SIGNALING TO APPLICATION LACK OF REQUESTED BANDWIDTH

摘要

A system for signaling an application when a requested data rate and Quality of Service cannot be achieved using OFDM wireless data transmission, and the application proceeds by either renegotiating QoS and data rate, or waiting until they requested rate and QoS are met.

1. A method performed on a computing device, the method comprising:
receiving, by the computing device, a serial digital data stream; converting, by the computing device, the received serial digital data stream into a plurality of parallel digital data streams; modulating, by the computing device, each of the plurality of parallel digital data streams onto a separate subchannel, where each separate subchannel is one of a plurality of subchannels of a channel, where the separate subchannels are selected based on a requested data transmission rate and on noise levels detected on various of the plurality of subchannels, the modulating resulting in modulated parallel digital data streams; converting, by the computing device, the modulated parallel digital data streams into a modulated serial digital data stream; converting, by the computing device, the modulated serial digital data stream into a modulated analog data stream that represents the received serial digital data stream; and transmitting, by the computing device, the modulated analog data stream.
