Concurrent transmission of multiple acknowledge/not acknowledge and scheduling request indicator in time division duplex uplink signaling

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;

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.

2. The method of claim 1 , wherein:

said number of said plurality of DL assigned subframes is 2;

said uplink communication includes a scheduling request indicator (SRI);

said method further includes

if SRI is negative separately transmitting said plural ACK/NAK responses;

if SRI is positive said step of transmitting said first ACK/NAK signal transmits a first predetermined quadrature phase shift keying (QPSK) signal; and

if SRI is positive said step of transmitting said corresponding one of said plurality of second ACK/NAK signals transmits a corresponding second predetermined QPSK signal.

3. The method of claim 2 , wherein:

said corresponding second predetermined second QPSK signal is −a on the real axis if the bundled ACK/NAK bits represent ACK of the DL of a first subframe; and

said corresponding second predetermined second QPSK signal is +a on the imaginary axis if the bundled ACK/NAK bits represent ACK of the DL of a second subframe.

4. The method of claim 1 , wherein:

said number of said plurality of DL assigned subframes is 3;

said uplink communication includes a scheduling request indicator (SRI);

said method further includes

if SRI is negative separately transmitting said plural ACK/NAK responses;

if SRI is positive said step of transmitting said first ACK/NAK signal transmits a first predetermined quadrature phase shift keying (QPSK) signal; and

if SRI is positive said step of transmitting said corresponding one of said plurality of second ACK/NAK signals transmits a corresponding second predetermined QPSK signal.

5. The method of claim 4 , wherein:

said corresponding second predetermined second QPSK signal is −a on the real axis if the bundled ACK/NAK bits represent ACK of the DL of a first subframe;

said corresponding second predetermined second QPSK signal is +a on the imaginary axis if the bundled ACK/NAK bits represent ACK of the DL of a second subframe; and

said corresponding second predetermined second QPSK signal is −a on the imaginary axis if the bundled ACK/NAK bits represent ACK of the DL of a third subframe.

6. The method of claim 1 , wherein:

said number of said plurality of DL assigned subframes is 4;

said uplink communication includes a scheduling request indicator (SRI);

said method further includes

if SRI is negative separately transmitting said plural ACK/NAK responses;

if SRI is positive said step of transmitting said first ACK/NAK signal transmits a first predetermined quadrature phase shift keying (QPSK) signal; and

if SRI is positive said step of transmitting said corresponding one of said plurality of second ACK/NAK signals transmits a corresponding second predetermined QPSK signal.

7. The method of claim 6 , wherein:

said corresponding second predetermined second QPSK signal is −a on the real axis if the bundled ACK/NAK bits represent ACK of the DL of a first subframe or ACK of the DL of a fourth subframe;

said corresponding second predetermined second QPSK signal is +a on the imaginary axis if the bundled ACK/NAK bits represent ACK of the DL of a second subframe; and

said corresponding second predetermined second QPSK signal is −a on the imaginary axis if the bundled ACK/NAK bits represent ACK of the DL of a third subframe.

8. The method of claim 1 , wherein:

said number of said plurality of DL assigned subframes is 9;

said uplink communication includes a scheduling request indicator (SRI);

said method further includes

if SRI is negative separately transmitting said plural ACK/NAK responses;

if SRI is positive said step of transmitting said first ACK/NAK signal transmits a first predetermined quadrature phase shift keying (QPSK) signal; and

if SRI is positive said step of transmitting said corresponding one of said plurality of second ACK/NAK signals transmits a corresponding second predetermined QPSK signal.

9. The method of claim 8 , wherein:

said corresponding second predetermined second QPSK signal is −a on the real axis if the bundled ACK/NAK bits represent ACK of the DL of a first subframe, ACK of the DL of a fourth subframe or ACK of the DL of a seventh subframe;

said corresponding second predetermined second QPSK signal is +a on the imaginary axis if the bundled ACK/NAK bits represent ACK of the DL of a second subframe, ACK of the DL of a fifth subframe or ACK of the DL of an eighth subframe; and

said corresponding second predetermined second QPSK signal is −a on the imaginary axis if the bundled ACK/NAK bits represent ACK of the DL of a third subframe, ACK of the DL of a sixth subframe or ACK of a DL of a ninth subframe.
