具体实施方式
图1是本申请应用的通信系统1000的架构示意图。如图1所示，该通信系统包括无线接入网100和核心网200，可选的，通信系统1000还可以包括互联网300。其中，无线接 入网100可以包括至少一个无线接入网设备(如图1中的110a和110b)，还可以包括至少一个终端(如图1中的120a-120j)。终端通过无线的方式与无线接入网设备相连，无线接入网设备通过无线或有线方式与核心网连接。核心网设备与无线接入网设备可以是独立的不同的物理设备，也可以是将核心网设备的功能与无线接入网设备的逻辑功能集成在同一个物理设备上，还可以是一个物理设备上集成了部分核心网设备的功能和部分的无线接入网设备的功能。终端和终端之间以及无线接入网设备和无线接入网设备之间可以通过有线或无线的方式相互连接。图1只是示意图，该通信系统中还可以包括其它网络设备，如还可以包括无线中继设备和无线回传设备等，在图1中未画出。
无线接入网设备可以是基站(base station)、演进型基站(evolved NodeB，eNodeB)、发送接收点(transmission reception point，TRP)、第五代(5th generation，5G)移动通信系统中的下一代基站(next generation NodeB，gNB)、第六代(6th generation，6G)移动通信系统中的下一代基站、未来移动通信系统中的基站或无线保真(wireless fidelity，WiFi)系统中的接入节点等；也可以是完成基站部分功能的模块或单元，例如，可以是集中式单元(central unit，CU)，也可以是分布式单元(distributed unit，DU)。这里的CU完成基站的无线资源控制(radio resource control，RRC)协议和分组数据汇聚层协议(packet data convergence protocol，PDCP)的功能，还可以完成业务数据适配协议(service data adaptation protocol，SDAP)的功能；DU完成基站的无线链路控制(radio link control，RLC)层和介质访问控制(medium access control，MAC)层的功能，还可以完成部分物理(physical，PHY)层或全部物理层的功能，有关上述各个协议层的具体描述，可以参考第三代合作伙伴计划(3rd generation partnership project，3GPP)的相关技术规范。无线接入网设备可以是宏基站(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等。本申请的实施例对无线接入网设备所采用的具体技术和具体设备形态不做限定。为了便于描述，下文以基站作为无线接入网设备的例子进行描述。
终端也可以称为终端设备、用户设备(user equipment，UE)、移动台、移动终端等。终端可以广泛应用于各种场景，例如，设备到设备(device-to-device，D2D)、车物(vehicle to everything，V2X)通信、机器类通信(machine-type communication，MTC)、物联网(internet of things，IOT)、虚拟现实、增强现实、工业控制、自动驾驶、远程医疗、智能电网、智能家具、智能办公、智能穿戴、智能交通、智慧城市等。终端可以是手机、平板电脑、带无线收发功能的电脑、可穿戴设备、车辆、无人机、直升机、飞机、轮船、机器人、机械臂、智能家居设备等。本申请的实施例对终端所采用的具体技术和具体设备形态不做限定。

基站和终端的角色可以是相对的，例如，图1中的直升机或无人机120i可以被配置成移动基站，对于那些通过120i接入到无线接入网100的终端120j来说，终端120i是基站；但对于基站110a来说，120i是终端，即110a与120i之间是通过无线空口协议进行通信的。当然，110a与120i之间也可以是通过基站与基站之间的接口协议进行通信的，此时，相对于110a来说，120i也是基站。因此，基站和终端都可以统一称为通信装置，图1中的110a和110b可以称为具有基站功能的通信装置，图1中的120a-120j可以称为具有终端功能的通信装置。
基站和终端之间、基站和基站之间、终端和终端之间可以通过授权频谱进行通信，也可以通过免授权频谱进行通信，也可以同时通过授权频谱和免授权频谱进行通信；可以通过6千兆赫(gigahertz，GHz)以下的频谱进行通信，也可以通过6GHz以上的频谱进行通信，还可以同时使用6GHz以下的频谱和6GHz以上的频谱进行通信。本申请的实施例对无线通信所使用的频谱资源不做限定。

在本申请中，基站向终端发送下行信号或下行信息，下行信息承载在下行信道上；终端向基站发送上行信号或上行信息，上行信息承载在上行信道上。终端为了与基站进行通信，需要与基站控制的小区建立无线连接。与终端建立了无线连接的小区称为该终端的服务小区。当终端与该服务小区进行通信的时候，还会受到来自邻区的信号的干扰。
可以理解的是，本申请的实施例中，物理下行共享信道(physical downlink shared channel，PDSCH)、物理下行控制信道(physical downlink control channel，PDCCH)、物理上行共享信道(physical uplink shared channel，PUSCH)和物理上行控制信道(physical uplink control channel，PUCCH)只是作为下行数据信道、下行控制信道、上行数据信道和上行控制信道的一种举例，在不同的系统和不同的场景中，数据信道和控制信道可能有不同的名称，本申请的实施例对此并不做限定。
为了便于理解，首先对本申请涉及的通信技术进行说明，可以理解的是，该通信技术也作为本申请内容的一部分。
一、载波聚合(carrier aggregation，CA)
载波聚合是将至少2个载波单元(component carrier，CC)聚合在一起，以支持更大传输带宽的技术。为了高效地利用零碎的频谱，载波聚合支持不同载波单元之间的聚合，比如，相同或不同带宽的载波单元的聚合，或者，同一频带内，邻接或非邻接载波单元间的聚合，或者，不同频带内载波单元间的聚合等。
二、双连接(dual connectivities，DC)
终端同时与两个基站保持连接，并接受服务，称之为双连接架构。在终端保持连接的两个基站中，一个基站称为主站(master node，MN)，另一个基站称为辅站(secondary node，SN)。可选的，主站的功能要强于辅站。例如，终端可先与主站建立连接，在满足一定条件，例如，终端的吞吐量增加时，再与辅站建立连接。其中，主站为终端提供空口资源的小区组，称为主小区组(master cell group，MCG)，辅站为终端提供空口资源的小区组，称为辅小区组(secondary cell group，SCG)。主小区组中可包括至少一个小区，该至少一个小区中包括主小区和辅小区，主小区的数量为一个。辅小区组中包括至少一个小区，该至少一个小区中包括主辅小区和辅小区，主辅小区的数量为一个。
应当指出，在本申请的描述中，小区组包括至少一个小区，还可称为主小区组关联至少一个小区。例如，主小区组包括主小区，可称为主小区组关联主小区。一个小区可以关联至少一个载波(carrier)，或称为一个小区对应至少一个载波。在后续描述中，以一个小区对应一个载波，载波还可称为CC为例说明。
在本申请中，双连接的终端可实现不同载波间的聚合。举例来说，终端可利用主站对 应的主小区组中包括的至少一个小区对应的载波，与辅站对应的辅小区组中包括的至少一个小区对应的载波，同时与基站进行通信。例如，同时接收来自基站的PDSCH，和同时向基站发送PUSCH等。上述可称为主小区组中小区对应的载波，与辅小区组对应小区的载波的聚合。或者，还可实现，主小区组中至少两个小区对应的载波间的聚合，或者，辅小区组中至少两个小区对应的载波间的聚合等。
三、多传输接收点(multiple transmission reception point,multi-TRP)
multi-TRP传输允许一个服务小区通过两个TRP调度一个终端，通过多站协作传输，可以解决小区间干扰问题并提升小区边缘用户吞吐量，改善小区边缘的频谱效率。也就是说，在multi-TRP场景下，终端可采用多个TRP与基站进行通信。在3GPP中定义TRP是包括一个或多个天线阵子的可供网络使用的天线阵列，位于特定区域的特定地理位置。一个基站产生的信号可通过至少两个不同位置的TRP进行传输。一个服务小区对应于基站的一个载波，该载波信号可以通过至少两个TRP向服务小区的一个终端进行传输，即一个服务小区通过至少两个TRP调度一个终端。
在非理想回传场景下，两个TRP的通信时延是毫秒级别，与NR中毫秒级别的调度相比无法忽略，为了保证多站协作的性能，需要每个TRP各自发送下行控制信息(downlink control information，DCI)，调度各自的PDSCH，进行数据传输。这种方式通常称为基于多下行控制信息的多传输接收点(multi-DCI based multi-TRP)传输方案。
在当前的方案中，终端可通过RRC中的信元(例如FeatureSetDownlinkPerCC)，上报其在对应CC上是否支持multi-TRP。如果某个CC支持multi-TRP，则终端在该CC可与多个TRP传输数据。
四、多连接(multiple connectivities，MC)
MC允许一个终端同时使用两个以上不同的调度实体调度无线资源，从而支持多个频段、多个基站或多种无线接入技术(radio access technology，RAT)之间的聚合。MC可以突破CA中多个DU需要共站址部署或需要理想回程的限制，也可以突破DC中最多只能支持两个调度实体的限制，从而进一步提高网络吞吐量、减少移动终端进行服务小区切换时的中断时间、实现网络的灵活部署。例如，在MC中，支持NR FR1(800MHz的CC)+NR FR1(3.5GHz的CC)+NR FR2(NR FR2频段的任一个CC)之间的聚合，或者支持NR FR1(NR FR1频段的任一个CC)+NR FR2(28GHz的CC)+NR FR2(大于52GHz的CC)之间的聚合，或者支持LTE+NR FR1+NR FR2之间CC的聚合。关于FR1和FR2的具体说明，可参见后续内容。
五、终端基带处理能力
终端的通信器件一般包括基带处理器、射频收发器、射频前端和天线等核心部分。
在一种基带处理的架构中，其主要包括微控制单元(micro controller unit，MCU)和数字信号处理器(digital signal processor，DSP)。MCU主要用于运行基带协议栈代码，例如媒体接入控制(media access control，MAC)层调度算法和无线资源控制(radio resource control，RRC)、服务数据适配协议(service data adaptation protocol，SDAP)、分组数据汇聚层协议(packet data convergence protocol，PDCP)、无线链路控制(radio link control，RLC)、MAC、和物理(physical，PHY)层等协议流程实现；DSP主要用于实现PHY层核心算法，例如编解码、傅里叶变换/逆傅里叶变换、循环冗余校验、信道估计等。
