The method comprises: creating a random access preamble such that it comprises a plurality of random access sequences; dividing the plurality of random access sequences into a number Nc of groups, each of groups including two or more random access sequences; performing code division multiplexing with respect to the groups of the plurality of random access sequences in a frequency domain, based on an orthogonal cover code selected for the terminal device from a pre-defined code set; and transforming signals after the code division multiplexing into the time domain. According to an aspect of the present disclosure, there are provided corresponding methods and devices."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Methods and devices for generating and detecting random access preambles","description":"One embodiment of the present disclosure relates to a method for transmitting a random access preamble in a transmitting sub-frame at a terminal device.
