发明名称 FOERFARANDE OCH UTRUSTNING FOER SYNKRONISERING OCH OEVERFOERING AV INFORMATION I ETT RADIOKOMMUNIKATIONSNAET
摘要 The invention relates to a method and equipment for synchronizing and transmitting information in a radio communication network with fixed base stations (BS1, BS2) and movable mobile stations (MS1, MS2) as well as a plurality of radio channels, the base stations in said communication network being organized in a cellular system, and depending on the cellular system share in time multiplex a radio control channel such that each base station disposes over a frame with time slots within a super frame on the radio control channel. The base stations are synchronized by their receiving call and control signals transmitted on the radio control channel from other base stations during their frames, and time differences between internal time references in the base stations are determined with the aid of the received call and control signals. In accordance with the invention the transmission between the base stations and mobile stations takes place in time multiplex. Analogue information is digitalized before transmission. Information which is to be transmitted on a radio traffic channel is encoded before the transmission using an error-correcting code extending over two or more successive time slots of a mobile station on the radio traffic channel.
