技术领域

背景技术
在第五代新无线系统(5 Generation New RAT，5G NR)中，对于同一个终端会存在多个上行信道的时域资源重叠，例如PUCCH(Physical Uplink Control Channel，物理上行控制信道)和PUCCH存在时域资源重叠，或者PUCCH和PUSCH(Physical Uplink Shared Channel，物理上行共享信道)存在时域资源重叠。
在5G标准Rel-16版本中对于上行信道引入了两级物理层优先级的定义，也即上行支持两种不同物理层优先级的物理信道。当高优先级的物理信道和低优先级的物理信道在时域上重叠时，终端丢弃低优先级的物理信道，仅传输高优先级的物理信道，对上行控制信息的传输产生影响。

具体实施方式
本公开中术语“和/或”，描述关联对象的关联关系，表示可以存在三种关系，例如，A和/或B，可以表示：单独存在A，同时存在A和B，单独存在B这三种情况。字符“/”一般表示前后关联对象是一种“或”的关系。本公开实施例中术语“多个”是指两个或两个以上，其它量词与之类似。
在第五代新无线系统(5 Generation New RAT，5G NR)中，对于同一个终端会存在多个上行信道的时域资源重叠，例如PUCCH(Physical Uplink Control Channel，物理上行控制信道)和PUCCH存在时域资源重叠，或者PUCCH和PUSCH(Physical Uplink Shared Channel，物理上行共享信道)存在时域资源重叠。
在5G标准Rel-15版本中，对于同一个终端，为了避免出现过大的PAPR(Peak to Average Power Ratio，峰值平均功率比)，不支持多个PUCCH同时传输，也不支持PUCCH和PUSCH的同时传输，因此当PUCCH和PUCCH的时域资源重叠时，终端可以将UCI复用在同一个PUCCH上进行传输；当PUCCH和PUSCH的时域资源重叠时，终端可以将UCI复用在PUSCH上传输，从而不需要传输PUCCH。
当存在多个PUCCH和PUSCH的时域资源重叠时，终端以时隙为单位，首先处理一个时隙内的上行控制信道PUCCH之间的冲突，将一个时隙内所有的PUCCH作为Q集合，按照规定的方式进行复用，得到不重叠的一个或者多个PUCCH。然后再处理PUCCH和PUSCH的冲突，按照规定的方式将PUCCH承载的UCI复用在PUSCH上进行传输。
其中，上述时域资源重叠或冲突是指在同一个载波组中的冲突，例如双链接中的MCG和SCG各自为一个在载波组，例如支持PUCCH在SCG上传输时，会出现Primary PUCCH Group和Secondary PUCCH Group，每个PUCCH group为一个载波组。
而在5G标准Rel-16版本，在5G标准Rel-16版本中对于上行信道引入了两级物理层优先级的定义，也即上行支持两种不同物理层优先级的物理信道。当高优先级的物理信道和低优先级的物理信道在时域上重叠时，终端丢弃低优先级的物理信道，仅传输高优先级的物理信道。
对于HARQ-ACK(Hybrid Automatic Repeat request-ACKnowledgment，混合自动重传请求确认消息)传输，还引入了Sub-slot的传输方案，HARQ-ACK的PUCCH资源在Sub-slot范围内进行定义。一个时隙被划分为多个Sub-slot，不同优先级的 HARQ-ACK配置可以不同，比如，高优先级的HARQ-ACK使用基于Sub-slot的传输，低优先级的HARQ-ACK使用基于Slot的传输，或者高优先级的HARQ-ACK和低优先级的HARQ-ACK使用基于不同Sub-slot长度的传输。
