Description

Technical Field

[0001] This application relates to the field of communication technology, specifically to a communication method and corresponding device. Background Technology

[0002] With the development of wireless networks and the evolution of business needs, there are massive numbers of Internet of Things (IoT) nodes in the network. These IoT nodes are low-cost and small in size, but cannot carry large-capacity batteries, resulting in short standby life.

[0003] Therefore, the power supply problem of IoT nodes urgently needs to be solved. Summary of the Invention

[0004] This application provides a communication method for reducing the complexity of wireless charging. This application also provides corresponding apparatus, computer-readable storage media, and computer program products.

[0005] The first aspect of this application provides a communication method that can be applied to a terminal device, such as a terminal device or a communication module within a terminal device, or a circuit or chip (such as a modem chip, also known as a baseband chip, or a system-on-chip (SoC) chip or system-in-package (SIP) chip containing a modem core) responsible for communication functions within the terminal device. Taking the application of this method to a terminal device as an example, in this method, the terminal device receives a first request from a first communication device; wherein the first request includes first information and second information, the first information being used to indicate a wireless charging mode, and the second information including information related to the wireless charging mode; charging is performed according to the wireless charging mode based on the first information and the second information.

[0006] In this application, the first communication device can be a network device, a component or device applied to a network device (e.g., a processor, chip, or chip system), or a logic module or software capable of implementing all or part of the functions of the network device (e.g., a central unit (CU), a distributed unit (DU), or a radio unit (RU)). Of course, the first communication device can also be a terminal device, a component or device applied to a terminal device (e.g., a processor, chip, or chip system), or a logic module or software capable of implementing all or part of the functions of the terminal device.

[0007] In this application, the first request can be a query request sent by the reader of the electronic tag to the electronic tag. Of course, the first request can also be other types of requests or messages, and this application does not limit it.

[0008] In this application, the first information can be indication information that indicates different content through a bit sequence formed by one or more bits. The first information is used to indicate a wireless charging mode, and there can be one or more wireless charging modes. When there are multiple modes, different bit sequences can correspond to different wireless charging modes, and different wireless charging modes correspond to different wireless charging procedures.

[0009] In this application, the second information may include one or more pieces of information (also referred to as parameters), which can be understood as indication information of specific content related to the wireless charging mode. "Related" means that the second information corresponding to different wireless charging modes may be the same or different, where different includes partial or complete differences. Furthermore, the number of pieces of information related to different wireless charging modes may be different. For example, there may be 5 pieces of information related to wireless charging mode 1 and 7 pieces of information related to wireless charging mode 2, and 5 of these 7 pieces of information may be the same as the 5 pieces of information related to wireless charging mode 1. Of course, these 5 pieces of information may also be partially the same or completely different.

[0010] In this application, the process of charging according to the wireless charging mode based on the first information and the second information refers to determining the charging process according to the wireless charging mode indicated by the first information and completing the charging process according to the specific content of one or more information in the second information.

[0011] In the first aspect described above, the first communication device sends a first request to the second communication device. The first and second information in the first request indicate a wireless charging mode and related information. Upon receiving the first request, the second communication device can perform wireless charging based on the first and second information. Wireless charging can be completed without the second or first communication device needing to send a reference signal related to channel measurement to the other party in advance, nor without the first communication device needing to perform channel estimation and precoding based on the reference signal. This saves the power consumed by the second or first communication device in sending the reference signal, conserves transmission resources for the reference signal, and reduces the complexity of the first communication device performing channel estimation and precoding based on the reference signal. Furthermore, not all second communication devices possess channel measurement capabilities; therefore, the wireless charging process provided in this application expands the types of second communication devices capable of wireless charging.

[0012] In one possible implementation, the first information is used to indicate the wireless charging mode for activating beam scanning, and the second information includes the time when the first communication device starts beam scanning and the open-loop beam scanning type; the above steps: charging according to the wireless charging mode based on the first and second information include: activating the function of scanning the beam according to the wireless charging mode for activating beam scanning; and collecting energy from the beam emitted by the first communication device for charging after the first communication device starts beam scanning, based on the time when the first communication device starts beam scanning and the open-loop beam scanning type.

[0013] In this application, after the first communication device sends a first request, it will send one or more beams, each of which carries energy. After receiving the first request, the second communication device can activate the scanning function of one or more beams according to the wireless charging mode for activating beam scanning indicated by the first information.

[0014] In this application, the time when the first communication device begins beam scanning refers to the time when the first communication device transmits one or more beams, so that the second communication device can determine the start time of scanning one or more beams.

[0015] In this application, the open-loop beam scanning type refers to a scanning type that does not require a second communication device to feed back the measurement results of one or more beams. It can also be understood as an open-loop beam scanning type that directly collects energy from one or more scanning beams for wireless charging.

[0016] In this possible implementation, when the first information indicates the activation of the wireless charging mode for beam scanning and the second information includes the open-loop beam scanning type, the second communication device will directly collect energy from the beam after the first communication device sends the beam for wireless charging, which can improve the efficiency of wireless charging of the second communication device.

[0017] In one possible implementation, the method further includes: receiving a second request from a first communication device; wherein the second request is for requesting feedback on wireless charging; and sending feedback information to the first communication device to indicate the charging result.

[0018] In this possible implementation, the first communication device can request the charging result from the second communication device via a second request. After the second communication device sends feedback information indicating the charging result, the first communication device can determine the next charging time for the second communication device based on this feedback information, thereby improving the accuracy of charging management.

