Description

Technical Field

[0001] This application relates to the field of communications, and more specifically, to an ELR PPDU indicating method, apparatus, and device. Background Technology

[0002] In indoor and outdoor IoT applications such as wireless video doorbells, outdoor surveillance cameras, wireless garage door controllers, outdoor sprinkler controllers, wireless speakers, smart appliances, and security IoT devices, there is a need for Wi-Fi (Wireless Fidelity) solutions that offer longer range, higher efficiency, and greater compatibility.

[0003] In current Wi-Fi products, because Access Points (APs) typically have higher transmission power than non-AP Stations (STAs), APs may experience transmission limitations, meaning there is an asymmetry in uplink and downlink coverage. For example, many people have experienced this: even when the Wi-Fi signal strength is only one or two bars, a non-AP STA cannot communicate with the AP. To address this issue, the industry uses ELR (Enhanced / Extended Long Range) PPDU (Presentation Protocol Data Unit) to remotely enhance data communication for terminal devices. However, if the terminal device is configured to always use ELR PPDU, it may lead to a waste of resources. For example, when the terminal device moves from a remote location to a location closer to the site device, it can meet the communication requirements without enabling ELR PPDU. If the terminal device is configured not to use ELR PPDU, then the problem of limited long-distance communication will occur. For example, when the terminal device moves from a location closer to the site device to a remote location and exceeds a certain range, the communication signal will be poor. Therefore, the current technology adapts to the changing needs of the terminal device. Summary of the Invention

[0032] The technical solutions of the embodiments of this application will now be described with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. All other embodiments obtained by those skilled in the art without creative effort regarding the embodiments of this application are within the scope of protection of this application.

[0033] It should be noted that, in this document, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Furthermore, the terms "first" and "second," etc., used herein are used only to distinguish different objects and not to describe a particular order.

[0034] It should be noted that, in the embodiments of this application, "at least one item" refers to one item or more items, "more items" refers to two items or more, and "at least two items" refers to two items or more. "At least one of the following items" or similar expressions can refer to any combination of these items. For example, at least one item of a, b, or c can mean: a, b, c, "a and b", "a and c", "b and c", or "a and b and c".

[0035] It should be noted that in the embodiments of this application, "and / or" indicates that the connected objects can have three relationships. For example, "A and / or B" can represent three scenarios: only A exists, only B exists, and both A and B exist simultaneously. The character " / " generally indicates that the preceding and following objects have an "or" relationship.

[0036] It should be understood that the "instruction" mentioned in the embodiments of this application can be a direct instruction or an indirect instruction. For example, A instructing B can mean that A directly instructs B, such as B being obtainable through A; or it can mean that A indirectly instructs B, such as A instructing C, where B is obtainable through C, for example, B and C are related.

[0037] The technical solutions provided in this application can be applied to wireless local area network (WLAN) systems, such as WiFi protocols. These WiFi protocols may include, but are not limited to, the 802.11 series protocols, such as 802.11a, 802.11ax, 802.11ac, 802.11b, 802.11be, 802.11g, 802.11n, 802.11bn, or next-generation protocols.

[0038] Figure 1 A schematic structural diagram of a communication system 100 applicable to embodiments of this application is shown. The communication system 100 may include an access point (AP) 110 and a station (Non-AP STA) 120. The station STA 120 can access the network through the access point 110.

[0039] Access points can support communication or sensing based on WiFi protocols, such as 802.11a, 802.11ax, 802.11ac, 802.11b, 802.11be, 802.11g, 802.11n, 802.11bn, or next-generation protocols.

[0040] The site can support communication or sensing based on WiFi protocols, such as 802.11a, 802.11ax, 802.11ac, 802.11b, 802.11be, 802.11g, 802.11n, 802.11bn, or next-generation protocols.

[0041] The communication in the communication system 100 can be communication between access points and stations, or communication between stations, or communication between access points.

[0042] An access point acts as a bridge connecting wired and wireless networks. Its main function is to connect various wireless network clients together and then connect the wireless network to the Ethernet.

[0043] Terminal equipment is also called a non-access point site (Non-AP STA), and site equipment is also called an access point or access point site (AP). In a sense, an access point is also a type of site.