当相同物理层优先级上行信道的时域资源重叠时，终端基于对应的配置信息确定复用的时间单元，并以该时间单元为单位，按照Rel-15的方式在该时间单元范围内进行相同物理层优先级上行信道的复用传输。
当同时存在相同和不同物理层优先级的上行信道冲突时，终端首先处理低优先级上行信道之间的复用，然后处理不同优先级之间的时域资源重叠，再处理高优先级上行信道之间的复用，最后再处理复用后的高优先级上行信道和低优先级上行信道之间的时域资源重叠，也即终端丢弃低优先级的物理信道，仅传输高优先级的物理信道。
为了降低不同物理层优先级的上行信道在时域重叠的情况下，丢弃低优先级上行信道的影响，目前正在研究将不同优先级的上行信道复用传输的方法，但是由于不同优先级的上行信道HARQ-ACK的传输时间单元可能不同，当多个不同传输时间单元的上行信道冲突时，目前还没有明确的复用传输方法。
针对上述技术问题，本公开实施例提供一种上行复用传输方法，对于终端或基站，在不同物理层优先级或不同类型的至少两个上行信道时域重叠的情况下，先确定复用过程的时间单元，例如基于高优先级HARQ-ACK的传输时间单元确定复用过程的时间单元，对于跨多个时间单元的目标上行信道，若未满足预设复用结束条件，则依次在与目标上行信道时域重叠的每一个时间单元中进行复用过程，直至满足预设复用结束条件，得到最终的复用过程的处理结果，例如对于低优先级PUCCH，在没有被丢弃且没有和其它上行信道复用的情况下参与和这个低优先级PUCCH时域重叠的每一个复用过程时间单元中的复用过程，最终基于复用过程的处理结果进行上行信道传输，可以在上行信道时域重叠的情况下减少丢弃某些上行信道产生的影响，例如对上行控制信息的传输产生影响。
本公开实施例提供的上行复用传输方法，可适用于如图1a所示的应用场景中，或者如图1b所示的应用场景中，该些应用场景中包括基站和终端(Terminal/User Equipment，UE)。
在图1a中，终端UE在不同物理层优先级或不同类型的至少两个上行信道时域重叠的情况下，确定复用过程的时间单元；对于至少两个上行信道中跨越多个时间单元的目标上行信道，若未满足预设复用结束条件，则依次在与目标上行信道时域重叠的每一个时间单元中进行复用过程，直至满足预设复用结束条件，得到最终的复用过程的处理结果；基于复用过程的处理结果与基站进行上行信道传输。
在图1b中，基站在不同物理层优先级或不同类型的至少两个上行信道时域重叠的情况下，确定复用过程的时间单元；对于至少两个上行信道中跨越多个时间单元的目标上行信道，若未满足预设复用结束条件，则依次在与目标上行信道时域重叠的每一个时间单元中进行复用过程，直至满足预设复用结束条件，得到最终的复用过程的处理结果；基于复用过程的处理结果接收终端UE通过上行信道传输的上行信息。
下面将结合本公开实施例中的附图，对本公开实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例仅仅是本公开一部分实施例，并不是全部的实施例。 基于本公开中的实施例，本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例，都属于本公开保护的范围。
其中，方法和装置是基于同一申请构思的，由于方法和装置解决问题的原理相似，因此装置和方法的实施可以相互参见，重复之处不再赘述。
图2为本公开一实施例提供的上行复用传输方法，该上行复用传输方法应用于终端或基站等网络设备，如图2所示，该方法具体步骤如下：
S201、在不同物理层优先级或不同类型的至少两个上行信道时域重叠的情况下，确定复用过程的时间单元。
