为便于理解本申请实施例，下面先对本文涉及的相关术语进行简单的介绍。
1、时隙(slot)
时隙是时域资源的最小调度单位，一个时隙包括至少一个符号。符号包括上行符号(即用于上行传输的符号)、下行符号(即用于下行传输的符号)和灵活符号(根据网络配置可以用于上行传输或下行传输或用作保护间隔)。包含的符号全部为上行符号的时隙可以称为上行时隙，本申请实施例中用U表示。包含的符号全部为下行符号的时隙可以称为下行时隙，本申请实施例中用D表示。包含的符号为上行符号、下行符号和灵活符号中的多种符号的时隙可以称为灵活时隙，本申请实施例中用S表示。
NR中，根据不同的子载波间隔，1毫秒(ms)中可以包括不同数量的时隙，例如，当子载波间隔为15千赫兹(kHz)时，1ms包括1个时隙，该时隙占用1ms。当子载波间隔为30kHz时，1ms包括2个时隙，每个时隙占用0.5ms。
其中，上行符号例如可以称为单载波频分多址(single carrier-frequency division multiple access，SC-FDMA)符号或正交频分多址(orthogonal frequency division multiplexing，OFDM)符号。下行符号例如可以称为OFDM符号。
2、时分双工(time division deplux，TDD)
通信系统的一种双工通信技术，用于分离接收和发送的信道，即上下行链路。采用TDD模式的通信系统中，上下行链路使用相同的频域资源，通过不同时域资源来区分上行链路和下行链路。
3、频分双工(time division depluxing，FDD)
通信系统的一种双工通信技术，用于分离接收和发送的信道，即上下行链路。采用FDD模式的通信系统中，上下行链路使用相同的时域资源，通过不同频域资源来区分上行链路和下行链路，例如上行频率范围与下行频率范围不同。
4、多载波上行传输
多载波上行传输是指上行方向上，终端与网络设备之间存在多个载波。终端可以接入一个网络设备，多个载波可以包括终端与一个网络设备之间的载波，或者，终端可以同时接入两个网络设备，多个载波可以包括终端分别与两个网络设备之间的载波。
示例性地，多载波上行传输的场景可以包括载波聚合(carrier aggregation，CA)、双连接(dual connectivity，DC)和辅助上行链路(supplementary uplink，SUL)等场景。
示例性地，多载波上行传输时，可以通过时分复用(time division multiplexing，TDM)方式进行上行传输，或者，可以通过并发方式进行上行传输。
5、CA
CA是将2个或更多个载波聚合在一起以支持更大的传输带宽的技术。CA可以分为上行CA和下行CA。针对上行CA，终端可以根据其能力在多个载波上同时接收或发送。示 例性地，参见图2，终端可以在载波1和载波2之间进行上行CA，从而在网络设备和终端之间支持更大的上行传输带宽，提升上行传输性能。
6、DC
在目前的通信系统中，终端支持同时接入到两个不同节点，这种接入方式称为DC。该情况下，终端可以利用两个节点中的一个或多个的无线资源进行传输，该两个节点可以是相同制式或者是不同制式的。
这两个不同节点中一个节点为主节点，另一个节点为辅节点。两个节点之间的链路可以是非理想回传链路，也可以是理想回传链路。这两个不同节点可以为不同的网络设备，也可以为同一网络设备中的不同的模块，一个模块可以对应一个小区。
示例性地，这两个不同节点可以为基于演进型分组核心网(evolved packet core，EPC)的非独立(Non-Standalone，NSA)组网场景下的两个基站，该情况下，这两个基站可以为LTE基站和NR基站。这两个不同节点也可以为独立组网(Standalone，SA)场景下的两个基站，该情况下，这两个基站可以均为LTE基站，或者，均为NR基站。其中，两个基站均为NR基站的DC场景可以称为NR DC场景。两个基站均为LTE基站的DC场景可以称为LTE DC场景。
示例性地，DC可以是多制式(multi-radio，MR)-DC，MR-DC可以包括演进的通用陆地无线接入(Evolved Universal Terrestrial Radio Access，E-UTRA)与NR的DC(E-UTRA-NR Dual Connectivity，EN-DC)、下一代(Next Generation，NG)无线接入网络(Radio Access Network，RAN)E-UTRA与NR的DC(NG-RAN E-UTRA-NR Dual Connectivity，NGEN-DC)、NR与E-UTRA的DC(NR-E-UTRA Dual Connectivity，NE-DC)、或者NR与NR的DC(NR-DC)。
其中，终端与两个不同节点中的一个节点之间可以通过多个载波进行通信，示例性地，参见图3，若两个不同节点为LTE基站和NR基站，终端可以通过多个载波与LTE基站通信，这多个载波之间可以进行上行CA和/或下行CA。也可以采用多个载波与NR基站通信，这多个载波之间可以进行上行CA和/或下行CA。
7、SUL
SUL是为终端配置的补充上行链路。目的是为了提高终端的上行覆盖。示例性的，参见图4，终端可以通过正常上行链路(normal uplink，NUL)发送上行信息，也可以通过SUL发送上行信息。NUL的覆盖范围可以小于SUL的覆盖范围。SUL场景下的多个载波是指SUL和NUL。
8、射频能力
本申请实施例中的射频能力包括射频通道能力和/或其他射频能力。其中，射频通道能力可以包括以下信息中的一种或多种：多输入多输出(multiple-input multiple-output，MIMO)层数、探测参考信号(sounding reference signal，SRS)天选能力、射频通道的数量等。其他射频能力可以包括以下信息中的一种或多种：上行发射功率、单载波功率(ue-PowerClass)、发射机切换是否会影响接收机(txSwitchImpactToRx)的信息。
9、载波的射频通道能力
一个载波的射频通道能力表征了该载波的射频通道的数量。例如，一个载波支持的(即最大可以采用的)射频通道能力表征了该载波支持的(即最大可以采用的)射频通道的数 量。
由于载波的射频通道的数量可以直接通过一个数值显示指示，也可以通过该载波的MIMO层数，SRS天选能力等隐式指示。因此，载波的射频通道能力可以包括以下信息中的一个或多个：指示该载波的射频通道的数量的数值、该载波的MIMO层数、该载波的SRS天选能力等，载波的射频通道能力可以通过该射频通道能力中包括的信息表征。
其中，SRS天选能力是指该载波支持的发送天线和接收天线的数量。若发送天线数量记为x，接收天线数量记为y，发送天线记为T，接收天线记为R，则该载波的SRS天选能力可以记为xTyR，x和y均为大于0的整数。
其中，一个载波的MIMO层数与该载波的射频通道的数量相同，例如一个载波的最大MIMO层数与该载波支持的射频通道的数量相同。一个载波的SRS天选能力中的发送天线的数量与该载波的射频通道的数量相同，例如一个载波的SRS天选能力中的最大发送的天线数量与该载波支持的射频通道的数量相同。
为了方便，在下文的描述中“射频通道能力表征x个射频通道”描述为“射频通道能能力为xT”，x为大于0的整数。
10、射频通道的共享机制
一个载波可以支持1个射频通道，也可以支持多个射频通道。在实际实现时，不同的载波可以共享射频通道，即同一个射频通道在不同的时间可以给不同的载波使用。示例性地，参见图5，载波1可以支持射频通道1和射频通道2，载波2仅支持射频通道2。射频通道2在不同的时间可以给不同的载波使用。例如，在时间段1中，射频通道2可以给载波1使用，该情况下，在时间段1中，开关1工作在状态1。在时间段2中，射频通道2可以给载波2使用，该情况下，在时间段2中，开关1工作在状态2。
11、载波单发
载波单发是指只在该载波上进行上行发送。
载波单发可以有两种情况，一种是以单载波发送，即终端始终在该载波上进行上行发送。另一种是该载波与其他载波TDM，该情况下，该载波与其他载波中的任意一个载波的上行发送所采用的时域资源不重叠。针对该载波而言，该载波是单发的，针对由该载波和其他载波组成的多个载波而言，该多个载波是TDM的。
