Abstract:
User Equipment and method for time and frequency synchronization, the method includes: a UE measuring a primary measurement reference signal transmitted on at least one basic sub-band, where the at least one basic sub-band has a preset carrier numerology and a preset waveform configuration; calculating a first time deviation and a first frequency deviation between the UE and a base station on the at least one basic sub-band, based on a measurement result obtained by measuring the primary measurement reference signal; and keeping the UE in time and frequency synchronization with the base station on the at least one basic sub-band, based on the first time deviation and the first frequency deviation. Accordingly, time and frequency synchronization between UE and base station in a 5G system can be achieved.
