[0025] The embodiments will now be described in detail with reference to the accompanying drawings. Note that the following embodiments are not intended to limit the scope of the claimed invention. Multiple features are described in the embodiments, but there is no requirement for all such features to be required for the invention, and multiple such features can be appropriately combined. Furthermore, in the drawings, the same reference numerals are used for the same or similar configurations, and repeated descriptions thereof are omitted.

[0026] [System Structure]

[0027] Figure 1 This refers to the wireless communication system according to this embodiment. Figure 1 The wireless communication system shown is a wireless network including an access point (AP) 102 and multiple STAs (stations / terminal devices) 103, 104, and 105 as communication devices. Besides its relay function, the AP 102 has the same functions as a terminal device and is therefore a form of terminal device. The AP 102 can communicate with each STA 103-105 using a wireless communication method conforming to the IEEE 802.11be standard. STAs 103-105 located within circle 101, which represents the range of the signals (radio frames) transmitted by the AP 102, can communicate with the AP 102.

[0028] This embodiment assumes that AP 102 and each STA 103-105 can communicate with each other according to the IEEE 802.11be standard. AP 102 establishes a wireless link with each STA 103-105 via a predetermined association process, etc. AP 102 and each STA 103-105 can communicate with each other in the 2.4GHz, 5GHz, and 6GHz frequency bands. The frequency bands used by AP 102 and each STA 103-105 are not limited to these; for example, different frequency bands such as the 60GHz band can be used. AP 102 and each STA 103-105 can communicate with each other using bandwidths of 20MHz, 40MHz, 80MHz, 160MHz, 240MHz, and 320MHz.

[0029] The AP 102 and each of the STAs 103 to 105 can perform OFDMA communication. For example, the AP 102 can implement multi-user (MU) communication that multiplexes signals to multiple users (STAs). In OFDMA communication, some of the divided frequency bands (RUs (Resource Units)) are allocated to respective STAs without overlapping each other, and the carriers allocated to the respective STAs are orthogonal to each other. Thus, the AP 102 is able to communicate with multiple STAs simultaneously.

[0030] The AP 102 and each of the STAs 103 to 105 can transmit / receive management frames that comply with the IEEE 802.11 series standards, such as MAC (Medium Access Control) frames. More specifically, the management frames indicate each of a beacon frame, a probe request / response frame, and an association request / response frame. In addition to these frames, disassociation frames, authentication frames, deauthentication frames, and action frames are also referred to as management frames. The beacon frame is a frame that notifies network information. The probe request frame is a frame that requests network information, and the probe response frame is a response to the probe request frame, which is a frame that provides network information. The association request frame is a frame that requests connection, and the association response frame is a response to the association request frame, which is a frame that indicates permission or an error of connection. The disassociation frame is a frame for disconnecting connection. The authentication frame is a frame for authenticating the counterpart device. The deauthentication frame is a frame for interrupting authentication of the counterpart device and performing disconnection of connection. The action frame is a frame for performing an additional function other than the above functions.

[0031] The AP 102 and the STAs 103 to 105 can be configured to perform MIMO (Multiple Input Multiple Output) communication. In this case, each of the AP 102 and the STAs 103 to 105 includes a plurality of antennas, and the transmission side transmits different signals from the respective antennas using the same frequency channel. The reception side simultaneously receives all the signals that arrive from a plurality of streams using a plurality of antennas, separates the signals of the streams, and decodes them. The AP 102 and each of the STAs 103 to 105 are able to transmit more data simultaneously by performing MIMO communication than in the case where MIMO communication is not performed. The AP 102 and the STAs 103 to 105 manage operation parameters (operation information) such as a communication bandwidth (frequency bandwidth) for wireless communication.

[0032] Note that each of the AP 102 and the STAs 103 to 105 supports the IEEE 802.11be standard. In addition to this, each of the AP 102 and the STAs 103 to 105 can support at least one of legacy standards that are standards defined before the IEEE 802.11be standard. The legacy standards indicate the IEEE 802.11a / b / g / n / ac / ax standards. Note that in the present embodiment, at least one of the IEEE 802.11a / b / g / n / ac / ax / be standards is referred to as an IEEE 802.11 series standard. Furthermore, in addition to the IEEE 802.11 series standards, each of the AP 102 and the STAs 103 to 105 can support other communication standards, such as NFC (Near Field Communication), UWB (Ultra Wide Band), Zigbee, or MBOA (Multiband OFDM Alliance). The UWB includes wireless USB, wireless 1394, and Winet. In addition, each of the AP 102 and the STAs 103 to 105 can support a communication standard of wired communication such as wired LAN.

