Description

一种通信方法及相关设备
本申请要求于2019年05月15日提交中国专利局、申请号为201910403420.7、申请名称为“一种通信方法及相关设备”的中国专利申请的优先权，其全部内容通过引用结合在本申请中。
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侧行链路或者边链路(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。
当前车联网中的边链路上支持混合自动重传请求(hybrid automatic repeat request，HARQ)反馈，即自动重传请求(Automatic Repeat Request，ARQ)系统里面引入前向纠错码(Forward Error Correction，FEC)子系统，在纠错能力范围内自动纠正错误，超出纠错范围则要求发射端重发，HARQ反馈使用停等协议(stop-and-wait protocol)来发送数据。在停等协议中，发送端发送一个传输块(transport block，TB)后，就停下来等待确认信息。接收端会使用信息对该TB进行肯定(例如，1比特的肯定确认(ACK，positive acknowledgement))或否定(例如，1比特的否定确认(NACK，negative acknowledgement))的确认，如果发送端接收到ACK，说明接收端接收该TB成功；如果发送端接收到NACK，说明接收端接收该TB失败，发射端可能会进行数据的重传，但是目前还没有好的机制来解决车联网中发送端的数据重传资源的请求与调度问题。

本申请中，“数据传输”可以包括以下三种情况：数据的发送，数据的接收，或者数据的发送和数据的接收。
示例性的，本申请提供的方法可应用于如图1A或图1B所示的通信系统，该系统运行时实现终端设备与终端设备之间进行相互通信，可以包括如下两种情况：
第一种情况：终端设备在网络设备覆盖范围内，终端设备与终端设备之间通过网络设备中转进行通信，如图1A所示，第一终端设备和第二终端设备之间通过网络设备中转进行通信，示意性的，第一终端设备和网络设备之间的上行方向(如箭头所示)通信链路为上行链路(uplink，UL)，网络设备和第二终端设备之间的下行方向(如箭头所示)的通信链路为下行链路(downlink，DL)，第一终端设备或第二终端设备通过Uu口分别与网络设备进行无线通信，本申请中可以将上行链路，和/或，下行链路称为Uu口链路。
第二种情况：终端设备在网络设备覆盖范围内或者不在网络设备覆盖范围内，终端设备 与终端设备之间进行直连通信。如图1B所示，第一终端设备与第二终端设备之间进行直连通信，示例性的，第一终端设备与第二终端设备之间的通信链路可以称之为侧行链路或者边链路(sidelink，SL)，示例性的，第一终端设备与第二终端设备通过PC5口进行无线通信。
第一终端设备与第二终端设备之间进行无线直连通信的SL通信资源可以由网络设备进行调度，示例性的，终端设备在网络设备覆盖范围内，终端设备与终端设备之间的无线直连通信过程可以受网络设备控制，作为数据发送端的第一终端设备可以是在网络设备配置的SL通信资源上发送控制信号和数据信号给作为数据接收端的第二终端设备。这种基站调度SL传输资源的模式可以称之为第一模式。可选的，该第一模式可以是目前第三代合作伙伴计划(3rd Generation Partnership Project，3GPP)制定的标准中所规定的mode1资源配置模式或者mode3资源配置模式。
示例性的，基站调度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，终端设备的每次数据传输都需要网络设备单独分配资源，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边链路传输资源，其中DCI可以由物理下行控制信道承载。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，网络设备在某次为终端设备分配资源之后，未来一段时间内，终端设备都可以使用上述分配的资源，特点是“一次分配，多次使用”，比如，可以包括type1配置授权(SL configured grant type-1)、type2配置授权(SL configured grant type-2)、免授权(SL grant free)、半静态调度(SL Semi-Persistent Scheduling，SL SPS)。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边链路配置授权，终端设备可以直接使用该配置授权资源传输数据，不需要额外的激活(如，通过PDCCH/DCI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，终端设备不能直接使用该配置授权资源传输数据，激活之后才能使用。grant free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边链路配置授权，终端设备可以直接使用该配置授权资源传输数据，不需要额外的激活(如，通过PDCCH/DCI激活)。半静态调度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，终端设备不能直接使用该配置授权资源传输数据，激活之后才能使用。动态授权和配置授权主要的区别在于授权，也就是资源分配的灵活性和资源分配的开销。动态授权，网络需要为终端设备的每次数据传输分配授权，资源分配灵活，但是，资源分配开销较大；配置授权，网络设备的一次授权分配，终端可以多次使用，资源分配开销较小，但是，分配的资源相当长的时间内没有变化和调整，资源分配不灵活。动态授权使用物理信道(比如PDCCH，Physical Downlink Control Channel，物理下行控制信道)来分配，分配比较迅速；配置授权使用高层信令(比如RRC信令)或者高层信令(比如RRC信令)加物理信道(比如PDCCH)来配置，资源分配较慢。
第一终端设备与第二终端设备之间的进行无线直连通信的SL通信资源也可以不受网络设备调度控制，而是由终端设备自行确定，示例性的，终端设备在网络设备通信覆盖范围内，网络设备通过系统广播(System Information Block，SIB)消息或终端设备专用无线资源控制(Radio Resource Control，RRC)信令为终端设备配置SL资源池，作为数据发送端的第一终端设备可以自主从SL资源池中获取SL通信资源来发送控制信号和数据信号给作为数据接收端的第二终端设备；或者，示例性的，终端设备在网络设备通信覆盖范围外，作为数据发送端的第一终端设备自主从预配置的SL资源池中获取边链路通信资源来发送控制信号，和/或， 数据信号给作为数据接收端的第二终端设备。示例性的，终端设备可以感知或竞争边链路传输资源。可选的，第一终端设备通过和别的终端设备竞争获得SL资源池中的合适的SL通信资源来发送控制信号，和/或，数据信号，例如，终端设备中待传输的V2X业务的优先级越高，其竞争到SL资源池中的合适的SL通信资源的机会就越大。可选的，第一终端设备还可以预存储SL资源池信息，或者，在第一终端设备接入网络时由网络设备预配置SL资源池。这种终端设备自行确定SL传输资源的模式可以称之为第二模式；可选的，该第二模式可以是目前3GPP制定的标准中所规定的mode2资源配置模式或者mode4资源配置模式。
本申请中，终端设备与终端设备之间的通信可以是单播通信，也可以是组播通信，或者是广播通信。
本申请中的第一类型配置授权可以为NR中的type1配置授权(SL configured grant type-1)或者免授权(SL grant free)。本申请中的第二类型配置授权可以为type2配置授权(SL configured grant type-2)或者LTE中的半静态调度(semi-persistent scheduling，SPS)配置授权。
应理解，图1A和图1B仅为示例性网络架构图，该网络架构还包括其他网元设备或功能单元，本申请对此并不限定。
