这里将详细地对示例性实施例进行说明，其示例表示在附图中。下面的描述涉及附图时，除非另有表示，不同附图中的相同数字表示相同或相似的要素。以下示例性实施例中所描述的实施方式并不代表与本公开相一致的所有实施方式。相反，它们仅是与如所附权利要求书中所详述的、本公开的一些方面相一致的装置和方法的例子。
应当理解的是，在本文中提及的“若干个”是指一个或者多个，“多个”是指两个或两个以上。“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。
本公开提供一种混合自动重传请求应答信息发送方法，该混合自动重传请求应答信息发送方法由用户设备执行，能够实现子时隙级别配置的PUCCH信道复用，接下来将结合附图对本公开实施例涉及的混合自动重传请求应答信息发送方法进行详细介绍。
首先，对本公开涉及的一些名词进行解释。
1)用户设备(User Equipment，UE)
在通用移动通信制式中，将终端称之为UE，在本公开实施例中，用户设备可以是手机，智能终端，多媒体设备，流媒体设备等等。
比如，请参考图1，其示出了本公开一个示例性的实施例提供的用户设备的结构示意图。如图1所示，该用户设备包括主板110、外部输出/输入设备120、存储器130、外部接口140、触控系统150以及电源160。
其中，主板110中集成有处理器和控制器等处理元件。
外部输出/输入设备120可以包括显示组件(比如显示屏)、声音播放组件(比如扬声器)、声音采集组件(比如麦克风)以及各类按键等。
存储器130中存储有程序代码和数据。
外部接口140可以包括耳机接口、充电接口以及数据接口等。
触控系统150可以集成在外部输出/输入设备120的显示组件或者按键中，触控系统150用于检测用户在显示组件或者按键上执行的触控操作。
电源160用于对终端中的其它各个部件进行供电。
在本申请实施例中，主板110中的处理器可以通过执行或者调用存储器中存储的程序代码和数据来生成界面内容，将生成的界面内容通过外部输出/输入设备120进行展示。在展示界面内容的过程中，可以通过电容触控系统150检测用户与界面进行交互时执行的触控操作，也可以通过外部输出/输入设备120检测用户与界面进行交互时执行的按键或者其它操作，比如手势操作、语音操作等等。
2)5G超高可靠与低时延通信(5G URLLC)
5G URLLC是5G的三大应用场景之一，具备高可靠、低时延、极高的可用性等全新特性，5G URLLC被业界广泛认为可以应用于工业控制、工厂自动化、智能电网、设备、车联网通讯、远程手术等场景。
3)物理下行共享信道(Physical Downlink Shared channel，PDSCH)
PDSCH用于下行数据的调度传输，可以承载来自上层的不同的传输内容(即不同的逻辑信道)，包括寻呼信息、广播信息、控制信息和业务数据信息等。
4)混合自动重传请求应答(Hybrid Automatic Repeat request acknowledgement，HARQ-ACK)
混合自动重传请求(Hybrid Automatic Repeat Request,HARQ)是一种将前向纠错编码(FEC)和自动重传请求(ARQ)相结合而形成的技术。在接收端使用FEC技术纠正所有错误中能够纠正的那一部分。通过错误检测判断不能纠正错误的数据包。丢弃不能纠错的数据包，向发射端请求重新发送相同的数据包。
5)物理上行链路控制信道(Physical Uplink Control Channel，PUCCH)
PUCCH用于承载上行控制信息(UPlink Control Information，UCI)，UCI信息包括调度请求(scheduling request，SR),HARQ-ACK,信道状态信息(channel state information，CSI)三种。
