Methods and Systems for Transmission of Multiple Modulated Signals Over Wireless Networks

A method of allocating bandwidth to subscriber units from a base station operating in a wireless communication system, comprising:

• detecting a bandwidth request in the uplink (UL) data received from a subscriber unit;
• identifying in the bandwidth request a requested amount of UL bandwidth pertaining to one or more of a plurality of UL queues at the subscriber unit;
• determining if the requested amount of bandwidth is available, and
• allocating to the subscriber unit an UL bandwidth grant based on the requested amount of bandwidth and the bandwidth available for the UL data, the UL bandwidth grant being for distribution between one or more connections by the subscriber unit.

A base station for a broadband wireless communication system which transmits downlink (DL) traffic to subscriber units and receives uplink (UL) traffic from the subscriber units, the base station comprising:

• a bandwidth request processing module for detecting a bandwidth (BW) request in the UL traffic received from a subscriber unit and identifying in the BW request a requested amount of UL bandwidth pertaining to a specified connection established at the subscriber unit;
• a media access arbiter for receiving the bandwidth request and granting said requested amount of bandwidth, if available;
• and
• a processor adapted to maintain a downlink map and an uplink map with downlink and uplink bandwidth allocations respectively, dynamically update said map to account for current bandwidth allocations, and provide the updated DL and UL to the subscriber units.
