A wireless communication apparatus comprising a communication unit that transmits a reference signal; a first multiplying unit, the other end of communication is performed based on the received reference signals to determine the weight of the first transmission weight multiplier.
[Objective] To provide a radio communication apparatus, a wireless communication system, a wireless communication method and a program. [Solution] A wireless communication apparatus comprising: a communication unit that transmits a reference signal; a first multiplying unit, the other end of communication is performed based on the received reference signals to determine the weight of the first transmission weight multiplier, and a second multiplying unit, the other end of which performs communication based on the reference signal received to determine the weight of the second transmission weight multiplier. After determining the first transmission weight, the reference signal weighted by the communication unit transmits a first reference signal by a transmission weight is obtained.
