Description

一种通信方法及相关设备 技术领域
本申请涉及通信技术领域，并且更具体地，涉及一种通信方法方法及相关设备。
背景技术
车联网(vehicle to everthing，V2X)是智能交通运输系统的关键技术，被认为是物联网体系中最有产业潜力、市场需求最明确的领域之一，具有应用空间广、产业潜力大、社会效益强的特点，对促进汽车和信息通信产业创新发展，构建汽车和交通服务新模式新业态，推动无人驾驶、辅助驾驶、智能驾驶、网联驾驶、智能网联驾驶、自动驾驶、汽车共享等技术的创新和应用，提高交通效率和安全水平具有重要意义。车联网一般是指通过装载在车上的传感器、车载终端设备等提供车辆信息，实现车辆到车辆(vehicle to vehicle，V2V)，车辆到基础设施(vehicle to infrastructure，V2I)，车辆到网络(vehicle to Network，V2N)以及车辆到行人(vehicle to pedestrian，V2P)之间的相互通信的通信网络。一般的，在V2X场景下，终端设备与其他终端设备之间进行直连通信的通信链路可以称之为边链路或者侧行链路(sidelink，SL)。终端设备与网络设备之间的无线通信链路可以称之为上行链路(uplink，UL)或者下行链路(downlink，DL)，由于UL或DL接口可以称之为Uu口，所以UL或者DL可以称之为Uu口链路。
现有机制中，为了激活/去激活某个SL半静态调度(semi-persistent scheduling，SPS)，网络设备需要向终端设备发送SL SPS的激活/去激活信息，终端设备在接收到该激活/去激活信息后，或者成功解码该SL SPS的激活/去激活信息后，或者确认该SL SPS激活/去激活成功后，可以向网络设备反馈SL SPS确认信息，使得网络设备和终端设备对于某个SL SPS的激活/去激活的理解保持一致。
然而在存在多个具有不同参数(如周期、偏移等参数)的SL SPS，且该多个SL SPS需要同时激活/去激活的情况下，现有机制将无法保证网络设备和终端设备对于某个SL SPS资源的激活/去激活状态的理解是一致的。
发明内容
现有机制中，网络侧无法识别终端设备发送的第一信息是哪个授权的确认信息，这就导致网络设备和终端设备对于某个授权的激活/去激活状态的理解是不一致的，从而降低对授权的调度效率。

本申请实施例提供的方案可适用于图1A所示的通信系统，该通信系统可以用于实现终端设备与网络设备或者其他终端设备之间的通信，可以为以下各种通信系统，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)、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、或者第五代(5th generation，5G)移动通信系统中的新无线(new radio，NR)系统，以及其他可用于提供移动通信服务的网络系统等，本申请不做限定。
如图1A所示，该通信系统可以包括终端设备100、网络设备120、其他终端设备130。其中，该终端设备100与网络设备120之间可以通过无线通信接口(如LTE或系统者NR系统的Uu空口)进行通信，该终端设备100与其他终端设备130之间可以通过直连无线通信接口(如LTE系统或者NR系统的PC5口)进行通信。需要说明的是，图1A所示网络架构仅为示例性架构图，虽然未示出，但除图1A所示网络功能实体外，图1A所示网络还可以包括其他功能实体，如：核心网网元等，不予限制。
如图1A所示，该终端设备100，一般可以指具有与网络设备进行通信能力的设备，比如可以是用户设备(user equipment，UE)、接入终端设备、用户单元、用户站、移动站、移动台、远方站、远程终端设备、移动设备、用户终端设备、无线终端设备、用户代理、或者用户装置等。示例性的，终端设备还可以是蜂窝电话、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、个人数字处理(personal digital assistant，PDA)、具有无线通信功能的手持设备、计算设备、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(智能手表、智能手环等)、还可以为智能家具(或家电)、未来5G网络中的终端设备、未来演进的公用陆地移动通信网络(public land mobile network，PLMN)中的终端设备、或者车联网(vehicle to everything，V2X)中的车辆设备,客户终端设备(customer-premises equipment，CPE)等，本申请实施例对终端设备的具体实现形式并不做限定。本申请中的“其他终端设备”可以指的是一个终端设备，也可以指的是多个终端设备，在此不做限定。
