Question: In 5G NR (New Radio) measurements, what part of a symbol is excluded when determining the power per resource element for CSI-RSRP (Channel State Information - Reference Signal Received Power)?
Option 1: The entire symbol, to account for interference
Option 2: Only the data portion, not affecting the outcome
Option 3: The Cyclic Prefix (CP), to ensure measurement accuracy
Option 4: Both the CP and the guard bands, for comprehensive measurement
Explanation: When calculating the power per resource element for CSI-RSRP in 5G NR, the energy received during the useful part of the symbol is considered, explicitly excluding the Cyclic Prefix (CP), to ensure only meaningful data transmission parts contribute to the power measurement, enhancing CSI-RSRP determination accuracy.
