[0112] In different systems, the CU (or CU-CP and CU-UP), the DU, or the RU can also have different names, but those skilled in the art can understand their meanings.

[0120] (3) The terms "system" and "network" in the embodiments of the present application can be used interchangeably. "Multiple" means two or more. "And / or" describes the association relationship of the associated objects, which means that there can be three relationships, for example, A and / or B can represent the following three cases: A exists alone, A and B exist together, and B exists alone, where A and B can be singular or plural. The character " / " generally represents an "or" relationship between the associated objects. "At least one of the following" or similar expressions means any combination of these items, including any combination of single or multiple items. For example, "at least one of A, B, and C" includes A, B, C, AB, AC, BC, or ABC. In addition, unless otherwise specified, the ordinal numbers "first", "second", etc. mentioned in the embodiments of the present application are used to distinguish multiple objects, and are not used to limit the order, time sequence, priority or importance of the multiple objects.

[0121] (4) In the embodiments of the present application, "sending" and "receiving" represent the direction of signal transmission. For example, "sending information to XX" can be understood as that the destination of the information is XX, which can include direct sending through the air interface, or indirect sending through the air interface by other units or modules. "Receiving information from YY" can be understood as that the source of the information is YY, which can include direct receiving from YY through the air interface, or indirect receiving from YY through the air interface by other units or modules. "Sending" can also be understood as the "output" of the chip interface, and "receiving" can also be understood as the "input" of the chip interface.

[0122] In other words, sending and receiving can be between devices, such as between network devices and terminal devices, or within devices, such as between components, modules, chips, software modules or hardware modules within a device through a bus, wire or interface.

[0123] It can be understood that the information may be processed as necessary between the source and the destination of the information transmission, such as encoding and modulation, but the destination can understand the valid information from the source. Similar expressions in the present application can be similarly understood, and will not be repeated here.

The information indicated by certain information (indication information described below) is referred to as to-be-indicated information. In the specific implementation process, there are many ways to indicate the to-be-indicated information, for example, but not limited to, the to-be-indicated information can be directly indicated, such as the to-be-indicated information itself or the index of the to-be-indicated information. The to-be-indicated information can also be indirectly indicated by indicating other information, where the other information and the to-be-indicated information have an association relationship. The to-be-indicated information can also be indicated only by a part, and the other part of the to-be-indicated information is known or agreed in advance. For example, the indication of a specific information can be achieved by means of the arrangement order of each information agreed in advance (for example, protocol predefined), thereby reducing the indication overhead to a certain extent. The present application does not limit the specific manner of indication. It can be understood that the indication information can be used to indicate the to-be-indicated information for the sender of the indication information, and the indication information can be used to determine the to-be-indicated information for the receiver of the indication information.

In the various embodiments of the present application, and the various methods / designs / implementation manners in each embodiment, the terms and / or descriptions of different embodiments, and the various methods / designs / implementation manners in each embodiment are consistent and can be mutually referred to, unless otherwise specified and logically conflicted. The technical features of different embodiments, and the various methods / designs / implementation manners in each embodiment can be combined to form new embodiments, methods, or implementation manners according to their inherent logical relationship. The implementation manners of the present application described below do not constitute a limitation on the protection scope of the present application.

[0127] The present application can be applied to a long term evolution (LTE) system, a new radio (NR) system, or a future communication system after 5G. The communication system includes at least one network device and / or at least one terminal device.

[0128] Referring to FIG. 1A, a schematic diagram of an architecture of a communication system to which embodiments of the present application are applied is shown. As shown in FIG. 1A, the communication system can include a radio access network 100, and optionally, the communication system can further include a core network 200 and an Internet 300. The RAN 100 includes at least one RAN node 110 (e.g., 110a and 110b in FIG. 1A, collectively referred to as 110) and at least one terminal device (e.g., 120a-120j in FIG. 1A, collectively referred to as 120). The RAN 100 can further include other RAN nodes, such as a wireless relay device and / or a wireless backhaul device (not shown in FIG. 1A). The terminal devices 120 are wirelessly connected with the RAN nodes 110, and the RAN nodes 110 are connected with the core network 200 through wire or wireless. The core network devices in the core network 200 and the RAN nodes 110 in the RAN 100 can be independent and different physical devices, or can be the same physical device integrated with the logical functions of the core network devices and the logical functions of the RAN nodes. The terminal devices and the terminal devices, and the RAN nodes and the RAN nodes can be connected with each other through wire or wireless.

