Abstract
In ACK/NAK responses with repetition the ACK/NAK response from the user equipment to a Physical Downlink Shared CHannel (PDSCH) transmission is repeated in consecutive frames a predetermined number of frames following receipt. This repeat ACK/NAK causes a problem when a PSCCH transmission directed to the same user equipment occurs in consecutive subframes. In a first embodiment the first ACK/NAK response repeats preempting any ACK/NAK response to the later PDSCH transmission. In a second embodiment the first ACK/NAK response does not repeat and the ACK/NAK response to the later PDSCH transmission occurs.
