具体实施方式
为了能够更加详尽地了解本申请实施例的特点和技术内容，下面结合附图对本申请实施例的实现进行详细阐述，所附附图仅供参考说明之用，并非用来限定本申请实施例。
在对本申请实施例提供的混合自动重传请求进程信息的方法进行详细说明之前，先对本申请实施例涉及的相关信息进行简要说明。
D2D通信是基于SL传输技术，与传统的蜂窝系统中通信数据通过基站接收或者发送的方式不同，车联网系统采用D2D通信的方式(即设备到设备直接通信的方式)，因此具有更高的频谱效率以及更低的传输时延。对于D2D通信，第三代合作伙伴计划(Third Generation Partnership Project，3GPP)定义了两种传输模式：第一模式(也称为模式A)和第二模式(也称为模式B)。第一模式是网络设备为终端设备分配传输资源，第二模式是终端设备自主选择传输资源。
针对第一模式：如图1所示，终端设备的传输资源是由网络设备分配的，终端设备根据网络设备分配的资源在侧行链路上进行数据的发送；网络设备可以为终端设备分配单次传输的资源，也可以为终端设备分配半静态传输的资源；具体的，网络设备可以通过动态调度(Dynamic Grant，DG)的方式为终端设备分配侧行传输资源；或者网络设备也可以为终端分配侧行配置授权(Configured Grant，CG)传输资源。
针对第二模式：如图2所示，终端设备在资源池中选择一个传输资源进行数据的发送。
在LTE-V2X中引入了传输模式3和传输模式4，其中，传输模式3即对应上述第一模式，传输模式4即对应上述第二模式。
在NR-V2X中，支持广播传输方式、单播传输方式和组播传输方式。对于单播传输方式，如图3所示，只有一个接收端的终端设备，UE1与UE2之间进行单播传输。对于组播传输方式，接收端是一个通信组内的所有终设备，或者是在一定传输距离内的所有终端设备。对于组播传输方式，如图4所示，UE1、UE2、UE3和UE4构成一个通信组，其中UE1是发送端的终端设备，用于发送数据，该组内的UE2、UE3和UE4都是接收端的终端设备，用于接收数据。对于广播传输方式，接收端可以是任意一个终端设备，如图5所示，UE1是发送端的终端设备，用于发送数据，UE1周围的其他终端设备，如UE2、UE3、UE4、UE5、UE6和UE7都是接收端的终端设备，用于接收数据。
下面再对侧行CG进行简要说明
对于侧行CG的资源分配方式，主要包括两种配置授权方式，分别是第一类配置授权(type-1configured grant)和第二类配置授权(type-2configured grant)。
第一类配置授权：网络设备通过(Radio Resource Control，RRC)信令为终端设备配置侧行传输资源，该RRC信令配置的传输参数可以包括：时域资源、频域资源、解 调参考信号(Demodulation Reference Signal，DMRS)、调制与编码策略(Modulation and Coding Scheme，MCS)等在内的全部传输资源和传输参数。当终端设备接收到该RRC信令后，可使用所述RRC信令配置的传输参数在配置的时频资源上进行侧行传输。
第二类配置授权：采用两步的资源配置方式；首先，通过RRC信令配置包括时频资源的周期、冗余版本、重传次数、HARQ进程数等在内的传输资源和传输参数；再由下行控制信令(Downlink Control Information，DCI)激活第二类配置授权的传输，并同时配置包括时域资源、频域资源、MCS等在内的其他传输资源和传输参数。终端设备在接收到RRC信令时，不能立即使用该RRC信令所配置的传输资源和传输参数进行侧行传输，而是必须等接收到相应的DCI并配置其他传输资源和传输参数后，才能进行侧行传输。此外，网络设备还可以通过DCI去激活该配置传输，当终端设备接收到指示去激活的DCI后，不能再使用该传输资源进行侧行传输。
如果网络设备为终端设备分配了配置授权的侧行传输资源，当终端设备有侧行数据要传输时，可以直接使用该侧行传输资源进行侧行传输，而不需要向网络设备发送调度请求(Scheduling Request，SR)/缓冲状态报告(Buffer Status Report，BSR)请求传输资源，从而降低传输时延。