[0129] The above communication system can be an O-RAN system. As shown in FIG. 1B, the access network device communicates with the core network (CN) through a backhaul link, and communicates with the terminal device through an air interface. The access network device includes a baseband unit (BBU) and a radio unit (RU). The BBU communicates with the CN through the backhaul link, and the RU communicates with at least one terminal device through the air interface. The BBU communicates with at least one RU through a front-haul link. The BBU and the RU can be co-located or not.

[0130] The BBU includes at least one control unit (CU) and at least one distributed unit (DU). The CU and the DU can communicate through at least one mid-haul link.

[0131] The chip architecture of the CU, the DU and the RU can be understood with reference to FIG. 1C. As shown in FIG. 1C, the CU is a platform that performs upper layer L2 and L3 functions. The mid-haul interface and the backhaul interface are used to carry traffic between the CU and the DU, and between the CU and the core network. The DU performs L1 and part of L2 functions, and the RU performs L1 computation and radio frequency digital part functions. The front-haul interface and the mid-haul interface are used to carry traffic between the RU and the DU, and between the CU and the DU. If the DU is integrated, the integrated DU includes the above-mentioned DU and RU functions.

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

[0133] The DU system is usually implemented using a multi-core processor and one or more hardware accelerators. Part of the DU protocol stack can be implemented in software running on the multi-core processor, and the computationally intensive L1 and L2 functions can be offloaded to hardware accelerators based on field-programmable gate arrays (FPGAs) or graphic processing units (GPUs); or all L1 functions are offloaded to hardware accelerators based on FPGAs or GPUs, while other protocol stack contents are implemented in software running on the processor; or all the protocol stack is implemented in software running on the processor. The hardware accelerator supports interconnection with an x86 or non-x86 processor. Similarly, the accelerator has a multi-lane peripheral component interconnect express (PCIe) interface pointing to a central processing unit (CPU), and is externally connected through a gigabit Ethernet (GbE) connection.

[0134] The RU includes three parts: an O-RAN processing unit (OPU), a digital processing unit (DPU), and an 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 the fronthaul interface, the lowest layer L1 (encoding, 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 down convert (DDC) in uplink (UL), digital up convert (DUC) in downlink (DL), crest factor reduction (CFR) and digital pre-distortion (DPD) to improve power amplifier efficiency by reducing the peak to average power ratio (PAPR) or adjacent channel leakage ratio (ACLR) of the radio frequency front end; the DPU can be implemented as an FPGA or ASIC.

[0137] The RF processing unit (ORFDU) of the O-RU includes a transceiver module, an upconverter, a downconverter, a power amplifier (PA), a low noise amplifier (LNA), a transmission (Tx) filter and a receive (Rx). The transceiver module is used to perform conversion between the analog domain and the digital domain, such as digital to analog conversion (DAC) and analog to digital conversion (ADC), RF sampling, frequency conversion using RF in upconversion and downconversion, intermediate frequency (IF), and local oscillator (LO) mixing for frequency conversion. It should be noted that the physical and logical partitions within the RF processing unit do not require specific boundaries.

[0138] The communication system can be an Internet of Things (IoT), which refers to real-time collection of objects or processes that need to be managed, connected, and interacted through various information sensors, radio frequency identification technology, global positioning systems, infrared sensors, laser scanners, and other devices and technologies, collecting various information such as sound, light, heat, electricity, mechanics, chemistry, biology, and location, and achieving ubiquitous connection of objects and people through various possible network access, and achieving intelligent perception, identification, and management of objects and processes. The Internet of Things is an information carrier based on the Internet, traditional telecommunications network, etc., allowing all ordinary physical objects that can be independently addressed to form an interconnected network.

