A method and a device for uplink data operations are provided to enable a user equipment to perform uplink data transmission for a numerology scenario. In embodiments of the present application, the user equipment determines uplink scheduling signaling according to a first correspondence between a numerology and the uplink scheduling signaling, determines a bearer according to a second correspondence between the numerology and the bearer, and performs an uplink data operation according to the uplink scheduling signaling and the bearer. In the present invention, since the user equipment can perform uplink data operations according to the first correspondence between the numerology and the uplink scheduling signaling and the second correspondence between the numerology and the bearer, the user equipment is able to perform uplink data operations for the numerology scenario, thus improving system performance.
