Abstract
The present application provides a PUCCH-based uplink control information transmission method and apparatus. User equipment determines, according to downlink control information (DCI), a format of a physical uplink control channel (PUCCH) and/or information of a used orthogonal sequence; and the user equipment transmits, according to the format of the PUCCH and/or the information of the used orthogonal sequence, uplink control information borne by the PUCCH. The present application can implement selection of a transmission structure of a PUCCH to transmit uplink control information.
