[0027] The technical solution in this application will be described below with reference to the accompanying drawings.

[0028] Wireless communication systems

[0029] Figure 1 is a diagram illustrating an example of the system architecture of a wireless communication system 100 to which an embodiment of the present application may be applied. The wireless communication system 100 may include a network device 110 and a terminal device 120. The network device 110 may be a device that communicates with the terminal device 120. The network device 110 may provide network coverage for a specific geographical area and may communicate with the terminal device 120 located within the coverage area. The terminal device 120 may access a network (e.g., a wireless network) through the network device 110. Optionally, the wireless communication system 100 may also include other network entities such as a network controller and a mobility management entity, which is not limited in the embodiments of the present application.

[0030] It should be understood that the technical solutions of the embodiments of the present application can be applied to various communication systems, such as: the fifth generation (5G) system or NR, long term evolution (LTE) system, LTE frequency division duplex (FDD) system, LTE time division duplex (TDD), etc. The technical solutions provided in this application can also be applied to future communication systems, such as the sixth generation mobile communication system, satellite communication system, etc.

The terminal device in the embodiments of the present application may refer to 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 connection function, a vehicle-mounted device, etc. The terminal device in the embodiments of the present application can be a mobile phone, a tablet computer, a laptop computer, a PDA, a mobile internet device (MID), a wearable device, a virtual reality (VR) device, an augmented reality (AR) device, a wireless terminal in industrial control, a wireless terminal in self-driving, a wireless terminal in remote medical surgery, a wireless terminal in a smart grid, a wireless terminal in transportation safety, a wireless terminal in a smart city, a wireless terminal in a smart home, etc. Optionally, the terminal device can be used to act as a base station. For example, the terminal device can act as a scheduling entity that provides sidelink signals between terminal devices in V2X or D2D. For example, a cellular phone and a car communicate with each other using sidelink signals. The cellular phone and smart home devices communicate without relaying the communication signal through a base station.

[0032] The network device in the embodiment of the present application may be a device for communicating with a terminal device. The network device may be, for example, an access network device or a wireless access network device. For example, the network device may be a base station.

[0033] Terminal devices can communicate with each other via sidelinks. Sidelink communication can also be called proximity services (ProSe) communication, unilateral communication, sidelink communication, or device-to-device (D2D) communication.

[0034] Zero-power communication

[0035] Zero-power communication is a type of wireless communication technology. Zero-power communication can realize communication between network devices and terminal devices based on radio frequency power harvesting and backscatter communication technology. Referring to Figure 2, the zero-power communication network may include a network device 110 and a terminal device 120. In the zero-power communication network, the terminal device 120 may be referred to as a zero-power terminal. The network device 110 may be used to send a wireless power supply signal / downlink communication signal 130 to the zero-power terminal 120, and may receive a backscatter signal 140 from the zero-power terminal 120. The zero-power terminal 120 may include an energy harvesting module 121 and a backscatter communication module 122. In addition, the zero-power terminal 120 may also include a low-power computing module 123 and / or one or more memories or sensor modules 124. The one or more memories or sensor modules 124 may be used to store some basic information (such as item identification, etc.) or obtain sensor data such as ambient temperature and ambient humidity.

[0036] FIG3 shows a possible structure of the energy collection module 121. As shown in FIG3, the energy collection module 121 can collect the energy of the spatial electromagnetic waves of the radio frequency signal based on the principle of electromagnetic induction, and store the collected energy in the capacitor C. The above process can be understood as the charging process of the capacitor C. When the charging process of the capacitor C is completed, the capacitor C can start to discharge to provide energy for the zero-power terminal 120. For example, the discharge of the capacitor C can be used to drive the zero-power terminal 120 to perform low-power demodulation on the data sent by the network device 110. For another example, the discharge of the capacitor C can be used to drive the zero-power terminal 120 to modulate the data to be sent. For another example, the discharge of the capacitor C can be used to drive the sensor of the zero-power terminal 120 to collect data. For another example, the discharge of the capacitor C can be used to drive the zero-power terminal 120 to read data in the memory, etc.

