Description

一种资源分区聚合方法和装置
本申请要求于2016年9月14日提交中国专利局，申请号为201610824371.0、发明名称为“一种资源分区聚合方法和装置”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
本发明涉及电子技术领域，尤其涉及一种资源分区聚合方法和装置。
背景技术
Zone资源分区是3GPP（3rd Generation Partnership Project，第三代合作伙伴计划）在D2D（(Device-to-Device，设备对设备）基础上针对V2X（Vehicle to X，车载终端到其他终端）提出的概念，将交通空间以地理zone的方式进行划分，VUE（Vehicle User Equipment，车载用户设备）通过模操作确定VUE 所在的zone，并获知使用哪一个资源池。
在现有技术方案中，如图1所示，图1现有技术方案提供的一种信号单元cell中资源分区的结构示意图。将zone以网格的形式进行划分，zone的大小由eNB定义，参考点（0，0）固定，一个cell中的zone通过zone index区域索引进行标记，如：
Figure WO40427-appb-I000001
，一个资源池或多个资源池对应一个zone index。在VUE端，可以预先配置一个哈希函数，将GPS（Global Positioning System，全球定位系统）定位获取到的地理位置(x，y)转化为zone index，哈希函数如下：
Figure WO40427-appb-I000002

Figure WO40427-appb-I000003
，其中，
Figure WO40427-appb-I000004
是参考点，(L，W)是zone的大小，
Figure WO40427-appb-I000005
是一个cell中zone index的最大值。但是，由于cell中的一个zone使用一个资源池，导致车流量较大的zone资源紧张而车流量较小的zone资源浪费，资源池分配与资源池需求达不到充分利用，资源利用率低。

具体实施方式
下面将结合本发明实施例中的附图，对本发明实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例是本发明一部分实施例，而不是全部的实施例。基于本发明中的实施例，本领域普通技术人员在没有作出创造性劳动前提下所获得的所有其他实施例，都属于本发明保护的范围。
请参考图2，图2是本发明第一实施例提出的一种资源分区聚合方法的流程示意图。本发明实施例的执行主体可以为基站，如图所示，本发明实施例中的方法包括：
S201，获取第一信号单元中每个资源分区的资源利用率。
S202，判断所述第一信号单元中是否存在相邻的至少两个资源分区中每个资源分区的资源利用率小于第一预设阈值。
具体实现中，若所述第一信号单元中不存在相邻的至少两个资源分区中每个资源分区的资源利用率小于第一预设阈值。如图4所示，
S203，若存在，确定所述相邻的至少两个资源分区聚合后所使用的区域索引是否与邻近的第二信号单元中资源分区所使用的区域索引产生通信干扰。
S204，若不产生通信干扰，确定所述相邻的至少两个资源分区聚合后的区域分布参数。
S205，向车载终端发送携带有区域分布参数的广播消息，所述广播消息用于指示所述车载终端根据所述区域分布参数和预先获取的地理位置确定所述车载终端所在的资源分区的区域索引并使用该区域索引对应的资源池。
请继续参考图3，图3是本发明第二实施例提出的一种资源分区聚合方法的流程示意图。结合图2所示的步骤，本发明实施例的具体执行流程如下：
