具体实施方式
为了更好的理解本公开实施例公开的一种混合自动重传请求反馈方法，下面首先对本公开实施例适用的通信***进行描述。
请参见图1，图1为本公开实施例提供的一种通信***的架构示意图。该通信***可包括但不限于一个网络设备和一个终端设备，图1所示的设备数量和形态仅用于举例并不构成对本公开实施例的限定，实际应用中可以包括两个或两个以上的网络设备，两个或两个以上的终端设备。图1所示的通信***以包括一个网络设备101、一个终端设备102为例。
需要说明的是，本公开实施例的技术方案可以应用于各种通信***。例如：长期演进(long term evolution，LTE)***、第五代(5th generation，5G)移动通信***、5G新空口(new radio，NR)***，或者其他未来的新型移动通信***等。
本公开实施例中的网络设备101是网络侧的一种用于发射或接收信号的实体。例如，网络设备101可以为演进型基站(evolved NodeB，eNB)、传输点(transmission reception point，TRP)、NR***中的下一代基站(next generation NodeB，gNB)、其他未来移动通信***中的基站或无线保真(wireless fidelity，WiFi)***中的接入节点等。本公开的实施例对网络设备所采用的具体技术和具体设备形态不做限定。本公开实施例提供的网络设备可以是由集中单元(central unit，CU)与分布式单元(distributed unit，DU)组成的，其中，CU也可以称为控制单元(control unit)，采用CU-DU的结构可以将网络设备，例如基站的协议层拆分开，部分协议层的功能放在CU集中控制，剩下部分或全部协议层的功能分布在DU中，由CU集中控制DU。
本公开实施例中的终端设备102是用户侧的一种用于接收或发射信号的实体，如手机。终端设备也可以称为终端设备(terminal)、用户设备(user equipment，UE)、移动台(mobile station，MS)、移动终端设备(mobile terminal，MT)等。终端设备可以是具备通信功能的汽车、智能汽车、手机(mobile phone)、穿戴式设备、平板电脑(Pad)、带无线收发功能的电脑、虚拟现实(virtual reality，VR)终端设备、增强现实(augmented reality，AR)终端设备、工业控制(industrial control)中的无线终端设备、无人驾驶(self-driving)中的无线终端设备、远程手术(remote medical surgery)中的无线终端设备、智能电网(smart grid)中的无线终端设备、运输安全(transportation safety)中的无线终端设备、智慧城市(smart city)中的无线终端设备、智慧家庭(smart home)中的无线终端设备等等。本公开的实施例对终端设备所采用的具体技术和具体设备形态不做限定。
上述通信***中，如果终端设备在初始时隙之后延迟了很长时间才向基站传输HARQ-ACK，这种传输HARQ-ACK的方式，不能满足URLLC的传输时延和传输有效性的要求。因此，如何使得终端设备在支持HARQ-ACK反馈延迟的同时，满足URLLC的传输时延和传输有效性的要求是目前亟需解决的技术问题。
本公开实施例中，在需要传输HARQ-ACK的情况下，确定出HARQ-ACK传输所在的初始时隙，并在确定初始时隙上的PUCCH资源无效的情况下，确定出HARQ-ACK的最晚延迟反馈时隙，并通过在初始时隙与最晚延迟反馈时隙之间的任意时隙或者最晚延迟反馈时隙上的有效的PUCCH资源发送HARQ-ACK。由此，在支持延迟反馈HARQ-ACK的同时，保证超高可靠低时延通信URLLC的传输时延和传输有效性。
可以理解的是，本公开实施例描述的通信***是为了更加清楚的说明本公开实施例的技术方案，并不构成对于本公开实施例提供的技术方案的限定，本领域普通技术人员可知，随着***架构的演变和新业务场景的出现，本公开实施例提供的技术方案对于类似的技术问题，同样适用。
下面结合附图对本公开所提供的混合自动重传请求反馈方法及装置进行详细地介绍。
请参见图2a，图2a是本公开实施例提供的一种混合自动重传请求反馈方法的流程示意图。该混合自动重传请求反馈方法可以由图1所示的通信***中的终端设备执行。
如图2a所示，该混合自动重传请求反馈方法可以包括但不限于如下步骤：
步骤201，确定HARQ-ACK传输所在的初始时隙。
在一些实施例中，上述HARQ-ACK传输所在的初始时隙可以是基于网络设备发送的激活指令所确定出的。以HARQ-ACK为SPS PDSCH的HARQ-ACK进行示例性说明，SPS PDSCH的HARQ-ACK传输所在的初始时隙可以是基于网络设备发送的SPS PDSCH的激活指令所确定出的。
其中，激活指令可以为下行控制信息(Downlink Control Information，DCI)信令。
步骤202，响应于确定初始时隙上的第一PUCCH资源无效，确定用于HARQ-ACK传输的最晚延迟反馈时隙。
在一些实施例中，可获取初始时隙上的第一PUCCH资源所对应的符号集合，在确定该符号集合中包含无效符号的情况下，可确定初始时隙上的第一PUCCH资源无效。
在本公开实施例中，如图2b所示，可以通过以下方式确定用于HARQ-ACK传输的最晚延迟反馈时隙：
步骤202a，在确定初始时隙上的第一PUCCH资源无效的情况下，确定HARQ-ACK的最晚延迟反馈时隙偏移值；
步骤202b，根据初始时隙和最晚延迟反馈时隙偏移值，确定HARQ-ACK的最晚延迟反馈时隙。在一些可能的实现方式中，本公开实施例的可用于HARQ-ACK传输的最晚延迟反馈时隙，可以通过通信协议(例如TDRA表、例如可用于HARQ-ACK传输的多个候选位置、例如多个初始时隙K1的最大K1值)确定，也可以通过其他参数(例如初始时隙的最多可延迟次数、SPS PDSCH的传输周期、SPS PDSCH的分组绑定尺寸或者时间窗口的长度)确定，还可以通过网络侧配置确定。在以下的各个实施例中，以根据最晚延迟反馈时隙偏移值确定HARQ-ACK的最晚延迟反馈时隙，作为示例进行说明，并示例性的给出了如何通过通信协议、其他参数等方式来确定HARQ-ACK的最晚延迟反馈时隙。当然，如果采用其他方式确定HARQ-ACK的最晚延迟反馈时隙时，这些通过通信协议、其他参数、网络侧配置的示例也同样适用，只需要针对不同的确定HARQ-ACK的最晚延迟反馈时隙的方式进行相应小修改即可。
在一些实施例中，最晚延迟反馈时隙偏移基于连续时隙，即可将初始时隙和最晚延迟反馈时隙偏移值进行相加，并将相加所得到的值作为HARQ-ACK的最晚延迟反馈时隙。
在另一些实施例中，最晚延迟反馈时隙偏移基于可用时隙，不可将初始时隙和最晚延迟反馈时隙偏移值直接进行相加作为HARQ-ACK的最晚延迟反馈时隙。
步骤203，确定有效的第二PUCCH资源，并通过第二PUCCH资源发送上述HARQ-ACK，其中，第二PUCCH资源所在的时隙为初始时隙之后，且不晚于最晚延迟反馈时隙的时隙。
在本公开的实施例中，都可以从初始时隙开始向后依次寻找并确定有效的第二PUCCH资源。当然，这只是举例说明，可以通过任何方式确定出有效的第二PUCCH资源，本公开实施例并不对此作出限定。
在本公开的实施例中，在需要传输HARQ-ACK的情况下，确定出HARQ-ACK传输所在的初始时隙，并在确定初始时隙上的PUCCH资源无效的情况下，确定出HARQ-ACK的最晚延迟反馈时隙，并通过在初始时隙与最晚延迟反馈时隙之间的任意时隙或者最晚延迟反馈时隙上的有效的PUCCH资源发送HARQ-ACK。由此，在支持延迟反馈HARQ-ACK的同时，保证超高可靠低时延通信URLLC的传输时延和传输有效性。

