技术人员可以理解显示屏140属于用户界面(user interface，UI)，显示屏140可以包括显示面板141和触摸面板142。尽管未示出，手机还可以包括摄像头、蓝牙模块等功能模块或器件，在此不再赘述。
进一步地，处理器180分别与RF电路110、存储器120、音频电路160、I/O子***170、以及电源190连接。I/O子***170分别与其他输入设备130、显示屏140、传感器150连接。其中，RF电路110可用于在收发信息或通话过程中对信号的接收和发送，特别地，接收来自网络设备的下行信息后，发送给处理器180处理。存储器120可用于存储软件程序以及模块。处理器180通过运行存储在存储器120的软件程序以及模块，从而执行手机的各种功能应用以及数据处理，例如执行本申请实施例中终端的方法和功能。其他输入设备130可用于接收输入的数字或字符信息，以及产生与手机的用户设置以及功能控制有关的键盘信号输入。显示屏140可用于显示由用户输入的信息或提供给用户的信息以及手机的各种菜单，还可以接受用户输入。传感器150可以为光传感器、运动传感器或者其他传感器。音频电路160可提供用户与手机之间的音频接口。I/O子***170用来控制输入输出的外部设备，外部设备可以包括其他设备输入控制器、传感器控制器、显示控制器。处理器180是手机11的控制中心，利用各种接口和线路连接整个手机的各个部分，通过运行或执行存储在存储器120内的软件程序和/或模块，以及调用存储在存储器120内的数据，执行手机11的各种功能和处理数据，从而对手机进行整体监控。电源190(比如电池)用于给上述各个部件供电，优选的，电源可以通过电源管理***与处理器180逻辑相连，从而通过电源管理 ***实现管理充电、放电、以及功耗等功能。在本申请实施例中终端11可以通过RF电路110从第二网络设备13接收同步信号块的配置信息。
如图3所示，本申请实施例中所涉及到的网络设备可以是RAN中的基站(如gNB)等。基站可以是集中式单元(centralized unit，CU)和分布式单元(distributed unit，DU)分离架构。RAN可以与核心网相连(例如可以是长期演进(long term evolution，LTE)的核心网，也可以是5G的核心网等)。CU和DU可以理解为是对基站从逻辑功能角度的划分。CU和DU在物理上可以是分离的也可以部署在一起。多个DU可以共用一个CU。一个DU也可以连接多个CU(图中未示出)。CU和DU之间可以通过接口相连，例如可以是F1接口。CU和DU可以根据无线网络的协议层划分。例如其中一种可能的划分方式是：CU用于执行无线资源控制(radio resource control，RRC)层、业务数据适配协议(service data adaptation protocol，SDAP)层以及分组数据汇聚层协议(packet data convergence protocol，PDCP)层的功能，而DU用于执行无线链路控制(radio link control，RLC)层，媒体接入控制(media access control，MAC)层，物理(physical)层等的功能。可以理解对CU和DU处理功能按照这种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。例如，CU或DU还可以划分为具有协议层的部分处理功能。在一设计中，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。在另一种设计中，还可以按照业务类型或者其他***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。图3所示的网络架构可以应用于5G通信***，其也可以与LTE***共享一个或多个部件或资源。在另一种设计中，CU也可以具有核心网的一个或多个功能。一个或者多个CU可以集中设置，也分离设置。例如CU可以设置在网络侧方便集中管理。DU可以具有多个射频功能，也可以将射频功能拉远设置。
CU的功能可以由一个实体来实现也可以由不同的实体实现。例如，可以对CU的功能进行进一步切分，例如，将控制面(control panel，CP)和用户面(user panel，UP)分离，即CU的控制面(CU-CP)和CU用户面(CU-UP)。例如，CU-CP和CU-UP可以由不同的功能实体来实现，所述CU-CP和CU-UP可以与DU相耦合，共同完成基站的功能。
