Description

一种通信方法、资源分配方法及装置
本申请要求于2018年09月11日提交国家知识产权局、申请号为201811057265.X、申请名称为“一种通信方法、资源分配方法及装置”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
本申请实施例涉及通信技术领域，尤其涉及一种通信方法、资源分配方法及装置。
背景技术
频谱资源分为授权(Licensed spectrum)频谱和非授权(Unlicensed spectrum)频谱。其中，授权频谱可以让某一些机构或运营商使用。非授权频谱为共享频谱，不同的运营商/机构可以使用。因此，为了公平的使用非授权频谱，终端和接入网设备在发送数据之前，需要执行先听后讲(listen-before-talk，LBT)信道接入过程。如果LBT信道接入过程未完成，则终端和接入网设备不能利用该非授权频谱发送数据。LBT信道接入过程完成，终端和接入网设备可以利用该非授权频谱发送数据。
目前LBT信道接入过程包括：基于固定时长的能量检测和基于回退机制的能量检测。对于基于固定时长的能量检测是指终端或接入网设备确定在固定时长上检测的信号能量低于预设门限，则认为信道空闲，否则终端或接入网设备确定信道忙碌。对于基于回退机制的能力检测，终端和接入网设备从一个范围窗口中，随机选择一个值A，当检测至少A个空闲的基于固定时长的能量检测，则终端或接入网设备确定信道空闲。当信道空闲，数据可以发送，否则，数据不能发送。
目前现有技术中，无论终端是否执行LBT成功，如果接入网设备解析不到终端发送的数据，则接入网设备便向终端发送重传指示，用于指示终端重新发送数据。但是接入网设备并不确定因为什么原因导致终端发送数据失败，此外，现有技术中也并未记载终端如何使用未授权频谱中的传输资源在侧行链路上向另一个终端发送数据。
发明内容
本申请实施例提供一种通信方法、资源分配方法及装置，用以解决终端之间在非授权频谱资源上发送数据的问题。
为了解决上述技术问题，本申请实施例提供如下技术方案：
第一方面，本申请实施例提供一种通信方法，包括：第一终端获取接入网设备发送的用于第一终端在侧行链路上发送数据的第一传输资源的指示信息，侧行链路为第一终端和第二终端之间的无线通信链路，第一传输资源为未授权频谱中的资源。第一终端在未授权频谱上执行信道接入过程。第一终端确定未授权频谱执行信道接入过程出现失败的情况下，第一终端向接入网设备发送第一信息，该第一信息用于请求在未授权频谱中为侧行链路分配第二传输资源。
本申请实施例提供一种通信方法，第一终端通过获取第一传输资源，然后在该第一传输资源所属于的未授权频谱上执行信道接入过程。由于在信道接入过程出现失败的情况下，第一终端将在第一传输资源上无法向第二终端发送数据，因此为了保证第一终端可以和第二终端在未授权频谱上通信，第一终端通过向接入网设备发送第一信 息，以请求接入网设备重新在未授权频谱中为侧行链路分配第二传输资源。这样以便后续第一终端通过所请求到的第二传输资源，在侧行链路上与第二终端发送数据。
一种可能的实现方式中，第二传输资源与未授权频谱的信息关联，或者，第二传输资源与未授权频谱关联的一个或者多个信道(channel)中发生信道接入失败的channel的信息关联。这样便于接入网设备在接收到第一信息之后，明确所请求的第二传输资源是在哪个未授权频谱中的。

5)、重传，是指终端2未成功解析终端1在Sidelink资源上发送的传输块1或者终端1未成功在Sidelink资源上发送传输块1时，重新向终端2发送传输块1。
需要说明的是，本申请实施例中，“示例性的”或者“例如”等词用于表示作例 子、例证或说明。本申请实施例中被描述为“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。
本申请中，“至少一个指一个或者多个。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，为了便于清楚描述本申请实施例的技术方案，在本申请的实施例中，采用了“第一”、“第二”等字样对功能和作用基本相同的相同项或相似项进行区分。本领域技术人员可以理解“第一”、“第二”等字样并不对数量和执行次序进行限定，并且“第一”、“第二”等字样也并不限定一定不同。
本申请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申请实施例的技术方案，并不构成对于本申请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，本申请实施例提供的技术方案对于类似的技术问题，同样适用。
如图1所示，图1示出了本申请实施例提供的一种通信系统示意图，该通信系统包括：一个或者多个接入网设备101，与接入网设备101通信的一个或者多个第一终端102以及与第一终端102通信的第二终端103。
可选的，接入网设备101还可以与第二终端103通信。
其中，接入网设备101与第一终端102和第二终端102之间分别具有第一接口，第一终端102和第二终端103之间具有第二接口。
示例性的，第一接口可以为Uu接口，第二接口可以为PC5接口。
由于部分V2X(其中，X代表任何事物)业务(例如车辆与车辆之间通信(vehicle to vehicle，V2V)或者车辆与路边基础设施通信(vehicle to infrastructure，V2I)(例如，基础设施为路侧单元(road side unit，RSU))或者车辆与行人之间的通信(vehicle to pedestrian，V2P)或者车辆与网络通信(vehicle to network，V2N))通信场景也属于终端和终端直连通信的场景，因此可以通过设备到设备(device to device，D2D)技术来传输V2X业务。但在实际过程中，两个或两个以上的终端(例如，车辆)之间在直连通信时，此时，可以将两个车辆直连通信的接口可以称为PC5接口，采用车联网专用频段(如5.9GHz)，而车辆与接入网设备之间的接口可以称为Uu接口，采用蜂窝网频段(如1.8GHz)。
