Abstract: A method for adjusting the power of a probe signal to be transmitted by user equipment to system equipment of a wireless communication system. The power of the probe signal is adjusted based on information received by the user equipment from the system equipment. The information is a local mean of RSSI at the system equipment. The adjusted probe signal is transmitted and thus has an increased likelihood of being detected by the system equipment. Also, the power available for transmitting the probe signal is used more efficiently when the probe signal is adjusted in accordance with the local mean information received by the user equipment from system equipment of the wireless communication system.