[0044] In some scenarios, access points and sites can be devices used in the Internet of Vehicles (IoV), IoT nodes and sensors in the Internet of Things (IoT), smart cameras, smart remote controls, smart water and electricity meters in smart homes, and sensors in smart cities.

[0045] In some scenarios, the access point can be a terminal device (such as a mobile phone) with a WiFi chip or a network device (such as a router).

[0046] In this application embodiment, the site can be a mobile phone, tablet computer, computer, virtual reality (VR) device, augmented reality (AR) device, wireless device in industrial control, set-top box, wireless device in self-driving, vehicle communication device, wireless device in remote medical care, wireless device in smart grid, wireless device in transportation safety, wireless device in smart city or smart home, wireless device, wireless communication chip, etc. that support WLAN or WiFi technology.

[0047] It should be understood that Figure 1 Only one access point and two sites are shown in the example. Optionally, the communication system 100 may include multiple access points or other numbers of sites. This application embodiment does not limit this.

[0048] Optionally, the communication system 100 may also include other devices, such as network controllers, gateways, and other network entities, which are not limited in this application.

[0049] To facilitate understanding of the embodiments of this application, the related technologies are described.

[0050] Currently, devices supporting the Wi-Fi 5 (802.11ac) standard have service ranges limited by the uplink (UL). The current solution uses 11b technology in the 2.4GHz UL, resulting in approximately a 6dB improvement in UL. However, 11b technology was published in 1999, making it outdated and incompatible with channel coding, resulting in poor performance, poor forward compatibility, and difficulty in management. Therefore, a new generation of long-range solutions is needed that incorporate channel coding, OFDM / OFDMA, and MAC functionality to achieve longer communication distances and higher data rates. For devices that support the WIFI6 (802.11ax) standard, UORA (UL-OFDMA Random Access) is used to achieve a power gain of about 10 dBde. However, its use is limited in channels with limited DFS (Dynamic Frequency Selection) and PSD (Power Spectral Density). Furthermore, UORA is not widely used in products on the market (it is rarely seen in products) due to its low time efficiency (delay caused by transmission failures due to collisions). For devices supporting Wi-Fi 7 (802.11be), the ETH UL TB PPDU (EtherNet UPLine Trigger-Based Presentation Protocol Data Unit) in a small RU (Resource Unit) allows the STA to achieve longer-distance transmission by concentrating its power in a narrow bandwidth. However, since the UL TB PPDU lacks preamble processing, only processing EHT-STF, EHT-LTF, and the data portion, and the UL TB PPDU preamble is at least 20MHz, the AP cannot receive it over such a long distance. For future devices supporting the Wi-Fi 8 (802.11bn) standard, to address the link budget imbalance caused by the difference in uplink and downlink transmit power, it is necessary to define ELR PPDU to improve the STA's uplink range (including uplink association request, sounding feedback, BA / ACK, UL ​​SUdata) and enhance the coexistence and throughput of 2.4GHz uplink and downlink. The design goal of the ELR PPDU is to improve the 1Mbps range by approximately 9-10 dB compared to the 6Mbps 11g, and by approximately 3-4 dB compared to the 1Mbps 11b. Following these design guidelines, an ELR design with 1Mbps can be achieved by employing a simple repetition scheme in the preamble, data fields, and channel coding.With the above design, UHR ELR can achieve a range 10dB longer than 11g at 6Mbps and a range 4dB longer than 11b at 1Mbps. Since the aforementioned link margin imbalance exists in the 2.4GHz, 5GHz, and 6GHz bands, all bands in 11bn (i.e., the 2.4GHz, 5GHz, and 6GHz bands) require ELR PPDU to be enabled.

[0051] Figure 2 This is an interactive schematic diagram of the ELR PPDU indication method of this application. This method 200 is applied to a site device and includes at least the following:

[0052] S200, send an ELR PPDU indication signaling message to the target terminal device, the ELR PPDU indication signaling message being used to indicate whether the target terminal device sends and / or receives an ELR PPDU.

[0053] The ELR PPDU indication method provided in this application sends ELR PPDU indication signaling to the target terminal device through the site device to indicate whether the target terminal device sends and / or receives ELR PPDUs. This enables the target terminal device, which is undergoing changes, to promptly start or stop its ELR PPDU receiving / transmission strategy, adapt to the changing needs of the terminal device, and avoid resource waste or poor communication signal.

