Description

冲突解决的方法和终端设备
本申请要求于2017年12月28日提交中国专利局、申请号为PCT/CN2017/119594、申请名称为“冲突解决的方法和终端设备”的PCT专利申请的优先权,以及要求于2018年2月7日提交中国专利局、申请号为PCT/CN2018/075693、申请名称为“冲突解决的方法和终端设备”的PCT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
本申请涉及通信领域,并且更具体地,涉及一种冲突解决的方法和终端设备。
背景技术
在版本(Release)14中,终端设备(例如,车载终端)可以在上行链路(Uplink)上与网络设备进行数据传输和侧行链路(Sidelink)上与其他终端进行数据传输,当上行链路传输和侧行链路传输在时间上交叠时,根据测量链路业务的优先级进行功率分配。例如,网络可以配置一个数据优先级(ProSe Per-Packet Priority,PPPP)的门限(也可以是预配置的优先级门限),当侧行链路数据的PPPP高于该门限时,终端会保证侧行数据的传输,丢弃上行传输或者降低上行数据的功率;当侧行链路的数据的PPPP小于等于该门限时,终端会保证上行数据的传输,丢弃侧行数据传输或者降低侧行数据的功率。然而,这种解决上行链路传输和侧行链路传输在时间上交叠(冲突)的方式,无法满足Release15,以及后续版本中对数据传输的要求。
发明内容

下面将结合本申请实施例中的附图,对本申请实施例中的技术方案进行清楚、完整地描述。
应理解,本申请实施例的技术方案可以应用于端到端(Device to Device,D2D)通信系统,例如,基于长期演进(Long Term Evolution,LTE)进行D2D通信的车联网系统。与传统的LTE系统中终端之间的通信数据通过网络设备(例如,基站)接收或者发送的方式不同,车联网系统采用终端到终端直接通信的方式,因此具有更高的频谱效率 以及更低的传输时延。
可选地,车联网系统基于的通信系统可以是全球移动通讯(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)、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、5G新无线(New Radio,NR)系统等。
本申请实施例中的终端设备可以是能够实现D2D通信的终端设备。例如,可以是车载终端设备,也可以是5G网络中的终端设备或者未来演进的公用陆地移动通信网络(Public Land Mobile Network,PLMN)中的终端设备等,本申请实施例并不限定。
图1和图2是本申请实施例的一个应用场景的示意图。图1示例性地示出了一个网络设备和两个终端设备,可选地,本申请实施例中的无线通信系统可以包括多个网络设备并且每个网络设备的覆盖范围内可以包括其它数量的终端设备,本申请实施例对此不做限定。
可选地,该无线通信系统还可以包括移动管理实体(Mobile Management Entity,MME)、服务网关(Serving Gateway,S-GW)、分组数据网络网关(Packet Data Network Gateway,P-GW)等其他网络实体,或者,该无线通信系统还可以包括会话管理功能(Session Management Function,SMF)、统一数据管理(Unified Data Management,UDM),认证服务器功能(Authentication Server Function,AUSF)等其他网络实体,本申请实施例对此不作限定。
具体地,终端设备20和终端设备30可以通过D2D通信模式进行通信,在进行D2D通信时,终端设备20和终端设备30通过D2D链路即侧行链路(Sidelink上,SL)直接进行通信。例如图1或者图2所示,终端设备20和终端设备30通过侧行链路直接进行通信。在图1中,终端设备20和终端设备30之间通过侧行链路通信,其传输资源是由网络设备分配的;在图2中,终端设备20和终端设备30之间通过侧行链路通信,其传输资源是由终端设备自主选取的,不需要网络设备分配传输资源。
D2D通信可以指车对车(Vehicle to Vehicle,简称“V2V”)通信或车辆到其他设备(Vehicle to Everything,V2X)通信。在V2X通信中,X可以泛指任何具有无线接收和发送能力的设备,例如但不限于慢速移动的无线装置,快速移动的车载设备,或是具有 无线发射接收能力的网络控制节点等。应理解,本发明实施例主要应用于V2X通信的场景,但也可以应用于任意其它D2D通信场景,本申请实施例对此不做任何限定。
在车联网系统中,可以存在两种类型的终端设备,即具有侦听能力的终端设备例如车载终端(Vehicle User Equipment,VUE)或行人手持终端(Pedestrian User Equipment,PUE),以及不具有侦听能力的终端设备例如PUE。VUE具有更高的处理能力,并且通常通过车内的蓄电池供电,而PUE处理能力较低,降低功耗也是PUE需要考虑的一个主要因素,因此在现有的车联网系统中,VUE被认为具有完全的接收能力和侦听能力;而PUE被认为具有部分或者不具有接收和侦听能力。如果PUE具有部分侦听能力,其资源的选取可以采用和VUE类似的侦听方法,在可侦听的那部分资源上进行可用资源的选取;如果PUE不具有侦听能力,则PUE在资源池中随机选取传输资源。
此外,本申请的各个方面或特征可以实现成方法、装置或使用标准编程和/或工程技术的制品。本申请中使用的术语“制品”涵盖可从任何计算机可读器件、载体或介质访问的计算机程序。例如,计算机可读介质可以包括,但不限于:磁存储器件(例如,硬盘、软盘或磁带等),光盘(例如,压缩盘(Compact Disc,CD)、数字通用盘(Digital Versatile Disc,DVD)等),智能卡和闪存器件(例如,可擦写可编程只读存储器(Erasable Programmable Read-Only Memory,EPROM)、卡、棒或钥匙驱动器等)。另外,本文描述的各种存储介质可代表用于存储信息的一个或多个设备和/或其它机器可读介质。术语“机器可读介质”可包括但不限于,能够存储、包含和/或承载指令和/或数据的各种介质。
应理解,本文中术语“系统”和“网络”在本文中常被可互换使用。本文中术语“和/或”,仅仅是一种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这三种情况。另外,本文中字符“/”,一般表示前后关联对象是一种“或”的关系。
