[0017] The following description and accompanying drawings sufficiently illustrate specific embodiments to enable those skilled in the art to practice these embodiments. Other embodiments may include structural, logical, electrical, algorithmic, process, and other changes. Portions and features of some embodiments may be included in portions and features of other embodiments, or may replace portions and features of other embodiments. The embodiments set forth in the claims include all available equivalents of these claims.

[0018] Wi-Fi 8 is exploring ways to increase peak throughput and reduce latency. Some proposed solutions require significant hardware changes or may not directly improve throughput and latency. For example, adding a 60GHz band requires additional radios and suffers from coexistence issues with existing 802.11ad / 11ay devices. In another example, scheduled operation for low latency requires full control of the wireless medium for optimal performance, and its performance is questionable when there is interference from overlapping basic service sets (OBSS) and legacy devices. For wireless technology, bandwidth and the number of spatial streams are always the natural way to increase throughput and should be explored before turning to other complex technologies.

[0019] The IEEE 802.11 technical standard defines wireless communications, including the way Wi-Fi devices communicate the use of the bandwidth being used. For example, under the 802.11 standard, the current highest bandwidth communicated in 6GHz bandwidth communications for use in Wi-Fi is 320MHz. In 5GHz bandwidth Wi-Fi communications, the highest bandwidth communicated is 160MHz. In 5GHz, the only bandwidth option greater than 160MHz is 240MHz, for which there is no current signaling. In 6GHz, any communication over 500MHz is considered ultra-wide bandwidth (UWB) and is therefore subject to a power spectral density emission limit of 41.3dBm / MHz. This is significantly lower than the power spectral density emission limits in current Wi-Fi transmissions, such as 17dBm or 5dBm for Wi-Fi 6E low-power indoor devices. Therefore, classifying Wi-Fi as UWB is not a viable solution. In order to use bandwidths above 320 MHz in 6 GHz 802.11 communications, any use above 500 MHz (eg, using 640 MHz) triggers power spectral density limits, leaving 480 MHz as the only option above 320 MHz and below the 500 MHz limit.

[0020] For example, in the 5 GHz channelization defined by the 802.11ac technical standard, 160 MHz is the largest contiguous channel bandwidth that exists and can be communicated, even if the 5 GHz bandwidth includes portions greater than 160 MHz. It is not possible to communicate 320 MHz in a 5 GHz channel allocation (e.g., a 160 MHz + 160 MHz allocation) because the 160 MHz portions of the bandwidth are not contiguous. Therefore, it is currently not possible to communicate 240 MHz by communicating 320 MHz and puncturing the 80 MHz portion because there is no contiguous 320 MHz available for use.

[0021] Therefore, there is a need to communicate the use of bandwidths above 160 MHz in 5 GHz communications and above 320 MHz in 6 GHz communications in 802.11 Wi-Fi communications.

[0022] In one or more embodiments, in order to communicate the use of bandwidths above 160 MHz (e.g., 240 MHz) in 5 GHz communications and above 320 MHz (e.g., 480 MHz) in 6 GHz communications in 802.11 Wi-Fi communications, a puncturing option and a non-puncturing option may be implemented as described herein. In the puncturing option, with the aid of puncturing, bandwidth signaling may communicate a larger bandwidth, such as a 320 MHz bandwidth, where 80 MHz of the 320 MHz bandwidth is punctured to obtain 240 MHz. In the non-puncturing option, the 240 MHz bandwidth may be communicated directly.

[0023] According to the 802.11be 2.1 technical standard, when an extremely high throughput (EHT) station device (STA) in an EHT basic service set (BSS) operates in a 2.4 GHz band, a 5 GHz band, or a 6 GHz band, its operation is controlled by an EHT operation element (e.g., in an 802.11 beacon). The EHT operation element includes an EHT operation parameter field using one octet. When there is a disabled subchannel bitmap field, the EHT operation parameter field includes a disabled subchannel bitmap presence subfield set to 1. The EHT operation element also includes an EHT operation information field (e.g., using 0, 3, or 5 octets). The EHT operation information field includes a disabled subchannel bitmap of 0 or 2 octets. The disabled subchannel bitmap is a 16-bit subfield bitmap in which the lowest numbered bit corresponds to a 20 MHz subchannel located within the BSS bandwidth and having the lowest frequency in the set of all 20 MHz subchannels within the BSS bandwidth.

