36.521-13GPPEvolved Universal Terrestrial Radio Access (E-UTRA)Part 1: Conformance testingRadio transmission and receptionRelease 17TSUser Equipment (UE) conformance specification
6.2.3D.0 Minimum conformance requirements
For UE Power Class 1, 2 and 3, this subclause specifies the allowed Maximum Power Reduction (MPR) power for ProSe physical signals due to higher order modulation and transmit bandwidth configuration (resource blocks).
The allowed MPR for the maximum output power for ProSe physical signal PSSS shall be as be as specified in subclause 6.2.3 for PUSCH QPSK modulation for the corresponding transmission bandwidth.
The allowed MPR for the maximum output power for ProSe physical signal SSSS is specified in Table 6.2.3D.0-1.
For a power class 2 capable UE operating on Band 41, the corresponding requirements for a power class 3 UE apply when an IE P-max as defined in [5] of 23 dBm or lower is indicated in the cell or if the TDD frame configuration is 0 or 6.

6.2.3D.1 Maximum Power Reduction (MPR) for ProSe Discovery
Editor’s note: This test case is not complete. Following aspects are either missing or not yet determined:
– ProSe UE authentication is not handled in the test case and is still under investigation.
– Message exceptions content needs further investigation (some values still TBD).
– Test system uncertainties and test tolerances.
6.2.3D.1.1 Test purpose
To verify that the error of the UE maximum output power does not exceed the range prescribed by the specific maximum output power with MPR and tolerance when operating in ProSe Discovery mode.
An excess maximum output power has the possibility to interfere to other channels or other systems. A small maximum output power decreases the coverage area.
6.2.3D.1.2 Test applicability
This test case applies to all types of E-UTRA UE release 12 and forward which supports ProSe Direct Discovery and SLSS transmission and reception.
6.2.3D.1.3 Minimum conformance requirements
The minimum conformance requirements are defined in clause 6.2.3D.0.
6.2.3D.1.4 Test description
6.2.3D.1.4.1 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 6.2.3D.1.4.1-1. The details of the uplink reference measurement channels (RMCs) are specified in Annexes A.2. Configurations of PDSCH and PDCCH before measurement are specified in Annex C.2.

Note 1: The above tolerances are applicable for UE(s) that support up to 4 E-UTRA operating bands. For UE(s) that support 5 or more E-UTRA bands the maximum output power is expected to decrease with each additional band and is FFS Note 2: For transmission bandwidths (Figure 5.4.2-1, Table 5.4.4-1) confined within FUL_low and FUL_low + 4 MHz or FUL_high – 4 MHz and FUL_high, the maximum output power requirement is relaxed by reducing the lower tolerance limit by 1.5 dB Note 3: PPowerClass is the maximum UE power specified without taking into account the tolerance. Note 4: For the UE which supports both Band 11 and Band 21 operating frequencies, the tolerance is FFS. Note 5: When NS_20 is signalled, the total output power within 2000-2005 MHz shall be limited to 7 dBm. Note 6: For a UE that supports both Band 18 and Band 26, the maximum output power requirement is relaxed by reducing the lower tolerance limit by 1.5dB for transmission bandwidths confined within 815 MHz and 818 MHz. |
