Section: 6.2.3 UE maximum output power for modulation / channel bandwidth
Content: For UE Power Class 1, 2 and 3, the allowed Maximum Power Reduction (MPR) for the maximum output power in Table 6.2.2-1due to higher order modulation and transmit bandwidth configuration (resource blocks) is specified in Table 6.2.3-1. Table 6.2.3-1: Maximum Power Reduction (MPR) for Power Class 1, 2 and 3 For PRACH, PUCCH and SRS transmissions, the allowed MPR is according to that specified for PUSCH QPSK modulation for the corresponding transmission bandwidth. For each TTI pattern, the MPR shall be evaluated per Teval period as specified in table 6.2.3-2 and given by the maximum value taken over the transmission(s) within that period; the maximum MPR over TREF is then applied for TREF. Table 6.2.3-2: MPR evaluation period For UE Power Class 1 and 3 transmissions with non-contiguous resource allocation in single component carrier, the allowed Maximum Power Reduction (MPR) for the maximum output power in table 6.2.2-1, is specified as follows MPR = CEIL {MA, 0.5} Where MA is defined as follows for QPSK, 16 QAM and 64 QAM MA = 8.00-10.12A ; 0.00< A ≤ 0.33 5.67 - 3.07A ; 0.33< A ≤0.77 3.31 ; 0.77< A ≤1.00 Where MA is defined as follows for 256 QAM MA = 8.00-10.12A ; 0.00< A ≤ 0.25 5.50 ; 0.25< A < 1.00 Where A = NRB_alloc / NRB. CEIL{MA, 0.5} means rounding upwards to closest 0.5dB, i.e. MPR [3.0, 3.5 4.0 4.5 5.0 5.5 6.0 6.5 7.0 7.5 8.0] The allowed MPR for transmission on an Scell in Band 46 or Band 49 within a component carrier of a nominal channel bandwidth of 10 MHz or 20 MHz is in accordance with 6.2.3-1 for RIV = ‘11111’ (10 MHz) and L = 10 (20 MHz) with L defined in Clause 8.1.4 of [6]. For all other possible values of the RIV defined in Clause 8.1.4 of [6] the allowed MPR is 2.5 dB for QPSK modulation, 3 dB for 16QAM modulation and 4 dB for 64QAM modulation (256QAM is FFS). For a power class 2 capable UE operating on Band 41, when an IE P-max as defined in [7] of 23 dBm or lower is indicated in the cell or if the uplink/downlink configuration is 0 or 6, the requirements for power class 2 are not applicable, and the corresponding requirements for a power class 3 UE shall apply. For each supported frequency band other than Band 14 and Band 41, the UE shall: - if the UE supports a different power class than the default UE power class for the band and the supported power class enables the higher maximum output power than that of the default power class: - if the band is a TDD band whose frame configuration is 0 or 6; or - if the IE P-Max as defined in TS 36.331[ Evolved Universal Terrestrial Radio Access (E-UTRA); Radio Resource Control (RRC); Protocol specification ]  [7] is not provided; or - if the IE P-Max as defined in TS 36.331[ Evolved Universal Terrestrial Radio Access (E-UTRA); Radio Resource Control (RRC); Protocol specification ]  [7] is provided and set to the maximum output power of the default power class or lower; - meet all requirements for the default power class of the operating band in which the UE is operating and set its configured transmitted power as specified in sub-clause 6.2.5; - else (i.e the IE P-Max as defined in TS 36.331[ Evolved Universal Terrestrial Radio Access (E-UTRA); Radio Resource Control (RRC); Protocol specification ]  [7] is provided and set to the higher value than the maximum output power of the default power class): - meet all requirements for the supported power class and set its configured transmitted power class as specified in sub-clause 6.2.5. For UE Power Class 2 transmissions with non-contiguous resource allocation in single component carrier, the allowed Maximum Power Reduction (MPR) for the maximum output power is not specified in this version of the specification. For the UE maximum output power modified by MPR, the power limits specified in subclause 6.2.5 apply.
