A wireless communication method and apparatus for reporting traffic volume measurement (TVM) information used to support enhanced uplink (EU) data transmissions between a wireless transmit/receive unit (WTRU), i.e., a mobile station, and a Node-B. After storing EU data in a buffer, the WTRU sends an initial TVM information request message to the Node-B indicating that the WTRU has EU data available to send to the Node-B. In response, the Node-B schedules one or more allowed EU data transmissions. The WTRU transmits at least a portion of the stored EU data to the Node-B via the allowed EU data transmissions. In one embodiment, the initial TVM information request message is sent by the WTRU only after the quantity of EU data stored in the buffer of the WTRU exceeds an established threshold. Otherwise, all of the stored EU data is transferred to the Node-B without requiring scheduling by the Node-B.

L'invention concerne un procédé et un appareil de communication sans fil qui permettent de communiquer des informations de mesure de volume de trafic ("traffic volume measurement" ou TVM) utilisées pour soutenir des transmissions de données montantes améliorées ("enhanced uplink" ou EU) entre une unité d'émission/réception sans fil ("wireless transmit/receive unit" ou WTRU), c'est-à-dire une station mobile, et un noeud B. Après avoir stocké les données EU dans un tampon, l'unité WTRU envoie un message de demande d'informations TVM initial au noeud B indiquant qu'elle a des données EU à lui envoyer. En réponse, le noeud B programme une ou plusieurs transmissions de données EU autorisées. L'unité WTRU transmet au moins une partie des données EU stockées au noeud B via les transmissions de données EU autorisées. Dans un mode de réalisation, le message de demande d'informations TVM initial est envoyé par l'unité WTRU uniquement après que la quantité de données EU stockées dans le tampon de l'unité WTRU a dépassé un seuil établi. Sinon, toutes les données EU stockées sont transférées vers le noeud B sans que ce dernier doive programmer le transfert.
