背景技术
随着智能终端用户的不断增长、用户业务量和数据吞吐量的不断增加，其对通信速率提出了更高的要求，为了满足更大的下行和上行峰值速率的要求，需要提供更大的传输带宽，由于大带宽的连续频谱的稀缺，4G长期演进(long term evolution，LTE)***提出了载波聚合(carrier aggregation，CA)的解决方案。
工作规划16(release 16,R16)提出了一种新的上行模式，即如果终端设备支持2个上行载波，则终端设备能够在这两个载波上进行射频链的切换，提高射频链的利用率。
在工作规划15(release 15,R15)中，终端设备需要向网络设备上报终端设备所支持的频段组合列表(list)，而在R16中，对于支持动态射频链切换的终端设备，该协议设计了一种新的频段组合列表(list)，即终端设备需要在新的频段组合列表(list)中上报所支持的动态射频链切换相关的频段信息。

在图1所示的通信场景的示意图中，该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、终端、无线通信设备、用户代理或用户装置。终端设备还可以是蜂窝电话、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、个人数字处理(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网络中的终端设备或者演进的公用陆地移动通信网络(public land mobile network，PLMN)中的终端设备等，本申请实施例对此并不限定。
在图1所示的通信场景的示意图中，该网络设备可以是用于与终端设备通信的设备，该网络设备可以是全球移动通讯(global system of mobile communication，GSM)***或码分多址(code division multiple access，CDMA)中的基站(base transceiver station，BTS)，也可以是宽带码分多址(wide频段code division multiple access，WCDMA)***中的基站(nodeB，NB)，还可以是LTE***中的演进型基站(evolutional nodeB，eNB或eNodeB)，还可以是云无线接入网络(cloud radio access network，CRAN)场景下的无线控制器，或者该网络设备可以为中继站、接入点、车载设备、可穿戴设备以及G网络中的网络设备或者演进的PLMN网络中的网络设备等，本申请实施例并不限定。
下文将对本申请实施例所涉及的一些概念做出简洁描述。
载波聚合是指将至少两个载波单元(componentcarrier，CC)聚合在一起以便支持更大的传输带宽。
示例性地，当终端设备被配置多个小区(cell)时，且每个cell包括一个下行载波和0～2个上行载波，则终端设备可以激活多个cell中的部分cell，但是部分终端设备的上行能力有限，最多只能配置和激活两个上行载波。
当终端设备被配置两个上行载波的CA模式时，则终端设备可以在被配置的两个载波间进行时分发送，且终端设备总共有两个可同时发送的射频链。此时，这两个射频链可以在这两个载波上进行动态分配，例如，载波X上采用射频链1发送，载波Y上采用射频链2发送，抑或，载波X不采用射频链1发送，且载波Y上采用射频链1和射频链2发送。
终端设备能够向网络设备上报一个或多个上行可同时发送的频段组合，该组合表示终端设备支持该组合内的频段上的同时上行发送。
发射通道(transmitter，Tx)是一个物理概念，也可以称为射频(radio frequency，RF)，在本申请中，发射通道均简称为射频链。
可选的，本申请中射频链也可以替换为Tx、天线、射频、发射通道、发送端口、接收通道或者它们的任意组合。
可选的，本申请中，终端设备在一个载波的射频链数目是X，意味着终端设备在这个载波支持的天线端口数小于或等于X的上行传输，不支持天线端口数大于X的上行传输，也意味着终端设备的操作状态(或终端设备的状态)是在这个载波支持的天线端口数小于或等于X的上行传输，不支持天线端口数大于X的上行传输，其中X为正整数。
在本申请中，射频链可以是按照如下的方式工作，但不限于如下方式：射频链可接收来自基带芯片的基带信号，对基带信号进行射频处理(如上变频、放大和滤波)以得到射频信号，并最终通过天线将该射频信号辐射到空间中。具体地，射频链可以包括天线开关，天线调谐器，低噪声放大器(low noise amplifier，LNA)，功率放大器(power amplifier，PA)，混频器(mixer)，本地振荡器(local oscillator，LO)、滤波器(filter)等电子器 件，这些电子器件可以根据需要集成到一个或多个芯片中。天线有时也可以认为是射频链的一部分。
天线端口(port)是一个逻辑概念。在实际发送信号时，终端设备会将天线端口映射到对应的射频链中。网络设备在调度终端设备传输数据时，可以明确指示终端设备传输数据时使用的天线端口的端口号。
可选的，天线端口可以简称端口。
R16提出了一种新的上行模式，即，如果终端设备支持两个上行载波，则终端设备可以在这两个载波上进行Tx切换，从而能够提高射频链的利用率。
