摘要： A wireless communication system in which a base station apparatus having a plurality of transmission antennas and one or more terminal apparatuses communicate with each other is provided with at least two methods of a first feedback method and a second feedback method regarding propagation path information at the time of reception. In accordance with a communication condition between the base station apparatus and the terminal apparatus, or the function of the terminal apparatus, the terminal apparatus performs feedback by one of the two methods of the first feedback method and the second feedback method. The base station apparatus performs spatial multiplexing transmission on the basis of the propagation path information that has been fed back. Thus, in a system in which CSI is fed back for MIMO transmission, desired transmission characteristics can be efficiently obtained.

摘要： When signals received by receiving antennas included in each terminal are subjected to MMSE combining, it is configured that each terminal is able to grasp position of desired signal in signal vector obtained after combining. A base station 100 receives by a receiving antenna 23 from the terminal apparatus channel state information between a transmitting antenna 16 and spatial multiplexing object antennas included in each terminal apparatus. A transmit weight calculation unit 19 calculates a transmit weight for performing spatial multiplexing transmission to the terminal apparatus based on the channel state information. Transmit weight multiplication unit s 12 and 18 multiplies an information signal addressed to each terminal apparatus to be performed spatial multiplexing by the transmit weight. A signal multiplexing unit 13 multiplexes the information signal multiplied by the transmit weight and an information to specify the information signal that needs to be demodulated by each terminal apparatus.

摘要： An adhesive layer, an insulating layer and a copper foil are laminated together on both surfaces of a metallic base material by way of for example thermal press molding. In this case, openings (window holes) are formed in opposed positions on a portion of the adhesive layer. A circuit pattern is formed by etching on the copper foil in this state, followed by an external shape machining step of executing separation treatment reaching the metallic base material in predetermined positions including the openings. After that, a part of the insulating layer is cut off along the edge of the opening to obtain a circuit board with the end of the metallic base material exposed.
