Claim:
A method for receiving data in a mobile communication system, the method comprising: receiving, by a wireless apparatus, control information including first information and second information, wherein the first information indicates one of two resource allocation types and the second information includes a bitmap indicating resource allocation; and receiving, by the wireless apparatus, the data using the control information, wherein: for a first resource allocation type of the two resource allocation types, a bit value of the bitmap indicates whether a corresponding resource block group (RBG) is allocated or not in consecutive RBGs; for a second resource allocation type of the two resource allocation types, third information in the control information indicates one of N RB sets, and a bit value of the bitmap indicates whether a corresponding resource block (RB) is allocated or not in the indicated RB set; the indicated RB set comprises a plurality of RBGs, in which neighboring RBGs are spaced by N−1 RBG(s); a size of RBG is N consecutive RBs; a size of RB is a predetermined number of consecutive subcarriers; and N is an integer equal to or greater than 2.
