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

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 for topology redundancy. A first device transmits to a second device a request for setup of a context of a third device served by the first device. The first device receives the context from the second device. The first device transmits the context to the third device for communication between the third device and the first device via a fourth device. The fourth device is managed by the second device.

Devices, methods, apparatuses and computer readable media for topology redundancy

There are provided measures for enabling/realizing flexible and adaptive QoS monitoring for unicast/groupcast over sidelink communication, which may preferably be capable of enhancing support of unicast/groupcast services over sidelink communication. Such measures exemplarily comprise obtaining a request for QoS monitoring for unicast/groupcast over sidelink communication with a specified quality-of-service profile, which indicates at least one target QoS metric to be monitored, determining a QoS monitoring procedure, wherein a scheme for enforcing QoS monitoring over sidelink communication in collaboration with at least one unicast/groupcast receiving-side device is decided, and performing the QoS monitoring procedure, wherein QoS monitoring messages are exchanged with the at least one unicast/groupcast receiving-side device over the sidelink communication with the specified QoS profile in accordance with the decided scheme and the at least one target quality-of-service metric is derived based thereon.

QoS monitoring for unicast/ groupcast over sidelink communication

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.

It is provided a method, comprising monitoring if a request for a handover of a platoon leader from a source cell to a target cell is received, wherein the request for the handover comprises a description of the required resources for platoon leader and all platoon members; and the method further comprises configuring the platoon leader and the platoon members with a new resource allocation if the request for the handover is received; informing the source cell on the new resource allocation and reserving or pre-reserving the resources in at least one of the source and target cell; supervising if the trigger event has occurred; activating the new resource allocation in the platoon leader and the platoon members if the activation command is received.

The invention is directed at a method of distributing system information to one or more mobile terminals in a cellular telecommunications network. The network comprises at least one signaling cell serving a first coverage area, and one or more data cells associated with said signaling cell, each one of said data cells serving a respective partial coverage area covering at least a part of the first coverage area. For each one of said data cells, the respective data cell is operated in either an active or inactive communication mode depending on whether there is at least one of said mobile terminals present in the partial coverage area of said respective data cell, and whether said at least one mobile terminal operates in an active terminal mode and is not served by other data cells.

In a method for transmitting data through a Massive MIMO backhaul system, a central node of the MIMO backhaul system transmits, to a small cell repeater terminal on the downlink, a downlink pilot signal carrying a set of pilot sequences that are mutually orthogonal in the frequency domain. Each pilot sequence in the set of pilot sequences corresponds to an antenna of an antenna array at the central node. The central node receives an uplink pilot signal carrying the set of pilot sequences transmitted by the small cell repeater terminal on the uplink, where the received uplink pilot signal is a frequency converted retransmission of the downlink pilot signal. The central node estimates at least one of an uplink channel and a downlink channel between the central node and the small cell repeater terminal based on the set of pilot sequences and the received uplink pilot signal.

A method for handover of a mobile node (MN) in a communications network from a previous point of attachment (p-PoA) associated with a previous mobility access gateway (pMAG) to a new point of attachment (n-PoA) associated with a new mobility access gateway (nMAG), where the pMAG and nMAG are associated with a mobility anchor (LMA), comprises the nMAG receiving a handover indicator concerning the MN from the pMAG. After receiving the handover indicator at the nMAG, the nMAG establishes a transient binding with the LMA. Following establishment of the transient binding, the nMAG receives downloaded data for the MN from the LMA prior to establishment of a connection between the MN and the n-PoA. The method may be used with PMIP Mobile Internet Protocol (PMIP).

The construction of directional couplers according to the invention with the aid of integrated optical waveguides makes it possible to produce such directional couplers in series very compactly and relatively easily. In this connection, the integrated optical waveguides in the coupling region have a smaller cross section than the cross section outside the coupling region. Consequently, it is possible to keep the spacing of the waveguide segments in the coupling region of a directional coupler according to the invention sufficiently far away from one another to minimize the error tolerance conditions in the manufacturing process. This is particularly advantageous if the difference in the refractive indices between the core of the integrated optical waveguide and its surroundings is very large.
