The method includes: selecting, by a terminal device, a first uplink from at least two preconfigured uplinks to perform random access; and selecting, by the terminal device when random access performed by using the first uplink fails, a second uplink from the at least two uplinks to perform random access, where the at least two uplinks are communications links between the terminal device and a first network device, the first network device and the terminal device are located in a same cell, the first uplink is a normal uplink NUL, and the second uplink is a supplementary uplink SUL. In this way, the terminal device selects an uplink to perform random access."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Random access method and apparatus","description":"This application relates to the wireless communications field, and discloses a random access method and apparatus, to resolve a problem of how a terminal device selects an uplink to perform random acc","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-11490415","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.
