Description

Communication methods and communication devices

[0001] This application claims priority to Chinese Patent Application No. 202411554356.X, filed on October 31, 2024, entitled "Communication Method and Communication Apparatus", the entire contents of which are incorporated herein by reference. Technical Field

[0002] This application relates to the field of wireless communication technology, and more specifically, to a communication method and communication device in a data transmission technology. Background Technology

[0003] To address the issue of short standby lifespan in Internet of Things (IoT) nodes due to their low cost, small size, and inability to carry large-capacity batteries, the industry has proposed using environmental energy harvesting to provide a continuous power source for IoT nodes. Radio frequency (RF) energy is one candidate energy source, offering advantages such as controllable energy volume and source, as well as certain penetration and relatively long transmission distance. Since cellular mobile communication networks have numerous base stations with multiple antennas capable of emitting arbitrarily designed electromagnetic waves and providing directional beams to enhance RF energy in certain directions, frequency bands, and time periods, the inefficiency of energy transmission can be significantly improved. Therefore, wireless energy transmission via base stations is one of the important ways to address the short battery life of IoT devices in the future. However, cellular network resources are limited; if a large amount of resources are used for IoT charging, the resources available for communication will be severely restricted. For IoT nodes, if data can be transmitted simultaneously during charging, resource utilization can be further improved. Therefore, simultaneous wireless information and power transfer (SWIPT) has been proposed as an important technical means.

[0004] In a simultaneous data and energy transmission signal, some frequency domain resource units are used for power generation, and some frequency domain resource units are used for data transmission. The subcarriers used for power generation are called power transmission frequency domain resource units, and the subcarriers used for data transmission are called data frequency domain resource units.

[0005] How to enable the receiving device to correctly identify the location of the energy transmission frequency domain resource unit, so as to demodulate the correct data, is an urgent problem to be solved. Summary of the Invention

[0006] This application provides a communication method that enables the receiving communication device to determine which frequency domain resource units are data frequency domain resource units or power transmission frequency domain resource units, thereby demodulating the correct data.

[0007] Firstly, a communication method is provided, which can be executed by a communication device or a module applied to the communication device (e.g., a processor, chip, or circuit, or a logic module, hardware, and / or software capable of implementing all or part of the functions of the communication device). As an example, the communication device can be a transmitting device capable of transmitting data simultaneously, such as a network device or a terminal device.

[0008] The method may include: generating a first time-domain continuous signal, the first time-domain continuous signal carrying first data, the first time-domain continuous signal being carried on a first orthogonal frequency division multiplexing (OFDM) symbol and N frequency-domain resource units, the N frequency-domain resource units including P first frequency-domain resource units and Q second frequency-domain resource units, the first frequency-domain resource units being used to carry data signals, the second frequency-domain resource units being used to carry energy signals, each of the P first frequency-domain resource units carrying one or more first modulation symbols, each of the Q second frequency-domain resource units carrying one or more second modulation symbols, the constellation point corresponding to the first modulation symbol being a constellation point in a first constellation diagram, the constellation point corresponding to the second modulation symbol being a constellation point in a second constellation diagram, the distance between any constellation point in the second constellation diagram and any constellation point in the first constellation diagram being greater than or equal to a first value; wherein, N, P, and Q are positive integers, P is less than N, and Q is less than N; and transmitting the first time-domain continuous signal.

[0009] Based on the above scheme, a constellation diagram for the power transmission frequency domain resource unit is designed so that the constellation diagrams corresponding to the modulation symbols on the power transmission frequency domain resource unit and the data frequency domain resource unit are different. That is, the data frequency domain resource unit and the power transmission frequency domain resource unit are modulated by different modulation methods, so that the receiving device can correctly identify the position of the power transmission frequency domain resource unit and demodulate the correct data.

[0010] Optionally, the first data refers to the content transmitted during the wireless communication process, which may include one or more of a control channel, a data channel, or a reference signal. In this application, data may be replaced with information.

[0011] Optionally, the frequency domain resource unit in this application may include one or more subcarriers, one or more resource blocks, one or more frequency domain resource blocks, or bandwidth, etc., and this application does not limit it.

[0012] It should be understood that the first constellation diagram corresponds to the first modulation method, which is the modulation method corresponding to the first modulation symbol; the second constellation diagram corresponds to the second modulation method, which is the modulation method corresponding to the second modulation symbol.

[0013] It should be understood that the first modulation symbol is a data symbol and the second modulation symbol is a power transfer symbol.

[0014] It should be understood that the first frequency domain resource unit mentioned above is a data frequency domain resource unit, and the second frequency domain resource unit is a power transmission frequency domain resource unit.

[0015] Optionally, when the frequency domain resource unit is a subcarrier, one modulation symbol is carried on one subcarrier. That is, each of the P first frequency domain resource units carries one first modulation symbol, and each of the Q second frequency domain resource units carries one second modulation symbol. The first frequency domain resource unit can be called the first subcarrier, and the second frequency domain resource unit can be called the second subcarrier.

[0016] In this application, when a frequency domain resource element carries only one modulation symbol, the "frequency domain resource element" can be replaced by a "subcarrier".

[0017] It should be understood that the first subcarrier mentioned above is a data subcarrier, and the second subcarrier is a power transmission subcarrier.

[0018] In some implementations, the first data is the data signal carried by the first frequency domain resource unit.

[0019] In some implementations, the first data includes a first part and a second part, wherein each of the one or more subcarriers included in each of the N frequency domain resource units carries a modulation symbol; generating the first time-domain continuous signal includes: determining the indices of the Q second frequency domain resource units according to the second part; determining P sets of first modulation symbols according to the first part and the first constellation diagram; determining Q sets of second modulation symbols according to the second time-domain continuous signal, the indices of the Q second frequency domain resource units, and the second constellation diagram, wherein the second time-domain continuous signal is carried on the P first frequency domain resource units and the Q second frequency domain resource units, and the P first frequency domain resource units carry the first modulation symbol sets, and the energy on the Q second frequency domain resource units is 0; mapping the P sets of first modulation symbols to the P first frequency domain resource units respectively, and mapping the Q sets of second modulation symbols to the Q second frequency domain resource units respectively. Optionally, a frequency domain resource element includes a subcarrier, a first modulation symbol set includes a first modulation symbol, and a second modulation symbol set includes a second modulation symbol.

[0020] Based on the above scheme, the second modulation symbol can be determined according to the PAPR of the second time-domain continuous signal, and the power transfer frequency domain resource unit can be used for peak clipping, thereby reducing the peak-to-average power ratio (PAPR) of the first time-domain continuous signal, for example, making the PAPR of the first time-domain continuous signal lower than that of the second time-domain continuous signal.

[0021] In this configuration, the P first frequency domain resource units carrying the second time-domain continuous signal carry the first modulation symbol set, and the energy on the Q second frequency domain resource units carrying the second time-domain continuous signal is 0. That is, both the second time-domain continuous signal and the first time-domain continuous signal are carried in the frequency domain on the P first frequency domain resource units and the Q second frequency domain resource units, the difference being that the energy on the Q second frequency domain resource units carrying the second time-domain continuous signal is 0, while the energy on the Q second frequency domain resource units carrying the first time-domain continuous signal is not 0. Alternatively, the first time-domain continuous signal can be obtained by mapping the Q second modulation symbol set determined by the second constellation diagram onto the Q second frequency domain resource units based on the second time-domain continuous signal.

[0022] When determining the Q second modulation symbols, the principle of this application is to minimize the PAPR of the first time-domain continuous signal when, based on the second time-domain continuous signal, for example, by limiting the amplitude of the second time-domain continuous signal or reducing the PAPR of the second time-domain continuous signal, the set of Q second modulation symbols determined by the second constellation diagram is mapped onto the Q second frequency-domain resource units.

[0023] Based on the above scheme, the first data portion is represented using the index of the energy transfer frequency domain resource unit or the index of the data frequency domain resource unit. The data can be carried using the index of the energy transfer frequency domain resource unit or the index of the data frequency domain resource unit, thereby improving spectrum efficiency.

