Only one Physical Downlink Shared Channel (PDSCH) is received on the PCell among the plurality of cells in a first subframe. Hybrid Automatic Repeat Request Acknowledgement (HARQ-ACK) information about the PDSCH is transmitted through a Physical Uplink Control Channel (PUCCH) in a second subframe configured for Scheduling Request (SR) transmission. For a positive SR in the second subframe, the HARQ-ACK information is transmitted using a SR PUCCH resource. For a negative SR in the second subframe, the HARQ-ACK information is transmitted using a HARQ-ACK PUCCH resource different from the SR PUCCH resource."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Method and device for transmitting control information","description":"A method for transmitting uplink control information by a communication apparatus configured with a plurality of cells including a Primary Cell (PCell) and a Secondary Cell (SCell) in a wireless commu","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9756620","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.