在本实施例中，在5G标准Rel-16版本中对于上行信道引入了两级物理层优先级的定义，也即上行支持两种不同物理层优先级的物理信道，包括：高优先级(High Priority，HP)和低优先级(Low Priority，LP)上行信道。本实施例的前提条件是终端被配置支持不同优先级复用传输；如果存在不同物理层优先级的上行信道时域重叠时，需要进行复用过程，可先确定复用过程的时间单元，以便于在各复用过程的时间单元中进行上行信道的复用。
可选的，在时域重叠的不同物理层优先级的至少两个上行信道的情况下，在确定复用过程的时间单元时，由于不同物理层优先级的上行信道中HARQ-ACK的传输时间单元可能不同，因此可根据不同物理层优先级的HARQ-ACK的传输时间单元，确定所述复用过程的时间单元。
其中，HARQ-ACK的传输时间单元可以是时隙(Slot)或者子时隙(Sub-slot)，例如，HARQ-ACK的传输时间单元为子时隙时，子时隙长度可以是7个或6个OFDM符号，或者2个OFDM符号。
进一步的，本实施例中，可将不同物理层优先级中的高优先级HARQ-ACK的传输时间单元，确定为所述复用过程的时间单元。
在另一种实施例中，也可能存在不同类型的至少两个上行信道时域重叠的情况，例如MBS PUCCH和unicast PUCCH的时域冲突，需要进行复用过程，也可先确定复用过程的时间单元，以便于在各复用过程的时间单元中进行上行信道的复用。
具体的，在时域重叠的至少两个上行信道为不同类型的至少两个上行信道的情况下，在确定复用过程的时间单元时，可以将所述至少两个上行信道中传输时间单元较短的上行信道的传输时间单元确定为复用过程的时间单元；或者，将所述至少两个上行信道中目标类型的上行信道的传输时间单元确定为复用过程的时间单元。
举例来讲，对于MBS PUCCH和unicast PUCCH之间存在的时域重叠，可以基于其中一种上行信道对应的传输时间确定为复用过程的时间单元，比如选择最小的传输时间单元作为复用过程的时间单元，或者总是选择MBS PUCCH的传输时间单元作为复用过程的时间单元，或者总是选择unicast PUCCH的传输时间单元作为复用过程的时间单元。
S202、对于所述至少两个上行信道中跨越多个时间单元的目标上行信道，若未满足预设复用结束条件，则依次在与所述目标上行信道时域重叠的每一个时间单元中进行复用过程，直至满足预设复用结束条件，得到最终的复用过程的处理结果。
在本实施例中，在确定复用过程的时间单元后，所述至少两个上行信道中可能存 在跨越多个时间单元的目标上行信道，由于跨越多个时间单元的目标上行信道与未跨越时间单元的上行信道之间的传输时间单元不同，因此可在未满足预设复用结束条件时依次在与所述目标上行信道时域重叠的每一个时间单元中进行复用过程，直至满足预设复用结束条件。
其中，可选的，满足预设复用结束条件可以为当前不存在需要进行复用过程的上行信道，例如不存在PUCCH时域重叠，具体的，预设复用结束条件可以是时域重叠的上行信道被丢弃或与其他上行信道复用成功。
可选的，在依次在与所述目标上行信道时域重叠的每一个时间单元中进行复用过程时，具体可包括：
将当前复用过程的时间单元中所有PUCCH确定为Q集合，并根据时域重叠情况下的复用规则执行复用过程，得到当前复用过程的时间单元中时域不重叠的PUCCH。
在本实施例中，在依次进行复用过程中，对于当前复用过程的时间单元，可将其中所有PUCCH(包括相同优先级和不同优先级的PUCCH)确定为Q集合，然后根据时域重叠情况下的复用规则对Q集合中的PUCCH执行复用过程，例如将Q集合中至少一个上行信道承载的预设类型的UCI(Uplink Control Information，上行控制信息)转移到Q集合中的另一个上行信道上进行复用，其中UCI可包括HARQ-ACK、SR(Scheduling Request，调度请求)、CSI(Channel State Information，信道状态信息)中的至少一种；或者，也可将另外创建新的上行信道，将Q集合中至少一个上行信道承载的预设类型的UCI转移到新的上行信道进行复用。其中，预设类型的UCI为上行信道之间支持复用的UCI，例如支持复用的UCI可以为HARQ-ACK，而SR和CSI不支持复用，则在复用时仅仅将某一上行信道的HARQ-ACK承载到另一上行信道上进行复用，例如将HARQ-ACK由LP PUCCH转移到HP PUCCH上进行复用，而对于SR和CSI可进行丢弃。
S203、基于复用过程的处理结果进行上行信道传输。
在本实施例中，在完成复用过程得到最终的复用过程的处理结果后，可基于处理结果进行上行信道传输。具体的，若本实施例提供的上行复用传输方法执行主体为终端，则由终端向基站进行上行信道传输；若本实施例提供的上行复用传输方法执行主体为基站，则由基站接收终端传输的上行信道。
本实施例提供的上行复用传输方法，应用于终端或基站，通过在不同物理层优先级或不同类型的至少两个上行信道时域重叠的情况下，确定复用过程的时间单元；对于至少两个上行信道中跨越多个时间单元的目标上行信道，若未满足预设复用结束条件，则依次在与目标上行信道时域重叠的每一个时间单元中进行复用过程，直至满足预设复用结束条件，得到最终的复用过程的处理结果；基于复用过程的处理结果进行上行信道传输。本实施例在上行信道时域重叠的情况下通过依次在各复用过程的时间单元中进行复用过程，直至满足预设复用结束条件，可以将时域重叠的上行信道承载的上行控制信息复用到其他信道上，能够有效的进行上行复用传输，减少丢弃上行信道产生的影响。
在上述任一实施例的基础上，如图3所示，S202所述依次在与所述目标上行信道时域重叠的每一个时间单元中进行复用过程，直至满足预设复用结束条件，具体可包 括：
S301、对于跨越多个时间单元的低优先级PUCCH，在与所述低优先级PUCCH时域重叠的第一个时间单元中进行复用过程；
S302、若当前复用过程中确定所述低优先级PUCCH被丢弃或与其他上行信道复用成功，则停止后续与所述低优先级PUCCH时域重叠的其他时间单元中进行所述低优先级PUCCH的复用过程；
S303、否则，继续在下一个与所述低优先级PUCCH时域重叠的时间单元中进行所述低优先级PUCCH的复用过程；
重复上述过程，直至所述低优先级PUCCH被丢弃或与其他上行信道复用成功。
在本实施例中，在存在低优先级PUCCH跨越多个时间单元时，可在在该低优先级PUCCH未被丢弃且与未其他上行信道复用成功时，依次在与该低优先级PUCCH时域重叠的每一个时间单元中参与复用过程，直至该低优先级PUCCH被丢弃或与其他上行信道复用成功。
具体的，先在与该低优先级PUCCH时域重叠的第一个时间单元中进行复用过程，若第一个时间单元复用过程中确定该低优先级PUCCH被丢弃或与其他上行信道复用成功，则停止后续与所述低优先级PUCCH时域重叠的其他时间单元中进行所述低优先级PUCCH的复用过程；若该低优先级PUCCH未被丢弃且与未其他上行信道复用成功时，则在与该低优先级PUCCH时域重叠的第二个时间单元中进行复用过程，同样的，若第二个时间单元复用过程中确定该低优先级PUCCH被丢弃或与其他上行信道复用成功，则停止后续与所述低优先级PUCCH时域重叠的其他时间单元中进行所述低优先级PUCCH的复用过程；若该低优先级PUCCH未被丢弃且与未其他上行信道复用成功时，则在与该低优先级PUCCH时域重叠的第三个时间单元中进行复用过程，以此类推，直至该低优先级PUCCH被丢弃或与其他上行信道复用成功，或者直至最后一个与该低优先级PUCCH时域重叠的时间单元中进行复用过程完成。