在侧行配置授权中，网络设备分配周期性的传输资源，并且在每个周期中，网络设备可以配置多个传输资源，如图6所示：配置授权的传输资源是周期性重复的，在每个周期内包括4个侧行传输资源。
在NR-V2X中，为了提高系统的可靠性，引入了侧行反馈信道。侧行反馈的流程示意图，如图7所示，对于单播传输方式，发送端的终端设备向接收端的终端设备发送侧行数据(包括物理侧行控制信道(Pysical Sidelink Control Channel，PSCCH)和物理侧行共享信道(Pysical Sidelink Share Channel，PSSCH))，接收端的终端设备向发送端的终端设备发送反馈信息，如混合自动重传请求(Hybrid Automatic Repeat reQuest，HARQ)反馈信息；发送端的终端设备根据接收端的终端设备的反馈信息判断是否需要进行数据重传。其中，HARQ反馈信息承载在侧行反馈信道中，例如物理侧行反馈信道(Physical Sidelink Feedback Channel，PSFCH)。发送端的终端设备可以决定是否需要接收端的终端设备发送反馈信息，例如对于广播通信，发送端的终端设备不需要接收端的终端设备发送反馈信息。对于单播通信，为了提高系统的可靠性，发送端的终端设备需要接收端的终端设备发送反馈信息；具体的，发送端的终端设备在侧行控制信息(Sidelink Control Information，SCI)中携带指示信息，所述指示信息用于指示接收端的终端设备是否需 要进行侧行反馈。
在NR-V2X中，若终端设备可以同时工作在第一模式和第二模式，且第一模式和第二模式分别对应的每个侧行传输都有对应的HARQ进程；由于网络设备不知道终端设备存在多少个第二模式的HARQ进程，也不知道第二模式的HARQ进程对应的进程标识，因此可能导致网络设备为终端设备指示的第一模式的HARQ进程标识与终端设备在第二模式中自主选取资源时的进程标识发生冲突。在该场景下终端设备如何确定HARQ进程标识尚无有效解决方案。
本申请实施例提供一种确定混合自动重传请求进程信息的方法，本申请实施例的确定混合自动重传请求进程信息的方法可以应用于各种通信系统，例如：全球移动通讯(global system of mobile communication，GSM)系统、码分多址(code division multiple access，CDMA)系统、宽带码分多址(wideband code division multiple access，WCDMA)系统、通用分组无线业务(general packet radio service，GPRS)、长期演进(long term evolution，LTE)系统、LTE频分双工(frequency division duplex，FDD)系统、LTE时分双工(time division duplex，TDD)系统、先进的长期演进(advanced long term evolution，LTE-A)系统、新无线(new radio，NR)系统、NR系统的演进系统、非授权频段上的LTE(LTE-based access to unlicensed spectrum，LTE-U)系统、非授权频段上的NR(NR-based access to unlicensed spectrum，NR-U)系统、通用移动通信系统(universal mobile telecommunication system，UMTS)、全球互联微波接入(worldwide interoperability for microwave access，WiMAX)通信系统、无线局域网(wireless local area networks，WLAN)、无线保真(wireless fidelity，WiFi)、下一代通信系统或其他通信系统等。
通常来说，传统的通信系统支持的连接数有限，也易于实现，然而，随着通信技术的发展，移动通信系统将不仅支持传统的通信，还将支持例如，D2D通信，机器到机器(machine to machine，M2M)通信，机器类型通信(machine type communication，MTC)，以及车辆间(vehicle to vehicle，V2V)通信等，本申请实施例也可以应用于这些通信系统。
本申请实施例中涉及的网络设备，可以是普通的基站(如NodeB或eNB或者gNB)、新无线控制器(new radio controller，NR controller)、集中式网元(centralized unit)、新无线基站、射频拉远模块、微基站、中继(relay)、分布式网元(distributed unit)、接收点(transmission reception point，TRP)、传输点(transmission point，TP)或者任何其它设备。本申请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。为方便 描述，本申请所有实施例中，上述为终端设备提供无线通信功能的装置统称为网络设备。
在本申请实施例中，终端设备可以是任意的终端，比如，终端设备可以是机器类通信的用户设备。也就是说，该终端设备也可称之为用户设备、移动台(mobile station，MS)、移动终端(mobile terminal)、终端(terminal)等，该终端设备可以经无线接入网(radio access network，RAN)与一个或多个核心网进行通信，例如，终端设备可以是移动电话(或称为“蜂窝”电话)、具有移动终端的计算机等，例如，终端设备还可以是便携式、袖珍式、手持式、计算机内置的或者车载的移动装置，它们与无线接入网交换语言和/或数据。本申请实施例中不做具体限定。
可选的，网络设备和终端设备可以部署在陆地上，包括室内或室外、手持或车载；也可以部署在水面上；还可以部署在空中的飞机、气球和人造卫星上。本申请的实施例对网络设备和终端设备的应用场景不做限定。
可选的，网络设备和终端设备之间以及终端设备和终端设备之间可以通过授权频谱(licensed spectrum)进行通信，也可以通过非授权频谱(unlicensed spectrum)进行通信，也可以同时通过授权频谱和非授权频谱进行通信。网络设备和终端设备之间以及终端设备和终端设备之间可以通过7吉兆赫(gigahertz，GHz)以下的频谱进行通信，也可以通过7GHz以上的频谱进行通信，还可以同时使用7GHz以下的频谱和7GHz以上的频谱进行通信。本申请的实施例对网络设备和终端设备之间所使用的频谱资源不做限定。
本申请实施例描述的系统架构以及业务场景是为了更加清楚的说明本申请实施例的技术方案，并不构成对于本申请实施例提供的技术方案的限定，本领域普通技术人员可知，随着网络架构的演变和新业务场景的出现，本申请实施例提供的技术方案对于类似的技术问题，同样适用。
本申请实施例提供的应用确定混合自动重传请求进程信息的方法的一种可选处理流程，如图8所示，包括以下步骤：
步骤S101，第一终端设备根据网络设备指示的第一HARQ进程标识，确定侧行传输对应的第二HARQ进程标识。
在一些实施例中，所述第一终端设备可以是D2D通信系统中的发送端设备。所述第一HARQ进程标识可以为网络设备为第一终端设备分配侧行传输资源时指示的HARQ进程(process)标识(Identify，ID)。
网络设备为第一终端设备分配侧行传输资源可以有两种分配分时，分别是通过DCI 动态分配侧行传输资源和通过侧行配置授权分配半静态的传输资源。在动态分配侧行传输资源的方式中，网络设备在DCI中指示第一HARQ进程标识，第一终端设备在网络设备分配的侧行传输资源上传输PSCCH/PSSCH。在侧行数据传输中，第一终端设备在SCI中向第二终端设备指示第一HARQ进程标识，以便于第二终端设备进行数据合并和反馈等。但是，由于第一终端设备还可以同时以自主选择传输资源的方式进行侧行数据传输，因此，网络设备向第一终端设备指示的第一HARQ ID可能已经被终端设备自主选择传输资源进行数据传输时使用。在该场景下，第一终端设备存在多个HARQ进程，且多个HARQ进程的HARQ进程标识存在冲突的情况；下面针对网络设备指示的第一HARQ进程标识的使用情况对本申请实施例提供的确定混合自动重传请求进程信息的方法进行说明。