本申请实施例中将两个终端进行通信的链路称为侧行链路。例如，第一终端102和第二终端103可以在侧行链路上传输V2X业务。
可以理解的是，图1中仅示出的接入网设备、第一终端和第二终端的数量为1个。在实际过程中接入网设备、第一终端和第二终端的数量还可以为两个或者两个以上。当然，该通信系统还可以包括其他网元(例如，核心网设备)。接入网设备可以与该核心网设备连接。核心网设备可以是4G核心网(例如，核心分组网演进(Evolved Packet  Core，EPC))或者5G核心网(5G Core，5GC)中的网元。
此外，图1中以接入网设备101覆盖的小区可以为一个或多个小区为例，本申请对此不做具体限定。
示例性的，如图1所示，接入网设备101覆盖的小区为第一小区。可以理解的是，图1中以一个接入网设备覆盖一个小区为例进行说明。
在本发明实施例中，终端可以分布于无线网络中，每个终端可以是静态的或移动的。
其中，第一终端102和第二终端103可以是同一个小区内的终端，也可以是不同小区内的终端。图1以第一终端102和第二终端103位于第一小区为例，且第一小区为接入网设备101覆盖的小区为例。
图2示出了本申请实施例提供的另一种通信系统。图2所示的通信系统与图1的区别在于：图2中第一终端102和第二终端103位于同一个接入网设备覆盖下的不同小区。例如，图2中接入网设备101覆盖的小区包括第一小区和第二小区，其中，第一终端102所在的小区为第一小区，第二终端103所在的小区为第二小区。
如图3所示，图3示出了本申请实施例提供的又一种通信系统。图3所示的通信系统与图2的区别在于：图3中第一终端102和第二终端103位于不同的小区，且第一终端102和第二终端103所在的小区为不同接入网设备覆盖下的小区。例如，图3中接入网设备101覆盖的小区包括第一小区，第一终端102位于接入网设备101覆盖的第一小区。接入网设备104覆盖的小区包括第三小区，第二终端103位于接入网设备104覆盖的第二小区。接入网设备101和接入网设备104之间通过第一接口通信。
一种可能的实现方式中，图3中接入网设备101可以为主基站，接入网设备104可以为辅基站。
其中，主基站是指终端102在随机接入过程中接入的第一个基站。主基站负责与核心网控制面实体之间建立控制面连接，传输信令消息，以及决定是否为终端102创建辅基站，并为终端102选择辅基站。
辅基站，主基站之外的第二基站，用于为终端102提供额外的无线资源的节点，与核心网控制面实体之间可以没有直接的控制面连接。
另一种可能的实现方式中，图3中接入网设备101和接入网设备104可以为独立的基站。
如图1-图3所示的通信系统可以适用于长期演进(Long term Evolution，LTE)系统，即4G网络中。也可以适用于新空口(New Radio，NR)系统中，即5G网络中或未来的各种通信系统。
由于，图1-图3所示的通信系统适用于不同的网络中，第一接口的名称存在差异，因此下述将分别介绍：
一种示例，当通信系统适用于4G网络中时，接入网设备101和/或接入网设备104为LTE系统中的演进型基站(Evolved Node B，eNB)。例如，第一接口可以为X2接口。
另一种示例，当通信系统适用于5G网络中时，接入网设备101和/或接入网设备104为NR系统中的下一代节点B(The Next Generation Node B，gNB)。例如，第一 接口可以为Xn接口。
又一种示例，在图3所示的通信系统中，当接入网设备101和接入网设备104对应不同的网络制式时，例如，接入网设备101对应的网络制式为NR系统，此时接入网设备101可以为gNB。接入网设备104对应的网络制式为LTE系统，此时接入网设备104可以为eNB。或者接入网设备101为eNB。接入网设备104为gNB。在这种示例中，第一接口为X2接口。
终端(terminal)是一种向用户提供语音和/或数据连通性的设备，例如，具有无线连接功能的手持式设备、车载设备等。终端也可以称为用户设备(User Equipment，UE)、接入终端(Access Terminal)、用户单元(User Unit)、用户站(User Station)、移动站(Mobile Station)、移动台(Mobile)、远方站(Remote Station)、远程终端(Remote Terminal)、移动设备(Mobile Equipment)、用户终端(User Terminal)、无线通信设备(Wireless Telecom Equipment)、用户代理(User Agent)、用户装备(User Equipment)或用户装置。终端可以是无线局域网(Wireless Local Area Networks，WLAN)中的站点(Station，STA)，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)设备、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、可穿戴设备以及下一代通信系统(例如，第五代(Fifth-Generation，5G)通信网络)中的终端或者未来演进的公共陆地移动网络(Public Land Mobile Network，PLMN)网络中的终端等。其中，5G还可以被称为新空口(New Radio，NR)。本申请一种可能的应用的场景中终端为经常工作在地面的终端，例如车载设备。在本申请中，为了便于叙述，部署在上述设备中的芯片，或者芯片也可以称为终端。
作为示例，在本申请实施例中，该终端还可以是可穿戴设备。可穿戴设备也可以称为穿戴式智能设备，是应用穿戴式技术对日常穿戴进行智能化设计、开发出可以穿戴的设备的总称，如眼镜、手套、手表、服饰及鞋等。可穿戴设备即直接穿在身上，或是整合到用户的衣服或配件的一种便携式设备。可穿戴设备不仅仅是一种硬件设备，更是通过软件支持以及数据交互、云端交互来实现强大的功能。广义穿戴式智能设备包括功能全、尺寸大、可不依赖智能手机实现完整或者部分的功能，例如：智能手表或智能眼镜等，以及只专注于某一类应用功能，需要和其它设备如智能手机配合使用，如各类进行体征监测的智能手环、智能首饰等。
