6.2.3_s UE Maximum Power Reduction (MPR) for subslot/slot TTI
36.521-13GPPEvolved Universal Terrestrial Radio Access (E-UTRA)Part 1: Conformance testingRadio transmission and receptionRelease 17TSUser Equipment (UE) conformance specification
6.2.3_s.1 Test purpose
The number of RB identified in Table 6.2.3_s.3-1 is based on meeting the requirements for adjacent channel leakage ratio and the maximum power reduction (MPR) due to Cubic Metric (CM).
Simple scaling can be used to derive the requirement for other bandwidth based on the previously agreed value for 5MHz channel bandwidth.
6.2.3_s.2 Test applicability
The requirements of this test apply in test cases 6.6.2.3_s Adjacent Channel Leakage power Ratio to all types of E-UTRA Power Class 3 UE release 15 and forward that support subslot/slot TTI.
NOTE: As a result TC 6.2.3_s has not been included in the test case applicability Table 4.1-1, TS 36.521-2. This does not preclude the test from being used for R&D or other purposes if deemed useful.
6.2.3_s.3 Minimum conformance requirements
For UE Power Class 3, the allowed Maximum Power Reduction (MPR) for the maximum output power in Table 6.2.2_s.3-1 due to higher order modulation and transmit bandwidth configuration (resource blocks) is specified in Table 6.2.3_s.3-1.

For PRACH, PUCCH and SRS transmissions, the allowed MPR is according to that specified for PUSCH QPSK modulation for the corresponding transmission bandwidth.
For each TTI pattern the MPR shall be evaluated per Teval period as specified in table 6.2.3_s.3-2 and given by the maximum value taken over the transmission(s) within that period; the maximum MPR over TREF is then applied for TREF.

For the UE maximum output power modified by MPR, the power limits specified in subclause 6.2.5 apply.

6.2.3_s.4 Test description
6.2.3_s.4.1 Initial condition
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 6.2.3_s.4.1-1. The details of the uplink reference measurement channels (RMCs) are specified in Annexe A.2. Configurations of PDSCH and PDCCH before measurement are specified in Annex C.2.

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: The RBstart of partial RB allocation shall be RB#0 and RB# (max + 1 – RB allocation) of the channel bandwidth. Note 3: Applies only for UE-Categories ≥2. |

1. Connect the SS to the UE antenna connectors as shown in TS 36.508 [7] Annex A Figure A.3.
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 6.2.3_s.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 6.2.3_s.4.3.
6.2.3_s.4.2 Test procedure
1. SS sends uplink scheduling information for each UL HARQ process via SPDCCH DCI format 7-0A for C_RNTI to schedule the UL RMC according to Table 6.2.3_s.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 continuously uplink power control "up" commands in the uplink scheduling information to the UE to ensure that the UE transmits at PUMAX level.
3. Measure the mean power of the UE in the channel bandwidth of the radio access mode. The period of measurement shall be at least the continuous duration of 7 OS (0.5ms) for slot TTI and 2/3 OS for subslot TTI. For TDD slots with transient periods are not under test.
