Method and apparatus for scheduling in a multi-input multi-output system

A method for operating a base station (BS), the method comprising:

• transmitting, to a first terminal, configuration information regarding a first beam group and regarding a second beam group;
• transmitting first signals transmitted using a first plurality of transmit (Tx) beams of the BS in the first beam group and second signals transmitted using a second plurality of Tx beams of the BS in the second beam group;
• receiving, from the first terminal, first information regarding at least one first Tx beam of the BS identified among the first plurality of Tx beams based on the first signals;
• and
• receiving, from the first terminal, second information regarding at least one second Tx beam of the BS identified among the second plurality of Tx beams based on the second signals.

An apparatus of a terminal, the apparatus comprising:

• at least one processor;
• and
• at least one transceiver,
• wherein the at least one transceiver is configured to:
• receive, from a base station (BS), configuration information regarding a first beam group and regarding a second beam group;
• receive, from the BS, first signals transmitted using a first plurality of transmit (Tx) beams of the BS in the first beam group and second signals transmitted using a second plurality of Tx beams of the BS in the second beam group;
• transmit, to the BS, first information regarding at least one first Tx beam of the BS identified among the first plurality of Tx beams based on the first signals, and
• transmit, to the BS, second information regarding at least one second Tx beam of the BS identified among the second plurality of Tx beams based on the second signals.
