摘要

A wireless communication device that includes circuitry that receives a physical layer (PHY) header from a first wireless communication device belonging to a first wireless communication network different from a second wireless communication network to which the wireless communication device belongs, and controls transmission power on a basis of allowance signal information obtained in reception of the PHY header, and the PHY header includes the allowance signal information in which allowance of another signal for signal reception in a first destination wireless communication device which is a destination of a frame subsequent to the PHY header is specified.

說明書

in a case in which a signal is received from the first destination wireless communication device, the distance includes the distance between the self-device and the first destination wireless communication device which is estimated on a basis of reception of the signal from the first destination wireless communication device.

(12)

The wireless communication device according to any one of (6) to (11), in which

the information obtained in the reception of the PHY header and used to control the transmission power includes at least one of the modulation scheme information, transmission power information, and the allowance signal information included in the PHY header and reception signal strength in regard to the PHY header.

(13)

The wireless communication device according to any one of (6) to (12), in which,

in a case in which transmission power requested from a second destination wireless communication device which is a destination of a signal that the self-device is to transmit is equal to or less than the transmission power decided by the control unit, the communication unit transmits the signal with the requested transmission power.

(14)

The wireless communication device according to (13), in which

transmission of the signal with the requested transmission power includes transmission of a signal during a transmission stop time set in reception of a signal from the first wireless communication device.

(15)

A wireless communication device including:
