具体实施方式
为使本申请实施例的目的、技术方案和优点更加清楚，下面将结合附图对本申请实施方式作进一步地详细描述。
在对本申请实施例进行详细的解释说明之前，先对本申请实施例涉及的应用场景进行介绍。
目前，业界正在对未来通信技术进行积极的研究。相较于5G，未来通信技术的应用场景更为广泛且需求更加复杂，这将要求未来通信系统中的网络设备或终端具有更大的带宽、更快的处理速度和更多的天线等特性。而这些特性将会导致网络设备和/或终端的功耗比较大。对于网络设备而言，功耗大将会增加运营成本；对于终端而言，在终端的体积、面积、电池容量等受限增长的情况下，功耗大将会带来散热等诸多问题，严重影响用户体验。由此可见，网络设备和/或终端的功耗问题将成为未来通信技术面临的一大挑战。基于此，本申请实施例提供了一种通信方法，可以应用于未来通信系统中，当然也可以应用于5G、LTE等通信系统中。在该方法中，确定第一信息，该第一信息用于指示第一能量需求，且第一能量需求与第一配置关联。在此基础上，基于与该第一能量需求关联的第一配置来进行通信。由此可见，本申请实施例能够基于能量需求来配置通信装置进行通信，以此实现对通信装置的功耗的控制。
接下来对本申请实施例涉及的实施架构进行介绍。
图1是本申请实施例提供的通信方法所应用的通信系统的示意图。如图1所示，该通信系统10包括无线接入网(radio access network，RAN)100。其中，RAN100包括至少一个RAN节点(如图1中的110a和110b，统称为110)，还可以包括至少一个终端(如图1中的120a-120j，统称为120)。RAN100还可以包括其它RAN节点，例如，无线中继设备和/或无线回传设备(图1中未示出)。终端120通过无线的方式与RAN节点110相连。终端和终端之间以及RAN节点和RAN节点之间可以通过有线或无线的方式相互连接。通信系统10还可以包括核心网200。RAN节点110通过无线或有线方式与核心网200连接。核心网200中的网元与RAN100中的RAN节点110可以是独立的不同的物理设备，也可以是集成了核心网网元的逻辑功能与RAN节点的逻辑功能的同一个物理设备。通信系统10还可以包括外部的数据网络(data network，DN)300，例如，该外部的数据网络300可以为互联网。
RAN100可以是第三代合作伙伴计划(3rd generation partnership project，3GPP)中定义的演进的通用陆地无线接入(evolved universal terrestrial radio access，E-UTRA)系统、新无线(new radio，NR)系统以及未来的无线接入系统。RAN100还可以包括上述两种或两种以上不同的无线接入系统。RAN100还可以是开放式RAN(open RAN，O-RAN)。
RAN节点110，也称为无线接入网设备、RAN实体或接入节点，用以帮助终端120通过无线方式接入到通信系统中。
在一种应用场景中，RAN节点110可以是基站(base station)、演进型节点(evolved NodeB，eNodeB)、发送接收点(transmission reception point，TRP)、5G移动通信系统中的下一代节点(next generation NodeB，gNB)、未来移动通信系统中的节点或基站。RAN节点110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。

在本申请实施例中，能量需求可以是指与能量相关的要求或者是所需要满足的能量条件。第一信息可以是能够反映出第一能量需求的相关信息。
在一些实施例中，第一信息可以包括第一能量需求，该第一能量需求包括一个或多个能量指标。其中，能量指标可以是指能够评价能量使用情况的指标，例如，能量指标可以包括能耗(energy consumption)、能效(energy efficiency)、功耗(power consumption)、功效(power efficiency)和能量性能(energy performance)中的一个或多个。其中，能耗可以是指一段时间内所消耗的能源总量。能效可以是指一段时间内消耗的用于服务的有用能源量与该段时间内所消耗的能源总量之间的比值。功耗可以是指单位时间内的能耗。功效可以是指设备的输出功率与输入功率之间的比值。能量性能可以是指与能效、能源使用和能耗有关的其他可测量的指标。

具体的，该指标参考值可以为一个具体的指标数值。例如，第一信息可以包括能耗参考值，能效参考值等。可选地，该指标参考值也可以为一个指标等级值，该指标等级值可以用于指示一定的指标数值范围。例如，第一信息可以包括能耗等级值、能效等级值、功耗等级值、功效等级值等。其中，对于能效等级值和功效等级值，等级值越小，可以表示相应的指标数值越高，等级值越大，可以表示相应的指标数值越低。对于能耗等级值和功耗等级值，等级值越小，可以表示相应的指标数值越低，等级值越大，可以表示相应的指标数值越大。
在另一些实施例中，第一信息可以包括第一能量标识，该第一能量标识用于标识第一能量需求。具体的，可以通过协议预定义能量标识与能量需求之间的对应关系，其中，能量标识可以为一个标量，不同的能量标识对应不同的能量需求。在此基础上，第一能量标识可以为该对应关系中的一个能量标识。例如，上述的对应关系中的能量标识的取值范围为0至7，每个能量标识对应一种能量需求，第一能量标识可以为0至7中的一个。
在本申请实施例中，RAN节点可以通过以下三种方式来确定第一信息。
在第一种实现方式中，RAN节点可以接收来自核心网网元的第一QoS信息，在这种情况下，第一信息可以通过该第一QoS信息来指示。
其中，提供第一QoS信息的核心网网元可以为5G核心网中的网元，例如，SMF网元。或者，该核心网网元也可以为4G核心网的网元，例如，PCRF网元，或者，该核心网网元也可以为未来通信系统中的核心网的网元。并且，该第一QoS信息可以与一个或多个TRP关联，其中，第一QoS信息所关联的TRP中包括执行本步骤的RAN节点。
另外，该第一QoS信息可以是至少一个业务流对应的QoS信息，也即是，针对至少一个业务流设置的，用于保障该至少一个业务流的服务质量的信息，其中，该至少一个业务流可以包括第一业务流。在这种情况下，通过该第一QoS信息所指示的第一信息是指针对该至少一个业务流所设置的能量需求信息，用于指示传输该至少一个业务流的能量需求。在此基础上，该第一信息可以是RAN侧能量需求信息，用于指示RAN传输该至少一个业务流的能量需求，或者是，该第一信息可以是终端侧能量需求信息，用于指示终端传输该至少一个业务流的能量需求，或者是，该第一信息可以是核心网侧能量需求信息，用于指示核心网传输该至少一个业务流的能量需求，或者是，该第一信息也可以是系统能量需求信息，用于指示终端、RAN和核心网在传输该至少一个业务流的过程中总体的能量需求。

