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.

Handover for a device served by an IAB node

A method, apparatus, and a computer-readable storage medium are provided for joint management of resources of vehicle-to-everything (V2X) communications. In one example implementation, the method may include notifying, by a first user equipment (UE), one or more second user equipments (UEs) about a first group of resources selected for sidelink communications. The first user equipment (UE) and the one or more second user equipments (UEs) belong to a group of user equipments (UEs) with the first user equipment (UE) as a lead user equipment (UE) of the group of user equipments (UEs). The example method may further include receiving, by the first user equipment (UE), feedback from the one or more second user equipments (UEs); and determining, by the first user equipment, a second group of resources for sidelink communications of the group of user equipments (UEs), the second group of resources being determined based at least on the feedback received from the one or more second user equipments (UEs).

Coordination of sidelink mode-2 resource reservation for V2X communications

For a UE in a wireless network and able to communicate via sidelink communications with other UE(s), the UE determines whether a specific condition exists indicating the UE has limited availability of CG resources used to communicate for the sidelink communications. The UE sends, using the sidelink communications, a message indicating the limited availability of the CG resources toward the other UE(s). Another UE receives the message indicating a limited availability of CG resources for the UE, and prepares an application in the other UE for a less sensitive mode of operation having less QoS than a mode having a normal QoS. A base station can configure the UE with the CG resources and provide a set of parameters to the UE to be used to form the message for the user equipment to transmit to the other UE(s) using sidelink communications.

Sidelink advanced notification

Embodiments of the present disclosure relate to devices, methods, apparatuses and computer readable storage media of a proactive switch of vehicle-to-everything communication from a device-to-device connection to a connection routed by one or more network devices. In example embodiments, a first terminal device receives, from a second terminal device via a device-to-device connection, an indication of a decision to switch the device-to-device connection to a connection routed by at least one network device for communication with the second terminal device. Based on the received indication from the second terminal device, the first terminal device then determines proactive switching from the device-to-device connection to the routed connection to be performed. The first terminal device then sends a request to a first network device of the at least one network device to set up the routed connection, the request indicating a cause for the determined proactive switching.

The present invention provides apparatuses, methods, systems, computer programs, computer program products and computer-readable media for reducing overhead for Quality-of-service (QoS) monitoring of vehicle-to-everything (V2X) services. The method comprises receiving, at a user equipment, from a serving network, a request for a Quality-of-Service (QoS) monitoring session, making a first determination, at the user equipment, whether the user equipment is relevant for the request, based on the content of the request, making a second determination, at the user equipment, if it is determined in the first determination that the user equipment is relevant, whether the request is received in dedicated signaling or common signaling, deciding, at the user equipment, whether or not to initiate the requested QoS monitoring session based on the second determination.
