Claim 7:
8. A method, comprising:
at a base station comprising a plurality of antennas, a data unit (DU), and a massive multiple-input multiple-output unit (MMU),
receiving, by the DU, a signal to be transmitted;
obtaining, by the DU, per-antenna-power-constraint (PAPC) information;
determining, by the DU, an estimated effective transmission power (Peff) based on the PAPC information;
pre-scheduling, by the DU, the signal for transmission based on the Peff,
receiving, by the MMU from the DU, the pre-scheduled signal;
performing, by the MMU, pre-coding on the pre-scheduled signal based on a current value of a PAPC determined at the MMU to normalize per-antenna gain of antennas of the plurality of antennas; and
providing, by the MMU, the pre-coded signal for transmission via the plurality of antennas.