需要说明的是，若当前复用过程的时间单元中不存在与所述目标上行信道时域重叠的上行信道，则继续在下一个与所述目标上行信道时域重叠的时间单元中进行复用过程。如上述实施例，若在第一个时间单元的复用过程中发现第一个时间单元中不存在与该低优先级PUCCH时域重叠的上行信道，则第一个时间单元中不需要进行复用过程，可继续进行第二个时间单元的复用过程，同样的，若第二个时间单元中也不存在与该低优先级PUCCH时域重叠的上行信道，则可继续进行第三个时间单元的复用过程，以此类推。
在上述实施例的基础上，在S202所述依次在与所述目标上行信道时域重叠的每一个时间单元中进行复用过程的过程中，还可包括：
若满足预设条件，则对所述Q集合中至少一个上行信道执行丢弃操作，所述预设条件包括：
在当前复用过程的时间单元中，经过复用过程得到的上行信道仍然跨多个时间单元；或者
在当前复用过程的时间单元中，经过复用过程得到的上行信道位于其它时间单元；或者
在当前复用过程的时间单元中，经过复用过程得到的上行信道的起始位置早于当前复用过程的时间单元的起始位置。
在本实施例中，在复用过程中通过对预设条件的判断，可以确定是否对上行信道执行丢弃操作，避免继续执行后续的复用过程。
在上述实施例的基础上，所述对所述Q集合中至少一个上行信道执行丢弃操作，具体可包括：
若所述Q集合中各上行信道的物理层优先级不同，则丢弃其中低优先级的上行信道；或者
若所述Q集合中各上行信道的物理层优先级相同，则基于各上行信道承载的UCI类型的预设优先级，丢弃其中承载低优先级UCI类型的上行信道。
在本实施例中，当确定需要对Q集合中至少一个上行信道执行丢弃操作时，若Q集合中各上行信道的物理层优先级不同，则丢弃其中低优先级的上行信道；若Q集合中各上行信道的物理层优先级相同，则可根据各上行信道承载的UCI类型来确定丢弃哪一个或哪些上行信道，其中可以预先设定UCI类型的预设优先级，可选的，UCI类型的预设优先级顺序为：HARQ-ACK>SR>CSI。若需要丢弃两个LP PUCCH中的一个上行信道，其中第一LP PUCCH承载的UCI类型为HARQ-ACK，第二LP PUCCH承载的UCI类型为CSI，由于HARQ-ACK优先级高于CSI，因此丢弃第二LP PUCCH。
上述实施例中描述了存在不同物理层优先级的上行信道时域重叠的情况，对于存在不同类型的至少两个上行信道时域重叠的情况，其实现方式与之类似。例如，在确定复用过程的时间单元后，若第一类型的PUCCH跨越多个时间单元，若未满足预设复用结束条件，依次在与该PUCCH时域重叠的每一个时间单元中进行复用过程，直至满足预设复用结束条件，得到最终的复用过程的处理结果，具体的，可在与该PUCCH时域重叠的第一个时间单元中进行复用过程，若当前复用过程中确定该PUCCH被丢弃或与其他上行信道复用成功，则停止后续与该PUCCH时域重叠的其他时间单元中进行该PUCCH的复用过程；否则，继续在下一个与该PUCCH时域重叠的时间单元中进行该PUCCH的复用过程，重复上述过程，直至该PUCCH被丢弃或与其他上行信道复用成功。最后基于复用过程的处理结果进行上行信道传输。其中，丢弃操作的预设条件同上述实施例，丢弃操作时可按照物理层优先级或者UCI类型优先级进行丢弃，当然也可按照其他顺序或其他预设规则进行丢弃，此处不做限制。
在上述任一实施例的基础上，所述上行复用传输方法还包括：
在所述复用过程的处理结果中的PUCCH和物理上行共享信道PUSCH存在时域重叠的情况下，若确定终端支持PUCCH和PUSCH的并行传输，则同时传输该PUCCH和该PUSCH；
若确定终端不支持PUCCH和PUSCH的并行传输，则对该PUCCH和该PUSCH进行复用传输、或丢弃其中一个上行信道。
