Embodiment Construction

[0037] Before describing the present invention in detail, its outline will be described. Embodiments of the present invention relate to a communication system that performs vehicle-to-vehicle communication between terminal devices mounted on a vehicle and also performs road-to-vehicle communication from a base station device installed in an intersection or the like to a terminal device. As vehicle-to-vehicle communication, a terminal device broadcasts and transmits a packet signal containing information such as a vehicle's speed and position (hereinafter, these are referred to as "data"). In addition, other terminal devices receive the packet signal, and recognize the approach of the vehicle and the like based on the data. Here, the base station apparatus repeatedly specifies a frame including a plurality of subframes. The base station apparatus selects any one of a plurality of subframes for road-to-vehicle communication, and broadcasts and transmits a packet signal containi...

Abstract

A base station device (1010) controls inter-terminal communication. Basic information in which information relating to a first period is included and extended information in which information relating to a second period and a third period is included are defined, and a generation unit (1046) generates a packet signal in which an identifier for identifying that the basic information out of the basic information and the extended information is included in the packet signal or that the basic information and the extended information are included in the packet signal is included. A modulation / demodulation unit (024) and an RF unit (022) report the packet signal in which the identifier generated in the generation unit (1046) is included.

Description

technical field [0001] The present invention relates to a communication technology, and in particular, to a base station apparatus for transmitting and receiving signals including predetermined information. Background technique [0002] In order to prevent head-on collisions at intersections, research on road-to-vehicle communication is underway. In road-to-vehicle communication, information on the status of an intersection is communicated between a roadside device and an in-vehicle device. In the road-to-vehicle communication, it is necessary to install the roadside equipment, which increases the time and cost. On the other hand, in the case of vehicle-to-vehicle communication, that is, a system in which information is communicated between in-vehicle devices, installation of roadside devices is not required. In this case, for example, the current position information is detected in real time by GPS (Global Positioning System) etc., and the position information is exchange...