[0024] In one or more embodiments, the disabled subchannel bitmap may be modified so that the lowest numbered bit corresponds to a 20 MHz subchannel that is within the BSS bandwidth (identified in the EHT Operation Information field) and has the lowest frequency (identified in the EHT Operation Information field) in the set of all 20 MHz subchannels within the BSS bandwidth. Each subsequent bit in the bitmap corresponds to the 20 MHz subchannel of the next highest frequency. In this way, the BSS bandwidth announcement and subchannel bitmap design can be enhanced to facilitate higher bandwidth signaling without changing the meaning of the existing disabled subchannel bitmap. Currently, the disabled subchannel bitmap uses only 16 bits. Communication of 240 MHz will require the use of 12 bits instead of a 16-bit disabled subchannel bitmap, and communication of 480 MHz will require extending the disabled subchannel bitmap to 24 bits.

[0025] 802.11be 2.1 defines the control information subfield in the EHT operation management (OM) control subfield as including information related to bandwidth changes. The control information subfield format defined by 802.11ax includes a one-bit channel width extension field. The channel width extension field is combined with the channel width subfield in the OM control subfield to indicate the operating channel width supported by the STA for reception and transmission. For example, in 802.11be 2.1, 1 bit is reserved for the channel width extension subfield and bits 1-3 are used for the channel width subfield. In one or more embodiments, because the OM control subfield is addressed to each STA, the reserved bits can be used to communicate higher bandwidth to maintain the existing format of the OM control subfield.

[0026] In one or more embodiments, when the channel width field is present in the EHT operation information field and the channel width field indicates 320 MHz, the channel width extension field and the channel width subfield combination may indicate 480 MHz or 640 MHz. When the channel width field is present in the EHT operation information field and the channel width field indicates 160 MHz, the channel width extension field and the channel width subfield combination may indicate 240 MHz. For example, the channel width extension subfield may be set to 1, and the channel width subfield may be set to greater than or equal to 1 to indicate a higher bandwidth of 240 MHz, 480 MHz, or 640 MHz.

[0027] 802.11be 2.1 defines the EHT Operation Information field as also including a CCFS0 subfield and a CCFS1 subfield, each of which is one octet. In one or more embodiments, a new CCFS2 subfield (e.g., CCFS extension subfield) may be defined to indicate the center frequency of the high bandwidth (240 MHz, 480 MHz, or 640 MHz), and the field only exists when the channel width extension field is present.

[0028] In one or more embodiments, a disabled subchannel bitmap extension field may be defined and may only exist when a disabled subchannel bitmap is present. The disabled subchannel bitmap extension field may be defined and may exist when an access point (AP) communicates bandwidth puncturing of any subchannel outside the channel width identified in the EHT operation information field, and may be one or two bytes in size. The lowest numbered bit of the disabled subchannel bitmap extension field may correspond to a 20 MHz subchannel with the lowest frequency in a set of all 20 MHz subchannels outside the 1 BSS bandwidth identified in the EHT operation information field and outside the BSS bandwidth identified in the EHT operation information field. Each subsequent bit in the bitmap may correspond to a 20 MHz subchannel of the next higher frequency.

[0029] In one or more embodiments, a channel width extension field, a CCFS extension field, and a disabled sub-channel bitmap extension field may be included in a Wi-Fi 8 operation element.

[0030] The 802.11be 2.1 standard defines the U-SIG field (Universal Signal Field), which is defined to carry information required to interpret the EHT physical layer (PHY) protocol data unit (PPDU) and is designed to improve compatibility with the EHT preamble. Bits B3-B5 of the U-SIG field are used to communicate bandwidth. The values ​​6 and 7 of the three-bit combination are not used for any bandwidth, but in one or more embodiments, can be used to communicate bandwidths higher than 160 and 320 MHz. For example, bit value 6 can be used to indicate high bandwidth 1. Bit value 7 can be used to indicate high bandwidth 2. High bandwidths 1 and 2 can be 240 MHz, 480 MHz, or 640 MHz. Bit value 6 can be used for 240 MHz because there is only one 240 MHz in the 5 GHz bandwidth. 480-1 MHz and 480-2 MHz may be defined in the 6 GHz bandwidth, 640-1 MHz may be UNII 5, UNII 6, 6, 7, and 640-2 MHz may be UNII 6, 6, 7, UNII 7, 7, 8, UNII 8. In this way, there may be some bit reuse for values ​​6 and 7 in bits B3-B5 of the U-SIG field.

