Description

Technical Field

[0001] The present invention relates to a communication device, a communication method, and a program for performing wireless communication. Background Art

[0002] In recent years, wireless local area network (hereinafter referred to as WLAN) technology has achieved an improvement in data communication throughput, and various technical developments are currently being actively conducted.

[0003] The IEEE 802.11 series of standards, including IEEE 802.11a / b / g / n / ac / ax, is considered one of the WLAN communication standards. The latest standard, IEEE 802.11ax, adopts orthogonal frequency division multiple access (OFDMA) technology. This not only achieves a peak throughput of up to 9.6 gigabits per second (Gbps), but also improves transmission rates in congested conditions (see Patent Document 1). The IEEE 802.11be standard is under research as a successor standard, aiming to further improve throughput.

[0004] As a method of achieving the throughput improvement expected by IEEE 802.11be, expansion of the maximum value of the frequency bandwidth of radio waves from the conventional 160 MHz to 320 MHz has been studied.

[0005] In addition, a technique called preamble puncturing has been studied to efficiently use a frequency band. If some target frequency bandwidths are unavailable, this technique uses the remaining frequency bandwidths except for the unavailable frequency bandwidths for communication.

[0021] Exemplary embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0022] Figure 1 An example of a network configuration according to the present exemplary embodiment is illustrated. Figure 1 In the wireless network 101, there is an access point (hereinafter referred to as AP) 102 and a plurality of stations (hereinafter referred to as STAs) 103, 104, and 105. For example, the AP 102 is an access point compliant with the IEEE 802.11 standard and includes a group owner (hereinafter referred to as GO) compliant with the Wi-Fi Direct standard. When the AP 102 is the GO, the plurality of stations (STAs 103 to 105) are also referred to as clients.

[0023] The AP 102 configures the wireless network 101 conforming to the IEEE 802.11 standard and transmits a beacon including identification information of the wireless network. Figure 1 The dotted line surrounding the wireless network 101 indicates the coverage of the signal transmitted by the AP 102. The AP 102 can communicate with the STAs 103, 104, and 105 within the dotted line. The AP 102 may have a relay function.

[0024] When AP 102 receives a Probe Request message transmitted from a STA, AP 102 transmits a Probe Response message in response. The Probe Response message includes identification information of wireless network 101. Examples of fragments of identification information of wireless network 101 include a Service Set Identifier (hereinafter referred to as SSID).

[0025] The AP 102 also communicates with the STAs 103 to 105 according to a wireless communication method conforming to the IEEE 802.11be standard. The AP 102 establishes wireless connections with the STAs 103 to 105 through a predetermined association process.

[0026] Figure 1 For example, the following discussion regarding the positional relationship between various communication devices is applicable to a network including multiple communication devices in a large area.

[0027] Figure 2 The figure illustrates the hardware configuration of each of AP 102 and STAs 103 to 105, which are communication devices according to this exemplary embodiment. AP 102 according to this exemplary embodiment may be not only an AP-only device such as a so-called wireless local area network (LAN) router, but also a device such as a smartphone, camera, printer, or projector. STAs 103 to 105 may also be devices such as smartphones, cameras, printers, or projectors. A single communication device may have both AP and STA functions.

[0028] As an example of a hardware configuration, each of the AP 102 and the STAs 103 to 105 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 .

[0029] The storage unit 201 includes both or either one of at least one read-only memory (ROM) and at least one random access memory (RAM), and the at least one read-only memory and the at least one random access memory are used to store various information such as programs for performing various operations (described below) and communication parameters for wireless communication. The storage unit 201 can include memory (ROM and RAM) and storage media such as a floppy disk, a hard disk, an optical disk, a magneto-optical (MO) disk, a compact disc read-only memory (CD-ROM), a compact disc recordable (CD-R), a magnetic tape, a non-volatile memory card, and a digital versatile disc (DVD).

[0030] The control unit 202 includes, for example, at least one processor such as a central processing unit (CPU) or a microprocessing unit (MPU), an application-specific integrated circuit (ASIC), a digital signal processor (DSP), and a field-programmable gate array (FPGA). CPU is the abbreviation for central processing unit, and MPU is the abbreviation for microprocessing unit. The control unit 202 controls the entire device by executing the program stored in the storage unit 201. The control unit 202 can control the entire device through the cooperation of the program stored in the storage unit 201 and the operating system (OS).

