3. A method by a user equipment (UE), the method comprising:
transmitting uplink control information (UCI) on a physical uplink control channel (PUCCH) resource using a 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 resource using the PUCCH format is determined based on a length of the PUCCH resource, a starting OFDM symbol of the PUCCH resource, a frequency hopping configuration for the PUCCH resource, and a parameter of the quantity of DMRS,
a 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 frequency hopping is configured, the parameter, configured by higher layer signaling, of the quantity of DMRS is configurable as 1 or 2 DMRSs in a hop for PUCCH length 10 to 14 symbols using the PUCCH format that supports more than 2 bits of UCI payload, and the same number of DMRSs is applied in each hop, thus results in a total of 2 or 4 DMRSs in the PUCCH; and the same DMRS positions are determined as with frequency hopping.
