具体实施方式
下面结合附图对本申请的具体实施方式进行说明。
发明人在发明过程中注意到：
车辆主动安全的车联网系统对通信时延有较高的要求，因此一般都采用短距离通信的自组织网络技术。目前在车联网领域，根据无线资源使用的形式，主要有两类自组织网络技术，一种是基于IEEE 802.11p的DSRC(Dedicated Short Range Communications，专用短程通信技术)技术，这是异步通信的自组织网络；另一种是以MS-Aloha(Mobile Slotted Aloha，移动分段式Aloha)为代表的同步通信自组织网络。
在蜂窝移动通信系统中，采取的是网络集中控制的方式，终端设备发送和接收数据都在网络的控制下，由系统网络分配无线资源，并且通过网络传递数据。为满足特定的通信需求，3GPP组织也已经开展了终端间直通服务的讨论和研究。在3GPP中，将基于LTE(Long Term Evolution，长期演进)的终端间直通通信方式称为D2D(Device-to-Device，设备到设备)技术，成立了关于D2D的研究小组。
蜂窝网络参与的D2D通信要实现终端之间在蜂窝网络参与下通过建立一条直连的空口链路进行通信。蜂窝网络参与的D2D通信与传统的蜂窝网络相比可以提高网络容量，增强网络覆盖，并具有高效的位置感知能力。而蜂窝网络参与的D2D通信与传统的D2D通信相比则具有更高的安全性和更好的QoS(Quality of Service，服务质量)保障。对于运营商而言，可以降低每比特成本以减少投入，并且可以提供更多的新业务。
但是，该方案中，基站覆盖内的边缘节点，发送资源由基站集中调度，而基站覆盖外节点发送资源由分布式处理的资源分配机制决定，其不足在于：目前没有资源协调机制，由于资源调度分配资源控制实体不同，而且拓扑快速变化，可能不满足空间复用的条件，发生资源碰撞。具体以下面的现有技术采用的方案进行说明。
现有技术方案1：设置脱网定时器标记时隙为脱网节点占用
当基站判定某节点可能脱网时，将该节点当前使用的时隙标记为脱网时隙，对于本小区内的节点的时隙资源在协调时，需要考虑到脱网时隙的影响(对于小区内与脱网区域有交互的范围内的节点不能使用该时隙资源)，同时开启脱网判定定时器，在脱网判定定时器超时之前，如果又收到了节点的信息(TA(Tracking Area，跟踪区)、位置上报以及信道测量量等)，则将脱网判定定时器取消，将该时隙的脱网时隙属性去掉。反之，则可以确定节点已经脱网。对于确定脱网的节点，对该时隙开启脱网时隙定时器，在脱网时隙定时器未超时的时候，对于本小区内的节点的时隙资源在协调时，需要考虑到脱网时隙的影响。当脱网时隙定时器超时之后，该时隙的脱网属性取消。
需要补充说明的是，基站可以通过如下方式检测到节点离开本小区：
1)通过D2N(Device-to-Node，设备到节点)链路信道测量量；
2)通过TA；
3)通过位置上报。
节点连续一段时间没有收到上报量时，认为节点存在离开本小区的可能。同时再结合节点上报的具体的位置信息和移动轨迹，判定节点是否存在脱网的可能。
通过以上方案，基站可以尽可能避免在为本小区节点分配时隙资源时，与从本小区移动脱网的节点的时隙发生碰撞。对于可能存在的与其他脱网节点的碰撞，采用碰撞检测的方法：当在网节点根据底层测量量(SINR(Signal to Interference plus Noise Ratio，信号与干扰和噪声比)以及接收总功率)，检测到强干扰之后，上报给基站，基站根据节点上报的强干扰指示，上报节点的位置信息以及节点的时隙占用信息，判定某一个节点与非本小区节点发生时隙碰撞的时候，基站给该节点发送特殊的碰撞指示以及节点用于可选时隙上报的资源，碰撞节点放弃使用该时隙资源，且通过自身的底层测量(SINR和接收总功率)， 给出一些可选空闲时隙的建议，上报给基站供基站来选择，基站结合此信息，并结合在网内其他节点的时隙占用情况，为节点确定最终的时隙。
脱网节点的时隙检测：脱网节点需要在FI(Format Identifier，格式标识符)中包含在网节点，只解调一跳邻节点，以特殊的STI(Statistics Time Interval，统计时间间隔)来表示，以通过脱网节点之间的协作交互尽可能避免脱网节点与在网节点发生资源碰撞。
对于由脱网状态刚接入网络的节点：基站分配资源的情况下，节点需要在接入过程中将自己当前占用的时隙需要上报给基站，由基站来确定该节点是继续使用该时隙资源还是变更新的时隙资源。
对于刚从在网状态转化到脱网状态的节点：如果没有自身检测到碰撞，继续使用现有时隙资源。
该方案通过设置脱网定时器，标记某时隙为脱网节点占用，不能再被集中调度使用。脱网场景的判断依靠D2N测量、TA以及位置上报。
其不足在于：原有方案脱网判断不准确，脱网定时器时长设置复杂，即使脱网定时器超时也不能说明脱网时隙是否满足空间复用条件；脱网时隙没有按照实际情况是否能进行空间复用来判断，会导致资源利用率低。
现有技术方案2：设置协作资源池
基站周围存在无网络覆盖区域，需要提前做一部分规划：脱网节点和基站是可以使用全部时隙资源的，但是需要各自将其中的一部分资源标记为特殊资源，构成特殊资源池，当满足一定条件时，需要各自都使用特殊资源池中的时隙资源。具体来说：
1)对于脱网节点而言，特殊资源池也叫做脱网协作资源池。当脱网节点通过监听检测比如前导码检测，判定周围存在在网节点时，就自发调整时隙资源，以确定使用的时隙资源为脱网协作资源池中的资源。当脱网节点没有检测到在网节点时，可以任意使用时隙资源。对于脱网协作资源池的配置，节点可以在处于无网络覆盖区域相邻的网络覆盖区域内时，从网络中获取到。
2)对于基站为在网节点分配资源而言，特殊资源池也叫做在网协作资源池。基站规划特殊的区域，并为处于特殊区域(边缘区域)内的节点分配时隙资源用于脱网节点检测上报。当有处于特殊区域(边缘区域)内的网节点通过监听检测比如前导码检测，判定周围存在脱网节点时，上报给基站，触发基站在为特殊区域(边缘区域)内的节点划分资源的时候，只能考虑分配在网协作资源池中的资源。当基站持续一段时间都接收不到此类信息时，认为不存在脱网节点。此时，基站分配资源的时候，只需要避免自己小区内节点时隙占用不发生碰撞以及协调好与别的小区之间的时隙占用即可，不需要考虑与脱网节点的 协作
同时，需要说明的是：
在网协作资源池与脱网协作资源池是预先静态配置好的，且这些资源池只是限于边缘节点使用。对于脱网节点，只有自身检测到在网节点之后，才算边缘节点；对于在网节点，基站主要依据的是地理位置。
脱网节点与在网节点之间的信息接收处理：
1)接收：在网节点采用频分方案，脱网节点占用整个频带资源，频分个数是预先配置好的，对于脱网节点，一旦根据前导码等确定存在脱网节点的时候，接收的时候可以采用多次盲接收方法，先子频段(半频段)接收然后再全频段接收。对于在网节点，同理。
2)解码：脱网节点发送FI在网节点不发送FI时，两者的消息格式是不同的，在帧格式头增加一个比特指示，用于区分是否存在FI，便于解码处理。
