  • PUCCH and PUCCH overlap, at least one PUCCH is repeatedly transmitted (that is, occupying multiple time slots to repeatedly transmit UCI in each time slot), only for the overlapping repetition (repetition), according to the transmission high priority, Discard low-priority processing without affecting repetitions that do not overlap. If the PUCCH overlaps with the PUSCH of repeated transmission, when the PUSCH adopts the repeated transmission based on time slots (R15 repeated transmission, or R16 repetition type A), the UCI carried on the PUCCH is transferred to one or more PUSCH time slots that overlap with the PUCCH for transmission.

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。
本公开实施例提供了一种信道复用方法、装置及通信设备，用以提高优先级上行信道的传输灵活性，保证传输时延满足需求。
其中，方法和装置是基于同一申请构思的，由于方法和装置、通信设备解决问题的原理相似，因此装置、通信设备和方法的实施可以相互参见，重复之处不再赘述。
参见图1，图1是本公开实施例可应用的网络结构示意图，如图1所示，包括终端11和基站12，其中，终端11可以是用户终端(User Equipment，UE)或者其他终端设备，例如：手机、平板电脑(Tablet Personal Computer)、膝上型电脑(Laptop Computer)、个人数字助理(personal digital assistant，简称PDA)、移动上网装置(Mobile Internet Device，MID)或可穿戴式设备(Wearable Device)等终端侧设备，需要说明的是，在本公开实施例中并不限定终端的具体类型。基站12，例如：宏站、LTE eNB、5G NR节点B(Node B，NB)等；网络侧设备也可以是小站，如低功率节点(LPN：low power node)、pico、femto等小站，或者网络侧设备可以接入点(AP，access point)；基站也可以是中央单元(CU，central unit)与其管理是和控制的多个传输接收点(TRP，Transmission Reception Point)共同组成的网络节点。需要说明的是，在本公开实施例中并不限定网络侧设备的具体类型。
首先，针对具有不同优先级的上行信道复用传输做以下说明：
1、不同物理层优先级的信道传输：
一个UE可以支持不同的业务类型，如增强移动宽带(enhanced Mobile Broadband，eMBB)业务和低时延高可靠通信(Ultra-Reliable and Low Latency Communication，URLLC)业务等。不同的业务类型对可靠性和传输时延的需求不同。URLLC业务流可能是零散的不定时发生的，因此针对不同的业务独立预留不同的系统资源，在系统资源上的开销比较大，可能很多时候为URLLC预留的资源都是没有被使用的。为了提高系统资源利用率，可以支持不同业务在相同资源上复用传输。可能发生一个较早被调度的数据传输被另一个较晚被调度的数据传输所打断或取消的情况。举例来说，一个UE被调度了eMBB业务在资源1上传输之后，由于URLLC业务到达，而为了满足URLLC业务的时延需求，需要尽快调度，可能会占用已经分配给eMBB业务的资源1中的全部或部分资源(包括时域资源和/或频域资源)进行URLLC传输，例如可能是同一个载波上调度给eMBB的时域资源(符号集合)中的全部或部分符号上被调度了URLLC传输，不论频域资源是否重叠，因为在同一个时刻上同一个载波上不能同时传输两个上行信道，则eMBB业务会被URLLC业务所打断或取消。