在一些实施例中，该第一QoS信息可以包括第一信息。
需要说明的是，对应有相同QoS信息的业务流可以称为一个QoS流，基于此，在本申请实施例中，对应第一QoS信息的至少一个业务流可以称为第一QoS流，相应的，第一信息为该第一QoS流对应的能量需求信息。
可选地，该第一QoS信息还可以包括第一QoS指示信息。其中，第一QoS指示信息用于指示第一QoS信息所指示的第一QoS流的QoS特征参数。例如，第一QoS指示信息可以为QCI或5QI。
需要说明的是，QCI或5QI为一个标量，可以用于标识一组QoS特征参数，每组QoS特征参数可以包括资源类型、优先级、包延迟预算(packet delay budget)和包错误丢失率(packet error loss rate)。
资源类型可以为保障比特速率(guaranteed bit rate，GBR)类型或non-GBR类型。GBR类型表示QoS流对应的承载所要求的比特速率能够得到保障。也即，即使在网络资源紧张的情况下，QoS流对应的承载所要求的比特速率也能够保持。non-GBR类型表示QoS流对应的承载的比特速率无法得到保障，例如，在网络资源紧张的情况下，QoS流对应的承载的比特速率可能会降低。可选地，在QoS指示信息为5QI的情况下，资源类型还可能为严格时延(delay critical)GBR类型，delay critical GBR表示QoS流对应的承载所要求的比特速率能够得到保障且具有更高的时延要求。优先级是指QoS流的转发优先级。优先级的值越小，表示QoS流的转发优先级越高，优先级的值越大，表示QoS流的转发优先级越低。包延迟预算是指QoS流的时延要求。包错误丢失率是指QoS流的丢包率或误包率要求。
可选地，第一QoS信息还可以包括分配和保留优先级(allocation and retention priority，ARP)，用于表示RAN接受第一QoS流对应的资源请求的优先级。其中，ARP的数值越小，表示该第一QoS流对应的资源请求被RAN接受的优先级越高。相反，ARP的数值越大，表示该第一QoS流对应的资源请求被RAN接受的优先级越低。

符号数可以是指设备传输的符号(symbol)的数量，符号数越少，设备的功耗或能耗可能越低。

部分带宽可以是指为终端动态配置的一部分带宽，是整个带宽的子集。通过为终端动态配置部分带宽，可以使得终端不必在整个带宽上工作，而是根据业务情况来动态调整终端在一部分带宽上工作，这样，可以降低终端的功耗或能耗。
载波也可以称为小区，为终端配置的载波可以是指为终端配置的服务小区，服务小区可以包括主小区和一个或多个辅小区，其中，服务小区中包括的小区数量越多，则终端的功耗或能耗可能越大。

例如，以参数集为MCS为例，能量需求与配置集合之间的对应关系可以包括能量需求与MCS之间的对应关系。其中，MCS可以通过MCS索引来标识，MCS包括调制阶数、目标码率和频谱效率。基于此，RAN节点可以从能量需求与MCS之间的对应关系中确定第一能量需求对应的一个或多个MCS，并从该一个或多个MCS中确定第一MCS。其中，第一配置包括第一MCS。
需要说明的是，在能量需求与MCS之间的对应关系中，每种MCS对应的能量需求可以相同或不同，其中，能量需求不同可以是指能量需求所包括的能量指标不同，或者，也可以是指能量需求所包括的能量指标相同但是能量指标的指标参考值不同。
例如，表3示出了一种能量需求与MCS之间的对应关系表。如表3中所示，每个MCS索引用于标识一种MCS，每种MCS包括调制阶数、目标码率和频谱效率。每种MCS对应一个能量需求，且对应的能量需求包括能效值和能耗值。其中，每种MCS对应的能效值可能相同或不同，对应的能耗值也可能相同或不同。例如，假设第一能量需求中的能效参考值为5比特/焦耳(bit/J)，能耗参考值为100毫瓦(mw)，则从表3中可以确定出该第一能量需求对应的是MCS索引为0的MCS，此时，该MCS索引为0的MCS即为第一MCS。再例如，假设第一能量需求包括能效这一能量指标，但是不包括该指标的参考值，则RAN节点可以从表3中确定最小的能效值，将最小的能效值对应的MCS作为第一MCS。
表3能量需求与MCS之间的对应关系表
需要说明的是，上述表3中各种MCS对应的能量需求所包括的能效值和能耗值仅是一种示例，并不构成对本申请实施例的限定。在一些可能的实现方式中，能量需求与MCS之间的对应关系表中MCS对应的也可以是能量指标值范围，例如，能效值范围和能耗值范围。基于此，RAN节点可以从该对应关系表中查找第一能量需求中的能量指标的指标参考值所处的值范围，并将查找到的值范围所对应的MCS确定为第一MCS。在另一些可能的实现方式中，如果MCS与能量需求之间的对应关系表中没有与第一能量需求中的能量指标的指标参考值相等的能量指标值，则RAN节点可以从该对应关系表中确定最接近该指标参考值的指标值，将该指标值对应的MCS作为第一MCS。例如，仍以上表3为例，当第一能量需求中的能效参考值为6bit/J，能耗参考值90mw，MCS索引为0的MCS对应的能效值和能耗值最接近上述两个参考值，则可以将MCS索引为0的MCS确定为第一MCS。
再例如，以参数集为包括一个或多个物理层参数的物理层参数集为例，能量需求与配置集合之间的对应关系可以为能量需求与物理层参数集之间的对应关系。基于此，RAN节点可以从能量需求与物理层参数集之间的对应关系中确定第一能量需求对应的一个或多个第一物理层参数集，其中，第一配置包括该一个或多个第一物理层参数集中的至少一个。或者，第一配置包括第一物理层参数集中的部分物理层参数。
需要说明的是，物理层参数可以包括时域参数、空域参数、频域参数和码域参数中的至少一种。