[0037] The backscatter communication module 122 can be used for backscatter communication between the zero-power terminal 120 and the network device 110. The principle of backscatter communication is described below in conjunction with FIG4 . Referring to FIG4 , the zero-power terminal 120 receives a wireless signal 130 transmitted by the network device 110 and modulates the wireless signal 130 to carry the data to be transmitted. Finally, the zero-power terminal 120 radiates the modulated signal 140 from the antenna. This information transmission process is called backscatter communication. The wireless signal 130 can also be referred to as a carrier signal. A carrier signal can refer to an unmodulated wireless signal. For example, a carrier signal can be a sinusoidal wave signal. Backscatter communication and load modulation are closely related. The load modulation function can be understood as adjusting and controlling the circuit parameters of the oscillation circuit of the zero-power terminal 120 according to the rhythm of the data stream, thereby changing parameters such as the impedance of the zero-power terminal 120, thereby completing the modulation process.

[0038] In some implementations, the transmit (transmit, TX) path of the network device 110 may be further provided with other devices for processing the transmitted signal, such as an amplifier (AMP). The receive (receive, RX) path of the network device 110 may also be provided with other devices for processing the received signal, such as a low noise amplifier (LNA).

[0039] Typically, load modulation can be achieved through resistive load modulation and capacitive load modulation. Figure 5 shows a circuit diagram of a zero-power terminal based on resistive load modulation technology. It should be noted that the circuit shown in Figure 5 implements load modulation technology in a manner similar to that of existing circuits implementing load modulation technology. For the sake of simplicity, the functions of resistors R2 and R3, capacitors C1 and C2, and inductors L1 and L2 shown in Figure 5 are not further described.

[0040] In resistive load modulation, a resistor RL is connected in parallel with the load. A switch S can be controlled by a binary data stream to turn the resistor RL on or off. This switching of the resistor RL causes a change in the circuit voltage, which in turn controls the amplitude of the backscattered signal from the zero-power terminal, thereby modulating the backscattered signal using amplitude-shift keying (ASK).

[0041] Similarly, in capacitive load modulation, the on / off switching of the capacitor can be controlled based on a binary data stream to change the circuit resonant frequency, thereby changing the operating frequency of the backscattered signal to implement frequency-shift keying (FSK) modulation.

[0042] As mentioned above, a zero-power terminal can use load modulation to modulate the incoming signal (i.e., the carrier signal) to achieve backscatter communication. Therefore, zero-power terminals in backscatter communication generally have the following advantages.

[0043] Advantage 1: Since zero-power terminals do not need to actively transmit signals, they do not require complex RF pathways. For example, components such as power amplifiers (PAs) and RF filters can be omitted from the RF pathway, reducing the cost and size of the terminal device.

[0044] The second advantage is that since zero-power terminals do not need to actively generate high-frequency signals, they do not require high-frequency crystal oscillators, thereby reducing the cost and size of terminal equipment.

[0045] Advantage three: Since zero-power terminals can use backscatter technology to communicate with network devices, they consume less energy during communication and do not even need to consume their own energy.

[0046] In addition to the backscatter communication, energy harvesting, and load modulation functions described above, zero-power terminals can also have encoding functions. The data transmitted by the encoding end (such as a zero-power terminal or electronic tag) can use different forms of codes to represent binary "1" and "0". In zero-power communication systems, commonly used encoding methods may include: reverse non-return-to-zero (NRZ) encoding, Manchester encoding, unipolar return-to-zero (Unipolar RZ) encoding, differential bi-phase (DBP) encoding, Miller encoding, and differential encoding. In layman's terms, the encoding process is to use different pulse signals to represent 0 and 1.

[0047] Classification of zero-power terminals

[0048] Zero-power terminals can be divided into three categories based on energy storage capacity and whether they have the ability to generate RF signals for signal transmission. The first category can be called device A (Device A), the second category can be called device B (Device B), and the third category can be called device C (Device C).

[0049] Device A does not have energy storage capabilities, independent signal generation and amplification capabilities, and can only rely on backscatter communication to send signals.

[0050] Device B has energy storage capabilities, but cannot independently generate signals and can only transmit signals using backscattering. The energy stored in Device B can be used to amplify the reflected scattered signal.

[0051] Device C has an energy storage function. In addition, Device C can independently generate signals, that is, Device C can actively send signals.

