摘要： During a period of parallel-like radio communication with two or more first base stations, the first base station designates a second base station correlated with one of the two or more first base stations, and temporarily suspends the radio communication in accordance with a first communications standard to issue, to a mobile station, a request of measurement for the designated second base station. The first base station receives a result of the measurement for the designated second base station. The first base station notifies the mobile station of a handover from the first communications standard to a second communications standard, and also notifies the mobile station of a request for starting a coordination mode in which the two or more second base stations including the designated second base station establish communication with the mobile station in coordination with each other.

摘要： A mobile communication device includes antennas, transmitting units, and receiving units. A baseband processing unit of the mobile communication device transmits data signals to a base station device through a receiving unit and an antenna that are selected based on an instruction received from the base station device. The baseband processing unit transmits reference signals to the base station device through the transmitting units and the antennas while preventing transmission frequencies of the reference signals from overlapping one another. A baseband processing unit of the base station device transmits, to the mobile communication device based on qualities of the received reference signals, a signal indicating information concerning which of the antennas and the transmitting units of the mobile communication device are used for transmitting the data signals, the signal also indicating information concerning whether or not to make the transmitting units and the antennas share transmission of the reference signals. Thus, interferences due to degradation of communication quality and to an increase in the number of reference signals can be prevented.
