Abstract: New radio (NR) Uplink (UL) transmissions in an NR physical UL channel can be configured for a user equipment (UE) to communicate with a base station (e.g., gNB). The structures and mechanisms for configured these communications different from long term evolution (LTE) in NR specifications. A UE can generate a UL transmission with symbols on the NR physical channel including demodulation-reference signal (DM-RS) symbols and uplink control information (UCI) symbols. The UL transmissions comprise a DM-RS symbol located at each first symbol with variable lengths. The UE generates the UL transmission as an NR physical UL channel with about a 50% DM-RS overhead with a same or more DM-RS symbols than UCI symbols in a sequential pattern (e.g., an alternating pattern). The UE further maps HARQ-ACK feedback on a PUSCH based a frequency first operation that initiates following the DM-RS symbol located at the first symbol.
