| Abstract(in English) | In this paper, we investigate uplink system capacity of the 3GPP's TDD system, and propose techniques to increase the capacity. Simulation results showed that the capacity of the system becomes lower than that of the FDD-CDMA system, and the introduction of DTX gives only a small improvement in capacity. To solve this problem, we propose a slot re-allocation technique in which a slot assignment of each talk spurt is dynamically changed depending on link quality. The technique achieves twice as much capacity as that of the original TDD system. This paper further proposes an extension to the 3GPP's specification from a TDD/CDMA/TDMA based one to a TDD/CDMA based one. With this extension, the capacity is improved by about three times as much as the original TDD/TDMA/CDMA system. |
