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 wireless computing device, comprising:

at least one radio,
at least one memory;
and
at least one processor, wherein the at least one memory and the at least one processor are respectively configured to store and execute a policy engine component that is configured to:
dynamically determine at least one frequency in a first regulatory domain and at least one frequency in a second regulatory domain;
determine a transmit power level for each of the at least one frequencies in the second regulatory domain, wherein the transmit power level is determined at least in part based on regulatory constraints within the second regulatory domain;
cause data for transmission to be decomposed into at least a first portion and a second portion;
and
cause the at least one radio, to concurrently transmit 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.

6 more elements

A wireless computing device, comprising:

a radio subsystem,
at least one memory;
and
at least one processor, wherein the at least one memory and the at least one processor are respectively configured to store and execute instructions that cause the wireless computing device to:
receive data via the radio subsystem, the reception of data including:
reception of a first portion of the data over at least one frequency in a first regulatory domain;
reception of a second portion of the data over at least one frequency in a second regulatory domain;
and
generation of output data by combining the first portion with the second portion;
and
adapt to a change in the at least one frequency in the second regulatory domain, wherein:
reception of the second portion of the data over the at least one frequency in the second regulatory domain comprises reception of the second portion over a first set of subchannels in the second regulatory domain;
and
adaptation to the change in the at least one frequency comprises subsequently receiving a third portion of the data over a second set of subchannels different than the first set of subchannels.
