摘要：
In a synchronization scheme, for example for establishing a channel in a UMTS radio communication system, when a user device (or user equipment, UE) such as a mobile terminal is establishing a channel with a network, the user device transmits signals on the uplink DPCCH, and the power of these signals is ramped up from a calculated initial power level until the transmission is detected by the receiver, i.e. until the receiver has obtained synchronization to the uplink signal.
