TRS resources if configured by gnb, is present in two consequtive slots and two symbols per slot. LS estimates from the first symbol is saved and in second symbol frequency offset and time offset is estimated. The estimated FO is saved in UE global structure which is used in the last TRS slot. If the FO is above a threshold, the radio's center frequency is adjusted. Time offset is estimated but not used because time is already tracked using PBCH DMRS.
