Abstract
A method for transmitting a PTRS by a transmitting node may include: identifying a time density and a frequency density of PTRS; identifying a first offset based on the frequency density of PTRS and a second offset based on N times the frequency density of PTRS, N being an integer equal to or greater than 2; determining a position of a subcarrier to transmit a first PTRS and a position of a subcarrier to transmit a second PTRS using the first offset and the second offset; determining a resource block (RB) to transmit each of the first PTRS and the second PTRS from resources allocated to a receiving node; configuring a data channel including data, demodulation reference signals (DMRSs) for demodulation of the data, the first PTRS, and the second PTRS; and transmitting the data channel to the receiving node.