需要说明的是，下述表4中物理层参数集对应的能效值仅是一种示例，并不构成对本申请实施例的限定。在一些可能的实现方式中，能量需求与物理层参数集之间的对应关系表中物理层参数集对应的也可以是能量指标值范围，例如，能效值范围。基于此，RAN节点可以从该对应关系表中查找第一能量需求中的能量指标的指标参考值所处的值范围，并将查找到的值范围所对应的物理层参数集确定为第一物理层参数集。
表4能量需求与物理层参数集之间的对应关系表
在第二种示例中，每个配置集合包括一个或多个特性，相应的，能量需求与配置集合之间的对应关系可以包括能量需求与特性集之间的对应关系，其中，每个特性集包括一个或多个特性。基于此，RAN节点可以从能量需求与特性集之间的对应关系中确定第一能量需求对应的一个或多个第一特性集。其中，第一配置包括该一个或多个第一特性集中的至少一个。或者，第一配置包括第一特性集中的部分特性。
需要说明的是，不同的能量需求对应的特性集有可能相同，也有可能不同。其中，两个特性集不同可以是指两个特性集中包括的特性不同。
具体的，特性集包括的一个或多个特性可以包括以下至少一项：DRX、BWP自适应、跨时隙调度、稀疏MO配置、WUS、UL跳过-不监测、SSSG、节能辅助信息上报、RRC连接快速释放、SCell休眠、PEI、PDCCH跳过-不监测、移动性测量放松和统一节能模型。

BWP自适应是指为终端配置多种BWP，在此基础上，根据终端的业务数据量可以指示终端动态调整工作带宽；当数据量较少时，指示终端工作于较窄的带宽上以降低终端功耗；数据量大时，指示终端切换到较大的带宽上工作。
跨时隙调度是指PDCCH与其调度的PDSCH处于不同时隙，终端在接收到PDCCH后，无需缓存后续的下行信号，可直接关闭射频接收部分节省能耗，直到下一个时隙时再开启。
稀疏MO配置是指终端不必在每个时隙监测PDCCH，而是可以基于配置的监测周期，隔n个时隙监测一次PDCCH。

节能辅助信息上报可以是指终端通过向网络上报节能辅助信息，来使得网络基于该节能辅助信息为终端配置相应的资源，以实现节能。示例性的，节能辅助信息可以包括DRX配置的辅助信息、降低MIMO层数的辅助信息、降低辅载波的辅助信息等等。
RRC连接快速释放是指终端可以在没有数据的情况下，主动向网络上报信息，以请求进入非激活或空闲态。
SCell休眠是指在终端有待收发的数据时，处于激活态的SCell可以进入休眠态。其中，终端可以根据PCell上接收的下行控制信息(downlink control information，DCI)指示来确定SCell进入休眠态，在休眠态下，终端不接收SCell的PDCCH，只进行信道状态信息(channel state information，CSI)测量，在有数据传输时可快速将SCell从休眠态切换到激活态。
PEI主要用于RRC空闲态下。在寻呼时机之前终端可以通过接收PEI，判断下一个寻呼时机是否需要唤醒来接收寻呼。
PDCCH跳过-不监测是指：RAN节点可以通过DCI指示终端在该DCI后的持续n个时隙(简称skipped duration)上无需监测PDCCH，从而达到节能目的。

统一节能模型是指预定义的多种节能图样的集合，该多种节能图样可以实现上述节能特性的等效节能效果。进一步地，可通过信令指示不同的节能图样用于终端节能。
在第三种示例中，每个配置集合包括一种或多种物理层工作模式，相应的，能量需求与配置集合之间的对应关系可以包括能量需求与物理层工作模式之间的对应关系。其中，每种物理层工作模式可以对应一个物理层参数集，物理层参数集可以包括一个或多个物理层参数。基于此，在本申请实施例中，RAN节点可以从能量需求与物理层工作模式之间的对应关系中确定第一能量需求所对应的一个或多个第一物理层工作模式，其中，第一配置包括该一个或多个第一物理层工作模式中的至少一个。
需要说明的是，不同的能量需求对应的物理层工作模式有可能相同，也有可能不同。在一些示例中，物理层工作模式可以包括节能模式和普通模式，其中，相较于利用普通模式所对应的物理层参数集来配置的物理层，利用节能模式所对应的物理层参数集来配置的物理层在传输信号时更为节能。所谓的更为节能，可以是指能效或功效更高，或者是能耗或功耗更低。
例如，节能模式所对应的物理层参数集中，带宽为30MHz，MIMO层数为1，PDCCH MO间隔为50毫秒(ms)，载波调度方式为跨载波调度。普通模式所对应的物理层参数集中，带宽为100MHz，MIMO层数为4，PDCCH MO间隔为10ms，载波调度方式为跨载波调度。

