SpletCreate a PDSCH configuration object. Specify the modulation scheme (16-QAM) and the number of layers (2). Allocate all resource blocks (RBs) to the PDSCH (full band allocation). You can also specify other time-allocation parameters and demodulation reference signal (DM-RS) settings in this object. Splet27. jan. 2024 · PDSCH DM-RS can support multiple layer MIMO transmission by scheduling multiple orthogonal DMRS ports, one for each layer. Orthogonality is achieved by CDM … SpletFactors which Decide Higher Data Rate on PDSCH Channel Modulation. Higher data rate depends upon modulation scheme. Modulation scheme and quantity of redundancy depend upon the RF channel conditions. UEs experiencing good channel conditions are more likely to be allocated higher order modulation. schemes with less redundancy. MIMO gastineau carolina log home pics

SpletPRACH does not use a modulation scheme. PBCH and PDCCH both use QPSK to help ensure reliable reception across the whole coverage area. PBCH also uses a low coding rate to further help reliable reception. Physical signals do not use modulation schemes.
