首先，对本申请实施例涉及的相关技术背景进行介绍：
对网络场景进行介绍：通信系统场景包括地面通信网络(Terrestrial Network，TN)和非地面通信网络(Non Terrestrial Network，NTN)。其中，NTN一般采用卫星通信的方式向地面用户提供通信服务。NTN系统目前包括新空口NTN(NewRadio-NTN，NR-NTN)和物联网NTN(Internet of Things-NTN，IoT-NTN)系统。示例性的，图1为本申请实施例提供的一种通信系统的架构示意图。如图1所示，通信系统100可以包括网络设备110，网络设备110可以是与终端120(或称为通信终端、终端设备)通信的设备。网络设备110可以为特定的地理区域提供通信覆盖，并且可以与位于该覆盖区域内的终端设备进行通信。网络设备110可以通过一个或多个小区向终端120提供无线通信服务，比如同时通过多个小区向终端120提供服务。当网络设备110通过多个小区向终端120提供服务时，该多个小区可以以载波聚合(Carrier Aggregation，CA)或双连接(Dual Connectivity，DC)的方式进行网络部署。相应地，终端120可以通过该多个小区中的部分(例如一个)或全部小区使用网络设备110提供的服务。在CA部署的网络场景下，该多个小区中的一个小区为主小区(Primary Cell，PCell)，其他小区为辅小区(Secondary cell，SCell)。在DC部署的网络场景下，该多个小区被分为两个小区组，即主小区组(Master Cell Group，MCG)和辅小区组(Secondary Cell Group，SCG)，其中MCG中的一个小区为主小区(PCell)，其他小区为辅小区(SCell)，SCG中的一个小区为主小区(Primary SCG Cell，PSCell)，其他小区为辅小区(SCell)。载波聚合技术或双连接技术能够提高终端120的吞吐量。在终端120不支持CA或DC的情况下，或者终端120支持CA或DC但未启用CA或DC的情况下，终端120可以仅使用一个小区作为主小区或服务小区。图1示例性地示出了一个网络设备和两个终端，在本申请一些实施例中，该通信系统100可以包括多个网络设备并且每个网络设备的覆盖范围内可以包括其它数量的终端，本申请实施例对此不做限定。该网络设备可以是基站。示例性的，图2为本申请实施例提供的另一种通信系统的架构示意图。请参见图2，包括终端1101和卫星1102，终端1101和卫星1102之间可以进行无线通信。终端1101和卫星1102之间所形成的网络还可以称为NTN。在图2所示的通信系统的架构中，卫星1102可以具有基站的功能，终端1101和卫星1102之间可以直接通信。在系统架构下，可以将卫星1102称为网络设备。在本申请一些实施例中，通信系统中可以包括多个网络设备1102，并且每个网络设备1102的覆盖范围内可以包括其它数量的终端，本申请实施例对此不做限定。示例性的，图3为本申请实施例提供的另一种通信系统的架构示意图。请参见图3，包括终端1201、卫星1202和基站1203，终端1201和卫星1202之间可以进行无线通信，卫星1202与基站1203之间可以通信。终端1201、卫星1202和基站1203之间所形成的网络还可以称为NTN。在图3所示的通信系统的架构中，卫星1202可以不具有基站的功能，终端1201和基站1203之间的通信需要通过卫星1202的中转。在该种系统架构下，可以将基站1203称为网络设备。在本申请一些实施例中，通信系统中可以包括多个网络设备1203，并且每个网络设备1203的覆盖范围内可以包括其它数量的终端，本申请实施例对此不做限定。
对网络节能进行介绍：网络节能(Network energy saving)对环境可持续性、减少对环境的影响(减少温室气体排放)、以及节省运营成本有重大意义。随着第5代(The 5 thgeneration，5G)移动通信网络在各个工业和地理区域的逐渐普及，需要支持非常高的数据传输速率来处理更高级的服务和应用，网络部署变得更密、使用更多天线、更大带宽和更多的频带。考虑到5G对环境的影响，需要开发受控的、新的解决 方案来增强网络节能。大多数的能源消耗来自于无线接入网络。更具体地，来自于激活天线单元(Active Antenna Unit，AAU)，其中，数据中心和光纤传输所占份额较小。一次无线接入的功率消耗可以被分为两部分：动态部分仅包括当数据正在进行发送或接收时的功率消耗；静态部分包括在所有时间情况下，为了维护无线接入设备的必要运营的功率消耗，包括没有进行发送或接收数据时的功率消耗。
