Assignee: SAMSUNG ELECTRONICS CO., LTD.
Field: Telecommunications (Electrical engineering)
Classification: CPC H | IPC H

Claim 0:
1. A base station comprising:
a plurality of antennas;
a data unit (DU) comprising a first processor and a first memory containing instructions, which when executed by the first processor, cause the DU to:
receive a signal to be transmitted;
obtain per-antenna-power-constraint (PAPC) information;
determine an estimated effective transmission power (Peff) based on the PAPC information; and
pre-schedule the signal for transmission based on the Peff, and

a massive multiple-input multiple-output unit (MMU) comprising a second processor and a second memory containing instructions, which when executed by the second processor, cause the MMU to:
receive, from the DU, the pre-scheduled signal;
perform 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 the pre-coded signal for transmission via the plurality of antennas.
