The present application relates to the field of wireless communications technologies, and in particular, to a method and a device for transmitting data, to solve a problem in the prior art that: a length of downlink transmission interference time may be increased due to a frame loss in a handover process, and consequently it takes a relatively long time for transmitting data at an air interface, and delay of train control data is increased. The method according to embodiments of the present application includes: caching a downlink valid data frame for a user equipment during a handover process of the user equipment; and sending the cached downlink valid data frame after a handover of the user equipment ends. According to the embodiments of the present application, user data is not transmitted at an air interface during a handover process, which prevents the user data from being lost at the air interface during the handover process, eliminates a length of downlink transmission interference time caused by a frame loss during the handover process, and shortens a length of downlink transmission interference time, thereby shortening duration of retransmitting data at the air interface data and delay of train control data. |