在本实施例中，上述实施例中可能同时存在PUCCH和PUSCH的时域重叠情况，例如若存在多个PUCCH时域重叠，同时又和PUSCH重叠，则可先执行S201-S203的过程得到时域不重叠的PUCCH，若此时时域不重叠的PUCCH与PUSCH重叠，则可先确定终端是否支持PUCCH和PUSCH的并行传输，若终端支持PUCCH和PUSCH 的并行传输，则同时传输该PUCCH和该PUSCH；若终端不支持PUCCH和PUSCH的并行传输，则对该PUCCH和该PUSCH进行复用传输、或丢弃其中一个上行信道，其中复用传输可以将PUCCH承载的UCI转移到PUSCH上进行复用，当然也可将PUSCH承载的UCI转移到PUCCH上进行复用。需要说明的是，终端是否支持PUCCH和PUSCH的并行传输，可由基站进行控制，或者由终端用户进行设置，或者通过其他途径进行控制。
下面将结合具体示例，对上述各实施例中的上行复用传输方法进行详细说明。其中所描述的各示例仅仅是本公开提供一种上行复用传输方法的一部分实施例，而不是全部的实施例，基于本公开中的示例，本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例，都属于本公开保护的范围。
示例1：
在主载波(Master(primary)Cell Group，MCG)上，高优先级HARQ-ACK被配置基于7个符号长度的Sub-slot传输，低优先级HARQ-ACK被配置了基于Slot传输，则将高优先级HARQ-ACK的传输时间单元Sub-slot作为复用过程的时间单元。
情况1：如图4所示，一个低优先级的LP PUCCH和两个高优先级Sub-slot在时域上重叠，并且在每个高优先级Sub-slot内分别和一个高优先级HP PUCCH在时域上重叠。在图4中的第一个复用过程的时间单元中，定义Q集合包含HP PUCCH-1和LP PUCCH，基于时域重叠情况下的复用规则，终端可能会丢弃LP PUCCH或者将LP PUCCH承载的UCI信息转移到HP PUCCH-1上进行复用传输，则LP PUCCH不再参与第二个Sub-slot中的复用过程，第一个复用过程的时间单元中经过复用得到一个HP PUCCH-1。在第二个复用过程的时间单元中，只有一个HP PUCCH-2，没有时域上重叠的信道，因此也得到一个HP PUCCH-2。最终，终端在第一个复用过程的时间单元中传输一个HP PUCCH-1(可以包含转移的LP UCI)，LP PUCCH被丢弃，在第二个复用过程的时间单元传输一个HP PUCCH-2。
情况2：如图5所示，一个低优先级的LP PUCCH和两个高优先级Sub-slot在时域上重叠，但是在第一个高优先级Sub-slot内不和高优先级PUCCH重叠，在第二个高优先级Sub-slot内和一个高优先级PUCCH在时域上重叠。在图5中的第一个复用过程的时间单元中，由于不存在时域重叠，不需要执行复用过程，则LP PUCCH没有被丢弃，也没有与其他上行信道复用，可以继续参与后续的复用过程。在第二个复用过程的时间单元中，定义Q集合包含HP PUCCH-2和LP PUCCH，基于时域重叠情况下的复用规则，终端可能会丢弃LP PUCCH或者将LP PUCCH承载的UCI信息转移到HP PUCCH-2上进行复用传输，最终，终端在第一个复用过程的时间单元中传输一个HP PUCCH-1，在第二个复用过程的时间单元传输一个HP PUCCH-2(可以包含转移的LP UCI)，LP PUCCH被丢弃。
