Abstract: Embodiments of the present disclosure provide a scheduling method and a base station. In a cell handover process, a target base station serving a target cell receives a random access request from a terminal, sends a random access response to the terminal according to the random access request, and proactively sends an uplink grant to the terminal after sending the random access response and prior to receiving a handover complete command from the terminal. By proactively sending the uplink grant, the target base station can perform uplink scheduling for UE before cell handover is completed, so as to reduce an uplink transmission latency caused by the cell handover.