终端在多个载波上采用TDM方式进行发送时，多个载波中每个载波的上行发送所采用的时域资源不与该多个载波中的其他任意一个载波的上行发送所采用的时域资源重叠。其中，该多个载波可以为终端支持的全部载波中的部分或全部。可以理解，多个载波不会在相同的时域资源上进行上行发送。
示例性地，针对2.6G赫兹(Hz)的载波(以下简称2.6G载波)和3.5GHz的载波(以下简称3.5G载波)，若两个载波的时隙配置如图6所示，则终端可以通过2.6G载波在2.6G载波对应的时隙3进行上行发送，终端可以通过3.5G载波在3.5G载波对应的时隙9和3.5载波对应的时隙4(即2.6G载波的时隙2的前半个时隙)进行上行发送，则2.6G载波或3.5G载波是TDM的。
TDM发送方式也可以称为分时发送方式等。
本申请实施例中的载波单发可以包括单载波发送和/或该载波与其他载波TDM。
12、载波单发时的射频能力
载波单发时的射频能力包括该载波以单载波发送时的射频能力，和/或，该载波与其他载波TDM时的射频能力。一个载波以单载波发送时的射频能力和该载波与其他载波TDM时的射频能力可以相同也可以不同。
13、多个载波并发
并发为数据发送的一种方式。终端在多个载波上并发时，多个载波中每个载波的上行发送所采用的时域资源与其他载波中的每个载波的上行发送所采用的时域资源重叠。其中，多个载波可以为终端支持的全部载波中的部分或全部。
示例性地，参见图6，在2.6G载波对应的时隙2的前半个时隙(即3.5G载波对应的时隙4)，终端在2.6G载波和3.5G载波上同时进行上行发送，则在2.6G载波对应的时隙2的前半个时隙(即3.5G载波对应的时隙4)，2.6G载波和3.5G载波是并发的。
需要说明的是，多个载波重叠的上行时域资源中，多个载波如何在该重叠的上行时域资源上发送，可以决定该多个载波是TDM的还是并发的。例如，针对2.6G载波和3.5G载波，若两个载波的时隙配置如图7所示，若终端通过3.5G载波在3.5G载波对应的时隙4和时隙9发送，终端通过2.6G载波仅在2.6G载波对应的时隙3上发送，则3.5载波和2.6载波是以TDM方式进行上行发送的。若终端通过3.5G载波在3.5G载波对应的时隙4和时隙9发送，终端通过2.6G载波在2.6G载波对应的时隙2、时隙3和时隙4上发送，则在3.5G载波对应的时隙4和时隙9上，3.5G载波和2.6G载波并发的。
另外，需要说明的是，终端可能支持多个载波，该多个载波中的部分载波可能是TDM的，部分载波可能是并发的。例如，如图8所示，终端通过3.5G载波在3.5G载波对应的时隙4和时隙9上进行发送，终端通过2.6G载波在2.6G载波对应的时隙3上进行发送，终端通过1.8G载波在1.8G载波对应的时隙0至时隙4上进行发送，那么3.5G载波和2.6G载波是TDM方式进行发送的，3.5G载波和1.8G载波在3.5G对应的时隙4和时隙9上是并发的，2.6G载波和1.8G载波在2.6G对应的时隙3上是并发的。
14、多个载波并发时，多个载波中每个载波支持的射频通道能力
可以理解，至少存在一个时刻，多个载波并发，在该时刻中，每个载波支持的射频通道能力为多个载波并发时，该载波支持的射频通道能力。
需要说明的是，终端在上报多个载波并发时，每个载波支持的射频通道能力，网络设备和终端可以不区分该多个载波什么时候并发，在所有时域资源上都按照各个载波并发时支持的射频通道能力进行调度。
例如，在t1时刻，载波1和载波2是并发的，载波1支持1T，载波2支持1T，那么载波1和载波2并发时，载波1支持1T，载波2支持1T。网络设备可以在所有时域资源上，都按照载波1支持1T，载波2支持1T进行调度。
目前，在一些方案中，网络设备可以按照满足较长时间内各个载波的射频通道能力向终端发送一个或多个载波的射频通道能力，终端根据该一个或多个载波的射频通道能力在该一个或多个载波上进行上行发送，会限制终端的上行发送能力。例如，参见图5，载波1支持射频通道1和射频通道2，载波2支持射频通道2。载波1为2.6G载波，载波2为3.5G载波，2.6G载波和3.5G载波的时隙配置参见图6，若网络设备在3.5G载波的时隙3指示终端在3.5G载波采用1T，指示终端在2.6G载波采用1T，终端在3.5G载波的时隙4和时隙9采用1T进行上行发送，在2.6G载波的时隙2和时隙3采用1T进行上行发送。 而实际上，由于2.6G载波支持2T，终端在2.6G载波的时隙3可以采用2T进行上行发送，由此可知，现有的方法限制了终端的上行发送能力。
