The preamble length can be optimized using a predetermined criterion depending on a transmission gap length (which can be variable) in the discontinuous control signal (e.g., transmitted on the DPCCH) or in a discontinuous data signal, e.g., transmitted on an enhanced dedicated channel (E-DCH), and/or on a length of a transmission timing interval (TTI) of the discontinuous data. Furthermore, a power in the preamble can be changed in time using a further predetermined criterion."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Preamble length for discontinuous control channel transmission","description":"The specification and drawings present a new method, system, apparatus and software product for defining a preamble length of a preamble (e.g., a power control preamble) for a discontinuous control ch","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-8521205","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.
