Abstract
In a wireless communication system, an APM provides sequential numbers to channels formed by dividing a specific frequency band, selects the channels in bit-reversed order of the numbers to divide the channels in frequency groups, creates a small hopping table for each frequency group, and generates a hopping table using the plurality of small hopping tables, and an AP performs channel access to a STA by frequency hopping with reference to the hopping table.
