Description

混合自动重传请求确认HARQ-ACK的传输方法及装置 技术领域
本公开涉及通信技术领域，尤其涉及一种混合自动重传请求确认HARQ-ACK的传输方法及装置。
背景技术
现在的系统针对UE(User Equipment，用户设备)侧，不会同时存在多个单播(unicast)传输的情况，也不会同时存在单播与组播(groupcast)同时存在的场景，而且也不支持针对组播的HARQ-ACK(Hybrid Automatic Repeat Request Acknowledgement，混合式自动重送请求确认)。
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，透过ACK/NACK决定是否要重送。HARQ的关键词是存储、请求重传、合并解调。HARQ的重传基于ACK/NACK，HARQ的ACK/NACK回报，是以1比特的信号(signaling)来做快速且频繁地回报。
在RAN1-94b会议上，通过了NR(New Radio)V2X(Vehicle-to-Everything，车联万物)的侧链路(sidelink)上要同时支持单播与组播传输的HARQ-ACK，并会在R16中仔细研究这两种HARQ feedback(反馈)方式。
在R15的NR研究中以及之前的LTE(Long Term Evolution，长期演进)研究中，只有针对单播的HARQ反馈。在R15的研究中，有讨论针对单播的HARQ反馈与SR(Scheduling Request，调度请求)以及CSI(Channel State Information，信道状态信息)反馈的碰撞规则的讨论。

具体实施方式
以下将参考附图详细说明本公开的各种示例性实施例、特征和方面。附图中相同的附图标记表示功能相同或相似的元件。尽管在附图中示出了实施例的各种方面，但是除非特别指出，不必按比例绘制附图。
在这里专用的词“示例性”意为“用作例子、实施例或说明性”。这里作为“示例性”所说明的任何实施例不必解释为优于或好于其它实施例。
另外，为了更好的说明本公开，在下文的具体实施方式中给出了众多的具体细节。本领域技术人员应当理解，没有某些具体细节，本公开同样可以实施。在一些实例中，对于本领域技术人员熟知的方法、手段、元件和电路未作详细描述，以便于凸显本公开的主旨。
在V2X通信中，侧链路数据的传输和接收可以采用HARQ技术，透过ACK/NACK决定是否要重送。在RAN1-94b会议上，通过了NR V2X的侧链路上要同时支持单播与组播传输的HARQ-ACK反馈。本公开针对在NR V2X的侧链路上，单播与组播传输的HARQ-ACK发生碰撞，以及多个单播/组播传输的HARQ-ACK发生碰撞时，如何传输HARQ-ACK的问题。
其中，HARQ-ACK信息可以是单播传输的PSSCH(Pysical Sidelink Share Channel，物理侧链路共享信道)或者PSCCH(Pysical Sidelink Control Channel，物理侧链路控制信道)对应的ACK或者NACK信息，也可以是组播传输的PSSCH或者PSCCH对应的ACK或者NACK信息，或者同时包含单播与组播传输的PSSCH或者PSCCH对应的ACK或者NACK信息。
其中，HARQ-ACK信息可以由PSCCH或者PSSCH或者PSFCH(Physical Sidelink Feedback Channel， 物理侧链路反馈信道)或者PUCCH(Physical Uplink Control Channel，物理上行链路控制信道)或者PUSCH(Physical Uplink Shared Channel，物理上行链路共享信道)来承载。因此，HARQ-ACK碰撞又可以是指承载HARQ-ACK信息的信道的碰撞，例如，PSFCH发生了碰撞。下文将以HARQ-ACK碰撞为例进行介绍，本领域技术人员可以理解，HARQ-ACK碰撞其实也可以指PSFCH碰撞，HARQ-ACK都可以用PSFCH替代。
Uu链路的定义是用户设备与eNB(evolved NodeB)之间的无线协议或者用户设备与gNB之间的无线通信协议或者是用户设备与基站之间的无线通信协议。Sidelink指的是在没有基站参与的前提下用户设备与用户设备之间的通信协议。
下文中出现的高层信令具体可以是RRC(Radio Resource Control，无线资源控制)信令或者MAC-CE(MAC Control Element，MAC控制单元)信令。
下文中出现的HARQ-ACK、SR、CSI反馈如果通过UCI(uplink control information,上行控制信息)或者SL-UCI(sidelink uplink control information，侧链路上行控制信息)或者SFCI(Sidelink feedback control information,侧链路反馈控制信息)，可以采用不同的PUCCH格式或者SL-PUCCH格式或者SFCI格式。其中，不同的PUCCH格式或者SL-PUCCH格式或者SFCI格式可以有各自的承载比特数要求和或传输所占有的符号数要求。本公开具体不做具体限制，适用于各种PUCCH格式或者SL-PUCCH格式发生碰撞的情形。
下文中出现的HARQ-ACK之间的碰撞，可以适用于基站没有配置simultaneous-HARQ资源和或simultaneous-HARQ指示的情况。其中，simultaneous-HARQ资源是用于承载发生了碰撞的HARQ-ACK；simultaneous-HARQ指示可以用来指示UE可以把发生了碰撞的HARQ-ACK放在simultaneous-HARQ资源上来承载。
下文中出现的HARQ-ACK与CSI反馈之间的碰撞，可以适用于基站没有配置simultaneous-HARQ-CSI资源和或simultaneous-HARQ-CSI指示的情况。其中，simultaneous-HARQ-CSI资源是用于承载发生了碰撞的HARQ-ACK与CSI反馈；simultaneous-HARQ-CSI指示可以用来指示UE可以把发生了碰撞的HARQ-ACK与CSI反馈放在simultaneous-HARQ-CSI资源上来承载。
