LTE Downlink Scheduling Algorithm Based on Throughput Optimization
Abstract
In the downlink resource allocation process, the traditional allocation algorithm only considers the channel index value of the user on a single resource block, but does not deeply consider that the allocated resource blocks interact with each other in the actual data transmission process, which may result in the low utilization of the resource block. Therefore, this paper proposes a new judgment mechanism based on the amount of change of resource block transmission data, which using the value of the actual transmitted data volume caused by the allocation of resource blocks to replace the single user channel status value to ensure that the resource block can play a positive role in the transmission of data. The simulation results show that using the new allocation mechanism can effectively improve the throughput of existing algorithms, and at the same time, it can improve the packet loss rate to some extent.
