METHOD FOR BEAMFORMING Design IN Simultaneous WIRELESS INFORMATION AND POWER TRANSFER SYSTEM RECORDING MEDIUM AND APPARATUS FOR PERFORMING THE METHOD

摘要

The present invention relates to a method of generating beamforming in a system of simultaneously transmitting wireless information and power and an apparatus for performing the same. The method of generating beamforming in a system of simultaneously transmitting wireless information and power is capable of deriving a transmission signal to be transmitted to a plurality of information users and a plurality of energy users from a base station having N_r antennas (herein, N_r is a natural number), deriving a signal-to-interference-plus-noise ratio (SINR) of each i^th information user (herein, i is a natural number) by using noise power of the i^th information user (herein, i is a natural number) included in an m^th cell (herein, m is a natural number), deriving energy yield of a j^th energy user (herein, j is a natural number) included in an m^th cell (herein, m is a natural number), and generating beamforming by using the total energy yield of a plurality of energy users receiving transmission signal power from the base station and the transmission signal from the base station. Accordingly, it is possible to increase an effect of minimizing transmission power of the base station while satisfying quality of service (QoS) of the information users and transmission power limit and maximizing the energy yield of the energy users at the same time.
