CSI-RS (Channel State Information - Reference Signal): it is used for tracking rapidly changing channel conditions to support mobility and beam management.These measurements are used to determine path loss and average channel quality. SSB (Synchronization signal PBCH block): it is transmitted with a low duty cycle on a limited bandwidth as compared to LTE’s cell-specific reference signals (CRS) that are sent on the entire channel bandwidth.5G capable devices can provide SS-RSRP measurements at Layer 1 when sending Channel State Information (CSI) and at Layer 3 when sending an RRC measurement report to gNB.įor Downlink channel sounding, 5G NR uses two main downlink signals that a UE measures: In 5G NR, RSRP measurement is performed and reported at layer 1 (Physical Layer) and layer 3 (RRC layer). The network configures an RRC CONNECTED UE to perform measurements and UE report measurement report In NR, the measurements that the UE performs can be gap-assisted or non-gap-assisted. The UE needs measurement gaps to perform measurements when it cannot measure the target carrier frequency while simultaneously transmitting/receiving on the serving cell.
