Claim:
A method for transmitting an uplink signal in a wireless communication system, the method comprising: receiving a control channel signal including resource allocation information, wherein the resource allocation information includes a combinatorial index r used to indicate two resource block sets, each of which includes one or more continuous resource block groups (RBGs); and transmitting the uplink signal using the two resource block sets, wherein the combinatorial index r is given by the following Equation: r = ∑ i = 0 M ′ - 1 ⁢ 〈 N - s i M ′ - i 〉 , ⁢ 〈 x y 〉 = { ( x y ) if ⁢ ⁢ x ≥ y 0 if ⁢ ⁢ x < y where, M′ is 4, N is the number of RBGs+1, {S i } =0 M′−1 satisfies 1≦s i ≦N and S i <S i+1 , s 0 and s 1 −1 indicate a starting RBG index and an ending RBG index, respectively, of a first resource block set of the two resource block sets, s 2 and s 3 −1 indicate a starting RBG index and an ending index, respectively, of a second resource block set of the two resource block sets, and ( x y ) represents x ⁡ ( x - 1 ) ⁢ ⁢ … ⁢ ⁢ ( x - y + 1 ) y ⁡ ( y - 1 ) ⁢ ⁢ … ⁢ ⁢ 1 .
