Description

能力信息上报方法及其装置
本申请要求于2020年05月18日提交中国国家知识产权局、申请号为202010421049.X、发明名称为“能力信息上报方法及其装置”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
本申请实施例涉及通信技术领域，具体涉及一种能力信息上报方法及其装置。
背景技术
载波聚合(carrier aggregation,CA)是增加传输带宽的技术，在长期演进(long term evolution,LTE)系统、高级长期演进(long term evolution-advanced,LET-A)系统以及新无线(new radio,NR)系统中，都引入了载波聚合，从而使得一个终端设备可以同时在多个载波上进行数据传输。
现有技术中，按照用户设备(user equipment,UE)支持的载波个数和每个载波上最大支持的信道带宽确定UE的能力信息，各个载波之间能力相互独立，UE设计存在较大的冗余信息。在载波聚合场景，UE在上报载波聚合能力信息时，根据现有的协议规定，UE根据在频段(band)内的每个载波(在载波聚合中，参与聚合的载波也称为分量载波(component carrier,CC))的最大支持带宽设计对应的处理能力，上报该处理能力信息。但在实际数据传输的过程中，针对单一载波的调度的带宽往往达不到分量载波的最大支持带宽，这造成了UE能力不必要的浪费，导致UE的设计成本增加。
发明内容
本申请实施例提供了一种能力信息上报方法，可以应用于通信系统，例如，长期演进系统LTE、新无线NR系统、演进的通用陆基无线接入及新空口的双连接(E-UTRA-NR dual connectivity，EN DC)的通信系统，高可靠低时延通信系统(ultra reliability low latency communication，URLLC)、车与任何事物(vehicle to everything，V2X)通信系统、长期演进与车(LTE-vehicle，LTE-V)通信系统、新无线与车(NR-vehicle，NR-V)通信系统、车对车(vehicle-to-vehicle，V2V)、车联网、海量机器类通信(massive machine type of communication，mMTC)、物联网(internet of things，IoT)、基于LTE演进的物联网技术(LTE-machine to machine，LTE-M)，机器与机器(machine to machine，M2M)设备与设备(device to device,D2D)通信系统等。本申请实施例提供的方法用于被调度节点向调度节点发送能力信息时，根据能力信息中包含的最大聚合频谱的能力信息，合理的调度资源，进而减少了终端设备的能力浪费，降低了终端设备的成本。

具体实施方式
为了方便理解本申请实施例，首先介绍本申请涉及的术语。
载波：如无特别说明，本申请实施例中的载波指频域上连续的一段频谱。例如，在3GPP NR协议下，载波就等同于3GPP NR中定义的载波(carrier)或者分量载波(component carrier，CC)，载波还可以指代一个带宽部分(band width part,BWP),载波还可以指代对应于一个小区cell、一个信道channel、一个子信道sub-channel、一个或者多个资源块(resource block，RB)、资源块组(resource block group，RBG)，该资源块组可以是物理上连续的，如物理资源块(physical resource lock，PRB)，或者是物理上不连续，但是通过一定的映射规则映射到虚拟的连续的资源上的，例如虚拟资源块(virtual resource block，VRB)。对于本申请提供的实施例，分量载波，BWP，资源块，资源块组、信道、子信道等各种频域上一段连续频谱的不同称谓，实施效果相同。为了方便描述，不做重复说明。
数据传输：数据传输包括发送数据和/或接收数据。
载波生效：如无特别说明，本申请实施例中的载波生效，指该载波(含义包括载波，分量载波，BWP，资源块，资源块组、信道、子信道等各种频域上一段连续频谱的不同称谓)被第一设备和第二设备双方确定为工作状态，该工作状态可以是被配置、被激活或者被使能中的一个或者多个，具体的，该载波生效包括：
载波被配置：第二设备通过高层信令(如无线资源控制消息)通知第一设备该载波的配置信息(包括带宽、中心频率等信息)。
载波被激活：第二设备通过高层信令、媒体接入控制(media access control，MAC)信令或者物理层信令中的一个通知终端设备激活该载波，被激活也可称为被使能。
如无特别说明，为了方便描述，本申请实施例中以载波生效以载波被配置为例进行说明。
频谱处理资源：本申请实施例中所述的频谱处理资源，指终端设备处理频谱所需要用到的终端设备的处理资源，例如终端设备中央处理器中的处理资源，可以理解的是，频谱处理资源还可以包括终端设备中其它的处理资源，例如存储器资源等，具体此处不做限定。
载波聚合：本申请实施例中所述的载波聚合，是指终端设备支持多余一个载波的同时被调度或被处理，并不限定在一个无线接入技术下。这里的载波，又称分量载波(component carrier,CC)。例如这些载波可以是支持同一个无线接入技术(radio access technology，RAT)的，如都是支持NR无线接入技术的载波；也可以是这次支持不同RAT的，例如一个是LTE的载波，一个是NR的载波；多个载波可以是属于同一个小区组(cell group，CG)，也可以是属于不同CG的,例如一个载波在主CG，一个载波在辅CG；多个载波可以是属于同一个频段的，也可以是不同的频段的；多个载波可以是用于用一个连接的通信，也可以是用于不同连接的通信，例如多模双连接(multi-radio dual connectivity,MR-DC)，一个载波用于LTE连接的通信，另一个载波用于NR连接的通信；多个载波可以是用于相同链路的通信，也可以是用于不同的链路的通信，例如一个载波用于蜂窝链路Uulink，一个载波用于侧行链路 sidelink；多个载波可以是用于同一类型业务的通信，也可以是用于不同的业务的通信，例如一个载波用于增强型移动带宽接入(enhanced mobile broadband，eMBB)业务，一个载波用于车联网业务，一个载波用于高可靠低时延通信业务，一个载波用于海量物联网业务(massive internet of thing，mIoT)；或者一个载波用于eMBB业务和URLLC业务，一个载波用于V2X业务，等等。
为了更好的理解本申请实施例公开的一种能力信息上报的方法，下面首先对本申请实施例适用的通信系统进行描述。
请参见图1，图1为本申请实施例提供的一种通信系统的架构示意图。该通信系统可包括但不限于一个网络设备和一个终端设备，图1所示的设备数量和形态仅用于举例并不构成对本申请实施例的限定，实际应用中可以包括两个或两个以上的网络设备，两个或两个以上的终端设备。图1所示的通信系统以包括一个网络设备102和多个终端设备101为例进行说明。
