Abstract
(EN) Embodiments of the present invention relate to the technical field of communications. Provided are a method, apparatus, device and system for acquiring a beam identifier. The method comprises: a base station determines a signal corresponding to a beam identifier; the base station sends the signal via a beam corresponding to the beam identifier, such that a user equipment detecting the signal acquires, according to the signal, the beam identifier; and when receiving the beam identifier fed back by the user equipment, the base station communicates with the user equipment via the beam corresponding to the beam identifier. In the present invention, a base station determines a signal corresponding to a beam identifier and sends the signal via a beam corresponding to the beam identifier, a user equipment detecting the signal is capable of acquiring the beam identifier and then feeds back same to the base station, and the base station can determine a beam where the user equipment is currently located, and can further communicate with the user equipment via the beam.
(FR) Selon des modes de réalisation, la présente invention se rapporte au champ technique des communications. L’invention concerne un procédé, un appareil, un dispositif et un système d’acquisition d’identifiant de faisceau. Le procédé consiste : en ce qu’une station de base détermine un signal correspondant à un identifiant de faisceau ; en ce que la station de base envoie le signal par le biais d’un faisceau correspondant à l’identifiant de faisceau, de sorte qu’un équipement d’utilisateur détectant le signal acquière, en fonction du signal, l’identifiant de faisceau ; et lors de la réception de l’identifiant de faisceau renvoyé par l’équipement d’utilisateur, en ce que la station de base communique avec l’équipement d’utilisateur par le biais du faisceau correspondant à l’identifiant de faisceau. Selon la présente invention, une station de base détermine un signal correspondant à un identifiant de faisceau et envoie le signal par le biais d’un faisceau correspondant à l’identifiant de faisceau, un équipement d’utilisateur détectant le signal peut acquérir l’identifiant de faisceau et le renvoyer à la station de base, et la station de base peut déterminer un faisceau à l’endroit où l’équipement d’utilisateur est actuellement situé, et peut en outre communiquer avec l’équipement d’utilisateur par le biais du faisceau.
