Abstract :
In this paper, the impact of signalling errors on the performance of high speed uplink packet access (HSUPA) in soft handover (SHO) is investigated. The signalling discussed here is the one related to HARQ operation: acknowledgements (ACK) and negative acknowledgements (NACK) in the downlink. Through simulations, it is shown how ACK/NACK signalling errors affect the throughput in both soft handover and non-soft handover cases.
