Embodiments of the present invention disclose a multiplexing scheduling method for IAB network and an IAB node. The method includes: determining pre-scheduling information between a first hop and a second hop; receiving activation signaling sent by a second IAB node; and after activating multiplexing scheduling between the first hop and the second hop based on the activation signaling, performing multiplexing scheduling based on the pre-scheduling information, where a first IAB node is used to schedule data transmission on the first hop, and the second IAB node is a parent IAB node of the first IAB node and is used to schedule data transmission on the second hop.

A relay discovery may be performed by apparatuses acting as relay nodes sending first messages indicating existence of a relay capable node and user nodes monitoring the first messages. However, the relay nodes are configured to monitor broadcasted second messages, a second message being broadcasted by a user node that has determined it has a lack of sufficiency of link redundancy. The second message indicates a fast link discovery request for sidelink communications with service of quality requirements.
