Four way handshake for robust channel estimation and rate prediction
First Claim
Patent Images
1. A method of wireless communication that estimates channel interference, comprising:
- sending a request;
receiving a grant of a channel assignment responsive to the request;
sending a pilot utilizing the granted channel assignment;
receiving a rate assignment based on a signal to interference noise ratio; and
transmitting data at the assigned rate.

Abstract
Systems and methodologies are described that facilitate enabling communication over a time varying channel with time varying interference. According to various aspects, systems and methods are described that facilitate selecting appropriate channels and identifying rates that yield optimal capacity for the selected channels. Such systems and/or methods can evaluate a signal to interference noise ratio (SINR) at a receiving node within a multinode network to facilitate selecting the rates.
