<p>When transmit signals to a plurality of receiving apparatuses are multiplexed using a plurality of antennas, the processing burden for determining an allocation of a weight vector to each receiving apparatus is reduced. A transmitting apparatus (10) multiplexes transmit signals to receiving apparatuses (20, 30, 40) according to weight vectors, and transmits the multiplexed transmit signals wirelessly using antennas (11a, 11b, 11c). Here, a controller (12) of the transmitting apparatus (10) first selects a first receiving apparatus and allocates a weight vector to it. Next, the controller (12) outputs, to a second receiving apparatus, data on candidates of a weight vector available in parallel with the weight vector allocated to the first receiving apparatus. Then, the controller (12) allocates the weight vector to the second receiving apparatus based on feedback data from the second receiving apparatus.</p> |
