Abstract:
1. A method for transmitting MAP information by a base station in a communication system, the method comprising: acquiring channel quality information of each of a plurality of mobile stations; generating sub-MAPs, to which at least one of a coding scheme, a modulation scheme and a repetition scheme is applied, separately for each of the plurality of mobile stations according to the respective channel quality information; and transmitting a MAP message including the sub-MAPs on a plurality of subcarriers, wherein the sub-MAPs are uniformly distributed in all tiles included throughout an entire MAP region, each tile including a predetermined number of subcarriers and a predetermined number of symbol intervals, wherein the generating of the sub-MAPs comprises using at least one of a different modulation scheme and a different coding scheme for each sub-MAP information, wherein the MAP message includes a MAP header including size information of the sub-MAP and information on the number of the sub-MAPs, wherein the acquiring of the channel quality information comprises acquiring the channel quality information from each of the plurality of mobile stations over a channel quality information channel, and wherein the transmitting of the generated sub-MAPs comprises:
