首先对本申请实施例中涉及到的相关概念进行介绍：
R16引入上行发射通道切换(UL Tx switching)的机制，即一个终端最多同时在2个发射通道Tx发送，一个载波支持一个上行发射通道(如载波1)，另一个载波支持两个发射通道(如载波2)，载波1和载波2在不同的频带(band)，通过切换Tx从而支持两种模式的切换，模式一：在载波2上进行上行双流传输，模式二：在载波1和/或载波2进行单流传输。
根据是否支持载波1和载波2同时进行上行传输分为option1(网络配置高层参数uplinkTxSwitchingOption-r16为switchedUL，表示载波1和载波2不可以同时进行上行传输)和option2(网络配置高层参数uplinkTxSwitchingOption-r16为dualUL，表示载波1和载波2可以同时进行上行传输)。
R16支持的UL Tx switching情况如下：
首先，需要说明的是：1T+1T表示载波1有1Tx，载波2有1Tx；1P+0P表示载波1有1个天线端口发送，载波2有0个天线端口发送(也即没有数据发送)；可以认为1Tx最多支持1个天线端口发送；图2a-图2d、图3a-图3b和图4中箭头表示Tx切换前和Tx切换后。
1、对LTE和NR的双连接(E-UTRA-NR Dual Connectivity，EN-DC)，支持option1和option2，协议规定E-UTRA上行载波为载波1，NR载波为载波2，option1如图2a和图2b所示，option2如图2c和图2d所示。
2、支持带间载波聚合(inter-Carrier Aggregation，inter-CA)，支持option1和option2，通过网络配置载波聚合的两个载波为载波1或载波2，option1如图2a和图2b所示，option2如图3a和图3b所示。
3、支持辅助上行载波(Supplementary uplink carrier，SUL)，只支持OPTION 1，通过网络配置SUL或UL为载波1或载波2，如图4所示。
终端上报能力：
通过参数uplinkTxSwitching-OptionSupport上报支持option1、option2或者两者都支持。通过参数uplinkTxSwitchingPeriod上报UL Tx switching需要的时间。通过参数uplinkTxSwitching-DL-Interruption上报支持下行中断的频带band。
网络高层参数uplinkTxSwitchingOption用于配置终端支持option 1或option2。uplinkTxSwitching用于配置该服务小区(serving cell)是否用于UL Tx switching。uplinkTxSwitchingPeriodLocation用于配置切换时间(如切换周期、起始位置、结束位 置)关联的小区，用于确定切换时间的位置。
uplinkTxSwitchingCarrier用于配置载波为carrier1或carrier 2，用于确定支持的端口port数目和切换模式。
进一步，R17阶段扩展了inter-CA和SUL的切换情况。首先支持2Tx-2Tx的切换，即对两个载波都支持两个Tx的情况之间的切换。进一步，还支持在band A上有一个载波和band B上有两个连续载波(这两个载波可以用同一个Tx发送)之间的Tx切换。并且引入了两个新的无线资源控制(Radio Resource Control，RRC)参数，一个参数用于指示1Tx-2Tx的切换模式还是2Tx-2Tx的切换模式，从而确定是采用1Tx-2Tx或2Tx-2Tx的切换参数；当UL Tx切换后的Tx状态不唯一，一个参数用于指示Tx状态是1Tx+1Tx，或者Tx状态是0Tx+2Tx。例如，当配置了uplinkTxSwitchingPeriod2T2T-r17，则终端支持2Tx-2Tx切换，且配置的切换周期通过uplinkTxSwitchingPeriod2T2T-r17确定，如果没有配置该参数(即该参数的值为空)，则配置的切换周期通过uplinkTxSwitchingPeriod-r16确定。值得注意的是，1Tx-2Tx和2Tx-2Tx支持的切换模式是有部分交叠的，即有的切换模式既可以属于1Tx-2Tx，也可以属于2Tx-2Tx，不同在于不同模式的切换参数会不同。
