6.2.3D UE maximum output power for modulation / channel bandwidth for ProSe
36.1013GPPEvolved Universal Terrestrial Radio Access (E-UTRA)Release 18TSUser Equipment (UE) radio transmission and reception
When UE is configured for E-UTRA ProSe sidelink transmissions non-concurrent with E-UTRA uplink transmissions for E-UTRA ProSe operating bands specified in Table 5.5D-1, this subclause specifies the allowed Maximum Power Reduction (MPR) power for ProSe physical channels and signals due to higher order modulation and transmit bandwidth configuration (resource blocks).
The allowed MPR for the maximum output power for ProSe physical channels PSDCH, PSCCH, PSSCH, and PSBCH shall be as specified in subclause 6.2.3 for PUSCH for the corresponding modulation and transmission bandwidth.
The allowed MPR for the maximum output power for ProSe physical signal PSSS shall be as be as specified in subclause 6.2.3 for PUSCH QPSK modulation for the corresponding transmission bandwidth.
The allowed MPR for the maximum output power for ProSe physical signal SSSS is specified in Table 6.2.3D-1.
For a power class 2 capable UE operating on Band 41, the corresponding requirements for a power class 3 UE apply 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.
For each supported frequency band other than 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 [7] is not provided; or
– if the IE P-Max as defined in TS 36.331 [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 [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.

When UE is configured for simultaneous E-UTRA ProSe sidelink and E-UTRA uplink transmissions for inter-band E-UTRA ProSe / E-UTRA bands specified in Table 5.5D-2, the requirements in subclause 6.2.3D apply for ProSe transmission and the requirements in subclause 6.2.3 apply for uplink transmission.
