Description

通信方法和通信装置
本申请要求于2021年03月09日提交中国专利局、申请号为202110256446.0、申请名称为“通信方法和通信装置”的中国专利申请的优先权，其全部内容通过引用结合在本申请中。
技术领域
本申请涉及通信领域，并且，更具体地，涉及通信方法和通信装置。
背景技术
无线通信系统中，网络设备需要知道用户设备(user equipment，UE)的能力信息，例如UE无线接入相关能力，或者UE核心网相关能力等。由于每个UE的能力是各不相同的，因此UE在建立连接后会将能力信息上报给网络设备，例如UE支持的最大载波聚合带宽、多入多出(multi-input multi-output，MIMO)层数、调制阶数等，在此之后网络设备会根据UE上报的能力信息进行无线资源控制(radio resource control，RRC)重配置，并采用合适的算法进行调度和通信。
当UE处于不同的场景下，需要能力更新时，UE将执行“移动注册更新”流程进行能力更新。但是该过程中UE需要重新注册到网络，会导致UE当前的业务中断，十分影响用户体验。因此，如何使得UE更加动态和灵活地进行能力更新是目前需要解决的问题。

可选地，该通信系统100包括至少两个终端设备，分别是终端设备110和终端设备130。例如D2D通信中，被调度节点是终端设备，调度节点也可以是终端设备。
本申请实施例中的终端设备可以指用户设备、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、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、增强现实(augmented reality，AR)终端、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、蜂窝电话、无绳电话、会话启动协议(session initiation protocol，SIP)电话、无线本地环路(wireless local loop，WLL)站、个人数字助理(personal digital assistant，PDA)、具有无线通信功能的手持设备、计算设备或连接到无线调制解调器的其它处理设备、车载设备、可穿戴设备，5G网络中的终端或者未来演进网络中的终端等。
其中，可穿戴设备也可以称为穿戴式智能设备，是应用穿戴式技术对日常穿戴进行智能化设计、开发出可以穿戴的设备的总称，如眼镜、手套、手表、服饰及鞋等。可穿戴设备即直接穿在身上，或是整合到用户的衣服或配件的一种便携式设备。可穿戴设备不仅仅是一种硬件设备，更是通过软件支持以及数据交互、云端交互来实现强大的功能。广义穿戴式智能设备包括功能全、尺寸大、可不依赖智能手机实现完整或者部分的功能，例如：智能手表或智能眼镜等，以及只专注于某一类应用功能，需要和其它设备如智能手机配合使用，如各类进行体征监测的智能手环、智能首饰等。
此外，终端设备还可以是物联网(internet of things，IoT)系统中的终端设备。IoT是未来信息技术发展的重要组成部分，其主要技术特点是将物品通过通信技术与网络连接，从而实现人机互连，物物互连的智能化网络。本申请对于终端设备的具体形式不作限定。
应理解，本申请实施例中，终端设备可以是用于实现终端设备功能的装置，也可以是能够支持终端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终端中。本申请实施例中，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。
本申请实施例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(Base Band 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。
应理解，本申请实施例中，网络设备可以是用于实现网络设备功能的装置，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。
本申请实施例的技术方案可以应用于各种通信系统，例如：全球移动通信(global system formobile communications，GSM)系统、码分多址(code division multiple access，CDMA)系统、宽带码分多址(wideband code division multiple access，WCDMA)系统、通用分组无线业务(general packet radio service，GPRS)、长期演进(long term evolution，LTE)系统、LTE频分双工(freq终端ncy 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)、全球互联微波接入(worldwide interoperability for