对于支持在两个上行载波上进行Tx切换且该两个上行载波包括两个Tx的终端设备，协议通过表1对终端设备在这两个上行载波上的发送行为进行了定义。
可选的，Tx切换可以替换为上行Tx切换，也可以替换为动态上行Tx切换，也可以替换为上行切换，也可以替换为动态Tx切换，本申请对此不做限定。
具体如表1所示：
表1
Figure PCTCN2022085579-appb-000001
其中，载波X和Y分别表示两个上行载波，Tx表示射频链。
其中，case 1表示终端设备在载波X上有1个射频链，在载波Y上有1个射频链。case2表示终端设备在载波X没有射频链，在载波Y上有2个射频链。
由表1可以看出，终端设备在载波X上最大支持1个Tx，在载波Y上最大支持2个Tx。
终端设备可以在这两个case之间进行切换，即可以把1个Tx在两个载波之间进行切换，而这两个case之间切换需要切换时间。这个切换时间可以称之为上行切换时间(uplink switching gap)。
终端设备在uplink switching gap内不希望在两个载波的任何一个上面进行传输。
协议不直接指示终端设备在载波上进行Tx切换，而是通过终端设备在载波上的上行传输的端口数来间接指示终端设备进行Tx切换，进而确定本次上行传输是否需要进行射频链的切换，即是否存在切换时间。
表2示出了射频链与上行传输端口的映射关系。
表2
Figure PCTCN2022085579-appb-000002
表2示出了支持切换模式(switchedUL)的上行CA的终端设备的Tx和上行传输端口的映射关系。
在case1，即载波X有1个Tx，载波Y有1个Tx的情况下，终端设备可以在载波X发送1个port的上行传输同时在载波Y没有上行传输(1P+0P)。
在case2，即载波X没有Tx，载波Y有2个Tx的情况下，终端设备可以在载波Y发送2个port的上行传输同时在载波X没有上行传输(0P+2P)，在载波Y发送1个port的上行传输同时在载波X没有上行传输(0P+1P)。
协议依据终端设备在两个载波上的即将发送的上行传输的port数和上一次上行传输的port数来判断是否需要切换时间。
示例性地，当终端设备即将在一个载波进行1port的传输，且终端设备之前的传输为在另一个载波的1port传输，即表示，从case1的1P+0P切换到case2的0P+1P，此时终端设备需要进行射频链切换，在uplink switching gap内不希望在两个载波的任何一个上面进行传输。
表3示出了支持并发模式(dualUL)的上行CA的终端设备的Tx和上行传输端口的映射关系。
具体如表3所示：
表3
Figure PCTCN2022085579-appb-000003
在case1，即载波X有1个Tx，载波Y有1个Tx的情况下，终端设备可以在载波X发送1port的上行传输同时在载波Y没有上行传输(1P+0P)，在载波X发送1port的上行传输同时在载波Y发送1port的上行传输(1P+1P)，在载波Y发送1port的上行传输同时在载波X没有上行传输(0P+1P)。
换言之，终端设备的操作状态是在载波X支持1port上行传输，或者说终端设备的操作状态是在载波Y支持1port上行传输，或者说终端设备的操作状态是在载波X支持1port上行传输且同时在载波Y支持1port上行传输，或者说终端设备的操作状态是在载波X不支持2port上行传输且同时在载波Y不支持2port上行传输，或者说终端设备的操作状态是在载波X不支持2port上行传输，或者说终端设备的操作状态是在载波Y不支持2port上行传输。
在case2，即载波X没有Tx，载波Y有2个Tx的情况下，终端设备可以在载波Y发送2个port的上行传输同时在载波X没有上行传输(0P+2P)，在载波Y发送1个port的上行传输同时在载波X没有上行传输(0P+1P)。
换言之，终端设备的操作状态是在载波Y上支持2port或1port上行传输，在载波X上不支持上行传输。
由表3可以看出，case1和case2均有0P+1P的状态。如果终端设备即将在载波Y进 行1port传输，同时在载波X上没有上行传输，那么终端设备的Tx状态是上一次上行传输的Tx状态。即终端设备的Tx状态不发生改变，也就是终端设备不需要切换时间。
协议依据终端设备在两个载波上的即将发送的上行传输的port数，上一次上行传输的port数，和所支持的上行传输port数或终端设备的操作状态来判断是否需要切换时间。
示例性地，即将在一个载波发送2port进行传输，之前的传输为在这个载波的1port传输，且终端设备的操作状态是在这个载波上不支持2port传输，即表示，从case1的0P+1P切换到case2的0P+2P，此时终端设备需要进行Tx切换，且在uplink switching gap内不希望在两个载波的任何一个上面进行传输。
例如，即将在一个载波发送1port传输，之前的传输为在另外一个载波的1port传输，且终端设备的操作状态是在这个载波上支持2port传输，即表示，从case2的0P+1P切换到case1的1P+XP，X的取值可以为0或者1，此时终端设备需要进行Tx切换，在uplink switching gap内不希望在两个载波的任何一个上面进行传输。
