  10. TDD Technology Flexible in spectrum: Requires unpaired frequency bands only It is difficult to find paired frequency bands under 2GHz Same frequency for uplink and downlink: Smart antenna can be used Support asymmetric service Low cost for Node B Lower power PA with smart antenna High spectrum efficiency leveraged by Smart Antenna, JD and TDD Page 10

  11. OFDM is a digital multi-carrier modulation scheme, which uses a large number of closely-spaced orthogonal sub-carriers. Each sub-carrier is modulated with a conventional modulation scheme (such as QPSK, 16QAM, 64QAM) at a low symbol rate similar to conventional single-carrier modulation schemes in the same bandwidth.
