Obviously, the embodiments described are part of the embodiments of this application, not all of the embodiments. With respect to the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0037] Please refer to Figure 1, which shows a schematic diagram of a wireless communication system provided by an embodiment of the present application. As shown in Figure 1, the wireless communication system may include: an access point (AP) and a station (STA).
[0038] In some scenarios, an AP can be referred to as an AP STA, meaning that in a sense, an AP is also a type of STA. In some scenarios, a STA can be referred to as a non-AP STA.
[0039] In some embodiments, STAs may include AP STAs and non-AP STAs. Communication in a communication system may be between an AP and a non-AP STA, between a non-AP STA and a non-AP STA, or between a STA and a peer STA. A peer STA may refer to a device that communicates with a STA. For example, a peer STA may be an AP or a non-AP STA.
[0040] An AP acts as a bridge between wired and wireless networks, connecting wireless network clients together and then connecting the wireless network to the Ethernet. An AP can be a terminal device (such as a mobile phone) or a network device (such as a router) equipped with a Wireless Fidelity (Wi-Fi) chip.
[0041] It should be understood that the role of STA in the communication system is not absolute. For example, in some scenarios, when a mobile phone is connected to a router, the mobile phone is a non-AP STA. When the mobile phone serves as a hotspot for other mobile phones, the mobile phone plays the role of AP.
[0042] APs and non-AP STAs can be devices used in the Internet of Vehicles, IoT nodes and sensors in the Internet of Things (IoT), smart cameras, smart remote controls, smart water and electricity meters in smart homes, and sensors in smart cities.

[0047] There are one or more links between the station and the access point. In some embodiments, the station and the access point support multi-band communication. For example, communication is performed simultaneously on the 2.4 GHz, 5 GHz, 6 GHz, 45 GHz, and 60 GHz frequency bands, or communication is performed simultaneously on different channels of the same frequency band (or different frequency bands), thereby improving the communication throughput and / or reliability between devices. Such a device is generally referred to as a multi-band device, or a multi-link device (MLD), sometimes also referred to as a multi-link entity or a multi-band entity. A multi-link device can be an access point device or a station device. If the multi-link device is an access point device, the multi-link device includes one or more APs; if the multi-link device is a station device, the multi-link device includes one or more non-AP STAs.
[0048] A multi-link device including one or more APs may be referred to as an Access Point Multi-Link Device (AP MLD), and a multi-link device including one or more non-AP STAs may be referred to as a Non-Access Point Multi-Link Device (non-AP MLD).
[0049] In an embodiment of the present application, the AP may include multiple APs, the Non-AP may include multiple STAs, multiple links may be formed between the APs in the AP and the STAs in the Non-AP, and data communication may be performed between the APs in the AP and the corresponding STAs in the Non-AP through the corresponding links.

[0051] Optionally, both the station and the access point support the IEEE 802.11 standard.
[0052] In some embodiments, the communication system in the embodiments of the present application can be applied to a carrier aggregation (CA) scenario, a dual connectivity (DC) scenario, an independent (SA) networking scenario, or a non-standalone (NSA) networking scenario.
[0053] In some embodiments, the communication system in the embodiments of the present application can be applied to an unlicensed spectrum, where the unlicensed spectrum can also be considered as a shared spectrum; or, the communication system in the embodiments of the present application can also be applied to an authorized spectrum, where the authorized spectrum can also be considered as an unshared spectrum.

[0055] It should be understood that the terms "system" and "network" are often used interchangeably herein. The term "and / or" is simply a description of an association between related objects, indicating that three possible relationships exist. For example, "A and / or B" can represent: A exists alone, A and B exist simultaneously, or B exists alone. Furthermore, the character " / " generally indicates that the related objects are in an "or" relationship.
[0056] The terms used in the embodiments of this application are intended only to explain the specific embodiments of this application and are not intended to limit this application. The terms "first," "second," "third," and "fourth," etc. in the specification and claims of this application and the accompanying drawings are used to distinguish different objects, not to describe a specific order. In addition, the terms "including" and "having," and any variations thereof, are intended to cover non-exclusive inclusions.