The first PAPR is the PAPR of the time-domain continuous signal obtained by mapping any Q sets of modulation symbols obtained from the second constellation diagram onto the Q second frequency-domain resource units. The Q second frequency-domain resource units have indices of the Q second frequency-domain resource units, and the PAPR of the first time-domain continuous signal is less than the PAPR of the second time-domain continuous signal. Optionally, one frequency-domain resource unit includes one subcarrier, one set of second modulation symbols includes one second modulation symbol, and each of the Q sets of modulation symbols includes one modulation symbol.

[0025] Optionally, the PAPR of the first time-domain continuous signal is equal to the first PAPR, which is the minimum PAPR of the time-domain continuous signal obtained by mapping any Q modulation symbol sets obtained according to the second constellation diagram onto the Q second frequency domain resource units.

[0026] Based on the above scheme, the modulation symbols corresponding to the constellation points included in any Q constellation point set in the second constellation diagram are sequentially mapped onto the subcarriers included in the Q second frequency domain resource units. The modulation symbols included in the Q modulation symbol set corresponding to the constellation points of the Q constellation point set that minimizes the PAPR of the first time domain continuous signal are the second modulation symbols included in the second modulation symbol set.

[0028] Based on the above scheme, Q peak cancellation signals are calculated. When these Q peak cancellation signals are mapped onto Q second frequency domain resource units, the PAPR of the first time domain continuous signal reaches the theoretical minimum value. Then, the modulation symbols included in the set of Q modulation symbols obtained by mapping these Q peak cancellation signals onto the second constellation diagram are the second modulation symbols.

[0169] To facilitate understanding of the embodiments of this application, the following points are provided.

[0170] First, in this application, "for indicating" can include both direct and indirect indication. When describing an indication information as indicating A, it can include whether the indication information directly indicates A or indirectly indicates A, but does not necessarily mean that the indication information includes A.

[0171] The information indicated by the instruction information is called the instruction-to-be-instructed information. In the specific implementation, there are many ways to instruct the instruction-to-be-instructed information. The instruction-to-be-instructed information can be sent as a whole, or it can be divided into multiple sub-information messages and sent separately. Furthermore, the sending period and / or timing of these sub-information messages can be the same or different. This application does not limit the specific sending method. The sending period and / or timing of these sub-information messages can be predefined, for example, according to a protocol, or configured by the transmitting device by sending configuration information to the receiving device.

[0172] Second, in this application, the words "exemplary" or "for example" are used to indicate that something is an example, illustration, or description. Any embodiment or design that is described as "exemplary" or "for example" in this application should not be construed as being more preferred or advantageous than other embodiments or design. Specifically, the use of the words "exemplary" or "for example" is intended to present the relevant concepts in a specific manner.

[0173] Third, in the embodiments of this application, "under the circumstances", "when", and "if" can sometimes be used interchangeably. It should be noted that when the distinction is not emphasized, their intended meanings are consistent.

[0174] Fourth, the term "and / or" in the embodiments of this application is merely a description of the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A existing alone, A and B existing simultaneously, and B existing alone. In addition, the character " / " in this document generally indicates that the related objects before and after it have an "or" relationship.

[0175] Fifth, the various message names or device names involved in the embodiments of this application are merely examples and do not constitute any limitation on the scope of protection of this application. For example, messages may have different names, as long as they can achieve the corresponding functions.

[0176] Sixth, the terms "message", "information", or "information element (IE)" can be used interchangeably in this article. There are no restrictions on the names of messages or information, as long as they can achieve the corresponding functions.

[0177] In this application, "send" and "receive" refer to the direction of signal transmission. For example, "send information to XX" can be understood as the destination of the information being XX, and "send information" can include direct transmission or indirect transmission through other units or modules. "Receive information from YY" can be understood as the source of the information being YY, and "receive information" can include direct reception from YY or indirect reception from YY through other units or modules. Besides air interface transmission or reception signals implemented at the system level, such as network devices or terminal devices, "send" can also be understood as the "output" of a chip interface, and "receive" can also be understood as the "input" of a chip interface. For example, a modem or system-on-a-chip (SoC) chip or system-in-package (SIP) chip transmits or receives signals. "Send" or "receive" can also be performed through device components, for example, by using buses, traces, or interfaces to transmit or receive signals through several parts, modules, or chips of a device.

In the embodiments of this application, the terminal device may be a device that provides voice and / or data connectivity to a user, and can be used to connect people, objects, and machines, such as a handheld device with wireless connectivity, in-vehicle equipment, etc. The terminal device in the embodiments of this application can be a mobile phone, tablet, laptop, PDA, mobile internet device (MID), wearable device, virtual reality (VR) device, augmented reality (AR) device, wireless terminal in industrial control, wireless terminal in self-driving, wireless terminal in remote medical surgery, wireless terminal in smart grid, wireless terminal in transportation safety, wireless terminal in smart city, wireless terminal in smart home, etc. Optionally, the UE can be used as a base station. For example, the UE can act as a scheduling entity, providing sidelink signals between UEs in V2X or SL, etc. The terminal device can also be a terminal device in an IoT system, also known as an IoT node. IoT is an important part of the future development of information technology. Its main technical feature is connecting objects to networks through communication technology, thereby realizing an intelligent network of human-machine interconnection and machine-to-machine interconnection. The connection can be through broadband technology or narrowband technology. IoT technology can achieve massive connectivity, deep coverage, and low power consumption for terminals through technologies such as narrowband (NB). IoT technologies may include reflective communication, spread spectrum, and ultra-wideband (UWB), which will not be elaborated further.

[0182] In this embodiment, the device used to implement the functions of the terminal device can be the terminal device itself; it can also be a device capable of supporting the terminal device in implementing corresponding functions, such as a chip, a chip system, hardware circuits, software modules, or a combination of hardware circuits and software modules. This device can be configured within the terminal device, or it can be located on the terminal side and used in conjunction with the terminal device. The chip system can be composed of chips, or it can include chips and other discrete devices. In this embodiment, only the terminal device is used as an example to illustrate the device used to implement the functions of the terminal device.

[0183] The network device in this application embodiment may include a device that communicates with a terminal device and has wireless transceiver capabilities. The network device can provide wireless communication services, enabling the terminal device to access the wireless network. For example, the network device may refer to a radio access network (RAN) node (or device) used in a cellular network (or mobile network) to connect a terminal device to the wireless network; it may also be a Zigbee base station, a base station in Bluetooth (BT) related technologies, a base station in Bluetooth Low Energy (BLE) technology, a LoRa base station, a Wi-Fi access point, etc. Optionally, a base station can broadly encompass, or replace, various names such as: NodeB, evolved NodeB (eNB), next-generation NodeB (gNB), relay station, access point, transmitting and receiving point (TRP), transmitting point (TP), master station, auxiliary station, motor slide retainer (MSR) node, home base station, network controller, access node, wireless node, access point (AP), transmission node, transceiver node, baseband unit (BBU), remote radio unit (RRU), active antenna unit (AAU), remote radio head (RRH), central unit (CU), distributed unit (DU), radio unit (RU), positioning node, etc. Furthermore, a base station can be a macro base station, micro base station, relay node, donor node, or a combination thereof. A base station can also refer to a communication module, modem, or chip installed within the aforementioned equipment or apparatus. A base station can also be a mobile switching center, a device performing base station functions in D2D, V2X, and M2M communications, a network device (e.g., a base station) in a future communication network, or a device performing network device functions. A base station can support networks using the same or different access technologies. Optionally, a 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). The embodiments of this application do not limit the specific technology or device form used in the network equipment.

[0184] Base stations can be fixed or mobile. For example, a helicopter or drone can be configured to act as a mobile base station, and one or more cells can move depending on the location of the mobile base station. In other examples, a helicopter or drone can be configured as a device to communicate with another base station.

