Abstract:
Systems and methods relating to correction of a Doppler/frequency offset in a wireless communication system are disclosed. In some embodiments, a method of operation of a node comprises estimating a Doppler/frequency offset for a wireless device based on an uplink signal received from the wireless device and providing a frequency adjustment to the wireless device that corrects for the Doppler/frequency offset. In this manner, the Doppler/frequency offset for a wireless device is determined and corrected.