S301，第一基站获取第一信号单元中每个资源分区的资源利用率。
具体实现中，将第一基站覆盖的第一信号单元划分为多个资源分区，并使用不同的区域索引对多个资源分区进行标识，如图4所示，seNB（第一基站）覆盖的第一信号单元包括4×4个资源分区，资源分区分别使用（0，0）、（0，1）、……、（3，3）等区域索引进行标注，同样NeNB（第二基站）覆盖的第二信号单元也包括4×4个资源分区，资源分区分别使用（0，0）、（0，1）、……、（3，3）等区域索引进行标注，由于靠近两个信号单元之间的交界处的两个资源分区分别使用不同的区域索引，因此不会产生通信干扰。另外，由于每个资源分区中的车载终端的数量不同，因此每个资源分区的资源利用率也不相同，如果某个资源分区中的车载终端的数量的越多，则该资源分区的资源利用率越高，可以实时监控每个资源分区中信号传输数量进而获取每个资源分区的资源利用率。
S302，第一基站判断所述第一信号单元中是否存在相邻的至少两个资源分区中每个资源分区的资源利用率小于第一预设阈值。
具体实现中，如果所述第一信号单元中不存在相邻的至少两个资源分区中每个资源分区的资源利用率小于第一预设阈值，则对第一信号单元中的资源分区不需要进行聚合。
S303，若存在，则第一基站判断所述至少两个资源分区中每个资源分区是否靠近所述第一信号单元与所述第二信号单元之间的边界处。
具体实现中，如图5所示，区域索引（1，2）对应的资源分区和区域索引（2，2）对应的资源分区的资源利用率均小于第一预设阈值，则可以判断区域索引（1，2）对应的资源分区或区域索引（2，2）对应的资源分区是否靠近第一信号单元与第二信号单元之间的边界处。
以下提供了靠近所述边界处和不靠近所述边界处的两种场景，S304-S305是不靠近所述边界处时的执行流程，S306-S310是靠近所述边界处时的执行流程：
S304，若不靠近所述边界处，则第一基站确定所述相邻的至少两个资源分区聚合后的区域分布参数。
具体实现中，如图5所示，区域索引（1，2）对应的资源分区和区域索引（2，2）对应的资源分区不靠近所述边界处，因此区域索引（1，2）对应的资源分区和区域索引（2，2）对应的资源分区聚合后，与第二信号单元中的资源分区不会产生通信干扰，因此第一基站不需要与第二信号单元所属的第二基站进行交互，直接确定所述相邻的至少两个资源分区聚合后的区域分布参数。例如，将资源分区的区域索引的聚合过程定义为一个函数△，

具体实现中，如果车载终端在所述相邻的至少两个资源分区聚合后新的资源分区内，则第一基站可以向车载终端发送携带有所述相邻的至少两个资源分区聚合后的新的资源分区的区域分布参数的广播消息，如果车载终端在其他没有聚合的资源分区内，则第一基站可以向车载终端发送未聚合的资源分区的区域分布参数的广播消息，其中，区域分布参数可以包括计算区域索引所需的哈希函数以及哈希函数中的计算参数。
S306，若靠近所述边界处，则第一基站向所述第二信号单元所属的第二基站发送所述相邻的至少两个资源分区中每个资源分区的区域索引。
具体实现中，如图6所示，区域索引（1，2）对应的资源分区和区域索引（1，3）对应的资源分区需要聚合，但区域索引（1，3）对应的资源分区靠近第一资源分区和第二资源分区的边界处，由于区域索引（1，2）对应的资源分区和区域索引（1，3）对应的资源分区聚合后的新的资源分区可能与第二资源分区中靠近所述边界处的资源分区使用相同的区域索引，因此，第一基站需要与第二信号单元所属的第二基站进行交互，向第二基站发送所述相邻的至少两个资源分区中每个资源分区的区域索引。
