Apparatus and method for performing communication using frame structure supporting H-FDD operation

A method for performing a half-frequency division duplex (H-FDD) operation at a base station (BS) in a mobile communication system using a frequency division duplex (FDD) frame structure supporting the H-FDD operation, the method comprising:

• transmitting a superframe header (SFH) or a preamble to a H-FDD mobile station (H-FDD MS) through a first downlink subframe;
• and
• scheduling at least one subframe, except for a first uplink subframe, a second uplink subframe and a last uplink subframe of a FDD frame,
• wherein the first uplink subframe, the second uplink subframe and the last uplink subframe of the FDD frame are configured as idle subframes for the H-FDD MS,
• wherein the first uplink subframe is located at a beginning of the FDD frame and is immediately followed by the second uplink subframe in the FDD frame, and
• wherein the first uplink subframe is aligned with the first downlink subframe in a time domain of the FDD frame.

A half-frequency division duplex mobile station (H-FDD MS) for performing a HDD operation using a frequency division duplex (FDD) frame structure that supports the H-FDD operation in a mobile communication system, the H-FDD MS comprising:

• a receiver;
• a transmitter;
• and
• a processor,
• wherein the processor is configured to control the receiver to receive a superframe header (SFH) or a preamble from a base station (BS) through a first downlink subframe and the transmitter to transmit a signal through at least one uplink subframe, except for a first uplink subframe, a second uplink subframe and a last uplink subframe of a FDD frame,
• wherein the first uplink subframe, the second uplink subframe and the last uplink subframe of the FDD frame are configured as idle subframes for the H-FDD MS,
• wherein the first uplink subframe is located at a beginning of the FDD frame and is immediately followed by the second uplink subframe in the FDD frame, and
• wherein the first uplink subframe is aligned with the first downlink subframe in a time domain of the FDD frame.

A base station (BS) for transmitting resource allocation information in a mobile communication system using a frequency division duplex (FDD) frame structure supporting a half-frequency division duplex (H-FDD) operation, the BS comprising:

• a transmitter;
• and
• a processor,
• wherein the processor is configured to control the transmitter to transmit a superframe header (SFH) or a preamble to a H-FDD mobile station (H-FDD MS) through a first downlink subframe and schedule at least one subframe, except for a first uplink subframe, a second uplink subframe and a last uplink subframe of a FDD frame,
• wherein the first uplink subframe, the second uplink subframe and the last uplink subframe of the FDD frame are configured as idle subframes for the H-FDD MS,
• wherein the first uplink subframe is located at a beginning of the FDD frame and the first uplink subframe is immediately followed by the second uplink subframe in the FDD frame, and
• wherein the first uplink subframe is aligned with the first downlink subframe in a time domain of the FDD frame.
