1. A method for adjusting a set of candidate beams that a wireless device is to perform measurements on, the method comprising:
obtaining an estimated gain value associated with a first narrow beam in the set of candidate beams, wherein the estimated gain value is determined based on a value indicative of first received energy of a first reference signal received by the wireless device on a first wide beam and a value indicative of a second received energy of a second reference signal received by the wireless device on the first narrow beam;
comparing the estimated gain value to an expected gain value associated with the first narrow beam, wherein comparing the estimated value to the expected gain value associated with the first narrow beam comprises calculating a ratio between the estimated gain value and the expected gain value; and
based on the comparison, determining whether to adjust which beams belonging to the candidate set of beams.
