Abstract:
A method of generating a carrier wave of common channels by adjusting transmission powers of time slots and by using frequency hopping in a radio system, the radio system comprising a network part, at least one subscriber terminal and a bidirectional transmission path between the network part and the subscriber terminal, and the network part comprising at least one base station, and the bidirectional transmission path consisting of frames to be transmitted on the carrier wave frequency, the frame comprising time slots to which a channel is applied, the channel being either a common channel or a dedicated channel, and the method comprising:transmitting at least one time slot containing a common channel with a predetermined reference power without using frequency hopping, transmitting other time slots with a transmission power lower than the predetermined reference power, using frequency hopping, and transmitting at least one other time slot with the predetermined reference power by using frequency hopping.
