Slot structure of long physical uplink control channel (PUCCH) design for 5th generation (5G) new radio (NR)

A base station (gNB), comprising:

• a processor;
• and
• memory in electronic communication with the processor, wherein instructions stored in the memory are executable to:
• receive uplink control information (UCI) using a physical uplink control channel (PUCCH) format that supports more than 2 bits of UCI payload, wherein
• a position(s) in time domain of a demodulation reference signal (DMRS) for the PUCCH format is determined based on a length of a PUCCH for the PUCCH format, a starting OFDM symbol of the PUCCH for the PUCCH format, and a frequency hopping configuration for the PUCCH format,
• the PUCCH with only 1 DMRS does not support a frequency hopping and the PUCCH with 2 or more DMRSs supports a configurable frequency hopping,
• in a case where the length of the PUCCH is 4 to 14 symbols, the PUCCH with 4 DMRSs supports the frequency hopping between the position of the second DMRS and the position of the third DMRS.

A method by a user equipment (UE), the method comprising:

• transmitting uplink control information (UCI) using a physical uplink control channel (PUCCH) format that supports more than 2 bits of UCI payload, wherein
• a position(s) in time domain of a demodulation reference signal (DMRS) for the PUCCH format is determined based on a length of a PUCCH for the PUCCH format, a starting OFDM symbol of the PUCCH for the PUCCH format, and a frequency hopping configuration for the PUCCH format,
• the PUCCH with only 1 DMRS does not support a frequency hopping and the PUCCH with 2 or more DMRSs supports a configurable frequency hopping,
