<P>PROBLEM TO BE SOLVED: To provide a vehicle-to-vehicle communication system that reduce limitation in a downlink data amount from a base station to a mobile station and also suppress interference with transmission data in vehicle-to-vehicle communication. <P>SOLUTION: A vehicle-to-vehicle communication device 220 connected with a wide-area communication terminal 210 determines narrow-area communication resource allocation by use of wide-area communication resource allocation allocated to the wide-area communication terminal 210. Because in the wide-area communication resource allocation, a plurality of terminals are not allocated the same resource block, the narrow-area communication resource allocation determined by use of the wide-area radio communication resource allocation is also able to suppress a situation in which a plurality of terminals are allocated the same time slot. In addition, the wide-area communication resource allocation is necessary by nature for a base station communication device 100 and a terminal to communicate with each other, and because the narrow-area communication resource allocation is determined using the wide-area communication resource allocation necessary by nature, limitation in the downlink data amount is also reduced. <P>COPYRIGHT: (C)2013,JPO&INPIT |
