Abstract	This paper proposes a combined resource management and scheduling scheme for multi-channel wireless systems based on the knowledge of the channel quality information. In multi-channel wireless systems, such as MIMO, SDMA, or OFDMA systems, the quality of individual channel changes with time in a fairly independent manner, and is very much user-dependent. Consequently, the overall system performance or capacity heavily depends not only on the time (i.e., the scheduling scheme) but also the way (i. e. the radio resource management scheme) that channels are allocated to users. Unlike the most existing scheduling and/or RRM schemes for wireless systems, our approach employs multiple schedulers, each of which is responsible for allocating a single channel (or a channel group) to different users. In other words, the proposed scheme carries out the RRM and scheduling at the same time. Further, we introduce the notion of request-based scheduling as a way to extend the advantage of opportunistic scheduling to channel axis. Numerical experiments demonstrate that a significant performance improvement can be achieved by the parallel scheduling scheme, and the improvement may even be magnified via request-based scheduling.
