Wireless communication device and wireless communication method
According to one embodiment, a wireless communication terminal includes: at least one antenna; a receiver; a transmitter; a communication processor; a network processor; and a memory. The transmitter is configured to transmit a first frame including information to specify a plurality of frequency components. The communication processor is configured to determine whether or not a second frame is received via each of the plurality of frequency components. The transmitter is configured to transmit a third frame including first information concerning a first value range which is used to determine whether to respond to the first frame, the first value range being dependent on a number of frequency components via which the second frame has been received. The first frame or the third frame includes the first data cached in the memory or information based on the first data.
1. A wireless communication device comprising:
a transmitter configured to transmit a first frame including information to specify a plurality of random access resource units wherein the first frame is a trigger frame;
a receiver configured to receive one or more second frames via at least one of the plurality of random access resource units; and
controlling circuitry configured to manage a minimum value and a maximum value used in transmission of the one or more second frames, wherein
the transmitter is configured to transmit a third frame including the minimum value and the maximum value,
the minimum value and the maximum value are used in a wireless communication terminal, which receives the first frame and determines whether to transmit the second frame via one of the plurality of random access resource units, to restrict a minimum range and a maximum range of a first value range for updating the first value range,
the first value range is used to determine a first value which is used to determine whether to transmit in one of the one or more random access resource units in the wireless communication terminal,
the first value is randomly selected from the first value range, and
wherein the first value range is updated based on a result status of success or failure of transmitting the one of the one or more second frames in the wireless communication terminal.
2. The wireless communication device according to claim 1 , wherein the third frame is a beacon frame or a probe response frame.
3. The wireless communication device according to claim 1 , further comprising at least one antenna.
4. A wireless communication method comprising:
transmitting a first frame including information to specify a plurality of random access resource units wherein the first frame is a trigger frame;
receiving one or more second frames via at least one of the plurality of random access resource units; and
managing a minimum value and a maximum value used in transmission of the one or more second frames,
transmitting a third frame including the minimum value and the maximum value, wherein
the minimum value and the maximum value are used in a wireless communication terminal, which receives the first frame and determines whether to transmit the second frame via one of the plurality of random access resource units, to restrict a minimum range and a maximum range of a first value range for updating the first value range,
the first value range is used to determine a first value which is used to determine whether to transmit in one of the one or more random access resource units in the wireless communication terminal,
the first value is randomly selected from the first value range, and
wherein the first value range is updated based on a result status of success or failure of transmitting the one of the one or more second frames in the wireless communication terminal.
