Abstract
Some techniques for promptly assigning uplink dedicated resources in inter-site or inter-eNB carrier aggregation are disclosed. One aspect of the present invention relates to a user equipment including a transmission and reception unit configured to use radio resources to communicate with multiple base stations, a resource management unit configured to manage the radio resources and a cell type determination unit configured to determine a type of a cell providing the radio resources, wherein when the resource management unit detects occurrence of a release trigger for assigned uplink dedicated resources, the cell type determination unit determines a type of a cell providing the uplink dedicated resources and retains or releases the uplink dedicated resources depending on the determined cell type.
