Abstract

The invention discloses a resource allocation method, a related device and a system, wherein the method can comprise the steps that a first node sends a first signaling to a terminal, and the first signaling indicates a first resource and a second resource configured to the terminal; wherein the first node is a relay node between the second node and the terminal; wherein the first resource is usedfor data transmission on the access link and is not used for data transmission on the return link; and when a resource conflict may occur between the access link and the backhaul link, activating part or all of the second resources, whrein the activated part or all of the second resources is not used for data transmission of the access link. By implementing the method and the device, resource conflicts between the access link and the return link can be avoided.

Description

Technical field [0001] This application relates to the field of communication technology, in particular to resource allocation methods, related devices and systems. Background technique [0002] In a mobile communication system, the link between stations (such as base stations and remote radio units) is called a backhaul link, and the 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 an optical fiber), and the access link is a wireless link. [0004] In the 5th generation (5G) new radio (NR) system of the 5th generation mobile communication (the 5th generation, 5G) new radio (NR) system, the network deployment needs to be dense, flexible, and high-frequency signal coverage. In order to meet these requirements, the 5G NR system Use relay technology and wireless backhaul links for network deployment. Simply put, one or more relay nodes (RN) are added between the base station and the termin...
