HSDPAMulti-UEOption

The HSDPA Multi-UE Option provides developers and operators of evolved 3G systems with acomprehens ive test environment for performance evaluation, stress testing and benchmarking of aNode B and its i scheduling algorithms.
•Node B schedulertesting, verification andoptimization•Real-time simulation of 32HSDPAmobiles•Independent mobilitymodels represent-ing real-time fading channel scenarios•Full Layer1support of all UEcapabilityclasses•Supports data rates up to 13.97Mbps•Real-time simultaneous decode of HS-SCCH and HS-DSCH forall UEs•Full MAC-hs and HARQ and re-orderingcapabilityforall UEs•Deterministic and repeatable channelbehavior•Advanced measurement logging andcharting capabilities forall UEs•Scalable system architecture to provideadvanced test configurations The introduction of High Speed Downlink Packet Access (HSDPA)into Release 5 of the 3GPP specifications provides enhanced supportfor packet data services with reduced latencies and a peak data rateup to 13.97 Mbps. These features enable improved data service quality and enhanced cell capacity.The key functionality to achieve these improvements is in the NodeB and includes downlink packet scheduling, fast re-transmission andlink adaptation techniques.Efficient operation of this complex functionality depends on the real-time downlink channel conditions, QoS and terminal capability class of each HSDPA mobile in the cell. This makes integration, test andverification difficult, especially in the early stages when real HSDPAmobiles are unavailable. Forthe verylatestspecifications visit
