面向工业物联网场景下行短包传输的叠加导频功率优化
Power optimization of superimposed pilot for downlink short-packet transmission in IIoT
摘要
Abstract
The industrial internet of things(IIoT)has great potential in achieving automation and intelligent production.However,existing networks struggle to meet the low-latency and high-reliability communication requirements in indus-trial control scenarios.Motivated by this fact,the power allocation problem of superimposed pilot(SP)for downlink short-packet transmission in IIoT was studied and a lower bound for achievable transmission rates with imperfect channel state information and maximum ratio transmission was derived.Furthermore,the downlink weighted sumrate maximiza-tion problem was formulated and transformed into a geometric programming problem aiming to optimize pilot and data power allocation via successive convex approximation method.Simulation results demonstrate the superiority of the pro-posed power optimization scheme of SP in short-packet transmission.关键词