[0052] Coverage Level

[0053] In order to support coverage enhancement, some communication systems (such as narrowband internet of things (NB-IoT) and enhanced machine-type communication (eMTC) systems) have introduced the concept of coverage enhancement level (CE Level). For example, for NB-IoT, three levels are defined: CE Level 0, 1, and 2, which can respectively resist signal attenuation of 144dB, 154dB, and 164dB. Among the above three levels, CE Level 0 can be called normal coverage, and the remaining CE Levels can be called enhanced coverage. Network equipment can select the corresponding number of signal retransmissions based on the CE Level of the NB-IoT terminal. For eMTC, four levels are defined: CE Level 0, 1, 2, and 3, which respectively resist different degrees of signal attenuation. The concept of coverage level of eMTC is basically similar to that of NB-IoT and will not be described in detail here.

[0054] Determination of coverage level during random access

[0055] The terminal device (for example, it can be an NB-IoT terminal or an eMTC terminal) can determine its corresponding initial coverage level during the random access initialization phase. For example, if this random access process is triggered by a physical downlink control channel order (PDCCH order), and the PDCCH order indicates the initial coverage level, or for the NB-IoT terminal, the PDCCH order indicates the initial narrowband physical random access channel (NPRACH) repetition number; or the upper layer configures the initial coverage level, the terminal device can consider itself to be at the initial coverage level indicated by the network device. Otherwise, the terminal device can determine its own initial coverage level based on the reference signal receiving power (RSRP) measurement. The way in which the terminal device determines the initial coverage level based on the RSSP measurement can be performed as described below.

[0056] If the higher layer configures the RSRP threshold corresponding to CE Level 3, and the RSRP measured by the terminal device is lower than the RSRP threshold corresponding to CE Level 3, and the terminal device supports CE Level 3, the terminal device considers itself to be in CE Level 3;

[0057] Otherwise, if the higher layer configures the RSRP threshold corresponding to CE Level 2, and the RSRP measured by the terminal device is lower than the RSRP threshold corresponding to CE Level 2, and the terminal device supports CE Level 2, the terminal device considers itself to be in CE Level 2;

[0058] Otherwise, if the higher layer configures the RSRP threshold corresponding to CE Level 1, and the RSRP measured by the terminal device is lower than the RSRP threshold corresponding to CE Level 1, and the terminal device supports CE Level 1, the terminal device considers itself to be in CE Level 1;

[0059] Otherwise, the terminal device can consider itself to be in CE Level 0.

[0060] In wireless communication systems, terminal devices often need to determine transmission resources before communicating with network devices. Different terminal devices have different situations, and how to determine appropriate transmission resources for terminal devices has always been a hot topic in the field of wireless communications. Taking zero-power terminals as an example, zero-power terminals usually obtain energy by collecting radio waves sent by network devices, or obtain energy from the surrounding environment (such as solar energy). After obtaining energy, the zero-power terminal can drive itself to work. Different zero-power terminals may have different energy collection efficiency and / or coverage conditions, so the coverage supported by the energy collected by the zero-power terminal may also vary. In view of these differences, how to determine appropriate transmission resources for terminal devices is a problem that needs to be solved.

[0061] In response to the above problems, an embodiment of the present application proposes a method for wireless communication (or resource selection method), which can take into account the differences between terminal devices when selecting transmission resources, thereby selecting more suitable transmission resources for the terminal devices.

[0062] The embodiment of the present application is described in more detail below with reference to FIG6 .

[0063] 6 , the method for wireless communication provided in an embodiment of the present application may include step S610 , that is, the terminal device determines a first transmission resource from one or more transmission resources based on the first information.

[0064] In some embodiments, the one or more transmission resources may include one or more of the following: uplink transmission resources and downlink transmission resources. Taking uplink transmission resources as an example, the one or more transmission resources may include one or more of the following: uplink access resources and uplink data transmission resources. The uplink access resources may be, for example, PRACH resources. The uplink data transmission resources may be, for example, physical uplink shared channel (PUSCH) resources.

[0065] In some embodiments, different transmission resources among the multiple transmission resources mentioned in step S610 may include different characteristics. The characteristics mentioned here may refer to a modulation and coding scheme (MCS) and / or a repetition number. It should be understood that the repetition number mentioned in the embodiment of the present application may refer to the number of repeated transmissions of a signal / channel. Taking the transmission resource as a PRACH resource as an example, the repetition number mentioned in the embodiment of the present application may refer to the number of repeated transmissions of the PRACH. Taking the transmission resource as a PUSCH resource as an example, the repetition number mentioned in the embodiment of the present application may refer to the number of repeated transmissions of the PUSCH.