为了避免业务之间的相互影响，可以对不同的业务定义不同的优先级，从而在出现资源冲突的时候，选择高优先级的信道传输，丢弃低优先级的信道。因此，为了更好的支持具有不同需求的不同业务的传输，相关技术中引入了物理层优先级，并且规定，当具有不同物理层优先级的信道发生冲突时，即多个PUCCH在同一个载波上在时域上存在重叠，或PUCCH和物理上行共享信道(Physical Uplink Shared Channel，PUSCH)在同一个载波上在时域上存在重叠时，丢弃低优先级的信道，只传输高优先级的信道。
PUCCH、PUSCH的物理层优先级可以通过默认方式、下行控制信息(Downlink Control Information，DCI)动态指示或者无线资源控制(Radio Resource Control，RRC)半静态配置的方式获得。例如，PUCCH在承载调度请求(Scheduling Request，SR)时，其优先级是通过其承载的SR对应的优先级确定的，而每个SR配置对应的优先级是高层信令配置的；PUCCH在承载半持续调度(Semi-Persistent Scheduling，SPS)物理下行共享信道(Physical Downlink Shared Channel，PDSCH)的混合自动重传请求确认(Hybrid Automatic Repeat request-ACKnowledgment，HARQ-ACK)或承载指示SPS资源释放的物理下行控制信道(Physical Downlink Control Channel，PDCCH)(即SPS PDSCH release)的HARQ-ACK时，其优先级是通过高层信令为SPS PDSCH配置的HARQ-ACK码本编号来确定的，对应编号为0的HARQ-ACK码本为低优先级，对应编号为1的HARQ-ACK码本为高优先级；PUCCH在承载信道状态信息(Channel State Information，CSI)(包括周期CSI和半持续信道状态信息(semi-persistent CSI，SP-CSI))时，其优先级默认为低优先级。当DCI中包含优先级指示域时，可以通过PUCCH、PUSCH对应的DCI(或PDCCH，本公开中PDCCH和DCI可以认为等价，DCI是PDCCH传输使用的具体格式，则具有对应的DCI等价于具有对应的PDCCH)中的优先级指示域获得优先级，例如，PDCCH所使用的DCI中包含优先级指示域，则：PDCCH调度一个PDSCH时，可以通过优先级指示域指示承载这个PDSCH的HARQ-ACK的PUCCH的优先级；PDCCH调度一个PUSCH时，可以通过优先级指示域指示被调度的PUSCH的优先级，其中，PUSCH包括仅承载传输块(Transport Block，TB)的PUSCH或仅承载非周期信道状态信息(Aperiodic CSI，A-CSI)的PUSCH 或同时承载TB和A-CSI的PUSCH；对于承载SP-CSI的PUSCH，其优先级可以通过激活承载SP-CSI的PUSCH的DCI中的优先级指示域获得。如果DCI中不包含优先级指示域，或高层信令没有配置优先级，则默认为低优先级。
2、5G NR中的UCI传输
UCI包含HARQ-ACK，CSI，SR等信息。UCI在PUCCH上传输。其中，HARQ-ACK是肯定确认(ACKnowledgment，ACK)和否定确认(Non-ACKnowledgment，NACK)的统称，用于针对PDSCH或指示SPS资源释放的PDCCH(又称SPS PDSCH release)进行反馈，告知基站PDSCH或指示SPS PDSCH释放的PDCCH是否正确接收；CSI用于反馈下行信道质量，从而帮助基站更好的进行下行调度，例如根据CSI进行调制编码等级(Modulation and Coding Scheme，MCS)选择、配置适当的资源块(Resource Block，RB)资源等；SR用于当终端有上行业务需要传输时，向基站请求携带上行业务的PUSCH的传输资源。
