Method and apparatus for wireless communication on multiple spectrum bands
First Claim
1. A method, performed by a transmitter device, for simultaneously communicating on at least two carrier frequencies, of which at least one carrier frequency is a licensed band and at least one carrier frequency is an unlicensed band, the method comprising:
- broadcasting an operating status of the unlicensed band to a receiver device;
collecting feedback data regarding channel conditions from the receiver device for both the licensed band and unlicensed band;
determining, when a bandwidth request is received from the receiver device, whether to use the unlicensed band based on the channel conditions;
transmitting an unlicensed band scheduling indication to the receiver device; and
communicating with the receiver device using both the licensed band and the unlicensed band according to the transmitted unlicensed band scheduling indication.

Abstract
A method and apparatus for simultaneously communicating on at least two carrier frequencies, of which at least one carrier frequency is a licensed band and at least one carrier frequency is an unlicensed band are provided. The method includes broadcasting an operating status of the unlicensed band to a receiver device; collecting feedback data regarding channel conditions from the receiver device for both the licensed band and unlicensed band; determining, when a bandwidth request is received from the receiver device, whether to use the unlicensed band based on the channel conditions; transmitting an unlicensed band scheduling indication to the receiver device; and communicating with the receiver device using both the licensed band and the unlicensed band according to the transmitted unlicensed band scheduling indication.

5. A method, performed by a receiver device, for simultaneously communicating over at least two carrier frequencies, of which at least one carrier frequency is a licensed band and at least one carrier frequency is an unlicensed band, the method comprising of:
-
receiving an operating status of the unlicensed band from a transmitter device; transmitting feedback data regarding channel conditions to the transmitter device for both the licensed band and unlicensed band; transmitting a bandwidth request to the transmitter device; receiving an unlicensed band scheduling indication from the transmitter device; and communicating with the transmitter device using both the licensed band and the unlicensed band according to received the unlicensed band scheduling information. - View Dependent Claims (6, 7, 8)

9. A transmitter for simultaneously communicating on at least two carrier frequencies, of which at least one carrier frequency is a licensed band and at least one carrier frequency is an unlicensed band, the transmitter comprising:
-
a first radio frequency component for operating at the licensed band; a second radio frequency component for operating at the unlicensed band; and a controller for performing at least one of a first operation of broadcasting an operating status of the unlicensed band to a receiver and a second operation of collecting feedback data regarding channel conditions from the receiver for both the licensed band and unlicensed band, determining, when a bandwidth request is received from the receiver, whether to use the unlicensed band based on the channel conditions, transmitting an unlicensed band scheduling indication to the receiver, and communicating with the receiver using both the licensed band and the unlicensed band. - View Dependent Claims (10, 11, 12)
