6.2H.1 Transmitter power for intra-band UL contiguous CA with UL MIMO
6.2H.1.1 UE maximum output power for intra-band UL contiguous CA with UL MIMO
For intra-band UL contiguous CA and UE with two transmit antenna connectors in closed-loop spatial multiplexing scheme, the maximum output power is defined as the sum of the maximum output power from both UE antenna connectors and all UL CCs. The period of measurement shall be at least one sub frame (1 ms), as specified in Table 6.2H.1.1-1. The requirements shall be met with the UL MIMO configurations specified in Table 6.2D.1-2 and 6.2D.1-3 for 2 layer configuration and ULFPTx configuration respectively.

NOTE 1: If all transmitted resource blocks over all component carriers are confined within FUL_low and FUL_low + 4 MHz or/and FUL_high – 4 MHz and FUL_high, the maximum output power requirement is relaxed by reducing the lower tolerance limit by 1.5 dB NOTE 2: PPowerClass is the maximum UE power specified without taking into account the tolerance |

If UE is scheduled for single antenna-port PUSCH transmission by DCI format 0_0 or by DCI format 0_1 for single antenna port codebook based transmission, the requirements in clause 6.2A.1.1 apply for at least one antenna connector for the power class as indicated by the ue-PowerClass field in capability signalling.
6.2H.1.2 UE maximum output power reduction for intra-band UL contiguous CA with UL MIMO
For intra-band UL contiguous CA and UE with two transmit antenna connectors in closed-loop spatial multiplexing scheme, the allowed Maximum Power Reduction (MPR) for the maximum output power in Table 6.2H.1.1-1 is specified in Table 6.2A.2.1-1, Table 6.2A.2.1-2 for power class 3 CA; Table 6.2A.2.1-1b, Table 6.2A.2.1-4 for power class 2 CA.
The requirements shall be met with UL MIMO configurations defined in Table 6.2D.1-2 and 6.2D.1-3 for 2 layer configuration and ULFPTx configuration respectively. For the UE maximum output power modified by MPR, the power limits specified in clause 6.2H.1.4 apply.
If UE is scheduled for single antenna-port PUSCH transmission by DCI format 0_0 or by DCI format 0_1 for single antenna port codebook based transmission, the requirements in clause 6.2A.2.1 apply for the power class as indicated by the ue-PowerClass field in capability signaling.
6.2H.1.3 UE additional maximum output power reduction for intra-band UL contiguous CA with UL MIMO
For intra-band UL contiguous CA and UE with two transmit antenna connectors in closed-loop spatial multiplexing scheme, the A-MPR values specified in clause 6.2A.3 shall apply to the maximum output power specified in Table 6.2H.1.1-1. The requirements shall be met with UL MIMO configurations defined in Table 6.2D.1-2 and 6.2D.1-3 for 2 layer configuration and ULFPTx configuration respectively.
For the UE maximum output power modified by A-MPR, the power limits specified in clause 6.2H.1.4 apply.
If UE is scheduled for single antenna-port PUSCH transmission by DCI format 0_0 or by DCI format 0_1 for single antenna port codebook based transmission, the requirements in clause 6.2 A.3.1 apply for the power class as indicated by the ue-PowerClass field in capability signaling.
6.2H.1.4 Configured transmitted power for intra-band UL contiguous CA with UL MIMO
For UE supporting intra-band UL contiguous CA with UL MIMO, the transmitted power is configured per each UE.
The definitions of configured maximum output power PCMAX,c, the lower bound PCMAX_L,c, and the higher bound PCMAX_H,c specified in clause 6.2A.4.1.1 shall apply to UE supporting intra-band UL contiguous CA with UL MIMO, where
– ΔPPowerClass and ∆TC,c are specified in clause 6.2A.4 unless otherwise stated;
– PPowerClass,CA is the maximum UE power specified in Table 6.2H.1.1-1 without taking into account the tolerance;
– MPR, AMPR is specified in clause 6.2H.1.2 and 6.2H.1.3;
The measured configured maximum output power PUMAX over all serving cells shall be within the following bounds:
PCMAX_L – MAX{TL, T LOW(PCMAX_L)} ≤ PUMAX ≤ PCMAX_H + T HIGH(PCMAX_H)
where TLOW(PCMAX_L) and THIGH(PCMAX_H) are defined as the tolerance and applies to PCMAX_L and PCMAX_H separately, while TL is the absolute value of the lower tolerance in Table 6.2 H.1.1-1 for the applicable operating band.
For UE supporting intra-band UL contiguous CA with UL MIMO, the tolerance is specified in Table 6.2H1..4-1.
