MAP MESSAGE GENERATING METHOD AND APPARATUS FOR ENHANCING MAP COVERAGE IN A WIRELESS COMMUNICATION SYSTEM

摘要

An apparatus is provided for generating a MAP message in a wireless communication system supporting Orthogonal Frequency Division Multiple Access (OFDMA). The MAP message generation apparatus includes a controller for determining MAP Information Elements (IEs) to be included in MAP of a transmission frame, and controlling the MAP IEs to include Connection Identifier (CID) information and Modulation and Coding Scheme (MCS) level information; a Sub-MAP processor for comparing a total size of MAP IEs corresponding to the lowest MCS level in channel quality among the MAP IEs, with a preset maximum Forward Error Correction (FEC) block size, and grouping the MAP IEs into Sub-MAP groups having the maximum FEC block size according to the comparison result; and a Sub-MAP generator for generating Sub- MAP messages with the MAP IEs of the Sub-MAP groups.
