PUSCH DM-RS configuration parameters
The nrPUSCHDMRSConfig
object sets demodulation reference signal
(DM-RS) configuration parameters for a physical uplink shared channel (PUSCH), as defined in
TS 38.211 Section 6.4.1.1 [1].
The object defines the properties of PUSCH DM-RS symbols and indices generation and the
resource elements pattern not used for data in DM-RS symbol locations. The read-only
properties of this object provide the DM-RS subcarrier locations within a resource block (RB),
code division multiplexing (CDM) groups, and time and frequency weights for DM-RS symbols. By
default, the object specifies a single symbol DM-RS at symbol index 2 (0-based) with
configuration type 1 and antenna port 0. Use this object when setting the DMRS
property
of the nrPUSCHConfig
object.
creates a DM-RS
configuration object for a PUSCH with default properties.dmrs
= nrPUSCHDMRSConfig
specifies properties using one or more name-value pair arguments. Enclose each property in
quotes. For example, dmrs
= nrPUSCHDMRSConfig(Name,Value
)'DMRSConfigurationType',1,'DMRSLength',2
specifies
a double-symbol DM-RS with configuration type as 1. Unspecified properties take their
default values.
