[0112] Return to reference Figure 1In some exemplary embodiments, devices 102 and / or 140 may be configured to generate, transmit, receive and / or process one or more transmissions, such as those comprising one or more EHT PPDUs, as described below.

[0113] In some exemplary embodiments, for example, devices 102 and / or 140 may be configured to perform one or more operations and / or functions of an EHT STA, such operations and / or functions may be configured to, for example, generate, transmit, receive, and / or process one or more transmissions, such as including one or more EHT PPDUs, which, for example, include according to Figure 2 One or more fields in EHTPPDU format.

[0114] In some exemplary embodiments, devices 102 and / or 140 may be configured to generate, transmit, receive, and / or process EHT PPDUs, for example, according to the IEEE 802.11be specification and / or any other specification, as described below.

[0116] In some exemplary aspects, an EHT MU PPDU may include a PPDU carrying one or more PHY Service Data Units (PSDUs) for one or more STAs using downlink multiple-user multiple-input multiple-output (DL-MU-MIMO) technology, orthogonal frequency division multiple access (DL OFDMA) technology, or a combination of both technologies.

[0117] In some exemplary embodiments, for example, devices 102 and / or 140 may be configured to perform one or more operations and / or functions of EHT STA, which may be configured to generate, transmit, receive and / or process EHT MU PPDUs, for example, on channel widths of 20 MHz, 40 MHz, 80 MHz, 160 MHz and / or 320 MHz.

[0118] In other embodiments, any other additional or alternative channel widths may be utilized.

[0119] In some exemplary embodiments, it may be necessary to address one or more technical aspects regarding the delivery of PPDUs (e.g., EHTPPDUs and / or any other PPDUs) over wide channel BW, for example, for use in next-generation Wi-Fi implementations, as described below.

[0120] For example, (for example, according to the IEEE 802.11-2020 specification) some technologies may be limited by a maximum bandwidth of 160MHz that can be used for transmission. For example, a first mode of 160MHz operation may include a continuous 160MHz mode, which can utilize a continuous 160MHz channel. For example, a second mode of 160MHz operation may include an 80MHz+80MHz mode, where each 80MHz segment is continuous, but the two 80MHz segments may not be continuous.

[0121] Some exemplary embodiments can be implemented to address the transmission of PPDUs (e.g., EHT PPDUs and / or any other PPDUs) over a channel width (e.g., a 320MHz channel width and / or any other wide channel width), as described below, for example.

[0122] Some exemplary embodiments can be implemented to address one or more technical problems concerning the delivery of PPDUs (e.g., EHT PPDUs and / or any other PPDUs) over a continuous 320MHz channel width and / or a 160+160MHz channel width, for example, based on a two-segment design with two 160MHz segments, as described below.

[0123] In some exemplary embodiments, an EHT STA (e.g., an EHT STA implemented by device 102 and / or an EHT STA implemented by device 140) may be configured to deliver one or more legacy PPDUs (e.g., non-HT PPDUs and / or non-HT duplicate PPDUs), for example to maintain coexistence with one or more legacy STAs (e.g., one or more non-EHT and / or non-HT STAs), as described below.

[0124] In some exemplary embodiments, an EHT STA (e.g., an EHT STA implemented by device 102 and / or an EHT STA implemented by device 140) may be configured to deliver one or more legacy PPDUs (e.g., non-HT PPDUs and / or non-HT duplicate PPDUs), for example, to preserve the radio medium, for example, to obtain a transmission opportunity (TXOP), for example, to be used for the transmission of one or more EHT PPDUs, as described below.

[0125] In some exemplary embodiments, an EHT STA (e.g., an EHT STA implemented by device 102 and / or an EHT STA implemented by device 140) can be configured to utilize EHT-enabled operation over a wide bandwidth (e.g., a channel width of 320 MHz).

[0126] In some exemplary embodiments, an EHT STA (e.g., an EHT STA implemented by device 102 and / or an EHT STA implemented by device 140) may be configured to utilize one or more fields in an EHT PPDU that may be configured to indicate the bandwidth of the PPDU transmission.

[0127] However, unlike EHT PPDUs (which may include one or more fields configured to indicate EHT bandwidth (e.g., a 320 MHz channel width or any other EHT bandwidth), legacy frame formats (e.g., non-HT PPDU formats) may not be configured to indicate EHT bandwidth.

[0128] In some exemplary embodiments, an EHT STA (e.g., an EHT STA implemented by device 102 and / or an EHT STA implemented by device 140) can be configured to utilize the transmission of one or more control frames according to a non-EHT format (e.g., a legacy format or a non-HT format), the non-HT format being recognizable, decodeable, and / or processed by one or more devices (“non-EHT devices” or “legacy devices”) that may not support one or more features and / or mechanisms (“non-legacy” mechanisms or “non-EHT mechanisms”). For example, legacy devices may include non-EHT stations and / or non-high-throughput (HT) stations, which may be configured, for example, according to the IEEE 802.11-2020 standard.

[0129] In one example, such as according to the IEEE 802.11-2020 standard, control frames may include, for example, Request to Send (RTS) frames, Clear to Send (CTS) frames, and / or any other type of control frame.

[0131] In some exemplary embodiments, EHT STA (e.g., EHT STA implemented by device 102 and / or EHT STA implemented by device 140) can be configured to transmit control frames (e.g., RTS, CTS and / or any other control frames) according to a non-HT PPDU format.

[0133] For example, before using a wide channel to send and / or receive PPDUs, it may be necessary to ensure that each 20MHz channel of the wide channel is idle, for example, in order to comply with the requirements of the channel bundling process used to utilize the wide channel.

[0134] For example, the sender and receiver can use control mechanisms to exchange control sequences to know what bandwidth is available during TxOP (e.g., maximum idle bandwidth). In one example, the control sequence may include RTS / CTS switching.

[0135] In some exemplary embodiments, an EHT STA (e.g., an EHT STA implemented by device 102 and / or an EHT STA implemented by device 140) may be configured to utilize one or more PPDU fields that may be configured to provide bandwidth information for a wide channel width (e.g., a 320 MHz channel width and / or any other channel width) in one or more PPDU formats (e.g., a non-HT PPDU format and / or a non-HT replicated PPDU format), as described below.

[0136] In some exemplary embodiments, the PPDU format (e.g., non-HT PPDU format and / or non-HT replicated PPDU format) can be configured to provide bandwidth information for wide channel bandwidth (BW), as described below.

[0137] In some exemplary embodiments, a PPDU format configured to provide bandwidth information for wide channel bandwidth (BW) can be used to provide the following technical solutions: supporting the transmission of control frames, for example as part of RTS / CTS exchanges and / or any other control frame exchanges, for example to derive the expected operating bandwidth, and / or dynamically converging to the highest bandwidth available to both the receiver and the sender, for example before transmission and / or reception.

[0138] In some exemplary embodiments, devices 102 and / or 140 may be configured to perform one or more operations and / or functions of EHT STA, such as generating, transmitting, receiving and / or processing PPDUs including an indication of a 320 MHz channel width.

[0212] Reference Figure 3 It schematically illustrates the service field bit assignment that can be implemented according to some exemplary embodiments.

[0213] In some exemplary embodiments, such as Figure 3 As shown, service field 300 can include multiple bits, such as 16 bits, represented as bits B0...B15 (or bits 0...15). For example, as... Figure 3 As shown, bit 0 can be sent first in time.

[0214] In some exemplary embodiments, service field 300 can be configured for PPDUs, for example, based on a non-HT PPDU format (e.g., a non-HT copy PPDU format).

[0215] In some exemplary embodiments, service field 300 may be included as part of the data field of the PPDU. For example, the data field may include service field 300, which may be followed by the PSDU.

[0216] In some exemplary embodiments, the bit assignment of service field 300 may be configured, for example, according to a non-HT PPDU format (e.g., a non-HT copied PPDU format), such as according to the IEEE 802.11-2020 specification.

[0217] In some exemplary embodiments, such as Figure 3 As shown, the bit assignment of service field 300 may include scrambler initialization sequence portion 302, which may be followed by reserved portion 304.

[0218] In some exemplary embodiments, such as Figure 3 As shown, the scrambler initialization sequence portion 302 may include 7 bits, such as bits B0, B1, B2, B3, B4, B5 and B6.

[0219] In some exemplary embodiments, such as Figure 3 As shown, the reserved portion 304 may include 9 bits, such as bits B7, B8, B9, B10, B11, B12, B13, B14 and B15.