一种可能的方式中，以第一网络设备12和第二网络设备13为基站为例，对基站的硬件架构进行说明。如图4所示，基站12可以包括室内基带处理单元(building baseband unit，BBU)1201和远端射频模块(remote radio unit，RRU)1202，RRU 1202和天馈***(即天线)1203连接，BBU 1201和RRU 1202可以根据需要拆开使用。天线1203可以为天线阵列，包括多个子天线即阵元，基站可以通过码本将天线域的信号处理转换为波束域信号，并且对这些阵元的方向角进行控制，本申请实施例中基站可以控制一部分阵元采用固定码本调制，另一部分采用随机码本调制。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，接入点等。本申请实施例所述的第一网络设备12与第二网络设备13相互之间可以通过RRU 1202和天馈***(即天线)1203交互同步信号块的配置信息，第一网络设备12或第二网络设 备13向终端11配置邻区信息时，可以将同步信号块的配置信息发送给终端11，使得终端11可以仅对小区定义的同步信号块进行测量，降低终端的功耗。
本申请实施例提供了一种通信方法，参照图5中所示，该方法可以包括：
S101、第一网络设备确定第一信息。
其中，第一信息中包括与同步信号块相关的信息。可选的，本申请实施例所述的同步信号块可以是同步信号(synchronization signal，SS)，还可以是同步信号/物理广播信道块(synchronization signal/physical broadcast channel block，SS/PBCH Block)等，本申请实施例不作限定。
一种可能的方式中，本申请实施例所述的同步信号块可以指第一网络设备的第一小区或第一载波中的至少一个同步信号块。可选的，该第一小区可以是一个或多个小区。可选的，该第一载波可以是一个或多个载波。
又一种可能的方式中，同步信号块可以指第二网络设备的第二小区或第二载波中的至少一个同步信号块。可选的，该第二小区可以是一个或多个小区。可选的，该第二载波可以是一个或多个载波。
一个小区或一个载波在频域上可以有多个同步信号块，每个同步信号块对应一个频点。可选的，第一信息可以包括同步信号块的类型信息。一种可能的方式中，第一信息还可以包括同步信号块的频点信息。
在一种可能的实施方式中，同步信号块的类型信息用于指示该同步信号块为小区定义的同步信号块或非小区定义的同步信号块。可以理解的是，如果该同步信号块为小区定义的同步信号块，则表示该同步信号块支持初始接入或驻留或小区重选或小区选择；如果该同步信号块为非小区定义的同步信号块，则该同步信号块不支持初始接入或驻留或小区重选或小区选择。
或者，在另一种可能的实施方式中，同步信号块的类型信息用于指示该同步信号块是否支持初始接入或驻留或小区重选或小区选择。
或者，在又一种可能的实施方式中，同步信号块的类型信息用于指示该同步信号块是否发送基本***信息。在5G通信网络中，此处的基本***信息例如可以是***信息块(system information blocks，SIB)1信息，在4G通信网络中，此处的基本***信息例如可以是SIB1信息和SIB2信息。可选的，如果该同步信号块发送SIB1信息，则该同步信号块支持初始接入或驻留或小区重选或小区选择；如果该同步信号块不发送SIB1信息，则该同步信号块不支持初始接入或驻留或小区重选或小区选择。
可选的，同步信号块类型指示为小区定义的同步信号块或非小区定义的同步信号块，与指示该同步信号块是否支持初始接入或驻留或小区重选或小区选择，或者指示该同步信号块是否发送基本***信息，在效果上可以理解为是等价的。
