Abstract
The present invention increases, even while transmission rights are not being allocated to respective radio communication terminals, a maximum number of simultaneous connections within a communication capacity range of a communication frequency set in advance, reduce a waiting time, and increase speed of communication without causing an increase in cost for addition of radio base stations, replacement with a high-performance model, and the like. A radio base stationcalculates a guard time based on beacon transmission timing from a difference between reference times in beacon transmission, and transmission and reception time frame information based on beacon transmission timing of a radio base station. In other words, the radio base stationcalculates a guard time based on beacon transmission timing to prevent overlap of a transmission and reception time frame of transmission and reception to and from a radio communication terminalbelonging to the radio base station, and transmission and reception timing of transmission and reception to and from a radio communication terminalbelonging to the radio base station