如图1A所示，该网络设备120可以用于实现无线物理实体功能、资源调度和无线资源管理、无线接入控制以及移动性管理等功能；示例性的，该网络设备可以为无线接入网(radio  access network，RAN)设备。本申请中，涉及的网络设备，一般可以指可用于和终端设备通信的设备，比如可以是GSM系统或者CDMA系统中的基站(base transceiver station，BTS)、WCDMA系统中的节点B(nodeB，NB)、LTE系统中的演进型节点B(evolutional nodeB，eNB)、云无线接入网络(cloud radio access network，CRAN)场景下的无线控制器、中继节点站、接入点、车载设备、路边单元(road side unit，RSU)、可穿戴设备、未来5G网络中的网络设备，如NR nodeB，下一代基站(generation nodeB，gNB)，集中式单元(centralized unit，CU)，分布式单元(distribute unit，DU)或者未来演进的PLMN网络中的网络设备等，本申请实施例对网络设备的具体实现形式并不限定。
示例性的，由网络设备120调度的终端设备110和终端设备130之间的SL传输资源可以包括动态授权和配置授权这两种不同类型的传输资源。其中，动态授权，可以指的是终端设备的每次数据传输都需要网络设备单独分配资源，或者，可以指的是终端设备需要传输时，向网络设备请求动态授权并向网络设备上报该请求，网络设备基于终端设备的请求为该终端设备分配相应的授权，动态授权的特点是“一次分配，一次使用”，比如，可以是网络设备通过下行控制信息(downlink control information，DCI)动态分配给终端设备的SL传输资源，其中DCI可以由物理下行控制信道(physical downlink control channel，PDCCH)承载。配置授权可以是终端设备的每次数据传输并不总是需要网络设备单独分配资源，或者称为半静态授权，或者半静态调度等。网络设备在某次为终端设备分配配置授权资源之后，终端设备都可以使用该资源，直到网络配置释放该配置授权，其特点是“一次分配，多次使用”，比如，可以包括type1配置授权(configured grant type-1)、type2配置授权(configured grant type-2)。type1配置授权可以是网络设备通过无线资源控制(radio resource control，RRC)信令直接配置给终端设备的SL配置授权，终端设备可以直接使用该配置授权传输数据，不需要额外的激活(如，通过PDCCH/DCI激活)。配置授权配置中配置CG资源的频域位置、周期等与CG资源相关的全部参数，其中，通过周期等时域参数可以确定CG资源的时域位置。通过该类型配置的资源配置后即生效，不需要激活或者去激活。type2配置授权可以是网络设备通过RRC信令定义配置授权的周期，再通过PDCCH/DCI激活该配置授权。配置授权配置中配置周期、HARQ进程的数量等与CG资源相关的部分参数。通过该类型配置的资源配置后需要通过层1(layer 1，L1)信令或下行控制信息DCI激活或去激活，其中，层1消息一般指的是物理(physical，PHY)层消息，其中，通过DCI指示CG资源的频域位置，并通过周期和DCI中提供的时域参数可以确定CG资源的时域位置。终端设备接收到网络通过RRC消息配置的配置授权后，不能直接使用该配置授权传输数据，终端设备在成功接收到网络设备发送的针对该配置授权的激活命令之后才能使用该配置授权类型2。SL半静态调度(Semi-Persistent Scheduling，SPS)属于或者类似于type2配置授权，SL SPS可以是网络设备通过RRC信令定义SL配置授权的周期，再通过PDCCH/DCI激活该SL配置授权，终端设备不能直接使用该SL配置授权传输SL数据，激活之后才能使用。
如图1A所示，终端设备100与其他终端设备130之间可以存在多个授权，如第一授权，的授权，……，第三授权。这些授权可以是用于终端设备100与其他终端设备130之间的第二链路的周期性授权。这些授权可以是网络设备为该终端设备配置的一个或多个授权，每个授权的配置中可以包含一个授权索引。网络设备120向终端设备110发送第一授权的激活或者去激活信息后，在终端设备110接收到该第一授权的激活或者去激活信息，或者终端设备110成功接收或者解码针对第一授权的激活/去激活信息，或者终端设备110确认该第一授权激活成功或者去激活成功后，可以向网络设备120发送该第一授权的确认信息。示例性的， 终端设备可以采用上行链路媒体接入控制层协议数据单元(uplink media access control protocol data unit，UL MAC PDU)的形式向网络设备发送该第一授权的确认信息，或者终端设备将确认信息包含在UL MAC PDU中，并发送给网络设备。
