LTE DL-SCH and PDSCH Processing Chain

In LTE the Downlink Shared Channel (DL-SCH) is a transport channel used for the transmission of user data, dedicated control and user-specific higher layer information and downlink system information. The Physical Downlink Shared Channel (PDSCH) is the physical channel that carries the DL-SCH coded data. This example shows the different stages involved in the Downlink Shared Channel (DL-SCH) and Physical Downlink Shared Channel (PDSCH) processing and provides access to the data from these intermediate stages.
