Method and apparatus for wireless communication on multiple spectrum bands
First Claim
1. A first network node for serving a User Equipment (UE) with a second network node, the first network node comprising:
- a first layer for splitting a data stream delivered from an upper layer into a first data steam and a second data stream, for delivering the first data stream to a second layer of the first network node, and for delivering the second data stream to a second layer of the second network node;
the second layer of the first network node for generating a first Packet Data Unit (PDU) using the first data stream; and
a transmitter for transmitting the first PDU to the UE via a resource of the first network node.

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.
