8.2.9 Common Measurement Reporting

25.4333GPPRelease 17TSUTRAN Iub interface Node B Application Part (NBAP) signalling

Tools: ARFCN - Frequency Conversion for 5G NR/LTE/UMTS/GSM

8.2.9.1 General

This procedure is used by the Node B to report the result of measurements requested by the CRNC with the Common Measurement Initiation procedure.

8.2.9.2 Successful Operation

Figure 13: Common Measurement Reporting procedure, Successful Operation

If the requested measurement reporting criteria are met, the Node B shall initiate the Common Measurement Reporting procedure. The COMMON MEASUREMENT REPORT message shall use the Node B Control Port.

The Measurement ID IE shall be set to the Measurement ID provided by the CRNC when initiating the measurement with the Common Measurement Initiation procedure.

[1.28Mcps TDD –If Time Slot LCR IE is not present in the COMMON MEASUREMENT INITIATION REQUEST message, the measurement results of all the available time slots in the frequency should be included in the COMMON MEASUREMENT INITIATION REPORT message.]

[1.28Mcps TDD – If UARFCN IE is not present in the COMMON MEASUREMENT INITIATION REQUEST message, the measurement results of all the frequencies in the cell should be included in the COMMON MEASUREMENT INITIATION REPORT message.]

[1.28Mcps TDD – If neither UARFCN IE nor Time Slot LCR IE is present in the COMMON MEASUREMENT INITIATION REQUEST message, the measurement results of all available time slots in all frequencies should be included in the COMMON MEASUREMENT INITIATION REPORT message.]

[1.28Mcps TDD – If Additional Time Slot LCR IE is present in the COMMON MEASUREMENT INITIATION REQUEST message, the measurement results of the additional time slot (s) should be included in the COMMON MEASUREMENT INITIATION REPORT message.]

If the achieved measurement accuracy does not fulfil the given accuracy requirement (see ref. TS 25.133 [22] and TS 25.123 [23]) or the measurement is temporarily not available in case Measurement Recovery Behavior is supported, the Common Measurement Value Information IE shall indicate Measurement not Available. If the Node B was configured to perform the Measurement Recovery Behavior, the Node B shall indicate Measurement Available to the CRNC when the achieved measurement accuracy again fulfils the given accuracy requirement (see ref. TS 25.133 [22] and TS 25.123 [23]) and include the Measurement Recovery Report Indicator IE in the COMMON MEASUREMENT REPORT message if the requested measurement reporting criteria are not met.

For measurements included in the Successful Neighbouring Cell SFN-SFN Observed Time Difference Measurement Information IE, the Node B shall include the SFN-SFN Quality IE and the SFN-SFN Drift Rate Quality IE if available.

If the Common Measurement Type provided by RNC when initiating the measurement with the Common Measurement Initiation procedure was "UTRAN GPS Timing of Cell Frames for UE Positioning", then the Node B shall include in the T_UTRAN-GPS Measurement Value Information IE the T_UTRAN-GPS Quality IE and the T_UTRAN-GPS Drift Rate Quality IE, if available.

If the Common Measurement Type provided by RNC when initiating the measurement with the Common Measurement Initiation procedure was "UTRAN GANSS Timing of Cell Frames for UE Positioning", then the Node B shall include in the T_UTRAN-GANSS Measurement Value Information IE the T_UTRAN-GANSS Quality IE and the T_UTRAN-GANSS Drift Rate Quality IE, if available.

[FDD and 1.28Mcps TDD – For Received Total Wide Band Power for Cell Portion, Transmitted Carrier Power for Cell Portion, [FDD -Transmitted carrier power of all codes not used for HS-PDSCH, HS-SCCH, E-AGCH, E-RGCH or E-HICH transmission for Cell Portion][1.28Mcps TDD – Transmitted carrier power of all codes not used for HS-PDSCH, HS-SCCH, E-AGCH or E-HICH transmission for Cell Portion], HS-DSCH Required Power for Cell Portion, HS-DSCH Provided Bit Rate for Cell Portion[1.28Mcps TDD – , "E-DCH Provided Bit Rate for Cell Portion", "UpPCH interference for Cell Portion"], [FDD – Received Scheduled E-DCH Power Share for Cell Portion][1.28Mcps TDD – UL Timeslot ISCP for Cell Portion] measurements, all the available measurement results for each cell portion shall be included in the COMMON MEASUREMENT REPORT message.]

If the Common Measurement Object Type provided by RNC when initiating the measurement with the Common Measurement Initiation procedure was "Cell" or "RACH", then the Node B, if supported, shall include the C-ID IE in the COMMON MEASUREMENT REPORT message.
