6.2A Transmitter power for CA
38.101-23GPPNRPart 2: Range 2 StandaloneRelease 17TSUser Equipment (UE) radio transmission and reception
6.2A.1 UE maximum output power for CA
For downlink intra-band contiguous and non-contiguous carrier aggregation with a single uplink component carrier configured in the NR band, the maximum output power is specified in clause 6.2.1.
For uplink intra-band contiguous and non-contiguous carrier aggregation for any CA bandwidth class, the maximum output power is specified in clause 6.2.1.
For inter-band uplink CA with two NR bands with each UL band configured with a single CC, the maximum power requirements are applicable per band, with both carriers active with non-zero power UL RB allocation. The maximum output power values for TRP and EIRP are applicable per carrier and are specified in tables 6.2.1.x-2. The minimum peak values for EIRP are defined in Tables 6.2.1.x-1 and further relaxed by ΔTIB,P,n specified in Table 6.2A.1-x. The peak EIRP requirements are verified with the test metric of EIRP (Link=TX beam peak direction, Meas=Link angle).
The inter-band ULCA spherical coverage requirement for each power class is met if the intersection set of spherical coverage areas exceeds the common coverage requirement for that power class. For inter-band ULCA. the spherical coverage area for each band is the region of the sphere measured around the UE where the measured EIRP exceeds the EIRP level specified in Tables 6.2.1.x-3 and further reduced by the parameter ΔTIB,S,n specified in Table 6.2A.1-x. The intersection set of spherical coverage areas is defined as a fraction of area of full sphere measured around the UE where both bands meet their individual EIRP spherical coverage requirements for inter-band CA operation. The common coverage requirement is determined as <100-percentile rank> %, where ‘percentile rank’ is the percentile value in the specification of spherical coverage for that power class from Tables 6.2.1.x-3. The spherical coverage EIRP requirements are verified with the test metric of EIRP (Link=Spherical coverage grid, Meas=Link angle).
The ΔTIB parameters are specified in tables 6.2A.1-x.

6.2A.2 UE maximum output power reduction for CA
6.2A.2.1 General
The UE is defined to be configured for CA operation when it has at least one of UL or DL configured for CA. In CA operation, the UE may reduce its maximum output power due to higher order modulations and transmit bandwidth configurations. This Maximum Power Reduction (MPR) is defined in clauses below. The allowed MPR for SRS, PUCCH formats 0, 1, 3 and 4, shall be as specified for QPSK modulated DFT-s-OFDM of equivalent RB allocation. The allowed MPR for PUCCH format 2, shall be as specified for QPSK modulated CP-OFDM of equivalent RB allocation.
When the maximum output power of a UE is modified by MPR, the power limits specified in clause 6.2A.4 applyThe requirements in the following clauses are applicable to the following CA configurations:
– intra-band contiguous uplink CA, with the aggregated channel bandwidth no greater than 800 MHz.
– intra-band non-contiguous uplink CA with UL frequency separation no greater than 1400 MHz, and no more than 3 sub-blocks. A sub-block may consist of single CC or multiple contiguous CCs.
– inter-band uplink CA with two NR bands, and each UL band is configured with a single CC.
– In case the CA configuration consists of a single UL CC, MPR for contiguous UL CA applies and where necessary, BWchannel shall be used as BWchannel_CA.
6.2A.2.2 Maximum output power reduction for power class 1
6.2A.2.2.1 Maximum output power reduction for power class 1 intra-band contiguous UL CA
For power class 1, MPR for intra-band contiguous UL CA with contiguous allocations within the cumulative aggregated bandwidth is defined as:
MPRC_CA = max(MPRWT_C_CA, MPRnarrow)
Where,
MPRnarrow = 14.4 dB, when BWalloc,RB is less than or equal to 1.44 MHz, MPRnarrow = 10 dB, when 1.44 MHz < BWalloc,RB ≤ 10.8 MHz, where BWalloc,RB is the bandwidth of the RB allocation size.
MPRWT_C_CA is the maximum power reduction due to modulation orders, transmit bandwidth configurations, and waveform types. MPRWT_C_CA is defined in Tables 6.2A.2.2-1 and 6.2A.2.2-2.

In case of a contiguous RB, DFT-s-BPSK or DFT-s-QPSK UL allocation in a single CC of a CA configuration with contiguous CCs, and whose cumulative aggregated BW ≤ 400 MHz, MPRWT_C_CA shall be derived instead as MAX(MPR1, MPR2), where:

MPR2 shall be determined from Table 6.2.2.1-1 if UL BWchannel_CA ≤ 200 MHz, from Table 6.2.2.1-2 if UL BWchannel_CA > 200 MHz.
and assume all UL CCs use the same SCS for the purpose of determination of inner and outer RB allocations in Table 6.2.2.1-1 and Table 6.2.2.1-2:
NRB shall be chosen as the sum of NRB of all constituent UL CCs in the CA configuration.
LCRB shall be chosen as BWalloc,RB

MPR = max(MPRC_CA, -10*A + 14.4)
Where:
A = NRB_alloc / NRB_agg_C.
NRB_alloc is the total number of allocated UL RBs
NRB_agg_C is the number of the aggregated RBs within the fully allocated cumulative aggregated channel bandwidth assuming lowest SCS among all configured CCs

The definition of the configured UE maximum output power PCMAX,f,c for each carrier f of a serving cell c is used for power headroom reporting for carrier f of serving cell c only and is in accordance with that specified in clause 6.2.4 with parameters MPR, A-MPR and P-MPR replaced with those specified in subclause 6.2A.2, 6.2A.3 and 6.2.4, respectively. The UE maximum configured power PCMAX in a transmission occasion is determined by the UL grants for carriers f of all serving cells c with non-zero granted power in the respective reference point.
For uplink intra-band contiguous carrier aggregation, MPR is specified in clause 6.2A.2. PCMAX is calculated under the assumption that power spectral density for each RB in each component carrier is same.
The configured UE maximum output power PCMAX shall be set such that the corresponding measured total peak EIRP PUMAX is within the following bounds
PPowerclass – MAX(MAX(MPR, A-MPR) + ΔMBP,n, P-MPR) – MAX{T(MAX(MPR, A-MPR)),T(P-MPR)} ≤ PUMAX ≤ EIRPmax
with PPowerclass the UE minimum peak EIRP as specified in sub-clause 6.2A.1, EIRPmax the applicable maximum EIRP as specified in sub-clause 6.2A.1, MPR as specified in sub-clause 6.2A.2, A-MPR as specified in sub-clause 6.2A.3, ΔMBP,n the peak EIRP relaxation as specified in clause 6.2.1, P-MPR the power management term for the UE as described in 6.2.4.
The measured configured power PUMAX for carrier aggregation is defined as
where pUMAX,f,c is the linear value of the measured power PUMAX,f,c for carrier f=f(c) of serving cell c. The measured total radiated power PTMAX for carrier aggregation is defined as
where pTMAX,f,c is the linear value of the measured total radiated power PTMAX,f,c for carrier f = f(c) of serving cell c. The total radiated power PTMAX is bounded by
PTMAX ≤ TRPmax
where TRPmax the maximum TRP for the UE power class as specified in sub-clause 6.2A.1.
The tolerance T(ΔP) for applicable values of ΔP (values in dB) is specified in Table 6.2A.4.1-1 and Table 6.2A.4.1-2.

6.2A.4.2 Configured transmitted power for inter-band UL CA
A UE can configure its maximum output power for each uplink band when it is configured for inter-band UL carrier aggregation with two NR bands each with a single UL CC. For each uplink band n, the configured UE maximum output power PCMAX,f,c,n for carrier f of a serving cell c is defined as that available to the reference point of a given transmitter branch that corresponds to the reference point of the higher-layer filtered RSRP measurement as specified in TS 38.215 [11].
The configured UE maximum output power PCMAX,f,c,n for carrier f of a serving cell c in band n shall be set such that the corresponding measured peak EIRP PUMAX,f,c,n is within the following bounds
PPowerclass + DPIBE – MAX(MAX(MPRf,c,n, A- MPRf,c,n) + ΔTIB,P,n, P-MPRf,c,n) – MAX{T(MAX(MPRf,c,n, A- MPRf,c,n,)), T(P-MPRf,c,n)} ≤ PUMAX,f,c,n ≤ EIRPmax,n
while the corresponding measured total radiated power in uplink band n, PTMAX,f,c,n , is bounded by
PTMAX,f,c,n ≤ TRPmax,n
with PPowerclass the UE minimum peak EIRP as specified in sub-clause 6.2A.1, EIRPmax,n the applicable maximum EIRP as specified in sub-clause 6.2A.1 for uplink band n and TRPmax,n the applicable maximum TRP as specified in sub-clause 6.2A.1 for uplink band n. MPRf,c,n as specified in sub-clause 6.2A.2 for uplink band n, A-MPRf,c,n as specified in sub-clause 6.2A.3 for uplink band n, ΔTIB,P,n the peak EIRP relaxation as specified in clause 6.2A.1. The requirement is verified in beam peak direction.
PIBE, mpr-PowerBoost-FR2-r16 and maxUplinkDutyCycle-FR2 are described in clause 6.2.4.
P-MPRf,c,n is the power management maximum output power reduction P-MPRf,c in band n. P-MPRf,c is defined in clause 6.2.4.
The tolerance T(∆P) for applicable values of ∆P (values in dB) in each band is specified in Table 6.2.4-1.
6.2A.5 Requirements for UL gap (ul-GapFR2-r17) for TX power management in CA
The difference of the measured peak EIRP PUMAX_GAP_ON for CA when UL gap for TX power management is configured and activated, and the measured peak EIRP PUMAX_GAP_OFF when UL gap is not configured or de-activated, shall meet the following requirement:
PUMAX_GAP_ON – PUMAX_GAP_OFF max((EIRPmeas_peak – 23) + 10 * log10(Z/20), 3)dB
where EIRPmeas_peak is the measured UE peak EIRP with zero MPR/A-MPR/P-MPR in clause 6.2A.1 for the corresponding power class, and Z% is duty cycle of the reference measurement channel. PUMAX,f,c_GAP_ON shall be measured outside of the UL gap symbol(s). The period of measurement shall be at least 4 seconds. The requirement is verified with the test metric of EIRP (Link=TX beam peak direction, Meas=Link angle) and in the test Z is set to 20 when maxUplinkDutyCycle-FR2 is less than 20 or not reported, and should be larger than maxUplinkDutyCycle-FR2 when maxUplinkDutyCycle-FR2 is equal to or greater than 20, assuming all CCs share the same TX beam peak direction. The reference measurement channel is specified in Annex A.2.3.
When UL gap for Tx power management is configured and activated, the reported P-MPRf,c shall be less than 3dB. When UL gap for Tx power management is not configured and activated, UE shall set the P bit in PHR to 1 in the test when PHR is configured. P-bit is defined in TS 38.321 clause 6.1.3.8 and 6.1.3.9.
