METHOD OF OPERATING A COMMUNICATION SYSTEM, A RADIO STATION, AND A RADIO COMMUNICATION SYSTEM

摘要

A radio communication system has a plurality of transmission formats available for the transmission of data signals by a sending station, and a pilot signal is transmitted to enable channel estimation by the receiving station. A receiving station transmits a control signal indicating the transmission formats that the sending station may use for transmitting the data signals. The sending station selects one of the indicated transmission formats for transmitting a data signal and derives a transmission power level for the pilot signal from the control signal. The transmission power level of the pilot signal may be independent of the selected transmission format, or may depend on selected transmission format.