其中，终端的基带处理器的总能力是有限的。基带处理器的总能力有多种含义。例如， 基站处理器的总能力可包括以下至少一项：在一个时隙上，在所有载波或频段或小区或小区组或带宽部分(bandwidth part，BWP)上，同时传输PDSCH或PUSCH的数目；同时传输PDSCH或PUSCH的层数；同时处理的控制资源集(control resource set，CORESET)的总数目；DCI盲检次数；同时处理各类信道状态信息-参考信号(channel state informaiton-reference single,CSI-RS)的总数目；同时处理的用于波束管理的CSI-RS的总数目；同时激活的(transmission configuration indication，TCI)状态的总数目；同时处理的跟踪参考信号(tracking reference signal，TRS)的总数目；同时处理探测参考信号(sounding reference signal，SRS)的总数目；同时发送的PUCCH的总数目；同时传输的SRS的总数目；同时传输的肯定性确认(acknowledge，ACK)/否定性确认(negative acknowledge，NACK)的总数目；同时反馈信道状态信息(channel state information，CSI)的总数目；同时支持的混合自动重传请求(hybrid automatic repeat request，HARQ)的进程数。
六、带宽部分(bandwidth part，BWP)
BWP是载波上一组连续的频域资源。例如，BWP是载波上一组连续的资源块(resource block，RB)、或载波上一组连续的子载波，或载波上一组连续的资源块组(resource block group，RBG)等。举例而言，在一个小区中，对于一个终端，最多可以为该终端配置4个BWP。在任一时刻，在一小区中，能激活一个BWP，终端和基站在激活的BWP上进行数据的收发。
例如，在载波带宽内，针对一个终端可配置一个BWP，所述BWP的带宽小于或等于终端能力带宽，终端能力带宽小于或等于载波带宽。或者，在载波带宽内，针对一个终端可配置两个BWP，分别称为BWP1和BWP2，且BWP1和BWP2的带宽可重叠，或者BWP1和BWP2的带宽不重叠。
七、控制资源池(CORESET POOL)
BWP是终端的工作带宽，CORESET是终端在BWP中传输控制信令的时频资源，一个BWP可包括多个CORESET。在multi-TRP的场景下，存在CORESET POOL的概念，每个CORESET POOL认为是终端在该BWP上与一个TRP传输控制信令的时频资源，每个BWP中包括至少一个CORESET POOL，每个CORESET POOL中包括至少一个CORESET。
八、时间单元
时间单元的单位可以为无线帧(radio frame)、子帧(subframe)、时隙(slot)、微时隙(mini-slot)和符号(symbol)等单位。例如，一种具体实现中，一个时间单元可包括2个时隙等。一个无线帧可以包括一个或多个子帧，一个子帧可以包括一个或者多个时隙。针对不同的子载波间隔可以有不同的时隙长度。比如子载波间隔为15kHz时，一个时隙可以为1毫秒(ms)；子载波间隔为30kHz时，一个时隙可以为0.5ms。一个时隙可以包括一个或多个符号。比如正常循环前缀(cyclic prefix,CP)下一个时隙可以包括14个时域符号，扩展CP下一个时隙可以包括12个时域符号。时域符号可以简称为符号。时域符号可以是正交频分复用(orthogonal frequency division multiplexing，OFDM)符号，也可以是基于离散傅立叶变换扩展的正交频分复用(discrete fourier transform spread orthogonal frequency division multiplexing，DFT-s-OFDM)符号，本申请实施例中可以以时域符号是OFDM符号为例进行说明。微时隙,又称为迷你时隙，可以是比时隙更小的单位，一个微时隙可以包括一个或多个符号。比如一个微时隙可以包括2个符号，4个符号或7个符号等。一个时 隙可以包括一个或多个微时隙。
在一种方案中，基站通过RRC信令，实现上述CA、DC、MC或multi-TRP等的配置或重配置等。以CA为例，基站可通过向终端发送RRC信令，配置CC1与CC2的聚合。终端在接收到上述RRC信令时，利用CC1和CC2同时与基站传输数据。例如，利用CC1和CC2可同时接收来自基站的PDSCH，这样终端可同时接收2个PDSCH。由于终端的基带处理能力是有限的，比如终端只能同时接收来自基站的5个PDSCH。如何根据网络的状态，实时的切换终端的基带处理能力中的资源，从而实现终端的基带处理能力的高效利用，是本申请待解决的技术问题。例如，当网络的状态变化时，例如CC2对应的频段拥塞或者CC2对应的频段的信道质量较差时，可以将CC2中的接收1个PDSCH的配置，更改为不接收PDSCH的配置；将CC1中的接收1个PDSCH的配置，更改为接收2个PDSCH的配置，从而实现终端基带处理能力的高效利用。
本申请提供一种通信方法，包括：根据终端上报的基带处理能力，预先为终端配置至少一种配置；后续实时的根据网络状态，向终端指示不同的配置；终端利用所指示的配置，与基站通信。采用上述方案，可根据网络状态的不同，动态对终端基带处理能力对应的不同的配置进行切换，从而灵活和高效利用终端的基带处理能力，实现终端基带处理能力的高效利用，提高终端的上下行吞吐和用户体验。
如图2所示，提供一种通信方法的流程，至少包括：
步骤200：终端向基站上报终端能力。相应的，基站接收来自终端上报的终端能力，该终端能力可以是一个频段组合的能力。一个频段组合包括一个或多个频段或载波，对应终端的至少一个小区或小区组或BWP。该步骤200是可选的。
示例的，所述终端能力中包括所述终端的以下能力中的至少一项：
PDSCH的能力；例如，接收PDSCH的最大数目；
PUSCH的能力；例如，发送PUSCH的最大数目；
在CORESET POOL上盲检DCI的能力；例如，盲检DCI的CORESET POOL的最大数目；
空分复用的传输能力；例如，空分复用的最大传输层数；
跟踪的TCI状态的能力；例如，跟踪的TCI状态的最大数目；
或HARQ进程的能力；例如，HARQ进程的最大数目等。
