The paper presents system level simulation results on future base station energy saving using a time-triggered sleep model. The energy efficiency of future base station is compared in macro cellular network against a comparable baseline without usage of sleep modes. Furthermore, results for corresponding 4G case are shown using a restricted set of sleep modes supported by 4G networks. The paper also...
In this paper we investigate and enhance the user-pairing probability in a system employing multi-user superposition transmission (MUST). In order to improve the multiuser pairing probability, we propose an additional feedback of the second best channel state information (CSI) consisting of channel quality indicator (CQI) and precoding matrix indicator (PMI). We analyze the pairing-probability and...
The target of the paper is to provide guidelines for indoor planning and optimization using an outdoor-to-indoor repeater or a dedicated indoor system. The paper provides practical information for enhancing the performance of high-speed downlink packet access (HSDPA) in an indoor environment. The capabilities of an outdoor-to-indoor analog WCDMA repeater are set against a dedicated indoor system and,...
