Enhanced Control Signal and Data Detection for 5G Multicarrier Low-Power Communications

  • Chen Y.
  • Doll M.

As being a complementary technique for Machine Type Communications (MTC) in future 5th Generation (5G) wireless communications, the control mechanism and control signaling should preferably be able to operate at possibly low Signal-to-Noise Ratio (SNR) without interfering the existing cellular network. In this paper, we propose an enhanced mechanism for the control signaling, targeting to low-power communications. It enables the detection of sporadically transmitted data packet of a user at relatively low SNR. Further, we focus on the low-power channel estimation and data detection as an additional proof-of-concept within a multicarrier system. The superimposed pilots are exploited 2-dimensionally in time and frequency to jointly detect the data and estimate the channel.
