A method of adjusting a reference frequency of a frequency component of a first mobile communications device, wherein the first mobile communications device is configured to communicate with one or more further mobile communications devices via a wireless interface and in accordance with a communication protocol wherein, in accordance with the communication protocol, a first synchronisation signal is provided on the wireless interface for timing and frequency tuning and a reference signal is provided on the wireless interface for channel estimation. The method comprises: receiving, at the first mobile communications device, the first synchronisation signal; adjusting, at the first mobile communications device, the reference frequency of the frequency component based on the received first synchronisation signal; receiving, at the first mobile communications device, the reference signal; estimating, at the first mobile communications device, a frequency offset based on the received reference signal; adjusting, at the first mobile communications device, the reference frequency of the frequency component according to the estimated frequency offset. |
