    Abstract: A method and wireless communication system for providing channel assignment information used to support an uplink (UL) channel and a downlink 5 (DL) channel. The system includes at least one Node-B and at least one wireless transmit/receive unit (WTRU). The WTRU communicates with the Node-B via a common control channel, the UL channel and the DL channel. The WTRU receives a message from the Node-B via the common control channel. The message includes an indication of whether the message is intended for assigning 10 radio resources to the UL channel or the DL channel. The WTRU determines whether the message is intended for the WTRU and, if so, the WTRU determines whether the message is for assigning radio resources to the UL channel or the DL channel. The WTRU takes an appropriate action based on whether the message is for assigning radio resources to the UL channel or the DL channel.

    Abstract: Detecting, avoiding and/or correcting problematic puncturing patterns in parity bit streams used when implementing punctured Turbo codes is achieved without having to avoid desirable code rates. This enables identification/avoidance of regions of relatively poor Turbo code performance. Forward error correction comprising Turbo coding and puncturing achieves a smooth functional relationship between any measure of performance and the effective coding rate resulting from combining the lower rate code generated by the Turbo encoder (600) with puncturing of the parity bits. In one embodiment, methods to correct/avoid degradations due to Turbo coding are implemented by puncturing interactions when two or more stages of rate matching (610, 620) are employed.

    Abstract: Un método y un aparato para senalizacion de informacion indicando los requerimientos de performance a los que una WTRU se acomete a satisfacer desde la WTRU para permitir una más eficiente asignacion de recursos de radio e incrementar la capacidad de la red. La WTRU puede senalizar informacion a la estacion base que incluye los requerimientos de performance que la WTRU se acomete a satisfacer, lo que incluye un codigo o un campo asociado con al menos un requerimiento de performance. En otra incorporacion, la informacion senalizada indica un cambio en los requerimientos de performance acometidos por a WTRU. En otra incorporacion más, la WTRU senaliza mediciones de calidad de canal, tales como mensajes de reportes de indicador de calidad de canal (CQI) a la estacion base, la cual, en turno, infiere cierta informacion referente al performance del receptor con base en las mediciones de calidad de canal.
