Performance comparison of DTX detection schemes for 5G NR PUCCH

The detection of discontinuous transmission (DTX) at the receiver is required, along with the demodulation of the uplink control information (UCI) that is transmitted on the 5G New Radio (NR) Physical Uplink Control Channel (PUCCH). Two feasible detection schemes of the DTX for 5G NR PUCCH format 0 are considered and the performance comparisons of these are carried out by the computer simulations under several situations. The simulation results show that these meet the performance requirements described in the 3GPP standards.