[0066] In some embodiments, the multiple transmission resources mentioned in step S610 may correspond to multiple MCSs. In other words, the multiple transmission resources may be multiple transmission resources with different MCSs.

[0067] In some embodiments, the multiple transmission resources mentioned in step S610 may be represented based on multiple MCSs.

[0068] In some embodiments, the multiple transmission resources mentioned in step S610 may correspond to multiple repetition times. In other words, the multiple transmission resources may be multiple transmission resources with different repetition times.

[0069] In some embodiments, the multiple transmission resources mentioned in step S610 can be represented based on multiple repetition times.

[0070] In some embodiments, step S610 may be replaced by: the terminal device may determine a characteristic from multiple characteristics of the transmission resource based on the first information. For example, the terminal device may select an MCS from multiple MCSs based on the first information. For another example, the terminal device may select a repetition count from multiple repetition counts based on the first information.

[0071] In some embodiments, the first information may include (or be used to indicate, or be used to determine) energy storage-related information of the terminal device. Different energy storage-related information of the terminal devices may result in different coverage ranges supported by the terminal devices. Therefore, considering the differences in energy storage-related information between different terminal devices when selecting transmission resources (or selecting the characteristics of transmission resources) helps to improve the transmission success rate of the terminal devices.

[0072] In some embodiments, the first information may include (or be used to indicate, or be used to determine) energy storage related information of the terminal device and coverage information of the terminal device. If the energy storage related information of the terminal device is different, the coverage range supported by the terminal device may be different. Therefore, considering the differences between energy storage related information of different terminal devices when selecting transmission resources (or selecting the characteristics of transmission resources) helps to improve the transmission success rate of the terminal device. Furthermore, considering the coverage of the terminal device while considering the energy storage related information helps the terminal device to select a more suitable transmission resource. For example, if the coverage of the terminal device is good, even if the terminal device currently stores a lot of energy, a transmission resource with a lower number of repetitions can be selected, thereby avoiding resource waste on the one hand and avoiding excessive power consumption caused by too many retransmissions on the other.

[0073] In some embodiments, the energy storage related information of the terminal device may include (or be used to indicate, or be used to determine) one or more of the following information: energy storage information of the terminal device; and power information of the terminal device.

[0074] In some embodiments, the energy storage information of a terminal device may include (or be used to indicate, or be used to determine) one or more of the following information: the energy storage capacity of the terminal device; and the energy currently stored in the terminal device. The energy storage capacity of the terminal device may, for example, indicate the maximum amount of stored energy that the terminal device can support. The energy currently stored in the terminal device may, for example, refer to the energy stored in the terminal device via wireless RF power supply and / or other power supply methods (e.g., environmental power supply such as solar energy and / or wind energy).

[0075] In some embodiments, the power information of the terminal device may include (or be used to indicate, or be used to determine) the transmit power of the terminal device or the backscatter power of the terminal device. For example, the power information of the terminal device may include (or be used to indicate, or be used to determine) one or more of the following information: the maximum transmit power supported by the terminal device; the transmit power currently available to the terminal device; the maximum backscatter power supported by the terminal device; and the backscatter power currently available to the terminal device.

[0076] In some embodiments, the coverage information of a terminal device may be used to indicate a coverage condition or coverage status of the terminal device, such as indicating the signal quality of the terminal device in a serving cell. The coverage information of the terminal device may include one or more of the following information: the signal quality of the terminal device in the serving cell; and the location information of the terminal device in the serving cell.

[0077] In some embodiments, the signal quality of the terminal device in the serving cell may include the RSRP measurement value of the terminal device in the serving cell, or the signal quality of the terminal device in the serving cell may be represented by the RSRP measurement value of the terminal device in the serving cell.

[0078] In some embodiments, the location information of the terminal device in the serving cell may include (or be used to indicate, or be used to determine) the distance between the terminal device and a cell reference point of the serving cell. The cell reference point may be, for example, the center of the cell or the edge of the cell.

[0079] In some embodiments, the location information of the terminal device in the serving cell may include (or be used to indicate, or be used to determine) the distance between the terminal device and the satellite. For example, if the terminal device is in a non-terrestrial network (NTN) cell, the location information of the terminal device in the serving cell may include the distance between the terminal device and the satellite, or the location of the terminal device in the serving cell may be represented by the distance between the terminal device and the satellite.

