    Abstract: Voice over IP (VoIP) packet header compression is performed for voice packets to be transmitted through a wireless channel. In at least one embodiment, packet headers are compressed to a fixed size that does not change based on channel conditions. In this manner, packet scheduling may be performed in the network in a reliable and efficient manner.

    Abstract: An embodiment of the present invention provides a method, comprising reducing overhead in OFDMA based Wireless Networks by determining the highest CIDs to be transmitted in a particular DL/UL MAP and determining the number of leading zero bits of the highest CID and removing the leading zero bits from each CID prior to transmission. Further, an embodiment of the present invention provides removing the CID field in the header of the message identified by a particular CID.

    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 translation: 在实施恒定比特率（CBR）实时（RT）分组应用时，通过利用分组分片来增强基于OFDMA的无线信道中的子信道化增益。 通常将在单个OFDMA帧中使用多个子信道发送的分组可以被分段并通过多个帧通过无线信道传送。 由于在每个帧内使用较少的子信道，增强了子信道化增益。

    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.
