Abstract: Methods and arrangements in a base station and a User Equipment are provided. The methods and arrangements relates to the scenario when the UE is handed over from a source base station to a target base station in a handover scenario, and wherein the target base station may not support functionalities which the source base station and the UE support. The method in the UE comprises receiving (501) a configuration message from the target base station via the source base station, configuring (502) the UE based on the received configuration message from the target base station by searching (503) for a second field in an information element of the received configuration message. The presence/non-presence or a value of the second field is indicative of how to manage a configured first functionality associated with an optional first field, wherein the configured first functionality may not be supported by the target base station.

Abstract: Embodiments are disclosed which improve the accuracy of measurement quantities obtained based on filtered measurements, by enabling filter memory reset events triggered by specific configuration and/or reconfiguration commands. According to some embodiments, a method for obtaining a measurement quantity is provided. The measurement quantity is based on a filtered reference signal (RS) measurement value. The method is executed in a wireless device, e.g. a user equipment (UE). According to the method, the wireless device receives (1410) a filter reset indication. In response to the indication, the wireless device resets (1420) one or more RS measurement filters. The wireless device then obtains (1430) a new filtered RS measurement value, and obtains (1440) the measurement quantity based on the new filtered RS measurement value.
