6.2.5B Configured transmitted power for UL-MIMO

36.1013GPPEvolved Universal Terrestrial Radio Access (E-UTRA)Release 18TSUser Equipment (UE) radio transmission and reception

For UE supporting UL-MIMO, 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 subclause 6.2.5 shall apply to UE supporting UL-MIMO, where

– P_PowerClass, ΔP_PowerClass and T_C,c are specified in subclause 6.2.2B;

– MPR_,c is specified in subclause 6.2.3B;

– A-MPR_,c is specified in subclause 6.2.4B.

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 6.2.2B-1 for the applicable operating band.

For UE with two transmit antenna connectors in closed-loop spatial amultiplexing scheme, the tolerance is specified in Table 6.2.5B-1. The requirements shall be met with UL-MIMO configurations specified in Table 6.2.2B-2.

Table 6.2.5B-1: P_CMAX,c tolerance in closed-loop spatial multiplexing scheme

PCMAX,c (dBm)	Tolerance TLOW(PCMAX_L,c) (dB)	Tolerance THIGH(PCMAX_H,c) (dB)
PCMAX,c =23	3.0	2.0
22 ≤ PCMAX,c < 23	5.0	2.0
21 ≤ PCMAX,c < 22	5.0	3.0
20 ≤ PCMAX,c < 21	6.0	4.0
16 ≤ PCMAX,c < 20	5.0
11 ≤ PCMAX,c < 16	6.0
-40 ≤ PCMAX,c < 11	7.0

If UE is configured for transmission on single-antenna port, the requirements in subclause 6.2.5 apply.
