Abstract (en)
[origin: WO2020164177A1] Example embodiments of the present disclosure relate to devices, methods, apparatuses and computer readable storage media of a primary cell change. In example embodiments, a network device transmits a set of pre-configurations to a terminal device via a first message. At least one pre-configuration in the set of pre-configurations is associated with a secondary cell in a set of secondary cells and is activated if the associated secondary cell is switched to be a primary cell. The network device transmits, to the terminal device via a separate second message, a switch indication for switching a secondary cell in the set of secondary cells to be a primary cell. In response to receiving a confirmation for the switching from the terminal device, the network device causes the at least one pre-configuration associated with the secondary cell to be activated.