[0019] In one possible implementation, the first information is used to indicate a wireless charging mode that activates beam scanning, or the first information is used to indicate a wireless charging mode that activates beam feedback; the second information includes the time when the first communication device starts beam scanning and the closed-loop beam scanning type; the above steps: charging according to the first and second information and the wireless charging mode include: activating the beam feedback function according to the wireless charging mode that activates beam scanning or the wireless charging mode that activates beam feedback; and after the first communication device starts beam scanning, measuring the energy in the beam emitted by the first communication device to determine the first feedback information, which is used for charging, based on the time when the first communication device starts beam scanning and the closed-loop beam scanning type.

[0020] In this application, the wireless charging mode with activated beam scanning refers to activating the scanning function of one or more beams transmitted by the first communication device. The wireless charging mode with activated beam feedback refers to first measuring the energy of one or more beams transmitted by the first communication device, feeding back the measurement results, and then completing the wireless charging according to further instructions from the first communication device.

[0021] In this application, the closed-loop beam scanning type refers to the requirement that a second communication device feeds back the measurement results for one or more beams.

[0022] In this application, the first feedback information includes at least one of the following: information of the target beam, information of the charging capability of each beam in the beams transmitted by the first communication device, or information of the ranking of the charging capabilities of each beam; wherein, the target beam is the beam in the beams transmitted by the first communication device whose charging capability meets the charging requirements, such as: the target beam is the beam with the best charging capability or charging effect.

[0023] In this possible implementation, when the first information indicates either a wireless charging mode activating beam scanning or a wireless charging mode activating beam feedback, and the second information includes a closed-loop beam scanning type, the second communication device will measure the beam transmitted by the first communication device after the first communication device transmits the beam to determine the first feedback information, such as the beam with the best charging capability or charging effect. This allows the first communication device to subsequently perform more efficient wireless charging on the second communication device based on the first feedback information.

[0024] In one possible implementation, the method further includes: receiving a third request from a first communication device; wherein the third request includes feedback resources for the first feedback information, and the feedback resources include at least one of time-domain resources or frequency-domain resources; and sending the first feedback information to the first communication device based on at least one of the time-domain resources or frequency-domain resources of the first feedback information.

[0025] In this possible implementation, the first communication device can notify the second communication device of the feedback resources for sending the first feedback information through a third request. In this way, the first communication device can receive the first feedback information on the corresponding time domain resources or frequency domain resources, which helps to improve the accuracy of the feedback.

[0026] In one possible implementation, when the first information is used to indicate a wireless charging mode that activates beam feedback, the second information further includes feedback resources for the first feedback information, and the feedback resources include at least one of time-domain resources or frequency-domain resources; the method further includes: sending the first feedback information to a first communication device according to at least one of the time-domain resources or frequency-domain resources of the first feedback information.

[0027] In this possible implementation, when the first information is used to indicate the activation of the wireless charging mode for beam feedback, the second information may include time-domain or frequency-domain resources for indicating the feedback of the first feedback information. In this way, the first feedback information can be fed back without the first communication device sending a third request to the second communication device, reducing the occupation of transmission resources required to indicate the first feedback information.

[0028] In one possible implementation, the method further includes: receiving a target beam; and collecting energy from the target beam for recharging.

[0029] In this possible implementation, if the second communication device needs to send the first feedback information first, receiving the target beam for charging can improve the efficiency of wireless charging.

[0030] In one possible implementation, the second information may further include at least one of the following: the number of beams transmitted by the first communication device, the duration of each beam scan, or the end time of each beam scan.

[0031] In this possible implementation, different information in the second information can indicate different content. By using the above multiple pieces of information, the charging efficiency of the first communication device for wireless charging of the second communication device can be improved.

[0032] The second aspect of this application provides a communication method that can be applied to a network device, such as a network device or a communication module within a network device, or a circuit or chip (such as a modem chip, also known as a baseband chip, or a system-on-chip (SoC) chip or system-in-package (SIP) chip containing a modem core) responsible for communication functions within the network device. Taking the application of this method to a network device as an example, in this method, the network device sends a first request; wherein the first request includes first information and second information, the first information being used to indicate a wireless charging mode, and the second information including information related to the wireless charging mode; and a beam is transmitted, the beam being used for wireless charging.

[0034] In the second aspect described above, the first communication device sends a first request to the second communication device. The first and second information in the first request indicate a wireless charging mode and information related to the wireless charging mode. After receiving the first request, the second communication device can perform wireless charging based on the first and second information. Wireless charging can be completed without the second or first communication device needing to send a reference signal related to channel measurement to the other party in advance, nor without the first communication device needing to perform channel estimation and precoding based on the reference signal. This saves the power consumed by the second or first communication device in sending the reference signal, saves transmission resources for transmitting the reference signal, and reduces the complexity of channel estimation and precoding performed by the first communication device based on the reference signal. Furthermore, not all second communication devices have channel measurement capabilities; therefore, the wireless charging process provided in this application also expands the types of second communication devices that can perform wireless charging.

[0035] In one possible implementation, the first information is used to indicate the wireless charging mode for activating beam scanning, and the second information includes the time when the first communication device starts beam scanning and the open-loop beam scanning type; wherein, the wireless charging mode for activating beam scanning is used by the second communication device to activate the function of scanning the beam; the time when beam scanning starts and the open-loop beam scanning type are used by the second communication device to collect energy from the beam emitted by the first communication device for charging after the first communication device starts beam scanning.

For example, network equipment can be a RAN node (or device) that connects terminal devices to the wireless network, and can also be called a base station. Currently, some examples of RAN equipment include: base station, evolved NodeB (eNodeB), gNB (gNodeB) in 5G communication systems, transmission reception point (TRP), evolved Node B (eNB), radio network controller (RNC), Node B (NB), home base station (e.g., home-evolved Node B, or home Node B, HNB), base band unit (BBU), or wireless fidelity (Wi-Fi) access point (AP), etc. In addition, in a network architecture, network equipment can include central unit (CU) nodes, distributed unit (DU) nodes, or RAN equipment including both CU and DU nodes.

[0109] Optionally, the RAN node can also be a macro base station, micro base station, indoor station, relay node, donor node, or a radio controller in a cloud radio access network (CRAN) scenario. The RAN node can also be a server, wearable device, vehicle, or in-vehicle equipment. For example, the access network equipment in vehicle-to-everything (V2X) technology can be a roadside unit (RSU).

[0110] In another possible scenario, multiple RAN nodes collaborate to assist the terminal in achieving wireless access, with different RAN nodes each implementing some of the base station's functions. For example, RAN nodes can be CUs, DUs, CUs (control plane, CP), CUs (user plane, UP), or radio units (RUs). CUs and DUs can be set up separately or included in the same network element, such as a baseband unit (BBU). RUs can be included in radio equipment or radio units, such as remote radio units (RRUs), active antenna units (AAUs), radio heads (RHs), or remote radio heads (RRHs).

[0111] In different systems, CU (or CU-CP and CU-UP), DU, or RU may have different names, but those skilled in the art will understand their meaning. For example, in an open access network (open RAN, O-RAN, or ORAN) system, CU can also be called O-CU (open CU), DU can also be called O-DU, CU-CP can also be called O-CU-CP, CU-UP can also be called O-CU-UP, and RU can also be called O-RU. For ease of description, this application uses CU, CU-CP, CU-UP, DU, and RU as examples. Any of the units among CU (or CU-CP, CU-UP), DU, and RU in this application can be implemented through software modules, hardware modules, or a combination of software modules and hardware modules.

[0112] Communication between access network devices and terminal devices follows a specific protocol layer structure. This protocol layer may include a control plane protocol layer and a user plane protocol layer. The control plane protocol layer may include at least one of the following: radio resource control (RRC) layer, packet data convergence protocol (PDCP) layer, radio link control (RLC) layer, media access control (MAC) layer, or physical (PHY) layer, etc. The user plane protocol layer may include at least one of the following: service data adaptation protocol (SDAP) layer, PDCP layer, RLC layer, MAC layer, or physical layer, etc.

[0113] The correspondence between network elements and their achievable protocol layer functions in the ORAN system can be found in Table 1 below.

[0116] Network devices can be other devices that provide wireless communication functions for terminal devices. The embodiments of this application do not limit the specific technology or form of the network device. For ease of description, the embodiments of this application are not limited.

[0117] Network equipment may also include core network equipment, such as the Mobility Management Entity (MME), Home Subscriber Server (HSS), Serving Gateway (S-GW), Policy and Charging Rules Function (PCRF), and Public Data Network Gateway (PDN gateway or P-GW) in 4th generation (4G) networks; and access and mobility management function (AMF), user plane function (UPF), or session management function (SMF) in 5G networks. Furthermore, this core network equipment may also include other core network equipment in 5G networks and next-generation networks of 5G networks.

[0118] In this embodiment of the application, the network device may also have network nodes with AI capabilities, which can provide AI services to terminal devices or other network devices. For example, it may be an AI node, computing power node, RAN node with AI capabilities, core network element with AI capabilities, etc. on the network side (access network or core network).

[0119] In this application embodiment, the device for implementing the function of the network device can be the network device itself, or it can be a device capable of supporting the network device in implementing the function, such as a chip system. This device can be disposed within the network device. In the technical solutions provided in this application embodiment, the example of a network device being used to implement the function of the network device is used to describe the technical solutions provided in this application embodiment.

[0120] (3) The terms "system" and "network" in the embodiments of this application can be used interchangeably. "Multiple" refers to two or more. "And / or" describes the relationship between related objects, indicating that there can be three relationships. For example, A and / or B can mean: A exists alone, A and B exist simultaneously, or B exists alone, where A and B can be singular or plural. The character " / " generally indicates that the related objects before and after are in an "or" relationship. "At least one of the following" or similar expressions refer to any combination of these items, including any combination of single or plural items. For example, "at least one of A, B and C" includes A, B, C, AB, AC, BC or ABC. And, unless otherwise specified, the ordinal numbers such as "first" and "second" mentioned in the embodiments of this application are used to distinguish multiple objects and are not used to limit the order, sequence, priority or importance of multiple objects.

[0121] (4) In the embodiments of this application, "send" and "receive" indicate the direction of signal transmission. For example, "send information to XX" can be understood as the destination of the information being XX, which may include sending directly through the air interface or sending indirectly through the air interface by other units or modules. "Receive information from YY" can be understood as the source of the information being YY, which may include receiving directly from YY through the air interface or receiving indirectly from YY through the air interface by other units or modules. "Send" can also be understood as the "output" of the chip interface, and "receive" can also be understood as the "input" of the chip interface.

[0122] In other words, sending and receiving can occur between devices, such as between network devices and terminal devices, or within a device, such as between components, modules, chips, software modules, or hardware modules within the device via buses, wiring, or interfaces.

[0123] It is understandable that information may undergo necessary processing, such as encoding and modulation, between the source and destination, but the destination can understand the valid information from the source. Similar statements in this application can be interpreted in a similar way and will not be elaborated further.

[0124] (5) The communication or charging in the embodiments of this application may include: wireless communication or charging between network devices and terminal devices, wireless communication or charging between network devices, and wireless communication or charging between terminal devices. In the embodiments of this application, "communication" may also be described as "data transmission" or "information transmission". "Wireless charging" may also be simply referred to as "charging", "energy transfer", or "charging". Conversely, "charging" may also be described as "wireless energy transfer", "wireless charging", "wireless energy transmission", "radio frequency energy transmission", "radio frequency energy transfer", "radio frequency charging", or "radio frequency charging".

