Abstract
In order to recover transmitted bits most receivers have to estimate the channel impulse or frequency response and equalize the channel influence. In multi-path fading channels with Doppler effect the samples of channel impulse response (CIR) oscillates with Doppler frequencies. It is shown in the paper that CIR estimates calculated by means of a 5G NR waveform inside the 5G NR receiver can be used for remote sensing purposes, e.g. finding distances and velocities of object/vehicles moving in the receiver neighborhood. It is demonstrated that appropriately configured standard Channel State Information (CSI) Reference Signal (RS), used in 5G, allows such environment sensing. In order to increase radar functionality some OFDM symbols in 5G frames can be entirely or partly used as additional pilots, i.e. as object illuminators offered in future 5G services. This gives possibility of creating a completely new 5G NR utilization, which can be called a radar-on-demand (RoD). In the paper results from simulational testing of this idea are presented for different pilot configurations and different frequency estimation methods.
