USER TERMINAL, RADIO COMMUNICATION SYSTEM, AND RADIO COMMUNICATION METHOD

摘要

PROBLEM TO BE SOLVED: To appropriately control antenna selection in a user terminal even when the user terminal connects with a plurality of radio base stations by applying dual connectivity (DC).SOLUTION: A user terminal communicates with a plurality of radio base stations each setting a cell group comprising one or more cells. The user terminal includes: a transmission unit for transmitting UL signals to each cell group; and a control unit for controlling the selection of a transmission antenna port used for the transmission of the UL signals. The control unit selects the same transmission antenna port for cells included in the same cell group.SELECTED DRAWING: Figure 3
