| Abstract(in English) | In this paper, we propose improved method for our previously reported online probabilistic transmission power control method of base stations (BSs) in heterogeneous networks where low transmission-power pico-BSs are overlaid onto a high transmission-power macro-BS. Previously reported method requires only a single metric to be exchanged among BSs, which is a system throughput measure at each cell. The previous method adaptively controls the activation probability of each BS individually, depending on the time variation in the system throughput and the temporal transmission power states of each BS. As a result, the system throughput can be enhanced due to appropriately reduced inter-cell interference. However, since the previous method updates the transmission power of each BS with small step size at each iteration, there is a room for further improvement in the convergence rate and tracking capability to the change in user distribution. The proposed new algorithm defines limited set of candidate transmission power levels and application probability of each candidate transmission power level is updated based on the time variation in the system throughput and the temporal transmission power states of each BS. As a result, the performance after convergence and the tracking ability to the change in user distribution is improved compared to the previous one. Computer simulation results show the effectiveness of the proposed methods compared to the conventional approaches. |
