Abstract: PURPOSE: An adaptive beam based communication system and multi-hop relay transmission method are provided to increase the capacity of a communication system by transmitting data to a target vehicle through a multi-hop transmission method. CONSTITUTION: Infrastructure schedules a target vehicle which transmits data. A communication state of the target vehicle is determined(S120). The target vehicle receives the data through a directing transmission method which directly transmits the data or a multi-hop transmission method according to determination results. The multi-hop transmission method transmits the data to a relay vehicle selected from other vehicles. The relay vehicle transmits the data to the target vehicle. The relay vehicle is existed within a service area of the infrastructure and is not scheduled.
Abstract translation: 目的：提供一种基于自适应波束的通信系统和多跳中继传输方法，通过多跳传输方式向目标车辆发送数据，提高通信系统的容量。 规定：基础设施安排传输数据的目标车辆。 确定目标车辆的通信状态（S120）。 目标车辆通过根据确定结果直接发送数据或多跳传输方法的定向传输方法来接收数据。 多跳传输方法将数据发送到从其他车辆中选择的中继车辆。 继电器车辆将数据发送到目标车辆。 继电器车辆存在于基础设施的服务区域内，未安排。

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: 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。
