Apparatus and method for reducing volume of resource allocation information message in a broadband wireless communication system

A method performed by a mobile station (MS) in a wireless communication system, the method comprising:

• receiving a first message, broadcasted by a base station, including information indicating a first periodicity and a first offset of an uplink control channel for a first initial network entry;
• transmitting, to the base statioin, an uplink signal for the first initial network entry through the uplink control channel that is identified based on the first periodicity and the first offset;
• receiving, transmitted by the base station, a seond message including second information indicating a second periodicity and a second offset of the uplink control channel for a second initial network entry, the second periodicity being different from the first periodicity and the second offset being different from the first offset;
• and
• transmitting, to the base station, an uplink signal for the second initial network entry through the uplink control channel that is identified based on either the first periodicity and the first offset or the second periodicity and the second offset,
• wehrein a periodicity is a frame interval between two frames including the uplink control channel,
• wherein an offset is a start point of the periodicity, and
• wherein the periodicity and the offset are defined by number of frames.

A base station in a wireless communication system, the base station comprising:

• a transceiver;
• and
• at least one processor is coupled to the transceiver and configured to:
• broadcast, to a plurality of mobile stations (MSs), a first message including first information indicating a first periodicity and a first offset of an uplink control channel for a first initial network entry,
• receive, from one MS of the plurality of MSs, an uplink signal for the first initial network entry through the uplink control channel that is identified based on the first periodicity and the first offset,
• transmit, to the one MS, a second message including second information indicating a second periodicity and a second offset of the uplink control channel for a second initial network entry, the second periodicity being different from the first periodicity and the second offset being different form the first offset, and
• receive, from the one MS, an uplink signal for the second initial network entry through the uplink control channel that is identified based on either the first periodicity and the first offset of the second periodicity and the second offset,
• wherein a periodicity is a frame interval between two frames including the uplink control channel,
• wherein an offset is a start point of the periodicity, and
• wherein the periodicity and the offset are defined by number of frames.
