Application: Distributed antenna system, wireless communication method, and centralized station (Patent ID: US20240072847A1)
The patent filed by Nippon Telegraph and Telephone Corp describes a distributed antenna system that includes multiple base stations performing MIMO transmission to user terminals at the same frequency. An aggregation station receives communication path information from each base station for each user terminal, determines if two base stations and two user terminals are aligned, and generates information for adjusting transmission beams in such cases. The system utilizes NOMA processing to optimize transmission data for user terminals based on power differences or ratios, enhancing cooperation between base stations and user terminals for increased gains.
The wireless communication method outlined in the patent involves receiving communication path information from multiple base stations performing MIMO transmission, determining alignment of base stations and user terminals, and adjusting transmission beams accordingly. By utilizing NOMA processing, the method optimizes transmission data for user terminals based on power differences or ratios, enhancing gains through cooperation between base stations and user terminals. The aggregation station in the system plays a crucial role in aggregating information from base stations, determining alignment, and controlling transmission beams based on the generated information, ultimately improving the efficiency and performance of the distributed antenna system.
