In a random access procedure for initial access to a network by the user equipment according to an embodiment of the present invention, the user equipment transmits, two or more times, an RACH preamble signal to a base station, so that a more accurate TA value can be predicted utilizing TA information from two or more response messages received."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Method and apparatus for controlling uplink random access procedure in mobile communication system","description":"A signal transmitting/receiving method of a user equipment of a mobile communication system according to an embodiment of the present invention comprises the steps of: transmitting a first random acce","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9814006","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.
