[0054] To facilitate understanding of the technical solutions of the embodiments of the present application, the relevant technologies of the present application are explained.

[0055] 1. Zero-power communication

[0056] The key technologies of zero-power communication include energy harvesting, backscatter communication and low-power technology.

[0057] As shown in Figure 2, a typical zero-power communication system (such as an RFID system) includes a network device (such as an RFID system reader) and a zero-power device (such as an electronic tag). The network device is used to send wireless power supply signals and downlink communication signals to the zero-power device and receive backscattered signals from the zero-power device. A basic zero-power device includes an energy harvesting module, a backscatter communication module, and a low-power computing module. In addition, the zero-power device may also have a memory or sensor for storing some basic information (such as item identification, etc.) or sensor data such as ambient temperature and ambient humidity.

[0058] For example, the energy harvesting module can collect energy carried by radio waves in space (Figure 2 shows radio waves emitted by network devices) to drive the low-power computing module of the zero-power device and implement backscatter communication. After obtaining energy, the zero-power device can receive control commands from the network device and send data to the network device based on control signaling using backscattering. The data sent can be data stored in the zero-power device itself (such as an identity identifier or pre-written information, such as the product's production date, brand, manufacturer, etc.). The zero-power device can also be loaded with various sensors, so that the data collected by various sensors can be reported based on the zero-power mechanism.

[0059] The following describes the key technologies in zero-power communication.

[0060] 1. RF Power Harvesting

[0061] As shown in Figure 3, the RF energy harvesting module uses the principle of electromagnetic induction to harvest electromagnetic wave energy from space, thereby obtaining the energy needed to operate zero-power devices. This energy is used to drive low-power demodulation and modulation modules, sensors, and memory readout. Therefore, zero-power devices do not require traditional batteries.

[0062] 2. Back Scattering

[0063] As shown in Figure 4, a zero-power device receives a carrier signal sent by a network device, modulates it, loads the information to be transmitted, and radiates the modulated signal from the antenna. This information transmission process is called backscatter communication. Backscatter and load modulation are closely related. Load modulation achieves this by adjusting and controlling the circuit parameters of the zero-power device's oscillator circuit according to the data stream's rhythm, causing parameters such as the zero-power device's impedance to change accordingly. Load modulation techniques primarily include resistive load modulation and capacitive load modulation. In resistive load modulation, a resistor is connected in parallel with the load, which is turned on or off based on the binary data stream, as shown in Figure 5. The switching of the resistor causes a change in the circuit voltage, thus implementing amplitude-shifted keying (ASK) modulation. This modulation and transmission is achieved by adjusting the amplitude of the zero-power device's backscattered signal. Similarly, in capacitive load modulation, the switching of the capacitor changes the circuit's resonant frequency, enabling frequency-shifted keying (FSK) modulation. This modulation and transmission is achieved by adjusting the operating frequency of the zero-power device's backscattered signal.

[0064] It can be seen that the zero-power device uses load modulation to modulate the incoming signal, thereby realizing the backscatter communication process. Therefore, the zero-power device has significant advantages:

[0065] (1) It does not actively transmit signals, so it does not require complex RF links, such as PA, RF filters, etc.

[0066] (2) There is no need to actively generate high-frequency signals, so no high-frequency crystal oscillator is required;

[0067] (3) With the help of backscatter communication, terminal signal transmission does not need to consume the terminal's own energy.

[0068] 3. Coding technology

[0069] Data transmitted by zero-power devices can use various codes to represent binary "1s" and "0s." RFID systems typically use one of the following encoding methods: non-return-to-zero (NRZ), Manchester, unipolar return-to-zero, differential bi-phase (DBP), differential, pulse interval encoding (PIE), bidirectional space encoding (FMO), Miller, and differential encoding. In simple terms, different encoding techniques use different pulse signals to represent 0s and 1s.

[0070] In some scenarios, based on the energy source and usage of zero-power devices, zero-power devices can be divided into the following types:

[0071] 1. Passive zero-power devices

[0072] Zero-power devices (such as electronic tags in RFID systems) do not require internal batteries. When a zero-power device is close to a network device (such as an RFID reader), it is within the near-field radiation generated by the network device's antenna. Consequently, the zero-power device's antenna generates an induced current through electromagnetic induction, which drives the device's low-power chip circuitry. This enables forward link signal demodulation and reverse link (or reflection link) signal modulation. For backscatter links, the zero-power device uses backscattering to transmit signals.

[0073] It can be seen that the passive zero-power device does not require a built-in battery to drive either the forward link or the reverse link, and is a truly zero-power device.

[0074] Passive zero-power devices do not require batteries, and the RF circuit and baseband circuit are very simple. For example, they do not require low-noise amplifiers (LNAs), power amplifiers (PAs), crystal oscillators, analog-to-digital converters (ADCs), and other devices. Therefore, they have many advantages such as small size, light weight, very low price, and long service life.

[0075] Passive zero-power terminals can also support other energy collection methods. By collecting energy from the environment (such as light energy, thermal energy, kinetic energy, mechanical energy, etc.), they can obtain energy for driving circuits and support terminal devices to communicate.

[0076] 2. Semi-passive zero-power devices

[0077] Semi-passive zero-power devices do not have conventional batteries installed themselves, but can use RF energy harvesting modules to harvest radio wave energy or use energy harvesting modules to harvest energy from the environment (such as solar energy, thermal energy, mechanical vibration energy, etc.), and store the harvested energy in an energy storage unit (such as a capacitor). After the energy storage unit obtains energy, it can drive the low-power chip circuit of the zero-power device. It can realize tasks such as demodulation of forward link signals and modulation of reverse link signals. For backscatter links, zero-power devices use backscatter implementation to transmit signals. Alternatively, based on the harvested energy, zero-power devices can use low-power transmitters for active transmission communication.

[0078] It can be seen that the semi-passive zero-power device does not require a built-in battery to drive either the forward link or the reverse link. Although it uses energy stored in capacitors during operation, the energy comes from the radio energy collected by the energy harvesting module. Therefore, it is also a truly zero-power device.

[0079] Semi-passive zero-power devices inherit many advantages of passive zero-power devices, so they have many advantages such as small size, light weight, very low price, and long service life.

[0080] 3. Active zero-power devices

[0081] In some scenarios, zero-power devices can also be active zero-power devices, which can have built-in batteries. The batteries power the low-power chip circuitry in these devices, enabling forward link signal demodulation and reverse link signal modulation. However, for backscatter links, zero-power devices use backscattering to transmit signals. Therefore, the zero-power nature of these devices lies primarily in the fact that reverse link signal transmission does not require the terminal's own power, but rather utilizes backscattering.

[0082] Active zero-power terminals have built-in batteries that power the RFID chip, increasing their read and write distance and improving communication reliability. Therefore, they are suitable for scenarios with relatively high requirements for communication distance and read latency.

[0083] In some scenarios, zero-power devices can be categorized as follows based on transmitter type:

[0084] 1) Zero-power devices based on backscattering

[0085] These zero-power devices use the aforementioned backscattering method to transmit uplink data. These devices lack an active transmitter, only a backscattering transmitter. Therefore, when these zero-power devices transmit data, they require network equipment to provide a carrier, which they then use to perform backscattering to achieve data transmission.

[0086] 2) Zero-power devices based on active transmitters

[0087] This type of zero-power device uses an active transmitter with active transmission capabilities for uplink data transmission. Therefore, when sending data, this type of zero-power device can use its own active transmitter to send data without the need for network equipment to provide a carrier. Active transmitters suitable for zero-power devices can include ultra-low-power ASK and ultra-low-power FSK transmitters. When transmitting a 100uW signal, the overall power consumption can be reduced to 400-600uW.

[0088] 3) Zero-power devices with both backscatter transmitters and active transmitters

[0089] These zero-power devices can support both backscatter and active transmitters. They can determine which signal transmission method to use, namely, active or backscatter, based on different conditions (such as battery life and available ambient energy) or based on network device scheduling.

[0090] In some scenarios, zero-power terminals can be divided into the following three categories based on their energy storage capacity and the ability to generate RF signals:

[0091] Device A: It lacks energy storage capabilities, independent signal generation, and signal amplification functions, and its signal transmission relies solely on backscattering.

[0092] Device B: It has energy storage capabilities but cannot generate signals independently. It can only send signals using backscattering. The stored energy can be used to amplify the reflected signal.

[0093] Device C: Has energy storage capabilities and can independently generate signals, that is, it can actively send signals.

