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 total configured power PCMAX in a transmission occasion is the sum of the configured power for carrier f of serving cell c with non-zero granted transmission 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 total 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),P-MPR) – MAX{T(MAX(MPR, A_MPR)),T(P-MPR)} ≤ PUMAX ≤ EIRPmax

with PPowerclass the UE power class 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, P-MPR the power management term for the UE as described in 6.2.4 and TRPmax the maximum TRP for the UE power class as specified in sub-clause 6.2A.1.

PUMAX is defined as 10*log10(∑pUMAX,fIi),c(j)) for each carrier f (i=1…n) and serving cell c (j=1…m) where pUMAX,fIi),c(j) is linear value of PUMAX,fIi),c(j)

The tolerance T(ΔP) for applicable values of ΔP (values in dB) is specified in Table 6.2A.4-1.
