Radio communication system

摘要

In a radio communication system repeatedly using the same frequency, each base station and terminal station have directional antennas respectively, and a base station has direction-determining patterns for setting a direction of an antenna according to a timing, the adjacent base stations each using the same frequency use different direction-determining. patterns from each other, and remote base stations repeatedly use the same direction-determining patterns. The direction-determining pattern has a correlation between a timing obtained by equally dividing a frame for a communication line by a number of direction-determining patterns and each antenna direction, and a communication slot is allocated based on a timing decided according to the table to a communication line with a terminal station positioned at a particular direction.
