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。
下面对网络设备和终端设备进行介绍。
(1)网络设备
网络设备包括无线接入网设备(也可以称为接入网设备)，网络设备可以是基站、演进型基站(evolved NodeB，eNodeB)、发送接收点(transmission reception point，TRP)、第五代(5th generation，5G)移动通信系统中的下一代基站(next generation NodeB，gNB)、第六代(6th generation，6G)移动通信系统中的基站、未来移动通信系统中的基站或无线保真(wireless fidelity，WiFi)系统中的接入节点等；也可以是完成基站部分功能的模块或单元，例如，可以是集中式单元(central unit，CU)，也可以是分布式单元(distributed unit，DU)。网络设备可以是宏基站(如图1中的110a)，也可以是微基站或室内站(如图1中的110b)，还可以是中继节点或施主节点等。本申请实施例对网络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。
(2)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。

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接入到无线接入网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，无线接入网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。

上述图1所示意的通信系统可以支持各种无线接入技术(radio access technology，RAT)，例如图1所示意的通信系统可以为第四代(4th generation，4G)通信系统(也可以称为长期演进(long term evolution，LTE)通信系统)，5G通信系统(也可以称为新无线(new radio，NR)通信系统)，6G通信系统，或者是面向未来的演进系统。本申请实施例描述的通信系统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，随着通信系统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。
下面先对本申请实施例所涉及的相关技术特征进行解释说明。需要说明的是，这些解释是为了让本申请实施例更容易被理解，而不应该视为对本申请所要求的保护范围的限定。
(1)SSB的构成
同步信号和物理广播信道(physical broadcast channel，PBCH)块(synchronization signal and PBCH block，SSB)可以包括主同步信号(primary synchronisation signal，PSS)、辅同步信号(secondary synchronisation signal，SSS)和PBCH。如图2a所示，在时域上， 1个SSB占用4个正交频分复用(orthogonal frequency division multiplexing，OFDM)符号(symbol)，为符号0～符号3，在频域上，1个SSB占用20个资源块(resource block，RB)(一个RB包括12个子载波)，也就是240个子载波，子载波编号为0～239。PSS位于符号0的中间的127个子载波上，SSS位于符号2的中间的127个子载波上。为了保护PSS和SSS，分别有不同的保护子载波，保护子载波不用于承载信号，在SSS两侧分别留有子载波作为保护子载波，如图2a中的SSS两侧的空白区域就是保护子载波。PBCH占用符号1和符号3的全部子载波，以及占用符号2的全部子载波中除了SSS所占用的子载波之外的剩余的子载波中的一部分子载波(即剩余的子载波中除了保护子载波之外的子载波)。