需要说明的是，本申请实施例的技术方案可以应用于各种通信系统。例如：LTE系统、第五代(5th generation，5G)移动通信系统、5G NR系统，或者其他未来的新型移动通信系统等。该通信系统还可以是支持多种无线技术的通信系统，例如支持LTE和NR的通信系统；或者，该通信系统还可以是支持近距离通信的通信系统，例如，支持侧行链路(sidelink，SL)技术的通信系统，支持无线保真(wireless fidelity，WiFi)技术的通信系统等等。还需要说明的是，本申请实施例中的侧行链路还可以称为侧链路或直通链路。
本申请实施例中的网络设备102是网络侧的一种用于发射或接收信号的实体。例如，网络设备102可以为演进型基站(evolved NodeB，eNB)、传输点(transmission reception point，TRP)、NR系统中的下一代基站(next generation NodeB，gNB)、发送接收点(transmission reception point，TRP)、中继节点(relay node,RN)、接入点(access point，AP)、其他未来移动通信系统中的基站或WiFi系统中的接入节点等。本申请的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。
本申请实施例中的终端设备101是用户侧的一种用于接收或发射信号的实体，如手机。终端设备也可以称为终端(terminal)、用户设备(user equipment，UE)、移动台(mobile station，MS)、移动终端(mobile terminal，MT)等。终端设备可以是具备通信功能的汽车、智能汽车、手机(mobile phone)、穿戴式设备、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、远程手术(remote medical surgery)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。本申请的实施例对终端设备所采用的具体技术和具体设备形态不做限定。
在图1的通信系统中，一种可选的实现方式中，终端设备101向网络设备102上报自己的能力信息，网络设备102根据终端设备101上报的能力信息进行资源调度，进而和终端设备101进行通信。
在另一种可选的实现方式中，终端设备101具有调度功能。在终端设备101和其他终端设备直接进行通信的过程中，终端设备101接收其他终端设备发送的能力信息，终端设备101 根据其他终端设备发送的能力信息确定需要调度的资源，并根据该确定需要调度的资源与其他终端设备进行通信。其中，终端设备101和其他终端设备直接进行通信表示终端设备101和其他终端设备传输信息时，不需要经过网络设备102进行信息的转发，而直接进行信息的交互。例如在车与任何事物通信系统V2X的场景下，或者机器与机器M2M的场景下等等。
下面结合附图对本申请实施例提供的能力信息上报方法及其装置进行详细地描述。
本申请实施例中，第一设备在上报能力信息之后，对应的能力信息可能会发生变化，需要重新向第二设备上报新的能力信息，因此，对应的方法也有所不同，本申请实施例将对几种不同的情况分别进行描述。
一、第一设备上报能力信息。
本实施例中，以第一设备为终端设备、第二设备为网络设备为例进行描述。请参见图2，图2是本申请实施例提供的一种能力信息上报方法的流程示意图。
在步骤201中，终端设备确定能力信息。
终端设备确定终端设备的能力信息，该能力信息具体包括终端设备在至少一个第一范围内支持的最大聚合频谱的能力，即该最大聚合频谱表示终端设备在第一范围内能够支持的总频谱，该总频谱小于第一带宽，该第一带宽表示终端设备在第一范围内支持的频段或者频段组合内各个聚合载波的最大带宽的和。
需要说明的是，在本申请的全部实施例中，载波的概念可以等同于分量载波，以下全部用载波来描述，本申请并不局限于此，在此不再赘述。
终端设备可以通过如下公式计算该最大聚合频谱：
Figure PCTCN2021093766-appb-000001
其中，J为终端设备支持的在第一范围内的频段或者频段组合内总的聚合载波的数量，BW (j)为终端设备载波j的最大带宽，载波j为终端设备支持的在第一范围内的频段或者频段组合内的一个载波，
Figure PCTCN2021093766-appb-000002
为终端设备支持的在第一范围内的频段或频段组合内的所有载波聚合的各个分量载波的最大带宽的和，
Figure PCTCN2021093766-appb-000003
表示遍历终端设备支持的，在第一范围内的所有频段或频段组合的所支持的载波聚合的各个分量载波的最大带宽的和。
举例来说，如表1所示，如终端设备支持频段A，频段B，频段C，频段组合{频段A+频段B}和频段组合{频段A+频段B+频段C}的载波聚合。J表示终端设备在对应的频段中支持的分量载波数。频段A内支持1个载波，频段B内支持2个载波，频段C内支持1个载波，若每个分量载波的最大带宽均为100MHz，则在终端设备在频段组合{频段A+频段B+频段C}所支持的载波聚合的各个分量载波的最大带宽的和为400MHz，遍历终端设备所支持的所有的频段和频段组合内的载波聚合，可知该值为400MHz。本发明的实施例，确定最大聚合频谱小于400MHz。
表1终端设备支持的频段和频段组合的最大带宽对应示意表
Figure PCTCN2021093766-appb-000004
本申请实施例中，还可以通过PRB的大小来表示最大聚合频谱，例如通过如下公式计算该最大聚合频谱：
Figure PCTCN2021093766-appb-000005
其中，J为终端设备支持的在第一范围内所的频段或者频段组合内的载波聚合总的载波的数量，μ表示子载波间隔，
Figure PCTCN2021093766-appb-000006
表示对于参数μ，载波j的信道带宽BW对应的最大RB数量，在一种可实现的方式中，
Figure PCTCN2021093766-appb-000007
N RB的取值如表2a和表2b所示，其中，μ表示不同的子载波间隔SCS。

表2b不同的子载波间隔对应的最大资源块数量表
Figure PCTCN2021093766-appb-000009
在一种可能的实现方式中，终端设备的能力信息还包括终端设备的频谱处理资源的信息。该频谱处理资源表示终端设备接收和/或发送数据时使用的终端设备的本地资源，该本地资源可以包括例如处理器资源，和/或存储器资源，具体此处不做限定。该频谱处理资源具体可以包括接收一个载波承载的信号所用的处理资源(称为设备下行频谱处理资源或接收频谱处理资源)，或者发送一个载波上承载的信号所用的处理资源(设备上行频谱处理资源或者发送频 谱处理资源)中的至少一种。在设备与设备通信(如D2D场景或者V2V场景)中，频谱处理资源还可以称为侧行链路处理资源。
其中，设备接收频谱处理资源包括接收存储资源或接收处理资源中的至少一个，接收存储资源可以包括以下至少一个：基带采样后数据存储资源、解调后数据软比特存储资源、解码后传输块存储资源等，可以理解的是，接收存储资源还可以包括更多的资源，例如高层数据包存储资源，具体此处不做限定。
