Description

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 station2acalculates 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 station2b. In other words, the radio base station2acalculates 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 terminal3belonging to the radio base station2b, and transmission and reception timing of transmission and reception to and from a radio communication terminal3belonging to the radio base station2a.
