In an example, a wireless transmit/receive unit (WTRU) may generate a reference sequence. Further, the WTRU may generate a DMRS sequence based on upsampling of the reference sequence. In an example, the DMRS sequence may include a plurality of repeating sequences. Further, in an example, each repeating sequence may include a head sequence, a reference sequences and a tail sequence. Also, a UW sequence within the DMRS may include one of the repeated head sequences and one of the repeated tail sequences. In addition, the WTRU may generate a DMRS signal based on a waveform operation on the DMRS sequence. The WTRU may then transmit the DMRS signal as a reference signal."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Methods and procedures to improve physical layer efficiency using unique word (UW) discrete fourier transform spread orthogonal frequency division multiplexing (DFT-S-OFDM)","description":"Methods, devices, and systems for transmitting information using a unique word (UW) with discrete Fourier transform spread orthogonal frequency division multiplexing (DFT-s-OFDM) are described herein.","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-10536315","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.