在本申请中，关于终端上报终端能力的方式，至少包括：以终端能力包括PDSCH能力为例，则针对一个频段组合，终端可以向基站上报多组能力，每组能力对应于该载波上同时接收PDSCH的最大数目。举例来说，一个频段组合包括3个载波，则终端可以向基站上报3组能力，每组能力中包括该终端在对应载波接收PDSCH的能力。例如，对于载波1，终端上报的一组终端能力，其包括：终端在载波1接收PDSCH的最大数目N1；对于载波2，终端上报一组终端能力，其包括：终端在载波2接收PDSCH的最大数目N2；对于载波3，终端上报一组终端能力，其包括：终端在载波3接收PDSCH的最大数目N3。或者，对于一个频段组合，终端上报多种能力，一组能力中包括多个能力参数，每个能力参数中包括对应频段上传输PDSCH的最大数目。例如，一个频段组合中包括两个载波，分别称为载波1和载波2，则终端上报两组能力，分别为{2，0}和{1，1}。上述每组能力中包括两个能力参数，其每个能力参数代表在对应的载波上传输PDSCH的最大数目。例如，{2，0}具体表示终端仅支持在载波1上传输，对于载波2不支持传输，即在载波1上， 终端最多支持同时传输2个PDSCH，在载波2上，终端不支持传输PDSCH。{1，1}具体表示终端支持载波1和载波2的聚合，但在载波1和载波2上同时只支持传输1个PDSCH。
或者，终端在一个频段组合中上报一组能力，该组能力用于表示该频段组合所包括的全部载波的能力之和。沿用上述举例，一个频段组合中包括3个载波，在载波1上终端接收PDSCH的最大数目为N1，在载波2上终端接收PDSCH的最大数目为N2，在载波3上终端接收PDSCH的最大数目为N3，则终端向基站上报一组能力，该组能力包括终端在该频段组合上包括的3个载波上接收PDSCH的最大数目总和N，该N的取值为N1、N2与N3三者之和。或例如，对于一个包含载波1和载波2的频段组合，终端上报一组能力{2}，其表示终端在上述载波1和载波2上总共能够同时传输的PDSCH最大数目为2。
示例的，针对一个频段组合，终端上报多组参数，不同组的参数指示了终端在所述频段组合中的不同能力。例如其中一组参数组可以携带于特征集组合(FeatureSetCombination)信元中。每组参数组中包含了终端在每个频段或载波上的相关能力参数组。例如，FeatureSetCombination信元中包含CC下行链路特征集(FeatureSetDownlinkPerCC)信元。FeatureSetDownlinkPerCC信元中指示了对应载波上的PDSCH相关的能力。具体的，可以包括终端在对应载波上最大支持的同时传输PDSCH数目。其中，当终端支持大于1个PDSCH同时传输时，上述多个PDSCH在时域上可以完全重叠或部分重叠，频域上可以完全重叠、部分重叠或不重叠。不同类型的最大同时传输的PDSCH数目可以独立上报，也可以联合上报等。可选的，PDSCH相关的参数空缺代表终端在这个载波上支持的PDSCH的最大数目为0。或者，对于一个频段组合中的所有载波，终端上报其总共支持的最大同时传输的PDSCH的数目。上述能够同时传输的PDSCH可以在时域和/或频域部分重叠或完全重叠等，包括三种情况：1、其中任意两个PDSCH时域完全或部分重叠，频域上重叠；2、其中任意两个PDSCH时域上全部或部分重叠，频域上部分重叠；3、其中任意两个PDSCH时域上全部或部分重叠，频域上完全不重叠。不同类型的最大同时传输的PDSCH数目可以独立上报，也可以联合上报等。
需要说明的是，在上述描述中，是以频段组合的方式为例，描述终端上报终端能力的，并不作为对本申请的限定。例如，终端还以以频段的组合、载波的组合、或频段与载波的组合等方式，上报终端能力等。
应当指出，在上述描述中，是以终端以载波为粒度上报终端能力为例描述的。终端上报能力的粒度还可以是小区、频段、小区组或BWP等，例如，终端可以向基站上报每个频段所支持传输PDSCH的最大数目等，或者上报每个小区所支持传输PDSCH的最大数目等，或者上报每个小区组所支持传输PDSCH的最大数目，或者上报每个BWP传输PDSCH的最大数目等。本申请的描述中，对于频段、载波、CC、小区、小区组或BWP的关系作如下说明。例如，FR1的频段范围是410MHz-7125MHz，其包括几十个频段，如频段n18为815MHz-830MHz。FR2的频段范围是24250MHz-52600MHz，其包括6个频段，如频段n257为26500MHz-29500MHz。每个频段包含多个载波，每个载波对应一个传输带宽(transmission bandwidth)和一个中心频率。在CA中，涉及多个载波的聚合，每个载波称为一个载波单元(component carrier，CC)，每个CC对应一个独立的小区，通常可以将一个CC等同于一个小区。在DC场景下，存在小区组的概念，在主站下的小区组包括主小区组和辅小区组，在辅站下的小区组包括主辅小区组和辅小区组，每个小区组中包括至少一个小区。BWP是在NR中新引入的概念，其中文含义为部分带宽，其含义是相对于系统 带宽，终端只使用系统带宽的一部分带宽，这样可以节约终端成本，降低终端功耗，可以为每个终端的每个小区配置多个BWP，但在同一时刻，激活一个BWP，终端在该小区利用激活的BWP与基站进行通信。可以简单的认为，频段、载波、CC、小区、小区组或BWP存在以下关系：一个频段中包括一个或多个载波，载波还可称为CC，一个载波对应于一个小区，小区可属于一个小区组，即小区与小区组可存在对应关系。一个小区可包括一个或多个BWP，小区与BWP间存在对应关系。
步骤201：终端接收来自基站的第一信令，该第一信令用于指示至少一种配置。相应的，基站向终端发送第一信令。
在一种设计中，所述第一信令为RRC信令，所述至少一种配置包括以下至少一种：
PDSCH的数目；例如，接收PDSCH的数目；可选的，当所述PDSCH的数目为多个时，在同一时刻或同一时间单元，所述多个PDSCH在时域部分重叠或完全重叠。
PUSCH的数目；例如，发送PUSCH的数目；可选的，当所述PUSCH的数目为多个时，在同一时刻或同一时间单元，所述多个PUSCH在时域部分重叠或完全重叠。
盲检DCI的CORESET POOL的数目；例如，盲检DCI的CORESET POOL的数目；可选的，当CORESET POOL的数目为多个时，在同一时刻或同一时间单元，所述多个CORESET POOL上盲检DCI的时间单元部分重叠或完全重叠。
