The Research Of TD-SCDMA System Packet Schedule Algorithm

The number of people using mobile telecommunication has been sharply increasing with the rapid development of the communication technology. However, the radio recourses are limited. It has become a primary problem necessary to be solved that how to raise the utilization ratio of system resource while ensure the user' quality of service.Base on TD-SCDMA system, Packet Schedule (PS) algorithm for radio resources management is intensive researched by this article. First of all, the construction and functions of the whole TD-SCDMA system are described to the point, the function and work division of the PS algorithm and other radio resources management algorithms are analyzed. Based on the introduction of three typical PS algorithms, the theory of PS algorithm of TD-SCDMA is expatiated in detail. Afterwards, as the top-drawer part of whole article, three important parameters-Radios Link Control layer Buffer Occupancy (RLC BO), PS threshold and number of CELL_PCH support user are emulated and analyzed. By synthetic comparison, the rational values of three parameters are recommended.
