COMMUNICATION SYSTEM, BASE STATION APPARATUS, TERMINAL APPARATUS, AND COMMUNICATION METHOD |
| 摘要 |
The present invention is designed to provide a communication system, a base station apparatus, a terminal apparatus and a communication method that can support the diversification of communication. In the communication system of the present invention, in which a terminal apparatus receives a downlink data signal transmitted from a base station apparatus (eNB) in a radio resource region for a downlink data signal, the base station apparatus transmits a terminal-specific reference signal in the radio resource region for the downlink data signal to the terminal apparatus (UE), and the terminal apparatus measures channel quality information based on the terminal-specific reference signal and transmits the measured channel quality information to the base station apparatus. |
