摘要：
A method and apparatus for data transmission are provided. The method is applied to a user equipment that detects a current timing advance (TA) in a target time unit to obtain a detection result. The user equipment sends, if the detection result indicates that the current TA has expired, at least one of a random access signal and a target notification message to a base station.