[0125] (6) In the embodiments of this application, "instruction" may include direct instruction and indirect instruction, as well as explicit instruction and implicit instruction. The information indicated by a certain piece of information (as described below, the instruction information) is called the information to be instructed. In the specific implementation process, there are many ways to indicate the information to be instructed, such as, but not limited to, directly indicating the information to be instructed, such as the information to be instructed itself or its index. It can also indirectly indicate the information to be instructed by indicating other information, where there is an association between the other information and the information to be instructed; or it can only indicate a part of the information to be instructed, while the other parts of the information to be instructed are known or pre-agreed upon. For example, the instruction can be implemented by using a pre-agreed (e.g., protocol predefined) arrangement order of various information, thereby reducing the instruction overhead to a certain extent. This application does not limit the specific method of instruction. It is understood that for the sender of the instruction information, the instruction information can be used to indicate the information to be instructed, and for the receiver of the instruction information, the instruction information can be used to determine the information to be instructed.

[0126] In this application, unless otherwise specified, the same or similar parts between the various embodiments can be referred to each other. In the various embodiments of this application, and the various methods / designs / implementations within each embodiment, unless otherwise specified or logically conflicting, the terminology and / or descriptions between different embodiments and between the various methods / designs / implementations within each embodiment are consistent and can be mutually referenced. The technical features in different embodiments and the various methods / designs / implementations within each embodiment can be combined to form new embodiments, methods, or implementations based on their inherent logical relationships. The following descriptions of the embodiments of this application do not constitute a limitation on the scope of protection of this application.

[0127] This application can be applied to long-term evolution (LTE) systems, new radio (NR) systems, or future communication systems beyond 5G. These communication systems include at least one network device and / or at least one terminal device.

[0128] Please see Figure 1A This is a schematic diagram of the architecture of the communication system used in the embodiments of this application. Figure 1A As shown, the communication system may include a radio access network 100, and optionally, the communication system may also include a core network 200 and an Internet 300. The RAN 100 includes at least one RAN node 110 (e.g., Figure 1A 110a and 110b, collectively referred to as 110, may also include at least one terminal device (such as...). Figure 1A RAN100, denoted as RAN100, comprises RAN nodes 120a-120j, collectively referred to as RAN120. RAN100 may also include other RAN nodes, such as wireless relay equipment and / or wireless backhaul equipment. Figure 1A (Not shown in the image). Terminal device 120 is wirelessly connected to RAN node 110, and RAN node 110 is wirelessly or wired connected to core network 200. The core network equipment in core network 200 and RAN node 110 in RAN 100 can be independent physical devices, or they can be the same physical device integrating the logical functions of core network equipment and RAN nodes. Terminal devices and RAN nodes can be interconnected via wired or wireless means.

[0129] The aforementioned communication system can be an O-RAN system, such as... Figure 1B As shown, the access network equipment communicates with the core network (CN) via a backhaul link and with terminal equipment via an air interface. The access network equipment includes a baseband unit (BBU) and a radio unit (RU). The BBU communicates with the CN via the backhaul link, and the RU communicates with at least one terminal device via the air interface. The BBU also communicates with at least one RU via a fronthaul link. The BBU and RU may or may not be co-located.

[0130] The BBU includes at least one control unit (CU) and at least one distributed unit (DU), which can communicate via at least one midhaul link.

[0131] The chip architectures of CU, DU, and RU can be found in [reference needed]. Figure 1C To understand. For example Figure 1CAs shown, the CU is a platform that performs upper-layer L2 and L3 functions. The Midhaul and Backhaul interfaces are used to carry traffic between the CU and DU, as well as between the CU and the core network. The DU performs L1 and some L2 functions, while the RU performs L1 computation and RF digital functions; the Fronthaul and Midhaul interfaces are used to carry traffic between the RU and DU, as well as between the CU and DU. If it is an integrated DU, then the integrated DU includes the aforementioned DU and RU functions.

[0132] The CU or DU hardware includes a chassis platform, motherboard, peripherals, and cooling system. The motherboard contains processing units, memory, internal I / O interfaces, and external connection ports. Its hardware accelerator is designed with interfaces, and hardware functional components include: storage for software, hardware, and system debugging interfaces, and a single-board management controller.

[0133] DU systems are typically implemented using multi-core processors and one or more hardware accelerators. Parts of the DU protocol stack can be implemented in software running on the multi-core processor, while computationally intensive L1 and L2 functions can be offloaded to hardware accelerators based on field-programmable gate arrays (FPGAs) or graphics processing units (GPUs); alternatively, all L1 functions can be offloaded to FPGA or GPU-based hardware accelerators, while other protocol stack components are implemented in software running on the processor; or the entire protocol stack can be implemented in software running on the processor. Hardware accelerators support interconnection with x86 or non-x86 processors. Similarly, accelerators have a multi-channel high-speed serial computer interconnect express (PCIe) interface pointing to the central processing unit (CPU) and external connections via Gigabit Ethernet (GbE) connections.

[0134] The RU consists of three parts: the O-RAN processing unit (OPU), the digital processing unit (DPU), and the O-RAN radio frequency processing unit (ORFDU).

[0135] The OPU receives enhanced common public radio interface (eCPRI) frames from the O-RAN fronthaul and performs fronthaul interface, bottom layer L1 (coding, scrambling, modulation, layer mapping, precoding), synchronization, beamforming, and resource unit mapping.

[0136] The OPU can be implemented as a CPU, FPGA, or application-specific integrated circuit (ASIC). The DPU is used to perform synchronization, digital downconversion (DDC) in the uplink (UL), digital upconversion (DUC) in the downlink (DL), peak-to-average ratio (PAPR) clipping (CFR), and digital pre-distortion (DPD). It improves power amplifier efficiency by reducing the peak-to-average power ratio (PAPR) or adjacent channel leakage ratio (ACLR) of the RF front end. The DPU can be implemented as an FPGA or ASIC.

[0137] The O-RU's RF processing unit (ORFDU) includes a transceiver module, up-converter, down-converter, power amplifier (PA), low-noise amplifier (LNA), transmission (Tx) filter, and receive (Rx) unit. The transceiver module performs conversions between the analog and digital domains, such as digital-to-analog converter (DAC) and analog-to-digital converter (ADC), RF sampling, RF usage in up-conversion and down-conversion, intermediate frequency (IF), and frequency conversion using a local oscillator (LO). It's important to note that the physical and logical partitions within the RF processing unit do not require specific boundaries.

[0138] The aforementioned communication system can be the Internet of Things (IoT). The IoT refers to the use of various information sensors, RFID technology, GPS, infrared sensors, laser scanners, and other devices and technologies to collect real-time information on objects or processes that need to be managed, connected, and interacted with. This information includes sound, light, heat, electricity, mechanics, chemistry, biology, and location data, and is accessed through various possible networks to achieve ubiquitous connectivity between things and between things and people, enabling intelligent perception, identification, and management of objects and processes. The IoT is an information carrier based on the internet, traditional telecommunications networks, etc., allowing all independently addressable ordinary physical objects to form an interconnected network.

[0139] The above-mentioned Internet of Things (IoT) takes the scenario of identifying information as an example, such as... Figure 1D As shown, access network devices can communicate with the Internet. For details on how access network devices communicate with the Internet, please refer to the previous sections. Figure 1A This section provides a brief overview. Access network devices can interact with terminal devices (such as...). Figure 1D The electronic tag in the network is used for wireless communication. During the wireless communication between the access network device and the terminal device, the terminal device can be wirelessly charged. Of course, the wireless charging process of this application is not limited to the network device charging the terminal device, but can also be the network device wirelessly charging the network device, or the terminal device wirelessly charging the terminal device.

[0140] The following description, in conjunction with the accompanying drawings, describes the communication process for wireless charging provided in the embodiments of this application. This communication process includes a first communication device and a second communication device. The first communication device can be a network device, a component or device applied to a network device (e.g., a processor, chip, or chip system), or a logic module or software capable of implementing all or part of the functions of the network device (e.g., a central unit (CU), a distributed unit (DU), or a radio unit (RU)). Alternatively, the first communication device can be a network device or a communication module within a network device, or a circuit or chip within a network device responsible for communication functions (e.g., a modem chip, also known as a baseband chip, or a system-on-a-chip (SoC) chip containing a modem core, or a system-in-package (SIP) chip). Of course, the first communication device can also be a terminal device, a component or device applied to a terminal device (e.g., a processor, chip, or chip system), or a logic module or software capable of implementing all or part of the functions of the terminal device. Alternatively, the first communication device is a terminal device or a communication module in a terminal device, or a circuit or chip in a terminal device that is responsible for communication functions (such as a modem chip, also known as a baseband chip, or a system-on-chip (SoC) chip or system-in-package (SIP) chip containing a modem core).

[0141] like Figure 2 As shown, the communication method provided in this application embodiment includes:

[0142] S201. The first communication device sends a first request to the second communication device. Correspondingly, the second communication device receives the first request from the first communication device.

[0143] The first request includes first information and second information. The first information is used to indicate the wireless charging mode, and the second information includes information related to the wireless charging mode.

[0144] In this application, the first request can be a query request sent by the reader of the electronic tag to the electronic tag. Of course, the first request can also be other types of requests or messages, and this application does not limit it.

[0145] In this application, the first information can be indication information that indicates different content through a bit sequence formed by one or more bits. The first information is used to indicate a wireless charging mode, and there can be one or more wireless charging modes. When there are multiple modes, different bit sequences can correspond to different wireless charging modes, and different wireless charging modes correspond to different wireless charging procedures.

[0146] In this application, the second information may include one or more pieces of information (also referred to as parameters), which can be understood as indication information of specific content related to the wireless charging mode. "Related" means that the second information corresponding to different wireless charging modes may be the same or different, where different includes partial or complete differences. Furthermore, the number of pieces of information related to different wireless charging modes may be different. For example, there may be 5 pieces of information related to wireless charging mode 1 and 7 pieces of information related to wireless charging mode 2, and 5 of these 7 pieces of information may be the same as the 5 pieces of information related to wireless charging mode 1. Of course, these 5 pieces of information may also be partially the same or completely different.

[0147] For an understanding of the relationship between the first and second pieces of information, please refer to Table 1.

[0148] Table 1

[0149]

[0150] In Table 1, field 1 corresponds to the first information. Table 1 illustrates how the first information is represented by a bit sequence of A bits. Different values ​​of this bit sequence can indicate different wireless charging modes. For example, if A = 4, there will be 16 values: 0000, 0001, 0010, 0011, 0100, 0101, 0110, 0111, 1000, 1001, 1010, 1011, 1100, 1101, 1110, and 1111. Each value can indicate a different wireless charging mode. Of course, if there are fewer than 16 wireless charging modes, the value of A can be smaller. If there are two wireless charging modes, A can be equal to 1, using a bit "0" to indicate one mode and a bit "1" to indicate the other. If there are more than 16 wireless charging modes, the value of A can be larger. The specific value of A can be set according to requirements.

[0151] In Table 1, the information corresponding to field 2 and field 3 both belong to the second type of information. If other fields are included, the information corresponding to those other fields also belongs to the second type of information. The information corresponding to field 2 can be represented by B bits to indicate information 1 related to the wireless charging mode, and the information corresponding to field 3 can be represented by C bits to indicate information 2 related to the wireless charging mode.