表5能量需求与物理层工作模式之间的对应关系表
需要说明的是，上述表5中仅以物理层工作模式包括节能模式和普通模式为例进行示例性说明。在一些可能的情况中，物理层工作模式的划分方法还可以有其他的实现方式，例如，除了节能模式和普通模式，还可以包括其他模式。或者，对于节能模式，还可以按照节能程度大小，划分为多个不同节能程度的节能模式等等。
另外，上述三种示例仅是本申请实施例给出的能量需求与配置集合的对应关系的示例性实现方式，并不构成对本申请实施例的限定。例如，在一些可能的实现方式中，能量需求与配置集合的对应关系也可以包括能量需求与配置集合的集合标识之间的对应关系，其中，每个集合标识可以索引到一个配置集合。基于此，RAN节点可以从该对应关系中确定第一能量需求对应的一个或多个集合标识，并基于该一个或多个集合标识确定出第一能量需求对应的一个或多个第一配置集合，其中，第一配置可以包括一个或多个第一配置集合中的至少一个。
在一些可能的情况中，由前述介绍可知，第一配置是能够满足第一信息所指示的第一能量需求的配置。在此基础上，在上述介绍的基于能量需求与配置集合的对应关系确定第一能量需求关联的第一配置的各个示例中，如果第一信息是通过第一QoS信息指示的，则第一配置不仅仅是能够满足第一信息所指示的第一能量需求的配置，而且还可以是能够满足第一QoS信息中的其他参数条件的配置。也即，第一配置可以是第一QoS信息所关联的配置。
具体地，在第一信息通过第一QoS信息指示、且第一QoS信息还包括除第一信息之外的其他参数的情况下，RAN节点可以基于第一信息所指示的第一能量需求和第一QoS信息中包括的其他参数，来确定第一配置。
在一种示例中，RAN节点可以基于第一QoS信息中的其他参数确定候选配置集合，之后，基于第一能量需求和候选配置集合，确定第一配置。

