| Abstract | (in Japanese) | (See Japanese page) |
| (in English) | In this paper, we propose improved methods for online probabilistic activation/deactivation control of pico-base stations (BSs) in heterogeneous networks where low transmission-power pico-BSs are overlaid onto a high transmission-power macro-BS. By deactivating the signal transmission of unnecessary pico-BSs, the inter-cell interference is reduced resulting in an increase in system throughput. The proposal in the paper is applicable to our previously reported method. The reported method does not rely on a priori knowledge of probability distributions of user locations or the traffic load of the entire system coverage. The method requires only a single metric to be exchanged among BSs, which is a system throughput measure at each cell. The reported method adaptively controls the activation probability of each pico-BS individually, depending on the time variation in the system throughput and the temporal activation/deactivation states of each pico-BS. Two improved methods for the reported method are presented in the paper, aiming at better convergence rate, stability, and higher system throughput after convergence. For achieving this, first method additionally takes into account the transition of activation/deactivation states during the control of activation probability in order to exclude the effect of time valuation in the system throughput due to the transition of other pico-BS’s activation/deactivation states. The second method applies the moving average of past system throughput for the same purpose. Computer simulation results show the effectiveness of the proposed methods compared to the previous one. | |
