Abstract:
1. A method of allocating a radio resource in a wireless access system, the method performed by a base station and comprising: transmitting a first uplink MAP message, the first uplink MAP message including a first persistent uplink MAP information element (IE), the first persistent uplink MAP IE comprising first resource allocation information for persistently allocating a first resource allocation region for transmitting uplink data and first acknowledgment (ACK) information indicating a first ACK transmission region allocated for an ACK message related to the first persistent uplink MAP IE; receiving an ACK message indicating whether the first uplink MAP message including the first persistent uplink MAP IE is successfully received via the first ACK transmission region; and receiving uplink data via the first resource allocation region, wherein the first resource allocation information includes at least an orthogonal frequency division multiplexing access (OFDMA) symbol offset, a subchannel offset, or OFDMA slot information that indicates the first resource allocation region.