[0152] A, B, and C can all be positive integers.

[0153] Taking the communication scenario between the tag reader and the electronic tag as an example, in this communication scenario, the first request may include the content shown in Table 2 below.

[0154] Table 2:

[0155]

[0156] In Table 2, the command field can be the field corresponding to the first information. Different bit sequences of the 4 bits indicate different meanings. For example, 1000 in Table 2 can indicate the disk storage communication mode, used to indicate disk storage management. The other fields after command, such as DR, M, TRext, Sel, Session, Target, Q, and CRC fields, can all be called the second information. Among them, the bit value of the DR field indicates the value of the DR register, where 0 indicates DR=8, and 1 indicates DR=64 / 3; the bit value of the M field indicates the value of M, such as 00 indicates M=1, 01 indicates M=2, 10 indicates M=4, and 11 indicates M=8. The bit value of the TRext field indicates whether the pilot tone is used, such as 0 indicates no pilot tone, and 1 indicates pilot tone is used. The bit value of the Sel field indicates the selection range, such as 00 indicates all, 01 also indicates all, 10 indicates a specified portion, and 11 indicates a non-specified portion. The Session field's bit values ​​represent different session modes, such as: 00 for session mode S0, 01 for session mode S1, 10 for session mode S2, and 11 for session mode S3. The Target field's bit values ​​represent different targets, such as: 0 for target A and 1 for target B. The Q field's bit values ​​represent the tag's slot count, with 4 bits representing slot counts from 0 to 15. The Cyclic Redundancy Check (CRC) field's bit values ​​represent the CRC-5 algorithm, indicating that cyclic redundancy verification is performed using the CRC-5 algorithm.

[0157] Under different wireless charging modes, the relationship between the first information and the second information in the first request can be represented as shown in Table 3 or Table 4.

[0158] Table 3:

[0159]

[0160] In Table 3, field 1 indicates wireless charging mode 1 using A bits. If wireless charging is accomplished using a query request in the communication scenario between the tag reader and the electronic tag, then field 1 can be a command field, with A bits equal to 4. The first information can be 1110, indicating wireless charging mode 1. Of course, it can also be indicated by a bit sequence other than the bit sequence 1000 already occupied by the storage communication mode; the bit sequence 1110 here is just an example. The second information can include one or more pieces of information. For example, field 2 can indicate the beam scan start time using X bits. For example, time indicator 1 can indicate the time when beam scanning begins. The start time of beam scanning can be calculated from time indicator 1, which can be a time offset, such as offset from one or more slots or sub-slots. Field 3 can indicate open-loop or closed-loop using one bit, such as using 0 to indicate open-loop and 1 to indicate closed-loop. Open-loop beam scanning refers to a scanning type that does not require feedback of measurement results for one or more beams from a second communication device. It can also be understood as a beam scanning type that directly collects energy from one or more beams for wireless charging. Closed-loop beam scanning refers to a scanning type that requires feedback of measurement results for one or more beams from a second communication device. Of course, the second information in Table 3 may also include other information, such as at least one of the following: the number of transmitted beams, the duration of each beam scan, or the end time of each beam scan.

[0161] If Table 3 uses the query format of a communication scenario between a tag reader and an electronic tag as an example, the first piece of information can use the idle bit sequence of the command field to indicate the wireless charging mode. When the indication function of the command field changes, the other fields in the query need to change accordingly. Specifically, field 2 indicates the beam scan start time, which can be set to the ST field (an abbreviation of start time), and field 3 indicates the open-loop or closed-loop beam scan type, which can be set to the Ring field. Of course, this is merely an illustrative example and does not limit the specific representation of fields 2 and 3.

[0162] Table 4:

[0163]

[0164] In Table 4, field 1 indicates wireless charging mode 2 through A fields. If wireless charging is completed using a query request in the communication scenario between the tag reader and the electronic tag, then field 1 can be a command field, the number of bits A can be equal to 4, and the first information can be 1111, indicating wireless charging mode 2. Of course, wireless charging mode 2 can also be indicated by a bit sequence other than the bit sequence 1000 already occupied by the storage communication mode. The bit sequence 1111 here is just an example. The second information can include one or more pieces of information. The second information corresponding to different wireless charging modes can be the same or different. Different scenarios will be further introduced in subsequent embodiments.

[0165] While the relationship between the first and second information was described in Tables 3 and 4 above using the query structure of the communication scenario between the tag reader and the electronic tag, this application is not limited to the communication scenario between the tag reader and the electronic tag. In other communication scenarios, additional signaling or existing signaling can be used to implement the content described in Tables 1, 3 and 4 above.

[0166] S202. The first communication device transmits a beam. Correspondingly, the second communication device receives the beam.

[0167] S203. The second communication device charges itself according to the first information and the second information in a wireless charging mode.

[0168] In this application, the process of charging according to the wireless charging mode based on the first information and the second information refers to determining the charging procedure according to the wireless charging mode indicated by the first information, and completing the charging process according to the specific content of one or more pieces of information in the second information. Charging refers to collecting energy from the beam for charging, or measuring the beam, determining the beam that meets the charging requirements among multiple beams (e.g., the optimal beam), notifying the first communication device to send the corresponding beam (e.g., the optimal beam), and then collecting energy from the corresponding beam for charging.