3)接收后处理：脱网节点发送FI在网节点不发送FI时，脱网节点可以在FI中表征在网节点，也可以再FI中不表征在网节点。对于前一种，只需要表征正确解码的一跳在网节点，对于在网节点，采用特殊的STI来表征，包括一跳占用以及二跳占用。
由于采用不同的资源池，脱网节点与边缘区域的在网节点不会发生时隙碰撞，同时，由于区域的划分，脱网节点也不会与可能存在时隙复用的非边缘区域在网节点发生时隙碰撞。
通过这两种方式，可以有效避免在网内的节点与脱网的节点发生碰撞；
对于刚从脱网状态接入网络的节点：基站分配资源的情况下，节点需要在接入过程中将自己当前占用的时隙需要上报给基站，由基站来确定该节点是继续使用该时隙资源还是变更新的时隙资源。如果根据节点检测，确定周围存在脱网节点时，为其分配在网协作资源池中的资源。如果确定周围不存在脱网节点，则只需要考虑该新节点是否会对现网用户造成干扰。
对于刚从在网状态转化到脱网状态的节点：立即放弃以前的资源，在脱网协作资源池中重新选择时隙资源。只有当节点时隙失败重新选择时隙时，如果根据前导码检测周围不存在脱网节点，可以在全部的资源池中选择时隙资源。
该方案通过在脱网节点和基站覆盖内节点预先静态设置正交特殊资源池，避免时隙碰撞；
其不足在于：静态配置边缘区域所用的特殊资源池，资源配置不灵活；从在网转为脱网，必须重新选择时隙，不满足业务连续性的设计原则。
基于此，本申请提出了一种基于网络的资源协调方案，通过网络覆盖边缘节点发送资 源协调消息，来使得覆盖边缘与覆盖外节点资源协调，保证了节点在网络覆盖边缘移动过程中资源的连续性，减少了资源碰撞，提高了系统资源的利用率。下面进行说明。
在说明过程中，将分别从节点与基站侧的实施进行说明，但这并不意味着二者必须配合实施，实际上，当节点与基站分开实施时，其也各自解决节点侧、基站侧的问题，只是二者结合使用时，会获得更好的技术效果。
图1为基站侧的资源信息发送方法实施流程示意图，如图所示，可以包括：
步骤101、确定第二类节点使用的资源以及第一类节点使用的资源，第一类节点是位于基站信号覆盖范围内的节点，第二类节点是位于基站信号覆盖范围外的节点；
步骤102、确定接收资源协调消息的第一类节点；
步骤103、向确定的第一类节点发送资源协调消息，并指示该第一类节点广播资源协调消息的内容，资源协调消息中携带有第一类节点与第二类节点的资源信息。
实施中，确定第二类节点使用的资源可以是根据干扰信息确定的。
具体实施中，所述干扰信息可以是第一类节点上报的干扰信息。
图2为节点侧的资源信息广播方法实施流程示意图，如图所示，可以包括：
步骤201、接收基站发送的资源协调消息，并且基站指示广播该资源协调消息的内容，所述资源协调消息中携带有第一类节点与第二类节点的资源信息，其中，第一类节点是位于基站信号覆盖范围内的节点，第二类节点是位于基站信号覆盖范围外的节点。
步骤202、广播所述资源协调消息的内容。
下面先对实施申请方案的位于基站覆盖“边缘”的第一类节点进行说明。
对于用以解决避免资源碰撞的资源占用信息而言，在基站覆盖范围内，对于需要获知节点资源占用信息的第一类节点，若其位于覆盖范围“内圈”，由于受到覆盖范围外的第二类节点的干扰较小，其不需获知第二类节点的资源使用情况，而第一类节点的资源使用情况均可由基站进行协调，因此，覆盖范围“内圈”实际上可以不需要资源占用信息，需要获知资源占用信息的是位于覆盖范围“边缘”的第一类节点。
对于需要获知节点资源占用信息的基站覆盖外的第二类节点，由于其获知的方式是通过第一类节点的广播来获知的，而第一类节点的广播范围小于基站覆盖范围，因此，实际上其能获知的也是位于覆盖范围“边缘”的第一类节点广播的资源使用信息，
综上，实施中，可以根据干扰范围以及广播范围来确定“边缘”的范围，也即根据二者选择位于覆盖范围“边缘”的第一类节点来实施上述方案。
由于节点与基站传输信息是通过无线传输的，因此，从理论上说，与界定“边缘”有关的干扰以及广播范围是无限的，只是信号的强弱，但是在实施中，是可以给出最适于根 据干扰以及广播来界定的本申请中的“边缘”的，具体实施中，可以是：
对于干扰的范围，可以分为强干扰范围以及较强干扰范围，强干扰是指由于干扰过强以至于不能解码任何发送信号；较强干扰是指虽然干扰较强，但至少能成功解码其中一个发送信号。
对于广播的范围可以是指D2D的通信范围。
下面还将会在具体实例中对其进行说明。
通过图1、2的方案，可以通过基站配置覆盖内边缘节点发送资源集中调度信息，使得覆盖外节点能获取覆盖内边缘节点的资源占用情况，避免资源碰撞。下面结合基站侧与节点侧的实施来进行说明，说明中，为便于理解采用了“边缘”这一用语，而该用语参见上述解释。
方案中主要包括：
1)基站覆盖边缘节点判断处于基站覆盖边缘，周围有覆盖外节点，覆盖边缘节点上报基站请求配置资源协调消息；
2)基站根据网络覆盖边缘节点上报的请求以及网络覆盖内节点上报的干扰信息，组织发送集中调度资源协调消息；
3)基站覆盖边缘节点组织发送集中调度的资源协调消息；
4)基站覆盖外节点收到资源协调消息后，分析资源可能碰撞情况，对可能发生碰撞的资源进行调整。
具体实施中，覆盖边缘的第一类节点可以是接收到的D2D SS不同的节点，也即，判断节点处于基站覆盖边缘，周围有覆盖外节点可以如下：
考虑eNB覆盖内UE作为参考同步源的优先级高于覆盖外UE，且通过D2D同步序列，即D2D SS(D2D Synchronization Sequence，D2D同步序列)序列可以区分是来自eNB的同步还是来自UE的同步。则基站覆盖边缘节点、周围有覆盖外节点的确定方式为：
当节点处于基站覆盖内，当节点测量的D2N链路RSRP(Reference Signal Received Power，参考信号接收功率)低于门限值，需要发送D2D SS；
同时节点接收到覆盖外节点发来的D2D SS，由于eNB覆盖内和覆盖外D2D SS序列不同，可以确认该节点处于基站覆盖边缘，周围有覆盖外节点。
实施中，可以向基站发送获取资源协调消息的请求。
进一步的，可以在确定接收到的D2D SS不同时，向基站发送获取资源协调消息的请求。
具体实施中，当节点第一次满足处于基站覆盖边缘，周围有覆盖外节点的条件，立即 上报基站请求发送消息，消息中还可以包括以下内容：
节点ID(Indentity，标识)；
节点位置信息：经度、纬度、车道；
节点行驶信息：速度、行驶方向、加减速。
实施中，基站根据网络覆盖边缘节点上报的请求以及网络覆盖内节点上报的干扰信息，组织发送集中调度资源协调消息。
网络覆盖内节点干扰上报可能有以下情况：
1)强干扰上报：接收节点由于干扰过强，无法解码任何接收到的发送信号；
覆盖内节点检测到强干扰上报基站；
基站根据强干扰的时隙资源，查找集中调度的节点信息；
如果找到资源碰撞节点在基站覆盖内，对基站覆盖内节点进行资源重分配，也即，实施中，在向该第一类节点发送资源协调消息前，还可以进一步包括：根据上报的干扰信息调整相关的第一类节点使用的资源；相应的，向该第一类节点发送资源协调消息时，所述资源协调消息中携带的第一类节点的资源信息是调整后的第一类节点使用的资源信息；