[0031] The control unit 202 controls the functional unit 203 to perform image capture, printing, projection, and other predetermined processing. The functional unit 203 is a hardware component that enables the AP 102 or each STA to perform predetermined processing. For example, when the AP 102 or each STA is a camera, the functional unit 203 is an imaging unit that performs image capture processing. For example, when the AP 102 or each STA is a printer, the functional unit 203 is a printing unit that performs printing processing. For example, when the AP 102 or each STA is a projector, the functional unit 203 is a projection unit that performs projection processing. The data processed by the functional unit 203 can be data stored in the storage unit 201 or data received through communication with other APs or STAs via the communication unit 206 (described below).

[0032] Input unit 204 receives various operations from the user. Output unit 205 outputs various types of data to the user. The data output by output unit 205 includes at least one of a screen display, audio output from a speaker, and a vibration output. Input unit 204 and output unit 205 can be implemented as a single module, such as a touch panel.

[0033] Communication unit 206 is a so-called wireless LAN chip that controls wireless communications compliant with the IEEE 802.11 standard series and controls Internet Protocol (IP) communications. According to this exemplary embodiment, communication unit 206 can perform communication processing compliant with at least the IEEE 802.11be standard. Communication unit 206 is a processing device that generates physical layer (PHY) protocol data units (PPDUs) compliant with the IEEE 802.11 standard series. Alternatively, communication unit 206 is a processing device that receives and processes PPDUs generated by other devices. According to this exemplary embodiment, communication unit 206 generates or processes various PPDUs (described below). Communication unit 206 controls antenna 207 to transmit and receive wireless communication signals for wireless communication. AP 102 or each STA communicates content such as image data, document data, and video data with other communication devices via communication unit 206. Each component of antenna 207 can receive signals in the sub-GHz frequency band (any of the 2.4, 5, and 6 GHz bands). Antenna 207 can physically include two or more antennas to perform multiple-input multiple-output (MIMO) communication.

[0034] Figure 3 The diagram shows a frequency band configuration used in wireless communications according to this exemplary embodiment. In the 2.4 GHz band used for wireless LANs, a frequency bandwidth of 20 or 40 MHz is suitable. Similarly, in the 5 GHz band used for wireless LANs, a frequency bandwidth of 20, 40, 80, or 160 MHz is suitable.

[0035] Furthermore, according to the present exemplary embodiment, a frequency band of 5.925 to 7.125 GHz (so-called 6 GHz band) is applicable. In the 6 GHz band, in addition to frequency bandwidths of 20, 40, 80, and 160 MHz, a bandwidth of 320 MHz is also applicable. Figure 3 The figure shows an example of a frequency band configuration. Frequency bands other than the above-mentioned frequency bands can be applied, and a bandwidth of 320 MHz can also be applied in the 5 GHz frequency band.

[0036] Figures 4 to 6The diagram illustrates an example of a radio frame (i.e., the frame format of an Extremely High Throughput (EHT) Single-User (SU) Physical Layer Protocol Data Unit (PPDU), an EHT Multi-User (MU) PPDU, and an EHT Extended Range (ER) PPDU) compliant with the IEEE 802.11be standard according to this exemplary embodiment. EHT stands for Extremely High Throughput. These PPDUs include a preamble portion of the physical layer (PHY), a data field, and a packet extension portion. The preamble of the PPDU includes fields 401 to 407 (501 to 508 or 601 to 607). Various data in the Medium Access Control (MAC) layer and higher-level layers are stored in data fields 408, 509, and 608. Figures 4 to 6 An example of a frame format is shown. Each PPDU may include fields other than the following fields, and some fields may be omitted. The order of the fields is not limited to Figures 4 to 6 The order shown in .

[0037] Information included in each PPDU includes a short training field (STF), a long training field (LTF), and a signal field (SIG).

[0038] The header of the PPDU includes a legacy short training field (L-STF) 401 , a legacy long training field (L-LTF) 402 , and a legacy signal (L-SIG) 403 that are backward compatible with the IEEE 802.11a / b / g / n / ac / ax standards.

