首先对本申请涉及的相关内容进行介绍。
一、上行发射通道切换
R16引入上行发射通道切换(uplink Tx switching，或UL Tx switching)的机制，即 一个UE最多同时在2个Tx发送，一个载波支持一个上行发射通道(载波1)，另一个载波支持两个发射通道(载波2)，载波1和载波2在不同的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(dualUL，网络配置高层参数uplinkTxSwitchingOption-r16为switchedUL，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：
1.对演进型全球地面无线接入(Evolved Universal Terrestrial Radio Access，E-UTRA)到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；
2.支持带外载波聚合(inter-band Carrier Aggregation，inter-band 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；
3.支持辅助上行链路(supplementary uplink，SUL)，只支持OPTION 1，通过网络配置SUL或UL为载波1或载波2。
UE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switching gap。通过参数uplinkTxSwitching-DL-Interruption上报支持下行中断的band。
网络高层参数uplinkTxSwitchingOption用于配置UE支持option1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port数目和切换案例(case)。
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UE支持2Tx-2Tx切换，且配置的切换时间通过uplinkTxSwitchingPeriod2T2T-r17确定，如果没有配置该参数(即该参数的值为空)，则配置的切换时间通过uplinkTxSwitchingPeriod-r16确定。值得注意的是，1Tx-2Tx和2Tx-2Tx两种模式支持的切换case是有部分交叠的，即有的切换case既可以属于1Tx-2Tx，也可以属于2Tx-2Tx，不同在于切换参数根据模式会不同。
当触发了uplink Tx switching，对以下case需要额外的UL Tx switching的时间，包括物理上行共享信道(Physical Uplink Shared Channel，PUSCH)传输、非周期的探测参考信号(Sounding Reference Signal，SRS)传输、物理下行控制信道(Physical Downlink Control Channel，PDCCH)触发的物理随机接入信道(Physical Random Access Channel，PRACH)传输和信道状态信息(Channel State Information，CSI)的传输的处理过程时间。其中PUSCH传输的准备过程时间为Tproc,2＝max((N2+d2,1)(2048+144)·κ2-μ·TC+Tswitch,d2,2)，N2由承载调度下行控制信息(Downlink Control Information，DCI)的PDCCH的μDL和传输的PUSCH的μUL对应的较大的处理时间确定(不同的子载波间隔(sub-carrier space，SCS)对应不同的处理时间)，Tswitch为UE上报的UL Tx switching的时间；值得注意的是，对于inter-band CA的option2，μUL＝min(μUL,carrier1,μUL,carrier2)。
二、在UL Tx switching过程中终端的限制
在UL Tx switching过程中，终端有如下的限制：
终端在切换时间内不期待在进行切换的carrier或band上进行传输。
当一个开始时间为T0的上行传输触发UL Tx switching，那么在T0-T_offset后，终端不期待取消该UL Tx switching，或者T0-T_offset后调度其他的上行传输且触发在T0之前开始的任意其他新的上行切换,T_offset为上行传输的处理过程时间。
终端不期待在子载波间隔SCS为μUL＝max(μUL,carrier1,μUL,carrier2)的一个时隙(slot)内执行超过一次UL Tx switching，其中μUL,carrier1,为切换时间前上行传输的子载波间隔，μUL,carrier2为切换时间后上行传输的子载波间隔。
相关技术只在2个band上进行UL Tx switching，R18引入大于2个band(3个、4个band)的UL Tx switching。当上行传输触发了大于2个band的UL Tx switching，对上行传输额外的UL Tx switching的时间尤其是inter-band CA的option2，如何确定Tproc,2需要确定，并且终端在UL Tx switching过程中的限制会随着band数目的增多有所变化。
图2为相关技术中终端在4个band上进行UL Tx switching的示意图。如图2所示，从(1Tx)CC1+(1Tx)CC2切换到(1Tx)CC3+(1Tx)CC4，两个Tx的切换前后的载波皆不同，1个Tx从CC1切换到CC3，一个Tx从CC2切换到CC4，根据现有技术，UE不能在切换周期(switching period)1和switching period 2传输，因此CC3的传输会受到影响。
图3为相关技术中终端在3个band上进行UL Tx switching的示意图。如图3所示，从(1Tx)CC1+(1Tx)CC2切换到(2Tx)CC3，T_offset，1根据CC1、CC3的SCS得到，T_offset， 2根据CC2、CC3的SCS得到。在switching gap(假设为35us)里执行了两次UL Tx switching，与现有技术的一个slot(假设为15kHz对应的71us)内不能执行超过一次UL Tx switching的规定相悖。
因此，如何实现3个band或4个band的Tx切换并进行正常的上行传输是需要解决的。为了解决上述问题，本申请实施例提供了发射通道切换的处理方法、终端及网络侧设备。
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发射通道切换的处理方法、终端及网络侧设备进行详细地说明。
图4为本申请实施例提供的发射通道切换的处理方法的流程示意图之一。如图4所示，该方法包括：
步骤400、终端基于N个传输中的第一传输，确定所述N个传输对应的第一时域位置；
其中，N为大于等于2的整数，所述N个传输为触发发射通道切换的传输，所述N个传输中的各个传输对应的第一时域位置均相同。
在本申请实施例中，传输可以包括数据信道/控制信道/参考信号/随机接入信道等。
可以理解，终端基于N个传输中的第一传输，确定N个触发发射通道切换的传输对应的第一时域位置，且各个传输对应的第一时域位置均相同，不会在一个传输的Tx切换过程中开始另一个传输，可以保证Tx切换过程中的正常传输，减少终端复杂度，提高吞吐量。
需要说明的是，本申请实施例提供的方法并不限于3个或4个band，也可以应用于更多的band数目，可实现3个或4个或更多band之间的Tx切换过程中的正常传输。
可选地，所述第一时域位置为所述第一传输的开始时刻，或者，所述第一传输所在的时间单元的起始位置。