具体地，对于QoS参数集所对应的各个配置集合，存在这些配置集合和能量需求的对应关系。基于此，在确定出至少一个候选配置集合之后，RAN节点可以基于该至少一个候选配置集合所对应的能量需求，确定满足第一能量需求的一个或多个第一配置集合。
其中，在第一能量需求包括能量指标但不包括指标参考值的情况下，以第一能量需求包括第一能量指标为例，RAN节点可以从该至少一个候选配置集合中确定对应有第一能量指标，且对应的第一能量指标的值满足预设条件的配置集合作为第一配置集合。其中，预设条件可以是第一能量指标的预设阈值，或者是第一能量指标的值最大或最小等。比如，第一能量指标为能效，则RAN节点可以从至少一个候选配置集合中选择对应的能效值最大的配置集合作为第一配置集合。
在第一能量需求包括能量指标的指标参考值的情况下，以第一能量需求包括第一能量指标的指标参考值为例，RAN节点可以从该至少一个候选配置集合中确定对应有第一能量指标，且对应的第一能量指标的值满足第一能量指标的指标参考值的配置集合作为第一配置集合。比如，第一能量指标包括能效参考值，则RAN节点可以从该至少一个候选配置集合中选择对应的能效值等于能效参考值的配置集合作为第一配置集合。可选地，如果不存在对应的能效值等于能效参考值的配置集合，则可以选择对应的能效值大于能效参考值的配置集合作为第一配置集合。可选地，如果不存在对应的能效值等于或大于能效参考值的配置集合，则可以选择对应的能效值最大的配置集合作为第一配置集合。或者，RAN节点也可以从该至少一个候选配置集合中选择对应的能效值范围包括该能效参考值的配置集合作为第一配置集合。
例如，图7是本申请实施例提供的一种基于能量需求以及其他的QoS参数确定第一配置的示意图。如图7所示，QoS参数集A中的GFBR为20兆比特率(Mbps)，包延迟预算为50ms，对应的配置集合可以包括两种物理层工作模式，分别为节能模式和普通模式；QoS参数集B中的GFBR为50Mbps，包延迟预算为100ms，对应的配置集合也可以包括两种物理层工作模式，分别为节能模式和普通模式；QoS参数集C中的GFBR为100Mbps，包延迟预算为50ms，对应的配置集合可以包括一种物理层工作模式，为普通模式；QoS参数集D中的GFBR为1.6Gbps，包延迟预算为10ms，对应的配置集合也可以包括一种物理层工作模式，为普通模式。假设第一QoS信息中的GFBR为50Mbps，第一QoS指示信息所指示的包延迟预算为50ms，基于图7中各个QoS参数集对应的配置集合可知，该第一QoS信息中的GFBR和指示的包延迟预算所对应的候选配置集合可以包括两种物理层工作模式，分别为节能模式和普通模式。在此基础上，如果第一能量需求包括能耗指标且不包括能耗指标的指标参考值，则基于该第一能量需求从这两种物理层工作模式中可以选择能耗更小的节能模式。此时，第一配置即为节能模式。如果第一能量需求包括能耗指标的指标参考值，且在普通模式下即能满足该指标参考值，则基于该第一能量需求可以从两种物理层工作模式中选择普通模式。如果在普通模式下无法满足该指标参考值，则基于该第一能量需求可以从两种物理层工作模式中选择节能模式。
可选地，在第一QoS信息包括第一QoS指示信息，且第一QoS指示信息指示的QoS特征参数包括第一信息的情况下，能量需求与配置集合之间的对应关系可以通过QoS指示信息与配置集合之间的对应关系来实现。基于此，RAN节点可以基于该对应关系确定第一QoS指示信息所对应的一个或多个配置集合，该配置集合即为满足第一能量需求的配置集合，第一配置包括该第一QoS指示信息所对应的一个或多个配置集合中的至少一个。或者，第一配置包括该第一QoS指示信息所对应的某个配置集合中的部分配置。
在另一种示例中，由前述介绍可知，第一QoS信息为至少一个业务流对应的QoS信息。对应有相同的QoS信息的业务流可以称为一个QoS流，QoS流可以通过一个流标识来指示，例如，流标识可以为QoS流标识符(QoS flow identifier，QFI)或QCI。相应的，QoS信息可以与自身所指示的QoS流的流标识关联。在这种情况下，能量需求与配置集合之间的对应关系可以通过流标识与配置集合之间的对应关系来实现。相应的，RAN节点可以获取第一QoS信息所关联的第一QoS流的流标识，之后，基于流标识与配置集合之间的对应关系，确定第一QoS流的流标识对应的一个或多个配置集合，该配置集合即为满足第一能量需求的配置集合，第一配置包括该第一QoS流的流标识对应的一个或多个配置集合中的至少一个。或者，第一配置包括该第一QoS流的流标识对应的某个配置集合中的部分配置。其中，第一QoS流包括对应有第一QoS信息的至少一个业务流。
需要说明的是，第一QoS流的流标识所对应的配置集合即为第一QoS流关联的配置集合，而由于第一QoS流包括对应有第一QoS信息的至少一个业务流，因此，第一配置实际上就是该至少一个业务流所关联的配置。
可选地，一个QoS流还可以关联一个DRB，该DRB用于传输该QoS流所包括的业务流。基于此，本申请实施例中能量需求与配置集合之间的对应关系可以通过流标识与DRB标识之间的第一对应关系，以及DRB标识与配置集合之间的第二对应关系来实现。相应的，RAN节点在获得第一QoS信息所关联的第一QoS流的流标识之后，可以基于第一对应关系，确定第一QoS流的流标识对应的第一DRB标识，之后，基于第二对应关系，确定第一DRB标识对应的一个或多个配置集合，其中，第一配置包括第一DRB标识对应的一个或多个配置集合中的至少一个，或者，第一配置包括第一DRB标识对应的某个配置集合中的部分配置。
例如，图8是本申请实施例示出的一种确定第一QoS信息所对应的第一配置的示意图。如图8所示，QFI1与DRB1关联，DRB1与配置集合1关联；QFI2与DRB2关联，DRB2与配置集合2关联；QFIk与DRBk关联，DRBk与配置集合k关联。假设第一QoS信息关联的QFI为QFI2，则基于QFI2确定出关联的DRB2，基于DRB2可以确定出对应的配置集合2，此时，第一配置可以为该配置集合2。
在另一些可能的情况中，如果上述的第一信息是第一SLA中包含的信息，由于第一SLA可以关联一个SLA流，所以，第一信息所指示的第一能量需求可以是该第一SLA所指示的SLA流所关联的能量需求，相应的，第一配置将是该第一SLA所指示的SLA流关联的配置。
在另一种可能的实现方式中，RAN节点可以基于第一能量需求确定无线资源配置，第一配置包括该无线资源配置。
由前述介绍可知，第一信息可以是针对对应有第一QoS信息的至少一个业务流配置的能量需求信息，该至少一个业务流可以称为第一QoS流，该第一QoS流可以关联第一DRB。基于此，第一信息所指示的第一能量需求即为第一DRB关联的能量需求。在这种情况下，RAN节点可以基于该第一能量需求为第一DRB分配第一无线资源，进而生成用于指示该第一无线资源的第一无线资源配置。
具体的，在一个示例中，RAN节点可以根据第一QoS信息中的QoS参数以及第一能量需求利用资源调度算法来为第一DRB分配第一无线资源。其中，该第一无线资源可以包括为第一DRB分配的时域资源和频域资源。并且，利用该第一无线资源通过该第一DRB来传输第一QoS流，能够满足第一QoS信息中的QoS参数以及第一能量需求。
例如，对于包括第一QoS信息所指示的业务在内的多个有下行数据传输请求的业务，RAN节点可以获取每个业务对应的QoS信息中的QoS参数以及能量需求来计算每个业务的优先级，之后，按照优先级从高到底的顺序依次为各个业务调度资源。
可选地，RAN节点在确定各个业务的优先级时，除了考虑QoS信息和能量需求，还可以根据调度内容、信道质量、终端或者是业务的历史速率、调度优先级的相关信息、数据包缓冲信息中的一种或多种来确定各个业务的优先级。其中，调度内容可以为数据或控制信息，数据包缓冲信息可以包括缓存大小、缓存时延等。
可选地，RAN节点也可以直接根据第一能量需求来为第一DRB分配第一无线资源。例如，对于包括第一QoS信息所指示的业务在内的多个有下行数据传输请求的业务，RAN节点可以直接按照各个业务对应的能效或功效从大到小或者是能耗或功耗从小到大的顺序来确定各个业务的优先级。
在另一个示例中，RAN节点也可以根据第一QoS信息中的QoS参数为第一DRB确定多个候选无线资源。之后，针对第一能量需求中包括的能量指标，确定每个候选无线资源对应的该能量指标的预估值，从该多个候选无线资源中确定出对应的该能量指标的预估值满足该第一能量需求的无线资源作为第一无线资源。
可选地，第一信息也可以是针对某个终端配置的能量需求信息，相应的，第一能量需求是某个终端传输业务数据的能量需求。在这种情况下，RAN节点可以基于该第一能量需求为对应的终端分配第二无线资源，进而生成用于指示第二无线资源的第一无线资源配置。
具体地，在一个示例中，RAN节点可以根据该第一能量需求所对应的终端的优先级、该终端所能达到的传输速率等参数以及该第一能量需求，利用资源调度算法来为该终端分配第二无线资源。
在另一个示例中，RAN节点也可以根据第一能量需求所对应的终端的优先级、该终端所能达到的传输速率等参数确定多个候选无线资源。之后，针对第一能量需求中包括的能量指标，确定每个候选无线资源对应的该能量指标的预估值，从该多个候选无线资源中确定出对应的该能量指标的预估值满足该第一能量需求的无线资源作为第二无线资源。