[0094] The zero-power Internet of Things (IoT) can also be referred to as the ambient power enabled IoT (Ambient IoT or AMP IoT). Zero-power devices are also called Ambient IoT devices or AMP IoT devices. Ambient IoT devices can refer to IoT devices that use various ambient energies, such as radio frequency energy, light energy, solar energy, thermal energy, and mechanical energy. These devices can have no energy storage capacity or very limited energy storage capacity, such as using capacitors with a capacity of tens of microfarads.

[0095] Ambient IoT can be used in at least four scenarios:

[0096] 1. Object recognition, such as logistics, production line product management, and supply chain management;

[0097] 2. Environmental monitoring, such as temperature, humidity, and harmful gas monitoring of the working environment and natural environment;

[0098] 3. Positioning, such as indoor positioning, intelligent object search, production line item positioning, etc.

[0099] 4. Intelligent control, such as intelligent control of various electrical appliances in smart homes (turning on and off air conditioners, adjusting temperature), and intelligent control of various facilities in agricultural greenhouses (automatic irrigation and fertilization).

[0100] To facilitate understanding of the technical solutions of the embodiments of the present application, the mobility management related to the present application is explained.

[0101] In the NR system, the mobility management of the terminal mainly includes the cell selection and reselection process in the RRC idle (RRC_IDLE) state or the RRC inactive (RRC_INACTIVE) state.

[0102] During cell selection, the selected cell must meet the S criterion. That is, the cell's signal reception power and signal reception quality must simultaneously meet the following conditions:

[0103] S rxlev >0, and S qual >0 (if Q qualmin ),

[0104] Among them, S rxlev =Q rxlevmeas -(Q rxlevmin +Q rxlevminoffset )-P compensation -Q offsettemp ,

[0105] S qual =Q qualmeas -(Q qualmin +Q qualminoffset )-Q offsettemp ,

[0106] S rxlev and S qual Respectively represent the signal reception level value and signal reception quality value used for cell selection;

[0107] Q rxlevmeas and Q qualmeas Respectively represent the signal reception power (e.g., Reference Signal Receiving Power (RSRP)) and signal reception quality (e.g., Reference Signal Receiving Quality (RSRQ)) of the measured cell;

[0108] Q rxlevmin and Q qualmin They represent the minimum signal receiving power and minimum signal receiving quality required by the network device side respectively;

[0109] Q rxlevminoffset , the offset of the signal receiving power is used to prevent the ping-pong effect between two PLMNs due to radio environment fluctuations;

[0110] Q qualminoffsetThe offset of the signal reception quality is used to prevent the ping-pong effect between two PLMNs due to fluctuations in the radio environment;

[0111] Q offsettemp Indicates a temporary offset, for example, only used in special scenarios, such as the "Chiba Problem" scenario. The Chiba Problem may include a lake with no obstruction and low path loss, resulting in a very long downlink coverage area, while the terminal uplink transmit power is low, resulting in asymmetric uplink and downlink coverage.

[0112] After the terminal successfully camps on a cell, it will continue to measure the cell. For example, the RRC layer of the terminal calculates Srxlev based on the reference signal receiving power (RSRP) measurement result of the cell and compares it with the same frequency measurement start threshold (S intrasearch ) and the non-co-frequency measurement start threshold (i.e. S nonintrasearch , or called the hetero-frequency / hetero-system measurement start threshold) comparison as the decision condition for whether to start neighboring cell measurement.

[0113] 1. For the start of the same-frequency measurement, when the serving cell S rxlev >S IntraSearchP And the serving cell S qual >S IntraSearchQ When the same-frequency neighboring area measurement is started, the same-frequency neighboring area measurement is not started; otherwise, the same-frequency neighboring area measurement is started.

[0114] 2. For inter-frequency measurements with the same priority or lower priority, when the serving cell S rxlev >S nonIntraSearchP And the serving cell S qual >S nonIntraSearchQ When the inter-frequency measurement with the same priority or lower priority is started, the inter-frequency measurement with the same priority or lower priority is not started; otherwise, the inter-frequency measurement with the same priority or lower priority is started.

[0115] 3. For high-priority inter-frequency measurement, always start the high-priority inter-frequency measurement.

