In this paper, we investigate multicast transmit
beamforming for vehicle to everything (V2X) communication
employing LTE´s multimedia broadcast single-frequency network
(MBSFN) capabilities. LTE-MBSFN enables to broadcast/
multicast information in 4G networks, which can be utilized
for efficient dissemination of road traffic related information to
vehicles on highways/motorways. MBSFN is currently restricted
to single antenna transmission within the LTE standard; this
paper aims to present performance benefits obtained with the
introduction of multiple transmit antennas. We propose an
efficient multi-cell multicast beamforming technique that leads
to significant SINR improvements, which enhances reliability,
reduces transmission latency and facilitates achieving 5G requirements
for vehicular communications.
