In one aspect, a UE determines whether tri-state HARQ feedback or bi-state HARQ feedback is configured based on a DL carrier. The UE generates HARQ feedback for at least one of a received PDCCH or a received PDSCH on the DL carrier based on the determination whether the DL carrier is configured with the tri-state HARQ feedback. The UE transmits the generated HARQ feedback."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Codebook determination for tri-state HARQ-ACK feedback","description":"Aspects presented herein may enhance a HARQ feedback operation to improve data retransmissions by using tri-state HARQ feedback, and may enable a UE to construct a codebook for tri-state HARQ feedback","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-11956082","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.