3、相同优先级的PUCCH与PUCCH/PUSCH重叠
NR中不支持PUCCH与PUSCH在同一时刻并行传输，不管是同一个载波还是不同载波上。当PUCCH和PUSCH(不做特殊说明，一般PUCCH和PUSCH指不使用重复传输的PUCCH和PUSCH)在时域资源上存在重叠时，在满足预定的时间条件(timeline)的情况下，可以将UCI(一般是HARQ-ACK和CSI)从PUCCH上转移到一个PUSCH上传输，如果存在SR，则SR不在PUSCH上传输，SR被丢弃。如果存在多个PUSCH都与PUCCH重叠，则按照预定的规则选择一个PUSCH，其中优先选择承载A-CSI的PUSCH，如果同时存在具有PDCCH调度的PUSCH(动态授权(Dynamic grant，DG)PUSCH)和没有PDCCH调度的PUSCH(配置授权(Configured grant，CG)PUSCH，SP-CSI PUSCH等)，优先选择DG PUSCH，按照上述规则选择之后，如果多个载波上都有PUSCH，优先选择载波编号低的载波上的PUSCH，如果选择的载波上存在多个时域上不重叠的PUSCH与PUCCH重叠，选择最早的PUSCH。
其次，关于相关的上行信道复用传输技术中存在的技术问题做以下说明：
目前的技术中，为了保证具有不同优先级的上行信道进行复用传输的时候，比较早起始的信道可以在准备之前获得是否存在比较晚起点的信道与之 重叠，并从而根据复用规则做出复用传输决策，要求复用传输的信道之间都需要满足复用的时间条件。但对于高优先级的信道，通常承载对时延比较敏感的重要业务的UCI或数据，如果想要占用已经调度传输的低优先级的信道所在的时域资源进行传输，如果总是满足复用的时间条件，对高优先级信道的调度限制非常大，可能会导致其时延增大较多。目前，在希望支持具有不同优先级的信道进行复用传输的场景中，如何保证高优先级的信道传输的低时延特性，保留高优先级信道足够的调度灵活性还没有明确方法。
针对上述问题，本公开提供了以下技术方案。
请参阅图2，图2为本公开实施例提供的一种信道复用方法的流程示意图，该方法应用于通信设备，包括以下步骤：
S101：当具有不同优先级的上行信道在时域上存在重叠时，确定是否允许所述上行信道之间进行复用传输；
其中，具有不同优先级的上行信道在时域上存在重叠，也即具有不同优先级的上行信道冲突。
S102：在确定允许所述上行信道之间进行复用传输时，确定所述上行信道需要满足预定的时间条件；
S103：在确定不允许所述上行信道之间进行复用传输时，确定所述上行信道不需要满足所述时间条件。
其中，复用传输是指不同优先级的上行信道上承载的信息在同一个上行信道上同时传输。如果确定不允许具有不同优先级的上行信道之间进行复用传输，则丢弃低优先级的上行信道。
本公开实施例提供了一种不同优先级的上行信道冲突时的复用传输方法，根据是否支持不同优先级的UCI复用传输的判断结果，确定是否需要满足预定的时间条件，在决策不支持或不进行不同优先级的UCI复用传输时，不需要对重叠信道进行时间条件判断，从而不限制高优先级的上行信道的调度，提高优先级上行信道的传输灵活性，保证传输时延满足需求。
可选的，所述确定是否允许所述上行信道之间进行复用传输，包括：
根据配置信令，确定是否允许所述上行信道之间进行复用传输；其中，所述配置信令包括以下至少之一：
与所述上行信道对应的下行控制信道中的下行控制信息，所述下行控制信息携带指示信息；其中，这里的上行信道具体可以是具有不同优先级的、在时域上存在重叠的上行信道中的一个或多个上行信道；
高层信令。
也就是说，所述根据配置信令，确定是否允许所述上行信道之间进行复用传输，具体包括：
根据与所述上行信道对应的下行控制信道中的指示信息，确定是否允许所述上行信道之间进行复用传输；
或者，
根据高层信令，确定是否允许所述上行信道之间进行复用传输。例如，可以半静态的配置是否支持(即允许)具有不同优先级的上行信道进行复用传输。