PUCCH资源集合能够对应的承载一定数量的上行控制信息载荷(UCI payload)，不同的PUCCH资源能够对应承载的UCI payload的范围互不重叠。在现有协议中，对于时隙级别的PUCCH资源配置，PUCCH资源集合0对应的UCI payload为1～2bit，PUCCH资源集合1对应的UCI payload为2～N1bit，PUCCH资源集合2对应的UCI payload为N1+1～N2bit，PUCCH资源集合3对应的UCI payload为N2+1～1706bit，其中N1/N2是可由基站配置的值。一个PUCCH资源可以有格式0～4一共5种格式，可以分为长格式和短格式2种类别，长格式的PUCCH资源占用的时域符号为4～14个，短格式的PUCCH资源占用的时域符号为1～2个。
图2示出了本公开一个实例性实施例提供的通信系统的框图，该通信系统可以包括：接入网22和终端23。
接入网22中包括若干个接入网设备220。接入网设备220可以是基站，所 述基站是一种部署在接入网中用以为终端提供无线通信功能的装置。基站可以包括各种形式的宏基站，微基站，中继站，接入点等等。在采用不同的无线接入技术的系统中，具备基站功能的设备的名称可能会有所不同，在第五代移动通信(the 5th generation mobile communication，5G)，也称新空口(New Radio，NR)系统中，称为演进型Node B(Evolved Node B，eNodeB或者eNB)。随着通信技术的演进，“基站”这一描述可能会变化。为方便本申请实施例中，上述为终端23提供无线通信功能的装置统称为接入网设备。
终端23可以包括各种具有无线通信功能的手持设备、车载设备、可穿戴设备、计算设备或连接到无线调制解调器的其他处理设备，以及各种形式的用户设备，移动台(Mobile Station，MS)，终端(terminal device)等等。为方便描述，上面提到的设备统称为终端。接入网设备220与终端23之间通过某种空口技术互相通信，例如Uu接口(User Equipment与UMTS Terrestrial Radio Access Network之间的接口)。
国际电信联盟(International Telecommunication Union，ITU)把5G网络中的业务分为3大类。第一类是eMMB(enhanced Mobile Broadband，增强移动宽带)，eMMB是专门为手机等移动设备服务的5G业务类型。第二类则是URLLC，这种业务主要将被应用于工业用途和自动驾驶车辆。第三类是mMTC(massive Machine Type Communications，大规模物联网)，mMTC是“物联网”和“万物互联”场景中将被使用的业务类型，mMTC的长处是让大量相邻设备同时享受顺畅的通信连接。
其中，URLLC业务通常会要求非常高的可靠性和非常低的时延，eMBB业务类型通常会要求较高的速率，但是并不会要求非常低的时延和非常低的错误率。因而比较起来，URLLC业务类型的优先级会更高一些。当两者空口时频域资源发生冲突时，优先保证URLLC业务的传输，并通过下行控制指示通知UE。这种机制使得URLLC数据以相当高的优先级发送，提升URLLC传输的可靠性。
图3是根据一示例性实施例示出的一种混合自动重传请求应答信息发送方法的流程图，该混合自动重传请求应答信息发送方法由用户设备执行，比如，该用户设备可以是如图1所示的用户设备。如图3所示，该混合自动重传请求应答信息发送方法包括：
步骤310，获取至少两个承载HARQ-ACK信息的PUCCH信道，该至少两个承载HARQ-ACK信息的PUCCH信道相互重叠且分别归属于不同的子时隙。
其中，上述不同的子时隙属于同一个时隙。也就是说，系统将一个时隙划分成多个子时隙，每个子时隙对应有一个发送HARQ-ACK信息的机会，从而缩短HARQ-ACK信息发送的时延。
在本公开实施例中，每个子时隙都可以由基站配置PUCCH资源，每个子时隙配置的PUCCH资源可以相同或者不同，且每个子时隙可以配置最多4个PUCCH资源集合，每个PUCCH资源集合中有多个PUCCH资源，这多个PUCCH资源可以使用PUCCH资源ID区分。
在一种可能的实现方式中，不同的子时隙中的至少两个承载HARQ-ACK信息的PUCCH信道处于同一时隙中，或者，处于相邻的两个时隙中。
