[0016] The technical proposal of embodiments of this application will be described below with reference to the drawings of embodiments of this application. Clearly, the embodiments described are only some of the embodiments of this application, and not all of them. All other embodiments that a person skilled in the art can obtain without creative effort based on the embodiments of this application are all within the scope of protection of this application.

[0017] The technical invention of the embodiments of this application can be applied to various communication systems. Examples include wireless local area networks (WLAN), wireless fidelity (WiFi), or other communication systems. For example, the technical invention of the embodiments of this application can also be applied to the following communication systems: Global System for Mobile Communication (GSM) system, Code Division Multiple Access (CDMA) system, Wideband Code Division Multiple Access (WCDMA) system, General Packet Radio Service (GPRS), Long Term Evolution (LTE) system, LTE-A (Advanced Long Term Evolution) system, New Radio (NR) system, Advanced New Radio system, LTE-based access to unlicensed spectrum (LTE-U) system, NR-based access to unlicensed spectrum (NR-U) system, Non-Terrestrial Networks (NTN) system, Universal Mobile Telecommunication System (UMTS), Wireless Local Area Network (WLAN), Internet of Things (IoT), 5th generation (5G) communication system, 6th generation (6th Examples include communication systems such as generation (6G) communication systems.

[0018] Referring to FIG. 1, FIG. 1 is a schematic diagram showing a wireless communication system according to an embodiment of the present application. As shown in FIG. 1, the wireless communication system may include an access point (AP) and a station (STA).

[0019] In some scenarios, the AP may be referred to as an AP STA, that is, in a sense, the AP is also a type of STA. In some scenarios, the STA may be referred to as a non-AP STA.

[0020] In some embodiments, the STA may include an AP STA and a non-AP STA. The communication in the communication system may be communication between an AP and a non-AP STA, communication between non-AP STAs, or communication between a STA and a peer STA. The peer STA may refer to a device that communicates with the STA equivalently. For example, the peer STA may be an AP or a non-AP STA.

[0021] The AP corresponds to a bridge that connects a wired network to a wireless network. The main role of the AP is to connect various wireless network clients to each other and then connect the wireless network to Ethernet. The 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.

[0022] Note that the role of the STA in the communication system is not fixed. For example, in some scenarios, when a mobile phone connects to a router, the mobile phone is a non-AP STA. When the mobile phone is used as a hotspot for another mobile phone, the mobile phone functions as an AP.

[0023] APs and non-AP STAs may include devices applied to V2X (Vehicle to Everything), IoT nodes and sensors in the Internet of Things (IoT), smart cameras, smart remotes, smart water meters, smart electricity meters in smart homes, and sensors in smart cities.

[0024] In some embodiments, a non-AP STA may support the 802.11be standard. Furthermore, a non-AP STA may support multiple current and future 802.11 family WLAN standards, such as 802.11ax, 802.11ac, 802.11n, 802.11g, 802.11b, and 802.11a.

[0025] In some embodiments, the AP may be a device that supports the 802.11be standard. Alternatively, the AP may be a device that supports multiple current and future 802.11 family WLAN standards, such as 802.11ax, 802.11ac, 802.11n, 802.11g, 802.11b, and 802.11a.

[0026] In embodiments of this application, STA may be a mobile phone, tablet computer (Pad), computer, virtual reality (VR) device, augmented reality (AR) device, wireless device in industrial control, set-top box (STB), wireless device in self-driving, in-vehicle communication device, wireless device in remote medical, wireless device in smart grid, wireless device in transportation safety, wireless device in smart city, or wireless device in smart home, wireless communication chip, application-specific integrated circuit (ASIC), system-on-chip (SOC), etc., that supports WLAN / WIFI technology.

[0027] The frequency bands that may be supported by WLAN technology may include, but are not limited to, lower frequency bands (2.4 GHz (Giga Hertz), 5 GHz, 6 GHz) and higher frequency bands (45 GHz, 60 GHz).

