RBStart,Low = max(1, floor(NRB_alloc + (BWgap – BWGB,low)/0.18MHz))
RBStart,High = floor((BWChannel_SL&UL – 2 ∙ BWgap – BWGB,low)/0.18MHz – 2 ∙ NRB_alloc)

In contiguous NR V2X intra-band con-current operation, a non-contiguous RB allocation is a non-contiguous outer 1 RB allocation if the following conditions are met:

RBStart,Low = max(1, 2 ∙ NRB_alloc – floor( (BWChannel_SL&UL – 2 ∙ BWgap + BWGB,low)/0.18MHz)),
RBStart,High = floor((2 ∙ BWChannel_SL&UL – 3 ∙ BWgap – BWGB,low) / 0.18MHz – 3 ∙ NRB_alloc)

6.2E.3 UE additional maximum output power reduction for V2X
6.2E.3.1 General
For the applied maximum output power reduction is obtained by taking the maximum value of MPR requirements specified in clause 6.2E.2 and A-MPR requirements specified in current clause.
Additional emission requirements can be indicated by the network or pre-configured radio parameters. Each additional emission requirement is associated with a unique network signalling (NS) value indicated in RRC signalling by an NR frequency band number of the applicable operating band and an associated value in the field [additionalSpectrumEmission]. Throughout this specification, the notion of indication or signalling of an NS value refers to the corresponding indication of an NR V2X frequency band number of the applicable operating band, the IE field [freqBandIndicatorNR] and an associated value of [additionalSpectrumEmission] in the relevant RRC information elements [7].
To meet the additional requirements, additional maximum power reduction (A-MPR) is allowed for the maximum output power as specified in Table 6.2.1-1. Outer and inner allocation notation used in clause 6.2E.3 is defined in clause 6.2E.2. In absence of modulation and waveform types the A-MPR applies to all modulation and waveform types.

For UE with two transmit antenna connectors, the A-MPR values specified in clause 6.2E.3.2 and 6.2E.3.3 shall apply to the maximum output power specified in Table 6.2E.1.1-1. The requirements shall be met with the SL MIMO configurations specified in Table 6.2D.1-2. For UE supporting SL MIMO or Tx Diversity, the maximum output power is defined as the sum of the maximum output power from each UE antenna connector. Unless stated otherwise, an A-MPR of 0 dB shall be used.
For the UE maximum output power modified by A-MPR, the power limits specified in clause 6.2E.4 apply.
6.2E.3.2 A-MPR for V2X UE by NS_33
When NS_33 is indicated by the network or pre-configured radio parameters for NR V2X UE, the additional maximum output power reduction specified as
A-MPR = CEIL {MA, 0.5}
Where MA is defined as follows
MA = A-MPRBase + Gpost connector* A-MPRStep
CEIL{MA, 0.5} means rounding upwards to closest 0.5dB.
A-MPRBase and A-MPRStep are specified in Tables 6.2E.3.2-1, 6.2E.3.2-2 is allowed when network signalling value is provided. A-MPRBase is the default A-MPR value when no Gpost connector is declared. The supported post antenna connector gain Gpost connector is declared by the UE following the principle described in annex I in [11]. The A-MPRstep is the increase in A-MPR allowance to allow UE to meet tighter conducted A-SE and A-SEM requirements with higher value of declared Gpost connector.
For the contiguous PSSCH and PSCCH transmission when NS_33 is indicated by the network or pre-configured radio parameters for NR V2X UE, the NR UE allow the follow A-MPR requirements specified in Table 6.2E.3.2-1 and 6.2E.3.2-2 for power class 3. And A-MPR requirements specified in Table 6.2E.3.2-2a and 6.2E.3.2-2b for power class 2 are allowed for NR V2X UE.