接收处理资源可以包括以下至少一个：射频处理资源、前端处理资源、信道估计处理资源、解调处理资源、译码处理资源、解密处理资源、测量处理资源等。对于信道估计处理资源，可以包括以下至少一种：PDCCH的信道估计资源，PDSCH的信道估计资源，PSCCH的信道估计资源，PSDCH的信道估计资源。对于解调处理资源，可以包括以下至少一种：PDCCH的解调资源，PDSCH的解调资源，PSCCH的解调资源，PSDCH的解调资源。译码处理资源可以包括polar码译码单元和/或LDPC译码单元。可以理解的是，接收处理资源还可以包括更多的资源，例如信道状态计算处理资源，协议栈处理资源等，具体此处不做限定。
设备发送频谱处理资源包括发送存储资源和/或处理资源。发送存储资源可以包括以下至少一个：高层数据包的存储资源，MAC层数据包的存储资源，传输块的存储资源。可以理解的是，发送存储资源还可以包括更多的资源，例如编码后的数据存储资源，调制后的数据存储资源，映射后的数据存储资源等，具体此处不做限定。
设备发送频谱处理资源可以包括以下至少一个：包括射频处理资源、功放处理资源、前端处理资源、加密处理资源、数据组包处理资源、编码处理资源、调制处理资源、发射功率控制处理资源等。可以理解的是，设备发送频谱处理资源还可以包括其他资源，例如包括处理各个信道所需要用到的资源，如PUSCH信道处理资源，PUCCH信道处理资源，PSCCH处理资源，PSDCH处理资源。在实际应用过程中，设备发送频谱处理资源还可以包括更多的处理资源，具体此处不做限定。
在一种可能的实现方式中，终端设备的能力信息还包括第一指示信息，第一指示信息用于指示该终端设备的第一范围。终端设备可以支持至少一个第一范围。第一范围为终端设备可以支持的根据一个或者多个频段所确定的频率范围。例如，终端设备的射频器件工作支持的范围是频段A，则第一范围为频段A。可以理解的是，还可以根据终端设备的其他器件能够支持的频段来确定第一范围，例如终端设备的天线和/或基带处理器等，具体此处不做限定。
可选地，第一范围的划分可以和现有协议中的频率范围(frequency range,FR)相同，例如和3GPP NR协议中的FR1和FR2划分一致，如表3所示，此时，第一范围为FR1所表示的频率范围，或者第一范围为FR2所表示的频率范围，或者合并FR1和FR2所表示的总的频率范围。
表3 3GPP NR协议定义的FR1和FR2对应的频率的范围
Figure PCTCN2021093766-appb-000010
终端设备可以支持至少一个第一范围。具体的，在一种可能的实现方式中，如表4所示，终端设备支持FR1，或终端设备支持FR2，或终端设备支持FR1和FR2。终端设备在第一范围 内支持的最大聚合频谱的能力，例如，终端设备在FR1内支持的最大聚合频谱，或者，终端设备在FR2内支持的最大聚合频谱，或者，终端设备在FR1和FR2共同确定的范围，也就是所有的频段范围内支持的最大聚合频谱。
表4第一范围与最大聚合频谱的对应关系示意表
Figure PCTCN2021093766-appb-000011
可选的，在一种可能的实现方式中，第一范围还可以包括一个或者多个频段的集合。例如，第一范围1为集合A，第一范围2为集合B，集合A＝{n34,n36,n40,n41}，集合B＝{n77,n78,n79}，其中，n34,n36,n40,n41，n77,n78,n79分别表示不同的频段，需要说明的是，多个第一范围包括的集合中的频段可以是重叠的，例如集合A＝{n34,n36,n40,n41}，集合B＝{n41，n77,n78,n79}，即n41这个频段既在第一范围1中，也在第一范围2中。其中，n34,n36,n41,n77,n78和n79为按照3GPP NR 38.101所定义的频段编号，详见TS 38.101-1。
在一种可能的实现方式中，第一范围还可以根据终端设备支持的空口接入协议，例如无线接入技术(radio access technology，RAT)来定义。例如，对于支持LTE和NR双连接的终端设备，如果终端设备支持所有LTE的频段和/或频段组合与NR的部分频段和/或频段组合之间共享终端设备的频谱处理资源，则将这些可以共享频谱处理资源的LTE的频段和/或频段组合与NR部分的频段和/或频段组合定义为第一范围，可以理解的是，还可以是部分LTE的频段和/或频段组合与全部NR的频段和/或频段组合定义为第一范围，只要各个空口接入协议频段和/或频段组合之间可以共享终端设备的设备频谱处理资源即可，具体此处不做限定。对于支持LTE和NR双连接的终端设备，还可以是在LTE内的所有频段或频段组合的载波间共享设备频谱处理资源，NR内的所有频段或频段组合的载波间共享处理能力，但LTE和NR之间的载波不能共享处理能力。其中几个根据终端设备支持的空口协议来定义第一范围的例子如下表5所示。
表5第一范围与最大聚合频谱的对应关系示意表
Figure PCTCN2021093766-appb-000012
在一种可能的实现方式中，第一范围还可以根据终端设备支持的连接(connection)来定义。例如，支持MR-DC的终端设备，支持两个NR的连接,若两个NR连接中，终端设备支持的频段和/或频段组合可以共享频谱处理资源，则将支持MR-DC的终端设备的两个NR连接的频段，和/或，频段组合定义为第一范围。可以理解的是，如果终端设备的多个连接之间的频段和频段组合可以共享频谱处理资源，则将这些可以共享频谱处理资源的连接定义为第一频率资源。当然如果两条NR连接之间不能共享处理资源，但连接内可以共享频谱处理资源，则可以共享处理资源的连接内所支持的频段和/或频段组合定义为一个第一范围。
在一种可能的实现方式中，第一范围还可以根据终端设备支持的链路类型来定义。例如支持蜂窝空口链路Uu link和侧行链路sidelink的终端设备的Uulink的频段，和/或，频段组合与sidelink的频段，和/或，频段组合之间可以共享频谱处理资源，则将Uu link和sidelink定义为第一范围，或者将可以共享频谱处理资源的Uu link和sidelink的频段，和/或，频段组合定义为第一范围。Uu link和Sidelink所支持的频段和/或频段组合内的载波间可以共享频谱处理资源。举例如下表6所示。
表6第一范围与最大聚合频谱的对应关系示意表
Figure PCTCN2021093766-appb-000013
在一种可能的实现方式中，第一范围还可以根据终端设备支持的业务类型，或者称为支持的应用场景或者支持的特性来定义，例如对于支持eMBB业务和支持V2X特性的终端设备，该终端设备在eMBB场景下支持的频段和/或频段组合与在V2X场景下支持的频段和/或频段组合有部分或者全部的频段和/或频段组合可以共享频谱处理资源的，则将这些可以共享频谱处理资源的频段和/或频段组合定义为第一范围。
在一种可能的实现方式中，可以通过以下表7来定义多个频率范围。这里的频率范围的划分的举例，根据业界大部分终端设备是否能够共享射频器件划分。例如对频谱小于1GHz的无线信号的接收，可以共用相同的接收射频通道。则将小于1GHz的无限信号划分为一个频率范围，以此类推。
表7频率范围和对应频谱范围对应示意表
频率范围 频谱范围
频率范围Frequency Range 1 <1GHz
频率范围Frequency Range 2 1GHz-3GHz
频率范围Frequency Range 3 3GHz-5GHz
频率范围Frequency Range 4 5GHz-8GHz
频率范围Frequency Range 5 10GHz-30GHz
频率范围Frequency Range 6 30GHz-45GHz
频率范围Frequency Range 7 45GHz-75GHz
