Title: DATA TRANSMISSION METHOD, DEVICE, AND SYSTEM
Abstract:
Provided in the present application is a data transmission method, comprising: a first terminal device receiving a control message sent by an access network device, the control message being used to indicate that the first terminal device performs uplink transmission on a first resource; the first terminal device acting on a second resource, so as to detect a first indicator in a first period, said first period being smaller than a first scheduling time unit, said first scheduling time unit being a scheduling time unit of the first terminal device, and said second resource being part or all of the first resource; when a first indicator that it is permitted for the first terminal device to perform uplink transmission is detected, the first terminal device beginning uplink transmission on the second resource. The described method makes uplink resource use more flexible, and given that signaling overhead of the specified indicator is significantly lower relative to that of a scheduling signal, the present method does not excessively increase mobile communications system overhead.
