Publication number: 20260143515Abstract: A Radio Access Network Intelligent Controller (RIC), a dynamic Resource Block (RB) allocation method, and a related base station. The dynamic RB configuration method include the followings. The RIC obtains network status information from multiple BSs. Based on the network status information, the RIC identifies at least one first UE among multiple UEs that is experiencing interference. The RIC sets multiple dynamic RB allocation strategies corresponding to multiple BSs based on the network status information, at least one first UE, and at least one first BS. The RIC transmits the multiple dynamic RB allocation strategies to corresponding to ones of the multiple BSs. In response to a dynamic adjustment condition being triggered, the RIC re-obtain the network status information, to update the multiple dynamic RB allocation strategies, and transmit the multiple updated dynamic RB allocation strategies to corresponding ones of the multiple BSs.Type: ApplicationFiled: November 21, 2024Publication date: May 21, 2026Applicant: Industrial Technology Research InstituteInventors: Tzu-Lin Wang, Chai-Hien Gan, Wan-Yi Lin, Kai-Wen Chen
