Section: 6.2.4G UE maximum output power with additional requirements for V2X Communication
Content: For QPSK the MPR requirements specified in subclause 6.2.3G does not apply, i.e. MPR = 0dB. For 16QAM and 64 QAM, the applied maximum output power reduction is obtained by taking the maximum value of MPR requirements specified in subclause 6.2.3G and A-MPR requirements specified in subclause 6.2.4G. When UE is configured for E-UTRA V2X sidelink transmissions non-concurrent with E-UTRA uplink transmissions for E-UTRA V2X operating bands specified in Table 5.5G-1, the maximum output power reduction specified as A-MPR = CEIL {MA, 0.5} Where MA is defined as follows MA = A-MPRBase + Gpost connector * A-MPRStep CEIL{MA, 0.5} means rounding upwards to closest 0.5dB. A-MPRBase and A-MPRStep are specified in Tables 6.2.4G-1, 6.2.4G-2, 6.2.4G-3 is allowed when network signalling value is provided. The supported post antenna connector gain Gpost connector is declared by the UE following the principle described in annex I. NOTE: the A-MPRstep is the increase in A-MPR allowance to allow UE to meet tighter conducted A-SE and A-SEM requirements with higher value of declared Gpost connector. A-MPRBase is the default A-MPR value when no Gpost connector is declared. A-MPRBase and A-MPRstep vary depending on channel frequency and RB allocation. For channel frequencies and RB allocations that are close to the frequency range 5815-5855MHz, those value are much higher due to stringent emission requirement in this range. Table 6.2.4G-1: Additional Maximum Power Reduction (A-MPR) for power class 3 V2X UE Table 6.2.4G-2: A-MPR for NS_33 The allowed A-MPR for the maximum output power for V2X physical signal PSBCH and PSSS/SSSS shall be as be as specified in subclause 6.2.4 for the corresponding modulation and transmission bandwidth. When UE is configured for simultaneous E-UTRA V2X sidelink and E-UTRA uplink transmissions for inter-band E-UTRA V2X / E-UTRA bands specified in Table 5.5G-2, the requirements in subclause 6.2.4G apply for V2X PSSCH and PSCCH transmission. The allowed A-MPR requirements in subclause 6.2.4D apply for other V2X sidelink transmission (PSBCH/PSSS/SSSS). The A-MPR requirements in subclause 6.2.4 apply for uplink transmission. When UE is configured for E-UTRA V2X sidelink transmissions non-concurrent with E-UTRA uplink transmissions for E-UTRA V2X operating bands specified in Table 5.5G-1, the allowed A-MPR for the maximum output power for V2X physical channels PSCCH and PSSCH shall be as specified in Table 6.2.4G-3 and 6.2.4G-4 for V2X UE power class 2.
