A relay user equipment (UE) configured to operate as a relay between a remote UE and a network component performs a method. The method includes determining at least one relay capability of the relay UE and performing a relay access control operation that indicates to the remote UE whether the remote UE is permitted to use the relay UE as the relay.

This application provides a resource configuration method and a communication apparatus. In the technical solutions of this application, a donor node may configure different DU resource configurations for an IAB node and two parent nodes of the IAB, so that the IAB node can determine MT resources for different parent nodes based on the different DU resource configurations, to implement resource configuration of the IAB node in a dual connectivity scenario.

A method for configuring a wireless communication coverage extension system is described. The latter comprises a backhaul subnetwork in tree form comprising a plurality of interconnected nodes. At least two nodes directly connected to an internet access gateway are identified among the nodes of the backhaul subnetwork. A single node is selected from the at least two identified nodes to be the node through which a configuration of the wireless communication coverage extension system is defined. The configuration of the wireless communication coverage extension system defined is then sent from the selected node to all the other nodes of the backhaul subnetwork.

A method for transferring a message in a communications network for communication between a road user and at least one further road user. The road user and the further road user each include an evaluation unit for transferring messages via the communications network. The method includes: receiving a first message in the evaluation unit, the first message including message segments, each including a priority value; determining an instantaneous capacity utilization of the communications network; filtering message segments to be transferred out of the first message, based on the priority values and the instantaneous capacity utilization of the communications network; and generating a second message including the message segments to be transferred, and sending the second message via the communications network.

The present technology relates to a wireless communication terminal and a wireless communication method that make it possible to execute coordinated transmission via a desired access point. The wireless communication terminal starts setting up the coordinated transmission in order to cause a plurality of wireless communication apparatuses to execute the coordinated transmission. The present technology is applicable to a wireless communication system.

A communication control method includes, by a relay node relaying communication between a lower node and an upper node, detecting a failure in a first radio link between the upper node and the relay node, by the relay node, in response to the detection of the failure, transmitting, to the lower node, a first notification indicating the detection of the failure and attempting recovery of the first radio link, and, by the lower node, executing predetermined processing in a state of maintaining a second radio link with the relay node until a predetermined time period elapses after reception of the first notification from the relay node.

Methods, systems, and devices for wireless communications are described that provide for mesh connectivity between integrated access and backhaul (IAB) nodes. A first node of an IAB network may determine a routing address for a second node, and communications may be transmitted to the second node based on the routing address to allow for coordination between the first and second nodes. The first node may detect a discovery signal of a second node, and may determine to communicate with the second node based on the discovery signal. The first node may obtain the routing address based on one or more of transmitting a request for the routing address to a third node, establishing a sidelink connection with the second node to obtain the routing address, receiving a mapping between routing addresses and cell IDs that are transmitted in discovery signals, or any combinations thereof.