此外，无论是支持switchedUL的终端设备还是支持dualUL的终端设备在符合以下两个条件下都会有切换时间：
条件1：即将在一个载波发送2port传输，之前的传输为在另一个载波的1port上行传输(case1的1P+0P切换到case2的0P+2P)，此时终端设备需要进行射频链切换，在uplink switching gap内不希望在两个载波的任何一个上面进行传输。
条件2：即将在一个载波发送1port传输，之前的传输为在另一个载波的2port上行传输(case2的0P+2P切换到case1的1P+0P)，此时终端设备需要进行射频链切换，在uplink switching gap内不希望在两个载波的任何一个上面进行传输。
另外，如果终端设备不进行上次传输，那么终端设备的Tx状态是上一次上行传输的Tx状态。即终端设备的Tx状态不发生改变。
终端设备在同一个case内的不同port的上行发送之间，不需要切换，所以不需要切换时间。
由于载波X和载波Y上支持的最大port数不一样，所以网络设备给终端设备配置载波时需要指定该载波为载波X还是载波Y，从而便于进行区分。
上文已对本申请实施例所涉及的相关概念进行了简洁的描述。
在R16中，终端设备可以向网络设备中上报多个频段集合，且对网络设备为终端设备配置的载波集合的数量也没有限制，但是当网络设备为终端设备配置至少两个载波集合，且不清楚为终端设备配置的至少两个载波集合之间的关系时，会影响网络设备对终端设备的调度。其中，网络设备给终端设备配置的可进行射频链切换的载波依据的是终端设备给网络设备上报的频段组合。
一种可能情况是，载波和频段可以全部或部分地互相替换，载波集合和频段集合也可以全部或部分地互相替换。
一种可能情况是，频段可以全部或部分地替换为属于该频段的载波。
可选的，一个频段集合可以包括一个或多个频段，载波集合中的载波也可以替换为频段集合中的频段。
一种可能情况是，一个频段包括一个或多个载波。
一种可能情况是，频段集合中的多个频段可有相同的频段，也可以有不同的频段。
一种可能情况是，一个频段集合中的载波包括这个频段集合中的至少一个频段上的至少一个载波。
鉴于上述技术问题，本申请提供了一种能力上报的方法，能够解决当网络设备为终端设备配置至少两个载波集合时，且不清楚为终端设备配置的至少两个载波集合之间的关系时，使能网络设备调度终端设备。
下文将结合图2对本申请提供的一种信息发送和接收的方法做出描述。
图2示出了本申请提供的一种信息发送和接收的方法，该方法的执行主体是终端设备与网络设备，具体如图2所示。
S210，终端设备确定第一信息，该第一信息包括第一信元和第二信元，第一信元指示至少两个频段集合，该至少两个频段集合中第一频段集合包括至少一个频段，第二信元指示该至少两个频段集合中第二频段集合与第一频段集合之间的第一关系，该第一关系包括：切换或者并发。
S220，终端设备向网络设备发送第一信息。
S230，网络设备接收来自终端设备的第一信息。
S240，网络设备配置M个载波集合，该M个载波集合中的载波属于该至少两个频段集合中的至少一个频段，该M个载波集合中第二载波集合包括至少一个载波，该M个载波集合中第三载波集合与第二载波集合之间的关系为第二频段集合与第一频段集合之间的第一关系，其中，第二载波集合为第一频段集合对应的载波集合，第三载波集合为第二频段集合对应的载波集合，M大于或等于2，M为正整数。
应理解，M个载波集合中的第二载波集合可以指代该M个载波集合中的任意一个载波集合，且该第二载波集合包括至少一个载波，且第三载波集合也包括至少一个载波，且与第二载波结集合之间的关系与该第一关系保持一致。
应理解，一个载波集合为一个频段集合对应的(或所属的)载波集合，意味着，这个载波集合中的所有载波均属于这个频段集合中的至少一个频段。
例如，如果第二载波集合包括载波1和载波2，第一频段集合至少包括频段A和频段B，且载波1属于频段A，载波2属于频段B，那么第二载波集合为第一频段集合对应的(或所属的)载波集合。
例如，如果第二载波集合包括载波1和载波2，第一频段集合至少包括频段A，且载波1属于频段A，载波2属于频段A，那么第二载波集合为第一频段集合对应的(或所属的)载波集合。
例如，如果第二载波集合包括载波1、载波2和载波3，第一频段集合至少包括频段A、频段B和频段C，且载波1属于频段A，载波2属于频段A，载波3属于频段B，那么第二载波集合为第一频段集合对应的(或所属的)载波集合。
例如，如果第二载波集合包括载波1和载波2，第三载波集合包括载波3和载波4，第一频段集合包括频段A和频段B，第二频段集合包括频段C和频段D，且载波1属于频段A，载波2属于频段B，载波3属于频段C，载波4属于频段D，且第一频段集合和第二频段集合和第二频段集合之间的第一关系是切换，那么第二载波集合与第三载波集合之间的关系为切换。
可选的，两个载波集合之间的关系是并发，也就意味着，网络设备在调度或者配置终 端设备在一个载波集合中的至少一个载波进行传输的同时，也可以调度或者配置终端设备在另外一个载波集合中的至少一个载波上进行传输。
