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.

A user equipment operable in a wireless communication with a base station method, the user equipment operable to:
- receive a Physical Downlink Shared CHannel (PDSCH) transmission directed to said user equipment by a base station;
- if a PDSCH transmission directed to said user equipment is received in a subframe without receiving a PDSCH transmission directed to said user equipment in a next following subframe, transmit 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;
- if a PDSCH transmission directed to said user equipment is received in two consecutive subframes
- transmit a first ACK/NAK response to a first of the PDSCH transmissions of the two consecutive subframes in a fourth subframe the predetermined number of subframes following the first PDSCH transmission received in a first the consecutive subframes, and
- transmit a second ACK/NAK response to a second of the PDSCH transmissions 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.
A user equipment operable in a wireless communication with a base station method, the user equipment operable to:
- receive a Physical Downlink Shared CHannel (PDSCH) transmission directed to said user equipment by a base station;
- if a PDSCH transmission directed to said user equipment is received in a subframe without receiving a PDSCH transmission directed to said user equipment in a next following subframe, transmit 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;
- if a PDSCH transmission directed to a particular user equipment is received in two consecutive subframes
- transmit a first ACK/NAK response to a first of the PDSCH transmissions of the two consecutive subframes in a fourth subframe the predetermined number of subframes following the first PDSCH transmission, and
- transmit a repeat of the first ACK/NAK response to the first of the PDSCH transmissions of the two consecutive subframes in a fifth subframe immediately following the fourth subframe and not transmitting a second ACK/NAK response to the second of the PDSCH transmissions of the two consecutive subframes in the fifth subframe.
