In this paper, a frequency sharing with OFDMA (Orthogonal Frequency Division Multiple Access) is considered to be applied on road to vehicle communication (RVC) and inter-vehicle communication (IVC). However, it is difficult to accomplish precise frequency and timing synchronization in IVC. This leads to multiple access interference with the collapse of orthogonality among OFDMA subcarriers due to carrier frequency offset and symbol timing offset of IVC. This paper propose a frequency sharing scheduling to suppress the interference to RVC by selecting subcarriers and controlling power at IVC adaptively during the period allocating the time slot and the subcarrier of OFDMA to multiple pairs of RVC and IVC, respectively. Furthermore, the proposed scheduling method can give the appropriate priority to IVC for traffic safety on frequency sharing system. |
