6.2.2G UE maximum output power for V2X Communication
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, the allowed V2X UE maximum output power for shall be as applied in Table 6.2.2-1 in subclause 6.2.2.
For V2X 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 UE maximum output power shall be as specified in Table 6.2.2G-1 in subclause 6.2.2G for the corresponding inter-band con-current operation with uplink assigned to two bands.

NOTE 1: The con-current band combinations is used for V2X Service. NOTE 2: PPowerClass is the maximum UE power specified without taking into account the tolerance NOTE 3: For inter-band con-current aggregation the maximum power requirement apply to the total transmitted power over all component carriers (per UE). NOTE 4: 4 refers to the transmission bandwidths (Figure 5.6-1) 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 |
||||||||
For intra-band contiguous multi-carrier operation, the maximum output power is defined in Table 6.2.2G-2.

When a UE is configured for E-UTRA V2X sidelink transmissions in Band 47, the UE shall meet the following additional requirements for transmission within the frequency ranges 5855-5925 MHz:
– The maximum mean power spectral density shall be restricted to 23 dBm/MHz EIRP when the network signaling value NS_33 or NS_34 is indicated.
where the network signaling values are specified in clause 6.2.4G.
NOTE: The PSD limit in EIRP shall be converted to conducted requirement depend on the supported post antenna connector gain Gpost connector declared by the UE following the principle described in annex I.
For V2X UE supporting Transmit Diversity, if the UE transmits on two connectors at the same time, the maximum output power for any transmission bandwidth within the channel bandwidth is specified in Table 6.2.2G-3. The maximum output power is measured as the sum of the maximum output power at each UE antenna connector. The period of measurement shall be at least one sub frame (1ms).
