Abstract: A method and a base station for data transmission are disclosed. The data transmission method includes: when a semi-persistent resource is in an activated state and time alignment (TA) data needs to be sent, sending the TA data to a user equipment (UE) by using the semi-persistent resource. In embodiments of the present application, the base station sends the TA data by using the semi-persistent resource, thereby reasonably using the resource and reducing scheduling and allocation of PDCCH and PDSCH resources by the base station. This not only saves resources, but also reduces time that the base station takes to process TA data, and increases system resource utilization and cell throughput.
