Abstract
A method (30) for analog beamfinding performed by a device (1, 2) is provided. The method (30) comprises performing (31) one or more one-dimensional beam sweeps in a first direction, performing (32) one or more one-dimensional beam sweeps in a second direction, and determining (33) a two-dimensional beam based on at least one one-dimensional sweep in the first direction and at least one one-dimensional sweep in the second direction. A corresponding device (1, 2), computer program (42) and computer program product (41) are also provided.

A method for analog beamfinding performed by a device, the method comprising:
- performing one or more one-dimensional beam sweeps in a first direction;
- performing one or more one-dimensional beam sweeps in a second direction;
- determining a two-dimensional beam based on at least one one-dimensional sweep in the first direction and at least one one-dimensional sweep in the second direction, wherein the determining comprises:
- selecting one of the one-dimensional beam sweeps in the first direction and one of the one-dimensional beam sweeps in the second direction;
- and
- determining a pointing direction for use in transmission or reception based on the respective pointing directions of the selected one-dimensional beams;
- and
- refining the determined two-dimensional beam by performing a two-dimensional beamsearch using one or more two-dimensional beams based on the determined two-dimensional beam.