接入网设备为与终端配合使用的一种可以用于发射或接收信号的实体。例如，可以是WLAN中的接入点(Access Point，AP)，还可以是LTE中的演进型基站(evolved Node B，eNB或eNodeB)，或者中继站或接入点，或者车载设备、可穿戴设备以及未来5G网络中的接入网设备或者未来演进的PLMN网络中的接入网设备等。
另外，在本发明实施例中，接入网设备为小区提供服务，终端通过该小区使用的传输资源(例如，时域资源，或者，频域资源，或者，时频资源)与接入网设备进行通信。该小区可以是接入网设备(例如基站)对应的小区，小区可以属于宏基站，也可以属于小小区(small cell)对应的基站，这里的小小区可以包括：城市小区(metro cell)、微小区(micro cell)、微微小区(Pico cell)、毫微微小区(femto cell)等， 这些小小区具有覆盖范围小和发射功率低的特点，适用于提供高速率的数据传输服务。
由于未来接入网可以采用云无线接入网(cloud radio access network，C-RAN)架构来实现，一种可能的方式是将传统基站的协议栈架构和功能分割为两部分，一部分称为集中单元(central unit，CU)，另一部分称为分布单元(distributed unit，DU)，而CU和DU的实际部署方式比较灵活，例如多个基站的CU部分集成在一起，组成一个规模较大的功能实体。如图4所示，其为本申请实施例提供的一种网络架构的示意图。如图4所示，该网络架构包括核心网(Core Network，CN)设备和接入网(以无线接入网(Radio Access Network，RAN)为例)设备。其中RAN设备包括基带装置和射频装置，其中基带装置可以由一个节点实现，也可以由多个节点实现，射频装置可以从基带装置拉远独立实现，也可以集成基带装置中，或者部分拉远部分集成在基带装置中。例如，在LTE通信系统中，RAN设备(eNB)包括基带装置和射频装置，其中射频装置可以相对于基带装置拉远布置(例如射频拉远单元(Radio Remote Unit，RRU)相对于基带处理单元(Building Base band Unit，BBU))，RAN设备由一个节点实现，该节点用于实现无线资源控制(Radio Resource Control，RRC)、分组数据汇聚层协议(Packet Date Convergence Protocol，PDCP)、无线链路控制(Radio Link Control，RLC)、媒体接入控制(Medium Access Control，MAC)等协议层的功能。再如，在一种演进结构中，基带装置可以包括集中单元(centralized unit，CU)和分布单元(distributed unit，DU)，多个DU可以由一个CU集中控制。如图4所示，CU和DU可以根据无线网络的协议层划分，例如分组数据汇聚层协议层及以上协议层的功能设置在CU，比如CU具有RRC协议层功能和PDCP协议层功能；PDCP以下的协议层，例如无线链路控制(Radio Link Control，RLC)和媒体接入控制层，以及物理层等功能设置在DU。
这种协议层的划分仅仅是一种举例，还可以在其它协议层划分，例如在RLC层划分，将RLC层及以上协议层的功能设置在CU，RLC层以下协议层的功能设置在DU；或者，在某个协议层中划分，例如将RLC层的部分功能和RLC层以上的协议层的功能设置在CU，将RLC层的剩余功能和RLC层以下的协议层的功能设置在DU。此外，也可以按其它方式划分，例如按时延划分，将处理时间需要满足时延要求的功能设置在DU，不需要满足该时延要求的功能设置在CU。
此外，射频装置可以拉远，不放在DU中，也可以集成在DU中，或者部分拉远部分集成在DU中，在此不作任何限制。
此外，请继续参考图5，相对于图4所示的架构，还可以将CU的控制面(control plane，CP)和用户面(user plane，UP)分离，分成不同实体来实现，分别为控制面CU实体(CU-CP实体)和用户面CU实体(CU-UP实体)。
在以上网络架构中，CU产生的数据可以通过DU发送给终端，或者终端产生的数据可以通过DU发送给CU。DU可以不对该数据进行解析而直接通过协议层封装后传给终端或CU。例如，RRC或PDCP层的数据最终会处理为物理层(Physical Layer，PHY)的数据发送给终端，或者，由接收到的PHY层的数据转变而来。在这种架构下，该RRC或PDCP层的数据，即也可以认为是由DU发送的。
在以上实施例中CU划分为RAN中接入网设备，此外，也可以将CU划分为CN 中的接入网设备，在此不做限制。
本申请以下实施例中的装置，根据其实现的功能，可以位于终端或接入网设备。当采用以上CU-DU的结构时，接入网设备可以为CU节点、或DU节点、或包括CU节点和DU节点功能的RAN设备。
图6是一种接入网设备的结构示意图。接入网设备101或接入网设备104的结构可以参考图6所示的结构。
接入网设备包括一个或者多个处理器1111、一个或者多个收发器1113、一个或者多个网络接口1114和一个或多个天线1115。可选的，接入网设备还可以包括一个或者多个存储器1112。

存储器1112可以是独立存在，与处理器1111相连。可选的，存储器1112也可以和处理器1111集成在一起，例如集成在一个芯片之内。其中，存储器1112能够存储执行本申请实施例的技术方案的程序代码，并由处理器1111来控制执行，被执行的各类计算机程序代码也可被视为是处理器1111的驱动程序。例如，处理器1111用于执行存储器1112中存储的计算机程序代码，从而实现本申请实施例中的技术方案。
