ABSTRACT:
Various embodiments of the invention may take advantage of persistent scheduling in a wireless network to achieve efficiencies of operation. One embodiment dynamically adjusts the duration of persistent scheduling based on changing channel conditions. When mobile stations are grouped together for persistent scheduling, another embodiment uses a bitmap to indicate which mobile stations in the group have data in the current frame. Still another embodiment eliminates the Connection Identifier from a packet header when bitmaps are being used.
