具体实施方式
下面将结合附图，对本申请中的技术方案进行描述。
本申请中，“至少一个”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的情况，其中A，B可以是单数或者复数。字符“/”一般表示前后关联对象是一种“或”的关系。“以下中的至少一项(个)”或其类似表达，是指的这些项中的任意组合，包括单项(个)或复数项(个)的任意组合。例如，a，b或c中的至少一项(个)，可以表示：a、b、c、a-b、a-c、b-c、或a-b-c，其中a、b、c可以是单个，也可以是多个。另外，在本申请的实施例中，“第一”、“第二”等字样并不对数目和执行次序进行限定。此外，在本申请实施例中，“301”、“402”、“503”等字样仅为了描述方便作出的标识，并不是对执行步骤的次序进行限定。
需要说明的是，本申请中，“示例性的”或者“例如”等词用于表示作例子、例证或说明。本申请中被描述为“示例性的”或者“例如”的任何实施例或设计方案不应被解释为比其他实施例或设计方案更优选或更具优势。确切而言，使用“示例性的”或者“例如”等词旨在以具体方式呈现相关概念。
本申请实施例的技术方案可以应用于各种通信系统，例如：全球移动通信(global system for mobile communications，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)、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、未来的第五代(5th generation，5G)系统或新无线(new radio，NR)等。此外，本申请实施例的技术方案可以应用于面向未来的通信技术，只要采用新通信技术的通信系统包括D2D通信，都适用本发明实施例提供的技术方案。本发明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发明实施例的技术方案，并不构成对于本发明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，本发明实施例提供的技术方案对于类似的技术问题，同样适用。
D2D场景可以分为有网络覆盖、部分网络覆盖和没有网络覆盖3种，如图1所示。有网络覆盖的场景下，所有D2D设备在网络装置的覆盖范围内；部分网络覆盖的场景下有一部分D2D设备在网络装置的覆盖范围内，另一部分D2D设备不在网络装置的覆盖范围；没有网络覆盖的场景下，所有D2D设备都不在网络装置的覆盖范围。例如，终端装置1能接收到网络装置的信号，为有网络覆盖的场景，该终端装置1为网络覆盖范围内的终端装置；又如，终端装置2无法接收到网络装置的信号，能接收到网络覆盖内的终端装置1的信号，为部分网络覆盖的场景，该终端装置2为部分网络覆盖范围的终端装置；又如，终端装置3无法接收前两种信号，为没有网络覆盖的场景，该终端装置3为网络覆盖范围外的终端装置。
新无线接入技术(new radio access technology，NR)是目前主流的无线通信技术，其针对D2D业务特性及新的业务需求，可以支持更低延迟、更高可靠性的D2D通信。图2即示出了一种D2D网络系统架构图，在图中所示的D2D系统中，主要存在两种空中接口，即终端装置与网络装置之间的通信接口(Uu口)和终端装置与终端装置(如图2中的终端装置A与终端装置B)之间的通信接口(PC5口)，其中Uu口用于终端装置与网络装置或路侧单元之间的通信，PC5口用于终端装置与终端装置之间的SL通信。
D2D设备通信的资源分配主要有两种模式。模式一(Mode 1)是集中控制式的方法，D2D的资源由网络装置进行分配，资源通过调度的方式分配给发送端终端装置使用，集中控制式资源分配主要针对有网络覆盖的场景。模式二(Mode 2)是基于竞争的分布式资源复用方法，由发送端终端装置通过竞争的方式从资源池中获得发送资源。在有网络覆盖的场景下，资源池是由网络装置分出的一整块资源，D2D终端装置在该一整块资源中竞争资源。在没有网络覆盖的场景下，资源池是D2D终端装置能够获得的一块预定义资源，D2D终端装置在该预定义资源下竞争资源。
