[0042] The technical solutions in the embodiments of the present application will be described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only some of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative labor fall within the scope of the present application.

[0043] It should be understood that the term "and / or" in this document merely describes an associated relationship between associated objects, which means that there can be three relationships, for example, A and / or B can represent three cases: A exists alone, A and B exist together, and B exists alone. In addition, the character " / " in this document generally represents an "or" relationship between the associated objects before and after it.

[0044] Internet-of-thing (IoT) is a network of device components that collect data, share data with other devices, and communicate through the Internet. This huge device network not only generates data, collects data, and communicates, but also supports intelligent decision-making based on data. The characteristics of supporting remote access, automation, and intelligence make IoT devices widely deployed in applications such as smart home, smart manufacturing, smart agriculture, and warehouse logistics. In these application scenarios, it is extremely challenging to provide continuous power supply and device maintenance for a large number of devices, and IoT devices with extremely low power consumption and super-long life cycle have become a hot research direction. Ambient IoT needs to be composed of self-powered units that can obtain sufficient power from environmental conditions such as light, vibration, and heat to support themselves to get rid of the dependence on power lines and large-capacity batteries.

[0045] IoT devices receive or generate data and then wirelessly transmit it to other devices to perform any given task, which makes the standardization of ultra-low-power IoT devices involve both wireless communication and wireless power transfer (WPT). Based on the communication protocol foundation of the current wireless network WiFi Institute of Electrical and Electronics Engineers (IEEE) 802.11 wireless transmission network, the embodiments of the present application design a cooperative management mechanism for the wireless communication and wireless power transfer link of AMP IoT, which supports the timely switching of transmission modes for Ambient Power (AMP) IoT devices with different device capabilities based on data transmission requirements, while ensuring that the wireless power transfer link supports the smooth completion of wireless transmission, achieving an effective balance and management control of network efficient data transmission and device energy saving.

[0046] The IEEE 802.11BP working group defines two device morphologies in AMP IoT, namely, AMP-only devices and AMP-assisted devices. The AMP-assisted device can be compatible with legacy WiFi networks, devices, has strong capabilities, and supports channel access modes, authentication and association security mechanisms defined in the IEEE 802.11 standard. The AMP-only device is not required to be compatible with legacy devices. AMP IoT devices include: 1. Backscattering-based AMP IoT devices: based on backscattering for wireless communication, without an active transmitter (active TX), cannot actively initiate transmission, and can only rely on the reader for data reading, similar to Radio Frequency Identification (RFID) devices. In the field of AMP technology research in the IEEE 802.11BP standard, backscattering-based devices can support close-range backscattering and long-range backscattering. Backscattering-based AMP IoT devices belong to AMP-assisted devices. 2. AMP non-AP STA with an active transmitter, which can report data without carrier modulation and can directly send wireless frames, but is limited by the minimalist design and low cost of AMP devices, and has poor link budget compared to traditional STA devices. It can access the channel at the AC_BK access level in 2.4GHz and Sub-1GHz. Since it has no or poor energy storage capability, it generally needs the AP to initiate transmission and complete wireless frame interaction within the protection window. Some of the AMP non-AP STA with an active transmitter belong to AMP-assisted devices, and some belong to AMP-only devices.

[0047] The system of the embodiments of the present application includes an AMP AP, an AMP STA, and a wireless energizer (or energizer). The AMP AP can be an AP, a soft AP, a mobile AP, an AP multi-link device (MLD), and a reader defined in the IEEE 802.11BP standard and other related standards, or a functional entity. The AMP STA can be an AMP non-AP STA, an AMP tag, an AMP sticker, an AMP sensor, or an AMP IoT device or functional entity. The wireless energizer can be a functional entity integrated on the AMP AP or the AMP STA, or an independent radio frequency (RF) energy transmission device.

[0048] Currently, the prior art has one or more of the following problems to be solved, and the embodiments of the present application can solve one or more of the following problems of the prior art:

[0049] 1. Asymmetry of transmission capability of AMP-only device: AMP-only devices are generally simple IoT nodes such as tags, stickers, small sensors, etc. Through AMP link budget analysis, it can be determined that the transmission capability of the transmitting end and the receiving end of the AMP IoT device or tag is mismatched. The main reason is that in the uplink process, the receiver capability of the target object AMP reader is very strong, but the receiver sensitivity of the downlink-only AMP device is poor, resulting in poorer reliability, coverage range, etc. of the downlink transmission compared to the uplink transmission. Compared with legacy STAs, under the same traffic load, the link budget of the AMP-only device is poor, which will affect the transmission range of its data sending / receiving, and further affect its compatible coexistence with legacy devices in IEEE 802.11 networks. The embodiments of the present application design a cooperative link management and control mechanism for AMP IoT wireless communication link and wireless power transfer (WPT) link, which can solve the problem of asymmetry of transmission capability of the AMP-only device in the prior art.

[0050] 2. Lack of management and control mechanism for AMP IoT wireless communication link and wireless charging link: The prior art lacks a management and control mechanism for the AMP IoT wireless communication link and the wireless charging link. Unlike the prior art, in the embodiments of the present application, the application of the Multi-Link Operation (MLO) management mechanism, in the AMP scenario, the AMP capability is diverse, the transmission mode is diverse, the device form is diverse, and a new wireless power transfer (WPT) link is introduced. The transmission optional mode includes near distance backscattering, long distance backscattering, active transmission and compatibility transmission mode, etc. Different capabilities and different transmission modes need to flexibly manage and configure the wireless power transfer link and the wireless communication link, and the management and configuration are based on different device capabilities, which may be dominated by the AMP AP decision or may be self-decided by the AMP STA, and the wireless power transfer link needs to be managed in real time. Cooperate to manage the wireless power transfer link to configure the wireless power transfer link according to the transmission demand or further decide the transmission mode of the data transmission link according to the configuration of the wireless power transfer. The embodiments of the present application design a cooperative link management and control mechanism that meets the characteristics of AMP IoT devices, which can effectively solve the problem of interference of the wireless power transfer link to the data link.

[0051] 3. Unidirectional energy saving management of energy sensitive device: for AMP STA, due to its limited environmental energy charging and its own low device capability, its device should avoid high-capability frame exchange process as much as possible. Unlike the decision of the traditional device for its energy saving state and the switching of the downlink high capability, and the existing energy saving mode for the advance declaration of the energy saving state and the wake-up mechanism, the AMP STA has few downlink data transmission scenarios, and only has high-capability transmission demand in uplink data. The embodiments of the present application design a cooperative link management and control mechanism in line with the characteristics of AMP IoT device, a unidirectional energy saving management mechanism of AMP IoT, and the initiation of high-capability transmission of AMP STA should be triggered and instructed by AMP AP, and the downlink of AMP IoT should not allow high-capability transmission to occur. Based on the special unidirectional energy saving management mode, the extreme energy saving effect of energy sensitive device is realized.

[0053] FIG. 1B is a flowchart of a wireless energy transmission and wireless communication cooperative management method provided by an embodiment of the present application. As shown in FIG. 1B, the wireless energy transmission and wireless communication cooperative management method is executed in a station (STA), wherein the wireless energy transmission and wireless communication cooperative management method includes at least one operation: operation 101B: based on parameters and / or states of wireless energy transmission configuration between an access point (AP) or the STA and a wireless energy transmission node, or based on a wireless energy transmission link established between the AP and the wireless energy transmission node, the STA performs management and control of a wireless communication link between the AP and the STA, and / or based on transmission requirements of the wireless communication link, the STA performs management of the wireless energy transmission link in a manner instructed or negotiated by the AP or the STA to the wireless energy transmission node.

[0054] Through the technical solution, the Ambient Power (AMP) Internet-of-thing (IoT) device with different device capabilities can perform timely switching of a transmission mode based on data transmission requirements, so that the wireless power transmission link supports wireless transmission, efficient data transmission of the network is realized, and effective balance and management control of device energy saving are achieved.

[0055] In some embodiments of the present application, the management and control of the wireless communication link includes management and control of wireless communication scheduling, wireless communication transmission mode, and / or wireless communication transmission parameter. In some embodiments of the present application, the transmission requirement of the wireless communication link includes transmission requirement of wireless communication data transmission mode, transmission parameter, and / or transmission scheduling. In some embodiments of the present application, the management of the wireless power transmission link includes parameter configuration of the wireless power transmission link, state reporting of the wireless power transmission link, configuration parameter reporting of the wireless power transmission link, state modification of the wireless power transmission link, and / or configuration parameter modification of the wireless power transmission link.

[0056] The embodiments of the present application support backscattering AMP devices, AMP STAs with active transmitters, and AMP MLDs based on data reporting requirements of transmission mode and wireless power transmission link management mechanism.

[0057] In some embodiments of the present application, based on the parameters and states of the wireless power transmission configuration between the AMP AP or AMP non-AP STA and the wireless power transmission node, or based on the established wireless power transmission link between the AMP AP and the wireless power transmission node, the AMP AP manages and controls the wireless transmission link, including management and control of wireless communication scheduling, wireless communication transmission mode, and wireless communication transmission parameter.

[0058] In some embodiments of the present application, based on the transmission requirements such as wireless communication data transmission mode, transmission parameter, and / or transmission scheduling between the AMP AP and the AMP non-AP STA, the AMP AP or the AMP non-AP STA manages the configuration and state of the wireless power transmission in a manner of indication or negotiation to the wireless power transmission node.

[0059] In some embodiments of the present application, considering different device capabilities and different device forms of the AMP STA (AP or non-AP), the management mechanism of the wireless power transfer and the wireless transmission link can support the following implementation modes: the AMP non-AP STA and / or the AMP wireless power transfer node completely decides by itself; the AMP non-AP STA and / or the AMP wireless power transfer node negotiates with the AMP AP; the AMP non-AP STA and / or the AMP wireless power transfer node completely relies on the indication of the AMP AP.

[0060] In some embodiments of the present application, the following first solution, second solution, and third solution are designed.

[0061] First solution: link control based on transmission mode with active transmitter.

[0062] FIG. 2A is a schematic diagram of a network topology of an AMP AP, an AMP STA, and a wireless energy transfer node according to an embodiment of the present application. In some embodiments of the present application, as shown in FIG. 2A, a first solution is a network topology of an AMP IoT, in which a wireless energy transfer management control link is established between an AMP AP and a wireless energy transfer node, and a wireless communication link is established between the AMP AP and an AMP STA. In some embodiments of the present application, based on different AMP STA device capabilities and / or wireless communication working modes supported by a basic service set (BSS), wireless communication between the AMP AP and the AMP STA can be through a symmetric, asymmetric, or relayed manner. In some embodiments of the present application, wireless communication between the AMP AP and the AMP STA is implemented through an asymmetric wireless communication manner, which means that an uplink between the AMP AP and the AMP STA has a first wireless transmission parameter, a downlink between the AMP AP and the AMP STA has a second wireless transmission parameter, and the first wireless transmission parameter and the second wireless transmission parameter are not completely consistent. In some embodiments of the present application, the first wireless transmission parameter and / or the second wireless transmission parameter includes a bandwidth, a frequency band, a center frequency point, a data rate, a spatial stream, a modulation and coding scheme (MCS), and / or a link budget, etc. In other words, as long as one of the above-mentioned parameters is different between the uplink and the downlink, it is an asymmetric wireless communication manner. In some embodiments of the present application, wireless communication between the AMP AP and the AMP STA is implemented through a symmetric wireless communication manner, which means that an uplink between the AMP AP and the AMP STA has a first wireless transmission parameter, a downlink between the AMP AP and the AMP STA has a second wireless transmission parameter, and the first wireless transmission parameter and the second wireless transmission parameter are completely consistent. In other words, as long as all of the above-mentioned parameters are consistent between the uplink and the downlink, it is a symmetric wireless communication manner.

[0063] Since the AMP STA takes energy from the environment, communication energy saving is its key feature, and the AMP STA that can support energy saving operation can switch among various transmission modes to reduce the duration of high-capability transmission mode or device on state as much as possible to reduce energy consumption. The AMP AP and the wireless energy transfer node establish a wireless energy transfer management control link to configure, negotiate, update, query, report, and the like of the state and parameters of the wireless energy transfer.

[0064] In some embodiments of the present application, when the AMP IoT performs wireless communication, a cooperative management mechanism is performed among the AMP AP, the wireless energy transfer node, and the AMP STA, including two aspects.

[0065] The first aspect: based on the parameters and / or state configured by the wireless energy transfer, or based on the wireless energy transfer link, the wireless communication link is managed and controlled.

[0066] FIG. 2B is a flowchart of a wireless energy transfer and wireless communication cooperative management mechanism according to an embodiment of the present application. In some embodiments of the present application, as shown in FIG. 2B, based on the parameters and / or state configured by the wireless energy transfer, or based on the wireless energy transfer link, the wireless communication link is managed and controlled, including: 1. The AMP STA and the AMP AP negotiate and manage the state or parameters of the wireless energy transfer and the communication link transmission. 2. The AMP AP indicates and triggers the uplink data report through a control frame, and the indication content includes the protection window information of this transmission, the data type of the report, the transmission mode of this data uplink, etc., and the control frame transmission is by default in a low-capability transmission mode. The AMP STA directly switches the transmission mode based on the transmission indication of the AMP AP. 3. The AMP STA decides the switching of the device state or transmission mode according to the power condition of the device itself, the charging link configuration, the uplink transmission buffer, and the like.

[0067] The second aspect: based on the transmission demand of the wireless communication link, the wireless energy transfer link is managed in a manner of indication or negotiation of the wireless energy transfer node by the AMP AP or the AMP STA.

[0068] FIG. 2C is a flowchart of a wireless energy transfer and wireless communication cooperative management mechanism according to an embodiment of the present application. In some embodiments of the present application, as shown in FIG. 2C, based on the transmission demand of the wireless communication link, the wireless energy transfer link is managed in a manner of indication or negotiation of the wireless energy transfer node by the AMP AP or the AMP STA, including: 1. The wireless energy transfer node decides the state or parameters of the wireless energy transfer according to the scheduling and the wireless communication demand. 2. The AMP STA or the AMP AP negotiates the state or parameters of the wireless energy transfer with the wireless energy transfer node in real time according to the wireless communication demand.

[0069] The second solution is a cross-link management method based on an AMP MLD.

[0070] For a powerful AMP AP or AMP STA, such as an AMP auxiliary device, which needs to coexist compatibly with a conventional device under an IEEE 802.11 network, can be a multi-link device (MLD), has the ability to compete for access to a channel, and can prolong the standby time of the device to a certain extent based on energy drawn from the environment. Based on the first solution, combined with multi-link operation (MLO), the cooperative management of wireless energy transmission and wireless communication can be further refined. By further dividing the wireless communication link into a control link and a data link, the separation of control signaling and data signaling is achieved. Only the data link adopts a high-rate or high-throughput transmission mode, and the data link does not need to perform any listening operation. Through the cooperative management of cross links, more extreme network energy saving is achieved.

[0071] The wireless energy transmission and wireless communication cooperative management method of the embodiments of the present application is applicable to an AMP MLD, and achieves management and control of a cross-link wireless communication link and / or management of a wireless energy transmission link. The cooperative link management mechanism of the embodiments of the present application includes a control link, a data link, and a wireless energy management link based on a scheduling or dynamic management method. It is considered that an AMP IoT generally does not have buffered data for downlink, and the affiliated STA of the control link supports doze, listening, and low-capability transmission mode, that is, the frames of the downlink are transmitted by default in the low-capability transmission mode of the AMP STA. The affiliated STA of the data link does not need to perform listening, and remains in a doze state most of the time, and completes transmission mode switching and data reporting according to the control frames received on the control link, that is, the affiliated STA of the data link only supports a doze state and a high-capability state.

[0072] FIG. 3A is a flow diagram of a network topology based on an AMP MLD provided by the embodiments of the present application. As shown in FIG. 3A, the cooperative management mechanism based on an MLD includes establishment of a control link and a data link by an AMP AP MLD and an AMP non-AP MLD, establishment of a wireless energy management control link by the AMP AP MLD and a wireless energy transmission node, and establishment of a wireless energy management link by the wireless energy transmission node and any affiliated AP without limitation.

[0073] Figure 3B is a flow diagram of a network topology based on AMP MLD according to an embodiment of the present application. As shown in Figure 3B, the MLD-based collaborative management mechanism includes that the AMP AP MLD and the AMP non-AP MLD establish a data link, and the AMP AP MLD and the wireless energy transfer node establish a control management link, and the wireless energy transfer node and the AMP non-AP MLD establish a control link. In this method, the AMP non-AP MLD can directly negotiate wireless energy transfer with the wireless energy transfer node through the control link.

[0074] Figure 3C is a flow diagram of a network topology based on AMP MLD according to an embodiment of the present application. As shown in Figure 3C, the MLD-based collaborative management mechanism includes that the AMP AP MLD and the AMP non-AP MLD establish a data link, and the AMP AP MLD and the wireless energy transfer node establish a wireless energy transfer management link, and the MLD's affiliated STA and the AMP non-AP MLD establish a control link. In this method, the AMP non-AP MLD can directly negotiate parameters and state of cross-link wireless energy transfer with the wireless energy transfer node through the control link.

[0075] Figure 3D is a flow diagram of a network topology based on AMP MLD according to an embodiment of the present application. As shown in Figure 3D, the MLD-based collaborative management mechanism includes that the Extremely High Throughput (EHT) / Ultra High Reliability (UHR) AP MLD and the AMP non-AP MLD: for a bandwidth below 1GHz (S1G) link needs to communicate through a relay node, wherein the relay node can simultaneously act as a wireless energy transfer node.

[0076] The third solution is a backscattering-based management method.

