Description

通信的方法、通信装置

技术领域
本申请涉及通信领域，并且，更具体地，涉及通信的方法和装置。
背景技术
在通信过程中，基站的功耗主要由功放功耗、射频功耗以及室内基带处理单元的功耗组成。随着收发信机的链路增加，基站总功耗成倍增加。因此可以通过符号关断方式来降低功耗，实现节能。
然而，在一些场景下，如新无线(New radio，NR)系统，考虑到同步信号/物理广播信道块(Synchronization signal/physical broadcast channel block，SS/PBCH block)消息、系统信息块、寻呼消息等需要一直传输，占据了大量的下行发送时隙，因此导致基站无法通过符号关断方式进行节能。
发明内容
本申请提供一种通信的方法和装置，能够通过多个同覆盖的不同频段小区的协作配合，减小系统广播消息发送的数量，预留更多下行时隙以达到节能的目的。

示例地，第一频率范围内的小区进入节能状态后，停止发送RMSI/OSI/Paging消息，和/或，只发送SSB消息。
示例地，第一频率范围内的小区可以表示容量层的小区；第二频率范围内的小区可以表示覆盖层的小区。
基于上述技术方案，在第一频率范围内的小区节能状态下，终端设备可以在第二频率范围内的小区的协助下接入第一频率范围内的小区。因此，第一频率范围内的小区既可以进入节能状态，而且也可以在第二频率范围内的小区的协助下，不失正常通信能力的同时，能够达到协同节能的效果。

基于上述技术方案，驻留和初始接入功能可以由第二频率范围内的小区负载。终端设备接入到第二频率范围内的小区后，可以通过第二频率范围内的小区的协助接入到第一频率范围内的小区。因此，第一频率范围内的小区既可以进入节能状态，而且也可以在第二频率范围内的小区的协助下，不失正常通信能力的同时，能够达到协同节能的效果。
结合第二方面，在第二方面的某些实现方式中，所述第一频率范围内的小区进入节能状态，包括：所述第一频率范围内的小区不支持驻留和初始接入功能。

具体实施方式
下面将结合附图，对本申请中的技术方案进行描述。
本申请实施例的技术方案可以应用于各种通信系统，例如：第五代(5th generation，5G)系统或NR系统、长期演进(long term evolution，LTE)系统、LTE频分双工(frequency division duplex，FDD)系统、LTE时分双工(time division duplex，TDD)、通用移动通信系统(universal mobile telecommunication system，UMTS)等。
图1是适用于本申请实施例的无线通信系统100的一示意图。如1图所示，该无线通信系统100可以包括至少一个网络设备，例如图1所示的网络设备111，该无线通信系统100还可以包括至少一个终端设备，例如图1所示的终端设备121至终端设备123。网络设备和终端设备均可配置多个天线，网络设备与终端设备可使用多天线技术通信。
其中，网络设备和终端设备通信时，网络设备可以管理一个或多个小区，一个小区中可以有整数个终端设备。可选地，网络设备111和终端设备121至终端设备123组成一个单小区通信系统，不失一般性，将小区记为小区#1。网络设备111可以是小区#1中的网络设备，或者说，网络设备111可以为小区#1中的终端设备(例如终端设备121)服务。
需要说明的是，小区可以理解为网络设备的无线信号覆盖范围内的区域。
图2是适用于本申请实施例的无线通信系统200的另一示意图。如图2所示，该无线通信系统200可以包括一个终端设备，例如图2中的终端设备221；该无线通信系统200还可以多个网络设备，例如图2中的网络设备211和网络设备212。图2中的终端设备221可以同时与网络设备221和网络设备212进行通信；或者说，网络设备211和网络设备212可以联合为终端设备221提供服务。
图3为适用于本申请的一种系统架构图。其中，该架构例如可以包括室内基带处理单元(building base band unite，BBU)和有源天线处理单元(active antenna unit,AAU)组成。
图4为适用于本申请的一种移动通信系统框架图。如图所示，在移动通信系统中，网络设备功耗，如基站功耗，由功率放大器(power amplifier,PA)功耗、射频(radio frequency,RF)功耗和BBU功耗组成，并随着收发信机(transceiver,TRX)链路增加，基站总功耗成倍增加。比如，大规模天线(Massive MIMO)的天线单元越多，每个天线单元都有PA和RF单元，TRX链路增加，同时BBU的计算功耗也随着TRX链路增加而上升，因此基站总功耗随之上升。通过符号关断原理可以解决上述问题，具体的下文说明。