[0054] It is understood that the aforementioned target terminal device can be one or multiple, and the site device can simultaneously instruct multiple target terminal devices to start or stop the ELR PPDU reception / transmission strategy.

[0055] In some embodiments, the site device may send an ELR PPDU indication signaling to the target terminal device to initiate the transmission and / or reception of ELR PPDUs when it determines that the signal energy / signal power with the target terminal device is less than a preset threshold; and send an ELR PPDU indication signaling to the target terminal device to stop the transmission and / or reception of ELR PPDUs when it determines that the signal energy / signal power with the target terminal device is greater than or equal to the preset threshold.

[0056] In some embodiments, the site device may send an ELR PPDU indication signaling to the target terminal device to initiate the transmission and / or reception of ELR PPDUs when it determines that the communication error rate with the target terminal device is greater than a set error rate; and send an ELR PPDU indication signaling to the target terminal device to stop the transmission and / or reception of ELR PPDUs when it determines that the communication error rate with the target terminal device is less than or equal to the set error rate.

[0057] In some embodiments, the ELR PPDU indication signaling is used to instruct the target terminal device to enable or disable the ELR PPDU transmission and / or reception functions.

[0058] It is understood that in this embodiment, the target terminal device is a device that has already been pre-configured with ELR PPDU capability. Therefore, the site device only needs to send an ELR PPDU indication signaling to it, informing these target terminal devices whether to enable or disable the ELR PPDU transmission and / or reception function. Enabling the ELR PPDU transmission and / or reception function indicates that the target terminal device starts / begins the ELR PPDU transmission and / or reception function, while disabling the ELR PPDU transmission and / or reception function indicates that the ELR PPDU transmission and / or reception function is stopped / terminated.

[0059] In some embodiments, the ELR PPDU indication signaling is used to instruct the target terminal device to send and / or receive the ELR PPDU according to the configuration information in the ELR PPDU indication signaling.

[0060] It is understood that in this embodiment, the target terminal device does not have or has no preset ELR PPDU capability, and the site device needs to send an ELR PPDU indication signaling containing configuration information for activating ELR PPDU to the target terminal device so that the target terminal device receives and / or sends ELR PPDU according to the configuration information.

[0061] Specifically, the configuration information includes one or more of the following: transmission bandwidth, uplink / downlink indication, number of transmission streams, transmission duration, transmission power, transmission MCS, and frame structure of the ELR PPDU. This instructs the target terminal device to receive and / or transmit the ELR PPDU according to the specified parameters. It is understood that the configuration information described here applies only to ELR PPDUs. It is worth noting that in actual use, all features may be used, or only one or some features may be used.

[0062] In some embodiments, the ELR PPDU indication signaling is carried in a MU PPDU frame and transmitted.

[0063] This embodiment primarily instructs the target terminal device to receive or not receive ELR PPDUs according to the ELR PPDU indication signaling, i.e., it is applied on the downlink between the AP and the non-AP STA. It is worth noting that the ELR PPDU indication signaling is carried in the MUPPDU frame. This means that when the target terminal device receives a MUPPDU frame, if the ELR PPDU indication signaling carried in that frame indicates enabling the transmission and / or reception of ELR PPDUs, then the target terminal device receives the MUPPDU frame with the capability or configuration to receive ELR PPDUs. The target terminal device can also send ELR PPDUs during subsequent uplink data transmission.

[0064] like Figure 3The MU PPDU frame format shown typically includes L-SIF (Non-HT Short Training field), L-LTF (Non-HT Long Training field), L-SIG (Non-HT SIGNAL field), RL-SIG (Repeated Non-HT SIGNAL field), U-SIG (Universal SIGNAL field), ETH-SIG (ETHSIGNAL field), ETH-SIF (ETH Short Training field), ETH-LTF (ETH Long Training field), Data, and PE (Packet Extension field). In this embodiment, the ELR PPDU indication signaling is carried in the U-SIG field of the MU PPDU frame. The U-SIG field further includes U-SIG-1 and U-SIG-2 fields. The U-SIG-1 field includes PHY Version Identifier (3 bits), Bandwidth (3 bits), UL / DL (uplink / downlink, 1 bit), BSS Color (baseband subsystem color, 6 bits), TXOP (Transmission Opportunity, 7 bits), Disregard (5 bits), and Validata (1 bit). The U-SIG-2 field includes PPDU Type and Compression Mode (2 bits), Validata (1 bit), Punctured Channel Information (5 bits), Validata (1 bit), ETH-SIG MCS (ETH-SIG series, 2 bits), Number of ETH-SIG Symbols (5 bits), CRC (Cyclic Checksum, 4 bits), and Tail (6 bits).