[0031] In one or more embodiments, in order to communicate higher bandwidth using puncturing, the AP may communicate the puncturing pattern to be used for the bandwidth. The puncturing may be 0 MHz, 80 MHz, 160 MHz puncturing, or 80 MHz + 160 MHz puncturing.

[0032] The 802.11be 2.1 standard defines the puncturing control information field of the U-SIG field of the EHT PPDU as whether the bandwidth portion of the PPDU is punctured (e.g., 20MHz bandwidth, 40MHz bandwidth, 80MHz bandwidth, 160MHz bandwidth, 320MHz bandwidth). For each bandwidth, there may be one or more puncturing modes, which define the 20MHz portion respectively. The 20MHz bandwidth and the 40MHz bandwidth may each have a puncturing mode for non-puncturing. The 80MHz bandwidth may have four puncturing modes for 20MHz puncturing and one non-puncturing mode. The 160MHz bandwidth may have eight puncturing modes for 20MHz puncturing, four puncturing modes for 40MHz puncturing, and one non-puncturing mode. The 320MHz bandwidth may have eight puncturing modes for 40MHz puncturing, four puncturing modes for 80MHz puncturing, twelve puncturing modes for simultaneous 80MHz and 40MHz puncturing, and one non-puncturing mode. In the puncturing pattern, 1 represents a non-punctured subchannel, and x represents a punctured subchannel.

[0033] In one or more embodiments, 160 MHz puncturing and simultaneous 160 MHz and 80 MHz puncturing may be defined for a 480 MHz bandwidth. The puncturing granularity may be 80 MHz, so each 1 or x value in the puncturing pattern may correspond to an 80 MHz portion. For 240 MHz, the puncturing granularity may be 40 MHz. The puncturing portions correspond to the existing defined channelization for 5 GHz and 6 GHz, so signaling does not need to be redefined for these bandwidths.

[0034] In one or more embodiments, the scrambler seed indication may be used to communicate higher bandwidths. The bandwidth signaling transmitter address (TA) in non-high throughput (HT) is used for a separate address frame and is only applicable to peers that support higher bandwidths of 240 MHz, 480 MHz, or 640 MHz. For older non-EHT devices, the primary 20 MHz channel may be overwritten, so it does not matter if it is communicated as any value in bits 0 or 1 in the scrambler seed. For EHT and non-Wi-Fi 8, there may be behavioral issues with 11 configurations that see the scrambler seed indication. Therefore, two options may be used for the scrambler: 1) reuse bits 0, 1, and 2 to communicate 240 MHz, 480 MHz, or 640 MHz. Option 2) may include reusing bits 0, 1, and 2 and adding bit 3.

[0035] In one or more embodiments, the uplink (UL) bandwidth indication in the trigger frame sent by the AP can use two bits in the special user information field for extension. In addition to the existing two-bit UL bandwidth extension field, the special user information field can also include a new two-bit UL bandwidth further extension. The UL bandwidth of all receiving STAs is in the common information field of the trigger frame, where the UL bandwidth extension is in the special user information field in the trigger frame. When the bandwidth of the HE TB PPDU (PPDU based on high-efficiency trigger) field value is 160MHz and the bandwidth of the EHT TB PPDU is 160MHz, the UL bandwidth extension field value 1 combined with the UL bandwidth further extension field value 0, 2, or 3 can pass the 240MHz bandwidth of the Wi-Fi 8TB PPDU. When the bandwidth of the HE TB PPDU (PPDU based on high-efficiency trigger) field value is 160MHz and the bandwidth of the EHT TB PPDU is 320MHz, the UL bandwidth extension field value 2 combined with the UL bandwidth further extension field value 2 or 3 can pass the 480MHz bandwidth of the Wi-Fi 8TB PPDU. When the bandwidth of the HE TB PPDU (PPDU based on high efficiency trigger) field value is 160MHz and the bandwidth of the EHT TB PPDU is 320MHz, the UL bandwidth extension field value 3 combined with the UL bandwidth further extension field value 2 or 3 can transmit the 480MHz bandwidth of the Wi-Fi 8TB PPDU.

