PROBABILISTIC MOBILITY LOAD BALANCING IN MULTI-BAND MOBILE COMMUNICATION NETWORK

A method performed by an electronic device of a wireless communication system, includes: receiving channel qualities and movements reports from a plurality of user equipments; based on the channel qualities and the movements reports, determining whether a load balancing index (LBI) is lower than a predetermined threshold; based on identifying that the LBI is lower than the predetermined threshold, determining an assignment matrix between the plurality of UEs and the plurality of operating bands by calculating minimized maximum band loads and minimized number of inter-frequency handovers (HOs); and transmitting a message to a first UE of the plurality of UEs, wherein the message indicates that the first UE is assigned to a first operating band of the plurality of the operating bands, based on the assignment matrix.