目前终端最多可以同时在2个发射通道进行上行发送，而且2个发射通道只支持在2个上行UL频带间进行切换/传输。未来终端可能支持大于2个上行(Uplink)和/或侧链路(Sidelink)频带。因此，对于本领域技术人员来说，亟需解决如何实现一种支持在大于2个频带的情况下终端进行传输或发射通道切换的方案的问题。
下面结合附图，通过一些实施例及其应用场景对本申请实施例提供的通信方法进行详细地说明。
图5是本申请实施例提供的通信方法的流程示意图之一。如图5所示，本实施例提供的方法，包括：
步骤101、终端基于目标信息在N个物理单元中的至少一个物理单元进行传输；
其中，传输是基于M个发射通道中的至少一个发射通道的传输，或，传输是在发射通道切换后的物理单元上基于M个发射通道中的至少一个发射通道的传输；N为大于2的整数；M为小于或者等于N的正整数；目标信息包括以下至少一项：

具体地，终端的配置资源包括N个物理单元，物理单元例如为载波、频带、BWP或资源池等，终端在N(N＞2)个物理单元中的至少一个物理单元进行传输，该传输指的是基于M个发射通道中的至少一个发射通道的传输，或，传输是指在发射通道切换后的物理单元上基于M个发射通道中的至少一个发射通道的传输。
终端的传输或切换情况与目标信息有关，其中目标信息中某个发射通道支持的物理单元，指的是该物理单元的数据可以通过该发射通道发射，例如，Tx1支持{频带1、频带2和频带3}表示频带1、频带2和频带3的数据可以通过发射通道Tx1进行发送，Tx2支持{频带1、频带2}表示频带1和频带2的数据可以通过发射通道Tx2进行发送；某个物理单元支持的发射通道指的是物理单元发送数据时可使用的发射通道，例如，物理单元1支持Tx1表示物理单元1可使用发射通道Tx1发送数据，物理单元2支持Tx1和Tx2表示物理单元2可以使用发射通道Tx1和Tx2发送数据。
M个发射通道的至少两个发射通道之间的关联关系，表示M个发射通道中至少一个发发射通道与其他至少一个发射通道之间的关联性，例如Tx1传输或切换的过程中，Tx2不能传输、被调度或切换，即不允许Tx2传输、被调度或切换，或，Tx2可以传输、被调度或切换。
可选地，终端在物理单元支持传输的最大端口数目(即最大天线端口数目)等于或小于该物理单元支持的Tx数目。
需要说明的是，N个物理单元例如可以通过不同的类型的物理单元进行配置，例如终端配置了3个载波，这3个载波是在2个band上的，因此N个物理单元可以为2个band。
本实施例的方法，终端可以基于目标信息在大于2个物理单元中的至少一个物理单元进行传输，可以是基于M个发射通道中至少一个发射通道的传输，或，在发射通道切换后的物理单元上基于M个发射通道中的至少一个发射通道的传输；目标信息包括以下至少一项：M个发射通道中每个发射通道支持的物理单元；N个物理单元中每个物理单元支持的发射通道数目；M个发射通道的至少两个发射通道之间的关联关系；N个物理单元中每个物理单元支持的端口数目，从而在基于目标信息的基础上实现了支持大于2个物理单元的情况下终端进行传输或发射通道切换的方案。

可选地，在每个发射通道分别支持的物理单元中存在至少一个相同的物理单元的情况下，部分Tx支持的物理单元集合包含配置的N个物理单元，部分Tx支持的物理单元包含配置的N个物理单元中部分物理单元。

可选地，在每个发射通道分别支持的物理单元中的全部物理单元均相同的情况下，每个Tx支持的物理单元集合包含配置的N个物理单元。
或，M个Tx支持的物理单元集合完全不同。

每个物理单元支持的最大发射通道数目均为M；
N个物理单元中至少一个物理单元支持的最大发射通道数目小于M；
N个物理单元中至少一个物理单元支持的最大发射通道数目等于M。
具体地，每个物理单元都支持最大M个Tx；或，部分物理单元支持最大M个Tx，或部分物理单元支持小于M个Tx，或全部物理单元均支持小于M个Tx。
