1. A method for beam tracking in a user equipment (UE), the UE configured to communicate using mmWave in a 5G New Radio (NR) network, the method comprising:
selecting a first beam among a plurality of beams based on a predicted received signal power of a first signal, the first signal being a synchronization signal or a reference signal, the predicted received signal power being based on first statistical variations in the first beam, the first statistical variations corresponding to a first slot, the predicted received signal power corresponding to a second slot, and the first slot preceding the second slot;
performing adaptive filtering on the first beam; and
tracking second statistical variations in the first beam based on the adaptive filtering.