可选地，该配置信息可以用于指示第二配置。其中，该第二配置不超过第一配置。所谓的第二配置不超过第一配置可以是指第二配置的能量需求不超过第一配置。例如，当能量需求为能耗需求或功耗需求时，第二配置不超过第一配置可以是指第二配置所带来的能耗或功耗不超过第一配置所带来的能耗或功耗。再例如，当能量需求为能效需求或功效需求时，第二配置不超过第一配置可以是指第二配置所对应的能效或功效不低于第一配置对应的能效或功效。
具体的，第二配置可以包括第二参数集、第二特性集、第二物理层工作模式、第二无线资源配置中的至少一种，其中，该第二参数集可以基于一个或多个第一参数集确定得到，第二特性集可以基于一个或多个第一特性集确定得到，第二物理层工作模式可以基于一个或多个第一物理层工作模式确定得到，第二无线资源配置可以基于第一无线资源配置得到。在此基础上，该配置信息可以包括第二配置或用于指示第二配置的第二指示信息。
在一些实施例中，如果第一能量需求是针对对应有第一QoS信息的至少一个业务流配置的，则配置信息所指示的第一配置或第二配置是该至少一个业务流关联的配置。在此基础上，RAN节点可以向传输该至少一个业务流中的任一个业务流的终端发送该配置信息。例如，第一QoS信息对应的至少一个业务流包括第一业务流，RAN节点可以向传输第一业务流的终端发送配置信息。在这种情况下，该配置信息还可以用于指示该配置信息所指示的第一配置或第二配置所关联的至少一个业务流。
例如，对应有第一QoS信息的至少一个业务流可以称为第一QoS流，基于此，该配置信息中还可以包括第一QoS流的流标识，以此来指示该配置信息所指示的第一配置或第二配置为第一QoS流所关联的配置。
可选地，第一QoS流还可以关联第一DRB，在这种情况下，第一配置或第二配置即为与第一DRB关联的配置，基于此，该配置信息还可以用于指示该第一配置或第二配置为第一DRB关联的配置，例如，该配置信息还可以包括第一DRB的标识。
在另一些实施例中，如果第一能量需求是针对第一SLA所指示的第一SLA流配置的，则配置信息所指示的第一配置或第二配置即为第一SLA流关联的配置。在这种情况下，RAN节点可以向传输第一SLA流的终端发送用于指示第一配置或第二配置的配置信息。其中，传输第一SLA流的终端可能有一个，也可能有多个。可选地，配置信息中还可以包括用于指示第一SLA流的指示信息。

具体的，终端可以随机选择一个参数集，或者，也可以按照预设策略选择一个参数集。例如，在前述的第一信息不为终端侧能量需求信息的情况中，终端中还可以配置有第二信息，该第二信息为终端侧能量需求信息，用于指示第二能量需求。基于此，终端可以从多个参数集中选择能够满足第二能量需求的一个参数集作为目标参数集。
在确定出目标参数集之后，终端可以根据该目标参数集来发送和/或接收信息。
在第一个示例中，目标参数集包括第一MCS。终端的物理层可以基于该第一MCS对待发送的第一信号进行调制和编码，并发送调制和编码后的第一信号；和/或，基于第一MCS，对接收到的第一信号进行解调。
其中，如果配置信息中还包括第一QoS流的流标识，则终端的物理层可以利用该第一MCS对待发送的且属于第一QoS流的第一信号进行调制和编码，并发送调制和编码后的第一信号。和/或，终端的物理层可以在接收到属于第一QoS流的第一信号之后，基于该第一MCS对该第一信号进行解调。此时，该第一信号可以包括属于第一QoS流的任一个业务流的业务数据。
具体的，终端可以确定第一QoS流所关联的第一DRB，之后，终端可以通过该第一DRB对应的物理层实体，利用该第一MCS对由该第一DRB所承载的第一信号进行调制和编码，和/或，解调。
其中，如果该配置信息中包括第一QoS流关联的第一DRB的标识，则终端可以基于该第一DRB的标识，确定第一DRB。如果配置信息中不包括第一DRB的标识，则终端中可以配置有流标识与DRB标识之间的映射关系，基于此，终端可以基于该映射关系确定第一QoS流的流标识对应的DRB标识，该DRB标识所指示的DRB即为第一DRB。

需要说明的是，终端可以确定第一QoS流所关联的第一DRB。之后，终端中该第一DRB对应的物理层实体可以基于该第一物理层参数发送或接收由该第一DRB所承载的第一信号。其中，确定第一QoS流所关联的第一DRB的实现方式可以参考前述介绍，在此不再赘述。
可选地，第一配置或第二配置也可以包括无线资源配置。在这种情况下，终端可以利用第一配置或第二配置中的无线资源配置所指示的无线资源，接收和/或发送第一信号。
在一个示例中，如果该无线资源配置指示的是为第一QoS流分配的无线资源，则终端可以利用该无线资源接收和/或发送属于第一QoS流的第一信号。其中，该第一信号可以包括属于第一QoS流的任一个业务流的业务数据。
具体地，终端可以确定第一QoS流所关联的第一DRB，之后，利用该第一无线资源，在该第一DRB上接收或发送第一信号。
其中，确定第一QoS流所关联的第一DRB的实现方式可以参考前文介绍。
另外，第一无线资源可以包括时域资源和/或频域资源。基于此，终端可以利用该时域资源和/或频域资源，在第一DRB上接收或发送第一信号。
在另一个示例中，如果该无线资源配置指示的是为终端分配的无线资源，则终端可以利用该无线资源接收或发送第一信号。其中，该第一信号可以是任一个业务流的业务数据，或者，该第一信号也可以是控制信息。
在第二种情况中，配置信息包括第一指示信息或第二指示信息，终端可以基于第一指示信息确定第一配置或者是基于第二指示信息确定第二配置，进而根据该第一配置或第二配置发送和/或接收第一信号。接下来以配置信息包括第一指示信息为例进行详细说明，对于配置信息包括第二指示信息的实现方式可以参考包括第一指示信息时的实现方式。
在第一个示例中，第一指示信息可以包括一个或多个第一特性集的标识，基于此，终端可以基于该一个或多个第一特性集的标识确定出一个或多个第一特性集，之后，根据该一个或多个第一特性集确定出目标特性集，进而根据目标特性集中的特性来发送和/或接收第一信号。其中，确定目标特性集的实现方式可以参考确定目标参数集的实现方式，在此不再赘述。
另外，目标特性集中可以包括一个或多个特性，对于任一特性，终端可以确定对应的特性的相关参数，进而基于确定出的参数，发送和/或接收第一信号。
例如，目标特性集中包括DRX，则终端可以确定DRX的相关参数，例如，DRX周期内的激活时间段和休眠时间段等。之后，终端在DRX周期内的激活时间段内唤醒，监测PDCCH，并根据PDCCH的指示来发送和/或接收数据。在DRX周期内的休眠时间段内进入休眠状态，不再监测PDCCH，也不再收发数据。其中，第一信号可以包括PDCCH和/或收发的数据。

