Physical layer aspect for evolved Universal Terrestrial Radio Access (UTRA)
This document is related to the technical report for physical layer aspect of the study item “Evolved UTRA and UTRAN” [1]. The purpose of this TR is to help TSG RAN WG1 to define and describe the potential physical layer evolution under consideration and compare the benefits of each evolution techniques, along with the complexity evaluation of each technique.
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.
This document is intended to gather all information in order to compare the solutions and gains vs. complexity, and draw a conclusion on way forward.
This document is a ‘living’ document, i.e. it is permanently updated and presented to TSG-RAN meetings.
Six basic L1 concept proposals are evaluated in this TR:
1. FDD UL based on SC-FDMA, FDD DL based on OFDMA
2. FDD UL based on OFDMA, FDD DL based on OFDMA
3. FDD UL/DL based on MC-WCDMA
4. TDD UL/DL based on MC-TD-SCDMA
5. TDD UL/DL based on OFDMA
6. TDD UL based on SC-FDMA, TDD DL based on OFDMA”