请参考图4，其示出了本公开一个示例性实施例提供的获取至少两个承载HARQ-ACK信息的PUCCH信道的示意图。如图4所示，以两个归属于不同的子时隙的PUCCH信道的复用为例，系统将一个包含14个时域符号的时隙划分成7个子时隙，每个子时隙包含2个时域符号，其中，URLLC PDSCH1(410)归属于子时隙0，URLLC PDSCH2(420)归属于子时隙1，HARQ-ACK1信息(430)归属于子时隙3，HARQ-ACK2信息(440)归属于子时隙5，URLLC PDSCH1(410)对应的HARQ-ACK1信息(430)的PUCCH信道和URLLC PDSCH2(420)对应的HARQ-ACK2信息(440)的PUCCH信道在时域上存在重叠。
步骤320，当至少两个承载HARQ-ACK信息的PUCCH信道满足复用的时序条件时，将至少两个HARQ-ACK信息复用到至少两个不同的子时隙中的目标子时隙的PUCCH资源上。
当图4中所示的承载HARQ-ACK1信息(430)的PUCCH信道和承载HARQ-ACK2信息(440)的PUCCH信道满足复用的时序条件时，用户设备可以将两个HARQ-ACK信息复用到两个不同的子时隙中的目标子时隙的PUCCH资源上，也就是将承载在不同的PUCCH信道上的HARQ-ACK信息复用在一起，并将复用后的HARQ-ACK信息承载到两个PUCCH信道中的其中一个PUCCH信道的PUCCH资源上。
在一种可能的实现方式中，该目标子时隙是该至少两个不同的子时隙中， 起始时间最早的子时隙，由此可以尽量早的发送复用后的HARQ-ACK信息。
在一种可能的实现方式中，当该至少两个承载HARQ-ACK信息的PUCCH信道满足复用的时序条件时，将该至少两个HARQ-ACK信息复用到至少两个不同的子时隙中的目标子时隙的PUCCH资源上之前，还包括：
根据至少两个HARQ-ACK信息的比特数，从该目标子时隙对应的各个PUCCH资源集合中确定目标PUCCH资源集合；
根据目标下行控制信息DCI中的PUCCH资源的指示，从该目标PUCCH资源集合中确定该目标资源；该目标DCI是该至少两个HARQ-ACK信息各自对应的DCI中的一个。
在一种可能的实现方式中，该目标DCI是该至少两个HARQ-ACK信息各自对应的DCI中，DCI的发送时间最晚的一个DCI。
在一种可能的实现方式中，该至少两个承载HARQ-ACK信息的PUCCH信道满足复用的时序条件是指：
当该至少两个承载HARQ-ACK信息的PUCCH信道在子时隙上两两重叠时，获取第一时域位置和第二时域位置，该第一时域位置是该至少两个HARQ-ACK信息对应的至少两个PDSCH的结束符号位置中最晚的结束符号位置，该第二时域位置是该至少两个承载HARQ-ACK信息的PUCCH信道中时间最早的开始符号位置；
当第一时域位置处于第二时域位置之前，且第一时域位置和第二时域位置之间的间隔不小于间隔阈值时，确定至少两个承载HARQ-ACK信息的PUCCH信道满足复用的时序条件。
在一种可能的实现方式中，该方法还包括：
当至少两个承载HARQ-ACK信息的PUCCH信道不满足复用的时序条件时，丢弃至少不同的两个子时隙中，除了第一子时隙之外的其它各个子时隙对应的HARQ-ACK信息。
在一种可能的实现方式中，该第一子时隙是该至少两个子时隙中，起始时间最早的子时隙。
综上所述，本公开实施例所示的混合自动重传请求应答信息发送方法，通过获取分别归属于不同子时隙的至少两个承载HARQ-ACK信息的PUCCH信道，当至少两个承载HARQ-ACK信息的PUCCH信道满足复用条件时，将至少 两个承载HARQ-ACK信息复用到至少两个不同子时隙的目标子时隙的PUCCH资源上，从而提供了一种当子时隙级别配置的承载HARQ-ACK信息的多个PUCCH资源有重叠的情况下，对HARQ-ACK信息进行复用的方案，避免了PUCCH信道在时域重叠的情况。