可选的，又如图7所示，区域索引（3，2）对应的资源分区和区域索引（1，3）对应的资源分区需要聚合，但这两个资源分区分别与其他两个信号单元（第二信号单元和第三信号单元）接壤，由于区域索引（3，2）对应的资源分区和区域索引（3，3）对应的资源分区聚合后的新的资源分区可能与其他两个信号单元中靠近边界处的资源分区使用相同的区域索引，因此，第一基站需要同时与其他两个信号单元所属的基站进行交互，分别向第二基站和第三基站发送所述相邻的至少两个资源分区中每个资源分区的区域索引。
S307，第二基站确定所述第二信号单元中资源分区所使用的区域索引是否与所述相邻的至少两个资源分区中每个资源分区的区域索引相同。
具体实现中，如图6所示，由于第二信号单元中资源分区没有进行聚合，而第一信号单元中的区域索引（1，2）对应的资源分区和区域索引（1，3）对应的资源分区聚合后的新的资源分区所使用的区域索引可能为（1，2）或（1，3），与边界处的第二信号单元中区域索引（1，0）不相同，因此确定所述相邻的至少两个资源分区聚合后所使用的区域索引与所述第二信号单元中资源分区所使用的区域索引不产生通信干扰。
如图8所示，第二信号单元中靠近边界处的区域索引（1，1）对应的资源分区和区域索引（1，2）对应的资源分区进行了聚合，聚合后的新的资源分区的区域索引为（1，1），而第一信号单元中区域索引（1，2）对应的资源分区和区域索引（1，3）对应的资源分区聚合后的新的资源分区所使用的区域索引可能为（1，2）或（1，3），因此，第二信号单元中靠近所述边界处的资源分区聚合后的新的资源分区所使用的区域索引与所述相邻的至少两个资源分区中每个资源分区的区域索引不相同，因此第二基站通知第一基站所述第二信号单元中靠近所述边界处的资源分区聚合后的新的资源分区所使用的区域索引与所述相邻的至少两个资源分区中每个资源分区的区域索引不相同。
如图9所示，第二信号单元中靠近边界处的区域索引（1，1）对应的资源分区、区域索引（1，2）对应的资源分区、区域索引（1，3）对应的资源分区进行了聚合，聚合后的新的资源分区的区域索引为（1，2），而第一信号单元中的区域索引（1，2）对应的资源分区和区域索引（1，3）对应的资源分区聚合后的新的资源分区所使用的区域索引可能为（1，2）或（1，3），因此第二信号单元中靠近所述边界处的资源分区聚合后的新的资源分区所使用的区域索引（1，2）与第一信号单元中聚合后的新的资源分区所使用的区域索引（1，2）相同，如果所述相邻的至少两个资源分区聚合后的新的资源分区使用区域索引（1，2），则与所述第二信号单元中资源分区所使用的区域索引产生通信干扰，因此，第二基站需要通知第一基站所述第二信号单元中靠近所述边界处的资源分区聚合后的新的资源分区所使用的区域索引与所述相邻的至少两个资源分区中目标资源分区所使用的区域索引相同。
如图7所示，第二信号单元中靠近边界处的区域索引（3，0）对应的资源分区、区域索引（3，1）对应的资源分区、区域索引（3，2）对应的资源分区进行了聚合，聚合后的新的资源分区的区域索引为（3，2），第三信号单元中靠近边界处的（0，2）对应的资源分区、区域索引（1，2）对应的资源分区、区域索引（2，2）对应的资源分区进行了聚合，聚合后的新的资源分区的区域索引为（0，2），而第一信号单元中区域索引（3，2）对应的资源分区和区域索引（3，3）对应的资源分区聚合后的新的资源分区可能使用相同的区域索引（3，2）或（3，3），因此第二信号单元中靠近所述边界处的资源分区聚合后的新的资源分区所使用的区域索引（3，2）与第一信号单元中的聚合后的新的资源分区所使用的区域索引（3，2）相同，而第三信号单元中靠近所述边界处的资源分区聚合后的新的资源分区所使用的区域索引与所述相邻的至少两个资源分区中每个资源分区的区域索引均不相同，第二信号单元所属的第二基站需要通知第一基站所述第二信号单元中靠近所述边界处的资源分区聚合后的新的资源分区所使用的区域索引与所述相邻的至少两个资源分区中目标资源分区所使用的区域索引相同，第三信号单元所属的第三基站通知第一基站所述第二信号单元中靠近所述边界处的资源分区聚合后的新的资源分区所使用的区域索引与所述相邻的至少两个资源分区中每个资源分区的区域索引不相同。
