Embodiment Construction

[0054] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0055] It should be noted that all directional indications (such as up, down, left, right, front, back...) in the embodiments of the present invention are only used to explain the relationship between the components in a certain posture (as shown in the accompanying drawings). Relative positional relationship, movement conditions, etc., if the specific posture changes, the directional indication will also change accordingly.

Abstract

The invention belongs to the technical field of communication, and particularly relates to a two-stage beamforming method. The two-stage beamforming method comprises the following steps: carrying out space-time block coding on a to-be-sent data stream to obtain a coded data stream; constructing a two-stage beamforming matrix corresponding to a uniform rectangular antenna array; and performing beamforming on the coded data stream through the two-stage beamforming matrix to generate a to-be-transmitted signal of the uniform rectangular antenna array. According to the method, high-reliability and high-efficiency transmission of a common signal can be realized, and compared with direct application of traditional directional beamforming, the transmission efficiency of the common signal is improved because the main lobe of the beam is widened, the coverage angle area is enlarged and the beam scanning frequency is reduced; compared with direct application of omni-directional beamforming, certain beam gain is obtained, the transmission reliability of the common signal is improved, and therefore the performance of the whole network is improved.

Description

technical field [0001] The invention belongs to the technical field of communication, and in particular relates to a two-stage beam forming method. Background technique [0002] Large-scale antennas are one of the key technologies to realize 5G commercial use. In order to realize the commercialization of large-scale antennas, the antennas tend to use uniform rectangular arrays. For base stations deploying uniform rectangular antenna arrays, realizing the transmission of common signals is one of the key factors to improve the overall network performance. Therefore, it is an urgent problem to be solved how the base station realizes the highly reliable and efficient transmission of public signals under the uniform rectangular antenna array. Contents of the invention [0003] The main purpose of the present invention is to provide a two-stage beamforming method, which aims to solve the technical problem that the base station in the prior art cannot realize the high reliabili...
