摘要：The invention relates to a method of generating a carrier wave of common channels and a radio system. The radio system comprises a network part, subscriber terminals and a bidirectional transmission path between the network part and the subscriber terminal. The bidirectional transmission path consists of frames to be transmitted at a carrier wave frequency. A frame comprises time slots. To a time slot is applied a channel, the channel being either a common channel (FCCH, SCH, BCCH, CCCH) or a dedicated channel (TCH). The carrier wave is generated by adjusting transmission powers of time slots and by using frequency hopping to the effect that first there is transmitted at least one time slot containing a common channel (FCCH, SCH, BCCH, CCCH), with a predetermined reference power. Then, other time slots are transmitted with a transmission power lower than the reference power, and using frequency hopping. In accordance with the invention at least one other time slot determined by the transmission power sequence is transmitted with the reference power, using frequency hopping.