其中，PSS可以用于传输小区号，SSS可以用于传输小区组号，小区号和小区组号共同决定了5G通信系统中的多个物理小区号(physical cell identity，PCI)。一旦终端设备成功搜索到了PSS和SSS，也就知道了这个5G载波的物理小区号，从而具备了解析SSB中包含的系统消息的能力。
SSB中的系统消息是由PBCH信道携带的，由于这些信息是终端设备接入网络所必须的信息，因此可以称为主消息块(main information block，MIB)。MIB中可以包含系统帧号、初始接入的子载波间隔，以及其它信息。
由于MIB中包含的信息有限，还不足以支持终端设备接入5G小区。因此终端设备还必须再得到一些必备的系统消息，比如系统信息块(system information block，SIB)1。SIB1以160毫秒为周期在物理下行共享信道(physical downlink shared channel，PDSCH)上传输，由于终端设备已在PBCH所携带的MIB中获取到了SIB1传输所使用的参数以及调度它的控制资源分布情况，因此可以接收SIB1。如此，终端设备可获取到接入5G小区所必须的系统消息，后续可以接入5G小区。
(2)SSB的发送
5G通信系统中，由于网络设备会使用更多天线来增强覆盖，但使用更多天线会导致天线辐射是非常窄的波束，单个窄波束难以覆盖整个小区，同时由于受到硬件限制，网络设备往往不能同时通过多个波束发送信号来覆盖整个小区，因此，5G通信系统引入了波束扫描技术，即网络设备可以在不同时刻通过不同的波束发送信号。比如，针对于一个小区，网络设备可以在不同时刻通过不同的波束发送SSB，来完成小区的广播波束覆盖，如图2b所示。
网络设备在一次波束扫描过程中所发送的SSB的集合可以称为一个同步突发集(synchronization signal burst set，SS burst set)。SS burst set的周期相当于一个特定波束对应的SSB的周期，可以被配置为5ms(毫秒)、10ms、20ms、40ms、80ms或160ms等。由于终端设备在进行小区搜索时，不能在某一个频点上等待过长时间，因此默认按照20ms来进行；如果终端设备在某个频点上等待了20ms的时间，一直未发现SSB，则认为这个频点上不存在5G小区，进而可以转到下一个频点再次尝试。
目前，一个SS burst set周期内最多有4个、8个或64个SSB。当载波频段小于等于3GHz时，一个SS burst set周期内最多有4个SSB。其中，每个SS burst set总是位于5ms的时间间隔内。对于SS burst set的示意可参考图2b，图2b以SS burst set的周期是20ms、且以一个SS burst set包括P个SSB为例。
(3)SSB的时频位置
SSB的时域位置可以是协议规定的，协议规定了不同子载波间隔(subcarrier carrier  space，SCS)和SSB的时域模式(pattern)之间的关系。参见图2c、图2d，这两个图分别表示了SSB的时域pattern。
图2c表示子载波间隔为15KHz时，一个时隙内包括的SSB的一种时域pattern，可以看到，一个时隙包括2个SSB，图2c中画斜线的方框表示SSB占用的符号。
图2d表示子载波间隔为30KHz时，一个时隙内包括的SSB的一种时域pattern，可以看到，一个时隙包括2个SSB，图2d中画斜线的方框表示SSB占用的符号。
在4G通信系统中，SSB可以位于载波中心，由于5G通信系统的系统带宽较大，比如高频能达到400MHz，远大于4G的系统带宽(最大20MHz)，如果像4G通信系统一样把SSB放在载波中心，终端设备在系统带宽的全部频点上来搜索SSB，则会导致终端设备需要的时间较长，而且非常耗电。因此，5G通信系统中不再将SSB放在载波中心，而是放在每个频段中的一些可能位置。进一步地，每个频段可以对应多个频点信息，每个频点信息可以对应多个可能位置(网络设备会在其中一个可能位置上发送SSB)，针对于某一频点信息，终端设备可以按照同步栅格盲检多个可能位置以接收SSB。
