A multi-antenna transmitting apparatus wherein a relatively simple selection procedure can be used to reconcile the data transmission rate and the received data quality. When a transport signal, which is required to have a higher quality than other signals, is to be transmitted, a vector multiplexing part (105) reduces the number of transport beams (i.e., reduces the number of unique paths used for transmission), and further gives a higher priority to a unique vector belonging to a large unique value and uses that unique vector to vector multiplex the transport signal, thereby forming a transport beam (i.e., gives a higher priority to a signal, which is required to have a high quality, and transmits that signal by use of a unique path having a large path gain).
A communication method in a multi-antenna communication apparatus for determining transmission parameters using information obtained by communicating a known symbol between the multi-antenna communication apparatus and one communicating party, the method comprising:
