A method for transmitting a preamble by a user equipment to a base station is provided. The method comprises: selecting a random access resource for transmitting a preamble; determining one root sequence allocated to the random access resource based on a mapping relationship between root sequences and random access resources; generating a preamble based on the root sequence; and transmitting the preamble on the random access resource. The mapping relationship is established based on a rule that a random access resource carries preambles generated from a same root sequence."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Method and apparatus for preamble determination","description":"Methods and apparatuses for preamble determination have been provided.
