- Abstract
- In this paper, we consider fast cell site selection (FCS)
in the downlink of a packet based orthogonal frequency division
multiplexing cellular system. Mobile stations near the cell
boundary can have opportunities to encounter a link that can
provide better condition than the link in service due to the nature
of fading effect. Conventional FCS schemes can track the
variation of channel fading, exploiting a site selection diversity
gain. However, mobile stations near the cell boundary may suffer
from other cell interference (OCI) which is highly time-varying
and unpredictable. To mitigate the OCI effect, we propose a new
FCS scheme that exploits cell selection diversity while preventing
adjacent cells from using the same sub-channels. We also consider
the selection of candidate cells. The performance of the proposed
FSC scheme is analyzed in terms of the capacity using an upper
bound. Finally, analytic results are verified by computer
simulation.