[0057] It should be understood that the "indication" mentioned in the embodiments of this application can be a direct indication, an indirect indication, or an indication of an association. For example, "A indicates B" can mean that A directly indicates B, for example, B can be obtained through A; it can also mean that A indirectly indicates B, for example, A indicates C, and B can be obtained through C; it can also mean that there is an association between A and B.
[0058] In the description of the embodiments of the present application, the term "corresponding" may indicate a direct or indirect correspondence between the two, or an association relationship between the two, or a relationship between indication and being indicated, configuration and being configured, etc.
[0059] In the embodiments of the present application, "pre-definition" or "pre-configuration" may be implemented by pre-storing corresponding codes, tables, or other methods that can be used to indicate relevant information in a device (e.g., a terminal device and a network device). The present application does not limit the specific implementation method. For example, pre-definition may refer to information defined in a protocol.
[0060] In the embodiments of the present application, the “protocol” may refer to a standard protocol in the communications field, for example, it may be an evolution of an existing LTE protocol, NR protocol, Wi-Fi protocol, or a protocol related to other communication systems. The present application does not limit the protocol type.
[0061] In order to facilitate a better understanding of the embodiments of the present application, the positioning related to the present application is explained.
[0062] Positioning methods based on timing, angle, and carrier phase have long been used in Wi-Fi, 4G, 5G, and GNSS networks. Due to very limited power and processing capabilities, AMP devices are unable to transmit broadband positioning reference signals (PRS), so timing-based positioning methods such as Observed Time Difference of Arrival (OTDOA) cannot achieve satisfactory positioning accuracy. For the same reason, angle-based positioning is also not applicable because AMP devices can neither accurately measure the angle of the incoming signal nor send / reflect relatively directional signals.
[0063] In order to facilitate a better understanding of the embodiments of the present application, the AMP device related to the present application is described.
[0064] AMP devices can harvest energy from a variety of sources, including radio frequency (RF), solar energy, and thermal energy. RF is the most controllable of all energy sources. For RF energy harvesting, narrow-bandwidth S1G signals are particularly well-suited for AMP devices due to their favorable propagation characteristics.
[0065] It's important to note that AMP devices are also referred to as ambient power enabled IoT devices, or Ambient IoT devices for short. Specifically, an Ambient IoT device refers to an IoT device that uses various ambient energies, such as radio frequency energy, light energy, solar energy, thermal energy, and mechanical energy. Ambient IoT devices can have no energy storage capability or very limited energy storage capacity (such as using capacitors with a capacity of tens of microfarads).
[0066] In some embodiments, the Ambient IoT device can be used in at least the following four scenarios:
[0067] Object recognition, such as logistics, production line product management, and supply chain management;
[0068] Environmental monitoring, such as temperature, humidity, and harmful gas monitoring of working environment and natural environment;
[0069] Positioning, such as indoor positioning, intelligent object search, and production line item positioning;
[0070] Intelligent control, such as intelligent control of various electrical appliances in smart homes (turning on and off air conditioners, adjusting temperature), and intelligent control of various facilities in agricultural greenhouses (automatic irrigation and fertilization).
[0071] In order to facilitate a better understanding of the embodiments of the present application, the problems solved by the present application are explained.
[0072] Considering the capabilities and power consumption limitations of AMP devices, how to locate AMP devices is a problem that needs to be solved.
[0073] Based on the above problems, this application proposes a solution for AMP device positioning and a joint signal design for wireless charging and positioning. The AMP device can generate a first signal and a second signal with an associated relationship based on at least one received target signal, obtain energy through the first signal, and perform positioning based on the second signal, thereby reducing the signaling overhead required for AMP device positioning and improving system efficiency.
[0074] Specifically, narrow-bandwidth S1G signals are more suitable for energy harvesting in AMP devices due to their good propagation characteristics. Furthermore, narrow-bandwidth S1G signals can also be used for phase-based positioning. In other words, to achieve a reasonable wireless charging distance, low-frequency signals such as S1G are more suitable, and the same signal can be used for both energy harvesting and phase-based positioning.