可选的，可以通过至少1比特来表示同步信号块的类型信息。例如，以该比特值为0表示非小区定义的同步信号块，或者表示该同步信号块不支持初始接入或驻留或小区重选或小区选择，或者表示该同步信号块不发送基本***信息；以该比特值为1表示小区定义的同步信号块，或者表示该同步信号块支持初始接入或驻留或小区重选或小区选择，或者表示该同步信号块发送基本***信息。或者，以该比特值为1表示非小区定义的同步信号块，或者表示该同步信号块不支持初始接入或驻留或小区重选 或小区选择，或者表示该同步信号块不发送基本***信息；以该比特值为0表示小区定义的同步信号块，或者表示该同步信号块支持初始接入或驻留或小区重选或小区选择，或者表示该同步信号块发送基本***信息。可以理解的是，也可以是以该比特值为1或者0表示小区定义的同步信号块，或者表示该同步信号块支持初始接入或驻留或小区重选或小区选择，或者表示该同步信号块发送基本***信息，而对非小区定义的同步信号块，或者不支持初始接入或驻留或小区重选或小区选择的同步信号块，或者不发送基本***信息的同步信号块可以默认不指示；或者，也可以是以该比特值为1或者0表示该同步信号块不支持初始接入或驻留或小区重选或小区选择，或者表示该同步信号块不发送基本***信息，而对小区定义的同步信号块，或者支持初始接入或驻留或小区重选或小区选择的同步信号块，或者发送基本***信息的同步信号块默认不指示。本申请实施例对指示同步信号块类型的方式不做限定。
上述第一信息便于帮助终端避免在所有频点上盲目搜索过程，仅测量可供初始接入或驻留或小区重选或小区选择的同步信号块(即小区定义的同步信号块)，可以降低终端进行初始接入或驻留或小区重选或小区选择时测量同步信号块的功耗。
可选地，在另一种可能的方式中，第一信息可以包括所指示的至少一个同步信号块的偏移(offset)/索引(index)信息，结合已有频点信息以及偏移(offset)/索引(index)信息可以确定所指示的至少一个同步信号块的频点信息。
可选的，第一信息还可以包括辅助配置信息，辅助配置信息可以包括用于指示同步信号块的频域上的子载波大小的信息、同步信号块的测量信息、用于指示邻区或邻区的同步信号块是否与服务小区或服务同步信号块定时同步的信息、用于判断同步信号块是否时域同步的信息中的任意一种或者任意组合。可以理解的是，第一信息可以包括上述辅助配置信息和同步信号块的类型信息的至少一种，本申请实施例对此不做限定。可选的，第一信息可以通过已有的消息或专门的消息发送，例如第一信息可以是属于配置信息。
其中，同步信号块的测量信息用于指示同步信号块在时域的位置。例如可以包括同步信号块在时域上的测量周期、测量窗口、起始时间、相对偏移、测量时长的至少一种。而用于判断同步信号块是否时域同步的信息可以包括***帧号(system frame number，SFN)和/或时间标记信息。
上述同步信号块的辅助配置信息便于帮助终端进一步快速确定同步信号块的位置，从而可以缩短搜索过程，可以降低终端进行初始接入或驻留或小区重选或小区选择时测量同步信号块的功耗。
一种可能的方式中，上述辅助配置信息也可以独立于同步信号块的类型信息，也就是说，在本申请的一个实施例中，第一信息可以包括辅助配置信息，但不包括同步信号块的类型信息。
可以理解的是，第一网络设备可以根据资源使用信息或者其他信息确定第一信息。可选的，本申请实施例所述的资源使用信息可以包括以下信息的至少一种：负载信息、物理资源块利用率、拥塞信息、承载的用户量。本申请实施例对如何确定第一信息的方式不做限定。
S102、第一网络设备向第二网络设备发送上述第一信息。
在一种可能的实施方式中，第一网络设备与第二网络设备均为基站。也就是说，第一网络设备和第二网络设备之间的交互是基站间的交互。可选的，第一网络设备是与第二网络设备存在Xn接口的至少一个网络设备。第二网络设备是为终端提供服务的网络设备。
在另一种可能的实施方式中，第一网络设备为CU，第二网络设备为DU；或者，第一网络设备为DU，第二网络设备为CU。也就是说，第一网络设备和第二网络设备之间的交互是CU和DU之间的交互。可选的，第一网络设备是与第二网络设备存在F1接口的至少一个网络设备。
以第一网络设备与第二网络设备均为基站为例，基站间建立Xn连接的过程中，可以交互各基站的小区信息或载波信息。比如，小区信息可以是本基站小区的小区全局标识(cell global identifier，CGI)、物理小区标识(physical cell identifier，PCI)、频点信息的至少一种等。比如，载波信息可以是本基站载波的频点信息、频域带宽信息的至少一种等。

可以理解的是，第二网络设备可以从至少一个第一网络设备处接收第一信息。
可选的，参照图5中所示，上述方法还可以包括步骤S103、或S103和S104：
S103、第二网络设备发送第二信息。
可选地，第二信息由第二网络设备发出，相应的，终端会接收到上述第二信息。
可以理解的是，第二信息是根据第一信息确定的，可以包括与同步信号块相关的信息。可选的，该第二信息中还可以包括步骤S101中所述的辅助配置信息。第二网络设备接收到第一信息后，可以通过多种不同的实现方式向终端发送第二信息，例如以下方式(1)或者方式(2)中任意一种，本申请实施例对此不作限定。
方式(1)、第二信息可以用于指示至少一个同步信号块。在一种可能的方式中，第二信息可以包括所指示的至少一个同步信号块的频点信息。在另一种可能的方式中，第二信息可以包括所指示的至少一个同步信号块的偏移(offset)/索引(index)信息，结合已有频点信息以及偏移(offset)/索引(index)信息可以确定所指示的至少一个同步信号块的频点信息。
可以理解的是，此处第二信息中指示的至少一个同步信号块可以均为小区定义的同步信号块。如前所述，小区定义的同步信号块也可以称为支持初始接入或驻留或小区重选或小区选择的同步信号块，或者也可以称为发送基本***信息的同步信号块。可以理解的是，此处第二信息指示的至少一个同步信号块可以包括终端的服务小区的同步信号块和/或服务小区的相邻小区的同步信号块。该第二信息可以根据第一信息确定。其中，服务小区的相邻小区可以是服务小区的同频或者异频或者异***的相邻小区。例如，根据第一信息，第二网络设备可以获知哪些同步信号块是小区定义的同步信号块，从而将用于指示这些同步信号块的信息(例如频点信息)发送给终端。
通过上述方式，第二网络设备向终端发送小区定义的同步信号块的频点信息而非全部同步信号块的频点信息，使得终端在进行初始接入或驻留或小区重选或小区选择 时可以直接对这些频点的同步信号块进行测量，以降低终端在进行初始接入或驻留或小区重选或小区选择时测量同步信号块的功耗。
方式(2)、第二信息中可以包括至少一个同步信号块的频点信息和类型信息。
如前文所述，可以通过1比特来表示同步信号块的类型信息。例如，以0表示非小区定义的同步信号块，或者表示该同步信号块不支持初始接入或驻留或小区重选或小区选择，或者表示该同步信号块不发送基本***信息；以1表示小区定义的同步信号块；或者，以1表示非小区定义的同步信号块，以0表示小区定义的同步信号块。作为一种可能的实施方式，可以在服务小区向终端发送的邻区信息(neighbour information)中可以包括相邻小区的小区信息或载波信息以及相邻小区的至少一个同步信号块的频点信息和类型信息。其中，相邻小区的小区信息可以包括E-UTRAN小区全局标识符(E-UTRAN cell global identifier，ECGI)、物理小区标识(physical cell identifier，PCI)的至少一种。相邻小区的载波信息可以包括频点信息、载波带宽的至少一种。一种示例性的实施方式如表1所示，其指示的邻区信息包括相邻小区的小区信息以及相邻小区的同步信号块的频点信息和类型信息。

其中，NR ARFCN表示同步信号块的频点信息。本实施例中，以SSB的频点信息为ARFCN为例。具体地，表1中的NR ARFCN和SSB是对应的。可选地，SSB的频点信息还可以称为全局同步信道编号(global sync raster channel number，GSCN)。从表中可以看出，SSB1的频点的同步信号块的类型信息为1，可以表示该频点的同步信号块为小区定义的同步信号块；SSB2的频点的同步信号块的类型信息为0，可以表示该频点的同步信号块为非小区定义的同步信号块。
在另一种可能的方式中，第二信息可以包括所指示的至少一个同步信号块的偏移(offset)/索引(index)信息和类型信息，结合已有频点信息以及偏移(offset)/索引(index)信息可以确定所指示的至少一个同步信号块的频点信息。
第二信息是根据第一信息确定的。例如，第二网络设备可以是将第一信息传递给终端，或者第二网络设备根据第一信息处理后，将需要通知到终端的同步信号块的信息传递给终端，本申请实施例对此不做限定。
可以理解的是，第二信息所指示的同步信号块可以包括第一信息所指示的同步信 号块全部或者部分，本申请实施例对此不做限定。本申请实施例中，可以将第一信息所指示的同步信号块称为第一同步信号块，将第二信息所指示的同步信号块称为第二同步信号块。
可以理解的是，可选的，第二信息可以通过已有的消息或专门的消息发送，本申请实施例对此不做限定。
S104、终端对小区定义的同步信号块进行测量。
