Mobility for radio devices using beamforming and selection

A first apparatus comprising a processor, a memory, and communication circuitry, the first apparatus being connected to a communications network via its communication circuitry, the first apparatus further comprising computer-executable instructions stored in the memory of the first apparatus which, when executed by the processor of the first apparatus, cause the first apparatus to:

• a. obtain, via beamforming training, a serving set of beams, the serving set of beams comprising one or more beams for both uplink transmission and downlink reception to and from a second apparatus;
• b. communicate with the second apparatus via the serving set of beams;
• c. maintain a candidate set of beams, the candidate set of beams comprising one or more beams having angles relative to beams of the serving set of beams;
• d. observe a status change of the first apparatus, where the status change is a mobility event or a change in the angle or orientation of the first apparatus;
• and
• e. determine, based on the status change, to communicate with the second apparatus using the candidate set of beams.

An apparatus comprising a processor, a memory, and communication circuitry, the apparatus being capable of connecting to a communications network via its communication circuitry, the apparatus further comprising computer-executable instructions stored in the memory of the apparatus which, when executed by the processor of the apparatus, cause the first apparatus to:

• a. search for one or more cells of the communications network;
• b. measure the quality and level of signals, the signals arriving at the apparatus from one or more beams of the one or more cells;
• c. maintain a list of cells of the communications network;
• d. determine whether to add a first cell to the list of cells based on the suitability of the cell;
• and
• e. select a second cell from the list of cells.