在一些实施方式中，若所述第一HARQ进程标识未被所述第一终端设备使用，则所述第一终端设备确定所述第二HARQ进程标识等于所述第一HARQ进程标识。其中，所述第一HARQ进程标识未被所述第一终端设备使用可以是所述第一HARQ进程标识未被所述第一终端设备自主选取传输资源时使用。这里，网络设备向所述第一终端设备指示的第一HARQ进程标识的数量可以为一个，也可以为多个。
在另一些实施方式中，若所述第一HARQ进程标识被所述第一终端设备使用，则所述第一终端设备确定所述第一HARQ进程标识之外的未被使用的HARQ进程标识为所述第二HARQ进程标识。这里，网络设备向所述第一终端设备指示的第一HARQ进程标识的数量可以为一个，也可以为多个。可以理解为，无论所述第一HARQ进程标识的数量为多少，所述第一终端设备需要确认所述第一HARQ进程标识中被所述第一终端设备使用的进程标识的数量；然后所述第一终端设备再确定自身未被使用的HARQ进程标识为所述第二HARQ进程标识。举例来说，网络设备向所述第一终端设备指示的第一HARQ进程标识的数量为N个，第一HARQ进程标识分别是A 1、A 2、A 3，…A N。如果N个第一HARQ进程标识中的K个已经被所述第一终端设备自主选取传输资源时使用(1≤K≤N)；第一终端设备可以利用自身未被使用的N个HARQ进程标识来更新或替换已经被使用的N个HARQ进程；第一终端设备也可以选取K个未被使用的HARQ进程标识来更新或替换已经被第一终端设备使用的K个第一HARQ进程标识；(N-K)个未被使用的第一HARQ进程标识保持不变。
在又一些实施方式中，在所述第一终端设备支持的全部HARQ进程均被使用的情况下，所述第一终端设备根据第一参数确定需要终止的HARQ进程。所述第一终端设 备确定所述需要终止的HARQ进程对应的HARQ进程标识为所述第二HARQ进程标识。其中，所述第一终端设备支持的全部HARQ进程可以是所述第一终端设备的侧行链路传输的全部HARQ进程。
这里，所述第一参数可以包括数据的服务质量参数和/或数据的传输模式。所述数据的服务质量参数包括下述中的至少一项：数据的优先级、数据的传输时延和数据的可靠性。
下面分别以第一参数所包括的不同内容为例，对所述第一终端设备支持的全部HARQ进程均被使用的情况下，所述第一终端设备确定第二HARQ进程标识的处理过程进行说明。
1)第一参数包括数据的优先级。
在所述第一参数仅包括数据的优先级的情况下，第一终端设备比较第一终端设备使用网络设备分配的第一HARQ进程标识对应的侧行传输资源传输的侧行数据的优先级与当前传输的所有侧行数据的优先级的高低；如果第一终端设备使用所述第一HARQ进程标识对应的侧行传输资源传输的侧行数据的优先级高于至少一个当前传输的侧行数据的优先级，则第一终端设备终止当前传输的侧行数据中优先级最低的侧行数据的HARQ进程。举例来说，若第一HARQ进程标识为一个，且当前传输的侧行数据中有两个侧行数据的优先级低于第一终端设备使用所述第一HARQ进程标识对应的侧行传输资源传输的侧行数据的优先级，则第一终端设备终止当前传输的这两个低优先级侧行数据中优先级最低的侧行数据的HARQ进程，并将终止的HARQ进程对应的HARQ进程标识作为第二HARQ进程标识。再举例来说，若第一HARQ进程标识为两个，且当前传输的侧行数据中有两个侧行数据的优先级低于第一终端设备使用所述第一HARQ进程标识对应的侧行传输资源传输的侧行数据的优先级，则第一终端设备终止当前传输的这两个低优先级侧行数据，并将终止的HARQ进程对应的HARQ进程标识作为第二HARQ进程标识。
2)第一参数包括数据的传输模式。
在所述第一参数仅包括数据的传输模式的情况下，所述第一终端设备终止当前传输的第二模式的侧行数据的HARQ进程。举例来说，所述第一终端设备可以终止当前传输的第二模式的任意一个侧行数据的HARQ进程，并将终止的HARQ进程对应的HARQ进程标识作为第二HARQ进程标识。再举例来说，所述第一终端设备可以终止当前传输的第二模式的侧行数据中优先级最低的侧行数据的HARQ进程。第一终端设备将终 止的HARQ进程对应的HARQ进程标识作为第二HARQ进程标识。可以理解为，第一模式传输的侧行数据的优先级大于第二模式传输的侧行数据；进一步的，在第二模式传输的侧行数据中，所述第一终端设备可根据侧行数据的优先级选择需要终止的侧行数据的HARQ进程，并将终止的HARQ进程对应的HARQ进程标识作为第二HARQ进程标识。
