摘要： 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.

摘要： Example embodiments of the present disclosure relate to a solution for handing over a group of devices. In an aspect, a first device transmits, to a second device, first information of a group of devices. The first device receives, from the second device, second information associated with a target handover configuration for the group of devices. The first device adjusts, based on the second information, a movement of the group of devices to enable the group of devices to be handed over based on the target handover configuration. With example embodiments of the present disclosure, a group of devices (such as, a swarm of UAVs) moving based on a movement pattern can be effectively and efficiently handed over from a serving cell to another serving cell, for example, in the UAV application scenario or the V2X application scenarios, or the like.
