Reference signal and control information processing in 5G-NR wireless systems

A non-transitory computer-readable storage medium that stores instructions for execution by one or more processors of a base station operating in a 5G network, the instructions to configure the one or more processors for New Radio (NR) communications above a 52.6 GHz carrier frequency and to cause the base station to:

• encode radio resource control (RRC) signaling with a cyclic shift value in time domain for transmission to a user equipment (UE), wherein the cyclic shift value is associated with a demodulation reference signal (DM-RS) antenna port (AP) of a plurality of available DM-RS APs;
• decode a single carrier based waveform DM-RS sequence corresponding to the DM-RS AP, the DM-RS sequence received from the UE with uplink data via a physical uplink shared channel (PUSCH) using a carrier above the 52.6 GHz carrier frequency, wherein the DM-RS sequence is a single carrier based waveform DM-RS sequence generated using a base sequence and the cyclic shift value, wherein a hopping pattern is applied to the base sequence, and wherein the hopping pattern is initialized using at least a single carrier with frequency domain equalizer (SC-FDE) block index;
• determine a channel estimate of the PUSCH using the DM-RS sequence;
• and
• decode the uplink data based on the channel estimate;
• and
• encode the single carrier based waveform DM-RS sequence with uplink data for transmission to a base station using a physical uplink shared channel (PUSCH).