[0139] The Internet of Things takes the scenario of identifying information as an example, as shown in FIG. 1D, the access network device can communicate with the Internet, and the way in which the access network device communicates with the Internet can be understood with reference to the foregoing introduction in FIG. 1A. The access network device can perform wireless communication with a terminal device (such as the electronic tag in FIG. 1D). In the process of 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 the present application is not limited to charging the terminal device by the network device, but can also be wireless charging of the network device by the network device, or wireless charging of the terminal device by the terminal device.

[0140] The communication process provided by the embodiments of the present application can be used for wireless charging. The 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 (e.g., a processor, a chip, or a chip system) applied to the network device, or a logic module or software (e.g., a central unit (CU), a distributed unit (DU), or a radio unit (RU)) capable of implementing all or part of the functions of the network device. Alternatively, the first communication device can be a network device or a communication module in the network device, or a circuit or chip (e.g., a modem chip, also known as a baseband chip, or a system on chip (SoC) chip or a system in package (SIP) chip containing a modem core) responsible for the communication function in the network device. Of course, the first communication device can also be a terminal device, a component or device (e.g., a processor, a chip, or a chip system) applied to the terminal device, or a logic module or software capable of implementing all or part of the functions of the terminal device. Alternatively, the first communication device can be a terminal device or a communication module in the terminal device, or a circuit or chip (e.g., a modem chip, also known as a baseband chip, or a system on chip (SoC) chip or a system in package (SIP) chip containing a modem core) responsible for the communication function in the terminal device.

[0141] As shown in FIG. 2, the communication method provided by the embodiments of the present application includes the following steps.

[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 a wireless charging mode, and the second information includes information related to the wireless charging mode.

[0144] In the present application, the first request can be a query request sent by a reader of an electronic tag to the electronic tag. Of course, the first request can also be other types of requests or messages, which are not limited in the present application.

[0145] In the present application, the first information can be indication information indicating different contents in the form of a bit sequence formed by one bit or multiple bits. The first information is used to indicate a wireless charging mode, which can be one or more. When there are multiple wireless charging modes, different bit sequences can correspond to different wireless charging modes, and different wireless charging modes correspond to different wireless charging processes.

[0146] In the present application, the second information can include one or more information (also referred to as parameters), which can be understood as indication information of specific contents related to the wireless charging mode. "Related" means that the second information corresponding to different wireless charging modes can be the same or different, where different includes partial or complete difference. Moreover, the number of information related to different wireless charging modes can be different, for example, the information related to wireless charging mode 1 has 5, and the information related to wireless charging mode 2 has 7, of which 5 information can be the same as the 5 information related to wireless charging mode 1. Of course, the 5 information can also be partially the same, or all different.

[0147] For the relationship between the first information and the second information, please refer to Table 1-2 for understanding.

[0148] Table 1-2

[0149] In Table 1-2, the information corresponding to field 1 can be the first information, and the example shown in Table 1-2 is to represent the first information by a bit sequence of A bits. Different values of the bit sequence can indicate different wireless charging modes, for example, if A = 4, there will be 0000, 0001, 0010, 0011, 0100, 0101, 0110, 0111, 1000, 1001, 1010, 1011, 1100, 1101, 1110 and 1111, of which each value can indicate a different wireless charging mode. Of course, if there are not 16 wireless charging modes, A can have a smaller value, for example, if there are two wireless charging modes, A can be equal to 1, and only one bit "0" is needed to indicate one wireless charging mode, and one bit "1" is needed to indicate one wireless charging mode. If there are more than 16 wireless charging modes, A can have a larger value, and the specific value of A can be set according to the demand.