为了提高终端的上行发送能力，本申请实施例提供了以下实施例一至实施例三所述的方法，实施例一和实施例三中，网络设备可以灵活的指示终端在一个或多个载波上的射频通道能力，实施例二中，终端可以根据网络设备在各个载波上的上行调度情况确定在一个或多个载波上的射频通道能力，实施例一至实施例三均可以灵活的调整终端在一个或多个载波上的射频通道能力，提高终端的上行发送能力。
本申请实施例提供的方法可以应用于任何多载波场景。该情况下，终端可以位于多个载波的覆盖重叠区域中，终端可以选择不同的载波进行上行发送。多载波场景包括但不限于上述任何一种DC场景或CA场景或SUL场景等。
本申请实施例中的载波可以为FDD载波，也可以为TDD载波。
本申请实施例中的载波例如可以为3.5G载波、2.6G载波、1.8G载波、900兆(M)载波等。
实施例一
实施例一提供了一种射频能力配置方法，如图9所示，包括：
901、终端向网络设备发送终端的能力信息。
相应的，网络设备从终端接收终端的能力信息。
该能力信息可以包括多个射频能力。

可选的，当该载波与其他载波并发时，上报的可能是一个频段组合下的能力，例如：频段组合：频段A+频段B，载波A 1T，载波B 1T。载波A和载波B的时域资源存在重叠，终端和网络设备可以将该频段组合的能力认为是并发方式下的载波A和载波B的能力。
示例1，假设N个载波为载波A和载波B，参见图10，载波A和载波B均支持射频通道1和射频通道2。那么在载波A单发时，载波A最多支持2T。在载波B单发时，载波B最多支持2T。在载波A和载波B并发时，载波A和载波B均支持1T。该情况下，终端的能力信息中包括的信息可参见表1。

示例2，假设N个载波为载波A、载波B和载波C，参见图11，载波A支持射频通道1、射频通道2和射频通道3，载波B和载波C均支持射频通道2和射频通道3。那么在载波A单发时，载波A最多支持3T。在载波B单发时，载波B最多支持2T。在载波C单发时，载波C最多支持2T。在载波A和载波B并发时，载波A最多支持2T，载波B最多支持1T，或者，载波A最多支持1T，载波B最多支持2T。在载波A和载波C并发时，载波A最多支持2T，载波C最多支持1T，或者，载波A最多支持1T，载波C最多支持2T。在载波B和载波C并发时，载波B最多支持1T，载波C最多支持1T。在载波A、载波B和载波C并发时，载波A最多支持1T，载波B最多支持1T，载波C最多支持1T。该情况下，终端的能力信息中包括的信息可参见表2。

当实施例一提供的方法应用于DC场景中时，网络设备可以为主网络设备，也可以为辅网络设备。第一载波可以为终端与主网络设备之间的载波，也可以为终端与辅网络设备之间的载波。
步骤901为可选步骤。例如，终端和网络设备可以预配置终端的能力，此时可以不用终端上报给网络设备。
可选的，终端的能力信息中还包括终端是否支持射频能力动态切换。若终端支持射频能力动态切换，终端可以在一个载波的多个射频能力之间进行切换。
902、网络设备向终端发送配置信息，配置信息用于配置第一载波的多个射频能力，多个射频能力与多个索引一一对应。
相应的，终端从网络设备接收配置信息。
可选的，第一载波的多个射频能力包括第一载波单发时第一载波的射频能力。
可选的，第一载波的多个射频能力包括第一载波与除第一载波之外的一个或多个载波并发时第一载波的射频能力。其中，当一个载波与不同的载波并发时，该载波的射频能力也可以不同，例如，参见上述表2，载波A与载波B并发时载波A支持2T，载波A与载波B和载波C并发时，载波A支持1T。由此可知，第一载波与除第一载波之外的一个或多个载波并发时第一载波的射频能力可以有一个，也可以有多个。
可选的，配置信息用于配置N′(N′为大于0的整数)个载波的射频能力，N′个载波中至少一个载波被配置多个射频能力，N′个载波中的每个载波的每个射频能力对应一个索引。一个载波的多个射频能力对应的索引均不同，不同载波的射频能力对应的索引可以相同也可以不同。其中，N′个载波包括第一载波，N′个载波属于N个载波。N′可以与N相同，也可以小于N，本申请实施例中以N＝N′为例对本申请实施例提供的方法作示例性说明。