收发器1113可以用于支持接入网设备与终端之间射频信号的接收或者发送，收发器1113可以与天线1115相连。收发器1113包括发射机Tx和接收机Rx。具体地，一个或多个天线1115可以接收射频信号，该收发器1113的接收机Rx用于从天线接收射频信号，并将射频信号转换为数字基带信号或数字中频信号，并将该数字基带信号 或数字中频信号提供给处理器1111，以便处理器1111对该数字基带信号或数字中频信号做进一步的处理，例如解调处理和译码处理。此外，收发器1113中的发射机Tx还用于从处理器1111接收经过调制的数字基带信号或数字中频信号，并将该经过调制的数字基带信号或数字中频信号转换为射频信号，并通过一个或多个天线1115发送射频信号。具体地，接收机Rx可以选择性地对射频信号进行一级或多级下混频处理和模数转换处理以得到数字基带信号或数字中频信号，下混频处理和模数转换处理的先后顺序是可调整的。发射机Tx可以选择性地对经过调制的数字基带信号或数字中频信号时进行一级或多级上混频处理和数模转换处理以得到射频信号，上混频处理和数模转换处理的先后顺序是可调整的。数字基带信号和数字中频信号可以统称为数字信号。
如图7所示，为本申请实施例提供的一种终端的结构示意图。终端102或者终端103的结构可以参考图7所示的结构。
终端包括一个或者多个处理器1211、一个或者多个收发器1212和一个或者多个存储器1213。处理器1211、存储器1213和收发器1212相连。可选的，终端121还可以包括输出设备1214、输入设备1215和一个或多个天线1216。天线1216与收发器1212相连，输出设备1214、输入设备1215与处理器1211相连。

本申请实施例中一种通信方法的执行主体可以为第一终端，也可以为应用于第一终端中的通信装置，例如芯片。一种资源分配方法的执行主体可以为接入网设备，也可以为应用于接入网设备中的资源分配装置，例如芯片。下述实施例将以一种资源分配方法的执行主体为接入网设备，一种通信方法的执行主体为第一终端可以为。可以理解的是，下述步骤中，但凡由接入网设备执行的步骤均可以由应用于接入网设备中的芯片执行，但凡由第一终端执行的步骤均可以由应用于第一终端中的芯片执行。
如图8所示，图8示出了本申请实施例提供的一种通信方法和资源分配方法交互的流程示意图，该方法包括：
S101、接入网设备向第一终端发送用于第一终端在侧行链路上发送数据的第一传输资源的指示信息，该侧行链路为第一终端和第二终端之间的无线通信链路，第一传输资源为未授权频谱中的资源。
示例性的，第一传输资源的指示信息用于终端确定第一传输资源。例如，指示信息可以为第一传输资源的标识，例如，索引。或者第一传输资源在未授权频谱中的位置。或者第一传输资源在未授权频谱中的起始位置以及长度。
其中，接入网设备可以通过如下方式向终端发送用于第一终端在侧行链路上发送数据的第一传输资源的指示信息：
小区级半静态配置信息，小区级可以理解为该配置信息中携带的指示信息对小区中的终端有效或者该配置信息可以发送给该小区的终端，半静态可以理解为该配置信息可以通过高层信令下发，该高层信令可以理解为无线资源控制(Radio Resource Control，RRC)层的信令，例如，该高层信令可以是系统消息，接入网设备可以广播系统消息，该系统消息中可以携带小区级半静态配置信息。
用户级半静态配置信息，用户级可以理解为该配置信息中携带的指示信息对特定的终端有效或者该配置信息可以发送给特定终端，半静态可以理解为该配置信息可以通过高层信令下发，高层信令可以理解为无线资源控制(Radio Resource Control，RRC)层的信令，例如该高层信令可以是RRC消息，接入网设备可以向终端发送RRC消息，该RRC消息可以包括终端级半静态配置信息。
用户级动态配置信息，用户级可以理解为该配置信息中携带的指示信息对特定的终端有效或者该配置信息可以发送给特定终端，动态可以理解为该配置信息可以通过物理层信息下发，例如该物理层信令可以是下行控制信息(Downlink Control Information，DCI)，接入网设备可以通过物理下行控制信道(Physical Downlink Control Channel，PDCCH)发送该DCI，该DCI可以包括终端级动态配置信息，这里PDCCH可以是组公共(group common，GC)PDCCH。
其中，第一传输资源可以为mode3资源或mode4资源。其中，mode3资源为接入网设备通过下行控制信道在未授权频谱上为第一终端分配的资源。例如，动态调度的资源，或，半静态调度的资源(无线资源控制(Radio Resource Control，RRC)配置周期，DCI进行激活，周期性的Sidelink资源)。mode 4资源为接入网设备通过RRC信令分配的Sidelink资源，可以是竞争性的资源，通过系统信息广播。也可以非竞争性的资源，通过专用信令通知。
mode 3模式下，第一终端每次发送数据前，都需要向接入网设备申请传输资源，然后在接入网设备分配的传输资源上向第二终端发送业务数据。则此时由于各个终端的传输资源是由接入网设备统一分配的，因此一般不会发生邻近终端被分配到相同资源的情况，因此，mode 3模式可以保证更好的传输可靠性。但是，由于终端每次申请资源时，需要和接入网设备之间交互信令，因此，相对于mode 4模式，采用mode 3模式发送数据的传输时延相对于mode 3可能要长。
在mode 4模式下，终端发送数据时，可以通过随机选择、基于侦听预留机制或基于部分侦听预留机制来自主地从终端SL传输资源池中获取侧行链路通信资源来发送数据。则此时由于各个终端的资源是自主选择的，可以不需要和接入网设备之间交互信令，所以采用mode 4模式发送数据的传输时延相对于mode 3模式可能要短。
S102、第一终端获取接入网设备发送的用于第一终端在侧行链路上发送数据的第一传输资源的指示信息。
S103、第一终端在未授权频谱上执行信道接入过程。
示例性的，第一终端可以在确定满足如下条件时，触发在未授权频谱上执行信道接入过程：
一种可能的实现方式中，第一终端确定有允许通过未授权频谱传输的Sidelink数据到达，触发Sidelink新传时，则触发在未授权频谱上执行信道接入过程。
另一种可能的实现方式中，第一终端确定触发Sidelink重传(包括盲重传，基于反馈的重传)。
其中，信道接入过程是每信道(per channel)的。一个未授权频谱可以包括一个或者多个channel，第一终端选择一个或者多个channel执行信道接入过程。
例如，未授权频谱包括：channel 1、channel 2和channel 3。如果第一终端确定使用channel 1和channel 2发送Sidelink数据，则第一终端针对channel 1做信道接入过程，针对channel 2做信道接入过程。一个channel是固定带宽的频域资源。