结合图3和图4所示的方案，请参考图5，其中，图5是根据一示例性实施例示出的一种混合自动重传请求应答信息发送方法的流程图，该混合自动重传请求应答信息发送方法由用户设备执行，比如，该用户设备可以是如图1所示的用户设备。如图5所示，该混合自动重传请求应答信息发送方法包括：
步骤510，获取至少两个承载HARQ-ACK信息的PUCCH信道，该至少两个承载HARQ-ACK信息的PUCCH信道相互重叠且分别归属于不同的子时隙。
上述步骤510的实现过程可以参考上述图3所示实施例中的相关描述，此处不再赘述。
步骤520，当至少两个承载HARQ-ACK信息的PUCCH信道满足复用的时序条件时，根据至少两个HARQ-ACK信息的比特数，从目标子时隙对应的各个PUCCH资源集合中确定目标PUCCH资源集合。
在一种可能的实现方式中，目标子时隙是至少两个不同的子时隙中，起始时间最早的子时隙。
例如，如图4所示，URLLC PDSCH1(410)归属于子时隙0，URLLC PDSCH2(420)归属于子时隙1，当URLLC PDSCH1(410)对应的HARQ-ACK1信息(430)的PUCCH信道和URLLC PDSCH2(420)对应的HARQ-ACK2信息(440)的PUCCH信道满足复用时序条件时，由于子时隙0的起始时间早于子时隙1的起始时间，因此，用户设备可以将子时隙0作为目标子时隙。
在一种可能的实现方式中，当至少两个承载HARQ-ACK信息的PUCCH信道在子时隙上两两重叠时，获取第一时域位置和第二时域位置，该第一时域位置是至少两个HARQ-ACK信息对应的至少两个PDSCH的结束符号位置中最晚的结束符号位置，该第二时域位置是至少两个承载HARQ-ACK信息的PUCCH信道中时间最早的起始符号位置；
当第一时域位置处于第二时域位置之前，且第一时域位置和第二时域位置之间的间隔不小于间隔阈值时，确定至少两个承载HARQ-ACK信息的PUCCH 信道满足复用的时序条件。请参考图6，图6示出了本公开一个示例性实施例提供的资源位置示意图。如图6所示，PDSCH2(670)的结束符号位置晚于PDSCH2(660)的结束符号位置，因此将PDSCH2(670)的结束符号位置确定为第一时域位置，承载HARQ-ACK1信息(630)的PUCCH信道的开始符号位置早于承载HARQ-ACK2信息(640)的PUCCH信道的开始符号位置，因此将承载HARQ-ACK1信息(630)的PUCCH信道的开始符号位置确定为第二时域位置。
当第一时域位置与第二时域位置之间的时间间隔T 1大于等于预定的复用时间间隔T时，也就是图6中的第一时域位置与第二时域位置之间的时间间隔650大于或者等于预定义的复用时间间隔T时，确定图6所示的两个承载HARQ-ACK信息的PUCCH信道满足复用的时序条件。
其中预定的复用时间间隔T是在协议中预定义的，其可能与子载波间隔等参数相关。
请参考图7，其示出了本公开一个示例性实施例提供的HARQ-ACK信息的PUCCH信道判断复用的时序条件的示意图。如图7所示，以两个归属于不同的子时隙的PUCCH信道的复用为例，系统将一个包含14个时域符号的时隙划分成7个子时隙，每个子时隙包含2个时域符号，其中URLLC PDSCH1(710)归属于子时隙0，URLLC PDSCH2(720)归属于子时隙1，HARQ-ACK1信息(730)归属于子时隙4，HARQ-ACK2信息(740)归属于子时隙5,URLLC PDSCH1(710)对应的HARQ-ACK1信息(730)的PUCCH信道和URLLC PDSCH2(720)对应的HARQ-ACK2信息(740)的PUCCH信道在时域重叠，但属于不同的信道。
第一时域位置是指URLLC PDSCH2(720)的结束符号位置，第二时域位置是指承载HARQ-ACK1信息(730)的PUCCH信道的开始符号位置，两者之间的时间间隔T 1为3个符号，假定复用时间间隔T为3个符号，那么图7所示的两个HARQ-ACK信息满足复用的时序条件，因此UE将对两个HARQ-ACK信息进行复用，并将复用后的HARQ-ACK信息承载到步骤530所确定的目标资源上，也就是说UE将在HARQ-ACK1信息(730)归属的子时隙4中配置的多个PUCCH资源中选出一个PUCCH资源，可以将复用后的HARQ-ACK信息承载到该PUCCH资源上。