因此，基于上述目的，需要研究和开发网络设备侧的网络能源消耗模型、关键绩效指标(Key Performance Indicator，KPI)、评估方法等，来确定和研究目标部署场景中的网络节能技术。其中，已经定义的终端侧的功率消耗模型可以作为参考。该研究应集中在如何实现更有效的动态运营和/或半静态运营，以及考虑应用于时域、频域、空域和功率域的一种或多种网络节能技术，联合潜在的终端反馈支持，潜在的终端辅助信息，以及网络接口之间的信息交换或协调等技术，以实现更细粒度的数据发送和/或接收自适应。值得注意的是，该研究不仅评估潜在的网络节能增益，而且也需要通过观察KPI，例如频谱效率、能力、用户感知吞吐量(User Perceived Throughput，UPT)、时延、终端功率消耗(UE power consumption)、复杂度、切换性能、掉话率(Call Drop Rate，CDR)、初始接入性能、服务等级协议(Service Level Agreement，SLA)安全相关的KPI等等，来评估和平衡对网络和用户性能的影响。该研究应避免对上述KPI产生较大的影响。
相关技术中的一种网络节能技术方法是，当网络处于空闲态的时候，增大同步信号块(Synchronization Signal and PBCH Block，SSB)和系统信息块(System Information Block，SIB)1的传输周期。然而，这种方法会增加终端设备初始接入的时延，因此，对于一个终端，可能会导致其在一个较长的SSB传输周期内不能正确识别该小区，从而无法接入网络。对于一些场景来说，当终端已经能够通过第一载波接收SSB和SIB1时，对于第二载波上传输的公共信号可以被简化，和/或，第二载波上传输的公共信号可以通过该第一载波上发送的信号来辅助接收。如图4所示，第一载波上传输的SSB占用4个符号，且第一载波上的SIB1中携带有第二载波的系统信息的调度信息。此时，第二载波(即其他载波)上传输的公共信号(图中的简单参考信号)只占用2个符号，和第一载波上的SSB占用的4个符号相比，第二载波上的公共信号占用的符号数较少，同时该公共信号也可以减少对终端的同步精度性能和接入时延的影响。但相关技术中的技术方案有如下缺点：需要重新设计第二载波上传输的公共信号，由于新的公共信号占用的符号数较少，除了需要评估该新的公共信号对网络节能带来的增益，以及评估该新的公共信号对终端性能的影响外，还需要考虑额外的终端实现复杂度。因此，本申请主要在不引入新的公共信号设计的情况下，考虑如何进行网络节能。
应理解，在本申请的一些实施例中，小区和载波可以等同。例如，“第一小区”可以替换为“第一载波”，“第二小区”可以替换为“第二载波”，等等。
应理解，在本申请的一些实施例中，“5G NR系统”也可以称为5G系统或者新空口(NewRadio，NR)系统。本申请的一些实施例中描述的技术方案可以适用于5G NR系统，也可以适用于5G NR系统后续的演进系统，还可以适用于6G以及后续的演进系统。
本申请的一个示例性实施例提供了一种主小区配置或重配置方法，能够当网络设备部署了两个或两个以上的小区时，如果网络设备中的业务负载较低，或者，网络设备在当前时间段服务的终端数较少，网络设备可以将其服务的终端集中到该两个或两个以上的小区中的某个小区或部分小区例如第二小区上，而对于终端被转移的第一小区，网络设备可以将第一小区关掉或仅在第一小区上传输基本的公共信号来维护终端的初始接入、寻呼等功能，从而达到节省网络设备的能量消耗的目的。在一个示例中，对于设置在某个旅游景点的网络设备而言，由于该旅游景点的营业时间为8:00到19:00，在非营业时间中该网络设备服务的终端数量大大减少，网络设备可以在非营业时间将其服务的终端集中到第二小区上，并仅在第一小区上传输基本的公共信号或关掉第一小区，从而节省非营业时间网络的能量消耗。
从终端的角度，当终端通过第一小区接入网络时，第一小区为终端的主小区。如果网络部署中包括多个小区，那么网络设备可以为该终端配置第二小区为该终端的辅小区。进一步地，如果网络设备确定对第一小区采用节能模式(例如将第一小区关掉或仅在第一小区上传输基本的公共信号等)，那么网络设备可以将终端的主小区从第一小区重配置为第二小区。
网络设备将终端的主小区从第一小区配置或重配置为第二小区，或者，终端根据网络设备的指示将主小区从第一小区配置或重配置为第二小区。在不同的时间段，网络设备可以将终端的主小区从第二小区重配置为第一小区，或者，终端根据网络设备的指示将主小区从第二小区重配置为第一小区。
