Abstract:
1. 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; generating a discontinuous transmittion (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: the DL communications are transmitted in a single input, multiple output (SIMO) transmission mode; a single UL subframe is assigned to respond to communications from 9 DL subframes; said step of logically combining logically combines ACK/NAK responses to DL communications in a first five subframes into a first bit and logically combines ACK/NAK responses to DL communications in a next four subframes into a second bit; and tranmitting ACK/NAK responses from the UE to the base station including transmitting a bundle response.
