The transmission plan includes spreading transmissions of the location beacon that are unique to respective base stations. The mobile station identifies the base stations based on the respective location beacons and the transmission plan. The mobile station identifies a present location based on the location beacons and the identities of the base stations that from which the location beacons were received."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Location determination in wireless communication systems","description":"Briefly, in accordance with one or more embodiments, a mobile station receives a location beacon transmitted from multiple base stations based on a transmission plan for a predefined downlink location","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-8477690","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.
