36.1013GPPEvolved Universal Terrestrial Radio Access (E-UTRA)Release 18TSUser Equipment (UE) radio transmission and reception

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 5.5G-1, this subclause specifies the allowed Maximum Power Reduction (MPR) power for V2X physical channels and signals due to PSCCH and PSSCH simultaneous transmission.

6.2.3G.1 MPR for Power class 3 V2X UE

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 for power class 3.

Table 6.2.3G.1-1: Maximum Power Reduction (MPR) for power class 3 V2X Communication (Contiguous PSCCH and PSSCH transmission)

Modulation	Channel bandwidth / Transmission bandwidth (NRB)						MPR (dB)
	1.4 MHz	3.0 MHz	5 MHz	10 MHz	15 MHz	20 MHz
QPSK							≤ 1.5
16 QAM							≤ 2
64QAM							≤ 3

For non-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 as follows

MPR = CEIL {M_A, 0.5}

Where M_A is defined as follows

M_A = 4.5 ; 0.00< A ≤ 0.2

5.5 –5.833A ; 0.2< A ≤0.6

2.0 ; 0.6< A ≤1.00

Where

A = N_{RB_alloc} / N_RB.

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

The allowed MPR for the maximum output power for V2X physical channels PSBCH and PSSS shall be as specified in subclause 6.2.3 for the corresponding modulation and transmission bandwidth.

The allowed MPR for the maximum output power for V2X physical signal SSSS is specified in Table 6.2.3D-1.

When UE is configured for simultaneous E-UTRA V2X sidelink and E-UTRA uplink transmissions for inter-band E-UTRA V2X / E-UTRA bands specified in Table 5.5G-2, the allowed MPR requirements in subclause 6.2.3G apply for V2X PSSCH and PSCCH transmission. The allowed MPR requirements in subclause 6.2.3D apply for other V2X sidelink transmission (PSBCH/PSSS/SSSS). The MPR requirements in subclause 6.2.3 apply for uplink transmission.

For intra-band contiguous multi-carrier operation bandwidth class B the allowed Maximum Power Reduction (MPR) for the maximum output power in Table 6.2.2G.1-2 due to higher order modulation is specified as follows.

Table 6.2.3G.1-2: Void

MPR = CEIL { M_A, 0.5}

Where M_A is defined as follows for QPSK, 16 QAM and 64 QAM

M_A = 6.5 ; 0 ≤ A < 0.1

8 – 15A ; 0.1 ≤ A < 0.2

5.75 – 3.75A ; 0.2 ≤ A < 0.6

3.5 ; 0.6≤ A ≤ 1For intra-band contiguous multi-carrier operation bandwidth class C the allowed Maximum Power Reduction (MPR) for the maximum output power can be specified as follows. In case the modulation format is different on different component carriers then the MPR is determined by the rules applied to higher order of those modulations.

MPR = CEIL { M_A, 0.5}

Where M_A is defined as follows for QPSK, 16 QAM and 64 QAM

[M_A = 6.5 ; 0 ≤ A < 0.1

8.5 – 20A ; 0.1 ≤ A < 0.2

5.25 – 2.5A ; 0.2 ≤ A < 0.6

3.5 ; 0.6≤ A ≤ 1]

6.2.3G.2 MPR for Power class 2 V2X UE

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.2-1 for power class 2.

Table 6.2.3G.2-1: Maximum Power Reduction (MPR) for power class 2 V2X Communication (Contiguous PSCCH and PSSCH transmission)

Modulation	Channel bandwidth / Transmission bandwidth (NRB)						MPR (dB)
	1.4 MHz	3.0 MHz	5 MHz	10 MHz	15 MHz	20 MHz
QPSK							≤ 2
16 QAM							≤ 2.5

For non-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 as follows:

MPR = CEIL {M_A, 0.5}

Where M_A is defined as follows

For 10MHz channel bandwidth M_A = 4.5 ; 0.0< A ≤ 0.2

8.5 – 20.0A ; 0.2< A ≤0.3

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.