[0185] In some deployments, the network devices mentioned in the embodiments of this application may be devices including CU, DU, or CU and DU, or devices with control plane CU nodes (central unit-control plane (CU-CP)) and user plane CU nodes (central unit-user plane (CU-UP)) and DU nodes. For example, the network devices may include gNB-CU-CP, gNB-CU-UP, and gNB-DU.

[0186] In some deployments, multiple RAN nodes collaborate to assist terminals 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, CU-CPs, CU-UPs, or RUs. CUs and DUs can be configured separately or included in the same network element, such as a BBU. RUs can be included in radio frequency equipment or radio frequency units, such as RRUs, AAUs, or RRHs.

[0187] 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 radio access network (ORAN / O-RAN) system, CU can also be called an open CU (open CU, O-CU), and DU can also be called an open DU (open DU, 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. 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.

[0188] In this embodiment, the device used to implement the functions of the network device can be the network device itself; it can also be a device capable of supporting the network device in implementing the corresponding functions, such as a chip, hardware circuit, software module, or a combination of hardware circuit and software module. This device can be configured within the network device or located on the network side and used in conjunction with the network device. In this embodiment, the network device is used as an example to illustrate the function of the network device, and this does not constitute a limitation on the solutions described in this embodiment.

[0189] The communication method provided in this application can be applied to a variety of communication scenarios.

[0190] Figure 1 illustrates an example of a communication system applicable to the technical solution of this application. In the communication system shown in Figure 1, the communication method provided by this application is applicable to communication between network devices and terminal devices, i.e., uplink or downlink communication. In this communication scenario, the transmitting device in this embodiment can be a terminal device in uplink communication or a network device in downlink communication, and the receiving device can be a network device in uplink communication or a terminal device in downlink communication. Furthermore, it can also be applied to other communication scenarios described above, such as WIFI systems, without limitation.

[0191] Figure 2 is a schematic diagram of an ORAN-based system architecture applicable to embodiments of this application. The O-RAN system may include other components besides those shown in Figure 2. As shown in Figure 2, the access network device (RAN, for example, may be an eNB or gNB or an access network device in a future communication system) communicates with the core network (CN) via a backhaul link and with the UE via an air interface.

[0192] As an example, the baseband unit (BBU) in the access network equipment communicates with the core network via a backhaul link. The radio unit (RU) in the access network equipment communicates with at least one UE via an air interface. The BBU communicates with at least one RU via a fronthaul link; the BBU and RU may or may not be co-located. 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. In some examples, the DU is a logical node carrying one or more of the following functions: radio link control (RLC) layer, medium access control (MAC) layer, higher physical layer (Higher PHY) layer (which may refer to higher-level functions within the physical layer), and others. In some examples, the DU can control at least one RU. The DU connects to the RU via interfaces, which may be fronthaul interfaces. In some examples, an RU is a logical node carrying lower physical layer (PHY) (which can refer to lower-level functions within the PHY layer) and radio frequency (RF) processing. In some examples, an RU can be a transmission reception point (TRP), a remote radio head (RRH), or other similar entity. In some examples, an RU communicates with one or more UEs via a radio link. A DU and RU may or may not be co-located. DUs and RUs can cooperate to implement PHY layer functions. A DU can be connected to one or more RUs. The functions of DUs and RUs can be configured in various ways depending on the design. For example, a DU may be configured to implement baseband functions, and an RU may be configured to implement mid-RF functions. As another example, a DU may be configured to implement higher-level functions within the PHY layer, and an RU may be configured to implement lower-level functions within the PHY layer, or to implement both lower-level and RF functions. Higher-level functions in the physical layer can include a portion of the physical layer's functions that are closer to the MAC layer, while lower-level functions in the physical layer can include another portion of the physical layer's functions that are closer to the mid-RF side.

[0193] The technical solutions of this application embodiment can be applied to wireless communication and / or charging between communication devices. Wireless communication and / or wireless charging between communication devices can include: wireless communication and / or wireless charging between network devices and terminal devices, wireless communication and / or wireless charging between network devices, and wireless communication and / or wireless charging between terminals. Furthermore, in this application embodiment, the term "wireless communication" can also be abbreviated as "communication"; "communication" can also be described as "data transmission," "information transmission," etc. The term "wireless charging" can also be abbreviated as "charging," "energy transfer," or "charging"; "charging" can 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." In addition, the term "wireless data and energy transmission" can also be described as "data and energy transmission," "energy-carrying energy transmission," "data and energy integrated transmission," "energy and data integrated transmission," "communication and energy integrated transmission," "energy and communication integrated transmission," or "wireless data and energy coordinated transmission," etc.

[0194] For ease of understanding, the relevant concepts or technologies involved in this application are introduced.

[0195] 1) Wireless data and energy transmission technology: This is a technology that uses wireless radio frequency signals to carry information and energy simultaneously, allowing information and energy to be received from a single radio frequency signal at the same time.

[0196] In this application, optionally, the wireless signal used for charging can be at least one of the following:

[0197] 1. A signal used to transmit data, that is, to achieve the function of energy transmission at the same time as communication.

[0198] 2. Signals used to transmit control signaling, such as signals carried by the physical downlink shared channel (PDSCH) and / or the physical downlink control channel (PDCCH).

[0199] 3. Reference signals. Examples include sounding reference signals (SRS), channel state information-reference signals (CSI-RS), demodulation reference signals (DMRS), positioning reference signals (PRS), and phase tracking reference signals (PTRS), among other types of reference signals.

[0200] 4. Dedicated non-communication signals, such as signals transmitted within a resource block (RB), a subcarrier, or a frequency band, such as sine wave signals.

[0201] It should be noted that the wireless signals used for charging described above are just examples; other wireless signals can also be used, such as square wave signals, pulse wave signals, or multi-carrier signals.

[0202] For example, as shown in Table 1, the following solutions can be selected for simultaneous data transmission:

[0203] Table 1

[0204] Figure 3 is a schematic diagram of a frequency division multiple energy simultaneous transmission mechanism. Compared with the above scheme, frequency division multiple energy simultaneous transmission transmits WIT and WPT signals in different frequency domain units (such as resource blocks (RB) or resource elements (RE)) without time delay and power interference, which is a preferred scheme.

[0205] As mentioned in the background section, wireless power transfer via frequency division multiplexing is one of the important ways to address the short battery life of IoT nodes in the future. However, the frequency domain position of the power transfer subcarrier may not be fixed. How to enable the receiving device to correctly identify the position of the power transfer subcarrier and thus demodulate the correct data is a problem that urgently needs to be solved.

[0206] The communication method provided in this application will be described in detail below.

[0207] First, the executing entity of the communication method of this application is introduced. The method of this application can be executed by a first device, which can be a communication device or a device used for a communication device (e.g., a chip, processor, circuit, software and / or hardware combined module, etc.). As an example, the first device is a transmitting end device for simultaneous data transmission signals, such as a network device or a terminal device. Optionally, this application may also include a second device. Similarly, the second device can be a communication device or a device used for a communication device (e.g., a chip, processor, circuit, software and / or hardware combined module, etc.). As an example, the second device is a receiving end device for simultaneous data transmission signals, such as a terminal device. Exemplarily, the solution of this application will be described below using network devices and terminal devices as examples.

[0208] The data frequency domain resource unit and the energy transfer frequency domain resource unit in this application will be described in detail below.

[0209] Optionally, the frequency domain resource unit in this application may include one or more subcarriers, one or more resource blocks, one or more frequency domain resource blocks, or bandwidth, etc., and this application does not limit it.

[0210] For ease of understanding and explanation, this application uses "frequency domain resource unit" as an example of "subcarrier" in the following explanation. It should be understood that "subcarrier" in the following text of this application can be replaced with "frequency domain resource unit", or "frequency domain resource unit" can be replaced with "subcarrier" or "resource block" or other specific frequency domain resource unit.

[0211] Optionally, the energy-transmitting subcarrier in this application can carry any modulation symbol to achieve the energy-transmitting effect.