示例性地，如图1B所示的一种UL MAC PDU结构示意图，一个UL MAC PDU可以由一个或多个MAC子PDU组成。每个MAC子PDU的组成内容可以为以下几种中的一种：
·仅一个MAC子头(包含填充)；
·一个MAC子头(subheader)和一个媒体接入层协议服务数据单元(media access control service data unit，MAC SDU)；
·一个MAC子头和一个媒体介入层协议控制单元(media access control control element，MAC CE)；
·一个MAC子头和填充。
其中，包含MAC CE的MAC子PDU放置在包含MAC SDU的MAC子PDU之后，且在填充MAC子PDU之前。其中填充为可选项，即填充大小可以为0。
每个MAC子头对应于一个MAC SDU或一个MAC CE或填充。其中，MAC子头也可以对应于0比特(bit)MAC CE，即由该MAC子头和0bit MAC CE组成的MAC子PDU只包含该MAC子头。除了固定大小的MAC CE，填充和大小为48bit的公共控制信道(common control channel，CCCH)的MAC SDU之外的MAC子头部由四个头部字段R/F/LCID/L组成。用于固定大小的MAC CE，填充和大小为48bit的CCCH的MAC SDU的MAC子头部由两个头部字段R/LCID组成。MAC子头是八位对齐的，其中MAC子头(subheader)的各字段代表的含义可以如下：
·R：保留bit，设置为0，无实际意义，用于占位；
·F：格式字段，仅存在于R/F/LCID/L类型的MAC子头中且每一该类型的MAC子头中都包含一个F字段，指示L字段包含的bit数，值为0表示L字段为8bit，值为1表示L字段值为16bit；
·L：长度字段，仅存在于R/F/LCID/L类型的MAC子头中且每一该类型的MAC子头中都包含一个L字段，指示对应的MAC SDU或大小可变的MAC CE的byte数。该字段有8bit和16bit两种格式大小；
·LCID：逻辑信道(logical channel，LCH)ID字段，指示相应的MAC SDU的逻辑信道类型，或者相应的MAC CE或填充的类型。每个MAC子头中都包含一个LCID字段，长度为6bit。
本申请中的“MAC PDU”可以指的是“MAC subPDU”，也可以指的是多个MAC subPDU组成的“MAC PDU”。
本申请中的业务逻辑信道可以表示终端设备承载数据的逻辑信道，或者用来标识MAC SDU的逻辑信道。
本申请中，逻辑信道标识LCID可以替换为业务标识，所述业务标识可以包括以下任一个或多个：侧行链路服务质量流标识、侧行链路逻辑信道LCH标识、侧行链路数据无线承载DRB标识、侧行链路逻辑信道组LCG标识、侧行链路业务目标标识、侧行链路分组数据单元会话标识；或者，上行链路服务质量流标识、上行链路逻辑信道LCH标识、上行链路数据无线承载DRB标识、上行链路逻辑信道组LCG标识、上行链路业务目标标识、上行链路分组数据单元会话标识。
图2A是本申请实施例提供的一种通信方法的流程示意图，下面将结合图2A，对本申请 实施例的技术方案进行具体的描述。示例性的，图2A所对应的通信方法200可以包括：
操作201：网络设备通过第一链路向终端设备发送第一授权的激活或去激活信息，所述第一授权用于第二链路通信。
该第一链路可以为该网络设备和该终端设备之间的通信链路，该第二链路可以为该终端设备和其他终端设备之间的直连通信链路，下面以该第一链路为Uu口链路，该第二链路为SL，该第一授权为第一SL SPS为例，也就是说下面实施例中的SL SPS只是SL的授权的代表，可以用其他名称代替，如“SL SPS”可以用“SL CG”或者“SL CG type2”替换。
网络设备可以通过Uu口链路的PDCCH或者DCI向终端设备发送该第一SL SPS的激活或去激活信息。
或者，网络设备还可以同时发送多个SL SPS的激活或去激活信息，或者在同一个DCI中同时激活或者去激活多个SL SPS，该多个SL SPS可以是指具有不同参数的多个SL SPS，如资源周期不同的SL SPS，资源偏移不同的SL SPS，或者授权索引不同的SL SPS，也可以是指具有相同参数的多个SL SPS。
该激活或去激活信息可以包括以下任一种或多种：激活命令，重激活命令，去激活命令，释放命令。
操作202：终端设备向网络设备发送第一信息，该第一信息用于指示该第一授权激活成功或者去激活成功。
