Abstract: Example embodiments of the present disclosure relate to devices, methods, apparatuses and computer readable storage media for a primary secondary cell (PSCell) change failure. In example embodiments, a master network device receives, from a source secondary network device, a first request for a change of a terminal device from the source secondary network device to a target secondary network device. The master network device receives, from the source secondary network device, an identification of a source PSCell operated by the source secondary network device and serving the terminal device prior to the first request. The master network device further receives, from the terminal device, an indication of a radio link failure of the terminal device in a PSCell and transmits the indication of the radio link failure to the source secondary network device along with the identification of the source PSCell.
