More specifically, the present invention provides a method for transmitting and receiving a DMRS and an apparatus using the same, wherein a base station allocates a Walsh sequence for each antenna port to the DMRS for each antenna port using a method that is different from conventional methods, and thereby increases the number of user equipment that are MU-MIMO paired compared to the past, and can satisfy orthogonality between four DMRS sequences in both time and frequency domains so that user equipment receiving the DMRS can efficiently estimate a channel."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Method for transmitting and receiving demodulation reference signal, and apparatus using same","description":"The present invention relates to a wireless communication system, and specifically provides a method for transmitting and receiving a demodulation reference signal (DMRS), and an apparatus using the s","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-10469225","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.
