Abstract: PURPOSE: A vehicle communication system based on an infrastructure is provided to supply a traffic service. CONSTITUTION: Infrastructure vehicles are vehicles connected to an infrastructure. The vehicles are grouped based on interference due to a virtual beam(410). The virtual beam is formed for each vehicle. An index group is generated(420). An index is allocated to each vehicle. Currently available power is compared(430). The power of a beam which satisfies QoS about a first vehicle is calculated among vehicles corresponding to an index group. The power of the beam is compared with the currently available power. If the power of the beam is weaker than the currently available power, the power of a beam for a first vehicle is allocated.

Abstract translation: 目的：提供基于基础设施的车辆通信系统来提供交通服务。 规定：基础设施车辆是与基础设施相连的车辆。 基于虚拟梁（410）的干扰，车辆被分组。 为每个车辆形成虚拟梁。 生成索引组（420）。 索引被分配给每个车辆。 目前可用功率进行比较（430）。 在对应于索引组的车辆中计算满足关于第一车辆的QoS的波束的功率。 将光束的功率与当前可用功率进行比较。 如果光束的功率弱于当前可用功率，则分配用于第一车辆的光束的功率。

Abstract: PURPOSE: An infra in a vehicle communication system that is based on an infra base and a beginning connection method between vehicles are provided to minimize a resources that is used for a discovery beam. CONSTITUTION: Each of vehicles(320, 330) that enters to a service coverage of the infra(310) receives a discovery beam. Each of the vehicles selects one of mini slots according to a location of a contention slot that is included in the discovery beam. Each of the vehicles transmits own ID. The infra senses ID. The infra assigns an uplink resource about the vehicles that is corresponding to the ID.
Abstract translation: 目的：提供一种基于车辆基础的车辆通信系统和车辆之间的起始连接方法，以最小化用于发现梁的资源。 构成：进入下文（310）的服务覆盖范围的每个车辆（320,330）接收发现梁。 每个车辆根据包括在发现光束中的竞争时隙的位置来选择一个小时隙。 每个车辆发送自己的ID。 下面的感觉ID。 下行分配关于与ID相对应的车辆的上行链路资源。
