Title

Measurement-based band allocation in multiband CDMA

Author(s)

Andrew, Lachlan L. H.

Abstract

Multiband (or multi-carrier) CDMA is a promising approach to increasing the capacity of CDMA systems, while maintaining compatibility with existing systems. This paper proposes an algorithm for allocating new calls to bands based on measured path gains, or alternatively, on estimates of the mobile stations' positions. By separating strong and weak users into separate bands, this algorithm reduces the other-cell interference on the uplink. It is shown to provide significantly better performance than alternative algorithms when hard handoff is used. An additional benefit of this algorithm is a reduction in the dynamic range required for uplink power control.