终端设备接收到该第一授权的激活/去激活信息，或者该终端设备成功接收或者解码针对第一授权的激活/去激活信息，或者确认该第一授权激活成功或者去激活成功后，该终端设备触发或者生成该第一信息，该终端设备向网络设备发送该第一信息。该第一信息可以为RRC消息，或者为MAC CE，或者是物理(physical，PHY)消息，或者MAC PDU，或者传输块，本申请在此不限定。
或者，具体的，终端设备接收到该第一授权的激活/去激活信息，或者该终端设备成功接收或者解码针对第一授权的激活/去激活信息，或者确认该第一授权激活成功或者去激活成功后，该终端设备触发或者生成第二信息，所述终端设备将该第二信息包含于第一信息中或者封装成第一信息，该终端设备向网络设备发送该第一信息。示例性的，如果该第二信息是MAC CE或者MAC SDU，该第一信息为MAC PDU，该将第二信息封装成第一信息可以是给MAC CE或者MAC SDU加上MAC子头，封装成MAC PDU。
该第一信息或者该第二信息可以称为SL SPS确认信息，SL CG确认信息，或者其他名称，本申请在此不限定，本申请实施例中的SL SPS确认信息可以是指该第二信息，或者包含该第二信息的第一信息。以该第一信息或第二信息为SL SPS确认信息为例，若当操作201中网络设备通过第一链路向终端设备发送的是第一SL SPS的激活信息，则该第一信息可以为SL SPS激活确认信息，该SL SPS激活确认信息用于指示该SL SPS激活成功；若当操作201中网络设备通过第一链路向终端设备发送的是第一SL SPS的去激活信息，则该第一信息可以为SL SPS去激活确认信息，该SL SPS去激活确认信息用于指示该SL SPS去激活成功。本申请实施例后面将不区分第一信息是SL SPS激活确认信息还是SL SPS去激活确认信息，可以结合上下文确定，例如根据之前网络设备通过第一链路向终端设备发送的是第一SL SPS的激活信息，还是去激活信息，还是激活信息或者去激活信息，确定本申请中的“第一信息”指的是“SL SPS激活确认信息”，还是“SL SPS去激活确认信息”，还是“SL SPS激活确认信息或者SL SPS去激活确认信息”。
该第一授权可以用于第二链路通信，下面以该第一授权为第一SL SPS为例，本申请中的 第一授权也可以是CG，configured grant type-2等其他授权，本申请对此不限定。
可选的，本申请实施例中，第一信息的内容可能存在以下几种情况：
情况1：该第一信息可以包括该第一SL SPS的专用LCID。
该第一SL SPS的专用LCID可以是指和该第一SL SPS对应的专门用于SL SPS确认信息的LCID。
示例性的，可以从现有上行共享信道(uplink shared channel，UL-SCH)的预留的LCID值(例如，LCID索引index为33-51)中设置一部分用作专用LCID。例如，可以使用预留的LCID值中的m个LCID值作为专用LCID值，m为大于零的整数，其中m可以为SL上支持的CG(CG可以包括type1 CG和type2 CG)的最大数量，或者m可以为SL上支持的SL SPS(或者type2 CG)的最大数量。例如，SL SPS index等于0的SL SPS的专用LCID的LCID index可以等于33，则终端设备在触发或者生成或者发送SL SPS index等于0的SL SPS确认信息时，在该确认信息的MAC子头中的LCID字段使用取值33，或者在MAC CE中包含该LCID取值；SL SPS index等于1的SL SPS的专用LCID的LCID index可以等于34或者35，则终端设备在触发或者生成或者发送SL SPS index等于1的SL SPS确认信息时，在该确认信息的MAC子头中的LCID字段使用取值34或者35，或者在MAC CE中包含该LCID取值。这样终端设备在发送某一SL SPS确认信息时，可以在该SL SPS确认信息中包括该SL SPS(或者SL SPS index)的专用LCID，例如，可以在该确认信息的MAC子头中的LCID字段使用该专用LCID取值，或者在MAC CE中包含该专用LCID取值，网络设备可以根据接收到的该SL SPS确认信息中包括的该SL SPS专用LCID确定该SL SPS激活/去激活成功。
示例性的，终端可以采用MAC CE的形式向网络设备发送该第一信息，该MAC CE对应的MAC subheader包括第一SL SPS的专用LCID。
例如，该MAC CE对应的MAC subheader中可以包括第一SL SPS的专用LCID。可选的，该MAC CE可以为0bit MAC CE，如图2B中a所示。当然也可以不是0bit MAC CE，例如，该MAC CE可以包括用于指示该MAC CE的MAC subheader中专用LCID对应的SL SPS激活成功还是去激活成功，本申请实施例对于该MAC CE的格式不限定。可选的，第一信息可以为MAC SDU，该MAC SDU或者该MAC SDU对应的子头中包含的内容可以参照上述MAC CE，在此不再赘述。
