CA 2509640

A method for determining uplink power requirements for a transceiver in a wireless communications system includes obtaining measurements from a beacon signal (406) occupying a first timeslot in a frame; obtaining measurements from at least one additional channel (108) having a known transmitted signal strength and occupying a second timeslot in the frame; and utilizing the measurements to determine a path loss estimate (110).

Procédé pour déterminer la demande de puissance de la liaison montante dans un émetteur / récepteur faisant parti d'un système de communications sans fil, qui consiste à obtenir des mesures à partir d'un signal de balise (406) occupant un premier intervalle de temps dans une trame; à obtenir des mesures provenant d'au moins un canal supplémentaire (108) possédant une intensité connue de signal transmis et occupant un deuxième intervalle de temps dans une trame; et à utiliser le résultat de ces mesures pour déterminer une estimation de perte d'affaiblissement sur le trajet (110).
