Abstract
A communication device includes transmitting means for transmitting a signal in one or more frequency bands of a frequency channel including a plurality of frequency bands, identifying means for identifying occupancy of the plurality of frequency bands, and control means for controlling transmission power for transmitting the signal from the transmitting means, on the basis of an identification result obtained by the identifying means.
Claims20
A communication apparatus comprising:
- one or more processors;
- and
- one or more memories including instructions that, when executed by the one or more processor, cause the communication apparatus to:
- transmit a trigger frame including information about a resource unit in which another communication apparatus transmits a signal and an information element to be used to determine transmission power for the other communication apparatus to transmit a signal in the resource unit;
- and
- receive the signal transmitted from the other communication apparatus by the transmission power determined based on communication quality between the communication apparatus and the other communication apparatus and the information element, in response to transmission of the trigger frame,
- wherein the communication apparatus receives the signal transmitted from the other communication apparatus by first transmission power in a case where the communication quality is first quality, and the communication apparatus receives the signal transmitted from the other communication apparatus by second transmission power higher than the first transmission power in a case where the communication quality is second quality lower than the first quality.
A communication system including a first communication apparatus and a second communication apparatus, the communication system comprising:
- a determination unit configured to determine transmission power for the first communication apparatus to transmit a signal in a resource unit, based on communication quality between the first communication apparatus and the second communication apparatus and information element to be used to determine the transmission power for the first communication apparatus to transmit the signal in the resource unit;
- a first transmission unit configured to transmit a trigger frame including information about the resource unit in which the first communication apparatus transmits the signal and the information element;
- a second transmission unit configured to transmit a signal by the transmission power determined by the determination unit in response to reception of the trigger frame transmitted by the first transmission unit;
- and
- a receiving unit configured to receive the signal transmitted by the second transmission unit.
A control method for controlling a communication apparatus comprising:
- transmitting a trigger frame including information about a resource unit in which another communication apparatus transmits a signal and an information element to be used to determine transmission power for the other communication apparatus to transmit a signal in the resource unit;
- and
- receiving the signal transmitted from the other communication apparatus by the transmission power determined based on communication quality between the communication apparatus and the other communication apparatus and the information element, in response to transmission of the trigger frame,
- wherein the communication apparatus receives the signal transmitted from the other communication apparatus by first transmission power in a case where the communication quality is first quality, and the communication apparatus receives the signal transmitted from the other communication apparatus by second transmission power higher than the first transmission power in a case where the communication quality is second quality lower than the first quality.
A communication method for communication between a first communication apparatus and a second communication apparatus, the communication method comprising:
- determining transmission power for the first communication apparatus to transmit a signal in a resource unit, based on communication quality between the first communication apparatus and the second communication apparatus and information element to be used to determine the transmission power for the first communication apparatus to transmit the signal in the resource unit;
- transmitting a trigger frame including information about the resource unit in which the first communication apparatus transmits the signal and the information element;
- transmitting a signal by the determined transmission power in response to reception of the transmitted trigger frame;
- and
- receiving the transmitted signal.
A non-transitory storage medium storing instructions that, when executed by at least one processor, configures a communication apparatus to perform a control method, the control method comprising:
- transmitting a trigger frame including information about a resource unit in which another communication apparatus transmits a signal and an information element to be used to determine transmission power for the other communication apparatus to transmit a signal in the resource unit;
- and
- receiving the signal transmitted from the other communication apparatus by the transmission power determined based on communication quality between the communication apparatus and the other communication apparatus and the information element, in response to transmission of the trigger frame,
- wherein the communication apparatus receives the signal transmitted from the other communication apparatus by first transmission power in a case where the communication quality is first quality, and the communication apparatus receives the signal transmitted from the other communication apparatus by second transmission power higher than the first transmission power in a case where the communication quality is second quality lower than the first quality.
A non-transitory storage medium storing instructions that, when executed, control a communication system including a first communication apparatus and a second communication apparatus to communicate according to a control method, the control method comprising:
- determining transmission power for the first communication apparatus to transmit a signal in a resource unit, based on communication quality between the first communication apparatus and the second communication apparatus and information element to be used to determine the transmission power for the first communication apparatus to transmit the signal in the resource unit;
- transmitting a trigger frame including information about the resource unit in which the first communication apparatus transmits the signal and the information element;
- transmitting a signal by the determined transmission power in response to reception of the transmitted trigger frame;
- and
- receiving the transmitted signal.
