Carrier Aggregation Using Unlicensed Frequency Bands
First Claim
1. A wireless user equipment (UE) device, comprising:
- a radio, comprising one or more antennas configured for wireless communication; and
a processing element operably coupled to the radio,wherein the radio and the processing element are configured to;
establish a primary carrier with a base station according to a cellular communication technology, wherein the primary carrier is on a licensed frequency band;
establish a secondary carrier with the base station according to the cellular communication technology, wherein the secondary carrier is on an unlicensed frequency band.

Abstract
Carrier aggregation using unlicensed frequency bands. A primary carrier for communication between a base station (BS) and a wireless user equipment (UE) device may be configured according to a first wireless communication technology. The primary carrier may be on a licensed frequency band. A secondary carrier for communication between the BS and the UE may also be configured according to a first wireless communication technology. The secondary carrier may be on an unlicensed frequency band. Channel conditions for each of multiple possible channels of the unlicensed frequency band may be assessed according to a second wireless communication technology as part of configuring the secondary carrier.
