1 Scope p. 6
The present document captures the agreements of the different techniques for FDD Enhanced Uplink, namely the support of Node B controlled scheduling, hybrid ARQ and shorter TTI, with regards to the overall support of UTRA FDD Enhanced Uplink.
The technical objective of this work item is the Enhanced Uplink functionality in UTRA FDD, to improve the performance of uplink dedicated transport channels.
