For example, a base station (eNB) may determine that a UE is configured to receive or transmit data with 16-QAM modulation via capability signalling from the UE. Upon performing this determination, the eNB transmits configuration data to the UE, e.g., via DCI, configuring the UE to receive data over a narrowband physical downlink shared channel (NPDSCH) using 16-QAM modulation. Part of the configuration data indicates whether the UE is to support 16-QAM modulation with or without repetition via radio resource control (RRC) parameter modulation-restriction-Repetitions. Depending upon this indication, the UE may use quadrature phase-shift keying (QPSK) rather than 16-QAM despite selecting or being assigned a TBS based on 16-QAM modulation."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Modulation adjustment for 16-QAM in narrowband IoT","description":"Techniques of defining a transmission scheme for NB-IoT data include determining the TBS based on 16-quadrature amplitude modulation (QAM) analysis but use quadrature phase-shift keying (QPSK) for mod","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-11502892","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.