[0080] In some embodiments, step S610 may be replaced by: the terminal device determines the first transmission resource from one or more transmission resources according to the first configuration information.

[0081] In some embodiments, step S610 may be replaced by: the terminal device determines the first transmission resource from one or more transmission resources based on the first information and the first configuration information.

[0082] In some embodiments, the first configuration information may be used by the terminal device to determine the first transmission resource. For example, the first configuration information may be used to indicate (or determine) a mapping relationship between the one or more transmission resources and the first information.

[0083] Taking the first information as the energy storage related information of the terminal device as an example, the terminal device can select the transmission resource corresponding to its own energy storage related information for transmission according to the mapping relationship indicated by the first configuration information. For example, the terminal device can select PRACH resources with different repetition times based on the currently stored energy. Exemplarily, the more energy the terminal device stores, the PRACH resources with a larger number of repetitions can be selected. For another example, the terminal device can select PRACH resources with different repetition times based on the energy storage capacity of the terminal device. Exemplarily, the stronger the energy storage capacity of the terminal device, the PRACH resources with a larger number of repetitions can be selected.

[0084] Taking the example that the first information includes both the energy storage related information and coverage information of the terminal device, the terminal device can select the transmission resource corresponding to its own energy storage related information and coverage information for transmission according to the mapping relationship indicated by the first configuration information. For example, the terminal device can select PRACH resources with different repetition times based on the current stored energy and RSRP measurement value. Exemplarily, the more energy the terminal device stores and the smaller the RSRP measurement value, the PRACH resource with a larger number of repetitions is selected. For another example, the terminal device can select PRACH resources with different repetition times based on the energy storage capacity of the terminal device and the RSRP measurement value. Exemplarily, the stronger the energy storage capacity of the terminal device and the smaller the RSRP measurement value, the PRACH resource with a larger number of repetitions is selected.

[0085] In some embodiments, the first configuration information may be used to indicate (or determine) a mapping relationship between a characteristic of a transmission resource and the first information. For example, the first configuration information may be used to indicate (or determine) a mapping relationship between one or more MCSs and the first information. For another example, the first configuration information may be used to indicate (or determine) a mapping relationship between one or more repetition times and the first information.

[0086] In some embodiments, the first configuration information may be used to indicate (or to determine) a mapping relationship between multiple MCSs and multiple energy storage related information of the terminal device (such as the energy currently stored in the terminal device).

[0087] In some embodiments, the first configuration information can be used to indicate (or determine) a mapping relationship between multiple repetition times (such as the repetition times of PRACH) and multiple energy storage related information of the terminal device (such as the energy currently stored in the terminal device).

[0088] In some embodiments, the first configuration information can be used to indicate (or to determine) a mapping relationship between multiple repetition times (such as the repetition times of PRACH) and multiple energy storage-related information of the terminal device (such as the energy currently stored in the terminal device) and coverage information (such as RSRP).

[0089] In some embodiments, the first information may correspond to multiple value ranges; the first configuration information may be used to indicate a mapping relationship between the multiple value ranges and multiple transmission resources. For example, the first information may be energy storage-related information (such as the energy currently stored in the terminal device), and the energy storage-related information may correspond to multiple value ranges, and each value range in the multiple value ranges may correspond to at least one transmission resource in the multiple transmission resources. Different value ranges in the multiple value ranges may correspond to the same transmission resource or different transmission resources.

[0090] In some embodiments, the value of the first information (e.g., energy storage-related information) belongs to a first value range among multiple value ranges. The first configuration information can be used to indicate a mapping relationship between the multiple value ranges and the multiple transmission resources, and the first transmission resource is the transmission resource corresponding to the first value range.

[0091] For example, by defining one or more threshold values ​​of energy storage related information, different value ranges of energy storage related information can be mapped to different transmission resources. Exemplarily, N (N is a positive integer) threshold values ​​of energy storage related information can be introduced: W(1), W(2), ..., W(N), where W(n)>W(n+1), and n is any value from 1 to N. The threshold values ​​of the N energy storage related information can divide the values ​​of the energy storage related information into N+1 value ranges. The N+1 value ranges can correspond to N+1 different transmission resources (R(1), R(2), ..., R(N+1)) respectively. When the energy storage related information of the terminal device is greater than W(1), the terminal device can determine the first transmission resource as the transmission resource R(1); when the energy storage related information of the terminal device is between W(n) and W(n+1), the terminal device can determine the first transmission resource as the transmission resource R(n+1); when the energy storage related information of the terminal device is less than W(N), the terminal device can determine the first transmission resource as the transmission resource R(N+1).