microwave access，WiMAX)通信系统、第五代(5th generation，5G)系统或未来演进的通信系统，车到其它设备(vehicle-to-X V2X)，其中V2X可以包括车到互联网(vehicle to network，V2N)、车到车(vehicle to vehicle，V2V)、车到基础设施(vehicle to infrastructure，V2I)、车到行人(vehicle to pedestrian，V2P)等、车间通信长期演进技术(long term evolution-vehicle，LTE-V)、车联网、机器类通信(machine type communication，MTC)、物联网(Internet of things，IoT)、机器间通信长期演进技术(long term evolution-machine，LTE-M)，机器到机器(machine to machine，M2M)，设备到设备(device to device，D2D)等。
应理解，本申请可应用于独立部署的5G或LTE系统，也可应用于非独立部署的5G或LTE系统，例如DC场景，包括双连接(E-UTRA-NR dual connectivity，EN-DC)等，以及载波聚合(carrier aggregation，CA)场景。
图2是适用于本申请实施例的LTE系统架构示意图。
图2中的移动性管理实体(mobility management entity，MME)的功能为将寻呼消息发送到对应的eNB，空闲状态的移动性控制，非接入层信令的加密和完整性保护等。服务网关(serving gateway，SGW)支持UE移动性的用户平面数据交换等。S1接口位于eNB和MME/SGW之间，将eNB和MME相连，主要完成S1接口的无线接入承载控制、接口专用的操作维护等功能。eNB之间通过X2接口互相连接，形成了Mesh型网络。
图3是适用于本申请实施例的5G系统架构示意图。
图3中的gNB为向UE提供NR用户面和控制面协议终端的节点，并且经由NG接口 连接到5GC(5G核心网)，ng-eNB向UE提供演进的通用陆面无线接入网络(evolved universal terrestrial radio access network，E-UTRA)用户面和控制面协议终端的节点，并且经由NG接口连接到5GC。接入和移动管理功能(access and mobility management function，AMF)，负责NAS消息的加密和完保，注册、接入、移动性、鉴权、透传短信等功能，可以类比于4G的MME实体。用户面功能(user plane function，UPF)作为和数据网络的接口，完成用户面数据转发、基于会话/流级的计费统计，带宽限制等功能。即分组路由和转发以及用户面数据的服务质量(quality of service，QoS)处理等。gNB之间通过Xn接口互相连接。
图4是适用于本申请实施例的EN-DC场景示意图。
EN-DC方式将5GNR控制面锚定于4G LTE，5G NR用于承载用户面的业务。控制面就是用来发送、调度资源所需信令的通道，用户面就是传输用户数据的通道。在NSA组网下，5G基站依附现有4G核心网。
LTE基站eNB作为MN，NR基站gNB作为SN。LTE eNB与LTE系统的演进型分组核心网(evolved packet core，EPC)之间存在S1接口，至少有控制面连接(S1-Control,S1-C)，还可以有用户面连接(S1-userplan,S1-U)。NR gNB和EPC之间存在S1-U接口，即只可以有用户面连接。
图5是适用于本申请实施例的CA场景示意图。
在CA场景中可以将小区分为主小区和辅小区，主小区是工作在主频带上的小区。UE在该小区进行初始连接建立过程，或开始连接重建立过程。在切换过程中该小区被指示为主小区。辅小区是工作在辅频带上的小区。一旦RRC连接建立，辅小区就可能被配置以提供额外的无线资源。
图6是适用于本申请实施例的UE能力查询与上报流程图。
因无线通信系统中，网络设备需要知道UE的能力信息，例如UE无线接入相关能力，或者UE核心网相关能力等。由于每个UE的能力各不相同，因此UE在建立连接后会将能力信息上报给网络设备。其中，UE核心网能力在RRC连接建立时通过RRC建立完成消息发送给网络设备，网络设备再通过初始UE消息发送给核心网。
UE无线能力的查询和上报分为以下两种情况：
场景1：如果核心网中没有UE无线能力信息，并且网络设备中也没有可用的UE无线能力信息时，触发网络设备向UE发送UE能力查询消息(UECapabiliyEnquiry)，UE向网络设备上报UE能力信息(UECapabilityInformation)，该能力信息中包括UE无线能力信息。网络设备通过UE能力消息指示将UE无线能力发送给核心网，核心网保存该UE无线能力。
场景2：如果核心网中保存了UE无线能力信息，则会在初始上下文建立请求中将UE无线能力发送给网络设备。
