19. A user equipment (UE), comprising:
an antenna panel having two transmission polarization circuitries each having one or more antenna; and
baseband circuitry configured to independently feed two independent transmission (TX) streams to the transmission polarization circuitries, calculate transmission power for the two Tx streams separately and apply a 3 dB down-scaling of a maximal transmission power limit for each calculated transmission power,
wherein the antenna panel is configured to form two different transmission beam patterns each directed to a different base station.
