Abstract

Methods are provided for selecting a multiple-input multiple-output (MIMO) mode based on energy efficiency and selecting a subset of antennas to be used in communication in a wireless communication system using multi-user massive multiple antennas. The method selects a subset of antennas that minimizes the transmission power without using all antennas based on power consumption and transmission power caused by radio frequency (RF) circuits. The method also includes selecting a mobile station to which a signal is to be transmitted, selecting a multi-antenna technique based on power consumption of all antennas, selecting a subset of antennas among all antennas to transmit a signal to the mobile station, and transmitting a signal to the mobile station by using the antenna subset .

Description

technical field [0001] The present disclosure relates to devices and methods for improving the energy efficiency of base stations in wireless communication systems. More particularly, the present disclosure relates to a signal transmission technique for selecting an antenna pattern that improves energy efficiency of a base station in a wireless communication system using a multi-user massive multi-antenna, and selecting a subset of antennas among all antennas that transmits a signal to a mobile station . Background technique [0002] Wireless data traffic has exploded due to the incentives of wireless multimedia services and social networking services (SNS) with the spread of smart phone usage and the growth of wireless demand (eg, machine-to-machine communication). Therefore, a big data environment that is not easily handled by the data transfer method of the related field is coming. [0003] With the advent of the big data environment, massive multiple-input multiple-out...
