Patent ID: 10827325

Abstract:
An operation method of a terminal in a V2X communication system may include: transmitting, by the terminal, a first radio resource control (RRC) message to a base station supporting a first radio access technology (RAT), the first RRC message including information indicating that the terminal supports multiple RATs including at least a first RAT and a second RAT; receiving, by the terminal, a second RRC message from the base station, the second RRC message including information indicating that multi-RAT based operations are allowed; transmitting, by the terminal, a resource request message for requesting resource allocation for V2X communication to an access point supporting the second RAT when a channel busy ratio (CBR) measurement result is greater than or equal to a CBR threshold in a channel configured by the base station; receiving, by the terminal, from the access point a resource allocation message including resource allocation information in response to the resource request message; and transmitting, by the terminal, data to the access point using a radio resource indicated by the resource allocation message.
