Beschreibung
Zusammenfassung:	An apparatus configured to; based on a first signal comprising one or more data transmission frames received from a first radio device by a second radio device, the first signal having a particular carrier frequency of a carrier wave thereof and the one or more data transmission frames comprising a plurality of symbols provided at a particular symbol frequency, the carrier frequency and symbol frequency based on a reference clock frequency of the first radio device; determine one or more of an estimate of the particular carrier frequency and an estimate of the particular symbol frequency relative to a reference clock frequency of the second radio device and provide for transmission of a response signal from the second radio device to the first radio device, the response signal provided with one or more of a reply carrier wave having a carrier frequency comprising the determined estimate of the particular carrier frequency and a plurality of symbols of one or more data transmission frames of the response signal provided at a reply symbol frequency comprising the determined estimate of the particular symbol frequency.