可选的，两个载波集合之间的关系是切换，也就意味着，网络设备在调度或者配置终端设备在一个载波集合中的至少一个载波进行传输的同时，不能调度或者配置终端设备在另外一个载波集合中的至少一个载波上进行传输。
可选地，网络设备给终端设备的配置信息遵循第一信息。
可选的，终端设备上报的至少两个频段集合中的至少一个频段集合为终端设备支持的可以进行Tx切换的频段集合。
可选地，终端设备在网络设备配置的M个载波集合中的至少一个载波集合的载波上可以进行Tx切换。
可选的，如果没有上报第二信元，那么第一频段集合和第二频段集合之间的关系可以默认是切换或并发。
可选的，第二信元是强制上报的。
通过上述技术方案，本申请能够使能网络设备获知终端设备在至少一个载波集合上进行上行Tx切换的支持情况，使得网络设备在给终端设备配置至少一个载波集合时能够正常调度终端设备。
应理解，在前述步骤S210中，该第一信息可以是用于上行射频链切换的频段组合，或者包含支持上行射频链切换的频段组合，其用于指示终端设备向网络设备上报的至少一个频段组合，其中一个频段组合中包括至少一个频段。
其中，该第一信息可以包括第一信元，示例性地，该第一信元可以是上行射频链切换频段集合，其用于指示至少一个频段集合，其中一个频段集合包括至少两个频段。
为便于描述，本申请以一个频段组合包括四个频段、一个频段集合包括2个频段为例，描述本申请的技术方案，但是该描述方式不具备限定作用。
需要说明的是，当终端设备上报的第一信息中已经确定该第一频段集合与第二频段集合的第一关系时，该第一频段集合或者第二频段集合可以仅包括一个频段。
示例性地，当终端设备上报了两个频段集合，分别是频段集合{A，B}和频段集合{C}，则该两个频段集合之间的关系可以是同时发送，即支持并发模式，或者时分发送，即切换模式。因此，当两个频段集合之间的关系确定后，则两个频段集合中的任一个频段集合可以仅包括一个频段。
示例性地，当终端设备上报的至少一个频段集合中的一个频段集合与其他任何一个频段集合之间的关系均没有确定或者明确时，则该频段集合中需要包括至少两个频段。
可选的，这至少两个频段可以相同，也可以不同。
可选的，当终端设备上报的一个频段集合中的一个频段支持至少两个载波，且UE支持在前述至少两个载波上进行射频链切换，则频段集合可以仅包括一个频段。
应理解，至少一个频段集合中的所有频段均属于一个频段组合中，且一个频段集合中的频段可以是相同，也可以不同，本申请对此不做限定。
应理解，第一信息还可以包括第二信元，该第二信元指示第一频段集合与第二频段集合之间的关系。
应理解，第一频段集合和第二频段集合是指支持上行射频链切换的频段集合，终端设 备在一个频段集合中的频段上可以进行上行射频链切换。
示例性地，终端设备可以通过上报频段集合中每个频段中载波支持的最大射频链数量来表明终端设备支持的是哪种切换规则或者切换模式。
例如，切换规则可以是表2、表3或表4对应的切换规则。
例如，如果终端设备上报在一个载波集合中的两个载波上支持的最大射频链数量均是2，且支持并发模式(dual UL)，那么则表明终端设备支持与表4对应的切换规则。
例如，如果终端设备上报在一个载波集合中的一个载波上支持的最大射频链数量是2，在这个载波集合中的另外一个载波上支持的最大射频链数量是1，且支持并发模式(dual UL)，那么则表明终端设备支持表3对应的切换规则。
一种可能的情况是，探测参考信号(sounding reference signal，SRS)资源的最大port数等于基站配置的所有周期SRS、半静态SRS和非周期SRS资源中的最大port数。
一种可能的情况是，SRS资源的最大port数等于基站配置的所有周期SRS、激活的半静态SRS和非周期SRS资源中的最大port数。
一种可能的情况是，终端设备在一个载波支持的最大射频链数量等于或者替换为终端设备上报的这个载波所属频段的SRS资源的最大port数，和/或这个载波上的上行传输支持的最大多输入多输出(multiple input-multiple output，MIMO)的层数和/或这个载波上的非码本传输场景下一个SRS资源集合中的最大SRS资源数量中的一个值或者多个中的最大值。
一种可能的情况是，终端设备在一个载波支持的最大射频链数量等于或者替换为基站给终端设备配置的在这个载波上的SRS资源的最大port数。
一种可能的情况是，一个载波支持的最大射频链数量等价于一个载波的最大射频链数量。
表4示出了一种支持并发模式(dual UL)射频链和上行传输端口的映射关系。与表3的区别在于表4的载波X上的最大射频链数量可以为2。
表4
Figure PCTCN2022085579-appb-000004
例如，上报的频段集合中的两个载波支持的最大射频链数量分别为1T和2T时，网络设备可以认为终端设备支持R16的动态Tx切换，如果上报的频段集合中的两个载波支持的最大射频链数量分别为2T和2T时，网络设备可以认为终端设备支持R17的动态Tx切换。
如果两个频段集合之间是切换的关系，那么网络设备可以认为终端设备在两个频段集合间总共2Tx，或者在两个频段集合的所有频段上总共有2个Tx，那么终端设备在两个频 段集合中的一个频段集合中的至少一个频段上进行传输的同时，不能在两个频段集合中的另一个频段集合中的至少一个频段上进行传输。