由于网络规模越建越大，设备能耗不断上升，网络设备的高能耗逐渐成为运营商运营成本居高不下的主要原因之一。第三代合作伙伴项目(3rd generation partnership project，3GPP)目前有针对网络设备(比如基站)节能的讨论，比如网络设备可以根据负载信息判断是否进行节能操作，例如关断小区。其中，负载信息可以包括无线资源的使用量、用户数量、RRC连接数量等。举个例子，网络设备可以根据负载信息，在夜间关断覆盖办公楼所在区域的小区。但关断小区来降低功耗属于比较粗粒度的节能操作，通常情况下，关断小区的条件较为苛刻，从而导致网络设备很难通过关断小区来降低功耗。
基于此，本申请实施例将对网络设备节能的相关实现进行研究。示例性地，本申请实施例考虑引入细粒度的节能操作，比如针对于一个小区，网络设备可以对小区的SSB采取一些节能操作，以降低网络设备的功耗。
实施例一
在实施例一中，网络设备可以对第一小区的SSB采取节能操作(比如降低第一小区的SSB的发送功率和/或天线增益)，以降低功耗。然而，网络设备对第一小区的SSB采取节能操作，会影响终端设备对SSB的测量结果，从而会导致终端设备测量的第一小区的质量不准确。
具体来说，小区的质量可以是指终端设备在该小区上与网络设备通信的质量。示例性地，小区的质量可以是终端设备通过测量网络设备在该小区上发送的信号所得到的，小区的质量可以包括参考信号接收功率(reference signal receiving power，RSRP)、参考信号接收质量(reference signal receiving quality，RSRQ)和信噪比(signal to interference plus noise ratio，SINR)中的至少一项。比如，对于RRC空闲(RRC_IDLE)态、RRC非激活(Inactive)态的终端设备来说，可以通过测量网络设备在小区上发送的SSB得到该小区的质量。对于RRC连接(RRC_CONNECTED)态的终端设备来说，可以通过测量网络设备在小区上发送的SSB或者信道状态信息参考信号(channel state information-reference signals，CSI-RS)得到该小区的质量。本申请实施例中，将以终端设备通过测量SSB得到小区的质量为例进行描述。
示例性地，终端设备可以根据一个或多个时间点测量得到的SSB的RSRP的平均值， 得到小区的质量。比如，终端设备可以根据第一时间点测量得到的第一SSB的RSRP(称为RSRP1)和第二时间点测量得到的第二SSB的RSRP(称为RSRP2)的平均值，得到小区的质量，即小区的质量等于(RSRP1+RSRP2)/2。
然而，网络设备对SSB采取节能操作(以降低小区的SSB的发送功率为例)，会影响终端设备测量得到的SSB的RSRP，从而会导致终端设备确定的小区的质量不准确。比如，当网络设备未对第一SSB采取节能操作时，网络设备发送第一SSB的发送功率为发送功率1，此时第一SSB的覆盖范围如图3中的(a)所示；当网络设备对第一SSB采取节能操作后，网络设备发送第一SSB的发送功率为发送功率2(发送功率2小于发送功率1)，此时第一SSB的覆盖范围如图3中的(b)所示；由于采取节能操作会导致第一SSB的覆盖范围变小，从而会导致采取节能操作后终端设备测量得到的SSB的RSRP变小。具体来说，当网络设备未对第一SSB采取节能操作时，终端设备测量得到的第一SSB的RSRP为RSRP1，而当网络设备对第一SSB采取节能操作时，终端设备测量得到的第一SSB的RSRP为RSRP1’，RSRP1’小于RSRP1，此时，终端设备确定的小区的质量等于(RSRP1’+RSRP2)/2。因此，当终端设备根据RSRP1’和RSRP2的平均值确定的小区的质量时，会导致小区的质量不准确。
