A method in a network node for adapting a Secondary cell, SCell, command to a user equipment, UE, is provided. The SCell command is one of a setup and release command. The network node adapts the SCell command by one of advancing and delaying the timing of sending said SCell command with respect to a start of a transmission occasion of disjoint signals on which one of the UE and the network node is performing at least one of a measurement, the disjoint signal is a signal that is not used for performing the measurement in every subframe, a data transmission, the disjoint signal is a signal that is not used for transmitting the data in every subframe, and a data reception, the disjoint signal is a signal that is not used for receiving the data reception in every subframe.
