In the embodiments of the present invention, a network device first determines a first optimal beam forming vector, and then determines a second optimal beam forming vector from a second beam forming vector set corresponding to the first optimal beam forming vector and performs channel measurement via a formed pilot to determine optimal pre-coding information about a second dimension. Since an optimal beam forming vector therein is determined based on a beam forming vector set with a coarse particle granularity, and then an optimal beam forming vector therein is determined based on a corresponding beam forming vector set with a fine particle granularity, the purpose of determining the optimal beam forming vector with fine particle granularity and the optimal pre-coding information is achieved, which, compared with the prior art, reduces system resource expense, and further reduces the complexity of a user equipment."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Method and apparatus for determining three-dimensional beam pre-coding information","description":"The embodiments of the present invention relate to the field of wireless communications, and more particularly, to a method and apparatus for determining three-dimensional beam pre-coding information ","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9780858","license":"CC-BY-4.0-like","license_terms":"AI-generated analysis on this page (summary, layman_explanation, technical_analysis, business_analysis, faqs) may be reused with attribution and a visible link back to the canonical URL above.