下文中出现的HARQ-ACK与SR之间的碰撞，可以适用于基站没有配置simultaneous-HARQ-SR资源和或simultaneous-HARQ-SR指示的情况。其中，simultaneous-HARQ-SR资源是用于承载发生了碰撞的HARQ-ACK与SR；simultaneous-HARQ-SR指示可以用来指示UE可以把发生了碰撞的HARQ-ACK与SR放在simultaneous-HARQ-SR资源上来承载。
在一种可能的实现方式中，本公开提供了一种混合自动重传请求确认HARQ-ACK的传输方法，或者说一种物理侧链路反馈信道PSFCH的传输方法，所述方法应用于用户设备UE，所述方法包括：在PSFCH发生了碰撞时，根据优先级规则选择第一PSFCH；其中，优先级规则至少基于PSFCH关联的PSSCH的优先级，其中，PSSCH的优先级可以通过PSCCH指示；传输所述第一PSFCH，其中，传输包括发送和接收。
在一种可能的实现方式中，所述第一PSFCH对应的物理侧链路共享信道PSSCH的优先级最高。
下文中通过多个不同场景下的PSFCH发生了碰撞的情景对本公开的PSFCH的传输方法进行说明。
该实施例的方法可以应用于多个单播传输的HARQ-ACK之间发生了碰撞的场景。
图1示出根据本公开一实施例的HARQ-ACK的传输方法的流程图。如图1所示，该方法可以包括：
步骤S11，在多个单播传输的HARQ-ACK之间发生了碰撞时，从所述多个单播传输的HARQ-ACK中选择符合第一预设条件的第一HARQ-ACK；
步骤S12，传输所述第一HARQ-ACK。
其中，第一预设条件可以为HARQ-ACK对应的物理侧链路共享信道PSSCH的优先级最高、HARQ-ACK对应的时域资源或者信道的第一个符号的位置最靠前，等等。HARQ-ACK对应的PSSCH可以是指承载所述HARQ-ACK的信道，HARQ-ACK对应的时域资源或者信道可以是指承载所述HARQ-ACK的时域资源或者信道。
其中，HARQ-ACK对应的PSSCH的优先级可以通过PSSCH所承载的传输对应的PPPP(ProSe Per-Packet Priority，近距离通信数据分组优先级)确定，PPPP的数值越低代表着其对应的传输的优先级越高，PPPP可以通过SCI(Sidelink Control Information，侧链路控制信息)或者高层信令指示。其中，PPPP的数值可以与QoS优先级(priority)，时延(latency)，可靠性(reliability)和最小要求通信距离(minimum required communication range)中的至少一种参数相关。
其中，发生了碰撞可以是承载HARQ-ACK的时频资源或者信道在时间上发生了重叠或者部分重叠，或者可以是承载HARQ-ACK的时频资源或者信道在时间和频域上发生了重叠或者部分重叠。
在一个示例中，以第一预设条件为HARQ-ACK对应的PSSCH的优先级最高为例，当UE的多个侧链路上的单播传输的HARQ-ACK发生了碰撞时，UE可以通过HARQ-ACK对应的PSSCH所承载的传输对应的PPPP确定多个单播传输的HARQ-ACK对应的PSSCH的优先级，选择优先级最高的PSSCH所承载的单播传输的HARQ-ACK作为所述第一HARQ-ACK，并传输第一HARQ-ACK至相应的UE或者基站。举例来说，UE的3个侧链路上的单播传输的HARQ-ACK(HARQ-ACK1、HARQ-ACK2、HARQ-ACK3)发生了碰撞，HARQ-ACK1、HARQ-ACK2、HARQ-ACK3对应的PSSCH所承载的传输对应的PPPP分别为1、2、3，第一HARQ-ACK为HARQ-ACK1。
其中，如果存在多个HARQ-ACK对应的PSCCH的优先级并列最高的情况时，此时可以基于下列准则之一选择第一HARQ-ACK：
1.选择发生碰撞的承载HARQ-ACK的时频资源或者信道之中第一个symbol最靠前的时频资源或者信道所承载的HARQ-ACK作为所述第一HARQ-ACK；
2.选择发生碰撞的承载HARQ-ACK的时频资源或者信道之中第一个symbol最靠后的时频资源或者信道所承载的HARQ-ACK作为所述第一HARQ-ACK；
3.选择发生碰撞的承载HARQ-ACK的时频资源或者信道之中时域上占用symbol数目最多的时频资源或者信道所承载的HARQ-ACK作为所述第一HARQ-ACK；
4.选择发生碰撞的承载HARQ-ACK的时频资源或者信道之中时域上占用symbol数目最少的时频资源或者信道所承载的HARQ-ACK作为所述第一HARQ-ACK；
5.选择发生碰撞的承载HARQ-ACK的时频资源或者信道之中的任意一个时频资源或者信道所承载的HARQ-ACK作为所述第一HARQ-ACK。
在另一个示例中，以第一预设条件为HARQ-ACK对应的时域资源或者信道的第一个符号(symbol)的位置最靠前为例，当UE的多个侧链路上的单播传输的HARQ-ACK发生了碰撞时，UE可以确定每个 HARQ-ACK对应的时域资源或者信道的第一个symbol的位置，例如，第一个symbol在时隙中的位置，将第一个symbol在时隙中的位置最靠前的HARQ-ACK作为所述第一HARQ-ACK，并传输第一HARQ-ACK至相应的UE或者基站。
需要说明的是，尽管以优先级和第一符号的位置作为示例介绍了HARQ-ACK的传输方法如上，但本领域技术人员能够理解，本公开应不限于此。事实上，用户完全可根据个人喜好和/或实际应用场景灵活设定第一预设条件，只要能够实现HARQ-ACK的正常传输即可。
