Abstract: Sub-channelization gain in an OFDMA-based wireless channel is enhanced by utilizing packet fragmentation when implementing a constant bit rate (CBR) real time (RT) packet application. A packet that would normally be transmitted using multiple sub-channels in a single OFDMA frame may be fragmented and delivered through the wireless channel over multiple frames. Because fewer sub-channels are used within each frame, sub-channelization gain is enhanced.

Abstract: Embodiments of systems and methods for arranging data units in a downlink burst transmission are generally described herein. Other embodiments may be described and claimed. In some embodiments a group of data units are arranged by associated identifiers. These identifiers may also be associated with certain subscriber stations. Once arranged, the data units may be transmitted in a downlink burst and received by a subscriber station. The subscriber station may determine the arrangement of the data units to decode until a cutoff value is determined and passed.

Abstract: A method for radio resource allocation based on planned priority ordering to realize the maximum carrier to interference ratio (C/I) in a cellular system that employs frequency reuse. Reuse of co-channel resources is progressively increased as traffic load increases based on the available spectrum. By using this method, interference rejection at light loading can approach that obtainable by using a low reuse factor. When applied to a wireless packet network, this method allows each resource to carry highest throughput according to the traffic demand and available bandwidth, while making more resources available to carry additional traffic when system loading is increased.
