Coordinating radio resource usage in unlicensed frequency bands

Abstract

A system and method for coordinating radio resource usage in an unlicensed frequency band (24) is provided. Specifically, under the present invention, a set of spectrum etiquette rules is provided that govern how radio systems (20A-C) operate within unlicensed frequency bands (24). In a typical embodiment, the set of spectrum etiquette rules can accommodate radio systems (20A-C) operating at varying channel bandwidths. To this extent, the set of spectrum etiquette rules generally includes: a channel switching rule; a bandwidth selection rule; a power selection rule; a deferring listen before talk (LBT) rule; a channelized LBT rule; and a synchronized LBT rule.

Description

technical field [0001] The present invention generally relates to systems and methods for coordinating radio resource usage in unlicensed frequency bands. More specifically, the present invention provides a set of spectrum etiquette rules for governing how a radio system operates in an unlicensed frequency band. Background technique [0002] National regulatory agencies coordinate the use of the radio spectrum and the regulation of radio emissions. As part of radio regulation, the radio spectrum is divided into frequency bands, and licenses to use the frequency bands are given to operators for a long period of time, such as ten or twenty years. Generally, different frequency bands are allocated to different types of radio services. Typical radio services include, for example, radionavigation and radiolocation, mobile communications and TV broadcasting. Operators who have granted licenses generally have exclusive rights to use the respective radio resources for providing r...
