Non-coherent physical uplink control channel (pucch) format for a time-domain single-carrier waveform

An apparatus for wireless communication by a user equipment (UE), comprising:

• a memory comprising executable instructions;
• and
• one or more processors configured to execute the executable instructions and cause the UE to:
• receive, from a base station (BS), a message indicating multiple configurations for physical uplink control channel (PUCCH) transmission;
• select from a sequence database, a sequence to be used for the transmission of a PUCCH in accordance with one of the multiple configurations indicated by the message from the base station;
• and
• transmit the PUCCH using the selected sequence.

A non-transitory computer-readable medium comprising executable instructions that, when executed by one or more processors of a user equipment (UE), cause the UE to:

• receive, from a base station (BS), a message indicating multiple configurations for physical uplink control channel (PUCCH) transmission;
• select, from a sequence database, a sequence to be used for the transmission of a PUCCH in accordance with one of the multiple configurations indicated by the message from the base station;
• and
• transmit the PUCCH using the selected sequence.