空分复用的传输层数；
跟踪的TCI状态的数目；
或HARQ进程的数目等。
应当指出，在本申请中，终端基带处理能力是终端在某一个时刻处理PDSCH、PUSCH等的总能力，如果传输不是在时间上同时发生，则不能称为基带处理能力的共享，因此在本申请的描述中，所谓时域完全重叠或部分重叠，体现在多个PDSCH、PUSCH、CORESET POOL等在同一时刻或同一时间单元对终端能力的共享。
在本申请中，基站可根据终端上报的终端能力，确定至少一种配置。
在一种设计中，基站可以根据终端上报的终端能力，为每个小区指示至少一种配置。例如，终端在向基站上报的终端能力中表明：在小区1中，终端接收PDSCH的最大数目为10，则基站根据终端上报的接收PDSCH的最大数目10，可以为小区1配置多种配置。例如，具体的配置为配置1、配置2和配置3。在配置1中，终端在小区1接收PDSCH的数目为5，在配置2中，终端在小区1中接收PDSCH的数目为6，在配置3中，终端在小区1中接收PDSCH的数目为7。应当指出，无论哪种配置，都应当满足终端上报的能力，即小于终端上报的在小区1中接收PDSCH的最大数目10。或者，在配置时不受上述终端上报的能力的限制，但在后续激活时，需要受到终端上报能力的限制，即基站不激活超出终端上报能力的配置。以基站为第一小区配置至少一种配置为例，则所述第一信令用于指示第一小区的至少一种配置与索引的对应关系，所述第一小区的至少一种配置是根据终端上报的终端能力确定的。在下述步骤202中，基站向终端发送的第二信令，该第二信令中包括第一索引的指示信息。终端根据基站指示的第一小区的至少一种配置与索引的对应关系，确定第一索引对应的第一配置。终端在第一小区中工作在第一配置上。
或者，对于一个频段组合中包括载波1和载波2，针对载波1和载波2，则基站可以分别确定三组配置，该载波1的三组配置分别为第一组配置{2}、第二组配置{1}和第三组配置{1}，载波2的三组配置分别为第一组配置{0}、第二组配置{1}和第三组配置{0}。基 站可以先激活两个载波的第一组配置进行传输，当终端接收到基站发送的下述步骤202中的第二信令时，根据第二信令的指示，载波1的配置从第一组配置切换到第二组配置，载波2的配置由第一组配置切换到第二组配置，从而基站激活了上述两个载波的第二组配置进行传输。
应当指出，针对上述第一种能力上报方案，每组配置中的取值都应当不超过终端上报的相应能力参数组中针对这个载波的能力。针对上述第二种能力上报方案，所有载波的同组配置中取值的总和应当不超过终端上报的能力。仍沿用上述举例，一个频段组合中包括载波1和载波2，基站分别为上述载波1和载波2确定三组配置，则载波1的第一组配置{2}和载波2的第一组配置{0}可认为是同组配置。同样的，载波1的上述第二组配置和载波2的上述第二组配置也认为是同组配置；载波1的上述第三组配置和载波2的上述第三种配置也认为是同组配置。对于同组配置中同时传输PDSCH的总数目不应该超过终端上述第二种能力上报方案中上报的总能力。或者，对于这个频段组合，每组配置无需遵循终端上报的能力。但后续，基站向终端发送下述步骤202中的第二信令，动态激活不同载波时，终端同时激活的所有载波需要满足终端上报的能力。
在本申请中，对于激活的主载波或主小区或主小区组上最大同时传输的PDSCH的数目至少为1个。对于激活的辅载波或辅小区或辅小区组上最大同时传输的PDSCH的数目可以0。
在另一种设计中，基站可以根据终端上报的终端能力，确定不同BWP与配置的对应关系。所述第一小区中不同BWP对应的配置是根据所述终端上报的终端能力所确定的。例如，若终端以小区、载波或CC为粒度上报终端能力，载波或CC对应一个小区，每个小区包括至少一BWP，则终端根据在某一个小区或载波或CC上报的最大接收PDSCH的数目，为该小区中的至少一个BWP分别配置对应的配置，但应满足终端上报的能力。例如，某小区中包括第一BWP和第二BWP，终端向基站上报终端在该小区中最大接收PDSCH的数目为5，则基站根据该小区的能力，确定该小区包括的第一BWP的配置为配置1，该小区包括的第二BWP的配置为配置2。例如，配置1为终端在第一BWP中接收PDSCH的数目为2，配置2为终端在第二BWP中接收PDSCH的数目为3等。在该设计中，下述步骤202中，基站向终端发送对应激活的BWP的索引，可称为第一索引。终端在根据第一信令，确定第一索引时，确定第一索引对应的第一BWP，激活该第一BWP。且终端在第一BWP工作在该第一BWP存在对应关系的配置1上。在该设计中，无需设计专门的信令用于指示不同配置的切换，利用现有的BWP的切换信令，可间接指示不同配置的切换，节省信令开销。
在本申请中，对于不同的BWP，其配置可以相同或不同，并且应该满足终端上报的能力。对于上述第一种能力上报方案，每个BWP的取值应当不超过终端上报的相应能力参数组中针对这个频段或载波或对应的小区或小区组的能力。对于上述第二种能力上报方案，所有频段或载波或对应的小区或小区组或BWP的同组BWP中取值的总和应当不超过终端上报的能力。或者，对于某个频段组合，或其中的某个频段或载波或对应的小区或小区组，配置的BWP无需遵循终端上报的能力，但在后续步骤202中，基站动态激活或切换不同的BWP时，终端同时激活的所有BWP需要满足终端上报的能力。
应当指出，对于同时激活的BWP，主载波或主小区或主小区组对应的BWP上最大同时传输的PDSCH的数目至少为1个。辅载波或辅小区或辅小区组上最大同时传输的 PDSCH数目可以为0。
步骤202：终端接收来自基站的第二信令，该第二信令用于指示上述至少一种配置中的第一配置。相应的，基站向终端发送第二信令。