基于此，本申请实施例提供一种通信方法，下面结合图4对该方法进行描述。
图4为本申请实施例一提供的通信方法所对应的流程示意图。如图4所示，该方法包括：
S401，网络设备确定第一小区的节能信息，第一小区的节能信息用于指示第一节能状态对应的补偿值。
此处，第一小区可以为网络设备管理的多个小区中的任一个小区。
下面结合实现方式1和实现方式2对第一小区的节能信息进行描述。
(1)实现方式1
第一小区可以配置有一种节能状态，该节能状态即为第一节能状态。第一小区的节能信息可以用于指示第一节能状态对应的至少一个补偿值，至少一个补偿值中的每个补偿值可以关联第一小区的至少一个SSB。补偿值用于对该补偿值关联的SSB的测量值进行补偿，补偿值的单位可以为分贝(dB)。
比如情形1，第一小区的所有SSB可以关联同一补偿值(称为补偿值a)，此种情形下，第一节能状态可以对应一个补偿值(即补偿值a)。其中，第一小区的所有SSB可以是指第一小区的同步信号突发集中的所有SSB，或者网络设备在第一小区上实际传输的所有SSB(实际传输的SSB可以为同步信号突发集中的部分或全部SSB)。又比如情形2，第一小区的每个SSB可以关联一个补偿值，此种情形下，第一节能状态可以对应多个补偿值。
参见表1，以第一小区的SSB包括SSB0、SSB1、SSB2和SSB3为例，在情形1中，SSB0、SSB1、SSB2和SSB3均关联补偿值a；在情形2中，SSB0关联补偿值b0，SSB1关联补偿值b1，SSB2关联补偿值b2，SSB3关联补偿值b3。其中，补偿值b0、补偿值b1、补偿值b2和补偿值b3中的任意两个补偿值可以相同，或者也可以不同。
表1：一种节能状态对应的补偿值
可以理解的是，上述情形1和情形2仅为示例性说明，还可以存在其它可能的情形，比如SSB0和SSB1关联同一补偿值，SSB2和SSB3关联同一补偿值。
(2)实现方式2
第一小区可以配置有多种节能状态，多种节能状态包括第一节能状态。第一小区的节能信息可以用于指示多种节能状态中每种节能状态对应的至少一个补偿值，至少一个补偿值中的每个补偿值可以关联第一小区的至少一个SSB。比如，多种节能状态包括深度节能状态和轻度节能状态，则第一节能状态可以为深度节能状态，或者也可以为轻度节能状态。其中，针对于某一SSB(比如SSB0)，轻度节能状态下SSB0关联的补偿值可以小于深度节能状态下SSB0关联的补偿值；或者说，轻度节能状态下SSB0的发送功率大于深度节能状态下SSB0的发送功率。
参见表2，以第一小区的SSB包括SSB0、SSB1、SSB2和SSB3为例。针对于深度节能状态，在情形1中，SSB0、SSB1、SSB2和SSB3均关联补偿值a；在情形2中，SSB0关联补偿值b0，SSB1关联补偿值b1，SSB2关联补偿值b2，SSB3关联补偿值b3。针对于轻度节能状态，在情形1中，SSB0、SSB1、SSB2和SSB3均关联补偿值c；在情形2中，SSB0关联补偿值d0，SSB1关联补偿值d1，SSB2关联补偿值d2，SSB3关联补偿值d3。
表2：多种节能状态对应的补偿值
S402，网络设备向终端设备发送第一小区的节能信息。
此处，网络设备向终端设备发送第一小区的节能信息的方式可以有多种，比如网络设备可以向终端设备发送第一小区的系统消息，系统消息中包括节能信息。
S403，终端设备接收第一小区的节能信息，进而当第一小区处于第一节能状态时，可以根据第一节能状态对应的补偿值对SSB的测量值进行补偿。
此处，以SSB0关联的补偿值为补偿值a为例，终端设备根据第一节能状态对应的补偿值对SSB0的测量值进行补偿，可以是指，终端设备将SSB0的测量值和补偿值a相加；也就是说，补偿后的SSB0的测量值等于SSB0的测量值和补偿值a之和。比如，终端设备可以对多个SSB的测量值进行补偿，进而根据补偿后的多个SSB的测量值的平均值得到第一小区的质量；进一步地，终端设备还可以向网络设备发送第一小区的质量(如果终端设备处于连接态，则网络设备可以根据终端设备上报的第一小区的质量，判断是否将终端设备切换到第一小区以外的其它小区)。