本申请实施例中第一终端配置有一个或者多个未授权频谱。该一个或者多个未授权频谱可以为接入网设备为第一终端配置的，也可以是预配置的，本申请实施例对此不作限定。
示例性的，第一传输资源仅为未授权频谱中的部分资源，当第一终端要在第一传输资源上向第二终端发送数据时，第一终端可以在第一传输资源所在的整个未授权频谱上执行信道接入过程。
S104、第一终端确定未授权频谱执行信道接入过程出现失败的情况下，第一终端向接入网设备发送第一信息，该第一信息用于请求在未授权频谱中为侧行链路分配第二传输资源。
示例性的，该第一传输资源/第二传输资源可以为Sidelink资源。
需要说明的是，终端所请求的第二传输资源和第一传输资源可以为终端具有的一个或者多个未授权频谱中同一个未授权频谱中的资源。例如，如图9中的(a)所示，第一传输资源和第二传输资源均为未授权频谱1中的资源。可以理解的是图9中的(a)中以第一传输资源和第二传输资源为未授权频谱1中连续的传输资源为例，当然在实际过程中，第一传输资源和第二传输资源还可以为未授权频谱1中不连续的传输资源。
终端所请求的第二传输资源和第一传输资源可以为终端具有的一个或者多个未授权频谱中不同未授权频谱中的资源。例如，如图9中的(b)所示，第一传输资源为未授权频谱1中的资源。第二传输资源为未授权频谱2中的资源。可以理解的是图9中的(b)中以未授权频谱1和未授权频谱2为连续的未授权频谱为例，当然在实际过程中，未授权频谱1和未授权频谱2还可以为不连续的未授权频谱。
第一终端确定未授权频谱出现信道接入过程失败可以通过以下任一方式实现：
方式1，第一终端确定未授权频谱包括的一个或者多个channel中存在一个或者多个channel的信道接入过程失败，则第一终端确定未授权频谱出现信道接入过程失败。
具体的，第一终端可以确定发生信道接入过程失败的channel的数量，也可以由接入网设备为终端配置发生信道接入过程失败的channel的数量，本申请实施例对此不作限定。
方式2，由于第一终端可能配置有周期性的第一传输资源，每个第一传输资源之 前可能都需要进行信道接入过程。因此，第一终端确定未授权频谱包括的一个或者多个channel中存在一个channel的信道接入过程失败次数大于第一阈值，则第一终端确定未授权频谱出现信道接入过程失败。
本申请实施例对第一阈值不作限定。该第一阈值可以是第一终端自己决定的，也可以是接入网设备为第一终端指定的，也可以是预配置的。
可以理解的是，本申请实施例中未授权频谱包括一个或者多个未授权频谱。该一个或者多个未授权频谱可以是接入网设备为第一终端配置的，也可以是预配置的。
未授权频谱包括一个或者多个channel的数量可以是接入网设备配置的，第一终端可以从一个或者多个channel中决定哪些或者哪个channel的信道接入过程失败次数大于第一阈值，则第一终端确定未授权频谱出现信道接入过程失败。
第一终端在未授权频谱上判断channel的信道接入过程失败的条件如下任意一种：
a)、在第一传输资源的上行传输的起始时域位置之前，第一终端的信道接入过程未完成。
b)、在第一传输资源的上行传输的所有的起始时域位置之前，第一终端的信道接入过程未完成。
示例性的，第一传输资源在时域上一个时隙(slot)有三个起始时域位置：A，B和C。则对于a)而言，若终端确定在起始时域位置A之前，第一终端的信道接入过程未完成则第一终端的信道接入过程未完成确定未授权频谱上channel的信道接入过程失败。对于b)而言，若终端确定在起始时域位置A、B以及C之前，第一终端的信道接入过程未完成则第一终端的信道接入过程未完成确定未授权频谱上channel的信道接入过程失败。
c)、如果在未授权频谱配置了重复发送，第一终端在所有重复发送对应的资源的上行传输起始位置之前都没有完成信道接入过程。
为了使得接入网设备确定第二传输资源是为哪个未授权频谱分配的，因此，第一终端可以通过如下方式处理第一信息：
一种示例，第一信息中请求的第二传输资源与未授权频谱的信息关联。这样便于接入网设备在第一传输资源所属的未授权频谱中为第一终端分配第二传输资源。
具体的，本申请实施例中每个传输资源其所属的未授权频谱关联，传输资源其所属的未授权频谱关联指传输资源的信息与未授权频谱的信息关联。例如，第二传输资源的标识与未授权频谱的标识关联。
一种可能的实现方式中，该传输资源其所属的未授权频谱之间的关联可以是接入网设备配置的，如果第一终端确定未授权频谱出现信道接入过程失败的情况下，第一终端在第一信息中携带与未授权频谱的信息存在关联的信息。
示例性的，未授权频谱的信息用于识别未授权频谱。例如，可以为未授权频谱的索引。
例如，未授权频谱1与索引1关联，则第一终端在第一信息中携带索引1。这样接入网设备在接收到的第一信息后，便可以确定未授权频谱1出现信道接入过程失败的情况。
另一种可能的实现方式中，步骤S104可以通过以下方式实现：第一终端使用第一 传输资源对应的通信资源向接入网设备发送第一信息。
可以理解的是，本申请实施例中第一终端中具有一个或者多个通信资源中每个通信资源对应的传输资源。其中，一个或者多个通信资源用于第一终端在与接入网设备之间的传输链路上向接入网设备发送信息。例如，通信资源可以为Uu资源。
其中，第一终端中具有一个或者多个通信资源中每个通信资源对应的传输资源可以是预配置的，也可以是接入网设备配置的。
在为接入网设备配置的情况下，一种可能的实现方式，在S104之前，本申请实施例提供的方法还包括：接入网设备向第一终端发送未授权频谱与一个或者多个通信资源之间的关联关系。该第一终端获取未授权频谱与一个或者多个通信资源之间的关联关系，该关联关系用于表示未授权频谱与一个或者多个通信资源对应。
或者，又一种可能的实现方式，在S104之前，本申请实施例提供的方法还包括：接入网设备向第一终端发送未授权频谱包括的一个或者多个channel中每个channel与通信资源之间的关联关系，该第一终端获取未授权频谱包括的一个或者多个channel中每个channel与通信资源之间的关联关系。该关联关系用于表示每个channel对应的通信资源。
