The terminal device in communication with the base station monitors a physical downlink control channel placed in a common search space and an enhanced physical downlink control channel placed in a terminal-specific search space. Upon detecting the enhanced physical downlink control channel, the terminal device maps response information to a physical uplink control channel resource determined in response to at least an index of an element forming the detected enhanced physical downlink control channel and an individual shift amount individually configured on a per terminal device basis, and then reports the base station of the mapped response information."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Terminal device, base station, communication system, and communication method","description":"The present invention provides a base station, a terminal device, a communication system, and a communication method configured to efficiently specify a physical uplink control channel resource in a c","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9832001","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.