情况3：如图6所示，一个低优先级的LP PUCCH-2和两个高优先级Sub-slot在时域上重叠，但是在第一个高优先级Sub-slot内和一个低优先级的LP PUCCH-1重叠，在第二个高优先级Sub-slot内和一个高优先级HP PUCCH在时域上重叠。在图6中的第一个复用过程的时间单元中，定义Q集合包含LP PUCCH-1和LP PUCCH-2，基于时域重叠情况下的复用规则，终端可能会将LP PUCCH-1承载的UCI信息转移到LP  PUCCH-2上进行复用传输，假设LP PUCCH-1承载了LP HARQ-ACK，LP PUCCH-2承载了LP CSI，则复用后LP PUCCH-2资源上承载了LP HARQ-ACK和LP CSI。在第二个复用过程的时间单元中，定义Q集合包含HP PUCCH和LP PUCCH-2，基于时域重叠情况下的复用规则，终端可能会将LP PUCCH-2承载的UCI信息转移到HP PUCCH上进行复用传输，进一步可选的，假如仅支持LP HARQ-ACK和HP HARQ-ACK复用，不支持LP CSI和HP HARQ-ACK复用，则将LP PUCCH-2承载的LP HARQ-ACK转移到HP PUCCH传输，LP CSI无法转移到HP PUCCH传输，丢弃LP CSI。最终，终端在第一个复用过程的时间单元中不传输任何信道，在第二个复用过程的时间单元传输一个HP PUCCH-2(可以包含转移的LP HARQ-ACK)，LP PUCCH-1和LP PUCCH-2均被丢弃。
情况4：如图7所示，一个低优先级的LP PUCCH-1和两个高优先级Sub-slot在时域上重叠，但是在第一个高优先级Sub-slot内和一个高优先级的HP PUCCH-2重叠，所述高优先级的HP PUCCH-2和一个高优先级HP PUCCH-1重叠，在第二个高优先级Sub-slot内和一个低优先级LP PUCCH-2在时域上重叠。在图7中的第一个复用过程的时间单元中，定义Q集合包含HP PUCCH-1、HP PUCCH-2和LP PUCCH-1，基于时域重叠情况下的复用规则，终端可能会将HP PUCCH-2承载的UCI信息转移到HP PUCCH-1上进行复用传输，则复用后得到HP PUCCH-1和LP PUCCH-1两个信道，LP PUCCH-1可以继续参与后续的复用过程。在第二个复用过程的时间单元中，定义Q集合包含LP PUCCH-1和LP PUCCH-2，基于时域重叠情况下的复用规则，终端可能会将LP PUCCH-1承载的UCI信息转移到LP PUCCH-2上进行复用传输，则复用后得到LP PUCCH-2信道。最终，终端在第一个复用过程的时间单元中传输HP PUCCH-1(包含转移的HP PUCCH-2的UCI信息)，在第二个复用过程的时间单元传输一个LP PUCCH-2(包含转移的LP PUCCH-1的UCI信息)，HP PUCCH-2和LP PUCCH-1均被丢弃。
示例2：
在主载波上，高优先级HARQ-ACK被配置基于7个符号长度的Sub-slot传输，低优先级HARQ-ACK被配置了基于Slot传输，则将高优先级HARQ-ACK的Sub-slot作为复用过程的时间单元。
情况1：如图8所示，在第一个高优先级Sub-slot内只有一个HP PUCCH，在第二个高优先级Sub-slot内有一个LP PUCCH-1和一个LP PUCCH-2重叠。在图8中的第一个复用过程的时间单元中，由于不存在重叠所以不需要执行复用过程。在第二个复用过程的时间单元中，定义Q集合包含LP PUCCH-1和LP PUCCH-2，基于时域重叠情况下的复用规则，终端可能会选择在一个新的LP PUCCH-3进行复用传输，如图8所示，由于LP PUCCH-3位于前一个复用过程的时间单元，满足上述实施例中提及的预设条件，则不支持LP PUCCH-1和LP PUCCH-2进行复用，进一步可选的，假设LP PUCCH-1承载HARQ-ACK，LP PUCCH-2承载CSI/SR，则丢弃LP PUCCH-2和它所承载的UCI，在第二个复用过程的时间单元中仅传输LP PUCCH-1。最终，终端在第一个复用过程的时间单元中传输一个HP PUCCH，在第二个复用过程的时间单元传输一个LP PUCCH-1(不包含转移的LP UCI)，LP PUCCH-2被丢弃。
