The communication apparatus operates a communication cell, generates discovery signals, for use in a cell search procedure, each discovery signal comprising a pair of synchronization signals and a further signal, and transmits each synchronization signal and the further signal in a respective symbol of a radio frame. The symbol in which the further signal is transmitted separated, in the time domain, by no more than half a radio frame from at least one of said pair of synchronization signals."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Communication system","description":"Communication apparatus is disclosed which is suitable for communicating with a mobile communication device in a communication system which uses a plurality of radio frames wherein each radio frame is","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9749976","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.
