An uplink/downlink asymmetric slot allocation algorithm in CDMA/TDD-based wireless multimedia communications systems
Hiroyuki Yomo, Shinsuke Hara · 2002
We propose an uplink/downlink 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 uplink/downlink symmetric and asymmetric services. Our simulation results show that the proposed algorithm, which can flexibly cope with uplink/downlink traffic asymmetry, improves the average delay performance as compared with symmetric slot allocation and fixed asymmetric slot allocation algorithms.
