Method and apparatus for high rate data transmission in wireless communication

A procedure, comprising: receive (812) information for configuring multiple forward link carriers, FL, and at least one reverse link carrier, RL, wherein the multiple FL carriers and the at least one RL carrier are arranged in at least one group, each including group at least one FL carrier and a single RL carrier, and where at least one group includes at least two FL carriers, wherein one FL carrier and one RL carrier among the configured carriers are designated as FL main carrier and RL main carrier, respectively, wherein the FL main carrier has the purpose of one or more of originating a call, receiving signaling during call setup, perform a Layer 3 signaling handover procedure, select a serving base station for FL transmission based on the main FL carrier, send power control for a reverse pilot channel, R-PICH, send rate control for a reverse packet data channel, R-PDCH, send acknowledgments on a forward acknowledgment channel, F-ACKCH, for transmissions reverse link, sending MAC control messages on a forward packet data control channel, F-PDCCH, to a terminal, and sending forward grant messages on a forward grant channel, F-GCH, to a terminal; and after having received the information: receiving (814) a data transmission comprising packets on one or more of the multiple FL carriers previously configured in the group; receiving (822) a designated FL signaling on the main FL carrier; and sending (820) designated RL signaling on the main RL carrier.