步骤302，在确定初始时隙上的第一PUCCH资源无效的情况下，根据协议约定确定HARQ-ACK的最晚延迟反馈时隙偏移值。
在一些实施例中，在确定初始时隙上的第一PUCCH资源无效的情况下，网络设备与终端设备之间可事先协议约定HARQ-ACK的最晚延迟反馈时隙偏移值，从而使得终端设备在需要获知HARQ-ACK的最晚延迟反馈时隙偏移值的情况下，可基于协议确定，确定出HARQ-ACK的最晚延迟反馈时隙偏移值。
作为一种示例，协议约定最晚延迟反馈时隙偏移值为固定值，比如为8。需要说明的是，上述仅为示例性说明，最晚延迟反馈时隙偏移值也可以约定为其他值，本公开对此并不做限制。
步骤303，根据初始时隙和最晚延迟反馈时隙偏移值，确定上述HARQ-ACK的最晚延迟反馈时隙。
在一些实施例中，最晚延迟反馈时隙偏移基于连续时隙，即可将初始时隙和最晚延迟反馈时隙偏移值进行相加，并将相加所得到的值作为HARQ-ACK的最晚延迟反馈时隙。
在另一些实施例中，最晚延迟反馈时隙偏移基于可用时隙，不可将初始时隙和最晚延迟反馈时隙偏移值直接进行相加作为HARQ-ACK的最晚延迟反馈时隙。
步骤304，确定有效的第二PUCCH资源，并通过第二PUCCH资源发送上述HARQ-ACK，其中，第二PUCCH资源所在的时隙为初始时隙之后，且不晚于最晚延迟反馈时隙的时隙。
在一些实施例中，上述第二PUCCH资源所在的时隙可以为初始时隙与最晚延迟反馈时隙之间的时隙。
在另一些实施例中，上述第二PUCCH资源所在的时隙可以为最晚延迟反馈时隙。
在本公开的实施例中，在需要延迟发送HARQ-ACK的情况下，结合协议约定，确定出了HARQ-ACK的最晚延迟反馈时隙偏移值，并基于最晚延迟反馈时隙偏移值和HARQ-ACK的初始时隙，确定出了HARQ-ACK的最晚延迟反馈时隙，并在最晚延迟反馈时隙，或者初始时隙与最晚延迟反馈时隙之间的时隙上的有效的PUCCH资源上传输HARQ-ACK。由此，在支持延迟反馈HARQ-ACK的同时，保证超高可靠低时延通信URLLC的传输时延和传输有效性。
需要说明的是，上述的这些可能的实现方式可以单独被执行，也可以结合在一起被执行，本公开实施例并不对此作出限定。

