Abstract: Disclosed are methods for controlling message transmissions in an integrated access and backhaul network. An example method may include: determining, by a donor central unit in an integrated access and backhaul network, at least one configuration for controlling a transmission of at least one radio resource control message from a node to a child node of the node in the integrated access and backhaul network: and transmitting, by the donor central unit the at least one configuration to the node. Related apparatuses and computer readable media are also disclosed.

Abstract: Embodiments of the disclosure provide a method, device and computer readable medium for centralized unit switch. According to embodiments of the present disclosure, the DU transmits identity information of a target CU/DU to the source CU for the CU switch. The target CU does not need to initiate context setup procedure to set up context for the terminal device. Thus, the switch is implemented with minimized signaling and interruption in the data connection and the switched is completed faster by avoiding the unnecessary F1 AP context setup.
