Apparatus and method for controlling power based on energy efficiency in multiple-input and multiple-output (MIMO) communication system

摘要

Provided is an apparatus and method for managing a power consumption of a transmitter based on energy efficiency in a multiple-input and multiple-output (MIMO) communication system. The transmitter is configured to control a power of at least one of a baseband (BB) component, a radio frequency (RF) chain component, and a power amplifier (PA) component based on calculation of the energy efficiency.
