5G NR: Scanner-based vs. UE-based field measurements
WebMar 10, 2024 · For downlink channel sounding, 5G NR uses two main downlink signals that a UE measures: . SSB: Transmitted with a low duty cycle on a limited bandwidth compared to LTE's Cell-Specific Reference Signals (CRS) that's sent on the entire channel bandwidth.SSB measurements are used to determine path loss and average channel … WebChannel State Information Reference Signal (CSI-RS) is a reference signal (RS) that is used in the Downlink (DL) direction in 5G NR, for the purpose of Channel Sounding and used to measure the characteristics of a radio channel so that it can use correct modulation, code rate, beam forming etc. WebMar 5, 2024 · Therefore, the RIM-RS resources from neighbour gNBs can be interpreted as scheduled non-zero power CSI-RS resources (NZP CSI-RS) or zero power CSI-RS (ZP CSI-RS). In this context, the 2OS RIM-RS design cannot be used for interference measurements as it breaks the symbol alignment of the 5G NR physical layer. 2.2.3 … challanges 21
