NOTE 1: For the con-current band combinations, the simultaneous transmission and reception of sidelink and Uu interfaces can be supported while operation is agnostic of the service used on each interface. NOTE 2: PPowerClass is the maximum output power specified without taking into account the tolerance for each operation band. NOTE 3: For inter-band con-current operation, the aggregation power 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 |

6.2E.2.1 UE maximum output power reduction for Intra-band V2X
For intra-band V2X operating UE, maximum output power reduction specified in clause 6.2.3G [4] and in clause 6.2E.2 [2] apply, respectively.
6.2E.2.2 UE maximum output power reduction for Inter-band V2X
For the inter-band con-current NR V2X operation, the allowed maximum power reduction (MPR) for the maximum output power shall be applied per each component carrier. The MPR requirements in subclause 6.2.3 of TS 36.101 [4] apply for E-UTRA Uu operation in licensed band, and the MPR requirements in subclause 6.2E.2 of TS 38.101-1 [2] apply for NR sidelink operation. The MPR requirements in subclause 6.2.3G of TS 36.101 [4] apply for E-UTRA V2X operation, and the MPR requirements in subclause 6.2.2 of TS 38.101-1 [2] apply for NR Uu operation.

6.2E.3.2 UE additional maximum output power reduction for Inter-band V2X
For the inter-band con-current NR V2X operation, the allowed additional maximum power reduction (A-MPR) for the maximum output power shall be applied per each component carrier. The A-MPR requirements in subclause 6.2.3 of TS 36.101 [4] apply for E-UTRA Uu operation in licensed band, and the A-MPR requirements in in subclause 6.2C.3 of TS 38.101-1 [2] apply for NR sidelink operation in Band n47.

6.2E.4.1 UE configured output power for Intra-band V2X
For intra-band V2X operating UE, each UE configured output power specified in clause 6.2.5G [4] and in clause 6.2E.4 [2] apply, respectively.
6.2E.4.2 UE configured output power for Inter-band V2X
When a UE is configured for simultaneous NR V2X sidelink and NR uplink transmissions for inter-band con-current operation, the UE is allowed to set its configured maximum output power PCMAX,c,Uu and PCMAX,c,V2X for the configured E-UTRA or NR uplink carrier and the configured NR V2X SL or E-UTRA V2X SL carrier, respectively, and its total configured maximum output power PCMAX,c. The TIB,V2X of PCMAX,c,Uu is specified in Table 6.2E.4.2-1.
The configured maximum output power PCMAX c,Uu(p) in subframe p for the configured E-UTRA or NR uplink carrier shall be set within the bounds:
PCMAX_L,c, Uu (p) ≤ PCMAX,c, Uu (p) ≤ PCMAX_H,c, Uu (p)
where PCMAX_L,c,Uu and PCMAX_H,c, Uu are the limits for a serving cell c as specified in subclause 6.2.5 TS 36.101 [4] or 6.2.4 TS 38.101-1 [2].
The configured maximum output power PCMAX c,V2X (q) in slot q for the configured NR or E-UTRA V2X SL carrier shall be set within the bounds:
PCMAX,c,V2X (q) ≤ PCMAX_H,c,V2X (q)
where PCMAX_H,c,V2X is the limit as specified in subclause 6.2E.4 of TS 38.101-1 [2] or 6.2.5G of TS 36.101 [5].
The total UE configured maximum output power PCMAX (p,q) in a subframe p of E-UTRA uplink carrier and a slot q of NR V2X sidelink that overlap in time shall be set within the following bounds for synchronous and asynchronous operation unless stated otherwise:
PCMAX_L (p,q) ≤ PCMAX (p,q) ≤ PCMAX_H (p,q)
with
PCMAX_L (p,q) = PCMAX_L,c,Uu (p)
PCMAX_H (p,q) = 10 log10 [pCMAX_H,c, Uu (p) + pCMAX_H,c,V2X (q)]
where pCMAX_H,c,V2X and pCMAX_H,c,Uu are the limits PCMAX_H,c,V2X (q) and PCMAX_H,c,Uu (p) expressed in linear scale.
The measured total maximum output power PUMAX over both the E-UTRA uplink and NR V2X carriers is
PUMAX = 10 log10 [pUMAX,c,Uu + pUMAX,c,V2X],
where pUMAX,c,Uu denotes the measured output power of serving cell c for the configured E-UTRA uplink carrier or NR uplink carrier, and pUMAX,c,V2X denotes the measured output power for the configured NR V2X SL carrier or E-UTRA V2X SLcarrier expressed in linear scale.
When a UE is configured for synchronous V2X sidelink and uplink transmissions,
PCMAX_L(p, q) – TLOW (PCMAX_L(p, q)) ≤ PUMAX ≤ PCMAX_H(p, q) + THIGH (PCMAX_H(p, q))
where PCMAX_L (p,q) and PCMAX_H (p,q) are the limits for the pair (p,q) and with the tolerances TLOW(PCMAX) and THIGH(PCMAX) for applicable values of PCMAX specified in Table 6.2E.4-1. PCMAX_L may be modified for any overlapping portion of slots (p, q) and (p +1, q+1).
