    Abstract: A method for admission control including transmitting a first admission request to a distributed unit of the IAB donor, wherein the first admission request includes information about a resource set to be established for a terminal device; receiving a first admission response from the distributed unit indicating whether one or more resources in the resource set are to be accepted; transmitting a second admission request to each of at least one IAB node including information about the resource set; receiving a second admission response from each of the at least one IAB node indicating whether one or more resources in the resource set are to be accepted; and in response to determining that at least one resource in the resource set is to be accepted, transmitting to an IAB node serving the terminal device a request for establishing a context of the terminal device including information about the resource.

    Abstract: A base station serving UE(s) receives validity time information for cell(s) formed by other base station(s). The validity time information indicates at least a time period when corresponding cells are available for use by the UE(s). The base station determines action(s) to perform for the UE(s) based on the validity time information. A UE receives, from a base station, validity time for cell(s) formed by other base station(s). The UE performs action(s) based on the validity time of the cell(s).

    Abstract: Example embodiments of the present disclosure relate to devices, methods, apparatuses and computer readable storage media for enhancement on the IAB network. The method comprises: receiving, at a first network device and from a first central device for controlling the first network device, a first message comprising configuration information about at least one of duplication and de-duplication for a packet at backhaul adaptation protocol, BAP, layer; and communicating, based on the configuration information, the packet with a group of second network devices and the first central device in an integrated access and backhaul, IAB, network. By duplicating uplink and downlink data associated with terminal devices in the IAB network at BAP level, the reliability and resiliency of backhaul links can be improved.

    Abstract: Example embodiments of the present disclosure relate to devices, methods, apparatuses and computer readable storage media of signaling reduction at handover of an IAB node. The method including sending, from a first device to a second device, a request message for a handover from the first device to the second device for a third device, the request message including a first cell configuration of the third device associated with the first device; receiving, from the second device, a response message acknowledging to the request, the response message including a resource configuration for a connection between the third device and the second device and a second cell configuration of the third device associated with the second device and sending the resource configuration to the third device. In this way, the signal overhead for the handover of an IAB node may be reduced significantly.

    Abstract: A base station, in communication with a UE using a first serving cell, determines a need to perform a security update for the UE and sends a command including information to perform the security update and indication of a time to execute the security update to change to a new security configuration. In response to the time occurring, a security update is performed to a new security configuration for use for communication with the UE using a second serving cell. The UE receives the information and the indication and performs, without performing a random-access procedure, the security update to the new security configuration to use for communication with the second serving cell.

    Abstract: Example embodiments of the present disclosure relate to handover for a device (s) served by an Integrated Access and Backhaul (IAB) node. A first device receives indication information indicating a change of service availability of a second device that serves at least one third device. The first device determines, based on the indication information, whether a handover of the at least one third device from the second device is to be triggered. In accordance with a determination that the handover of the at least one third device is to be triggered, the first device transmits, to the second device, handover information indicating at least one fourth device selected for the handover of the at least one third device from the second device.

    Abstract: Embodiments of the present disclosure relate to devices, methods, apparatuses and computer readable storage media of resource pool configuration and usage for V2X. The method comprises receiving, at a first device, information of a set of resource pools allocated for a predetermined area from a second device and a usage pattern for the set of resource pools from a third device, the usage pattern at least indicating an association between the set of resource pools and at least one property of the predetermined area. The method further comprises determining at least one attribute of the first device related to the at least one property and determining a target resource pool for communication from the set of resource pools based on the at least one attribute, the information and the usage pattern. In the solution, the V2X control device may coordinate the resource pool configuration with the network device and determine polices for the usage of the resource pool. In this way, the resource pool can be configured more efficient for V2X packet distribution and reception.