也就是说，配置信息除了用于配置第一载波的多个射频能力之外，还用于配置N′个载波中的除第一载波之外的每个载波的一个或多个射频能力。其中，任意一个载波的多个射频能力可以包括该载波单发时该载波的射频能力，还可以包括该载波与除该载波之外的一个或多个载波并发时该载波的射频能力。
可选的，配置信息携带在无线资源控制(radio resource control，简称RRC)信令中。示例性的，针对一个载波，网络设备可以通过3GPP技术规范(technical specification，TS)38.331版本(version，V)15.5.0的章节6.3.2中的信元上行配置列表(“uplinkConfigList”)的序列(sequence)中包括的信元上行配置标识(“UplinkConfig–Id”)配置该载波的一种或多种射频能力。进一步的，若该载波具有SUL，还可以通过信元辅助上行列表(“supplementaryUplinkList”)的sequence中包括的信元“UplinkConfig–Id”配置该SUL的一种或多种射频能力。其中，“UplinkConfig–Id”中Id的一个取值用于配置一种射频能力。示例性的，“uplinkConfigList”中包含的信息可以为：

Figure PCTCN2020093002-appb-000002
在步骤901存在的情况下，步骤902在具体实现时可以包括：网络设备根据终端的能力信息向终端发送配置信息。具体的，网络设备可以先根据终端上报的能力信息确定每个载波单发时的射频能力和每个载波与不同载波并发时的射频能力，再确定每个载波共有几个射频能力。
在步骤901不存在的情况下，配置信息可以预先配置在网络设备中，或网络设备从其他设备直接获取到的。
基于上述示例1，以射频能力仅包括射频通道能力为例，若N′个载波为载波A和载波B，载波A支持2T和1T，载波B支持2T和1T，则配置信息配置的N′个载波的射频通道能力，以及射频通道能力对应的索引可参见表3。

基于上述示例2，以射频能力仅包括射频通道能力为例，若N′个载波为载波A、载波B和载波C，载波A支持3T、2T和1T，载波B支持2T和1T，载波C支持2T和1T，则配置信息配置的N′个载波的射频通道能力，以及射频通道能力对应的索引可参见表4。
表4
Figure PCTCN2020093002-appb-000004
可选的，网络设备可以在终端支持射频能力动态切换的情况下执行步骤902。
903、网络设备向终端发送第一指示信息，第一指示信息用于指示第一索引，第一索引为多个索引中的一个索引。相应的，终端从网络设备接收第一指示信息。
可选的，第一指示信息用于指示n1个索引，n1个索引对应N′个载波中的n1个载波，n1个索引包括第一索引，n1为大于0小于等于N′的整数。也就是说，第一指示信息除了用于指示第一索引之外，还用于指示n1个索引中的除第一索引之外的其他索引。
示例性的，参见表4，第一指示信息可以指示载波A对应的索引2和载波B对应的索引1。第一索引可以为载波A对应的索引2或载波B对应的索引1。
可选的，第一指示信息携带在媒介接入控制(media access control，MAC)控制元素(controlelement，CE)信令或下行控制信息(downlink control information，DCI)中。
示例性的，MAC CE或DCI中可以新增一个字段用于指示载波的索引。该字段可以包括1个或多个比特(bit)。示例性的，该字段的名称可以为上行配置指示 (uplinkconfigindication)。
可选的，步骤903在具体实现时可以包括：903-a、网络设备根据第一载波和除第一载波之外的一个或多个载波的上行调度情况向终端发送第一指示信息。
步骤903-a在具体实现时，网络设备可以根据第一载波和一个或多个载波的上行调度的时域资源的位置，确定第一载波单发，或者，确定第一载波与一个或多个载波并发。具体的，网络设备可以根据第一载波和一个或多个载波的上行调度的时域资源的重叠情况，确定第一载波单发，或者，确定第一载波与哪些载波并发。