可选的，所述指示信息指示是否允许(或者说存在)复用传输；或者，
所述指示信息指示用于确定与所述上行信道承载的高优先级的上行控制信息在同一个上行信道上同时传输的低优先级的上行控制信息的第一参考比特数的信息，所述第一参考比特数用于确定是否允许所述上行信道之间进行复用传输。
进一步可选的，当根据所述指示信息确定所述第一参考比特数为0时，确定不允许所述上行信道之间进行复用传输，当根据所述指示信息确定所述第一参考比特数大于0时，确定允许所述上行信道之间进行复用传输。
关于所述指示信息指示是否允许复用传输，具体的，指示状态可以是允许或不允许中的一个，或者指示状态可以是存在或不存在中的一个，或者指示状态可以是支持或不支持中的一个。例如，调度PDSCH的PDCCH或指示SPS PDSCH激活的PDCCH或需要进行HARQ-ACK反馈的PDCCH(例如指示SPS PDSCH资源释放、指示辅小区(Secondary Cell，SCell)休眠(Dormancy)等的PDCCH)中存在指示域，指示是否允许具有与PDCCH对应的HARQ-ACK(即PDCCH所调度或激活的PDSCH的HARQ-ACK或PDCCH本身的HARQ-ACK)不同优先级的UCI，与所述HARQ-ACK在同一个上行信道(PUCCH或PUSCH)上同时传输。又例如，调度PUSCH的PDCCH或 指示CG PUSCH激活的PDCCH中存在指示域，指示在PUSCH上是否允许传输与PUSCH具有不同优先级的UCI。
关于所述指示信息指示用于确定与所述上行信道承载的高优先级的上行控制信息在同一个上行信道上同时传输的低优先级的上行控制信息的第一参考比特数的信息：例如，调度PDSCH的PDCCH或指示SPS PDSCH激活的PDCCH或需要进行HARQ-ACK反馈的PDCCH(例如指示SPS PDSCH资源释放、指示辅小区休眠(Secondary Cell Dormancy，SCell Dormancy)等的PDCCH)中存在指示域，指示用于确定与PDCCH对应的HARQ-ACK在同一个信道上同时传输的、与所述HARQ-ACK具有不同优先级的UCI的比特数的指示信息，当根据指示信息确定的第一参考比特数为0时，确定结果为不允许，当根据指示信息确定的第一参考比特数大于0时，确定结果为允许。又例如，调度PUSCH的PDCCH或指示CG PUSCH激活的PDCCH中存在指示域，指示用于确定在PUSCH上传输与PUSCH具有不同优先级的UCI的比特数或资源(可以根据指示的贝塔偏移(beta-offset)来确定)的指示信息，当根据指示信息确定的第一参考比特数或资源为0时，确定结果为不允许，当根据指示信息确定的第一参考比特数或资源大于0时，确定结果为允许。
如果DCI(即PDCCH)中存在指示域指示是否存在或允许在低优先级(Low priority，LP)与高优先级(High priority，HP)复用(即低优先级上行信道与高优先级上行信道复用传输)，则指示为存在时，复用的上行信道需要总是满足复用timeline，指示为不存在时，复用的上行信道不用满足复用timeline。
可选的，所述确定是否允许所述上行信道之间进行复用传输，包括：
根据所述上行信道中承载的高优先级的上行控制信息的比特数或比特数所对应的比特区间，确定与所述高优先级的上行控制信息在同一个上行信道上同时传输的低优先级的上行控制信息的第二参考比特数；其中，每一个高优先级的上行控制信息的比特数或比特数所对应的比特区间，分别对应一个低优先级的上行控制信息的第二参考比特数；
根据所述第二参考比特数，确定是否允许所述上行信道之间进行复用传 输。
例如，当所述第二参考比特数为0时，确定不允许所述上行信道之间进行复用传输；当所述第二参考比特数大于0时，确定允许所述上行信道之间进行复用传输。
其中，高优先级的上行控制信息的比特数所对应的比特区间是指高优先级的上行控制信息的比特数所属的取值范围。