可选地，M个发射通道的至少两个发射通道之间的关联关系，满足以下至少一种情况：
M个发射通道中至少一个发射通道在传输或切换过程中，M个发射通道中其他的至少一个发射通道不允许传输或切换；
M个发射通道中至少一个发射通道在传输或切换过程中，M个发射通道中其他的至少一个发射通道允许传输或切换。
例如，部分Tx进行传输或切换过程中，其他Tx不能传输、被调度或切换；
部分Tx进行传输或切换过程中，其他Tx可以传输、被调度或切换。
可选地，关联关系为基于以下至少一种粒度确定的：物理单元、终端、频带组合(band combination)或频带列表。
例如，部分物理单元发生Tx切换时，或部分物理单元之间发生Tx切换时，或者从第一传输情况切换到第二传输情况时，其他物理单元或没有参与Tx切换的物理单元可以或不能正常进行传输、被调度或切换。
其中，部分物理单元指特定物理单元或任意物理单元；部分Tx指特定Tx或任意Tx。
例如，终端的某个物理单元发生切换时，或部分物理单元之间发生Tx切换时等情况，终端的其他物理单元或没有参与Tx切换的物理单元可以或不能正常进行传输、被调度或切换。
例如，某个频带组合中的某个物理单元发生切换时，该频带组合中的其他物理单元或没有参与Tx切换的物理单元可以或不能正常进行传输、被调度或切换。
上述实施方式中，根据目标信息满足的至少一种条件进行传输或Tx切换，即终端可以在哪些情况下进行传输或Tx切换，终端实现复杂度较低。

具体地，每个Tx支持的物理单元集合相同，且物理单元集合为配置传输的N个物理单元，或每个物理单元都支持最大M个Tx，则每个物理单元可以包括0～M个Tx且N个物理单元的Tx总数不能超过M。
例如，M＝2，所有物理单元共支持2个Tx。
可选地，在每个发射通道分别支持的物理单元中存在至少一个相同的物理单元的情况下，N个物理单元中第一目标物理单元支持的发射通道数目的取值范围为0-M，N个物理单元中第二目标物理单元支持的发射通道数目的取值范围为0-1，且N个物理单元的发射通道总数不超过M；第一目标物理单元为至少两个发射通道支持的物理单元；第二目标物理单元为只有一个发射通道支持的物理单元。
具体地，各个Tx分别支持的物理单元集合中存在至少一个相同的物理单元，则至少一个相同的物理单元(即多个物理单元集合的交集中的物理单元，即第一目标物理单元)可以包括0～M个Tx，即支持的最大发射通道数目为M，至少两个发射通道均支持该物理单元，其他物理单元可以包括0～1个Tx，即持的最大发射通道数目为1，只有一个发射通道支持该物理单元，且N个物理单元的Tx总数不能超过M。
例如，对于3个band，Tx1支持{band A，band B，band C}，Tx2支持{band A，band B}，那么终端支持band A和band B上发送最多2个Tx(例如最多支持2个port)，band C最多只能发送一个Tx(最多支持1个port)的传输。
可选地，在每个发射通道分别支持的物理单元均不相同的情况下，每个物理单元支持的最大发射通道数目为1，且N个物理单元的发射通道总数不超过M。
具体地，各个Tx支持的物理单元集合完全不同，则每个物理单元最多包括1个Tx，且N个物理单元的Tx总数不能超过M。
例如，对于4个band，Tx1支持band A和band B，Tx2支持band C和band D，那么终端只能支持在band A或band B使用Tx1传输，和/或支持在band C或band D使用Tx2传输。
可选地，步骤101满足以下条件：
在至少一个发射通道的传输或切换过程中，终端不进行M个发射通道中其他发射通道的传输或切换；或，
在至少一个发射通道传输或切换过程中，终端可进行M个发射通道中其他发射通道的传输或切换。
具体地，部分Tx传输或切换过程中，终端不能在其他Tx传输、被调度或切换。
部分Tx传输或切换过程中，终端可以在其他Tx传输、被调度或切换。
可选地，终端不进行M个发射通道中其他发射通道的传输或切换，包括：终端不在预设物理单元上进行M个发射通道中其他发射通道的传输或切换；
