具体实施方式
一、相关技术一：sidelink HARQ-ACK在Uu传输。
(1)关于NR车联万物(Vehicle-to-Everything，V2X)模式1(mode-1)HARQ-ACK传输方法：参见图1，图中示意NR V2X mode-1 sidelink HARQ-ACK传输，具体步骤如下：
步骤1：发送端(transmitter)发送调度请求(Scheduling Request，SR)以及sidelink缓存状态报告(Buffer Status Report，BSR)给基站；
步骤2：基站(gNB)发送DCI给transmitter进行资源分配；
步骤3：transmitter根据收到的基站下发的sidelink grant，在相应的资源发送SCI和数据(data)；
步骤4：接收端(receiver)盲检直通链路控制信息(Sidelink Control Information，SCI)，接收数据，并发送SFCI给transmitter；
步骤5：transmitter发送sidelink HARQ-ACK给基站，向基站申请重传资源；
步骤6：基站下发DCI给transmitter调度重传。
(2)长期演进(Long Term Evolution，LTE)-V2X中的数据包的近场通信优先级(ProSe Per-Packet Priority，PPPP)：
LTE V2X PPPP共8种，由应用层生成，由终端报告给基站优先级信息(priority information)来反应PPPP，基站可以通过priority information推导出相应数据包(packet)的延迟预算(delay budget)；
LTE SCI format 1中包含3比特(bit)的优先级信息，用于终端感应(sensing)等目的。
NR将复用PPPP的思想，与QoS流(flow)的设计，产生例如PFI标识(PC5 QoS Flow Identifiers)，用于表征业务优先级与QoS要求(requirement)。
二、相关技术二：Sidelink HARQ-ACK在sidelink/PC5传输。
通过了至少支持一种基于序列的物理直通链路反馈信道(Physical  Sidelink Feedback Channel，PSFCH)格式(format)，其他类型的PSFCH format需要进一步研究(For Further Study，FFS)。
PSFCH资源的确定方式：
PSFCH和关联的PSSCH之间的时间间隔(time gap)是预配置的((pre-)configuration)的。

在一些实施方式中，所述配置的PSFCH资源池或资源集合是通过协议预定义的方式，或者网络侧通过高层信令配置。
本公开实施例中，可以保证不同业务的SFCI的时延、可靠性需求得到满足。
下面结合示例一、示例二和示例三介绍本公开实施例的HARQ-ACK的发送方法、PSFCH资源确定的方法。
示例一：关于多业务优先级sidelink HARQ-ACK的发送方法：
通过预定义的方式，或者基站通过高层信令配置的方式，配置第一标识 和HARQ codebook之间的映射关系。
可选地，所述第一标识包括以下一项或多项：PFI标识(PC5 QoS Flow Identifiers)、PPPP等，用于表征所述HARQ codebook对应的业务/数据包的QoS要求，具体包括如下方式：
-通过预定义的方式，或者基站通过高层信令配置的方式，配置所述第一标识门限值，当数据包对应的第一标识低于或高于第一门限值时，使用第一HARQ codebook，当数据包对应的第一标识高于或低于第二门限值时，使用第二HARQ codebook。
-所述第一HARQ codebook或第二HARQ codebook包括以下一项或多项：slot-based HARQ codebook以及相应的HARQ-ACK related PUCCH configuration、sub-slot based HARQ codebook方式以及相应的HARQ-ACK related PUCCH configuration。
-通过预定义的方式，或者基站通过高层信令配置的方式，配置所述第一标识和HARQ codebook的映射表格，参见表1。
终端根据数据包对应的第一标识，确定所使用的HARQ codebook以及相应的PUCCH configuration。
示例二：关于多业务优先级sidelink HARQ-ACK的发送方法：
基站根据终端上报的优先级、PFI标识(PC5QoS Flow Identifiers)等相关信息，决定sidelink HARQ-ACK所使用的码本，并通过调度sidelink数据的物理层下行控制信息指示终端所使用的HARQ codebook。具体实现方式如下：
-例如，有至少两种调度sidelink数据的DCI格式：DCI format 5A和DCI format 5B，当使用DCI format 5A调度sidelink数据时，使用第一HARQ codebook，当使用DCI format 5B调度sidelink数据时，使用第二HARQ codebook；
-例如，用于加扰调度sidelink数据的DCI的RNTI有至少两种，当使用RNTI 1加扰调度sidelink数据的DCI时，使用第一HARQ codebook；当使用RNTI 2加扰调度sidelink数据的DCI时，使用第二HARQ codebook；
-例如，在调度sidelink数据的DCI中增加HARQ codebook指示域，用于指示所述DCI调度的sidelink数据对应的HARQ-ACK使用第一HARQ codebook或者第二HARQ codebook
-所述第一HARQ codebook或第二HARQ codebook包括以下一项或多项：slot-based HARQ codebook以及相应的HARQ-ACK related PUCCH configuration、sub-slot based HARQ codebook方式以及相应的HARQ-ACK related PUCCH configuration。
-UE根据基站的指示确定所使用的HARQ codebook以及相应的PUCCH configuration信息
在示例一和示例二中，通过配置PC5QoS Flow Identifier与sidelink HARQ codebook的映射关系，或者通过引入不同的DCI format、RNTI等用于调度sidelink数据，来保证不同业务的sidelink HARQ-ACK的时延、可靠性得到满足。
示例三：关于基于第一信息的PSFCH资源确定方式：
所述第一信息包含在直通链路控制信息(Sidelink Control Information，SCI)中，用于指示其调度的PSSCH上的数据包的优先级；
-通过预定义的方式，或者基站/发送端通过高层信令配置的方式，为接收端配置多个PSFCH资源池/资源集合，接收端根据第一信息，从配置的多个资源池中确定其中一个PSFCH资源池/资源集合；或者
-通过预定义的方式，或者基站/发送端通过高层信令配置的方式，为接收端配置PSFCH资源池/资源集合，接收端根据第一信息，从配置的资源池/资源集合中确定PSFCH的格式；或者
-通过预定义的方式，或者基站/发送端通过高层信令配置的方式，为接收端配置PSFCH资源池/资源集合，接收端根据第一信息，从配置的资源池中确定PSFCH的频域/码域资源。
在示例三中，通过利用优先级隐式确定PSFCH的资源/PSFCH格式的方式，来保证不同业务的SFCI的时延、可靠性需求得到满足。