图7是适用于本申请实施例的UE能力报告结构示意图。
具体地，若网络设备在UE能力查询消息中的reqRatList字段中请求了Nr-rat(5G)制式，UE需要在UE能力信息中上报5G制式的能力；若网络设备在UE能力查询消息中的reqRatList字段中请求了Eutra-Nr-rat(4G-5G混合组网)制式能力，UE需要在UE能力信息中上报Eutra-Nr-rat能力；若网络设备在UE能力查询消息中的reqRatList字段中请求了 Eutra-rat(4G)制式能力，UE需要在UE能力信息中上报4G制式的能力。
其中，Nr-rat的能力报告中主要包括UE的物理层参数(physical，PHY-Parameters)、射频参数(radio frequency，RF-Parameters)、分组数据汇聚协议参数(packet data Convergence protocol，PDCP-Parameters)、无线链路控制参数(radio link control，RLC-Parameters)、媒体接入控制参数(media access control，MAC-Parameters)等。
在RF-Parameters中，包含一项能力支持频段列表(supportBandCombinationList)，该能力项指示UE能够支持的频段组合(band combination，BC)列表，也就是说表示UE可以在频段组合列表中的频段组合下进行正常的业务工作。
频段组合能力中主要包括频段列表、NR载波聚合参数(caParametersNR)、特性集组合标识等。如图7所示，频段列表表示构成频段组合的每个频段的信息，每个频段的基本信息包括：频段编号，载波聚合等级。载波聚合等级指示了该频段的最大连续聚合载波数目、最大聚合带宽等；NR载波聚合参数表示NR频段载波聚合的相关能力参数；特性集组合(feature set combination，FSC)标识会指示到该频段组合对应的特性集组合，特性集组合中的每频段特性集(per band feature set)指示频段组合的每个频段的具体能力参数(也可以称之为规格)。其中，per band feature set包括的下行特性集标识会索引到该频段的下行能力参数，per band feature set包括的上行特性集标识会索引到该频段的上行能力参数。
下行特性集中的下行每载波分量特性集(feature set downlink per component carrier)标识会索引到该频段下行各个载波的下行能力参数，上行特性集中的上行每载波分量特性集(feature set uplink per component carrier)标识会索引到该频段上行各个载波的上行能力参数。载波聚合等级指示这个频段最大支持的连续聚合载波个数为K，则在该频段的上/下行特性集就包含K个上/下行每载波分量特性集标识。
需注意的是，在特性集组合中上报的是上述上/下行特性集、上/下行每载波分量特性集的标识，该标识会指向特性集池中某个具体的频段的上/下行特性集能力参数，和该频段上上/下行每载波分量特性集能力参数。这样上报的有益效果是，由于在频段和载波分量级别，包括较多相似的能力参数，因此通过标识来索引可以最大限度的节约信令开销。例如，频段A的载波聚合等级指示频段A最大支持4个下行连续聚合载波，则在下行特性集中需要上报4个每下行载波分量特性集标识的取值，这4个标识可以有相同或不同的取值。
由于NR中存在各种各样的载波聚合频段组合，为了节约UE能力信令开销，引入了回落机制。
下面对回落(fallback)机制中涉及的概念做简单介绍：
回落频段组合：对于具有相同或更低能力的频段组合，UE不需要上报具有相同或更低能力的频段组合，也不需要上报该频段组合对应的特性集。
回落per band feature set：对于给定频段，具有相同或更低能力的每频段的特性集。
回落per CC feature set：对于每频段的给定载波，具有更低的MIMO层数和带宽取值的每载波的特性集，但保持参数集(numerology)和其他参数不变。
图8是本申请实施例提供的回落频段组合示意图。
如图8所示频段组合1与频段组合2之间可以是去频段3的回落关系。除频段3之外，频段组合1与频段组合2具有相同的能力，或频段组合2具有更低的能力，此时不需要显示上报频段组合2及频段组合2对应的特性集。
频段组合1与频段组合3之间可以是频段2上去载波分量的回落关系。频段组合1与频段组合3支持相同的频段，但频段组合1在频段2上最大支持3个载波分量，频段组合3在频段2上最大支持3个载波分量中的两个载波分量，频段组合3与频段组合1相比具有相同或更低的能力，此时也不需要显示上报频段组合3及频段组合3对应的特性集。
特性集聚合机制：为了进一步节约信令开销，对于支持相同/相近频段编号和相同频段组合级别能力(如ca-ParametersNR等)的、但具有不同每频段、每载波分量能力的频段组合，支持关联到同一个特性集上，通过在per band feature set级别对应多套特性集来区分多个不同能力的频段组合。
