1  ScopeWord‑p. 6

This present document details and compares proposed enhancements to the UTRA TDD uplink in terms of gains and complexity and draws conclusions on future work.
This document is the technical report for the Release 6 study item "Uplink Enhancements for UTRA TDD" [1]. The purpose of this TR is to help TSG RAN WG1 to define and describe the potential enhancements under consideration and compare the benefits of each enhancement with earlier releases for improving the performance of the UTRA TDD uplink, along with the complexity evaluation of each technique. The scope is to either enhance uplink performance in general or to enhance the uplink performance for background, interactive and streaming based traffic.
This activity involves the Radio Access work area of the 3GPP studies and has impacts both on the Mobile Equipment and Access Network of the 3GPP systems.
