NPUSCH DMRS (NB-IoT)

NPUSCH DMRS is the uplink user's shared channel Demodulation Reference Signal (DMRS) and is transmitted in each resource block allocated to the user.

The DMRS is multiplexed with the NPUSCH symbols. The number and allocation of DMRS symbols depends on the Subcarrier Spacing and NPUSCH Format as defined in the LTE standard.
