A method of performing radio link recovery between a first and second wireless device in a sidelink multi-hop network, the method including: at a third wireless device: receiving a communication resume request message from the first wireless device; relaying the communication resume request message received from the first wireless device; receiving, from the second wireless device that received the relayed communication resume request message, a communication resume confirmation message; and relaying the communication resume confirmation message from the second device to the first device to establish a multi-hop connection between the first device and the second device via the third device.

The embodiments of the present application relate to the technical field of wireless communications, and provide a device-to-device relay processing method, device and apparatus, and a storage medium, which are used for implementing an activation or deactivation function of the device-to-device relay. Said method comprises: according to channel quality information of a direct link between a first device and at least two second devices, the first device determining a processing manner of the first device for a device-to-device relay function, the processing manner comprising activating the device-to-device relay function or deactivating the device-to-device relay function.

A communication method and an apparatus. The method includes: receiving at least one piece of quality of service QoS information from a second terminal; determining first QoS information based on the at least one piece of QoS information; and determining a first bearer configuration based on the first QoS information, and forwarding data from the second terminal to a third terminal based on the first bearer configuration; or sending the first QoS information to a network device, receiving a first bearer configuration of the network device, and forwarding data from the second terminal to a third terminal based on the first bearer configuration.

Provided are a QoS control method and apparatus, and a readable storage medium. A source UE sends request information to a target UE according to the triggering of an application, wherein the request information comprises QoS information of service data that is transmitted between the source UE and the target UE; and when receiving the request information issued by the source UE to the target UE, a relay UE can obtain QoS information of the service data that is transmitted between the source UE and the relay UE, and QoS information of the service data that is transmitted between the relay UE and the target UE.

A configuration method for a sidelink relay architecture and a device are disclosed. The method is executed by a relay terminal, and includes: receiving configuration information, where the configuration information is used for configuring a mapping relationship between a universal user network interface Uu bearer and at least one of the following of a remote terminal: a sidelink bearer or quality of service QoS flow information, and the Uu bearer is a bearer between the relay terminal and a network device.

Certain aspects of the present disclosure provide techniques for wireless communications by a mobile repeater. The mobile repeater measures broadcast signals from one or more target cells as the mobile repeater moves through a network. The mobile repeater selects one of the target cells, based on the measuring and side information. The mobile repeater forwards signals between a user equipment (UE) and the selected target cell.

A method and device are disclosed for radio resource allocation to support User Equipment-to-Network (UE-to-Network) relaying. The network node establishes a Radio Resource Control (RRC) connection with a remote UE via a relay UE. The network node transmits a first RRC message to the remote UE via the relay UE, wherein the first RRC message includes a Uu radio bearer configuration and a Sidelink (SL) Radio Link Control (RLC) bearer configuration associated with a data radio bearer (DRB) or a signalling radio bearer (SRB) and wherein the network node is allowed to include a first field used to indicate a configuration for UE autonomous resource selection for sidelink communication transmission in the first RRC message and the network node is not allowed to include a second field used to indicate a configuration for UE to transmit sidelink communication based on network scheduling in the first RRC message.

Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a relay user equipment (UE) may receive, from a base station, a downlink control information (DCI) message scheduling a first transmission between a source node and the relay UE and a second transmission between the relay UE and a destination node. The UE may transmit, to the base station, at least one of: feedback regarding at least one of the first transmission or the second transmission, or the second transmission. Numerous other aspects are described.

A configuration utilising L1/L2 signaling to activate or deactivate a direct link in dual or multi-connectivity with relaying devices. The apparatus communicates with a base station using a direct link and using a relay link. The relay link comprises a side link between a first UE and a second UE and a second direct link between the second UE and the base station. The apparatus transmits or receives a request to deactivate the direct link based on a determination by at least one of the base station, the first UE, or the second UE that the direct link between the first UE and the base station is to be deactivated. The request to deactivate the direct link comprises L1 or L2 signaling. The apparatus receives a deactivation command to deactivate the direct link.

Methods, systems, and devices for wireless communications are described. A first wireless node may transmit, to a control node, an indication of a capability of the first wireless node to perform one or more self-interference cancelation (SIC) procedures between a first antenna array of the first wireless node and a second antenna array of the first wireless node. The first wireless node may receive, from the control node in response to the indication of the capability, a configuration for the first wireless node to use to perform a SIC procedure of the one or more SIC procedures for full-duplex communications. The first wireless node may then communicate, according to the received configuration, with the control node, a control node, or any combination thereof, using the first antenna array and the second antenna array.