其中，终端设备确定第一小区处于第一节能状态的方式可以有多种。作为一种可能的实现，在S502之后，网络设备可以向终端设备发送第一指示信息，第一指示信息指示第一小区处于第一节能状态，进而终端设备可以根据第一指示信息确定第一小区处于第一节能状态。比如，网络设备可以在确定第一小区的负载满足预设条件后，向终端设备发送第一指示信息。其中，第一小区的负载满足预设条件可以是指第一小区的无线资源的使用量 小于或等于第一阈值，或者也可以是指第一小区的RRC连接数量小于或等于第二阈值，第一阈值和第二阈值可以为协议预先定义的，具体不做限定。
示例性地，第一指示信息可以包括以下至少一项：第一节能状态的标识；第一小区处于第一节能状态的起始时间信息；第一小区处于第一节能状态的时长；第一小区处于第一节能状态的结束时间信息；第一小区处于第一节能状态的频率范围信息。下面分别对这几项信息进行详细说明。
(1)第一节能状态的标识
当第一小区配置有多种节能状态时，第一指示信息可以包括第一节能状态的标识。当第一小区仅配置一种节能状态(即第一节能状态)时，第一指示信息也可以不包括第一节能状态的标识。
(2)第一小区处于第一节能状态的起始时间信息
第一指示信息可以包括第一小区处于第一节能状态的起始时间信息，进而终端设备可以根据起始时间信息确定第一小区何时进入第一节能状态。或者，第一指示信息也可以不包括第一小区处于第一节能状态的起始时间信息，此种情形下，终端设备可以根据第一指示信息的接收时间来确定第一小区何时进入第一节能状态，比如第一指示信息的接收时间即为第一小区处于第一节能状态的起始时间。
示例性地，第一小区处于第一节能状态的起始时间信息用于指示第一小区处于第一节能状态的起始时隙和/或起始符号。比如，起始时间信息包括起始时隙的编号和/或起始符号的编号。
(3)第一小区处于第一节能状态的时长、第一小区处于第一节能状态的结束时间信息
第一指示信息可以包括第一小区处于第一节能状态的时长和/或第一小区处于第一节能状态的结束时间信息，以便于终端设备确定第一小区何时结束第一节能状态。或者，第一指示信息也可以不包括第一小区处于第一节能状态的时长和第一小区处于第一节能状态的结束时间信息，此种情形下，网络设备可以向终端设备发送第二指示信息，终端设备可以根据第二指示信息的接收时间来确定第一小区何时结束第一节能状态，比如第二指示信息的接收时间即为第一小区处于第一节能状态的结束时间。
示例性地，第一小区处于第一节能状态的时长的单位可以为时隙或者符号或者其它可能的时间单位，具体不做限定。第一小区处于第一节能状态的结束时间信息用于指示第一小区处于第一节能状态的结束时隙和/或结束符号。比如，结束时间信息包括结束时隙的编号和/或结束符号的编号。
(4)第一小区处于第一节能状态的频率范围信息
第一小区处于第一节能状态的频率范围信息用于指示第一小区处于第一节能状态的频率范围，比如频率范围信息可以包括该频域范围对应的起始物理资源块(physical resource block，PRB)的编号和结束PRB的编号。
第一指示信息可以包括第一小区处于第一节能状态的频率范围信息，此种情形下，若终端设备在该频率范围内接收到第一小区的SSB，则可以根据SSB关联的补偿值对SSB的测量值进行补偿；若终端设备在该频域范围以外接收到第一小区的SSB，则可以无需对SSB的测量值进行补偿。或者，第一指示信息也可以不包括第一小区处于第一节能状态的频率范围信息，此种情形下，终端设备若接收到第一小区的SSB，便可以根据SSB关联的 补偿值对SSB的测量值进行补偿。