如果两个频段集合之间是并发的关系，那么网络设备可以认为终端设备在每个频段集合内都有2Tx，或者在每个频段集合的所有频段上总共有2个Tx，那么终端设备在两个频段集合中的一个频段集合中的至少一个频段上进行传输的同时，也能够在两个频段集合中的另一个频段集合中的至少一个频段上进行传输，即表示这两个频段集合能够独立调度。
应理解，前述步骤S210中，第一关系中的切换是指，终端设备在第一频段集合中的至少一个载波进行上行传输的同时，不能在第二频段集合中的至少一个载波上进行上行传输。
示例性地，终端设备即将在第一频段集合中的至少一个载波上进行上行传输，终端设备之前的一次上行传输是在第二频段集合中的至少一个载波上的上行传输，那么终端设备在第一时间段内不能在两个频段集合中的任何一个载波上进行上行传输。终端设备在第一时间段内需要进行射频链切换。
可选的，如果第二传输是第一传输之前的一次上行传输，那么意味着第一传输和第二传输是时域上相邻的两次传输，且第二传输在第一传输之前。
可选的，第一时间段是终端设备上报的，其指示在这两个频段集合间进行Tx切换的Tx切换时长。
可选的，第一时间段等于两个频段集合中的一个频段集合中的载波上进行Tx切换的Tx切换时长。
可选的，第一时间段等于两个频段集合中的一个频段集合中的载波上进行Tx切换的Tx切换时长和两个频段集合中的另一个频段集合中的载波上进行Tx切换的Tx切换时长中的较大值。
应理解，前述步骤S210中，第一关系中的并发是指，终端设备在第一频段集合中的至少一个载波进行上行传输的同时，可以在第二频段集合中的至少一个载波上进行上行传输。
表5示出了频段集合中每个频段中的载波支持的最大射频链数量。
表5
频段 A B C D
最大射频链数量 1 1 2 2
例如，终端设备上报了两个频段集合，分别是{A，C}，{B，D},且每个频段中载波支持的最大射频链数量如表5所示，那么如果终端设备还上报了第二信元，那么网络设备就可以给终端设备配置两个载波集合，两个载波集合之间的关系可以按照第二信元的指示进行配置。
应理解，通过在第一信息中携带第二信元，本申请能够使能网络设备在给终端设备配置多个载波集合时能够正常调度终端设备。
可选地，第一信息中还可以包括第三信元，该第三信元用于指示终端设备在第一频段组合所支持的射频链数量。
可选的，本申请中，一个频段组合支持的射频链数量、一个频段组合的射频链数量和一个频段组合支持的最大射频链数量三者之间可以互相替换。
可选的，本申请中，一个频段集合支持的射频链数量、一个频段集合的射频链数量和一个频段集合支持的最大射频链数量三者之间可以互相替换。
示例性地，当终端设备上报的两个频段集合中所有的频段，即频段A、B、C和D均属于第一频段组合时，第三信元指示第一频段组合内所有频段集合支持的总的Tx数量，或者指示所有频段集合中的所有载波上支持的总的Tx数量。
例如，表3中载波X支持的最大射频链数量是1，载波Y支持的最大射频链数量是2，载波X所在频段和载波Y所在频段组成的频段集合(定义为第五频段集合)的支持的最大射频链数量是2，如果一个频段组合只包含第五频段集合，那么这个频段组合所支持的射频链数量是2。
例如，表4中载波X支持的最大射频链数量是2，载波Y支持的最大射频链数量是2，载波X所在频段和载波Y所在频段组成的频段集合(定义为第六频段集合)的支持的最大射频链数量是2，如果一个频段组合只包含第六频段集合，那么这个频段组合所支持的射频链数量是2。
可选的，一个载波集合支持的射频链数量可以为这个载波集合中所有载波支持的最大射频链数量中的最大值。例如，表3。
例如，一个频段组合包含第五频段集合和第六频段集合，且这两个频段集合之间的第一关系是切换，那么这个频段组合支持的射频链数量可以是2。
例如，一个频段组合包含第五频段集合和第六频段集合，且这两个频段集合之间的第一关系是并发，那么这个频段组合支持的射频链数量可以是4。
可选的，如果一个频段组合中的每个频段集合支持的射频链数量是相等的，那么可以利用这个频段组合中的频段集合之间的第一关系，推导出每个频段集合支持的射频链数量。可以减少终端上报量。
例如，如果一个频段组合中有两个频段集合，且这两个频段集合之间的第一关系是切换，且这个频段组合支持的射频链数量是2，那么每个频段集合支持的射频链数量均是2。
例如，如果一个频段组合中有两个频段集合，且这两个频段集合之间的第一关系是并发，且这个频段组合支持的射频链数量是4，那么每个频段集合支持的射频链数量均是2。
可选的，如果一个频段组合没有对应的第三信元，那么该频段组合支持的射频链数量可以默认是2。
可选的，一个频段组合所支持的射频链数量可以替换为一个频段组合中可进行Tx切换的射频链数量，也可以替换为一个频段组合中的至少一个频段集合间可进行Tx切换的射频链数量。
例如，如果一个频段组合包含两个第六频段集合(两个第六频段集合上的频段可能不同)，且这两个第六频段集合之间的第一关系是切换，那么这个频段组合中可以进行Tx切换的射频链数量是2。
应理解，当第一信息中还包括第三信元时，则当不同的频段集合中支持的射频链数量包括除2以外数值时，本申请能够使能网络设备更好地调度终端设备。
通过上述技术方案，本申请能够使能网络设备获知终端设备在至少一个载波集合间进行上行Tx切换时可切换的射频链数量，便于网络设备在至少一个载波集合上更灵活地调度终端设备。
