1. A method performed by a User Equipment (UE), the method comprising:
receiving from a network node, a higher layer configuration comprising a set of SpCell configurations, to be configured in the UE,
receiving from the network node a higher layer configuration comprising one or more Transmission Configuration Indication (TCI) state configurations to be configured in the UE, wherein the TCI state configurations are associated to one or more SpCells;
while being in connected state, receiving a lower layer signaling from a network node, wherein the lower layer signaling comprises an indication that indicates any one out of:
the one or more SpCells, wherein the one or more SpCells comprised in the set of SpCell configurations, to be any one or more out of: activated or deactivated, and
one or more TCI states comprised in the one or more TCI state configurations,
when receiving an indication indicating one or more TCI states, wherein the one or more TCI states is associated with a configured SpCell that is currently not activated, performing deactivation of a currently activated SpCell, and activation of an SpCell associated with the indicated one or more TCI states.
