Title
(EN) METHOD AND APPARATUS FOR INCLUDING SYSTEM INFORMATION IN A FREQUENCY HOPPING SYSTEM
(FR) PROCÉDÉ ET APPAREIL POUR INCLURE DES INFORMATIONS SYSTÈME DANS UN SYSTÈME DE SAUT DE FRÉQUENCE
Abstract
(EN) An access point (12) in a frequency hopping system includes system information based on a target periodicity and a predetermined frequency range. The access point selects frames for system information transmissions from among transmission opportunities within the frequency range as determined according to a frequency hopping sequence. An electronic device (14) monitors frequencies of the frequency range in parallel to detect the system information.
(FR) Selon la présente invention, un point d'accès (12) dans un système de saut de fréquence comprend des informations système fondées sur une périodicité cible et une plage de fréquences prédéterminée. Le point d'accès sélectionne des trames pour des transmissions d'informations système parmi des opportunités de transmission dans la plage de fréquences telles que déterminées selon une séquence de sauts de fréquence. Un dispositif électronique (14) surveille les fréquences de la plage de fréquences en parallèle afin de détecter les informations système.