[0092] In some embodiments, the first information may correspond to multiple value ranges; in the first configuration information, each value range in the multiple value ranges corresponds to one repetition number (or MCS) among multiple repetition numbers (or MCS). For example, the first information may be energy storage-related information (such as the energy currently stored in the terminal device), and the energy storage-related information may correspond to multiple value ranges, and each value range in the multiple value ranges may correspond to one repetition number (or MCS) among multiple repetition numbers (or MCS). Different value ranges in the multiple value ranges may correspond to the same repetition number (or MCS) or different repetition numbers (or MCS).

[0093] In some embodiments, one or more threshold values ​​of energy storage related information can be defined to map different value ranges of energy storage related information to different transmission resources. For example, N (N is a positive integer) threshold values ​​of energy storage related information can be introduced: W(1), W(2), ..., W(N), where W(n)>W(n+1) and n is any value from 1 to N. The N threshold values ​​of energy storage related information can divide the value of energy storage related information into N+1 value ranges. The N+1 value ranges can correspond to N+1 different repetition times (K(1), K(2), ..., K(N+1)). When the energy storage related information of the terminal device is greater than W(1), the terminal device can determine the repetition time to be K(1); when the energy storage related information of the terminal device is between W(n) and W(n+1), the terminal device can determine the repetition time to be K(n+1); when the energy storage related information of the terminal device is less than W(N), the terminal device can determine the repetition time to be K(N+1).

[0094] In some embodiments, the first information may correspond to multiple value range combinations; and the first configuration information may be used to indicate a mapping relationship between the multiple value range combinations and multiple transmission resources. For example, the first information may include energy storage related information (such as the energy currently stored in the terminal device) and coverage information (such as the RSRP measurement value of the terminal device); the energy storage related information and the coverage information may both correspond to multiple value ranges, and the multiple value range combinations mentioned above may be a combination of multiple value ranges corresponding to the energy storage related information and multiple value ranges corresponding to the coverage information.

[0095] In some embodiments, the value of the first information may include multiple values ​​(such as the value of energy storage related information and the value of coverage information). The multiple values ​​belong to a first value range combination among multiple value range combinations. The first configuration information is used to indicate a mapping relationship between the first value range combination and multiple transmission resources, and the first transmission resource is the transmission resource corresponding to the first value range combination.

[0096] In some embodiments, one or more threshold values ​​of energy storage related information and one or more threshold values ​​of coverage information may be defined, thereby mapping different value ranges of energy storage related information and different value ranges of coverage information to different transmission resources.

[0097] For example, the network device can provide M (M is a positive integer) transmission resources: R(1), R(2), ..., R(M). Furthermore, N (N is a positive integer) threshold values ​​of energy storage related information can be introduced: W(1), W(2), ..., W(N); and X (X is a positive integer) threshold values ​​of coverage information can be introduced: P(1), P(2), ..., P(X). The threshold values ​​of the N energy storage related information can divide the values ​​of the energy storage related information into N+1 value ranges. The threshold values ​​of the X coverage information can divide the values ​​of the coverage information into X+1 value ranges. For the value ranges of the N+1 energy storage related information and the value ranges of the X+1 coverage information, the network device can map one or more value combinations of {value ranges of energy storage related information, value ranges of coverage information} to one transmission resource. The one or more value combinations of {value range of energy storage related information, value range of coverage information} and the transmission resources may be mapped one-to-one or many-to-one.

[0098] For another example, the network device can provide M (M is a positive integer) transmission resources: R(1), R(2), ..., R(M). Furthermore, N (N is a positive integer) threshold values ​​of energy storage related information can be introduced: W(1), W(2), ..., W(N). The threshold values ​​of the N energy storage related information can divide the values ​​of the energy storage related information into N+1 value ranges. For one value range in the N+1 value ranges, a mapping relationship between one or more value ranges of separate coverage information and the transmission resources can be introduced. The value ranges of the coverage information in different value ranges in the N+1 value ranges can be the same, partially the same, or different.