根据本公开上述实施例的方法，通过设置第一预设条件，在多个单播传输的HARQ-ACK之间发生了碰撞时，选择符合第一预设条件的HARQ-ACK进行传输，实现了多个单播传输的HARQ-ACK发生碰撞时仍然能够正常传输HARQ-ACK。
图2示出根据本公开一实施例的HARQ-ACK的传输方法的流程图。
在一种可能的实现方式中，如图2所示，所述方法还可以包括：
步骤S13，若多个单播传输的HARQ-ACK对应的时域资源或者信道的第一个符号的位置相同，则选择多个单播传输的HARQ-ACK中对应的时域持续时长(duration)最长或者最短的HARQ-ACK作为所述第一HARQ-ACK、或者选择多个单播传输的HARQ-ACK中的任意一个HARQ-ACK作为所述第一HARQ-ACK。
在一个示例中，多个单播传输的HARQ-ACK对应的时域资源或者信道的第一个symbol的位置相同(也就是说并列最靠前)，UE可以根据HARQ-ACK的时域资源的时域duration来判断如何传输HARQ-ACK。例如，可以选择时域duration最长或者最短的HARQ-ACK作为第一HARQ-ACK。
在另一个示例中，多个单播传输的HARQ-ACK对应的时域资源或者信道的第一个symbol的位置相同(也就是说并列最靠前)，UE可以随机选择任意一个HARQ-ACK作为第一HARQ-ACK，也就是UE可以基于UE实现来传输多个单播传输的HARQ-ACK中的任意一个HARQ-ACK。
通过上述实施例的HARQ-ACK的传输方法，在多个单播传输的HARQ-ACK对应的时域资源或者信道的第一个symbol的位置相同，仍然可以实现HARQ-ACK正常传输。
图3示出根据本公开一实施例的混合自动重传请求确认HARQ-ACK的传输方法的流程图。
如图3所示，在一种可能的实施方式中，所述方法还可以包括：
步骤S14，丢弃所述多个单播传输的HARQ-ACK中除了所述第一HARQ-ACK之外的HARQ-ACK。
或者，
步骤S15，将所述多个单播传输的HARQ-ACK中除了所述第一HARQ-ACK之外的HARQ-ACK按照PSSCH的优先级由高到低依次推迟到下一个可传输机会进行传输。
或者，
步骤S16，将所述多个单播传输的HARQ-ACK中除了所述第一HARQ-ACK之外的HARQ-ACK按照时域资源或者信道的第一个符号的位置由前到后依次推迟到下一个可传输机会进行传输。
其中，步骤S14、步骤S15、步骤S16可以在步骤S12之后执行。
对于步骤S14，举例来说，UE的3个侧链路上的单播传输的HARQ-ACK(HARQ-ACK1、HARQ-ACK2、HARQ-ACK3)发生了碰撞，HARQ-ACK1、HARQ-ACK2、HARQ-ACK3对应的PSSCH所承载的传输对应的PPPP分别为1、2、3，第一HARQ-ACK为HARQ-ACK1。UE可以传输HARQ-ACK1， 丢弃HARQ-ACK2、HARQ-ACK3。
下一个可传输机会，可以是根据用于承载HARQ-ACK的周期性时频资源的周期配置，得到下一个可以用于传输的HARQ-ACK的资源所在的时域以及频域位置作为下一个可传输机会。
对于步骤S15，仍然以上述示例为例，对于HARQ-ACK2、HARQ-ACK3，可以在下一个可传输机会到来时，如果满足传输条件则传输HARQ-ACK2，否则，则顺延至下一个传输机会；在HARQ-ACK2传输完后，在下一个可传输机会到来时，如果满足传输条件则传输HARQ-ACK3，否则，则顺延至下一个传输机会。
对于步骤S16，举例来数，UE的3个侧链路上的单播传输的HARQ-ACK(HARQ-ACK1、HARQ-ACK2、HARQ-ACK3)发生了碰撞，HARQ-ACK1、HARQ-ACK2、HARQ-ACK3对应的时域资源的第一个符号的位置：HARQ-ACK1最靠前、HARQ-ACK2比HARQ-ACK3靠前。UE可以传输HARQ-ACK1，对于HARQ-ACK2、HARQ-ACK3，可以在下一个可传输机会到来时，如果满足传输条件则传输HARQ-ACK2，否则，则顺延至下一个传输机会；在HARQ-ACK2传输完后，在下一个可传输机会到来时，如果满足传输条件则传输HARQ-ACK3，否则，则顺延至下一个传输机会
通过上述实施方式的HARQ-ACK的传输方法，在多个单播传输的HARQ-ACK之间发生了碰撞时，可以实现所有HARQ-ACK正常传输。
在一种可能的实现方式中，所述方法还可以包括：将所述多个单播传输的HARQ-ACK中除了所述第一HARQ-ACK之外的HARQ-ACK根据时域持续时长的长短按顺序依次推迟到下一个可传输机会进行传输。比如，可以按照时域持续时长的长短由长到短依次推迟到下一个可传输机会进行传输，或者可以按照时域持续时长的长短由短到长依次推迟到下一个可传输机会进行传输。
图4示出根据本公开一实施例的HARQ-ACK的传输方法的流程图。
如图4所示，在一种可能的实施方式中，所述方法还可以包括：
步骤S17，在多个单播传输的HARQ-ACK之间发生了碰撞时，将多个HARQ-ACK以及每个HARQ-ACK对应的目的地址复用(multiplexing)到物理上行链路控制信道PUCCH进行传输。
其中，HARQ-ACK对应的目的地址可以是指UE将该HARQ-ACK发送到另一个UE的地址或者是指该HARQ-ACK对应的PSCCH的发射源用户。复用到PUCCH可以是指复用到PSCCH或者UCI(Uplink Control Information，上行控制信息)或者SL-UCI(Sidelink Uplink Control Information，侧链路上行控制信息)或者SFCI内。
