Abstract: Provided are methods for transmitting and receiving uplink data, a user equipment and a base station. The method for transmitting uplink data by a user equipment includes: transmitting to a base station a scheduling request (SR); receiving, from the base station, an uplink grant indicating scheduling information for transmitting uplink data, wherein the scheduling information is allocated by the base station according to a volume of the uplink data, the volume being determined by the SR; and transmitting to the base station the uplink data by employing the scheduling information. In this way, the present invention reduces power consumption and time delay during an uplink data transmission process.