S308，第二基站向第一基站发送聚合指示信息。
其中，所述聚合指示信息包括所述第二信号单元中靠近所述边界处的资源分区聚合后的新的资源分区所使用的区域索引与所述相邻的至少两个资源分区中目标资源分区所使用的区域索引相同，或所述聚合指示信息包括所述第二信号单元中靠近所述边界处的资源分区未进行聚合，或所述聚合指示信息包括所述第二信号单元中靠近所述边界处的资源分区聚合后的新的资源分区所使用的区域索引与所述相邻的至少两个资源分区中每个资源分区的区域索引不相同。
S309，第一基站确定所述相邻的至少两个资源分区聚合后的区域分布参数。
具体实现中，在第一基站接收到聚合指示信息之后，首先可以根据所述聚合指示信息，确定所述相邻的至少两个资源分区聚合后所使用的区域索引是否与所述第二信号单元中资源分区所使用的区域索引产生通信干扰。
进一步的，如果所述聚合指示信息包括所述第二信号单元中靠近所述边界处的资源分区聚合后的新的资源分区所使用的区域索引与所述相邻的至少两个资源分区中目标资源分区所使用的区域索引相同，去除所述相邻的至少两个资源分区中所述目标资源分区所使用的区域索引，以确定所述相邻的至少两个资源分区聚合后所使用的区域索引与所述第二信号单元中资源分区所使用的区域索引不产生通信干扰；当所述第二信号单元中靠近所述边界处的资源分区未进行聚合时，确定所述相邻的至少两个资源分区聚合后所使用的区域索引与所述第二信号单元中资源分区所使用的区域索引不产生通信干扰；当所述第二信号单元中靠近所述边界处的资源分区聚合后的新的资源分区所使用的区域索引与所述相邻的至少两个资源分区中每个资源分区的区域索引不相同时，确定所述相邻的至少两个资源分区聚合后所使用的区域索引与所述第二信号单元中资源分区所使用的区域索引不产生通信干扰。
然后，将待聚合的资源分区的区域索引带入函数

，进而得到聚合后的新的资源分区的区域索引。其中，可以将资源分区的区域索引的聚合过程定义为一个函数△，

分别为聚合后的新的资源分区的

和

。
可选的，在确定所述相邻的至少两个资源分区聚合后的区域分布参数之前，可以判断所述相邻的至少两个资源分区聚合后得到的新的资源分区的资源利用率是否大于第二预设阈值；若所述新的资源分区的资源利用率不大于所述第二预设阈值，则执行所述确定所述相邻的至少两个资源分区聚合后的区域分布参数的操作步骤；若所述新的资源分区的资源利用率大于所述第二预设阈值，则对所述相邻的至少两个资源分区不进行聚合。
S310，第一基站向车载终端发送携带有区域分布参数的广播消息。
具体实现中，如果车载终端在所述相邻的至少两个资源分区聚合后新的资源分区内，则第一基站可以向车载终端发送携带有所述相邻的至少两个资源分区聚合后的新的资源分区的区域分布参数的广播消息，如果车载终端在其他没有聚合的资源分区内，则第一基站可以向车载终端发送未聚合的资源分区的区域分布参数的广播消息，其中，区域分布参数可以包括计算区域索引所需的哈希函数以及哈希函数中的计算参数。
S311，车载终端根据所述区域分布参数和预先获取的地理位置确定所述车载终端所在的资源分区的区域索引并使用该区域索引对应的资源池。其中，地理位置可以包括地理坐标。
具体实现中，如果车载终端在所述相邻的至少两个资源分区聚合后新的资源分区内，车载终端可以将计算参数和地理坐标代入聚合后的新的资源分区的哈希函数中，从而得到车载终端所在聚合后的新的资源分区的区域索引，并使用该区域索引对应的资源池。
