The method may comprise the steps of: mapping a DMRS sequence to 12 sub-carriers of a physical resource block (PRB); and dividing the PRB, to which the DMRS is mapped, into N sub-PRBs. Here, each of the sub-PRBs may comprise 12/N sub-carriers to which the DMRS is mapped. The method may further comprise a step for transmitting the N sub-PRBs to a base station in N sub-frames."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Method and MTC device for transmitting DMRS for uplink data demodulation","description":"The present specification discloses a method for transmitting a demodulation reference signal (DMRS) for uplink data demodulation by a machine type communication (MTC) device which is configured to op","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-10469222","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.
