CA 2574104

A method and apparatus for enhanced uplink multiplexing are disclosed. A set of combinations of MAC-d flows (and/or logical channels) that are allowed to be multiplexed within a MAC-e PDU is defined for a WTRU. The WTRU MAC-e entity selects a combination among a set of allowed combinations for multiplexing MAC- d flows for each MAC-e PDU. Certain MAC-d flow combinations may be defined that can not be blocked from transmission even when the WTRU is in a transmit power restricted state. The amount of data from each logical channel or corresponding MAC-d flow that can be multiplexed within a MAC-e PDU may be defined to ensure guaranteed data rates. When the WTRU is in a restricted power condition, an indication of the restricted power condition may be passed to the Node-B with the EU transmission.

Cette invention concerne un procédé et un dispositif de multiplexage en liaison montante amélioré. Un ensemble de combinaisons de flux MAC-d (et)/ou de canaux logiques) pouvant être multiplexé au sein d'une MAC-e PDU est défini pour un WTRU. L'entité WTRU MAC-e sélectionne une combinaison parmi l'ensemble de combinaisons autorisées pour le multiplexage de flux MAC-d pour chaque MAC-e PDU. Certaines combinaisons de flux MAC-d peuvent être définies, dont la transmission ne peut être bloquée même lorsque la WTRU se trouve en condition de puissance de transmission restreinte. Le volume de données tiré de chaque canal logique ou flux MAC-d correspondant pouvant être multiplexé au sein d'une MAC-e PDU peut être défini pour qu'il assure des débits de données garantis. Lorsque la WTRU se trouve en condition de puissance restreinte, une indication correspondante peut être transmise au noeud B avec la transmission EU.
