Intelligent Energy Solution for Railway Communication Base Stations
This paper proposes an intelligent reflecting surface (IRS)-assisted energy efficiency optimization algorithm to address the problem of energy efficiency (EE) degradation in high-speed rail communication systems caused by line-of-sight link blockages between base stations and trains. The effective operation of railway stations and improved passenger flow have a significant impact on the availability of mobility services, passenger throughput and passenger experience. In order to unlock the challenge and increase rail capability, the railway industry and governments worldwide are preparing 5G communication infrastructure for the next generation and beyond, aiming to provide ultra-high performance connection with millisecond latency, gigabit per second. This technical report explores how network energy saving technologies that have emerged since the 4G era, such as carrier shutdown, channel shutdown, symbol shutdown etc.
