Abstract: This disclosure relates to methods and devices for wireless sidelink resource allocation for a user equipment (UE) assisted by an anchor UE. Various mechanisms are disclosed for handling releasing of the anchor UE initiated by either the anchor UE or the assisted UE, and for handling sidelink resources already allocated to the UE by the anchor UE prior to the release. Additional mechanisms are disclosed for using an anchor UE to assist in allocating sidelink resources to multiple UEs configurable in a shared manner or non-shared manner.

Abstract: The present disclosure describes methods, systems, and devices for informing at least one downstream device of a migrating integrated access backhaul node (IAB-node) about an inter-donor migration status of migrating IAB node undergoing a migration from a source IAB-donor to a target IAB-donor. The method includes receiving, by a receiving device, a radio resource control (RRC) message sent from an IAB-donor. The RRC message includes an information element which indicates an inter-donor migration status of a migrating IAB-node. The method further includes in response to the information element indicating a successful inter-donor migration, sending, by the receiving device, a packet data convergence protocol (PDCP) status reports to a target IAB-donor. The PDCP status report corresponds to a radio link control acknowledged mode (RLC-AM) bearer configured to be allowed to send the PDCP status report in an uplink, and is configured to update data transmission for the receiving device.

Abstract: The present disclosure describes methods, systems, and devices for updating configuration information for a migrating integrated access backhaul node (IAB-node) during an inter-donor migration from a source IAB-donor to a target IAB-donor. One method includes providing, by a target IAB-donor central unit (CU), configuration information for a migrating IAB-node distributed unit (DU) in a dedicated radio resource control (RRC) message during handover preparation. The method further includes sending, by the target IAB-donor CU, a XnAP message to a source IAB-donor CU, the XnAP message comprising the configuration information as an RRC transparent container, and then the source IAB-donor CU sends the dedicated RRC message to a migrating IAB-node mobile termination (MT), the dedicated RRC message comprising the configuration information.

Abstract: Provided are a data transmission method and apparatus and a storage medium. The method includes: in a case where a user equipment (UE) determines that the UE is incapable of simultaneously transmitting uplink (UL) traffic and sidelink (SL) traffic, comparing a priority of a UL channel with a priority of an SL channel, and transmitting traffic according to a comparison result.

Abstract: Provided are a method and device for determining a transmission mode, a storage medium and an electronic device. The method includes acquiring information for determining the transmission mode, where the information includes at least one of: service profile information about a first service from an upper layer of a first terminal or an application layer of the first terminal, access layer information about the first terminal, transmission parameter information configured for the first terminal by a base station, or capability information about a second terminal of a proximity service; and determining the transmission mode according to the information. This can solve the problem in the existing art of how to perform communication better when there are UEs of different types or different capabilities in a system.
