Embodiments of the disclosure generally relate to configuration of a random access preamble transmission. In response to receiving a handover request for handing over a terminal device from a source cell managed by a further network device to a target cell managed by the network device, a network device determines a configuration for a random access preamble transmission. The configuration indicates the number of times of transmission of the random access preamble from the terminal device. Afterwards, the network device transmits the configuration for the random access preamble transmission to the further network device.