D2D设备发现的资源分配主要有两种类型。类型一(Type 1)是基于竞争的分布式资源复用方法，由发送端终端装置通过竞争的方式从资源池中获得资源。在有网络覆盖的场景下，资源池是由网络装置分出的一整块资源，D2D终端装置在该一整块资源中竞争资源。在没有网络覆盖的场景下，资源池是D2D终端装置能够获得一块预定义资源，D2D终端装置在该预定义资源下竞争资源。类型二(Type 2)是集中控制式的方法，D2D的资源由网络装置进行分配，资源通过调度的方式分配给发送端终端装置使用，集中控制式资源分配主要针对有网络覆盖场景。
为了提升交通系统的安全性和智能化，智能交通系统的概念正逐渐兴起。智能交通可以利用新一代的通信网络和数据处理能力，提高交通系统的整体效率，降低能量损耗，增加运输的安全性和便捷程度。V2X是未来智能交通运输系统的关键技术。其通过车辆到车 辆(vehicle to vehicle，V2V)通信、车辆到基础设施(vehicle to infrastructure，V2I)通信、车辆到路人(vehicle to pedestrian，V2P)通信以及车辆到网络(vehicle to network，V2N)通信等通信方式，能够获得实时路况、道路信息、行人信息等一系列交通信息，从而提高驾驶安全性、减少拥堵、提高交通效率、提供车载娱乐信息等。图3示出了一种V2X通信的场景，如图3所示，车辆之间通过V2V进行通信时，车辆可以将自身的车速、行驶方向、具体位置、是否踩了紧急刹车等信息广播给周围车辆。周围车辆的驾驶员通过获取该类信息，可以更好的感知视距外的交通状况，从而对危险状况作出预判和避让。而对于V2I通信，除了有上述安全信息的交互外，路边基础设施例如路侧单元(road side unit，RSU)还可以为车辆提供各类服务信息和数据网络的接入，例如停车收费、车内娱乐等，这些功能都极大的提高了交通智能化。
本申请涉及终端装置可以为包含无线收发功能、且可以为用户提供通讯服务的设备或者设备中的模块。具体地，终端装置可以为V2X系统中的设备、D2D系统中的设备、MTC系统中的设备等，如车、车内具有收发功能、为用户提供通讯符合的通信装置等。例如，终端装置可以指工业机器人、工业自动化设备、用户设备(User Equipment，UE)、接入终端、用户单元、用户站、移动站、移动台、远方站、远程终端、移动设备、用户终端、终端、无线通信装置、用户代理或用户装置。例如，终端装置还可以是蜂窝电话、无绳电话、会话启动协议(session initiation protocol，SIP)电话、无线本地环路(wireless local loop，WLL)站、个人数字助理(personal digital assistant，PDA)、具有无线通信功能的手持设备、计算设备或连接到无线调制解调器的其它处理设备、车载设备、可穿戴设备，5G网络或5G之后的网络中的终端装置或者未来演进的公用陆地移动通信网络(public land mobile network，PLMN)中的终端装置等，本申请实施例对此并不限定。
本申请实施例中的网络装置可以是用于与终端装置通信的设备，该网络装置可以是全球移动通信(global system for mobile communications，GSM)系统或码分多址(code division multiple access，CDMA)中的基站(base transceiver station，BTS)，也可以是宽带码分多址(wideband code division multiple access，WCDMA)系统中的基站(NodeB，NB)，还可以是LTE系统中的演进型基站(evoled NodeB，eNB或eNodeB)，还可以是云无线接入网络(cloud radio access network，CRAN)场景下的无线控制器，或者该网络装置可以为中继站、接入点、车载设备、车联网系统中的路侧单元(road side unit，RSU)、可穿戴设备以及未来5G网络中的网络装置或者未来演进的PLMN网络中的网络装置等，本申请实施例并不限定。

