摘要
An important issue in wireless multimedia communications is to cope with the traffic asymmetry between uplink and downlink. The asymmetrical slot allocation in the code-division multiple-access systems with time-division duplex mode (CDMA/TDD systems) can be a good solution for this problem, However, the level of traffic asymmetry can be significantly different from cell to cell. In this letter, we calculate the utilization of CDMA/TDD system for multicell model, In addition, we suggest an optimal slot allocation that maximizes the frequency utilization.
