36.521-13GPPEvolved Universal Terrestrial Radio Access (E-UTRA)Part 1: Conformance testingRadio transmission and receptionRelease 17TSUser Equipment (UE) conformance specification
6.2.5F.1 Test purpose
To verify the UE does not exceed the minimum between the PEMAX maximum allowed UL TX Power signalled by the E-UTRAN and the PUMAX maximum UE power for the UE power class.
6.2.5F.2 Test applicability
This test case applies to all types of NB-IoT FDD UE release 13 and forward of category NB1.
This test case applies to all types of NB-IoT FDD UE release 14 and forward of category NB2.
This test case applies to all types of NB-IoT TDD UE release 15 and forward of category NB1 and NB2.
6.2.5F.3 Minimum conformance requirements
For each slot i the NB IoT UE is allowed to set its configured maximum output power PCMAX,c. The configured maximum output power PCMAX,c is set within the following bounds:
PCMAX_L,c ≤ PCMAX,c ≤ PCMAX_H,c
Where
– PCMAX_L,c = MIN { PEMAX,c , PPowerClass – MPRc – A-MPRc}
– PCMAX_H,c = MIN { PEMAX,c, PPowerClass}
– PEMAX,c is the value given to IE P-Max, defined in [7]
– PPowerClass is the maximum category NB1 and NB2 UE power specified in Table 6.2.2F.3-1 without taking into account the associated tolerance
– MPRc is specified in subclause 6.2.3F
A-MPRc = 0dB unless otherwise stated.
The measurement period for PUMAX,c is at least one sub-frame (1ms) for 15 KHz channel spacing, and at least a 2ms slot (excluding the 2304Ts gap when UE is not transmitting) respectively for the 3.75 KHz channel spacing. The measured maximum output power PUMAX,c shall be within the following bounds:
PCMAX_L,c – T(PCMAX_L,c) ≤ PUMAX,c ≤ PCMAX_H,c + T(PCMAX_H,c)
Where T(PCMAX) is defined by the tolerance table below and applies to PCMAX_L,c and PCMAX_H,c separately.

6.2.5F.4 Test description
6.2.5F.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 and test frequencies based on the subset of E-UTRA operating bands defined for NB-IoT in clause 5.2F. All of these configurations shall be tested with applicable test parameters for each channel bandwidth, and are shown in table 6.2.5F.4.1-1. The details of the uplink reference measurement channels (RMCs) are specified in A.2.4. Configurations of NPDSCH and NPDCCH before measurement are specified in Annex C.2.

1. Connect the SS to the UE antenna connectors as shown in TS 36.508 [7] Annex A, in Figure A.3 using only main UE Tx/Rx antenna.
2. The parameter settings for the cell are set up according to TS 36.508 [7] subclause 8.1.4.3.
3. Downlink signals are initially set up according to Annex C, and uplink signals according to Annex H.
4. The UL Reference Measurement channel is set according to Table 6.2.5F.4.1-1
5. Propagation conditions are set according to Annex B.0.
6. Ensure the UE is in State 2A-NB with CP CIoT Optimisation according to TS 36.508 [7] clause 8.1.5. Message contents are defined in clause 6.2.5F.4.3.
6.2.5F.4.2 Test procedure
1. SS sends uplink scheduling information for UL HARQ process via NPDCCH DCI format N0 for C_RNTI to schedule the UL RMC according to Table 6.2.5F.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. Configure UE to transmit NPUSCH with the Pumax level of each test points.
3. Measure the mean power of the UE in the channel bandwidth for each test point in table 6.2.5F.5-1 according to the test configuration from Table 6.2.5F.4.1-1. The period of measurement shall be at least continuous duration of one sub-frame (1ms) for 15 KHz channel spacing, and at least a 2ms slot (excluding the 2304Ts gap when UE is not transmitting) respectively for the 3.75 KHz channel spacing. For TDD slots with transient periods are not under test.
