Title (EN) TRANSMISSION/RECEPTION APPARATUS AND TRANSMISSION/RECEPTION METHOD FOR ENABLING COEXISTENCE OF SYSTEMS
(FR) EMETTEUR/RECEPTEUR ET PROCEDE D'EMISSION/RECEPTION POUR PERMETTRE LA COEXISTENCE DE SYSTEMES
Abstract:
(EN) An in-home-system master station (111) of an in-home communication system (110) detects a frequency band (a channel number corresponding to a data communication subchannel (212)) or a time slot used by each station of an access communication system (120), using a coexistence signal subchannel (211). Based on the detected information, the in-home-system master station (111) determines a frequency band or a time slot to be used in the in-home communication system (110) to which the in-home-system master station (111) belongs, so as not to avoid overlapping the frequency or time slot used in the access communication system (120), and informs each in-home-system slave station (112) of the determined frequency band or time slot.
(FR) Une station maîtresse (111) d'un système de communication interne de maison (117) détecte une bande de fréquences (un numéro de canal correspondant à un sous-canal de communication de données (212)) ou une tranche de temps utilisée par chaque station d'un système de communication d'accès (120) utilisant un sous-canal pour la coexistence des signaux (211). En fonction des informations détectées, la station maîtresse (111) du système à domicile détermine une bande de fréquences ou une tranche de temps devant être utilisée dans le système de communication interne de maison (110) auquel appartient la station maîtresse (111) de façon à ne pas éviter le chevauchement de la fréquence ou tranche de temps utilisée dans le système de communication d'accès (120), et informe chaque station asservie (112) de la bande de fréquences ou tranche de temps déterminée.