应理解，上述图1至图4仅是示例性说明，本申请并未限定于此。例如，本申请实施 例还可以应用于随机接入场景(如5G NR随机接入过程)。
在本申请实施例，第一频率范围内的小区和第二频率范围内的小区可以都为一个网络设备中的小区，比如都为图1中网络设备111中的小区。或者，第一频率范围内的小区和第二频率范围内的小区可以为不同网络设备中的小区，比如第一频率范围内的小区为图2中网络设备112，第二频率范围内的小区为图2中网络设备113的小区。
应理解，该无线通信系统中的网络设备可以是任意一种具有无线收发功能的设备。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(例如，Home evolved NodeB，或Home Node B，HNB)、基带单元(BaseBand Unit，BBU)，无线保真(Wireless Fidelity，WIFI)系统中的接入点(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，系统中的gNB，或，传输点(TRP或TP)，5G系统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。
在一些部署中，gNB可以包括集中式单元(centralized unit，CU)和DU。gNB还可以包括有源天线单元(active antenna unit，简称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。
还应理解，该无线通信系统中的终端设备也可以称为用户设备(user equipment，UE)、接入终端、用户单元、用户站、移动站、移动台、远方站、远程终端、移动设备、用户终端、终端、无线通信设备、用户代理或用户装置。本申请的实施例中的终端设备可以是手机(mobile phone)、平板电脑(Pad)、带无线收发功能的电脑、虚拟现实(virtual reality，VR)终端设备、增强现实(augmented reality，AR)终端设备、工业控制(industrial control)中的无线终端、无人驾驶(self driving)中的无线终端、远程医疗(remote medical)中的无线终端、智能电网(smart grid)中的无线终端、运输安全(transportation safety)中的无线终端、智慧城市(smart city)中的无线终端、智慧家庭(smart home)中的无线终端等等。本申请的实施例对应用场景不做限定。
为便于理解本申请实施例，下面首先对本申请中涉及的几个术语做简单介绍。
第五代移动通信技术(5th-Generation,5G)新空口(new radio,NR)系统中的下行公共信道可以分为：同步信号和物理广播信道块(Synchronization Signal and PBCH block, SSB)、寻呼信息(paging)和系统信息块(system information block,SIB)。SIB可以包括剩余最小系统信息(remaining minimum system information,RMSI)与其他系统信息(other system information,OSI)。
1、SSB
NR中，主同步信号(primary synchronization signal,PSS)/辅同步信号(secondary synchronization signal,SSS)和PBCH组合一起，时域上占用4个连续的符号，频域上占用20RB，形成SSB。同一个SSB采用相同的波束发送方式。可以理解，在时域上，一个SSB例如可由4个OFDM符号组成，在频域上，一个SSB例如可由240个连续的子载波组成，即，20个连续的RB。
图5示出了PSS/SSS以及PBCH占用的时域资源的一示意图。如图所示，相对于LTE系统中，同步序列PSS、SSS和PBCH在时频资源上的位置较为离散不同，NR重新设计了PSS、SSS和PBCH时频资源位置，使得它们更为紧凑，形成一体，称之为SSB。在时域上占据4个OFDM符号，频域占240个子载波。这种紧凑的结构，使得一经检测到同步序列之后，就可以进行解广播，加快了终端接入的速度，降低了系统的网络时延。
