摘要： There are provided scheduling and a resend control system, which match simultaneous communications using a plurality of carriers. For individual carriers to be used, the simultaneous resend control of the carriers is made by notifying channel information and a data decoding result and by managing the resend numbers. Even in case the communications are performed by using the carriers simultaneously between a base station and a terminal, the scheduling can be done to contain the resend control. It is also possible to improve the communication quality and the throughput.

摘要： Even in areas where signals from only two or less base stations are available for position calculation, the mobile handset position can be calculated, expanding the position information service area and improving the usefulness. When the number of base stations available for position calculation is three or more, the position calculation is performed based on trilateration. When the number of available base stations is two or one, the position calculation is performed by using a two-station-based position calculation method or a one-station-based position calculation method according to the number of available base stations.

摘要： A coaxial resonant slot antenna having a novel structure is provided to further reduce the dimensions of radio terminals incorporating such an antenna. Also provided are a novel method of fabricating such a coaxial resonant slot antenna and a radio terminal having a novel structure using such a coaxial resonant slot antenna. An entire strip conductor is arranged inside a flat conductive cubic such that the strip conductor is insulated from the conductive cubic. A connection point between the strip conductor and a radio frequency transmission line is provided at a position about 1/4 of wavelength away from one end of the strip conductor. A slot is shaped into a narrow rectangle, a generally upside-down "U", or a generally upside-down "U" having another slot on each end. It is desired that the center slot crosses the strip conductor along the length thereof and in the height direction thereof, the distance between the ends being equivalent to about 1/2 of wavelength used. The radio terminal has a plurality of antennas associated with the present invention arranged on a plurality of surfaces and provides a connection mechanism for varying the number of antennas to be used in the talk mode and the standby mode.
