具体实施方式
下文中将参考附图并结合实施例来详细说明本公开。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组合。
需要说明的是，本公开的说明书和权利要求书及上述附图中的术语“第一”、“第二”等是用于区别类似的对象，而不必用于描述特定的顺序或先后次序。
车联网V2X：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、车与人V2P、车与路(基础设施)V2I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。图1是本公开相关技术中车联网的示意图。
近年来随着新的移动通信技术的发展，国际上出现了使用LTE技术来解决基于车联网通信应用的研究。
路边通信单元RSU(Road Side Unit)可以接收车辆请求,保证车辆接入Internet，有网关的功能；此外,它也拥有数据运算、存储、转发的功能。
相关技术中有两种车联网实现技术：专用短距离通信(DSRC,Dedicated Short Range Communication)和LTE，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技术刚开始讨论，还没有标准。
相关技术中3GPP正在讨论的LTE V2X技术包括：RSU可通过静止的UE或eNB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的空中接口，Uu接口是指UE到eNB的空中接口。通过PC5口发送V2X业务的系统架构如图2所示，图2是本公开相关技术中通过PC5口发送V2X业务的系统架构图。
在3GPP正在研究的LTE V2X课题中，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P(Pedestrian，行人)一般不具备PC5接收的能力，即无法采用感知选择资源。
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传输参数，为此，3GPP中采用CBR(Channel Busy Ratio，信道忙率)衡量信道的拥塞程度，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S-RSSI(Sidelink-Received Signal Strength Indication，边路-接收信号强度指示)标识，门限值为事先确定，UE根据网络侧的测量配置测量计算CBR；针对某个给定的CBR，网络侧基于每个V2X优先级(采用PPPP-ProSe(Proximity based Services，基于临近区域的业务)Per-Packet Priority，Prose分组优先级)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根据CBR选择对应的无线资源参数。
为了便于描述，本文中V-UE是指Vehicle-UE，P-UE是指Pedestrian-UE。

实施例3
针对相关技术，申请人发现存在以下问题：两种资源配置方式的资源池相互独立，不同配置方式的负载水平一般不同，可能造成不同模式资源池的利用率差别，如某个模式的资源池利用不足，而另外模式的资源池拥塞；针对该场景，需要解决不同模式资源池如何配置的问题。
在共享资源池中设置mode3专用资源；如果mode3专用资源池发生拥塞，则基站从共享资源池中mode4资源中选择mode3所需PC5资源，并通过广播信令通知UE；如果共享资源池中mode4资源发生拥塞，则mode4UE向基站发送拥塞指示信息，基站根据指示信息选择部分mode3专用资源用于mode4UE资源选择并通过广播信令通知。

