Chapter 7

Overall Transmission Structure

Abstract

The overall transmission structure in the time domain (frame, subframe, slots, OFDM symbols) and in the frequency domain (subcarrier, DC handling, bandwidth parts) is described in this chapter. Antenna ports, quasi-colocation, and duplex schemes are also discussed.

Keywords

Slot; subframe; frame; resource block; bandwidth part (BWP); quasi-colocation (QCL); antenna ports; frequency raster; carrier aggregation; supplementary uplink; FDD; TDD; slot format indication (SFI)

Prior to discussing the detailed NR downlink and uplink transmission schemes, a description of the basic time–frequency transmission resource of NR will be provided in this chapter, including bandwidth parts, supplementary uplink, carrier ...