[0212] Alternatively, the power transfer subcarriers in this application may carry peak-shaving symbols (modulation symbols used to limit the peak-to-average power ratio (PAPR) of the transmitted signal, also known as power transfer symbols or energy symbols). Specifically, all subcarriers can be divided into two parts, one part for carrying data symbols and the other part for carrying peak-shaving symbols. The two parts have no overlap. The peak-shaving symbols do not contain information and are only used to change the statistical distribution of the power of the orthogonal frequency division multiplexing (OFDM) time-domain symbols to reduce the PAPR. The subcarriers occupied by the data symbols are called data subcarriers, and the subcarriers occupied by the peak-shaving symbols are called reserved subcarriers, which can also be called power transfer subcarriers or energy subcarriers. It should be understood that the power transfer symbols carried by the power transfer subcarriers may not contain any information and are only used for peak-shaving of the time-domain OFDM symbols.

[0213] Figure 4 is a system framework diagram of the transmitter (transmitting device) and receiver (receiving device) provided in this application. As shown in Figure 4, the transmitter maps data symbols to data subcarriers and energy transmission symbols to energy transmission subcarriers. The receiver is divided into two types: communication receiver and charging receiver. The communication receiver only needs to demodulate and decode the data subcarriers. After performing serial-to-parallel conversion and fast Fourier transform (FFT) on the data and energy transmission symbols, the communication receiver first determines the subcarriers and demodulates the symbols determined to be on the data subcarriers. The charging receiver rectifies, filters, and stores energy for the entire data and energy transmission signal.

[0214] The scheme in this application classifies frequency domain resource units, such as subcarriers, and uses a portion of the reserved frequency domain resource units for peak clipping, that is, reducing the peak power of the signal, thereby reducing the PAPR of the transmitted signal. In this way, both power transmission and reduction of the PAPR of the transmitted signal can be achieved, thereby reducing the requirements for transmitters and receivers.

[0215] To facilitate understanding of the subsequent methods, the method 400 for improving spectral efficiency provided in this application is first introduced.

[0216] It should be understood that this application can carry any symbol on reserved frequency domain resource units, such as reserved subcarriers, to achieve the effect of power transmission. Furthermore, these frequency domain resource units, such as one or more subcarriers, can also transmit specific symbols to reduce the PAPR of the transmitted waveform. However, in this method, the symbols on the power transmission subcarriers do not carry data, which will sacrifice some spectrum resources.

[0217] To overcome this problem, a portion of the first data can be represented using the index of the energy transfer frequency domain resource unit or the index of the data frequency domain resource unit. In addition to the data symbols on the data frequency domain resource unit, the data can also be carried using the index of the energy transfer frequency domain resource unit or the index of the data frequency domain resource unit, thereby improving spectral efficiency.

[0218] For example, taking subcarriers as the unit of frequency domain resources, a portion of the first data (such as the second portion) can be represented using the indices of the data subcarriers (i.e., Q second subcarriers). If N subcarriers are divided into M groups, and K subcarriers are selected from each group to carry data symbols, the index of each data symbol is determined by... Each bit carries its own weight.

[0219] As shown in Figure 5, there are N = 6 subcarriers, divided into M = 3 sub-blocks. Each sub-block has 2 subcarriers, and one data subcarrier is selected from the 2 subcarriers of each sub-block to carry data symbols. For the bit sequence to be transmitted 011000010 (i.e., an example of the first data), using quadrature phase shift keying (QPSK) modulation, it can be decomposed into the bit sequence 01, 1, 00, 0, 01, 0. Mapping 01 and 1 to modulation symbol 1 and index 1 respectively, i.e., placing modulation symbol 1 on the second (index 1: 1) subcarrier of sub-block 1; mapping 00 and 0 to modulation symbol 2 and index 2 respectively, i.e., placing modulation symbol 2 on the first (index 2: 0) subcarrier of sub-block 2; and mapping 01 and 0 to modulation symbol 3 and index 3 respectively, i.e., placing modulation symbol 3 on the first (index 3: 0) subcarrier of sub-block 3, then while still using only 3 subcarriers out of 6 for data transmission, the amount of information it carries increases from 3*2 ​​bits to 3*(2+1) bits, resulting in an improvement in spectral efficiency.

[0220] For example, a portion of the first data (such as the second portion) can be represented using the indices of the power-transmitting subcarriers (i.e., the Q second subcarriers). That is, if the number of power-transmitting subcarriers is M, then the N subcarriers are divided into M groups, and one subcarrier is selected from each group as the power-transmitting subcarrier. The index of the power-transmitting subcarrier is carried by log2N / M bits.

[0221] As shown in Figure 6, there are N = 12 subcarriers, divided into M = 3 sub-blocks. Each sub-block has 4 subcarriers, and one subcarrier is selected from the 4 subcarriers of each sub-block as the power transmission subcarrier. For the bit sequence 010110011100000001011011 (i.e., an example of the first data), using QPSK modulation, it can be decomposed into the bit sequence 010110, 01, 110000, 00, 110000, 11. Mapping 010110 and 01 to modulation symbol group 1 and index 1 respectively, means reserving the second subcarrier in sub-block 1 as a power transmission subcarrier, with modulation symbol group 1 placed sequentially on the remaining subcarriers. Mapping 110000 and 00 to modulation symbol group 2 and index 2 respectively, means reserving the first subcarrier in sub-block 2 as a power transmission subcarrier, with modulation symbol group 2 placed sequentially on the remaining subcarriers. Mapping 010110 and 01 to modulation symbol group 3 and index 3 respectively, means reserving the fourth subcarrier in sub-block 3 as a power transmission subcarrier, with modulation symbol group 3 placed sequentially on the remaining subcarriers. Thus, while only 9 out of 12 subcarriers are used for data transmission, the information carried by each index is equivalent to the data carried by one subcarrier (equivalent when using QPSK and selecting one from 4 subcarriers, i.e., equivalent when modulation order = log2N / M). Therefore, the spectral efficiency under this scheme is consistent with the spectral efficiency when the entire band is occupied by data subcarriers.

[0222] It should be understood that the above representation of a portion of the first data using the index of the energy transfer frequency domain resource unit or the index of the data frequency domain resource unit can be replaced by: encoding a portion of the first data using the index of the energy transfer frequency domain resource unit or the index of the data frequency domain resource unit; or, a portion of the first data having a corresponding relationship with the index of the energy transfer frequency domain resource unit or the index of the data frequency domain resource unit.

[0223] The above scheme can utilize the index of the energy transfer frequency domain resource unit or the index of the data frequency domain resource unit to carry data, thereby improving spectrum efficiency.

[0224] Figure 7 is a schematic flowchart of the communication method 500 provided in this application.

[0225] S510, the network device generates a first time-domain continuous signal, which carries first data. The first time-domain continuous signal is carried on a first orthogonal frequency division multiplexing (OFDM) symbol and N frequency-domain resource units. The N frequency-domain resource units include P first frequency-domain resource units and Q second frequency-domain resource units. The first frequency-domain resource units are used to carry data signals, and the second frequency-domain resource units are used to carry energy signals. Each of the P first frequency-domain resource units carries one or more first modulation symbols (hereinafter referred to as a set of first modulation symbols). Each of the Q second frequency-domain resource units carries one or more second modulation symbols (hereinafter referred to as a set of second modulation symbols).

[0226] Optionally, the frequency domain resource unit in this application may include one or more subcarriers, one or more resource blocks, one or more frequency domain resource blocks, or bandwidth, etc., and this application does not limit it.

[0227] For ease of understanding and explanation, this application uses "frequency domain resource unit" as an example of "subcarrier" in the following explanation. It should be understood that "subcarrier" in the following text of this application can be replaced with "frequency domain resource unit".

[0228] For example, in the case where a frequency domain resource element comprises multiple subcarriers, each frequency domain resource element maps or carries multiple modulation symbols since each subcarrier maps or carries one modulation symbol.

