Abstract: A wireless communication device includes: a transmission unit that transmits a request frame indicating a request for traffic information; a receiving unit that receives a response frame in which the traffic information is stored; and a control unit that controls transmission of a frame related to permission of transmission directed to a first wireless communication device that is identified on the basis of the traffic information stored in the received response frame and that is permitted to perform multiple access. A wireless communication device includes: a receiving unit that receives a request frame indicating a request for traffic information; a transmission unit that transmits a release frame is which the traffic information is stored in response to the received request frame; and a control unit that controls transmission of a frame related to the traffic information on the basis of a communication parameter related to multiple access.

Abstract: There is provided a wireless device configured to perform both multi-user spatial multiplex communication and single user communication with a communication device. The wireless device is configured to set a first waiting time for the single user communication, and count the first waiting time in a period in which a second waiting time for the multi-user spatial multiplex communication is counted. The wireless device then transmits data through the single user communication after the first waiting time expires.