[0150] In Table 1-2, the information corresponding to field 2 and the information corresponding to field 3 both belong to the second information. If there are other fields, the information corresponding to the other fields also belongs to the second information. The information corresponding to field 2 can indicate information 1 related to the wireless charging mode by B bits, and the information corresponding to field 3 can indicate information 2 related to the wireless charging mode by C bits.

[0151] A, B, and C can be positive integers.

[0152] Taking a communication scenario of a tag reader and an electronic tag as an example, the first request can include the content shown in Table 2.

[0153] Table 2:

[0154] In Table 2, the command field (command) can be a field corresponding to the first information. Different bit sequences of 4 bits indicate different meanings, such as: 1000 in Table 2 can indicate an inventory communication mode, which is used to indicate inventory management. The information corresponding to other fields after the command, such as: DR, M, TRext, Sel, Session, Target, Q, and CRC fields, can be referred to as second information. Among them, the bit value of the DR field represents the value of the DR register, wherein 0 represents DR = 8, and 1 represents DR = 64 / 3; the bit value of the M field represents the value of M, such as: 00 represents M = 1, 01 represents M = 2, 10 represents M = 4, and 11 represents M = 8. The bit value of the TRext field represents whether a pilot tone is used, such as: 0 represents no pilot tone, and 1 represents use of a pilot tone. The bit value of the Sel field represents a selected range, such as: 00 represents selection of all, 01 also represents selection of all, 10 represents selection of a specified part, and 11 represents selection of a non-specified part. The bit value of the Session field represents different session modes, such as: 00 represents session mode S0, 01 represents session mode S1, 10 represents session mode S2, and 11 represents session mode S3. The bit value of the Target field represents a corresponding target, such as: 0 represents a corresponding target A, and 1 represents a corresponding target B. The bit value of the Q field represents a time slot count value of a tag, and 4 bits represent a time slot count value from 0 to 15. The bit value corresponding to the cyclic redundancy check (CRC) field represents a CRC-5 algorithm, that is, a cyclic redundancy check is performed using the CRC-5 algorithm.

[0155] In different wireless charging modes, the relationship between the first information and the second information in the first request can be represented in the form of Table 3 or Table 4.

[0156] Table 3:

[0157] In Table 3, field 1 indicates wireless charging mode 1 by A fields, if wireless charging is completed by a query request (query) of a communication scenario of a tag reader and an electronic tag, field 1 can be a command field, the number of bits A can be equal to 4, the first information can be 1110, which can indicate wireless charging mode 1. Of course, wireless charging mode 1 can also be indicated by other bit sequences except the bit sequence 1000 occupied by the inventory communication mode. The bit sequence 1110 here is only an example. The second information can include one or more information, such as: field 2 can indicate the beam scanning start time by X bits, such as: time indication 1 can indicate the time to start beam scanning. The time to start beam scanning can be calculated by time indication 1. Time indication 1 can be a time offset, such as: offset by one or more time slots, sub-slots, etc. Field 3 can indicate open loop or closed loop by 1 bit, such as: 0 indicates open loop, and 1 indicates closed loop. The open loop beam scanning type refers to a scanning type that does not require the second communication device to feed back the measurement result of one or more beams. It can also be understood that the open loop beam scanning type is a beam scanning type that directly collects energy from one or more beams for wireless charging. The closed loop beam scanning type refers to a scanning type that requires the second communication device to feed back the measurement result of one or more beams. Of course, the second information in Table 3 can also include other information, such as: at least one of the number of transmitted beams, the time length of each beam scanning, or the end time of each beam scanning.

[0158] If Table 3 is used as an example to illustrate the format of the query request (query) of the communication scenario of the tag reader and the electronic tag, the first information can indicate wireless charging mode by borrowing the idle bit sequence of the command field. When the indication function of the command field changes, other fields on the query need to change accordingly. Among them, field 2 indicates the beam scanning start time, which can be set as the ST field, i.e., the acronym of start time. Field 3 indicates the open loop or closed loop beam scanning type, which can be set as the Ring field. Of course, this indicates an exemplary description, and does not limit the specific representation form of field 2 and field 3.

