Abstract: According to an embodiment, a method performed by a distributed unit (DU) may comprise generating, based on a modulation compression scheme, a modulation value corresponding to information bits. The method may comprise generating, based on a shifting operation corresponding to the modulation compression scheme, user plane (U-plane) data corresponding to the modulation value. The method may comprise transmitting, to a radio unit (RU) through a fronthaul interface, a U-plane message comprising the generated U-plane data. In a case of binary phase shift keying (BPSK), the modulation compression scheme may be set to perform the shifting operation based on a designated first equation. In a case of non-BPSK, the modulation compression scheme may be set to perform the shifting operation based on a designated second equation.