其中，接入网设备向终端发送关联关系的目的在于，当一个未授权频谱上出现信道接入过程失败或者信道出现信道接入失败时，第一终端可以利用与该未授权频谱/信道具有关联的通信资源在与接入网设备之间的传输链路上向接入网设备发送第一信息。以便接入网设备确定哪个未授权频谱出现信道接入过程失败。
如图10所示，第一终端确定通信资源1与未授权频谱1的信息具有关联关系，通信资源2与未授权频谱2的信息具有关联关系。例如，如果第一终端确定未授权频谱1出现信道接入过程失败的情况下，第一终端可以在通信资源1上向接入网设备发送第一信息。这样如果接入网设备在通信资源1上接收到第一信息，便可以确定与通信资源1关联的未授权频谱1出现信道接入过程失败。
另一种示例，第一信息中请求的第二传输资源与发生信道接入失败的channel的信息关联。
一种可能的实现方式中，该关联可以是接入网设备配置的，如果终端确定未授权频谱出现信道接入过程失败，终端在第一信息中携带与发生信道接入失败的channel的信息关联信息。
示例性的，channel的信息用于识别channel。例如，可以是channel的索引或者标识信息。
另一种可能的实现方式中，步骤S104可以通过以下方式实现：第一终端使用未授权频谱中出现信道接入失败的channel关联的资源向接入网设备发送第一信息。
如图11所示，第一终端确定通信资源1与未授权频谱1的信息之间具有关联关系，channel 1为未授权频谱1中的channel。通信资源2与未授权频谱2的信息之间具有关联关系，channel 2为未授权频谱2中的channel。通信资源3与未授权频谱3的信息关联，channel 3为未授权频谱3中的channel。例如，如果第一终端确定未授权频谱2出现信道接入过程失败，则第一终端可以在通信资源2上向接入网设备发送第一信息。这样接入网设备在接收到第一信息后，便可以确定与通信资源1关联的未授权频谱1 出现信道接入过程失败。
又一种示例，第一终端可以在第一信息中携带发生信道接入失败的channel的信息和未授权频谱的信息中的至少一项。
示例性的，如果第一终端以方式2确定未授权频谱出现信道接入过程失败，则该第一信息可以以测量报告的形式发送给接入网设备。
此外，如果第一信息中携带发生信道接入失败的channel的信息和未授权频谱的信息中的至少一项或者与发生信道接入失败的channel的信息和未授权频谱的信息中的至少一项关联的信息时，第一终端可以在与信道关联的资源或者与第一传输资源对应的通信资源上发送该第一信息。第一终端也可以在其他资源上向接入网设备发送该第一信息。当第一终端在其他资源上发送该第一信息时，第一终端需要在发送第一信息前向接入网设备请求其他资源。第一终端向接入网设备请求其他资源的具体实现方式，可以参考现有技术中的描述，此处不再赘述。
S105、接入网设备接收第一信息。
一种示例，接入网设备在与未授权频谱或者发生信道接入失败的信道关联的通信资源上接收第一信息。
另一示例，如果第一终端在S104之前向接入网设备请求其他资源，则接入网设备在第一终端所请求的其他资源上接收第一信息。
接入网设备接收到的第一信息的内容可以参考第一终端发送的第一信息的内容，此处不再赘述。可以理解的是，第一终端以哪种方式发送第一信息，接入网设备便以对应的方式接收第一信息。
S106、接入网设备根据第一信息，在未授权频谱中为第一终端的侧行链路分配第二传输资源。
示例性的，在接入网设备根据第一信息确定未授权频谱出现信道接入失败的情况时，接入网设备为第一终端分配的第二传输资源和第一传输资源在频域上可以相同。也可以不相同。如上第二传输资源可以和第一传输资源是同一个未授权频谱中的资源，也可以是不同未授权频谱中的资源。
本申请实施例提供一种通信方法，第一终端通过获取第一传输资源，然后在该第一传输资源所属于的未授权频谱上执行信道接入过程。由于在信道接入过程出现失败的情况下，第一终端将在第一传输资源上无法向第二终端发送数据，因此为了保证第一终端可以和第二终端在未授权频谱上通信，第一终端通过向接入网设备发送第一信息，以请求接入网设备重新在未授权频谱中为侧行链路分配第二传输资源。这样以便后续第一终端通过所请求到的第二传输资源，在侧行链路上与第二终端发送数据。
一种可能的实现方式中，S106可以通过以下方式实现：接入网设备根据第一信息，确定未授权频谱执行信道接入过程出现失败的情况下，接入网设备在未授权频谱中为第一终端的侧行链路分配第二传输资源。
接入网设备可以通过如下中任一或任几种方式确定未授权频谱执行信道接入过程出现失败：
方式A、以第二传输资源与未授权频谱的信息关联为例：
接入网设备确定第二传输资源与未授权频谱的信息关联，接入网设备根据与未授 权频谱的信息关联的信息，确定未授权频谱的信息指示的未授权频谱出现信道接入过程失败。
一种可能的实现方式中，接入网设备确定在第一传输资源对应的通信资源上接收到第一信息，接入网设备确定未授权频谱出现信道接入过程失败。
方式B、第二传输资源与出现信道接入过程失败的channel的信息关联为例：
接入网设备确定第二传输资源与出现信道接入过程失败的channel的信息关联，接入网设备根据与出现信道接入过程失败的channel的信息关联的信息，确定出现信道接入过程失败的channel的信息关联的未授权频谱出现信道接入过程失败。
一种可能的实现方式中，接入网设备确定在第一channel关联的资源上接收到第一信息，接入网设备确定第一channel关联的未授权频谱出现信道接入过程失败。
方式C、第一信息包括：未授权频谱的信息和出现信道接入过程失败的channel的信息中的至少一项。接入网设备根据未授权频谱的信息和出现信道接入过程失败的channel的信息中的至少一项，确定未授权频谱出现信道接入过程失败。
一种可能的实现方式中，接入网设备根据未授权频谱的信息，确定未授权频谱的信息指示的未授权频谱出现信道接入过程失败。
一种可能的实现方式中，接入网设备根据出现信道接入过程失败的channel的信息，确定出现信道接入过程失败的channel的信息指示的channel所在的未授权频谱出现信道接入过程失败。
