Abstract: In order to consider an optimum control method and an optimum mounting method needed, a UWB having a communication function and a radar function are used. For an obstacle vehicle in front, the distance between two cars is measured using the radar function, and according to this distance, a hazard warning is issued to a driver or a pre-crash operation is carried out. Moreover, by informing its own position to each other between vehicles using the communication function, the distance to a vehicle near to the own vehicle is measured regardless of clutter, and according to this distance, a hazard warning is issued to a driver or a pre-crash operation is carried out. Moreover, the operating frequency and transmission power of a radar are changed based on its own location information, thereby reducing influence to and from other wireless system.

Abstract: A time slot for a connection request sent from a mobile station includes the mobile station ID and the application discrimination word of the object application for which the mobile station requests the connection. By referring to the database, a base station assigns a MDC preferentially to a mobile station issuing a connection request for calling a high priority application. The base station monitors the MDCs used for ongoing communications. If a MDC assigned to a mobile station does not satisfy a predetermined radio communication quality, other MDCs for lower priority application are freed and reassigned to the mobile station. A plurality of MDCs including the reassigned MDCs into which the same contents are encapsulated are transmitted to the mobile station.

Abstract: In calculation of a position of a terminal, there arises, when creating a delay profile, a problem to select a transmission code for a sector of a base station to create the delay profile. According to a position of a base station and a bearing of each antenna forming a sector of the base station, a wireless position calculation method selects a transmission code for a sector of a base station to create a delay profile. Under a condition that the number of delay profiles to be created is limited, each delay profile is created in consideration of the antenna bearing. Therefore, the number of base stations at mutually different positions is increased to calculate the position and precision of the position calculation is improved.

Abstract: A wireless communication system for high-speed motion use, capable of shortening the frequency channel search time and increasing the communication time available for service. The system includes an access point communicating on a designated one frequency channel and a mobile terminal communicating on the same received channel by receiving radio waves transmitted by the same access point. As for mobile terminal, in a storage, priority data is stored for a channel search in which arbitrary priorities can be set respectively for the channels. Frequency channel search sequence data, set up so that the number of times of appearance becomes greater for channels for which the priority data are set higher, are generated on the basis of the relative data, and a search of communication-capable channels is carried out in accordance with the same channel search sequence data.

Abstract: In a mobile communication using satellites, the present invention allows a mobile to receive a service wherever it is. To do so, when positioning the current location of a mobile using a satellite that sends the GPS signal, the mobile receives an electric wave directly from the satellite for performing positioning when the electric wave can be received directly from the satellite. On the other hand, when an electric wave cannot be received directly from the satellite, the mobile receives an electric wave from a pseudo-satellite or performs positioning using a wireless network between other mobiles and the mobile. Positioning may also be performed using an indoor wireless network.