[0036] In one or more embodiments, the following changes to 802.11 may be implemented to communicate 240 MHz or 480 MHz bandwidth:

[0037] - Extend the forbidden subchannel bitmap to include a bitmap potentially for at least 480 MHz.

[0038] - Extend the BSS bandwidth indication to 240 MHz and potentially to at least 480 MHz or 640 MHz.

[0039] - Extend the OM indication to include 240 MHz and potentially 480 MHz or 640 MHz.

[0040] - Extend the U-SIG indication to include 240 MHz and potentially 480 MHz or 640 MHz.

[0041] - Extend the puncturing pattern to 240 MHz and potentially to 480 MHz or 640 MHz.

[0042] - Extend the scrambler seed indication to include 240 MHz and potentially to include 480 MHz or 640 MHz.

[0043] - Extend the UL bandwidth indication in the trigger frame to include 240 MHz and potentially 480 MHz or 640 MHz.

[0044] 240MHz or 480MHz bandwidth will increase maximum speeds in Wi-Fi 8 by 50 percent compared to 160MHz in the 5GHz band and 320MHz in the 6GHz band.

[0045] The above description is for illustration only and is not meant to be limiting. There may be many other examples, configurations, processes, algorithms, etc., some of which will be described in more detail below.

For example, IoT devices may include, but are not limited to, refrigerators, toasters, ovens, microwave ovens, freezers, dishwashers, dishes, hand tools, washing machines, dryers, stoves, air conditioners, thermostats, televisions, lamps, vacuum cleaners, sprinklers, electric meters, gas meters, etc., as long as these devices are equipped with an addressable communication interface for communicating with the IoT network. IoT devices may also include cellular phones, desktop computers, laptop computers, tablet computers, personal digital assistants (PDAs), etc. Therefore, the IoT network includes a combination of "old-fashioned" Internet-accessible devices (e.g., laptop or desktop computers, cellular phones, etc.) in addition to devices that do not typically have Internet connectivity (such as dishwashers, etc.).

[0057] In one or more embodiments, the AP 102 and the user device 120 may exchange frames 140. The frames 140 may include bandwidth signaling 142 provided by the AP 102 to communicate to the user device 120 the bandwidth used for transmissions between the AP 102 and the user device 120. For example, the bandwidth signaling 142 may communicate 240 MHz in a 5 GHz bandwidth or 480 MHz in a 6 GHz bandwidth.

[0082] Figure 6 A format 600 of a trigger frame is depicted according to one or more example embodiments of the present disclosure.

[0083] In 802.11, a trigger frame can be sent by an AP (e.g. Figure 1 AP 102) to one or more station devices (e.g., Figure 1 The user equipment 120) triggers the station device to send uplink (UL) traffic to the AP.

[0084] refer to Figure 6 , the trigger frame may include a frame control field 602, a duration field 604, a receiver address (RA) field 606, a transmitter address (TA) field 608, common information 610 (e.g., information related to all devices receiving the trigger frame), user-specific fields (e.g., user information 612, ..., user information 614, which is specific to the STA addressed in the corresponding user-specific field), padding 616, and a frame control sequence (FCS) 618. Any user-specific field (e.g., user information 612) may include a special user information field 620, which does not carry user-specific information, but carries extended common information not provided in the common information 610 (e.g., for all receiving devices).

[0085] Still refer to Figure 6, the special user information field 620 may include AID12 (association identifier) ​​622, a PHY version identifier 624, a UL bandwidth extension (BE) 626, an EHT spatial reuse 1 field 628, an EHT spatial reuse 2 field 630, a U-SIG ignore and verify field 632, a UL bandwidth further extension field 634, a reserved field 636, and trigger-related user information 638 for the addressed user of AID12 622. The common information 610 may include a UL bandwidth (BW) subfield 640 for indicating the bandwidth to the receiving device.