具体的，可以预先定义或配置高优先级的上行控制信息的比特数或比特数所对应的比特区间与低优先级的上行控制信息的第二参考比特数之间的对应关系，然后如果具有不同优先级的上行信道在时域上存在重叠，那么根据这些在时域上存在重叠的上行信道中优先级高的上行信道对应的上行控制信息的比特数以及所述对应关系，确定能够与高优先级的上行信道对应的上行控制信息在同一个信道上同时传输的低优先级的上行控制信息的第二参考比特数。
在根据高优先级(HP)的比特数或比特数所对应的比特区间(即高优先级的上行控制信息的比特数或比特数所对应的比特区间)，确定对应的低优先级(LP)的第二参考比特数(即低优先级的上行控制信息的第二参考比特数)时，如果确定的第二参考比特数大于0或存在LP，则总是需要满足复用timeline，如果确定的第二参考比特数为0或对应无LP，则不用满足复用timeline。
可选的，所述通信设备为基站；所述方法还包括：
若确定所述上行信道不需要满足所述时间条件，在调度或配置所述上行信道时，不需要保证所述上行信道满足所述时间条件。
本公开实施例中，如果确定不允许具有不同优先级的上行信道之间进行复用传输，则确定在时域上存在重叠的、具有不同优先级的上行信道不需要满足上述时间条件，那么对于基站侧来说，在调度或配置上行信道时，对于在时域上存在重叠的、具有不同优先级的上行信道不需要保证满足上述时间条件。
可选的，所述通信设备为终端；所述方法还包括：
若确定所述上行信道不需要满足所述时间条件，在进行复用传输之前， 不需要检查所述上行信道是否满足所述时间条件。
本公开实施例中，如果确定不允许具有不同优先级的上行信道之间进行复用传输，则确定在时域上存在重叠的、具有不同优先级的上行信道不需要满足上述时间条件，那么对于终端侧来说，不需要检查在时域上存在重叠的、具有不同优先级的上行信道是否满足上述时间条件。
当然，若确定所述上行信道不需要满足所述时间条件，终端也可以在进行复用传输之前检查所述上行信道是否满足所述时间条件，但即使检查的结果是不满足，也不会认为是错误调度，而是不进行复用传输，传输重叠的信道中的高优先级的上行信道，不传输(即丢弃)低优先级的上行信道。
可选的，所述通信设备为基站；所述方法还包括：
若确定所述上行信道需要满足所述时间条件，在调度或配置所述上行信道时，需要保证所述上行信道满足所述时间条件。
本公开实施例中，如果确定允许具有不同优先级的上行信道之间进行复用传输，则确定在时域上存在重叠的、具有不同优先级的上行信道需要满足上述时间条件，那么对于基站侧来说，在调度或配置上行信道时，对于在时域上存在重叠的、具有不同优先级的上行信道需要保证满足上述时间条件。
可选的，所述通信设备为终端；所述方法还包括：
若确定所述上行信道需要满足所述时间条件，在进行复用传输之前，检查所述上行信道是否满足所述时间条件。
本公开实施例中，如果确定允许具有不同优先级的上行信道之间进行复用传输，则确定在时域上存在重叠的、具有不同优先级的上行信道需要满足上述时间条件，那么对于终端侧来说，在进行复用传输之前，需要检查在时域上存在重叠的、具有不同优先级的上行信道是否满足上述时间条件。如果检查结果为不满足，则认为是错误调度，则没有规范的终端行为，终端可以对所有重叠的上行信道都不传输，或者随意选择传输其中一个上行信道等；如果检查结果为满足，才能进行不同优先级的上行信道的复用传输。
本公开实施例中，所述时间条件，可以是相关技术中定义的针对多个PUCCH在时域上重叠、或PUCCH与PUSCH在时域上重叠时需要满足的时间条件。其中，时间条件(timeline)的定义为：如果PUCCH或PUSCH具 有对应的PDCCH时，例如PUCCH承载的HARQ-ACK为具有PDCCH调度的PDSCH的HARQ-ACK或为指示下行SPS资源释放的PDCCH的HARQ-ACK，则该调度PDSCH的PDCCH或指示下行SPS资源释放的PDCCH为PUCCH对应的PDCCH，或者也可以称为调度PUCCH的PDCCH，调度PUSCH的PDCCH则为PUSCH对应的PDCCH，将重叠的PUCCH和PUSCH中的起始时间最早的信道的第一个符号作为目标符号，如果存在多个起始时刻相同的信道，则随便选一个信道，将其第一个符号作目标符号，目标符号需要满足如下timeline才能进行复用传输，否则认为是错误调度：
