    Abstract: A method is provided for communication in a wireless telecommunication system. The method comprises transmitting, by a UE, a DMRS, wherein REs carrying the DMRS are separated into a plurality of portions, each of the portions occupying a different OFDM symbol in a single slot of a radio subframe. In one aspect, a new PUSCH DMRS format may provide accurate channel estimates, increased RS density in the time domain at the expense of relaxed PAPR, and/or a symmetric pattern to ease the channel estimation algorithm. The PUSCH DMRS format may provide sufficient RS density in the time domain to enable accurate channel estimation for high Doppler scenarios.