[0077] For the AMP network topology under the backscattering scheme, whether in the close range or long range backscattering transmission mode, the link budget is mainly limited by the wireless energy transmission link. The AMP non-AP STA / tag can only receive the management control signaling of the AMP AP / reader and complete the modulation uplink of data based on the carrier signal in the presence of a real-time RF energizing signal. FIG. 4A is a flowchart of a wireless energy transmission and wireless transmission management mechanism based on backscattering provided by an embodiment of the present application, and FIG. 4B is a flowchart of a wireless energy transmission and wireless transmission management mechanism based on backscattering provided by an embodiment of the present application. The third solution includes two methods of wireless energy transmission node integrated with reader and wireless energy transmission node separated from reader. The wireless energy transmission node integrated with the reader is shown in FIG. 4A, and the wireless energy transmission node separated from the reader is shown in FIG. 4B. In some embodiments of the present application, the AP is a backscattering-enabled AMP AP, the STA is a backscattering-enabled AMP STA, the wireless energy transmission node is integrated with the AP, or the wireless energy transmission node is separated from the AP.

[0078] In the backscattering transmission mode, the AMP non-AP STA device has low capability, and the device state is only on or off, and the off state includes, for example, a doze state. The device does not seek compatible coexistence with the conventional device under the IEEE 802.11 network and cannot actively initiate transmission / frame exchange. The management control is completely completed by the AMP AP / reader, that is, the AMP STA does not have the capability of self-determining or negotiating the charging configuration and does not have the capability of self-determining the switching of the device state. The energizing signal of the wireless energy transmission is the wake-up signal, and the AMP STA switches the on state or the off state according to whether the energizing signal or the carrier PPDU is received. The operation of the AMP AP includes wake-up, message response, data reading, etc. The message response of the AMP tag or STA to the AMP reader or AP can include a state query response, a capability query response, etc. Some embodiments of the present application take the state query response as an example, but the control signaling sent by the AMP AP / reader and the response information fed back by the AMP STA / tag are not limited.

[0079] In some embodiments of the present application, the scheme of the first embodiment can be implemented in cooperation with the scheme of the second embodiment and / or the third embodiment, or can be implemented independently of the scheme of the second embodiment and / or the third embodiment. The fourth embodiment to the fourteenth embodiment are examples of the cooperative management mechanism implemented in cooperation with the first embodiment, the second embodiment and / or the third embodiment, and the cooperative management mechanism in actual cases is not limited to the fourth embodiment to the fourteenth embodiment.

[0082] In some embodiments of the present application, the operating frequency band of the AMP STA can include Sub-1GHz, 2.4GHz, etc., and the AMP BSS operation should include symmetric wireless communication operation and asymmetric wireless communication operation. For the AMP STA with asymmetric transmission capability, the transmission (TX) and reception (RX) operate on different frequency channels, such as the transmission operating on a Sub-1GHz channel and the reception operating on a 2.4GHz channel, which can effectively improve the coverage range of the downlink transmission and improve the link budget. The parameters such as the channel, bandwidth, and MCS of the AMP BSS operation related should be indicated by the BSS operation related field, and there are two indication methods:

[0083] Method 1: Indicating the AMP BSS operating parameters by the AMP operation element:

[0084] In some embodiments of the present application, the AMP AP sends a management frame and / or a control frame to the AMP STA, the management frame and / or the control frame being used to indicate the operation parameters of the AMP BSS. In some embodiments of the present application, the management frame and / or the control frame comprises an AMP operation element, a first operation element, or a second operation element, the AMP operation element, the first operation element, or the second operation element being used to indicate the operation parameters of the AMP BSS. FIG. 5A is a schematic diagram of the AMP operation element according to an embodiment of the present application. In some embodiments of the present application, as shown in FIG. 5A, the AMP operation element comprises one or more of the following fields: an Element ID field, used to indicate the ID of the AMP operation element, for distinguishing from other elements defined by IEEE 802.11; a Length field, used to indicate the number of octets of the AMP operation element, i.e. to indicate the field length information of the element; an AMP Operation Information field, used to indicate the operation information of the AMP BSS; a Modulation and Coding Scheme and Number of Spatial Streams Set (MCS and NSS Set) field, used to indicate the MCS (group) information supported by the AMP STAs (AP and non-AP) in the AMP BSS, which can be indicated by a list, a bitmap, an interval indicated by a maximum MCS (Max MCS) and a minimum MCS (min MCS), etc. In some embodiments of the present application, the AMP Operation Information field comprises one or more of the following subfields: an AMP protection subfield, used to indicate the protection requirement of the AMP transmission; a Channel width subfield, used to indicate the channel bandwidth of the operation of the AMP BSS; a Channel number subfield, used to indicate the number of channels of the operation of the AMP BSS; an Operation class subfield, used to indicate the operation class of the operation of the AMP BSS, which is related to the wireless frequency band management regulations of each country / region; a Channel Centre frequency subfield, used to indicate the channel centre frequency of the operation of the AMP BSS.

[0085] In some embodiments of the present application, the protection requirement of the AMP transmission includes one or more of the following protection requirements: unprotected communication, supporting unprotected communication of the AMP STA, i.e. AMP STA self-determining data transmission, wireless transmission through broadcast, without protection window allocation and indication by the AMP AP; AMP protected communication, supporting AMP protected communication, triggering of unicast or groupcast of AMP wireless communication by the AMP AP, indicating protection window information, within the protection window, non-indicated AMP STA or AMP STA group is not allowed to access the channel for wireless frame transmission; AMP and non-AMP STA hybrid communication, supporting hybrid communication of the STA and the non-AMP STA, triggering of unicast, groupcast or broadcast of AMP wireless communication by the AMP AP, indicating protection window information, within the protection window, other STAs (such as high throughput rate HT, high efficiency HE, and extremely high throughput rate EHT STAs) of non-AMP STAs are not allowed to access the channel for wireless frame transmission.

[0086] In some embodiments of the present application, the AMP protection (AMP protection) subfield indicates the protection requirement of the AMP transmission, including unprotected communication, AMP protected communication, AMP and non-AMP STA hybrid communication, etc., as shown in Table 1, with different values (values) for different protection capabilities.

[0088] In some embodiments of the present application, the unprotected communication is indicated by a first value of the AMP protection field, the AMP protected communication is indicated by a second value of the AMP protection field, and / or the AMP and non-AMP STA mixed communication is indicated by a third value of the AMP protection field. The first value is, for example, 0, the second value is, for example, 1, and the third value is, for example, 2. In some embodiments of the present application, supporting the unprotected communication of the STA means that the STA decides by itself to transmit data and performs wireless transmission by broadcasting. In some embodiments of the present application, supporting the AMP protected communication means that the AP triggers unicast or groupcast of the AMP wireless communication, the unicast or the groupcast indicates protection window information, and the protection window information indicates that non-indicated STAs or STA groups are not allowed to access the channel to perform wireless frame transmission within the protection window. In some embodiments of the present application, supporting the STA and the non-AMP STA mixed communication means that the AP triggers unicast or groupcast of the AMP wireless communication, the unicast or the groupcast indicates protection window information, and the protection window information indicates that non-indicated STAs or STA groups are not allowed to access the channel to perform wireless frame transmission within the protection window. In some embodiments of the present application, the wireless communication between the AP and the STA is implemented by an asymmetric wireless communication mode, which means that the AMP operation element is used to indicate a first wireless transmission parameter of the uplink between the AP and the STA, the first operation element is used to indicate a second wireless transmission parameter of the downlink between the AP and the STA, or the first operation element is used to indicate the first wireless transmission parameter and the AMP operation element is used to indicate the second wireless transmission parameter. In some embodiments of the present application, if the asymmetric communication is supported, the transmission operation parameters of the uplink and the downlink can be indicated by the AMP operation element and the first operation element, respectively. In some embodiments of the present application, the uplink operation parameter is indicated by the AMP operation element. The downlink operation parameter is indicated by the first operation element, for example, the standard-defined wake-up receiver operation element (WUR operation element), high-throughput operation element (HT operation element), sub-1 GHz bandwidth operation element (S1G operation element), and the like, which are not limited herein. This embodiment does not need to modify the standard-defined operation element.

[0089] Method 2: Based on the operation element, an asymmetry operation information field (Asymmetry operation info) field is added to indicate the operation parameters of the AMP BSS:

[0090] Method 2-1: Based on the AMP operation element and the asymmetry operation information field for indication:

[0091] Figure 5B is a schematic diagram of an AMP operation element according to an embodiment of the present application. In some embodiments of the present application, as shown in Figure 5B, the AMP operation element includes one or more of the following fields: an Element ID field, used to indicate the ID of the AMP operation element, for distinguishing from other elements defined by IEEE 802.11; a Length field, used to indicate the number of octets of the AMP operation element, i.e., to indicate the field length information of the element; an Asymmetry operation info field, used to indicate the relevant information of the AMP BSS for asymmetric wireless communication operation, which can indicate the operation parameters of uplink and downlink; an AMP Operation Information field, used to indicate the operation information of the AMP BSS; a Modulation and Coding Scheme and Number of Spatial Stream Set (MCS and NSS Set) field, used to indicate the MCS (group) information supported by the AMP STAs (AP and non-AP) in the AMP BSS, which can be indicated by a list, a bitmap, an interval of Max MCS and min MCS, etc., which is not limited here.

