Abstract  Abstract

This disclosure relates to a method for efficiently performing power control in a situation where a UE is connected to both a master base station and a secondary base station. The master base station determines the power allocation ratio of the power used by the UE for uplink transmissions to the master base station and the secondary base station, and calculates parameters P EMAX, MeNB And P EMAX, SeNB , and transmits this parameter to the secondary base station / UE for use in power control. Further, the master base station receives the support of the UE to update the power allocation ratio, that is, the UE transmits the information on the path loss in the second radio link to the secondary base station, preferably to the secondary base station To the master base station by transmitting a virtual power headroom report for the second wireless link. From the virtual power headroom report, the master base station derives information about the path loss in the second wireless link.
