Abstract
This paper briefs the problem of optimal multiuser scheduling in HSDPA. The modulation and coding schemes (MCSs), numbers of multicodes and power levels for all users are jointly optimized at each scheduling period, given that only limited Channel Quality Indicator (CQI) information, as specified in the HSDPA standard [1], is fed back to the BS. An integer programming model is proposed in order to provide a globally optimal solution to the multiuser scheduling problem. Due to the complexity of the globally optimal method, a swarm intelligence approach, namely particle swarm optimization (PSO), is subsequently proposed. The experimentations suggest that it potentially provides a near-optimum performance with significantly reduced complexity. © 2008 Springer-Verlag Berlin Heidelberg.
