Adaptive Beamforming Scheme with Service Quality Assurance for Vehicle Communications Using Map Data

This paper proposes an adaptive beamforming scheme with service quality assurance for vehicle communications to provide reliable and stable data transmissions. In the proposed scheme, serving beams with variable beamwidth are adopted by base station (BS) to transmit signals due to the different path loss of different propagation distance. Additionally, an adaptive searching algorithm is developed in the scheme to optimize the beamwidth and directions of the serving beams. Theoretical analysis and simulations are conducted to prove the achievable reliability and stability performance.
