4.13; otherwise, if measurement gap is not used, NR_carrier_RSSI is measured over OFDM symbols within SMTC window duration and, if measurement gap is used, NR_carrier_RSSI is measured over OFDM symbols cor- responding to overlapped time span between SMTC window duration and minimum mea- surement time within the measurement gap [10]. If higher layers indicate certain SS/PBCH blocks for performing SS-RSRQ measurements, then SS-RSRP is measured only over the indicated set of SS/PBCH block(s). For frequency range 1, the reference point for the SS- RSRQ is the antenna connector of the UE. For frequency range 2, NR_carrier_RSSI is measured based on the combined signal from antenna elements corresponding to a given receiver branch, where the combining function for NR_carrier_RSSI is the same as the one used for SS-RSRP measurements. For frequency range 1 and 2, if receiver diversity is used by the UE, the reported SS-RSRQ value must not be lower than the corresponding SS-RSRQ of any of the individual receiver branches [10]. CSI-Reference Signal Received Power (CSI-RSRP) is defined as the linear average over the power contributions (in Watts) of the resource elements that carry CSI-RSs config- ured for RSRP measurements within the measurement frequency region in the prede- fined CSI-RS occasions. For CSI-RSRP calculation, the CSI-RSs transmitted on antenna port 3000 or antenna ports 3000, 3001 are used. For frequency range 1, the reference point for the CSI-RSRP is the antenna connector of the UE. For frequency range 2; 508 Chapter 4 however, the CSI-RSRP is measured based on the combined signal from antenna ele- ments corresponding to a given receiver branch. For frequency ranges 1 and 2, if receive diversity is used by the UE, the reported CSI-RSRP value must not be lower than the corresponding CSI-RSRP of any of the individual receiver branches [10]. CSI-Reference Signal Received Quality (CSI-RSRQ) is defined as the ratio of NRB X CSI_RSRP/CSI_RSSI, where NRB denotes the number of resource blocks used in the CSI-RSSI
