6.2.3G.1 Maximum Power Reduction (MPR) for V2X Communication / Power class 3

6.2.3G.1.1 Maximum Power Reduction (MPR) for V2X Communication / Power class 3 / Contiguous allocation of PSCCH and PSSCH / Non-concurrent with E-UTRA uplink transmissions

6.2.3G.1.1.1 Test purpose

To verify that the error of the UE maximum output power does not exceed the range prescribed by the specified nominal maximum output power and tolerance covering configurations where a maximum power reduction is allowed in the UE.

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.

6.2.3G.1.1.2 Test applicability

The requirements of this test apply in the test case 6.6.2.3G Adjacent Channel Leakage power Ratio for V2X Communication to all types of UE that support V2X Sidelink communication and Band 47.

NOTE: As a result TC 6.2.3G.1.1 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.

6.2.3G.1.1.3 Minimum conformance requirements

When UE is configured for E-UTRA V2X sidelink transmissions non-concurrent with E-UTRA uplink transmissions for E-UTRA V2X operating bands specified in Table 5.2G-1, this subclause specifies the allowed Maximum Power Reduction (MPR) power for V2X physical channels and signals due to PSCCH and PSSCH simultaneous transmission.

For contiguous allocation of PSCCH and PSSCH simultaneous transmission, the allowed MPR for the maximum output power for V2X physical channels PSCCH and PSSCH shall be as specified in Table 6.2.3G.1.1.3-1 for power class 3.

6.2.3G.2.1.1 Test purpose

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.

6.2.3G.2.1.2 Test applicability

The requirements of this test apply in the test case 6.6.2.3G Adjacent Channel Leakage power Ratio for V2X Communication to all types of UE that support V2X Sidelink communication and Band 47.

NOTE: As a result TC 6.2.3G.2.1 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.

2.5 ; 0.3< A ≤1.00

For 20MHz channel bandwidth M_A = 9.0 ; 0.0< A ≤ 0.1

12.0 – 30.0A ; 0.1< A ≤0.3

3.0 ; 0.3< A ≤1.00

Where

A = N_{RB_alloc} / N_RB.

CEIL{M_A, 0.5} means rounding upwards to closest 0.5dB.