示例性的，终端设备可以采用UL MAC PDU的形式向网络设备发送该第一信息,该UL MAC PDU可以包括MAC subheader和MAC CE。可以在该UL MAC PDU中的MAC subheader中包括第一SL SPS的专用LCID，或者在该UL MAC PDU中的MAC CE中包括第一SL SPS的专用LCID。
例如，该UL MAC PDU中的MAC subheader中可以包括第一SL SPS的专用LCID。可选的，该UL MAC PDU中的MAC CE可以为0bit MAC CE，如图2B中a所示。当然也可以不是0bit MAC CE，例如，该MAC CE可以包括用于指示该UL MAC PDU中的MAC subheader中专用LCID对应的SL SPS激活成功还是去激活成功，本申请实施例对于该MAC CE的格式不限定。可选的，该UL MAC PDU可以包括该MAC subheader和MAC SDU，该MAC SDU中包含的内容可以参照上述MAC CE，在此不再赘述。
示例性的，可以从现有上行共享信道(uplink shared channel，UL-SCH)的预留的LCID值(例如，LCID索引index为33-51)中设置一部分用作专用LCID。例如，可以使用预留的LCID值中的m个LCID值作为专用LCID值，m为大于零的整数，当m小于SL上支持的CG(CG可以包括type1 CG和type2 CG)的最大数量，或者m小于SL上支持的SL SPS(或者type2 CG)的最 大数量。由网络设备来保证不同的SL SPS使用不同的专用LCID。例如，网络设备配置SL SPS index的取值为1的SL SPS使用的LCID值为1，当网络设备接收到SL SPS index的取值为1的SL SPS的激活或者去激活确认后，可将取值为1的LCID分配给后续的SL SPS或者SL SPS index。
情况2：该第一信息可以包括该第一SL SPS对应的第一链路业务LCID。
该第一链路业务LCID既可以用于SL SPS确认信息，也可以用于标识传输第一链路业务的逻辑信道。本申请中的第一链路业务逻辑信道的LCID可以是用于标识第一链路的业务逻辑信道的ID值，可以是现有UL-SCH中的用于Uu口链路的业务逻辑信道的标识(例如，LCID索引index为1-32)，也可以是其他可以传输业务数据的逻辑信道的ID值，本申请对此不限定。
示例性的，可以从现有UL-SCH的用于第一链路业务逻辑信道的标识的第一链路业务LCID(例如，LCID索引index为1-32)中设置一部分用作SL SPS对应的第一链路业务LCID。例如，可以使用第一链路业务LCID值中的m个LCID值作为SL SPS对应的第一链路业务LCID值，m为大于零的整数，其中m可以大于或者小于或者等于SL上支持的CG(CG可以包括type1 CG和type2 CG)的最大数量，或者m可以大于或者小于或者等于SL上支持的SL SPS(或者type2 CG)的最大数量。例如，SL SPS index等于0的SL SPS对应的第一链路业务LCID的LCID index可以等于0，SL SPS index等于1的SL SPS对应的第一链路业务LCID的LCID index可以等于1或者2。这样终端设备在发送某一SL SPS确认信息时，可以在该SL SPS确认信息中包括该SL SPS(或者SL SPS index)对应的第一链路业务LCID，网络设备可以根据接收到的该SL SPS确认信息中包括的该SL SPS对应的第一链路业务LCID确定该SL SPS激活/去激活成功。当m小于SL上支持的CG(CG可以包括type1 CG和type2 CG)的最大数量，或者m小于SL上支持的SL SPS(或者type2 CG)的最大数量时，可参考情况1中的描述。
示例性的，终端可以采用MAC CE的形式向网络设备发送该第一信息，该MAC CE对应的MAC subheader包括第一SL SPS的专用LCID。
例如，该MAC CE对应的MAC subheader中可以包括第一SL SPS对应的第一链路业务LCID。可选的，该MAC CE可以为0bit MAC CE，如图2B中a所示。当然也可以不是0bit MAC CE，例如，该MAC CE可以包括用于指示该MAC CE的MAC subheader中对应的第一链路业务LCID对应的SL SPS激活成功还是去激活成功，本申请实施例对于该MAC CE的格式不限定。可选的，第一信息可以为MAC SDU，该MAC SDU或者该MAC SDU对应的子头中包含的内容可以参照上述MAC CE，在此不再赘述。