步骤401，确定HARQ-ACK传输所在的初始时隙。
在本公开的实施例中，步骤401可以采用本公开的各实施例中的任一种方式实现，本公开实施例并不对此作出限定，也不再赘述。
步骤402，在确定初始时隙上的第一PUCCH资源无效的情况下，基于协议约定确定HARQ-ACK 的多个候选的最晚延迟反馈时隙偏移值，从多个候选的最晚延迟反馈时隙偏移值中确定最晚延迟反馈时隙偏移值。
在一些实施例中，在确定初始时隙上的第一PUCCH资源无效的情况下，网络设备与终端设备之间可事先协议约定HARQ-ACK的多个候选的最晚延迟反馈时隙偏移值，从而使得终端设备可基于协议确定，确定出HARQ-ACK的多个候选的最晚延迟反馈时隙偏移值。
在一些实施例中，从多个候选的最晚延迟反馈时隙偏移值中确定最晚延迟反馈时隙偏移值的一种可能的实现方式可以为：可接收网络设备发送的指示指令，其中，所述指示指令用于选择并指示上述多个候选的最晚延迟反馈时隙偏移值中的其中一个时隙偏移值，可根据所述指示指令，从多个候选的最晚延迟反馈时隙偏移值中确定出最晚延迟反馈时隙偏移值。比如，可以将指示指令所指示的时隙偏移值作为最晚延迟反馈时隙偏移值。
举例而言，多个候选的最晚延迟反馈时隙偏移值可以为{0,8,16,24,…}，假设指示指令所指示的时隙偏移值为8，则可以确定最晚延迟反馈时隙偏移值为8。
步骤403，根据初始时隙和最晚延迟反馈时隙偏移值，确定HARQ-ACK的最晚延迟反馈时隙。
在一些实施例中，最晚延迟反馈时隙偏移基于连续时隙，即可将初始时隙和最晚延迟反馈时隙偏移值进行相加，并将相加所得到的值作为HARQ-ACK的最晚延迟反馈时隙。
在另一些实施例中，最晚延迟反馈时隙偏移基于可用时隙，不可将初始时隙和最晚延迟反馈时隙偏移值直接进行相加作为HARQ-ACK的最晚延迟反馈时隙。
步骤404，确定有效的第二PUCCH资源，并通过第二PUCCH资源发送上述HARQ-ACK，其中，第二PUCCH资源所在的时隙为初始时隙之后，且不晚于最晚延迟反馈时隙的时隙。

在一些实施例中，在确定初始时隙上的第一PUCCH资源无效的情况下，网络设备与终端设备之间可事先协议约定，并在协议约定中约定时域资源分配TDRA表，该TDRA表每行绑定一些时隙偏移值。从而使得终端设备可基于协议约定，确定TDRA表的行索引，并获取TDRA表中与所述行索引所绑定的时隙偏移值，并将所获取到的时隙偏移值作为HARQ-ACK的最晚延迟反馈时隙偏移值。
举例而言，TDRA表中每一行具有一个或多个时隙偏移值，可以通过协议指示TDRA表格的行索引，从而可以获取TDRA表中与行索引所绑定的时隙偏移值，作为最晚延迟反馈时隙偏移值。

在另一些实施例中，还可以根据预设运算规则，对最大K1值进行运算，并将运算所得到的值作为最晚延迟反馈时隙偏移值。
在一些实施例中，上述预设运算规则可以为：将最大K1值加上指定的时隙间隔值，例如，指定的时隙间隔值为2，假设最大K1值为16，此时，可将最大K1值加上指定的时隙间隔值所得到的时隙值18，作为HARQ-ACK的最晚延迟反馈时隙偏移值。

