APPARATUS AND METHOD REALIZING A COGNITIVE ENABLER FOR UNLICENSED BAND COMMUNICATION USING LICENSED FEEDBACK IN MULTI-BAND RADIO CHANNELS

摘要

An apparatus for receiving data includes a data receiver for receiving the data, wherein the data is transmitted in a first channel by a first transmission. Moreover, the apparatus includes a transmit information transmitter for transmitting transmission information in a second channel by a second transmission. The transmission information is control information depending on the first transmission, or the transmission information is channel quality information indicating a channel quality of the first channel. The second channel is different from the first channel. Moreover, an apparatus for transmitting data and a system are provided.
