Abstract:
A vehicle-to-everything (V2X) communication system, and method of communication in the V2X communication system is provided. The method includes: selecting, at a first V2X device, a control channel of a control channel resource pool; transmitting, on the selected control channel, sidelink control information (SCI) to a second V2X device; monitoring, at the first V2X device, an SCI acknowledgement (SCI-ACK) resource pool for an SCI-ACK indicator (SCI-ACK-IND) corresponding to the transmitted SCI; and in response to receiving a positive SCI-ACK-IND corresponding to the transmitted SCI, transmitting data to the second V2X device in a data resource pool according to the SCI.
