Each of at least two candidate DMRS configuration parameter sets includes a cell identifier and a scrambling identifier. The scrambling identifier included in one of at least two candidate DMRS configuration parameter sets may be determined whether the two cell identifiers included respectively in at least two candidate DMRS configuration parameter sets are the same or not."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Method and apparatus for transmitting or receiving downlink signal","description":"A method for receiving a downlink signal by user equipment in a wireless communication system that supports coordinated multiple-point transmission and reception (CoMP) according to one embodiment of ","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9596064","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.