[0028] One or more links exist between the station and the access point. In some embodiments, the station and access point support multi-band communication, for example, by communicating simultaneously on frequency bands 2.4GHz, 5GHz, 6GHz, 45GHz, and 60GHz, or on different channels in the same frequency band (or different frequency bands), thereby improving the throughput and / or reliability of communication between devices. Such devices are often called multi-band devices or multi-link devices (MLDs), and may also be called multi-link entities or multi-band entities. An MLD may be an access point or a station. If the MLD is an access point, it includes one or more APs. If the MLD is a station, it includes one or more non-AP STAs.

[0029] An MLD containing one or more APs may be called an AP MLD, and an MLD containing one or more non-AP STAs may be called a non-AP MLD.

[0030] In the embodiments of this application, an AP may include multiple APs, and a non-AP may include multiple STAs. Multiple links may be formed between APs within an AP and STAs within a non-AP, and data communication can be performed between APs within an AP and corresponding STAs within a non-AP via corresponding links.

[0031] An AP is a device deployed on a WLAN that provides wireless communication capabilities to a STA. A station may include user equipment (UE), access terminals, user units, user stations, mobile stations, mobile stations, remote stations, remote terminals, mobile devices, wireless communication devices, user agents, or user devices. Optionally, a station may be, but is not limited to, a cellular telephone, cordless telephone, session initiation protocol (SIP) telephone, wireless local loop (WLL) station, personal digital assistant (PDA), handheld device with wireless communication capabilities, computing device, or other processing device connected to a wireless modem, in-vehicle device, or wearable device.

[0032] Selectively, both the station and the access point support the IEEE (Institute of Electrical and Electronics Engineers) 802.11 standard.

[0033] In some embodiments, the communication system of the embodiments of this application can be applied to carrier aggregation (CA) scenarios, dual connectivity (DC) scenarios, standalone (SA) networking scenarios, or non-standalone (NSA) networking scenarios.

[0034] In some embodiments, the communication system in the embodiments of this application can be applied to an unlicensed spectrum, where the unlicensed spectrum can be considered a shared spectrum. Alternatively, the communication system in the embodiments of this application can be applied to a licensed spectrum, where the licensed spectrum can be considered a non-shared spectrum.

[0035] In some embodiments, the communication system in the embodiments of this application may be applied to FR1 (Frequency Range 1) (corresponding frequency bands from 410 MHz to 7.125 GHz), or to FR2 (Frequency Range 2) (corresponding frequency bands from 24.25 GHz to 52.6 GHz), or to higher frequency bands corresponding to new frequency bands, for example, frequency bands from 52.6 GHz to 71 GHz, or frequency bands from 71 GHz to 114.25 GHz.

[0036] In this specification, the terms "system" and "network" should be understood to be interchangeable. In this specification, the term "and / or" simply describes the relationship between related objects and indicates that there are three types of relationships. For example, A and / or B indicates three situations: A exists alone, A and B exist simultaneously, or B exists alone. Also in this specification, the symbol " / " generally indicates that the preceding and following related objects are in an "or" relationship.

[0037] The terminology used in the embodiments of this application is for the sole purpose of describing specific embodiments of this application and is not intended to limit this application. Terms such as “first,” “second,” “third,” and “fourth” in the specification, claims, and drawings of this application are used to distinguish different subjects, not to describe a specific sequence. Furthermore, terms such as “includes,” “composes,” and any other variants are intended to cover, without excluding, other components.

[0038] It should be understood that the term "indicate" as used in the embodiments of this application may be direct, indirect, or indicate a related relationship. For example, A indicating B may mean that A directly indicates B (for example, that B can be obtained by A), that A indirectly indicates B (for example, that A indicates C and B can be obtained by C), or that there is a related relationship between A and B.

[0039] In the description of the embodiments of this application, the term "corresponding" may mean that there is a direct or indirect corresponding relationship between the two, or that there is a related relationship between the two, or that there is a relationship such as instruction and instruction, setting and non-setting.

[0040] In embodiments of this application, “predefined” or “pre-configured” can be achieved by pre-storing corresponding codes or corresponding tables in a device (including, for example, terminal devices and network devices), or by other means that can be used to indicate relevant information, and the specific methods of such implementation are not limited in this application. For example, “predefined” may mean defined in a protocol.

[0041] In embodiments of this application, “protocol” may mean a standard protocol in the field of communications. For example, it may be an evolution of a conventional LTE protocol, NR protocol, Wi-Fi protocol, or other related communication system protocol. This application is not limited to the type of protocol.

[0042] To better understand the embodiments of this application, the positioning method relating to this application will be described.

[0043] Over the long term, timing-based, angle-based, and carrier phase-based positioning methods have been used in Wi-Fi, 4G, 5G, and Global Navigation Satellite System (GNSS) networks. Due to extremely limited power and processing capabilities, AMP devices cannot transmit broadband positioning reference signals (PRS), and as a result, timing-based positioning methods (e.g., Observed Time Difference of Arrival, OTDOA) cannot achieve good positioning accuracy. For similar reasons, angle-based positioning methods are also unsuitable, as AMP devices cannot accurately position incoming signals relative to their angle and cannot transmit / reflect fairly directional signals.

[0044] To better understand the embodiments of this application, an AMP device relating to this application will be described.

[0045] AMP devices can collect energy from various energy sources, including radio frequency (RF) radio, solar energy, and thermal energy. RF radio is the most controllable energy source of all. For RF radio energy collection, narrowband S1G (Sub-1GHz) signals are more suitable for energy harvesting by AMP devices due to their good propagation characteristics.

[0046] AMP devices may also be called Ambient Power Enabled IoT devices, and are abbreviated as Ambient IoT devices. Specifically, an Ambient IoT device refers to an IoT device that utilizes various types of environmental energy, such as radio frequency energy, light energy, solar energy, thermal energy, and mechanical energy. Ambient IoT devices do not need to have energy storage capabilities, or they may have very limited energy storage capabilities (for example, a capacitor with a capacitance of several tens of microfarads (μF) may be used).

[0047] In some embodiments, ambient IoT devices can be used in at least the following four types of scenarios. Object recognition in logistics, product management on production lines, and supply chain management. Environmental monitoring, including monitoring of temperature, humidity, and harmful gases in the operating and natural environments. Positioning applications include indoor positioning, smart object detection, and object positioning on production lines. Smart control of various electrical appliances in smart homes (on / off air conditioners, temperature control), and smart control of various facilities in agricultural greenhouses (automatic watering, fertilization).

[0048] To better understand the embodiments of this application, the problems that this application aims to solve will be described.

[0049] Given the limitations of AMP devices and their power consumption, how AMP devices perform positioning is a problem that needs to be solved.

[0050] In view of the above problems, this application proposes a solution for positioning using an AMP device and provides a design for a joint signal for wireless charging and positioning. The AMP device can generate a related first signal and a second signal based on at least one received target signal. The AMP device collects energy from the first signal and performs positioning based on the second signal. This reduces the signaling overhead required for positioning by the AMP device and improves system efficiency.

[0051] Specifically, narrowband S1G signals are more suitable for energy collection by AMP devices due to their good propagation characteristics. Furthermore, narrowband S1G signals can also be used for phase-based positioning. In other words, low-frequency signals, such as S1G signals, are more suitable for achieving reasonable wireless charging distances. The same signal can be used for both energy collection and phase-based positioning.

[0052] To facilitate understanding of the technical proposal of the embodiments of this application, the technical proposal of this application will be described in detail below with reference to specific embodiments. Hereinafter, related technologies can be optionally combined with the technical proposal of the embodiments of this application, and all of them fall within the scope of protection of the embodiments of this application. The embodiments of this application include at least a portion of the following:

[0053] Figure 2 is a flowchart of a wireless communication method 200 according to an embodiment of this application. As shown in Figure 2, the wireless communication method 200 may include at least a part of the following:

[0054] S210: The first device transmits at least one target signal to the AMP device.

[0055] S220: The AMP device receives at least one target signal transmitted by the first device. This at least one target signal is used to generate a first signal and a second signal that are related to each other.

[0056] S230: The AMP device collects energy from the first signal and performs positioning based on the second signal.

[0057] In the embodiments of this application, the AMP device can generate a related first signal and a second signal based on at least one received target signal. The AMP device collects energy from the first signal and performs positioning based on the second signal. This reduces the signaling overhead required for positioning by the AMP device and improves system efficiency.

[0058] In some embodiments, the at least one target signal is a narrowband S1G signal. Naturally, the at least one target signal may be other signals or other narrowband signals. The embodiments of this application are not limited thereto. Specifically, narrowband S1G signals are more suitable for energy collection by AMP devices because of their good propagation characteristics.

[0059] It should be noted that communication signal reception sensitivity and RF radio energy collection sensitivity are clearly different. For example, in WLAN, the range of the Received Signal Strength Indication (RSSI) is from -20 dBm (very close to the AP) to -95 dBm (far from the AP). Assuming a 10 dBm margin to account for unavoidable RSSI fluctuations in the link budget, a WLAN device (e.g., an 802.11b / g WLAN device) can maintain a wireless connection against signals stronger than -84 dBm. In contrast, energy collection sensitivity is only down to -35 dBm. A difference of 49 dBm means that the wireless charging distance is much shorter than the communication distance.

[0060] AMP devices have a very bright market outlook in many scenarios, such as smart homes, smart manufacturing, and logistics / warehouses. Because AMP devices offer ultra-low cost and maintenance-free functionality, entirely new markets have been opened up. The technology proposed in this application can be applied when a cost-effective, maintenance-free, and highly accurate positioning AMP device is required. Embodiments of this application provide a technology / process applicable to positioning systems that have RF radio energy collection capabilities and are based on AMP devices.

[0061] In the embodiments of this application, a wireless charging node (WCN), which is a novel node primarily for transmitting wireless charging signals, is designed and deployed. The WCN can charge AMP devices that are not wirelessly chargeable and are within the communication coverage. Specifically, the WCN can significantly reduce the complexity and cost of charging AMP devices by primarily transmitting wireless charging signals.

[0062] In some embodiments, the deployment density of the WCN should be higher than the deployment density of the normal communication nodes (e.g., APs). As shown in Figure 3, all AMP devices are within communication coverage, but only AMP1 and AMP2 are within the AP's wireless charging coverage. WCN1 is deployed to AMP3 primarily for wireless charging, and WCN2 is deployed to AMP4 primarily for wireless charging. Specifically, narrowband S1G signals can be suitable for wireless charging. Narrowband S1G signals can also be used for phase-based positioning to improve efficiency and reduce signaling overhead. For example, AMP3 can receive communication signals from the AP and wireless charging signals from WCN1. AMP4 can receive communication signals from the AP and wireless charging signals from WCN2. Selectively, at least one of the above target signals may be transmitted by the AP or by the WCN. If wireless charging signals can also be used for positioning, AMP devices can receive more positioning signals, thereby improving positioning accuracy. Because WCNs have the lowest complexity and cost requirements, data processing modules such as modulation / demodulation and encoding / decoding are absent.

[0063] In some embodiments, the first device is at least one of a WCN, AP, STA, Transmission Reception Point (TRP), base station, or terminal device. Selectively, if the first device is a device other than a WCN, the location of the first device is known, and the transmit power of the first device and the energy stored by the first device satisfy predetermined conditions. Specifically, for example, these predetermined conditions are determined by agreement between the first device and the AMP device, or by the first device.