示例地，频段组合1是频段组合2的高能力频段组合，二者除了频段编号不同(例如频段组合1支持频段1、频段2、频段3；频段组合2支持频段1和频段2)，其他频段组合级别的能力参数均相同，则频段组合1和频段组合2都可以关联到同一个特性集组合。特性集组合中per band feature set的数目和高能力频段组合中的频段数目相同，其中的per band feature set分别对应到频段1、频段2、频段3，每个per band feature set包括特性集1和特性集2，分别与频段组合1和频段组合2一一对应。每个特性集包括上/下行特性集，上/下行特性集包括每上/下行载波分量特性集。因此，频段组合2不需要显示上报，而是通过per band feature set对应的两套特性集来隐式地指示存在两套频段组合的能力。
上述示例中，频段组合1和频段组合2的频段频点可以相同，也可以不同。当频段频点不同时，例如，频段组合2中只有频段1和频段2，而没有频段3时，可将频段3对应的per band feature set的特性集2(对应频段组合2)中的上/下行特性集标识设置为0，从而表示这个该频段组合中没有频段3。
上述段落主要介绍了UE能力查询与上报流程，以及UE能力上报信令的具体解构及其含义。
当UE的无线能力更新时，将执行“移动注册更新”流程进行能力更新。然而该流程UE需要重新注册到网络，会导致当前的业务中断，十分影响用户体验。
并且，在某些场景下，UE希望能够更加动态和灵活地按照UE自身的需求改变能力。例如，UE出现过热问题或为了节电，UE希望降低峰值速率、降低载波聚合能力、降低MIMO能力；或者UE由于硬件共享需求(双卡能力共享、车联网能力共享等)，当某些RF资源和基带资源被其他系统的高优先级业务占用时，此时需改变UE的载波聚合能力(UE支持的频段组合、载波数、以及其他CA能力参数)，改变UE的双连接能力、DAPS切换能力等；或者UE受到严重的干扰问题时，需要改变载波频率；或者出于业务需求，UE从增强移动宽带业务调整到低时延高可靠业务、车联网业务或低能力业务等，从而改变能力等。
UE通过辅助信息向网络设备建议UE希望的配置。UE辅助信息可以用于解决过热问题，即UE上报更低的最大聚合带宽、最大载波数、非连续接收(discontinuous reception，DRX)配置等；或者采用UE辅助信息上报UE受到干扰的载波频率等。采用UE辅助信息避免了通过注册流程更新能力，同时避免了不必要的时延和信令开销。
但是由于辅助信息有限，并且当UE需要更新的能力参数较多时，信令开销比较大。另一方面，UE能力调整的自主权较低。是否采纳UE上报的辅助信息由网络设备自行决定，也就是说UE并不知道网络设备是否会根据UE上报的辅助信息重新配置。很可能网 络设备为了降低调度复杂度不予实现。再者UE辅助信息不能很好地支持UE在不同能力之间的灵活切换。
针对上述提及的场景，本申请提供一种可以支持UE在不同能力之间灵活切换的通信方法。
图9是本申请实施例提供的一种通信方法流程示意图。该方法900包括：
步骤S910，第一设备向第二设备发送第一信息，该第一信息包括N个不同于第一能力的能力参数集合，该能力参数集合用于第一设备向第二设备按需请求能力调整时该第一设备支持的能力参数集合，该第一能力为第一设备支持的最大能力，其中，N为大于等于1的整数。
可选地，UE在收到基站发送的UE能力查询消息后，在第一信息中上报N个能力参数集合，该第一信息为UE能力信息(UECapabilityInformation)，该UECapabilityInformation中包括UE无线能力信息。
应理解，该N个能力参数集合可指示区别于最大能力的N套能力，该N套能力可应用于硬件能力共享、过热、过冷、节电、干扰、业务调整等场景下。当然，上述场景仅为举例，本申请对此不作特别限定。
示例地，第一设备以UE为例。对于双卡能力共享场景，由于卡1和卡2会共享硬件资源，包括射频资源和基带资源。当出现双卡并发业务时，例如卡1先进行业务，当卡1检测到卡2将要发起业务时，卡1将以低于卡1最大能力的能力与网络设备通信，当并发业务停止时，卡1可以恢复到更高能力与网络设备通信。因此UE在上报UE能力时，对于每张卡，既要上报单卡工作时最高规格的能力，也要上报多卡共同工作时的能力，由于多卡之间存在硬件资源共享，因此多卡共同工作时的能力区别于单卡单独工作时的最高能力。
类似地，当UE在过热、过冷、设备内多RAT共存、节电等场景下，UE的能力会按需发生改变。因此，UE需要上报多套能力以使得UE可在多套能力之间进行灵活的切换。
可选地，N个能力参数集合包括以下RF参数中的至少一项：N个频段组合列表，该频段组合列表包括至少一个频段组合；N个特性集组合，该N个特性集组合通过对应的特性集组合标识与一个频段组合相关联；N个频段特性集，该N个频段特性集对应于频段组合中的一个频段；N个载波分量特性集，该N个载波分量特性集对应于频段组合中的一个频段的一个载波分量。
