transmitting control information, by a distributed unit (DU), to a radio unit (RU) using a control message;
transmitting u-plane data, by the DU, to the RU using a u-plane message;
receiving the u-plane message, by the RU, according to a semi persistent technique or a periodic technique,
wherein the control message comprises a c-plane message or an m-plane message, wherein the control message comprises an indication to use the semi persistent technique or the periodic technique to receive the u-plane message, and
the indication is valid to be used by the RU to receive: the u-plane message carrying the u-plane data; and at least one u-plane message subsequently received by the RU, for a predetermined time period as indicated by the control message.