示例性的，终端设备可以采用UL MAC PDU的形式向网络设备发送该第一信息,该UL MAC PDU可以包括MAC subheader和MAC CE。可以在该UL MAC PDU中的MAC CE中包括第一SL SPS对应的第一链路业务LCID，或者在该UL MAC PDU中的MAC CE中包括第一SL SPS对应的第一链路业务LCID。
例如，该UL MAC PDU中的MAC subheader中可以包括第一SL SPS对应的第一链路业务LCID。可选的，该UL MAC PDU中的MAC CE可以为0bit MAC CE，如图2B中b所示。这样网络设备根据接收到的第一信息中包括的0 bit MAC CE可以确定该MAC PDU是SL SPS确认信息，而不是UL-SCH的数据，再根据该MAC subheader中第一SL SPS对应的第一链路业务LCID确定该SL SPS确认消息对应于第一SL SPS，进而可以确定第一SL SPS激活成功或者去激活成功。当然该UL MAC PDU中的MAC CE也可以不是0bit MAC CE，例如，该MAC CE可以包括用于指示该UL MAC PDU中的MAC subheader中LCID对应的SL SPS激活成功还是去激活成 功，本申请对于该MAC CE的格式不限定。可选的，该UL MAC PDU可以包括MAC subheader和MAC SDU，该MAC SDU中包含的内容可以参照上述MAC CE，在此不再赘述。
示例性的，终端设备可以采用UL MAC PDU的形式向网络设备发送第一信息,该UL MAC PDU可以包括MAC subheader和MAC CE，第二信息包含在第一信息中，且此时第二信息可以是SL SPS确认信息或者SL SPS激活或去激活确认MAC CE。可选的，该MAC CE可以为0bit MAC CE，这样网络设备根据接收到的第二信息为0 bit MAC CE可以确定该MAC CE表示SL SPS确认信息，而不是UL-SCH的数据，再根据该MAC subheader中第一SL SPS对应的第一链路业务LCID确定该MAC CE是对应于第一SL SPS，进而可以确定第一SL SPS激活成功或者去激活成功。当然该MAC CE也可以不是0bit MAC CE，例如，该MAC CE可以包括用于指示该MAC CE对应的MAC subheader中LCID对应的SL SPS激活成功还是去激活成功，本申请对于该MAC CE的格式不限定。
示例性的，在情况1和情况2中的SL SPS(或者SL SPS index)与专用LCID或者第一链路业务LCID的对应关系可以不仅仅是一一对应，如SL SPS(或者SL SPS index)与专用LCID或者第一链路业务LCID是一对多的对应关系，即存在多个专用LCID或者第一链路业务LCID对应一个SL SPS(或者SL SPS index)的情况。
可能的上述SL SPS index与LCID index的对应关系可以如表1所示，

情况1和情况2均是建立UL-SCH的LCID与SL SPS(或者SL SPS index)之间的对应关系，区别在于情况1是在预留的LCID取值中取出一部分用作SL SPS专用LCID，即将SL SPS(或者SL SPS index)与index在33-51之间的部分或者全部预留LCID相关联；而情况2是将SL SPS(或者SL SPS index)与业务逻辑信道标识进行绑定，即将SL SPS(或者SL SPS index)与index在 业务逻辑信道标识范围内的部分或者全部业务LCID相关联。
情况3：该第一信息中可以包括该第一SL SPS对应的SL LCH的LCID。

该第一授权的类型可以为配置授权，例如SL configured grant type-2，SL SPS，或者动态授权。如果该第一授权为第一SL SPS，那么在网络设备通过第一链路向终端设备发送第一SL SPS的激活或去激活信息之前，网络设备还需要通过第一链路向终端设备发送第一SL SPS的配置信息，例如网络设备通过RRC信令向终端设备发送第一授权的周期，偏移等参数。
下面实施例中以该第一授权为第一SL SPS为例，也就是说下面实施例中的SL SPS只是SL授权的代表，可以用其他SL授权类型代替。
网络设备可以通过Uu口链路的PDCCH或者DCI向终端设备发送该第一SL SPS的激活或去激活信息。或者，网络设备还可以同时发送多个SL SPS的激活或去激活信息，或者在同一个DCI中同时激活或者去激活多个SL SPS，该多个SL SPS可以是指具有不同参数的多个SL SPS，如资源周期不同的SL SPS，资源偏移不同的SL SPS，或者授权索引不同的SL SPS，也可以是指具有相同参数的多个SL SPS。

图4A是本申请提供的一种通信方法的流程示意图，下面将结合图4A，对本申请实施例的技术方案进行具体的描述。示例性的，图4A所对应的通信方法500可以包括：