6.2E.4.2 Configured transmitted power for inter-band V2X con-current operation
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,NR and PCMAX,c,V2X for the configured NR uplink carrier and the configured NR V2X carrier, respectively, and its total configured maximum output power PCMAX,c.
The configured maximum output power PCMAX c,NR(p) in slot p for the configured NR uplink carrier shall be set within the bounds:
PCMAX_L,c,NR (p) ≤ PCMAX,c,NR (p) ≤ PCMAX_H,c,NR (p)
where PCMAX_L,c,NR and PCMAX_H,c,NR are the limit as specified in clause 6.2E.4.1.
The configured maximum output power PCMAX c,V2X (q) in slot q for the configured NR V2X 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 clause 6.2E.4.
The total UE configured maximum output power PCMAX (p,q) in a slot p of NR 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_H (p,q) = 10 log10 [pCMAX_H,c,NR (p) + pCMAX_H,c,V2X (q)]
where pCMAX_H,c,V2X and pCMAX_H,c,NR are the limits PCMAX_H,c,V2X (q) and PCMAX_H,c,NR (p) expressed in linear scale.
The measured total maximum output power PUMAX over both the NR uplink and NR V2X carriers is
PUMAX = 10 log10 [pUMAX,c,NR + pUMAX,c,V2X],
where pUMAX,c,NR denotes the measured output power of serving cell c for the configured NR uplink carrier, and pUMAX,c,V2X denotes the measured output power for the configured NR V2X carrier 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.4.1-1.. PCMAX_L may be modified for any overlapping portion of slots (p, q) and (p +1, q+1).
6.2E.4.3 Configured transmitted power for intra-band V2X con-current operation
For intra-band con-current operation, if transmission of Uu and SL does not overlap in time, the configured output power PCMAX,c specified in clause 6.2E.4.1 and 6.2.4 apply for SL and Uu transmission respectively; otherwise, if transmission of Uu and SL overlap in time, the configured maximum output power PCMAX,c on serving cell c for SL and Uu shall be set as specified in clause 6.2E.4.1 and in clause 6.2.4, but with MPRc = MPR and A-MPRc = A-MPR with MPR and A-MPR as determined by subclause 6.2E.2.3 for both PC3 and PC2 and subclause 6.2E.3.4, respectively. There is one power management term for the UE, denoted P-MPR, and P-MPR c = P-MPR.
The total configured maximum output power PCMAX shall be set within the following bounds:
PCMAX_L ≤ PCMAX ≤ PCMAX_H
For intra-band concurrent operation when same slot pattern is used in all aggregated serving cells,
PCMAX_L = MIN{10 log10 ∑ pEMAX,c – TC , PPowerClass,con-current – MAX(MAX(MPR, A-MPR) + ΔTIB,c + TC, P-MPR ) }
PCMAX_H = MIN{10 log10 ∑ pEMAX,c , PPowerClass,con-current}
where
– pEMAX,c is the linear value of PEMAX,c which is given by IE P-Max for Uu serving cell c or by IE sl-MaxTransPower for SL defined in [7];
– PPowerClass,con-current is the maximum UE power specified in Table 6.2E.1.2-2 without taking into account the tolerance;
– MPR and A-MPR are specified in clause 6.2E.2 and 6.2E.3, respectively;
– TIB,c is the additional tolerance for serving cell c as specified in clause 6.2E.4.3
– P-MPR is the power management term for the UE;
– TC is the highest value TC,c among all serving cells c;
For intra-band concurrent operation, when at least one different numerology/slot pattern is used in aggregated cells, the UE is allowed to set its configured maximum output power PCMAX,c(i),i for serving cell c(i) of slot numerology type i, and its total configured maximum output power PCMAX.
The configured maximum output power PCMAX,c(i),i (p) in slot p of serving cell c(i) on slot numerology type i shall be set within the following bounds:
PCMAX_L,f,c(i),i (p) ≤ PCMAX,f,c(i), i (p) ≤ PCMAX_H,f,c(i),i (p)
where PCMAX_L,f,c (i),i (p) and PCMAX_H,f,c(i),i (p) are the limits for a serving cell c(i) of slot numerology type i as specified in clause 6.2.4.
The total UE configured maximum output power PCMAX (p,q) in a slot p of slot numerology or symbol pattern i, and a slot q of slot numerology or symbol pattern j that overlap in time shall be set within the following bounds unless stated otherwise:
PCMAX_L(p,q) ≤ PCMAX (p,q) ≤ PCMAX_H (p,q)
When slots p and q have different transmissions lengths and belong to different cells on same band for intra-band operation:
PCMAX_L (p,q) = MIN {10 log10 [pCMAX_L,f,c(i),Uu,i (p) + pCMAX_L,f,c(i),V2X,j (q)], PPowerClass,con-current}
PCMAX_H (p,q) = MIN {10 log10 [pCMAX_ H,f,c(i), Uu,,i (p) + pCMAX_ H,f,c(i),V2X,j (q)], PPowerClass,con-current}
where pCMAX_L,f,c (i),Uu,i and pCMAX_ H,f,c(i),Uu,i are the respective limits PCMAX_L,f,c (i),Uu,i and PCMAX_H,f,c(i),Uu,i expressed in linear scale.
TREF and Teval are specified in Table 6.2E.4.3-1 when same and different slot patterns are used in aggregated carriers. For each TREF, the PCMAX_L is evaluated per Teval and given by the minimum value taken over the transmission(s) within the Teval; the minimum PCMAX_L over the one or more Teval is then applied for the entire TREF. PPowerClass,Concurrent shall not be exceeded by the UE during any period of time.

The measured maximum output power PUMAX over all serving cells with same slot pattern shall be within the following range:
PCMAX_L – MAX{TL, TLOW(PCMAX_L) } ≤ PUMAX ≤ PCMAX_H + THIGH(PCMAX_H)
PUMAX = 10 log10 ∑ pUMAX,c
where pUMAX,c denotes the measured maximum output power for serving cell c expressed in linear scale. The tolerances TLOW(PCMAX) and THIGH(PCMAX) for applicable values of PCMAX are specified in Table 6.2E.4.3-2. The tolerance TL is the absolute value of the lower tolerance for applicable NRV2X concurrent operation configuration as specified in Table 6.2 E.1.2-2 for intra-band NR V2X concurrent operation.
The measured maximum output power PUMAX over all serving cells, when at least one slot has a different transmission numerology or slot pattern, shall be within the following range:

where p’UMAX,c denotes the average measured maximum output power for serving cell c expressed in linear scale over TREF. The tolerances TLOW(P’CMAX) and THIGH(P’CMAX) for applicable values of P’CMAX are specified in Table 6.2E.4.3-2.

For sidelink resource allocation in either mode 1 or mode 2, if UE is in RRC_CONNECTED state, and the preparation procedure time for transmission of sidelink physical channel is available before of PUSCH preparation procedure time, for transmission of Uu and SL not overlap in time, the configured output power PCMAX,c specified in clause 6.2E.4.1 and in clause 6.2.4 apply for SL and Uu transmission respectively, otherwise, the configured maximum output power PCMAX specified in this clause shall apply.
For sidelink resource allocation mode 2, if UE is in RRC_IDLE state, sidelink transmission is based on pre-configured sidelink resource pool, the UE configured output power is determined by sidelink only, where the configured output power specified in clause 6.2E.4.1 apply.
For sidelink resource allocation mode 2, if UE is in RRC_INACTIVE state, and Uu does not support SDT, the configured output power specified in clause 6.2E.4.1 apply, otherwise, the configured maximum output power PCMAX in this clause shall apply.