[0075] To facilitate understanding of the technical solutions of the embodiments of the present application, the technical solutions of the present application are described in detail below through specific embodiments. The following related technologies can be combined with the technical solutions of the embodiments of the present application as optional solutions, and they all fall within the scope of protection of the embodiments of the present application. The embodiments of the present application include at least part of the following contents.
[0076] FIG2 is a schematic flowchart of a wireless communication method 200 according to an embodiment of the present application. As shown in FIG2 , the wireless communication method 200 may include at least part of the following contents:
[0077] S210, the first device sends at least one target signal to the AMP device;
[0078] S220: The AMP device receives at least one target signal sent by the first device, wherein the at least one target signal is used to generate a first signal and a second signal having an associated relationship;
[0079] S230: The AMP device obtains energy through the first signal and performs positioning according to the second signal.
[0080] In an embodiment of the present application, the AMP device can generate a first signal and a second signal with an associated relationship based on at least one received target signal, obtain energy through the first signal, and perform positioning based on the second signal, thereby reducing the signaling overhead required for positioning of the AMP device and improving system efficiency.
[0081] In some embodiments, the at least one target signal is a narrow-bandwidth S1G signal. Of course, the at least one target signal may also be other signals or other narrow-bandwidth signals, and this is not limited in the present embodiment. Specifically, the narrow-bandwidth S1G signal, due to its excellent propagation characteristics, is more suitable for AMP devices to perform energy harvesting and phase-based positioning.
[0082] It should be noted that the communication signal reception sensitivity and RF radio energy harvesting sensitivity are significantly different. For example, on WLAN, the Received Signal Strength Indication (RSSI) ranges from -20dBm (very close to the AP) to -95dBm (far away from the AP). Assuming a 10dBm margin to account for the inevitable RSSI fluctuations in the link budget, WLAN devices (such as WLAN devices in 802.11b / g) can maintain a wireless connection for signals greater than -84dBm. However, the energy harvesting sensitivity is only up to -35dBm. The 49dBm difference means that the wireless charging distance is much shorter than the communication distance.
[0083] AMP devices represent a significant market opportunity in many scenarios, such as smart homes, smart manufacturing, and logistics / warehouses. Due to their ultra-low cost and maintenance-free nature, AMP devices have opened up a whole new market. The technical solution of this application can be used when cost-effective, maintenance-free, and highly accurate AMP device positioning is required. The embodiments of this application provide a technology / process that can be applied to an AMP device-based positioning system with radio frequency energy harvesting.
[0084] In the embodiments of this application, a new type of node, a wireless charging node (WCN), is designed and deployed primarily for transmitting wireless charging signals. The WCN can charge AMP devices that are not wirelessly charged within the communication coverage area. Specifically, the WCN mainly transmits wireless charging signals, which can significantly reduce the complexity and cost of charging AMP devices.
[0085] In some embodiments, the deployment density of wireless charging nodes (WCNs) should be higher than that of normal communication nodes (such as access points). As shown in Figure 3, all AMP devices are within the communication coverage area, but only AMP 1 and AMP 2 are within the wireless charging coverage area of the AP. For AMP 3 and AMP 4, WCN 1 and WCN 2 are deployed, respectively, primarily for wireless charging. Specifically, narrow-bandwidth S1G signals can be suitable for wireless charging and can also be used for phase-based positioning to improve efficiency and reduce signaling overhead. For example, AMP 3 can receive communication signals from the AP and wireless charging signals from WCN 1, and AMP 4 can receive communication signals from the AP and wireless charging signals from WCN 2. Optionally, the at least one target signal can be sent by either the AP or the WCN. If the wireless charging signal can also be used for positioning, the AMP devices can receive more positioning signals, and positioning accuracy can be improved. Because the complexity and cost requirements of the WCN are minimal, data processing modules such as modulation / demodulation and encoding / decoding are not required.
[0086] In some embodiments, the first device is one of the following: a WCN, an access point (AP), a station (STA), a transmission reception point (TRP), a base station, or a terminal device. Optionally, when the first device is a device other than a WCN, the location of the first device is known, and the transmit power and stored energy of the first device meet preset conditions. Specifically, for example, the preset conditions are determined by negotiation between the first device and the AMP device, or the preset conditions are determined by the first device.
[0087] In some embodiments, the first device is a WCN; specifically, the network device associated with the AMP device has obtained the location information of the WCN before the WCN sends the at least one target signal; and / or, the relevant configuration of the WCN sending the at least one target signal is configured by the network device associated with the AMP device (specifically, it can be configured to the WCN and the AMP device); and / or, the WCN periodically sends the target signal, or the WCN sends the target signal after the AMP device or the network device associated with the AMP device requests or triggers it.
[0088] In some embodiments, the WCN is one of the following: an AP, a STA, a TRP, a base station, or a terminal device, whose location is known and whose transmission power and stored energy meet pre-defined conditions. In other words, an AP, a STA, a TRP, a base station, or a terminal device with a known location and sufficient transmission power and stored energy can also serve as a WCN.
[0089] In some embodiments, the first signal and the second signal satisfy at least one of the following association relationships: power-division multiplexing (PDM), time-division multiplexing (TDM), and frequency-division multiplexing (FDM). Of course, the first signal and the second signal may also satisfy other association relationships, which are not limited in the embodiments of the present application.
[0090] In some embodiments, the first signal and the second signal satisfy a PDM relationship, and the at least one target signal includes a first target signal; wherein the power of the first signal is μ1P1, and the power of the second signal is (1-μ1)P1; wherein P1 represents the power of the first target signal, μ1 represents the power allocation coefficient, P1 is a positive number, and μ1 is a non-negative number.
[0091] For example, in one time slot, μ1 is equal to 0.5, and the power is evenly distributed between the energy harvester and the positioning module.
[0092] For another example, in one time slot, μ1 can be adjusted to 0.75, and more power is allocated to the energy harvester because the energy storage level is lower.
[0093] For another example, in one time slot, μ1 can be adjusted to 0.25 because the positioning accuracy is lower than the required target, so more power should be allocated to the positioning signal.
[0094] For another example, in an extreme case, in one time slot, μ1 can be 1 and 0, where all power is allocated to the energy harvester and the positioning module respectively.
[0095] For example, as shown in FIG4 , the power of the first target signal is P1, and the power splitter distributes the power of the first target signal into a first signal (μ1P1) and a second signal ((1-μ1)P1). The AMP device obtains energy through the first signal and performs positioning according to the second signal.
[0096] In some embodiments, μ1 is determined based on at least one of the following: energy storage status of the AMP device, positioning accuracy, throughput of the AMP device (also referred to as instantaneous traffic), and a distance between the AMP device and the first device.
[0097] For example, for an AMP device closer to the first device (such as a WCN), μ1 can be small and the AMP device can still obtain sufficient energy. On the contrary, for an AMP device far away from the first device (such as a WCN), μ1 can be large to obtain more energy.
[0098] In some embodiments, μ1 is agreed upon by a protocol, or μ1 is configured by a network, or μ1 is determined by negotiation between the AMP device and the first device, or μ1 is determined by the first device based on one or more power allocation coefficients recommended by the AMP device.
[0099] In some embodiments, the first signal and the second signal satisfy a TDM relationship; wherein the first signal is the target signal received by the AMP device within μ2T1, and the second signal is the target signal received by the AMP device within (1-μ2)T1; wherein T1 represents the duration for the AMP device to receive the target signal, μ2 represents the time allocation coefficient, and both T1 and μ2 are positive numbers.
[0100] For example, as shown in Figure 5, the AMP device receives a joint signal (i.e., multiple target signals) with a duration of T1, and the time splitter allocates the target signal received within μ2T1 as the first signal, and allocates the target signal received within (1-μ2)T1 as the second signal ((1-μ1)P1). The AMP device obtains energy through the first signal and performs positioning based on the second signal.
[0101] In some embodiments, the target signal received by the AMP device within μ2T1 is continuous with the target signal received by the AMP device within (1-μ2)T1. That is, the same signal is used for energy harvesting and positioning phase measurement, and the target signal between μ2T1 and (1-μ2)T1 is continuous.
