Patent ID: 8565262

Claim:
A frequency reusing method in a wireless communication system including a coverage region, which has first, second, and third regions, the method comprising: (a) measuring a carrier to interference and noise ratio (CINR) from a communication signal; (b) comparing the CINR with a first threshold value while a first scheme is being performed and comparing the CINR with a second threshold value while a second scheme is being performed, thereby determining a frequency reuse plan, wherein said first scheme corresponds to a first frequency reuse factor, said second scheme corresponds to a second frequency reuse factor, said second frequency reuse factor higher than said first frequency reuse factor; (c) transmitting traffics by assigning a total frequency band, which includes three different sub-frequency bands, to the first, second, and third regions during a first interval for the first scheme according to the frequency reuse plan; and (d) transmitting the traffics by respectively assigning the three different sub-frequency bands to the first, second, and third regions during a second interval for the second scheme according to the frequency reuse plan.
