Method and system for controlling power in a communication system

A method for controlling power by a receiver in a communication system, the method comprising:

• receiving, by the receiver, downlink (DL) data for a communication service though a Time Division Duplexing (TDD) DL region applied a TDD communication scheme, allocated from a transmitter, and measuring, by the receiver, a strength of the received data in a TDD uplink (UL) region applied the TDD communication scheme while receiving the DL data from the transmitter through the TDD DL region;
• generating, by the receiver, power control information according to the measured strength of the received data, and transmitting the generated power control information to the transmitter through a Frequency Division Duplexing (FDD) UL region applied an FDD communication scheme, allocated from the transmitter;
• and
• receiving, by the receiver, the DL data for the communication service through the TDD DL region with transmission power, a level of which is controlled according to the transmitted power control information;
• wherein measuring the strength of the received data comprises measuring a Signal-to-Interference and Noise Ratio (SINR) of the received data in the TDD DL region through which the DL data for the communication service is received.

A system for controlling power in a communication system, the system comprising:

• a transmitter for Channel State Information (CSI) between the transmitter and a receiver from the receiver through a Time Division Duplexing (TDD) uplink (UL) region, allocating TDD regions by applying a TDD communication scheme and a Frequency Division Duplexing (FDD) UL region by applying an FDD communication scheme, in accordance with the CSI, the TDD regions including the TDD UL region and a TDD downlink (DL) region, providing DL data for a communication service to a receiver through the TDD DL region, receiving power control information from the receiver through the FDD UL region while providing the DL data for the communication service, adjusting a level of transmission power used for providing the DL data for the communication service according to the received power control information, and providing the DL data for the communication service to the receiver using the adjusted transmission power;
• and
• the receiver for receiving the DL data for the communication service through the TDD DL region allocated from the transmitter, measuring strength of received data in the TDD DL region while receiving the DL data from the transmitter through the TDD DL region, generating power control information according to the measured strength of the received data, transmitting the generated power control information to the transmitter through the FDD UL region, and receiving the DL data for the communication service through the TDD DL region with transmission power, a level of which is controlled according to the transmitted power control information;
• wherein the receiver measures the strength of the received data by measuring a Signal-to-Interference and Noise Ratio (SINR) of the received data in the TDD DL region through which the DL data for the communication service is received.
