Abstract

Official abstract text for this publication.

A method and apparatus for requesting and allocating bandwidth in a broadband wireless communication system. The method and apparatus includes a combination of techniques that allow a plurality of CPEs to communicate their bandwidth request messages to respective base stations. One technique includes a “polling” method whereby a base station polls CPEs individually or in groups and allocates bandwidth specifically for the purpose of allowing the CPEs to respond with bandwidth requests. The polling of the CPEs by the base station may be in response to a CPE setting a “poll-me bit” or, alternatively, it may be periodic. Another technique comprises “piggybacking” bandwidth requests on bandwidth already allocated to a CPE. Currently active CPEs request bandwidth using unused portions of uplink bandwidth that is already allocated to the CPE. The CPE is responsible for distributing the allocated uplink bandwidth in a manner that accommodates the services provided by the CPE.

First claim

Opening claim text (preview).

The invention claimed is: 1. A base station for communication with a plurality of wireless cellular mobile units connected in a wireless communication system, the base station comprising: a transmitter for transmitting downlink (DL) traffic to the wireless cellular mobile units; and a media access control (MAC) module executable by one or more processors and configured to identify an explicit message received from a wireless cellular mobile unit, indicating that the wireless ce…
