摘要
The present disclosure relates to reference signalling in mobile communications, to transmitting and receiving uplink reference signals in a multi-carrier system by adapting the subcarrier frequency spacing of the reference elements used for transmitting the reference signal. The disclosure also relates to corresponding devices and a computer program for executing the proposed methods, and a carrier containing said computer program. The disclosure proposes a method, for use in a wireless device, for transmitting a reference signal. The method comprises receiving information indicating a frequency subcarrier spacing, determining a sequence of a reference signal based on the received information and transmitting the reference signal to a network node. The disclosure also proposes a method, for use in a network node, for receiving a reference signal by obtaining information indicating a frequency subcarrier spacing, transmitting the obtained information to a wireless device and receiving the reference signal from the wireless device.
