摘要： An apparatus, comprising at least one processing circuitry, and at least one memory for storing instructions to be executed by the processing circuitry is disclosed. The at least one memory and the instructions are configured to, with the at least one processing circuitry, cause the apparatus at least, upon receipt of a deterministic data flow of data packets having a logical relation to each other, to identify the deterministic data flow based on a first control information provided at the apparatus. The apparatus is further at least caused to switch a forwarding status of the apparatus between a first status and a second status based on a second control information, and, in the first status, to decide whether to buffer or discard a data packet of the deterministic data flow of data packets based on a third control information.

摘要： 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.

摘要： 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.

摘要： 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: in accordance with a determination that a first terminal device and a first network device roams from a first network to a second network, transmitting a roaming indication to a second network device associated with the second network, the first terminal device and the first network device acting as an IAB node in the first network; causing the roaming of the first network device to be authorized by a third network device of the second network; and communicating in the second network via the first network device, the first network device operating based on parameters associated with the second network. As such, when an IAB node travels across different countries/regions, the service continuity, security, regulatory requirements associated with the IAB node can be guaranteed.

摘要： Embodiments of the present disclosure relate to devices, methods, apparatuses and computer readable storage media for integrated access and backhaul (IAB) communication. According to embodiments of the present disclosure, a first Donor-central unit (CU) from a first operator (which is a participating operator) obtains identification information concerning at least one of a second Donor-CU from a second operator (which is a hosting operator) and an IAB node from the second operator and shared for the first operator. The first Donor-CU determines an association of the shared IAB node to the second Donor-CU based on the obtained identification information. Based on the determined association, the first Donor-CU transmits to the second Donor-CU a request for configuring a channel towards to the shared IAB node. In this way, the IAB node of the second operator can be shared with the first operator and the first operator can operate cells and serve UEs via the IAB backhaul network of the second operator. This provides improved flexibility for sharing of IAB deployments and capital expenditure of the participating operator can be reduced.
