6.2 Transmit power
25.1023GPPRelease 17TSUser Equipment (UE) radio transmission and reception (TDD)
6.2.1 User Equipment maximum output power
The nominal maximum output power defined is the broadband transmit power of the UE, i.e. the power in a bandwidth of at least (1+α) times the chip rate of the radio access mode. The period of measurement shall be a transmit timeslot excluding the guard period.
6.2.1.1 3.84 Mcps TDD option
The power classes in Table 6.1 define the nominal maximum output power for 3.84 Mcps TDD options.
Table 6.1: UE power classes
Power Class |
Nominal maximum output power |
Tolerance |
1 |
+30 dBm |
+1 dB / -3 dB |
2 |
+24 dBm |
+1 dB / -3 dB |
3 |
+21 dBm |
+2 dB / -2 dB |
4 |
+10 dBm |
+4 dB / -4 dB |
NOTE:
1) For multi-code operation the nominal maximum output power will be reduced by the difference of peak to average ratio between single and multi-code transmission.
2) The tolerance allowed for the nominal maximum power applies even at the multi code transmission mode.
3) For UE using directive antennas for transmission, a class dependent limit will be placed on the maximum EIRP (Equivalent Isotropic Radiated Power).
6.2.1.2 1.28 Mcps TDD option
The power classes in Table 6.2 define the nominal maximum output power for 1.28 Mcps TDD option. For MC-HSUPA, the nominal transmit power is defined by the sum of the broadband transmit power of each carrier in the UE.

NOTE 1: The tolerance allowed for the nominal maximum power applies even at the multi code transmission mode.
NOTE 2: For UE using directive antennas for transmission, a class dependent limit will be placed on the maximum EIRP (Equivalent Isotropic Radiated Power).
NOTE3: For multi-carrier transmission, the nominal maximum output power will be reduced by the corresponding cubic metric value.
6.2.1.3 7.68 Mcps TDD option
The power classes in Table 6.1 define the nominal maximum output power for 7.68 Mcps TDD options.
