Description

一种上行信道传输方法、终端及基站
相关申请的交叉引用
本申请要求于2019年12月06日提交的申请号为201911243473.3发明名称为“一种上行信道传输方法、终端及基站”的中国专利申请的优先权，其通过引用方式全部并入本文。
技术领域
本申请涉及通信技术领域，尤其涉及一种上行信道传输方法、终端及基站。
背景技术
在5G新空口(New Radio，NR)中，不支持物理上行控制信道(Physical Uplink Control Channel，PUCCH)和物理上行共享信道(Physical Uplink Shared Channel，PUSCH)同时传输(时域资源重叠)，也不支持多个存在重叠的PUCCH在同一个载波上同时传输。PUCCH用于承载上行控制信息(Uplink Control Information，UCI)，UCI可以包括混合自动重传请求确认字符(Hybrid Automatic Repeat request-Acknowledge character，HARQ-ACK)、信道状态信息(Channel State Information，CSI)和调度请求(Scheduling Request，SR)中的一种或多种组合。
当出现PUCCH和PUSCH的全部或部分符号存在重叠时，需要对PUCCH和PUSCH中起始最早的信道的第一个符号判断是否满足预先定义的时间条件(timeline)。当满足时，则将PUCCH上承载的UCI转移到PUSCH上传输，从而不再传输PUCCH，从而避免PUCCH和PUSCH的同时传输。如果同时存在多个PUSCH与PUCCH重叠，则在多个PUSCH中按照预定的规则选择一个PUSCH，例如优先选择承载非周期性信道状态信息(A-CSI)的PUSCH(如果存在)；如果没有承载A-CSI的PUSCH，则优先选择具有对应的物理下行控制信道(Physical Downlink Control Channel，PDCCH)的PUSCH；当多个载波上同时存在相同类型的PUSCH时(例如都是具有对应的PDCCH的PUSCH，或在没有具有对应的PDCCH 的PUSCH时，都是没有具有对应的PDCCH的PUSCH)，选择载波编号最小的载波上的PUSCH，如果在选择的载波上存在多个PUSCH与PUCCH重叠，则选择时间最早的PUSCH。
当承载UCI的PUCCH之间在时域上存在重叠时，同样需要对重叠的PUCCH中起始最早的信道的第一个符号判断是否满足预先定义的时间条件。当满足时，可以对多个PUCCH上的UCI进行组合传输，组合在一个PUCCH信道上传输，从而避免多个PUCCH并行传输。在R15中定义不会出现不满足timeline的情况，即不满足timeline的情况为错误调度，没有执行行为，相应的基站在调度和配置时，需要保证重叠信道之间总是满足timeline。
但是，当上行信道存在重叠时，重叠的上行信道可能存在部分信道因为其所占用的符号集合中存在不可用符号而导致这个信道不能传输，此时如何进行上行信道传输还没有明确方案。

具体实施方式
为使本申请实施例的目的、技术方案和优点更加清楚，下面将结合本申请实施例中的附图，对本申请实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例是本申请一部分实施例，而不是全部的实施例。基于本申请中的实施例，本领域普通技术人员在没有作出创造性劳动前提下所获得的所有其他实施例，都属于本申请保护的范围。
具体的，在5G NR中不支持PUCCH和PUSCH同时传输(时域资源重叠)，也不支持多个存在重叠的PUCCH在同一个载波上同时传输。此时两个PUCCH之间重叠时，复用传输规则可以如下：
1)当承载SR的PUCCH与承载HARQ-ACK的PUCCH重叠且承载HARQ-ACK的PUCCH使用PUCCH格式(format)0，承载SR的PUCCH可以使用format 0也可以使用format 1时，在HARQ-ACK的PUCCH资源上复用传输SR和HARQ-ACK，即通过在HARQ-ACK的PUCCH资源上，通过选择使用对应存在正SR还是负SR时HARQ-ACK对应的循环移 位(Cyclic Shift，CS)来传输HARQ-ACK，隐含表达SR为正(positive)还是负(negative)。
2)当承载SR的PUCCH与承载HARQ-ACK的PUCCH重叠，且承载SR的PUCCH使用format 0，承载HARQ-ACK的PUCCH使用format 1时，丢弃(drop)SR，即此时不进行复用传输。