在LTE中，网络装置下行发送物理下行共享信道(physical downlink shared channel，PDSCH)，终端装置在物理上行控制信道(physical uplink control channel，PUCCH)或物理上行共享信道(physical uplink shared channel，PUSCH)上反馈混合自动重传请求-确定(hybrid automatic repeat request acknowledgement，HARQ-ACK)、混合自动重传请求-否定确认(hybrid automatic repeat request negative acknowledgement，HARQ-NACK)、或非连续传输(discontinuous transmission，DTX)，以告知网络装置是否正确接收PDSCH。如果终端装置发送的是NACK，则网络装置可以启动PDSCH的重传。终端装置还会发送或调度请求(scheduling request，SR)给网络装置，请求网络装置调度资源。终端装置还会将测量得到的下行信道的信道状态信息(channel state information，CSI)反馈给网络装置。
在设备到设备(device to device，D2D)、车联网(V2X)等系统中，发送端终端装置发送物理侧行控制信道(physical sidelink control channel，PSCCH)或物理侧行共享信道(physical sidelink shared channel，PSSCH)，接收端终端装置可以向发送端终端装置或网络装置发送侧行混合自动重传请求-确定(sidelink hybrid automatic repeat request acknowledgement，SL HARQ-ACK)、侧行混合自动重传请求-否定确认(sidelink hybrid automatic repeat request negative acknowledgement，SL HARQ-NACK)、或非连续传输 (discontinuous transmission，DTX)，以告知发送端终端装置或网络装置是否正确接收PSCCH或PSSCH。如果接收终端装置向网络装置发送NACK，则网络装置可以给发送终端装置调度资源用于PSSCH或PSCCH的重传。如果接收终端装置向发送终端装置发送NACK，则发送终端装置可以启动PSSCH或PSCCH的重传。如果接收终端装置向发送终端装置发送NACK，发送终端装置也可以将NACK转发给网络装置，网络装置可以给发送终端装置调度资源用于PSSCH或PSCCH的重传。发送终端装置还可以发送调度请求(sidelink scheduling request，SL SR)，请求网络装置或其他终端装置调度资源。接收端终端装置还可以将测量得到的侧行链路的侧行信道状态信息(sidelink channel state information，SL CSI)反馈给发送端终端装置或者网络装置。