[0039] The L-STF 401 is used for PHY frame signal detection, automatic gain control (AGC), and timing detection. The L-LTF 402 is used for high-precision frequency / time synchronization, channel state information (CSI) acquisition, etc. The L-SIG 403 is used to transmit control information including information related to communication rate and length.

[0040] Legacy devices compliant with IEEE 802.11a / b / g / n / ac / ax standards are able to decode data in the various legacy fields mentioned above.

[0041] Figure 4 The EHT SU PPDU in FIG. 1 is a PPDU used for single-user communication (between AP 102 and a single STA). The EHT SU PPDU includes a L-STF 401, an L-LTF 402, an L-SIG 403, a repeated legacy signal (RL-SIG) 404, an extremely high throughput-signal-A (EHT-SIG-A) 405, an extremely high throughput-short training field (EHT-STF) 406, and an extremely high throughput-long training field (EHT-LTF) 407 as a preamble. The EHT SU PPDU also includes a data field 408 and a packet extension 409.

[0042] Figure 6 The EHT ER SU PPDU in the

[102] format is used in communications between the AP 102 and a single STA for extended range (when extending the communication range). The EHT ER SU PPDU includes an L-STF 601, an L-LTF 602, an L-SIG 603, an RL-SIG 604, an EHT-SIG-A 605, an EHT-STF 606, and an EHT-LTF 607 as a preamble. The EHT ER SU PPDU also includes a data field 608 and a packet extension 609. To extend the communication range, the EHT ER SU PPDU differs from the EHT SU PPDU in that the applicable MCS (modulation scheme and coding rate) is restricted.

[0043] As shown in Table 1 and Table 2, EHT-SIG-A 405 and EHT-SIG-A 605 included in the EHT SU PPDU and the EHT ER SU PPDU include information on EHT-SIG-A1 and EHT-SIG-A2 required to receive the PPDU.

[0044] According to this exemplary embodiment, information about the frequency bandwidth to be used and the preamble puncturing is indicated by the bandwidth field of EHT-SIG-A1. For example, a value of 0 in the bandwidth field indicates the use of a 20 MHz bandwidth, a value of 1 indicates the use of a 40 MHz bandwidth, a value of 2 indicates the use of an 80 MHz bandwidth, a value of 3 indicates the use of a 160 MHz bandwidth, and a value of 4 indicates the use of a 320 MHz bandwidth. These values ​​indicate that the preamble puncturing pattern will not be used. A value of 5 in the bandwidth field indicates that only the secondary 20 MHz is punctured in the 80 MHz preamble puncturing. A punctured frequency band means that the frequency band will not be used. A value of 6 in the bandwidth field indicates that either of the two 20 MHz of the secondary 40 MHz is punctured in the 80 MHz preamble puncturing. A value of 7 in the bandwidth field indicates that only the secondary 20 MHz is punctured in the 160 (or 80+80) MHz preamble puncturing. A value of 8 in the Bandwidth field indicates that at least one 20 MHz band, in addition to the primary 40 MHz band, is punctured in the 160 (or 80+80) MHz preamble. A value of 9 in the Bandwidth field indicates that only the secondary 20 MHz band is punctured in the 320 MHz preamble. A value of 10 in the Bandwidth field indicates that either of the two 20 MHz bands of the secondary 40 MHz band are punctured in the 320 MHz preamble. A value of 11 in the Bandwidth field indicates that at least one 20 MHz band, in addition to the primary 80 MHz band, is punctured in the 320 MHz preamble. To indicate this information, at least 4 bits are allocated to the Bandwidth field of the EHT-SIG-A1. The above correspondence between the Bandwidth field values ​​and the allocation of punctured frequency bands is intended to be considered an example. Any allocation other than the above applies as long as it relates to the 320 MHz bandwidth. The name, bit position, and size of each field are not limited to the values ​​shown in Tables 1 and 2. Similar information may be stored using different field names, orders, and sizes.