图6示出了PSS/SSS以及PBCH的发送机制的一示意图。如图所示，假设一个PBCH周期(PBCH period)为80ms，一个SS脉冲集发送窗(SS burst set Tx window)为5ms，即10个时隙(slots)。从图4可以看出，PSS、PBCH、SSS等所占的时域资源的位置。一个Slot中，包括了对应的剩余最小系统消息的控制资源集、SSB、对应的RMSI PDCCH以及自由填充时域资源。PSS、SSS和PBCH时域资源紧凑的连为一体，构成SSB。
2、小区(cell)
小区是高层从资源管理或移动性管理或服务单元的角度来描述的。每个网络设备的覆盖范围可以被划分为一个或多个小区，且该小区可以看作由一定频域资源组成。小区可以为网络设备的无线网络的覆盖范围内的区域。在本申请实施例中，不同的小区可以对应不同的网络设备。例如，小区#1中的网络设备和小区#2中的网络设备可以是不同的网络设备，如，基站。也就是说，小区#1和小区#2可以由不同的基站来管理，这种情况下，可以称为小区#1和小区#2共站，或者说，同站。小区#1中的网络设备和小区#2中的网络设备也可以是同一基站的不同的射频处理单元，例如，射频拉远单元(radio remote unit，RRU)，也就是说，小区#1和小区#2可以由同一基站管理，具有相同的基带处理单元和中频处理单元，但具有不同的射频处理单元。本申请对此不做特别限定。
在本申请实施例中，小区#1可以为第一频率范围内的小区，小区#2可以为第二频率范围内的小区。
3、双连接(dual-connectivity，DC)
双连接(dual-connectivity，DC)：终端设备可以同时与两个网络设备存在通信连接并可收发数据，可以称之为双连接。该两个网络设备(例如基站)之中，可以有一个网络设备负责与该终端设备交互无线资源控制消息，并负责和核心网控制平面实体交互，那么，该网络设备可以称之为主节点(master node，MN)，例如，主节点可以是MeNB或者MgNB，不限定于此；则另一个网络设备可以称之为辅节点(secondary node，SN)，例如，辅节点可以是SeNB或者SgNB，不限定于此。其中，主节点为控制面锚点，即终端设备与主节点建立RRC连接，且主节点与核心网之间建立控制面连接。在DC中，主节 点中的多个服务小区组成主小区组(master cell group，MCG)，包括一个主小区(primary cell，PCell)和可选的一个或多个辅小区(primary cell，PCell)。辅节点中的多个服务小区组成辅小区组(secondary cell group，SCG)，包括一个主辅小区(primary secondary cell，PSCell，或者，也可以称为特殊小区)和可选的一个或多个SCell。服务小区是指网络配置给终端设备进行上下行传输的小区。
在本申请实施例中，第一频率范围内的小区和第二频率范围内的小区，可以通过DC的方式为终端设备进行服务。
4、载波聚合(carrier aggregation，CA)
载波聚合(carrier aggregation，CA)：为了高效地利用零碎的频谱，系统支持不同载波单元之间的聚合。将2个或2个以上的载波聚合在一起以支持更大的传输带宽的技术可以称为载波聚合。
载波聚合技术中，终端设备可以配置多个载波单元(component carrier，CC，或者称，成员载波、组成载波、载波等)，每个CC可以对应于一个独立的小区。可以将一个CC等同于一个小区。例如，主小区对应主CC(或者称，主载波)，可以是为终端进行初始连接建立的小区，或进行RRC连接重建的小区，或是在切换(handover)过程中指定的主小区。辅小区对应辅CC(或者称，辅载波)，可以是在RRC重配置时添加的，用于提供额外的无线资源的小区。
对于处于连接态的终端设备来说，若未配置载波聚合，则该终端设备有一个服务小区；若配置了载波聚合，则该终端设备可以有多个服务小区(serving cell)，可以称为服务小区集合。例如，上文所述的主小区和辅小区组成了该终端设备的服务小区(serving cell)集合。换句话说，配置载波聚合的场景下，服务小区集合包括至少一个主小区和至少一个辅小区。或者说，配置了载波聚合的终端设备可与1个PCell和多个SCell进行数据传输。