[0065] Specifically, in some embodiments, the ELR PPDU indication signaling is implemented through the value of the PHY Version Identifier in the U-SIG field of the MU PPDU frame.

[0066] Furthermore, in some embodiments, when the ELR PPDU indication signaling is used to instruct the target terminal device to enable the transmission and / or reception function of ELR PPDU, the PHY Version Identifier takes one of the following values: PHY Version Identifier = 2; PHY Version Identifier = 3; PHY Version Identifier = 4; PHY Version Identifier = 5; PHY Version Identifier = 6; PHY Version Identifier = 7. When the ELR PPDU indication signaling is used to instruct the target terminal device to disable the transmission and / or reception function of ELR PPDU, the PHY Version Identifier = 0 or 1. That is, the potential combinations for indicating reception / transmission of ELR PPDU are shown in Table 1 below, and the potential combinations for indicating non-reception / transmission of ELR PPDU are shown in Table 2 below. This embodiment can achieve ELR PPDU indication to the target terminal device simply by configuring the value of PHY Version Identifier in the MUPPDU frame, which is simple to implement and has low overhead.

[0067] Table 1 shows the potential combinations of ELR PPDU indications implemented using the PHY Version Identifier value in the MU PPDU frame.

[0068] Potential combinations of receive / transmit ELR PPDU PHY Version Identifier value Potential combination 1 PHY Version Identifier = 2 Potential combination 2 PHY Version Identifier = 3 Potential combination 3 PHY Version Identifier = 4 Potential Combination 4 PHY Version Identifier = 5 Potential combination 5 PHY Version Identifier = 6 Potential Combination 6 PHY Version Identifier = 7

[0069] Table 2 shows the potential combinations of ELR PPDU indications implemented using the PHY Version Identifier values ​​in the MU PPDU frame.

[0070] Potential combinations of not receiving / sending ELR PPDU PHY Version Identifier value Potential combination 1 PHY Version Identifier=0 or 1

[0071] In some embodiments, the ELR PPDU indication signaling is implemented by configuring the value of the PHY VersionIdentifier and the value of at least one bit of the Disregard field in the MU PPDU frame.

[0072] As the analysis of the MU PPDU frame above shows, the Disregard field occupies 5 bits. To save overhead, only one bit of this field can be used in conjunction with the PHY Version Identifier to implement the ELR PPDU indication signaling. It is understandable that using the PHY Version Identifier and the Disregard field together to implement the ELR PPDU indication signaling can improve the accuracy of the signaling and achieve ELR PPDU indication with minimal modifications to the existing standard.

[0073] Optionally, in some embodiments, multiple bits of the Disregard field and the PHYVersion Identifier can be used together to implement the ELR PPDU indication signaling, such as 2 bits, 3 bits, 4 bits, ... or all 5 bits, with the Disregard field ranging from 0 to 31.

[0074] Specifically, in some embodiments, as shown in Table 3 below, when the ELR PPDU indication signaling is used to instruct the target terminal device to enable the transmission and / or reception function of the ELR PPDU, the PHY Version Identifier = 1, and a specific bit of the Disregard field is set to 1. As shown in Table 4 below, when the ELR PPDU indication signaling is used to instruct the target terminal device to disable the transmission and / or reception function of the ELR PPDU, the PHY Version Identifier = 1, and a specific bit of the Disregard field is set to 0.

[0075] Table 3 shows the potential combinations of ELRPDU indications achieved using the PHY Version Identifier and Disregard field values ​​in the MU PPDU frame.

[0076]

[0077] Table 4 shows the potential combinations of ELRPDU indications achieved using the PHY Version Identifier and Disregard field values ​​in the MU PPDU frame.

[0078]

[0079] In some embodiments, as shown in Table 5 below, when the ELR PPDU indication signaling is used to instruct the target terminal device to enable the transmission and / or reception function of the ELR PPDU, the PHY Version Identifier = 1, and the specific bit of the Disregard field is 0. As shown in Table 6 below, when the ELR PPDU indication signaling is used to instruct the target terminal device to disable the transmission and / or reception function of the ELR PPDU, the PHY Version Identifier = 1, and the specific bit of the Disregard field is 1.