3)当承载SR的PUCCH与承载HARQ-ACK的PUCCH重叠，且承载SR的PUCCH使用format 1，承载HARQ-ACK的PUCCH使用format 1时，当存在positive SR时，HARQ-ACK在SR的PUCCH资源上传输，从而通过使用SR对应的PUCCH资源传输HARQ-ACK来隐式表达同时存在SR传输，否则(即negative SR)，HARQ-ACK在HARQ-ACK的PUCCH资源上传输。
4)当承载SR的PUCCH与承载HARQ-ACK的PUCCH重叠，且承载HARQ-ACK的PUCCH使用format 2或3或4，承载SR的PUCCH可以使用format0也可以使用format1时，根据SR和HARQ-ACK的总比特数确定一个PUCCH资源集合，根据HARQ-ACK对应的(Downlink Control Information，DCI)中的PUCCH资源指示域，在确定的一个PUCCH资源集合中确定一个PUCCH资源，用于同时传输SR和HARQ-ACK，其中，SR为X比特，表示与HARQ-ACK重叠的X个SR中的SR状态(哪个为positive，或者都为negative)，即不论SR为positive还是negative，总是要传输X比特SR，以避免由于SR状态导致HARQ-ACK的PUCCH资源上传输的UCI比特数的变化。
5)当承载半持续调度(Semi-Persistent Scheduling，SPS)HARQ-ACK(即对应SPS PDSCH的HARQ-ACK，也即没有对应的PDCCH的HARQ-ACK)和/或SR的PUCCH，与承载CSI的PUCCH重叠时，将SPS HARQ-ACK和/或SR转移到CSI对应的PUCCH资源上与CSI复用传输。
6)当承载有对应的PDCCH(即当HARQ-ACK为PDSCH的反馈信息时，调度PDSCH的PDCCH与HARQ-ACK对应，当HARQ-ACK为指示下行SPS资源释放的PDCCH的反馈信息时，该PDCCH与HARQ-ACK对应)的HARQ-ACK的PUCCH与承载CSI的PUCCH重叠时，根据HARQ-ACK和CSI的总比特数，在多个PUCCH资源集合中选择一个 PUCCH资源集合，再根据HARQ-ACK对应的DCI中的PUCCH资源指示域从选择的一个PUCCH资源集合中确定出一个PUCCH资源，用于同时承载HARQ-ACK和CSI；此时重新确定的PUCCH资源与原承载HARQ-ACK的PUCCH资源可能相同或者不同(如果不同，即为一个新的PUCCH资源)。终端不期待仅被配置了一个PUCCH资源集合时被配置支持HARQ-ACK和CSI同时传输。
当存在超过2个PUCCH之间的重叠时，假设一个时隙中的PUCCH构成集合Q，确定该集合Q中起始时间最早的上行信道作为信道A，确定与信道A存在重叠的信道集合X；对信道A和信道X上的UCI按照上述复用传输规则得到一个用于复用传输的信道资源，用这个复用传输的信道资源替换集合Q中的信道A和信道X，继续上述步骤在新的Q集合中确定信道A和信道X，以此类推，直到得到多个时域上不重叠的PUCCH。
上述对于重叠的多个PUCCH或重叠的PUCCH和PUSCH中，在其中一个PUCCH或PUSCH具有对应的DCI时(例如PUCCH承载的HARQ-ACK为具有DCI调度的PDSCH的HARQ-ACK或为指示下行SPS资源释放的DCI，则该调度PDSCH的DCI或指示下行SPS资源释放的DCI为PUCCH对应的DCI，例如调度PUSCH的DCI为PUSCH对应的DCI)，重叠信道中的起始最早的信道(如果起始相同，则随便选一个信道)的第一个符号需要满足如下timeline：
Timeline1：第一个符号不早于在任何一个需要在PUCCH上进行HARQ-ACK反馈的PDSCH或SPS PDSCH释放(release)的最后一个符号之后的T1时间之后起始的一个包括循环前缀(Cyclic Prefix，CP)在内的符号，即第一个符号与任何一个上述PDSCH或SPS PDSCH release的最后一个符号之间的时间间隔不少于T1时间，T1与PDSCH或SPS PDSCH release的处理时延有关，可以根据公式和相关的参数计算得到；该timeline的目的是保证在最终确定的传输HARQ-ACK的信道的传输开始之前，能够完成对HARQ-ACK的获取和准备。
Timeline2：第一个符号不早于调度PDSCH(如果有)和PUSCH(如果有)的任意一个PDCCH(包括指示SPS PDSCH release的PDCCH)的最后一个符号之后的T2时间之后起始的一个包括CP在内的符号，即第一 个符号与任何一个上述PDCCH的最后一个符号之间的时间间隔不少于T2时间，T2与PUSCH的处理时延有关，可以根据公式和相关的参数计算得到。该timeline的目的是保证当存在多种UCI复用传输时，多种UCI可以在传输UCI的目标信道的传输开始之前，完成各种UCI的获取和复用处理。
