The first user equipment comprises a tuner configured to tune a communication unit to channels of a channel sequence vector in order. The channel sequence vector comprises at least a partial vectorization of a symmetric Toeplitz matrix formed from a set of the plurality of channels. The communication unit is configured, at each channel, to receive link data for establishing a communication link with the at least one other user equipment. A link establisher is configured to establish a communication link with the at least one other user equipment over the tuned channel if the link data is received."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Establishing a communication link between user equipments","description":"Methods and apparatus for establishing a communication link between a first user equipment and at least one other user equipment in a radio communication cell using a radio frequency spectrum divided ","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9847857","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.
