Apparatus and methods for better estimation of radiation power utilizing PAPC compensation

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.

A non-transitory computer-readable medium containing instructions, which, when executed by a processor, cause a base station, which includes a plurality of antennas, a data unit (DU) and a massive multiple-input multiple-output unit (MMU), to:

• receive, by the DU, a signal to be transmitted via the plurality of antennas;
• obtain, by the DU, per-antenna-power-constraint (PAPC) information;
• determine, by the DU, an estimated effective transmission power (Peff) based on the PAPC information;
• pre-schedule, by the DU, the signal for transmission based on the Peff,
• receive, by the MMU from the DU, the pre-scheduled signal;
• perform, 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
• provide, by the MMU, the pre-coded signal for transmission via the plurality of antennas.
