Abstract

[Object] To propose a mechanism which is capable of improving utilization efficiency of frequency resources in wireless communication. [Solution] A wireless communication device including: a processing unit configured to generate a first frame in which second frame transmission period information corresponding to a frequency is stored in a second region which is subsequent to a first region in which first frame transmission period information is stored; and a transmission unit configured to transmit the first frame. A wireless communication device including: a reception unit configured to receive a first frame in which second frame transmission period information corresponding to a frequency is stored in a second region which is subsequent to a first region in which first frame transmission period information is stored; and a transmission unit configured to stand by for transmission of a frame at a frequency based on the first frame transmission period information.

Claims (53)

1. A wireless communication device comprising:

circuitry configured to

generate a first frame in which second frame transmission period information corresponding to a plurality of frequencies is stored in a second region which is subsequent to a first region in which first frame transmission period information is stored;

transmit the first frame; and

receive a second frame in which second frame transmission period information corresponding to the plurality of frequencies is stored in a fourth region which is subsequent to a third region in which first frame transmission period information is stored, as a response to the first frame.

2. The wireless communication device according to claim 1 ,

wherein a plurality of pieces of the second frame transmission period information are stored in the first frame, and

the plurality of frequencies corresponding to the plurality of pieces of the second frame transmission period information are different from each other.

3. The wireless communication device according to claim 2 ,
