Abstract
Embodiments of the present disclosure disclose an uplink data transmission method and apparatus and a storage medium. The method comprises: a terminal sending uplink data using an unlicensed resource; if the sending of the uplink data using the unlicensed resource fails, sending the uplink data using a licensed resource; the terminal sending a preamble sequence using an unlicensed resource; sending uplink data in a transmission time interval corresponding to a sending moment of the preamble sequence; and if a random access response carrying uplink authorization information is received within a preset period of time, resending the uplink data using a licensed resource indicated by the uplink authorization information. A base station detects the preamble sequence sent by the terminal using the unlicensed spectrum and the uplink data sent by the terminal, and when the preamble sequence is correctly decoded but the uplink data is not correctly decoded, the random access response carrying the uplink authorization information is sent to the terminal within the preset period of time using the licensed resource.