所述共享资源池是指：mode3和mode4共享的资源池，其中包括mode3的专用资源。图7是本公开实施例中共享资源池的示意图，其中mode3专用资源正常情况下只用于mode3传输，共享资源池中除mode3专用资源之外的资源用于mode4传输；如果mode3专用资源发生拥塞，则基站可调用mode4的部分资源用于mode3传输，并发送广通信令通知；如果mode4资源发生拥塞，则检测到拥塞的UE上报基站，基站可配置部分mode3专用资源用于mode4传输，并发送广播信令通知。
如无特殊说明，在共享资源池中除mode3专用资源之外的资源在本文中称为mode4资源。
所述共享资源池包括：时域和频域资源信息。其中时域资源以子帧为单位，频域资源以资源块(RB，Resource Block)或子信道(sub channel)为单位，子信道为连续的多个RB。所述共享资源池可用于PSCCH(Physical Sidelink Control Channel，物理边路控制信道)和/或PSSCH(Physical Sidelink Shared Channel，物理边路共享信道)。
所述eNB通过系统消息SIB或专用RRC(Radio Resource Control，无线资源控制)信令指示PC5的共享资源池配置参数。
PC5通信包括同频或异频，同频是指：Uu和PC5通信共享频率，异频是指：PC5通 信采用专用频率，如5.9GHz V2X频率。
所述PC5是指UE之间的接口，也可以采用其他名称表示(如sidelink)。PC5接口可采用授权频谱的Prose技术，无线局域网WLAN/WiFi(如802.11系列)，蓝牙Bluetooth，或红外等无线传输技术。
实现步骤：图8是本公开实施例的流程示意，包括：
步骤1：基站配置共享资源池。
所述配置包括以下内容：共享资源池，mode3专用资源，UE测量配置，UE上报配置；其中：mode3专用资源为共享资源池中的一部分资源，正常情况下只用于mode3传输，除非发生资源拥塞或过载，则基站可根据拥塞程度调整mode3专用资源的大小，在共享资源池中除mode3专用资源之外的资源在本文中称为mode4资源；UE测量配置是指用于UE测量共享资源池拥塞程度的配置参数，如CBR配置；UE上报配置是指：需要上报的UE，用于触发UE上报的门限值或上报周期；
所述配置通过系统广播消息发送，所述系统广播信息包括现有Prose系统消息或新增的V2X专用系统消息；
步骤2：判断共享资源池是否发生拥塞？如果是，转向步骤3，否则转向步骤4。
所述判断由采用共享资源的UE根据测量结果确定，如所述UE测量的CBR超过预先规定的门限，则UE确定发生拥塞，所述UE向基站上报拥塞指示信息，所述拥塞包括mode3和/或mode4拥塞。其中mode3资源拥塞由采用mode3资源的UE测量和确定，mode4资源拥塞由采用mode4资源的UE测量和确定。所述上报信息采用RRC信令承载。
步骤3：基站重新配置共享资源池。
所述基站收到拥塞指示信息，则根据拥塞程度重新配置共享资源池：如果mode3资源拥塞而mode4不拥塞，则基站在mode4资源中选择用于mode3的资源，并发送广播信令通知使用共享资源池的UE，则采用mode4资源的UE在上述mode3资源之外感知并选择、预约所需的PC5资源；如果mode4资源拥塞而mode3不拥塞，则基站在mode3资源中选择部分资源用于mode4传输，并发送广播信令通知使用共享资源池的UE，则采用mode4资源的UE在上述mode3资源之内(基站指示的部分资源)感知并选择、预约所需的PC5资源；如果mode3和mode4资源都拥塞，则基站可扩大共享资源池，并在新的共享资源池中划分mode3专用资源，即同时增加mode3和mode4资源的大小，基站发送广播信令通知使用共享资源池的UE，增加的资源池大小由基站根据拥塞程度和可用PC5资源确定。
步骤4：UE根据共享资源池配置进行V2X信息收发。
共享资源池没有发生拥塞，则所述UE根据共享资源池的配置进行V2X信息收发：即采用mode3的UE根据基站指示在mode3专用资源中收发V2X信息，采用mode4的UE在mode4资源中自主选择资源收发V2X信息。
本公开的方法可以应用于车联网V2X业务，可穿戴(Wearables)业务，机器类型通 信MTC(Machine Type Communication)，公共安全(PS，Public Safety)通信，物联网IOT(Internet Of Thing),UE-to-Network relay等。

图14为本实施方式六提供的共享资源池的示意图一，图中共享资源池1,2为mode3和mode4共用资源，即mode3和mode4UE都可以使用其中的资源，mode4为自主选择资源，mode3为基站调度资源，由于mode4UE不知道基站的调度信息，基站也不知道mode4选择资源的信息，则可能发生资源冲突。为了减少冲突并保证mode3传输的可靠性，需要mode3UE对共享资源池进行感知、测量，并将感知测量结果上报基站，优选的，如果结果表明共享资源池拥塞程度高，则基站可优先选择mode3资源进行调度，如果拥塞程度低，则基站可从共享资源池选择调度mode3传输所需资源；如果基站调度共享资源池的资源用于mode3，则发送广播信息通知，同时采用mode3传输的UE在相应边路控制信息(SCI，Sidelink Control Information)中指示mode3预约资源信息，采用mode4的UE根据广播信息或感知的SCI信息确定mode3资源，然后自主选择共享资源池中的其他资源。
所述共享资源池可完全共享，即mode3和mode4共享所有的PC5资源，图15为本实施方式六提供的共享资源池的示意图二。
实施方式七系统结构实施方式
