Abstract
|
With the rapid development of communication technology , mobile communication subscriber is a sharp increase in the available radio resources are very limited . How to guarantee quality of service at the same time as much as possible to improve the utilization of system resources , has become a radio resource management need to address the important issues . Time Division - Synchronous Code Division Multiple Access ( TD - SCDMA ) system as the background, packet scheduling ( PS ) algorithm for wireless resource management conducted in-depth research . First, a brief description of the structure and function of the entire system , the analysis of the role of PS algorithm and radio resource management algorithms and their respective division . Next, introduce three typical packet scheduling algorithm based on elaborated the principle and application of TD-SCDMA system PS scheduling algorithm . Focus on three key parameters affect the PS algorithm efficiency - radio link control layer buffer occupancy ( RLC BO ) , the packet scheduling threshold and CELL_PCH state support the number of users for simulation and analysis , overall performance is given appropriate recommendations values ??.
