Assignee: SONY GROUP CORPORATION
Field: Digital communication (Electrical engineering)
Classification: CPC H  Y | IPC H

Claim 3:
4. A station device comprising:
circuitry configured to
receive an acknowledgement request frame for data reception transmitted from the access point device to the station device, the acknowledgement request frame requesting an acknowledgement response frame; and
transmit the acknowledgement response frame simultaneously with another acknowledgement response frame transmitted from another station device after a lapse of a predetermined time from reception of the acknowledgement request frame transmitted from the access point device, wherein
the circuitry is configured to transmit the acknowledgement response frame using an encoding scheme of a training signal of the acknowledgement response frame specified from the access point device by the acknowledgement request frame, the encoding scheme of the training signal of the acknowledgement response frame being used to form a format capable of separating the acknowledgement response frame and the another acknowledgement response frame transmitted simultaneously from the station device and the another station device using calculation, and wherein
the circuitry is configured to encode the training signal in accordance with the encoding scheme and transmit the encoded training signal.