Timeline1：目标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 release的最后一个符号之后的T1mux时间之后的第一个符号(包括循环前缀(Cyclic Prefix，CP)在内的)，即目标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T1mux时间。T1mux与PDSCH的处理时延有关，可以根据预定的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：目标符号不早于调度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T2mux时间之后的第一个符号(包括CP在内的)，即目标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T2mux时间。T2mux与PUSCH的处理时延有关，可以根据预定的公式和相关的参数计算得到。该timeline的目的是保证当UCI需要转移到PUSCH上传输时，能够在PUCCH开始准备之前获得调度PUSCH的PDCCH，从而确定不需要在PUCCH上准备UCI传输，并且能够在PUSCH传输之前完成包括UCI在内的传输准备，即完成UCI的获取和复用处理，完成TB的准备(如编码、调制，加扰等操作)；如果是多个PUCCH之间的复用，这个T2mux是用来模拟CSI和SR与HARQ-ACK复用的准备时间的。
如果PUCCH承载的HARQ-ACK没有对应的PDCCH(即HARQ-ACK为SPS PDSCH的HARQ-ACK)，此时没有调度PDSCH的PDCCH，如果没 有PUSCH或PUSCH也没有对应的PDCCH，则仅需要check T1mux不需要check T2mux。如果PUCCH上承载的是CSI和/或SR，因为没有对应的PDSCH，则不需要check T1mux，进一步如果没有PUSCH或PUSCH没有对应的PDCCH，则也不需要check T2mux。
如果PUCCH和PUCCH重叠时，至少一个PUCCH是重复传输的(即占用多个时隙在每个时隙中重复性的传输UCI)，则仅针对重叠的重复(repetition)，按照传输高优先级，丢弃低优先级处理，不影响不存在重叠的repetition。如果PUCCH和重复传输的PUSCH重叠，当PUSCH采用基于时隙的重复传输时(R15重复传输，或R16repetition type A)，PUCCH承载的UCI转移到和PUCCH重叠的一个或者多个PUSCH时隙中进行传输；当PUSCH采用R16repetition type B时，PUCCH承载的UCI转移到和PUCCH重叠的最早的一个包含大于1个符号的actual repetition PUSCH中传输(actual repetition即根据不可用符号、DL符号、时隙边界等进行分段之后得到的repetition PUSCH)；上述与PUCCH重叠的一个或多个repetition的PUSCH都需要满足复用timeline。如果多时隙PUCCH与单时隙或多时隙PUSCH重叠，则丢弃与PUCCH重叠的PUSCH，保证PUCCH的重复传输不被打断。
另外，所述预定的时间条件也可以是相关技术中针对不同优先级的PUCCH和/或PUSCH之间在时域存在重叠时的复用传输新定义的时间条件。例如，基于高优先级的上行信道的起点判断所有DCI和PDSCH是否满足T1mux、T2mux等。
下面举例说明上述信道复用方法。
请参阅图3所示的不同优先级的PUCCH之间的重叠情况，其中LP表示低优先级，HP表示高优先级，AN为HARQ-ACK的简称。
其中一种信道复用的实现方式为：调度对应HP AN的PDSCH的下行调度授权(DL grant，即PDCCH)中可以存在指示域，指示是否支持HP AN和LP AN在同一个信道复用传输，当接收到对应HP AN的DL grant时，通过解析这个DL grant，UE可以获得其中的指示域，根据这个指示域可以确定是否支持HP AN和LP AN在同一个信道复用传输。
