PROBLEM TO BE SOLVED: To provide a terminal, a base station device, a communication system, and a communication method which can report efficient reception quality information, when transmitting control information, i.e., the reception quality information, by using a channel for data transmission.SOLUTION: A terminal 102 reports the reception quality information by the same spatial multiplex method as that of data, when the reception quality information is reported non-periodically, and reports the reception quality information by a spatial multiplex method independent from that of data, when the reception quality information is reported periodically. When extracting the reception quality information reported together with the data from the terminal device, a base station device 101 extracts the reception quality information as the same spatial multiplex method as that of data, when the reception quality information is reported non-periodically, and extracts the reception quality information as a spatial multiplex method independent from that of data, when the reception quality information is reported periodically. |
