[0024] User equipment 120 and / or AP 102 may also include, for example, mesh stations in a mesh network in accordance with one or more IEEE 802.11 standards and / or 3GPP standards.
[0025] Any of the user devices 120 (e.g., user devices 124, 126, 128) and AP 102 may be configured to communicate with each other in a wireless or wired manner via one or more communication networks 130 and / or 135. The user devices 120 may also communicate with each other peer-to-peer or directly with or without AP 102. Any of the communication networks 130 and / or 135 may include, but are not limited to, any combination of suitable communication networks of different types, such as broadcast networks, wired networks, public networks (e.g., the Internet), private networks, wireless networks, cellular networks, or any other suitable private and / or public networks.

[0026] Any of the user devices 120 (e.g., user devices 124, 126, 128) and the AP 102 may include one or more communication antennas. The one or more communication antennas may be any suitable type of antenna corresponding to the communication protocol used by the user devices 120 (e.g., user devices 124, 126, and 128) and the AP 102. Some non-limiting examples of suitable communication antennas include Wi-Fi antennas, Institute of Electrical and Electronics Engineers (IEEE) 802.11 series standard compliant antennas, directional antennas, non-directional antennas, dipole antennas, folded dipole antennas, patch antennas, multiple-input multiple-output (MIMO) antennas, omnidirectional antennas, quasi-omnidirectional antennas, etc. The one or more communication antennas may be communicatively coupled to a radio component to send and / or receive signals, such as communication signals, to and / or from the user devices 120 and / or the AP 102.

Any one of the user equipment 120 (e.g., user equipment 124, 126, 128) and AP 102 can be configured to use a set of multiple antenna arrays (e.g., DMG antenna arrays, etc.) to perform such directional transmission and / or reception. Each of the multiple antenna arrays can be used for transmission and / or reception in a specific corresponding direction or range of directions. Any one of the user equipment 120 (e.g., user equipment 124, 126, 128) and AP 102 can be configured to perform any given directional transmission to one or more defined transmission sectors. Any one of the user equipment 120 (e.g., user equipment 124, 126, 128) and AP 102 can be configured to perform any given directional reception from one or more defined reception sectors.
[0028] MIMO beamforming in wireless networks can be implemented using RF beamforming and / or digital beamforming. In some embodiments, in performing a given MIMO transmission, user equipment 120 and / or AP 102 can be configured to perform MIMO beamforming using all or a subset of its one or more communication antennas.
[0029] Any of the user devices 120 (e.g., user devices 124, 126, 128) and AP 102 may include any suitable radio and / or transceiver for sending and / or receiving radio frequency (RF) signals in a bandwidth and / or channel corresponding to a communication protocol used by any of the user devices 120 and AP 102 to communicate with each other.

The radio component may also have hardware and / or software instructions to communicate via one or more Wi-Fi and / or Wi-Fi Direct protocols, as standardized by the Institute of Electrical and Electronics Engineers (IEEE) 802.11 standards. In certain example embodiments, a radio component cooperating with a communication antenna may be configured to communicate via a 2.4 GHz channel (e.g., 802.11b, 802.11g, 802.11n, 802.11ax), a 5 GHz channel (e.g., 802.11n, 802.11ac, 802.11ax), or a 60 GHZ channel (e.g., 802.11ad, 802.11ay), an 800 MHz channel (e.g., 802.11ah). The communication antenna may operate at 28 GHz and 40 GHz. It should be understood that the list of communication channels according to certain 802.11 standards is only a partial list, and other 802.11 standards (e.g., next generation Wi-Fi or other standards) may be used. In some embodiments, non-Wi-Fi protocols may be used for communication between devices, such as Bluetooth, dedicated short range communication (DSRC), ultra-high frequency (UHF) (e.g., IEEE 802.11af, IEEE 802.22), white band frequencies (e.g., white space), or other packet radio communications. The radio assembly may include any known receiver and baseband suitable for communicating via a communication protocol. The radio assembly may also include a low noise amplifier (LNA), additional signal amplifiers, an analog-to-digital (A / D) converter, one or more buffers, and a digital baseband.
