Methods and systems for transmission of multiple modulated signals over wireless networks

摘要

A method and apparatus for requesting and allocating bandwidth in a broadband wireless communication system. The inventive method and apparatus includes a combination of techniques that allow a plurality of CPEs to communicate their bandwidth request messages to respective base stations. The CPE is responsible for distributing the allocated uplink bandwidth in a manner that accommodates the services provided by the CPE. By using a combination of bandwidth allocation techniques, the present invention advantageously makes use of the efficiency benefits associated with each technique.

主权项

1. A method of operating a wireless cellular mobile unit registered with a base station in a bandwidth on demand wireless cellular communication system, the method comprising:
transmitting from the wireless cellular mobile unit a one bit message requesting to be provided an allocation of uplink (UL) bandwidth in which to transmit a bandwidth request for at least one connection served by the wireless cellular mobile unit; receiving at the wireless cellular mobile unit the allocation of UL bandwidth in which to transmit the bandwidth request, the allocation of UL bandwidth received pursuant to the one bit message; transmitting from the wireless cellular mobile unit the bandwidth request within the allocation of UL bandwidth, the bandwidth request being indicative of a pending amount of UL data associated with the at least one connection; receiving at the wireless cellular mobile unit an UL bandwidth grant for the wireless cellular mobile unit, the UL bandwidth grant received pursuant to the bandwidth request; and allocating the received UL bandwidth grant to at least two UL connections served by the wireless cellular mobile unit, based on a QoS parameter of the at least two UL connections.