[0220] In some exemplary embodiments, the bits of the scrambler initialization sequence portion 302 can be used to indicate, for example, the channel width in a control frame, as described below.

[0221] For example, the transmit address (TA) field of a control frame can be set to the bandwidth signaling TA by setting a single / group bit of the MAC address to 1. Any other additional or alternative mechanisms can be implemented to indicate the bandwidth signaling TA.

[0222] For example, if bandwidth signaling TA is sent in a PPDU, bits of the service field of the PPDU (e.g., bits that can typically be used for scrambling initialization, such as bits in part 302) can be reused for bandwidth signaling.

[0223] For example, when a bandwidth signaling TA is sent in a PPDU, the bits of the service field (e.g., service field 300) of the PPDU can be set to carry the bandwidth of the PPDU and / or one or more other indications (e.g., whether the device sending the PPDU supports static or dynamic bandwidth operation).

[0224] For example, when the TA field of the PPDU is set to bandwidth signaling TA, the bits of the scrambler initialization sequence portion 302 of the service field 300 can be used to provide a channel width indication.

[0225] For example, the bits of the scrambler initialization sequence portion 302 of the service field 300 can be used to indicate the CH_BANDWIDTH_IN_NON_HT parameter, which can be used to indicate the channel width of the PPDU, as described below.

[0226] In some exemplary embodiments, the 3 bits of the service field 300 can be used to indicate a channel width of 320 MHz, for example, as described below.

[0227] In some exemplary embodiments, the three bits of the service field 300 used to indicate a channel width of 320 MHz may include two bits of the scrambler initialization sequence portion 302 and one bit of the reserved portion 304, as described below, for example.

[0228] In some exemplary embodiments, the three bits of the service field 300 used to indicate a channel width of 320 MHz may include bits B5, B6, and B7 of the service field 300, as described below, for example.

[0229] In some exemplary embodiments, the 3 bits of the service field 300 may be used to indicate the CH_BANDWIDTH_IN_NON_HT parameter for a channel width of 320 MHz, as described below, for example.

[0230] In some exemplary embodiments, the three bits of the service field 300 for indicating the CH_BANDWIDTH_IN_NON_HT parameter for a channel width of 320 MHz may include two bits of the scrambler initialization sequence portion 302 and one bit of the reserved portion 304, as described below, for example.

[0231] In some exemplary embodiments, the three bits of the service field 300 used to indicate the CH_BANDWIDTH_IN_NON_HT parameter for a channel width of 320 MHz may include bits B5, B6, and B7 of the service field 300, as described below, for example.

[0232] In some exemplary embodiments, one of the reserved bits in the reserved portion 304 may be used, for example, together with two bits in the scrambler initialization sequence portion 302, to define the CH_BANDWDITH_IN_NON_HT field and / or the Channel-BW-in-non-HT-temp (CBWinNonHTtemp) field as a 3-bit field, for example, instead of a 2-bit field that only includes the bits of the scrambler initialization sequence portion 302.

[0233] In some exemplary embodiments, such as when a PPDU is to be sent to a Next Best Thing (NBT) STA, one reserved bit in the reserved portion 304 may be used, for example, along with two bits in the scrambler initialization sequence portion 302, to define the CH_BANDWDITH_IN_NON_HT field and / or the CBWinNonHTtemp field as a 3-bit field. For example, if the transmission is to be sent to a non-HT STA (e.g., an STA conforming to the IEEE 802.11ax standard), this new bit may not be modulated.

[0234] In some exemplary embodiments, for example, bit B7 of service field 300, together with two bits (e.g., bits B5 and B6) of scrambler initialization sequence portion 302, can be set to define the CH_BANDWDITH_IN_NON_HT field and / or the CBWinNonHTtemp field as 3-bit fields.

[0235] In some exemplary embodiments, another option may be to define the CH_BANDWDITH_IN_NON_HT field and / or the CBWinNonHTtemp field as 3-bit fields using three of the seven bits of the scrambler initialization sequence portion 302.

[0236] For example, in addition to bits B5 and B6, another of the seven bits in sequence portion 302 can be initialized using a scrambler. Depending on this option, the number of bits used to generate the pseudo-random integer can be reduced from four bits to three.