具体地，第一设备上报N个用于能力调整时支持的频段组合列表，该N个频段组合列表与第一设备按照最大能力上报的频段组合列表不同，可以是频段组合列表中包括的频段组合不同，也可以是频段组合列表中包括的频段组合相同，但频段组合的能力不同。上述N个频段组合列表中包括的频段组合可以重叠，也就是说，N个频段组合列表中的两个或者两个以上的频段组合列表可以包括相同的频段组合，该相同频段组合的能力也可以相同，也可以不同。
或者，第一设备上报N个特性集组合标识，也就是说第一设备为频段组合列表中的一个频段组合关联N个特性集组合标识。例如，第一设备除了上报频段组合1按照最大能力关联到特性集组合标识1之外，同时还上报频段组合1可关联到特性集组合标识2和特性集组合标识3。特性集组合标识2和特性集组合标识3索引到的特性集组合2和特性 集组合3，支持与特性集组合1不同的UE能力，可以是特性集组合包括的每频段具有不同能力，也可以是每频段包括的每载波分量具有不同能力。
在频段组合级别上，UE还可以通过频段组合中包括的其他参数上报多套能力。例如，对于载波聚合能力，可以上报至少一个低能力NR载波聚合参数。
或者，第一设备上报N个频段特性集。也就是说第一设备在频段组合关联的特性集组合中，例如，对该频段组合中的频段在FeatureSetsPerBand中上报N个特性集，及对应的FeatureSetDownlink和/或FeatureSetUplink。所述N个特性集中包含与最大能力不同的该频段的能力参数，上述N个特性集用于能力调整。
或者，第一设备上报N个载波分量特性集。也就是说第一设备在频段组合关联的特性集组合中，例如，对该频段组合中的频段对应的一个下行特性集FeatureSetDownlink和/或上行特性集FeatureSetUplink中上报N个下行载波分量特性集FeatureSetDownlinkPerCC和/或FeatureSetUplinkPerCC上行载波分量特性集，该N个下行载波分量特性集FeatureSetDownlinkPerCC和/或上行载波分量特性集FeatureSetUplinkPerCC包含与最大能力不同的该频段上的载波分量的能力参数，用于能力调整。
一种可能实现的方式，当上述能力参数集合包括第一能力支持的回落能力参数时，第一设备支持所述第一能力的回落能力参数。例如，第一设备上报的N个频段组合列表中的频段组合包括第一能力所支持的频段组合的回落频段组合时，该UE仍支持该第一能力的回落频段组合。假设第一设备除了按照最大能力上报的频段组合列表1之外，同时还上报频段组合列表2，和频段组合列表3。如果频段组合列表2和频段组合列表3中的频段组合具有与频段组合列表1中频段组合的相同或更低能力，则第二设备并不能认为该第一设备不支持能力回落上报机制。当第一设备在最大能力工作时，可以支持最大能力对应的频段组合列表1中频段组合的回落频段组合的能力，包括在其他频段组合列表(比如频段组合列表2和3)中显示上报的频段组合的能力。当第一设备双卡并发时，也支持频段组合列表2中频段组合的回落频段组合的能力，包括在其他频段组合列表(比如频段组合列表3)中上报的频段组合的能力。例如，如果该N个频段特性集包括第一能力所支持的频段特性集的回落频段特性集时，该第一设备仍支持该第一能力的回落频段特性集，即第二设备并不能认为该第一设备不支持回落的能力上报机制。例如，当该N个载波分量特性集包括第一能力所支持的载波分量特性集的回落载波分量特性集时，该第一设备仍支持该第一能力的所有回落载波分量特性集，即第二设备并不能认为该第一设备不支持回落的能力上报机制。
另一种可能实现的方式，步骤S920，该第一设备向第二设备发送第二信息，该第二信息指示该第一设备支持第一能力的回落能力。上述一种可能实现的方式中N个能力参数集合包括或者不包括第一能力支持的回落能力参数，该第一设备都支持第一能力的回落能力，第二设备应认为第一设备支持第一能力的回落能力；而另一种可能实现的方式中是通过第二信息显示的指示该第一设备支持第一能力的回落能力。
可选地，N个能力参数集合除了包括RF参数外，还包括以下至少一项：至少一个分组数据汇聚协议(packet data convergence protocol，PDCP)序列号长度；至少一个无线链路控制(radio link control，RLC)序列号长度；至少一个混合自动重传请求(hybrid automatic repeat request，HARQ)进程数目。
应理解，假设第一设备上报最大能力的参数集合中有X项能力参数，上述N个能力参数集合只对于其中的可能发生变化的M项能力参数上报不同的取值，M≤X。上述可选的方案中该M＝4。
当然，该N个能力参数集合还可以包括按照协议层和应用制式分类的其它能力参数，这些能力参数可包括，发射能力和接收能力，可以包括基带处理能力和RF能力，可以包括天线数、发送功率等级(power class)、补充上行载波(Supplementary Uplink Carrier，SUL)相关参数、双连接(Dual Connectivity，DC)相关参数、频段相关参数、DRX配置、MIMO层数、带宽、聚合载波数、调制阶数、双工方式、物理层的调度和处理的偏移参数、参考信号配置等。上述参数仅为举例，该N个能力参数集合中还可以包括其他用于表征第一设备能力的参数，本申请对此不作任何限定。