[0080] Table 5 shows the potential combinations of ELRPDU indications achieved using the PHY Version Identifier and Disregard field values ​​in the MU PPDU frame.

[0081]

[0082] Table 6 shows the potential combinations of ELRPDU indications achieved using the PHY Version Identifier and Disregard field values ​​in the MU PPDU frame.

[0083]

[0084]

[0085] Furthermore, this can also be achieved by configuring the value of the PHY Version Identifier and the value of all or part of the Disregard field bits in the MU PPDU frame. That is, when the ELR PPDU indication signaling is used to instruct the target terminal device to enable the ELR PPDU transmission and / or reception function, the ELR PPDU indication signaling uses PHYVersion Identifier = 1 and the Disregard field is any value from 0 to 31.

[0086] In some embodiments, the ELR PPDU indication signaling is further implemented by configuring the values ​​of PPDU TypeAnd Compression Mode and UL / DL in the MU PPDU frame.

[0087] In addition to the fields in the aforementioned embodiments, PPDU Type And Compression Mode and UL / DL can also be used to jointly implement ELR PPDU indication signaling.

[0088] Optionally, as shown in Tables 7 and 8, when the ELR PPDU indication signaling is used to instruct the target terminal device to enable the transmission and / or reception functions of the ELR PPDU, the values ​​of PPDU Type And Compression Mode and UL / DL are one of the following: DL = 0, PPDU Type And Compression Mode = 3; UL = 1, PPDU Type And Compression Mode = 2 or 3. Other values ​​of PPDU Type And Compression Mode and UL / DL indicate that the ELR PPDU indication signaling is used to instruct the target terminal device to disable the ELR PPDU.

[0089] Table 7 shows the potential combinations of ELRPDU indications achieved using the PPDU Type and Compression Mode and UL / DL values ​​in the MU PPDU frame.

[0090]

[0091] Table 8 shows the potential combinations of ELRPDU indications achieved using the PPDU Type and Compression Mode and UL / DL values ​​in the MU PPDU frame.

[0092]

[0093] In some embodiments, the ELR PPDU indication signaling is implemented by configuring the modulation scheme of at least one OFDM symbol in the U-SIG field. Optionally, the ELR PPDU indication signaling is implemented by configuring the modulation scheme of one OFDM symbol in the U-SIG field, which can minimize interference with OFDM symbol encoding. Furthermore, when the ELR PPDU indication signaling is used to instruct the target terminal device to enable the transmission and / or reception function of the ELR PPDU, the modulation scheme of the second OFDM symbol in the U-SIG field is QBPSK (Quadrature Binary Phase Shift Keying). It is understood that if the modulation scheme of the second OFDM symbol is not QBPSK, it indicates that the ELR PPDU indication signaling is used to instruct the target terminal device to disable the transmission and / or reception function of the ELR PPDU.

[0094] In some embodiments, the ELR PPDU indication signaling is implemented by configuring the value of the PHY Version Identifier in the U-SIG field and the value of the Disregard field in the UHR-SIG field of the MU PPDU frame.

[0095] In some embodiments, when the ELR PPDU indication signaling is used to instruct the target terminal device to enable the transmission and / or reception function of the ELRPPDU, the PHY Version Identifier of the U-SIG field is 1, and a specific bit of the Disregard field in the UHR-SIG field is 0 or 1; or the PHY Version Identifier of the U-SIG field is 1, and the Disregard field in the UHR-SIG field is any value from 0 to a specific range, for example, the specific range is 0 to 31.

[0096] It's worth noting that the UHR-SIG (Ultra-High Reliability-SIGNAL) field and the U-SIG (Universal SIGNAL) field are not the same. They use different values ​​to work together to implement the ELR PPDU indication. UHR-SIG is a name defined in WI-FI8 (802.11be), which is based on ETH-SIG in WI-FI7 (802.11ax) and inherits related content from ETH-SIG.

