Abstract: Embodiments of the present disclosure relate to devices, methods, apparatuses and computer readable storage media for transferring traffic in integrated access and backhaul (IAB) communication. According to embodiments of the present disclosure, a first Central Unit-Control Plane (CU-CP) of a first IAB donor transmits, to a second CU-CP of a second IAB donor, a request to transfer target traffic via a Distributed Unit (DU) of the second IAB donor. The request comprises first information of the target traffic. The first CU-CP receives, from the second CU-CP, second information to be used for configuring the target traffic. This solution can improve the reliability and robustness of the IAB communication.
