Abstract

The present application discloses a resource allocation method, a related device, and a system. The method may include: the first node sends a first signaling to the terminal, and the first signaling indicates the first resource and the second resource configured for the terminal; the first The node is a relay node between the second node and the terminal; the first resource is used for data transmission on the access link, not for data transmission on the backhaul link; when the access link and the backhaul link may When a resource conflict occurs, a part or all of the second resources are activated, and the activated part or all of the second resources are not used for data transmission of the access link. By implementing the present application, resource conflicts between the access link and the backhaul link can be avoided.

Description

technical field [0001] The present application relates to the field of communication technologies, and in particular to a resource allocation method, related devices and systems. Background technique [0002] In a mobile communication system, a link between stations (such as a base station and a remote radio unit) is called a backhaul link, and a link between a station and a terminal is called an access link. [0003] In a 4G (LTE) system, the backhaul link is usually a wired link (such as optical fiber), and the access link is a wireless link. [0004] In the fifth generation mobile communication (the 5th generation, 5G) new air interface (new radio, NR) system, there are requirements for network deployment to be dense, flexible, and high-frequency signal coverage. In order to meet these requirements, the 5G NR system Network deployment is performed by using relay technology and adopting wireless backhaul links. Simply put, one or more relay nodes (relay node, RN) are add...
