SpletPTRS mapping starts at the first symbol that contains PDSCH in the slot. Then it is mapped to every L symbol, based on time density 1/L. PTRS is not transmitted in OFDM symbols that contain a CORESET or a PDSCH DMRS. PTRS mapping restarts at each DMRS symbol, and is then mapped relative to this symbol. SpletThe PDSCH data is updated based on the HARQ state. Creating Transmit Waveform - Pass the data generated by the HARQ process to the lteRMCDLTool function to produce an OFDM modulated waveform, containing the physical channels and signals. Noisy Channel Modeling - Pass the waveform through a fading channel and add noise (AWGN).
