5G NR Physical Downlink Shared Channel (PDSCH)

Learn about downlink data transmission in 5G New Radio (NR). Explore the Physical Downlink Shared Channel (PDSCH) processing chain which includes LDPC coding, layer mapping, how resource elements are allocated for PDSCH transmission, and the different types of PDSCH mapping. A special PDSCH mapping type is used for mini-slots or partially allocated slots, a feature that allows for reduced latency in 5G NR transmission. We walk you through MIMO precoding, which, although not specified on the downlink, is a critical component of the downlink chain. The example demonstration walks you through PDSCH resource allocation options and mapping in 5G Toolbox and concludes with a quick word on transport block sizes.
