CSI thus represents a more reliable and precise model for DFWS.
Web• CSI-RS resource may start at any OFDM symbol of the slot and it usually occupies 1/2/4 OFDM symbols depending upon configured number of ports. • CSI-RS can be periodic, semi-persistent or aperiodic (due to DCI triggering) • For time/frequency tracking, CSI-RS can either be periodic or aperiodic. It is transmitted in bursts of two or ... In NR 5G, the three types of CSI-RS based reference signal measurements, as defined in TS 38.215 Sections 5.1.2 and 5.1.4, includes: CSI-RSRP (CSI reference signal received power): CSI-RSRP is defined as the linear average over the power contributions of the resource elements of the antenna ports, which carry CSI-RS configured for RSRP ...