[0033] [Arrangement of Communication Device]

[0034] Figure 2A An example of a hardware arrangement of the communication device (the AP 102 and the STAs 103 to 105) according to the present embodiment is shown. As an example of the hardware arrangement, the communication device includes a storage unit 201, a control unit 202, a function unit 203, an input unit 204, an output unit 205, a communication unit 206, and an antenna 207.

[0035] The storage unit 201 is formed of one or a plurality of memories such as a ROM (Read Only Memory) and a RAM (Random Access Memory), and stores a computer program for executing various operations (to be described later) and various information such as a communication parameter for wireless communication. Note that in addition to the memories such as the ROM or the RAM, a storage medium such as a floppy disk, a hard disk, an optical disk, a magneto-optical disk, a CD-ROM, a CD-R, a magnetic tape, a nonvolatile memory card, or a DVD can be used as the storage unit 201. The storage unit 201 can include a plurality of memories.

[0036] The control unit 202 is formed of one or more processors such as a CPU (Central Processing Unit) and an MPU (Micro Processing Unit), for example, and controls the communication apparatus by executing a computer program stored in the storage unit 201. Note that the control unit 202 can be configured to control the communication apparatus by cooperation of the computer program stored in the storage unit 201 and an OS (Operating System). The control unit 202 generates data or a signal (radio frame) to be transmitted in communication with other communication apparatuses. The control unit 202 can include a plurality of processors such as a multi-core processor, and control the communication apparatus by the plurality of processors.

[0037] In addition, the control unit 202 controls the functional unit 203 to perform wireless communication or predetermined processing such as image capturing, printing, or projection processing. The functional unit 203 is hardware of the communication apparatus for performing predetermined processing.

[0038] The input unit 204 accepts various operations from a user. The output unit 205 performs various outputs to the user via a monitor or a speaker. In the present example, the output of the output unit 205 can include display on the monitor, audio output through the speaker, and vibration output, for example. Note that the input unit 204 and the output unit 205 can be implemented by one module such as a touch panel. Furthermore, each of the input unit 204 and the output unit 205 can be integrated with the communication apparatus, or can be separated from the communication apparatus.

[0039] The communication unit 206 controls wireless communication compliant with the IEEE 802.11be standard. In the present embodiment, the communication unit 206 functions as a means for notifying (transmitting) operation information (to be described below) to other communication apparatuses. The communication unit 206 can control wireless communication compliant with other IEEE 802.11 sequence standards in addition to the IEEE 802.11be standard, or control wired communication through a wired LAN or the like. The communication unit 206 controls the antenna 207 to transmit / receive a signal (radio frame) for wireless communication generated by the controller 202. Note that if the communication apparatus supports an NFC standard or a Bluetooth standard in addition to the IEEE 802.11be standard, the communication unit 206 can control wireless communication compliant with these communication standards. If the communication apparatus is capable of performing wireless communication compliant with each of a plurality of communication standards, it can have an arrangement including a communication unit and an antenna supporting each communication standard, respectively, which are integrated. The communication apparatus transmits data such as image data, document data, or video data to other communication apparatuses via the communication unit 206. Note that the antenna 207 can be arranged separately from the communication unit 206, or can be configured as a module integrated with the communication unit 206.

[0040] The antenna 207 is an antenna that allows communication in the 2.4 GHz, 5 GHz, and 6 GHz bands. The communication device can include one antenna, or can include different antennas for each frequency band. If the communication device includes a plurality of antennas, it can include a communication unit 206 corresponding to each antenna.

[0041] Figure 2B An example of a functional arrangement of the control unit 202 of the communication device (AP 102 and STAs 103 to 105) according to the present embodiment is shown. As an example of the functional arrangement, the communication device includes an operation information decision unit 211, a frame generation unit 212, and a UI (user interface) control unit 213.

[0042] The operation information decision unit 211 decides operation information to be notified to other communication devices. The operation information will be described later. The frame generation unit 212 generates a frame for transmission (notification) to other communication devices. The UI control unit 213 performs control for accepting an operation of the communication device by a user of the communication device. For example, the UI control unit 213 sets, in the communication device, the content of the user input obtained from the input unit 204, for example, by transmitting the content to the operation information decision unit 211.

[0043] [Structure of EHT Operation Element]

[0044] In the present embodiment, the operation information can be notified to other communication devices using a management frame that complies with the IEEE 802.11 series standards. Note that other types of frames can be used for the notification of the operation information. Figure 3 An example of the structure of an EHT Operation Element 301, which is one of the information elements of the management frame, is shown.