3)第一参数包括数据的传输模式和数据的优先级。
在所述第一参数据的传输模式和数据的优先级，所述第一终端设备比较网络设备分配的第一HARQ标识对应的侧行传输资源传输的侧行数据的优先级与当前传输的第二模式的所有侧行数据的优先级，如果当前传输的第二模式的侧行数据中有至少一个侧行数据的优先级低于所述第一终端设备使用所述第一HARQ标识对应的侧行传输资源传输的侧行数据的优先级，则所述第一终端设备终止当前传输的侧行数据中优先级最低的第二模式的侧行数据对应的HARQ进程，并将终止的HARQ进程对应的HARQ进程标识作为第二HARQ进程标识。如果当前传输的第二模式的侧行数据的优先级均高于所述第一终端设备使用所述第一HARQ标识对应的侧行传输资源传输的侧行数据的优先级，则不进行任何处理，或者第一终端设备终止当前传输的侧行数据中优先级最低的第一模式的侧行数据对应的HARQ进程，并将终止的HARQ进程对应的HARQ进程标识作为第二HARQ进程标识。
需要说明的是，上述第一参数包括的三种内容仅仅作为示例，第一参数包括的其他内容或其他内容的组合也适用于本申请实施例提供的确定混合自动重传请求进程信息的方法。
在一些实施例中，在所述第一HARQ进程标识中被所述第一终端设备使用的情况下，或者在所述第一终端设备支持的全部HARQ进程均被使用的情况下，所述确定混合自动重传请求进程信息的方法还可以包括：
步骤S102，所述第一终端设备确定所述第一HARQ进程标识与所述第二HARQ进程标识的对应关系。
在一些实施例中，所述确定混合自动重传请求进程信息的方法还可以包括：
步骤S103，所述第一终端设备接收所述网络设备发送的重传调度指示。
在一些实施例中，所述重传调度指示中指示所述第一HARQ进程标识，所述重传调度指示中的新数据指示域不翻转。
其中，所述新数据指示域不翻转是指所述重传调度指示中的新数据指示域的取值相 对于首次传输的调度指示中的新数据指示域的取值没有变化。
步骤S104，所述第一终端设备根据第一HARQ进程标识与第二HARQ进程标识的对应关系，确定重传所述第二HARQ进程标识对应的侧行数据。
下面基于图9对本申请实施例提供的确定混合自动重传请求进程信息的方法的详细处理流程进行说明。
步骤S201，网络设备通过动态分配的方式为第一终端设备分配侧行传输资源，并指示HARQ ID1。
步骤S202，第一终端设备在分配的侧行传输资源上向第二终端设备传输侧行数据，并且在SCI中指示HARQ ID2。
在具体实施时，如果网络设备指示的HARQ ID1没有被所述第一终端设备占用，则HARQ ID2＝HARQ ID1。如果网络设备指示的HARQ ID1已经被所述第一终端设备占用，则所述第一终端设备从未被占用的HARQ进程标识中选取一个，将其作为HARQ ID2，并且所述第一终端设备确定HARQ ID1和HARQ ID2之间的对应关系。
步骤S203，第二终端设备向第一终端设备发送侧行反馈信息。
在一些实施例中，所述侧行反馈信息可以是HARQ ACK或者HARQ NACK。
步骤S204，第一终端设备将所述侧行反馈信息上报至网络设备。
步骤S205，在侧行反馈信息是HARQ NACK的情况下，网络设备为第一终端设备动态调度重传资源，并且在DCI中指示HARQ ID1，并且DCI中的NDI域不翻转。
步骤S206，第一终端设备根据HARQ ID1和HARQ ID2之间的对应关系，即可确定是针对HARQ ID2的侧行数据的重传调度；第一终端设备对HARQ ID2的侧行数据进行重传。
需要说明的是，本申请实施例中，所述第一HARQ进程标识的数量可以是一个，也可以是多个。
应理解，在本申请的各种实施例中，上述各过程的序号的大小并不意味着执行顺序的先后，各过程的执行顺序应以其功能和内在逻辑确定，而不应对本申请实施例的实施过程构成任何限定。
