Abstract: A mobile wireless telecommunications system includes base stations (30) of a first type operating according to a first air interface, and base stations (36) of a second type operating according to a second air interface. Methods and apparatus are provided for handing over a mobile station (40) in the system from a first base station (30), which is of the first type, to a second base station (36), which is of the second type. A communications link is established over the first air interface between the mobile station (40) and the first base station (30). Data is received from the mobile station (40) responsive to a signal received by the mobile station (40) over the second air interface from the second base station (36), substantially without breaking the communications link with the first base station. The mobile station (40) is handed over from the first (30) to the second base station (36) responsive to the data received therefrom.

Abstract: A system and method for a time-scalable priority-based scheduler. A flexible scheduling algorithm utilizing variable scheduling durations enables better system capacity utilization. A rate request (408) is transmitted if data arrives in a buffer, data in the buffer exceeds a buffer depth, and sufficient power exists to transmit at the rate requested. A rate assignment (418) responsive to the rate request indicates a scheduled duration and a scheduled rate applicable for the scheduled duration. The scheduled duration is less than or equal to a scheduling period (508). The scheduling period is an interval of time after which a scheduler makes a scheduling decision. The scheduling period is variable and the scheduled duration is variable. The scheduler is preferably applied in a UMTS, CDMA 2000 or HDR-system for reverse link rate scheduling.

Abstract: Un procedimiento, realizado en una estación base que funciona como una estación base no en servicio para al menos una estación móvil servida por otra estación base, para asignar recursos de enlace inverso a estaciones móviles servidas por la estación base en un sistema de comunicaciones de estaciones base distribuidas, comprendiendo el procedimiento: medir los parámetros de la carga acoplada de las transmisiones del enlace inverso de al menos una estación móvil servida por otra estación base; calcular una carga acoplada esperada estimada debida a transmisiones del enlace inverso de al menos una estación móvil en base a parámetros de la carga acoplada; asignar recursos del enlace inverso a otras estaciones móviles servidas por la estación base de acuerdo con la carga acoplada esperada estimada; en el que la asignación de recursos del enlace inverso comprende la programación de las tasas de transmisión de datos a otras estaciones móviles servidas por la estación base para crear una carga total del enlace inverso debida a las otras estaciones móviles en la estación base que no exceda la diferencia de la capacidad total de la estación base y la carga acoplada esperada estimada; en el que la estimación comprende calcular una carga acoplada anterior debida a las transmisiones del enlace inverso de al menos una estación móvil en base a los parámetros de carga acoplada medidos durante un periodo de transmisión anterior; y calcular la carga acoplada esperada estimada en base a la carga acoplada anterior; en el que, el cálculo de la carga acoplada esperada estimada comprende calcular la carga acoplada esperada estimada para que sea igual que la carga acoplada anterior; en el que, el cálculo de la carga acoplada anterior comprende calcular una pluralidad de cargas acopladas anteriores; y en el que el cálculo de la carga acoplada esperada estimada comprende además calcular una carga acoplada esperada total promediada de la pluralidad de cargas acopladas anteriores.

Abstract: A method and apparatus for controlling a data rate of a transmission in a wireless communication system during handoff. Controlling the data rate includes receiving transmissions from a plurality of base stations, wherein at least one of the received transmissions includes an acknowledgement message. Then determining a rate control command included within transmissions of the base station that includes the acknowledgement message and using the command to control the data rate. Controlling the data rate also includes receiving transmissions from a plurality of base stations. Then determining a plurality of rate control commands included within the received transmissions from the plurality of base stations. The rate control commands are then combined and used to control the data rate.

Abstract: Embodiments disclosed herein address the need in the art for reduced overhead control with the ability to adjust transmission rates as necessary. In one aspect, a first signal indicates an acknowledgement of a decoded subpacket and whether or not a rate control command is generated, and a second signal conditionally indicates the rate control command when one is generated. In another aspect, a grant may be generated concurrently with the acknowledgement. In yet another aspect, a mobile station monitors the first signal, conditionally monitors the second signal as indicated by the first signal, and may monitor a third signal comprising a grant. In yet another aspect, one or more base stations transmit one or more of the various signals. Various other aspects are also presented. These aspects have the benefit of providing the flexibility of grant-based control while utilizing lower overhead when rate control commands are used, thus increasing system utilization, increasing capacity and throughput.