[0102] In some embodiments, the target signal received by the AMP device within μ2T1 is discontinuous from the target signal received by the AMP device within (1-μ2)T1. That is, different signals are used for energy harvesting and positioning phase measurement, and the target signal between μ2T1 and (1-μ2)T1 is discontinuous.
[0103] In some embodiments, different AMP devices correspond to different μ2s. For example, when the target signal received by the AMP device within μ2T1 is continuous with the target signal received by the AMP device within (1-μ2)T1, the different AMP devices correspond to different μ2s.
[0104] In some embodiments, different AMP devices correspond to the same μ2. For example, when the target signal received by the AMP device within μ2T1 is discontinuous from the target signal received by the AMP device within (1-μ2)T1, the different AMP devices correspond to the same μ2.
[0105] In some embodiments, μ2 is determined based on at least one of the following: energy storage status of the AMP device, positioning accuracy, throughput of the AMP device, and a distance between the AMP device and the first device.
[0106] For example, for an AMP device closer to the first device (such as a WCN), μ2 can be small and the AMP device can still obtain sufficient energy. On the contrary, for an AMP device far away from the first device (such as a WCN), μ2 can be large to obtain more energy.
[0107] In some embodiments, μ2 is agreed upon by a protocol, or μ2 is configured by a network, or μ2 is determined by negotiation between the AMP device and the first device, or μ2 is determined by the first device based on one or more power allocation coefficients recommended by the AMP device, or μ2 is determined by the first device based on the power allocation coefficients recommended by some or all AMP devices associated with the first device.
[0108] For example, when different AMP devices correspond to the same μ2, μ2 is determined by the first device based on the power allocation coefficients recommended by some or all AMP devices associated with the first device. For example, μ2 is the average of the power allocation coefficients recommended by some or all AMP devices associated with the first device.
[0109] In some embodiments, the first signal and the second signal satisfy PDM and TDM relationships;
[0110] The first signal is a signal with a power of μ1P2 obtained after power distribution of the target signal received by the AMP device within μ2T2, and the second signal is a signal with a power of (1-μ1)P2 obtained after power distribution of the target signal received by the AMP device within μ2T2 and the target signal received by the AMP device within (1-μ2)T2;
[0111] Among them, T2 represents the duration of the AMP device receiving the target signal, P2 represents the power of the target signal received by the AMP device, μ1 represents the power allocation coefficient, μ2 represents the time allocation coefficient, μ1 is a non-negative number, and T1, P2 and μ2 are all positive numbers.
[0112] For example, the first signal and the second signal satisfy the PDM and TDM relationship, as shown in FIG6 , a time splitter and a power splitter can be introduced simultaneously to generate the first signal and the second signal.
[0113] In some embodiments, the target signal received by the AMP device within μ2T2 is continuous with the target signal received by the AMP device within (1-μ2)T2. That is, the same signal is used for energy harvesting and positioning phase measurement, and the target signal between μ2T2 and (1-μ2)T2 is continuous.
[0114] In some embodiments, the target signal received by the AMP device within μ2T2 is discontinuous from the target signal received by the AMP device within (1-μ2)T2. That is, different signals are used for energy harvesting and positioning phase measurement, and the target signal between μ2T2 and (1-μ2)T2 is discontinuous.
[0115] In some embodiments, different AMP devices correspond to different μ2s. For example, when the target signal received by the AMP device within μ2T2 is continuous with the target signal received by the AMP device within (1-μ2)T2, the different AMP devices correspond to different μ2s.
[0116] In some embodiments, different AMP devices correspond to the same μ2. For example, when the target signal received by the AMP device within μ2T2 is discontinuous from the target signal received by the AMP device within (1-μ2)T2, the different AMP devices correspond to the same μ2.
[0117] In some embodiments, μ1 is determined based on at least one of the following: energy storage status of the AMP device, positioning accuracy, throughput of the AMP device, and a distance between the AMP device and the first device.
[0118] For example, for an AMP device closer to the first device (such as a WCN), μ1 can be small and the AMP device can still obtain sufficient energy. On the contrary, for an AMP device far away from the first device (such as a WCN), μ1 can be large to obtain more energy.
