Abstract: A scheduler and a method for scheduling transmissions to a plurality of users (105) in a communication network assigns a higher target minimum throughput for receiving a next transmission to a user based on a quality of service (QoS) class of the user. A token count that tracks the user's achieved performance relative to a target minimum throughput Is determined for each user in given timeslot, and a weight is determined for each user based on one or more of the token count and a current rate requested by the user. A user having the highest weight as determined by a weight function is scheduled to be served the next transmission. User priority for scheduling may be downgraded if an average data rate requested by the user is less than the target minimum throughput.

Abstract: Un método para transmitir datos que comprende los pasos de: codificar mediante codificación de canal un paquete codificador para producir una paquete codificador codificado mediante codificación de canal; eliminar de manera selectiva y/o repetir el paquete codificador codificado mediante codificación de canal para producir un primer sub-paquete codificador (215) que tiene un primer tamaño basado en el tamaño del paquete codificador y una primera velocidad de transmisión de datos a la cual el primer sub-paquete codificador va a ser transmitido, donde la primera velocidad de transmisión de datos (210) es mayor que y está basada en una velocidad de transmisión de datos para transmitir el primer sub-paquete codificador, y la velocidad de transmisión de datos para transmitir el primer sub-paquete codificador es indicada en un primer mensaje de indicación de la velocidad (110) desde un receptor; transmitir el primer sub-paquete codificador a la primera velocidad de transmisión de datos; recibir un mensaje NACK (125) indicando que una transmisión del sub-paquete codificador no fue recibida exitosamente en un receptor al cual el primer sub-paquete codificador estaba dirigido; y eliminar de manera selectiva y/o repetir el paquete codificador codificado mediante codificación de canal, en respuesta al mensaje NACK (125) para producir un segundo sub-paquete codificador (215) que tiene un segundo tamaño basado en el tamaño del paquete codificador y una segunda velocidad de transmisión de datos a la cual el segundo sub-paquete codificador va a ser transmitido, el segundo tamaño siendo diferente del primer tamaño y la segunda velocidad de transmisión de datos siendo diferente de la primera velocidad de transmisión de datos.

Abstract: The error detection method includes decoding a portion of each control channel that is simultaneously received by a user equipment (UE) in a wireless communication system. The UE is provided with techniques to determine if one or more of the control channels were successfully received during the decoding step. If more than one control channel was successfully received, the method selects only one of the successfully received control channels based on calculated path metric differences (PMD) that serve as a "tie-breaking" mechanism to select the correct control channel for a particular UE.

Abstract: Disclosed is a method of sub-packet adaptation based on data rate. Specifically, the size of a sub-packet is adapted to a data rate at which the sub-packet is to be transmitted. In one embodiment, the sub-packet is size adapted to the data rate in a format that would allow such size adapted sub-packet to be soft combined with another sub-packet of a same or different size. The size adapted sub-packet may be transmitted prior to or after the other sub-packet.

Abstract: A method for scheduling transmissions to a plurality of users in a communication network determines a satisfaction metric and a dissatisfaction metric for each user in a given timeslot that is to be used for a next scheduled transmission to one of the users. Each user is assigned a weight based on a value of at least one of the user's satisfaction metric, the user's dissatisfaction metric and a rate requested by the user. The use having the highest weight is selected to be served the next scheduled transmission in the given timeslot.

Abstract: In an embodiment, a composite signaling message part is formed to include at least two segments (500), each segment (500) including data identifying a different user equipment (UE). In another embodiment, a different portion of a composite signaling message part is transmitted over at least one same time slot in each of the shared control channels; the part including at least two segments (510, 530) and each segment (510, 530) including data identifying a different user equipment (UE). In these embodiments, the part further includes a cyclic redundancy code (550), (CRC) generated by jointly encoding the at least two segments (510, 530). In a further aspect of the method, more than one shared control channel jointly carrying a signaling message are power controlled such that each shared control channel carrying more data associated with one of the UEs is power controlled in accordance with that UE. In a still further embodiment, the channelized code information for a dedicated control channel is divided between first and second parts of the shared control signals.
