Abstract (en)

[origin: WO2022141491A1] Method, device and computer program product for wireless communication are provided. A method includes: receiving, by a wireless communication terminal, a radio resource control, RRC, message comprising conditional reconfiguration from a wireless communication node; wherein the conditional reconfiguration comprises at least one candidate cell configuration, and one or more execution conditions for each candidate cell; wherein the candidate cell configuration comprises a first indication of a secondary cell group, SCG, activation state of the candidate cell; selecting, by the wireless communication device, based on one or more execution conditions, a target cell, to apply a cell configuration of the target cell in the conditional reconfiguration; and determining, by the wireless communication device, the SCG activation state of the target cell, according to the first indication of an SCG activation state of the target cell.
