摘要：
We present the potential performance improvements attainable by new enhancements to the WCDMA uplink Improvements can be expected in both system capacity and end-user perceived performance. In this paper we focus on the capacity gains of short TTI, hybrid ARQ and scheduling in Node-B. The performance is studied from both the link-level and system-level perspectives. The link performance results focus on the gains obtained by the introduction of short TTI and hybrid ARQ with soft combining in Node-B. In the system performance results, we also evaluate Node-B based rate scheduling for both 2 ms TTI and 10 ms TTI. Our studies indicate that with the introduction of enhanced uplink the gain in uplink capacity can be in the order of 70-100%.