可选地，将N个能力参数集合与第一设备的能力模式相对应。每个能力模式对应一组能力参数集合，能力模式还对应一个能力调整原因或能力调整目的，比如，适用于第一设备过冷或温度过低时的能力模式；适用于第一设备过热或温度过高时的能力模式；适用于节能的能力模式；适用于NR和无线局域网(wireless local area network，WLAN)能力共享时的能力模式；适用于多用户身份模块(subscriber identity module，SIM)卡能力共享时的能力模式；适用于车对万物(vehicle to everything，V2X)能力共享时的能力模式；适用于超高可靠低时延(ultra-high reliability and low latency，URLLC)业务的能力模式；适用于低能力(reduced capability，REDCAP)业务的能力模式。当然，该能力模式还可包括其他模式，在此不做一一举例。
示例地，可以为每个能力模式关联特定的频段组合，和/或特性集组合，和/或per band feature set，和/或per CC feature set。例如，在UE能力信息上报时，为每个能力模式关联不同能力的频段组合列表，UE上报每个能力模式所支持的频段组合列表，比如上报能力模式1支持频段组合列表1，频段组合列表1中包括频段组合1和频段组合2，能力模式2支持频段组合列表2，频段组合列表2包括频段组合1和频段组合3。
或者，每个能力模式可以关联相应的特性集组合标识。例如，UE在能力信息中指示每个能力模式下频段组合所关联的特性集组合标识。比如，假设UE共有三个频段组合，UE指示能力模式1下频段组合1关联特性集组合1，频段组合2关联特性集组合1，频段组合3关联特性集组合2；能力模式2下频段组合1关联特性集组合1，频段组合2关联特性集组合2，频段组合3关联特性集组合3。
或者，每个能力模式可以关联不同能力的per band feature set。例如，UE上报频段组合的每个频段所关联的特性集标识，并指示其关联到某个特定的能力模式。比如，假设UE在频段组合1下有1个频段1：能力模式1下，频段1对应的为特性集标识1关联的特性集；能力模式2下，频段1对应的为特性集标识2关联的特性集。
或者，每个能力模式可以关联per CC feature set。例如，UE上报频段组合的频段的每个载波分量所关联的下行载波分量特性集FeatureSetDownlinkPerCC和/或上行载波分量特性集FeatureSetUplinkPerCC标识，并指示其关联到某个特定的能力模式。比如，假设UE在频段组合1下有1个频段1，频段1中有一个载波分量1：能力模式1下，载波分量1对应的下行方向的特性集为下行每载波分量特性集标识1，上行方向的特性集为上行每载波分量特性集标识1；能力模式2下，载波分量1对应的下行方向的特性集为下行每载 波分量特性集标识2，上行方向的特性集为CC下行每载波分量特性集标识2。
可选地，能力模式关联的能力参数集合中除了以上述方式关联相应的射频能力参数之外，第一设备的能力模式关联的能力参数集合中还可以包括如下与最大能力不同的能力参数：例如，针对过热模式，包含一个与最大能力不同的的DRX配置、物理层调度和处理偏移参数能力、上/下行最大载波数、MIMO层数中的一个或多个参数；针对过冷模式，包含MIMO层数、上/下行最大载波数、上/下行最大带宽、最大子载波间隔、微时隙(mini-slot)相关参数、支持的频段号中的一个或多个参数；针对双卡能力共享，包含双卡并发时的发射能力和接收能力，包括如HARQ进程数目、PDCP序列长度、RLC确认模式下的序列长度、信道状态信息(channel state information，CSI)处理能力、网络协助的干扰抵消和抑制(network-assisted interference cancellation and suppression，NAICS)能力、用于测量的参考信号配置、双连接(In-device coexistence，DC)能力、UE类型(User Equipment Category，UE CAT)、MIMO能力、信道探测参考信号(sounding reference signal，SRS)发送切换能力、上/下行最大载波数目、上/下行最大带宽、MIMO层数、发送功率等级、补充上行载波(Supplementary Uplink Carrier，SUL)参数中的一个或多个能力参数；针对低能力UE，包括低能力支持的带宽、收发天线数、上下行的调制阶数、双工方式中的一个或多个能力参数等。
可选地，该方法900还包括：
