<p>Disclosed are a a method for uplink data transmission, an evolved node B (eNB), a user equipment (UE), a computer program, and storage medium. The method comprises: the eNB sends uplink synchronization indication signaling to the UE, wherein the signaling indicates that the UE needs to perform the uplink synchronization on the first carrier; the eNB receives the uplink synchronization reference signal sent from the UE on the first carrier, and based on the signal, calculates the Time Advance (TA) value which the UE needs for uplink data transmission on the first carrier, and sends the TA value to the UE on the second carrier; the eNB sends the UE, on the third carrier, the uplink resource allocation information of the first carrier, wherein the information includes the sub-frame number of the first carrier, and the information of the time-frequency resource position and size for the uplink transmission in the sub-frame corresponding to the first carrier, so that the UE transmits uplink data to the eNB on the first carrier. The present invention implements the uplink synchronization and data transmission on the carriers without the control information.</p> |
