A battery diagnosis apparatus determines whether a battery may be reused and includes a data obtaining device configured to output a perturbation signal, a signal regulating device configured to generate a current by applying the perturbation signal to a battery and performing feedback of a current signal output from the battery, and a noise canceling device configured to cancel noises of the current signal and a voltage signal received from the battery. The data obtaining device outputs the perturbation signal while changing a frequency, obtains an impedance spectrum based on the noise-canceled current signal and voltage signal for each frequency, and determines whether to reuse the battery based on the obtained impedance spectrum.

Method and apparatus for a user equipment (UE) supporting dual connectivity (DC) with a master node and a secondary node are disclosed. According to these, the UE receives first configuration information from the master node and second configuration information from the secondary node. The UE applies the first configuration information first. And, the UE transmits a new configuration request message to the secondary node, if the UE cannot apply the second configuration information after applying the first configuration information.
