The present invention provides a communication system, device and method of reverse link symbol timing synchronization of transmited signals to facilitate reverse link timing synchronization. A base unit transmits a forward link signal, receives a reverse link signal, and determines a timing offset for signals received on a reverse link timing synchronization channel, wherein the reverse link synchronization channel comprises a plurality of adjacent reverse link carrier frequencies that are utilized by a multicarrier subscriber unit to facilitate reverse link symbol timing synchronization. A plurality of multicarrier subscriber units receive a forward link signal and transmit a reverse link symbol timing synchronization burst on a reverse link timing synchronization channel wherein the reverse link timing synchronization channel comprises a plurality of adjacent reverse link carrier frequencies that are utilized by each subscriber unit, and adjusts a timing reference for transmitting signals to facilitate reverse link timing synchronization.
La présente invention se rapporte à un système de communications (100), à un dispositif (200) et à un procédé de synchronisation de la temporisation des symboles d'une liaison de retour qui facilitent la synchronisation des signaux de temporisation d'une liaison de retour. Une unité de base (204) émet un signal (160) sur la liaison aval et détermine un décalage de temporisation associé aux signaux reçus sur une voie (150) de synchronisation de la liaison de retour. Une pluralité d'unités (202) d'abonné à porteuses multiples reçoivent un signal (160) sur la liaison aval et émettent une rafale de synchronisation de la temporisation des symboles de la liaison de retour sur une voie de la liaison de retour (160).