[0092] In some embodiments of the application, the asymmetric operation information field includes, but is not limited to, one or more of the following subfields: an asymmetry supported subfield to indicate whether asymmetric wireless communication operation is supported, such as by 0 to indicate that asymmetric UL and DL operation is not supported, and 1 to indicate that asymmetric UL and DL operation is supported; an UL operation info presented subfield (optionally) to indicate whether the AMP operation information field and the MCS and NSS set field provide UL related parameter information; a DL operation info presented subfield (optionally) to indicate whether the AMP operation information field and the MCS and NSS set field provide DL related parameter information. In some embodiments of the application, when the asymmetry supported subfield is a first value, the AMP BSS does not support asymmetric UL and DL operation, and the AMP operation information subfield and the MCS and NSS set subfield are for symmetric communication related operation parameters. In some embodiments of the application, when the asymmetry supported subfield is a second value, the AMP BSS supports asymmetric UL and DL operation, and the UL operation info presented subfield and / or the DL operation info presented subfield are present. In some embodiments of the application, when the asymmetry supported subfield is the second value, the UL operation info presented subfield is the first value, and the DL operation info presented subfield is the second value, the AMP operation information subfield and the MCS and NSS set subfield are for asymmetric UL or DL parameters. When the asymmetry supported subfield, the UL operation info presented subfield, and the DL operation info presented subfield are all the second value, the AMP operation information subfield and the MCS and NSS set subfield indicate UL and DL operation parameters respectively, and both the UL and DL operation parameters are for symmetric communication operation parameters. The first value is, for example, 0 and the second value is, for example, 1.

[0093] In other words, only when the Asymmetry supported subfield is 1, the UL operation info presented subfield and the DL operation info presented subfield exist, for indicating whether the following related fields indicate the UL and DL respectively, such as when the Asymmetry supported subfield is 1, the UL operation info presented subfield is 1, and the DL operation info presented subfield is 0, the following AMP operation info subfield and the MCS and NSS set subfield indicate the related operation parameters for symmetric communication and the UL related operation parameters for asymmetric communication. When the Asymmetry supported subfield is 1, the UL operation info presented subfield is 1, and the DL operation info presented subfield is 1, the AMP operation info subfield and the MCS and NSS set subfield indicate the operation parameters for UL and DL respectively, and both can be used for the operation parameters for symmetric communication.

[0094] Method 2-2: Indication based on the first operation element combined with the asymmetric operation information field (i.e. the second operation element):

[0095] In some embodiments of the present application, the first operation element can refer to the operation element of the frame structure already existing in the existing standard, and the second operation element can refer to the modification of the operation element already existing in the standard, with the addition of the asymmetric operation information field, which is different from the frame structure of the existing HT operation element, S1G operation element, etc. In some embodiments of the present application, the second operation element includes the asymmetric operation information field, for indicating the uplink or downlink operation information of the AMP BSS for asymmetric wireless communication operation.

[0096] In some embodiments of the present application, based on the operation element already defined by IEEE 802.11, the uplink and downlink operation of the AMP STA and the AMP AP in the BSS supporting asymmetric communication is indicated respectively by combining the asymmetric operation information field, such as adding the asymmetric operation information field to the S1G operation element already defined by the standard to indicate the downlink operation parameters, and adding the asymmetric operation information field to the HT operation element already defined by the standard to indicate the uplink related operation parameters.

[0097] FIG. 5C is a schematic diagram of a first working element according to an embodiment of the present application. In some embodiments of the present application, as shown in FIG. 5C, the second working element, for example, indicates the AMP DL related parameters based on the S1G working element, and the second working element includes one or more of the following fields: an Element ID field, used to indicate the ID of the second working element; a Length field, used to indicate the number of octets of the second working element, i.e., to indicate the field length information of the element; an Asymmetry operation info field, used to indicate the related information of the SIG BSS for the asymmetric wireless communication operation, which can indicate the working parameters of the uplink and downlink; an S1G Operation Information field, used to indicate the working information of the S1G BSS; and a Basic S1G-MCS and NSS Set field, used to indicate the MCS (group) information supported by the AMP STA (AP and non-AP) in the S1G working information BSS, which can be indicated by a list, a bitmap, an interval of the maximum MCS (Max MCS) and minimum MCS (min MCS), etc., which is not limited here.

[0098] FIG. 5D is a schematic diagram of a second working element according to an embodiment of the present application. As shown in FIG. 5D, in some embodiments of the present application, the second working element, for example, indicates the AMP UL related parameters based on the HT working element, and the second working element includes one or more of the following fields: an Element ID field, used to indicate the ID of the second working element; a Length field, used to indicate the number of octets of the second working element, i.e., to indicate the field length information of the element; an Asymmetry operation info field, used to indicate the related information of the SIG BSS for the asymmetric wireless communication operation, which can indicate the working parameters of the uplink and downlink; a Channel Primary field, used to indicate the related information of the primary channel; an HT Operation Information field, used to indicate the working information of the HT BSS; and a Basic HT-MCS Set field, used to indicate the MCS (group) information supported by the AMP STA (AP and non-AP) in the HT working information BSS, which can be indicated by a list, a bitmap, an interval indicated by the maximum MCS (Max MCS) and the minimum MCS (min MCS), etc., which is not limited herein.

[0099] Among them, the Asymmetry operation info field can be defined as method 1, which respectively indicates the working parameters of the uplink and downlink. The downlink working parameters can also be indicated by the WUR working element.

[0100] Similarly, when the BSS supports the asymmetric communication operation, the operation element is not limited to the S1G working element and the HT working element, and the asymmetric communication operation of the uplink and downlink can also be indicated by adding the Asymmetry operation info field in the WUR working element, the HE working element, and the related working element, such as by the WUR working element, which is not described herein again.

[0101] In some embodiments of the application, the asymmetric operation information field includes, but is not limited to, one or more of the following subfields: an asymmetry supported subfield to indicate whether asymmetric wireless communication operation is supported, such as by 0 to indicate that asymmetric UL and DL operation is not supported, and 1 to indicate that asymmetric UL and DL operation is supported; an UL operation info presented subfield (optionally) to indicate whether the AMP operation information field and the MCS and NSS set field provide UL related parameter information; a DL operation info presented subfield (optionally) to indicate whether the AMP operation information field and the MCS and NSS set field provide DL related parameter information. In some embodiments of the application, when the asymmetry supported subfield is a first value, the AMP BSS does not support asymmetric UL and DL operation, and the AMP operation information subfield and the MCS and NSS set subfield are for symmetric communication related operation parameters. In some embodiments of the application, when the asymmetry supported subfield is a second value, the AMP BSS supports asymmetric UL and DL operation, and the UL operation info presented subfield and / or the DL operation info presented subfield are present. In some embodiments of the application, when the asymmetry supported subfield is the second value, the UL operation info presented subfield is the first value, and the DL operation info presented subfield is the second value, the AMP operation information subfield and the MCS and NSS set subfield are for asymmetric UL or DL parameters. When the asymmetry supported subfield, the UL operation info presented subfield, and the DL operation info presented subfield are all the second value, the AMP operation information subfield and the MCS and NSS set subfield indicate UL and DL operation parameters respectively, and both the UL and DL operation parameters are for symmetric communication operation parameters. The first value is, for example, 0 and the second value is, for example, 1.

[0102] In other words, only when the Asymmetry supported subfield is 1, the UL operation info presented subfield and the DL operation info presented subfield exist, indicating whether the following related fields indicate the UL and DL respectively, such as when the Asymmetry supported subfield is 1, the UL operation info presented subfield is 1, and the DL operation info presented subfield is 0, the following AMP operation info subfield and the MCS and NSS set subfield indicate the related operation parameters of symmetric communication and the UL related operation parameters of asymmetric communication. When the Asymmetry supported subfield is 1, the UL operation info presented subfield is 1, and the DL operation info presented subfield is 1, the AMP operation info subfield and the MCS and NSS set subfield indicate the operation parameters of the UL and DL respectively, and both can be used for the operation parameters of symmetric communication.

[0103] Technical effects of the first embodiment: define the indication method of the AMP BSS operation related parameters and the necessary indication information. Support the symmetric and asymmetric communication operation modes within the BSS. Include two methods of defining new operation elements and modifying legacy operation elements.

[0104] Second embodiment: device state / transmission mode management operation

[0105] In some embodiments of the application, the setting or switching the transmission mode of the STA comprises: the AP receiving the capability report of the STA, wherein the capability report of the STA is used to indicate whether the STA is a STA with negotiation capability and / or the time required for mode switching; and / or the high-capability transmission mode of the STA is initiated by the AP to switch; and / or when the STA is a STA without negotiation capability, the STA defaults to follow the indication of the AP to complete the transmission mode switching within the switching time; and / or when the STA is a STA with negotiation capability, the AP sends the control frame to the STA after receiving the control response frame sent by the STA, and the control response frame indicates the feedback information of the STA. In some embodiments of the application, the feedback information comprises one or more of the following information: the STA agrees to the indication of the AP to switch the mode; the STA agrees to switch to the high-capability transmission mode to negotiate to modify the transmission parameters; the STA agrees to switch to the high-capability transmission mode to negotiate to modify the configuration parameters of the wireless energy transmission link or the state of the wireless energy transmission link to support the STA to switch to the high-capability transmission mode; the STA does not agree to switch to the high-capability transmission mode and agrees to switch to the low-capability transmission mode. In some embodiments of the application, the time required for mode switching comprises: indicating the fixed time for mode switching; and / or indicating the time required for different mode switching; and / or indicating the time interval required for mode switching. In some embodiments of the application, the time interval required for mode switching comprises: the shortest time and the longest time required for mode switching.

