Provided in the embodiments of the present application are a physical uplink control channel (PUCCH) transmission method, user equipment and a device, used to solve the technical problem in an existing technology wherein no related method or device supports PUCCH transmission in a new wireless communication system. The PUCCH transmission method comprises: determining the number A of symbols occupied by a PUCCH, the number A being a positive integer; determining a PUCCH structure set that is configured in correspondence to the number A of the symbols, a PUCCH structure comprised in the PUCCH structure set comprising A symbol bits, the PUCCH structure set comprising one or more PUCCH structures, and the number of symbol bits used for transmitting pilot frequency information RS in different PUCCH structures being different when multiple PUCCH structures are comprised, wherein a PUCCH structure is a distribution rule for symbol bits used for transmitting uplink control information (UCI) and symbol bits used for transmitting RS; and determining a PUCCH structure corresponding to the PUCCH from the PUCCH structure set, and performing PUCCH transmission on the basis of the corresponding PUCCH structure.