频率范围Frequency Range 8 70GHz-80GHz
第一范围可以定义为一个或多个频率范围，第一范围内的载波可以进行频谱处理资源的共享，例如当第一范围包括按照表7所指示的FR1，FR2，FR3，FR4时，则终端设备在FR1、FR2,FR3和FR4中支持的载波间共享频谱处理资源。FR1，FR2，FR3，FR4所指示的频谱范围为小于8GHz，当第一范围定义为FR1,FR2,FR3,FR4时，即表示在小于8GHz的聚合载波间共 享频谱处理资源。
可以理解的是，第一范围由可以共享频谱处理资源的至少2个载波的工作方式所确定，所述的工作方式，由载波所在的频段、频段组合、支持的空口协议、支持的连接类型、支持的链路类型、支持的业务类型中的至少一个确定。例如第一范围通过终端设备支持的空口协议与终端设备支持的业务类型二者来定义，或者通过终端设备支持的链路类型和终端设备支持的不同连接来定义，或者根据运营商支持的频段范围来定义，具体此处不做限定。
需要说明的是，以上所述的在第一范围的至少2个载波间可以共享频谱处理资源是指：终端设备在使用第一范围内的至少2个载波传输数据时，终端设备可以调用小于该至少两个载波的各个载波分别独立用于传输数据时，终端设备所需的最大频谱处理资源的和。
在一种可能的实现方式中，终端设备的能力信息还包括第二指示信息，第二指示信息用于指示第一范围内至少一个载波的最小保证带宽，最小保证带宽表示终端设备为该载波预留的处理能力。
终端设备在第一范围内可以共享的频谱处理资源小于或者等于总的聚合频谱减去该至少一个载波的最小保证带宽之和，例如可以通过如下公式表示：
Figure PCTCN2021093766-appb-000014
其中，K为在第一范围内生效的载波数，信道带宽 (k)为在第一范围内的生效载波k分配的频谱，L为在第一范围内定义了最小保证带宽的载波数量，最小保证带宽 (l)为第一范围内载波l的最小保证带宽。
Figure PCTCN2021093766-appb-000015
表示第一范围内所有具有最小保证带宽的载波的的最小保证带宽的和。
Figure PCTCN2021093766-appb-000016
表示第一范围内所有生效载波可被调度频谱之和。这里的生效载波，指的是能够用于数据传输的载波。
最小保证带宽可以根据终端设备需要监听的信道和/或终端设备需要维持的通信和/或终端设备的实现架构，按照预定义的规则来确定或者由终端设备自主确定。例如，一个载波对应的最小保证带宽可以定义为终端设备维持该一个载波的一个或者多个通信功能的最小带宽。其中，通信功能可以包括以下至少一个：初始接入、接收系统消息、接收寻呼消息、随机接入、上行信令反馈、小包接收或者发送、唤醒信号接收或者发送、下行控制信道监听、测量、移动性、信道质量检测、定时同步、频率跟踪、相位跟踪、波束跟踪和选择等。可以理解的是，还可以包括其他通信功能，例如小区选择和重选，具体此处不做限定。
在一种可能的实现方式中，在3GPP NR系统中，最小保证带宽可以是保证初始接入成功的终端必须支持的带宽。例如，编号为零的控制资源集(control resource set，CORESET)所定义的带宽。在NR所定义的FR1内，最小保证带宽的取值可以包括以下任意一个：5MHz，10MHz，20MHz，40MHz。或者，将NR系统规定的必须支持的初始BWP的带宽的至少一个带宽，定义为最小保证带宽。
在3GPP LTE系统中，最小保证带宽可以是同步信道的带宽，为1.4MHz。其中控制资源 集为下行控制信道PDCCH的频域资源大小。最小保证带宽还可以以实际用于传输数据的资源块为单位定义。例如，在3GPP NR系统中，子载波间隔为30kHz时，最小保证带宽的取值为48资源块RB。在3GPP LTE系统中，子载波间隔为15kHz时，最小保证带宽为6RB。根据终端设备支持的载波所在的频段、所采用的空口协议、连接(Connection)的属性、链路(link)的属性、支持的业务类型等，终端设备支持的载波的最小保证带宽可以有不同的值。如在频段A的载波的最小保证带宽为20MHz，在频段B的载波的最小保证带宽为40MHz。又如，LTE载波的最小保证带宽为1.4MHz，NR的FR1的频段内的载波的最小保证带宽为20MHz，NR FR2的频段内的载波的最小保证带宽为50MHz。或者，Uu link的载波的最小保证带宽为40MHz，侧行链路的载波的最小保证带宽为20MHz。或者，eMBB的载波的最小保证带宽为40MHz，NR V2X的载波的最小保证带宽为40MHz，LTE V2X的载波的最小保证带宽为20MHz，mIoT的载波的最小保证带宽为5MHz，URLLC的载波的最小保证带宽为20MHz等等。
需要说明的是，载波的最小保证带宽可以为零。当载波的最小保证带宽为0时，表示终端设备不会为该载波预留频谱处理资源。
图5为本申请实施例提供的一种终端设备支持的最大聚合频谱的示意图。在图5中，终端设备工作在LTE和NR双连接模式下，终端设备被配置或者激活了一个LTE载波1和一个NR载波2。载波1的最小保证带宽为10MHz，载波2的带宽为40MHz，最大聚合频谱为100MHz，则终端设备可以共享的频谱处理资源为：100MHz-10MHz-40MHz＝50MHz。载波2最大可以调度到90MHz，载波1的调度可以超过10MHz。例如，载波1可以调度到LTE的最大带宽20MHz。
需要说明的是，只有在载波生效时，终端设备才会预留对应的最小保证带宽。
例如，终端设备支持频段A和频段B的载波聚合，终端设备的最大聚合频谱为100MHz，终端设备在频段A下的载波A的最小保证带宽是10MHz，频段B下的载波B的最小保证带宽是20MHz。
当载波A未生效，载波B生效时，终端设备可以用于载波B的总的频谱处理资源为100MHz。
当载波B未生效，载波A生效时，终端设备可以用于载波A的共享的频谱处理资源为100MHz。
当载波A和载波B都生效时，终端设备可以用于同时处理载波A和载波B的最大频谱处理资源为100MHz，其中，终端设备可以共享的频谱处理资源为70MHz(100MHz-10MHz-20MHz),终端设备可以用于处理载波A的最大频谱处理资源为80MHz(100MHz-20MHz)，终端设备可以用于处理载波B的最大频谱处理资源为90MHz(100MHz-10MHz)。
在一种可能的实现方式中，终端设备的能力信息还包括终端设备是否支持调整载波对应的最小保证带宽。
例如，终端设备根据特定的场景，调整载波对应的最小带宽，例如终端设备支持载波A和载波B的载波聚合。载波A的最大信道带宽为100MHz，载波B的最大信道带宽为100MHz，终端设备的最大聚合频谱为100MHz。终端设备可以确定主载波的最小保证带宽为40MHz，副载波的最小保证带宽为0MHz，主载波最多会有100MHz的频谱用于数据传输，副载波则最多有60MHz(100MHz-40MHz)的频谱用于数据传输。则当载波A为终端设备的主载波，载波A的最小保证带宽为40MHz，载波A可以有100MHz用于数据传输，而载波B最多可以有60MHz用于数据传输。如果载波A从主载波更新为副载波，此时载波A的保证带宽为0，则载波A最多可以有60MHz用于数据传输。
终端设备如果支持调整载波对应的最小保证带宽，则可以在应用场景发生改变时，提高资源使用的效率。
