CA 2534085

A method and system for an enhanced uplink (EU) operation in a wireless communication system during soft handover. The system comprises a wireless transmit/receive unit (WTRU), at least two Node-Bs, and a radio network controller (RNC). One Node-B may be designated as a primary Node-B, and the primary Node-B may control EU operation during soft handover including uplink scheduling and hybrid automatic repeat request (H-ARQ). Soft buffer corruption is avoided during soft handover by controlling H-ARQ by the primary Node-B. Alternatively, an RNC may control EU operation during soft handover including H-ARQ. In this case, an RNC generates final acknowledge/non-acknowledge (ACK/NACK) decision based on the error check results of the Node-Bs.

L'invention concerne un procédé et un système destinés à une opération de liaison montante améliorée (EU) dans un système de communication sans fil, au cours d'un transfert en douceur. Le système comprend un émetteur-récepteur sans fil (WTRU); au moins deux noeuds-B; et un contrôleur de réseau radioélectrique (RNC). Un des noeuds-B peut être désigné noeud-B principal, et le noeud-B principal peut contrôler l'opération EU au cours d'un transfert en douceur comprenant une programmation de la liaison montante et une demande de répétition automatique mixte (H-ARQ). Une corruption de tampon mou est évitée au cours d'un transfert en douceur, grâce au contrôle de la H-ARQ par le noeud-B principal. En variante, un RNC peut contrôler l'opération EU au cours d'un transfert en douceur avec H-ARQ, auquel cas le RNC génère une décision d'admission/non admission (ACK/NACK) basée sur les résultats de contrôle d'erreurs des noeuds-B.
