  • Patent number: 10498502
    Abstract: This disclosure relates a method and a base station for network sharing using carrier aggregation. The base station of a multi-carrier system comprises a multiple of cells, where each cell corresponds to a carrier that is associated with a PLMN. The base station receives (302, S-424, S-516, S-616) a UE request with information of a UE (402, 502, 602), where a first cell of said multiple of cells corresponds to a first carrier. The base station determines (304, S-428, S-520, S-626) based on base station settings and/or UE information, whether an other carrier associated with a different PLMN is available to said UE. If so, the base station sends (306, S-430, S-440, S-524, S-530) a resource configuration message destined for said UE (402, 502, 602), enabling said UE to configure said other carrier as a SCC. Better coverage, peak rates and capacity, without suffering from the drawbacks of existing RAN sharing techniques, are provided.
