This finds applications in the upcoming 3GPP NR systems which have designed short uplink control transmissions for latency constrained applications and for embedding phase tracking reference signals in the uplink transmissions of mmWave systems. A naive approach to multiplex RS and data in a single ...
After being zero-padded and after the 𝑁N-point inverse DFT (IDFT) of 𝑋𝑘Xk is taken, the transmitted signal samples 𝑥𝑛xn can be written as [26]: 𝑥𝑛=1𝑁√∑𝑘=0𝑀−1𝑋𝑘𝑊−𝑘𝑛𝑁=1𝑀𝑁√∑𝑘=0𝑀−1∑𝑚=0𝑀−1𝑣𝑚𝑊𝑘𝑚...
