Abstract:
1. A wireless communication apparatus having a function of relaying data communications among stations included in a basic service set in an environment under which first and second standards of a wireless network using the same frequency band are existent in mixed form, said wireless communication apparatus comprising: reception detecting means for detecting reception of data based on the first and second standards; transmission detecting means for detecting transmission of the data based on the first and second standards; and control means for controlling said reception detecting means and said transmission detecting means, wherein said control means includes signal generating means for generating a self-destined transmit enabling signal including a set time based on either of the first and second standards, of transmit enabling signals, and time monitoring means for controlling generation of the self-destined transmit enabling signal, wherein said time monitoring means includes beacon transmitting means for transmitting beacons based on the first and second standards, and time monitoring means for monitoring elapse of the set times corresponding to the first and second standards and generating and outputting transmission control signals for transmitting the beacons according to the elapse of the set time, and wherein said control means further includes averaging means for averaging times used for transmission and reception, based on the first and second standards respectively, comparing means for determining which one of the averaged times for transmission and reception is large and obtaining a difference between the times as comparative information, and time deciding means for increasing and decreasing the comparative information at a predetermined rate relative to the present rate according to whether the comparative information is larger than a predetermined value to determine set times and outputting the same to said time monitoring means.
