PDSCH configuration parameters
The nrPDSCHConfig
object sets physical downlink shared channel
(PDSCH) configuration parameters, as defined in TS 38.211 Sections 7.3.1, 7.4.1.1, and 7.4.1.2
[1].
This object defines all the properties involved in the PDSCH processing chain, including scrambling, symbol modulation, layer mapping, virtual resource blocks (VRB) to physical resource blocks (PRB) interleaving, and resource element (RE) mapping with the reserved resources patterns. The object also contains properties of the associated physical reference signals, such as demodulation reference signal (DM-RS) and phase tracking reference signal (PT-RS).
By default, the object configures a physical downlink shared channel occupying a 10 MHz bandwidth at, 15 kHz subcarrier spacing (52 resource blocks) and spanning over 14 OFDM symbols in a slot.
creates a PDSCH
configuration object with default properties.pdsch
= nrPDSCHConfig
specifies properties using one or more name-value pair arguments. Enclose each property in
quotes. For example, pdsch
= nrPDSCHConfig(Name,Value
)'NSizeBWP',200,'NumLayers',7
specifies 200 PRBs in
the bandwidth part (BWP) and 7 transmission layers. Unspecified properties take their
default values.
