Provided is a method and apparatus for multi-antenna transmission to minimize a charging time of users in a wireless powered communication network. A power transmission apparatus may be configured to generate a covariance matrix to minimize a charging time of the power reception apparatus based on an amount of energy required by at least one power reception apparatus; to derive a beamforming vector using the covariance matrix; and to transmit a wireless power to the power reception apparatus based on the beamforming vector.

Method and apparatus for multi-antenna transmission to minimize charging time of users in wireless powered communication network

A receiver for transferring energy and data together and a signal processing method in the receiver are provided. The method includes decoding data included in a received signal using part of power received for charging a charging unit of the receiver with energy with respect to the signal for energy charging and data decoding, the signal being received from a transmitter.