具体的，如果指示支持(比如指示状态可以是支持，也可以是指示用于 确定与HP AN复用的LP AN的比特数，确定比特数是大于0的，则证明存在并且允许LP AN与HP AN复用传输)，则UE在对重叠的HP AN和LP AN按照预定义的复用传输规则，在同一个上行信道上同时传输之前，需要判断：1)在重叠的承载HP AN的PUCCH和承载LP AN的PUCCH之中，起始符号最早的PUCCH(即图3中的LP AN PUCCH)的第一个符号，与HP AN和LP AN对应的DL grant之间，是否均满足时间间隔不短于复用传输所需的T2mux(T2mux按照相关技术中的定义可以根据相关公式和参数计算得到)；2)在重叠的承载HP AN的PUCCH和承载LP AN的PUCCH之中，起始符号最早的PUCCH的第一个符号，与HP AN和LP AN对应的PDSCH之间，是否均满足时间间隔不短于复用传输所需的T1mux(T1mux按照相关技术中的定义可以根据相关公式和参数计算得到)；当上述两个时间条件都满足的时候，确定可以进行复用传输，根据复用传输规则，确定一个PUCCH资源，用于同时传输HP AN和LP AN，如图4所示。
如果指示不支持(比如指示状态可以是不支持，也可以是指示用于确定与HP AN复用的LP AN的比特数，确定比特数是0，则证明不存在或不允许LP AN与HP AN复用传输)，则因为并不需要将HP AN和LP AN放在同一个上行信道上传输，且LP AN PUCCH与HP AN PUCCH重叠的部分是需要丢弃，终端在根据HP AN对应的DL grant确定并不支持HP AN和LP AN复用传输时，不再需要对DL grant和PDSCH与PUCCH之间进行是否满足T1mux和T2mux的判断，可以直接按照HP AN对应的PUCCH资源进行HP AN传输，并对于与HP AN重叠的LP AN进行丢弃处理，从而保证不影响HP AN传输，如图5所示。基站侧在调度时，也并不需要让HP AN对应的DL grant和PDSCH与LP AN PUCCH的起点之间必须满足T1mux和T2mux，也就是基站在调度HP数据时，HP AN对应的DL grant和PDSCH并不需要发送的足够早，可以按照实际需求在HP数据到达并需要发送PDSCH的时候才进行调度和发送，这样即能保证HP数据对应的HP AN的正常的传输，又不限制必须在特定位置之前发送对HP数据的调度和传输，从而降低了对HP数据调度和传输的限制和影响，保证了HP数据随时到达、随时传输的特性。
另一种信道复用的实现方式为：根据HP AN的比特数，以及预先定义或 配置的HP AN的比特数或比特数区间与LP AN的参考比特数之间的对应关系，确定能够与HP AN复用传输的LP AN比特数。具体的，根据对应关系以及当前的HP AN比特数，确定与HP AN复用的LP AN比特数是大于0的，即存在并允许LP AN与HP AN复用传输，则具体处理过程同上述确定支持的情况以及图4，不再赘述。根据对应关系以及当前的HP AN比特数，确定与HP AN复用的LP AN比特数是0，即不存在或不允许LP AN与HP AN复用传输，则具体处理过程同上述确定不支持的情况以及图5，不再赘述。
上述实施例中不同优先级的HARQ-ACK替换为单播和多播的HARQ-ACK，或者替换为其他的两种不同的UCI传输，也同样适用。上述承载UCI的PUCCH中的一个替换为PUSCH，即如果是承载LP AN的PUCCH与承载HP AN的PUSCH之间重叠，或者承载HP AN的PUCCH与承载LP AN的PUSCH重叠，处理方式类似，所不同的就是PUSCH只对应一个UL grant，没有PDSCH和DL grant。
需要说明的是，上述确定不支持(或者说不存在、不允许)LP AN与HP AN复用传输，或者确定与HP AN复用的LP AN的比特数为0的时候，并不一定是在调度和传输上并不存在承载LP AN的PUCCH/PUSCH与承载HP AN的PUCCH/PUSCH重叠，而是实际发生了重叠传输，但配置或决策上确定并不支持两者复用传输，因此需要对低优先级信道进行丢弃处理，不需要对高优先级信道限制满足所述时间条件。
