Downlink Data in 5G NR

Learn about downlink data transmission in 5G New Radio (NR). This video looks at the downlink shared channel chain, which includes LDPC coding, the physical downlink shared channel chain, 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.

The video also walks through MIMO precoding, which, although not specified on the downlink, is a critical component of the downlink chain.

The video includes an example demonstration that walks through PDSCH resource allocation options and mapping in 5G ToolboxTM.

The video concludes with a quick word on transport block sizes.