如果找不到资源碰撞的任何节点信息，说明资源碰撞节点在网络覆盖外。
2)较强干扰上报：接收节点虽然干扰较强，但能成功解码其中一个接收到的发送信号；
覆盖内节点检测到较强干扰上报基站；
基站根据较强干扰的时隙资源，查找集中调度的节点；
如果找到资源碰撞节点在基站覆盖内，如果判断发生资源碰撞，对基站覆盖内节点进行资源重分配；如果判断不发生资源碰撞，不进行后续处理；
如果找不到资源碰撞的任何节点信息，说明资源碰撞节点在网络覆盖外，为了保证覆盖外接收可靠性，后续通过覆盖边缘节点广播资源碰撞信息。
当基站收到节点上报的消息，可能包括2类消息：
1)基站覆盖边缘节点上报的资源协调请求消息；
2)基站覆盖内节点上报的强干扰信息、较强干扰信息；
则，在确定能够根据上报的干扰信息确定第二类节点使用的资源的第一类节点，并根据该第一类节点确定接收资源协调消息的第一类节点时，以该节点是车为例，基站可以根据该车(第一类节点)所处位置，以及行驶信息，选择发送的节点，包括以下方式：
1)只选择一个上报资源协调请求消息的边缘UE，如选择最远离基站的覆盖边缘节点；
2)根据基站的资源情况，选择部分或者全部上报资源协调请求消息的边缘UE。
实施中，在确定接收资源协调消息的第一类节点时，容易知道，发送资源协调消息的目的在于使得覆盖内以及覆盖外的各节点避免资源碰撞，而避免资源碰撞的目的在于能够传输信息，那么，仅需要确定需要进行信息的收发的节点，以及需要避免资源碰撞的节点，结合各节点的物理位置、运动状态等信息，即可确定出接收资源协调消息的第一类节点。当然，实践中也可以根据需要、或其他目的来设定各种确定接收资源协调消息的节点的规则。
实施中，对于多个UE发送资源协调请求消息的情况，发送方式可以为发送内容相同的多个节点同时同步的广播发送，也可以是不考虑消息内容，给多个UE分别分配发送资源，分别发送资源协调请求消息。
实施中，资源协调消息中携带有第一类节点与第二类节点的资源信息，具体的，对于上述选择的发送节点，基站发送给上报节点的辅助组织资源协调节点信息，可以包括2类信息：
1)基站覆盖内节点资源占用信息：
基站将边缘节点到基站间空间复用距离内的已集中调度分配的节点信息，包括以下内容：
基站覆盖内节点ID；
基站覆盖内节点资源占用信息。
2)基站覆盖外节点资源碰撞信息：
基站将基站覆盖的边缘节点判断出的基站覆盖外节点的资源碰撞信息进行组织，包括以下内容：
基站覆盖外节点资源占用信息。
实施中，向该第一类节点发送资源协调消息，并指示该第一类节点广播资源协调消息的内容，具体的，基站组织覆盖边缘节点发送集中调度资源协调消息，基站覆盖边缘节点收到基站发送的资源协调消息，以广播方式组织发送集中调度资源协调消息；
实施中，基站覆盖外节点收到资源协调消息，可以对可能发生碰撞的资源进行调整；具体的，基站覆盖外节点收到资源协调消息后，作为分布式资源碰撞判断的输入，分析资源可能碰撞情况，对可能发生碰撞的资源进行调整。
下面以实例进行说明。
需要说明的是，实施例中的节点是以车为例的，在描述时，分别有：向基站发送获取资源协调消息请求的节点，如车A，其接收到的D2D SS不同；向基站上报干扰信息的节点，如车D。虽然，例中被基站确定接收资源协调消息的节点多是这两类节点，但是，基 站确定接收资源协调消息的节点，或者接收到基站发送的资源协调消息的节点并不必然是这两类节点，它们仅用以示例，事实上，被基站确定接收资源协调消息的节点如前所述，可以根据需要确定。
实施例1：无资源碰撞下的资源协调
