APPARATUS AND METHOD FOR DETERMINING A DOWNLINK TRANSMIT POWER CHARACTERISTIC IN A CELLULAR COMMUNICATION SYSTEM

摘要

A cellular communication system comprising a network optimizer (117) which may perform performance optimization or evaluation based on measurements by remote stations (101, 103, 115). The network optimizer (117) comprises a remote station measurement controller (203) which instructs a first remote station (101) to report signal strength measurements for a pilot channel of a serving cell. A resulting signal strength measurement indication for the pilot channel is received from the first remote station (101) by a signal strength processor (207) and a transmit characteristic processor (209) determines a downlink transmit power characteristic for a traffic channel for the remote station in response to the signal strength measurement for the pilot channel. The invention may provide compensation for a dynamic downlink power control for the traffic channel without requiring information of the transmit power used by the base station (103).
