Chapter 17. Uplink Transmission Scheme
In Chapter 16, a detailed overview of the LTE downlink transmission scheme was provided. In this chapter, a similar overview will be provided for the LTE uplink transmission scheme.
17.1. The Uplink Physical Resource
As already mentioned in the overview provided in Chapter 14, LTE uplink transmission is based on so-called DFTS-OFDM transmission. As described in Chapter 5, DFTS-OFDM is a low-PAR ‘single-carrier’ transmission scheme that allows for flexible bandwidth assignment and orthogonal multiple access not only in the time domain but also in the frequency domain. Thus, the LTE uplink transmission scheme is also sometimes referred to as Single-Carrier FDMA (SC-FDMA).
