Abstract
A radio base station transmits data symbols to a mobile terminal on multiple frequency carriers, e.g., in accordance with the MC-WCDMA or cdma2000 3× air interface protocols. The radio base station instructs the mobile terminal to report channel quality measurements obtained by the terminal for the multiple carriers over the same uplink channel during successive reporting intervals. According to one embodiment, the mobile terminal reports channel quality by receiving data symbols transmitted on a plurality of frequency carriers in a multi-carrier CDMA environment and measuring channel quality for the different frequency carriers. The mobile terminal reports individual ones of the channel quality measurements over the same uplink channel during successive reporting intervals.
