摘要： It is possible to effectively perform feedback in a communication system in which base station devices cooperatively communicate. A feedback information generation unit 208 has a function of adjusting the amount of information used for representing a channel estimated value which is output from a channel estimation unit 206, depending on each base station device. In other words, among a feedback information amount used for representing a channel estimated value between the mobile station device and the base station device connected to the mobile station device, and a feedback information amount used for representing a channel estimated value between the mobile station device and a base station device other than the base station device connected to the mobile station device, the feedback information amount used for representing one type of channel estimated value is adjusted so as to be less than the feedback information amount used for representing the other type of channel estimated value.

摘要： In a wireless communication system in which a base station and a terminal communicate with each other, the terminal switches connection destinations efficiently. The terminal includes a positional information measurement unit, notifies the base station of positional information, and based on connection base station information transmitted from the base station, generates a synchronization signal of the connection base station information, and communicates with the connection base station. The terminal transmits terminal information to a first base station, and starts communication with a second base station based on information notified from the first base station. The terminal information is positional information, which is obtained by the GPS or a positioning reference signal.

摘要： A reference signal generation unit 105 generates a reference signal and inputs it to resource-mapping units 106-1 to 106-T. There may be a plurality of types of reference signals depending on purposes. In the present disclosure, only a user-specific demodulation reference signal (DM-RS) is described. The resource-mapping units 106-1 to 106-T map DM-RS's and an input from the precoding unit 104 to a resource such that they are orthogonal between transmitting antennas and between transmission points.

摘要： In a communication system that includes a first base station, a second base station, and at least one terminal that makes a connection to the second base station, a connection destination of the terminal that makes a connection to the second base station is efficiently switched. The terminal that makes a connection to the second base station determines received quality of each of a neighboring base station that is positioned in the neighborhood of the second base station and the second base station, and notifies a macro cell base station and the second base station of the received quality. Furthermore, the first base station or the second base station determines whether or not the terminal has to perform handover, based on the received quality. In a case where the handover has to be performed, the first base station determines the connection destination of the terminal, based on the received quality notified from the terminal, and provides a handover instruction.

摘要： A channel estimation unit estimates channel state information to or from a base station device. A feedback information generation unit performs a decomposition process for the channel state information and thereby acquires first decomposition information that includes plural singular values and second decomposition information that includes plural right singular vectors respectively associated with the plural singular values. The feedback information generation unit mutually replaces portions of the plural singular values, thereby acquires first replacement information, and further acquires second replacement information based on the first replacement information and the plural right singular vectors. The feedback information generation unit performs a conversion process for the second replacement information and thereby acquires second conversion information. A radio transmission unit notifies the base station device of the second conversion information.
