As B3G, system is expected to provide high data rate and high spectrum efficiency with low transmission power, the generalized distributed antenna array is a very promising technique, besides OFDM and MIMO. However, to mitigate the cochannel interference and decrease frequency reuse factor, efficient radio resource management is necessary. In this paper, efficient radio resource management algorithms based on interference are proposed for real time speech in FuTURE TDD system in uplink. Compared to the other subcarrier allocation algorithm such as sequential allocation and 2-D intention subcarrier allocation, the algorithms proposed can improve the system capacity to more than double and the spectrum efficiency of 8 kbps speech service is improved to be about 1.3 Mbps/MHz/cell.