例如如图1-1至图1-4(即图1-1、图1-2、图1-3和图1-4)所示，如果同时存在调度PDSCH的PDCCH(图中的DL DCI)和调度PUSCH的PDCCH(图中的UL DCI)，则第一个符号和所有PDCCH的最后一个符号之间都需要满足T2间隔，实际上等效于与最后一个PDCCH之间满足T2间隔即可，而如果同时存在多个PDSCH时，第一个符号与所有PDSCH的最后一个符号之间都需要满足T1间隔，实际上等效于与最后一个PDSCH之间满足T1间隔即可。当然，上述timeline的使用也不限定于图1-1至图1-4所示的场景。对于图1-3和图1-4，如果PUCCH承载的HARQ-ACK没有对应的DCI(即HARQ-ACK为SPS PDSCH的HARQ-ACK)，此时没有图中的DL DCI，则仅需要核查(check)T1不需要check T2。对于图1-1和图1-2，如果PUCCH承载的HARQ-ACK没有对应的DCI(即HARQ-ACK为SPS PDSCH的HARQ-ACK)，此时没有图中的DL DCI，如果PUSCH也没有对应的DCI，此时没有图中的UL DCI，则仅需要check T1不需要check T2。如果PUCCH与PUSCH重叠，且PUCCH上承载的是CSI和/或SR，则不需要check T1，进一步如果PUSCH没有对应的DCI，则也不需要check T2。
此外，如果是承载CSI的PUSCH，在同一个载波上、在时域上存在重叠，根据承载的CSI的优先级不同进行选择，选择一个承载较高优先级CSI的PUSCH进行传输，丢弃承载低优先级CSI的PUSCH，其中CSI可以包括非周期CSI(A-CSI)、半持续CSI(SP-CSI)、周期CSI(P-CSI)，优先级从高到低依次可以为A-CSI、SP-CSI、P-CSI。
通过上述复用传输规则虽然能够实现存在重叠的上行信道之间不同时传输，但是重叠的上行信道中可能存在部分信道因为其所占用的符号集合中存在不可用符号而导致这个信道不能传输，此时如何对重叠的上行信道进行处理，解决重叠传输问题还没有明确的方法。
针对此，本申请给出了具体实现方式，下面对本申请实施例进行具体介绍。
当存在多个上行信道在时域上重叠时，终端侧可以通过如下两种处理方式中的任一一种方式进行上行信道的传输：
方式一：参见图2，该方式包括如下步骤：
步骤201：先基于信道复用传输规则对多个上行信道进行处理，确定待传输的第一目标上行信道，然后确定是否对第一目标上行信道进行传输。
在该方式中，具体的，通过先基于信道复用传输规则对多个上行信道进行处理，确定待传输的第一目标上行信道，然后确定是否对第一目标上行信道进行传输，明确了基于信道复用传输规则对多个上行信道进行处理的过程以及是否对上行信道进行传输的判断过程之间的先后顺序，从而使得终端能够直接依据该顺序明确上行信道的传输情况，保证了系统的正常传输。
此外，具体的，在此需要说明的是，基于信道复用传输规则对多个上行信道进行处理的过程可以参见上述对复用传输规则的说明过程，在此不再进行赘述。
方式二：参见图3，该方式包括如下步骤：
步骤301：先从多个上行信道中确定能够进行传输的候选上行信道，然后基于信道复用传输规则对候选上行信道进行处理，确定待传输的第二目标上行信道。
在该方式中，具体的，通过先从多个上行信道中确定能够进行传输的候选上行信道，然后基于信道复用传输规则对候选上行信道进行处理，确定待传输的第二目标上行信道，明确了是否对上行信道进行传输的判断过程和基于信道复用传输规则对多个上行信道进行处理的过程之间的先后顺序，从而使得终端能够直接依据该顺序明确上行信道的传输情况，保证了系统的正常传输。
具体的，在此需要说明的是，基于信道复用传输规则对候选上行信道进行处理的过程可以参见上述对复用传输规则的说明过程，在此不再进行赘述。
即本实施例在多个上行信道在时域上存在重叠时，通过设置先基于信 道复用传输规则对多个上行信道进行处理，确定待传输的第一目标上行信道，然后确定是否对第一目标上行信道进行传输的顺序，或者先从多个上行信道中确定能够进行传输的候选上行信道，然后基于信道复用传输规则对候选上行信道进行处理，确定待传输的第二目标上行信道的顺序，使得终端能够基于确定的是否对上行信道进行传输的判断过程和基于信道复用传输规则对多个上行信道进行处理的过程之间的先后顺序，明确上行信道的传输情况，从而保证了系统的正常传输，提升了系统传输性能。
此外，下面对确定是否对上行信道进行传输的过程进行说明。
其中，在方式一中，在确定是否对第一目标上行信道进行传输时，可以检测第一目标上行信道传输所在的符号集合中是否包含第一不可用符号，此时当第一目标上行信道传输所在的符号集合中不包含第一不可用符号时，确定对第一目标上行信道进行传输。