终端可进行所述M个发射通道中其他发射通道的传输或切换，包括：终端可在预设物理单元上进行M个发射通道中其他发射通道的传输或切换。
示例一：
当M＝2，N＝3，终端配置了3个上行载波(carrier 1，carrier 2，carrier 3)，分别在3个band(band A，band B，band C)上。
1、假设规定终端配置的可以做Tx switching的band满足如下条件：每个band都支持2个Tx，或每个Tx都支持3个band。终端可以在如表1所示的任一传输情况进行传输：
表1
2、当终端上报band A和band B可以支持2个Tx，band C只能支持1个Tx，则终端可以在如表2所示的任一传输情况进行传输：
表2
3、当网络配置Tx 1支持band A和band B，Tx 2支持band B和band C，则终端可以在如表3所示的任一传输情况进行传输：
表3
上述实施方式中，明确了终端可以在哪些情况下进行传输或Tx切换，Tx切换前后支持哪些传输情况，终端实现复杂度较低。
可选地，该方法还包括：
终端接收网络侧设备的用于发射通道传输和/或切换的指示信息；

至少两个指示信息的参数满足第一条件；所述参数包括以下至少一项：搜索空间、监测时机、格式、大小、资源池或时频资源；
至少两个指示信息调度的物理单元满足第二条件。
例如，两个指示信息的时间间隔满足预设时间间隔，例如小于、大于或等于预设时间间隔；
两个指示信息对应的参数满足预设的第一条件，例如参数的取值相同、取值的差值满足预设差值，例如大于或小于预设差值。
两个指示信息调度的物理单元满足预设的第二条件，例如调度的物理单元相同，或，至少两个指示信息调度的物理单元中不同的物理单元被调度进行传输或切换的开始时间的差值大于、小于或等于预设值。
例如，包括P(P＞＝1)个Tx切换，可以通过P个指示信息触发，或1个指示信息触发，例如1个指示信息可以调度多个物理单元。
可选地，在终端收到第一个所述指示信息的情况下，若在预设时长内收到第二个所述指示信息，则所述终端基于目标信息在所述N个物理单元中的至少一个物理单元进行传输；或，
所述方法还包括：
若在预设时长内没有收到第二个所述指示信息，则所述终端在最多2个物理单元中的至少一个物理单元进行传输。
示例性地，当终端收到第一个DCI，按照2个band的规定(例如R16/R17协议规定的)传输或切换，例如在预设时长内没有收到第二个指示信息，按照2个band的规定传输或切换。当终端收到第二个DCI，按照前述任一方法实施例的方法进行传输或切换，即基于目标信息在N个物理单元上进行M个发射通道中至少一个发射通道的传输或切换。
上述实施方式中，对大于2个band的情况下，通过网络侧设备配置或动态指示终端进行传输或Tx切换的触发条件，终端实现复杂度低，有较好的向后兼容性。
示例二：终端的Tx切换通过两个指示信息(如DCI)触发，例如，对示例一的第1种情况，假设终端当前的传输情况在case 3，当终端收到第一个DCI调度carrier 2的传输，终端执行2T+0T+0T→1T+1T+0T(R16/R17行为)的切换，当终端在协议规定时间内接收到第二个DCI调度carrier 3的传输，终端执行2T+0T+0T→0T+1T+1T(R18行为)的切换。
可选地，M个发射通道中至少一个发射通道切换采用的类型包括第一类型和第二类型；
第一类型为至少一个发射通道在切换前对应的物理单元和切换后对应的物理单元完全不同或部分不同；
第二类型为至少一个发射通道在切换前对应的物理单元和切换后对应的物理单元相同，或，为至少一个发射通道的数目为1。
具体地，第一类型即复杂传输情况变化，指的是切换前对应的物理单元和切换后对应的物理单元完全不同或部分不同。例如，如表4-表6所示的以下case间的切换：
表4
如表4中，Case1切换到Case4，切换前对应的物理单元为band A和band B，切换后对应的物理单元为band C，切换前和切换后对应的物理单元全部不同；表4也可以表示Case4切换到Case1，与Case1切换到Case4类似。