[0097] In some embodiments, the ELR PPDU indication signaling is carried and transmitted in a Trigger frame. In some embodiments, the ELR PPDU indication signaling is carried and transmitted in a Special User Info field within a Trigger frame. The format of the Special User Info field in the Trigger frame is as follows: Figure 4As shown, it includes AID12 (12 bits), PHY VersionIdentifier (3 bits), UL Bandwidth Extension (2 bits), ETH Spatial Reuse 1 (4 bits), ETH Spatial Reuse 2 (4 bits), U-SIG Disregard And Valid (12 bits), Reserved (3 bits), and Trigger Dependent User Info (random variable).

[0098] This embodiment primarily instructs the target terminal device to send or not send ELR PPDUs according to the ELR PPDU indication signaling, i.e., it is applied on the uplink between the AP and the non-AP STA. It is worth noting that the ELR PPDU indication signaling is carried in the Trigger frame. This means that when the target terminal device receives the Trigger frame, if the ELR PPDU indication signaling carried in the Trigger frame indicates that the transmission and / or reception of ELR PPDUs is enabled, then the target terminal device will subsequently send TB PPDU frames with the capability or configuration of ELR PPDUs.

[0099] In some embodiments, the ELR PPDU indication signaling is implemented by configuring the value of the PHY Version Identifier in the Special UserInfo field of the Trigger frame.

[0100] Optionally, in some embodiments, when the ELR PPDU indication signaling is used to instruct the target terminal device to enable the transmission and / or reception function of ELR PPDU, as shown in Table 9 below, the PHY Version Identifier takes one of the following values: PHY Version Identifier = 2; PHY Version Identifier = 3; PHY Version Identifier = 4; PHY Version Identifier = 5; PHY Version Identifier = 6; PHY Version Identifier = 7. When the ELR PPDU indication signaling is used to instruct the target terminal device to disable the transmission and / or reception function of ELR PPDU, as shown in Table 10 below, the PHY Version Identifier = 0 or 1. This embodiment can achieve ELRPPDU indication to the target terminal device simply by configuring the value of PHY Version Identifier in the Trigger frame, which is simple to implement and has low overhead.

[0101] Table 9 shows the potential combinations of ELR PPDU indications implemented using the PHY Version Identifier value in the Trigger frame.

[0102] Potential combinations of receive / transmit ELR PPDU PHY Version Identifier value Potential combination 1 PHY Version Identifier = 2 Potential combination 2 PHY Version Identifier = 3 Potential combination 3 PHY Version Identifier = 4 Potential Combination 4 PHY Version Identifier = 5 Potential combination 5 PHY Version Identifier = 6 Potential Combination 6 PHY Version Identifier = 7

[0103] Table 10 shows the potential combinations of ELR PPDU indications implemented using the PHY Version Identifier value in the Trigger frame.

[0104] Potential combinations of not receiving / sending ELR PPDU PHY Version Identifier value Potential combination 1 PHY Version Identifier=0 or 1

[0105] In some embodiments, the ELR PPDU indication signaling is implemented by configuring the value of the PHY VersionIdentifier and the value of at least one bit of U-SIG Disregard and Validate in the Trigger frame.

[0106] As the analysis of the Trigger frame above shows, the U-SIG Disregard and Validate occupies 12 bits. To save overhead, only one bit can be used in conjunction with the PHY Version Identifier to implement the ELR PPDU indication signaling. It is understandable that using the PHY Version Identifier and U-SIG Disregard and Validate together to implement the ELR PPDU indication signaling can improve the accuracy of the signaling and achieve ELR PPDU indication with minimal modifications to the existing standard.

[0107] Optionally, in some embodiments, the values ​​of multiple bits of U-SIG Disregard and Validate and PHY Version Identifier can be used together to implement ELR PPDU indication signaling, such as 2 bits, 3 bits, 4 bits, ... or all 12 bits. The value range of U-SIG Disregard and Validate is 0 to 4095 (such as Validate in U-SIG-2, which includes 1 bit).

[0108] In some embodiments, as shown in Table 11 below, when the ELR PPDU indication signaling is used to instruct the target terminal device to enable the transmission and / or reception function of the ELR PPDU, the PHY Version Identifier = 1, and the specific bit of the U-SIG Disregard and Validate is set to 1. As shown in Table 12 below, when the ELR PPDU indication signaling is used to instruct the target terminal device to disable the transmission and / or reception function of the ELR PPDU, the PHY Version Identifier = 1, and the specific bit of the U-SIG Disregard and Validated is set to 0.