图3为无资源碰撞下覆盖内与覆盖外节点示意图，如图所示，车A处于基站覆盖内的边缘区域，车B处于基站覆盖外。
对车而言有2种可能情况：
情况1、车A持续发送D2D SS，没有收到覆盖外节点发来的同步信号，不需要发送资源协调消息；
情况2、车A能接收到覆盖外的车B发来的D2D SS，需要发送资源协调消息；
对于需要进行资源协调的情况2的按如下方式实施：
步骤一：
车A能接收到覆盖外的车B发来的D2D SS，由于eNB覆盖内和覆盖外D2D SS序列不同，车A确认车A处于基站覆盖边缘，周围有覆盖外节点车B，需要发送资源协调消息；
具体的，当车A第一次满足处于基站覆盖边缘，周围有覆盖外节点(车B)的条件，立即上报基站请求消息，消息中可以包括以下内容：
车A节点ID；
车A的节点位置信息：经度、纬度、车道；
车A的节点行驶信息：速度、行驶方向、加减速。
步骤二：
当基站收到车A上报的资源协调请求消息后，查看当前没有干扰信息上报，根据车A所处位置，以及行驶信息，选择进行资源协调的节点为车A。
组织发送集中调度分配的资源信息，由于无干扰信息，仅包括资源占用信息，基站将边缘节点到基站间空间复用距离内的已集中调度分配的节点信息，组织为资源协调消息，发送给上报节点：
基站覆盖内节点ID；
基站覆盖内节点资源占用信息。
步骤三：
基站覆盖边缘节点车A收到基站发送的资源协调消息，以广播方式组织发送集中调度资源协调消息。
步骤四：
基站覆盖外节点车B收到资源协调消息后，作为分布式资源碰撞判断的输入，分析资源可能碰撞情况，对可能发生碰撞的资源进行调整。
实施例2：有强干扰信息需要资源协调
图4为有强干扰上报的覆盖内与覆盖外节点示意图，如图所示，车A、D处于基站覆盖内边缘区域，车C处于基站覆盖内，车B处于覆盖外。其中车B和车C占用相同的时频资源进行发送，车D检测到车B和车C的发送资源碰撞。则可按如下方式实施：
步骤一：
由于车A处于基站覆盖内的边缘区域，需要持续发送D2D SS。当车A接收到覆盖外的车B发来的D2D SS，由于eNB覆盖内和覆盖外D2D SS序列不同，车A确认车A处于基站覆盖边缘，周围有覆盖外节点车B。
具体的，当车A第一次满足处于基站覆盖边缘，周围有覆盖外节点(车B)的条件，立即上报基站请求消息，消息中可以包括以下内容：
车A节点ID；
车A的节点位置信息：经度、纬度、车道；
车A的节点行驶信息：速度、行驶方向、加减速；
步骤二：
覆盖边缘节点车D检测到强干扰，之后将强干扰指示上报基站。
基站根据强干扰的时频资源，查找集中调度分配的节点信息，找到资源碰撞节点在基站覆盖内为车C，于是基站对车C进行资源重分配；同时基站未找到与车C发生资源碰撞的其它节点信息，说明资源碰撞的另一个节点在网络覆盖外。之后基站配置该上报节点车D对资源碰撞情况进行广播；
基站收到车A上报的资源协调请求消息，又收到基站覆盖边缘节点车D上报的强干扰指示，根据车A和车D所处位置，以及行驶信息，基站可以有以下方式选择需要发送资源协调消息的节点：
1、判断目前车D比车A更靠近基站覆盖边缘，选择车D为当前边缘区域节点。
2、目前基站的时频资源支持车A和车D都发送资源协调消息，选择车A和车D都发送。
基站组织发送集中调度分配的资源信息给需要发送的车辆节点，包括资源占用信息和强干扰信息，基站将边缘节点到基站间空间复用距离内的已集中调度分配的节点信息，组织为资源协调消息，可以包括2类信息：
1、基站覆盖内节点资源占用信息：
基站将需要发送的车辆节点到基站间空间复用距离内的已集中调度分配的节点信息，可以包括以下内容：