当然，当第一目标上行信道传输所在的符号集合中包含第一不可用符号时，确定不对第一目标上行信道进行传输。
具体的，该第一不可用符号可以包括下述符号中的至少一项：
高层信令配置的下行(简称DL)符号、高层信令配置的灵活(简称FL)符号、DCI调度进行下行传输的符号、用于指示时间单元结构的DCI中的指示信息指示为DL的符号或指示为FL的符号、保护间隔(简称GP)所占用的符号、同步信号传输块(简称SSB)传输所占用的符号、信令预先配置的不可用符号、处于带宽部分(简称BWP)切换时间中的符号。
此外，具体的，用于指示时间单元结构的DCI为用于承载指示上下行结构的指示信息的DCI，例如使用时隙格式指示符-无线网络临时标识(简称SFI-RNTI)加扰的DCI格式2-0。
另外，具体的，DCI调度进行下行传输的行为可以包括：由DCI格式1_0、DCI格式1_1或者DCI格式0_1指示终端接收PDSCH或信道状态信息参考信号(简称CSI-RS)的行为。
此外，在上述方式二中，从多个上行信道中确定能够进行传输的候选上行信道时，同样可以针对多个上行信道中的每个上行信道，检测上行信道传输所在的符号集合中是否包含第二不可用符号，此时当上行信道传输所在的符号集合中不包含第二不可用符号时，可以将上行信道确定为候选 上行信道。
当然，当上行信道传输所在的符号集合中包含第二不可用符号时，该上行信道不能为候选上行信道。
具体的，第二不可用符号同样可以包括下述符号中的至少一项：
高层信令配置的DL符号、高层信令配置的FL符号、DCI调度进行下行传输的符号、用于指示时间单元结构的DCI中的指示信息指示为DL的符号或指示为FL的符号、GP所占用的符号、SSB传输所占用的符号、信令预先配置的不可用符号、处于BWP切换时间中的符号。
在此需要说明的是，对于DCI以及DCI调度进行的下行传输可以参见第一不可用符号中对DCI以及DCI调度进行的下行传输的介绍，在此不再进行赘述。
进一步地，在方式二中，在确定待传输的第二目标上行信道之后，还可以确定是否对第二目标上行信道进行传输。
具体的，在确定是否对第二目标上行信道进行传输时，可以检测第二目标上行信道传输所在的符号集合中是否包含第三不可用符号，此时当第二目标上行信道传输所在的符号集合中不包含第三不可用符号时，确定对第三目标上行信道进行传输。
当然，当第二目标上行信道传输所在的符号集合中包含第三不可用符号时，确定不对第二目标上行信道进行传输。
具体的，该第三不可用符号可以包括下述符号中的至少一项：
高层信令配置的DL符号、高层信令配置的FL符号、DCI调度进行下行传输的符号、用于指示时间单元结构的DCI中的指示信息指示为DL的符号或指示为FL的符号、GP所占用的符号、SSB传输所占用的符号、信令预先配置的不可用符号、处于BWP切换时间中的符号。
在此需要说明的是，对于DCI以及DCI调度进行的下行传输可以参见第一不可用符号中对DCI以及DCI调度进行的下行传输的介绍，在此不再进行赘述。
还需要说明的是，第一不可用符号和第二不可用符号可以相同，也可以不同，在此不进行具体限定；此外，第二不可用符号和第三不可用符号可以相同，也可以不同，在此同样不进行具体限定。
例如，第一不可用符号可以至少包括高层信令配置的DL符号、DCI调度进行下行传输的符号、用于指示时间单元结构的DCI中的指示信息指示为DL的符号或指示为FL的符号、SSB传输所占用的符号；而第二不可用符号可以同第一不可用符号相同，或者第二不可用符号至少包括高层信令配置的DL符号和SSB传输所占用的符号；第三不可用符号至少包括高层信令配置的DL符号、DCI调度进行下行传输的符号、用于指示时间单元结构的DCI中的指示信息指示为DL的符号或指示为FL的符号、SSB传输所占用的符号。
另外，进一步地，还需要说明的是，本实施例中的多个上行信道中至少包括一个由高层信令配置进行传输的信道，即半静态信道。
此时，在上述第一种方式中，在确定是否对所述第一目标上行信道进行传输时，可以检测该第一目标上行信道是否为由高层信令配置进行传输的信道，并当第一目标上行信道为由高层信令配置进行传输的信道时，确定是否对第一目标上行信道进行传输。
此外，在上述第二种方式中，在从多个上行信道中确定能够进行传输的候选上行信道时，可以从由高层信令配置进行传输的信道中确定能够进行传输的候选上行信道。
并且，在确定是否对第二目标上行信道进行传输时，可以检测该第二目标上行信道是否为由高层信令配置进行传输的信道，并当该第二目标上行信道为由高层信令配置进行传输的信道时，再确定是否对第二目标上行信道进行传输。
