A.6.1.2 Test Requirements

A.6.1.2.1 Test 1

The Re-establishment delay T_RE-ESTABLISH to a known cell shall be less than 1.9s.

The rate of correct RRC re-establishments observed during repeated tests shall be at least 90%.

NOTE: The Re-establishment delay in this case can be expressed as

T_RE-ESTABLISH= T_{RRC-RE-ESTABLISH}+ T_{UE-RE-ESTABLISH-REQ-KNOWN}.

where

T_{RRC-RE-ESTABLISH}=160ms+(N₃₁₃-1)*10ms+T₃₁₃

T_{UE-RE-ESTABLISH_REQ-KNOWN}=50ms+T_search + T_SI + T_RA,

N₃₁₃=20

T₃₁₃=0s

T_search=100ms

T_RA= The additional delay caused by the random access procedure. 40 ms is assumed in this test case.

T_SI is the time required for receiving all the relevant system information data according to the reception procedure and the RRC procedure delay of system information blocks defined in 25.331 for a UTRAN cell (ms). 1280 ms is assumed in this test case.

This gives a total of 1820ms, allow 1.9s in the test case.

A.6.1.2.2 Test 2

The Re-establishment delay to an unknown cell shall be less than 4.2s.

The rate of correct RRC re-establishments observed during repeated tests shall be at least 90%.

NOTE: The Re-establishment delay in this case can be expressed as

T_RE-ESTABLISH= T_{RRC-RE-ESTABLISH}+ T_{UE-RE-ESTABLISH-REQ-UNKNOWN}.

where

T_{RRC-RE-ESTABLISH}=160ms+(N₃₁₃-1)*10ms+T₃₁₃

T_{UE-RE-ESTABLISH-REQ-UNKNOWN}=50ms+T_search*NF + T_SI + T_RA,

N₃₁₃=20

T₃₁₃=0s

T_search=800ms

NF is the number of different frequencies in the monitored set. 3 frequencies are assumed in this test case.

T_RA= The additional delay caused by the random access procedure. 40 ms is assumed in this test case.

This gives a total of 4120ms, allow 4.2s in the test case.

The radio conditions in the test shall be sufficient, so that decoding of the TPC commands can be made without errors.

The amount of available user data shall be sufficient to allow uplink transmission at the highest bit rate (UL_TFC8 or UL_TFC9) during the entire test and it shall be ensured that the UE is using UL_TFC8 or UL_TFC9 at the end of T1.

The test shall be performed in the following way:

Before time period T1:

The allowed TFCS according to table A.6.10 shall be signalled to the UE.

During time period T1:

The system simulator shall ensure that the UE output power is commanded to be between 14 to 15 dB below the UE Maximum allowed UL TX power.

During time period T2:

The system simulator shall continously send TPC_cmd=1 to the UE from the beginning of T2 until the end of T2.

NOTE: This will emulate that UL_TFC8 to UL_TFC9 can not be supported beacuse the UE reaches the maximum UL Tx power and still UTRAN is sending power-up commands. The time from the beginning of T2 until the UE blocks (stops using) UL_TFC8 and UL_TFC9 shall be measured.

The test shall be performed in the following way:

Before time period T1:

The allowed TFCS according to table A.6.10a shall be signalled to the UE.

During time period T1:

The system simulator shall ensure that the UE output power is commanded to be between 14 to 15 dB below the UE Maximum allowed UL TX power.

During time period T2:

The system simulator shall continously send TPC_cmd=1 to the UE from the beginning of T2 until the end of T2.

NOTE: This will emulate that UL_TFC28 to UL_TFC29 can not be supported beacuse the UE reaches the maximum UL Tx power and still UTRAN is sending power-up commands. The time from the beginning of T2 until the UE blocks (stops using) UL_TFC28 and UL_TFC29 shall be measured.

A.6.4.2 Test Requirements

A.6.4.2.1 Interactive or Background, PS, UL: 64 kbps

The UE shall have stopped using UL_TFC8 and UL_TFC9 within 140 ms from beginning of time period T2.

The rate of correct tests observed during repeated tests shall be at least 90%.

NOTE: The delay from the begining of T2 can be expressed as:

T_ramp + T_{detect_block} + T_notify + T_modify+ T_{L1_proc} + T_{align_TTI}

where:

T_ramp Margin added for the increase of UE output power to the UE maximum power. A margin of 1 frame (10ms) is used, i.e. 15 TPC commands.

T_{detect_block} The time needed to detect that UL_TFC8 and UL_TFC9 can no longer be supported, i.e. defines the maximum time to detect that the Elimination criterion is fulfilled for UL_TFC8 and UL_TFC9. According to X and Y values of 15 and 30 as defined in Section 6.4.2 and by assuming the maximum misalignment between the frame boundary, where the evaluation of the Elimination criterion is performed and the last slot needed for triggering the Elimination criterion on L1, T_{detect_block} becomes 15 slots +14 slots =19.33 ms.