在本公开实施例中，一个HARQ-ACK码本可以由一个或者多个PDCCH的 HARQ-ACK信息比特数组成，UE通过HARQ-ACK码本中的HARQ-ACK信息的比特数来选择对应的PUCCH资源集合。
步骤530，根据目标下行控制信息DCI中的PUCCH资源的指示，从目标PUCCH资源集合中确定目标资源；该目标DCI是至少两个HARQ-ACK信息各自对应的DCI中的一个。
在一种可能的实现方式中，该目标DCI是至少两个HARQ-ACK信息各自对应的DCI中，DCI的发送时间最晚的一个DCI。
如图6所示，HARQ-ACK1信息(630)对应DCI(610)，HARQ-ACK2信息(640)对应DCI2(620)，DCI1与DCI2中对应的PUCCH资源的指示，为使得基站可以在较晚发送的DCI中灵活的更改指示的具体的PUCCH资源ID，用户设备可以选取DCI的发送时间最晚的一个DCI为目标DCI，例如，图6中DCI2的发送时间交DCI1的发送时间晚，因此，用户设备可以选取DCI2为目标DCI，并根据DCI2中的PUCCH资源的指示，从目标PUCCH资源集合中确定出目标资源。
在一种可能的实现方式中，该目标DCI是至少两个HARQ-ACK信息各自对应的DCI中，DCI的发送时间最早的一个DCI，以使得用户设备可以尽量早的传输HARQ-ACK信息，避免不必要的时延。
步骤540，将至少两个HARQ-ACK信息复用到至少两个不同的子时隙中的目标子时隙的PUCCH资源上。
在一种可能的实现方式中，当至少两个承载HARQ-ACK信息的PUCCH信道不满足复用的时序条件时，丢弃至少不同的两个子时隙中，除了第一子时隙之外的其它各个子时隙对应的HARQ-ACK信息。
在一种可能的实现方式中，该第一子时隙是至少两个子时隙中，起始时间最早的子时隙。
如图4所示，根据上述说明，图4中的第一时域位置是指URLLC PDSCH2(420)的结束符号位置，第二时域位置是指承载HARQ-ACK1信息的PUCCH信道的开始符号位置，两者之间的时间间隔T 1为2个符号，假定复用时间间隔T为3个符号，那么图4所示的两个HARQ-ACK信息不满足复用的时序条件，此时，UE可以将传输较早的子时隙中的HARQ-ACK信息，即HARQ-ACK1信息所在的子时隙0为第一子时隙，UE将传输HARQ-ACK1信息，并将与之重 叠的HARQ-ACK2信息丢弃。
请参考图8，其示出了本公开一个示例性实施例提供的HARQ-ACK信息的PUCCH信道判断复用的时序条件的示意图。如图8所示，以三个归属于不同的子时隙的PUCCH信道的复用为例，系统将两个分别包含14个时域符号的时隙分别划分成7个子时隙，每个子时隙包含2个时域符号，其中URLLC PDSCH1(810)归属于时隙1的子时隙6，URLLC PDSCH2(820)归属于时隙2的子时隙0，URLLC PDSCH2(830)归属于时隙2的子时隙1，HARQ-ACK1信息(840)归属于时隙2的子时隙2，HARQ-ACK2信息(850)归属于时隙2的子时隙4，HARQ-ACK3信息(860)归属于时隙2的子时隙5，URLLC PDSCH1(810)对应的HARQ-ACK1信息(840)的PUCCH信道和URLLC PDSCH2(820)对应的HARQ-ACK2信息(850)的PUCCH信道在时域重叠，URLLC PDSCH2(820)对应的HARQ-ACK2信息(850)的PUCCH信道和URLLC PDSCH3(830)对应的HARQ-ACK3信息(860)的PUCCH信道在时域上存在重叠。
在如图8所示的情况下，用户设备先对第一个PUCCH信道以及与第一个PUCCH信道重叠的PUCCH信道是否满足复用时序条件进行判断，若满足复用的时序条件，则对两个信道所承载的HARQ-ACK信息进行复用，并将复用后的HARQ-ACK信息承载到子时隙中最早的子时隙中的目标资源上；若不满足复用条件，则传输两个信道所承载的HARQ-ACK信息中传输较早的子时隙中的HARQ-ACK信息，而与之重叠的HARQ-ACK2信息将会被丢弃。
