In a communication system capable of variable rate transmission, scheduling of high speed data transmission improves utilization of the forward link and decreases the transmission delay in data communication. Each remote station is assigned one primary code channel for the duration of the communication with a cell. Secondary code channels of various types and transmission capabilities can be assigned by a channel scheduler for scheduled transmission of data traffic at high rates. Secondary code channels are assigned in accordance with a set of system goals, a list of parameters, and collected information on the status of the communication network. Secondary code channels can be grouped into sets of secondary code channels. Data is partitioned in data frames and transmitted over the primary and secondary code channels which have been assigned to the scheduled user.

1. A method for scheduling data transmissions on a forward link in a communication network comprising at least one cell and at least one scheduled user, and for assigning a transmission rate to said data transmissions, said forward link having an unscheduled capacity for unscheduled transmissions and a residual capacity for scheduled transmissions, the method comprising the steps of:determining said residual forward link capacity available for each of said at least one cell; assigning an assigned transmission rate to each of said at least one scheduled user; sending said assigned transmission rate to said at least one scheduled user; wherein said assigned transmission rate is based on said residual forward link capacity available for each of said at least one cell; wherein said assigning step further comprises the step of determining an active member set for each of said at least one scheduled user, said active member set containing at least one cell in communication with said scheduled user; wherein said assigned transmission rate is further based on said forward link capacity available for one or more of said at least one cell in said active member set.
