WHAT IS CLAIMED IS:

1. A method implemented by a first device, the method comprising:

receiving, by the first device, from a second device, a signal using each beam of a first subset of beams of a beam set arranged in a layout;

measuring, by the first device, a beam quality of the signal received using each beam of the first subset of beams;

estimating, by the first device, a beam quality of the signal for each beam of a second subset of beams of the beam set, the first subset of beams and the second subset of beams comprising different beams, and the estimating being in accordance with the measured signal quality of the first subset of beams;

selecting, by the first device, a beam from the beam set, selecting the beam being in accordance with the measured beam quality and the estimated beam quality; and communicating, by the first device, with the second device, using the beam.

2. The method of claim t, the first subset of beams and the second subset of beams being disjoint.

3. The method of any one of claims t-2, a coverage area of each beam of the second subset of beams partially overlapping a coverage area of at least two beams of the first subset of beams.

4. The method of any one of claims 1-3, estimating the beam quality comprising, for each beam of the second subset of beams, determining the estimated beam quality of the beam of the second subset of beams as a combination of the measured beam quality of the at least two beams of the first subset of beams having a coverage area that partially overlaps a coverage area of the beam of the second subset of beams.

5. The method of claim 4, wherein the combination includes one of a sum, a weighted sum, a product, a weighted product, a linear combination, or a non-linear combination, of the measure beam quality of the at least two beams.

6. The method of claim 5, the estimated beam quality being a weighted sum of the measured beam quality of the at least two beams, and the method further comprising determining, by the first device, a weighting factor for each beam of the first subset of beams.

7. The method of any one of claims 1-6, wherein the beam quality comprises at least one of a signal plus interference to noise ratio (SINR) of the signal, a signal to noise ratio (SNR) of the signal, a reference signal received power (RSRP) of the signal, a reference signal received quality (RSRQ) of the signal, or a received signal power of the signal.

8. The method of any one of claims 1-7, the first device being a user equipment (UE), and the second device being an access node.

9. The method of any one of claims 1-8, the beam set comprising 9 beams arranged in a 3x3 grid layout, and the first subset of beams comprising 4 beams arranged in a diamond layout.

to. The method of any one of claims 1-8, the beam set comprising 9 beams arranged in a 3x3 grid layout, and the first subset of beams comprising 5 beams arranged in a diagonal layout.

11. A method implemented by a first device, the method comprising:

receiving, by the first device, from a second device, a signal using each beam of a first subset of a set of 7 beams arranged in a hexagonal layout;

determining, by the first device, a beam quality of the signal received using the first subset of the set of 7 beams;

selecting, by the first device, a beam from the set of 7 beams, selecting the beam being in accordance with the beam qualities; and

communicating, by the first device, with the second device, using the one beam .

12. The method of claim 11, the first subset of the set of 7 beams comprising all 7 beams of the set of 7 beams, and determining the beam quality comprising measuring the beam quality of the signal received using each beam of the set of 7 beams.

13. The method of claim 11, determining the beam quality comprising:
