A method of transmission acknowledge/not acknowledge (ACK/NAK) with repetition in a user equipment comprising the steps of: determining if a Physical Downlink Shared CHannel (PDSCH) transmission directed to a particular user equipment is received in a subframe without receiving a PDSCH transmission directed to the particular user equipment in a next following subframe; transmitting an ACK/NAK response to the PDSCH transmission in a second subframe a predetermined number of subframes following the PDSCH transmission and in a repeat number of immediately following subframes; determining if a PDSCH transmission directed to the particular user equipment is received in two consecutive subframes; transmitting a first ACK/NAK response to a first of the PDSCH transmissions of the first of the two consecutive subframes in a fourth subframe the predetermined number of subframes following the first PDSCH transmission received in a first of the two consecutive subframes; and transmitting a second ACK/NAK response to a second of the PDSCH transmissions of the second of the two consecutive subframes in a fifth subframe immediately following the fourth subframe and not transmitting a repeat of the first ACK/NAK response in the fifth subframe.
