摘要： A base station, a mobile station and a retransmission control method for enabling communication to be more efficiently performed. In a communication system comprising a base station (100) and a mobile station (200), a time period required for the retransmission of a transport packet to complete is determined, and a retransmission control is performed, based on the required time period, to change the order of executing the retransmission of the transport packet and a handover. In this way, when it is estimated that the retransmission will complete soon, the retransmission is caused to complete in a handover source system, thereby avoiding waste of communication resources used in the preceding transmission and retransmission processes. When it is estimated that the retransmission will continue for a while, the communication resources used in the preceding transmission and retransmission processes are wasted, but a more appropriate MCS can be assigned, in a handover destination system, so as to perform a retransmission, thereby enabling communication to be efficiently performed.

摘要： It is possible to surely improve the throughput in a handover area in the MIMO communication and increase the cell coverage. Channel estimation units (104-1, 104-2) perform a channel estimation by using a common pilot signal transmitted from each base station device and acquire a channel matrix for each cell. Singular value decomposition processing units (105-1, 105-2) perform singular value decomposition processing by using a channel matrix corresponding to each cell. Channel capacity calculation units (106-1, 106-2) compare a singular value for each path to a threshold value and calculate the number of singular values above a predetermined threshold value as the channel capacity. A cell selection unit (107) compares the channel capacity sizes and selects a base station device corresponding to a greater channel capacity.

摘要： Disclosed are a wireless communication method, a wireless communication base station device, and a wireless communication terminal device that dynamically switch the transmission slot of an SRS of each terminal within a cell while suppressing an increase in the number of signaling bits. A terminal (100) and a base station (200) are each provided with a table wherein FH flags for SRS and transmission power data of each slot are mapped to two-bit notification bits. In this table, transmission power data indicating SRS transmission by slot 1 and slot 2 and FH flags are mapped, and an FH flag is not mapped to transmission power data indicating SRS transmission by slot 1 or slot 2. The base station (200) notifies the terminal (100) of the FH flag data and the SRS transmission power data by means of transmitting scheduling data containing the notification bits to the terminal (100).

摘要： A terminal and a communication method thereof whereby, even in a case of employing the asymmetric carrier aggregation system and further employing the MIMO transmission method for upstream channels, the error characteristic of control information can be prevented from being degraded. In the terminal (200), a transport signal forming unit (212) forms transport signals by arranging, based on a arrangement rule, ACK/NACK and CQI in a plurality of layers. According to the arrangement rule, an error detection result is arranged, on a priority basis, in a layer that is different from a layer in which the channel quality information is arranged. In this way, the puncturing of CQI using ACK/NACK can be minimized, with the result that the error characteristic of control information can be prevented from being degraded.
