本申请基于申请号为201710120861.7、申请日为2017年03月02日的中国专利申请提出，并要求该中国专利申请的优先权，该中国专利申请的全部内容在此引入本申请作为参考。
技术领域
本申请涉及车联网技术领域，尤其涉及一种无线资源配置的方法、装置和存储介质。
背景技术
随着经济社会高速发展，道路交通安全问题已经成为影响社会和谐和改善民生的基本问题之一。
基于通信的碰撞预警系统，通过利用先进的无线通信技术和新一代信息处理技术，实现车与车、车与路侧基础设施间的实时信息交互，告知彼此目前的状态(包括车辆的位置、速度、加速度、行驶路径)及获知的道路环境信息，协作感知道路危险状况，及时提供多种碰撞预警信息，防止道路交通安全事故的发生，成为当前解决道路交通安全问题的一种新的思路。
车联网(V2X，Vehicle to Everything)：是指通过装载在车辆上的传感器、车载终端及电子标签提供车辆信息，采用各种通信技术实现车与车(V2V，Vehicle to Vehicle)、车与人(V2P，Vehicle to Pedestrian)、车与路(基础设施)(V2I，Vehicle to Infrastructure)互连互通，并在信息网络平台上对信息进行提取、共享等有效利用，对车辆进行有效的管控和提供综合服务。如图1示出了车联网的基本架构。

具体实施方式
为使本申请的目的、技术方案和优点更加清楚明白，下文中将结合附 图对本申请的实施例进行详细说明。需要说明的是，在不冲突的情况下，本申请中的实施例及实施例中的特征可以相互任意组合。
在附图的流程图示出的步骤可以在诸如一组计算机可执行指令的计算机系统中执行。并且，虽然在流程图中示出了逻辑顺序，但是在某些情况下，可以以不同于此处的顺序执行所示出或描述的步骤。
目前有两种车联网实现技术：专用短距离通信(DSRC，Dedicated Short Range Communication)和长期演进(LTE，Long Time Evolution)，其中DSRC基于IEEE802.11P和IEEE1609系列标准，802.11P负责物理层和媒体接入控制(MAC，Medium Access Control)技术，1609负责上层规范。基于LTE的V2X技术目前还没有标准。第三代合作伙伴计划(3GPP，3rd Generation Partnership Project)正在讨论的LTE V2X技术包括：路边通信单元(RSU，Road Side Unit)可通过静止的用户设备(UE，User Equipment)或演进的节点B/基站(eNB，evolved Node B)实现，V2V/V2I/V2P可能通过PC5接口或Uu接口实现，其中，PC5接口是指设备到设备(D2D，Device to Device)的空中接口，Uu接口是指UE到eNB的空中接口，通过PC5接口传输V2X业务的系统架构如图2所示。
在3GPP正在研究的LTE V2X技术中，针对UE自主选择资源(模式4-mode4)方式中，UE采用感知(sensing)方式选择所需的PC5接口发送资源；当发生切换(HO-Handover)、无线链路失败(RLF，Radio Link Failure)、改变资源池等情况时，可采用异常(exceptional)资源池。对于V2P中的行人(P，Pedestrian)一般不具备PC5接收的能力，即无法采用感知方式选择资源。
V2X信息为安全相关信息，一般不允许丢弃。如果发生网络拥塞，需要针对不同的拥塞程度选择相应的无线资源参数，也就是说，V2X中UE需要根据CBR选择无线资源参数。
V2X中，P-UE不具备PC5接收能力或由于时延限制无法完成测量等情况下，UE将无法测量CBR。UE无法确定无线资源参数将会直接导致V2X业务数据无法正常传输。因此，无法测量CBR或者减轻CBR测量负载时UE如何选择无线资源参数是一个亟待解决的问题。因此，在无法测量CBR或减轻CBR测量负载时如何选择无线资源参数，是解决V2X业务数据正常传输必须首先要解决的技术问题。
为了便于描述，本文中V-UE是指车辆用户设备(Vehicle-UE)，P-UE是指行人用户设备(Pedestrian-UE)。
如图3所示，本申请提供一种无线资源配置的方法，应用于UE，可包括：
步骤301，获取拥塞控制相关信息；
步骤302，根据所述拥塞控制相关信息，确定PC5接口发送资源池的无线资源参数；
步骤303，按照所述无线资源参数在PC5接口发送车联网业务数据。
本申请中，UE可以根据eNB/UE提供的拥塞控制相关信息或预配置数据选择无线资源参数，使得UE在不具备CBR测量能力时、无法测量CBR时、或减轻CBR测量负载时能够选择PC接口发送资源池的无线资源参数，从而确保UE的V2X业务正常进行，实现了PC5接口资源的拥塞控制。
在一些实现方式中，步骤301中获取拥塞控制相关信息可以采用如下之一的方式：接收来自基站eNB的所述拥塞控制相关信息；接收来自其他UE的所述拥塞控制相关信息；读取预配置数据中的拥塞控制相关信息。实际应用中，所述其他UE可以为所述UE邻近区域的UE。所述预配置数据可以为预配置在UE中的拥塞控制相关信息。
