WIRELESS COMMUNICATION DEVICE

摘要

[Object] To improve the reliability by using an acknowledgement response while using radio resources efficiently in multicast transmission over wireless transmission.;[Solution] A plurality of wireless communication devices included in a multicast group, when receiving a data frame, transmit simultaneously an acknowledgement response of multicast using spatial multiplexing in response to an acknowledgement request from a transmission source. On the other hand, a wireless communication device of the transmission source decomposes the acknowledgement responses simultaneously received into the original individual acknowledgement responses and restores them using signal processing based on information on a channel with each wireless communication device of a transmission destination.

1. A wireless communication device comprising:
a communication unit configured to communicate wirelessly with a plurality of slave stations under control; and a controller configured to control data transmission with each of the slave stations via the communication unit, wherein the controller allows the communication unit serving as a master station to perform multicast transmission to the plurality of slave stations and to request an acknowledgement for the multicast transmission from the slave station, and the communication unit performs a process of receiving an acknowledgement response simultaneously transmitted from the plurality of slave stations.
