Abstract: Un procedimiento para controlar la energía de transmisión de una pluralidad de canales de control compartidos que transportan conjuntamente un mensaje de señalización, incluyendo el mensaje de señalización datos para una pluralidad de equipos de usuario (UE), caracterizado por: asignar una porción del mensaje de señalización a cada uno de la pluralidad de canales de control compartidos, de modo que cada canal de control compartido transporte más datos adicionales asociados con uno en particular de la pluralidad de UE en comparación con los datos del resto de UE; y controlar la energía de transmisión para cada canal de control compartido basado en los datos adicionales del UE concreto asociado.

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.

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: Un método para determinar una tasa de datos para un canal de comunicaciones de enlace descendente compartido por una pluralidad de unidades inalámbricas (AT) para comunicación con una estación base (BS), en el que se adapta dicha tasa de datos (R1-R3 en 22a-q) basándose en información de realimentación (R1-R3 en 20a- e) de al menos una de las unidades inalámbricas (AT), caracterizándose dicho método por: recibir, a una tasa de realimentación, información de realimentación (R1-R3 en 20a-e) de al menos una unidad inalámbrica dada para calcular la tasa de datos (R1-R3 en 22a-q); y adaptar, a una tasa de adaptación diferente de la tasa de realimentación, dicha tasa de datos basándose en dicha información de realimentación, para que al menos la unidad inalámbrica dada la use en dicho canal de comunicaciones de enlace descendente.

Abstract: A transport channel multiplexing system provides improved use of wireless resources in a shared data channel system. For example, the transport channel system reduces the amount of transport format information required for using a shared data channel, such as the actual number of packet data units in a transport channel of the shared data channel. Additionally, by scheduling or multiplexing coded sub-blocks from one or more transport channels over the shared data channel, the transport channel multiplexing system can provide improved integration with other important features, such as incremental redundancy, fast adaptation to channel conditions and transport channel dependent quality of service (QOS) control, to provide improved system performance.
