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 Table 5.5G-1, the requirements in subclause 6.3.5G.1 apply for E-UTRA V2X sidelink transmission.

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 requirements in subclause 6.3.5G.1 apply for V2X sidelink transmission and the requirements in subclause 6.3.5 apply for the E-UTRA uplink transmission.

For V2X UE supporting Transmit Diversity, if the UE transmits on two antenna connectors at the same time, the power control tolerance for single carrier shall apply to the sum of output power at each transmit antenna connector.

If the UE transmitson one -antenna connector at a time, the requirements for single carrier shall apply to the active antenna connector.

6.3.5G.1 Absolute power tolerance

Absolute power tolerance is the ability of the UE to set its output power to a specific value for each subframe.

For V2X sidelink communication transmissions in the operating bands specified in Table 5.5G-1, the minimum requirement for absolute power tolerance is given in Table 6.3.5G.1-1 over the power range bounded by the Maximum output power as defined in subclause 6.2.2G and the Minimum output power as defined in subclause 6.3.2G.

For operating bands under NOTE 2 in Table 6.2.2-1, the absolute power tolerance as specified in Table 6.3.5G.1-1 is relaxed by reducing the lower limit by 1.5 dB when the transmission bandwidth is confined within F_{UL_low} and F_{UL_low} + 4 MHz or F_{UL_high} – 4 MHz and F_{UL_high}.

Table 6.3.5G.1-1: Absolute power tolerance

Conditions	Tolerance
Normal	± 9.0 dB
Extreme	± 12.0 dB

For intra-band contiguous multi-carrier operation the absolute power control tolerance specified in Table 6.3.5G.1-1 shall apply for each component carrier.
