A beamforming method in a simultaneous wireless information and power transfer system and an apparatus therefor may derive a transmission signal transmitted to a plurality of information users and a plurality of energy users from a base station having an N(here, Nis a natural number) number of antennas included in each cell, derive a SINR (Signal to Interference plus Noise Ratio) of an i(here, i is a natural number) information user by using a noise power of the i(here, i is a natural number) information user included in a m(here, m is a natural number) cell, derive a harvested power of a j(here, j is a natural number) energy user included in the m(here, m is a natural number) cell, and perform beamforming by using a transmission signal power at the base station and a total harvested power of the plurality of energy users receiving a transmission signal from the base station. Accordingly, it is possible to improve the effect of minimizing the transmission power of the base station and maximizing the harvested power of the energy users while satisfying the QoS (Quality of Service) and transmission power limitation of the information users.

Beamforming generation method in system for simultaneously transmitting wireless information and power, and recording medium and apparatus for performing same

The present invention relates to a method for selecting transmitting and receiving antennas in a full-duplex MIMO system based on channel information. An embodiment of the present invention provides a method for selecting antennas in a full-duplex MIMO wireless communication system for communication between a first node and a second node. The method may include: calculating the number of transmitting antennas and the number of receiving antennas at a node i having an Nnumber of antennas such that Nhas a maximum value, where Nrepresents the number of all possible antenna set candidates, N is a natural number of 2 or higher with Nbeing the sum of transmitting antennas and receiving antennas at said node i, and i is 1 or 2; and determining transmitting antennas and receiving antennas at node i in consideration of the transmission rate.