可选地，第一信息中还可以包括第四信元，该第四信元用于指示第一频段集合支持的射频链数量，或者说频段集合中的所有载波上支持的总Tx。
示例性地，当频段集合{A，C}支持4个Tx，且频段集合{B，D}支持2个Tx时，并且终端设备在上述两个频段集合间切换时，则具备较多Tx的频段集合{A，C}中有部分Tx只能在这两个频段集合间切换，剩余的Tx不能被频段集合{B，D}共享。
应理解，当第一频段组合中不同的频段集合包括不同数量的Tx数量时，通过在第一信息中携带第四信元，本申请能够使能网络设备在该场景中更好地调度终端设备。
可选的，如果一个频段集合没有对应的第四信元，那么这个频段集合支持的射频数量默认为2。
通过上述技术方案，本申请能够实现在终端设备上报的至少一个频段集合支持的射频链数量不同时，使得网络设备能够获知各个频点集合支持的射频链数量，便于网络设备在至少一个载波集合上更灵活地调度终端设备。
可选的，本申请中，一个载波支持的射频链数量和一个载波的最大射频链数量可以互相替换。
可选的，可以利用一个频段组合中的每个频段集合支持的射频链数量，推导出这个频段组合支持的射频链数量。可以减少终端上报量。
例如，如果一个频段组合中有两个频段集合，且这两个频段集合之间的第一关系是切换，且这两个频段集合支持的射频链数量均是2，那么每个频段组合支持的射频链数量是2。例如，一个频段组合中包含的频段集合之间的关系均为切换，那么这个频段组合支持的射频链数量可以是所包含的所有频段集合中支持的射频链数量的最大值。
例如，如果一个频段组合中有两个频段集合，且这两个频段集合之间的第一关系是并发，且这两个频段集合支持的射频链数量均是2，那么每个频段组合支持的射频链数量是4，即是这两个频段集合支持的射频链数量的和。
例如，如果一个频段组合中有三个频段集合，且这三个频段集合之间的第一关系均是切换，且这三个频段集合支持的射频链数量均是2，那么每个频段组合支持的射频链数量是2。
例如，如果一个频段组合中有两个频段集合，且这两个频段集合之间的第一关系是并发，且一个频段集合支持的射频链数量是2，另一个频段集合支持的射频链数量是4，那么每个频段组合支持的射频链数量是6。
可选地，该第三频段集合包括第五信元，该第五信元用于指示第三频段集合内的第二关系，第二关系包括：切换和/或并发。
当终端设备在每个频段集合中均增加第五信元时，该第五信元用于指示该频段集合内频段之间的第二关系，即第二关系包括：切换和/或并发。
示例性地，当终端设备没有上报第三频段集合的第五信元时，则第三频段集合内频段之间的关系服从第一信息中第六信元的指示，该第六信元指示至少一个频段组合中所有频段集合内频段之间的第三关系，该至少一个频段集合中第四频段集合内频段之间的关系服从第三关系，即第三关系包括：切换和/或并发。
通过上述技术方案，本申请能够实现便于终端设备统一上报部分或全部频段集合中的频段之间的关系，减少上报量。
需要说明的是，如果一个频段集合上报了该频段集合对应的第五信元，那么频段集合内频段之间的关系服从第五信元的指示，
如果一个频段集合没有该频段集合对应的第五信元，那么频段集合内频段之间的关系服从第六信元的指示。
可选的，如果UE上报的一个频段集合中的一个频段支持多个载波，且UE支持在前述多个载波上进行射频链切换，且UE上报了该频段集合对应的第五信元，那么前述多个载波之间的关系服从该频段集合对应的第五信元的指示。
可选的，如果UE上报的一个频段集合中的一个频段支持多个载波，且UE支持在前述多个载波上进行射频链切换，但UE没有上报该频段集合对应的第五信元，那么前述多个载波之间的关系服从第六信元的指示。
可选的，如果UE上报的一个频段集合中的一个频段支持多个载波，且UE支持在前述多个载波上进行射频链切换，那么前述多个载波之间的关系服从该频段集合对应的第八信元的指示。第八信元用于指示一个频段内多个载波之间的第四关系：切换和/或并发和/或共享。
如果至少两个载波之间的关系是共享，那么可以理解为，如果至少一个射频链在至少两个载波中的一个载波上，那么前述至少一个射频链在至少两个载波上是同时可用的。
可选的，如果至少两个载波(或频段)之间的关系是并发，那么可以理解为，UE能被调度或配置上行传输同时在至少两个载波(或频段)上。
可选的，如果至少两个载波(或频段)之间的关系是切换，那么可以理解为，UE不能被调度或者配置上行传输同时在至少两个载波(或频段)上。
通过上述技术方案，本申请能够实现便于终端设备更灵活地上报每个频段集合中的频段之间的关系。
可选地，终端设备上报的至少两个频段集合可以属于至少两个频段集合组，示例性地，当终端设备上报频段集合{A，C}、{B，D}、{A，D}和{C，D}时，则频段集合{A，C}和{B，D}可以属于第一频段集合组，频段集合{A，D}和{C，D}可以属于第二频段集合组。其中，每个频段集合组中的至少两个频段集合之间可以切换和并发，但是不同集合组之间的频段集合不可以切换。
示例性地，当终端设备上报第二频段组合，且该第二频段组合包括A、B、C、D、E、F、G和H共8个频段时，且分为{A，B}，{C，D}，{E，F}，{G，H}，则第一频段集合组包括频段集合{A，B}和{C，D}，第二频段集合组包括频段集合{E，F}和{G，H}，且互相之间并不重叠。其中，每个频段集合组中的至少两个频段集合之间可以切换和并发，但是不同集合组之间的频段集合不可以切换。