举例来说，当UE的多个侧链路上的单播传输的HARQ-ACK发生了碰撞时，UE可以确定UE的多个侧链路另一端连接的UE的地址，例如，UE的多个侧链路包括侧链路1、侧链路2和侧链路3，另一端分别连接UE1、UE2、UE3，侧链路1、侧链路2和侧链路3上的单播传输的HARQ-ACK分别为HARQ-ACK1、HARQ-ACK2、HARQ-ACK3。那么，HARQ-ACK1对应的目的地址为UE1的地址Destination-ID1，HARQ-ACK2对应的目的地址为UE2的地址Destination-ID2，HARQ-ACK3对应的目的地址为UE3的地址Destination-ID3。UE可以将HARQ-ACK1、HARQ-ACK2、HARQ-ACK3，以及Destination-ID1、Destination-ID2、Destination-ID3复用在SL-UCI或者SFCI内，传输给UE1、UE2、UE3。
SL-UCI或者SFCI：
Destination-ID field-1：1
HARQ-ACK field-1：0
Destination-ID field-2：2
HARQ-ACK field-2：1
Destination-ID field-3：3
HARQ-ACK field-3：1
这样，UE1、UE2、UE3在接收到SL-UCI或者SFCI后，就去Destination-ID对应的HARQ-ACK field读取之前的单播传输对应的HARQ-ACK。例如，U1去Destination-ID field-1对应的HARQ-ACK field-1读取之前的单播传输对应的HARQ-ACK。U2去Destination-ID field-2对应的HARQ-ACK field-2读取之前的单播传输对应的HARQ-ACK。U3去Destination-ID field-3对应的HARQ-ACK field-3读取之前的单播传输对应的HARQ-ACK。
在一种可能的实现方式中，还可以将UE的源地址(Source ID)复用(multiplexing)到PUCCH。
通过上述实施方式的HARQ-ACK的传输方法，在多个单播传输的HARQ-ACK之间发生了碰撞时，可以实现所有HARQ-ACK正常传输。
在一种可能的实现方式中，本公开还提供了一种混合自动重传请求确认HARQ-ACK的传输方法，所述方法应用于用户设备UE，该实施例的方法应用于多个组播传输的HARQ-ACK之间发生了碰撞的场景，该场景下具体的实施方式可以参见上述图1-图4部分关于多个单播传输的HARQ-ACK之间发生了碰撞的场景，在本实施例中，将不对具体过程进行详细的描述。
图5示出根据本公开一实施例的HARQ-ACK的传输方法的流程图。
该实施例的方法可以应用于多个组播传输的HARQ-ACK之间发生了碰撞的场景。
如图5所示，在多个组播传输的HARQ-ACK之间发生了碰撞的场景中，所述方法可以包括：
步骤S21，在多个组播传输的HARQ-ACK之间发生了碰撞时，从所述多个组播传输的HARQ-ACK中选择符合第一预设条件的第一HARQ-ACK；
步骤S22，传输所述第一HARQ-ACK。
在一种可能的实现方式中，所述第一预设条件为以下中的任意一者：HARQ-ACK对应的物理侧链路共享信道PSSCH的优先级最高、HARQ-ACK对应的时域资源的第一个符号的位置最靠前。
根据本公开上述实施例的方法，通过设置第一预设条件，在多个组播传输的HARQ-ACK之间发生了碰撞时，选择符合第一预设条件的HARQ-ACK进行传输，实现了多个组播传输的HARQ-ACK发生碰撞时仍然能够正常传输HARQ-ACK。
其中，如果存在多个HARQ-ACK对应的PSCCH的优先级并列最高的情况时，此时可以基于下列准则之一选择第一HARQ-ACK：
1.选择发生碰撞的承载HARQ-ACK的时频资源或者信道之中第一个symbol最靠前的时频资源或者信道所承载的HARQ-ACK作为所述第一HARQ-ACK；
2.选择发生碰撞的承载HARQ-ACK的时频资源或者信道之中第一个symbol最靠后的时频资源或者信道所承载的HARQ-ACK作为所述第一HARQ-ACK；
3.选择发生碰撞的承载HARQ-ACK的时频资源或者信道之中时域上占用symbol数目最多的时频资源或者信道所承载的HARQ-ACK作为所述第一HARQ-ACK；
4.选择发生碰撞的承载HARQ-ACK的时频资源或者信道之中时域上占用symbol数目最少的时频资源或者信道所承载的HARQ-ACK作为所述第一HARQ-ACK；
5.选择发生碰撞的承载HARQ-ACK的时频资源或者信道之中的任意一个时频资源或者信道所承载的HARQ-ACK作为所述第一HARQ-ACK。
在一种可能的实现方式中，所述方法还包括：
步骤S23，若多个组播传输的HARQ-ACK对应的时域资源的第一个符号的位置相同，则选择多个组播传输的HARQ-ACK中对应的时域持续时长最长或者最短的HARQ-ACK作为所述第一HARQ-ACK、或者选择多个组播传输的HARQ-ACK中的任意一个HARQ-ACK作为所述第一HARQ-ACK。
通过上述实施例的HARQ-ACK的传输方法，在多个组播传输的HARQ-ACK对应的时域资源或者信道的第一个symbol的位置相同，仍然可以实现HARQ-ACK正常传输。
在一种可能的实现方式中，所述方法还包括：
步骤S24，丢弃所述多个组播传输的HARQ-ACK中除了所述第一HARQ-ACK之外的HARQ-ACK。
或者，
步骤S25，将所述多个组播传输的HARQ-ACK中除了所述第一HARQ-ACK之外的HARQ-ACK按照PSSCH的优先级由高到低依次推迟到下一个可传输机会进行传输。
或者，
步骤S26，将所述多个组播传输的HARQ-ACK中除了所述第一HARQ-ACK之外的HARQ-ACK按照时域资源的第一个符号的位置由前到后依次推迟到下一个可传输机会进行传输。
在一种可能的实现方式中，所述方法还包括：
步骤S27，在多个组播传输的HARQ-ACK之间发生了碰撞时，将多个HARQ-ACK以及每个HARQ-ACK对应的目的地址复用到物理上行链路控制信道PUCCH进行传输。
通过上述实施方式的HARQ-ACK的传输方法，在多个组播传输的HARQ-ACK之间发生了碰撞时，可以实现所有HARQ-ACK正常传输。
在一种可能的实现方式中，本公开还提供了一种混合自动重传请求确认HARQ-ACK的传输方法，所述方法应用于用户设备UE。