操作501：网络设备向终端设备发送第一授权的激活/去激活信息，该第一授权用于第二链路通信。
该第一链路可以为该网络设备和该终端设备之间的通信链路，该第二链路可以为该终端设备和其他终端设备之间的直连通信链路，下面以该第一链路为Uu口链路，该第二链路为SL例。
该第一授权的类型可以为配置授权，例如SL configured grant type-2，SL SPS，或者动态授权。如果该第一授权为第一SL SPS，那么在网络设备通过第一链路向终端设备发送第一SL SPS的激活或去激活信息之前，网络设备还需要通过第一链路向终端设备发送第一SL SPS的配置信息，例如网络设备通过RRC信令向终端设备发送第一SL SPS的周期。
下面实施例中以该第一授权为第一SL SPS为例，也就是说下面实施例中的SL SPS只是SL的授权的代表，可以用其他类型授权代替。
网络设备可以通过Uu口链路的PDCCH或者DCI向终端设备发送该第一SL SPS的激活或去激活信息。或者，网络设备还可以同时发送多个SL SPS的激活或去激活信息，或者在同一个DCI中同时激活或者去激活多个SL SPS，该多个SL SPS可以是指具有不同参数的多个SL SPS，如资源周期不同的SL SPS，资源偏移不同的SL SPS，或者授权索引不同的SL SPS，也可以是指具有相同参数的多个SL SPS。

可选地，第一指示信息用于直接指示多个SL SPS(或者SL SPS index)分别与一个或多个第二授权的授权索引(index)的对应关系。即，第一指示信息可以为一个对应关系的列表，列表中的每一行指一个SL SPS或者SL SPS index，以及该SL SPS或者SL SPS index关联的第二授权。
当第二授权是UL CG，则因为Uu口上可能只支持一个激活的UL CG，或者说在同一时刻只能存在一个激活的UL CG，在这种场景下，如图4B所示，该第一指示信息可以用于指示该终端设备在该第二授权的第一传输机会上发送该第一信息，该第二授权可以是用于Uu口链路通信的周期性UL CG。示例性的，该第一指示信息可以采用第一参数指示该UL CG的传输机会。
例如，若该第一参数为“0”，表示利用该UL CG的一个周期内的首次传输机会反馈该第 一信息，可以是指该传输机会和该第一参数下发时刻之间的时间差小于该UL CG的一个周期，或者可以是指该传输机会和该SL SPS激活/去激活信息下发时刻之间的时间差小于该UL CG的一个周期，或者可以是指该传输机会和该第一信息触发时刻之间的时间差小于该UL CG的一个周期，或者可以是指该传输机会和该UL CG激活/去激活信息下发时刻之间的时间差小于该UL CG的一个周期，或者可以是指该传输机会和该UL CG确认信息触发时刻之间的时间差小于该UL CG的一个周期，或者可以是指该传输机会和该UL CG起始时刻之间的时间差小于该UL CG的一个周期；
若该第一参数为“1”，则表示在该UL CG的一个周期后的首次传输机会反馈该第一信息可以是指该传输机会和该第一参数下发时刻之间的时间差小于该UL CG的大于该UL CG一个周期或者小于该UL CG两个周期，或者可以是指该传输机会和该SL SPS激活/去激活信息下发时刻之间的时间差大于该UL CG一个周期或者小于该UL CG两个周期，或者可以是指该传输机会和该第一信息触发时刻之间的时间差大于该UL CG一个周期或者小于该UL CG两个周期，或者可以是指该传输机会和该UL CG激活/去激活信息下发时刻之间的时间差小于该UL CG的两个周期，或者可以是指该传输机会和该UL CG确认信息触发时刻之间的时间差小于该UL CG的两个周期，或者可以是指该传输机会和该UL CG起始时刻之间的时间差小于该UL CG的两个周期；
以此类推，若该第一参数为“2”，即第一参数的字段长度大于1比特，则表示在该UL CG的两个周期后的首次传输机会上上报该第一信息，不再赘述。
可选地，第一参数的取值为UL CG的周期的整数倍。
可选的，在Uu口上只支持一个激活的UL CG场景下，网络设备可以给不同的SL SPS配置不同的定时器配置信息，例如该第一指示信息可以是个第一定时器配置信息，
终端设备可以在接收到该第一SL SPS激活/去激活信息时启动该第一定时器，该第一定时器超时后触发或者生成该第一信息或者该终端设备触发或者生成第二信息，该终端设备将该第二信息包含于第一信息中或者封装成第一信息，然后，该终端设备可以在该第一定时器超时后的该UL CG的传输机会上发送该第一信息，例如可以是在该第一定时器超时后的第一个该UL CG传输机会上发送该第一信息。
操作501中的第一授权的激活或去激活信息和第一指示信息也可以不是相互包含的关系，例如网络设备可以将该第一授权的激活或去激活信息和该第一指示信息同时发送给终端设备，即该两条信息携带在不同消息中同时发送给终端设备，当然也可以不同时发送，本申请在此限定。
