Guard interval-based waveform with data part and tail part

A wireless device, comprising:

• a memory;
• at least one transceiver;
• and
• at least one processor communicatively coupled to the memory and the at least one transceiver, the at least one processor configured to:
• obtain data for transmission in a guard interval (GI)-based waveform with a data part and a tail part;
• obtain a unique word (UW) sequence for the tail part;
• and
• obtain a suppression signal with filter coefficients configured to suppress leakage from the data part to the tail part;
• map the data, the UW sequence, and the suppression signal to a set of reserved time-domain resources based on a time-domain resource mapping and reservation rule to produce Discrete Fourier Transform (DFT) input data;
• perform DFT processing on the DFT input data to produce Inverse Fast Fourier Transform (IFFT) input data;
• perform IFFT processing on the IFFT input data to produce the GI-based waveform with the data part and the tail part;
• and
• transmit, via the at least one transceiver, the GI-based waveform.
