Abstract: Multi-user detection (MUD) performance is optimized to eliminate redundant use of power during processing. An overbuilt A-matrix, i.e., a system response matrix, is provided. The overbuilt A-matrix uses all possible codes, e.g., all codes identified in a candidate code list (CCL) provided by blind code detection (BCD). The overbuilt A-matrix is passed to the MUD which extracts only those rows or columns required for codes that have actually been received, thus eliminating the need to recompute whitening matched filter (WMF) outputs that do not correspond to the actually received code.

Abstract: A system and method that achieve power savings by turning off all or some of the baseband processing for codes and timeslots that have not been transmitted due to full DTX. When full DTX is detected by reception of a Special Burst (SB), the receiver is turned off for all timeslots and frames for the duration of the Special Burst Scheduling Period (SBSP). The transmitter schedules transmissions following any idle period to start on the boundary of the SBSP. The receiver determines the SBSP and if the transmitter initiates transmissions according to SBSP by reception of several initial full DTX cycles.

Abstract: The present invention discloses a method and system for enabling efficient reduction of TFCs in the TFCS to achieve desired transmission, while remaini ng within desired power and data requirements. Upon the UE transmission power requirement exceeding the maximum or allowable transmission power the MAC shall be informed for subsequent TFC selection of all TFCs that currently exceed .this limit. The UE will then chose the TFC with the next lower transmission power requirement and the sequence will continue until an acceptable TFC is determined. The present invention also enables the replacement of the TFCs in the TFCS and advanced determination of non- supported TFCs. The TFCs that require transmission power greater then the maximum or allowed UE transmission power shall be determined continuously in every TTI, not just in TTIs where the maximum power has been exceeded.

Abstract: METHOD AND APPARATUS FOR MULTICASTING WITH FEEDBACK INFORMATION 5 A METHOD FOR MULTICASTING A PACKET BEGINS BY PROVIDING A BUFFER FOR EACH OF TWO USER EQUIPMENTS (UES) IN COMMUNICATION WITH A BASE STATION. A DETERMINATION IS MADE WHETHER THERE IS A PREVIOUSLY UNSENT PACKET AT THE BASE STATION. A SECOND DETERMINATION IS MADE WHETHER BOTH UE BUFFERS ARE NON-EMPTY. A NON-EMPTY BUFFER IS FLUSHED IF THERE IS NO 1 0 PREVIOUSLY UNSENT PACKET AND IF ONE OF THE BUFFERS IS NON-EMPTY. A PACKET IS SELECTED TO BE TRANSMITTED IF THERE IS A PREVIOUSLY UNSENT PACKET OR IF BOTH BUFFERS ARE NON-EMPTY. THE BUFFERS ARE UPDATED BASED ON FEEDBACK RECEIVED FROM THE UES.

Abstract: Un método para seleccionar una combinacion de formato de transporte (TFC) en una comunicacion inalámbrica, método que comprende: establecer una lista de TFCs disponibles, en donde las TFCs disponible son clasificadas de acuerdo con un nivel de potencia de transmision requerido para transmitir cada TFC disponible; seleccionar una TFC a partir de una lista de TFCs disponibles; determinar si una potencia de transmision requerida para transmitir la TFC seleccionada excede un nivel de potencia de transmision máxima permitida; y actualizar la lista de TFCs eliminando las TFCs determinadas que tienen un nivel de potencia de transmision que excede el nivel de potencia de transmision máxima permitida. También se divulga un equipo usuario (UE) para seleccionar una combinacion de formato de transporte (TFC) en una comunicacion inalámbrica que emplea al método.
