Section: 6.2.5A Configured transmitted power for CA
Content: For uplink carrier aggregation the UE is allowed to set its configured maximum output power PCMAX,c for serving cell c and its total configured maximum output power PCMAX. The configured maximum output power PCMAX,c on serving cell c shall be set as specified in subclause 6.2.5. For uplink inter-band carrier aggregation, MPRc and A-MPRc apply per serving cell c and are specified in subclause 6.2.3 and subclause 6.2.4, respectively. P-MPR c accounts for power management for serving cell c. PCMAX,c is calculated under the assumption that the transmit power is increased independently on all component carriers. For uplink intra-band contiguous and non-contiguous carrier aggregation, MPRc = MPR and A-MPRc = A-MPR with MPR and A-MPR specified in subclause 6.2.3A and subclause 6.2.4A respectively. There is one power management term for the UE, denoted P-MPR, and P-MPR c = P-MPR. PCMAX,c is calculated under the assumption that the transmit power is increased by the same amount in dB on all component carriers. The total configured maximum output power PCMAX shall be set within the following bounds: PCMAX_L ≤ PCMAX ≤ PCMAX_H For uplink inter-band carrier aggregation with one serving cell c per operating band when same TTI pattern is used in all aggregated serving cells, PCMAX_L = MIN {10log10∑ MIN [ pEMAX,c/ (tC,c), pPowerClass/(mprc·a-mprc·tC,c ·tIB,c·tProSe) , pPowerClass/pmprc], PPowerClass} PCMAX_H = MIN{10 log10 ∑ pEMAX,c , PPowerClass} where - pEMAX,c is the linear value of PEMAX, c which is given by IE P-Max for serving cell c in [7]; - PPowerClass is the maximum UE power specified in Table 6.2.2A-1 without taking into account the tolerance specified in the Table 6.2.2A-1; pPowerClass is the linear value of PPowerClass; - mpr c and a-mpr c are the linear values of MPR c and A-MPR c as specified in subclause 6.2.3 and subclause 6.2.4, respectively; - pmprc is the linear value of P-MPR c; - tC,c is the linear value of TC,ctC,c = 1.41 when NOTE 2 in Table 6.2.2-1 applies for a serving cell c, otherwise tC,c = 1; - tIB,c is the linear value of the inter-band relaxation term TIB,c of the serving cell c as specified in Table 6.2.5-2; otherwise tIB,c - tProSe is the linear value of TProSe and applies as specified in subclause 6.2.5. For uplink intra-band contiguous and non-contiguous carrier aggregation when same TTI pattern is used in all aggregated serving cells, PCMAX_L = MIN{10 log10 ∑ pEMAX,c - TC , (PPowerClass – ΔPPowerClass) – MAX(MPR + A-MPR + ΔTIB,c + TC + TProSe, P-MPR ) } PCMAX_H = MIN{10 log10 ∑ pEMAX,c , PPowerClass} where - pEMAX,c is the linear value of PEMAX,c which is given by IE P-Max for serving cell c in [7]; - PPowerClass is the maximum UE power specified in Table 6.2.2A-1 without taking into account the tolerance specified in the Table 6.2.2A-1; ΔPPowerClass = 3 dB for a power class 2 capable UE operating in Band 41, when P-max of 23 dBm or lower is indicated or if the uplink/downlink configuration is 0 or 6 in the cell; otherwise, ΔPPowerClass = 0 dB - MPR and A-MPR are specified in subclause 6.2.3A and subclause 6.2.4A respectively; - TIB,c is the additional tolerance for serving cell c as specified in Table 6.2.5-2; - P-MPR is the power management term for the UE; - TC is the highest value TC,c among all serving cells c in the TREF over all Teval durations. TC,c = 1.5 dB when NOTE 2 in Table 6.2.2A-1 applies to the serving cell c, otherwise TC,c = 0 dB; - TProSe applies as specified in subclause 6.2.5. For uplink inter-band carrier aggregation with one serving cell c