具体的，该由高层信令配置进行传输的信道可以包括如下信道中的至少一种：未对应PDCCH的PUSCH、使用SPS对应的PUCCH资源传输的PUCCH、使用CSI对应的PUCCH资源传输的PUCCH、使用SR对应的PUCCH资源传输的PUCCH。
具体的，未对应PDCCH的PUSCH可以包括小区组PUSCH(简称CG PUSCH)和承载半持续信道状态信息(简称SP-CSI)的PUSCH。此外，使用SPS对应的PUCCH资源传输的PUCCH包括承载SPS PDSCH的HARQ-ACK的PUCCH。
这样，本实施例在多个上行信道在时域上存在重叠时，通过规定是否 对上行信道进行传输的判断过程和基于信道复用传输规则对多个上行信道进行处理的过程之间的先后顺序，使得终端能够明确上行信道的传输情况，从而保证了系统的正常传输，提升了系统传输性能。
此外，当存在多个上行信道在时域上重叠时，基站侧可以通过如下两种处理方式中的任一一种方式进行上行信道的传输：
方式一：参见图4，该方式包括如下步骤：
步骤401：先基于信道复用传输规则对多个上行信道进行处理，确定待接收的第一目标上行信道，然后确定是否对第一目标上行信道进行接收。
在该方式中，具体的，通过先基于信道复用传输规则对多个上行信道进行处理，确定待接收的第一目标上行信道，然后确定是否对第一目标上行信道进行接收，明确了基于信道复用传输规则对多个上行信道进行处理的过程以及是否对上行信道进行接收的判断过程之间的先后顺序，从而使得基站能够直接依据该顺序明确上行信道的接收情况，避免了两个过程顺序不清楚导致的终端和基站对传输情况的理解不一致的问题，保证了系统的正常传输。
当然，在此需要说明的是，在该种方式下，终端同样采用该方式确定上述两个过程的先后顺序，即对应的，终端先基于信道复用传输规则对多个上行信道进行处理，确定待传输的第一目标上行信道，然后确定是否对第一目标上行信道进行传输，从而实现终端和基站对传输情况的理解一致性，保证系统的正常传输。
还需要说明的是，基于信道复用传输规则对多个上行信道进行处理的过程可以参见上述对复用传输规则的说明过程，在此不再进行赘述。
方式二：参见图5，该方式包括如下步骤：
步骤501：先从多个上行信道中确定能够进行传输的候选上行信道，然后基于信道复用传输规则对候选上行信道进行处理，确定待接收的第二目标上行信道。
在该方式中，具体的，通过先从多个上行信道中确定能够进行传输的候选上行信道，然后基于信道复用传输规则对候选上行信道进行处理，确定待接收的第二目标上行信道，明确了是否对上行信道进行接收的判断过程和基于信道复用传输规则对多个上行信道进行处理的过程之间的先后 顺序，从而使得终端能够直接依据该顺序明确上行信道的接收情况，避免了两个过程顺序不清楚导致的终端和基站对传输情况的理解不一致的问题，保证了系统的正常传输。
当然，在此需要说明的是，在该种方式下，基站同样采用该方式确定上述两个过程的先后顺序，即对应的，终端先从多个上行信道中确定能够进行传输的候选上行信道，然后基于信道复用传输规则对候选上行信道进行处理，确定待传输的第二目标上行信道，从而实现终端和基站对传输情况的理解一致性，保证系统的正常传输。
还需要说明的是，基于信道复用传输规则对候选上行信道进行处理的过程可以参见上述对复用传输规则的说明过程，在此不再进行赘述。
此外，进一步地，下面对确定是否对上行信道进行接收的过程进行说明。
在方式一中，在确定是否对第一目标上行信道进行接收时，可以检测第一目标上行信道传输所在的符号集合中是否包含第一不可用符号，并当第一目标上行信道传输所在的符号集合中不包含第一不可用符号时，确定对第一目标上行信道进行接收。
具体的，该第一不可用符号可以包括下述符号中的至少一项：
高层信令配置的下行(简称DL)符号、高层信令配置的灵活(简称FL)符号、DCI调度进行下行传输的符号、用于指示时间单元结构的DCI中的指示信息指示为DL的符号或指示为FL的符号、保护间隔(简称GP)所占用的符号、同步信号传输块(简称SSB)传输所占用的符号、信令预先配置的不可用符号、处于带宽部分(简称BWP)切换时间中的符号。
在此需要说明的是，对于DCI以及DCI调度进行的下行传输可以参见终端侧第一不可用符号中对DCI以及DCI调度进行的下行传输的介绍，在此不再进行赘述。
在方式二中，从多个上行信道中确定能够进行传输的候选上行信道时，可以针对多个上行信道中的每个上行信道，检测上行信道传输所在的符号集合中是否包含第二不可用符号，此时当上行信道传输所在的符号集合中不包含第二不可用符号时，可以将上行信道确定为候选上行信道。
具体的，第二不可用符号同样可以包括下述符号中的至少一项：
高层信令配置的DL符号、高层信令配置的FL符号、DCI调度进行下行传输的符号、用于指示时间单元结构的DCI中的指示信息指示为DL的符号或指示为FL的符号、GP所占用的符号、SSB传输所占用的符号、信令预先配置的不可用符号、处于BWP切换时间中的符号。