例如，第一频段集合组中的频段集合中的所有频段都是低频频段，第二频段集合组中的频段集合中的所有频段都是高频频段，则第一频段集合组中的至少两个频段集合之间可以切换和/或并发，第二频段集合组中的至少两个频段集合之间可以切换和/或并发，第一频段集合组和第二频段集合组中的频段集合之间不可以切换。
通过对频段集合进行分组，不同集合组之间不能切换，本申请使得网络设备获知终端设备在至少一个载波集合间进行上行Tx切换的支持情况。
进一步可选地，第一信息还可以包括第七信元，该第七信元指示至少两个频段集合组 中第三频段集合组支持的射频链数量，或者，指示第三频段集合组中所有载波上支持的总的Tx数量，其中第三频段集合组是至少两个频段集合组中的任意一个频段集合组。
可选的，频段集合组与频段集合的关系可以参考前面的频段组合与频段集合的关系，这里不再赘述。

可选的，一个频段集合组所支持的射频链数量可以替换为一个频段集合组中可进行Tx切换的射频链数量，也可以替换为一个频段集合组中的至少一个频段集合间可进行Tx切换的射频链数量。
通过将频段集合进行分类，本申请能够使得终端设备在同时支持高低频的情况下，在高频和低频内分别进行切换。
应理解，在前述步骤S240中，网络设备可以为终端设备配置M个载波集合，并且该M个载波集合中的第二载波集合中所包括的至少一个载波可以属于同一个频段，也可以属于不同的频段，并且该载波集合内的载波可以同时发送，也可以时分发送；该载波集合间的载波也可以同时发送(并发模式)或者时分发送(切换模式)。
示例性地，如果网络设备为终端设备配置了三个载波集合，分别是载波集合一{CC1，CC2}、载波集合二{CC3，CC4}、载波集合三{CC5}，则载波集合一中的两个载波可以属于同一个频段，载波集合二中的两个载波可以属于两个不同的频段。并且，载波集合一的两个载波可以同时发送(并发关系)，载波集合二的两个载波可以同时发送(并发关系)，载波集合一和载波集合二可以是同时发送(并发关系)，载波集合三和载波集合一可以是时分发送(切换关系)，载波集合三和载波集合二也可以是时分发送(切换关系)。
可选的，网络设备为终端设备配置这三个载波集合之前，终端设备给网络设备上报了至少三个频段集合，频段集合一中至少包括频段1，频段集合二中至少包括频段3和频段4，频段集合三中至少包括频段5，频段集合一内频段之间或一个频段内多个载波之间的关系至少包括并发关系，频段集合二内频段之间的关系至少包括并发关系，频段集合一与频段集合二之间的第一关系为并发，频段集合一与频段集合三之间的第一关系为切换，频段集合二与频段集合三之间的第一关系为切换，CC1和CC2属于频段1，CC3属于频段3，CC4属于频段4，CC5属于频段5。
例如，如果频段集合1和频段集合2之间的第一关系为切换，那么属于频段集合1中频段的载波与属于频段集合2中频段的载波之间的关系为切换。
例如，如果频段集合1和频段集合2之间的第一关系为并发，那么属于频段集合1中频段的载波与属于频段集合2中频段的载波之间的关系为并发。
例如，频段集合内频段之间的关系为切换，那么属于该频段集合中不同频段的载波之间的关系为切换。
例如，频段集合内频段之间的关系为并发，那么属于该频段集合中不同频段的载波之间的关系为并发。
应理解，当终端设备向网络设备上报了频段集合之间的第一关系时，则网络设备为终 端设备配置的载波集合之间的关系也服从该第一关系，或者说是网络设备为终端设备配置的载波集合之间的关系与该第一关系保持一致。其中，载波集合中的载波属于频段集合中的频段。
可选的，在本申请中，载波集合可以替换为载波组，频段集合也可以替换为频段组，本申请对此不做具体限定。
通过上述技术方案，本申请能够使得网络设备能够获知终端设备在至少一个载波集合组进行上行Tx切换时，可切换的射频链数量，便于网络设备在至少一个载波集合组上更好地调度终端设备。
需要说明的是，在上述技术方案中，每个频段集合中包括至少两个频段，且每个频段集合可以仅包括同一个频段，示例性地，如频段集合{A，A}。
图3示出了本申请提供的另一种信息发送和接收的方法。该方法的执行主体是网络设备和终端设备，具体方法如图3所示：
S310，终端设备确定第一信息，该第一信息包括第一信元，第一信元指示至少两个频段集合，该至少两个频段集合中第一频段集合包括至少一个频段，该至少两个频段集合中任意两个频段集合之间包含至少一个相同的频段。
S320，终端设备向网络设备发送第一信息。
S330，网络设备接收来自终端设备的第一信息。
S340，网络设备配置第一载波集合，第一载波集合中的载波所属的频段组成的频段集合不属于所述至少两个频段集合。
可选的，集合A属于集合B是指，集合A中的所有元素在集合B中都存在，如果集合A中有元素不在集合B中，那么集合A不属于集合B。
应理解，在前述步骤S310中，当终端设备上报了至少两个频段集合，且该至少两个频段集合中任意两个频段集合之间包含至少一个相同的频段时，那么网络设备会认为终端设备支持在这多个频段组成的新频段集合上进行动态Tx切换；又或者，终端设备上报了至少两个频段集合，且该至少两个频段集合中任意两个频段集合之间包含至少一个相同的频段时，且上报的相同频段支持的射频链数量均不为零，那么网络设备会认为终端设备支持在这多个频段组成的新频段集合上进行动态Tx切换。其中，这里的新频段集合中包含至少一个相同频段。