步骤S930，第一设备确定能力发生变化，或确定该第一设备的能力需要发生变化。例如，当第一设备进入双卡并发态，或进入车联网业务占用了部分基带资源或RF资源，或发生过热/冷，或第一设备为了节电，或发生设备内共存干扰，或UE类型调整为低能力UE或业务类型调整为低时延高可靠等。
步骤S940，当第一设备确定能力发生变化，或确定该第一设备的能力需要发生变化后发送第三信息给第二设备，对应的，第二设备接收该第三信息，第三信息指示第一设备调整后或需调整至的能力参数集合标识或能力参数标识，该能力参数集合标识为所述N个不同于第一能力的能力参数集合中的其中一个能力参数集合的标识，该能力参数标识为所述N个不同于第一能力的能力参数集合中的能力参数的标识。应理解，若第一设备上报的能力参数集合关联第一设备的能力模式时，当第一设备确定能力发生变化时，第一设备向第二设备指示第一设备调整后或需调整至的能力模式。例如，指示为能力模式1，则表示第一设备调整后或需调整至的能力模式1对应的能力参数集合。以RF参数举例，可以是调整后或需调整至的能力支持的频段组合列表(其中包含当前正在工作的频段组合)，和/或支持的特性集组合，和/或支持的per band feature set，和/或per CC feature set。
该方式可以直接通过低层信令(MAC层或PHY层)指示能力模式，例如通过一个位图指示。例如存在4个能力模式，分别为能力模式0至能力模式3，用2比特的比特位图00,01,10,11指示上述四个能力模式。该方案可以实现更加快速的能力调整，时延更低。对于硬件能力共享的场景，如果有高优先级业务占用了部分硬件能力，则可以更快地动态调整能力，降低对当前业务的影响。
还应理解，当第一设备上报的N个能力参数集合没有关联第一设备的能力模式时，第一设备发送的第三信息指示该第一设备调整后或需调整至的能力参数集合的标识，该能力参数集合标识为所述N个不同于第一能力的能力参数集合中的其中一个能力参数集合的 标识。
还应理解，第一设备发送的第三信息可以直接指示该第一设备调整后或需调整至的能力参数的标识信息。
可选地，该第三信息指示的能力参数标识包括以下至少一项：频段组合列表标识；频段组合；频段组合对应的特性集组合标识；频段组合内频段对应的per band feature set标识；频段组合内频段的载波分量对应的per CC feature set标识。
可选地，该方法900还包括：
步骤S950，第一设备发送第四信息给第二设备，该第四信息指示该第一设备能力调整的原因或目的。能力调整的原因或目的包括以下的至少一项：硬件能力共享、过热、过冷、节电、干扰、UE类型调整、业务类型变更。
应理解，第四信息和第一信息可以是同一信息，或者说第四信息和第一信息承载于同一消息中，第四信息和第一信息也可以是不同信息，或者说第四信息和第一信息承载于不同消息中；第四信息和第三信息可以是同一信息，或者说第四信息和第三信息承载于同一消息中，第四信息和第三信息也可以是不同信息，或者说第四信息和第三信息承载于不同消息中，本申请对此不做特别限定。
一种可能实施的方式，S910步骤中，第一设备上报一个低能力频段组合列表。该低能力频段组合列表中包括所有场景下可能使用的低能力频段组合，当第一设备能力发生改变时，第一设备向第二设备发送第三信息指示调整后的能力支持的一个或多个频段组合序号(其中应包含当前正在工作的频段组合)，或指示当前挂起的频段组合序号。挂起表示UE能力暂时不支持。
另一种可能实施的方式，S910步骤中，第一设备上报N个不同于第一能力的频段组合列表。当第一设备能力发生改变时，第一设备向第二设备发送的第三信息指示调整后的第一设备能力支持的频段组合列表。其中，该频段组合列表中可以包括当前正在工作的频段组合。或第一设备向第二设备指示挂起一个或多个频段组合列表。
另一种可能实施的方式，S910步骤中，第一设备上报N个特性集组合，所述N个特性集组合通过对应的特性集组合标识与一个频段组合相关联。，当第一设备能力发生改变时，第一设备向第二设备发送的第三信息指示调整后的第一设备的能力支持使用的频段组合(其中应包含当前正在工作的频段组合)及对应的特性集组合标识，或指示挂起频段组合对应的特性集组合标识。在该方式下，若第一设备的频段组合级别能力发生改变，则同时指示第一设备能力调整为低能力NR载波聚合参数。
另一种可能实施的方式，S910步骤中，第一设备上报N个频段特性集(per band feature set)，所述N个频段特性集对应于频段组合中的一个频段。当第一设备能力发生改变时，第一设备向第二设备发送的指示信息指示当前第一设备工作的频段组合(其中应包含当前正在工作的频段组合)对应的特性集组合中，频段支持的某一个或多个per band feature set标识，或指示挂起的某一个或多个per band feature set标识。
另一种可能实施的方式，S910步骤中，第一设备上报N个载波分量特性集(per CC feature set)，所述N个载波分量特性集对应于频段组合中的一个频段的一个载波分量。当第一设备能力发生改变时，第一设备向第二设备发送的第三信息指示当前第一设备能力支持的频段组合(其中应包含当前正在工作的频段组合)对应的特性集组合中，频段支持的某 一个或多个per CC feature set标识，或指示挂起某一个或多个per CC feature set标识。