在此需要说明的是，对于DCI以及DCI调度进行的下行传输可以参见终端侧第一不可用符号中对DCI以及DCI调度进行的下行传输的介绍，在此不再进行赘述。
此外，进一步地，在方式二中，在确定待接收的第二目标上行信道之后，还需要确定是否对第二目标上行信道进行接收。
具体的，在确定是否对第二目标上行信道进行接收时，可以检测第二目标上行信道传输所在的符号集合中是否包含第三不可用符号，并当第二目标上行信道传输所在的符号集合中不包含第三不可用符号时，确定对第二目标上行信道进行接收。
具体的，该第三不可用符号包括下述符号中的至少一项：
高层信令配置的DL符号、高层信令配置的FL符号、DCI调度进行下行传输的符号、用于指示时间单元结构的DCI中的指示信息指示为DL的符号或指示为FL的符号、GP所占用的符号、SSB传输所占用的符号、信令预先配置的不可用符号、处于BWP切换时间中的符号。
还需要说明的是，第一不可用符号和第二不可用符号可以相同，也可以不同，在此不进行具体限定；此外，第二不可用符号和第三不可用符号可以相同，也可以不同，在此同样不进行具体限定。此外，对第一不可用符号、第二不可用符号和第三不可用符号的举例可以参见终端侧，在此不再进行具体介绍。
另外，进一步地，还需要说明的是，本实施例中的多个上行信道中至少包括一个由高层信令配置进行传输的信道，即半静态信道。
此时，在上述第一种方式中，在确定是否对第一目标上行信道进行接收时，可以检测该第一目标上行信道是否为由高层信令配置进行传输的信道，并当第一目标上行信道为由高层信令配置进行传输的信道时，确定是否对第一目标上行信道进行接收。
此外，在上述第二种方式中，在从多个上行信道中确定能够进行传输 的候选上行信道时，可以从由高层信令配置进行传输的信道中确定能够进行传输的候选上行信道。
并且，在确定是否对第二目标上行信道进行接收时，可以检测该第二目标上行信道是否为由高层信令配置进行传输的信道，并当该第二目标上行信道为由高层信令配置进行传输的信道时，确定是否对第二目标上行信道进行接收。
具体的，该由高层信令配置进行传输的信道包括如下信道中的至少一种：未对应PDCCH的PUSCH、使用SPS对应的PUCCH资源传输的PUCCH、使用CSI对应的PUCCH资源传输的PUCCH、使用SR对应的PUCCH资源传输的PUCCH。
具体的，对于PUSCH以及使用SPS对应的PUCCH资源传输的PUCCH的介绍可以参见终端侧，在此不再进行赘述。
这样，本实施例在多个上行信道在时域上存在重叠时，通过规定是否对上行信道进行接收的判断过程和基于信道复用传输规则对多个上行信道进行处理的过程之间的先后顺序，使得基站能够明确上行信道的传输情况，避免了在上行信道存在重叠时两个过程先后顺序不清楚导致的终端和基站对传输情况理解不一致的问题，从而保证了系统的正常传输，提升了系统传输性能。
下面通过具体实施例对上述过程进行说明。
实施例一：
在CC1(Component Carrier，载波单元)和CC2上分别存在一个PUCCH和一个PUSCH传输，且PUCCH和PUSCH在时域上存在重叠，其中，PUCCH上承载SPS PDSCH的HARQ-ACK(简称SPS HARQ-ACK)，PUSCH没有对应的PDCCH(即CG PUSCH)，则：
若终端和基站约定使用上述中的方式一，假设高层信令配置的DL符号、DCI调度进行下行传输的符号、用于指示时间单元结构的DCI中的指示信息指示为DL或FL的符号以及SSB传输占用的符号都为不可用符号，则：在终端侧，先根据PUCCH和PUSCH重叠的复用传输规则，确定PUCCH上的HARQ-ACK转移到PUSCH上传输，从而不传输PUCCH，即得到最终传输的信道为PUSCH，然后，判断PUSCH是否包含不可用符 号，由于PUSCH为全UL符号，不包含不可用符号，从而传输这个PUSCH，具体如图6-1所示；在基站侧，按照同终端侧相一致的方式确定终端将HARQ-ACK转移到PUSCH上传输，从而在CC2上接收PUSCH并获得其中的HARQ-ACK，而不在CC1上接收PUCCH即可。
若终端和基站约定使用上述中的方式二，假设判断每个信道是否包含不可用符号时，高层信令配置的DL符号以及SSB传输占用的符号为不可用符号，判断最终传输的信道是否包含不可用符号时，不可用符号的定义同方式一，则：在终端侧，先判断每个信道是否包含不可用符号，PUCCH包含DL符号因此包含不可用符号，从而确定PUCCH不能传输，则意味着丢弃了PUCCH上承载的HARQ-ACK，PUSCH为全UL符号，不包含不可用符号，这样就不存在PUCCH和PUSCH的重叠了，直接在CC2上传输PUSCH，具体如图6-2所示；在基站侧，按照同终端侧相一致的方式确定终端仅传输PUSCH，从而在CC2上接收PUSCH，而不在CC1上接收PUCCH即可，进一步，基站可以将对应被丢弃的HARQ-ACK的下行传输进行重传。