在本申请实施例中，第一频率范围内的小区和第二频率范围内的小区，可以通过CA的方式为终端设备进行服务。
5、符号关断原理
在无有效数据发射时刻，关闭功放电源达到节能目的。在实际通信过程中，基站不是任何时候都处于流量最大状态，所以对于子帧中的符号，不是任何时刻都填满了有效信息。开启符号关断后，可以在在剩余的无有效信息传输的符号时间，关闭功放电源，达到节能目的。
图7为一种符号关断原理的示意图。如图所示，在高负荷工作模式下，当基站做下行传输的内容为参考符号和数据符号时，PA一直保持开启状态；在低负荷工作模式下，当基站做下行传输的内容为参考符号时，PA为开启状态，当为空闲符号时，PA为关闭状态。所以，基站节能的重要手段为预留更多的空闲时刻不做下行传输，可以获得更大的节能收益。
然后，在低载场景下，基站的SSB、SIB、Paging消息发送占据了大量的下行发送时隙，导致基站无法通过符号关断方式进行节能。下面具体说明。
在广播信道(broadcast channel,BCH)中传输的主系统模块(master information block，MIB)只包含非常有限的系统信息，而更多的系统信息是通过在下行共享信道(downlink shared channel,DL-SCH)中传输的SIB消息来告诉终端设备(user equipment,UE)的。对 于各类SIB而言，无线资源控制(radio resource control，RRC)消息中的信息就是其要告诉UE的所有信息。
SIB1和系统消息(system information,SI)都在物理下行共享信道(physical downlink shared channel,PDSCH)上传输，且SIB1和SI消息所占PDSCH的RB(频域上的位置)及其传输格式等是动态调度的，并由系统消息的无线网络临时标识符(system information-radio network temporary identity，SI-RNTI)加扰的物理下行控制信道(physical downlink control channel,PDCCH)来指示。MIB消息中的pdcch-ConfigSIB1字段就是用来指示SIB1的PDCCH时频资源。也就是说，UE需要先在pdcch-ConfigSIB1指示子帧上使用SI-RNTI加扰对PDCCH进行盲检，才能知道该子帧是否存在SI消息。表1为NR和长期演进(long term evolution,LTE)系统消息内容对比：
表1
Figure PCTCN2021101457-appb-000001
6、寻呼消息
当需要向处于空闲状态的UE发送下行数据时，移动管理节点(mobility management entity,MME)会向UE所注册的所有跟踪区(Tracking Area,TA)内的所有演进型基站(evolved node B，eNB)发送一条寻呼(paging)消息(MME发往eNB)，然后eNB会通过空口发送一条Paging消息(paging message)以寻呼UE。处于空闲状态的UE收到Paging消息后，可能会发起一个RRC连接建立过程以便接收呼叫。寻呼功能如下所述：
(1)向处于RRC_IDLE态的UE发送呼叫请求，由MME触发，后续UE将发起随 机接入，取得上行时间同步。
(2)通知所有UE，系统消息变更，由eNB触发。UE并不是一直在解析系统消息，而是在接收到系统消息变更信息时，再去重新解读系统消息；
(3)通知UE接收ETWS(地震海啸预警系统)通知(SIB10，SIB11)；
(4)通知UE接收CMAS(商用移动预警系统)通知(SIB12)；
Paging消息的内容是通过PDSCH资源位置发给UE的，而PDSCH资源是通过寻呼消息的无线网络临时标识符(paging-radio network temporary identity，P-RNTI)加扰PDCCH指示的。也就是UE要获得Paging消息，首先要周期性地醒来监视P-RNTI加扰的PDCCH信道，然后解析下行控制信息(downlink control information，DCI)，进一步得到PDSCH信道的时频位置。最后UE在对应的PDSCH信道的位置解析Paging的内容。
应理解，上述列举的各个消息的内容，仅是示例性说明，对此本申请实施例不作限定。
由上可知，网络设备发送的SSB、SIB、Paging消息发送占据了大量的下行发送时隙，导致网络设备无法通过符号关断方式进行节能。
