Abstract

Multiple full channel quality indication (CQI) reports indicative of received signal quality for multiple carriers in wireless communication are transmitted in multiple time intervals of a CQI channel.

Claims

1. A method for communications, comprising:

receiving multiple packets over multiple downlink carriers;

generating multiple acknowledgements associated with the received multiple packets;

generating a plurality of modulation symbols from the multiple acknowledgements;

transmitting a single physical channel acknowledgement message via a control channel of an uplink carrier, the single physical channel acknowledgement message comprising the plurality of modulation symbols.

2. The method of claim 1, wherein the generating the plurality of modulation symbols comprises:

spreading the multiple acknowledgements to obtain the plurality of modulation symbols.

3. The method of claim 1, wherein the plurality of modulation symbols correspond to a predetermined number of modulation symbols irrespective of a number of the multiple downlink carriers.

4. The method of claim 1, wherein the generating the plurality of modulation symbols comprises:

mapping each of the acknowledgements to a mapped signal point value; and

covering each of the mapped signal point values with an orthogonal cover code of a plurality of orthogonal cover codes to obtain a symbol sequence.

5. The method of claim 4, wherein the generating the plurality of modulation symbols comprises:

repeating each of the symbol sequences to obtain a repeated symbol sequence.

6. The method of claim 5, wherein the generating the plurality of modulation symbols comprises:
