Radio unit remote interference management reference signal transmission

An apparatus for wireless communications, comprising:

• at least one memory comprising computer-executable instructions;
• and
• one or more processors configured to execute the computer-executable instructions and cause the apparatus to:
• obtain frequency domain samples of a first copy of a first reference signal (RS) sequence and frequency domain samples of a second copy of the first RS sequence;
• apply a frequency domain function to the first copy of a first reference signal (RS) sequence to obtain a modified first copy of the first RS sequence;
• perform an inverse Fourier transform (IFT) on the modified first copy of the first RS sequence to obtain a circularly time-shifted RS signal in the time domain that forms a first part of an interference management RS;
• perform the IFT on the second copy of the first RS sequence to obtain a second part of the interference management RS;
• and
• output the first and second parts of the interference management RS for transmission.
