Japanese Patent JP6118842
Kind Code:
B2
Abstract:
A user apparatus configured to perform communication with a base station in a mobile communication system that supports carrier aggregation, including: transmission means configured to transmit, to the base station, the number of layers for each of component carriers that form the carrier aggregation as information of downlink MIMO capability; and reception means configured to receive, from the base station, the number of layers that is used for determining a bit width of a rank indicator for each of the component carriers that form the carrier aggregation.