[0106] In some embodiments of the application, the transmission modes of the STA include a high-capability transmission mode, a low-capability transmission mode, a listening mode, and / or a sleep mode, and the time required for switching between different modes includes the time required for switching between any two of the high-capability transmission mode, the low-capability transmission mode, the listening mode, and the sleep mode. In some embodiments of the application, the STA switches from the high-capability transmission mode to the low-capability transmission mode, the listening mode, or the sleep mode according to an indication of the AP, a negotiation initiated by the AP, a decision of the STA, and / or a state of wireless energy transfer. In some embodiments of the application, the AP receives a capability report of the STA, which indicates a series of fixed-value parameters of the STA itself, including data rate, bandwidth, MCS, number of spatial streams, and / or transmission power, as relevant operating parameters of the listening mode and / or the low-capability transmission mode. In some embodiments of the application, the AP receives a capability report of the STA, which indicates whether the STA itself supports the high-capability transmission mode and / or high-capability transmission parameters for the AP to indicate or negotiate, including the negotiable range of data rate, bandwidth, MCS, number of spatial streams, and / or transmission power.

[0107] In some embodiments of the application, the STA switches from the low-capability transmission mode, the listening mode, or the sleep mode to the high-capability transmission mode only when transmitting uplink data, and according to an indication of the AP and / or a negotiation initiated by the AP and successful negotiation. In some embodiments of the application, the STA switches from the high-capability transmission mode to the low-capability transmission mode, the listening mode, or the energy-saving mode when a transmission protection window for uplink data ends. In some embodiments of the application, the STA switches from the high-capability transmission mode to the low-capability transmission mode, the listening mode, or the energy-saving mode within a transmission protection window for uplink data when a transmission process for uplink data is completed, where the completion of the transmission process for uplink data means that the AP receives a data report frame of the STA, a more data field of the data report frame indicates a first value, and / or the AP sends a corresponding acknowledgement or block acknowledgement message to the STA after receiving the data report frame. The first value is, for example, 0. In some embodiments of the application, when wireless communication between the AP and the STA supports asymmetric wireless communication operation, the downlink transmission mode of the STA adopts the low-capability transmission mode, and the uplink transmission mode of the STA adopts the high-capability transmission mode.

[0108] Specifically, in some embodiments of the present application, for backscatter-only AMP device (AMP-only device) devices, whether close-range or long-range backscatter scheme, the AMP non-AP STA or AMP tag does not have an active transmitter, relies on the AMP AP or AMP reader for triggering, and wireless energy transfer can be completed directly by the reader or by an independent wireless energy transfer node. For backscatter AMP non-AP STA, the device state definition can refer to Table 2.

[0109] Table 2: Device state definition of backscatter AMP non-AP STA:

[0110] In some embodiments of the present application, the relevant device state management operations include:

[0111] The AMP STA switches between on / off device states to complete the response according to the link budget limited by wireless energy transfer and the triggering of the AMP AP, and in the on state, relies on the carrier signal to complete data reporting or response to other control management signaling.

[0112] Before performing data reading, the AMP AP should perform state query to determine whether the AMP STA successfully receives the RF wake-up signal and switches to the on state, and then performs subsequent other message interaction behavior.

[0113] In some embodiments of the present application, for the scene of wireless energy transfer node and reader integration, the state code is carried in the response information, and in the state query and state response process, the device state is indicated by the state code. In some embodiments of the present application, for the scene of wireless energy transfer node and reader separation, the state code is carried in the response information, which is used for device state indication. In some embodiments of the present application, for the scene of wireless energy transfer node and reader separation, the state code is carried in the configuration request frame and the configuration response frame, and the configuration scheduling of wireless energy transfer is indirectly indicated by indicating the target state of the AMP STA.

[0114] Specifically, in some embodiments of the present application, for devices with an active transmitter, they can switch between different transmission modes according to the indication of the AMP AP or their own decision or the state of wireless energy transfer, so as to achieve the balance between energy saving effect and data transmission capability. The transmission mode definition can refer to Table 3.

[0115] Table 3: Transmission mode definition of device with active transmitter:

[0116] The related transmission mode management operations include:

[0117] In some embodiments of the present application, when the AMP STA reports its capability to the AMP AP, it can indicate a series of fixed value parameters of itself, including data rate, bandwidth, MCS, number of spatial streams, transmit power, etc., which will be used as the related working parameters of the listening mode and the low capability transmission mode. In this case, switching from the high capability transmission mode to the low capability transmission mode or the listening mode does not need to be negotiated or indicated with the AP, i.e., the AMP STA does not need to indicate to the AMP AP that it has entered the energy saving state, and the control or management frame of the DL is transmitted by default using the fixed parameters indicated by the AMP STA.

[0118] In some embodiments of the present application, when the AMP STA reports its capability to the AMP AP, it can indicate whether it supports the high capability transmission mode and the high capability transmission parameters that can be indicated or negotiated by the AMP AP, including the negotiable range of parameters such as data rate, bandwidth, MCS, number of spatial streams, and transmit power. Switching from the low capability to the high capability needs to be indicated by the AP or initiated by the AP.

[0119] In some embodiments of the present application, the high capability transmission mode is only used at the time of the UL data frame, which means that when the transmission protection window for data reporting is terminated, the AMP STA does not need to remain in the high capability transmission mode regardless of whether the data transmission is completed, i.e., the AMP STA switches from the high capability transmission mode to the low capability transmission mode, the listening mode, or the doze mode.

[0120] In some embodiments of the present application, in the data reporting frame sent by the AMP STA to the AMP AP, the more data field is indicated as 0, and / or after the data reporting frame is sent, the corresponding ACK or block ACK message sent by the AMP AP is received, and regardless of whether the transmission protection window is ended, the high capability transmission state does not need to be maintained. That is, the AMP STA completes the data transmission process and can switch to the energy saving mode in advance within the protection window. In some embodiments of the present application, for the AMP STA supporting asymmetric transmission, the transmission mode can be directly bound with TX or RX, and the default downlink uses the low capability transmission to ensure reliability, and the uplink uses the high capability transmission with high rate or high throughput.

[0121] In some embodiments of the present application, for a multi-link device, such as an AMP non-AP STA MLD, it can implement separation of control link and data link, and since the AMP IoT rarely occurs in the scenario of data downlink, the control link can be in a default low-capability state for transmission or listening, and cross-link triggered data reporting can be implemented, and the data link has the capability of high-capability transmission. The transmission mode definition of the affiliated STA of the control link can refer to Table 4.

[0122] Table 4: Transmission mode definition of affiliated STA:

[0123] The device state definition of the affiliated STA of the data link can refer to Table 5.

[0124] Table 5: Device state definition of affiliated STA:

[0125] Similarly, in some embodiments of the present application, the relevant management operation includes:

[0126] The AMP MLD indicates the relevant capability and supported transmission mode or device state of its affiliated STA when reporting the capability. The control or management frame of the DL is transmitted by default with the relevant parameters of the low-capability or listening mode indicated by the AMP STA associated with the control link.

[0127] For the affiliated STA capable of supporting high-capability transmission, when reporting the capability, it indicates whether the uplink capability can be negotiated, and the relevant negotiable parameters. The negotiable parameters can be fixed parameters or variable parameters. For the relevant management control signaling such as trigger, ACK, Block ACK, and the like, sent by the AMP AP for data reporting, they are still sent and received through the control link, including the indication or request of the transmission parameters by the AMP AP, which needs to be downlink through the control link, and the data link only performs UL link transmission.

[0128] In some embodiments of the present application, other mode switching operations include:

[0129] The AMP STA indicates whether it has the capability of mode negotiation and the time required for mode switching during the capability reporting stage.

[0130] The high-capability transmission mode is initiated by the AMP AP, and the AMP STA without the capability of negotiation complies with the indication of the AMP AP by default and completes the mode switching within the switching time; the AMP STA with the capability of negotiation should send a control response frame to the AMP AP after receiving the control frame, and feedback is performed through the control response frame. The feedback information can include: agreeing with the indication of the AMP AP and performing mode switching; agreeing with the high-capability transmission mode transmission and negotiating to modify a certain transmission parameter; agreeing with the high-capability transmission mode transmission and negotiating to modify the configuration parameter of the wireless energy transmission link or the state of the wireless energy transmission link to support the AMP STA to accumulate enough energy to switch to the high-capability transmission mode; disagreeing with the switching to the high-capability transmission mode and negotiating to perform the low-capability transmission mode transmission.

[0131] For the time required for mode switching, the following methods are used to indicate the mode switching time: indicating a fixed mode switching time T; indicating a list of times required for different mode switching, such as the time required for switching from the low-capability transmission mode to the high-capability transmission mode T1, the time required for switching from the listening mode to the low-capability transmission mode T2, and the like; and indicating the time interval required for mode switching, such as indicating the shortest time and the longest time required for mode switching.

