Patent ID: 8331215

Claim:
A method of responding in a wireless user equipment (UE) with an acknowledge (ACK) or non-acknowledge (NAK) to a downlink (DL) communication from a base station using frames where at least one uplink (UL) is assigned a subframe to respond to a plurality of DL assigned subframes, comprising the steps of: generating an ACK response at the UE to each DL communication correctly received; generating a NAK response at the UE to each DL communication not correctly received; for a UL subframe assigned to respond to communications on plural DL subframes logically combining plural ACK/NAK responses into a first response state if any of said ACK/NAK responses is a NAK and a corresponding one of a plurality of second response states if all said plural ACK/NAK responses are ACKs; and transmitting ACK/NAK responses from the UE to the base station in an uplink communication including transmitting a first ACK/NAK signal if said logically combined plural ACK/NAK responses have said first response state and transmitting a corresponding one of a plurality of second ACK/NAK signals if said logically combined plural ACK/NAK responses have one of said second response states.