[0229] Then, step S510 above can be replaced as follows: The network device generates a first time-domain continuous signal, the first time-domain continuous signal carries first data, the first time-domain continuous signal is carried on a first orthogonal frequency division multiplexing (OFDM) symbol and N subcarriers, the N subcarriers include P first subcarriers and Q second subcarriers, the first subcarriers are used to carry data signals, the second subcarriers are used to carry energy signals, each of the P first subcarriers carries a first modulation symbol, and each of the Q second subcarriers carries a second modulation symbol.

[0230] Optionally, based on the above-described method 400 for improving spectral efficiency, the first data includes a second part and a third part, wherein the first part is carried on the P first subcarriers and the second part is represented using the indexes of the Q second subcarriers; or, the first part is carried on the P first subcarriers and the second part is represented using the indexes of the P first subcarriers.

[0231] Optionally, the constellation point corresponding to the first modulation symbol is a constellation point in the first constellation diagram, and the constellation point corresponding to the second modulation symbol is a constellation point in the second constellation diagram. The distance between any constellation point in the second constellation diagram and any constellation point in the first constellation diagram is greater than or equal to a first value; wherein, N, P, and Q are positive integers.

[0232] Optionally, the first data refers to the content transmitted during the wireless communication process, which may include one or more of a control channel, a data channel, or a reference signal. In this application, data may be replaced with information.

[0233] It should be understood that the first constellation diagram corresponds to the first modulation method, which is the modulation method corresponding to the first modulation symbol; the second constellation diagram corresponds to the second modulation method, which is the modulation method corresponding to the second modulation symbol.

[0234] It should be understood that the first modulation symbol is a data symbol and the second modulation symbol is a power transfer symbol.

[0235] It should be understood that the first subcarrier mentioned above is a data subcarrier, and the second subcarrier is a power transmission subcarrier.

[0236] With the above scheme, the modulation methods of the symbols on the data subcarriers and the power transmission subcarriers are different. Therefore, the terminal device can determine the data subcarrier index and the power transmission subcarrier index based on the modulation method of the symbols on the subcarriers; or, the terminal device can determine which subcarriers are data subcarriers and which are power transmission subcarriers based on which constellation point the symbol on the subcarrier corresponds to in the constellation diagram; or, the terminal device can determine the data subcarrier index and the power transmission subcarrier index based on the distance between the constellation point corresponding to the symbol on the subcarrier and the constellation point in the first constellation diagram.

[0237] It should be understood that, in order to increase the probability that the terminal device can distinguish the power transmission subcarrier, the distance D between the constellation point corresponding to the modulation symbol on the power transmission subcarrier and the constellation point corresponding to the modulation symbol on the data subcarrier should be relatively large, at least greater than the distance d between the constellation points corresponding to the modulation symbols on the data subcarrier, so as to ensure that the modulation symbol on the power transmission subcarrier can be determined as invalid information.

[0238] For illustrative purposes, Figure 8 illustrates a first constellation diagram and a second constellation diagram. The first constellation diagram includes four constellation points as shown, where the distance between any two constellation points is less than or equal to d (assuming the distance between any two constellation points is d). The second constellation diagram includes multiple constellation points, where the minimum distance D between any constellation point in the second constellation diagram and any constellation point in the first constellation diagram is greater than or equal to a first value. Optionally, the first value is D', which can be a predefined parameter or a parameter configured or indicated by the network device. Optionally, the first value is λd, where λ is a predefined coefficient that characterizes the scaling of the constellation diagram, also known as a scaling parameter. Optionally, λ ≥ 1. Optionally, when the execution subject of this step is a terminal device, λ is a predefined coefficient or a coefficient configured or indicated by the network device.

[0239] It should be understood that when λ is a predefined coefficient, the first value is also predefined; when λ is a coefficient configured or indicated by the network device, the first value is determined based on the configuration or indication of the network device.

[0240] The following describes two methods for generating the first time-domain continuous signal (i.e., two execution methods of step S510), where method one does not use method 400 to improve spectral efficiency, and method two uses method 400 to improve spectral efficiency:

[0241] Method 1

[0242] As shown in Figure 9, step S510 includes the following steps S5101 to S5104, namely, generating the first time-domain continuous signal includes:

[0243] S5101, Based on the first data and the first constellation diagram, determine P sets of first modulation symbols, which may include one or more first modulation symbols.

[0244] In the method shown in Figure 9, the example is taken where the frequency domain resource unit is a subcarrier and the first modulation symbol set includes one first modulation symbol. It is understood that when the frequency domain resource unit includes multiple subcarriers, the first modulation symbol in the following text can be replaced with a first modulation symbol set, where each first modulation symbol set includes multiple first modulation symbols.

[0245] Specifically, the first data is mapped into data symbols through the first constellation diagram, thus obtaining P first modulation symbols.

[0246] It should be understood that the first data is carried on the P first subcarriers, and this step can map the first data into data symbols on the data subcarriers through the first constellation diagram. Here, "mapped into" can be replaced with "modulated into".

[0247] S5102, based on the second time-domain continuous signal, the indexes of the Q second subcarriers and the second constellation diagram, determine Q second modulation symbols, wherein the second time-domain continuous signal is carried on the P first subcarriers and the Q second subcarriers, and the P first subcarriers carry the first modulation symbols, and the energy on the Q second subcarriers is 0.

[0248] Optionally, determining the Q second modulation symbols based on the second time-domain continuous signal, the indices of the Q second subcarriers, and the second constellation diagram includes: determining Q second modulation symbols in the second constellation diagram such that after mapping the Q second modulation symbols onto the Q second subcarriers respectively, the PAPR of the first time-domain continuous signal is less than or equal to a first PAPR, where the first PAPR is the PAPR of the time-domain continuous signal obtained by mapping any Q modulation symbols obtained according to the second constellation diagram onto the Q second subcarriers, and the Q second subcarriers have indices of Q second subcarriers and the PAPR of the first time-domain continuous signal is less than the PAPR of the second time-domain continuous signal. Optionally, the PAPR of the first time-domain continuous signal is the minimum value of the PAPR of the time-domain continuous signal obtained by mapping any Q modulation symbols obtained according to the second constellation diagram onto the Q second subcarriers.

[0249] In this configuration, the P first subcarriers carrying the second time-domain continuous signal carry the first modulation symbol, and the energy on the Q second subcarriers carrying the second time-domain continuous signal is 0. That is, both the second time-domain continuous signal and the first time-domain continuous signal are carried in the frequency domain on the P first subcarriers and the Q second subcarriers, the difference being that the energy on the Q second subcarriers carrying the second time-domain continuous signal is 0, while the energy on the Q second subcarriers carrying the first time-domain continuous signal is not 0.

[0250] Optionally, determining the Q second modulation symbols based on the second time-domain continuous signal, the indices of the Q second subcarriers, and the second constellation diagram includes: determining Q peak cancellation signals on the Q second subcarriers based on the PAPR of the first time-domain continuous signal, and obtaining the Q second modulation symbols based on the Q peak cancellation signals and the second constellation diagram, wherein the Q second subcarriers have indices of the Q second subcarriers and the PAPR of the first time-domain continuous signal is less than the PAPR of the second time-domain continuous signal.

[0251] Specifically, the determined Q peak cancellation symbols enable the PAPR of the second time-domain continuous signal to reach its theoretical minimum value. Furthermore, the Q modulation symbols corresponding to the Q peak cancellation symbols are determined, and the constellation points corresponding to the Q modulation symbols are constellation points on the second constellation diagram.

[0252] Using the above scheme, the energy transmission symbols on the energy transmission subcarriers can be determined through the second constellation diagram.

[0253] S5103, map the P first modulation symbols onto the P first subcarriers respectively, and map the Q second modulation symbols onto the Q second subcarriers respectively.

[0254] In this application, “mapping” can be replaced with “carrying”, and “mapping in” or “mapping to” can be replaced with “carrying in” or “carrying to”.