有鉴于，本申请提供一种方案，通过多个同覆盖的不同频段小区协作配合，减少系统广播消息发送的数量，预留更多下行时隙用于符号关断节能。
图8为适用于本申请实施例提供的通信的方法的一种示意性框图。方法800可以包括如下步骤。
S801，第一频率范围内的小区确定进入节能状态；
S802，终端设备接入第二频率范围内的小区；
S803，第二频率范围内的小区协助第一频率范围内的小区，使得终端设备接入。
基于本申请实施例，第一频率范围内的小区可以进入节能状态，当该小区接入终端设备或者说为终端设备提供服务时，可以基于第二频率范围内的小区的协助，使得终端设备接入该第一频率范围内的小区。因此，不仅可以实现节能，还可以保证通信性能，提高用户体验。
下文实施例，为区分且不失一般性，用小区A表示第一频率范围内的小区，小区B表示第二频率范围内的小区。应理解，下文中的小区A可以替换为小区A所属的网络设备，小区B可以替换为小区B所属的网络设备。
一示例，第一频率范围内的小区可以表示容量层的小区，即小区A表示容量层的小区；第二频率范围内的小区可以表示覆盖层的小区，即小区B表示覆盖层的小区。
当前基站组网结构是一个多频段组网，组网方式可以为LTE和NR同覆盖组网或者新空口-时分双工(new radio-time division duplexing,NR-TDD)与新空口-频分双工(new radio-Frequency division Duplex,NR-FDD)同覆盖组网。通常情况下，有多频段/多频点载波同覆盖组网时，设定一个或者多个频段(一般是低频)为容量层，其余频段为覆盖层。或者也可以理解，小区A可以表示低频段中的小区，小区B为其余频段的小区。
又一示例，小区A为gNB TDD中的小区、小区B为gNB FDD中的小区。
又一示例，小区A为gNB SA/NSA中的小区、小区B为eNB中的小区。
应理解，小区A和小区B还可能有其他形式，此处不做限定。
可选地，小区A进入节能状态后，停止发送RMSI/OSI/Paging消息；和/或，小区A进入节能状态后，只发送SSB消息。
在NR的下行公共信道中，系统消息的用途如表2所示：
表2
消息 驻留 初始接入 切换 连接态
SSB √ √ √ √
RMSI √ √   系统消息更新
OSI   √   系统消息更新
Paging √     只发PDCCH
如表2所示，SSB具有驻留、初始接入、切换和连接态的功能，RMSI具有驻留、初始接入以及在连接态中系统消息更新的功能，OSI具有初始接入连接态中系统消息更新的功能，Paging具有驻留和连接态中只发PDCCH的功能。当把驻留和初始接入功能从小区A中剥离，可以减少RMSI/OSI/Paging的发送机会，甚至不用发送上述消息。
因此通过本申请实施例，可以减少系统广播消息发送的数量，预留更多下行时隙用于符号关断节能。
此外，驻留和初始接入功能可以由小区B(如覆盖层小区)负载，终端设备接入到小区B后，可以通过小区B的协助接入到小区A。应理解，本申请实施例中多次提及协助，协助即表示进入节能状态的小区A如果要接入终端设备时，可以通过其他小区(即小区B，如覆盖层的小区)的协助，使得终端设备接入至该小区A。
可选地，在以下任一情况下，小区A可能会进入节能状态：小区A所属的网络设备(如基站)的负载小于预设的第一门限、接入小区A或者小区A所属的网络设备(如基站)的用户数量小于预设的第二门限。
其中，预设的第一门限和第二门限，可以是预先规定的，如协议定义的，也可以是网络设备配置的；或者，也可以是根据历史通信情况确定的经验值。
下面结合图9和图10，介绍适用于本申请实施例的两个可能的流程。
图9为适用于本申请实施例提供的通信的方法的一种示意性流程图。方法900可以包括如下步骤。
S901、小区A进入节能状态。
一示例，小区A表示容量层的小区，小区B表示覆盖层的小区。又一示例，小区A为gNB TDD中的小区、小区B为gNB FDD中的小区。
关于小区A和小区B的描述，可以参考方法800中的描述，此次不再赘述。
示例地，在以下任一情况下，小区A可能会进入节能状态：小区A所属的网络设备(如基站)的负载小于预设的第一门限、接入小区A或者小区A所属的网络设备(如基站)的用户数量小于预设的第二门限。
其中，预设的第一门限和第二门限，可以是预先规定的，如协议定义的，也可以是网络设备配置的；或者，也可以是根据历史通信情况确定的经验值。
