1. A digital unit (DU) in a wireless communication system, comprising:
a transceiver; and
at least one processor configured to:
generate at least one compressed symbol based on modulation compression using an in-phase data (I-data) and a quadrature-phase data (Q-data), and wherein each of the I-data and the Q-data is represented by at least one bit determined based on modulation order;
transmit, to a radio unit (RU) through a fronthaul, control information including:
position indication information for indicating a position of a first subcarrier signal transmitted in a physical resource block (PRB) to which the at least one compressed symbol is mapped, and
power indication information for indicating a transmit power of the first subcarrier signal associated with a scaler value for the modulation compression; and
transmit the at least one compressed symbol to the RU.
