    Abstract: En un sistema inalámbrico (100, 120) de comunicaciones, un procedimiento (700) de planificación, que comprende: recibir indicadores de la condición del canal de recepción de una pluralidad de usuarios móviles (106), en el que los indicadores de la condición del canal se corresponden con comunicaciones de enlace directo; determinar (702) una función (A) que se corresponde con cada uno de los indicadores de la condición del canal, dada como: **(Ver fórmula)** en la que Ai(t) es una función del indicador de la condición del canal para un usuario móvil iésimo, Bi(t) es el indicador de la condición del canal del usuario móvil iésimo en el instante t, B_MEDi(t) es un valor medio de los indicadores de la condición del canal recibidos recientemente del usuario móvil iésimo, y N es el número total de usuarios móviles en la pluralidad de usuarios móviles; determinar (706) un indicador de equidad para cada usuario móvil como una función del rendimiento a la pluralidad de usuarios móviles; y determinar (708, 710) una planificación de transmisión para la pluralidad de usuarios móviles, en el que la planificación de transmisión es una función de las funciones Ai(t) y de los indicadores de equidad.

    Abstract: Method and apparatus for a generalized scheduler for scheduling transmissions in a communications system. The scheduler is defined by a priority function of the channel condition and fairness criteria. The generalized scheduler is adapted to apply a variety of combinations of channel condition metrics and user fairness metrics. The scheduler distinguishes among classes of users, allowing individual processing per class. In one embodiment, a system controller receives a Delivery Priority Parameter (DPP) for each of a plurality of users, and maps each DPP to a corresponding common Mapped Priority Parameter (MPP). An operating point is determined and a corresponding MPP value for each of the users is applied to schedule transmissions.

    Abstract: A novel method is disclosed for the allocation of the capacity of a common channel among a number of data producers. In this method, a producer's future allocation grant is based on the extent to which the producer has used a previous allocation grant. The method is applicable to any system wherein the simultaneous use of a common channel by more than one producer may course a data collision, and an exemplary application to the reverse link of a CDMA telecommunications system is described. Also disclosed are numerous variations and refinements concerning the estimation of remaining channel capacity, the distribution of such capacity among the various producers, and the use of its allocation grant by each producers and the use of its allocation grant by each producer.

    Abstract: A method and apparatus for controlling a data rate associated with the transmission of information from a base station (100) to a mobile station (300) in a mobile radio communication system. The mobile station (300) alternately receives information from a basestation (100) either in a variable rate mode or a fixed rate mode. The transmission rate from a base station (600) in the variable rate mode varies between successive data transmit intervals, and the transmission rate from a base station in the fixed rate mode remains fixed between successive data transmit intervals. Data is transmitted from a first base station (400) to the mobile station in the variable rate mode until the first base station is unable to receive the variable data rate control information from the mobile station. When the first base station (400) is unable to receive the variable data rate control information from the mobile station (300), the mobile station (300) attempts to remain in the variable rate mode by searching for a second base station that will support data transmissions to the mobile station (300) in the variable rate mode and, if the mobile station (300) is able to locate the second base station that will support data transmissions to the mobile station in the variable rate mode, then the second base station transmits data to the mobile station in the variable rate mode and transmissions from the first base station to the mobile station (300) in the variable rate mode terminate. If the mobile station is unable to locate the second base station that will support data transmissions to the mobile station in the variable rate mode, data is transmitted to the mobile station (300) from either the first base station (400) or a different base station in the fixed rate mode.
