Apparatus and method for controlling a hybrid automatic repeat request operation in a wireless mobile communication system

A method for controlling a Hybrid Automatic Repeat reQuest (HARQ) operation in a receiver of a wireless mobile communication system using each frame constituted by a plurality of subframes, the method comprising:

• receiving indication information, indicating a subframe position where transmission of a data burst starts and the number of subframes required for transmission of the data burst, from a transmitter through an i-th frame;
• determining to receive the data burst retransmitted at the subframe position indicated by indication information of an (i+1)-th frame from the transmitter when the number of subframes does not exceed a threshold;
• and
• determining to receive the data burst retransmitted at the subframe position indicated by indication information of an (i+n)-th frame from the transmitter, where n is a positive integer exceeding 1, when the number of subframes exceeds the threshold.

A receiver for controlling a Hybrid Automatic Repeat reQuest (HARQ) operation in a wireless mobile communication system using each frame constituted by a plurality of subframes, the receiver comprising:

• a data burst transmission information reader for reading indication information indicating a subframe position where transmission of a data burst starts and the number of subframes required for transmission of the data burst from a transmitter through an i-th frame and for outputting a read result;
• a comparator for comparing the number of subframes with a threshold and for outputting a comparison result;
• and
• a controller for determining to receive the data burst retransmitted at the subframe position indicated by indication information of an (i+1)-th frame from the transmitter when the number of subframes does not exceed the threshold, and for determining to receive the data burst retransmitted at the subframe position indicated by indication information of an (i+n)-th frame from the transmitter, where n is a positive integer exceeding 1, when the number of subframes exceeds the threshold.