第三信息指示该第一设备调整后或需调整至的能力参数的这种方式，可以将能力模式与能力参数解耦，在能力调整时直接指示第一设备当前能力支持的能力参数。该方式的好处是当第一设备处于耦合的能力模式时，比如既处在双卡并发态，又处在过热态，则可以更加灵活地调整能力。
可选地，该方法900还包括：
步骤S960，该第一设备接收来自第二设备的响应信息，或该第一设备在发送该第三信息后的第一时长内未收到该响应信息，该响应信息指示该第二设备允许该第一设备的能力调整至该能力参数集合标识对应的能力参数集合或调整至该能力参数标识对应的能力参数。此后该第一设备根据调整后的能力参数集合或能力参数与该第二设备通信。
具体地，UE在发送第三信息之后，在第一时长(比如一个定时器时长)内等待第二设备反馈的响应消息。对应地，第二设备在收到UE发送的第三信息后，发送响应信息。
应理解，该定时器可以是第二设备配置的或UE实现的。在定时器超时后，UE主动进行能力调整，按照调整后的能力参数集合与第二设备通信。
步骤S970，第二设备根据该第三信息变更对第一设备的配置。
可选地，变更RRC配置，例如第二设备通过向第一设备发送RRC重配置消息，该RRC重配置消息基于第一设备调整后的能力参数对所述第一设备进行重配置。更改RRC连接的配置包括建立/修改/释放无线承载、同步的重配、测量的重配、小区和小区组的重配、切换的重配等。
图10是本申请实施例提供的另一种通信方法流程示意图。该方法1000包括：
步骤S1010，第一设备确定能力发生变化，或确定该第一设备的能力需要发生变化。例如，当第一设备进入双卡并发态，或进入车联网业务占用了部分基带资源或RF资源，或发生过热/冷，或第一设备为了节电，或发生设备内共存干扰，或设备类型调整为低能力设备或业务类型调整为低时延高可靠等。
步骤S1020，第一设备向第二设备发送第一信息，该第一信息包括N个不同于第一能力的能力参数集合，该能力参数集合用于第一设备向第二设备按需请求能力调整时该第一设备支持的能力参数集合，该第一能力为第一设备支持的最大能力，其中，N等于1。
应理解，当确定第一设备的能力发生变化或需要发生变化时，第一设备通过第一消息向第二设备上报第一设备调整后或需调整至的一个能力参数集合。
可选地，该能力参数集合中可以包括第一设备调整后或需调整至的RF参数，该RF参数包括以下参数的至少一项：频段组合、特性集组合、频段的特性集组合、载波的特性集组合。
可选地，能力参数集合还可以包括以下至少一项：PDCP SN长度；RLC SN长度；HARQ进程数目；DRX配置；物理层调度和处理偏移参数能力；CSI处理能力；NAICS能力；用于测量的参考信号配置；DC能力；UE CAT；MIMO能力；信道探测参考信号(sounding reference signal，SRS)发送切换能力；最大聚合载波数目；最大聚合带宽；MIMO层数；带宽；收发天线数；上下行的调制阶数；双工方式；发送功率。
可选地，该方法1000还包括：
步骤S1030，第一设备发送第四信息给第二设备，该第四信息指示该第一设备能力调 整的原因或目的。能力调整的原因或目的包括以下的至少一项：硬件能力共享、过热、过冷、节电、干扰、UE类型调整、业务类型变更。
应理解，第四信息和第一信息可以是同一信息，或者说第四信息和第一信息可以承载于同一消息中，第四信息和第一信息也可以是不同信息，或者说第四信息和第一信息承载于不同消息中，本申请对此不做特别限定。
可选地，该方法1000还包括：
步骤S1040，该第一设备接收来自第二设备的响应信息，或该第一设备在发送该第一信息后的第一时长内未收到该响应信息，该响应信息指示该第二设备允许该第一设备的能力调整至该能力参数集合对应的能力参数。此后该第一设备根据调整后的能力参数集合与该第二设备通信。
具体地，UE在发送第一信息之后，在第一时长内(比如一个定时器时长)内等待第二设备反馈的响应消息。对应地，第二设备在收到UE发送的第一信息后，发送响应信息。
应理解，该定时器可以是第二设备配置的或UE实现的。在定时器超时后，UE主动进行能力调整，按照调整后的能力参数集合与第二设备通信。
步骤S1050，第二设备根据该第一信息变更对第一设备的配置。
可选地，变更RRC配置，例如第二设备通过向第一设备发送RRC重配置消息，该RRC重配置消息基于第一设备调整后的能力参数对所述第一设备进行重配置。更改RRC连接的配置包括建立/修改/释放无线承载、同步的重配、测量的重配、小区和小区组的重配、切换的重配等。
方法900中第一设备在能力变化或者能力需要变化前向第二设备上报N个能力参数集合，从而第二设备可预知第一设备可能会调整至的能力，相较于方法1000中第一设备在能力变化或者能力需要变化后上报能力参数集合而言，可以降低第二设备调度的复杂度。
