Title (EN) POSITIONING OF MOBILE DEVICES
(FR) LOCALISATION DE DISPOSITIFS MOBILES
Abstract: front page image
(EN)A base station transmits, in a repetitive first sequence (501) of transmission frames (202) of a wireless channel, first positioning reference signals (551). The base station transmits, in a repetitive second sequence (502) of transmission frames (202) of the wireless channel, second positioning reference signals (552). The first positioning reference signals (551) and the second positioning reference signals (552) each facilitate determining a time of arrival of signals communicated on the wireless channel.
(FR)Selon l'invention, une station de base émet, dans une première séquence répétitive (501) de trames de transmission (202) d'un canal sans fil, des premiers signaux de référence de localisation (551). La station de base émet, dans une deuxième séquence répétitive (502) de trames de transmission (202) du canal sans fil, des deuxièmes signaux de référence de localisation (552). Les premiers (551) et les deuxièmes signaux de référence de localisation (552) facilitent chacuns la détermination d'un temps d'arrivée de signaux communiqués sur le canal sans fil.
