A method and wireless multi-cell communication system for providing high speed downlink packet access (HSDPA) services (FIG. 1). The system includes a radio network controller (RNC) (105) in communication with a plurality of base stations (110, 115 and 120). The RNC sends a control signal (140A, 140B,and 140C) to at least one base station having a plurality of timeslots, e.g., in a time division duplex (TDD) system and/or frames including transmission timing intervals (TTIs), e.g., in a frequency division duplex (FDD) system assigned thereto for the establishment of HSDPA channels. The control signal indicates a maximum allowed HSDPA transmit power for each of the timeslots and/or TTIs. The base station (110, 115 and 120) sends a feedback signal (145A, 145B and 145C) to the RNC indicating the results of measurements of the power of the transmitted HSDPA timeslots and/or TTIs during a predetermined time period.

L'invention concerne un procédé et un système de communication multicellulaire sans fil pour fournir des services d'accès par paquets de liaison descendante à grande vitesse (HSDPA). Le système comporte une commande de réseau radio (RNC) en communication avec plusieurs stations de base. Le RNC envoie un signal de commande à au moins une station de base ayant plusieurs intervalles de temps, par exemple dans un système duplex à répartition dans le temps (DRT) et/ou des trames renfermant des intervalles de temps de transmission (ITT), par exemple dans un système duplex à répartition en fréquence (DRF) qui lui est attribué pour établir des canaux HSDPA. Le signal de commande indique une puissance maximale d'émission HSDPA autorisée pour chaque intervalle de temps et/ou intervalle de temps de transmission. La station de base envoie un signal de rétroaction au RNC indiquant les résultats des mesures de la puissance des intervalles de temps HSDPA émis et/ou de intervalles de temps de transmission pendant une période prédéterminée.