[0061] Figure 5 The EHT MU PPDU is a PPDU used for multi-user communication (between an AP and multiple STAs). The EHT MU PPDU includes an L-STF 501, an L-LTF 502, an L-SIG 503, an RL-SIG 504, an EHT-SIG-A 505, an EHT-SIG-B 506, an EHT-STF 507, and an EHT-LTF 508 as a preamble. The EHT MU PPDU also includes a data field 509 and a packet extension 510.

[0062] As shown in Table 3 and Table 4, the EHT-SIG-A 505 includes information on EHT-SIG-A1 and EHT-SIG-A2 required to receive the PPDU.

[0063] According to this exemplary embodiment, information regarding the frequency bandwidth to be used and preamble puncturing is indicated by the Bandwidth field of the EHT-SIG-A1. For example, a Bandwidth field value of 0 indicates the use of a 20 MHz bandwidth, a Bandwidth value of 1 indicates the use of a 40 MHz bandwidth, a Bandwidth value of 2 indicates the use of an 80 MHz bandwidth, a Bandwidth value of 3 indicates the use of a 160 MHz bandwidth, and a Bandwidth value of 4 indicates the use of a 320 MHz bandwidth. These values ​​indicate that the preamble puncturing pattern will not be used. A Bandwidth field value of 5 indicates that only the secondary 20 MHz is punctured in the 80 MHz preamble puncturing. A punctured frequency band means that the frequency band will not be used. A Bandwidth field value of 6 indicates that either of the two 20 MHz of the secondary 40 MHz is punctured in the 80 MHz preamble puncturing. A Bandwidth field value of 7 indicates that only the secondary 20 MHz is punctured in the 160 (or 80+80) MHz preamble puncturing. A Bandwidth field value of 8 indicates that at least one 20 MHz other than the primary 40 MHz is punctured in the 160 (or 80+80) MHz preamble puncturing. A value of 9 in the Bandwidth field indicates that only the secondary 20 MHz is punctured in the 320 MHz preamble puncturing. A value of 10 in the Bandwidth field indicates that one of the two 20 MHz of the secondary 40 MHz is punctured in the 320 MHz preamble puncturing. A value of 11 in the Bandwidth field indicates that at least one 20 MHz other than the primary 80 MHz is punctured in the 320 MHz preamble puncturing. To indicate this information, at least 4 bits are allocated to the Bandwidth field of the EHT-SIG-A1. The above correspondence between the values ​​of the Bandwidth field and the allocation of the punctured frequency band is considered an example. As long as it is related to the 320 MHz bandwidth, allocations other than the above allocations apply. The name, bit position, and size of each field are not limited to the values ​​shown in Tables 1 and 2. Similar information may be stored using different field names, orders, and sizes.

[0064] As described above, the EHT SU PPDU, EHT ER SU PPDU, and EHT MU PPDU compliant with the IEEE 802.11be standard can implement preamble puncturing by specifying a frequency band exceeding 160 MHz. In the above description, the information related to the bandwidth field is the same for the EHT SUPPDU, EHT ER SU PPDU, and EHT MU PPDU. However, the correspondence between the value of the bandwidth field and the allocation of the punctured frequency band may differ between the SU PPDU and the MU PPDU. For example, when preamble puncturing is performed for a MU PPDU (multi-user communication), the communication frequency band may be allocated to different users (STAs) for each frequency bandwidth in units of 20 MHz. For example, in the case of a MU PPDU (multi-user communication), the number of punctured frequency bands may be greater than that in the case of a SU PPDU (single-user communication), and the corresponding value of the bandwidth field may be defined. This can increase the degree of freedom in using frequency bands in multi-user communication compared to single-user communication.

[0077]

[0078] (Variation)

[0079] In the above example, information related to preamble puncturing is indicated by the bandwidth field of the EHT-SIG-A1. Furthermore, 4 bits are allocated to the bandwidth field of the EHT-SIG-A1 to indicate when a 320 MHz frequency bandwidth is used. In the following example, 3 bits are allocated to the bandwidth field of the EHT-SIG-A1, and the EHT-SIG-A3 field is added separately. These fields indicate information related to preamble puncturing.

