Since the interference is related to the capacity and performance of DS/CDMA systems, it is necessary to investigate other-cell-interference characteristics according to the location of a user. In this paper, we specifically analyze the ratio of the intercell interference to the total power received from the own cell in downlink, defined as the other-cell-interference factor, as a function of normalized distance. Additionally, the maximum transmission rate under uniform user distribution throughout the cell is simulated when TDX mode packet scheduling is applied. The results show that a maximum transmission rate up to 7.6 Mbit/s for the privileged user could be supported when the bandwidth is 1.2288 MHz, orthogonality factor is 0.9 and the normalized distance is 0.1.
