HSUPA Measurements Solutions For Real-Time Spectrum Analysis

HSUPA is high speed uplink packet to improve uplink throughput to 5.76Mbps. To achieve this uplink throughput improvement, a new dedicated uplink channel, E-DCH (Enhancement Dedicated Channel), is specified in 3GPP release 6 (HSUPA). In addition, Hybrid ARQ on Uplink has been adjusted to be shorter than in the previous release 99.

When operating successfully together, HSUPA and HSDPA achieve a significant improvement in the overall system performance.
– System capacity increase
– Reduction in end user packet call delay
– User throughput increase

To add to the complexity, new channels have been added on the downlink for signaling between the user equipment (UE) and the base station.
