In a vehicle-to-vehicle communication system, an intersection-located road side unit (RSU) having two omni-antennas applies spatial filtering to the antennas' RX signals to recover first and second overlapping basic safety messages (BSMs) concurrently transmitted by two intersection-approaching vehicles that have no direct line of sight (NLOS) between them. The RSU retransmits each BSM for receipt by the other vehicle using either an omnidirectional retransmission technique in which the two messages are sequentially transmitted using an omnidirectional beam-pattern, a directional retransmission technique in which the two messages are sequentially transmitted using directional beam-patterns, or an XOR retransmission technique in which the RSU applies an XOR operation to the two BSMs and transmits the resulting XOR message using an omnidirectional beam-pattern. A receiving vehicle can apply an XOR operation to the XOR message and a local copy of the first BSM message to recover the second BSM message.
