A user equipment (UE) is described. The UE includes a processor and memory in electronic communication with the processor. Instructions stored in the memory are executable to determine the uplink control channel (PUCCH) format and configuration based on a signaling from a gNB. The instructions are also executable to determine the control channel used for uplink control information (UCI) feedback. The instructions are further executable to determine the resource of the control channel for UCI feedback. The instructions are additionally executable to transmit UCI on the selected channel. A long PUCCH may employ a format that includes a waveform, a number of resource blocks (RBs), a reference symbol (RS) pattern, and/or orthogonal sequences on RS and data symbols, and/or one or more control resource regions.