需要说明的是，上述实施例中主要介绍了RAN节点基于第一配置向终端发送配置信息，以此来使终端按照该配置信息收发信号的实现过程。在一些可能的情况中，第一配置可能还包含有RAN侧的配置，可以用于对RAN节点进行配置。基于此，RAN节点还可以基于第一配置对自身进行相关的配置，以此来与包括终端、核心网网元在内的其他通信装置进行通信。
在本申请实施例中，RAN节点可以确定第一信息，该第一信息用于指示第一能量需求，且该第一能量需求关联第一配置。在此基础上，基于该第一能量需求确定第一配置，并基于第一配置发送配置信息，以指示接收到该配置信息的终端基于配置信息所指示的配置来发送或接收第一信号。由此可见，本申请实施例能够基于能量需求来配置终端进行信号收发，以此实现对通信系统的功耗的控制。
另外，在本申请实施例中，第一信息可以通过第一QoS信息来指示。由于基于QoS信息所进行的QoS控制是通信系统为了保障业务的服务质量所提供的原生(native)功能，所以，通过QoS信息来指示能量需求信息，可以使得基于能量需求信息的节能控制也成为通信系统的原生功能，也即，使能通信系统原生节能。
基于上述实施例中介绍的通信方法，本申请实施例还提供了另一种通信方法的示例性流程，参见图10，该过程包括以下步骤：
S1001：终端向RAN节点发送配置请求，该配置请求用于请求第一信号或第一业务流关联的配置。相应的，RAN节点接收该配置请求。
在一些实施例中，终端可以确定第二信息，该第二信息用于指示第二能量需求，且第二能量需求关联第三配置。终端可以基于该第三配置向RAN节点发送配置请求。
其中，第二信息可以与第一信息相同，也可以不同。当第二信息与第一信息不同时，第二能量需求与第一能量需求不同。其中，第二能量需求与第一能量需求不同可以是指包括的能量指标不同。或者，在第二能量需求和第一能量需求均包括能量指标的指标参考值的情况下，对于相同的能量指标，指标参考值可以不同。其中，关于能量指标和能量指标的指标参考值的介绍可以参考前文中S601的介绍，在此不再赘述。
在本申请实施例中，终端也可以通过以下三种方式来确定第二信息。
在第一种实现方式中，终端可以接收来自核心网网元的第一QoS信息。第二信息可以通过该第一QoS信息来指示。其中，第一QoS信息指示第二信息的方式可以参考前述S601中介绍的第一QoS信息指示第一信息的方式。
需要说明的是，在第二信息和第一信息均通过第一QoS信息指示的情况下，第二信息和第一信息可以是不同种类的能量需求信息，例如，第二信息可以为终端侧能量需求信息，第一信息可以为RAN侧能量需求信息。或者，第二信息可以为终端侧能量需求信息，第一信息可以为系统级能量需求信息。
可选地，第二信息和第一信息也可以相同，此时，该第二信息和第一信息可以是终端侧能量需求信息、RAN侧能量需求信息、核心网侧能量需求信息或系统级能量需求信息。
在第二种实现方式中，终端可以获取自身对应的第一SLA，该第一SLA包括第二信息。
具体地，终端可以从AAA服务器或核心网网元中获取自身对应的第一SLA。其中，该核心网网元可以为AUSF网元，或者，也可以为未来通信系统中用于管理或存储SLA的网元。
需要说明的是，第二信息和第一信息可以是不同种类的能量需求信息，例如，第二信息可以为终端侧能量需求信息，第一信息可以为RAN侧能量需求信息。或者，第二信息可以为终端侧能量需求信息，第一信息可以为系统级能量需求信息。
可选地，第二信息与第一信息可以是相同的，此时，该第二信息和第一信息该可以是终端侧能量需求信息、RAN侧能量需求信息、核心网侧能量需求信息或系统级能量需求信息。
在第三种实现方式中，终端中可以静态配置有第二信息。在这种情况下，终端可以直接获取该第二信息。
其中，关于第二信息与第一信息的关系可以参考前述两种实现方式中的介绍，在此不再赘述。
终端在获取到第二信息之后，可以确定该第二信息关联的第三配置，之后，基于该第三配置向RAN节点发送配置请求。其中，该配置请求用于请求以该第三配置发送和/或接收第一信号。
其中，终端确定第二信息关联的第三配置的实现方式，可以参考前述介绍的RAN节点确定第一信息关联的第一配置的实现方式，在此不再赘述。
另外，配置请求可以包括第三配置或者是用于指示第三配置的第三指示信息。
例如，第三配置可以包括一个或多个第三参数集，相应的，配置请求可以包括一个或多个第三参数集或者是各个第三参数集的标识。再例如，第三配置包括一个或多个第三特性集，配置请求包括一个或多个第三特性集的标识。再例如，第三配置包括一个或多个第三物理层工作模式，配置请求包括一个或多个第三物理层工作模式的标识。
可选地，第三配置也可以包括期望的第三无线资源配置，相应的，配置请求可以包括该第三无线资源配置。
需要说明的是，在本申请实施例中，第二信息可以是针对该终端的各种业务数据配置的能量需求信息，相应的，该第三配置是针对该终端的各种业务数据的配置，在这种情况下，该配置请求用于请求针对该终端的各种业务数据的配置。
或者，第二信息可以是针对第一QoS信息所指示的第一QoS流配置的能量需求信息，则第三配置是针对第一QoS流的配置，在这种情况下，配置请求中还可以包括第一QoS流的流标识，以此来指示该配置请求是用于请求针对该第一QoS流的配置。可选地，该配置请求中还可以包括第一QoS流关联的第一DRB的标识。