[0255] S5104 After the full-band subcarrier mapping is completed, the inverse fast fourier transform (IFFT) and serial-to-parallel conversion processes are executed to determine the first continuous signal in the time domain.

[0256] Method 2

[0257] As shown in Figure 10, the first data includes a second part and a third part. Step S510 includes the following steps S5101 to S5105, namely, generating the first time-domain continuous signal includes:

[0258] S5101, determine the index of the Q second subcarriers according to the second part.

[0259] Based on the above-described method 400 for improving spectral efficiency, the second part can be represented using the index of the energy-transmitting subcarriers according to the number of energy-transmitting subcarriers and the second part of the first data, that is, the index of the Q second subcarriers can be determined.

[0260] S5102, Based on the first part and the first constellation diagram, determine P of the first modulation symbols.

[0261] Specifically, the first data is mapped into data symbols through the first constellation diagram, thus obtaining P first modulation symbols.

[0262] It should be understood that the first part of the first data is carried on the P first subcarriers. This step can map the first part of the first data into data symbols on the data subcarriers through the first constellation diagram.

[0263] S5103, based on the second time-domain continuous signal, the indexes of the Q second subcarriers and the second constellation diagram, determine Q second modulation symbols, wherein the second time-domain continuous signal is carried on the P first subcarriers and the Q second subcarriers, and the P first subcarriers carry the first modulation symbols, and the energy on the Q second subcarriers is 0.

[0264] Optionally, determining the Q second modulation symbols based on the second time-domain continuous signal, the indices of the Q second subcarriers, and the second constellation diagram includes: determining Q second modulation symbols in the second constellation diagram such that after mapping the Q second modulation symbols onto the Q second subcarriers respectively, the PAPR of the second time-domain continuous signal is less than or equal to a first PAPR, where the first PAPR is the PAPR of the time-domain continuous signal obtained by mapping any Q modulation symbols obtained according to the second constellation diagram onto the Q second subcarriers, the Q second subcarriers having indices of Q second subcarriers, and the PAPR of the first time-domain continuous signal being less than the PAPR of the second time-domain continuous signal. Optionally, the PAPR of the first time-domain continuous signal is the minimum value of the PAPR of the time-domain continuous signal obtained by mapping any Q modulation symbols obtained according to the second constellation diagram onto the Q second subcarriers.

[0265] In this configuration, the P first subcarriers carrying the second time-domain continuous signal carry the first modulation symbol, and the energy on the Q second subcarriers carrying the second time-domain continuous signal is 0. That is, both the second time-domain continuous signal and the first time-domain continuous signal are carried in the frequency domain on the P first subcarriers and the Q second subcarriers, the difference being that the energy on the Q second subcarriers carrying the second time-domain continuous signal is 0, while the energy on the Q second subcarriers carrying the first time-domain continuous signal is not 0.

[0266] Optionally, determining the Q second modulation symbols based on the second time-domain continuous signal, the indices of the Q second subcarriers, and the second constellation diagram includes: determining Q peak cancellation signals on the Q second subcarriers based on the PAPR of the second time-domain continuous signal, and obtaining the Q second modulation symbols based on the Q peak cancellation signals and the second constellation diagram, wherein the Q second subcarriers have indices of the Q second subcarriers and the PAPR of the first time-domain continuous signal is less than the PAPR of the second time-domain continuous signal.

[0267] Specifically, the determined Q peak cancellation symbols enable the PAPR of the second time-domain continuous signal to reach its theoretical minimum value. Furthermore, the Q modulation symbols corresponding to the Q peak cancellation symbols are determined, and the constellation points corresponding to the Q modulation symbols are constellation points on the second constellation diagram.

[0268] For example, any Q symbols are carried on Q second subcarriers carrying a second time-domain continuous signal, and the PAPR of the obtained time-domain continuous signal is calculated. The PAPR of the obtained time-domain continuous signal has a theoretical minimum value, and the Q symbols that enable the PAPR of the obtained time-domain continuous signal to reach the minimum value are the aforementioned Q peak cancellation symbols. Furthermore, based on the Q peak cancellation symbols, Q corresponding modulation symbols can be determined on the second constellation diagram, and these Q modulation symbols are the aforementioned Q second modulation symbols.

[0269] Using the above scheme, the energy transfer symbols on the energy transfer subcarriers can be determined through the diagram of the second constellation.

[0270] S5104, map the P first modulation symbols onto the P first subcarriers respectively, and map the Q second modulation symbols onto the Q second subcarriers respectively.

[0271] In this application, “mapping” can be replaced with “carrying”, and “mapping in” or “mapping to” can be replaced with “carrying in” or “carrying to”.

[0272] After the full-band subcarrier mapping is completed, S5105 performs IFFT transformation, serial-to-parallel conversion and other processes to determine the first continuous signal in the time domain.

[0273] S520: The network device sends a first time-domain continuous signal to the terminal device; correspondingly, the terminal device receives the first time-domain continuous signal.

[0274] S530, the terminal device determines the first data based on the first time-domain continuous signal.

[0275] S5301, determine N frequency domain resource units corresponding to N modulation symbol sets, for example, determine N modulation symbols corresponding to N subcarriers, wherein each of the N subcarriers corresponds to one modulation symbol. Each modulation symbol set includes one or more modulation symbols, for example, one frequency domain resource unit includes 12 subcarriers, and each modulation symbol set includes 12 modulation symbols.

[0276] It should be understood that each subcarrier carries one modulation symbol. After the terminal device performs serial-to-parallel conversion and FFT on the first time-domain continuous signal, it determines N modulation symbols.

[0277] S5302, determine the indices of P first modulation symbol sets and Q second frequency domain resource units in the N modulation symbol sets according to the mapping of the N modulation symbol sets on the first constellation diagram; or, determine the indices of P first modulation symbol sets and P first frequency domain resource units in the N modulation symbol sets according to the mapping of the N modulation symbol sets on the first constellation diagram. For example, in one possible implementation, a frequency domain resource unit includes a subcarrier, and a (first) modulation symbol set includes a (first) modulation symbol. Determine the indices of P first modulation symbols and Q second subcarriers in the N modulation symbols according to the mapping of the N modulation symbols on the first constellation diagram; or, determine the indices of P first modulation symbols and P first subcarriers in the N modulation symbols according to the mapping of the N modulation symbols on the first constellation diagram.

[0278] In this system, the N modulation symbol sets correspond to N constellation point sets on the first constellation diagram. That is, one modulation symbol set includes X modulation symbols, and one constellation point set includes X constellation points. In one possible implementation, a frequency domain resource unit includes one subcarrier, one modulation symbol set includes one modulation symbol, and the N modulation symbols correspond to N constellation points on the first constellation diagram. It should be understood that signal transmission may be affected by noise; therefore, the constellation point corresponding to a modulation symbol refers to the constellation point in the first constellation diagram that is closest to the mapping point of the modulation symbol on the constellation diagram.

[0279] In the first implementation, in step S5302, the terminal device determines the minimum distance D between the constellation point corresponding to any one of the N modulation symbols and any constellation point in the first constellation diagram, and compares it with λd. When D is greater than or equal to λd, the modulation symbol is a power transmission symbol; when D is less than λd, the modulation symbol is a data symbol. Here, λd represents the product of λ and d.

[0280] For example, as shown in Figure 11, after the terminal device performs serial-to-parallel conversion and FFT operations, the modulation symbols on each subcarrier are as shown in Figure 11. It can be seen that the modulation symbol (10+10j) on the 5th subcarrier is the closest constellation point on the first constellation diagram corresponding to the QPSK modulation used. If the distance exceeds λd (taking λ=3, d=2 as an example), where d is the distance between constellation points corresponding to the modulation symbol on the data subcarrier, then it can be determined that the modulation symbol is a power transmission symbol and the subcarrier corresponding to the modulation symbol is a power transmission subcarrier.

[0281] It should be noted that the bit sequence obtained after demapping the power subcarrier and the bit sequence obtained after demodulating the data subcarrier can be combined according to certain rules to obtain a complete bit sequence. These rules can be pre-configured or indicated by the network device to the terminal device.