若承载复用后的HARQ-ACK信息的PUCCH信道与承载第三个HARQ-ACK信息的PUCCH信道不重叠，则仍然可以传输第三个HARQ-ACK信息，若承载复用后的HARQ-ACK信息的PUCCH信道与承载第三个HARQ-ACK信息的PUCCH信道重叠，则将继续进行上述图5所述的步骤。
也就是说，UE先对承载HARQ-ACK1信息(840)的PUCCH信道与承载HARQ-ACK2信息(850)的PUCCH信道是否满足复用时序条件进行判断，若满足复用的时序条件，则UE对两个信道所承载的HARQ-ACK信息进行复用，并将复用后的HARQ-ACK信息承载到HARQ-ACK1信息(840)归属的时隙1的子时隙6中配置的PUCCH资源中的目标资源上；若不满足复用条件，则UE将传输HARQ-ACK1信息(840)，而与之重叠的HARQ-ACK2信息(850)将会被丢弃。
若承载复用后的HARQ-ACK信息的PUCCH信道与承载HARQ-ACK3信息(860)的PUCCH信道不重叠，则仍可以传输HARQ-ACK3信息(860)；若承载复用后的HARQ-ACK信息的PUCCH信道与承载HARQ-ACK3信息(860)的PUCCH信道重叠，则将则将继续进行上述图5所述的步骤。
在一种可能的情况下，多个(例如3个或者3个以上)承载HARQ-ACK信息的信道两两重叠，则用户设备对多个承载HARQ-ACK信息的信道一起判断是否满足复用的时序条件，如果满足，则将多个HARQ-ACK信息复用到子时隙最早的子时隙中配置的多个PUCCH资源中的目标资源上，如果不满足，则只传输子时隙最早的HARQ-ACK信息，与其重叠的HARQ-ACK信息将被丢弃。
例如，请参考图9，图9示出了其示出了本公开一个示例性实施例提供的HARQ-ACK信息的PUCCH信道判断复用的时序条件的示意图。如图9所示，以三个归属于不同的子时隙的PUCCH信道的复用为例，系统将两个分别包含14个时域符号的时隙分别划分成7个子时隙，每个子时隙包含2个时域符号，其中URLLC PDSCH1(910)归属于时隙1的子时隙6，URLLC PDSCH2(920)归属于时隙2的子时隙0，URLLC PDSCH2(930)归属于时隙2的子时隙1，HARQ-ACK1信息(940)归属于时隙2的子时隙3，HARQ-ACK2信息(950)归属于时隙2的子时隙4，HARQ-ACK3信息(960)归属于时隙2的子时隙4，URLLC PDSCH1(910)对应的HARQ-ACK1信息(940)的PUCCH信道、URLLC PDSCH2(920)对应的HARQ-ACK2信息(950)的PUCCH信道以及URLLC PDSCH3(930)对应的HARQ-ACK3信息(960)的PUCCH信道在时域上两两重叠。
在图9所示的情况下，UE对分别承载HARQ-ACK1信息(940)、HARQ-ACK2信息(950)以及HARQ-ACK3信息(960)的信道一起进行判断是否满足复用的时序条件，如果满足，则UE将HARQ-ACK1信息(940)、HARQ-ACK2信息(950)以及HARQ-ACK3信息(960)进行复用，并将复用后的HARQ-ACK信息承载到HARQ-ACK1信息(940)归属的时隙1的子时隙6中配置的PUCCH资源中的目标资源上；若不满足复用条件，则UE将传输HARQ-ACK1信息(940)，而与之重叠的HARQ-ACK2信息(950)和HARQ-ACK3信息(960)将会被丢弃。
综上所述，本公开实施例所示的混合自动重传请求应答信息发送方法，通 过获取分别归属于不同子时隙的至少两个承载HARQ-ACK信息的PUCCH信道，当至少两个承载HARQ-ACK信息的PUCCH信道满足复用条件时，将至少两个承载HARQ-ACK信息复用到至少两个不同子时隙的目标子时隙的PUCCH资源上，从而提供了一种当子时隙级别配置的承载HARQ-ACK信息的多个PUCCH资源有重叠的情况下，对HARQ-ACK信息进行复用的方案，避免了PUCCH信道在时域重叠的情况。