[0086] The UL BE subfield 626, together with the UL BW subfield 640 in the common information 610, indicates the bandwidth of the requested TB PPDU from the addressed EHT STA (i.e., the bandwidth in the U-SIG field of the EHT TB PPDU). Two bits of the reserved field 636 may be used to create a UL bandwidth further extension field 634 for higher bandwidth signaling. An example of higher bandwidth signaling using a trigger frame is shown in Table 5 below.

[0088]

[0089] Figure 7 An example diagram of a process 700 for communicating high bandwidth for Wi-Fi communications is shown in accordance with one or more example embodiments of the present disclosure.

[0090] At block 702, a device (e.g., Figure 1 AP 102 Fig. 9 The enhanced signaling device 919 of the BSS may determine one or more STAs (eg, Figure 1 A channel used by user equipment 120) consisting of contiguous 240 MHz in the 5 GHz bandwidth or contiguous 480 MHz in the 6 GHz bandwidth. When using the 5 GHz bandwidth, there are currently no contiguous 240 MHz channels that can be allocated; the highest contiguous channel that can currently be allocated is 160 MHz. When using the 6 GHz bandwidth, there are currently no contiguous 480 MHz channels that can be allocated; the highest contiguous channel that can currently be allocated is 320 MHz. In the 6 GHz bandwidth, a 640 MHz channel allocation may exceed the regulatory limit of 500 MHz (at 500 MHz, power spectral density emission limitations may render the transmission invalid), but a 480 MHz transmission would circumvent this limitation if it could be passed.

[0091] At block 704, the device may generate a frame including an indication of a channel (e.g., an allocation of contiguous 240 MHz channels in a 5 GHz bandwidth or contiguous 480 MHz channels in a 6 GHz bandwidth may be communicated). The signaling may be as described above and may include the following changes to 802.11:

[0092] - Extend the forbidden subchannel bitmap to include a bitmap potentially for at least 480 MHz.

[0093] - Extend the BSS bandwidth indication to 240 MHz and potentially to at least 480 MHz or 640 MHz.

[0094] - Extend the OM indication to include 240 MHz and potentially 480 MHz or 640 MHz.

[0095] - Extend the U-SIG indication to include 240 MHz and potentially 480 MHz or 640 MHz.

[0096] - Extend the puncturing pattern to 240 MHz and potentially to 480 MHz or 640 MHz.

[0097] - Extend the scrambler seed indication to include 240 MHz and potentially to include 480 MHz or 640 MHz.

[0098] - Extend the UL bandwidth indication in the trigger frame to include 240 MHz and potentially 480 MHz or 640 MHz.

[0099] At block 706, the device may send the frame to a station device of the BSS, thereby establishing a channel for subsequent transmissions between the device and the station device.

In a networked deployment, the machine 900 can be operated in a server-client network environment with the capabilities of a server machine, a client machine, or both. In one example, the machine 900 can be a peer machine in a peer-to-peer (P2P) (or other distributed) network environment.

In addition, although only a single machine is shown, the term "machine" should also be deemed to include any machine collection (such as, cloud computing, software as a service (SaaS), other computer cluster configurations) that executes a set (or multiple sets) of instructions to execute any one or more methods discussed herein, either individually or jointly.

[0110] As described herein, examples may include logic or multiple components, modules, or mechanisms, or may be operated on them. A module is a tangible entity (e.g., hardware) that can perform a specified operation when in operation. A module includes hardware.

In another example, the hardware may include a configurable execution unit (e.g., a transistor, a circuit, etc.) and a computer-readable medium containing instructions, wherein the instructions configure the execution unit to perform a specific operation when in operation. Configuration may be performed under the guidance of the execution unit or a loading mechanism. Therefore, when the device is in operation, the execution unit is communicatively coupled to the computer-readable medium. In this example, the execution unit may be a member of more than one module. For example, in operation, the execution unit may be configured by a first set of instructions to implement a first module at a point in time, and reconfigured by a second set of instructions to implement a second module at a second point in time.

[0116] Various embodiments may be implemented in whole or in part in software and / or firmware. The software and / or firmware may take the form of instructions contained in or on a non-transitory computer-readable storage medium. These instructions may then be read and executed by one or more processors to enable the operations described herein to be performed.