[0099] In some embodiments, the first information may correspond to multiple value range combinations; and in the first configuration information, each value range combination in the multiple value range combinations corresponds to one repetition number (or MCS) among multiple repetition numbers (or MCS). For example, the first information may include energy storage related information (such as the energy currently stored in the terminal device) and coverage information (such as the RSRP measurement value of the terminal device); the energy storage related information and the coverage information may both correspond to multiple value ranges, and the multiple value range combinations mentioned above may be a combination of multiple value ranges corresponding to the energy storage related information and multiple value ranges corresponding to the coverage information.

[0100] In some embodiments, different value ranges of energy storage related information and different value ranges of coverage information can be mapped to different repetition times (or MCS) by defining one or more threshold values ​​of energy storage related information and one or more threshold values ​​of coverage information.

[0101] For example, the network device can provide M (M is a positive integer) transmission resources: R(1), R(2), ..., R(M). Furthermore, N (N is a positive integer) threshold values ​​of energy storage related information can be introduced: W(1), W(2), ..., W(N); and X (X is a positive integer) threshold values ​​of coverage information can be introduced: P(1), P(2), ..., P(X). The threshold values ​​of the N energy storage related information can divide the values ​​of the energy storage related information into N+1 value ranges. The threshold values ​​of the X coverage information can divide the values ​​of the coverage information into X+1 value ranges. For the value ranges of the N+1 energy storage related information and the value ranges of the X+1 coverage information, the network device can map one or more value combinations of {value ranges of energy storage related information, value ranges of coverage information} to a repetition number (or MCS). The value combinations of the one or more {value ranges of the energy storage related information, value ranges of the coverage information} and the number of repetitions (or MCS) may be mapped one-to-one or many-to-one.

[0102] For another example, the network device can provide M (M is a positive integer) transmission resources: R(1), R(2), ..., R(M). Furthermore, N (N is a positive integer) threshold values ​​of energy storage related information can be introduced: W(1), W(2), ..., W(N). The threshold values ​​of the N energy storage related information can divide the values ​​of the energy storage related information into N+1 value ranges. For one value range in the N+1 value ranges, a mapping relationship between one or more value ranges of separate coverage information and the number of repetitions (or MCS) can be introduced. The value ranges of the coverage information in different value ranges in the N+1 value ranges can be the same, partially the same, or different.

[0103] The above text describes the content of the first configuration information in detail with reference to a plurality of embodiments. The following describes the configuration method of the first configuration information with examples.

[0104] In some embodiments, the first configuration information may be pre-configuration information. For example, the terminal device may pre-store the first configuration information in a memory or a tag of the terminal device.

[0105] In some embodiments, the first configuration information may be configuration information sent by a network device. For example, the network device may configure uplink transmission resources for a terminal device and, based on the first configuration information, configure different transmission resources for terminal devices with different energy storage-related information. For another example, the network device may configure uplink transmission resources for a terminal device and, based on the first configuration information, configure different transmission resources for terminal devices with different energy storage-related information and different coverage information.

[0106] In some embodiments, the network device may send the first configuration information to the terminal device via a system message. That is, the first configuration information may be carried in a system message. The system message may be, for example, a system information block (SIB) message or a master information block (MIB) message. Taking the SIB message as an example, the system message may be a SIB1 message or other SIB message.

[0107] In some embodiments, the network device may send the first configuration information via radio resource control (RRC) signaling. That is, the first configuration information may be carried in RRC signaling. The RRC signaling may be, for example, RRC dedicated signaling.

[0108] Taking the first configuration information as the configuration information sent by the network device as an example, referring to Figure 7, an embodiment of the present application also provides a method for wireless communication (or resource configuration method). The method includes step S710, that is, the network device sends the first configuration information to the terminal device (which can be sent in a broadcast manner or directly to the terminal device). In some embodiments, after receiving the first configuration information, the terminal device can continue to perform the above-mentioned step S610.

[0109] In some embodiments, after selecting the first transmission resource, the terminal device may transmit with the network device based on the first transmission resource. Taking the first transmission resource as a PRACH resource with a repetition number of K as an example, the terminal device may access the network device based on the PRACH resource with a repetition number of K.

