Description

一种通信方法及相关设备
本申请要求于2019年03月21日提交中国专利局、申请号为201910218202.6、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。
车联网中的边链路上的功率控制是非常重要的，通过边链路的功率控制，既可以保证车联网中的终端设备与网络设备之间的上下行通信的质量以及终端设备之间的直接通信的质量，又可以减少该终端设备对系统中其他终端设备的干扰，还可以延长该终端设备电池的使用时间。传统的功率余量报告(powe headroom report，PHR)上报仅包括Uu口链路的PHR的上报，网络设备无法实现对边链路的闭环功控和资源分配的调整，因此，现在急需一种包含边链路信息的功率余量报告PHR的上报方法，以使得网络设备可以根据终端设备上报的PHR进行功率调整指示，合理的进行车联网中的功率控制，另外，也可以使得网络设备根据终端设备上报的PHR调整链路资源的分配。
发明内容
一方面，终端设备需要在向网络设备发送边链路PHR之前提前确定好边链路PHR，例如，根据边链路的资源分配情况来确定是基于实际传输还是基于参考格式计算该边链路PHR所包括的PH；其中，既需要解决提前多少确定好边链路PHR的问题，还需要解决确定边链路的不同资源配置模式的资源分配情况的问题；另一方面，考虑到边链路的不同资源配置模式与Uu口链路之间的载波共享以及功率共享的情况，需要解决如何合理确定发送给网络设备的边链路与Uu口链路的PHR。