[0064] In some embodiments, the first device is a WCN. Specifically, before the WCN transmits the at least one target signal, the network device associated with the AMP device has already obtained the WCN's location information, and / or the associated settings for the WCN to transmit the at least one target signal are set by the network device associated with the AMP device (specifically, they can be set for the WCN and the AMP device), and / or the WCN transmits a target signal periodically, or after being requested or triggered by the AMP device or the network device associated with the AMP device.

[0065] In some embodiments, the WCN is at least one of an AP, STA, TRP, base station, or terminal device whose location is known and whose transmit power and stored energy satisfy predetermined conditions. Specifically, an AP, STA, TRP, base station, or terminal device whose location is known and has sufficient transmit power and sufficient stored energy can also be used as a WCN.

[0066] In some embodiments, the first signal and the second signal satisfy at least one of the following relationships: power-division multiplexing (PDM), time-division multiplexing (TDM), and frequency-division multiplexing (FDM). Naturally, the first signal and the second signal may satisfy other relationships, and are not limited to those in the embodiments of this application.

[0067] In some embodiments, the first signal and the second signal satisfy a PDM relationship. The at least one target signal includes the first target signal. The power of the first signal is μ1P1, and the power of the second signal is (1-μ1)P1. P1 represents the power of the first target signal. μ1 represents the power splitting factor. P1 is a positive number, and μ1 is a non-negative number.

[0068] For example, in one slot, μ1 is 0.5. Power is split equally between the energy harvester and the positioning module.

[0069] Furthermore, for example, in one slot, μ1 can be adjusted to 0.75. Due to the lower energy storage level, more power is allocated to the energy harvester.

[0070] Furthermore, for example, in one slot, μ1 can be adjusted to 0.25. Since the positioning accuracy is lower than the required target accuracy, more power should be allocated to the positioning signal.

[0071] Furthermore, in extreme cases, for example, in a single slot, μ1 may be 1 or 0. All power is allocated to the energy harvester or positioning module.

[0072] Specifically, as shown in Figure 4, for example, the power of the first target signal is P1. The power splitter splits the power of the first target signal into a first signal (μ1P1) and a second signal ((1-μ1)P1). The AMP device collects energy from the first signal and performs positioning based on the second signal.

[0073] In some embodiments, μ1 is identified by at least one of the following: the energy storage state of the AMP device, the positioning accuracy of the AMP device, the throughput of the AMP device (which may be called instantaneous traffic), and the distance between the AMP device and the first device.

[0074] For example, for an AMP device closer to the first device (e.g., WCN), μ1 may be very small. In this case, the AMP device can still collect sufficient energy. Conversely, for an AMP device farther from the first device (e.g., WCN), μ1 may be very large in order to collect more energy.

[0075] In some embodiments, μ1 is promised by a protocol, or μ1 is set by a network, or μ1 is identified by an agreement between the AMP device and the first device, or μ1 is identified by the first device based on one or more power split factors recommended by the AMP device.

[0076] In some embodiments, the first signal and the second signal satisfy a TDM relationship. The first signal is the target signal received by the AMP device within μ2T1. The second signal is the target signal received by the AMP device within (1-μ2)T1. T1 represents the duration for which the AMP device receives the target signal. μ2 represents the time split factor. Both T1 and μ2 are positive numbers.

[0077] Specifically, as shown in Figure 5, for example, the AMP device receives a joint signal (i.e., multiple target signals) with a duration of T1. The time splitter assigns the target signals received within μ2T1 as the first signal and the target signals received within (1-μ2)T1 as the second signal. The AMP device collects energy from the first signal and performs positioning based on the second signal.

[0078] In some embodiments, the target signal received by the AMP device in μ2T1 and the target signal received by the AMP device in (1-μ2)T1 are continuous. That is, the same signal is used for phase measurement for energy acquisition and positioning. The target signals between μ2T1 and (1-μ2)T1 are continuous.

