Abstract:

The paper is devoted to the studies on modifications of mapping of the OVSF channelization codes onto the data and control channels in HSUPA, aiming at increasing the uplink data rates. Appropriate selection of mapping can result in a link throughput gain of up to 28% as compared with the standard HSUPA transmission. An intensive HSUPA link level simulation campaign has been performed to investigate many possible mappings, to optimize the ratios of traffic to pilot channel powers and to measure parameters of the transmitted signal such as the peak-to-average power ratio and the cubic metric. The most important and representative results are summarized in this paper.
