BASE STATION DEVICE AND MOBILE COMMUNICATION METHOD
First Claim
1. A base station device, which performs radio communication with a user equipment using a plurality of carriers in a mobile communication system, comprising:
- a simultaneous communication instruction unit configured to instruct the user equipment to perform simultaneous communication using the plurality of carriers, whereinthe simultaneous communication instruction unit is configured to decide whether to give an instruction to perform the simultaneous communication using the plurality of carriers based on at least one of path loss between the user equipment and the base station device, downlink radio quality, and downlink channel state information,wherein the simultaneous communication instruction unit is configured to decide whether to give an instruction to perform the simultaneous communication using the plurality of carriers based on the difference of path loss among carriers.

Abstract
When multicarrier transmission is performed, the degradation of a downlink signal is reduced. A base station device eNB according to the present invention includes a simultaneous communication instruction unit 14 configured to instruct the user equipment UE to perform simultaneous communication using the plurality of carriers, wherein the simultaneous communication instruction unit 14 is configured to decide whether to give an instruction to perform the simultaneous communication using the plurality of carriers based on at least one of path loss between the user equipment UE and the base station device eNB, downlink radio quality, and downlink channel state information.
