1. A method, comprising:
- configuring a terminal device of a cellular telecommunication system to applya sounding reference signal configuration used for transmitting a dynamically scheduled sounding reference signal from the terminal device to a base station, anda second sounding reference signal configuration used for transmitting a second sounding reference signal periodically in a semi-static manner from the terminal device to the base station,wherein the both sounding reference signal configurations are in parallel use; and
utilizing, in connection with the scheduling of the transmission of the sounding reference signal, a downlink control message transmitted to the terminal device regardless of whether or not uplink data transmission is scheduled to the terminal device at the same time.

Abstract
The present invention is related to configuration of uplink sounding reference signal transmissions in a modern cellular telecommunication system. A terminal device of a cellular telecommunication system is configured to apply a sounding reference signal configuration used for transmitting a dynamically scheduled sounding reference signal from the terminal device to a base station. In connection with the scheduling of the transmission of the sounding reference signal, the present invention utilizes a downlink control message transmitted to the terminal device regardless of whether or not uplink data transmission is scheduled to the terminal device at the same time.
