Classification: CPC H  Y | IPC H

Claim 0:
1. An access point device comprising:
circuitry configured to
transmit an acknowledgement request frame for data transmission to a first station device and a second station device; and
receive respective acknowledgement response frames simultaneously transmitted from the first station device and the second station device, wherein
the circuitry is further configured to
specify, by the acknowledgement request frame, an encoding scheme of training signals of the acknowledgement response frames used to form a format capable of separating the acknowledgement response frames transmitted simultaneously from the first station device and the second station device using calculation;
acquire first information on a first propagation path between the first station device and the access point device from a first training signal of the training signals transmitted from the first station device in accordance with the encoding scheme;
acquire second information on a second propagation path between the second station device and the access point device from a second training signal of the training signals transmitted from the second station device in accordance with the encoding scheme; and
separate the acknowledgement response frames received simultaneously from the first station device and the second station device on a basis of the first information and the second information.