可选地，小区A进入节能状态后，停止发送RMSI/OSI/Paging消息；和/或，小区A进入节能状态后，只发送SSB消息。当把驻留和初始接入功能从小区A中剥离，可以减 少RMSI/OSI/Paging的发送机会，甚至不用发送上述消息。
因此通过本申请实施例，可以减少系统广播消息发送的数量，预留更多下行时隙用于符号关断节能。
其中，驻留和初始接入功能可以由小区B(如覆盖层小区)负载，终端设备接入到小区B后，可以通过小区B的协助接入到小区A。
S902、终端设备进行小区选择。
示例地，终端设备在空闲状态下，对小区进行接入选择。小区A处于节能状态，故终端设备读取小区A所在网络设备的SSB消息后发现该小区A无法驻留。
S903、终端设备接入至小区B。
如前所述，小区A进入节能状态，如果终端设备想要接入小区A，则终端设备可以通过小区B的协助接入到小区A。
S904、小区B向终端设备发送异频测量指示信息，相应地，终端设备接收该异频测量指示信息。

应理解，上述仅是示例性说明，对此不作限定。例如，小区B也可以根据终端设备待传输的数据量的大小确定是否要向终端设备发送切换信息。例如，当终端设备的数据量大小大于预设阈值时小区B可以向终端设备发送切换指示，如异频切换或者添加辅载波。
由上可知，在本申请实施例中，终端设备如果想要接入小区A，则可以通过该终端设备的服务小区(即小区B)的协助，如接收小区B的切换指示，进而根据小区B的切换指示接入至小区A。
S907、终端设备切换至小区A。
例如，终端设备可以通过激活辅载波的方式，切换至小区A。也就是说，小区A和小区B可以均为终端设备提供服务。
S908、小区A退出节能状态。
小区A接收终端设备后，可以退出节能状态。或者小区A也可以根据实际通信情况，确定是否要退出节能状态。例如，在以下任一情况下，小区A可能会退出节能状态：小区A所属的网络设备(如基站)的负载大于预设的第三门限、接入小区A或者小区A所属的网络设备(如基站)的用户数量大于预设的第四门限。
其中，预设的第三门限和第四门限，可以是预先规定的，如协议定义的，也可以是网络设备配置的；或者，也可以是根据历史通信情况确定的经验值。
可选地，小区A退出节能状态后，恢复发送RMSI/OSI/Paging消息，终端设备可以接入该小区。
在低载场景下，小区A的SSB，SIB，Paging消息发送占据了大量的下行发送时隙，导致基站无法通过符号关断方式进行节能。通过方法900的实施，可以关闭小区A的SSB， SIB，Paging消息发送，运用符号关断原理，在小区B的协同下，能够达到协同节能的效果。
图10为适用于本申请实施例提供的通信的方法的一种示意性流程图。方法1000包括如下步骤。

S1006、小区B向终端设备发送切换信息。
小区B可以根据终端设备上报的异系统测量结果，确定终端设备是否要切换至小区A。
在小区B根据终端设备上报的异系统测量结果确定终端设备可以切换至小区A时，小区B可以向终端设备发送切换指示，如异系统切换或者添加辅站。
应理解，上述仅是示例性说明，对此不作限定。例如，小区B也可以根据终端设备待传输的数据量的大小确定是否要向终端设备发送切换信息。例如，当终端设备的数据量大小大于预设阈值时小区B可以向终端设备发送切换指示，如异系统切换或者添加辅站。
由上可知，在本申请实施例中，终端设备如果想要接入小区A，则可以通过该终端设备的服务小区(即小区B)的协助，如接收小区B的切换指示，进而根据小区B的切换指示接入至小区A。
S1007、终端设备切换至小区A。

S1008、小区A退出节能状态。
小区A接收终端设备后，可以退出节能状态。或者小区A也可以根据实际通信情况，确定是否要退出节能状态。例如，在以下任一情况下，小区A可能会退出节能状态：小区A所属的网络设备(如基站)的负载大于预设的第七门限、接入小区A或者小区A所属的网络设备(如基站)的用户数量大于预设的第八门限。
其中，预设的第七门限和第八门限，可以是预先规定的，如协议定义的，也可以是网络设备配置的；或者，也可以是根据历史通信情况确定的经验值。
可选地，小区A退出节能状态后，恢复发送RMSI/OSI/Paging消息，终端设备可以接入该小区。
在低载场景下，小区A的SSB，SIB，Paging消息发送占据了大量的下行发送时隙，导致无法基站无法通过符号关断方式进行节能。通过方法1000的实施，可以关闭小区A的SSB，SIB，Paging消息发送，运用符号关断原理，在小区B的协同下，能够达到协同节能的效果。