[0132] Technical effects of the second embodiment: defining the device states or transmission modes of various AMP STAs. Defining the related operation rules and behaviors for managing the device states and transmission modes on the wireless communication link. Defining the parameter information in the capability reporting stage.

In some embodiments of the present application, the state report of the wireless power transfer link and / or the configuration parameter report of the wireless power transfer link is used to query the state and / or the configuration parameter of the wireless power transfer link by the AP sending the control frame, the AP receiving the response frame sent by the wireless power transfer node, the response frame carrying the state report of the wireless power transfer link and / or the configuration parameter report of the wireless power transfer link; or the AP receiving the report frame sent by the wireless power transfer node, the report frame carrying the state report of the wireless power transfer link and / or the configuration parameter report of the wireless power transfer link.

[0136] In some embodiments of the present application, the wireless power transfer node receives the control frame sent by the AP, and / or the wireless power transfer node sends the response frame to the AP, the control frame and / or the response frame carrying the configuration information and / or the state information of the periodic or aperiodic wireless power transfer.

In some embodiments of the present application, the wireless power transfer node can decide to suspend and restart the wireless power transfer link according to its own transmission schedule, its own energy state, and the AMP wireless communication schedule broadcast by the AMP AP.

[0143] In some embodiments of the present application, the on and off switching of the wireless power transfer link is not allowed to be decided by the wireless power transfer node, and is realized by the following two ways: 1.

In some embodiments of the application, when the transmission mode of the STA is a listening mode, the AP sends the control frame to the STA to request the STA to switch to a high-capability transmission mode, and indicates the transmission parameters. In some embodiments of the application, when the current wireless power transfer power transmission efficiency is insufficient to support the high-capability transmission mode, the AP and the STA negotiate to keep the transmission mode in a low-capability transmission mode by receiving the response frame.

[0147] In some embodiments of the application, the AP sends the control frame to the STA again to request the STA to switch to a high-capability transmission mode, and receives the response frame to agree to the transmission mode switching.

In some embodiments of the application, the AP receives the wireless power transfer node agreeing to the modification of the configuration parameters of the wireless power transfer link. In some embodiments of the application, after the AP receives the wireless power transfer node agreeing to the modification of the configuration parameters of the wireless power transfer link, the AP initiates negotiation to the STA again, and sends the control frame to request the STA to switch to the high-capability mode. In some embodiments of the application, the AP receives the STA agreeing to the transmission mode switching.

After receiving the control frame, the AMP STA sends a response frame to disagree to switch to the high capability transmission mode and negotiate to keep the low capability transmission mode because the current wireless energy power transmission efficiency is not enough to support the high capability transmission mode.

[0150] In some embodiments of the present application, the AMP AP sends a control frame again to request to switch to the high capability transmission mode, the AMP STA sends a response frame to agree to the mode switching request and negotiate to adjust the wireless energy link configuration parameters to support the AMP STA to obtain higher energy to support the switching and keeping of the high capability transmission mode.

[0152] In some embodiments of the present application, after the AMP AP receives the agreement response of the wireless energy transmission node, the AMP AP initiates the negotiation to the AMP STA again, sends a control frame to request the AMP STA to switch to the high capability mode. The AMP STA detects the improvement of the wireless energy signal power density, agrees to the request of the AMP AP, sends a response frame, and switches to the high capability mode.

[0153] In some embodiments of the present application, the AMP AP sends a control frame to trigger the data reporting of the AMP STA, and the control frame indicates a protection window of the data reporting. The AMP STA performs the data reporting in the transmission resource allocated by the AMP AP, and switches to the low-capability mode after completing the transmission of the data reporting frame, and receives the ACK sent by the AMP AP. After receiving the ACK sent by the AMP AP, the AMP STA switches to the listening mode to save energy.

[0154] Technical effects of the fourth embodiment: The AMP AP requests the AMP STA to switch the transmission mode through the control frame, and triggers the data reporting of the AMP STA. The AMP STA negotiates the transmission mode through the response frame. The AMP STA requests the modification of the wireless power transmission configuration parameter based on the requirement of the wireless communication, and the AMP AP initiates the update of the wireless power transmission link configuration.

[0155] The fifth embodiment: The first solution: The AP indicates the transmission mode according to the wireless power transmission link configuration:

In some embodiments of the present application, the AP sends a first control frame to the STA, indicates the STA to switch to the high-capability transmission mode and the transmission parameter of the high-capability transmission mode through the first control frame, and allocates the transmission resource for the AMP STA. In some embodiments of the present application, the AP starts a timer after sending the first control frame, and by default, the STA completes the switching of the transmission mode within a second time, wherein the second time is greater than or equal to the first time.

[0157] In some embodiments of the present application, when the AP receives the data report of the STA in the protection window period, the transmission mode of the STA is the high-capability transmission mode, and before the expiration of the timer, when the AP sends an acknowledgement to the STA, the transmission mode of the STA is switched from the high-capability transmission mode to the listening mode. In some embodiments of the present application, the AP receives a request frame sent by the wireless energy transfer node, the request frame requests to update the current configuration parameters of the wireless energy transfer link and indicates the configuration parameters of the wireless energy transfer link suggested by the wireless energy transfer node. In some embodiments of the present application, the AP sends a response frame to the wireless energy transfer node, the response frame indicates the agreement of the configuration parameters of the wireless energy transfer link suggested by the wireless energy transfer node. In some embodiments of the present application, the AP sends a second control frame to the STA, the second control frame indicates that the STA is switched from the listening mode to the sleep mode.

[0158] FIG. 7 is a flowchart of the AP directly indicating the switching of the transmission mode according to an embodiment of the present application. In some embodiments of the present application, as shown in FIG. 7, an AMP AP and a wireless energy transfer node establish a wireless energy transfer management link, the wireless energy transfer link ID is 1, the configuration parameters of the wireless energy transfer are negotiated, and the wireless energy transfer node keeps the wireless energy transfer on. When the AMP STA performs capability reporting to the AMP AP, the AMP STA declares that it does not have the transmission mode negotiation capability as defined in the second embodiment, and the time required for the mode switching is T. The AMP AP sends a first control frame to the AMP STA, the first control frame indicates that the AMP STA is switched to the high-capability mode and the related transmission parameters of the high-capability mode, and the AMP AP allocates transmission resources for the AMP STA. Different from the fifth embodiment, the AMP AP does not need to wait for the AMP STA to send a control response frame, starts a timer after sending the control frame, and by default, the AMP STA completes the mode switching within T0 time, T0≥T (for example, T0=T+SIFS).

[0159] In some embodiments of the present application, after the mode switching is completed, the AMP STA directly performs data reporting in the high-capability mode in the protection window period and sends a data reporting frame. The AMP AP receives the data reporting frame sent by the AMP STA before the expiration of the timer and feeds back an ACK. After receiving the ACK, the AMP STA ends the high-capability transmission mode and switches to the listening mode.

[0160] In some embodiments of the present application, the wireless power transfer node sends a request frame to the AMP AP, as defined in the second embodiment, requesting to update the transmission parameters configured for the current wireless power transfer link, and indicates the parameters it requests to modify, such as requesting to reduce the transmission power of the wireless power transfer, the AMP AP receives the request frame, and sends a response frame to the wireless power transfer node, indicating that it agrees to its request to update the wireless power transfer parameters. The wireless power transfer node receives the response frame of the AMP AP, and modifies the wireless power transfer transmission parameters.

[0161] In some embodiments of the present application, after the AMP AP agrees to the request of the wireless power transfer node to reduce the transmission power, based on the configuration modification of the wireless power transfer link, the AMP AP sends a second control frame to the AMP STA, indicating the AMP STA to switch to a doze mode to save energy, the AMP STA receives the second control frame, and switches from the listening mode to the doze mode.

[0163] Sixth embodiment: first solution: according to the state of the wireless power transfer link, the STA switches the transmission mode by itself:

[0164] In some embodiments of the present application, based on the parameters and / or state of the wireless power transfer configuration between the AP or the STA and the wireless power transfer node, or based on the wireless power transfer link established between the AP and the wireless power transfer node, the AP manages the wireless communication link, including: based on the schedule, state, and / or parameters of the wireless power transfer link, the switching of the transmission mode is decided by the STA, the AP queries the schedule, state, and / or parameters of the wireless power transfer link from the wireless power transfer node, and the AP sends frame interaction to the STA according to the schedule, state, and / or parameters of the wireless power transfer link. In some embodiments of the present application, the switching of the transmission mode includes switching from a high-capability transmission mode to a low-capability transmission mode, switching from a listening mode to a power saving mode, switching from a power saving mode to a listening mode, and / or switching from a listening mode to a low-capability transmission mode.

[0165] FIG. 8 is a flowchart of a process for the STA to determine to switch the transmission mode according to an embodiment of the present application. In some embodiments of the present application, as shown in FIG. 8, the AMP STA can switch from the high capability state to the low capability state according to the power condition of the device, the charging link configuration, the UL or DL waiting transmission buffer, and other conditions. The AMP AP device does not send data downstream to the AMP STA device, but only sends management frames or control frames downstream. The default DL is in the low capability state. Therefore, when the AMP STA switches from the high capability state to the low capability state, the AMP AP does not need to be notified.