表5
如表5中，Case3切换到Case6，切换前对应的物理单元为band A，切换后对应的物理单元为band C和band B，切换前和切换后对应的物理单元全部不同；表5也可以表示Case6切换到Case3，与Case3切换到Case6类似。
表6
如表6中，Case1切换到Case6，切换前对应的物理单元为band A和band B，切换后对应的物理单元为band C和band B，切换前和切换后对应的物理单元部分不同；表6也可以表示Case6切换到Case1，与Case1切换到Case6类似。
第二类型即简单传输情况变化，指的是切换前对应的物理单元和切换后对应的物理单元完全相同，或，传输或切换的发射通道数目为1。例如，如表7-表14所示的以下case间的切换：
表7
如表7中，Case1切换到Case2，进行切换的发射通道数目为1，切换前和切换后用于传输的发射通道数目为1或2，band A上的发射通道切换至band B上；表7也可以表示Case2切换到Case1，与Case1切换到Case2类似。
表8
如表8中，Case5切换到Case3，进行切换的发射通道数目为1，切换前和切换后用于传输的发射通道数目为1或2band C上的发射通道切换至band A上；表8也可以表示Case3切换到Case5，与Case5切换到Case3类似。
表9
如表9中，Case1切换到Case3，进行切换的发射通道数目为1，切换前和切换后用于传输的发射通道数目为1或2，band B上的发射通道切换至band A上；表9也可以表示Case3切换到Case1，与Case1切换到Case3类似。
表10

如表10中，Case2切换到Case6，进行切换的发射通道数目为1，切换前和切换后用于传输的发射通道数目为1或2，band B上的发射通道切换至band C上；表10也可以表示Case6切换到Case2，与Case2切换到Case6类似。
表11
如表11中，Case4切换到Case6，进行切换的发射通道数目为1，切换前和切换后用于传输的发射通道数目为1或2，band C上的一个发射通道切换至band B上；表11也可以表示Case6切换到Case4，与Case4切换到Case6类似。
表12
如表12中，Case4切换到Case5，进行切换的发射通道数目为1，切换前和切换后用于传输的发射通道数目为1或2，band C上的一个发射通道切换至band A上；表12也可以表示Case5切换到Case4，与Case4切换到Case5类似。
表13
如表13中，Case 2、Case 3和Case 4之间可以互相切换，例如从Case2切换到 Case3，进行切换的发射通道数目为2，切换前和切换后用于传输的发射通道数目为1或2，band B上的发射通道切换至band A上；其他切换情况类似。
表14
如表14中，Case 1、Case 5和Case 6之间可以互相切换，例如Case1切换到Case5，进行切换的发射通道数目为1，切换前和切换后用于传输的发射通道数目为1或2，band B上的发射通道切换至band C上。Case5切换到Case6，进行切换的发射通道数目为1，切换前和切换后用于传输的发射通道数目为1或2，band A上的发射通道切换至band B上。
可选地，步骤101还可以采用如下方式实现：
基于目标信息在N个物理单元上进行M个发射通道中至少一个发射通道的多次第二类型的切换。
具体地，终端的复杂传输情况变化可以为多个简单传输情况变化的组合。终端被触发复杂传输情况变化时，可以按多个简单传输情况变化的步骤进行传输或Tx切换。
例如，如下表15所示的Case1切换到Case4的情况，可以转换为两次切换，即先从Case1切换到Case5，再从Case5切换到Case4，如表16和表17所示：
表15
表16

表17
可选地，以上天线端口和Tx的对应关系作为示例，天线端口可以为以上示例中每一行的子集。
上述实施方式中，简化了协议复杂度，终端只需把复杂的情况拆解为简单情况进行处理即可，终端实现复杂度较低。