[0079] In some embodiments, the target signal received by the AMP device in μ2T1 and the target signal received by the AMP device in (1-μ2)T1 are discontinuous. That is, different signals are used for phase measurement for energy acquisition and positioning. The target signals between μ2T1 and (1-μ2)T1 are discontinuous.

[0080] In some embodiments, different AMP devices correspond to different μ2. For example, if the target signal received by the AMP device within μ2T1 and the target signal received by the AMP device within (1-μ2)T1 are continuous, then different AMP devices correspond to different μ2.

[0081] In some embodiments, different AMP devices correspond to the same μ2. For example, different AMP devices correspond to the same μ2 if the target signal received by the AMP device within μ2T1 and the target signal received by the AMP device within (1-μ2)T1 are discontinuous.

[0082] In some embodiments, μ2 is identified by at least one of the following: the energy storage state of the AMP device, the positioning accuracy of the AMP device, the throughput of the AMP device, and the distance between the AMP device and the first device.

[0083] For example, for an AMP device closer to the first device (e.g., WCN), μ2 may be very small. In this case, the AMP device can still collect sufficient energy. Conversely, for an AMP device farther from the first device (e.g., WCN), μ2 may be very large in order to collect more energy.

[0084] In some embodiments, μ2 is promised by a protocol, or configured by a network, or identified by an agreement between the AMP device and the first device, or identified by the first device based on one or more power split factors recommended by the AMP device, or identified by the first device based on some or all of the power split factors recommended by the AMP devices associated with the first device.

[0085] Specifically, for example, if different AMP devices correspond to the same μ2, μ2 is identified by the first device based on the power split factors recommended by some or all of the AMP devices associated with that first device. For example, μ2 is the average value of the power split factors recommended by some or all of the AMP devices associated with the first device.

[0086] In some embodiments, the first signal and the second signal satisfy PDM and TDM relationships. The first signal is a signal with power μ1P2 obtained by power splitting the target signal received by the AMP device within μ2T2. The second signal includes a signal with power (1-μ1)P2 obtained by power splitting the target signal received by the AMP device within μ2T2, and the target signal received by the AMP device within (1-μ2)T2. T2 represents the duration for which the AMP device receives the target signal. P2 represents the power of the target signal received by the AMP device. μ1 represents the power split factor, and μ2 represents the time split factor. μ1 is a non-negative number, while T1, P2, and μ2 are all positive numbers.

[0087] Specifically, for example, the first signal and the second signal satisfy the PDM and TDM relationships. As shown in Figure 6, both a time splitter and a power splitter can be introduced to generate the first and second signals.

[0088] In some embodiments, the target signal received by the AMP device within μ2T2 and the target signal received by the AMP device within (1-μ2)T2 are continuous. That is, the same signal is used for phase measurement for energy acquisition and positioning. The target signal between μ2T2 and (1-μ2)T2 is continuous.

[0089] In some embodiments, the target signal received by the AMP device in μ2T2 and the target signal received by the AMP device in (1-μ2)T2 are discontinuous. That is, different signals are used for phase measurement for energy acquisition and positioning. The target signals between μ2T2 and (1-μ2)T2 are discontinuous.

[0090] In some embodiments, different AMP devices correspond to different μ2. For example, if the target signal received by the AMP device within μ2T2 and the target signal received by the AMP device within (1-μ2)T2 are continuous, then different AMP devices correspond to different μ2.

[0091] In some embodiments, different AMP devices correspond to the same μ2. For example, different AMP devices correspond to the same μ2 if the target signal received by the AMP device within μ2T2 and the target signal received by the AMP device within (1-μ2)T2 are discontinuous.

[0092] In some embodiments, μ1 is identified by at least one of the following: the energy storage state of the AMP device, the positioning accuracy of the AMP device, the throughput of the AMP device, and the distance between the AMP device and the first device.

