The response signal is spread with a sequence defined by a cyclic shift value that is determined among multiple cyclic shift values from an index of physical uplink control channel (PUCCH), which is associated with a first CCE number of aforementioned one or more CCEs, and with an orthogonal sequence that is determined among multiple orthogonal sequences from the index. One of cyclic shift values used for an orthogonal sequence is determined from an index of the PUCCH, which is associated with an odd CCE number and another one of the cyclic shift values used for the same orthogonal sequence is determined from an index of the PUCCH, which is associated with an even CCE number."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Base station apparatus and response signal receiving method","description":"A base station apparatus transmits control information to a radio communication apparatus on one or more control channel elements (CCEs) with consecutive CCE number(s) and receive a response signal fr","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-8509285","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.
