Physical Transmission Resources

Abstract

The basic time-frequency structure of LTE transmission is the topic of this chapter. LTE supports both FDD and TDD using the same basic radio-interface structure, thereby adding to the overall spectrum flexibility without fragmenting the LTE technology. This chapter also discusses coexistence between LTE TDD and 3G TDD systems such as TD-SCDMA.