[0093] For example, for an AMP device closer to the first device (e.g., WCN), μ1 may be very small. In this case, the AMP device can still collect sufficient energy. Conversely, for an AMP device farther from the first device (e.g., WCN), μ1 may be very large in order to collect more energy.

[0094] In some embodiments, μ1 is promised by a protocol, or μ1 is set by a network, or μ1 is identified by an agreement between the AMP device and the first device, or μ1 is identified by the first device based on one or more power split factors recommended by the AMP device.

[0095] In some embodiments, μ2 is identified by at least one of the following: the energy storage state of the AMP device, the positioning accuracy of the AMP device, the throughput of the AMP device, and the distance between the AMP device and the first device.

[0096] For example, for an AMP device closer to the first device (e.g., WCN), μ2 may be very small. In this case, the AMP device can still collect sufficient energy. Conversely, for an AMP device farther from the first device (e.g., WCN), μ2 may be very large in order to collect more energy.

[0097] In some embodiments, μ2 is promised by a protocol, or configured by a network, or identified by an agreement between the AMP device and the first device, or identified by the first device based on one or more power split factors recommended by the AMP device, or identified by the first device based on some or all of the power split factors recommended by the AMP devices associated with the first device.

[0098] Specifically, for example, if different AMP devices correspond to the same μ2, μ2 is identified by the first device based on the power split factors recommended by some or all of the AMP devices associated with that first device. For example, μ2 is the average value of the power split factors recommended by some or all of the AMP devices associated with the first device.

[0099] In some embodiments, the first signal and the second signal satisfy an FDM relationship. The first signal is the target signal with frequency f1 received by the AMP device. The second signal is the target signal with frequency f2 received by the AMP device. Specifically, as shown in Figure 7, for example, the first signal is the target signal with frequency f1 received by the AMP device (signals of other frequencies are filtered out), and the second signal is the target signal with frequency f2 received by the AMP device (signals of other frequencies are filtered out). The AMP device collects energy from the first signal and performs positioning based on the second signal.

[0100] Selectively, the first signal and the second signal correspond to different transmission configurations. That is, different transmission configurations can be applied to 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.

[0101] In some embodiments, f1 is promised by a protocol, or set by a network, or identified by an agreement between the AMP device and the first device, or identified by the first device based on one or more frequencies recommended by the AMP device.

[0102] In some embodiments, f2 is promised by a protocol, or f2 is set by a network, or f2 is identified by an agreement between the AMP device and the first device, or f2 is identified by the first device based on one or more frequencies recommended by the AMP device.

[0103] In some embodiments, the first signal and the second signal can also satisfy PDM and FDM relationships. For example, a power split factor μ1 is introduced for a target signal with frequency f1 (with power P3). Specifically, the target signal with frequency f1 is further split by a power splitter, with part used for wireless charging (μ1P3) and the other part used for positioning ((1-μ1)P3). That is, the first signal is a signal with power μ1P3 obtained by power splitting the target signal with frequency f1. The second signal includes a signal with power (1-μ1)P3 obtained by power splitting the target signal with frequency f1, and a target signal with frequency f2. Also, for example, a power split factor μ1 is introduced for a target signal with frequency f2 (with power P4). Specifically, the target signal with frequency f2 is further split by a power splitter, with part of it used for wireless charging (μ1P4) and the other part used for positioning ((1-μ1)P4). That is, the first signal includes the signal with power μ1P4 obtained by power splitting the target signal with frequency f2, and the target signal with frequency f1. The second signal is the signal with power (1-μ1)P4 obtained by power splitting the target signal with frequency f2.

[0104] Therefore, in the embodiments of this application, the AMP device can generate a related first signal and a second signal based on at least one received target signal. The AMP device collects energy from the first signal and performs positioning based on the second signal. This reduces the signaling overhead for positioning by the AMP device and improves system efficiency.