[0282] Optionally, the aforementioned D' or λ can be pre-configured or indicated by the network device to the terminal device. For example, the network device sends first information to the terminal device, the first information indicating the positional relationship between the first constellation diagram and the second constellation diagram, such as indicating the aforementioned D' or λ.

[0283] In the second implementation, step S5302, determining the first data based on the first time-domain continuous signal further includes: determining P first modulation symbols and Q second modulation symbols among the N modulation symbols based on the mapping of the N modulation symbols on the first constellation diagram and the second constellation diagram.

[0284] Specifically, the terminal device determines N constellation points in the first constellation diagram and the second constellation diagram that correspond to the N modulation symbols respectively, wherein P constellation points among the N constellation points belong to the first constellation diagram and Q constellation points among the N constellation points belong to the second constellation diagram; determines P modulation symbols corresponding to the P constellation points as the first modulation symbols, and determines Q modulation symbols corresponding to the Q constellation points as the second modulation symbols.

[0285] For example, as shown in Figure 11, after the terminal device performs serial-to-parallel conversion and FFT operation, the modulation symbols on each subcarrier are shown in Figure 11. It can be seen that the constellation point corresponding to the modulation symbol (10+10j) on the 5th subcarrier is the constellation point on the second constellation diagram. Therefore, it can be determined that the modulation symbol is a power transmission symbol, and the subcarrier corresponding to the modulation symbol is a power transmission subcarrier.

[0286] Optionally, the second constellation diagram is determined by the terminal device based on the first constellation diagram. The terminal device determines the second constellation diagram based on the aforementioned D' or λ and the first constellation diagram. For example, different values ​​of the first value, such as D', or λ, are associated with different constellation diagrams. The terminal device determines that the modulation symbols on the data subcarriers correspond to the first constellation diagram, and after obtaining the value of λ, it can determine that the modulation symbols on the energy subcarriers correspond to the second constellation diagram. Here, D' or λ can be pre-configured or indicated to the terminal device by the network device. For example, the network device sends first information to the terminal device, indicating the positional relationship between the first and second constellation diagrams, such as indicating D' or λ.

[0287] S5303, determine the first data based on the P sets of first modulation symbols. For example, if a set of first modulation symbols includes one first modulation symbol, then determine the first data based on the P sets of first modulation symbols.

[0288] Optionally, if information is carried through the index of the power transmission frequency domain resource unit, then determining the first data based on the P first modulation symbol sets includes: determining the first data based on the P first modulation symbol sets and the indexes of the Q second frequency domain resource units.

[0289] Optionally, if information is carried through the index of the data frequency domain resource unit, then determining the first data based on the P first modulation symbol sets includes: determining the first data based on the P first modulation symbol sets and the indexes of the P first frequency domain resource units.

[0290] Optionally, if information is not carried through the index of the frequency domain resource unit, the first data is determined solely based on the P sets of first modulation symbols.

[0291] For example, the above (first / second) frequency domain resource unit includes a subcarrier, and the first modulation symbol set includes a first modulation symbol.

[0292] For example, when information is carried through the index of a subcarrier, as shown in Figure 11, assuming that the index of the power transmission subcarrier is part of the valid information, after demapping the power transmission subcarrier, we get 101, which can be placed after the demodulated bits according to certain rules, for example, after the demodulated bit sequence, to obtain the complete data bits 0011010010101.

[0293] Compared to this example, if data is not carried through the subcarrier index, i.e. the energy-transmitting subcarrier index is not valid information, then the final determined bit sequence is 0011010010.

[0294] In the example above, QPSK modulation is used on 6 subcarriers. A full subcarrier as a data subcarrier can carry 12 bits. If one subcarrier is reserved as a subcarrier, the index of that subcarrier can carry 3 bits of data. Therefore, under the reserved subcarrier scheme, 13 bits can be carried (5*2+3=13). From the perspective of spectral efficiency, there is not only no loss but also a certain improvement.

[0295] Based on the above scheme, the data subcarriers included in the data frequency domain resource unit and the energy transmission subcarriers included in the energy transmission frequency domain resource unit are modulated by different modulation methods, or in other words, constellation diagrams for the energy transmission subcarriers are designed so that the constellation diagrams corresponding to the energy transmission subcarriers and the data subcarriers are different, so that the receiving device can correctly identify the position of the energy transmission subcarriers and thus demodulate the correct data.

[0296] In method 500, the receiving device correctly identifies the position of the power subcarrier by using different modulation schemes for the data subcarrier and the power subcarrier. This application also provides another method 600, where the terminal device can directly determine the index of the data subcarrier included in the data frequency domain resource unit and the index of the power subcarrier included in the power frequency domain resource unit based on the energy difference between the data subcarrier and the power subcarrier in the first time-domain continuous signal. This method does not require special design of the modulation schemes for the data subcarrier and the power subcarrier, i.e., it does not require special design of the signal constellation diagram.

[0297] The method includes:

[0298] S610, the network device generates a first time-domain continuous signal. This first time-domain continuous signal carries first data and is carried on a first orthogonal frequency division multiplexing (OFDM) symbol and N frequency-domain resource units. The N frequency-domain resource units include P first frequency-domain resource units and Q second frequency-domain resource units. The first frequency-domain resource units carry data signals, and the second frequency-domain resource units carry energy signals. Each first subcarrier within each of the P first frequency-domain resource units carries a first modulation symbol, and each second subcarrier within each of the Q second frequency-domain resource units carries a second modulation symbol. A frequency-domain resource unit includes one or more subcarriers, and correspondingly, one frequency-domain resource unit carries one or more (first / second) modulation symbols.

[0299] Optionally, based on the above-described method 400 for improving spectral efficiency, the first data includes a second part and a third part, wherein the first part is carried on the P first frequency domain resource units, and the second part is represented using the indexes of the Q second frequency domain resource units; or, the first part is carried on the P first frequency domain resource units, and the second part is represented using the indexes of the P first frequency domain resource units.

[0300] S620, the network device sends a first time-domain continuous signal to the terminal device; correspondingly, the terminal device receives the first time-domain continuous signal.

[0301] S630, the terminal device determines the first data based on the first time-domain continuous signal.

[0302] Optionally, the average energy of the frequency domain resource units in the first time-domain continuous signal is k'. The terminal device determines frequency domain resource units with energy greater than or equal to α'k' as energy transmission frequency domain resource units, and / or determines frequency domain resource units with energy less than or equal to β'k' as data frequency domain resource units. Wherein, α'≥1, β'≤1.

[0303] Optionally, the average energy of the subcarriers in the first time-domain continuous signal is k. The terminal device determines subcarriers with energy greater than or equal to αk as energy-transmitting subcarriers, and / or determines subcarriers with energy less than or equal to βk as data subcarriers. Where α≥1, β≤1.

[0304] Optionally, the aforementioned α or α' can be pre-configured or indicated by the network device to the terminal device. For example, the network device sends second information to the terminal device, the second information indicating α or α'.

[0305] Optionally, the aforementioned β or β' can be pre-configured or indicated by the network device to the terminal device. For example, the network device sends third information to the terminal device, the third information indicating β or β'.

[0306] The following describes a method for determining power transmission frequency domain resource units / data frequency domain resource units in a simultaneous power and data transmission signal, namely communication method 700. This method determines which frequency domain resource units are used as data frequency domain resource units and which are used as power transmission frequency domain resource units based on channel measurement results. It should be noted that method 700 can be implemented independently or combined with method 500, i.e., method 700 can be used in method 500 as a scheme to determine P first frequency domain resource units and Q second frequency domain resource units. A frequency domain resource unit may include one or more subcarriers. For example, in the description corresponding to Figure 12, a frequency domain resource unit can be replaced with a subcarrier or a resource block. For instance, since a resource block includes multiple subcarriers, the description may replace some frequency domain resource units with subcarriers, some with resource blocks, or all with subcarriers or all with resource blocks.