[0169] The communication method provided in this application involves a first communication device sending a first request to a second communication device. The first and second information in the first request indicate a wireless charging mode and related information. The second communication device can then perform beam scanning on the beam transmitted by the first communication device based on the first and second information to complete wireless charging. This eliminates the need for either the second or first communication device to send a reference signal related to channel measurement in advance, and also eliminates the need for the first communication device to perform channel estimation and precoding based on the reference signal. This saves energy consumed by either the second or first communication device in transmitting the reference signal, conserves transmission resources for the reference signal, and reduces the complexity of channel estimation and precoding performed by the first communication device based on the reference signal. Furthermore, not all second communication devices possess channel measurement capabilities; therefore, the wireless charging process provided in this application expands the range of second communication devices capable of wireless charging.

[0170] The aforementioned communication scheme for wireless charging may include multiple different implementation processes. These different implementation processes are related to the content indicated by the first information and the content contained in the second information, which will be described separately below.

[0171] First, the first information is used to indicate the wireless charging mode for activating beam scanning, and the second information includes the time when the first communication device starts beam scanning and the type of open-loop beam scanning.

[0172] like Figure 3 As shown, the communication methods in this situation include:

[0173] S301. The first communication device sends a first request to the second communication device. Correspondingly, the second communication device receives the first request from the first communication device.

[0174] The first information is used to indicate the wireless charging mode for activating beam scanning, and the second information includes the time when the first communication device starts beam scanning and the type of open-loop beam scanning.

[0175] Of course, the second information may also include at least one of the following: the number of beams transmitted by the first communication device, the duration of each beam scan, or the end time of each beam scan.

[0176] The first request in this case can be understood by referring to Table 5.

[0177] Table 5:

[0178]

[0179] In Table 5, the first information corresponding to field 1 can indicate wireless charging mode 1. Wireless charging mode 1 can be a wireless charging mode with activated beam scanning. Wireless charging mode with activated beam scanning refers to activating the scanning function of one or more beams sent by the first communication device.

[0180] The meanings and functions of fields 2 and 3 can be understood by referring to the introduction in Table 3. Field 4 can be used to indicate the number of beams transmitted by the first communication device. For example, in Table 5, a bit sequence of P bits indicates the number of beams. If P = 4 and the bit sequence is 0011, it indicates that there are 4 beams. Field 5 can be used to indicate the duration of each beam scan. For example, in Table 5, the duration of a beam scan is indicated by Y bits. Field 6 can be used to indicate the end time of each beam scan. For example, in Table 5, the end time is indicated by Z bits. For example, the end time of a beam scan is indicated by time indicator 2, and the end time of the beam scan can be calculated from time indicator 2. Only one of fields 5 or 6 can be included. If field 5 is included, the start time of the beam scan can be calculated from time indicator 1 in field 2, and the end time can be calculated from the beam scan duration in field 5. If field 5 is included, the end time of the beam scan can be calculated from time indicator 2 in field 6.

[0181] If the start time of beam scanning is represented by t1, the end time of beam scanning by t2, and the duration of beam scanning by L, then the relationship between the three is t2 = t1 + L.

[0182] Table 5 uses the example of the second information including multiple pieces of information to illustrate the point. In reality, the second information can also include some of the information in Table 5.

[0183] The first communication device can determine, based on the first request, to activate the beam scanning function according to the first information.

[0184] S302. The first communication device transmits a beam.

[0185] S303. The second communication device collects energy from the beam emitted by the first communication device for charging after the first communication device starts beam scanning, based on the time when the first communication device starts beam scanning and the type of open-loop beam scanning.

[0186] Of course, if the second information also includes other information, such as the number of beams, the first communication device will collect energy from the corresponding number of beams for charging. If the second information also includes the duration of beam scanning, the first communication device will collect energy from the beams for charging within that duration.

[0208] In this application, the first feedback information can be represented in the form shown in Table 7 below.

[0209] Table 7

[0210]

[0211] Table 7 lists the cases where a 16-bit random number (RN) is used to indicate the first feedback information. In Table 7, RN(0-7) indicates that the first 8 bits are used to indicate the identifier of the terminal device, and RN(8-15) indicates that the last 8 bits are used to indicate the index of the beam, such as the index of the target beam.

[0222] The first request in this case can be understood by referring to Table 8.

[0223] Table 8:

[0224]

[0225] The difference between Table 8 and Table 6 is that the first indication information in field 1 indicates wireless charging mode 2, which means that the wireless charging mode with beam feedback is activated, requiring a second communication device to provide feedback on the measurement results of one or more beams. The other fields are the same as in Table 6; please refer to the description in Table 6 for further understanding.

[0243] Table 9:

[0244]

[0245] Table 9 differs from Table 8 in that it adds fields 7 and 8. Field 7 uses G bits to indicate the time-domain resources for feedback, such as sending the first feedback information in the time domain indicated by the time-domain indication information. Field 8 uses H bits to indicate the frequency-domain resources for feedback, such as sending the first feedback information in the frequency-domain resources indicated by the frequency-domain resource indication information.

[0246] It should be noted that in the embodiments of this application, X, Y, Z, P, G, and H are all positive integers, and the number of bits for each field listed in Tables 1 to 9 is merely an example and should not be construed as a limitation on the number of bits for each field. Furthermore, the meaning of each field described in the information description can also be expressed in other forms and is not limited to the forms listed in Tables 1 to 9 of this application.

The second communication device measures the energy in the beam emitted by the first communication device after the first communication device starts beam scanning, based on the time when the first communication device starts beam scanning and the type of closed-loop beam scanning, in order to determine the first feedback information.

[0250] S605. The second communication device sends the first feedback information to the first communication device based on at least one of the time-domain resources or frequency-domain resources of the first feedback information. Correspondingly, the first communication device receives the first feedback information based on at least one of the time-domain resources or frequency-domain resources of the first feedback information.

[0251] S606. The first communication device transmits the target beam according to the first feedback information. Correspondingly, the second communication device receives the target beam.