该实施例的方法应用于单播传输的HARQ-ACK和组播传输的HARQ-ACK之间发生了碰撞的场景。
图6示出根据本公开一实施例的HARQ-ACK的传输方法的流程图。
如图6所示，所述方法可以包括：
步骤S31，在单播传输的HARQ-ACK和组播传输的HARQ-ACK之间发生了碰撞时，从单播传输的HARQ-ACK和组播传输的HARQ-ACK中选择对应的传输的优先级最高的HARQ-ACK进行传输。
在一种可能的实现方式中，所述方法还可以包括：
步骤S32，丢弃对应的传输的优先级低的HARQ-ACK。
或者
步骤S33，将对应的传输的优先级低的HARQ-ACK推迟到下一个可传输机会进行传输。
在一种可能的实现方式中，传输的优先级可以是预先设置的，例如可以预先设置单播的优先级大于组播的优先级，也就是说，单播传输的优先级比组播传输的优先级高。这样，在UE的侧链路上的单播传输的HARQ-ACK和组播传输的HARQ-ACK之间发生了碰撞时，直接传输单播传输的HARQ-ACK，丢弃组播传输的HARQ-ACK，或者，将组播传输的HARQ-ACK推迟到下一个可传输机会进行传输。
在另一种可能的实现方式中，也可以预先设置单播的优先级小于组播的优先级，也就是说，单播传输的优先级比组播传输的优先级低。这样，在UE的侧链路上的单播传输的HARQ-ACK和组播传输的HARQ-ACK之间发生了碰撞时，直接传输组播传输的HARQ-ACK，丢弃单播传输的HARQ-ACK，或者，将单播传输的HARQ-ACK推迟到下一个可传输机会进行传输。
通过上述实施例的HARQ-ACK的传输方法，在单播传输的HARQ-ACK和组播传输的HARQ-ACK之间发生了碰撞时，不需要比较HARQ-ACK对应的PSSCH的优先级，就可以实现HARQ-ACK的正常传输。
在另一种可能的实现方式中，所述方法还可以包括：
步骤S34，在单播传输的HARQ-ACK和组播传输的HARQ-ACK之间发生了碰撞时，从单播传输的HARQ-ACK和组播传输的HARQ-ACK中选择对应的PSSCH的优先级最高的HARQ-ACK进行传输；
步骤S35，将对应的PSSCH的优先级低的HARQ-ACK推迟到下一个可传输机会进行传输。
其中，从单播传输的HARQ-ACK和组播传输的HARQ-ACK中选择对应的PSSCH的优先级最高的HARQ-ACK进行传输，仍然可以通过HARQ-ACK对应的PSSCH的PPPP确定优先级的高低，具体过程不再赘述。
在一种可能的实现方式中，所述方法还可以包括：
丢弃对应的PSSCH的优先级低的HARQ-ACK。
在一种可能的实现方式中，本公开还提供了一种混合自动重传请求确认HARQ-ACK的传输方法，所述方法应用于用户设备UE。

其中，所述第一预设条件为以下中的任意一者：HARQ-ACK对应的PSSCH的优先级最高、HARQ-ACK对应的时域资源的第一个符号的位置最靠前。

在一种可能的实现方式中，本公开还提供了一种混合自动重传请求确认HARQ-ACK的传输方法，所述方法应用于用户设备UE。
该实施例的方法应用于单播传输的HARQ-ACK和多个组播传输的HARQ-ACK之间发生了碰撞的场景。
图8示出根据本公开一实施例的HARQ-ACK的传输方法的流程图。如图8所示，在单播传输的HARQ-ACK和多个组播传输的HARQ-ACK之间发生了碰撞的场景中，所述方法可以包括：
步骤S51，在单播传输的HARQ-ACK以及多个组播传输的HARQ-ACK之间发生了碰撞时，从所述多个组播传输的HARQ-ACK中选择符合第一预设条件的第一HARQ-ACK；

在一种可能的实现方式中，所述第一预设条件为以下中的任意一者：HARQ-ACK对应的PSSCH的优先级最高、HARQ-ACK对应的时域资源的第一个符号的位置最靠前。
其中，步骤S51中的，从所述多个组播传输的HARQ-ACK中选择符合第一预设条件的第一HARQ-ACK的具体过程，可以参见上文中多个组播传输的HARQ-ACK之间发生了碰撞的场景中的方式(步骤S21-S27)，不再赘述。

通过上述实施例的HARQ-ACK的传输方法，在单播传输的HARQ-ACK和多个组播传输的HARQ-ACK之间发生了碰撞的场景中，可以实现HARQ-ACK的正常传输。
在一种可能的实现方式中，本公开还提供了一种混合自动重传请求确认HARQ-ACK的传输方法，所述方法应用于用户设备UE。
该实施例的方法应用于单播传输的HARQ-ACK和CSI反馈之间发生了碰撞，或者，组播传输的HARQ-ACK和CSI反馈之间发生了碰撞的场景。
图9示出根据本公开一实施例的HARQ-ACK的传输方法的流程图。如图9所示，在单播传输的HARQ-ACK和CSI反馈之间发生了碰撞的场景中，或者，组播传输的HARQ-ACK和CSI反馈之间发生了碰撞的场景中，所述方法可以包括：
步骤S61，在HARQ-ACK与信道状态信息CSI反馈之间发生了碰撞时，根据第二预设条件选择HARQ-ACK或者CSI反馈中的一者进行传输；PSFCH与CSI反馈之间发生了碰撞是指PSFCH与承载CSI反馈的信道在时间上发生了至少部分重叠；
其中，所述HARQ-ACK为单播传输的HARQ-ACK或者组播传输的HARQ-ACK。
其中，所述第二预设条件为以下中的任意一者：
HARQ-ACK对应的PSSCH的优先级与优先级阈值的大小关系、HARQ-ACK对应的时域资源或者 信道的第一个符号的位置与CSI反馈对应的时域资源或者信道的第一个符号的位置、预定义的HARQ-ACK与CSI反馈的优先级关系。
通过上述实施例的HARQ-ACK的传输方法，在单播传输或者组播传输的HARQ-ACK和CSI反馈之间发生了碰撞的场景中，可以实现HARQ-ACK的正常传输。
在一种可能的实现方式中，所述方法还可以包括，丢弃未被传输的HARQ-ACK或者CSI反馈。举例来说，若根据第二预设条件选择HARQ-ACK进行传输，则丢弃CSI反馈；若根据第二预设条件选择CSI反馈进行传输，则丢弃HARQ-ACK。
其中，根据不同的分类方式，CSI反馈可以是单播传输或者组播传输的CSI反馈，CSI反馈可以是周期或者非周期的或者是半持续的(semi-persistent)，本公开不对CSI反馈的类型进行限定。此外，承载CSI反馈的信道可以是PSSCH或者PSCCH或者PSFCH或者PUCCH或者PUSCH，本公开不对承载CSI反馈的信道类型进行限定。CSI反馈可以包含以下参数中的至少一种：RI、PMI、CQI(Channel Quality Indicator，信道质量指示)、RSRP(Reference Signal Receiving Power，参考信号接收功率)、RSRQ(Reference Signal Receiving Quality，参考信号接收质量)、L1-SINR(Layer1-Signal to Interference plus Noise Ratio，层1信干噪比)、L1-RSRQ(Layer1-Reference Signal Receiving Quality，层1参考信号接收质量)、L1-RSRP(Layer1-Reference Signal Receiving Power，层1参考信号接收功率)、LI(Layer indicator，层指示)、SRI(Sounding reference signal indicator,探测参考信号指示)、CRI(CSI-RS resource indicator，信道状态信息参考信号资源指示)、SSBRI(Synchronization Signal Block resource indicator,同步信号块资源指示)。上述参数可以是基于侧链路信道的测量，也可以是基于Uu链路的信道的测量。
其中，发生了碰撞可以是承载HARQ-ACK的时频资源或者信道与承载CSI反馈的时频资源或者信道在时间上发生了重叠或者部分重叠，或者可以是承载HARQ-ACK的时频资源或者信道与承载CSI反馈的时频资源或者信道在时间和频域上发生了重叠或者部分重叠。
在一个示例中，以所述第二预设条件为HARQ-ACK对应的PSSCH的优先级与优先级阈值的大小关系为例对该方法进行说明。其中，优先级阈值可以由基站通过高层信令(如RRC信令)或者MAC-CE(MAC Control Element，MAC控制单元)或者DCI(Downlink Control Information，下行链路控制信息)来指示。
如图9所示，步骤S61中的，根据第二预设条件选择HARQ-ACK或者CSI反馈中的一者进行传输，可以包括：
步骤S611，当HARQ-ACK对应的PSSCH的优先级不低于优先级阈值时，选择HARQ-ACK进行传输；
步骤S612，当HARQ-ACK对应的PSSCH的优先级低于优先级阈值时，选择CSI反馈进行传输。
在选择HARQ-ACK进行传输，可以丢弃CSI反馈，在选择CSI反馈进行传输时，可以丢弃HARQ-ACK。举例来说，在单播传输的HARQ-ACK以及CSI反馈之间发生了碰撞时，当单播传输的HARQ-ACK对应的PSSCH的优先级不低于优先级阈值，选择单播传输的HARQ-ACK进行传输。当单播传输的HARQ-ACK对应的PSSCH的优先级低于优先级阈值，选择CSI反馈进行传输。该示例同样适用于组播传输的HARQ-ACK与CSI反馈之间发生了碰撞的场景。
在一个示例中，以所述第二预设条件为预定义的HARQ-ACK与CSI反馈的优先级关系为例对该方 法进行说明。
如图9所示，步骤S61中的，根据第二预设条件选择HARQ-ACK或者CSI反馈中的一者进行传输，可以包括：
步骤S613，若预定义的HARQ-ACK的优先级高于CSI反馈的优先级，则选择HARQ-ACK进行传输；
步骤S614，若预定义的HARQ-ACK的优先级低于CSI反馈的优先级，则选择CSI反馈进行传输。在选择HARQ-ACK进行传输，可以丢弃CSI反馈，在选择CSI反馈进行传输时，可以丢弃HARQ-ACK。
比如，预定义单播传输的HARQ-ACK的优先级高于CSI反馈的优先级。在单播传输的HARQ-ACK以及CSI反馈之间发生了碰撞时，选择单播传输的HARQ-ACK进行传输。
再比如，预定义单播传输的HARQ-ACK的优先级低于CSI反馈的优先级。在单播传输的HARQ-ACK以及CSI反馈之间发生了碰撞时，选择单播传输的CSI反馈进行传输。
以上示例同样适用于组播传输的HARQ-ACK与CSI反馈之间发生了碰撞的场景。
在一个示例中，以所述第二预设条件为HARQ-ACK对应的时域资源或者信道的第一个符号的位置与CSI反馈对应的时域资源或者信道的第一个符号的位置为例对该方法进行说明。

步骤S615，选择对应的时域资源或者信道的第一个符号的位置最靠前的HARQ-ACK或者CSI反馈进行传输。
在选择HARQ-ACK进行传输，可以丢弃CSI反馈，在选择CSI反馈进行传输时，可以丢弃HARQ-ACK。
举例来说，当单播传输的HARQ-ACK以及CSI反馈之间发生了碰撞时，UE可以确定每个HARQ-ACK对应的时域资源或者信道的第一个symbol的位置与CSI反馈对应的时域资源或者信道的第一个symbol的位置，比较HARQ-ACK对应的时域资源或者信道的第一个symbol的位置与CSI反馈对应的时域资源或者信道的第一个symbol的位置的关系，如果HARQ-ACK对应的时域资源或者信道的第一个symbol的位置靠前，则传输HARQ-ACK至相应的UE或者基站、丢弃CSI反馈，如果CSI反馈对应的时域资源或者信道的第一个symbol的位置靠前，则传输CSI反馈至相应的UE或者基站、丢弃HARQ-ACK。