作为本申请的另一个实施例，本申请实施例提供的方法还包括：第一终端确定未授权频谱发生信道接入过程成功时，第一终端向接入网设备发送用于指示接入成功的消息。此时接入网设备在接收到用于指示接入成功的消息时，可以为第一终端分配用于新传的传输资源。这样第一终端便可以在用于新传的传输资源发送下一个传输块。具体的，第一终端向接入网设备发送用于指示接入成功的消息的方式可以参考第一终端向接入网设备发送第一信息的方式。
可以理解的是，当第一终端确定未授权频谱发生信道接入过程成功时，第一终端便可以在第一传输资源上向第二终端发送数据。
当接入网设备在接收到用于指示接入失败的第一信息时，可以为第一终端分配用于重传的第二传输资源，这样第一终端便可以在第二传输资源上重新传输被解析失败的传输块。
由于不同业务信息对信道的要求不同。例如，有的业务需要低时延，有的业务需要高可靠性传输。而上述S103-S106中虽然描述了第一终端要执行信道接入过程，但没有指出第一终端在执行信道接入过程时，使用什么样的信道接入过程的参数。因此，作为本申请的另一个实施例，如图12所示，本申请实施例提供的方法还包括：
S107、第一终端获取信道接入优先等级(channel access priority class)。
一种可能的实现方式中，S107具体可以通过以下方式实现：第一终端接收接入网设备发送的信道接入优先等级。
又一种可能的实现方式中，S107具体可以通过以下方式实现：第一终端根据第一传输资源上传输的数据的业务信息，以及映射关系，获取信道接入优先等级。其中，映射关系包括一个或者多个业务信息和一个或者多个业务信息中每个业务信息对应的 信道接入优先等级，不同信道接入优先等级对应不同的信道接入参数。
示例性的，第一终端根据该Sidelink资源进行媒体接入控制协议数据单元(Medium access control protocol data unit，MAC PDU)的构造，根据Sidelink资源的MAC PDU中包括数据的业务信息，确定信道接入优先等级。
可以理解的是，第一终端具有一个或者多个业务信息与一个或者多个信道接入优先等级的映射关系。该映射关系可以是预配置的，也可以由接入网设备为第一终端配置的。
示例性的，业务信息包括以下一项或多项：时延量化参数(ProSe Per-Packet Priority，PPPP)、可靠性量化参数(ProSe Per-Packet reliability，PPPR)、逻辑信道组(Logic Channel Group，LCG)以及服务质量流的标识(QoS flow identifier，QFI)。
例如，PPPP可以为1ms，3ms，20ms。PPPR可以为90％，99％，99.999％。
QFI用于标识一个QoS flow(QoS流)，QoS flow是一种细粒度的QoS区分机制，一个QoS flow具有相同的QoS参数，QoS参数包括以下参数中的任意一种或多种：
1、资源类型(resource type)：资源类型包括：保证比特率(Guaranteed Bit Rate，GBR)、非保证比特率(non-GBR)、低时延保证比特率(Delay critical GBR)。其中，GBR用于指示一个QoS flow的保证传输资源。资源类型用于确定专用的网络资源相关的QoS流量级别的保证流量比特率(GFBR)值是否永久分配。
2、优先级(priority level)，用于指示不同QoS flow之间的调度优先级，高优先级的QoS flow优先保证调度，与5G QoS特性关联的优先级用于指示在QoS流中调度资源的优先级。
3、包的时延预算(Packet Delay Budget，PDB)，PDB定义了数据包在终端和终止N6接口的用户面实体(UPFUser Plane Function，UPF)之间的时延的上限。
4、丢包率(Packet Error Rate，PER)，PER定了协议数据单元(Protocol Data Unit，PDU)(例如IP数据包)的速率丢包的比例上限，该PDU可以为已经有链路层的发送方已发送但未成功处理接收的数据包。
5、平均窗口(Averaging window)，平均窗口仅为GBR QoS flow定义，平均窗口表示保证流比特率(Guaranteed Flow Bit Rate，GFBR)和最大流比特率(Maximum Flow Bit Rate，MFBR)将被计算的持续时间。
6、最大数据突发量(Maximum Data Burst Volume，MDBV)，MDBV仅用于延迟严重低时延的GBR资源类型，MDBV表示5G接入网(5G Access Network，5G-AN)在5G-AN PDB(即5G-AN部分PDB)期间需要服务的最大数据量。
下面以PPPR为例，如图13所示：每一个PPPR或PPPP关联一个channel access priority class。
一种可能的实现方式中，在第一终端确定信道接入优先等级后，S103可以通过以下方式具体实现：第一终端根据信道接入优先等级对应的信道接入参数，在未授权频谱上执行信道接入过程。
可以理解的是，每个信道接入优先等级对应一组信道接入参数。不同的信道接入优先等级可以对应不同的信道接入参数。
例如，MAC PDU可能包括一个或者多个业务信息对应的数据，第一终端从一个 或者多个业务信息对应的信道接入优先等级，确定一个目标优先等级。比如，可靠性要求最高/最低的PPPR，时延要求最短/最长的PPPP，优先级最高/最低的LCG，对应的信道接入优先等级为目标信道接入优先等级。
可选的，本申请实施例提供的方法还包括：接入网设备向第一终端发送用于第一终端在传输链路上发送信息的第一通信资源，传输链路为第一终端和接入网设备之间的无线通信链路，第一通信资源与执行信道接入过程出现失败的未授权频谱关联或者与执行信道接入过程出现失败的信道关联。第一终端获取接入网设备发送的用于第一终端在传输链路上发送信息的第一通信资源，传输链路为第一终端和接入网设备之间的无线通信链路，第一通信资源与执行信道接入过程出现失败的未授权频谱关联或者与执行信道接入过程出现失败的信道关联。
示例性的，第一通信资源为Uu资源。这样便于当某个未授权频谱或者信道执行信道接入过程出现失败时，接入网设备为出现失败的未授权频谱或者信道重新分配Uu资源。