基站覆盖内节点ID：包含车辆ID，通过车辆查找空间复用距离内基站已集中调度节点；
基站覆盖内节点资源占用信息：上述节点的资源占用信息。
2、基站覆盖外节点资源碰撞信息：
基站将基站覆盖的边缘节点判断出的基站覆盖外节点的资源碰撞信息进行组织，包括以下内容：
基站覆盖外节点资源占用信息：因为无法知道覆盖外节点ID，可以只填入发生资源碰撞的资源信息。
步骤三：
基站覆盖边缘节点收到基站发送的资源协调消息，以广播方式发送集中调度资源协调消息。
步骤四：
基站覆盖外节点车B收到资源协调消息后，作为分布式资源碰撞判断的输入，分析资源可能碰撞情况，对可能发生碰撞的资源进行调整。
实施例3：有强干扰和较强干扰信息需要资源协调
图5为没有资源碰撞的覆盖内与覆盖外节点示意图，如图所示，车A、车D、车C处于基站覆盖内边缘区域，车E处于基站覆盖内，车B、车F处于覆盖外。其中车B和车C占用相同的时频资源进行发送，车D检测到车B和车C的发送资源碰撞。其中车B和车C占用相同的时频资源进行发送，车D检测到车B和车C的发送资源碰撞。则可按如下方式实施：
步骤一：
车A处于基站覆盖内，持续发送D2D SS，当车A接收到覆盖外的车B发来的D2D SS，由于eNB覆盖内和覆盖外D2D SS序列不同，车A确认车A处于基站覆盖边缘，周围有覆盖外节点车B。
当车A第一次满足处于基站覆盖边缘，周围有覆盖外节点(车B)的条件，立即上报基站请求消息，消息中可以包括以下内容：
车A节点ID；
车A的节点位置信息：经度、纬度、车道；
车A的节点行驶信息：速度、行驶方向、加减速；
步骤二：
覆盖边缘节点车D检测到强干扰，之后将强干扰指示上报基站。
基站根据强干扰的时频资源，查找集中调度分配的节点信息，找到资源碰撞节点在基站覆盖内为车C，于是基站对车C进行资源重分配；同时基站未找到与车C发生资源碰撞的其它节点信息，说明资源碰撞的另一个节点在网络覆盖外。之后基站配置该上报节点车D对资源碰撞情况进行广播。
覆盖边缘节点车C检测到较强干扰，将较强干扰指示上报基站，其中较强干扰指示包括车C解码成功的车F节点ID，以及发生资源碰撞的资源信息。基站根据较强干扰的时隙资源，查找集中调度的节点信息，找到资源碰撞节点在基站覆盖内为车E，基站对车E进行资源重分配。如果车C解码成功的是车E，较强干扰指示上报车E的节点ID，以及发生资源碰撞的资源信息。基站根据较强干扰的时隙资源，查找集中调度的节点信息，未找到与车E发生资源碰撞的其它节点信息，说明资源碰撞节点在网络覆盖外，为了保证覆盖外接收可靠性，需要通过覆盖边缘节点广播资源碰撞信息。
基站收到车A上报的资源协调请求消息，又收到基站覆盖边缘节点车D上报的强干扰指示，以及收到基站覆盖边缘节点车C上报的较强干扰信息。根据车A、车D和车C所处位置，以及行驶信息，基站可以有以下方式选择需要发送资源协调消息的节点：
1、判断目前车D比车A和车C更靠近基站覆盖边缘，只选择车D为当前边缘区域节点。
2、判断目前基站的时频资源仅支持车A和车D都发送资源协调消息，选择车A和车D都发送；
3、判断目前基站的时频资源支持所有车都发送资源协调消息，选择车A、车C和车D都发送。
基站组织发送集中调度分配的资源信息给需要发送的节点，包括资源占用信息和强干扰信息。基站也跟进消息内容情况，配置发送资源，如果消息内容相同，可以配置多个发送节点同时同步发送，如果消息内容不同，分别配置发送节点的发送资源。基站将边缘节点到基站间空间复用距离内的已集中调度分配的节点信息，组织为资源协调消息，可以包括2类信息：
