Abstract
The present invention relates to a method for sending reserved sub-carriers to a UE for the purpose of reducing peak to average power ratio (PAPR) of the transmitted signal to ensure sufficient quality of the modulated signal to achieve high data rate, including the steps of sending the information related to dynamic activation and deactivation of reserved sub-carriers on a common channel, which is readable for all UEs in idle and in connected mode; dynamically activating the transmission of the reserved sub-carriers in a cell when high modulation quality is to be maintained; dynamically deactivating the transmission of the reserved sub-carriers in a cell when high modulation quality is not required. The invention furthermore relates to a radio base station and a UE relating to said method.
