MOBILE STATION DEVICE AND COMMUNICATION PARTNER SELECTION METHOD |
摘要 |
<p>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.</p> |