如图14所示，图14示出了本申请提供的另一个通信方法和资源分配方法的流程示意图，该方法包括：
S201、接入网设备向第一终端发送用于第一终端在侧行链路上发送数据的第一传输资源的指示信息，该侧行链路为第一终端和第二终端之间的无线通信链路，第一传输资源为未授权频谱中的资源。
具体的，S201的实现方式可以参考S101处的描述，此处不再赘述。
S202、第一终端获取接入网设备发送的用于第一终端在侧行链路上发送数据的第一传输资源。
S203、第一终端在侧行链路上使用第一传输资源向第二终端发送数据。
S204、第一终端确定第二终端未成功解析第一终端在第一传输资源上发送的传输块。
一种可能的实现方式中，S204可以通过以下方式实现：第一终端接收第二终端发送的混合自动重传请求(Hybrid Automatic Repeat Request，HARQ)消息，该HARQ消息包括以下一项或者多项：第一终端的标识信息，HARQ进程标识信息、载波的标识信息或传输块大小信息，该第一终端根据HARQ消息，确定第二终端未成功解析第一终端在第一传输资源上发送的传输块。
例如，第一终端的标识信息可以用于在终端在随机接入过程所接入的小区中识别该第一终端。例如，第一标识可以为小区无线网络临时标识(Cell Radio Network Temporary Identifier，C-RNTI)。
当然，第一终端还可以通过其他方式确定第二终端未成功解析第一终端在第一传输资源上发送的传输块。
例如，第一终端未在指定时间内接收到第二终端发送的确认字符(Acknowledgement，ACK)，则第一终端确定第二终端未成功解析第一终端在第一传输资源上发送的传输块。
S205、第一终端向接入网设备发送第一信息，该第一信息用于请求重新分配第一传输资源。
S206、接入网设备获取第一信息。
一种可能的实现方式中，接入网设备获取到的第一信息由第一终端发送。
另一种可能的实现方式中，S206可以通过以下方式实现：第二终端确定未成功解析第一终端在第一传输资源上发送的传输块，第二终端向接入网设备发送第一信息。因此，S206可以通过以下方式实现：接入网设备从第二终端处获取第一信息。
示例性的，第二终端向接入网设备发送的第一信息可以为HARQ消息，该HARQ消息用于为第一终端重新分配第一传输资源。该第一传输资源用于重传。其中，HARQ消息包括：第一终端的标识信息、HARQ进程标识信息、载波的标识信息或传输块大小信息。
可选的，当接入网设备可以从第二终端处获取第一信息时，上述S204和S205可以省略。
示例1：当第一终端和第二终端所在的小区均为接入网设备覆盖下的小区时，如图1和图2所示的场景中，HARQ消息包括：V2X HARQ ID(HARQ进程标识)和HARQ反馈信息(feedback information)。第二终端可以通过bitmap的方式反馈多个Sidelink HARQ ID的HARQ feedback。
每个bit位关联一个HARQ ID，例如，bit为1表示确认字符(Acknowledgement，ACK)，bit为0表示否定应答(Negative Acknowledgement，NACK)。
一种示例(1-1)，HARQ消息还可以包括：目的层2标识信息(Destination Layer-2ID information)，业务的标识信息或接收方终端的标识信息(例如，第二终端的标识信息)。
一种示例(1-2)，HARQ消息还可以包括：源(Source)ID information，发送方终端的标识信息(例如，Source ID为第一终端的标识信息)。
一种示例(1-3)，HARQ消息还可以包括：第一终端所在的服务小区的小区标识信息，以便接入网设备根据该标识信息决定通过那个小区发送V2X HARQ feedback information。
一种示例(1-4)，HARQ消息还可以包括：第一终端的标识信息。比如C-RNRI，以便接入网设备根据该标识信息决定给那个终端发送V2X HARQ feedback information。
一种示例(1-5)，HARQ消息还可以包括：剩余时间信息指示。接入网设备可以根据剩余时间信息，决定是否转发V2X feedback information给第一终端。
示例2：当第一终端和第二终端所在的小区为不同接入网设备覆盖下的小区时，如图3所示的场景，该HARQ消息包括以下一项或者多项：
HARQ feedback、V2X HARQ ID或HARQ feedback information。第二终端可以通过bitmap的方式反馈多个Sidelink HARQ ID的HARQ feedback。
每个bit位关联一个HARQ ID，bit为1(ACK)，bit为0(NACK)。
可以理解的是，在示例2中，HARQ消息还可以包括如上述示例(1-1)至示例(1-5)描述的内容。
一种可能的实现方式中，在图3场景下，第二终端先将HARQ消息发送给第二终端所属的接入网设备。然后由第二终端所属的接入网设备将HARQ消息发送给接入网设备。例如，第二终端先将HARQ消息发送给接入网设备104，再由接入网设备104 通过第一接口将HARQ消息发送给接入网设备101。
S207、接入网设备根据第一信息，在未授权频谱中为第一终端的侧行链路分配第二传输资源。
可以理解的是，SS201-S207描述的是第一终端确定第二终端未成功解析传输块的情况。当第一终端确定第二终端成功解析传输块时，第一终端也可以向接入网设备发送第二信息，该第二信息用于请求为第一终端在侧行链路上分配第二传输资源。该第二传输资源用于新传。或者，在第二终端成功解析传输块的情况下，第二终端向接入网设备发送第二信息。
本申请实施例提供一种通信方法，该方法通过第一终端确定第二终端未成功解析第一终端使用未授权频谱上的第一传输资源发送的数据时，向接入网设备发送第一信息，以请求接入网设备为第一终端重新分配第一传输资源，供第一终端重新向第二终端发送数据进行重传。这样不仅可以使用第一终端和第二终端使用未授权频谱，且在传输失败时，可以及时通知接入网设备，以便接入网设备为第一终端重新分配传输资源。
