The first reference signal is mapped to a same set of antenna ports that are mapped to a second reference signal transmitted on a second set of resource elements of a second EPDCCH to at least a second UE. Furthermore, the first set of resource elements and the second set of resource elements have been selected from shared resource elements. The first set of resource elements differ from the second set of resource elements. The method also includes descrambling the received first reference signal based at least in part on a cell identification (ID) and demodulating a signal based at least in part on the descrambled first reference signal."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Cell ID and antenna port configurations for EPDCCH","description":"A method of wireless communication is provided which includes receiving, at a first user equipment (UE), a first reference signal on a first set of resource elements of a first enhanced physical downl","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9794923","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.
