A.8.5A CSG Proximity Indication Testing Case for UTRAN FDD – FDD Inter frequency

25.1333GPPRelease 17Requirements for support of radio resource management (FDD)TS

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

Note : The test case in this section forms the basis for a signalling test for CSG proximity detection.

A.8.5A.1 Test Purpose and Environment

The purpose of this test is to verify the UE has implemented properly the feature for indicating that the UE is entering or leaving the proximity of one or more CSG member cells based on proximity detection with an autonomous search function as defined by the requirements in Section 6.7.

The test case consists of three successive segments: Test Preparation, Negative Test, and Positive Test. The test scenario comprises of three UTRAN FDD cells on different carriers. Cell 1 represents the serving cell in the proximity of the CSG cell, Cell 2 the CSG cell and Cell 3 the serving cell not in the proximity of the CSG cell. The description of the test procedure is shown in Table A.8.5A-1. The general test parameters and cell specific test parameters are presented in Table A.8.5A-2 and Table A.8.5A-3 respectively.

Table A.8.5A-1: Description of the test procedures

Parameter	Cell Status	Comment
Test Preparation
Initial Condition	Cell 1 is active	Clean up the UE memory to be free from previously stored cell information for proximity detection. Turn on the UE and allow sufficient time for the UE to reselect to Cell 1.
Time duration T1	Cell 1 and Cell 2 are active	Turn on Cell 2 at the start of T1. Perform manual CSG selection towards Cell 2. The UE is expected to store necessary information for later proximity detection.
End condition		Turn off the UE. Turn off Cell 1 and Cell 2.
Negative Test
Initial Condition	Cell 3 is active	Turn on Cell 3. Turn on the UE and set up the UE in connected mode with Cell 3
Time duration T2	Cell 3 is active	Configure the UE with proximity indication control by sending the Measurement Control message to enable CSG Proximity detection at the start of T2. The UE is not expected to report “entering” proximity in the negative test.
End condition		Turn off the UE. Turn off Cell 3.
Positive Test
Initial Condition	Cell 1 is active	Turn on Cell 1. Turn on the UE and set up the UE in connected mode with Cell 1
Time duration T3	Cell 1 and Cell 2 are active	Turn on Cell 2 at the start of T3. Configure the UE with proximity indication control by sending the Measurement Control message to enable CSG Proximity at the start of T3. The UE is expected to report “entering” proximity before end of T3.
Time duration T4	Cell 1 is active and Cell 3 are active	Turn off Cell 2 and turn on Cell 3 at the start of T4. Hand the UE over^{Note 1}from Cell 1 to Cell 3 . (Note: The UE may report “leaving” proximity in T4. In this case, there is no need to proceed to the next step.).
Time duration T5	Cell 3 are active	Turn off Cell 1 at the start of T5. The procedures in T4 and T5 together simulate the situation that UE leaves the proximity of the CSG cell. The UE is expected to report “leaving” proximity before end of T5..
End condition		Turn off the UE. Turn off Cell 1 and Cell 3.
Note 1: The handover from Cell 1 to Cell 3 must preserve the proximity configuration (i.e. must involve neither SR-VCC handover, nor SRNS relocation, as described in [16])

Parameter		Unit	Value	Comment
DCH parameters			DL and UL Reference Measurement Channel 12.2 kbps	As specified in TS 25.101 section A.3.1 and A.2.1
Power Control			On
Target quality value on DTCH		BLER	0.001
Compressed mode			A.22 set 1	As specified in TS 25.101 section A.5.
Initial conditions	Active cell		Cell 1
Initial conditions	Neighbour cell		Cell 2
Final conditions	Active cell		Cell 1	Handover to cell 2 is not requested
Threshold non used frequency		dB	-18	Absolute Ec/I0 threshold for event 2C
Hysteresis		dB	0
W non-used frequency			1	Applicable for event 2C
Time to Trigger		Ms	0
Filter coefficient			0
SIB3_REP		Frames	32	Applicable for cell 2 SIB3 scheduling
SIB3 SEG_COUNT			1	Applicable for cell 2 SIB3 scheduling
CSG id (of cell 2)			Set to any non-empty value
CSG Indicator (of cell 2)			Set to TRUE
UE whitelist			Include Cell 2
Monitored cell list size			24 on channel 1 16 on channel 2	Measurement control information is sent before the compressed mode pattern starts.
Time duration T1		s	[10]	Defined to give enough time for the UE to complete the registration to Cell 2.
Time duration T2		s	[360]	Defined to be longer enough to see whether the UE will report enter “proximity” indication.
Time duration T3^{Note 1}		s	[<=360]	The time duration for a UE to report enters “proximity” when the UE is near a CSG cell.
Time duration T4^{Note 1}		s	[<=360]	The time duration for a UE to be handed over to Cell 3.
Time duration T5 ^{Note 1}		s	[<=360]	The time duration for a UE to report leaving “proximity” when the UE is no longer near a CSG cell.
Note 1: The maximum allowed time duration for the UE to decide either entering or leaving “proximity” is 360s. To reduce test time, T3 may end once UE reports entering “proximity”, T4 may end once the UE is handed over to Cell 3 and T5 may end once UE reports leaving “proximity”. Note 2: The test case assumes an environment where CSG proximity detection results not being impact by non-3GPP signals, such as GPS and WiFi. When the test case is being executed, the UE may ignore any radio signals which are not provided by the test setup which it would otherwise use in proximity estimation.
