Abstract:
1. A base station apparatus that performs main normal transmission if a communication-target terminal unit exists in the cell thereof and that can perform cooperative transmission when the communication-target terminal unit exists in another cell, the base station apparatus comprising: a reference signal ID code determining means that determines the ID code of a reference signal specific to the terminal unit; a reference signal generating means that generates the reference signal based on the determined ID code; and, a transmitting means that transmits a signal including the reference signal, wherein the reference signal generating means generates a reference signal for cooperative transmission to be used when the communication-target terminal unit exists in a cooperative transmission cell such as to be different from the reference signal for main transmission that is used by the base station apparatus for performing main transmission, and the transmitting means transmits the generated reference signal for cooperative transmission to the terminal.
