Algorithms and Performance Results for Dynamic HSDPA Resource Allocation

Cell specific algorithms for dynamic sharing of transmit power and channelization codes between HSDPA and Release'99 dedicated channels on the same carrier are proposed. A fast node-B based HSDPA power allocation algorithm is derived, which is able to track the fast power control fluctuations of dedicated channels. Fast channelization code allocation is handled by the centralized RNC. The presented performance results show an improved utilization of the transmission resources. The cell throughput is improved significantly by using these algorithms as compared to using semi-static allocation schemes previously published in the open literature.
