– Test Tolerance

6.2.5B.1 Test purpose

To verify the UE does not exceed the minimum between the P_EMAX maximum allowed UL TX Power for UL-MIMO signalled by the E-UTRAN and the P_UMAX maximum UE power for the UE power class.

6.2.5B.2 Test applicability

This test applies to all types of E-UTRA UE release 10 and forward that support UL- MIMO.

6.2.5B.3 Minimum conformance requirements

For UE with multiple transmit antenna connectors, the transmitted power is configured per each UE.

The definitions of configured maximum output power P_CMAX,_c, the lower bound P_{CMAX_L,}_c, and the higher bound P_{CMAX_H,}_c specified in Section 6.2.5 shall apply to UE with multiple transmit antenna connectors, where

– P_PowerClass and T_C,_c are specified in Section 6.2.2B;

– MPR_c is specified in Section 6.2.3B;

– A-MPR_c is specified in Section 6.2.4B.

The measured configured maximum output power P_UMAX,_c for serving cell c shall be within the following bounds:

P_{CMAX_L,}_c– MAX{T_L, T_LOW(P_{CMAX_L,}_c) } ≤ P_UMAX,_c≤ P_{CMAX_H,}_c+ T_HIGH(P_{CMAX_H,}_c)

where T_LOW(P_{CMAX_L,}_c) and T_HIGH(P_{CMAX_H,}_c) are defined as the tolerance and applies to P_{CMAX_L,}_c and P_{CMAX_H,}_c separately, while T_L is the absolute value of the lower tolerance in Table 6.2.2B.3-1 for the applicable operating band.

For UE with two transmit antenna connectors, the tolerance is specified in Table 6.2.5B.3-1 with UL-MIMO configurations specified in Table 6.2.2B.3-2.

Table 6.2.5B.3-1: P_CMAX,_c tolerance in closed-loop spatial multiplexing scheme

P_CMAX,_c(dBm)	Tolerance T_LOW(P_{CMAX_L,}_c) (dB)	Tolerance T_HIGH(P_{CMAX_H,}_c) (dB)
P_CMAX,_c =23	3.0	2.0
[22] ≤ P_CMAX,_c < [23]	[5.0]	[2.0]
[21] ≤ P_CMAX,_c < [22]	[5.0]	[3.0]
[20] ≤ P_CMAX,_c < [21]	[6.0]	[4.0]
[16] ≤ P_CMAX,_c < [20]	[5.0]
[11] ≤ P_CMAX,_c < [16]	[6.0]
[-40] ≤ P_CMAX,_c < [11]	[7.0]

6.2.5B.4 Test description

6.2.5B.4.1 Initial conditions

Initial conditions are a set of test configurations the UE needs to be tested in and the steps for the SS to take with the UE to reach the correct measurement state.

The initial test configurations consist of environmental conditions, test frequencies, and channel bandwidths based on E-UTRA operating bands specified in table 5.4.2.1-1. All of these configurations shall be tested with applicable test parameters for each channel bandwidth, and are shown in table 6.2.5B.4.1-1. The details of the uplink reference measurement channels (RMCs) are specified in Annex A.2. Configurations of PDSCH and PDCCH before measurement are specified in Annex C.2.

Table 6.2.5B.4.1-1: Test Configuration Table

Initial Conditions
Test Environment as specified in TS 36.508 [7] subclause 4.1		Normal, TL/VL, TL/VH, TH/VL, TH/VH
Test Frequencies as specified in TS 36.508 [7] subclause 4.3.1		Mid range

Note 1: Test Channel Bandwidths are checked separately for each E-UTRA band, the applicable channel bandwidths are specified in Table 5.4.2.1-1. Note 2: For the uplink RB allocation the RB_start shall be RB #0.

1. Connect the SS to the UE antenna connectors as shown in TS 36.508 [7] Annex A, in Figure A.28.

2. The parameter settings for the cell are set up according to TS 36.508 [7] subclause 4.4.3.

3. Downlink signals are initially set up according to Annex C.0, C.1, and C.3.0, and uplink signals according to Annex H.1 and H.3.0.

4. The UL Reference Measurement channel is set according to Table 6.2.5B.4.1-1

5. Propagation conditions are set according to Annex B.0.

6. Ensure the UE is in State 3A-RF according to TS 36.508 [7] clause 5.2A.2. Message contents are defined in clause 6.2.5B.4.3.

6.2.5B.4.2 Test procedure

1. SS sends uplink scheduling information for each UL HARQ process via PDCCH DCI format 4 for C_RNTI to schedule the UL RMC according to Table 6.2.5B.4.1-1. Since the UE has no payload and no loopback data to send the UE sends uplink MAC padding bits on the UL RMC.

2. Send transmit uplink power control "up" commands in every uplink scheduling information to the UE; allow at least 200ms for the UE to reach the P_umax level of the test point.

3. Measure the sum mean power of the UE at each UE antenna connector in the associated measurement bandwidth for each test point in table 6.2.5B.5-1 according to the test configuration from Table 6.2.5B.4.1-1. The period of measurement shall be at least continuous duration of one sub-frame (1ms). For TDD slots with transient periods are not under test.

Note: In addition note 2 in Table 6.2.2B.3-1 shall apply to the tolerances.

For the UE which supports inter-band carrier aggregation configurations with uplink assigned to one E-UTRA band the ΔT_IB,c in Tables 6.2.5.3-2, 6.2.5.3-3 and 6.2.5.3-4 shall be applied for applicable bands.

In case the UE supports more than one of the above inter-band carrier aggregation configurations and an E-UTRA operating band belongs to more than one inter-band carrier aggregation configurations then:

– When the E-UTRA operating band frequency range is ≤ 1GHz, the applicable additional tolerance shall be the average of the tolerances in Table 6.2.5.3-2, truncated to one decimal place for that operating band among the supported CA configurations. In case there is a harmonic relation between low band UL and high band DL, then the maximum tolerance among the different supported carrier aggregation configurations involving such band shall be applied

– When the E-UTRA operating band frequency range is >1GHz, the applicable additional tolerance shall be the maximum tolerance in Table 6.2.5.3-2 that applies for that operating band among the supported CA configurations.