在一些实现方式中，步骤301中可以从如下之一中获取拥塞控制相关 信息：Uu接口信令；PC5接口信令；预配置数据。实际应用中，所述Uu接口信令为系统消息或专用RRC信令。
实际应用中，UE可以通过Uu接口信令或PC5接口信令或预配置数据获取拥塞控制相关信息，并根据拥塞控制相关信息确定PC5接口发送资源池的无线资源参数，或者从拥塞控制相关信息中直接提取PC5接口发送资源池的无线资源参数。实际应用中，由于V2X中不同业务有不同的优先级(如紧急刹车业务的PPPP较高，而周期性的位置报告PPPP较低等)，因此，为了适应V2X业务的不同应用场景，可以在确定PC5接口发送资源池的无线资源参数时在拥塞控制相关信息的基础上结合V2X业务优先级(例如，针对临近区域业务(ProSe，Proximity-based Services)，可以是ProSe业务分组优先级(PPPP,ProSe Services Per-Packet Priority))进行选择。
其中，所述通过Uu接口信令或PC5接口信令或预配置数据获取是指：UE获取具体的数值，不需要测量相关的资源池。所述通过Uu接口获取是指通过eNB发送的信息获取，通过PC5接口信令获取是指通过临近的其他UE发送的信息获取，所述预配置数据是指事先保存在UE内部的拥塞控制相关信息。所述UE根据网络侧eNB提供的对照表查找所需的无线资源参数；所述无线资源参数包括以下一种或多种：最大发射功率，数据块重传次数，数据资源块数，调制和编码方案(MCS，Modulation and Coding Scheme)范围，信道占用率限制；其中信道占用率是指：在一个时间段(如1000ms)内，UE用于发送的子信道数除以全部可用的子信道数。所述PPPP为V2X业务的优先级，由上层信息提供；每个PPPP对应一个对照表，表中包含CBR及其对应的无线资源参数，对照表由eNB提供，具体通过RRC信令指示，如果UE处于eNB覆盖范围外，则对照表保存在UE中，如预配置在UE的内存或通用集成电路卡(UICC，Universal Integrated Circuit Card)中。
本申请中，所述拥塞控制相关信息可以包括如下之一：CBR数值；索引值；部分无线资源参数；全部无线资源参数。实际应用中，拥塞控制相关信息可以是CBR相关信息，也可以是其他与V2X业务的拥塞控制相关的信息。其中，CBR数值为具体的数值，如一段时间内子信道能量超过门限值的比值；无线资源参数，包括以下之一：最大发射功率，数据块重传次数，数据资源块数，MCS范围，信道占用率限制。实际应用中，CBR定义为在一段时间(一般为100ms)内，资源池中子信道能量超过门限值的比例，其中子信道能量采用边路-接收信号强度指示(S-RSSI，Sidelink-Received Signal Strength Indication)标识，门限值为事先确定。
相应的，步骤302中根据所述拥塞控制相关信息，确定PC5接口发送资源池的无线资源参数，可以包括如下之一：根据所述CBR值从对照表中查询到所述PC5接口发送资源池的无线资源参数；根据所述索引值从对照表中查询到所述PC5接口发送资源池的无线资源参数；根据所述部分无线资源参数从对照表中查询到所述PC5接口发送资源池的无线资源参数；从所述全部无线资源参数中查询到所述PC5接口发送资源池的无线资源参数。
实际应用中，所述无线资源参数可以包括如下之一或其任意组合：最大发射功率；数据块重传次数；数据资源块数；调制和编码方案MCS范围；信道占用率限制。
实际应用中，针对某个给定的CBR，网络侧可以基于每个V2X业务的优先级(PPPP)提供一个映射表，每个表中包含CBR(一般为一个范围)和对应的无线资源参数，UE可以根据CBR数值从该映射表中选择对应的无线资源参数。
实际应用中，eNB可以为UE提供上述全部的参数或者部分参数，如果发送部分参数，则UE可根据获取的部分参数查找对照表获取其他的参 数。对照表索引值，针对每个PPPP对应的对照表，对照表中可以根据CBR的升序或降序排列。下表1为对照表的示例，表1中以升序为例：
表1：CBR对照表示例
Figure PCTCN2017107353-appb-000001
表1中P表示最大发射功率，N1表示数据块重传次数，N2表示数据资源块数，N3表示MCS，CR表示信道占用率限制。不同索引值对应的无线资源参数不同，UE可根据无线资源参数中一个或多个确定其全部参数。
本申请中，UE获取的拥塞控制相关信息是针对V2X的发送资源池，所述发送资源池可以包括PC5通信异常资源池等。其中，所述PC5通信异常资源池是指用于PC5接口通信的、在发生异常事件(如HO，RLF，资源池更新等)时可临时使用的资源池。PC5通信异常资源池可以由eNB配置(如UE在覆盖内时)或预配置，预配置的PC5通信异常资源池一般保存在UE的内存或UICC中。
