Abstract [en]

The uplink random access channel will be a key part of the 3rd generation wireless systems as it will be used for initial contact with base stations as well as for packet data transmission. In this paper, the throughput of preamble power ramping with 16 orthogonal channels currently adopted as the UTRA standard for random access is evaluated. It is shown that the tight power restrictions necessary in a CDMA system leads to degraded throughput at high loads. A modification to the scheme that significantly increases throughput for high loads is suggested.
