Patent ID: 8509142

Claim:
A method for detecting a resource indication value (RIV) indicating a start index (S) of consecutive virtual resource blocks (VRBs) and a length (L) of the consecutive VRBs in a wireless mobile communication system, the method comprising: receiving downlink control information including resource block allocation information, wherein the downlink control information is common information for plural users; and detecting the resource indication value (RIV) from the resource block allocation information, wherein, if Y−1≦└X/2┘, the resource indication value (RIV) is denoted by RIV=X(Y−1)+Z, or else the resource indication value (RIV) is denoted by RIV=X(X−Y+1)+(X−1−Z), where X is denoted by X=└N VRB /G┘, Y is denoted by Y=L/G, and Z is denoted by Z=S/G, in which, L is the length of the consecutive virtual resource blocks (VRBs), S is the start index of the consecutive virtual resource blocks (VRBs), N VRB is the number of virtual resource blocks (VRBs), L is a multiple of G, S is a multiple of G, and G is a natural number that is equal to or larger than 2.
