    摘要： 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.

    摘要： A method of accessing a system utilizing multiple data rates. The method includes determining a desired transmission data rate and setting a current data transmission rate to the desired transmission data rate if the desired rate is less than a maximum transmission rate. The current data transmission rate is set to the maximum transmission rate with a probability equal to a transmission probability if the desired transmission rate exceeds or is equal to the maximum transmission rate. Also described is a multiple access communication system including a base station which uses an indication of system loading to determine a transmission probability and a maximum transmission rate for the system and broadcasts the transmission probability and the maximum transmission rate to a plurality of remote units. A remote unit transmits data to the base station at the maximum transmission rate with the transmission probability. A multiple access communication system may include a receiver for receiving a maximum transmission rate and a transmission probability produced by a base unit, a process for determining a desired transmission data rate, a process for setting a current data transmission rate equal to the desired transmission data rate if the desired rate is less than a maximum transmission rate, and a process for setting the current data transmission rate to the maximum transmission rate with a probability equal to the transmission probability if the desired transmission rate exceeds or is equal to the maximum transmission rate. A transmitter transmits data to the base unit at the current data transmission rate.

    摘要： A mobile station may include a standard transmit pulse-shaping filter, a standard receive pulse-shaping filter, a narrower transmit pulse-shaping filter, and a narrower receive pulse-shaping filter. A femtocell base station may include a narrower transmit pulse-shaping filter and a narrower receive pulse-shaping filter. The mobile station may utilize the narrower transmit pulse-shaping filter for transmitting uplink signals and the narrower receive pulse-shaping filter for receiving downlink signals when it is receiving service from the femtocell base station. The mobile station may utilize the standard transmit pulse-shaping filter for transmitting uplink signals and the standard receive pulse-shaping filter for receiving downlink signals when it is receiving service from a macrocell base station.

    摘要： 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.
