SIGNAL TRANSMISSION METHOD APPLIED TO RELAY TECHNOLOGY AND RELATED DEVICE

摘要

Embodiments of this application disclose a signal transmission method applied to a relay technology and a related device, to implement low-overhead cross-link interference management. The method in the embodiments of this application includes: receiving, by a second node, a first signal sent by a first node, where the first signal includes information about a time resource that needs to be occupied by the first node to perform backhaul transmission, and a receiving/sending status of the first node during the backhaul transmission; and when the receiving/sending status of the first node during the backhaul transmission is different from a receiving/sending status of the second node during backhaul transmission, receiving/sending, by the second node, a signal on a resource other than the time resource that needs to be occupied by the first node to perform the backhaul transmission.
