Abstract: A mobile station of a mobile radiocommunication system for receiving synchronization channels transmitted on at least one carrier so as to be able to synchronize with a base station and transmit data in a traffic channel defined with respect to the synchronization channels. The mobile station may transmit synchronization channels on a carrier normally transmitted by a base station. The mobile station may transmit a traffic channel on the carrier. The synchronization and traffic channels are transmitted to at least one other mobile station so the first mobile station can synchronize with the other mobile station and read the traffic channel.

Abstract: The present invention relates to a mobile station of a mobile radiocommunication system of the type comprising means for receiving synchronisation channels transmitted on at least one carrier so as to be able to synchronise with a base station and transmit data in a traffic channel defined with respect to said synchronisation channels. According to the invention, it comprises means for transmitting synchronisation channels on a carrier normally transmitted by a base station, and means for transmitting a traffic channel on said carrier, said synchronisation and traffic channels being transmitted to at least one other mobile station so that the latter can synchronise with said mobile station and read said traffic channel.
