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.