在本发明实施例中，首先获取第一信号单元中每个资源分区的资源利用率；然后判断第一信号单元中是否存在相邻的至少两个资源分区中每个资源分区的资源利用率小于第一预设阈值；其次若存在，确定相邻的至少两个资源分区聚合后所使用的区域索引是否与邻近的第二信号单元中资源分区所使用的区域索引产生通信干扰；若不产生通信干扰，确定相邻的至少两个资源分区聚合后的区域分布参数；最后向车载终端发送携带有区域分布参数的广播消息，车载终端接收到广播消息之后，根据区域分布参数和预先获取的地理位置确定车载终端所在的资源分区的区域索引并使用该区域索引对应的资源池，从而提高资源利用率。
请参考图10，图10是本发明实施例提供的一种资源分区聚合装置的结构示意图。如图所示，本发明实施例中的装置包括：
信息获取模块1001，设置为获取第一信号单元中每个资源分区的资源利用率。
具体实现中，在第一基站覆盖的第一信号单元划分为多个资源分区，并使用不同的区域索引对多个资源分区进行标识，如图4所示，seNB（第一基站）覆盖的第一信号单元包括4×4个资源分区，资源分区分别使用（0，0）、（0，1）、……、（3，3）等区域索引进行标注，同样NeNB（第二基站）覆盖的第二信号单元也包括4×4个资源分区，资源分区分别使用（0，0）、（0，1）、……、（3，3）等区域索引进行标注，由于靠近两个信号单元之间的交界处的两个资源分区分别使用不同的区域索引，因此不会产生通信干扰。另外，由于每个资源分区中的车载终端的数量不同，因此每个资源分区的资源利用率也不相同，如果某个资源分区中的车载终端的数量的越多，则该资源分区的资源利用率越高，可以实时监控每个资源分区中信号传输数量进而获取每个资源分区的资源利用率。
资源判断模块1002，设置为判断所述第一信号单元中是否存在相邻的至少两个资源分区中每个资源分区的资源利用率小于第一预设阈值。
具体实现中，如果所述第一信号单元中不存在相邻的至少两个资源分区中每个资源分区的资源利用率小于第一预设阈值，则对第一信号单元中的资源分区不需要进行聚合。
干扰确定模块1003，设置为若存在，确定所述相邻的至少两个资源分区聚合后所使用的区域索引是否与邻近的第二信号单元中资源分区所使用的区域索引产生通信干扰。
具体实现中，判断所述至少两个资源分区中每个资源分区是否靠近所述第一信号单元与所述第二信号单元之间的边界处；若不靠近所述边界处，则确定所述相邻的至少两个资源分区聚合后所使用的区域索引与所述第二信号单元中资源分区所使用的区域索引不产生通信干扰。
如图5所示，区域索引（1，2）对应的资源分区和区域索引（2，2）对应的资源分区的资源利用率均小于第一预设阈值，则可以判断区域索引（1，2）对应的资源分区或区域索引（2，2）对应的资源分区是否靠近第一信号单元与第二信号单元之间的边界处。区域索引（1，2）对应的资源分区和区域索引（2，2）对应的资源分区不靠近所述边界处，因此区域索引（1，2）对应的资源分区和区域索引（2，2）对应的资源分区聚合后，与第二信号单元中的资源分区不会产生通信干扰，因此第一基站不需要与第二信号单元所属的第二基站进行交互。
可选的，可以首先判断所述至少两个资源分区中每个资源分区是否靠近所述第一信号单元与所述第二信号单元之间的边界处；若靠近所述边界处，则向所述第二信号单元所属的基站发送所述相邻的至少两个资源分区中每个资源分区的区域索引。
如图6所示，区域索引（1，2）对应的资源分区和区域索引（1，3）对应的资源分区需要聚合，但区域索引（1，3）对应的资源分区靠近第一资源分区和第二资源分区的边界处，由于区域索引（1，2）对应的资源分区和区域索引（1，3）对应的资源分区聚合后的新的资源分区可能与第二资源分区中靠近所述边界处的资源分区使用相同的区域索引，因此，第一基站需要与第二信号单元所属的第二基站进行交互，向第二基站发送所述相邻的至少两个资源分区中每个资源分区的区域索引。
