MEASURING NEIGHBORING CELLS BY USER EQUIPMENT SERVED BY MASTER RADIO ACCESS NODE AND SECONDARY RADIO ACCESS NODE

摘要

There is provided updating neighboring cell information for a secondary radio access node controlled by a master radio access node. Neighboring cells are measured by user equipment served by the master radio access node and the secondary access node controlled by the master radio access node. Neighboring cell information is obtained. Neighboring cell information maintained in at least the secondary radio access node is updated on the basis of the obtained neighboring cell information.
