Abstract
A method and apparatus for reliably and quickly establishing multiple reverse links in multi-carrier wireless networks is provided. Signaling channels are established on an existing forward link in order to transmit reverse link power control bits and the acknowledgment indications.
Claims8
A method of receiving control information at a mobile station (MS) in a multi-carrier wireless communication system, the method comprising:
- establishing multiple forward link carriers between the MS and a base station (BS), wherein each of the multiple forward link carriers is separated from each other in a frequency domain;
- establishing multiple reverse link carriers between the MS and the BS, wherein each of the multiple reverse link carriers is associated with a respective one of the multiple forward link carriers, and separated from each other in the frequency domain;
- receiving a first acknowledgement (ACK) signal for a first data transmitted via a first reverse link carrier of the multiple reverse link carriers;
- receiving a second ACK signal for a second data transmitted via a second reverse link carrier of the multiple reverse link carriers;
- transmitting first channel quality information for a first forward link carrier of the multiple forward link carriers;
- and
- transmitting second channel quality information for a second forward link carrier the multiple forward link carriers;
- wherein the first ACK signal for the first data and the second ACK signal for the second data are received from the BS via a common forward link carrier of the multiple forward link carriers between the MS and the BS, and
- wherein the first channel quality information for the first forward link carrier and the second channel quality information for the second forward link carrier are transmitted to the BS via a common reverse link carrier of the multiple reverse link carriers between the MS and the BS.