[0045] With regard to the element ID field 302, the length field 303, and the element ID extension field 304, refer to the description of Table 1 below. The EHT Operation Information field 305 includes operation information for wireless communication. The operation information includes information for specifying the use frequency bandwidth or the like. The information of the use frequency bandwidth can be specified by a combination of the EHT Channel Center Frequency Segment field 307 (frequency information for wireless communication) included in the EHT Operation Information field 305 and the EHT Channel Width field 308 (frequency bandwidth information for wireless communication) contained in the control field 306. For example, if the EHT Channel Width field 308 has 0 and the EHT Channel Center Frequency Segment field 307 has 0, this can indicate that the use frequency bandwidth is 160 MHz or less. If the EHT Channel Width field 308 has 0 and the EHT Channel Center Frequency Segment field 307 has a value other than 0, this can indicate that the use frequency bandwidth is 240 MHz. If the EHT Channel Width field 308 has 1, this can indicate that the use frequency bandwidth is 320 MHz.

[0046] If the frequency bandwidth in use is 240MHz or more, the EHT channel center frequency segment field 307 indicates information about a channel for the 80MHz or 160MHz of the latter half / high frequency side (e.g., the 80MHz or 160MHz of the high frequency side containing the maximum frequency of the frequency bandwidth, or the secondary 80MHz or 160MHz). If the frequency bandwidth in use is 160MHz or less, the EHT channel center frequency segment field 307 can indicate 0. If the frequency bandwidth in use is 240MHz, the EHT channel center frequency segment field 307 is as follows. The EHT channel center frequency segment field 307 can indicate a channel value corresponding to the center frequency of the 160MHz of the high frequency side in the case of using the frequency bandwidth of 240MHz, a channel value corresponding to the center frequency of the 80MHz of the high frequency side in the case of using the frequency bandwidth of 160+80MHz, a channel value corresponding to the center frequency of the 160MHz of the high frequency side in the case of using the frequency bandwidth of 80+160MHz, and a channel value corresponding to the center frequency of the 80MHz of the high frequency side in the case of using the frequency bandwidth of 80+80+80MHz. In the case of using the frequency bandwidth of 320MHz, the EHT channel center frequency segment field 307 can indicate a channel value corresponding to the center frequency of the secondary 160MHz (e.g., the 160MHz of the high frequency side) in the case of using the frequency bandwidth of 160+160MHz, and a channel value corresponding to the lowest frequency of the secondary 160MHz in the case of using the frequency bandwidth of 320MHz.

[0047] Tables 1, 2, and 3 show actual examples of the components of the EHT Operating Element 301 explained above. Table 1 shows a description of each field of the EHT Operating Element 301, Table 2 shows a description of each subfield of the EHT Operating Information field 305, and Table 3 shows a description of each subfield of the Control field 306. The name of each field / subfield and the bit position and size are not limited to those described in the tables, and similar information can be stored with different field / subfield names and sizes in different orders.

[0056] [Description of the notification process for operation information]

[0057] Reference Figures 4 to 7 The notification process for operation information with the above structure is described. In this embodiment, operation information can be notified to other communication devices using a management frame conforming to the IEEE 802.11 series of standards. The operation information determination unit 211 determines / sets the operation information, the frame generation unit 212 generates a management frame including the operation information, and the generated frame is transmitted via the communication unit 206. Information about the frequency bandwidth and frequencies within the frequency bandwidth (e.g., information about the center frequency of the frequency band within the frequency bandwidth (channel value, etc.)) can be preset in the communication devices (AP 102 and STA 103-105). Alternatively, this information can be set in the communication device by input by the user of the communication device via the input unit 204, and the communication device can obtain this information by any method.

[0058] Now it will be explained as Figures 4 to 7 Common aspects. Management frames, defined by the conventional standard prior to the IEEE 802.11be standard, are used to notify information about the low-frequency side (first half) of the 160MHz band. Specifically, CCFS0, CCFS1, and channel width are values ​​notified to the communication device via management frames defined by the conventional standard. CCFS0 represents the channel value corresponding to the center frequency of the primary 80MHz band. CCFS1 represents the channel value corresponding to the center frequency of the secondary 80MHz band (or 160MHz obtained by combining it with the primary 80MHz band if it is adjacent to the primary 80MHz band). The channel width has a value indicating that the primary 80MHz and secondary 80MHz bands are adjacent to each other. Notification of CCFS0, CCFS1, and channel width can be made via VHT operation elements, HT operation elements, and 6GHz operation information, which are elements of management frames defined by the conventional standard. Note that... Figures 4 to 7 In this configuration, the channels are arranged to overlap each other every 5 MHz. Furthermore, reference... Figures 4 to 7 Equation (1) indicates the absolute value of the difference between CCFS0 and CCFS1, Equation (2) indicates the absolute value of the difference between CCFS1 and the center frequency band of the EHT channel (field 307), and Equation (3) indicates the value of the EHT channel width (field 308).

[0059] Figure 4is a diagram for explaining operation information notified to a communication apparatus in a case where a frequency bandwidth of 160+80MHz is used. As described above, the notification of CCFS0, CCFS1 and channel width as information of 160MHz in the low frequency side (the first half) in 160+80MHz is made by using a management frame defined by the conventional standard. In addition to the information of 160MHz in the low frequency side, the EHT channel center frequency segment (field 307) and the EHT channel width (field 308) explained above are used. At this time, the EHT channel center frequency segment indicates a channel value corresponding to the center frequency of 80MHz in the high frequency side, and the EHT channel width has a value of 0 indicating 240MHz. Figure 4 The formula (2) in indicates that 160MHz in the low frequency side (the first half) in 240MHz is not adjacent to 80MHz in the high frequency side (the latter half). In addition, based on the values of CCFS0, CCFS1 and the EHT channel center frequency segment, a frequency channel for 160MHz+80MHz can be notified.

[0060] Figure 5 is a diagram for explaining operation information notified to a communication apparatus in a case where a frequency bandwidth of 240MHz is used. As described above, the notification of CCFS0, CCFS1 and channel width as information of 160MHz in the low frequency side (the first half) in 160+80MHz is made by using a management frame defined by the conventional standard. In addition to the information of 160MHz in the low frequency side, the EHT channel center frequency segment (field 307) and the EHT channel width (field 308) explained above are used. At this time, the EHT channel center frequency segment indicates a channel value corresponding to the center frequency of 160MHz in the high frequency side, and the EHT channel width has a value of 0 indicating 240MHz. Figure 5 The formula (2) in indicates that 160MHz in the low frequency side (the first half) in 240MHz is adjacent to 80MHz in the high frequency side (the latter half). In addition, based on the values of CCFS0, CCFS1 and the EHT channel center frequency segment, a frequency channel for the frequency bandwidth of 240MHz can be notified.

[0061] Figure 6is a diagram for explaining operation information notified to a communication apparatus in a case where a frequency bandwidth of 80+160 MHz is used. As described above, the notification of CCFS0, CCFS1, and channel width, which are information of 80 MHz in the low frequency side (the first half) in 80+160 MHz, is made by using a management frame defined by the conventional standard. In addition to the information of 80 MHz in the low frequency side, the EHT channel center frequency segment (field 307) and the EHT channel width (field 308) explained above are used. At this time, the EHT channel center frequency segment indicates a channel value corresponding to the center frequency of 160 MHz in the high frequency side, and the EHT channel width has a value of 0 indicating 240 MHz. Figure 6 The formulas (1) and (2) in indicate that 80 MHz in the low frequency side (the first half) in 240 MHz is not adjacent to 160 MHz in the high frequency side (the latter half). In addition, based on the values of CCFS0, CCFS1, and the EHT channel center frequency segment, it is possible to notify the frequency channels for the frequency bandwidth of 80+160 MHz.

[0062] Figure 7 is a diagram for explaining operation information notified to a communication apparatus in a case where a frequency bandwidth of 80+80+80 MHz is used. As described above, the notification of CCFS0, CCFS1, and channel width, which are information of 160 MHz in the low frequency side (the first half) in 80+80+80 MHz, is made by using a management frame defined by the conventional standard. In addition to the information of 160 MHz in the low frequency side, the EHT channel center frequency segment (field 307) and the EHT channel width (field 308) explained above are used. At this time, the EHT channel center frequency segment indicates a channel value corresponding to the center frequency of 80 MHz in the high frequency side, and the EHT channel width has a value of 0 indicating 240 MHz. Figure 7 The formulas (1) and (2) in indicate that all of the frequency bandwidths of 80 MHz in 240 MHz are not adjacent to each other. In addition, based on the values of CCFS0, CCFS1, and the EHT channel center frequency segment, it is possible to notify the frequency channels for the frequency bandwidth of 80+80+80 MHz.

[0063] [Modified Example]

[0064] Table 4 shows a modification of the components of the EHT operation element 301 according to the above-described embodiment. If the EHT operation element 301 is used to specify the frequency bandwidth to be used, by extending the contents of the control field 306 as shown in Table 4, the frequency bandwidth can be easily specified. For example, if the EHT channel width field 308 (frequency bandwidth information for wireless communication) has 0, this can indicate that a frequency bandwidth of 160 MHz or less is used, if the EHT channel width field 308 has 1, this can indicate that a frequency bandwidth of 240 MHz is used, and if the EHT channel width field 308 has 2, this can indicate that a frequency bandwidth of 320 MHz is used. The names of each field / subfield and the bit positions and sizes are not limited to those described in the table, and similar information can be stored in different orders with different field / subfield names and sizes. If the EHT channel width field 308 is defined as shown in Table 4, in Figures 4 to 7 by changing the setting to EHT channel width field 308 = 1, the frequency bandwidth and the frequency channel can be notified.
