摘要：

Personal communications systems are increasingly required to accommodate not only voice traffic, but also various types of data traffic. Generally speaking, voice traffic is symmetric between uplink and downlink, while data traffic can be highly asymmetric. It is therefore inefficient to accommodate data in a conventional TDMA/TDD system with a fixed TDD boundary. In this paper, focusing on the continuous data traffic which requires multi-slots in a circuit based TDMA/TDD system, we propose an algorithm in which the TDD boundaries are moved adaptively to accommodate data traffic efficiently. Comparing with the conventional fixed boundary algorithm, computer simulations confirm that the proposed algorithm has superior performance in the excessive transmission delay of data while maintaining the performance of voice. Moreover, almost the similar performance improvement of the proposed algorithm is confirmed for two different average message sizes of data calls.