需要说明的是，当最小保证带宽为终端设备自主确定时，则终端设备需要向网络设备发送该最小保证带宽，当最小保证带宽为根据预定义的规则来确定时，则终端设备不需要上报该最小保证带宽。
为了降低终端设备和网络设备的调度复杂度以及减少信令负载，终端设备可以设定能力的第一粒度。该第一粒度的单位可以是MHz、Hz或者是GHz等，例如第一粒度为5MHz或者10MHz。或者，第一粒度的单位还可以是其他单位，例如以RB或者RBG为单位。第一粒度可以根据预定义的规则确定，例如规定第一粒度的大小为5MHz。第一粒度还可以根据终端的能力由终端设备确定。可以理解的是，当第一粒度的取值较大时，网络设备的调度复杂度降低，信令负载较低。当第一粒度的取值较小时，终端设备具有更大的灵活度。
在一种可能的实现方式中，终端设备的最大聚合频谱能力用第二粒度的数量来表示。第二粒度为第一粒度的整数倍或与第一粒度相同。例如，终端设备确定第一粒度的大小为10MHz，第二粒度为20MHz，最大聚合频谱能力的信息用2个第二粒度，也就是20MHz的整数倍来定义，则终端设备在确定最大聚合频谱时，最大聚合频谱的取值可以表示为20MHz的整数倍，例如最大聚合频谱为80MHz，或者100MHz。
可以理解的是，终端设备还可以确定共享频谱处理资源的第三粒度。第三粒度为第一粒度的整数倍或与第一粒度相同。例如，第三粒度等于第一粒度，第一粒度为20MHz，则终端设备在第一范围内可以共享的频谱处理资源的第三粒度为20MHz，终端设备在第一范围内支持的最大聚合频谱为100MHz，且终端设备支持两个载波的载波聚合，则终端设备可以支持的频谱处理资源的组合{载波1，载波2}＝{(0，20),(0，40),(0，60),(0，80),(0，100),(20,0)，(20，20)，(20，40)(20,60)(20,80)(40,0)(40,20)，(40,40)，(40,60),(60,0)(60,20),(60,40),(80,0)(80,20),(100,0)}，其中，频谱处理资源的组合的单位为MHz。
在一种可能的实现方式中，终端设备的能力信息还包括第三指示信息。该第三指示信息用于指示终端设备支持在第一范围内的载波内调度多个非连续的资源单元(resource unit,RU)，即终端设备支持一个载波内调度多个非连续的资源单元。该在第一范围内的聚合载波内总的可被调度的多个非连续的资源单元之和，小于或者等于最大聚合频谱。资源单元的大小，可以根据预定义的规则确定。例如资源单元的大小为5MHz。或者，资源单元的大小为采用了相同预编码的频域块的大小，例如资源单元的大小为1个或多个资源块组(resource block group，RBG)。或者可以根据终端设备的能力确定。优选的，资源单元的大小等于第一粒度或第一粒度的整数倍。
在一种可能的实现方式中，第三指示信息用于指示终端设备支持在第一范围内的载波内调度多个非连续的资源单元，该第一范围内的载波内的可被调度的多个非连续的资源单元之和小于或者等于所述最大聚合频谱。
在一种可能的实现方式中，终端设备在第一范围内支持的所有载波中，至少有一个载波包括非连续的资源单元。例如，终端设备在第一范围内支持的所有载波中，每条载波都分别包括非连续的资源单元。或者，终端设备在第一范围内支持的5个载波中，有2个载波分别包括非连续的资源单元。
在一种可能的实现方式中，第三指示信息还包括以下至少一种信息：第一粒度值，第二粒度值，第三粒度值，资源单元的大小。
为了降低终端设备和网路设备的调度复杂度，终端设备确定支持载波内的连续频谱处理。如图6所示，终端设备在第一范围内支持的最大聚合频谱为100MHz。终端设备在频段A激活的载波1对应的带宽为连续的40MHz的频谱，在频段B激活的载波2对应的带宽为连续的60MHz的频谱，载波1对应的带宽和载波2对应的带宽之和等于最大聚合频谱。为了提升系统的性能，充分利用分集增益，终端设备确定支持第一范围内的载波内的多个非连续资源单元的处理。该非连续资源单元的取值可以为最大聚合频谱能力的最小粒度，或者为其他的取值。如图7所示，终端设备支持在第一范围内频段A和频段B的载波聚合，在第一范围内支持的最大聚合频谱为100MHz，资源单元的大小为10MHz，终端设备在频段A中激活的载波1可调度2个频域上不连续的资源单元，4个资源单元总的频谱为40MHz，在频段B中激活的载波2可调度6个频域上不连续的资源单元，6个资源单元总频谱为60MHz。
需要说明的是，本申请提供的实施例中，终端设备支持的载波可以包括连续频谱的载波，也可以包括非连续频谱的载波，在此不做限定。
需要说明的是，终端设备的各个载波的资源单元的大小可以相同，也可以不同。当各个载波的资源单元大小相同时，终端设备的设计实现简单易行。当各个载波的资源单元大小不同时，网络设备可以为不同的类型的终端设备确定不同的资源单元大小，可以增加网络设备调度资源的灵活性。
需要说明的是，本申请提供的实施例所述的载波聚合是广泛意义上的载波聚合，任何同时有两个或者两个以上的载波用于数据传输，就称为这些载波的载波聚合，不论这些载波是否在同一个频段(例如一个是频段A，一个是频段B)，是否是同一个空口协议(例如可以分别是LTE空口或者NR空口)，是否是同一个连接(例如可以分别是两个不同的NR connection)，是否是同一个link(例如分别是Uu link和侧行链路)。
在一种可能的实现方式中，终端设备的能力信息还包括第五指示信息，所述第五指示信息用于指示终端设备在第一范围内的最大聚合层数。
终端设备在第一范围内支持的最大聚合层数可以通过以下公式表示：
Figure PCTCN2021093766-appb-000017
其中，v (j)表示载波j的最大MIMO层数，J表示在第一范围内载波的频段或频段组合的总的聚合载波数。
需要说明的是，本申请实施例中能力信息可以包括最大聚合频谱的具体取值，也可以包括缩放因子，该缩放因子用于确定最大聚合频谱。
例如，当能力信息包括缩放因子时，网络设备在接收到终端设备上报的能力信息后，根据以下公式计算出终端设备的最大聚合频谱：
Figure PCTCN2021093766-appb-000018
其中，BW (j)表示载波j的最大带宽。或者，还可以根据以下公式表示终端设备的最大聚合频谱：
Figure PCTCN2021093766-appb-000019
其中，
Figure PCTCN2021093766-appb-000020
表示载波j对应的最大资源块。
可以理解的是，还可以通过其他公式计算终端设备的最大聚合频谱，具体此处不做限定。
终端设备确定终端设备的能力信息，该能力信息具体包括终端设备在至少一个第一范围内支持的最大聚合频谱的能力信息。终端设备可以确定一个以上的第一频率范围，各第一频率范围内支持的最大聚合频谱能力信息，可以相同，也可以不同。如下表8所示，表示终端设备具有支持3个第一范围的能力，在每个第一范围内各自有定义对应的最大聚合频谱。
表8第一范围和最大聚合频谱的对应示意表
Figure PCTCN2021093766-appb-000021
在步骤202中，终端设备向网络设备发送能力信息。
终端设备在确定了能力信息后，终端设备向网络设备发送该能力信息。
在一种可能的实现方式中，终端设备通过终端设备能力信息上报的方式通过高层信令向网络设备发送能力信息。在终端设备初始接入过程中，终端设备通过能力信息上报的方式，向网络设备发送能力信息，例如，终端设备通过RRC配置信令向网络设备发送该能力信息。