[0110] In some embodiments, the terminal device mentioned in the embodiments of the present application may refer to a zero-power terminal. The zero-power terminal may be one of Device A, Device B or Device C mentioned in the section "Classification of Zero-Power Terminals". For example, a zero-power terminal may not have an energy storage function, and may not have independent signal generation and signal amplification functions, and may only rely on backscatter communication to send signals. For another example, a zero-power terminal may have an energy storage function, but may not be able to generate signals independently, and may only use backscattering to send signals. The energy stored in the zero-power terminal can be used to amplify the reflected scattered signal. For another example, the zero-power terminal can generate signals independently, that is, the zero-power terminal can actively send signals. As an example, the zero-power terminal may be a radio frequency identification (RFID) tag. Accordingly, the network device may be an RFID reader.

[0111] The following describes the embodiments of the present application in more detail with reference to specific examples. In the following examples, the terminal device mentioned above is a zero-power terminal, the first configuration information is the configuration information sent by the network device, and the transmission resources are PRACH resources with different repetition times. It should be understood that the following examples are only intended to help those skilled in the art understand the embodiments of the present application, and are not intended to limit the embodiments of the present application to the specific numerical values ​​or specific scenarios illustrated. It is obvious that those skilled in the art can make various equivalent modifications or changes based on the examples below, and such modifications or changes also fall within the scope of the embodiments of the present application.

[0112] Example 1: The first information is energy-related information of a zero-power terminal

[0113] For zero-power terminals with different energy storage-related information, the network device configures PRACH resources with different repetition times. Then, the network device can notify the zero-power terminal of the mapping relationship between its energy storage-related information and the repetition times of the PRACH resources through the first configuration information. After receiving the first configuration information, the zero-power terminal can select the corresponding PRACH resource for transmission based on its own energy storage-related information. For example, the zero-power terminal can select a PRACH resource with a corresponding number of repetitions based on the currently stored energy. Exemplarily, the more energy the zero-power terminal stores, the zero-power terminal device can select a PRACH resource with a larger number of repetitions. For another example, the zero-power terminal can select a PRACH resource with a corresponding number of repetitions based on the energy storage capacity of the zero-power terminal. Exemplarily, the stronger the energy storage capacity of the zero-power terminal, the zero-power terminal device can select a PRACH resource with a larger number of repetitions.

[0114] Zero-power terminals with different energy storage may support different coverage. For example, the less energy a zero-power terminal stores, the fewer PRACH repetitions it supports. Otherwise, a large number of repetitions may exhaust the energy stored in the zero-power terminal. When configuring PRACH resources, network equipment takes into account the differences in energy storage among different zero-power terminals. This allows network equipment to more flexibly support the access of zero-power terminals with different energy storage capabilities, thereby helping to increase the possibility of zero-power terminals with different energy storage capabilities accessing the network for data transmission.

[0115] Example 2: The first information includes energy-related information and coverage information of the zero-power terminal

[0116] For zero-power terminals with different energy storage-related information and coverage information, the network device configures PRACH resources with different repetition times. Then, the network device can notify the zero-power terminal of the mapping relationship between energy storage-related information, coverage information and the number of repetitions of PRACH resources through the first configuration information. After receiving the first configuration information, the zero-power terminal can select PRACH resources with corresponding repetition times based on its own energy storage-related information and coverage information (such as RSRP measurement amount). For example, the more energy the zero-power terminal stores and the smaller the RSRP measurement value, the PRACH resource with a larger number of repetitions is selected. For another example, the stronger the energy storage capacity of the zero-power terminal and the smaller the RSRP measurement value, the PRACH resource with a larger number of repetitions is selected.

[0117] Zero-power terminals with different energy storage may support different coverage. For example, the less energy a zero-power terminal stores, the fewer PRACH repetitions it supports. Otherwise, a large number of repetitions may exhaust the energy stored in the zero-power terminal. When configuring PRACH resources, network devices take into account the differences in energy storage among different zero-power terminals, allowing network devices to more flexibly support the access of zero-power terminals with different energy storage capabilities, thereby helping to increase the possibility of zero-power terminals with different energy storage capabilities accessing the network for data transmission. In addition, considering the network coverage of zero-power terminals while considering energy storage-related information can, on the one hand, avoid wasting transmission resources, and on the other hand, avoid excessive power consumption caused by excessive repetitions. For example, if the coverage of a terminal device is good, even if the terminal device currently stores a large amount of energy, it can select a transmission resource with a lower number of repetitions, thereby avoiding wasting resources and, on the other hand, avoiding excessive power consumption caused by excessive retransmissions.
