The present invention provides a method and apparatus for transmitting uplink data in an LAA system. The method comprises: receiving mode configuration indication information sent by a network device, the mode configuration indication information being used for instructing to configure a synchronous HARQ mode and an asynchronous HARQ mode for uplink transmission of a user equipment on an unlicensed carrier; and performing, according to the mode configuration indication information, uplink transmission on the unlicensed carrier by using the synchronous HARQ mode or the asynchronous HARQ mode. By means of the method for transmitting uplink data in an LAA system disclosed in the present invention, a failure of a UE to perform data retransmission due to a fact that time resources contended by the UE on an unlicensed carrier are limited in the prior art can be avoided. |
