Abstract

Downlink throughput results are presented for cases where the available cell transmission resources are shared between high speed downlink packet access (HSDPA) and dedicated channel users. It is shown that the total cell throughput can be increased by 69% by allocating only 5 high speed downlink shared channel codes and 7 W for HSDPA transmission, compared to a scenario without HSDPA enabled. These results are obtained for a macro cellular scenario with best effort packet traffic. It is demonstrated that part of this throughput increase originates from a better utilization of available cell transmit power when HSDPA is introduced, since reservation of less power control headroom is required.