在本申请中，该第二信令包括DCI或MAC控制元素(control element，CE)等。基站根据网络的状态，向终端发送MAC CE或DCI等，动态切换不同的配置。基站可根据网络的状态，实时的向终端发送MAC CE或DCI等，向终端指示不同的配置。例如，在时刻1，基站可根据网络的状态，确定终端工作在第一配置下，可以较好的利用终端的基带处理能力，则基站可向终端发送MAC CE或DCI，用于指示第一配置。终端接收到上述MAC CE或DCI时，工作在第一配置。之后，在时刻2，网络的状态发生变化，则基站确定终端工作在第二配置下，可以更好的利用终端的基带处理能力。则基站可向终端发送MAC CE或DCI等，用于指示第二配置。终端在接收到该MAC CE或DCI时，由第一配置切换到第二配置。终端根据基站的MAC CE或DCI的指示，可实时的切换不同的配置。相对于，目前方案，通过RRC半静态配置的方式，可提高终端基带处理能力的利用率，提高上下行吞吐等。
例如，基站同时使用两个下行载波向终端进行传输，分别为载波1和载波2。载波1的三组配置为{2}、{1}、{1}，载波2的三组配置为{0}、{1}和{0}。基站可激活上述两个载波的配置1进行传输。即在载波1上，终端同时传输的PDSCH的数目为2，在载波2上同时传输PDSCH的数目为0。基站通过对网络设备的采集，发现载波1有些拥塞，则基站可以向终端发送DCI或MAC CE信令，指示终端在载波1和载波2上均切换到第二组配置上，终端在第二组配置中，在载波1和载波2分别接收一个PDSCH，从而有效缓解了载波1的拥塞，提高了传输速率。在该设计中，MAC CE或DCI等信令，可具体指示需要切换的模式的索引。
或者，在另一种设计中，针对上述引入BWP的方案，预先为不同BWP配置不同的配置的方案。在该方法中，上述MAC CE或DCI，可指示不同BWP的切换。例如，终端在接收到MAC CE或DCI时，该MAC CE或DCI指示终端切换到BWP2，则终端由当前工作的BWP1切换到BWP2，获取该BWP2预配置或存在对应关系的配置。之后，在BWP2上工作在具体的配置上。在该设计中，MAC CE或DCI用于指示BWP的索引。举例来说，基站同时使用两个下行载波与终端进行传输，分别称为CC1和CC2，每个载波上分别配置了三个BWP，载波1上的三个BWP，分别为BWP1_CC1、BWP2_CC1、BWP3_CC1，其配置的接收PDSCH的最大数目分别为{2}、{1}、{1}。载波2的三个BWP，分别为BWP1_CC2、BWP2_CC2和BWP3_CC2，其配置的传输PDSCH的最大数目分别为{0}、{1}、{0}。在一种方案中，基站先激活BWP1_CC1和BWP1_CC2。之后，基站根据实时的网络状态，例如负载和信道质量等，基站向终端发送MAC CE DCI信令，指示终端由BWP1_CC1切换到BWP2_CC2，则终端由BWP1_CC2切换到BWP2_CC2，则在BWP2_CC2工作在其对应的配置上。
步骤203：终端根据所述第一配置，与基站进行通信。相应的，基站根据所述第一配置，与终端进行通信。
在本申请中，以上述第一配置包括传输PDSCH的最大数目为例。沿用上述举例，一个频段组合包括载波1和载波2，则在载波1中的第一组配置为{2}，在载波2中的第一组配置为{0}。则终端在工作在第一配置时，在载波1中同时接收2个PDSCH，在载波2中 不接收PDSCH。
应当指出，在上述描述中，主要以载波为粒度上报或配置终端传输PDSCH的最大数目为例描述的。例如，终端上报每个载波传输PDSCH的最大数目，或者，基站为终端分配每个载波传输PDSCH的最大数目等，并不作为对本申请的限制。在本申请中，还可以频段、小区、小区组或BWP等粒度，上报终端能力，或者基站为终端配置等。例如，终端可以上报每个频段、小区、小区组或BWP上，传输PDSCH的最大数目。或者，基站可以配置每个频段、小区、小区组或BWP上，传输PDSCH的最大数目等。
在本申请中，可实现终端在多个频段或载波的PDSCH基带能力共享。因此，基站可以根据信道、负载等信息，实时动态地调整为终端服务的频段或载波，将终端的基带能力运用到最合适的频段或载波上，避免终端基带处理能力的浪费。能够提高空口总传输速率，降低服务时延，实现动态负载均衡。
需要说明的是，在上述图2的流程中，是以基站通过第一信令向终端配置至少一种配置；后续，基站通过第二信令向终端指示上述至少一种配置中的任一种配置，终端工作在第二信令所指示的配置上，与基站通信为例的，并不作为对本申请的限定。比如，在一种示例中，基站通过第一信令向终端配置一种配置，则终端可以直接工作在该配置即可，无需再通过第二信令指示，进一步节省信令开销。
在一种设计中，上述图2所示的方案，可应用于single-TRP场景。针对multi-TRP，可能在终端能力上报和基站为终端分配配置时，还需要考虑TRP的影响。Single-TRP情况下，只涉及基带能力在频域的共享，multi-TRP的存在引入了空域维度，既涉及基带能力在频域的共享，也涉及基带能力在空域的共享，基带能力要在不同TRP的不同频段/载波上进行动态分配，进一步提升基带能力共享的灵活性。例如，该multi-TRP场景，与上述图2所示方案的主要区别在于：在终端向基站上报终端的能力时，该能力中需要包括终端在每个频段或载波上，所支持的与multi-TRP相关的参数。例如，终端在这个频段或载波上能够同时连接的TRP的数目，或者，每个CORESET POOL能够接收的PDSCH的最大数目等。后续，网络设备根据终端上报的能力，确定至少一种配置时，需要考虑TRP的影响。以基站为终端配置PDSCH的数目为例，如果在single-TRP场景下，如果为一个载波同时配置接收2个PDSCH，则该载波可能采用频分的方式，传输该2个PDSCH。例如，将该载波划分为2个频域资源，第一个频域资源传输PDSCH1，第二个频域资源传输PDSCH2等。而在multi-TRP场景下，如果一个载波同时配置接收2个PDSCH，则该2个PDSCH可采用空分的方式。比如，将CC1配置给2个TRP，则可配置终端在CC1下，通过TRP1接收PDSCH1；同样在CC1下，通过TRP2接收PDSCH2等。当上述图2所示流程中的方法，应用于multi-TRP的场景时，本申请提供一种方法，使能PDSCH基带处理能力在频域和空域的动态共享，至少包括：