所述PC5通信异常资源池可以包括：时域资源信息和频域资源信息。其中，时域资源信息以子帧为单位，频域资源信息以资源块(RB，Resource Block)或子信道(sub channel)为单位，子信道为连续的多个RB。所述PC5通信异常资源池可用于物理边路控制信道(PSCCH，Physical Sidelink Control Channel)、物理边路共享信道(PSSCH，Physical Sidelink Shared  Channel)中之一或两者。
所述PC5通信异常资源池针对mode4的V2X通信，即UE自主选择PC5通信资源，eNB配置的异常资源池可以通过系统消息或专用的无线资源控制(RRC，Radio Resource Control)信令指示。

图7所示方法及其对应的无线资源配置的装置，实现细节可参照图3所示方法的相关记载，不再赘述。
如图9所示，本申请中无线资源配置的具体实现过程可以包括如下步骤：
步骤901：eNB配置上报CBR的UE。
所述配置包括以下内容：CBR的测量目标，CBR的测量配置，CBR测量门限(S-RSSI大小)，需要上报的UE；
可选地，所述配置通过以下至少一种发送：系统广播消息，专用RRC信令；
可选地，具有CBR测量能力的UE都会根据eNB的指示进行CBR测量，但是不需要上述UE都上报得到CBR给eNB，原因是：一方面，如果UE位于eNB的覆盖范围外，则无法上报；另一方面，为了减少上行空口负载，只需要选定的UE上报CBR即可。所述eNB可根据以下之一选择需要上报CBR的UE：UE的能力、UE的V2X兴趣、V2X发送资源池、UE选择PC5资源的方式、UE所在区域、Uu接口上行资源配置、PC5接口资源等，例如，当UE具有PC5接收能力，和/或UE对特定的V2X载频感兴趣，和/或UE采用特定的发送资源池(如例外exceptional pool)，和/或UE采用随机选择或部分感知选择PC5资源，和/或UE处于十字路口，和/或UE的Uu上行资源和PC5资源共享等时，eNB可选择上述场景下的UE上报CBR。
可选地，eNB可指定上报CBR的条件，如：当CBR高于某个门限(拥塞)，或者CBR低于某个门限(轻载)时，上报。
步骤902：eNB判断是否采用系统消息发送CBR相关信息，如果是，转向步骤903，否则转向步骤904。
可选地，所述CBR相关信息包括以下之一：CBR数值，无线资源参数，索引值；其中，CBR数值是指可选地CBR值，如对应的某个整数值，PC5无线资源参数包括以下之一：全部的无线资源参数，部分无线资源参数；索引值是指CBR在对照表中的位置，如表1中的索引值0，1，...，15等。
对于未知的上报UE，所述eNB选择采用系统消息(如SIB21)发送CBR相关信息，对于已知的上报UE，所述eNB选择采用专用RRC消息(如RRCConnectionReconfiguration)发送CBR相关信息，另外，所述eNB可同时采用系统消息和专用RRC信令发送CBR相关信息。实际应用中，可以设置专用RRC信令比系统消息的优先级更高，即UE同时收到系统消息和专用RRC信令，则以专用RRC信令的内容为准。
步骤903：UE通过系统消息获取CBR相关信息。
所述UE接收V2X系统消息，获取CBR相关信息，所述UE为RRC-Idle，或RRC-Connected模式，所述UE在eNB覆盖内。
步骤904：UE通过专用RRC信令获取CBR相关信息。
所述UE接收专用RRC信令得到CBR相关信息，所述UE为RRC-Connected，所述UE在eNB覆盖内。可选地，所述UE可以先向eNB发送CBR请求消息，eNB向所述UE发送包含CBR相关信息的响应消息。
需要指出的是，当所述UE位于eNB的覆盖外时，如果所述UE具备PC5接收能力，则所述UE可通过PC5接收其他UE发送的CBR相关信息，可选地，所述UE向其他UE发送CBR请求消息，其他UE在PC5返回CBR相关信息；如果所述UE不具备PC5接收能力，则采用预配置的CBR或预配置的无线资源参数，为了保证UE能够发送V2X业务，上述预配置的无线资源参数一般较为保守，如较低的发射功率，较低的MCS，较小的数据块等。
步骤905：UE根据CBR相关信息发送V2X业务数据。
所述UE获取CBR相关信息：如果是CBR值，则查找对照表得到无线资源参数，并按照所述无线资源参数发送V2X业务数据；如果是全部无线资源参数，则可以直接按照所述无线资源参数发送V2X业务数据，如果是部分无线资源参数，则基于该部分无线资源参数查找对照表获取全部无线资源参数，再按照所述全部无线资源参数发送V2X业务数据；如果是索引值，则UE可以先根据所述索引值查找对应的无线资源参数，再按照所述无线资源参数发送V2X业务数据。
本申请中的上述方法可以应用于车联网V2X业务，可穿戴(Wearables)业务、MTC、公共安全(PS，Public Safety)通信、IOT、用户设备到网络 中继(UE-to-Network relay)等。
