| Abstract: | TD-SCDMA technology is developing rapidly, and applied in a large-scale. As the future evolution technology over TD-SCDMA System, TD-LTE Terrestrial Radio Access Network technology specifications have been approved by 3GPP, and are now being perfected and tested. In this paper, network system architecture, Physical layer technology and other layers specifications are analyzed. And also the improvement on and development of TDD, OFDM, MIMO and Smart Antenna, NAS layers is described, the future development of TD-LTE discussed. |
