    摘要: 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.

    摘要: 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.

    摘要: Techniques for determining a sleep area of a sleep group in a wireless communications network based on a value of a dynamically changing communication characteristic. In various embodiments, a sleep area may be determined to reduce resource use in a wireless communication network supporting a sleep mode of a mobile station. In one embodiment, the sleep area may be determined based on a speed of a mobile station.

    摘要: 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.