[0166] As shown in FIG. 8, in some embodiments of the present application, the wireless energy transfer management link is established between the AMP AP and the wireless energy transfer node. The wireless energy transfer link ID is 1. The wireless energy transfer configuration parameters are negotiated. The wireless energy transfer node keeps the wireless energy transfer on. When the wireless energy transfer node determines to suspend the wireless energy transfer due to insufficient power or a wireless communication task, the wireless energy transfer node can determine to suspend the wireless energy transfer by itself. At this time, the environmental energy density received by the AMP STA decreases significantly, and the AMP STA can determine to switch from the listening mode to the doze mode by itself. The AMP AP sends the control frame to the AMP STA in the doze mode. The feedback frame is not received before the timer expires.

[0167] In some embodiments of the present application, the AMP AP sends the wireless energy transfer state query frame to the wireless energy transfer node, and receives the state report frame of the wireless energy transfer node. As defined in the second embodiment, the report frame indicates that the wireless energy transfer link state is suspended, and indicates the suspension schedule, such as the suspension duration, the restart time, and the like.

[0168] In some embodiments of the present application, the wireless energy transfer link ends the suspended state, restarts the wireless energy transfer, the AMP STA accumulates energy from the environment, and switches from the doze mode to the listening mode again. The AMP AP receives the state report frame sent by the wireless energy transfer node, and sends the control frame to the AMP STA again after the wireless energy transfer link state is switched to the on state. The AMP STA switches to the low capability mode and sends the control response frame to the AMP AP.

[0169] The seventh embodiment has the following technical effects: the AMP STA determines to switch the transmission mode by itself based on the link state of the wireless energy transfer link; the AMP AP queries the wireless energy transfer link state from the wireless energy transfer node; the wireless energy transfer node reports the wireless energy transfer link state and the schedule information to the AMP AP; and the AMP AP initiates the frame interaction with the AMP STA according to the wireless energy transfer link state and the schedule.

[0170] The seventh embodiment: first solution: schedule d coordination management

[0171] In some embodiments of the application, based on the transmission requirement of the wireless communication link between the AP and the STA, the AP manages the wireless energy transfer link based on the indication or negotiation of the AP or the STA to the wireless energy transfer node includes: the AP performs coordinated management of wireless energy transfer and AMP communication, the scheduling, state, and / or parameters of the wireless energy transfer link are decided by the wireless energy transfer node based on the transmission requirement of the wireless communication link, and the switching of the transmission mode is decided by the STA based on the transmission requirement of the wireless communication link. In some embodiments of the application, the AP allocates periodic transmission resources to the STA, the AP broadcasts the AMP target wake-up time (TWT) parameters to the wireless energy transfer node through a control frame or a beacon frame, the AP broadcasts a switching time indicating that the STA switches from a sleep mode to a high-capability transmission mode, and non-AMP STAs are not allowed to access the channel within the TWT window duration broadcast by the AP. In some embodiments of the application, the TWT parameters include TWT window duration, TWT interval, and / or non-trigger-based TWT type.

[0172] In some embodiments of the application, based on the AMP TWT parameters and / or the time required for the STA to switch modes, the wireless energy transfer node decides the state of the wireless communication link, and the wireless energy transfer transmission is turned on for a first time period before the start time of the TWT window duration to complete the switching of the STA mode. In some embodiments of the application, the first time period is greater than or equal to the switching time of the STA from the sleep mode to the high-capability transmission mode, and the duration of the wireless energy transfer transmission is equal to the first time period plus the TWT window duration. In some embodiments of the application, based on the TWT parameters, the wireless energy transfer transmission is periodically turned on or turned off to achieve coordinated management of wireless energy transfer and AMP communication.

[0173] FIG. 9 is a flow diagram of the cooperative management of the scheduling of the wireless power transfer and the AMP wireless transmission according to an embodiment of the present application. In some embodiments of the present application, as shown in FIG. 9, the wireless power management link is established between the AMP AP and the wireless power transfer node, the wireless power link ID is 1, the wireless power configuration parameters are negotiated, and the wireless power transfer node keeps the wireless power on. The AMP AP allocates the periodic transmission resource for the AMP STA, broadcasts the AMP TWT parameters through the beacon frame, the broadcast TWT parameters include the TWT window duration, the TWT interval, the non-TB TWT type and other related parameters, broadcasts the switching time T indicating the switching of the AMP STA from the doze mode to the high-capability transmission mode, and the non-AMP STA is not allowed to access the channel in the TWT window duration broadcasted by the AMP AP, thereby avoiding the need to send the trigger frame indicating the protection window for the AMP STA every time for the periodic data reporting. Note that the TWT parameters broadcasted through the beacon frame are taken as an example, and the TWT parameters can also be transmitted through the control frame. The protection window can be the transmission opportunity (TXOP), the service period or other standard-defined related transmission protection period. In some embodiments of the present application, the control frame and the control response frame can be the RTS frame, the CTS frame, the MU-RTS frame, the CTS frame, the trigger frame, the cts-to-self frame, the trigger frame, the ack frame, the trigger frame, the PS-Poll frame, the trigger frame, the data report frame and other traditional control or data frames, or the new request frame and response frame defined for the AMP IoT. The frame name, the flow name, the mechanism name and the field name in the embodiments of the present application are not unique.

[0174] In some embodiments of the present application, the wireless power transfer node receives the broadcast TWT parameters carried by the beacon frame and the time required for the mode switching of the AMP STA, decides the state of the wireless power link according to the parameters, turns on the wireless power transfer before the start time of the TWT window duration by T1 period of time, ensures the completion of the mode switching of the AMP STA, i.e., T1≥T, the on duration of the wireless power transfer is T0=T1+TWT window duration, and the wireless power is turned off after T0.

[0175] According to the TWT interval and other information broadcast by the AMP AP, the AMP STA enters a doze mode or a high-capability transmission mode periodically according to the TWT parameters broadcast by the AMP AP, switches to the high-capability mode by itself in the TWT window duration allocated by the AMP AP to complete data reporting, and returns to the doze mode after receiving the ACK sent by the AMP AP. The wireless power transfer node correspondingly periodically turns on or turns off the wireless power transfer, thereby realizing the management of scheduling wireless power transfer and AMP wireless communication.

[0176] The embodiment takes the broadcast TWT of the AMP AP and the AMP STA as an example, and the scenario of scheduling d also includes periodic beacon frame reception, periodic trigger frame or polling frame response, and the like, and the method is similar, which will not be described here.

[0177] The seventh embodiment has the technical effect that the AMP AP performs scheduling wireless power transfer and communication cooperative management; the wireless power transfer node decides the wireless power transfer link state by itself according to the scheduling communication demand; and the AMP STA decides the transmission mode by itself according to the scheduling communication demand.

The wireless communication link is based on the asymmetric communication capability of the AMP STA within the BSS and is completed on the downlink control frame or the uplink data frame of different frequency channels. When the wireless power transfer parameters and the wireless power transfer scheduling are not negotiated with the wireless power transfer node, the wireless power transfer node does not send the wireless charging signal, and the AMP STA enters the doze mode. The AMP AP sends the downlink control frame to the AMP STA, and does not receive the response frame.

[0181] In some embodiments of the present application, the AMP AP sends a control frame to the wireless energy transfer node to query the wireless energy transfer state, and the wireless energy transfer node sends a response frame to indicate that the wireless energy transfer link state is off.

After receiving a response agreement message from the wireless energy transfer node, the AMP AP MLD simultaneously sends a control frame to STA1 of the AMP non-AP MLD through AP3 via the control link, and requests AMP STA2 to perform data reporting. Similarly, the transmission parameters related to AMP STA2 can be indicated in the control frame.

[0189] The AMP non-AP MLD detects the wireless energy transmission signal, starts to accumulate energy, and starts STA2 after receiving the control frame and accumulating enough energy, and sends a response frame to the AMP AP3 through STA1, indicating that STA2 has switched to a high-capability mode based on the indicated transmission parameters. The AMP AP3 receives the response frame, sends a data reporting trigger frame to STA1, and allocates data reporting transmission resources to it. After STA1 receives the data reporting trigger frame, STA2 sends a data reporting frame through the data link established with AP2 according to the transmission resources allocated by the AMP AP MLD. After STA1 successfully receives the ACK sent by the AMP AP3, STA1 switches back to the listening mode, and STA2 switches to the doze mode, thereby maintaining the energy saving of the AMP non-AP MLD.

[0202] Twelfth embodiment: second solution: AMP non-AP MLD as wireless power transfer node and relay node

[0203] In some embodiments of the present application, the AP is an AP multi-link device MLD, the wireless power transfer node is a first STA of a first AMP non-access point multi-link device non-AP MLD, the STA is a second STA of a second AMP non-AP MLD, the AP performs management of the wireless communication link based on parameters and / or states of a wireless power transfer configuration between the AP or the STA and the wireless power transfer node, or based on the wireless power transfer link established between the AP and the wireless power transfer node; and / or the AP performs management of the wireless power transfer link based on a manner indicated or negotiated by the AP or the STA to the wireless power transfer node based on transmission requirements of the wireless communication link between the AP and the STA, including: a first AP of the AP MLD establishes a wireless communication link with the first AMP non-AP MLD, a second AP of the AP MLD establishes a wireless power transfer management link with the wireless power transfer node of the first AMP non-AP MLD, and the wireless power transfer and AMP communication are collaboratively managed through the first AMP non-AP MLD as a relay node.

[0204] In some embodiments of the present application, a data link is established between the first AMP non-AP MLD and the second AMP non-AP MLD, and a control link is established between the first AMP non-AP MLD and the second AMP non-AP MLD. In some embodiments of the present application, the AP MLD sends management and control messages to the relay node through the wireless communication link, and forwards the management and control messages to the second AMP non-AP MLD through the control link by the relay node, and the AP MLD receives data messages sent by the second AMP non-AP MLD forwarded by the relay node through the wireless communication link.

In some embodiments of the present application, as shown in Figure 14, for a non-AMP AP MLD, the data reporting trigger of the AMP non-AP MLD can be completed by the AMP non-AP MLD as a relay node. The wireless power transfer configuration between AP2 and the wireless power transfer node will not be repeated. As AP1 and AP2 of the AP MLD support 5GHz and 2.4GHz communication respectively, but cannot support S1GHz communication, the relay device AMP non-AP MLD1 and the target communication device AMP non-AP MLD2 establish a control link on the S1G frequency band and a data link on the 2.4GHz frequency band. AP1 sends a control frame to the relay node STA1-2 to request data reporting. The relay node can forward the control frame from STA1-3 to the target AMP non-AP MLD2 through the S1G frequency band control link. After receiving the data reporting of STA2-2, the relay node STA1-2 further reports the data to AP1, realizing that through the relay node, the non-AMP MLD device can also manage the wireless power transfer node and the wireless communication of the AMP.

[0206] Technical effect of the twelfth embodiment: through the relay node, assist the non-AMP AP to manage the AMP wireless power transfer and the AMP wireless communication.

[0207] Thirteenth embodiment: third solution: control and data reporting of close-range backscatter

[0208] In some embodiments of the application, the AP is a backscatter AMP AP, the STA is a backscatter AMP STA, and the wireless energy transfer node is integrated with the AP. In some embodiments of the application, the AP communicates with the STA in a point-to-point manner, and the control of the AP over the STA includes wake-up operation, state confirmation operation, and / or data reading operation. In some embodiments of the application, in the wake-up operation, the STA is woken up by the wireless energy signal on the wireless energy transfer link, and the STA switches from an off state to an on state. In some embodiments of the application, in the state confirmation operation, the STA remains in the on state, the AP sends control or management signaling and a carrier signal, and the AP receives response information backscattered by the STA through the carrier signal to confirm the state of the STA. In some embodiments of the application, in the data reading operation, the STA remains in the on state, the AP sends a control frame to initiate a data reading process after receiving the response information of the STA, and keeps transmitting the carrier signal after the control signaling, and the AP receives data information backscattered by the STA through the carrier signal. In some embodiments of the application, if the AP does not receive the backscattered response information of the STA or the backscattered data information of the STA, the AP re-performs the wake-up operation, the state confirmation operation, and / or the data reading operation. In some embodiments of the application, when the AP stops transmitting the carrier signal or the wireless energy signal, the STA switches from the on state to the off state.

[0209] FIG. 15 is a flow diagram of a close-range backscatter control and data reporting process according to an embodiment of the application. In some embodiments of the application, as shown in FIG. 15, an AMP STA or an AMP tag relies on a reader for data reading when it does not have an active transmitter. In a close-range backscatter scenario, the reader and the AMP tag communicate in a point-to-point manner, and the control of the AMP reader over the AMP tag mainly includes wake-up, state confirmation, and data reading operations. In the wake-up operation, the AMP tag completes the switching of the device state from off to on, and the wireless energy signal transmitted by the reader is used for waking up the AMP tag. In the state confirmation and data reading operations, the AMP tag remains in the on state. When the AMP reader stops transmitting the RF signal / carrier signal, the AMP tag remains in the off state.

[0210] In some embodiments of the present application, the reader sends an RF signal to wake up the AMP tag, and the AMP tag enters an on state from an off state. The AMP AP / reader transmits control or management signaling in the RF signal immediately after the wake-up signal and keeps transmitting the carrier signal to confirm the state of the AMP tag. After receiving the control or management signaling, the AMP tag modulates response information to the AMP reader through the carrier signal sent by the reader, thereby confirming to the AMP reader that it has entered the on state and received a request for data reading.

[0211] In some embodiments of the present application, after the AMP reader receives the response information of the AMP tag, it confirms that the AMP tag has been normally turned on, sends a control frame to initiate a data reading process, and keeps transmitting the carrier signal after the control signaling. The AMP tag modulates the collected data to the AMP reader through the carrier signal. The AMP reader receives the backscattered data information without sending any ACK signal to the AMP tag, and only needs to stop transmitting the RF signal. The AMP tag will return to the off state from the on state.

[0212] In some embodiments of the present application, if the current data reading is not successful, such as the AMP reader does not receive the response information of the AMP tag, cannot confirm the state of the device, or does not receive the data information or receives incomplete data information, etc., the continuous signal of wake-up-state confirmation-data reading needs to be sent again.

[0213] The technical effect of the thirteenth embodiment is to define the management signal sequence and state switching operation in the near-range backscattering communication process of the AMP reader and the AMP tag.

[0214] The fourteenth embodiment: the third solution: control and data reporting of long-range backscattering

[0215] In some embodiments of the present application, the AP is a backscatter AMP AP, the STA is a backscatter AMP STA, and the wireless energy transfer node is separate from the AP. In some embodiments of the present application, when the wireless energy transfer node is separate from the AP and the STA, the AP configures the wireless energy transfer link by sending a configuration request frame to the wireless energy transfer node, and the AP receives a configuration response frame from the wireless energy transfer node. In some embodiments of the present application, a first control frame sent by the AP indicates a first guard window, and a second control frame sent by the AP indicates a second guard window, the first guard window is used to trigger responses from all AMP STAs within the transmission range, and the second guard window is used to indicate a specific AMP STA to report data and to allocate transmission resources to the specific AMP STA. In the second guard window, an AMP STA that is not allocated transmission resources will directly enter an off state even if it receives a broadcast carrier signal.

[0216] FIG. 16 is a flowchart of control and data reporting for medium- and long-range backscatter according to an embodiment of the present application. In some embodiments of the present application, as shown in FIG. 16, when the wireless energy transfer node is separate from the AMP reader / AP, the AMP AP can configure the wireless energy transfer node by sending a configuration request frame to the wireless energy transfer node, and the AMP wireless energy transfer node can respond to the configuration request by sending a configuration response frame. The configuration of the wireless energy transfer node is completed through the interaction of the configuration request frame and the configuration response frame. As described in the second embodiment, the configuration can indirectly indicate the schedule of the wireless energy transfer by indicating the device state of the target AMP tag or STA.

[0217] The wireless energy transfer node sends a wake-up and energy charging signal according to the configuration of the AMP AP or reader. In this case, the transmission distance of the backscatter is mainly limited by the link budget of the wireless energy transfer. Unlike the near-range backscatter scenario, the wireless energy transfer node can support medium- and long-range backscatter communication when it is separate from the AMP AP or reader. However, when the transmission range is increased, the reader will trigger responses from multiple AMP STAs / tags at one time, which will also affect legacy STAs within the range. Therefore, the control frame of the reader needs to indicate a guard window. As shown in FIG. 16, the first guard window is used to trigger responses from all AMP STAs within the transmission range, and legacy STAs are not allowed to access the channel during this period. The second guard window is used to indicate a specific AMP STA / tag to report data and to allocate transmission resources to the specific AMP STA / tag. During this period, an AMP STA / tag that is not allocated transmission resources will directly enter an off state and will not respond to the control frame even if it receives a broadcast carrier signal.

[0218] The technical effect of the fourteenth embodiment is that the reader manages the wireless energy transfer node in the case of separation of the AMP reader and the wireless energy transfer node, and defines the management signal sequence and state switching operation in the backscattering communication process between the reader and the plurality of AMP tags.

[0219] In summary, the embodiments of the present application provide system capability support, and design a cooperative management and control mechanism for the AMP IoT wireless communication link and the wireless energy transfer link, so as to manage and control the wireless energy transfer link based on the data transmission demand of the wireless communication link, support the AMP STA to have sufficient energy consumption to complete the wireless frame interaction, manage the interference of the wireless energy transfer link to the wireless communication link, improve the reliability of the AMP IoT, manage the transmission mode and scheduling of the wireless communication link based on the state and configuration of the wireless energy transfer link in real time, and realize effective energy saving of the energy-sensitive device. The designed cooperative management and control mechanism is applicable to AMP STAs with different device capabilities, including AMP-only devices and AMP-assisted devices, supports direct management of the AMP AP, self-decision of the AMP STA / wireless energy transfer node, and negotiation decision of the AMP STA, wireless energy transfer node, and AMP AP. The separation of control signaling and data signaling is supported, hybrid link load distribution is realized, energy saving is realized while ensuring HDR / high-throughput data transmission. The embodiments of the present application provide new function design, and introduce related management functions such as query, report, suspension, and restart of the wireless energy transfer link.
