Abstract
In this paper, we study a wireless communication network in which multiple mobile users located within a public transportation vehicle intend to send data to the serving base station. Due to the vehicle penetration loss (VPL), conventional direct uplink transmission may demand an unnecessarily high power level to reach a satisfactory communication performance. To address this issue we consider establishing cooperation among the vehicular users through the multiplexing-mode device-to-device (D2D) communication technique before their scheduled uplink transmissions. By these means the users can adopt simple space-time coding to jointly deliver their data, when the transmitter-side channel state information is not available. Via analytical and simulation results, we show that the proposed scheme can enhance the achievable energy efficiency over the conventional uplink transmission approach.
