1 Scope Word‑p. 6
The present document captures the agreements of the different techniques for 1.28 Mcps TDD Enhanced Uplink, namely the support of Node-B controlled rate scheduling, Node-B controlled physical resource scheduling, hybrid ARQ, and higher order modulation, with regards to the overall support of UTRA TDD Enhanced Uplink for the 1.28Mcps mode.
The technical objective of this work item is the introduction of Enhanced Uplink functionality in UTRA 1.28Mcps TDD, to improve uplink performance for background, interactive and streaming-based traffic.
