MOBILE COMMUNICATION SYSTEM AND A TRANSMITTING METHOD FOR DATA THEREOF CAPABLE OF TRANSMITTING ACK/NACK FEEDBACKS FOR UPLINK TRANSMISSION

摘要

PURPOSE: A mobile communication system and a transmitting method for data thereof are provided to retransmit uplink data in a dynamic subframe by controlling a transmission unit through a controller. CONSTITUTION: A base station sets subframes, which are not involved, as dynamic subframes(1101). The base station schedules the preset dynamic subframes with an UL grant(1102). The base station receives uplink data from a terminal through the scheduled dynamic subframes(1103). The base station determines whether uplink data decipher is succeeded or not(1104). The base station transmits an HARQ(hybrid automatic request) ACK/NACK or an UL grant for an uplink data re-transmission in the subframes(1105).