在另一些实施例中，终端也可以不确定第二信息，而是直接发送配置请求，在这种情况下，配置请求也可以不包括第三配置或用于指示第三配置的第三指示信息。此时，该配置请求用于请求与终端的相关配置。
例如，该配置请求可以包括第一QoS流的流标识，可选地，还可以包括第一QoS流关联的第一DRB的标识，以此来指示该配置请求用于请求属于第一QoS流的各个业务流所关联的配置。
再例如，该配置请求可以包括终端标识，以此来指示该配置请求用于请求该终端的各种业务数据所关联的配置。
S1002：RAN节点基于第一信息和该配置请求，确定第一配置。
其中，RAN节点中的第一信息可以预先通过参考前述S601中的实现方式获得。在此基础上，在接收到配置请求之后，RAN节点可以基于该配置请求确定出第一信息。
如果配置请求包括第一QoS流的流标识，则RAN节点可以基于该第一QoS流的流标识确定第一QoS信息，进而基于该第一QoS信息来确定第一信息。
如果该配置请求不包括第一QoS流的流标识，则RAN节点可以基于该终端的相关信息来获取第一信息。例如，该终端的第一SLA中包括第一信息，且第一SLA中还可以包括该终端的相关信息。这样，RAN节点可以根据该终端的相关信息查找到第一SLA，进而从第一SLA中获取到第一信息。
在配置请求不包括第三配置或用于指示第三配置的第三指示信息的情况下，RAN节点在确定出第一信息之后，可以基于该第一信息确定第一能量需求，并基于第一能量需求确定第一配置。相关实现方式参考前述S602和S603。
在配置请求包括第三配置或第三指示信息的情况下，RAN节点还可以基于配置请求确定出第三配置。基于第一信息确定第一能量需求，之后，基于第一能量需求和第三配置，确定第一配置。
其中，RAN节点可以直接获取配置请求中携带的第三配置或者是根据配置请求中的第三指示信息确定第三配置，详细实现方式与前述实施例中S6032中终端基于配置信息确定第一配置的相关实现方式相似，在此不再赘述。另外，RAN节点确定第一信息所指示的第一能量需求的实现方式参考前述S601。
在确定出第三配置和第一能量需求之后，针对第一能量需求包括的能量指标，如果第三配置对应的该能量指标的值能够满足该第一能量需求，则RAN节点可以将该第三配置作为第一配置。此时，该第一配置为同时满足第一能量需求和第二能量需求的配置。
可选地，如果第三配置对应的该能量指标的值不满足该第一能量需求，则RAN节点可以参考前述实施例中S602介绍的方法，基于第一能量需求确定第一配置。
S1003：RAN节点基于第一配置向终端发送配置信息，该配置信息用于指示第一配置或第二配置。相应的，终端接收该配置信息。
该步骤的实现方式可以参考前述实施例中的S6031。
S1004：终端基于该配置信息，接收和/或发送第一信号。
该步骤的实现方式可以参考前述实施例中的S6032。
在本申请实施例中，终端可以基于自身获得的第二信息，主动向RAN节点请求自身期望的配置，RAN节点可以基于终端期望的配置来为终端下发配置信息，以此来使得终端能够在采用自身期望的配置传输信号的情况下实现功耗的控制。
上文中的各个实施例中主要介绍了RAN侧和终端侧如何基于能量需求进行信号传输，以实现功耗控制。在一些可能的实现方式中，核心网也可以基于能量需求来控制RAN和终端进行信号传输，以此来实现功耗控制。也即，执行上述S601至S603的也可以是核心网中的网元。
例如，在一些实施例中，核心网中的第一网元中可以确定第一信息，基于此，该第一网元可以基于该第一信息来确定第一配置，进而基于第一配置向其他的核心网网元、RAN节点和终端中的一个或多个发送配置信息，以此来实现对核心网、RAN和终端中的至少一个的功耗的控制。
其中，第一网元可以为核心网中目前已有的网元或者是新增的专门用于实现能量管理的网元。具体的，第一网元可以从其他的核心网网元和操作维护管理(operation administration and maintenance，OAM)收集第一信息。
另外，在该种情况下，第一网元可以按照每个UE、每个UE的每个业务、每个PDU会话或每个QoS级别等粒度从核心网网元中收集第一信息。比如，从AMF网元中收集注册终端的数量，对于每个注册的终端，可以收集该终端的特定DRX值、寻呼时间窗口、寻呼区域等。再例如，从SMF网元收集PDU会话的数量、每个PDU会话的QoS参数。再比如，从UPF网元中收集数据量和比特速率。
或者，第一网元可以按照每个网络功能(network function，NF)或每个单网络切片选择辅助信息(single network slice selection assistance information，S-NSSAI)为粒度从OAM收集第一信息，例如，可以通过OAM从RAN中收集数据量。
第一网元在收集到第一信息之后，可以基于第一信息进行计算，以确定第一能量需求。例如，对于某个业务的能耗，可以通过计算该业务对应的PDU会话的数据量与整个网络切片的总数据量的比率，并将该比率乘以该网络切片的能耗来获得。
在确定出第一能量需求之后，第一网元可以基于该第一能量需求确定出关联的第一配置，该第一配置可以是用于对终端、RAN节点、其他核心网网元进行管理的策略，之后，第一网元可以基于该第一配置向终端、RAN节点、其他核心网网元发送配置信息，相关实现过程可以参考前述介绍。
