Mini-slot confirmation channel transmission in V2V communications

Abstract

A network configures (e.g., allocates) reservation channel resources within a reservation channel resource pool, comprising at least one time-slot comprising a set of mini-slots, and transmits information regarding the reservation channel resource pool to at least one wireless communication device of a vehicle ad-hoc network. A wireless communication device interested in transmitting a reservation channel transmission selects, from the reservation channel resource pool, time-frequency resources for a reservation channel transmission. The wireless communication device also selects a number of mini-slots over which to repeatedly transmit the reservation channel transmission. The wireless communication device repeatedly transmits the reservation channel transmission over the selected number of mini-slots, using the selected time-frequency resources. In response to the reservation channel transmissions, at least one other wireless communication device transmits, to the wireless communication device, one or more confirmation channel transmissions, each of which are repeatedly transmitted over a second number of mini-slots.
