Abstract
A method includes receiving, from a second device, a signal using each beam of a first subset of beams of a beam set arranged in a layout, measuring a beam quality of the signal received using each beam of the first subset of beams, estimating 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 a beam from the beam set, selecting the beam being in accordance with the measured beam quality and the estimated beam quality, and communicating, with the second device, using the beam.
Claims21
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, the second subset comprising at least one beam whose beam quality is not measured, 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 selected beam.
A first device comprising:
- a non-transitory memory storage comprising instructions;
- and
- one or more processors in communication with the memory storage, wherein the one or more processors execute the instructions to:
- receive, from a second device, a signal using each beam of a first subset of beams of a beam set arranged in a layout;
- measure a beam quality of the signal received using each beam of the first subset of beams;
- estimate 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, the second subset comprising at least one beam whose beam quality is not measured, and the estimating of the beam quality of the signal being in accordance with the measured signal quality of the first subset of beams;
- select a beam from the beam set, selecting the beam being in accordance with the measured beam quality and the estimated beam quality;
- and
- communicate, with the second device, using the selected beam.
