Abstract
A radio communication system of an example includes: a first radio base station which includes an antenna including antenna elements, and configured to transmit signals from the antenna elements; and user equipment. The user equipment selects a desired signal for the user equipment by taking into account reception characteristics of the respective signals transmitted by the radio base station, and transmits a signal selection indicator to the radio base station. Based on the signal selection indicator, the radio base station determines an antenna element to transmit a signal for communications with the user equipment, and transmits a data signal precoded using a predetermined precoding vector to the user equipment.