类似的，在本示例情况1中，如果在第二个复用过程的时间单元中，如图9所示，若确定复用后的LP PUCCH-3的起始位置早于当前复用过程的时间单元，或者确定复用后的LP PUCCH-3的资源跨出了当前复用过程的时间单元，都可以不支持LP PUCCH-2的传输，仅传输LP PUCCH-1。
情况2：如图10所示，在第一个高优先级Sub-slot内只有一个HP PUCCH，在第二个高优先级Sub-slot内有一个LP PUCCH-1和一个LP PUCCH-2重叠。在图10中的第一个复用过程的时间单元中，由于不存在重叠所以不需要执行复用过程。在第二个复用过程的时间单元中，定义Q集合包含LP PUCCH-1和LP PUCCH-2，基于时域重叠情况下的复用规则，终端可能会选择在一个新的LP PUCCH-3进行复用传输，如图10所示，由于LP PUCCH-3位于当前复用过程的时间单元，则支持LP PUCCH-1和LP PUCCH-2进行复用，假设LP PUCCH-1承载HARQ-ACK，LP PUCCH-2承载CSI/SR，则将HARQ-ACK和CSI/SR都转移到LP PUCCH-3上进行传输。最终，终端在第一个复用过程的时间单元中传输一个HP PUCCH，在第二个复用过程的时间单元传输一个LP PUCCH-3(包含转移的LP HARQ-ACK和CSI/SR)。
情况3：如图11所示，在第一个高优先级Sub-slot内有一个LP PUCCH-1和一个LP PUCCH-2重叠，在第二个高优先级Sub-slot内只有一个HP PUCCH。在图11中的第一个复用过程的时间单元中，定义Q集合包含LP PUCCH-1和LP PUCCH-2，基于时域重叠情况下的复用规则，终端可能会通过一个新的LP PUCCH-3进行复用传输，如图12-图14所示。
情况3-1：如图12所示，LP PUCCH-3位于当前复用过程的时间单元，则支持LP PUCCH-1和LP PUCCH-2进行复用。最终，终端在第一个复用过程的时间单元中传输一个LP PUCCH-3(包含LP PUCCH-1和LP PUCCH-2转移的LP UCI)，在第二个复用过程的时间单元传输一个HP PUCCH。
情况3-2：如图13或图14所示，LP PUCCH-3跨多个复用过程的时间单元或者位于其它的复用过程的时间单元中，则可采用以下任意一种方式。
方式一：不支持LP PUCCH-1和LP PUCCH-2进行复用，假设LP PUCCH-1承载HARQ-ACK，LP PUCCH-2承载CSI/SR，则根据UCI类型的预设优先级丢弃LP PUCCH-2和它所承载的UCI，在第一个复用过程的时间单元中仅传输LP PUCCH-1。最终，终端在第一个复用过程的时间单元传输一个LP PUCCH-1(不包含转移的LP UCI)，LP PUCCH-2被丢弃，在第二个复用过程的时间单元中传输一个HP PUCCH。
方式二：支持LP PUCCH-1和LP PUCCH-2进行复用，假设LP PUCCH-1承载HARQ-ACK，LP PUCCH-2承载CSI/SR，则在第一个复用过程的时间单元中通过复用过程得到新的LP PUCCH-3。在第二个复用过程的时间单元中，定义Q集合包含LP PUCCH-3和HP PUCCH，基于时域重叠情况下的复用规则，终端可能会通过HP PUCCH进行复用传输。最终，终端在第一个复用过程的时间单元不传输任何信道，在第二个复用过程的时间单元中传输一个HP PUCCH(包含转移的LP HARQ-ACK)。
通过上述各实施例提供的上行复用传输方法，在上行信道时域重叠的情况下能够有效的进行上行复用传输，减少丢弃上行信道产生的影响。
