Method for resource allocation for hybrid-automatic repeat request

A resource allocation method for a hybrid automatic repeat request (HARQ), the method comprising:

• receiving, by a mobile station, a media access protocol (MAP) message including specific information indicating whether or not differential allocation is supported,
• wherein MAP information contained in the MAP message is stored by the mobile station during predetermined frames;
• transmitting, by the mobile station, a non-acknowledgement (NACK) message to a base station, if there occurs any error in data packets received during the predetermined frames;
• and
• receiving, by the mobile station, sub-burst information, which includes differential allocation information related to sub-bursts for retransmitting the data packets, from the base station,
• wherein the differential allocation information includes information indicating
• a number of reference frames pre-transmitted for the sub-bursts in the predetermined frames,
• a reference frame offset from a frame transmitted for the sub-burst information based on the number of the reference frames,
• a number of reference sub-bursts, and
• a reference sub-burst index based on the reference frame offset and the number of reference sub-bursts, and
• wherein the sub-bursts are decoded using a decoding information included in the MAP information indicated by the differential allocation information.
