CHANNEL ACCESS METHOD FOR VEHICLE COMMUNICATION HANDOVER
First Claim
1. A method for a plurality of roadside equipments to access a channel to support a vehicle communication handover, the method comprising:
- a first roadside equipment among the plurality of roadside equipments operating a transmitting/receiving mode in a control channel interval of an Nth synchronization interval;
a second roadside equipment neighboring to the first roadside equipment among the plurality of roadside equipments operating as a receiving mode in the control channel interval of the Nth synchronization interval;
the first roadside equipment operating as the receiving mode in a control channel interval of an (N+1)th synchronization interval; and
the second roadside equipment operating as the transmitting/receiving mode in the control channel interval of the (N+1)th synchronization interval.

Abstract
A first roadside equipment operates as a transmitting/receiving mode in a control channel interval of an Nth synchronization interval so as to support a handover. In this instance, a second roadside equipment neighboring to the first roadside equipment operates as a receiving mode in the control channel interval of the Nth synchronization interval. The first roadside equipment operates as the receiving mode in a control channel interval of an (N+1)th synchronization interval. In this instance, the second roadside equipment operates as the transmitting/receiving mode in the control channel interval of the (N+1)th synchronization interval.