[0307] Figure 12 is a schematic flowchart of the communication method 700 provided in this application.

[0308] In S710, the network device sends a reference signal to the terminal device; correspondingly, the terminal device receives the reference signal.

[0309] Optionally, the reference signal is a downlink reference signal. It should be understood that the method of this application is illustrated using the example of the first device being a network device and the second device being a terminal device. When the transmitting or receiving device is another device, the reference signal can also be an uplink reference signal or other reference signals.

[0310] S720, the terminal device determines a first measurement report based on a reference signal. The first measurement report indicates U frequency domain resource units, wherein the U frequency domain resource units are used to determine the Q second frequency domain resource units, the second frequency domain resource units are used to carry energy signals, and U and Q are positive integers.

[0311] It is understandable that U frequency domain resource units can be U subcarriers and Q second frequency domain resource units can be Q second subcarriers, or U frequency domain resource units can be U subcarriers and Q second frequency domain resource units can be Q second resource blocks, or U frequency domain resource units can be U resource blocks and Q second frequency domain resource units can be Q second subcarriers.

[0312] It should be understood that the first measurement report is determined based on the channel measurement results of the reference signal, indicating which frequency domain resource units are suitable as power transfer frequency domain resource units.

[0313] It should be understood that the aforementioned U frequency domain resource units are frequency domain resource units that are determined by the terminal equipment to be suitable as power transmission frequency domain resource units.

[0314] Optionally, the first measurement report includes indexes of the U frequency domain resource units, which are used to determine the Q second frequency domain resource units.

[0315] For example, the index of the power transfer frequency domain resource unit can be fed back according to certain principles. For example, from the perspective of communication, the frequency domain resource unit with a relatively low carrier to interference plus noise ratio (CINR) can be fed back. Or, from the perspective of power supply, the frequency domain resource unit with higher channel quality is more suitable as the power transfer frequency domain resource unit, so the frequency domain resource unit with higher channel quality can be fed back.

[0316] Optionally, the first measurement report includes indices of O frequency domain resource units, which are used to determine the P first frequency domain resource units. The first frequency domain resource units are used to carry data signals, and O is a positive integer.

[0317] For example, the index of the frequency domain resource unit can be fed back according to certain principles. For example, from the perspective of communication, the frequency domain resource unit with a relatively high CINR can be fed back. Or, from the perspective of power supply, the frequency domain resource unit with higher channel quality is more suitable as the power transmission frequency domain resource unit, and the frequency domain resource unit with lower channel quality can be fed back.

[0318] It should be understood that the aforementioned O frequency domain resource units are frequency domain resource units that the terminal device has determined are suitable as data frequency domain resource units.

[0319] Optionally, the first measurement report includes the signal-to-noise ratio of different frequency domain resource elements in the reference signal.

[0320] S730: The terminal device sends a first measurement report to the network device; correspondingly, the network device receives the first measurement report.

[0321] S740, the network device determines P first frequency domain resource units and Q second frequency domain resource units based on the first measurement report.

[0322] It should be understood that the location of the power transmission frequency domain resource unit is ultimately determined by the network equipment. The network equipment can further determine the power transmission frequency domain resource unit based on the first measurement report and other factors, or it can decide entirely based on the first measurement report fed back by the terminal.

[0323] Optionally, before step S710, method 700 further includes:

[0324] S750, the network device sends first configuration information to the terminal device, the first configuration information being used to determine the aforementioned first measurement report; correspondingly, the terminal device receives the first configuration information.

[0325] When step S750 is executed, the terminal device in step S720 determines the first measurement report based on the reference signal, which includes: the terminal device determines the first measurement report based on the reference signal and the first configuration information.

[0326] Optionally, the first configuration information indicates one or more of the following:

[0327] The first quantity indicates the number of frequency domain resource units that need to be reported and can be used to carry energy signals;

[0328] The first proportion indicates the ratio of the number of frequency domain resource units that need to be reported and can be used to carry energy signals to the total number of frequency domain resource units in the reference signal.

[0329] The first communication capacity threshold indicates that the ratio of the communication capacity of the frequency domain resource units that need to be reported and can be used to carry data signals to the total communication capacity is greater than the first communication capacity threshold. The total communication capacity is the communication capacity when all frequency domain resource units in the reference signal are used for communication.

[0330] The first energy threshold indicates that the ratio of the energy of the frequency domain resource units that need to be reported and can be used to carry the energy signal to the total energy is greater than the first energy threshold. The total energy is the communication capacity when all frequency domain resource units in the reference signal are used for charging.

[0331] A modulation and coding scheme (MCS) refers to the modulation and coding scheme used on frequency domain resource units to carry data signals.

[0332] For example, when the first configuration information indicates a first quantity, the number U of frequency domain resource units indicated by the first measurement report is less than or equal to the first quantity.

[0333] For example, when the first configuration information indicates the first proportion, the proportion of the U frequency domain resource units indicated by the first measurement report to the N frequency domain resource units corresponding to the reference signal is less than or equal to the first proportion.

[0334] For example, when the first configuration information indicates the first communication capacity threshold, the communication capacity of the N frequency domain resource units corresponding to the reference signal, except for the U frequency domain resource units indicated by the first measurement report, is less than or equal to the first communication capacity threshold.

[0335] For example, when the first configuration information indicates a first energy threshold, the energy transmitted by the U frequency domain resource units indicated by the first measurement report is less than or equal to the first energy threshold.

[0336] For example, when the first configuration information indicates the MCS, the smaller the MCS order, the smaller the number of power transmission frequency domain resource units required to ensure the data rate.

[0337] The following describes another method for determining the power transmission frequency domain resource units / data frequency domain resource units in a simultaneous power transmission signal, namely communication method 800. This method determines which frequency domain resource units are used as data frequency domain resource units and which are used as power transmission frequency domain resource units based on channel measurement results. It should be noted that method 800 can be implemented independently or in combination with method 800, i.e., method 800 can be used in method 500 as a scheme to determine P first frequency domain resource units and Q second frequency domain resource units. A frequency domain resource unit may include one or more subcarriers. For example, in the description corresponding to Figure 13, the frequency domain resource unit can be replaced with a subcarrier or a resource block. For instance, since a resource block includes multiple subcarriers, the description may replace some frequency domain resource units with subcarriers, some with resource blocks, or all with subcarriers, or all with resource blocks.

[0338] Figure 13 is a schematic flowchart of the communication method 800 provided in this application.

[0339] In S810, the terminal device sends a reference signal to the network device; correspondingly, the network device receives the reference signal.

[0340] Optionally, the reference signal is an uplink reference signal. It should be understood that the method of this application is described using the first device as a network device and the second device as a terminal device as an example. When the transmitting device or the receiving device is another device, the reference signal can also be an uplink reference signal or other reference signals.

[0341] In S820, network devices determine P first frequency domain resource elements and Q second frequency domain resource elements based on reference signals.

[0342] For example, the frequency domain resource unit for power transmission can be determined according to certain principles. For instance, from a communication perspective, the frequency domain resource unit with a relatively low relative carrier interference and noise ratio (CINR) can be fed back. Or, from a power supply perspective, the frequency domain resource unit with higher channel quality is more suitable as the power transmission frequency domain resource unit, so the frequency domain resource unit with higher channel quality can be fed back.

[0343] For example, data frequency domain resource units can be determined according to certain principles. For instance, from a communication perspective, frequency domain resource units with relatively high CINR can be used for feedback. Or, from a power supply perspective, frequency domain resource units with higher channel quality are more suitable for power transmission frequency domain resource units, while frequency domain resource units with lower channel quality can be used for feedback.

[0344] After determining P first frequency domain resource units and Q second frequency domain resource units through method 700 or method 800, the network device can display the finally determined power transmission frequency domain resource units and / or data frequency domain resource units to the terminal device, or it can directly send a data transmission signal according to the first measurement report sent by the terminal device, or it can execute method 500.
