Abstract:
1. A frequency reusing method in a wireless communication system in which a radio access station (RAS) transmits information to portable subscriber stations (PSSs) in a coverage region of the RAS, the coverage region including first, second, and third regions, the method comprising: (a) transmitting the information to at least one PSS in the coverage region by assigning an identical frequency band to all of the first, second, and third regions during a first interval according to a frequency reuse plan; (b) transmitting the information to at least one PSS in the first region by assigning the identical frequency band to the first region during a second interval according to the frequency reuse plan; (c) transmitting the information to at least one PSS in the second region by assigning the identical frequency band to the second region during a third interval according to the frequency reuse plan; and (d) transmitting the information to at least one PSS in the third region by assigning the identical frequency band to the third region during a fourth interval according to the frequency reuse plan, wherein the frequency reuse plan is determined by comparing a carrier to interference and noise ratio (CINR) of each of the PSSs in the coverage region and a threshold value, wherein the identical frequency band is reused in the first, second, and third regions, and wherein the steps (a) to (d) are sequentially performed.