[0159] Table 4:

[0160] In Table 4, field 1 indicates wireless charging mode 2 by A fields, if wireless charging is completed by a query request (query) of a communication scenario of a tag reader and an electronic tag, field 1 can be a command field, the number of bits A can be equal to 4, the first information can be 1111, which can indicate wireless charging mode 2. Of course, wireless charging mode 2 can also be indicated by other bit sequences other than the bit sequence 1000 occupied by the inventory communication mode. The bit sequence 1111 here is only an example. The second information can include one or more 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.

[0161] In the above introduction of Table 3 and Table 4, although the relationship between the first information and the second information is introduced by using the structure of the query of the communication scenario of the tag reader and the electronic tag, the present application is not limited to the communication scenario of the tag reader and the electronic tag. In other communication scenarios, new signaling can be added or existing signaling can be used to realize the contents introduced in Table 1-1, Table 1-2, Table 3 and Table 4.

[0162] S202. The first communication device transmits a beam. Correspondingly, the second communication device receives the beam.

[0163] S203. The second communication device charges according to the wireless charging mode according to the first information and the second information.

[0164] In the present application, the process of charging according to the wireless charging mode according to 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. Charging refers to collecting energy in the beam for charging, or measuring the beam to determine the beam (such as the optimal beam) that meets the charging requirement in multiple beams, notifying the first communication device to transmit the corresponding beam (such as the optimal beam), and then collecting energy from the corresponding beam for charging.

[0165] The communication method provided by the embodiments of the present application, the first communication device sends a first request to the second communication device, the first information and the second information in the first request are used to indicate a wireless charging mode and information related to the wireless charging mode, and the second communication device can perform beam scanning on the beam sent by the first communication device according to the first information and the second information, and complete wireless charging. The second communication device or the first communication device does not need to send a reference signal related to channel measurement to the other party in advance, and the first communication device does not need to perform channel estimation and precoding according to the reference signal to complete wireless charging. In this way, the power consumed by the second communication device or the first communication device due to the transmission of the reference signal is saved, the transmission resource for transmitting the reference signal is saved, and the complexity of the first communication device performing channel estimation and precoding according to the reference signal is reduced. Moreover, not all second communication devices have channel measurement capability, and therefore, the wireless charging process provided by the present application also expands the types of second communication devices that can perform wireless charging.

[0166] The above communication scheme for wireless charging can include a plurality of different implementation processes, which are related to the content indicated by the first information and the content contained in the second information, which will be introduced below.

[0169] 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.

[0170] The first information is used to indicate a wireless charging mode in which beam scanning is activated, and the second information includes a time at which the first communication device starts to perform beam scanning and an open-loop beam scanning type.

[0171] Of course, the second information can also include at least one of the number of beams transmitted by the first communication device, the time length of each beam scanning, or the end time of each beam scanning.

[0172] The first request in this case can be understood with reference to Table 5.

[0174] In Table 5, the first information corresponding to field 1 can indicate a wireless charging mode 1, which can be a wireless charging mode with activated beam sweeping, referring to a function of activating scanning of one or more beams transmitted by the first communication device.

[0175] The meanings and functions of fields 2 and 3 can be understood by referring to the introduction of Table 3, wherein field 4 can be used to indicate the number of beams transmitted by the first communication device, such as the bit sequence of P bits in Table 5 indicating the number of beams, for example, if P = 4 and the bit sequence is 0011, it means that the number of beams is 4. Field 5 can be used to indicate the time length of each beam scanning, such as the Y bits in Table 5 indicating the time length of beam scanning. Field 6 can be used to indicate the end time of each beam scanning, such as the Z bits in Table 5 indicating the end time, for example, the end time of beam scanning is indicated by time indication 2, which can be calculated by time indication 2. Field 5 and field 6 can only have one, if field 5 is included, the start time of beam scanning is calculated by time indication 1 of field 2, and the end time of beam scanning can be calculated by the time length of beam scanning of field 5.