当然在此需要说明的是，在该实施例中仅以PUCCH包含不可用符号为例进行说明，如果PUSCH包含不可用符号，而PUCCH不包含，则上述方法同样适用，只不过最终结果是传输PUCCH，不传输PUSCH。
实施例二：
在CC1、CC2和CC3上分别存在一个PUCCH和一个PUSCH传输，且PUCCH和两个PUSCH在时域上都存在重叠，其中，PUCCH上承载SPS HARQ-ACK，两个PUSCH都为CG PUSCH，则：
若终端和基站约定使用上述中的方式一，假设高层信令配置的DL符号、DCI调度进行下行传输的符号、DCI格式2-0指示为DL或FL的符号以及SSB传输占用的符号都为不可用符号，则：在终端侧，先根据PUCCH和PUSCH重叠的复用传输规则，确定PUCCH上的HARQ-ACK转移到一个PUSCH上传输，从而不传输PUCCH，由于存在两个PUSCH与PUCCH重叠，需要选择出一个PUSCH，根据现有技术中的选择规则(选择顺序从先到后依次为A-CSI PUSCH>有对应PDCCH的PUSCH>CG PUSCH，对于上述同一类PUSCH，如果在多个CC上，则选择CC编号最小的CC 上的PUSCH，如果在一个CC上存在时分复用(简称TDM)的多个同类的PUSCH，选择时间靠前的PUSCH)，选择CC2上的PUSCH用于承载HARQ-ACK，即得到最终传输的信道为CC2上的承载HARQ-ACK的PUSCH和CC3上的PUSCH，然后，判断CC2和CC3上的PUSCH是否包含不可用符号，对于CC2上承载HARQ-ACK的PUSCH，由于包含DL符号，判断这个PUSCH包含不可用符号，从而不传输这个PUSCH，相应的转移到这个PUSCH上的HARQ-ACK也被丢弃，对于CC3上的PUSCH，如果其传输所包含的FL符号为不可用符号(例如对于这个FL符号，其上存在DCI调度的下行传输，和/或，DCI格式2-0指示其为DL或FL)，则确定CC3上的PUSCH不传输，如果其传输所包含的FL符号不是不可用符号，则在CC3上传输PUSCH，具体如图6-3所示；在基站侧，按照同终端侧相一致的方式确定终端的传输行为，从而在相应的CC上进行相应的接收。
若终端和基站约定使用上述中的方式二：
第一种情况，假设不可用符号定义1，为高层信令配置的DL符号以及SSB传输占用的符号为不可用符号，用于判断每个信道是否包含不可用符号，不可用符号定义2为同方式一，用于判断最终传输的信道是否包含不可用符号，则：在终端侧，先根据不可用符号定义1，判断每个存在重叠的半静态信道是否包含不可用符号，PUCCH和CC3上的PUSCH由于不包含DL符号或SSB符号，即不包含不可用符号，CC2上的PUSCH由于包含DL符号，即包含不可用符号，从而确定不能传输，则确定可以传输的信道为PUCCH和CC3上的PUSCH，对这两个重叠信道使用复用传输规则，即PUCCH上的HARQ-ACK转移到CC3上的PUSCH中传输，再对最终传输的CC3上的PUSCH基于不可用符号定义2判断是否包含不可用符号，由于CC3上的PUSCH包含FL符号，这里取决于FL符号是否可用，如果FL符号不可用(例如对于这个FL符号，其上存在DCI调度的下行传输，和/或，DCI格式2-0指示其为DL或FL)，判断这个PUSCH包含不可用符号，从而不传输这个PUSCH，相应的转移到这个PUSCH上的HARQ-ACK也被丢弃，具体如图6-4所示，如果FL符号可用，则在CC3上传输携带HARQ-ACK的PUSCH，具体如图6-5所示；在基站侧， 照同终端侧相一致的方式确定终端的传输行为，从而在相应的CC上进行相应的接收。
另一种情况，假定不可用符号不区分是对判断每个信道还是最终传输的信道(目标信道)，都定义为同方式一的不可用符号，则：在终端侧，先判断每个存在重叠的半静态信道是否包含不可用符号，PUCCH为全UL，不包含不可用符号，CC2上的PUSCH由于包含DL符号，包含不可用符号，CC3上的PUSCH由于包含FL，取决于FL符号是否可用，如果FL符号不可用(例如对于这个FL符号，其上存在DCI调度的下行传输，和/或，DCI格式2-0指示其为DL或FL)，则CC3上的PUSCH包含不可用符号，因此，确定CC2和3上的PUSCH都不能传输，则只有PUCCH可以传输，不存在上行信道重叠，终端在CC1上传输PUCCH即可，如图6-6所示，如果判断PUCCH由于不包含DL符号或SSB符号，即不包含不可用符号，则对PUCCH和CC3上的PUSCH进行复用传输，即将HARQ-ACK转移到CC3上的PUSCH上，从而不传输PUCCH，如图6-4所示；在基站侧，照同终端侧相一致的方式确定终端的传输行为，从而在相应的CC上进行相应的接收。