[0237] In one example, one of bits B0-B4 (e.g., bit B3 or any other bit), along with bits B5 and B6, can be used to define the CH_BANDWDITH_IN_NON_HT field and / or the CBWinNonHTtemp field, for example, to signal a 320MHz channel width. According to this example, the remaining bits of B0-B4 (e.g., bits B0, B1, B2, and / or B4) can be used to generate pseudo-random integers.

[0238] In some exemplary embodiments, additional bits (e.g., bit B7 in reserved portion 304) or additional bits (e.g., bit B3) in scrambler initialization sequence portion 302 may be used to indicate one or more modes or combinations for a 320MHz channel width, such as continuous or non-continuous formats.

[0239] In some exemplary embodiments, additional bits (e.g., bit B7 in reserved portion 304) or additional bits (e.g., bit B3) in scrambler initialization sequence portion 302 may be set to predefined values ​​(e.g., 1), and two bits (e.g., bits B5 and B6) in scrambler initialization sequence portion 302 may be set to predetermined values ​​(e.g., 3) to define a new 320MHz channel width pattern.

[0240] In some exemplary embodiments, for example, the dot11currentchannelcenterfrequencyindex1 parameter can be set to a first value (e.g., 0) for continuous operation over a continuous 320MHz channel width.

[0241] In some exemplary embodiments, for example, the dotllcurrentchannelcenterfrequencyindexl parameter can be set to a second value (e.g., other than 0) for non-contiguous 160+160MHz channel widths.

[0242] For example, if an additional bit (e.g., bit B7 in reserved portion 304) or an additional bit (e.g., bit B3) in scrambler initialization sequence portion 302 is set to 0, the signaling scheme can conform to a signaling scheme for 160MHz.

[0243] In some exemplary embodiments, in another option, the 3-bit CH_BANDWDITH_IN_NON_HT field and / or the 3-bit CBWinNonHTtemp field can be defined, for example, based on the values ​​of the three bits in service field 300, as a new 3-bit field with eight combinations. The three bits in service field 300 may include two bits (e.g., bits B5 and B6) and an additional bit (e.g., bit B7 in reserved portion 304) in scrambler initialization sequence portion 302, or an additional bit (e.g., bit B3) in scrambler initialization sequence portion 302, as described above.

[0244] In one example, a 3-bit value of 0 can be assigned to indicate a 20MHz channel width, a 3-bit value of 1 can be assigned to indicate a 40MHz channel width, a 3-bit value of 2 can be assigned to indicate an 80MHz channel width, a 3-bit value of 3 can be assigned to indicate a 160MHz channel width, and / or a 3-bit value of 4 can be assigned to indicate a 320MHz channel width.

[0245] For example, the 3-bit CH_BANDWDITH_IN_NON_HT field and / or the 3-bit CBWinNonHTtemp field can be defined as follows:

[0246]

[0247] Table 1

[0248] In some exemplary embodiments, other 3-bit values ​​(e.g., 5, 6, and / or 7) may be used to indicate further extension, such as extension to a 640 MHz channel width.

[0249] Return to reference Figure 1 In some exemplary embodiments, devices 102 and / or 140 may be configured to generate, process, transmit, and / or receive PPDUs, the PPDUs including an indication of whether the service field of the PPDU will be interpreted as including a 3-bit indication of the channel width, as described below, for example.

[0250] In some exemplary embodiments, it can be useful for the receiver supporting the PPDU to determine whether the service field of the PPDU should be interpreted as including a 3-bit indication of the channel width in order to determine how to process the bits of the service field. For example, the receiver can be indicated whether the bits of the service field are processed according to the 3-bit channel width indication, as described above, or according to the 2-bit channel width indication.

[0251] In some exemplary embodiments, the TA field carrying the sender's MAC address in the control frame can be configured as a bandwidth signaling TA, for example by modifying the MAC address by setting the individual / group bits to 1 (e.g., instead of 0), as described above.

[0252] In some exemplary embodiments, another part of the MAC address may be changed, for example from 0 to 1, to signal that the TA field will be identified as “EHT Bandwidth Signaling TA”. For example, when the TA field is identified as EHT Bandwidth Signaling TA, the service field is encoded and processed to include the mechanism described above for signaling that allows 320MHz bandwidth (e.g., using a 3-bit value).