在一种可能的实现方式中，若HARQ-ACK对应的时域资源或者信道的第一个symbol的位置与CSI反馈对应的时域资源或者信道的第一个symbol的位置相同，则选择对应的时域持续时长最长或者最短的HARQ-ACK或者CSI反馈进行传输。举例来说，若HARQ-ACK对应的时域资源或者信道的第一个symbol的位置与CSI反馈对应的时域资源或者信道的第一个symbol的位置相同，可以比较HARQ-ACK对应的时域持续时长和CSI反馈对应的时域持续时长，选择对应的时域持续时长最长或者最短的HARQ-ACK或者CSI反馈进行传输。
通过上述实施例的HARQ-ACK的传输方法，在HARQ-ACK与CSI反馈发生碰撞时，在HARQ-ACK对应的时域资源或者信道的第一个symbol的位置与CSI反馈对应的时域资源或者信道的第一个symbol的位置相同，仍然可以实现正常传输。
在一种可能的实现方式中，本公开还提供了一种混合自动重传请求确认HARQ-ACK的传输方法， 所述方法应用于用户设备UE。
该实施例的方法应用于单播传输的HARQ-ACK和SR(Scheduling Request，调度请求)之间发生了碰撞，或者，组播传输的HARQ-ACK和SR之间发生了碰撞的场景。

在一种可能的实现方式中，所述方法还可以包括，丢弃未被传输的HARQ-ACK或者SR。举例来说，若根据第二预设条件选择HARQ-ACK进行传输，则丢弃SR；若根据第二预设条件选择SR进行传输，则丢弃HARQ-ACK。
在一种可能的实现方式中，所述第三预设条件为以下中的任意一者：
HARQ-ACK对应的PSSCH的优先级与优先级阈值的大小关系、HARQ-ACK对应的时域资源或者信道的第一个符号的位置与SR对应的时域资源或者信道的第一个符号的位置、预定义的HARQ-ACK与SR的优先级关系。
通过上述实施例的HARQ-ACK的传输方法，在单播传输或者组播传输的HARQ-ACK和SR之间发生了碰撞的场景中，可以实现HARQ-ACK的正常传输。其中，发生了碰撞可以是承载HARQ-ACK的时频资源或者信道与承载SR的时频资源或者信道在时间上发生了重叠或者部分重叠，或者可以是承载HARQ-ACK的时频资源或者信道与承载SR的时频资源或者信道在时间和频域上发生了重叠或者部分重叠。
其中，优先级阈值可以由基站通过高层信令(如RRC信令)或者MAC-CE(MAC Control Element，MAC控制单元)或者DCI(Downlink Control Information，下行链路控制信息)来指示。
在一个示例中，以所述第三预设条件为HARQ-ACK对应的PSSCH的优先级与优先级阈值的大小关系为例对该方法进行说明。

步骤S712，当HARQ-ACK对应的PSSCH的优先级低于优先级阈值时，选择SR进行传输。
在选择HARQ-ACK进行传输，可以丢弃SR，在选择SR进行传输时，可以丢弃HARQ-ACK。
举例来说，在单播传输的HARQ-ACK以及SR之间发生了碰撞时，当单播传输的HARQ-ACK对应的PSSCH的优先级不低于优先级阈值，选择单播传输的HARQ-ACK进行传输。当单播传输的 HARQ-ACK对应的PSSCH的优先级低于优先级阈值，选择SR进行传输。该示例同样适用于组播传输的HARQ-ACK与SR之间发生了碰撞的场景。
在一个示例中，以所述第三预设条件为：预定义的HARQ-ACK与SR的优先级关系为例对该方法进行说明。
如图10所示，步骤S71中的，根据第二预设条件选择HARQ-ACK或者SR中的一者进行传输，包括：
步骤S713，若预定义的HARQ-ACK的优先级高于SR的优先级，则选择HARQ-ACK进行传输；
步骤S714，若预定义的HARQ-ACK的优先级低于SR的优先级，则选择SR进行传输。
在选择HARQ-ACK进行传输，可以丢弃SR，在选择SR进行传输时，可以丢弃HARQ-ACK。比如，预定义单播传输的HARQ-ACK的优先级高于SR的优先级。在单播传输的HARQ-ACK以及SR之间发生了碰撞时，选择单播传输的HARQ-ACK进行传输。
再比如，预定义单播传输的HARQ-ACK的优先级低于SR的优先级。在单播传输的HARQ-ACK以及SR之间发生了碰撞时，选择SR进行传输。
以上示例同样适用于组播传输的HARQ-ACK与SR之间发生了碰撞的场景。

如图10所示，步骤S71中的，根据第二预设条件选择HARQ-ACK或者SR中的一者进行传输，可以包括：
步骤S715，选择对应的时域资源或者信道的第一个符号的位置最靠前的HARQ-ACK或者SR进行传输。
在选择HARQ-ACK进行传输，可以丢弃SR，在选择SR进行传输时，可以丢弃HARQ-ACK。
举例来说，当单播传输的HARQ-ACK以及SR之间发生了碰撞时，UE可以确定每个HARQ-ACK对应的时域资源或者信道的第一个symbol的位置与SR对应的时域资源或者信道的第一个symbol的位置，比较HARQ-ACK对应的时域资源或者信道的第一个symbol的位置与SR对应的时域资源或者信道的第一个symbol的位置的关系，如果HARQ-ACK对应的时域资源或者信道的第一个symbol的位置靠前，则传输HARQ-ACK至相应的UE或者基站、丢弃SR，如果SR对应的时域资源或者信道的第一个symbol的位置靠前，则传输SR至相应的UE或者基站、丢弃HARQ-ACK。
在一种可能的实现方式中，若HARQ-ACK对应的时域资源或者信道的第一个symbol的位置与SR对应的时域资源或者信道的第一个symbol的位置相同，则选择对应的时域持续时长最长或者最短的HARQ-ACK或者SR进行传输。举例来说，若HARQ-ACK对应的时域资源或者信道的第一个symbol的位置与SR对应的时域资源或者信道的第一个symbol的位置相同，可以比较HARQ-ACK对应的时域持续时长和SR对应的时域持续时长，选择对应的时域持续时长最长或者最短的HARQ-ACK或者SR进行传输。

在一种可能的实现方式中，本公开还提供了一种混合自动重传请求确认HARQ-ACK的传输方法， 所述方法应用于用户设备UE，该实施例的方法应用于多个单播传输的HARQ-ACK之间发生了碰撞，或者，多个组播传输的HARQ-ACK之间发生了碰撞，或者，单播传输的HARQ-ACK与组播传输的HARQ-ACK发生碰撞的场景。下文中将以单播传输的HARQ-ACK之间发生了碰撞的场景为例进行介绍。图11示出根据本公开一实施例的HARQ-ACK的传输方法的流程图。如图11所示，所述方法可以包括：
