US 2014/0351379 A1 · COGNITIVE USE OF MULTIPLE REGULATORY DOMAINS

Abstract

A wireless communication system that concurrently communicates information in multiple regulatory domains to facilitate audio/video media streaming and other high bandwidth operations. One domain may be licensed and the other may be unlicensed. Transmission in the licensed domain may occur in white space in the domain, and the amount of information transmitted in that domain may be limited by regulations. The amount of information conveyed in the licensed domain may also depend on channel conditions in either or both of the domains. As a result, the relative amount of information transmitted in each domain may vary dynamically. The system includes a transmitter that dynamically determines weighting coefficients applied to each of a plurality of channels to set power levels in both domains to achieve a desired metric for the overall communication. A corresponding receiver assembles the substreams into a stream that can then be displayed or otherwise processed.

Dependent claims

A method of operating a wireless computing device having at least one radio, the method comprising:

dynamically determining at least one frequency in a first regulatory domain and at least one frequency in a second regulatory domain;
decomposing data for transmission into at least a first portion and a second portion;
and
with the at least one radio, concurrently transmitting at least the first portion using the at least one frequency in the first regulatory domain and the second portion using the at least one frequency in the second regulatory domain.

1 more element

A wireless computing device, comprising:

an application providing a stream representing audio/video content;
a radio subsystem configured for communicating in a first wireless domain and a second wireless domain, the first wireless domain being an unlicensed domain and the second wireless domain being a licensed domain;
a network adapter configured to accept the stream for transmission by applying the stream to the radio subsystem for transmission in the first wireless domain and the second wireless domain, the network adapter comprising:
a multiplexer to separate the stream into a first sub-stream and a second sub-stream;
a modulation component to generate coefficients from the first substream and the second substream, the coefficients being coefficients for transmission of frequency components in the first domain and the second domain to transmit the first substream and the second substream;
and
a weighting component to dynamically determine at least one weight based on regulatory conditions applicable to the second domain and to apply the at least one weight to the coefficients of the first substream and/or the second substream.