一、终端向基站上报终端能力。终端能力是该终端在一个频段组合内的能力。一个频段组合包含一个或多个频段或载波，对应终端的一个或多个小区或小区组或BWP。
终端能力上报方法一：终端上报多个能力参数组，每个能力参数组对应于所述频段组合中的一个频段或载波，其包含终端在这个频段或载波上具有的与multi-TRP相关的能力。
例如，在终端能力上报方法一中，对于一个频段组合，终端上报多组能力参数，每个能力参数对应所述频段组合中的一个频段或载波，其包含终端在这个频段或载波上具有的多种终端能力。例如，多个能力参数组的集合可以为FeatureSetCombination，其中的每个 能力参数组FeatureSetDownlinkPerCC包含每个频段或载波上的多种终端能力，在多种终端能力中，包含与multi-TRP相关的能力，与multi-TRP相关的能力参数组可以是multi-TRP。
1、multi-TRP可以包含终端在这个频段或载波或小区或小区组或BWP上的支持的最大CORESET POOL的个数，其代表终端在这个频段或载波或小区上能够同时连接的最大TRP的数目。
2、multi-TRP可以包含终端在这个频段或载波或小区或BWP上能够配置的最大CORESET数目。
3、multi-TRP可以包含终端在这个频段或载波或小区或BWP的每个CORESET POOL上能够配置的最大CORESET数目。
4、muti-TRP可以包含终端在这个频段或载波或小区或BWP的每个CORESET POOL能够发送的最大PDSCH数目。

例如，在终端能力上报方法二中，对于一个频段组合，终端上报多个能力参数组。每个能力参数组一种终端能力，例如，参数组multi-TRP-PerBC对应了该频段组合中与multi-TRP对应的终端能力。每个能力参数组包含多个子参数组，每个子参数组对应一个频段或载波，例如，参数组multi-TRP-PerBC包含子参数组multi-TRP-PerCC，子参数组multi-TRP-PerCC对应每个频段或者载波与multi-TRP对应的终端能力。

二、基站接收终端上报的能力，并根据终端上报的能力对其进行配置与调度。
配置与调度方法一：基站通过小区配置的激活或去激活来实现终端的PDSCH基带能力在多个频段或TRP的共享。例如，对于一个频段组合中的一个频段或载波，基站可以按照多个参数组给终端配置多组服务小区配置，每组服务小区配置中包括一套没有PDSCH的辅小区配置，不包含一套没有PDSCH的主小区配置，但同时只能激活一套服务小区配置。基站在一个频段组合中的所有频段或载波上同时激活的所有小区能够同时传输的PDSCH数目和需要满足一个参数组对应的终端能力。
配置与调度方法二：基站可以通过BWP的激活和/或去激活来实现终端的PDSCH基带能力在多个频段、载波或TRP的共享。在这种情况下，对于一个频段组合中的一个频段或载波或服务小区，基站可以按照多个参数组给终端配置多个BWP，辅小区可以包含没有PDSCH的BWP，主小区不包含没有PDSCH的BWP。基站同时激活的所有BWP能够同时传输的PDSCH数目和需要满足一个参数组对应的终端能力。
在该方法实施例中，实现终端在多个频段或载波和TRP之间的PDSCH基带能力共享，因此，基站可以根据信道和负载等信息，实时动态地调整为终端服务的频段、载波和TRP，将终端的基带能力运用到最合适的频段、载波和TRP上，避免终端基带能力的浪费。最终，能够提高空口总传输速率，降低服务时延，实现动态负载均衡。
在该实施例中，主要包括以下改进：第一方面，增加了终端上报的与multi-TRP和PDSCH相关的基带能力信息，便于基站依据增加的上报信息进行精确的动态调控和终端基带能力共享。第二方面，在multi-TRP场景下，允许基站在一个频段或载波上通过2个以上TRP调度，允许基站通过L1层信令对不同配置进行激活或去激活，使能了终端PDSCH基带能力在不同频段或载波和不同TRP的动态共享。
以基站为终端配置的至少一种模式中包括跟踪的TCI状态为例，本申请提供一种方法，使能TCI状态(states)基带处理能力在频域和空域的动态共享，至少包括：
一、终端向基站上报终端能力。终端能力是该终端在一个频段组合内的能力。一个频段组合包括一个或多个频段或载波，对应终端的一个或多个小区或小区组或BWP等。
终端能力上报方法一：终端上报多个能力参数组，每个能力参数组对应所述频段组合中的一个频段或载波，其包含终端在这个频段或载波上具有的与multi-TRP相关的能力。
例如，在终端能力上报方法一中，对于一个频段组合，用户上报多个能力参数组，每个能力参数组对应所述频段组合中的一个频段或载波，其包含用户在这个频段或载波上具有的多种终端能力，例如，多个能力参数组的集合可以为FeatureSetCombination，其中的每个能力参数组FeatureSetDownlinkPerCC包含每个频段或载波上的多种终端能力，在多种终端能力中，包含与multi-TRP相关的能力，与multi-TRP相关的能力参数组可以为multi-TRP。multi-TRP可以包含用户在这个频段或载波或小区或BWP的每个CORESET POOL上能够支持的最大的TCI state的数目。
终端能力上报方法二：终端上报多个能力参数组，每个能力参数组对应一种能力，在与multi-TRP相关的能力参数组中，包含多个子参数组，每个子参数组对应这个频段组合中的一个频段或载波上具有的与multi-TRP相关的能力。
例如，在终端能力上报方法二中，对于一个频段组合，用户上报多个能力参数组。每个能力参数组对应一种终端能力，例如，参数组multi-TRP-PerBC对应了该频段组合中与multi-TRP对应的终端能力。每个能力参数组包含多个子参数组，每个子参数组对应一个频段或者载波，例如，参数组multi-TRP-PerBC包含子参数组multi-TRP-PerCC，子参数组multi-TRP-PerCC对应每个频段或者载波与multi-TRP对应的终端能力。
二、基站接收终端上报能力，并根据终端上报的能力对其进行配置和调度。