[0030] In one embodiment, referring to Figure 1, the user equipment 120 may communicate with one or more APs 102. For example, one or more APs 102 may implement an enhanced sensing trigger frame 142 with one or more user equipment 120. Each of the one or more APs 102 may include multiple individual APs (e.g., AP1, AP2, ... APn, where n is an integer), and each of the one or more user equipment 120 may include multiple individual STAs (e.g., STA1, STA2, ..., STAn). (One or more) APs and (one or more) STAs may establish one or more links (e.g., link 1, link 2, ..., link n) between each individual AP and STA. It should be understood that the above description is for illustrative purposes and is not meant to be limiting.
[0031] IEEE 802.11bf (e.g., IEEE 802.11bf D1.1, May 2023) is a standard that aims to standardize Wi-Fi sensing, which uses Wi-Fi technology to perform radar-like applications, such as detecting motion in a room or detecting when a person approaches a target device. Sensing is achieved by tracking channel estimates obtained when decoding multiple Wi-Fi packets over time and detecting changes that indicate events of interest.
[0032] Regarding the specific measurement process, IEEE 802.11bf adopts the measurement process based on trigger (TB) and non-trigger based (NTB). For the TB sensing measurement instance, different variants of the sensing trigger frame (Sensing Trigger frame) are used to perform the corresponding functions, including the sensing polling trigger frame (Sensing Polling Trigger frame), the sensing responder to the sensing initiator (Sensing Responder to Sensing Initiator, SR2SI) sounding trigger frame (SR2SI Sounding Trigger frame), the sensing threshold-based reporting trigger frame (Sensing Threshold-basedReporting Trigger frame), the sensing reporting trigger frame (Sensing Reporting Trigger frame), the sensing responder to the sensing responder (Sensing Responder to Sensing Responder, SR2SR) sounding trigger frame (SR2SR Sounding Trigger frame), etc. In addition, the sensing trigger frame can reuse the ranging trigger frame (Ranging Trigger frame) defined in IEEE 802.11az.
[0033] However, existing variants of sensing trigger frames have some limitations. For example, they only support bandwidths up to 160 MHz, and the response to these trigger frames can only be a high-efficiency (HE) TB physical layer (PHY) protocol data unit (PPDU) or HE PPDU.
[0034] Since IEEE 802.11bf agrees to support 320 MHz sensing, and IEEE 802.11bk will extend the ranging trigger frame to enable 320 MHz support, the IEEE 802.11bf sensing trigger frame also needs to be modified to support 320 MHz sensing.
[0035] Example embodiments of the present disclosure relate to systems, methods, and devices for designing a 320 MHz sensing trigger frame (including all applicable variations) for a Wi-Fi system (e.g., an IEEE 802.11bf system) to enable the sensing trigger frame of the Wi-Fi system (e.g., an IEEE 802.11bf system) to achieve 320 MHz support.
[0036] Figure 2 A flow chart of a method 200 for a 320 MHz sensing trigger frame according to some embodiments of the present disclosure is shown.
[0037] In some embodiments, the method 200 may be performed by an AP STA. In some embodiments, the method 200 may be performed by other STAs. The present disclosure is not limited in this respect.
[0038] In some embodiments, Figure 2 As shown, method 200 may include operations 210 and 220 .
[0039] At 210, the trigger frame is encoded for transmission to the responding STA. In some embodiments, the responding STA may be a non-AP STA. However, in some embodiments, the responding STA may include other (one or more) devices, which is not limited in the present disclosure.
[0040] A TB PPDU in response to the trigger frame is decoded at 220. The TB PPDU is received from a responding STA over a 320 MHz frequency band.
[0041] In some embodiments, the trigger frame may include a sensing polling trigger frame, a sensing threshold-based reporting trigger frame, a sensing report trigger frame, an SR2SI detection trigger frame, an SR2SR detection trigger frame, and the like.
[0042] In some embodiments, the TB PPDU may include a HE TB PPDU, an extremely high throughput (EHT) TB PPDU, a TB ranging Null Data Packet (NDP), a ranging NDP, and the like.
[0043] In some embodiments, by setting the corresponding user information field to HE variant or EHT variant, some sensing trigger frame variants (e.g., sensing polling trigger frame, sensing threshold-based reporting trigger frame, sensing report trigger frame, etc.) are allowed to request HE TB PPDU or EHT TB PPDU from (one or more) STAs accordingly.
[0044] In some embodiments, for responses to the 320 MHz SR2SI sounding trigger frame and the 320 MHz SR2SR sounding trigger frame, the requested PPDU type may be defined as 320 MHz TB ranging NDP and 320 MHz ranging NDP, respectively, such as defined in IEEE 802.11bk.
[0045] In some embodiments, the trigger frame may include a common information field and a user information field immediately following the common information field, and the value of the AID12 subfield of the user information field may be 2007 (AID12=2007), for example, as defined in IEEE802.11be (e.g., IEEE 802.11be D3.0, January 2023; IEEE 802.11be D3.2, May 2023).
[0046] In some embodiments, the uplink (UL) bandwidth (BW) subfield of the common information field and the UL bandwidth extension subfield of the user information field may jointly indicate that the bandwidth of the TB PPDU is 320 MHz or the trigger frame is a 320 MHz trigger frame. For example, Table 1 below shows an example of such an indication.
[0047] Table 1
[0048]
[0049] As can be seen from the example in Table 1, HE TB PPDU can only reach up to 160 MHz, while EHT TB PPDU can reach up to 320 MHz. However, in another example, both HE TB PPDU and EHT TB PPDU can reach 320 MHz; or in another example, EHT TB PPDU can only reach 160 MHz, but HE TB PPDU can reach 320 MHz. The present disclosure is not limited in this respect.
[0050] In some embodiments, if the user information field is an EHT variant and the TB PPDU includes an EHT TB PPDU, the user information field includes a UL modulation and coding scheme (MCS) subfield that is the same as the UL EHT MCS subfield in the EHT variant user information field.
[0051] In some embodiments, if the user information field is a HE variant and the TB PPDU includes a HE TB PPDU, the user information field includes a UL MCS subfield that is the same as the UL HE MCS subfield in the HE variant user information field.
[0052] In some embodiments, if the user information field is an EHT variant and the TB PPDU includes an EHT TB PPDU, the user information field includes a PS160 subfield, a resource unit (RU) allocation subfield, or a spatial stream (SS) allocation / random access (RA)-RU information subfield, which are respectively the same as corresponding subfields in an EHT variant user information field (e.g., an EHT variant user information field defined in 9.3.1.22.5 of IEEE 802.11be D3.0).
[0053] In some embodiments, if the User Information field is a HE variant and the TB PPDU includes a HE TB PPDU, bit B39 of the User Information field is reserved.
[0054] In some embodiments, if the user information field is an EHT variant and the TB PPDU includes an EHT TB PPDU, the user information field does not include a UL dual carrier modulation (DCM) subfield.
[0055] In some embodiments, if the user information field is a HE variant and the TB PPDU includes a HE TB PPDU, the RU allocation subfield, the UL DCM subfield, or the SS allocation / RA-RU information subfield of the user information field is the same as the corresponding subfield of the HE variant user information field (e.g., the HE variant user information field defined in 9.3.1.22.4 of IEEE 802.11be D3.0).
[0056] In some embodiments, according to the rules defined in IEEE 802.11be (e.g., Table 9-45c in IEEE 802.11be D3.0), based on whether the corresponding user information field is an EHT variant or a HE variant, a sensing polling trigger frame, a sensing threshold-based reporting trigger frame, or a sensing report trigger frame may be allowed to request an HE TB PPDU or an EHT TB PPDU from a STA. Additionally or alternatively, if the sensing polling trigger frame, the sensing threshold-based reporting trigger frame, or the sensing report trigger frame is requesting an HE TB PPDU, the following (one or more) rules must be met: i) the RU allocation, UL DCM, and SS allocation / RA-RU information subfields are the same as the corresponding subfields in the HE variant user information field (e.g., the HE variant user information field defined in 9.3.1.22.4 of IEEE 802.11be D3.0); ii) the UL MCS subfield is the same as the UL HE MCS subfield in the HE variant user information field; and / or iii) the PS160 subfield is reserved. If a sensing polling trigger frame, a sensing threshold-based reporting trigger frame, or a sensing report trigger frame is requesting an EHT TB PPDU, the following (one or more) rules must be met: i) the RU allocation, SS allocation / RA-RU information, and PS160 subfields are the same as the corresponding subfields in the EHT variant user information field (e.g., the EHT variant user information field defined in 9.3.1.22.5 of IEEE802.11be D3.0); ii) the UL MCS subfield is the same as the UL EHT MCS subfield in the EHT variant user information field; and / or iii) the UL DCM subfield is reserved.
[0057] Figure 3 An example of changing the user information field of a sensing polling trigger frame according to some embodiments of the present disclosure is shown. Figure 4 An example of changes to the user information field of a sensing report trigger frame and a sensing threshold-based report trigger frame according to some embodiments of the present disclosure is shown. Figure 3 and Figure 4 As shown, the "UL HE-MCS" subfield in the user information field of the sensing polling trigger frame, the sensing report trigger frame, and the sensing threshold-based report trigger frame is changed to "UL MCS". In addition, the bit B39 of the user information field in the sensing polling trigger frame, the sensing report trigger frame, and the sensing threshold-based report trigger frame is changed from "reserved" to "PS160".
[0058] In some embodiments, the SR2SI sounding trigger frame and the SR2SR sounding trigger frame may be enhanced (eg, extended) to support 320 MHz and define the requested PPDU type.
[0059] In some embodiments, for responses to a 320 MHz SR2SI sounding trigger frame and a 320 MHz SR2SR sounding trigger frame, the requested PPDU type may be defined as a 320 MHz TB ranging NDP and a 320 MHz ranging NDP, respectively, for example, as defined in IEEE 802.11bk.
[0060] In some embodiments, some subfields or indications may be reused for 320 MHz support for EHT trigger frames defined in IEEE 802.11be as signaling for 320 MHz support for sensing trigger frames.
[0061] In some embodiments, the reused subfield or indication may include a special user information field with AID12=2007.
[0062] In some embodiments, the reused subfield or indication may include bit B54 of the EHT variant common information field. Bit B54 is the HE / EHT P160 subfield in the EHT variant common information field. It is reserved in the HE variant common information field. For example, when the HE / EHT P160 subfield of the EHT variant common information field is set to, for example, 0, it may indicate that the requested TB PPDU in the main 160 MHz is an EHT TB PPDU. When the HE / EHT P160 subfield of the EHT variant common information field is set to, for example, 1, it may indicate that the requested TB PPDU in the main 160 MHz is an HE TB PPDU. In another example, another value of the HE / EHT P160 subfield may be used to indicate the TB PPDU type. The present disclosure is not limited in this regard.
[0063] In some embodiments, the reused subfield or indication may include bit B55 of the EHT variant common information field. It may be a special user information field flag subfield in the EHT variant common information field. Bit B55 may be reserved in the HE variant common information field.
[0064] In some embodiments, the reused subfield or indication may include bit B39 of the EHT Variant User Information field. If a HE TB PPDU is to be requested, bit B39 may be reserved, and if an EHT TB PPDU is to be requested, bit B39 may carry PS160.
[0065] Figure 5 A flow chart of a method 500 for a 320 MHz sensing trigger frame according to some embodiments of the present disclosure is shown.
[0066] In some embodiments, the method 500 may be performed by a non-AP STA. In some embodiments, the method 500 may be performed by other STAs. The present disclosure is not limited in this respect.
[0067] In some embodiments, Figure 5 As shown, method 500 may include operations 510 and 520 .
[0068] At 510, a trigger frame received from an initiating STA is decoded. In some embodiments, the initiating STA may be an AP STA. However, in some embodiments, the initiating STA may include (one or more) other devices, which is not limited in the present disclosure.
[0069] At 520, in response to the trigger frame, a TB PPDU is encoded for transmission to the initiating STA over the 320 MHz frequency band.
[0070] The method 500 can be understood in conjunction with the description of the above embodiments, and will not be described in detail here.
[0071] It is understandable that the technical solution of the present disclosure is not only applicable to the IEEE 802.11bf system, but also applicable to other IEEE 802.11 systems, such as the IEEE 802.11ax system, the IEEE 802.11be system, the IEEE 802.11bf system, etc. The present disclosure is not limited in this respect.
[0072] Using the technical solutions of the present disclosure, the sensing trigger frame (including all applicable variants) can be enhanced (e.g., extended) to support 320MHz. For example, an enhanced sensing trigger frame can be sent in a 320MHz PPDU, and / or the enhanced sensing trigger frame can request a 320MHz TB PPDU (e.g., EHT TB PPDU) transmitted over a 320MHz bandwidth. The proposed scheme can implement broadcast sensing measurements of an IEEE 802.11bf system. For example, these schemes enable 320MHz support by, for example, reusing existing signaling defined for a basic trigger frame in IEEE 802.11be. In addition, these schemes also unify 320MHz sensing NDPs into ranging NDPs or TB ranging NDPs, which is consistent with the use of ranging NDPs and TB ranging NDPs agreed in IEEE 802.11bf in scenarios up to 160MHz.

[0112] According to one embodiment, mixer circuit 1002 may include: quadrature passive mixers (eg, for in-phase (I) and quadrature-phase (Q) paths). In such an embodiment, Fig.10 The RF input signal 907 may be downconverted to provide I and Q baseband output signals to be sent to a baseband processor.
[0113] The quadrature passive mixers may be driven by zero and ninety degree time varying LO switching signals provided by a quadrature circuit, which may be configured to receive an LO frequency (fLO) from a local oscillator or synthesizer, such as LO frequency 1005 (fLO) of synthesizer 1004. Fig.10 ). In some embodiments, the LO frequency may be the carrier frequency, while in other embodiments, the LO frequency may be a fraction of the carrier frequency (e.g., one-half of the carrier frequency, one-third of the carrier frequency). In some embodiments, the zero-degree and ninety-degree time-varying switching signals may be generated by a synthesizer, but the scope of the embodiments is not limited in this respect.
[0114] In some embodiments, the LO signal can differ in duty cycle (the percentage of a cycle that the LO signal is high) and / or offset (the difference between the start points of the cycle). In some embodiments, the LO signal can have an 85% duty cycle and an 80% offset. In some embodiments, each branch of the mixer circuit (e.g., the in-phase (I) and quadrature-phase (Q) paths) can operate at an 80% duty cycle, which can result in a significant reduction in power consumption.

According to some embodiments, the synthesizer circuit 1004 may include a digital synthesizer circuit. One advantage of using a digital synthesizer circuit is that, although it may still contain some analog components, its footprint may be much smaller than that of an analog synthesizer circuit. In some embodiments, the frequency input to the synthesizer circuit 1004 may be provided by a voltage controlled oscillator (VCO), although this is not required. Depending on the desired output frequency 1005, the divider control input may be further controlled by the baseband processing circuits 808a-b ( Figure 8 ) is provided. In some embodiments, the divider control input (e.g., N) can be determined from a lookup table (e.g., within a Wi-Fi card) based on the channel number and channel center frequency determined or indicated by the example application processor 810. The application processor 810 can include or otherwise be connected to one of the example secure signal converter 101 or the example receive signal converter 103 (e.g., depending on which device the example radio architecture is implemented in).
[0119] In some embodiments, the synthesizer circuit 1004 can be configured to generate a carrier frequency as the output frequency 1005, while in other embodiments, the output frequency 1005 can be a fraction of the carrier frequency (e.g., one-half of the carrier frequency, one-third of the carrier frequency). In some embodiments, the output frequency 1005 can be the LO frequency (fLO).

The baseband processing circuit 808a may also include control logic 1106 for coordinating the operation of the baseband processing circuit 808a.
