Title
(EN) BEAM REFINEMENT IN A MILLIMETER WAVE CHANNEL
(FR) AFFINEMENT DE FAISCEAU DANS UN CANAL D'ONDE MILLIMÉTRIQUE
Abstract
(EN)
Methods, systems, and devices for wireless communications are described. A communication device may perform a first set of beam measurements for a first plurality of beams over a wireless channel, each beam in the first plurality of beams having a first beam-width. The communication device may transmit a first beam measurement report for the first plurality of beams, the first beam measurement report indicating a beam sweep order for a second set of beam measurements for a second plurality of beams. The communication device may perform the second set of beam measurements for the second plurality of beams over the wireless channel according to the indicated beam sweep order, each beam in the second plurality of beams having a second beam-width that is narrower than the first beam-width.

L'invention concerne des procédés, des systèmes et des dispositifs destinés aux communications sans fil. Un dispositif de communication peut effectuer un premier ensemble de mesures de faisceau lié à une première pluralité de faisceaux sur un canal sans fil, chaque faisceau dans la première pluralité de faisceaux ayant une première largeur de faisceau. Le dispositif de communication peut transmettre un premier rapport de mesure de faisceau destiné à la première pluralité de faisceaux, le premier rapport de mesure de faisceau indiquant un ordre de balayage de faisceau d'un second ensemble de mesures de faisceau destiné à une seconde pluralité de faisceaux. Le dispositif de communication peut effectuer le second ensemble de mesures de faisceau lié à la seconde pluralité de faisceaux sur le canal sans fil selon l'ordre de balayage de faisceau indiqué, chaque faisceau dans la seconde pluralité de faisceaux ayant une seconde largeur de faisceau qui est plus étroite que la première largeur de faisceau.