针对第一载波的一段上行调度的时域资源(例如，多个上行时隙或一个上行时隙或若干个上行符号)，网络设备确定第一载波单发还是与一个或多个载波并发的方法可以为：若该段上行调度的时域资源不与任意一个载波的上行调度的时域资源重叠，网络设备可以确定在第一载波的该段上行调度的时域资源上，终端在第一载波上单发。若该段上行调度的时域资源与一个或多个其他载波(例如，2个载波)的上行调度的时域资源重叠，那么，网络设备可以确定在第一载波的该段上行调度的时域资源上，终端在第一载波上与该一个或多个其他载波(例如，2个载波)中的一个或多个载波(例如，2个载波中的1个载波或2个载波)并发。
网络设备在确定第一载波单发，或者，确定第一载波与哪些载波并发之后，再确定指示第一载波的哪个射频能力。
示例性的，当网络设备确定第一载波单发时，第一指示信息指示第一载波单发时，第一载波的射频能力，即第一索引对应的射频能力为第一载波单发时，第一载波的射频能力。
示例性的，当网络设备确定第一载波与一个或多个载波并发时，第一指示信息指示第一载波与一个或多个载波并发时，第一载波的射频能力，即第一索引对应的射频能力为第一载波与一个或多个载波并发时，第一载波的射频能力。进一步的，若第一载波与不同载波并发时第一载波的射频能力有多种，当网络设备确定第一载波与一个或多个载波并发时，第一指示信息具体指示第一载波的哪个射频能力取决于该一个或多个载波为哪些载波。此时网络设备可以根据终端上报的能力信息确定第一载波的射频能力。
示例性的，基于表2所示的示例，若网络设备在载波1、载波2和载波3上的上行调度的时域资源如图12所示。网络设备确定并指示终端在载波3的上行时隙0上载波3单发，载波3单发时的射频通道能力为2T。网络设备确定并指示终端在载波1的时隙4(即载波2和载波3的上行时隙2的前半个时隙)上载波1、载波2和载波3并发，载波1、载波2和载波3并发时载波1、载波2和载波3的射频通道能力均为1T。网络设备确定并指示终端在载波2和载波3的上行时隙2的后半个时隙上载波2和载波3并发，载波2和载波3并发时载波2和载波3的射频通道能力均为1T。
其中，网络设备确定第一指示信息指示的n1个索引中的每个索引的过程与第一索引类似。
904、终端以第一索引对应的射频能力在第一载波上进行上行发送。
可选的，针对n1个索引中除第一索引之外的每个索引，终端还以该索引对应的射频能力在该索引对应的载波上进行上行发送。
示例性的，参见表4，若第一索引为载波A对应的索引2，那么终端以1T在载波A上进行上行发送。若第一指示信息还指示了载波B对应的索引1，那么终端还以1T在载波B上进 行上行发送。
步骤904为可选步骤。
905、网络设备向终端发送第二指示信息，第二指示信息用于指示第二索引，第二索引为多个索引中的一个索引。相应的，终端从网络设备接收第二指示信息。
可选的，第二指示信息用于指示n2个索引，n2个索引对应N′个载波中的n2个载波，n2个索引包括第二索引，n2为大于0小于等于N′的整数。也就是说，第二指示信息除了用于指示第二索引之外，还用于指示n2个索引中除第二索引之外的其他索引。
其中，第一索引和第二索引可以相同，也可以不同，本申请实施例对此不作具体限定。网络设备确定第二指示信息指示的n2个索引中的每个索引的过程与第一索引类似，不再赘述。
示例性的，参见表4，第二指示信息可以指示载波A对应的索引1和载波B对应的索引1。第二索引可以为载波A对应的索引1或载波B对应的索引1。
可选的，第二指示信息携带在MAC CE信令或DCI中。
可选的，第一指示信息和第二指示信息可以均携带在MAC CE信令中，也可以均携带在DCI中，也可以一个携带在MAC CE信令中，另一个携带在DCI中。
实施例一是以第一载波为例对网络设备配置载波采用的射频能力的过程作示例性说明的，因此，第一指示信息和第二指示信息中均包含第一载波的射频能力对应的索引。在实际实现时，网络设备发送的两个指示信息指示的索引对应的载波之间可以有相同的载波，也可以没有相同的载波，本申请实施例对此不作具体限制。
步骤905为可选步骤。
906、终端以第二索引对应的射频能力在第一载波上进行上行发送。
