Conditional change of primary cell of secondary cell group

Abstract

There is provided an apparatus comprising at least one processor; and at least one memory including computer program code, the at least one memory and the computer program code configured to, with the at least one processor, cause the apparatus at least to perform: receiving, from a network node, configuration for a conditional change of primary cell of a secondary cell group; performing evaluation of one or more conditions for the conditional change; selecting a primary cell based on the evaluation; determining an activation status to be applied for a target secondary cell group associated with the selected primary cell based on at least one of the following: activation status of a source secondary cell group, the received configuration, pre-configuration; executing the conditional change to the selected primary cell; and applying the determined activation status for the target secondary cell group associated with the selected primary cell.
