provides the conditions for the selection of a new 5G cell of the same frequency (intra-frequency) as that of the server cell. Q-OffsetRange: this parameter provides the offset value to apply for the selection of a cell or a beam. SSB-MTC: this parameter provides the SMTC (SSB-based Measurement Timing Configuration) corresponding to the occasions of measurement of the SSB by the mobile. SS-RSSI-Measurement: this parameter provides the configuration of the RSSI (NR carrier Received Signal Strength Indicator) measurement performed on the reference signals. SSB-ToMeasure. this parameter provides the set of SSBs to be measured during the SMTC time. In the absence of this parameter, all SSBs must be measured. 244 NG-RAN and 5G-NR 9.1.4. SIB3 message The SIB3 message provides the information which allows the mobile to select an intra-frequency neighboring cell. The SIB3 message contains the following parameters: SystemInformationBlockType3 intraFreqNeighCellList intraFreqBlackCellList The two parameters are optional, the mobile having the ability to select a new intra-frequency cell without this information. intraFreqNeighCellList: this parameter provides a list of neighboring PSCells identified by their PCI (Physical layer Cell Identity) and the minimum RSRP power level expected for the main cell and the additional SUL (Supplementary UpLink). intraFreqBlackCellList: this setting provides a list of forbidden neighbor cells (up to 16 forbidden cell ranges). 9.1.5. SIB4 message The SIB4 message provides information relating to neighboring 5G cells of different frequencies (inter-frequency) from that of the server cell and the re-direction criteria. The SIB4 message contains the following parameters: SystemInformationBlockType4 interFreqCarrierFreqList interFreqCarrierFreqlList: this parameter provides the ARFCN frequencies of the downlink carriers and the common information relating to the neighboring inter-frequency cells (like the information provided by SIB2: cell re-selection, SMTC, etc.). 9.1.6. SIB5 message The SIB
