6.2G Transmitter power for Tx Diversity

38.101-13GPPNRPart 1: Range 1 StandaloneRelease 17TSUser Equipment (UE) radio transmission and reception

6.2G.1 UE maximum output power for Tx Diversity

For UE supporting Tx Diversity, the maximum output power as indicated by UE power class in Table 6.2.1-1is defined as the sum of the maximum output power from both UE antenna connectors. The period of measurement shall be at least one sub frame (1 ms).

When a UE indicates PC1.5 for a given band it achieves maximum power by means of TxD in the current version of the spec.

6.2G.2 UE maximum output power reduction for Tx Diversity

For UE supporting Tx diversity, the allowed MPR for the maximum output power is specified in Table 6.2.2-1, Table 6.2D.2-1, Table 6.2D.2-2 and Table 6.2D.2-3 for UE power class 3, 2 and 1.5 respectively. For UE power class 1.5, the allowed maximum power reduction (MPR) defined in Table 6.2D.2-3 is in accordance with the indicated modifiedMPR-Behavior specified in Table L.1-1 for channel bandwidths ≤ 100 MHz. The maximum output power is defined as the sum of the maximum output power at each UE antenna connector. If a UE that supports PC1.5 has to apply the requirements of PC2 according to the rules in clause 6.2.1, the MPR requirements in Table 6.2.2-2 apply

6.2G.3 UE additional maximum output power reduction for Tx Diversity

For UE supporting Tx diversity, the A-MPR values specified in clause 6.2.3 shall apply to the maximum output power specified in Table 6.2.1-1, and the maximum output power is defined as the sum of the maximum output power at each UE antenna connector. Unless stated otherwise, an A-MPR of 0 dB shall be used.

6.2G.4 Configured transmitted power for Tx Diversity

For UE supporting Tx diversity, the transmitted power is configured per each UE.

The definitions of configured maximum output power P_CMAX,c, the lower bound P_{CMAX_L,c}, and the higher bound P_{CMAX_H,c} specified in clause 6.2.4 shall apply to UE supporting Tx diverstidy, where

– P_PowerClass, ΔP_PowerClass and ∆T_C,c are specified in clause 6.2.4 unless otherwise stated;

– MPR_c is specified in clause 6.2G.2;

The measured configured maximum output power P_UMAX,c for serving cell c shall be within the following bounds:

P_{CMAX_L,c} – MAX{T_L, T _LOW(P_{CMAX_L,c})} ≤ P_UMAX,c ≤ P_{CMAX_H,c} + T _HIGH(P_{CMAX_H,c})

where T_LOW(P_{CMAX_L,c}) and T_HIGH(P_{CMAX_H,c}) are defined as the tolerance and applies to P_{CMAX_L,c} and P_{CMAX_H,c} separately, while T_L is the absolute value of the lower tolerance in Table 6.2.1-1 for the applicable operating band.

For UE supporting Tx diversity, the tolerance is specified in Table 6.2G.4-1.