步骤704，根据初始时隙和最晚延迟反馈时隙偏移值，确定HARQ-ACK的最晚延迟反馈时隙。
在一些实施例中，最晚延迟反馈时隙偏移基于连续时隙，即可将初始时隙和最晚延迟反馈时隙偏移值进行相加，并将相加所得到的值作为HARQ-ACK的最晚延迟反馈时隙。
在另一些实施例中，最晚延迟反馈时隙偏移基于可用时隙，不可将初始时隙和最晚延迟反馈时隙偏移值直接进行相加作为HARQ-ACK的最晚延迟反馈时隙。
步骤705，确定有效的第二PUCCH资源，并通过第二PUCCH资源发送上述HARQ-ACK，其中，第二PUCCH资源所在的时隙为初始时隙之后，且不晚于最晚延迟反馈时隙的时隙。
在一些实施例中，上述第二PUCCH资源所在的时隙可以为初始时隙与最晚延迟反馈时隙之间的时隙。

步骤802，在确定初始时隙上的第一PUCCH资源无效的情况下，确定初始时隙最多可延迟的次数。
步骤803，根据上述次数，确定最晚延迟反馈时隙偏移值。
在一些实施例中，在确定初始时隙上的第一PUCCH资源无效的情况下，可以定义初始时隙最多向后可延迟的次数，根据上述最多向后可延迟的次数，确定最晚延迟反馈时隙偏移值。例如，可以将上述最多向后可延迟的次数，作为最晚延迟反馈时隙偏移值。其中，最多可延迟次数，可以是指初始时隙最多可以被向后偏移的次数，而每次偏移的单位可以为symbol、slot、subframe中的任一项。
步骤804，根据初始时隙、半静态配置的时分双工(Time Division Duplexing，TDD)结构和最晚延迟反馈时隙偏移值，确定HARQ-ACK的最晚延迟反馈时隙。
在一些实施例中，可以根据初始时隙、半静态配置的TDD结构和最晚延迟反馈时隙偏移值，确定HARQ-ACK的最晚延迟反馈时隙。
举例而言，TDD结构为DSUUUDDSUU结构，其中，D为下行时隙，S为特殊时隙，U为上行时隙。假设定义初始时隙最多可延迟的次数M为3次，假设初始时隙为第一个上行符号所在的时隙，并尝试延迟3次上行符号的时隙(即可用时隙)，到第四个上行符号所在的时隙上截止(即跳过初始时隙后的不可用时隙)，可根据第四个上行符号所在的时隙与第一个上行符号所在的时隙之间的时隙偏移值，确定出HARQ-ACK的最晚延迟反馈时隙。
步骤805，确定有效的第二PUCCH资源，并通过第二PUCCH资源发送上述HARQ-ACK，其中，第二PUCCH资源所在的时隙为初始时隙之后，且不晚于最晚延迟反馈时隙的时隙。
在一些实施例中，上述第二PUCCH资源所在的时隙可以为初始时隙与最晚延迟反馈时隙之间的时隙。
在另一些实施例中，上述第二PUCCH资源所在的时隙可以为最晚延迟反馈时隙。
在本公开的实施例中，在需要确定出HARQ-ACK所对应的最晚延迟反馈时隙偏移值时，可确定初始时隙最多可延迟的次数，并根据初始时隙最多可支持的次数，确定最晚延迟反馈时隙偏移值。由此，即使网络设备未指示HARQ-ACK的最晚延迟反馈时隙偏移值，终端设备也可基于固定规则确定出HARQ-ACK的最晚延迟反馈时隙偏移值。
在本公开的实施例中，在需要延迟发送HARQ-ACK的情况下，确定初始时隙最多可延迟的次数，并根据初始时隙最多可支持的次数确定最晚延迟反馈时隙偏移值，根据初始时隙、半静态配置的TDD结构和最晚延迟反馈时隙偏移值，确定出HARQ-ACK的最晚延迟反馈时隙，并在最晚延迟反馈时隙，或者初始时隙与最晚延迟反馈时隙之间的时隙上的有效的PUCCH资源上传输HARQ-ACK。由此，在支持延迟反馈HARQ-ACK的同时，保证超高可靠低时延通信URLLC的传输时延和传输有效性。

步骤902，在确定初始时隙上的第一PUCCH资源无效的情况下，根据SPS PDSCH的传输周期，确定HARQ-ACK的最晚延迟反馈时隙偏移值。
在一些实施例中，可获取与SPS PDSCH的传输周期对应的时隙偏移值，并将所获取到的时隙偏移值作为HARQ-ACK的最晚延迟反馈时隙偏移值。
