Effective scheduling of terminals in a wireless communication system

A scheduling method performed by a base station apparatus including a processor and a plurality of antennas, the scheduling method comprising:

• transmitting, by the plurality of antennas, to each of a plurality of terminal apparatuses, first and second wireless signals to form first and second beams, respectively, and receiving, from each terminal apparatus, a third wireless signal including feedback information of the terminal apparatus in response to the second wireless signal;
• selecting, by the processor, from among the plurality of terminal apparatuses, based on the feedback information and a correlation value between the first beam and the second beam, a terminal apparatus to which the second beam is optimum, as a first terminal apparatus that performs communication via the first beam, or a terminal apparatus as a second terminal apparatus that performs communication via the second beam while communication via the first beam is performed in parallel;
• and
• transmitting, by the plurality of antennas, a fourth wireless signal including data to each terminal apparatus to form the first beam or the second beam.

A wireless communication system comprising:

• a base station apparatus including a first processor and a plurality of antennas;
• and
• a plurality of terminal apparatuses each including a second processor, wherein:
• the plurality of antennas is configured to:
• transmit, to each of the plurality of terminal apparatuses, first and second wireless signals to form first and second beams, respectively, and
• receive, from each terminal apparatus, a third wireless signal including feedback information of the terminal apparatus in response to the second wireless signal;
• the first processor selects, from among the plurality of terminal apparatuses, based on the feedback information and a correlation value between the first beam and the second beam, a terminal apparatus to which the second beam is optimum, as a first terminal apparatus that performs communication via the first beam, or selects a terminal apparatus as a second terminal apparatus that performs communication via the second beam while communication via the first beam is performed in parallel;
• and
• the plurality of antennas transmit a fourth wireless signal including data to each terminal apparatus to form the first beam or the second beam.
