6.2.2B UE maximum output power for UL-MIMO
36.1013GPPEvolved Universal Terrestrial Radio Access (E-UTRA)Release 18TSUser Equipment (UE) radio transmission and reception
For UE with two transmit antenna connectors in closed-loop spatial multiplexing scheme, the maximum output power for any transmission bandwidth within the channel bandwidth is specified in Table 6.2.2B-1. The requirements shall be met with the UL-MIMO configurations specified in Table 6.2.2B-2. For UE supporting UL-MIMO, the maximum output power is measured as the sum of the maximum output power at each UE antenna connector. The period of measurement shall be at least as defined in Table 6.2.2B-0.

NOTE 1: Void NOTE 2: 2 refers to the transmission bandwidths (Figure 5.6-1) confined within FUL_low and FUL_low + 4 MHz or FUL_high – 4 MHz and FUL_high, the maximum output power requirement is relaxed by reducing the lower tolerance limit by 1.5 dB NOTE 3: For the UE which supports both Band 11 and Band 21 operating frequencies, the tolerance is FFS. NOTE 4: PPowerClass is the maximum UE power specified without taking into account the tolerance NOTE 5: Void. |
||||||||
The default power class for an operating band is Power Class 3 unless otherwise stated.
For a power class 2 capable UE operating on Band 41, when an IE P-max as defined in TS 36.331 [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 41, the UE shall:
– if the UE supports a different power class than the UE default 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 as specified in sub-clause 6.2.5;
