Abstract

Traffic asymmetry between uplink and downlink is one of the most notable characteristics in wireless multimedia communications. CDMA/TDD systems with unbalanced slot allocation can be a good solution for this problem. However, the level of traffic asymmetry may be significantly different from cell to cell. In this paper, we calculate the capacity of CDMA/TDD systems under given patterns of traffic asymmetry. Using the results, we investigate optimal slot allocation that maximizes the frequency utilization in terms of the whole cellular system
