6.6.1EA.4 Test description

6.6.1E.4A.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 clause 5.2E. All of these configurations shall be tested with applicable test parameters for each channel bandwidth, and are shown in table 6.6.1EA.4.1-1. The details of the uplink reference measurement channels (RMCs) are specified in Annexes A.2. Configurations of PDSCH and MPDCCH before measurement are specified in Annex C.2.

Note 1: Denote where in the channel bandwidth the narrowband shall be placed. Narrowband and narrowband index are defined in TS 36.211, 5.2.4.

1. Connect the SS to the UE antenna connectors as shown in TS 36.508 [7] Annex A 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 4.4.3.

3. Downlink signals are initially set up according to Annex C0, C.1, and C.3.0, and uplink signals according to Annex H.1 and H.3.0.

4. The UL Reference Measurement channels are set according to Table 6.6.1EA.4.1-1.

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

6. Ensure the UE is in State 3A-RF-CE according to TS 36.508 [7] clause 5.2A.2AA. Message contents are defined in clause 6.6.1EA.4.3.

6.6.1EA.4.2 Test procedure

1. The SS sends uplink scheduling information for each UL HARQ process via MPDCCH DCI format 6-0A for C_RNTI to schedule the UL RMC according to Table 6.6.1EA.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 power control "up" commands to the UE until the UE transmits at PUMAX level.

3. Measure the power spectrum distribution within two times or more range over the requirement for Occupied Bandwidth specification centring on the current carrier frequency. The characteristic of the filter shall be approximately Gaussian (typical spectrum analyzer filter). Other methods to measure the power spectrum distribution are allowed. The measuring duration is one active uplink subframe. For TDD slots with transient periods are not under test For HD-FDD slots with transient periods and Half-duplex guard subframe are not under test.

4. Calculate the total power within the range of all frequencies measured in ‘3)’ and save this value as "Total Power".

5. Sum up the power upward from the lower boundary of the measured frequency range in ‘3)’ and seek the limit frequency point by which this sum becomes 0,5 % of "Total Power" and save this point as "Lower Frequency".

6. Sum up the power downward from the upper boundary of the measured frequency range in ‘3)’ and seek the limit frequency point by which this sum becomes 0,5 % of "Total Power" and save this point as "Upper Frequency".

7. Calculate the difference ("Upper Frequency" "Lower Frequency" = "Occupied Bandwidth") between two limit frequencies obtained in ‘5)’ and ‘6)’.

6.6.1EA.4.3 Message contents

Message contents are according to TS 36.508 [7] subclause 4.6 with the condition CEModeA.

6.6.1EA.5 Test requirement

The measured Occupied Bandwidth shall not exceed values in Table 6.6.1EA.5-1.