如图7所示，区域索引（3，2）对应的资源分区和区域索引（1，3）对应的资源分区需要聚合，但这两个资源分区分别与其他两个信号单元（第二信号单元和第三信号单元）接壤，由于区域索引（3，2）对应的资源分区和区域索引（3，3）对应的资源分区聚合后的新的资源分区可能与其他两个信号单元中靠近边界处的资源分区使用相同的区域索引，因此，第一基站需要同时与其他两个信号单元所属的基站进行交互，分别向第二基站和第三基站发送所述相邻的至少两个资源分区中每个资源分区的区域索引。
然后，第二基站接收到所述相邻的至少两个资源分区中每个资源分区的区域索引之后，确定所述第二信号单元中靠近所述边界处的资源分区所使用的区域索引是否与所述相邻的至少两个资源分区中每个资源分区的区域索引相同并返回聚合指示信息；第一基站根据所述指示信息，确定所述相邻的至少两个资源分区聚合后所使用的区域索引是否与所述第二信号单元中资源分区所使用的区域索引产生通信干扰。
如图6所示，由于第二信号单元中资源分区没有进行聚合，而第一信号单元中的区域索引（1，2）对应的资源分区和区域索引（1，3）对应的资源分区聚合后的新的资源分区所使用的区域索引可能为（1，2）或（1，3），与边界处的第二信号单元中区域索引（1，0）不相同，因此确定所述相邻的至少两个资源分区聚合后所使用的区域索引与所述第二信号单元中资源分区所使用的区域索引不产生通信干扰。
如图8所示，第二信号单元中靠近边界处的区域索引（1，1）对应的资源分区和区域索引（1，2）对应的资源分区进行了聚合，聚合后的新的资源分区的区域索引为（1，1），而第一信号单元中区域索引（1，2）对应的资源分区和区域索引（1，3）对应的资源分区聚合后的新的资源分区所使用的区域索引可能为（1，2）或（1，3），因此，第二信号单元中靠近所述边界处的资源分区聚合后的新的资源分区所使用的区域索引与所述相邻的至少两个资源分区中每个资源分区的区域索引不相同，因此第二基站通知第一基站所述第二信号单元中靠近所述边界处的资源分区聚合后的新的资源分区所使用的区域索引与所述相邻的至少两个资源分区中每个资源分区的区域索引不相同。
如图9所示，第二信号单元中靠近边界处的区域索引（1，1）对应的资源分区、区域索引（1，2）对应的资源分区、区域索引（1，3）对应的资源分区进行了聚合，聚合后的新的资源分区的区域索引为（1，2），而第一信号单元中的区域索引（1，2）对应的资源分区和区域索引（1，3）对应的资源分区聚合后的新的资源分区所使用的区域索引可能为（1，2）或（1，3），因此第二信号单元中靠近所述边界处的资源分区聚合后的新的资源分区所使用的区域索引（1，2）与第一信号单元中聚合后的新的资源分区所使用的区域索引（1，2）相同，如果所述相邻的至少两个资源分区聚合后的新的资源分区使用区域索引（1，2），则与所述第二信号单元中资源分区所使用的区域索引产生通信干扰，因此，第二基站需要通知第一基站所述第二信号单元中靠近所述边界处的资源分区聚合后的新的资源分区所使用的区域索引与所述相邻的至少两个资源分区中目标资源分区所使用的区域索引相同。
