Patent attributes
Methods, systems, and devices for wireless communications are described that provide for adjustment of a frequency offset based on switching between uplink/downlink (UL/DL) transmission/reception beam pairs between a UE and a base station. A connection may be established via a first UL/DL transmission/reception beam pair and a frequency tracking loop may be established and maintained to correct for frequency error (e.g., due to Doppler shift) of received transmissions at a receiving device. In cases where a beam switch is performed, and the UE and base station switch from the first UL/DL transmission/reception beam pair to a second UL/DL transmission/reception beam pair, and a frequency offset difference between the first and second UL/DL transmission/reception beam pairs may be applied to the frequency tracking loop. The frequency offset difference may be obtained from a table of frequency offset measurements of multiple UL/DL beam pairs using associated reference signal transmissions.