c)所述N个传输中除了所述第一传输的其他传输的开始或结束位置，和第一传输的开始或结束位置所在时间单元的起始位置的差值在所述第一范围内；
例如，第一传输的时间范围为[T1,T2]，那么其他传输的时间范围为[T1-ΔT1,T2+ΔT2]，其中，ΔT1,ΔT2分别为第一时长,第二时长，ΔT1,ΔT2可以由协议约定或网络配置或终端确定。
d)在第一信息接收时刻之后的第一时间窗口内或在至少包括所述第一信息的第一时间窗口内接收到第二信息，其中，所述第一信息用于调度或配置所述第一传输，所述第二信息用于调度或配置所述N个传输中除了所述第一传输的其他传输中的任意传输。
可以理解的是，当终端接收到第一信息，其中，第一信息用于调度或配置第一传输，例如，DCI，下面以信息为DCI为例进行说明，包括但不限于DCI，还可以包括RRC信令或旁链路控制信息(SideLink control information)SCI等，确定第一时间窗口，即第一时间窗口内的信息调度或配置的传输的第一时域位置T0为同一个。
第一时间窗口在第一信息接收时刻之后，也可以是至少包括第一信息的时间窗口。
可选地，所述第一时间窗口的长度为协议规定或网络配置或终端上报。
例如，协议规定对不同的SCS，第一时间窗口的值不同，所述SCS可以为第一信息所在的载波的SCS，或第一信息调度或配置的传输所在载波的SCS。
又例如，网络配置或者UE上报对不同的第一信息调度的天线端口数目，或第一信息调度的载波数目，或配置的Tx切换模式，第一时间窗口的值不同。
可选地，所述第一时间窗口的起始位置为所述第一信息的接收时刻，即第一信息的开始位置，所述第一时间窗口的结束位置为所述第一传输对应的第一时域位置往前偏移所述第一传输对应的准备过程时长的位置，即T0-T_offset，其中，T0为第一传输对应的第一时域位置，可以是第一传输的开始时刻，或者，所述第一传输所在的时间单元的起始位置，T_offset为第一传输对应的准备过程时长。
可选地，所述第一时间窗口的长度根据以下至少一项确定：
所述第一信息所在的载波的子载波间隔；

例如，第一时间窗口的长度与第一DCI所在的载波的SCS，或者，第一DCI调度的传输(即第一传输)所在载波的SCS有关。
其中，所述第一信息调度的参数包括以下至少一项：第一信息调度的天线端口数目、载波数目、频带数目等。
第一时间窗口的长度和发射通道切换类型也有关,类型可以包括以下:
类型一，类似于R16/17 UL Tx在2频段之间切换，例如1Tx-2Tx在第一频段1Tx和第二频段2Tx之间切换，包括以下情况之间的Tx切换：





类型二，类似于R16/17 UL Tx在2个频段之间切换，例如2Tx-2Tx切换，其中2Tx从第一个频段切换到第二个频段，包括以下情况之间的Tx切换：
类型三，UL Tx在3或4个频段上切换，例如，1个Tx从第一个频段切换到第二个频段，而另一个Tx保持在第三个频段：
类型四，UL Tx在3个或4个频段上切换，例如，1个Tx和另一个TX分别从第一频段和第二频段切换到第三频段，反之亦然：


