Method and apparatus for wireless communication on multiple spectrum bands
First Claim
1. A method of a user equipment (UE) for communication, the method comprising:
- receiving information for activating a second frequency on a first frequency;
receiving first control information for a first resource allocation on the first frequency;
receiving second control information for a second resource allocation on the second frequency;
receiving first data on the first frequency;
receiving second data on the second frequency;
generating packet data units (PDUs) for the first data at a second layer corresponding to the first frequency, and generating PDUs for the second data at a second layer corresponding to the second frequency; and
receiving, at a first layer associated with the first frequency and the second frequency, the PDUs for the first data and the PDUs for the second data.

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, 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.