配置与调度方法一：基站可以通过小区配置的激活或去激活来实现终端的TCI states能力在多个频段或载波或TRP的共享。在这种情况下，对于一个频段组合中的一个频段或载波，基站可以按照多个参数给终端配置多组TCI state配置，但同时只能激活一组TCI state配置。基站在一个频段组合中的所有频段或载波上同时激活的所有TCI state配置需要满足一个参数组对应的终端能力。
配置与调度方法二：基站可通过BWP的激活或去激活来实现终端的TCI state能力在多个频段或载波的共享。在这种情况下，对于一个频段组合中的一个频段或载波或服务小区，基站可按照多个参数组给终端配置多个BWP，基站同时激活的BWP上的所有TCI配 置需要满足一个参数组对应的终端能力。
在该方法实施中，实现终端在多个频段、载波或多个TRP之间的TCI state能力共享。因此，基站可以根据信道、负载等信息，实时动态地调整终端在不同频段或载波、和不同TRP上跟踪TCI state，将终端的基带能力运用到最合适的频段、载波或TRP上，避免终端基带能力的浪费。最终，提高空口传输速率，降低服务时延，实现动态均衡。
本申请实施例主要作如下改进：第一方面，增加了终端上报的与multi-TRP和TCI states相关的基带能力信息，便于基站依据增加的上报信息进行精准的动态调控和终端基带能力共享；第二方面，在multi-TRP场景下，允许基站在一个频段或载波上通过2个以上TRP调度终端，终端可以在2个以上TRP上跟踪TCI state；第三方面，基站通过RRC信令为终端的同一服务小区配置多套参数或BWP，允许基站通过L1信令对不同配置进行激活和去激活，使能了终端TCI states跟踪能力在不同频段或载波和不同TRP上的动态共享。
以基站为终端配置的至少一种模式中包括：HARQ进程的数目为例，本申请还提供一种方法，使能HARQ进程在频域的动态共享，至少包括：

例如，针对一个频段组合，终端上报多组参数组，不同参数组指示了终端在所述频段组合中的不同终端能力，例如其中一组参数组可以为FeatureSetCombination。每组参数组包含了终端在每个频段或载波上的相关能力参数组，例如FeatureSetCombination包含了FeatureSetDownlinkPerCC。FeatureSetDownlinkPerCC中指示了终端在每个频段或载波上的HARQ进程相关的能力。具体的，可以包含终端在这个频段或载波上最大支持的同时传输的HARQ进程个数。
终端能力上报方法二中，终端上报一组能力，该组能力包含一个能力参数，这个能力参数指示了终端在这个频段组合中的所有频段或载波或对应的小区或小区组或BPW上总共最大能够同时传输的HARQ进行数目。
例如，对于一个频段组合中的所有频段或载波(或者对应的小区或小区组或BWP)，终端上报其总共支持的最大同时传输的HARQ进程数目。
二、基站接收终端上报的能力，并根据终端上报的能力对其进行配置与调度。
配置与调度方法一：对于这个频段组合中的任意一个频段或载波或对应的小区或小区组，基站可以进行多组配置，每组配置指示了终端在这个频段或载波或对应小区或小区组上最大能够同时传输的HARQ进程数目，对于不同组的配置，其取值可以不同。每组配置都应当满足终端上报能力。
其中，对于终端能力上报方法一，每组配置中的取值应当不超过终端上报的相应能力参数组中针对这个频段或载波或对应的小区或小区组的能力。
对于终端能力上报方法二，所有频段或载波或对应的小区或小区组或BWP的同组配置中取值的总和应当不超过终端上报的能力。
对于这个频段组合，或其中的某个频段或载波或对应的小区或小区组，基站向终端发 送MAC CE或DCI信令，动态切换不同的配置。
或者，对于这个频段组合，或其中的某个频段或载波或对应的小区或小区组，每组配置无需遵循终端上报的能力。基站向终端发送MAC CE或DCI信令，动态激活不同的频段或载波或小区或小区组，终端同时激活的所有频段或载波或对应的小区或小区组需要满足终端上报的能力。
配置与调度方法二，对于这个频段组合中的任意一个频段或载波或对应的小区或小区组，终端可以配置多个BWP，并配置每个BWP上最大能够同时传输的HARQ进程数目。
对于不同的BWP，其取值可以不同，并且应当满足终端上报的能力。
对于终端能力上报方法一，每个BWP的取值应当不超过终端上报的相应能力参数组中针对这个频段或载波或对应的小区或小区组的能力。
对于终端能力上报方法二，所有频段或载波或对应的小区或小区组或BWP的同组BWP中取值的总和应当不超过终端上报的能力。
对于这个频段组合，或者其中的某个频段或载波或小区或小区组，基站向终端发送MAC CE或DCI信令，动态切换不同的BWP。
或者，对于这个频段组合，或其中的某个频段或载波或对应的小区或小区组，配置的BWP无需遵循终端上报的能力。基站向终端发送MAC CE或DCI信令，动态激活或切换不同的BWP，终端同时激活所有BWP需要满足终端上报的能力。
在本申请中，实现终端在多个频段/载波的HARQ进程处理能力共享。因此，基站可以根据信道、负载等信息，实时动态地调整为终端服务的频段或载波，将终端的基带能力运用到最合适的频段或载波上，避免终端基带能力的浪费。最终，能够提高空口总传输速率，降低服务时延，实现动态负载均衡。
本申请在以下多个方面进行了改进。第一方面，增加了终端上报的与HARQ进程相关的基带能力信息，上报在多个频段或载波上的总能力，或根据总能力上报多组每频段或每载波上的能力，便于基站依据增加的上报信息进行精确的动态调控和终端基带能力共享；第二方面，基站通过RRC信令为终端的同一服务小区配置多套参数或BWP，允许基站通过L1层信令对不同配置进行激活或去激活，使能了终端HARQ进程处理能力在不同频段或载波上的动态共享。
应当指出，本申请重点描述PDSCH传输、TCI states跟踪和HARQ进程维护等基带能力在频域和/或空域的动态共享，并不作限对本申请的限定。例如，本申请的方案还适用于PUSCH传输、PDCCH检测、CSI-RS资源配置、同时处理的传输层数等基带能力在频域和/或空域的动态共享等。