[0253] In some exemplary embodiments, another option may be to use reserved fields in the MAC header of the corresponding frame.

[0254] Reference Figure 4 It schematically illustrates the subfield values ​​of the frame control field, which can be implemented according to some exemplary embodiments.

[0255] For example, Figure 4 One of the fields in the frame control field can be set to "1" and used as a non-reserved field. For example, at least one of the fields "To DS", "From DS", "More Flags", "Retry", "Protected Frame" and / or "+HTC" can be set to the value "1" to indicate that the service field is encoded as and to be processed to include the signaling (e.g., using a 3-bit value) described above for allowing 320MHz bandwidth.

[0256] In some exemplary embodiments, the Receiver Address (RA) field of the PPDU can be configured to provide an indication of whether the service field of the PPDU should be interpreted as including a 3-bit indication of the channel width. For example, to indicate EHT resolution of the service field of the PPDU, the sender of the PPDU (e.g., by device 102) Figure 1 The implemented STA can include bandwidth signaling TA in the TA field of the PPDU and bandwidth signaling RA in the RA field of the PPDU. For example, bandwidth signaling RA can be identified when the unicast / multicast bit in the MAC address of the RA field is set to multicast (e.g., instead of unicast). Any other settings in the RA field can be used to indicate EHT bandwidth signaling RA.

[0257] Return to reference Figure 1 In some exemplary embodiments, devices 102 and / or 140 may be configured, for example, based on a service field (e.g., service field 300). Figure 3The two bits in the )) generate, process, send and / or receive PPDUs including an indication of the 320MHz field, as described below.

[0258] In some exemplary embodiments, when the PPDU is sent to an EHT STA (e.g., an NBT STA), the 2-digit field format can be redefined (e.g., using the service field 300). Figure 3 (bits B5 and B6). For example, a 2-bit value entry can be offset from (0 for 20MHz, 1 for 40MHz, 2 for 80MHz, 3 for 160MHz) to (0 for 40MHz, 1 for 80MHz, 2 for 160MHz, 3 for 320MHz). For example, the first set of entries (0 for 20MHz, 1 for 40MHz, 2 for 80MHz, 3 for 160MHz) can be used to interpret PPDUs sent to non-EHT STAs, while the second set of entries (0 for 40MHz, 1 for 80MHz, 2 for 160MHz, 3 for 320MHz) can be used to interpret PPDUs sent to EHT STAs.

[0259] In some exemplary embodiments, another option for signaling the 320MHz bandwidth could be to define new control frame formats, such as new RTS frames, new CTS frames, and / or any other new control frames indicating channel width, for communication over the 6GHz band. For example, new fields could be used to indicate the bandwidth in these new frames. This field could be 3 bits or more (if more non-contiguous combinations are needed).

[0260] In one example, a CTS frame can be configured to include both the TA field and the Receiver Address (RA) field. This configuration could be beneficial, for example, if it is decided that all STAs under 6 GHz (including legacy STAs as .11ax STAs) should use the new CTS and RTS formats (e.g., instead of the old RTS and CTS formats).

[0261] Reference Figure 5 This schematically illustrates a method for transmitting a PPDU with an indication of a 320MHz channel width according to some exemplary embodiments. For example, Figure 5 One or more operations of the method can be performed by the system (e.g., system 100).

[0262] As shown in box 502, the method may include: setting three bits in the service field of the PPDU to a predefined bit setting configured to indicate a channel width of 320 MHz. For example, controller 124 ( Figure 1 ) can be configured to: cause, trigger, and / or control device 102 ( Figure 1 Set three bits in the service field of the PPDU to a predefined bit setting that is configured to indicate a channel width of 320 MHz, for example, as described above.

[0266] As shown in box 604, the method may include, for example, determining that the channel width of the PPDU is a 320MHz channel width based on a predefined bit setting in the determination service field having three bits configured to indicate a channel width of 320MHz. For example, controller 154 ( Figure 1 ) can be configured to: cause, trigger, and / or control device 140 ( Figure 1 For example, based on a predefined bit setting in the determination service field having three bits configured to indicate a channel width of 320 MHz, the channel width of the PPDU is determined to be a channel width of 320 MHz, as described above.
