• transmitting ACK/NAK responses from the UE to the base station including transmitting a bundled response.

A method of responding in a wireless user equipment (UE) with an acknowledge (ACK) or non-acknowledge (NAK) to a downlink (DL) communications 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;
• generating a discontinuous transmission (DTX) signal at the UE when the UE misses a DL grant in a corresponding DL subframe;
• for a UL subframe assigned to respond to communications on plural DL subframes logically combining plural ACK/NAK responses into a single bundled response including any relevant DTX signals, wherein said step of logically combining plural ACK/NAK responses is performed per codeword across M multiple DL subframes associated with a single UL subframe n, where M is the number of elements in the set K defined as:
