Abstract:
1. A mobile station of a mobile radio communication system of a type comprising means for receiving a beacon channel comprising at least one frequency correction channel (FCCH), one synchronization channel (SCH), and at least one broadcast control channel (BCCH) 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 a synchronization channels including the least one FCCH and one SCH, said mobile station comprising: means for transmitting a beacon channel comprising at least one FCCH and one SCH on a carrier normally exclusively transmitted by a base station; means for transmitting a traffic channel (TCH) on said carrier, wherein said beacon channel transmitted from said means for transmitting said beacon channel and traffic channel are transmitted to at least one other mobile station so that the latter can synchronise with said mobile station and read said traffic channel; means for, when said mobile station is the first to transmit on a carrier, said mobile station then being known as a master mobile station, transmitting the master mobile station's own beacon channel including at least one FCCH, one SCH, and at least one BCCH in a predefined manner to at least one slave mobile station; means for, when said mobile station is the master mobile station, allocating resource for enabling a requesting mobile station to transmit said requesting mobile station's own beacon channel to at least one other mobile station; and means for, when it is not the first to transmit on a carrier, said mobile station then being known as a slave mobile station, synchronising firstly with the beacon channel of the master mobile station of said carrier before transmitting the slave mobile station's own beacon channel including at least one FCCH, one SCH without including at least one BCCH to other slave mobile station not receiving the master mobile station's own beacon channel.