[0109] Table 11 shows the potential combinations of ELR PPDU indications implemented using the PHY Version Identifier and U-SIG Disregard and Validate values ​​in the Trigger frame.

[0110]

[0111] Table 12 shows potential combinations of ELR PPDU indications implemented using the PHY Version Identifier and U-SIG Disregard and Validate values ​​in the Trigger frame.

[0112]

[0113] In some embodiments, as shown in Table 13, when the ELR PPDU indication signaling is used to instruct the target terminal device to enable the transmission and / or reception function of the ELR PPDU, the PHY Version Identifier = 1, and the specific bit of the U-SIG Disregard and Validate is 0. As shown in Table 14, when the ELR PPDU indication signaling is used to instruct the target terminal device to disable the transmission and / or reception function of the ELR PPDU, the PHY Version Identifier = 1, and the specific bit of the U-SIG Disregard and Validate is 1.

[0114] Table 13 shows potential combinations of ELR PPDU indications implemented using the PHY Version Identifier and U-SIG Disregard and Validate values ​​in the Trigger frame.

[0115]

[0116] Table 14 shows potential combinations of ELR PPDU indications implemented using the PHY Version Identifier and U-SIG Disregard and Validate values ​​in the Trigger frame.

[0117]

[0118] Furthermore, in some embodiments, to improve the accuracy of ELR PPDU indication, the ELR PPDU indication signaling is implemented by configuring the value of PHY Version Identifier and all or part of the bit values ​​of Disregard in U-SIG-1 or Disregard in U-SIG-2 in the Trigger frame.

[0119] Specifically, when the ELR PPDU indication signaling is used to instruct the target terminal device to enable the ELR PPDU transmission and / or reception function, the value of PHY Version Identifier and the value of Disregard in U-SIG-1 or Disregard in U-SIG-2 are one of the following: PHY Version Identifier = 1, and the value of Disregard in U-SIG-1 is any value from 0 to 63; PHY Version Identifier = 1, and the value of Disregard in U-SIG-2 is any value from 0 to 31.

[0120] refer to Figure 5 The U-SIG Disregard and Validate fields further include Disregard in U-SIG-1 (ignoring U-SIG-1, occupying 6 bits), Validate in U-SIG-2 (validating U-SIG-2, occupying 1 bit), and Disregard in U-SIG-2 (ignoring U-SIG-2, occupying 5 bits). Since Disregard in U-SIG-1 occupies 6 bits and its value can be any value from 0 to 63, and Disregard in U-SIG-2 occupies 5 bits and its value can be any value from 0 to 31, it can also be implemented using the value of PHY Version Identifier and all or part of the bit values ​​of Disregard in U-SIG-1 or Disregard in U-SIG-2.

[0121] In some embodiments, the ELR PPDU indication signaling is implemented by configuring the value of the PHY VersionIdentifier and the value of at least one reserved bit in the Trigger frame.

[0122] In addition to using the aforementioned fields in the Trigger frame to implement ELR PPDU indication, the value of PHYVersion Identifier and Reserved in the Trigger frame can also be used to implement ELR PPDU indication. Reserved is a reserved field, and using this field to implement ELR PPDU indication will not cause additional overhead to the Trigger frame.

[0123] In some embodiments, referring to Table 15, when the ELR PPDU indication signaling is used to instruct the target terminal device to enable the transmission and / or reception function of the ELR PPDU, the PHY Version Identifier = 1, and the value of the specific bit of the Reserved is 1. Referring to Table 16, when the ELR PPDU indication signaling is used to instruct the target terminal device to disable the transmission and / or reception function of the ELR PPDU, the PHY Version Identifier = 1, and the value of the specific bit of the Reserved is 0.

[0124] Table 15 shows potential combinations of ELR PPDU indications implemented using the PHY Version Identifier and Reserved values ​​in the Trigger frame.

[0125]

[0126] Table 16 shows potential combinations of ELR PPDU indications implemented using the PHY Version Identifier and Reserved values ​​in the Trigger frame.

[0127]

[0128] In some embodiments, referring to Table 17, when the ELR PPDU indication signaling is used to instruct the target terminal device to enable the transmission and / or reception function of the ELR PPDU, the PHY Version Identifier = 1, and the value of a specific bit of the Reserved bit is 0. Referring to Table 18, when the ELR PPDU indication signaling is used to instruct the target terminal device to disable the transmission and / or reception function of the ELR PPDU, the PHY Version Identifierr = 1, and the value of a specific bit of the Reserved bit is 1.

