A first user equipment (UE) device manages the cast type for transmissions to other UE devices within a group during handovers. At least two cast types can be used from a set of cast types that comprises groupcast and unicast although other cast types may be included.

Methods, apparatuses, and computer readable medium for enabling an efficient group handover mechanism that has less signaling overhead than single UE handover are provided. An example method at a base station includes transmitting a group handover request for the group of UEs to a target base station. The method further includes receiving a group handover acknowledgment from the target base station. The method further includes transmitting a group handover message to the group of UEs.

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.

A transmission configuration method includes: sending, by a first access network device, bearer-related information to a first terminal device. The bearer-related information is used to instruct the first terminal device to perform cooperative transmission with a second terminal device.

A group communications method and system, and a device are provided. The method includes: when a first terminal initiates access to a local area network group, obtaining, by a group management function network element, an identifier of a first user plane network element to be accessed by the first terminal, context information of the local area network group, and a first session port identifier; creating, for the local area network group, a rule group applied to a first session port, and creating or updating, for the local area network group based on the context information, a local area network group forwarding action rule (FAR) applied to the first user plane network element; and sending a first message to a session management network element, for configuring the rule group on the first session port, and configuring the local area network group FAR on the first user plane network element.

There is provided mechanisms for triggering mobility measurements. A method is performed by a network node. The method comprises obtaining information about backhaul link quality of a wireless backhaul link of the network node. The method comprises, as a result thereof, sending, to at least a subset of all UEs served by the network node in a cell, an indication for the subset of UEs to perform mobility measurements. The method comprises receiving mobility measurement reports from the subset of UEs. The method comprises determining a handover action for the subset of UEs based at least on the backhaul link quality and on the mobility measurement reports.

A circuit arrangement includes a preprocessing circuit configured to obtain context information related to a user location, a learning circuit configured to determine a predicted user movement based on context information related to a user location to obtain a predicted route and to determine predicted radio conditions along the predicted route, and a decision circuit configured to, based on the predicted radio conditions, identify one or more first areas expected to have a first type of radio conditions and one or more second areas expected to have a second type of radio conditions different from the first type of radio conditions and to control radio activity while traveling on the predicted route according to the one or more first areas and the one or more second areas.

The present disclosure relates to a method (30) relating to handover in a communication system (1). The method (30) comprises establishing (31) that a communication device (3) is involved in a handover process from a first cell(C1) to a second cell(C2); and increasing (33) transmission power of a scheduling assignment specific for the communication device (3). The disclosure also relates to a system, computer program and computer program products.

Antenna nodes are controlled to maintain a respective radio cell, each cell having one and the same physical cell identity. The antenna nodes are further controlled to maintain the respective radio cell in a single direction substantially along a path such that each wireless communication device, during movement in a movement direction along the path, can connect either to consecutive antenna nodes towards which the wireless communication device is moving or connect to consecutive antenna nodes away from which the wireless communication device is moving.

A first node sends, after determining that all data packets from a migrating IAB node are received, first indication information to a source IAB donor CU. The first node is an upstream IAB node of a source parent node of the migrating IAB node or is a source IAB donor DU, the source IAB donor CU is an IAB donor CU connected to the migrating IAB node before migration, and the source IAB donor DU is an IAB donor DU connected to the migrating IAB node before the migration. The first node receives second indication information from the source IAB donor CU. The first node updates or releases, based on the second indication information, backhaul configuration information that corresponds to the migrating IAB node and that is on a backhaul link between the first node and a child node of the first node.
