Embodiment Construction
[0036] The present invention will be described in detail below in conjunction with the accompanying drawings. It should be noted that the described embodiments are for the purpose of illustration only, and do not limit the scope of the present invention. The various numerical values described are not intended to limit the present invention, and these numerical values can be appropriately modified according to the needs of those of ordinary skill in the art.
[0037] Cellular MIMO OFDMA System
[0038] Figure 2 shows an example of a cellular MIMO system. Multiple antennas are installed on both the BTS end of the base station and the UE end of the user, and the user communicates with the base station. Figure 3 shows an example of a multi-cell OFDMA system, showing a multi-cell MIMO OFDMA system employing a hexagonal cell shape. There are six adjacent cells around each cell, each base station covers a cell, and the radio network controller RNC manages all the base stations...
