Abstract

There is provided a wireless communication device that includes: a receiving unit that receives a first transmission frame via a receiving antenna, the first transmission frame being transmitted from a communication partner; a response-frame generating unit that generates a first response frame indicating reception of the first transmission frame, based on the first transmission frame received via the receiving antenna; a transmitting unit that transmits the generated first response frame via a transmitting antenna; a determining unit that determines whether or not the same first transmission frame is retransmitted from the communication partner; and an antenna control unit that changes a beam pattern of the transmitting antenna, when the same first transmission frame is retransmitted from the communication partner.

Claims6

Dependent claims

A wireless communication device, comprising:

a receiver, which, in operation, receives a first transmission frame;
control circuitry, which, in operation,
generates a first response frame indicating reception of the first transmission frame, based on the received first transmission frame;
determines whether a sequence number of the received first transmission frame matches a previously stored sequence number;
and
when the sequence number of the received first transmission frame matches the previously stored sequence number, updates a current antenna transmission beam pattern;
and
a transmitter, which, in operation, transmits the first response frame using the updated antenna transmission beam pattern.