本申请上述各实施例中，网络设备为第一终端设备分配侧行配置授权(包括第一类配置授权和第二类配置授权)时，网络设备可以为第一终端设备配置多个并行的侧行配置授权传输资源。
在一些实施例中，若一个侧行配置授权对应一个HARQ进程标识，则网络设备在 侧行配置授权的配置信息中指示一个HARQ进程标识。针对第一类配置授权，所述配置信息可以是RRC信令；针对第二类配置授权，所述配置信息可以是RRC信令或DCI。
在另一些实施例中，若一个侧行配置授权对应N个HARQ进程标识，N为大于1的正整数，则网络设备可以通过两种方式向第一终端设备指示一个侧行配置授权资源对应N个HARQ进程标识。下面分别对两种方式进行说明。
方式一，网络设备在侧行配置授权的配置信息中指示N个HARQ进程标识中序列号最小的第一HARQ进程标识；所述配置信息还用于指示所述第一HARQ进程的数量。举例来说，所述配置信息指示HARQ ID1和第一HARQ进程的数量N；则该侧行配置授权对应的N个HARQ进程标识是以HARQ ID1开始的N个HARQ ID。举例来说，若N＝3，HARQ ID1＝1，则该侧行配置授权对应的3个HARQ进程标识分别是1、2、和3。
方式二，网络设备在侧行配置授权的配置信息中指示全部第一HARQ进程标识。举例来说，网络设备在侧行配置授权的配置信息中指示侧行配置授权对应的N个HARQ进程标识，所述N个HARQ进程标识可以是连续的，也可以是不连续的。
本申请实施例中，网络设备为第一终端设备分配的侧行配置授权的配置信息中可以包括物理上行控制信道(Physical Uplink Control Channel，PUCCH)传输资源，用于第一终端设备向网络设备反馈侧行反馈信息，以便于网络设备分配重传资源。由于侧行传输资源是周期性的资源，因此网络设备为第一终端设备分配的PUCCH资源也是周期性的传输资源。在一个侧行配置授权对应N个HARQ进程标识的情况下，网络设备可以通过PUCCH的时域资源位置确定HARQ进程标识。
下面基于图10对本申请实施例网络设备通过PUCCH的时域资源位置确定HARQ进程标识的详细处理流程进行说明。
网络设备为第一终端设备配置了侧行配置授权传输资源，并且在每个传输周期内配置一个PUCCH资源，PUCCH资源用于第一终端设备向网络设备上报侧行反馈信息。图10所示的两个传输周期包括PUCCH1和PUCCH2；由于不同周期的PUCCH时域资源不同，因此网络设备可以根据接收到的PUCCH确定该PUCCH承载的侧行反馈信息对应的侧行数据的HARQ进程标识。例如，网络设备为该侧行配置授权配置了两个HARQ进程标识，分别是HARQ ID1和HARQ ID2；网络设备在第一个PUCCH资源上接收到PUCCH1，可以确定PUCCH1承载的侧行反馈信息对应的侧行数据的HARQ进程标识是HARQ ID1；网络设备在第二个PUCCH资源上接收到PUCCH2，可以确定 PUCCH2承载的侧行反馈信息对应的侧行数据的HARQ进程标识是HARQ ID2。
第一终端设备在PSSCH1上发送数据的新传，在SCI中指示HARQ ID1，并且NDI取值为0。第二终端设备检测失败，在PSFCH1上反馈NACK信息，第一终端设备接收PSFCH1获取NACK信息，并且在PUCCH1上向网络设备上报该NACK信息；网络设备通过DCI1为第一终端设备分配重传资源，该DCI1中指示HARQ ID1，NDI值为1，并且分配上行传输资源，即PUCCH3所使用的传输资源；第一终端设备接收网络发送的DCI1，根据HARQ ID1和NDI信息确定是针对HARQ ID1的侧行数据的重传调度，第一终端设备在该重传资源上发送PSSCH2，并且SCI中指示HARQ ID1和NDI＝0，NDI的取值相对于首次传输没有翻转，因此表示是重传的数据。第二终端设备检测成功，向第一终端设备发送ACK，第一终端设备向网络发送PUCCH3上报该ACK信息。
为实现本申请实施例所述确定混合自动重传请求进程信息的方法，本申请实施例提供一种终端设备，所述终端设备300的组成结构，如图11所示，包括：
处理单元301，配置为根据网络设备指示的第一HARQ进程标识，确定侧行传输对应的第二HARQ进程标识。
