Abstract
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.
Claims7
A wireless communication device comprising:
- circuitry configured to
- receive a trigger signal from an access point device, the trigger signal including trigger notification information;
- include, in a physical layer (PHY) header, the trigger notification information;
- and
- transmit the PHY header including the trigger notification information, the trigger notification information being used to control transmission power in another device belonging to a second wireless communication network different from a first wireless communication network to which the access point device and the wireless communication device belong, wherein
- the trigger notification information includes allowance signal information in which allowance of another signal for signal reception in the access point device which is a destination of a frame subsequent to the PHY header is specified.
An access point device comprising:
- circuitry configured to
- transmit a trigger signal to a wireless communication device, the trigger signal including trigger notification information, the trigger notification information being used to control transmission power in another device belonging to a second wireless communication network different from a first wireless communication network to which the access point device and the wireless communication device belong;
- and
- receive a frame subsequent to a physical layer (PHY) header from the wireless communication device, the PHY header including the trigger notification information, wherein
- the trigger notification information includes allowance signal information in which allowance of another signal for signal reception in the access point device which is a destination of the frame subsequent to the PHY header is specified.
A wireless communication method executed in a wireless communication device, the method comprising:
- receiving a trigger signal from an access point device, the trigger signal including trigger notification information;
- including, using circuitry, in a physical layer (PHY) header, the trigger notification information;
- and
- transmitting the PHY header including the trigger notification information, the trigger notification information being used to control transmission power in another device belonging to a second wireless communication network different from a first wireless communication network to which the access point device and the wireless communication device belong, wherein
- the trigger notification information includes allowance signal information in which allowance of another signal for signal reception in the access point device which is a destination of a frame subsequent to the PHY header is specified.
A wireless communication method executed in an access point device, the method comprising:
- transmitting, at a transmitter, a trigger signal to a wireless communication device, the trigger signal including trigger notification information, the trigger notification information being used to control transmission power in another device belonging to a second wireless communication network different from a first wireless communication network to which the access point device and the wireless communication device belong, and
- receiving a frame subsequent to a physical layer (PHY) header from the wireless communication device, the PHY header including the trigger notification information, wherein
- the trigger notification information includes allowance signal information in which allowance of another signal for signal reception in the access point device which is a destination of the frame subsequent to the PHY header is specified.