进一步的，终端设备向网络设备发送能力信息时，能力信息的表示方式可以有多种不同的实施方式。例如，能力信息中包含的在第一范围内的最大聚合频谱可以根据以下格式上报：
CA-AggregatedSpectrum::＝ENUMERATED{40MHz,50MHz,150MHz,200MHz,250MHz,300MHz,...}
可选地，最大聚合频谱的上报格式还可以通过资源块来表示，此时，对应不同的子载波间隔，资源块的数目可能不同。例如：对于子载波间隔为30KHz，能力信息中包含的在第一范围内的最大聚合频谱可以根据以下格式上报：
CA-AggregatedSpectrum::＝ENUMERATED{25RB,50RB,65RB,135RB,273RB,…}
对于子载波间隔为15KHz，能力信息中包含的在第一范围内的最大聚合频谱可以根据以下格式上报：
CA-AggregatedSpectrum::＝ENUMERATED{12RB,25RB,50RB,135RB,…}
在一种可能的实现方式中，终端设备还可以通过上报缩放因子的方式来表示能力信息中最大聚合频谱的能力信息，例如：
CA-AggregatedSpectrumFactor::＝ENUMERATED{0.4,0.5,0.6,0.7,0.8,0.9,...}
最大聚合频谱在不同的第一范围内的取值可以不同。可以分别用不同的信元来表示。
可以理解的是，终端设备向网络设备上报能力信息的方式有很多种，具体此处不做限定。
终端设备向网络设备发送能力信息，进一步，还包括，网络设备接收终端设备向网络设备发送的能力信息。
进一步的，在一种可能的实现方式中，该实施例还包括步骤203，在步骤203中，网络设备根据能力信息确定第一范围内的第一频域资源。
网络设备在接收到终端设备上报的能力信息之后，网络设备根据能力信息确定调度的第一范围内的第一频域资源。
具体的，网络设备在确定需要调度的第一频域资源时，确保在第一范围内调度的第一频域资源不超过能力信息指示的终端设备在第一范围内支持的载波聚合的最大聚合频谱。
在一种可能的实现方式中，网络设备配置在第一范围内载波聚合的各个载波的信道带宽，并且网络设备确定在第一范围内所有配置载波的信道带宽的总和不超过能力信息指示的最大聚合频谱。
在一种可能的实现方式中，网络设备激活在第一范围内各个载波的激活BWP的带宽，并且确定在第一范围内所有激活BWP的信道带宽的总和不超过能力信息指示的最大聚合频谱。
在一种可能的实现方式中，网络设备配置在第一范围内的配置载波的BWP的信道带宽，网络设备确定所有配置载波的最大BWP取值的和，不超过能力信息指示的最大聚合频谱。例如，网络设备配置了N个载波，所述N为大于等于1的正整数，每个载波配置了一个或者多个BWP，则
Figure PCTCN2021093766-appb-000022
不超过能力信息指示的最大聚合频谱。
在一种可能的实现方式中，网络设备能力信息和生效的载波确定第一频率范围。例如，网络设备从终端设备上报的能力信息中获知终端设备在第一范围内支持的最大聚合频谱是100MHz，在运营商1的网络下，运营商在第一范围内的频段A分配到的频谱为40MHz；在频段B分配到的频谱为60MHz。网络设备在运营商1的网络下，给终端设备配置了两个载波。载波1在频段A中，载波1的最大的BWP为40MHz，载波2在频段B中，载波2的最大的BWP为60MHz。若在运营商2的网络下，运营商2在第一范围内的频段A分配到的频谱为80MHz，在频段B分配到的频谱为40MHz。网络设备在运营商2的网络下，给终端设备配置了两个载波，载波1在频段A中，载波1的最大BWP为60MHz，载波2在频段B下，载波2的最大BWP为40MHz。即不论是在运营商1或者是运营商2的网络下，网络设备给终端设备配置的载波的最大BWP的和不超过终端设备上报的能力信息中指示的最大聚合频谱。
在一种可能的实现方式中，网络设备还根据能力信息中的第一指示信息确定需要调度的第一范围的大小，从而确定需要配置的载波。
例如，网络设备根据第一指示信息确定第一范围为Uu link和sidelink,在第一范围内 支持的最大聚合频谱为100MHz。若网络设备没有为终端设备配置sidelink，则网络设备为终端设备配置载波1，载波1的带宽小于等于100MHz。若网络设备同时为终端设备配置了Uu link和Sidelink，则在Uu link的载波1的带宽小于等于60MHz，sidelink的载波2的带宽小于等于40MHz。Uu link的载波1和Sidelink的载波2总的配置的带宽不超过100MHz。
在一种可能的实现方式中，网络设备还根据能力信息中的第二指示信息确定在第一范围内的第一频域资源。
具体的，网络设备根据能力信息中的第二指示信息确定第一范围内每个载波的最小保证带宽。网络设备在给终端设备配置第一频域资源时，确定可被载波共享的频域资源不超过最大聚合频谱减去生效载波的最小保证带宽之和。
图8为本申请实施例提供的另一种终端设备支持的最大聚合频谱的示意图。在图8中，网络设备根据终端设备上报的能力信息，获知频段A和频段B可以共享频域资源，在只有频段A的载波生效的情况下，网络设备可以给频段A的生效载波配置的带宽小于或者等于最大聚合频谱。在频段A载波和频段B载波同时生效的情况下，网络设备可以给频段A载波配置的带宽小于或者等于最大聚合频谱减去频段B载波的最小保证带宽，网络设备给频段B载波配置的带宽小于或者等于最大聚合频谱减去频段A载波的最小保证带宽。
图9为本申请实施例提供的另一种终端设备支持的最大聚合频谱的示意图。在图9中，网络设备根据终端设备上报的能力信息，获知Uulink和Sidelink可以共享频域资源，在t1到t2时间段下，只有Uulink载波生效的情况下，网络设备可以给Uulink生效载波配置的带宽小于或者等于最大聚合频谱。在t2到t3时间段下，Uulink载波和Sidelink载波同时生效的情况下，网络设备可以给Uulink载波配置的带宽小于或者等于最大聚合频谱减去Sidelink载波的最小保证带宽，网络设备给Sidelink载波配置的带宽小于或者等于最大聚合频谱减去Uulink载波的最小保证带宽。在t2到t3时间段下，只有Sidelink载波生效的情况下，网络设备可以给Sidelink生效载波配置的带宽小于或者等于最大聚合频谱。其中，如图9所示，Uulink的最小保证带宽为40MHz，Sidelink的最小保证带宽为20MHz，最大聚合频谱为100MHz。图9所示的t1、t2及t3为不同的三个时间点。Sidelink和Uulink可以属于同一个频段，也可以属于不同的频段，具体此处不做限定。
图9所示的实现方式，其中一种具体的应用场景为在终端设备初始接入网络阶段，终端设备可以用于Uu link数据传输的载波聚合后的总的带宽小于或者等于最大聚合频谱，例如最大聚合频谱为100MHz。在接入网络之后，终端设备激活sidelink，sidelink的最小保证带宽为40MHz，则用于Uu link的数据传输的载波聚合后的总带宽小于等于60MHz。
在一种可能的实现方式中，网络设备还根据能力信息中的第三指示信息确定在第一范围内的第一频域资源。
具体的，网络设备根据第三指示信息确定在第一范围内可以给终端设备的载波配置多个非连续的资源单元。
在一种可能的实现方式中，网络设备还根据能力信息中的第五指示信息确定在第一范围内的第一频域资源。
具体的，网络设备根据第五指示信息确定在第一范围内终端设备支持的MIMO总层数，并配置各个载波的MIMO总层数，使得所有配置载波上的MIMO总层数之和，不超过最大聚合层数。
可以理解的是，在实际应用过程中，网络设备还可以根据能力信息中更多的指示信息配置第一频域资源，具体此处不做限定。
网络设备在确定了第一频域资源后，根据第一频域资源生成第一调度信息。
进一步的，在一种可能的实现方式中，该实施例还包括步骤204，在步骤204中，网络设备向终端设备发送第一调度信息。
网络设备生成了第一调度信息之后，网络设备向终端设备发送第一调度信息。
在一种可能的实现方式中，网络设备可以通过RRC信令、MAC层信令或者物理层信令中的一个或者多个来承载第一调度信息，第一调度信息可以在一个信令中发送给终端设备，也可以在多个信令中发送给终端设备，具体此处不做限定。
例如，网络设备配置载波1的最大BWP为60MHz，网络设备配置载波2的最大BWP为40MHz，网络设备通过RRC信令承载这两条配置信息并向终端设备发送。
例如，网络设备通过RRC信令配置载波1有两个BWP，BWP1的带宽为80MHz，BWP2的带宽为60MHz，网络设备配置载波2有两个BWP，BWP3的带宽为20MHz，BWP4的带宽为40MHz，网络设备在T1时间，通过物理层信令或者MAC信令承载激活的信令，激活BWP1和BWP3，在T2时间，通过物理层信令或者MAC信令承载激活的信令，激活BWP2和BWP4。
可以理解的是，在实际应用过程中，网络设备还可以通过其他方式发送第一调度信息，具体此处不做限定。
网络设备向终端设备发送第一调度信息，进一步的，还包括，终端设备接收第一调度信息。
进一步的，在一种可能的实现方式中，该实施例还包括步骤205，在步骤205中，终端设备根据第一调度信息确定频谱处理资源。
终端设备接收到第一调度信息之后，根据第一调度信息确定网络设备调度的第一频域资源，该第一频域资源用于第一设备进行数据传输，该第一频域资源小于或者等于最大聚合频谱。在确定了第一频域资源之后，终端设备根据第一频域资源确定终端设备的频谱处理资源，该频谱处理资源包括终端设备接收和/或发送第一频域资源上所承载的数据时使用的终端设备的处理资源。
在一种可能的实现方式中，终端设备根据第一频域资源确定第一范围内生效的载波，并根据生效的载波配置对应的频谱处理资源。例如，在第一频域资源中指示网络设备激活了2个载波，分别为载波1和载波2，载波1和载波2的带宽分别为20MHz和40MHz，则终端设备分别给载波1和载波2分配20MHz和40MHz的频谱处理资源。
例如，在第一频域资源中，网络设备给终端设备配置两个载波，载波1在频段A，最大BWP为40MHz，载波2在频段B，最大BWP为60MHz，则终端设备给载波1分配40MHz的频谱处理资源，给载波2分配60MHz的频谱处理资源。
在一种可能的实现方式中，当终端设备根据第一频域资源确定第一范围内生效的载波包括了非连续的资源单元时，则终端设备根据该生效的非连续的载波配置对应的频谱处理资源。例如，在第一频域资源中，网络设备给终端设备配置两个载波，载波1包括了连续的资源单元，载波2包括了非连续的资源单元，则终端设备给载波1分配对应的一部分频谱处理资源，给载波2中非连续的资源单元分别分配对应的频谱处理资源。
在一种可能的实现方式中，终端设备在确定了第一频域资源之后，获知第一频域资源指 示在第一范围内同时接受和/或发送的频谱超过了终端设备在第一范围内支持的最大聚合频谱，则终端设备确定第一调度信息出错，终端设备可以丢弃该第一调度信息，或者向网络设备发送第一调度信息出错的提示，可以理解的是，终端设备还可以根据自己支持的最大聚合频谱，不接收和/或不发送第一频域资源中超过最大聚合频谱那部分的频谱对应的数据，具体此处不做限定。
本申请实施例中，终端设备支持的最大聚合频谱小于第一范围内频段或者频段组合内每个载波对应的最大带宽的和，减少了终端设备需要设计的频谱处理能力，有利于终端设备成本的降低。
二、第一设备上报能力更新。
本实施例中，以第一设备为终端设备、第二设备为网络设备为例进行描述。本申请实施例中，当第一设备上报能力信息之后，对应的能力信息发生了变化。当终端设备的能力信息变化的原因有多种情况，可以是终端设备在不同的空口协议下发生的变化，也可能是应用场景发生变化导致的能力信息变化。
能力信息的更新包括实施例一中所述的能力信息中的一个或多个信息的更新，如最大聚合频谱的更新，第一范围的更新，第三指示信息的更新等。这里以终端设备更新第一范围为例进行说明，终端设备上报的能力信息中的其他信息更新的流程类似，不再一一表述。
如图3所示，为本申请实施例另一能力信息上报方法的流程示意图。
在步骤301中，终端设备确定能力信息。
在步骤302中，终端设备向网络设备发送能力信息。
在步骤303中，网络设备根据能力信息确定在第一范围内的第一频域资源。
在步骤304中，网络设备向终端设备发送第一调度信息。
在步骤305中，终端设备根据第一调度信息确定频谱处理资源。
本实施例中的步骤301至步骤305与上述图2实施例中的步骤201至步骤205类似，具体此处不再赘述。
在步骤306中，终端设备向网络设备发送第四指示信息。
当能力信息发生改变时，终端设备向网络设备发送更新后的能力信息。终端设备可以更新全部或部分能力信息，例如当第一范围发生改变时，终端设备会向网络设备发送第四指示信息，该第四指示信息指示终端设备的能力信息的更新。
第一范围由可以共享频谱处理资源的至少2个载波的工作方式所确定，所述的工作方式，由载波所在的频段、频段组合、支持的空口协议、支持的连接类型、支持的链路类型、支持的业务类型中的至少一个确定。例如，第一范围通过终端设备支持的空口协议与终端设备支持的业务类型来定义，或者通过终端设备支持的链路类型和终端设备支持的不同连接来定义，或者根据运营商支持的频段范围来定义。当工作方式发生改变时，第一范围会发生变化。例如，当第一范围是根据终端设备支持的空口接入协议定义的，如果终端设备支持非独立(non-standalone，NSA)和独立(standalone，SA)网络，NSA网络下终端设备支持LTE和NR两个空口协议，SA网络下终端设备支持NR网络。则当终端设备从NSA网络接入到SA网络后，第一范围的确定从LTE空口和NR空口改为只有NR空口，因此终端设备确定第一范围发生变化。或者当第一范围为根据终端设备支持的频段集合定义，如果终端设备有新增的可以支持的频段和/或频段组合，则终端设备确定第一范围发生变化。或者，终端设备支持的链路类型 发生了变化，例如从仅支持Uu link到既支持Uu link，也支持Sidelink，则终端设备确定第一范围发生变化。
可以理解的是，在实际应用过程中，还可以有更多的第一范围发生变化的情况，具体此处不做限定。
例如，当第一范围是根据终端设备支持的空口接入协议定义的，如果终端设备从NSA(Non-standalone)到SA(standalone)网络，NSA网络终端支持LTE和NR两个空口协议，SA网络终端设备支持NR网络，则第一范围从LTE空口和NR空口改为只有NR空口，因此终端设备需要更新能力信息，网络设备需要重新调度资源来进行对应的匹配。或者当第一范围是根据终端设备支持的频段集合定义的，如有新增的可以支持的频段和/或频段组合，则第一范围可能会发生变化，因此终端设备需要更新能力信息，网络设备需要重新调度资源来进行对应的匹配。又或者，当终端设备支持的链路类型发生了变化，从仅支持Uu link到既支持Uu link，也支持Sidelink，导致了第一范围发生变化，则终端设备需要更新能力信息，网络设备需要重新调度资源来进行对应的匹配。
在一种可能的实现方式中，终端设备可以通过去注册网络(de-registration)和/或去附着网络(detach)的方式向网络设备更新能力信息，可以理解的是，还可以通过其他方式向网络设备更新能力信息，例如通过注册网络(registration)和/或附着网络(attach)的方式更新能力信息，终端设备通过发送辅助信息的方式更新能力信息等，具体此处不做限定。
在步骤307中，网络设备根据第四指示信息确定第二频域资源。
网络设备在接收到终端设备发送的第四指示信息之后，网络设备根据第四指示信息确定需要更新的第一范围，进而根据更新后的第一范围和终端设备的能力信息确定第二频域资源，该第二频域资源用于网络设备和终端设备之间进行数据传输。
本实施例中，网络设备根据更新后的第一范围和终端设备的能力信息确定第二频域资源的方法和图2实施例中步骤203中网络设备根据第一范围和终端设备的能力信息确定第一频率资源的方法类似，具体此处不再赘述。
在步骤308中，网络设备向终端设备发送第二调度信息。
在步骤309中，终端设备根据第二调度信息确定第二频谱处理资源。
本实施例中的步骤308和步骤309与上述图2实施例中的步骤204和步骤205类似，具体此处不再赘述。
本实施例中，终端设备可以明确的在第四指示信息中携带已经更新的第一范围的信息，也可以不在第四指示信息中携带已经更新的第一范围的信息，而只携带指示更新的消息。网络设备在接收到终端设备发送的指示更新的消息之后，会向终端设备发送一个查询消息，该查询消息用于查询终端设备的更新的能力信息，或者，终端设备也可以通过终端设备辅助信息(UE assisted information)的方式向网络设备发送更新后的第一范围的信息，具体此处不做限定。
本申请实施例中，终端设备向网络设备发送终端设备在第一范围内支持的最大聚合频谱，且该最大聚合频谱小于终端设备在第一范围内支持的所有聚合载波的最大带宽的和，使得在设计终端设备支持的能力时，避免了终端设备需要按照支持的所有聚合载波的最大带宽来设计对应的能力。而第一设备支持的能力越大时，需要对应的成本就越高。因此通过本申请实施例提供的能力信息上报方法进行上报，可以在第一设备设计的阶段就避免设计过多的能力， 有利于第一设备的成本的降低。
如图4所示，为本申请实施例另一能力信息上报方法的流程示意图。
需要说明的是，本实施例中，当第一终端设备在向网络设备上报能力信息时，第一终端设备对应为第一设备，网络设备对应为第二设备。当第一终端设备接收第二终端设备发送的能力信息时，则第一终端设备对应为第二设备，第二终端设备对应为第一设备。
在步骤401中，第一终端设备确定能力信息。
在步骤402中，第一终端设备向网络设备发送能力信息。
在步骤403中，网络设备根据第一能力信息确定在第一范围内的第一频域资源。
在步骤404中，网络设备向第一终端设备发送第一调度信息。
在步骤405中，第一终端设备根据第一调度信息确定频谱处理资源。
本实施例中的步骤401至步骤405与前述图2中的步骤201至步骤205类似，具体此处不再赘述。
在步骤406中，第二终端设备向第一终端设备发送目标能力信息。
在特殊的场景模式下，第二终端设备需要向第一终端设备发送第二终端设备的目标能力信息，该目标能力信息用于第一终端设备和第二终端设备可以进行直接通信。
在一种可能的实现方式中，在空闲(idle)或者非激活(inactive)模式下，第二终端设备和第一终端设备通过PC5接口，利用模式2(mode2)资源两个终端设备之间可以直接通信，但是在这种情况下，第一终端设备已经在和网络设备进行通信，因此，需要第二终端设备向第一终端设备发送第二终端设备的目标能力信息，第一终端设备可以根据第二终端设备的目标能力信息的指示，避开接收网络设备消息和/或向网络设备发送消息的子帧，和第二终端设备进行通信。
可以理解的是，还有更多的场景模式下，第二终端设备向第一终端设备发送目标能力信息，例如在V2X场景下，具体此处不再赘述。
本实施例中，第二终端设备确定目标能力信息的方法和步骤401中第一终端设备确定能力信息的方法类似，具体此处不再赘述。
在步骤407中，第一终端设备根据目标能力信息确定目标频谱处理资源。
第一终端设备在接收到第二终端设备发送的目标能力信息之后，第一终端设备根据目标能力信息确定可以用于和第二终端设备进行通信的目标频谱处理资源。
第一终端设备在确定了目标频谱处理资源之后，第一终端设备更新了第一终端设备的能力信息，并且生成第四指示信息，第四指示信息指示第一终端设备的能力信息发生了变化。
在步骤408中，第一终端设备向网络设备发送第四指示信息。
在步骤409中，网络设备根据第四指示信息确定第二频域资源。
在步骤410中，网络设备向第一终端设备发送第二调度信息。
本实施例中，步骤408至410与图3所述实施例中的步骤306至步骤308类似，具体此处不再赘述。
在步骤411中，第一终端设备根据第二调度信息确定第二频谱处理资源。
第一终端设备接收到第二调度信息之后，根据第二调度信息确定网络设备配置的第二频域资源，在确定了第二频域资源之后，第一终端设备根据第二频域资源确定第一终端设备的第二频谱处理资源。
在一种可能的实现方式中，第一终端设备根据第二频域资源确定更新后的第一范围内生效的载波，并根据生效的载波配置对应的第二频谱处理资源。例如，第二频域资源指示网络设备激活了2个载波，分别为载波1和载波2，载波1和载波2的带宽分别为20MHz和40MHz，则终端设备分别给载波1和载波2分配20MHz和40MHz的频谱处理资源。
例如，在第二频域资源中，网络设备给第一终端设备配置两个载波，载波1在频段A，最大BWP为40MHz，载波2在频段B，最大BWP为60MHz，则第一终端设备给载波1分配40MHz的频谱处理资源，给载波2分配60MHz的频谱处理资源。
需要说明的是，第一终端设备和第二终端设备通信使用的目标频谱处理资源和第一终端设备与网络设备通信的第二频谱处理资源的和不超过第一终端设备总的频谱处理资源。
在一种可能的实现方式中，第一终端设备在确定了第二频域资源之后，获知第二频域资源指示在更新后的第一范围内同时接收和/或发送的频谱超过了第一终端设备在更新后的第一范围内支持的最大聚合频谱，则第一终端设备确定第二调度信息出错，第一终端设备可以丢弃该第二调度信息，或者向网络设备发送第二调度信息出错的提示，可以理解的是，第一终端设备还可以根据自己支持的最大聚合频谱，不接收和/或不发送第一频域资源中超过最大聚合频谱那部分的频谱对应的数据，具体此处不做限定。
本实施例中，第一终端设备可以明确的在第四指示信息中携带已经更新的第一范围的信息，也可以不在第四指示信息中携带已经更新的第一范围的信息，而只携带指示更新的消息，网络设备在接收到第一终端设备发送的指示更新的消息之后，会向第一终端设备发送一个查询消息，该查询消息用于查询第一终端设备的更新的能力信息，或者，第一终端设备也可以通过第一终端设备辅助信息(UE assisted information)的方式向网络设备发送更新后的第一范围的信息，具体此处不做限定。
本实施例中，第一终端设备可以在不同的载波之间共享第一终端设备的频谱处理资源，节省了第一终端设备的成本。
