A method by which a base station detects a random access channel (RACH) signal in a wireless access system supporting a high frequency band, according to one embodiment of the present invention, comprises the steps of: allocating a cyclic shift value used in the base station; configuring a reception signal vector for signals transmitted through the RACH; deriving a cyclic shift candidate greater than or equal to a reference value from the reception signal vector by using a first detection filter; and detecting the RACH signal from the cyclic shift candidate by using a second detection filter, wherein the first detection filter and the second detection filter can be set on the basis of the cyclic shift value."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Method and device for detecting uplink synchronization signal in each step in wireless access system supporting high frequency band","description":"The present invention provides a method for detecting an uplink synchronization signal in a wireless access system supporting a high frequency band, a method for designing a detection filter for the s","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9680682","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.
