Title
(EN) COMMUNICATION SYSTEM WITH BEAM QUALITY MEASUREMENT
(FR) SYSTÈME DE COMMUNICATION AVEC MESURE DE QUALITÉ DE FAISCEAU
Abstract
(EN) A method, performed by a communication device, comprising a) measuring a respective beam quality for each of a plurality of beams of a cell, b) identifying, within said plurality of beams, a first group of beams comprising a number, N, of beams, c) selecting, from within said first group of beams, a second group of beams comprising a number, M, of beams, and d) deriving a cell quality for the cell based on the measured beam qualities for the M beams of the second group.
(FR) L'invention concerne un procédé mis en œuvre par un dispositif de communication, comprenant a) mesure d'une qualité de faisceau respective pour chaque faisceau d'une pluralité de faisceaux d'une cellule, b) identification, à l'intérieur de ladite pluralité de faisceaux, d'un premier groupe de faisceaux comprenant un nombre N de faisceaux, c) sélection, au sein dudit premier groupe de faisceaux, d'un deuxième groupe de faisceaux comprenant un nombre M de faisceaux, et d) déduction d'une qualité de cellule pour la cellule sur la base des qualités de faisceau mesurées pour les M faisceaux du deuxième groupe.