per operating band when at least one different TTI patterns 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 TTI length i, i = 1,2,3 and its total configured maximum output power PCMAX. The configured maximum output power PCMAX,c(i),i (p) in TTI p of serving cell c(i) on TTI length i shall be set within the following bounds: PCMAX_L,c(i),i (p) ≤ PCMAX,c(i), i (p) ≤ PCMAX_H,c(i),i (p) where PCMAX_L,c(i),i (p) and PCMAX_H,c(i),i (p) are the limits for a serving cell c(i) of TTI length i as specified in subclause 6.2.5. The total UE configured maximum output power PCMAX (p,q,k) in a TTI p of TTI length 1 , a TTI q of TTI length 2 and a TTI k of TTI length 3 that overlap in time shall be set within the following bounds unless stated otherwise: PCMAX_L(p,q,k) ≤ PCMAX (p,q,k) ≤ PCMAX_H (p,q,k) When p, q, k are of different lengths and belong to different cells: PCMAX_L (p,q,k) = MIN {10 log10 [pCMAX_L,c(1),1 (p) + pCMAX_L,c(2),2 (q)+ + pCMAX_L,c(3),3 (k)], PPowerClass} PCMAX_H (p,q,k) = MIN {10 log10 [pCMAX_H,c(1),1 (p) + pCMAX_H,c(2),2 (q) + pCMAX_H,c(3),3 (k)], PPowerClass} where pCMAX_L,c(i),i and pCMAX_H,c(i),i are the respective limits PCMAX_L,c(i),iand PCMAX_H,c(i),i expressed in linear scale. For combinations of intra-band and inter-band carrier aggregation with UE configured for transmission on three serving cells (up to two contiguously aggregated carriers per operating band), For the case when p and q belong to the same band and k belongs to a different band but p, q and k are of the same TTI pattern. PCMAX_L = MIN {10log10∑(pCMAX_L, Bi), PPowerClass} PCMAX_H = MIN{10 log10 ∑ pEMAX,c , PPowerClass} For the case when p and q belong to the same band and are of the same TTI pattern while k belong to a different band and is of different TTI pattern then: PCMAX_L (p,q,k) = MIN {10 log10 [pCMAX_L,Bi(p) + pCMAX_L,c(3),3 (k)], PPowerClass} PCMAX_H (p,q,k) = MIN {10 log10 [pCMAX_H,Bi (p) + pCMAX_H,c(3),3 (k)], PPowerClass} where - pEMAX,c is the linear value of PEMAX, c which is given by IE P-Max for serving cell c in [7]; - PPowerClass is the maximum UE power specified in Table 6.2.2A-0 without taking into account the tolerance specified in the Table 6.2.2A-0; pPowerClass is the linear value of PPowerClass; - pCMAX_L, Bi is the linear values of PCMAX_L as specified in corresponding operating band. PCMAX_L,c specified for single carrier in subclause 6.2.5 applies for operating band supporting one serving cell. PCMAX_L specified for uplink intra-band contiguous carrier aggregation in subclause 6.2.5A applies for operating band supporting two contiguous serving cells. - intra-band carriers use the same TTI patterns. TREF and Teval are specified in Table 6.2.5A-0 when same and different TTI 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 shall not be exceeded by the UE during any period of time. Table 6.2.5A-0: PCMAX evaluation window for different TTI patterns If the UE is configured with multiple TAGs and transmissions of the UE on TTI i for any serving cell in one TAG overlap some portion of the first symbol of the transmission on TTI i +1 for a different serving cell in another TAG, the UE minimum of PCMAX_L for TTIs i and i + 1 applies for any overlapping portion of TTIs i and i + 1. PPowerClass shall not be exceeded by the UE during any period of time. In case PC2 and uplink intra-band contiguous CA capable UE receives pEMAX,c in Scell then that applies both to Scell and Pcell once the Scell is activated. The measured maximum output power PUMAX over all serving cells with same TTI 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.
