Abstract: A technique of performing a handover procedure involves providing a proper timing adjustment indication for the UE performing RACH-less HO. Even though the discussion herein is on IAB scenarios and the idea takes an advantage of IAB nodes being in fixed locations (i.e., not moving in the network), it can be applied to UEs in general. The timing adjustment provided in performing a HO in an IAB network according to the improved techniques involves computing a timing advance (TA) to be used by an IAB node prior to executing HO to an alternative serving node. Such a use of a TA may enable a bypassing of a RACH procedure when accessing a cell.

Abstract: Disclosed are methods for. An example method may include: receiving, at a first apparatus, configuration information from a donor apparatus in an integrated access and backhaul network for a peer-to-peer connection between the first apparatus and a second apparatus via the integrated access and backhaul network; and transmit, at the first apparatus via an access link and to a third apparatus serving the first apparatus in the integrated access and backhaul network, a data unit of the peer-to-peer connection based on the configuration information. Related apparatuses and computer readable media are also disclosed.

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 methods, apparatuses and computer readable storage media for integrated access and backhaul (IAB) communication. According to embodiments of the present disclosure, a first IAB donor receives, from a second IAB donor, a reconfiguration message for a terminal device in a serving cell served by an IAB node. The IAB node migrates from a first cell in communication with the first IAB donor to a second cell in communication with the second IAB donor while keeping a cell identifier of the serving cell unchanged. The reconfiguration message indicates the terminal device to update a configuration for the second IAB donor. The first IAB donor ciphers the reconfiguration message based on a security parameter of the first IAB donor and provides the ciphered reconfiguration message to the IAB node. The solution enables physical cell identifiers of the cells provided by an IAB node to remain unchanged during the migration of the IAB node.

IPC: H04L1/18
Abstract: An IAB network node, part of a RAN in communication with a UE, performs the following: receiving configuration with information indicating which data is to be duplicated in a downlink direction and to be merged in an uplink direction; in the downlink direction, receiving first data over a backhaul link for a single DRB associated with the UE, determining the first data is indicated as data to be duplicated, duplicating the first data into multiple downlink traffic flows, and transmitting the multiple downlink traffic flows toward the UE; and in the uplink direction, receiving second data over multiple uplink traffic flows from the UE, determining the second data is indicated as data to be merged, merging the second data into a single traffic flow, and forwarding the single traffic flow toward the network over the backhaul link. Additional techniques use IAB DU and CU nodes.

Abstract: Embodiments of the present disclosure relate to methods, apparatuses and computer readable storage media for integrated access and backhaul (IAB) communication. According to embodiments of the present disclosure, an IAB node transmits, to an access and mobility management function (AMF), a registration request comprising information about the IAB node. The AMF transmits, to the IAB node, a message indicating a registration area and at least one allowed network slice for access by the IAB node. The registration area and the at least one allowed network slice are determined based on the information about the IAB node. The solution enables slice support information exchange and registration management for mobile IAB.

Abstract: Embodiments of the present disclosure relate to devices, methods, apparatuses and computer readable storage media for transferring traffic in integrated access and backhaul (IAB) communication. According to embodiments of the present disclosure, a first Central Unit-Control Plane (CU-CP) of a first IAB donor transmits, to a second CU-CP of a second IAB donor, a request to transfer target traffic via a Distributed Unit (DU) of the second IAB donor. The request comprises first information of the target traffic. The first CU-CP receives, from the second CU-CP, second information to be used for configuring the target traffic. This solution can improve the reliability and robustness of the IAB communication.

Abstract: In an embodiment, to reduce uplink reporting, a user equipment (UE) keeps a countof the number of uplink protocol data control packet (PDCP) service data units (SDUs) in a measurement period and a number of those uplink PDCP SDUs that either exceeded a configured delay threshold or were discarded without being sent. These numbers are processed by the UE into a single reporting metric which the UE reports to the network for example in a MDT measurement report. The network configures the delay threshold, which may be specific for a given QoS, and may also configure the measurement period.
