A Study Of A Variety Of Business Customer S Cross-layer Resource Allocation Under LTE System

In the current period, the design and optimization of the overall radio resource allocation and packet scheduling between the physical layer and MAC layer’s are attracted more and more attention. Cross-layer scheduling technology can take full advantage of the MAC layer and physical layer resources and manage rationally, suppress the interference and increase user’s throughput, thus becoming the new hot spot in communications area. As we know new technologies always raised new issues, for example, different users with different types of services has different scheduling priority and the issue of the upper and lower boundaries of transmission rate to ensure the QoS.Firstly, this paper introduce a new cross-layer scheduling algorithm:CAA-E (Channel Application Aware with Exponential function), after analysis cross-layer scheduling algorithm’s performances in different scenarios, aiming at the existing problems in different traffic type’s schedule calculate function, we presents a new scheduling scheme to optimize scheduling algorithm between the real time user’s and non-real-time user’s and make it more efficiency. After showing improvement through the simulation, we can find that the new algorithm has a larger user throughput improvement, basically optimize the scheduling priority between the two functions.Secondly, to make the scheduling rate meets the various QoS needs of users and to overcome the decline issue of customer’s satisfaction once the scheduled transmission rate is decreased, we propose a user service-based scheduling algorithm to meet the requirements, enable the system to meet the different types of user’s needs when channel state changes in different scenarios.