可选的，针对n2个索引中除第二索引之外的每个索引，终端还以该索引对应的射频能力在该索引对应的载波上进行上行发送。
示例性的，参见表4，若第二索引为载波A对应的索引1，那么终端以2T在载波A上进行上行发送。若第二指示信息还指示了载波B对应的索引1，那么终端还以1T在载波B上进行上行发送。
步骤906为可选步骤。
实施例一提供的方法，针对一个载波，网络设备可以为终端配置该载波的、与多个索引一一对应的多个射频能力，再通过指示信息指示一个索引，终端通过该索引即可确定采用多个射频能力中的哪个射频能力。网络设备通过指示索引，可以灵活的指示载波的射频能力，从而在不同的时域资源上，网络设备可以根据终端的载波的射频能力为终端指示载波的射频能力，提高终端的上行发送能力。
实施例二
实施例二提供了一种射频能力配置方法，与实施例一的区别主要在于，网络设备为终端配置第一载波的多个射频能力之后，终端可以根据网络设备在第一载波和除第一载波之外的一个或多个载波的上行调度情况选择第一载波的多个射频能力中的一个射频能力进行上行发送，而不需要网络设备为终端指示终端在第一载波上采用的射频能力。
如图13所示，实施例二提供的射频能力配置方法包括：
1301、终端向网络设备发送终端的能力信息。
相应的，网络设备从终端接收终端的能力信息。
可选的，终端的能力信息中包括第一载波单发时第一载波的射频能力的信息。
可选的，终端的能力信息中还包括第一载波与除第一载波之外的一个或多个载波并发时第一载波的射频能力的信息。
可选的，终端的能力信息中还包括第一载波与除第一载波之外的一个或多个载波并发时该一个或多个载波中的每个载波的射频能力的信息。
可以理解，终端的能力信息中包括N(N为大于1的整数)个载波中的一个或多个载波中的每个载波单发时的射频能力的信息，以及N个载波中的多个载波并发时该多个载波中的每个载波的射频能力的信息。N个载波为终端的部分或全部载波。N个载波包括第一载波。
也就是说，终端的能力信息除了包括第一载波单发时第一载波的射频能力的信息，和，第一载波与除第一载波之外的一个或多个载波并发时第一载波的射频能力的信息和该一个或多个载波中的每个载波的射频能力的信息，还包括N个载波中除第一载波之外的一个或多个载波中的每个载波单发时的射频能力的信息，和/或，N个载波中的不包括第一载波在内的多个载波并发时该多个载波中的每个载波的射频能力的信息。
关于终端的能力信息的具体示例可参见上述步骤901的相关描述，在此不再赘述。
当实施例二提供的方法应用于DC场景中时，网络设备可以为主网络设备，也可以为辅网络设备。第一载波可以为终端与主网络设备之间的载波，也可以为终端与辅网络设备之间的载波。
步骤1301为可选步骤。例如，终端和网络设备可以预配置终端的能力，此时可以不用终端上报给网络设备。
可选的，终端的能力信息中还包括终端是否支持射频能力动态切换。若终端支持射频能力动态切换，终端可以在一个载波的多个射频能力之间进行切换。
1302、网络设备获取配置信息，配置信息用于配置第一载波的多个射频能力。
可选的，第一载波的多个射频能力与多个索引一一对应。
可选的，第一载波的多个射频能力包括第一载波单发时第一载波的射频能力。
可选的，第一载波的多个射频能力包括第一载波与除第一载波之外的一个或多个载波并发时第一载波的射频能力。其中，当一个载波与不同的载波并发时，该载波的射频能力也可以不同，例如，参见上述表2，载波A与载波B并发时载波A支持2T，载波A与载波B和载波C并发时，载波A支持1T。由此可知，第一载波与除第一载波之外的一个或多个载波并发时第一载波的射频能力可以有一个，也可以有多个。
可选的，配置信息用于配置N′(N′为大于0的整数)个载波的射频能力，N′个载波中至少一个载波被配置多个射频能力，N′个载波中的每个载波的每个射频能力对应一个索引。一个载波的多个射频能力对应的索引均不同，不同载波的射频能力对应的索引可以相同也可以不同。其中，N′个载波包括第一载波，N′个载波属于N个载波。N′可以与N相同，也可以小于N，本申请实施例中以N＝N′为例对本申请实施例提供的方法作示例性说明。
