Abstract: Embodiments of the present disclosure provide a method of communication in a base station (BS). The BS comprising a distributed unit (DU) and at least one radio unit (RU), said DU performs High-PHY processing and said RU performs low-PHY processing. The method comprises transmitting, by the DU, a control information to the at least one RU using at least one of a c-plane message and a m-plane message, and data using a u-plane message. The u-plane message is transmitted in one of a semi persistent and periodic technique. The transmitting of the at least one of a c-plane message and a m-plane message indicates the u-plane data as one of a semi persistent and a periodic, said transmitting is valid for the u-plane messages carrying the u-plane data for a predetermined time period.
