Claim:
A method of mapping a resource unit in a wireless communication system, the method comprising: obtaining L CRU,FPi (logical contiguous resource units in a frequency partition “i” (FPi)) indicating the number of contiguous resource units (CRUs) in the FPi and L DRU,FPi (logical distributed resource units in the FPi) indicating the number of distributed resource units (DRUs) in the FPi wherein 0≦i<FPCT, where FPCT denotes a frequency partition count; and mapping physical resource units (PRU) in the FPi (PRU FPi ) to CRUs in the FPi (CRU FPi ) by the L CRU,FPi , wherein L CRU,FPi is obtained based on L SB,FPi which indicates a number of subband based (SB-based) CRUs in the FPi and L MB,FPi which indicates a number of miniband-based (MB-based) CRUs in the FPi according to the following equation: L CRU , FPi = L SB , FPi + L MB , FPi , ⁢ where ⁢ ⁢ the ⁢ ⁢ L SB , FPi ⁢ ⁢ satisfies ⁢ ⁢ L SB , FP ⁢ ⁢ 0 = N 1 · CAS SB , 0 , ⁢ ⁢ where ⁢ ⁢ L SB , FPi = N 1 · min ⁢ { CASi , K SB , FPi } ⁢ ( herein , i > 0 ) ; where L MB , FPi = { 0 , CASi ≤ K SB , FPi ( CASi - K SB , FPi ) · N 1 , CASi > K SB , FPi , and where CASi denotes a number of SB-based CRUs and MB-based CRUs in the FPi (i>0) with an SB-sized granularity, K SB,FPi denotes a number of SBs in the FPi, CAS SB,0 denotes a number of SB-based CRUs in a primary FP (FP 0 ), N 1 denotes a number of PRUs included in an SB, and min{a,b} returns a smaller value between a and b.
