An up-link/down-link asymmetric slot allocation algorithm in CDMA/TDD-based wireless multimedia communications systems

摘要

In this paper, we propose an up-link/down-link asymmetric slot allocation algorithm for CDMA/TDD-Based wireless multimedia communications systems. We evaluate the average delay performance of the proposed algorithm by computer simulation, assuming a practical multicell environment and a multimedia service model which consists of several kinds of up-link/down-link symmetric and asymmetric services. Our simulation results show that the proposed algorithm, which can flexibly cope with up-link/down-link traffic asymmetry, improves the average delay performance as compared with symmetric slot allocation and fixed asymmetric slot allocation algorithms.
