Precoding information signaling method and apparatus for uplink transmission in mobile communication system using a plurality of array antennas

A terminal in a wireless communication system, the terminal comprising:

• a transceiver;
• and
• a controller configured to control the transceiver to receive, from a base station, precoding-related information for uplink by the terminal, identify whether uplink subband precoding is applicable based on the precoding-related information, and control the transceiver to perform uplink transmission based on specific subband precoding information, according to the uplink subband precoding being identified to be applicable.

A base station in a wireless communication system, the base station comprising:

• a transceiver;
• and
• a controller configured to identify whether to allow uplink subband precoding of a terminal based on a channel status of uplink by the terminal, control the transceiver to transmit, to the terminal, precoding-related information including a result of the identification, and control the transceiver to receive, from the terminal, uplink resources based on the transmission of the precoding-related information.