[0252] S607. The second communication device collects energy from the target beam for recharging.

[0253] In the solution provided in this application embodiment, when the first information indicates the activation of the wireless charging mode with beam feedback, and the second information includes an open-loop beam scanning type, the second communication device will measure the beam sent by the first communication device after the first communication device sends the beam to determine the first feedback information, such as the beam with the best charging capability or charging effect. This allows the first communication device to subsequently perform more efficient wireless charging on the second communication device based on the first feedback information. Furthermore, the second information may also include feedback time or feedback resources. This eliminates the need for the first communication device to send a third request to the second communication device to complete the feedback of the first feedback information, reducing the occupation of transmission resources required to instruct the first feedback information.

[0254] The communication method described in this application can also be applied to O-RAN systems. For example... Figure 7 As shown, the communication methods in an O-RAN system include:

[0264] The RU can perform down-conversion processing on the feedback information before sending it to the DU.

[0265] S707.DU sends feedback information to CU. Correspondingly, CU receives the feedback information.

[0266] The DU can perform baseband processing on the received feedback information and transmit the processed feedback information to the CU through the mid-band link.

[0267] In this application, the CU can continue to scan the next beam, repeating the steps S702 to S707 above, until the specified number of iterations is reached, and the CU will eventually obtain the optimal beam.

[0268] The optimal beam here can also be replaced with the optimal frequency, or it can be both the optimal beam and the optimal frequency.

[0269] Based on the optimal beam information, S708.CU instructs DU to notify RU to wirelessly charge the terminal device.

[0270] Of course, the CU can also return the optimal beam to the core network. Alternatively, the CU can choose not to return specific scanning information to the core network, but directly return an indication that the scan is complete; or it can choose not to return any information to the core network devices and directly charge the terminal based on the optimal frequency and / or optimal beam.

[0271] In this application, if the core network receives the optimal beam information from the CU, the core network can send a charging command to the CU based on the optimal beam fed back by the CU. After receiving the charging command, the CU transmits a charging signal through the mid-haul and front-haul by the RU to charge the terminal equipment.

[0276] In this application, the CU includes CPUs based on x86 architecture or advanced reduced instruction set computer (ARM) architecture, as well as chips of the FPGA / GPU / other accelerator types. The x86 type chip or the ARM-based chip processes instructions from the core network. Some logical operations involved, such as simple summation, are handled by the FPGA / GPU / other accelerator. After processing, the results are fed back to the CPU, which then performs further control operations, such as determining whether to send control instructions to the DU. The interface between the CPU and the FPGA / GPU / other accelerator can be PCIe.

[0277] Of course, S801 can also be skipped, and the beam scanning command can be sent directly by the CU.

[0279] In this application, the DU also includes CPUs based on x86 or ARM architectures, as well as chips of various types such as FPGAs / GPUs / other accelerators. The x86-type chips or ARM-based chips process the request instructions from the CU. Some of the underlying logical operations, such as simple summation, are handled by the FPGA / GPU / other accelerators. After processing, the results are fed back to the CPU, which then performs further control operations, such as determining whether to send control instructions to the RU. The interface between the CPU and the FPGA / GPU / other accelerators can be PCIe.

[0280] The S803.DU sends a beam scanning command to the RU via the fronthaul link. Correspondingly, the RU receives the beam scanning command.

[0281] In this application, the RU includes a fronthaul processing unit for processing instruction signaling from the DU. The fronthaul processing unit can be a CPU or a dedicated chip, such as an FPGA / ASIC type chip. The fronthaul processing chip schedules the digital signal processing module to process signals from the RF processing module based on the instructions of the DU. The digital signal processing module performs operations including fast fourier transform (FFT), modulation and demodulation, etc. The RF processing chip mainly handles down-conversion, spectrum splicing / shifting operations, and sends the processing results to the digital processing chip.

[0282] The S804.RU sends a beam to the terminal device. Correspondingly, the terminal device receives the beam.

[0283] The radio frequency unit will perform beam scanning, polling each frequency point and each beam.

[0284] S805. The terminal device sends feedback information to the RU. Correspondingly, the RU receives the feedback information.

[0285] The feedback information can be as described above. Figure 3 The feedback information used to indicate the charging result described in the embodiments can also be the above-mentioned... Figures 4 to 7 The first feedback information presented.

[0286] S806.RU sends feedback information to DU. Correspondingly, DU receives the feedback information.

[0287] The RU can perform down-conversion processing on the feedback information before sending it to the DU.

[0288] S807.DU sends feedback information to CU. Correspondingly, CU receives the feedback information.

[0289] The DU can perform baseband processing on the received feedback information and transmit the processed feedback information to the CU through the mid-band link.

[0290] In this application, the CU can continue to scan the next beam, repeating the steps S702 to S707 above, until the specified number of iterations is reached, and the CU will eventually obtain the optimal beam.

[0291] The optimal beam here can also be replaced with the optimal frequency, or it can be both the optimal beam and the optimal frequency.

[0292] Based on the optimal beam information, S808.CU instructs DU to notify RU to wirelessly charge the terminal device.

[0293] Of course, the CU can also return the optimal beam to the core network. Alternatively, the CU can choose not to return specific scanning information to the core network, but directly return an indication that the scan is complete; or it can choose not to return any information to the core network devices and directly charge the terminal based on the optimal frequency and / or optimal beam.

[0294] In this embodiment, the access network device utilizes the collaboration between different chips. For example, the CPU primarily controls logic decisions, the accelerator handles simple parallel calculations, and the digital processing chip specializes in digital signal processing, which improves efficiency. This chip-to-chip cooperation enables a highly efficient beam scanning process, thereby enhancing power transfer efficiency.