步骤S81，在多个单播传输的HARQ-ACK之间发生了碰撞时，将多个HARQ-ACK复用在时频资源或者信道上进行传输。
其中，将多个HARQ-ACK复用在时频资源或者信道上进行传输可以包括：
步骤S811，确定每个HARQ-ACK对应的序列；
步骤S812，选择时频资源或信道；
步骤S813，针对每个HARQ-ACK，在选择的时频资源或者信道在时域和/或频域上乘以该HARQ-ACK对应的序列得到第一时频资源或者信道，将该HARQ-ACK在所述第一时频资源或者信道进行传输。
其中，所述序列可以是OCC(orthogonal covering code，正交覆盖序列)序列，或者，CS(cyclic shift,循环移位)序列。在选择的时频资源或者信道在时域或者频域上乘以该HARQ-ACK对应的序列，可以为在选择的时频资源或者信道在时域上乘以该HARQ-ACK对应的OCC序列、或者在选择的时频资源或者信道在频域上乘以该HARQ-ACK对应的CS序列。根据上述实施例的方法，可以将发生碰撞的承载HARQ-ACK的时频资源或者信道在时域上通过乘以使用不同的OCC序列来做区分，或者将这些发生碰撞的承载HARQ-ACK的时频资源或者信道在频域上通过乘以使用不同的CS序列来做区分，或者将这些发生碰撞的承载HARQ-ACK的时频资源或者信道在时域上通过乘以使用不同的OCC(orthogonal covering code，正交覆盖序列)序列同时在频域上通过乘以使用不同的CS(cyclic shift,循环移位)序列来做区分。
当单播传输的HARQ-ACK之间发生碰撞时，可以将这些单播传输的HARQ-ACK复用在一个特定的时频资源或者信道上。其中，该特定的时频资源或者信道可以是PSSCH或者PSCCH或者PSFCH或者PUCCH或者PUSCH，其可以由基站通过高层信令配置或者通过预定义的规则来确定。
其中，选择承载发生碰撞的HARQ-ACK的时频资源或者信道的预定义规则可以是下列之一：
1.选择发生碰撞的承载HARQ-ACK的时频资源或者信道之中第一个symbol最靠前的时频资源或者信道；
2.选择发生碰撞的承载HARQ-ACK的时频资源或者信道之中时域上占用symbol数目最多的时频资源或者信道。
3.选择发生碰撞的承载HARQ-ACK的时频资源或者信道之中的任意一个时频资源或者信道；

上述实施例同样可以适用于单播传输的HARQ-ACK与组播传输的HARQ-ACK发生碰撞的情况，或者组播传输的HARQ-ACK与组播传输的HARQ-ACK发生碰撞的情况。不再赘述。
通过上述实施方式的HARQ-ACK的传输方法，在多个HARQ-ACK之间发生了碰撞时，可以实现所有HARQ-ACK正常传输。
在一种可能的实现方式中，所述方法还可以包括：UE向基站汇报以下信息中的至少一个，UE在侧链路上能同时支持的单播传输的最大数目、在侧链路上能同时支持的组播传输的最大数目、在侧链路上能同时支持的单播传输与组播传输之和的最大数目、在侧链路上能支持的所有单播传输的HARQ进程的最大数目、在侧链路上能支持的所有组播传输的HARQ进程的最大数目、在侧链路上能支持的所有单播传输与所有组播传输的HARQ进程之和的最大数目、在侧链路上能支持的单播传输的HARQ进程与UE在Uu链路上能支持的HARQ进程之和的最大数目、在侧链路上能支持的组播传输的HARQ进程与UE在Uu链路上能支持的HARQ进程之和的最大数目、UE是否有能力成为侧链路传输中组播传输中的组头领(group header)、UE是否有能力成为侧链路传输中的组头领。
在一种可能的实现方式中，UE可以通过高层信令向基站汇报。
这样，基站在接收到UE汇报的上述内容后，可以进行相应的配置。例如，基站在接收到UE向基站汇报的UE在侧链路上能同时支持的单播传输的最大数目时，基站可以通过高层信令配置UE在侧链路上的单播传输的数目为该最大数目。根据同样的原理，基站可以通过高层信令配置UE在侧链路上组播传输的数目、在侧链路上单播传输与组播传输之和的数目、在侧链路上单播传输的HARQ进程的数目、在侧链路上组播传输的HARQ进程的数目，在侧链路上单播传输与组播传输的HARQ进程之和的数目、在侧链路上单播传输的HARQ进程与UE在Uu链路上的HARQ进程之和的数目、在侧链路上组播传输的HARQ进程与UE在Uu链路上的HARQ进程之和的数目。

在一种可能的实现方式中，所述方法还可以包括：基站通过高层信令或者MAC-CE或者DCI来激活或者去激活组播传输的HARQ-ACK的功能、基站通过高层信令或者MAC-CE或者DCI来激活或者去激活单播传输的HARQ-ACK的功能、基站通过高层信令或者MAC-CE或者DCI来激活或者去激活广播传输的HARQ-ACK的功能。在一种可能的实现方式中，所述方法还可以包括：基站通过高层信令或者MAC-CE或者DCI来指示组播是采用只有NACK的反馈方式还是同时有ACK和NACK的反馈方式。举例来说，基站可以通过1bit的RRC(Radio Resource Control，无线资源控制)信令来指示组播是采用只有NACK的反馈方式还是同时有ACK和NACK的反馈方式，例如，0可以表示采用只有NACK的反馈 方式，1可以表示采用同时有ACK和NACK的反馈方式。
在一种可能的实现方式中，所述方法还可以包括：基站通过高层信令或者MAC-CE或者DCI来指示当前的传输是单播还是组播、基站通过高层信令或者MAC-CE或者DCI来指示当前的传输是单播还是广播、基站通过高层信令或者MAC-CE或者DCI来指示当前的传输是组播还是广播、基站通过高层信令或者MAC-CE或者DCI来指示当前的传输是单播、组播还是广播。其中，当前的传输可以指的是PSSCH传输或者PSCCH传输。
