A wireless communication device, comprising: a wireless communication unit configured to perform wireless communication with other wireless communication device in accordance with an IEEE 802.11 standard; and a control unit configured to control the wireless communication unit so that the wireless communication unit includes schedule information in a header portion of physical layer protocol data unit PPDU defined in the IEEE 802.11 standard and transmits the schedule information to the other wireless communication device, the schedule information relating to orthogonal frequency-division multiple access OFDMA wherein the header portion includes, as the schedule information, segmentation pattern identification information indicating one segment pattern to be used among one or more segmentation patterns, the segmentation pattern being a pattern used to divide one or more subcarriers forming a frequency channel into one or more frequency segments, and wherein the segmentation pattern identification information is used in common by users multiplexed by the OFDMA, characterized in that the header portion includes a flag information that is used to identify whether communication with the other wireless communication device is performed using OFDMA, a length information that is used to identify a number of OFDMA-related fields, and one or more resource block information, each of the resource block information including at least a user ID information and Modulation and Coding Scheme MCS information, and wherein the segmentation pattern identification information is represented by a first number of bits, the first number of bits being set depending on frequency bandwidth for transmitting the PPDU and the first number of bits to be set being different between a first case in which the frequency bandwidth corresponds to 40 MHz, a second case in which the frequency bandwidth corresponds to 80 MHz, and a third case in which the frequency bandwidth corresponds to 80+80 MHz. a wireless communication unit configured to perform wireless communication with other wireless communication device in accordance with an IEEE 802.11 standard; and a control unit configured to control the wireless communication unit so that the wireless communication unit includes schedule information in a header portion of physical layer protocol data unit PPDU defined in the IEEE 802.11 standard and transmits the schedule information to the other wireless communication device, the schedule information relating to orthogonal frequency-division multiple access OFDMA wherein the header portion includes, as the schedule information, segmentation pattern identification information indicating one segment pattern to be used among one or more segmentation patterns, the segmentation pattern being a pattern used to divide one or more subcarriers forming a frequency channel into one or more frequency segments, and wherein the segmentation pattern identification information is used in common by users multiplexed by the OFDMA, characterized in that the header portion includes a flag information that is used to identify whether communication with the other wireless communication device is performed using OFDMA, a length information that is used to identify a number of OFDMA-related fields, and one or more resource block information, each of the resource block information including at least a user ID information and Modulation and Coding Scheme MCS information, and wherein the segmentation pattern identification information is represented by a first number of bits, the first number of bits being set depending on frequency bandwidth for transmitting the PPDU and the first number of bits to be set being different between a first case in which the frequency bandwidth corresponds to 40 MHz, a second case in which the frequency bandwidth corresponds to 80 MHz, and a third case in which the frequency bandwidth corresponds to 80+80 MHz.
