Abstract:
Methods and apparatus for allocating a data region (termed “sticky region allocation”) in an orthogonal frequency-division multiplexing (OFDM) or orthogonal frequency division multiple access (OFDMA) frame so that a user terminal can receive/send data bursts for multiple OFDM/OFDMA frames, rather than inserting a MAP information element (MAP IE) for each user terminal in every frame, are provided. In this manner, the size of the control overhead, such as the downlink (DL) and uplink (UL) MAP messages, may be reduced. The reduced control overhead may increase the frame resources available for data traffic and thus, may boost the overall efficiency and performance of wireless systems using OFDM/OFDMA.