[0080] A value of 0 in the Bandwidth field of the EHT-SIG-A1 indicates the use of a 20 MHz frequency bandwidth. A value of 1 in the Bandwidth field of the EHT-SIG-A1 indicates the use of a 40 MHz frequency bandwidth. A value of 2 in the Bandwidth field of the EHT-SIG-A1 indicates the use of an 80 MHz frequency bandwidth. A value of 3 in the Bandwidth field of the EHT-SIG-A1 indicates the use of a 160 MHz frequency bandwidth. A value of 4 in the Bandwidth field of the EHT-SIG-A1 indicates the use of a 320 MHz frequency bandwidth. Values ​​0 to 4 in the Bandwidth field of the EHT-SIG-A1 indicate no preamble puncturing. A value of 5 in the Bandwidth field of the EHT-SIG-A1 indicates the use of an 80 MHz frequency bandwidth and the use of preamble puncturing. A value of 6 in the Bandwidth field of the EHT-SIG-A1 indicates the use of a 160 MHz frequency bandwidth and the use of preamble puncturing. A value of 7 in the Bandwidth field of the EHT-SIG-A1 indicates the use of a 320 MHz frequency bandwidth and the use of preamble puncturing. In addition, in case that the value of the bandwidth field of the EHT-SIG-A1 is 5 to 7, the EHT-SIG-A3 shown in Table 5 will be included in the EHT-PPDU. Figure 5 The names, digit positions, and sizes of each field in the _FIELD_ TABLE are intended to be examples. Different names, positions, and sizes may be used as long as similar information is indicated.

[0081] The EHT-SIG-A3 shown in Table 5 includes a Preamble Puncture field, which indicates the frequency bandwidth to which the preamble is punctured. The Preamble Puncture field in Table 5 is 16 bits long and is sequentially associated with a 20 MHz bandwidth, starting at bit position B0. When the 20 MHz frequency band is used, the corresponding bit is set to 0. Otherwise, i.e., to perform puncture, the corresponding bit is set to 1. The definition of 0 and 1 for each bit can be reversed. More specifically, in Table 5, the frequency band to be used is represented in a bitmap format.

[0082] For example, when using an 80 MHz frequency bandwidth and puncturing only the secondary 20 MHz, the value of the Bandwidth field of the EHT-SIG-A1 is 5. For the preamble puncturing field of the EHT-SIG-A3, only the B1 bit is set to 1, and the other bits are set to 0. The bitmap may have a variable length depending on the frequency bandwidth specified by the Bandwidth field of the EHT-SIG-A1. More specifically, the length of the bitmap may be 4 bits for an 80 MHz frequency bandwidth, 8 bits for a 160 MHz frequency bandwidth, and 16 bits for a 320 MHz frequency bandwidth. In this case, for the frequency bandwidth specified by the Bandwidth field of the EHT-SIG-A1, excess high-order bits may be unused or reserved.

[0083] [Table 8]

[0084] Table 5

[0085]

[0086] As another variation, instead of the example in Table 5, the frequency bands subjected to preamble puncturing may be indicated as follows. More specifically, a value of 0 in the preamble puncturing field of the EHT-SIG-A3 indicates that all frequency bandwidths are used, i.e., preamble puncturing is not performed. A value of 1 in the preamble puncturing field of the EHT-SIG-A3 indicates that the lowest frequency bandwidth, 20 MHz, is punctured. A value of 2 in the preamble puncturing field of the EHT-SIG-A3 indicates that 20 MHz of the frequency bandwidth from the lowest 20 Hz to 40 MHz is punctured. A value of 3 in the preamble puncturing field of the EHT-SIG-A3 indicates that 20 MHz of the frequency bandwidth from the lowest 40 Hz to 60 MHz is punctured. The value of the preamble puncturing field of the EHT-SIG-A3 may be defined as above. However, the above examples may be other methods.

[0087] As described above, according to this exemplary embodiment and each of the variations, even when a 320 MHz frequency bandwidth is used for wireless LAN communications, preamble puncturing can be performed appropriately. The AP 102 or each STA can generate the EHT-SIG-A field in the wireless LAN PPDU frame to perform appropriate preamble puncturing. By transmitting these PPDU frames between the AP 102 and each STA, preamble puncturing can be performed appropriately in wireless LAN communications between the AP 102 and each STA.
