Forward link transmission power to a user terminal (124a, 124b, 124c) in a wireless communications system (100) having a plurality of beams (2041-20416) is controlled by identifying the location of a user terminal within one of the plurality of beams (2041-20416), and setting the forward link (404) transmission power in response to the identified user terminal location. Identifying user terminal location (402, 502) may include receiving from the user terminal multiple signal power measurements (602), such as pilot signal measurements. From these measurements, a difference is calculated between a first of the signal power measurements that corresponds to a home beam and each of the other signal power measurements (604). If the largest of the calculated differences is greater than a predetermined threshold (606), it is concluded that the user terminal is within a beam central region (610). However, if the largest of the calculated differences is less than or equal to the predetermined threshold (606), then it is concluded that the user terminal is within a beam crossover region (608).

Une puissance d'émission en liaison aval vers un terminal usager (124a, 124b, 124c) dans un système de télécommunication sans fil (100) ayant une pluralité de faisceaux (204¿1? 204¿16?) est réglée en identifiant l'emplacement d'un terminal usager dans l'une des pluralités de faisceaux (204¿1? 204¿16?) et en réglant la puissance de transmission en liaison aval (404) en réponse à l'emplacement du terminal usager identifié. L'identification de l'emplacement du terminal usager (402, 502) peut comprendre la réception, en provenance du terminal usager, des mesures de puissance de signaux multiples (602), telles que des mesures de signaux pilotes. A partir de ces mesures, on calcule une différence entre une première des mesures de puissance des signaux, laquelle correspond à un faisceau initial, et chacune des autres mesures de puissance des signaux (604). Si la plus grande des différences calculées est supérieure à un seuil prédéterminé (606), on en déduit que le terminal usager se situe dans une région centrale des faisceaux (610). Par ailleurs, si la plus grande des différences calculées est inférieure ou égale au seuil prédéterminé (606), on en déduit que le terminal usager est dans une région d'intercommunication des faisceaux (608).
