Problems solved by technology

[0004] However, when the existing beam scanning method determines the transmission beam of the millimeter-wave base station, the millimeter-wave base station needs to transmit a system configuration signal to the user equipment through multiple candidate beams to determine a suitable beam, so it takes a lot of time, resulting in The initial access process of the user equipment has a large delay

Embodiment Construction

[0037] The beam selection method and device provided in the embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0038] In the embodiments of the present invention, words such as "exemplary" or "for example" are used as examples, illustrations or illustrations. Any embodiment or design solution described as "exemplary" or "for example" in the embodiments of the present invention shall not be construed as being more preferred or more advantageous than other embodiments or design solutions. Rather, the use of words such as "exemplary" or "such as" is intended to present related concepts in a concrete manner.

[0039] The term "and / or" in this article is just an association relationship describing associated objects, which means that there can be three relationships, for example, A and / or B can mean: A exists alone, A and B exist simultaneously, and there exists alone B these three situations. The symbol " / " in th...

Abstract

The invention provides a wave beam selection method and apparatus, and relates to the technical field of communication. The delay of initial access flow of user equipment can be shortened. The methodcomprises the following steps: selecting a millimeter waves base station for providing service for the user equipment according to the position information of the user equipment; respectively inputting the position information of the user equipment in a plurality of n classifiers corresponding to the millimeter waves base station, and obtaining the wave beam having the highest votes in the sendingwave beams of the millimeter waves base station to serve as a first target wave beam according to judgment results output by the plurality of n classifiers; and sending indication information used for indicating the first target wave beam selected by the user equipment for the millimeter waves base station to the millimeter waves base station. Each n classifier is used for judging the category towhich a wave beam corresponding to the position information of the user equipment belongs in n categories of the n classifier, the n categories correspond to n sending wave beams of the millimeter waves base station, and n is an integer greater than or equal to 2. The wave beam selection method and apparatus provided by the invention are applied to wave beam selection.

Description

technical field [0001] The present invention relates to the field of communication technologies, in particular to a beam selection method and device. Background technique [0002] At present, microwave frequency bands below 6 GHz are mainly used in mobile communication systems (the use of frequency bands below 3 GHz is more common). The shortage of spectrum resources is becoming more and more serious, which greatly limits the support for high data rate services. The millimeter wave frequency band is located in 30GHz-300GHz, with a large number of available spectrum resources, which can fully alleviate the increasingly serious pressure on spectrum resources and meet the demand for high-bandwidth and high-speed business support. [0003] In the mobile communication system, before the user equipment (such as a mobile phone and other communication terminals) establishes a stable data transmission connection with the base station, it needs to go through the initial access proces...
