6.2A.4.0 Minimum conformance requirements
A UE configured with carrier aggregation can configure its maximum output power for each uplink carrier f of activated serving cell c and its total configured output power PCMAX. 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 below. 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 subclause 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 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.4.0-1.