可以理解的是，网络设备向终端设备发送第一指示信息的方式可以有多种。比如，网络设备可以向终端设备发送DCI，DCI中可以包括第一指示信息的所有信息，或者DCI中可以包括第一指示信息的部分信息，此种情形下，网络设备可以通过系统消息向终端设备发送第一指示信息的另一部分信息。在一个示例中，第一指示信息的部分信息可以包括以下至少一项：第一节能状态的标识、第一小区处于第一节能状态的起始时间信息；第一指示信息的另一部分信息可以包括以下至少一项：第一小区处于第一节能状态的时长；第一小区处于第一节能状态的结束时间信息；第一小区处于第一节能状态的频率范围信息。此外，如果终端设备处于空闲态或非激活态，则上述DCI可以为用于寻呼终端设备的DCI；也就是说，网络设备可以通过寻呼终端设备，以通知终端设备第一小区处于第一节能状态。
采用上述实施例一中的方法，网络设备可以向终端设备发送第一小区的节能信息，第一小区的节能信息用于指示第一节能状态对应的补偿值；进而，当第一小区处于第一节能状态时，终端设备可以根据补偿值对补偿值关联的SSB的测量值进行补偿，补偿后的SSB的测量值可以用于确定小区的质量，从而能够在降低网络设备的功耗的同时，提高终端设备确定的小区的质量的准确性。
实施例二
在实施例二中，网络设备可以关断第一小区的部分SSB，以降低功耗。然而，当网络设备关断第一小区的部分SSB后，如果终端设备仍然测量这部分SSB，则一方面会导致终端设备进行了多余的测量，另一方面如果终端设备根据这部分SSB的测量结果来确定第一小区的质量，会导致第一小区的质量不准确。
基于此，本申请实施例提供一种通信方法，下面结合图5对该方法进行描述。
图5为本申请实施例二提供的通信方法所对应的流程示意图。如图5所示，该方法包括：
S501，网络设备确定第三指示信息，第三指示信息指示第一小区的M个SSB处于关断状态，M为正整数。
此处，M个SSB可以为第一小区的部分或全部SSB。示例性地，第三指示信息可以包括M个SSB的索引，此种情形下，M个SSB的索引可以是连续的，或者也可以是不连续的。或者，第三指示信息包括以下至少一项：M个SSB中第一个SSB的索引、M的取值、M个SSB中最后一个SSB的索引；此种情形下，M个SSB的索引是连续的。其中，M个SSB中第一个SSB是指M个SSB中索引值最小的SSB，M个SSB中最后一个SSB是指M个SSB中索引值最大的SSB。
示例性地，第三指示信息还可以指示第一时间段，M个SSB在第一时间段内处于关断状态。比如，第一时间段包括以下至少一项：第一同步突发集周期，第一同步突发集周期为第三指示信息的接收时间所在的同步突发集周期；连续K个同步突发集周期，K个同步突发集周期中的首个同步突发集周期为第一同步突发集周期的下一个同步突发集周期，K为正整数。其中，第三指示信息指示第一时间段的方式可以有多种，具体不做限定。
S502，网络设备向终端设备发送第三指示信息。
示例性地，网络设备可以在确定第一小区的负载满足预设条件后，确定需要关断的M个SSB(即确定第三指示信息)，并向终端设备发送第三指示信息。其中，第一小区的负 载满足预设条件的描述可以参照实施例一。
其中，网络设备向终端设备发送第三指示信息的方式可以有多种。作为一种可能的实现，网络设备可以向终端设备发送DCI，即第三指示信息可以承载于DCI。此外，如果终端设备处于空闲态或非激活态，则DCI可以为用于寻呼终端设备的DCI，也就是说，网络设备可以通过寻呼终端设备，以通知终端设备M个SSB处于关断状态。
作为一种可能的实现，第一小区的SSB可以分为两种类型的SSB，第一类型的SSB为不允许动态关断的SSB，第二类型的SSB为允许动态关断的SSB；此种情形下，M个SSB可以为第二类型的SSB中的部分或全部SSB。其中，划分第一类型和第二类型的SSB的依据可以有多种，本申请实施例对此不做限定。
进一步可选地，在上述S501之前，网络设备可以向终端设备发送第四指示信息，第四指示信息指示允许动态关断的第一小区的N个SSB，M个SSB属于N个SSB，N为正整数。也就是说，网络设备可以先通过第四指示信息向终端设备指示N个SSB是允许动态关断的，然后再通过第三指示信息动态地向终端设备指示实际关断的M个SSB。网络设备向终端设备发送第四指示信息的方式可以有多种，比如，网络设备可以向终端设备发送第一小区的系统消息，系统消息中包括第四指示信息，即第四指示信息可以承载于第一小区的系统消息。