[0129] Table 17 shows potential combinations of ELR PPDU indications implemented using the PHY Version Identifier and Reserved values ​​in the Trigger frame.

[0130]

[0131] Table 18 shows potential combinations of ELR PPDU indications implemented using the PHY Version Identifier and Reserved values ​​in the Trigger frame.

[0132]

[0133] It is understood that in some embodiments, the value of the PHY Version Identifier and multiple bits of the Reserved field can be used together to implement the ELR PPDU indication signaling, such as 2 bits or 3 bits. The value range of Reserved is 0 to 7.

[0134] In some embodiments, the ELR PPDU indication signaling is configured via the PPDU Type and Compression Mode in the Trigger frame. Figure 4 The PPDU Type and Compression Mode of the Trigger frame are not shown; they are located in the U-SIG field of the Trigger frame (refer to the corresponding structure of the MU PPDU frame) and their values ​​are UL / DL (…). Figure 4 The UL / DL of the Trigger frame is not shown; it is located in the U-SIG field of the Trigger frame (refer to the corresponding structure of the MU PPDU frame for its value).

[0135] Optionally, in some embodiments, as shown in Tables 19 and 20, when the ELR PPDU indication signaling is used to instruct the target terminal device to enable the ELR PPDU transmission and / or reception function, the PPDU Type And Compression Mode and the UL / DL values ​​are one of the following: DL=0, PPDU Type And Compression Mode=3; UL=1, PPDU Type And Compression Mode=2 or 3.

[0136] It is understandable that the PPDU Type And Compression Mode and other values ​​of UL / DL all indicate that the ELRPPDU indication signaling is used to instruct the target terminal device to enable the ELR PPDU.

[0137] Table 19 shows potential combinations of ELRPDU indications using PPDU Type, Compression Mode, and UL / DL values ​​in the Trigger frame.

[0138]

[0139]

[0140] Table 20 shows potential combinations of ELRPDU indications using PPDU Type, Compression Mode, and UL / DL values ​​in the Trigger frame.

[0141]

[0142] In some embodiments, the ELR PPDU indication signaling is implemented by configuring the modulation scheme of at least one OFDM symbol in the U-SIG field of the Trigger frame. Optionally, the ELR PPDU indication signaling is implemented by configuring the modulation scheme of one OFDM symbol in the U-SIG field, which can minimize interference with OFDM symbol encoding. Furthermore, when the ELR PPDU indication signaling is used to instruct the target terminal device to enable the transmission and / or reception function of the ELR PPDU, the modulation scheme of the second OFDM symbol in the U-SIG field is QBPSK (Quadrature Binary Phase Shift Keying). It is understood that if the modulation scheme of the second OFDM symbol is not QBPSK, it indicates that the ELR PPDU indication signaling is used to instruct the target terminal device to disable the transmission and / or reception function of the ELR PPDU.

[0143] It is worth noting that the MU PPDU in the foregoing embodiments can be either UHR MU PPDU or EHT MUPPDU, and the TB PPDU in the foregoing embodiments can be either UHR TB PPDU or EHT TB PPDU. UHR MU PPDU and UHR TB PPDU are the names of MU PPDU and TB PPDU in 802.11bn, and EHT MU PPDU and EHT TB PPDU are the names of MU PPDU and TB PPDU in 802.11be. UHR MU PPDU is inherited from EHT MU PPDU, and UHR TB PPDU is inherited from EHT TB PPDU.

[0144] The ELR PPDU indication method provided in this embodiment sends an ELR PPDU indication signaling message to the target terminal device to indicate whether the target terminal device sends and / or receives ELR PPDUs. This enables the target terminal device, which is undergoing changes, to promptly start or stop its ELR PPDU receiving / transmission strategy, adapting to the changing needs of the terminal device. This not only fills the gap in the current IEEE standard for ELR PPDU indication but also effectively overcomes the problems of resource waste or poor communication signals.

[0145] This application also provides an ELR PPDU indication method, applied to a terminal device, the method including the following:

This not only fills the gap in the current IEEE standard for ELR PPDU indication but also effectively overcomes the problems of resource waste or poor communication signals.
