Abstract
(EN)
A first apparatus may communicate with a user equipment (UE) through an active beam. The first apparatus may transmit, to the UE, information indicating a periodicity at which control information is to be communicated on a control channel through a control-information beam. The first apparatus may communicate, with the UE, the control information on the control channel through the control-information beam at the periodicity. Further, the first apparatus may receive a request to change the active beam, which may indicate a beam index corresponding to a second beam, and the first apparatus may change the active beam to the second beam corresponding to the beam index indicated by the request.

(FR)
Selon l’invention, un premier appareil peut communiquer avec un équipement utilisateur (UE) par l’intermédiaire d’un faisceau actif. Le premier appareil peut transmettre, à l’UE, des informations indiquant une périodicité à laquelle des informations de commande doivent être communiquées sur un canal de commande par l’intermédiaire d’un faisceau d’informations de commande. Le premier appareil peut communiquer, avec l’UE, les informations de commande sur le canal de commande par l’intermédiaire du faisceau d’informations de commande à la périodicité. En outre, le premier appareil peut recevoir une requête pour changer le faisceau actif, qui peut indiquer un indice de faisceau correspondant à un second faisceau, et le premier appareil peut changer le faisceau actif en le second faisceau correspondant à l’indice de faisceau indiqué par la requête.