[0119] In some embodiments, μ1 is agreed upon by a protocol, or μ1 is configured by a network, or μ1 is determined by negotiation between the AMP device and the first device, or μ1 is determined by the first device based on one or more power allocation coefficients recommended by the AMP device.
[0120] In some embodiments, μ2 is determined based on at least one of the following: energy storage status of the AMP device, positioning accuracy, throughput of the AMP device, and a distance between the AMP device and the first device.
[0121] For example, for an AMP device closer to the first device (such as a WCN), μ2 can be small and the AMP device can still obtain sufficient energy. On the contrary, for an AMP device far away from the first device (such as a WCN), μ2 can be large to obtain more energy.
[0122] In some embodiments, μ2 is agreed upon by a protocol, or μ2 is configured by a network, or μ2 is determined by negotiation between the AMP device and the first device, or μ2 is determined by the first device based on one or more power allocation coefficients recommended by the AMP device, or μ2 is determined by the first device based on the power allocation coefficients recommended by some or all AMP devices associated with the first device.
[0123] For example, when different AMP devices correspond to the same μ2, μ2 is determined by the first device based on the power allocation coefficients recommended by some or all AMP devices associated with the first device. For example, μ2 is the average of the power allocation coefficients recommended by some or all AMP devices associated with the first device.
[0124] In some embodiments, the first signal and the second signal satisfy an FDM relationship, wherein the first signal and the second signal are target signals at frequencies f1 and f2, respectively, received by the AMP device. For example, as shown in FIG7 , the first signal is the target signal at frequency f1 received by the AMP device (signals of other frequencies are filtered by a filter), and the second signal is the target signal at frequency f2 received by the AMP device (signals of other frequencies are filtered by a filter). The AMP device obtains energy through the first signal and performs positioning based on the second signal.
[0125] Optionally, the first signal and the second signal correspond to different transmission configurations, respectively. That is, different transmission configurations can be applied to the two target signals (i.e., the first signal and the second signal). For example, for periodic transmission, the wireless charging signal (i.e., the first signal) and the positioning signal (i.e., the second signal) can correspond to different periodic configurations, respectively.
[0126] In some embodiments, f1 is agreed upon by a protocol, or f1 is configured by a network, or f1 is determined by negotiation between the AMP device and the first device, or f1 is determined by the first device based on one or more frequencies recommended by the AMP device.
[0127] In some embodiments, f2 is agreed upon by a protocol, or f2 is configured by a network, or f2 is determined by negotiation between the AMP device and the first device, or f2 is determined by the first device based on one or more frequencies recommended by the AMP device.
[0128] In some embodiments, the first signal and the second signal may also satisfy the PDM and FDM relationships. For example, for a target signal with a frequency of f1 (with a power of P3), a power allocation coefficient μ1 is introduced. Specifically, a power splitter is used to divide the target signal with a frequency of f1 into a portion for wireless charging (μ1P3) and another portion for positioning ((1-μ1)P3). That is, the first signal is a signal with a power of μ1P3 obtained after power distribution of the target signal with a frequency of f1, and the second signal is a signal with a power of (1-μ1)P3 obtained after power distribution of the target signal with a frequency of f1 and a target signal with a frequency of f2. For another example, for a target signal with a frequency of f2 (power of P4), a power distribution coefficient μ1 is introduced. Specifically, the target signal with a frequency of f2 is divided into a part for wireless charging (μ1P4) and another part for positioning ((1-μ1)P4) through a power splitter. That is, the first signal is a signal with a power of μ1P4 obtained after power distribution between the target signal with a frequency of f1 and the target signal with a frequency of f2, and the second signal is a signal with a power of (1-μ1)P4 obtained after power distribution between the target signal with a frequency of f2.
[0129] Therefore, in an embodiment of the present application, the AMP device can generate a first signal and a second signal with an associated relationship based on at least one received target signal, obtain energy through the first signal, and perform positioning based on the second signal, thereby reducing the signaling overhead required for positioning of the AMP device and improving system efficiency.