为了便于描述，本申请中将HARQ-ACK、HARQ-NACK、SR以及CSI统称为上行控制信息；本申请中将SL HARQ-ACK、SL HARQ-NACK、SL SR以及SL CSI统称为侧行控制信息；将上行控制信息与侧行控制信息统称为控制信息。控制信息包括了反馈信息。侧行控制信息有时还被称为侧行反馈信息。
然而，终端装置待发送的控制信息的总开销大于终端装置可以使用的资源容量的情况下，若终端随机确定发送的控制信息，那么很有可能遗漏更重要的控制信息。因此，需要设计一种针对发送、接收控制信息的技术方案。

例如，优先级规则指示不同类型的控制信息的优先级规则，M个控制信息包括2个通信方式为广播的侧行链路对应的HARQ以及通信方式为组播的侧行链路对应的HARQ。根据该优先级规则，可以确定L等于0，即确定该M个控制信息中不包含优先级最高的控制信息，不发送该M个控制信息；可以确定L等于1，即随机确定该M个控制信息中的1个控制信息为优先级最高的控制信息；可以确定L等于2，即确定该M个控制信息中的2个控制信息为优先级最高的控制信息。

例如，N为2，该N个优先级子规则包括优先级子规则1：SL HARQ或SL SR的优先级高于SL CSI，以及优先级子规则2：通信方式为广播的侧行链路对应的侧行控制信息的优先级高于通信方式为广播的侧行链路对应的侧行控制信息的优先级。
以优先级子规则1、优先级子规则2为例，假设M个控制信息包括：通信方式为广播的侧行链路对应的SL HARQ、通信方式为组播的侧行链路对应的SL HARQ、通信方式为广播的侧行链路对应的SL CSI、通信方式为组播的侧行链路对应的SL CSI。根据优先级子规则1和优先级子规则2，终端无法判断通信方式为组播的侧行链路对应的SL HARQ和通信方式为广播的侧行链路对应的SL CSI的优先级高低，需要借助优先级子规则1和优先级子规则2的优先级来判断。假设优先级子规则1的优先级高于优先级子规则2的优先级，那么终端根据优先级子规则1，判断通信方式为广播的侧行链路对应的SL HARQ、通信方式为组播的侧行链路对应的SL HARQ的优先级均高于通信方式为广播的侧行链路对应的SL CSI、通信方式为组播的侧行链路对应的SL CSI的优先级；终端再根据优先级子规则2，判断通信方式为广播的侧行链路对应的SL HARQ的优先级高于通信方式为组播的侧行链路对应的SL HARQ的优先级，通信方式为广播的侧行链路对应的SL CSI的优先级高于通信方式为组播的侧行链路对应的SL CSI。
假设L等于1，终端装置根据优先级子规则1以及优先级子规则2，确定通信方式为广播的侧行链路对应的SL HARQ的优先级最高，该L个控制信息为通信方式为广播的侧行链路对应的SL HARQ。
在某些情况下，仅根据优先级规则靠前的优先级子规则就可以确定该L个控制信息。终端装置不需要根据优先级规则靠后的优先级子规则来确定该L个控制信息。换句话说，终端装置基于优先级子规则的优先级顺序，仅根据N个优先级子规则中的部分优先级子规则，就可以确定该L个控制信息。
假设L等于2，终端装置仅根据优先级子规则1，就可以确定通信方式为广播的侧行链路对应的SL HARQ、通信方式为组播的侧行链路对应的SL HARQ为M个控制信息中优先级最高的2个控制信息，该L个控制信息为发送方式为通信方式为广播的侧行链路对应的SL HARQ以及通信方式为组播的侧行链路对应的SL HARQ。

在一个示例中，优先级子规则D：小区编号小的小区对应的侧行控制信息的优先级高于小区编号大的小区对应的侧行控制信息的优先级；优先级子规则E：小的CSI配置标识对应的侧行控制信息的优先级高于大的CSI配置标识对应的侧行控制信息的优先级。优先级子规则D的优先级高于优先级子规则E的优先级。换句话说，先比较小区编号的大小，再比较CSI配置标识的大小。也就是说，小区编号小的小区对应且大的CSI配置标识对应的非波束相关CSI的优先级高于小区编号大的小区对应且小的CSI配置标识对应的非波束相关CSI的优先级。
在一个示例中，优先级子规则F：小的发送链路编号对应的控制信息的优先级高于大的发送链路编号对应的控制信息的优先级。优先级子规则G：通信方式为广播的侧行链路对应的侧行控制信息的优先级高于通信方式为组播的侧行链路对应的侧行控制信息的优先级。优先级子规则F的优先级低于优先级子规则G的优先级。换句话说，通信方式为广播的侧行链路对应且大的发送链路编号对应的侧行控制信息的优先级高于通信方式为组播的侧行链路对应且小的发送链路编号对应的侧行控制信息的优先级。

可选的，所述终端装置根据所述N1个优先级子规则、所述N1个优先级子规则的优先级顺序，从所述M个控制信息中确定所述L个控制信息，包括：
步骤a，确定i＝1，i为循环参数；

步骤d，根据T1至Ti个条件控制信息，判断是否能够确定所述L个控制信息，若否，则确定当前i值加1为新的i值，并返回步骤b；若是，则确定所述L个控制信息。
换句话说，终端装置可以按照优先级从高到低将该N1个优先级子规则进行排序，一个接一个地根据该N1个优先级子规则，确定该L个控制信息。

换句话说，该优先级规则包括了不同的S个控制信息的优先级顺序。根据S个控制信息中优先级最高的S1个控制信息的优先级顺序，确定该L个控制信息。例如，类型1、与属性1对应的控制信息的优先级次序为1，类型1、与属性2对应的控制信息的优先级次序为2，类型2、与属性1对应的控制信息的优先级次序为3，类型2、与属性2对应的控制信息的优先级次序为4。
