Abstract
A base station (BS) and a method of operating the BS. The BS comprises a distributed unit (DU) and a radio unit (RU). The DU is configured to transmit control information to the RU using a control message. The DU is configured to transmit u-plane data to the RU using a u-plane message. The RU is configured to receive the u-plane message according to a semi persistent technique or a periodic technique. The control message comprises a c-plane message or an m-plane message. The control message comprises an indication to use the semi persistent technique or the periodic technique to receive the u-plane message. 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.
