    Abstract: A method of and apparatus for scheduling data transmissions in a communication network comprising at least one cell (2a to 2g) and at least one scheduled user (6a to 6e) improves utilization of the reverse link and decreases the transmission delay in data communication. The apparatus comprises a controller (92) for collecting status information for said communication network and for scheduling data transmissions from said at least one cell (2a to 2g) to said at least one scheduled user (6a to 6e). A memory (94) is connected to said controller for storing said status information, and a timer (96) is connected to provide timing signals to said controller (92). The timing signals enable said controller to perform scheduling of data transmission. Each remote station is assigned a maximum unscheduled transmission rate for the duration of the communication with a cell. A maximum scheduled transmission rate can be assigned by a channel scheduler (12) for scheduled transmission of data traffic at high rates. The maximum scheduled transmission rate is assigned in accordance with a set of system goals, a list of system constraints, and collected information on the status of the communication network. Data is partitioned in data frames and transmitted over the reverse link at or below the maximum scheduled transmission rate which have been assigned to the scheduled user.

    Abstract: 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.

    Abstract: In a communication system capable of variable rate transmission, multi-level scheduling improves utilization of the reverse link and decreases the transmission delay in data communication. Multi-level scheduling comprises base station level scheduling, selector level (system level) scheduling, and network level scheduling. Network level scheduling is performed for base station in soft handoff with base stations which are controlled by different selector scheduler. Selector level scheduling is performed for remote stations in soft handoff with base stations which are controlled by the same selector scheduler. And base station level scheduling is performed for remote stations not in soft handoff. Base station level scheduled is performed using residual capacity after higher level scheduling have been performed. Each scheduling level can have different scheduling interval.
