Techniques for selecting a reverse link (RL) serving base station for a terminal are described. The terminal sends a transmission on the reverse link to multiple base stations in a wireless communication system. The transmission may be for signaling sent on a control channel. The terminal receives feedback (e.g., power control (PC) commands and/or erasure indications) from the multiple base stations. Each base station may generate feedback based on the control channel and/or some other transmission received from the terminal. The terminal performs reverse link power control and further selects an RL serving base station based on the received feedback. For example, the terminal may select the base station with the lowest transmit power level, the largest percentage of power down commands, or the lowest erasure rate as the RL serving base station.
L'invention concerne des techniques permettant de sélectionner une station de base de desserte de liaison retour (RL) pour un terminal. Le terminal envoie une transmission sur la liaison retour vers plusieurs stations de base dans un système de communication sans fil. La transmission peut être destinée à signaler des éléments envoyés sur un canal de commande. Le terminal reçoit un retour (par exemple, des commandes de régulation de puissance (PC) et/ou des indications de suppressions) en provenance des multiples stations de base. Chaque station de base peut générer un retour en fonction du canal de commande et/ou d'une autre transmission reçue à partir du terminal. Le terminal effectue la régulation de puissance de liaison retour et sélectionne ensuite une station de base de desserte RL en fonction du retour reçu. Par exemple, le terminal peut sélectionner la station de base présentant le niveau de puissance d'émission le plus faible, le pourcentage le plus important de commandes d'interruption, ou le taux de suppression le plus faible en tant que station de base de desserte RL.
