PUSCH precoder matrix indication reporting information
You can use
determine the correct size of the vector PMI required for closed-loop
spatial multiplexing operation. PMI is a column vector with
Currently, only wideband PMI reporting is defined by the standard.
Thus, the number of subbands,

Number of uplink resource blocks, specified as a positive scalar integer.
NTxAnts— Number of transmission antennas1 (default) | Optional | 2 | 4
Number of transmission antennas, specified as a positive scalar integer. Optional. Valid values are 1, 2, and 4.
Information related to PMI reporting, returned as a structure with these fields.

Subband size, in resource blocks (RBs), returned as a scalar
integer. This parameter is equal to
NSubbands— Number of subbands for PMI reportingscalar integer
Number of subbands for PMI reporting, returned as a scalar integer. This parameter is equal to 1 for wideband PMI.
Maximum permitted PMI value for the given configuration, returned
as a scalar integer. Valid PMI values range from 0 to
