Claim:
A method for mapping a system frequency band to subbands and minibands at a base station in a wireless communication system, the method comprising: dividing the system band frequency into a plurality of physical resource units (PRUs); mapping the plurality of PRUs to physical resource units of a subband PRU SB in accordance with a first rule; mapping the plurality of physical resource units to physical resource units of a miniband PRU MB in accordance with a second rule, wherein the first rule and the second rule contain factors for limiting a maximum value of a gap between subbands allocated to the system frequency band, wherein the first rule is PRU SB [j]=PRU[i], j=0, 1, . . . , L SB −1, where i is N 1 · { ⌈ N sub max ⁡ ( K SB , x ) ⌉ · ⌊ j N 1 ⌋ + ⌊ ⌊ j N 1 ⌋ · GCD ⁡ ( N sub , ⌈ N sub / max ⁡ ( K SB , x ) ⌉ ) N sub ⌋ } ⁢ mod ⁢ { N sub } + { j } ⁢ mod ⁢ { N 1 } (where, N 1 denotes the number of physical resource units configuring one subband, N sub denotes a maximum number of subbands, K SB denotes the number of subbands to be allocated, GCD(N sub ,┌N sub /max(K SB , x)┐) denotes a greatest common divisor of N sub and ┌N sub /max(K SB , x)┐, and x denotes a factor for limiting a maximum value of a gap between subbands).
