Adaptive Beam based Communication System and Multi-hop Relay Transmission Method Thereof

摘要

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.
