Abstract

System capacity can be increased if the base station (BS) is equipped with additional channel state information (CSI) of the downlink channel. In an FDD system, this means that mobiles have to provide CSI through some feedback mechanism. Although the two feedback modes included in the present WCDMA HSDPA standard have been designed for one-by-one transmission, a significant downlink throughput improvement can be achieved with multiuser scheduling (MS) [1]. In this paper we propose two practical MS algorithms compatible with the current HSDPA specification, that provide a significant performance gain at moderate power regimes, compared to the systems that transmit sequentially to the user with best channel.
