Abstract:
1. A method of broadcasting radio signals from a radio-communication base station, on a time-division multiplexing physical control channel, the method comprising the steps of: dividing up the physical control channel into timeslots comprising a set of at least two presynchronization slots and a set of at least two synchronization supplement slots; transmitting, on said physical control channel, synchronization signals for frequency- and time-synchronization of mobile terminals and signals representing system information required for operation of the mobile terminals with the base station, wherein each presynchronization slot carries the same synchronization signal, wherein each synchronization supplement slot carries the same signal representing system information and furthermore a signal identifying said synchronization supplement slot, and wherein each presynchronization slot is associated with a respective synchronization supplement slot with respect to which said presynchronization slot exhibits a fixed time offset.
