LTE Resource Schedule Analyse In Different Scene

LTE system has increasingly become a mainstream wireless broadband network,resource allocation and scheduling algorithm is the core function,to provide services for the realization of LTE;high speed communication network,the system's goal is to get the maximum velocity and minimum delay,but the number of users of the scene,with different emphasis,the target is also different;but the current network.Resource scheduling strategy did not focus,unity,so that the network performance and service provision can not achieve the best.This paper mainly studies the characteristics and difficulties of LTE scheduling in different scenarios,to slove PUCCH,PDCCH signaling overhead problem,proposed an adaptive strategy;to slover power distribution,puts forward the method of setting the scene;to maximize user throughput,puts forward the optimization of resouse decreasing and adjusting RB&MCS and different HARQ target;to slove multi-user scheduling balance,proposed fair scheduling and bucket principle combining scheduling strategy;for large traffic scenarios and the rapid increase in the use of spectrum overhead problems,propose appropriate elongated various types of timers reduce signaling overhead and the appropriate scheduling strategy package.Through these solutions,the original resource scheduling is broken.In the LTE resource allocation optimization,performance improvement,the scene has a significant gain.Through the simulation system,the effect of these strategies are compared with the baseline,cell throughput,system stability or wireless utilization rate have been greatly improved.