如图7所示，第二信号单元中靠近边界处的区域索引（3，0）对应的资源分区、区域索引（3，1）对应的资源分区、区域索引（3，2）对应的资源分区进行了聚合，聚合后的新的资源分区的区域索引为（3，2），第三信号单元中靠近边界处的（0，2）对应的资源分区、区域索引（1，2）对应的资源分区、区域索引（2，2）对应的资源分区进行了聚合，聚合后的新的资源分区的区域索引为（0，2），而第一信号单元中区域索引（3，2）对应的资源分区和区域索引（3，3）对应的资源分区聚合后的新的资源分区可能使用相同的区域索引（3，2）或（3，3），因此第二信号单元中靠近所述边界处的资源分区聚合后的新的资源分区所使用的区域索引（3，2）与第一信号单元中的聚合后的新的资源分区所使用的区域索引（3，2）相同，而第三信号单元中靠近所述边界处的资源分区聚合后的新的资源分区所使用的区域索引与所述相邻的至少两个资源分区中每个资源分区的区域索引均不相同，第二信号单元所属的第二基站需要通知第一基站所述第二信号单元中靠近所述边界处的资源分区聚合后的新的资源分区所使用的区域索引与所述相邻的至少两个资源分区中目标资源分区所使用的区域索引相同，第三信号单元所属的第三基站通知第一基站所述第二信号单元中靠近所述边界处的资源分区聚合后的新的资源分区所使用的区域索引与所述相邻的至少两个资源分区中每个资源分区的区域索引不相同。
参数确定模块1004，设置为若不产生通信干扰，确定所述相邻的至少两个资源分区聚合后的区域分布参数。
具体实现中，可以根据所述聚合指示信息，确定所述相邻的至少两个资源分区聚合后所使用的区域索引是否与所述第二信号单元中资源分区所使用的区域索引产生通信干扰。
进一步的，如果所述聚合指示信息包括所述第二信号单元中靠近所述边界处的资源分区聚合后的新的资源分区所使用的区域索引与所述相邻的至少两个资源分区中目标资源分区所使用的区域索引相同，去除所述相邻的至少两个资源分区中所述目标资源分区所使用的区域索引，以确定所述相邻的至少两个资源分区聚合后所使用的区域索引与所述第二信号单元中资源分区所使用的区域索引不产生通信干扰；当所述第二信号单元中靠近所述边界处的资源分区未进行聚合时，确定所述相邻的至少两个资源分区聚合后所使用的区域索引与所述第二信号单元中资源分区所使用的区域索引不产生通信干扰；当所述第二信号单元中靠近所述边界处的资源分区聚合后的新的资源分区所使用的区域索引与所述相邻的至少两个资源分区中每个资源分区的区域索引不相同时，确定所述相邻的至少两个资源分区聚合后所使用的区域索引与所述第二信号单元中资源分区所使用的区域索引不产生通信干扰。
然后，将待聚合的资源分区的区域索引带入函数

，进而得到聚合后的新的资源分区的区域索引。其中，可以将资源分区的区域索引的聚合过程定义为一个函数△，

可选的，在确定所述相邻的至少两个资源分区聚合后的区域分布参数之前，可以判断所述相邻的至少两个资源分区聚合后得到的新的资源分区的资源利用率是否大于第二预设阈值；若所述新的资源分区的资源利用率不大于所述第二预设阈值，则执行所述确定所述相邻的至少两个资源分区聚合后的区域分布参数的操作步骤；若所述新的资源分区的资源利用率大于所述第二预设阈值，则对所述相邻的至少两个资源分区不进行聚合。
消息发送模块1005，设置为向车载终端发送携带有区域分布参数的广播消息，所述广播消息用于指示所述车载终端根据所述区域分布参数和预先获取的地理位置确定所述车载终端所在的资源分区的区域索引并使用该区域索引对应的资源池。
具体实现中，如果车载终端在所述相邻的至少两个资源分区聚合后新的资源分区内，则第一基站可以向车载终端发送携带有所述相邻的至少两个资源分区聚合后的新的资源分区的区域分布参数的广播消息，如果车载终端在其他没有聚合的资源分区内，则第一基站可以向车载终端发送未聚合的资源分区的区域分布参数的广播消息，其中，区域分布参数可以包括计算区域索引所需的哈希函数以及哈希函数中的计算参数。车载终端接收到广播消息之后，可以将计算参数和地理坐标代入聚合后的新的资源分区的哈希函数中，从而得到车载终端所在聚合后的新的资源分区的区域索引，并使用该区域索引对应的资源池。
