Abstract:
A method of implementing downlink frequency hopping to the frequency of a broadcast control channel in a radio system comprising a network part, a subscriber terminal and a radio connection as the transmission path between the network part and the subscriber terminal, the method comprising:A) transmitting by the network part on the broadcast control channel a first signal group to the subscriber terminal at a given frequency, the first signal group indicating at which second frequency a next first signal group will be transmitted the next time, B) transmitting by the network part on the broadcast control channel a known number of other signals to the subscriber terminal using frequency hopping, wherein an offset of a first frequency hop has been agreed in advance, and offsets of other frequency hops are agreed in advance, and C) returning to step A to repeat steps A and B a predetermined number of times to form a frequency hopping sequence, wherein each transmission of the next first signal group to the subscriber terminal occurs at the second frequency identified in a preceding one of the first signal groups.