也就是说，配置信息除了用于配置第一载波的多个射频能力之外，还用于配置N′个载波中的除第一载波之外的每个载波的一个或多个射频能力。其中，任意一个载波的多个射频能力可以包括该载波单发时该载波的射频能力，还可以包括该载波与除该载波之外的一个或多个载波并发时该载波的射频能力。
在步骤1301存在的情况下，步骤1302在具体实现时，网络设备可以根据终端的能力信息获取配置信息。具体的，网络设备可以先根据终端上报的能力信息确定每个载波单发时的射频能力和每个载波与不同载波并发时的射频能力，再确定每个载波共有几个射频能力。具体示例可参见上述步骤902的相关描述。
在步骤1301不存在的情况下，配置信息可以预先配置在网络设备中，或网络设备从其他设备直接获取到的。
步骤1302为可选步骤。
1303、网络设备向终端发送配置信息。相应的，终端从网络设备接收配置信息。
可选的，配置信息携带在RRC信令中。具体示例可参见上述步骤902的相关描述，在此不再赘述。
可选的，网络设备可以在终端支持射频能力动态切换的情况下执行步骤1302和步骤1303。
1304、终端根据第一载波和除第一载波之外的一个或多个载波的上行调度情况在第一载波上以多个射频能力中的一个射频能力进行上行发送。
步骤1304在具体实现时，终端可以根据第一载波和一个或多个载波的上行调度的时域资源的位置确定第一载波单发，或者，确定第一载波与一个或多个载波并发。具体的，终端可以根据第一载波和一个或多个载波的上行调度的时域资源的重叠情况，确定第一载波单发，或者，确定第一载波与哪些载波并发。
具体的，终端可以根据网络设备发送的调度不同载波上的上行数据的DCI确定不同载波上的上行调度的时域资源。针对第一载波的一段上行调度的时域资源，终端确定第一载波单发还是与一个或多个载波并发的方法与网络设备类似，具体可参见实施例一中的相关描述，在此不再赘述。
终端在确定第一载波单发，或者，确定第一载波与哪些载波并发之后，再确定在第一载波上采用的射频能力。
示例性的，当终端确定第一载波单发，终端在第一载波上以第一载波单发时第一载波的射频能力进行上行发送。
示例性的，当终端确定第一载波与一个或多个载波并发时，终端在第一载波上以与一个或多个载波并发时第一载波的射频能力进行上行发送。进一步的，若第一载波与不同载波并发时第一载波的射频能力有多种，当终端确定第一载波与一个或多个载波并发后，确定采用第一载波的哪个射频能力取决于该一个或多个载波为哪些载波。
具体的，配置信息中配置的一个载波的一个射频能力中的射频通道能力和其他射频能力存在对应关系。由于终端知道一个载波单发时的射频通道能力和一个载波与不同载波并发时的射频通道能力。因此，终端可以先确定一个载波单发或并发时的射频通道能力，再根据射频通道能力确定其他射频能力，从而确定在该载波上采用的射频能力。
示例性的，基于示例1，载波A和载波B分别有两个射频能力，记为射频能力1和射频能力2。载波A和载波B的射频通道能力和其他射频能力可以参见表5。其中，载波A的射频通道能力为2T的射频通道能力对应其他射频能力1，载波B的射频通道能力为2T的射频通道能力对应其他射频能力2，载波A的射频通道能力为1T的射频通道能力对应其他射频能力3，载波B的射频通道能力为1T的射频通道能力对应其他射频能力4。

本申请上述实施例中的各个方案在不矛盾的前提下，均可以进行结合。
需要说明的是，在上述各个实施例中的不同载波之间可以是异步的，即不同载波的时隙的起始符号是不对齐的。例如，参见图15，载波1、载波2和载波3的时隙的起始符号是不对齐的，载波3和载波4的时隙的起始符号是对齐的。
该情况下，终端可以测量系统帧号和帧定时差异(即SFTD，SFTD为3GPP TS 38.215 V15.4.0的章节5.1.14中的信元“SFN and frame timing difference”，SFN是指系统帧号(system frame number))和上行定时提前(timing advance，TA)信息，并向网络设备发送SFTD和上行TA信息。网络设备可以根据终端上报的SFTD和/或上行TA信息获取不同载波的时隙之间的时延差异。该情况下，若多个载波的上行时域资源重叠，当终端仅在一个载波上进行上行发送时，在其他载波上网络设备需要进行符号级调度避让，避免终端在多个载波的重叠的上行时域资源上并发。