S503，终端设备接收第三指示信息，并在M个SSB处于关断状态时，不对M个SSB进行测量，或者即使对M个SSB进行了测量，终端设备也认为测量结果是无效的。
示例性地，网络设备可以在第一时频资源上向终端设备发送PDSCH，第一时频资源包括关断的M个SSB中至少一个SSB对应的时频资源；也就是说，网络设备可以使用关断的SSB对应的时频资源来向终端设备发送PDSCH，从而提高资源利用率。进一步地，网络设备在第一时频资源上向终端设备发送PDSCH之前，可以先向终端设备发送DCI，DCI用于指示第一时频资源，进而终端设备可以根据DCI，在第一时频资源上接收PDSCH，参见图6所示。可以理解的是，如果SSB不关断，则终端设备是在SSB的资源上接收SSB，而不会接收PDSCH。
采用上述实施例二中的方法，网络设备可以关断第一小区的M个SSB，从而便于降低网络设备的功耗；以及，网络设备可以向终端设备发送第三指示信息，第三指示信息指示第一小区的M个SSB处于关断状态，进而，终端设备可以根据第三指示信息，在M个SSB处于关断状态时不对M个SSB进行测量，从而能够有效降低终端设备的功耗，或者即使对M个SSB进行了测量，也认为测量结果是无效的，从而能够有效避免终端设备确定的小区的质量不准确。
实施例三
在实施例三中，网络设备可以配置多种SSB传输模式，并在多种SSB传输模式之间动态切换，以降低功耗。下面结合图7进行详细描述。
图7为本申请实施例三提供的通信方法所对应的流程示意图。如图7所示，该方法包括：
S701，网络设备确定第一小区的多种SSB传输模式的配置信息。
S702，网络设备向终端设备发送多种SSB传输模式的配置信息；相应地，终端设备可以接收多种SSB传输模式的配置信息。
示例性地，多种SSB传输模式包括第一SSB传输模式，第一SSB传输模式的配置信息包括以下至少一项：第一SSB传输模式对应的SSB的索引；第一SSB传输模式对应的同步突发集周期。可以理解的是，第一SSB传输模式的配置信息还可以包括其它可能的信息，具体不做限定。
举个例子，多种SSB传输模式包括第一SSB传输模式和第二SSB传输模式。其中，第一SSB传输模式对应的SSB的索引可以包括SSB0、SSB1，第二SSB传输模式对应的同步突发集周期为20ms；第二SSB传输模式对应的SSB的索引可以包括SSB0、SSB1、SSB2、SSB3，第二SSB传输模式对应的同步突发集周期为10ms。
S703，网络设备向终端设备发送第五指示信息，第五指示信息指示在第一小区上采用第一SSB传输模式，进而网络设备可以根据第一SSB传输模式在第一小区上发送SSB；相应地，终端设备可以接收第五指示信息，并根据第一SSB传输模式在第一小区上接收SSB。
示例性地，网络设备向终端设备发送第五指示信息的方式可以有多种。作为一种可能的实现，网络设备可以向终端设备发送DCI，即第五指示信息可以承载于DCI。此外，如果终端设备处于空闲态或非激活态，则DCI可以为用于寻呼终端设备的DCI，也就是说，网络设备可以通过寻呼终端设备，以通知终端设备在第一小区上采用的SSB传输模式。
其中，第五指示信息指示在第一小区上采用第一SSB传输模式的方式可以有多种，比如第五指示信息包括第一SSB传输模式的标识。
比如，当网络设备采用第二SSB传输模式向终端设备发送SSB时，如果网络设备确定第一小区的负载满足预设条件时，则可以向终端设备发送第五指示信息，第五指示信息指示网络设备在第一小区上使用的SSB传输模式切换为第一SSB传输模式。由于第一SSB传输模式对应的同步突发集周期大于第二SSB传输模式对应的同步突发集周期，且第一SSB传输模式对应的SSB个数小于第二SSB传输模式对应的SSB个数，因此，从第二SSB传输模式切换为第一SSB传输模式，能够有效网络设备的降低功耗。
针对于上述实施例一至实施例三，可以理解的是：
