To meet the growing demand for wireless broadband communications in high-mobility cases, we study cell structures using millimeter-wave. Single antenna Cell (SC) and Linear Cell (LC) structures are here considered as typical approach. The cells in LC structures consist of strips while those in SC structures are circular. Distributed Antenna Cell (DAC) and Narrow Beamwidth Distributed Antenna Cell (NBDAC) have already been proposed for LC structures, but rigorous performance evaluations in high mobility case have not been conducted. Thus, in this paper, we compare the performances of SC, LC and NBDAC in a high-mobility environment. The comparison shows that NBDAC is the most suitable structure for high-mobility scenarios. In addition, we propose interference reduction methods for NBDAC to reduce adjacent cell interference and improve throughput at a cell edge. To evaluate effectiveness of the proposed methods, theoretical evaluations and computer simulations are conducted, and it is shown that NBDAC with the proposed methods can achieve 1Gbps throughput even in high-mobility environments. |