T_notify Equal to 15 ms, the time allowed for MAC to indicate to higher layers that UL_TFC8 and UL_TFC9 can no longer be supported.

T_modify Equal to MAX(T_{adapt_max},T_TTI) = MAX(0, 40)=40ms

T_{adapt_max} Equals to 0ms for the case without codec.

T_{L1_proc} Equals 15ms.

T_{align_TTI} Align with the longest uplink TTI where the new TFC can be selected. The worst case equals 40ms in this test case.

T_TTI See section 6.4.2. Equals 40 ms in the test case.

This gives a maximum delay of (10 + 19.33 + 15 + 40 + 15 + 40) ms= 139.33 ms from the beginning of T2, allow 140 ms in the test case.

A.6.4.2.2 Interactive or Background, PS, UL: 64 kbps + Conversational / speech, CS, UL: 12.2kbps

The UE shall have stopped using UL_TFC28 and UL_TFC29 within 140 ms from beginning of time period T2.

The rate of correct tests observed during repeated tests shall be at least 90%.

NOTE: The delay from the begining of T2 can be expressed as:

T_ramp + T_{detect_block} + T_notify + T_modify+ T_{L1_proc} + T_{align_TTI}

where:

T_ramp Margin added for the increase of UE output power to the UE maximum power. A margin of 1 frame (10ms) is used, i.e. 15 TPC commands.

T_{detect_block} The time needed to detect that UL_TFC28 and UL_TFC29 can no longer be supported, i.e. defines the maximum time to detect that the Elimination criterion is fulfilled for UL_TFC28 and UL_TFC9. According to X and Y values of 15 and 30 as defined in Section 6.4.2 and by assuming the maximum misalignment between the frame boundary, where the evaluation of the Elimination criterion is performed and the last slot needed for triggering the Elimination criterion on L1, T_{detect_block} becomes 15 slots +14 slots =19.33 ms.

T_notify Equal to 15 ms, the time allowed for MAC to indicate to higher layers that UL_TFC28 and UL_TFC29 can no longer be supported.

T_modify Equal to MAX(T_{adapt_max},T_TTI) = MAX(0, 40)=40ms

T_{adapt_max} Equals to 0ms for the case without codec.

T_{L1_proc} Equals 15ms.

T_{align_TTI} Align with the longest uplink TTI where the new TFC can be selected. The worst case equals 40ms in this test case.

T_TTI See section 6.4.2. Equals 40 ms in the test case.

This gives a maximum delay of (10 + 19.33 + 15 + 40 + 15 + 40) ms= 139.33 ms from the beginning of T2, allow 140 ms in the test case.

The radio conditions in the test shall be sufficient, so that decoding of the TPC commands can be made without errors.

The amount of available user data shall be sufficient to allow E-DCH uplink transmission at the highest possible bit rate with E-DCH TB index 127. It shall also be ensured that sufficient data is made available on the DTCH so that the UE is continuously transmitting on the DPCH.

The test shall be performed in the following way:

Initial conditions:

Call is established with DCH, HSDPA and E-DCH radio bearers. An absolute grant with the value 31 is sent on the E-AGCH to give the UE sufficient grants to make use of the maximum possible data rate.

Before time period T1:

The UE shall be transmitting at its maximum DPCCH power and the UE uplink E-DPCCH shall indicate use of E-TFCI with index 0.

During time period T1:

From the start of T1 the system simulator shall send sufficient consecutive TPC_cmd= -1 to the UE until the DPCCH power is between 0dBm and 1dBm for a power class 3 UE, or between -4dBm and -3dBm for a power class 4 UE. Within 45ms from the start of T1, the UE uplink E-DPCCH shall indicate use of E-TFCI 127, or the E-TFCI which represents the maximum of the UE’s capabilities.

Before time period T2:

The UE P_DPCCH power shall be between 0dBm and 1dBm for a power class 3 UE, or between -4dBm and -3dBm for a power class 4 UE, and the UE uplink E-DPCCH shall indicate either be not transmitted or use of E-TFCI 127, or the E-TFCI which represents the maximum of the UE’s capabilities.

During time period T2:

The system simulator shall continuously send TPC_cmd=1 to the UE from the beginning of T2 until the end of T2. Within 45ms from the start of T2, the UE uplink E-DPCCH shall indicate use of E-TFCI with index 0.

NOTE: During this phase the UE may perform DTX of the E-DPDCH in accordance with [18] clause 5.1.2.6.

