  • Methods and apparatuses for handling the configuration of measurements to be performed by a user equipment in a wireless communication network
    Patent number: 12231968
    Abstract: A method performed by a first base station, is described. The first base station determines a change in one or more measurements to be performed by a UE. The measurements are associated with a first set of frequencies. The first base station also transmits a first message to a second base station comprising information regarding which frequencies in the first set are to be changed. The first base station and the second base station serve the UE. A method performed by the second base station is also described whereby the second base station receives the first message. In a method performed by the UE, the UE receives, from the first base station, a configuration message configured to specify the measurements to perform and a measurement gap configuration. The UE then takes the measurements based on the configuration message.
