Abstract
A method is provided for beam tracking in a user equipment (UE), the UE configured to communicate using mmWave in a 5G New Radio (NR) network, the method includes selecting a first beam among a plurality of beams based on a predicted reference signal, perform adaptive filtering on the first beam, and tracking statistical variations in the first beam based on the adaptive filtering.

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.
A User Equipment (UE) for beam tracking in a 5G New Radio (NR) network using mmWave, the UE comprising:
- a transceiver;
- and
- processing circuitry configured to,
- select 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,
- perform adaptive filtering on the first beam, and
- track second statistical variations in the first beam based on the adaptive filtering.
A non-transitory computer-readable medium storing instructions that, when executed by at least one processor of a User Equipment (UE), cause the at least one processor to:
- select 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;
- perform adaptive filtering on the first beam;
- and
- track second statistical variations in the first beam based on the adaptive filtering.