操作502：网络设备向终端设备发送该第二授权的配置信息，或者，该第二授权的激活/去激活信息，该第二授权用于Uu口链路通信。
该第二授权可以是上行链路配置授权(UL CG)，包括type1 CG或者type2 CG，则该网络设备可以向终端设备发送UL CG的配置信息，或者，该UL CG的激活信息/去激活信息。或者，该第二授权可以是上行链路动态授权(UL DG)，则该网络设备可以向终端设备发送该UL DG的激活信息/去激活信息。
可选的，该第二授权的配置信息中可以包括第二指示信息，该第二指示信息可以用于指示该第二授权上可以发送的一个或多个SL SPS确认信息。该一个或多个SL SPS中包括该第一SL SPS，或者该一个或多个SL SPS确认信息中包括该第一信息。
可选的，该第二授权的激活或去激活信息中可以包括第二指示信息，该第二指示信息可以用于指示该第二授权上可以发送的一个或多个SL SPS确认信息。该一个或多个SL SPS中 包括该第一SL SPS，或者该一个或多个SL SPS确认信息中包括该第一信息。

第二指示信息中的标识可以和第一指示信息中的标识一样，第二指示信息中的标识也可以和第一指示信息中的标识不一样，例如可以具有一一对应的关系，或者一对多的关系，或者多对一的关系，如表5所示：
表5：
Figure PCTCN2019101214-appb-000005
则根据表3，表4和表5，SL SPS和CG/DG实际上通过该第一指示信息中的标识和第二指示信息中的标识建立了对应关系，该SL SPS和CG/DG之间的对应关系可以是一对多的关系，即终端设备只能使用与某个SL SPS(或者SL SPS index)具有对应关系的UL CG/DG上报该SL SPS的确认信息；一种可能的该SL SPS和CG/DG之间的对应关系可以如表6所示：
表6：
Figure PCTCN2019101214-appb-000006
终端设备可以根据表6所示的SL SPS和CG/DG之间的对应关系，确定SL SPS确认信息可以在哪个或哪几个UL CG/DG上发送，网络设备则可以根据接收到该SL SPS确认信息的UL CG/DG来确定哪个SL SPS激活成功/去激活成功。
可选的，第二授权的配置/激活/去激活信息和第二指示信息也可以不是相互包含的关系，例如网络设备可以将该第一授权的配置/激活/去激活信息和该第二指示信息同时发送给终端设备，即该两条信息携带在不同消息中同时发送给终端设备，当然也可以不同时发送，本申请在此限定。
可选的，该第二授权的激活或去激活信息中也可以不需要包括第二指示信息，或者说，网络设备可以不需要发送该第二指示信息给终端设备，例如在Uu口上只支持一个激活的UL CG场景下，终端设备可以默认就是在当前激活的UL CG上发送一个或多个SL SPS确认信息，然后终端设备可以根据该第一指示信息确定具体在当前激活的UL CG上的哪一个传输机会 发送一个或多个SL SPS确认信息。
上述操作501和操作502的先后顺序可以交换，即本申请实施例不限定先发第一授权的激活/去激活信息还是先发第二授权的配置/激活/去激活信息，或者是先发第一指示信息还是先发第二指示信息。
上述操作501和502也可以合并，或者说网络设备可以将该第一授权的激活或去激活信息，该第一指示信息，该第二授权的激活或去激活信息，该第二指示信息，合并在一起发送，例如，该四条信息携带在一条消息中发送给终端设备。当然，该四条信息也可以携带在不同消息中同时发送给终端设备，本申请对此不限定。
操作503：终端设备向网络设备发送第一信息，该第一信息用于指示该第一授权激活成功或者去激活成功。
该终端设备可以根据操作501和/或操作502中获得的SL SPS和CG(或者UL CG传输机会上)/DG之间的对应关系，在与该第一SL SPS对应的UL CG(或者对应的UL CG传输机会上)/DG上发送该第一信息。
终端设备接收到该第一SL SPS的激活/去激活信息，或者该终端设备成功接收或者解码针对第一SL SPS的激活/去激活信息，或者确认该第一SL SPS激活成功或者去激活成功后，该终端设备触发或者生成该第一信息，该终端设备向网络设备发送该第一信息；或者，该终端设备触发或者生成第二信息，该终端设备将该第二信息包含于第一信息中或者封装成第一信息，该终端设备向网络设备发送该第一信息。示例性的，如果该第二信息是MAC CE或者MAC SDU，该第一信息为MAC PDU，该将第二信息封装成第一信息可以是给MAC CE或者MAC SDU加上MAC子头，封装成MAC PDU。
该第一信息可以为RRC消息，或者为MAC CE，或者是物理(physical，PHY)消息，或者传输块，本申请在此不限定。
