Conventional networks and devices may be unable to perform DMRS shifting in some modes. For example, when considering two transmissions of multiple TRP modes, if a DMRS symbol for one transmission is shifted due to a collision with a CRS pattern, the alignment of the transmissions may be altered. If DMRS symbols of the transmissions are not aligned, interference or decoding failure may occur. The disclosure enables procedures for performing DMRS shifting in multiple TRP modes. For example, the DMRS symbols of both transmissions may be shifted responsive to determining an overlap for one transmission. Such shifting may enable the alignment of the DMRS locations for both transmissions to enable decoding of the transmissions."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Demodulation reference signal modifications for multiple signaling, multiple transmission reception point operation","description":"This disclosure provides systems, methods, and apparatus, including computer programs encoded on computer storage media, for demodulation reference signal (DMRS) and cell specific reference signal (CR","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-11533156","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.