Time periods T1 and T2 shall be repeated until the necessary statistical confidence is achieved.

A.6.6.1.1.1 Test Requirements

During time period T1, uplink power control shall be adjusted so that the UE is able to make use of E-TFC index 127, or the maximum of its capabilities if this is lower.

NOTE: The required headroom to support E-TFC 127 can be calculated using the parameters L_ref=1, K_ref=18 and K₁₂₇=20000. This requires {(5006)*3+12}*4=60120 before rate matching/ARQ. This can be transmitted on 2xSF/2 codes, so needs equivalent of 4xSF/4 codes, giving L₁₂₇=4.

Substituting into the equation for β_ed,j,harqfrom 25.214:

gives

β_ed,j,harq= 5 * sqrt (1/4) * sqrt (20000 / 18) = 83.333

For the SF/2 case, the unquantised gain factor _ed,k,j,uq for each of these two codes is according to

_ed,k,j,uq= _ed,k,j,uq=

_ed,k,j,uq= sqrt(2) * 83.333 = 117.85

_ed,k is set such that _ed,k/_c is the largest quantized value of Table 1B.2 in [3] subclause 4.2.1.3, for which the condition _ed,k ≤ _ed,k,j,uq holds.

According to 25.213 Table 1B.2 in subclause 4.2.1.3, the corresponding quantised amplitude ratio has index 25,
A_ed=_ed/_c= 106/15 for each of the two SF/2 E-DPDCH codes.

The E-TFC selection MPR for this case from 25.133 table 6.2 corresponds to case 6, or an E-TFC MPR of 0.5dB.

For a power class 3 UE PMax_j = 23.5dBm = 223.87mW, or for a power class 4 UE, PMax_j = 20.5dBm = 112.20mW

The inequality for support of E-TFC with index 127 is

223.87/P_DPCCH – (1+ (9²/15²) + 2² + 2² ) ≥ 106²/15² + 106²/15²(class 3)

112.20/P_DPCCH – (1+ (9²/15²) + 2² + 2² ) ≥ 106²/15² + 106²/15²(class 4)

This is satisfied if P_DPCCH ≤ (223.87/109.23) = 2.04mW = 3.11dBm for a class 3 UE or P_DPCCH ≤ (112.20/109.23) = 1.03mW = 0.12dBm for a class 4 UE.

From table 6.0A the accuracy of the P_DPCCH estimate used for E-TFC selection in this scenario is ±2dB for power class 3 or ±2.5dB for power class 4. Therefore, for P_DPCCH ≤ 1.11dBm (class 3) or -2.38dBm (class 4), the UE shall be able to support E-TFC index 127. Since power control granularity is 1dB, the UE output power should be maintained so that 0dBm ≤ P_DPCCH≤ 1dBm throughout this phase for a class 3 UE, or so that -4dBm ≤ P_DPCCH≤ -3dBm throughout this phase for a class 4 UE.

NOTE: Test tolerance may need to be added to further reduce the UE DPCCH power further by RAN5, depending on how accurately tester can set and maintain UE DPCCH power.

NOTE: The required time to start using E-TFC index 127 or the maximum of the UEs cababilites at the beginning of T1, and to start using E-TFC with index 0 at the beginning of T2 can be calculated as follows.

Since TPC commands are received error free by the UE, P_DPCCH shall reach the new power level power within 25 slots = 16.666ms.

The UE shall have evaluated and started to use the new restriction criteria with T_s = (Power level change time + P_DPCCH filtering period + E-TFC estimation rate + Maximum time from RGCH reception to E-TFC transmission) from the start of the time period

= 16.66ms + 10ms + 10ms + 7.53ms

= 44.19ms, allow 45ms

The rate of correct tests observed during repeated tests shall be at least 90%.

A.6.6.1.2 2ms TTI E-DCH E-TFC restriction testcase

The test will verify the general requirement on E-TFC restriction and recovery in section 6.4 for a 2ms TTI E-DCH Transport Block Size Table 0 [19].

The test parameters are given in Table A.6.15 below. The test consists of 2 time periods, with a time duration of T1 and T2 respectively.

The radio conditions in the test shall be sufficient, so that decoding of the TPC commands can be made without errors.

The test shall be performed in the following way:

Initial conditions:

Call is established with DCH, HSDPA and E-DCH radio bearers. An absolute grant with the value 31 is sent on the E-AGCH to give the UE sufficient grants to make use of the maximum possible data rate.

Before time period T1:

The UE shall be transmitting at its maximum DPCCH power and the UE uplink E-DPCCH shall indicate use of E-TFCI with index 0.

During time period T1:

From the start of T1 the system simulator shall send sufficient consecutive TPC_cmd= -1 to the UE until the DPCCH power is between 2dBm and 3dBm for a power class 3 UE, or between -1dBm and 0dBm for a power class 4 UE. Within 23ms from the start of T1, the UE uplink E-DPCCH shall indicate use of E-TFCI 127, or the E-TFCI which represents the maximum of the UE’s capabilities.

Before time period T2:

The UE P_DPCCH power shall be between 2dBm and 3dBm for a power class 3 UE, or between -1dBm and 0dBm for a power class 4 UE, and the UE uplink E-DPCCH shall either be not transmitted or indicate use of E-TFCI 127, or the E-TFCI which represents the maximum of the UE’s capabilities.

During time period T2:

The system simulator shall continuously send TPC_cmd=1 to the UE from the beginning of T2 until the end of T2. Within 23ms from the start of T2, the UE uplink E-DPCCH shall indicate use of E-TFCI with index 0.

NOTE: During this phase the UE may perform DTX of the E-DPDCH in accordance with [18] clause 5.1.2.6.

Time periods T1 and T2 shall be repeated until the necessary statistical confidence is achieved.

A.6.6.1.2.1 Test Requirements

During time period T1, uplink power control shall be adjusted so that the UE is able to make use of E-TFC index 127, or the maximum of its capabilities if this is lower.

NOTE: The required headroom to support E-TFC 127 can be calculated using the parameters L_ref=1, K_ref=18 and K₁₂₇=11484. This requires {(3836)*3+12}*3 =34560 bits before rate matching/ARQ. This can be transmitted on 2xSF/2 codes and 2xSF/4 codes, so needs equivalent of 6xSF/4 codes, giving L₁₂₇=6.

Substituting into the equation for β_ed,j,harqfrom 25.214:

gives

βed,j,harq= 5 * sqrt (1/6) * sqrt (11484 / 18) = 51.56

For the SF/2 codes, the unquantised gain factor _ed,k,j,uq for each of these two codes is according to _ed,k,j,uq= _ed,k,j,uq=

ed,k,j,uq= sqrt(2) * 51.56 = 72.91

And for the SF/4 codes, the unquantised gain factor is _ed,k,j,uq =51.56

_ed,k is set such that _ed,k/_c is the largest quantized value of Table 1B.2 in [3] subclause 4.2.1.3, for which the condition _ed,k ≤ _ed,k,j,uq holds.

According to 25.213 Table 1B.2 in subclause 4.2.1.3, the corresponding quantised amplitude ratio are A_ed=_ed/_c= 67/15 for each of the two SF/2 E-DPDCH codes and A_ed=_ed/_c= 47/15 for each of the two SF/4 codes

The E-TFC selection MPR for this case from 25.133 table 6.2 is 0.0dB.

For a power class 3 UE PMax_j = 24dBm = 251.2mW, or for a power class 4 UE, PMax_j = 21dBm = 125.9mW

The inequality for support of E-TFC with index 127 is

251.2/P_DPCCH – (1+ (9²/15²) + 2² + 2² ) ≥ 47²/15² + 47²/15²+67²/15² + 67²/15² (class 3)

125.9/P_DPCCH – (1+ (9²/15²) + 2² + 2² ) ≥ 47²/15² + 47²/15²+67²/15² + 67²/15²(class 4)

This is satisfied if P_DPCCH ≤ (251.2/68.9) = 3.64mW = 5.61dBm for a class 3 UE or P_DPCCH ≤ (125.9/68.9) = 1.82mW = 2.61dBm for a class 4 UE.

From table 6.0A the accuracy of the Pdpcch estimate used for E-TFC selection in this scenario is ±2dB for power class 3 or ±2.5dB for power class 4. Therefore, for P_DPCCH ≤ 3.61dBm (class 3) or 0.11dBm (class 4), the UE shall be able to support E-TFC index 127. Since power control granularity is 1dB, the UE output power should be maintained so that 2dBm ≤ P_DPCCH≤ 3dBm throughout this phase for a class 3 UE, or so that -1dBm ≤ P_DPCCH≤ 0dBm throughout this phase for a class 4 UE.

NOTE: Test tolerance may need to be added to further reduce the UE DPCCH power further by RAN5, depending on how accurately tester can set and maintain UE DPCCH power.

Since TPC commands are received error free by the UE, P_DPCCH shall reach the new power level power within 20 slots = 13.33ms.

The UE shall have evaluated and started to use the new restriction criteria with T_s = (Power level change time + Pdpcch filtering period + E-TFC estimation rate + Maximum time from RGCH reception to E-TFC transmission) from the start of the time period

= 13.33ms + 2ms + 2ms + 5.53ms

= 22.86ms, allow 23ms

The rate of correct tests observed during repeated tests shall be at least 90%.