需要说明的是，上述实施例一和二中：PUCCH和PUSCH在不同载波仅为示例，当PUCCH和PUSCH在同一个载波上时，上述方法同样适用；PUCCH承载SPS HARQ-ACK仅为示例，当PUCCH承载其他UCI或者UCI组合时(如CSI，CSI+SR，SPS HARQ-ACK+CSI，SPS HARQ-ACK+SR，SPS HARQ-ACK+CSI+SR，将SPS HARQ-ACK替换为具有对应PDCCH的HARQ-ACK)，上述方法同样适用；当半静态UCI(如SPS HARQ-ACK、CSI、SR)替换为具有对应的PDCCH的HARQ-ACK时，可以不用判断这个PUCCH是否包含不可用符号，直接认为这个PUCCH总是可以传输的。
实施例三：
在CC1上存在一个承载HARQ-ACK的PUCCH和一个承载CSI的PUCCH，两个PUCCH之间存在重叠，HARQ-ACK为具有对应的PDCCH的PDSCH的反馈信息，则：
若终端和基站约定使用上述中的方式一：假设高层信令配置的DL符号、DCI调度进行下行传输的符号、用于指示时间单元结构的DCI中的指 示信息指示为DL或FL的符号以及SSB传输占用的符号都为不可用符号，则：在终端侧，先根据PUCCH重叠的复用传输规则，确定一个PUCCH资源用于同时传输HARQ-ACK和CSI，具体的根据HARQ-ACK和CSI的总比特数，在预先配置的多个PUCCH资源集合中选择一个，在选择的PUCCH资源集合中，根据HARQ-ACK对应的PDCCH中的PUCCH资源指示域确定一个PUCCH资源，这个PUCCH资源可能与原来承载HARQ-ACK的PUCCH资源相同或者不同，在这个资源上同时传输HARQ-ACK和CSI，具体如图6-7所示；由于这里的资源是PDCCH指示的，可以认为基站可以避免指示一个包含不可用符号的资源，因此，可以不用对这个资源判断是否包含不可用符号，或者认为总是不包含不可用符号；在基站侧，按照同终端侧相一致的方式得到最终的传输资源，从而在一个新确定的资源上同时接收HARQ-ACK和CSI。
若终端和基站约定使用上述中的方式二：假设判断每个信道是否包含不可用符号时，高层信令配置的DL符号以及SSB传输占用的符号为不可用符号，判断最终传输的信道是否包含不可用符号时，不可用符号的定义同方式一，则：在终端侧，先判断每个信道是否包含不可用符号，承载HARQ-ACK的PUCCH由于有对应的PDCCH，不认为包含不可用符号，承载CSI的PUCCH包含DL符号因此包含不可用符号，从而确定承载CSI的PUCCH不能传输，则意味着丢弃了PUCCH上承载的CSI，则不存在CSI与HARQ-ACK的重叠，直接传输承载HARQ-ACK的PUCCH即可，具体如图6-8所示；在基站侧，按照同终端侧相一致的方式确定终端仅传输承载HARQ-ACK的PUSCH，从而在HARQ-ACK对应的PUCCH资源上接收HARQ-ACK。
需要说明的是上述实施例三中，将有对应PDCCH的HARQ-ACK替换为SPS HARQ-ACK、SR中的一种，同样适用，将CSI替换为SPS HARQ-ACK、SR中的一种，同样适用，只不过需要替换对应的PUCCH重叠时的复用传输规则。
另外，在上述实施例一至三中，如果重叠的信道具有不同的优先级，并且复用传输规则为根据优先级选择传输高优先级信道，丢弃低优先级信道时，同样适用，例如实施例一中的情况，如果PUCCH的优先级高于 PUSCH，则：如果采用方式一，先进行复用，则丢弃PUSCH，认为只传输PUCCH，再对PUCCH进行是否包含不可用符号的判断，判断包含不可用符号，从而丢弃PUCCH，则最终两个信道都没有传输；如果采用方式二，先判断PUCCH包含不可用符号，不能传输，则仅剩PUSCH，虽然PUSCH优先级低于PUCCH，但还是可以传输PUSCH；其他实施例中同理，不再赘述；又例如将实施例三中的两个PUCCH替换为两个PUSCH，如果两个PUSCH优先级不同，复用规则为选择高优先级PUSCH，丢弃低优先级PUSCH时，执行过程同理，不再赘述。
还需要说明的是，上述实施例一至三中，图中的重叠情况仅为示例，其他传输长度和/或起点相同或不同的重叠情况，上述方法同样适用；上述实施例中的CG PUSCH替换为具有对应的PDCCH调度的PUSCH，则可以不用判断这个PUSCH是否包含不可用符号，直接认为这个PUSCH总是可以传输的，因为基于调度的PUSCH，基站总是知道哪些为不可用符号，原则上基站不应该调度这个PUSCH在包含不可用符号的符号集合中传输。
