Chapter 11: Multi-Antenna Transmission
Abstract
Multi-antenna transmission is a key feature of NR, for both lower-frequency bands below 6 GHz and the mm-wave frequency bands. This chapter focuses on multi-antenna precoding, including the uplink reporting of CSI for downlink multi-antenna precoding as well as codebook-based and non-codebook-based uplink precoding.