具体地，如果终端设备上报的频段集合为{A，C}和{C，D}，且该频段集合{A，C}和频段集合{C，D}之间存在一个相同的频段{C}，那么网络设备可以认为终端设备支持在频段集合{A，C，D}上进行动态Tx切换。且当A或D上有Tx时，都可以向C进行Tx切换；C上有Tx时，都可以向A或D上进行Tx切换；A上有Tx时，不能向D切换Tx；D上有Tx时，不能向A切换Tx。
如此，网络设备能够为终端设备配置新的载波集合，且该新载波集合中的载波所属的频段组成的频段集合为或属于频段集合{A，C，D}，且该新载波集合中的载波所属的频段组成的频段集合不属于终端设备上报的频段集合。
应理解，由于频段集合{A，C}和频段集合{C，D}之间只是部分频段相同，所以不相同的频段在Tx切换时不能任意切换，只能在终端设备上报的频段集合中的另外一个频段上有Tx时才能进行Tx切换。
应理解，在本申请中，在一个频段的集合上支持动态Tx切换，等价于在一个频段的集合中的载波上支持动态Tx切换。
又例如，如果终端设备上报的频段集合为{A，C}和{C，D}，且终端设备上报了如表6所示的每个频段集合中每个载波支持的最大射频链数量，那么网络设备可以认为终端设备支持在频段集合{A，C，D}上进行动态Tx切换。且当A或D上有Tx时，都可以向C进行Tx切换；C上有Tx时，都可以向A或D上进行Tx切换；A上有Tx时，不能向D切换Tx；D上有Tx时，不能向A切换Tx。
如此，网络设备能够为终端设备配置新的载波集合，且该新载波集合中的载波所属的频段组成的频段集合为或属于频段集合{A，C，D}，且该新载波集合中的载波所属的频段组成的频段集合不属于终端设备上报的频段集合。
表6
频段 A C D
最大射频链数量 1 2 2
一种可能的实现方式是，在终端设备上报的至少两个频段集合中，如果存在至少三个频段集合中的至少三个频段在该至少三个频段集合中出现至少两次，或者，至少三个频段集合中的所有频段在该至少三个频段集合中出现至少两次，那么网络设备会认为终端设备支持在一个新的频段集合中进行动态的Tx切换。其中，该新频段集合是由出现至少两次的这至少三个频段组成。
示例性地，如果终端设备上报的频段集合为{A，C}，{A，D}，{B，C}，{C，D}，且频段A、C和D分别在频段集合中{A，C}，{A，D}和{C，D}均出现了两次，那么网络设备可以认为终端设备支持在频段集合{A，C，D}上进行动态Tx切换。如此，网络设备能够为终端设备配置新的载波集合，该新载波集合中的载波所属的频段组成的频段集合为或属于频段集合{A，C，D}，且该新载波集合中的载波所属的频段组成的频段集合不属于终端设备上报的频段集合。
例如，如果终端设备上报的频段集合为{A，C}，{A，D}，{B，C}，{C，D}，且终端设备上报了如表7所示的每个频段集合中每个载波支持的最大射频链数量，那么网络设备会认为终端设备支持在频段集合{A，C，D}上进行动态Tx切换。
如此，网络设备能够为终端设备配置新的载波集合，且该新载波集合中的载波所属的频段组成的频段集合为或属于频段集合{A，C，D}，且该新载波集合中的载波所属的频段组成的频段集合不属于终端设备上报的频段集合。
表7
频段 A B C D
最大射频链数量 1 0 2 2
又例如，如果终端设备上报的频段集合为{A，C}，{A，D}，{B，C}，{C，D}，{A，B}，{B，D},且频段A、B、C和D分别在频段集合中{A，C}，{A，D}，{B，C}，{C，D}，{A，B}，{B，D}分别出现了三次，那么网络设备可以认为终端设备支持在频段集合{A，B，C，D}上进行动态Tx切换。如此，网络设备能够为终端设备配置新的载波集合，且该新载波集合中的载波所属的频段组成的频段集合为或属于频段集合{A，B，C，D}， 且该新载波集合中的载波所属的频段组成的频段集合不属于终端设备上报的频段集合。
又例如，如果终端设备上报的频段集合为{A，C}，{A，D}，{B，C}，{C，D}，{A，B}，{B，D}，且终端设备上报了如表8所示的每个频段集合中每个载波支持的最大射频链数量，那么网络设备可以认为终端设备支持在频段集合{A，B，C，D}上进行动态Tx切换。
如此，网络设备能够为终端设备配置新的载波集合，且该新载波集合中的载波所属的频段组成的频段集合为或属于频段集合{A，B，C，D}，且该新载波集合中的载波所属的频段组成的频段集合不属于终端设备上报的频段集合。
表8
频段 A B C D
最大射频链数量 1 1 2 2
通过终端设备向网络设备上报多个频段集合和/或重叠频段载波上行支持的最大射频链数量，本申请能够使能终端设备上报动态Tx切换集合中频段数大于2的情况。通过上述技术方案，当终端设备上报的至少两个频段集合之间任意两个频段集合中包含相同的频段时，网络设备会认为终端设备支持在一个新的频段集合中支持动态的Tx切换，从而能够更好地对终端设备进行调度，并且网络设备能够为终端设备配置包含多个频段的载波集合，且该载波集合中的载波所属的频段组成的频段集合不属于终端设备上报的原有的频段集合。