类型五，特定于4个频段的UL Tx切换，例如，TX切换涉及两个源频段和另外两个目标频段：


配置的发射通道切换的模式包括：switchedUL，dualUL。
可选地，所述第一传输为所述N个传输中开始时刻最早的传输，或者，所述第一传输为第一时间窗口前接收的第一信息调度或配置的传输。
可以理解，所述第一传输为所述N个传输中开始时刻最早的传输，那么第一传输对应的第一时域位置即为N个传输中开始时刻最早的传输的开始时刻，所述N个传输中的各个传输对应的第一时域位置均为所述第一传输的开始时刻。
例如，第一时间窗口包括DCI1，DCI2，DCI1、DCI2调度的传输的开始时刻分别为T1,T2,且T1>T2，则第一时域位置T0＝T2。
或者，N个传输中的各个传输对应的第一时域位置均为第一时间窗口前接收的第一信息调度或配置的传输的开始时刻。
可选地，所述方法还包括：
所述终端基于N个传输中的第一传输，确定所述N个传输对应的准备过程时长；
其中，所述N个传输中除了所述第一传输的其他传输中的任意传输对应的准备过程时长均与所述第一传输对应的准备过程时长相同。
可以理解，终端基于N个传输中的第一传输，确定N个触发发射通道切换的传输对应的第一时域位置T0和准备过程时长T_offset，且各个传输对应的第一时域位置均相同，各个传输对应的准备过程时长也相同，从而可以保证Tx切换过程中的正常传输，减少终端复杂度，提高吞吐量。
可选地，所述准备过程时长与以下至少一项有关：
所述第一传输所在的载波的子载波间隔；
调度或配置所述第一传输的第一信息所在的载波的子载波间隔；
第一时间窗口内的用于调度或配置所述N个传输中各个传输的信息所在的载波的子载波间隔；
所述第一时间窗口内调度或配置的所述N个传输所在的载波的子载波间隔；
所述第一时间窗口内调度或配置的所述N个传输对应的天线端口数量；
配置的发射通道切换的模式。
可选地，所述准备过程时长T_offset的值和配置的Tx切换模式有关，例如只有当配置为dualUL时，DCI调度的传输(Tx切换后)所在的载波的上行SCS为配置的所有载波的SCS的最小值或最大值。
可选地，所述准备过程时长T_offset根据所述第一时间窗口内的至少部分信息对应的发射通道切换前后的载波的子载波间隔确定。
可选地，根据所述第一时间窗口内的至少部分信息对应的Tx切换前后的载波的SCS确定的准备过程时长T_offset，为所述至少部分信息中每个信息得到的T_offset中的最大值/最小值。
可选地，所述准备过程时长根据所述第一时间窗口内的至少部分信息对应的发射通道切换前后的载波的子载波间隔确定，包括：
所述准备过程时长根据所述至少部分信息中各信息所在的下行载波的子载波间隔，以及所述至少部分信息中各信息调度或配置的传输所在的载波的上行子载波间隔确定。
可以理解的是，准备过程时长根据至少部分信息中各信息所在的下行载波的SCS，和至少部分信息中各信息调度/配置的传输(Tx切换后)所在的载波的上行SCS(如果调度多个载波，则为多个载波的SCS的最大值或最小值)确定。
例如，所述确定的准备过程时长T_offset为每个DCI得到的T_offset中的最大值/最小值。第一时间窗口内满足第一条件的每个DCI根据Tx切换前后的载波的SCS，得到一个T_offset的值。具体为由DCI所在的下行载波的SCS，和DCI调度的传输(Tx切换后)所在的载波的上行SCS(如果调度多个载波，则为多个载波的SCS的最大值或最小值)确定，参考如下公式，求得Tproc,2的值即T_offset的值：
Tproc,2＝max((N2+d2,1)(2048+144)·κ2-μ·TC+Tswitch,d2,2)
如果传输块的PUSCH分配中的第一个上行链路符号，包括UE专用解调参考信号(UE-specific DeModulation Reference Signal,DM-RS)，由时隙偏移K2和Koffset(如果已配置)定义，并且PUSCH分配的开始S和长度L由“时域资源”指示调度DCI的分配，包括时间提前的影响，不早于符号L2，其中L2定义为下一个上行符号，其CP在接收到承载调度PUSCH的DCI的PDCCH的最后一个符号结束之后开始，则UE应发送传输块。当PDCCH候选与配置了searchSpaceLinking的搜索空间集合相关联时，为了确定承载调度PUSCH的DCI的PDCCH的最后一个符号，使用配置的两个PDCCH候选中时间较晚结束的PDCCH候选。
N2分别基于表6.4-1和表6.4-2中UE处理能力1和2的μ，其中，μ对应于Tproc,2最大时的一个(μDL,μUL)，其中μDL对应于传输承载DCI调度PUSCH的PDCCH的下行链路的子载波间隔，μUL对应于要传输PUSCH的上行链路信道的子载波间隔，并且，κ在[4,TS 38.211]的第4.1节中定义。
如果PUSCH分配的第一个符号仅包含DM-RS，则d2,1＝0，否则，d2,1＝1。
如果UE配置有多个活动分量载波，则PUSCH分配中的第一个上行链路符号还包括在[11,TS 38.133]中给出的分量载波之间的时间差的影响。
如果调度DCI触发了BWP的切换，则d2,2等于[11,TS 38.133]中定义的切换时间，否则d2,2＝0。
