Abstract

A method can include receiving, by a first base station from a second base station, one or more first messages requesting the first base station to allocate resources for dual connectivity for a first wireless device. The method can also include sending, by the first base station to the second base station and based on determining that one or more conditions for reporting one or more measurements are satisfied for the first wireless device, one or more second messages that include one or more parameters indicating the one or more measurements for the first wireless device. The one or more conditions for reporting the one or more measurements can include, for example, a condition indicating to stop collecting the one or more measurements for the wireless device after a predetermined number of changes of primary secondary cells (PSCell) for the wireless device.
