6.3.4F.1 General ON/OFF time mask for category NB1 and NB2

6.3.4F.1.1 Test purpose

To verify that the general ON/OFF time mask meets the requirements given in 6.3.4F.1.5.

The time mask for transmit ON/OFF defines the ramping time allowed for the UE between transmit OFF power and transmit ON power.

Transmission of the wrong power increases interference to other channels, or increases transmission errors in the uplink channel.

6.3.4F.1.2 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.

6.3.4F.1.3 Minimum conformance requirement

E-UTRA general ON/OFF time mask in subclause 6.3.4.1 applies for category NB1 and NB2 UE with an exception that for 3.75kHz sub-carrier spacing the transmit OFF power is defined as mean power in one slot (2ms) and for 15kHz sub-carrier spacing the transmit OFF power is defined as mean power in one sub-frame (1ms), excluding any transient periods. The ON power is defined as the mean power over one RU excluding any transient periods.

The normative reference for this requirement is TS 36.101 [2] clause 6.3.4F.1.

6.3.4F.1.4 Test description

6.3.4F.1.4.1 Initial conditions

Initial conditions are 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 6.3.4F.1.4.1-1. The details of the uplink reference measurement channel (RMCs) are specified in Annex A.2. Configurations of NPDSCH and NPDCCH before measurement are specified in Annex C.2.

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.0, C.1 and C.3.0, and uplink signals according to Annex H.1.1 and H.4.0.

4. The UL Reference Measurement channel is set according to Table 6.3.4F.1.4.1-1.

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 6.3.4F.1.4.3.

6.3.4F.1.4.2 Test procedure

1. SS sends uplink scheduling information via NPDCCH DCI format N0 for C_RNTI to schedule the UL RMC according to Table 6.3.4F.1.4.1-1. Since the UE has no payload and no loopback data to send the UE sends uplink MAC padding bits on the UL RMC. (UE should be already transmitting PUMAX after Initial Conditions setting)

2. For HD-FDD & TDD: Measure the UE transmission OFF power as the mean power in one sub-frame (1ms) prior to the NPUSCH RU, excluding a transient period of 20 µs at the beginning of the sub-frame.

3. Measure the output power of the UE NPUSCH transmission as the mean power in one RU, excluding a transient period of 20 µs at the beginning of the RU.

4. Measure the UE transmission OFF power power as the mean power in one sub-frame (1ms) following the NPUSCH RU, excluding a transient period of 20 µs at the beginning of the sub-frame.

Editor’s note: The detail measurement of TDD configuration need further study.

6.3.4F.2.1 Test purpose
