Title
(EN) APPARATUS AND METHOD FOR REDUCING INTERFERENCE IN A WIRELESS COMMUNICATION SYSTEM
(FR) APPAREIL ET PROCÉDÉ DE RÉDUCTION D'INTERFÉRENCE DANS UN SYSTÈME DE COMMUNICATIONS SANS FIL
Abstract
(EN) In a communication system, an access point in communication with one or more stations identifies a first subset of wireless stations from the set of wireless stations. The first subset of wireless stations is identified based on RSSI (Receive Signal Strength Intensity) values for radio frequency signals received from each of the stations exceeding an RSSI threshold (720). The first subset of wireless stations is assigned to a first reception window (730). The access point transmits an identifier of each of the subset of wireless stations and an identifier of the reception window via the radio frequency channel.
(FR) Dans un système de communication, un point d'accès en communication avec une ou plusieurs stations identifie un premier sous-ensemble de stations sans fil dans l'ensemble de stations sans fil. Le premier sous-ensemble de stations sans fil est identifié d'après des valeurs RSSI (intensité de signal de réception) de signaux radiofréquence reçus de chacune des stations excédant un seuil RSSI (720). Le premier sous-ensemble de stations sans fil est attribué à une première fenêtre de réception (730). Le point d'accès transmet un identifiant de chacun des sous-ensembles de stations sans fil et un identifiant de la fenêtre de réception via le canal radiofréquence.