[0116] Cell reselection refers to the process by which a terminal, in Radio Resource Control (RRC) idle (RRC_IDLE) mode, selects the best cell to provide service by monitoring the signal quality of neighboring cells and the current cell (also known as the serving cell or source cell). If the signal quality and level of a neighboring cell meet the S criterion and certain reselection criteria (i.e., the R criterion), the terminal will camp on that cell.

[0117] The terminal performs cell reselection based on the measurement results of the neighboring cells:

[0118] 1. For cell reselection of same-frequency cells and inter-frequency cells of the same priority, the R criteria (for example, sorted by RSRP) must be met, the signal quality of the new cell must be better than that of the source cell for a specified period of time, and the UE must reside in the source cell for at least a certain period of time, for example, 1 second.

[0119] 2. For reselection of a high-priority cell, the signal quality of the high-priority cell must be higher than a certain threshold and last for a specified time, and the UE must stay in the source cell for no less than a certain time, such as 1 second.

[0120] 3. For reselection of a low-priority cell, there must be no high-priority cell, the cell with the same priority must meet the requirements, the source cell signal quality must be below a certain threshold, the low-priority cell signal quality must be above a certain threshold and last for a certain period of time, and the UE must stay in the source cell for no less than a certain period of time, for example, 1 second.

[0121] In some scenarios, two sets of measurement relaxation criteria are introduced for the mobility management of non-connected terminal devices, namely the "terminal is not located at the cell edge (Not-cell-edge)" criterion and the "low-mobility (Low-mobility)" criterion.

[0122] For low-mobility terminals, when the RSRP of the serving cell changes little, it means that the terminal has little need to reselect the cell. Therefore, the neighboring cell measurement can be relaxed to achieve the purpose of terminal energy saving.

[0123] For example, in the system message, configure S SearchDeltaP This means that the cell supports the terminal to relax neighboring cell measurement. The terminal can relax neighboring cell measurement if and only if the following conditions are met:

[0124] For example, in the time range T SearchDeltaP Within, the neighboring area satisfies the following measurement relaxation conditions;

[0125] (S rxlevRef -S rxlev ) SearchDeltaP

[0126] Among them, S rxlev is the current Srxlev measurement value of the serving cell, S rxlevRef It is the reference Srxlev value of the serving cell.

[0127] In some scenarios, when the UE selects or reselects to a new cell, or if S rxlevRef -S rxlev >0, or, if T SearchDeltaP If the measurement conditions are not met within the specified time, the UE will rxlevRef Set to the current Srxlev measurement value of the serving cell.​

[0128] In some scenarios, when the not-cell-edge criterion is met, the terminal may relax the requirement to perform neighbor cell measurements.

[0129] For example, the not-cell-edge criterion could be:

[0130] S rxlev >S SearchThresholdP And S qual >S SearchThresholdQ (If the network configuration S SearchThresholdQ ).

[0131] In some scenarios, the terminal can perform cell measurement according to the measurement configuration. For example, the network equipment can configure the synchronization block measurement timing configuration (SS / PBCH block measurement timing configuration, SMTC) corresponding to each frequency point (per frequency) for intra-frequency and inter-frequency to assist the UE in measurement and achieve the purpose of UE power saving.

[0132] In some embodiments, the terminal device may determine the signal quality of the cell based on the parameter N and the threshold. For example, the signal quality of the cell may be the linear average of the signal qualities of the best N beams that meet the threshold.

[0133] In some cases, the parameter N and the threshold may be acquired through system broadcast.

[0134] In other cases, if the system does not broadcast the parameter N and the threshold, the signal quality of the best beam in the cell may be determined as the signal quality of the cell.

[0135] In some scenarios, the terminal can select a candidate cell through rangeToBestCell, that is, among all candidate cells whose signal quality difference with the best cell is within the range rangeToBestCell, the cell with the most beams that meet the threshold is selected as the candidate cell. In some scenarios, in order to achieve the purpose of load balancing of different frequencies, the network side can set the priority of different frequencies. The UE preferentially resides on the high-priority frequency. The frequency priority can be obtained from the system broadcast, from dedicated signaling (such as RRC Release message), or inherited from other RATs.

[0136] In some scenarios, network devices use both cell reselection priority and sub-priority to indicate the final cell reselection frequency priority. Cell reselection priority ranges from 0 to 7, and sub-priority can range from {0.2, 0.4, 0.6, 0.8}, indicating a total of 40 frequency priorities. Sub-priority is only used for NR and LTE frequencies.

[0137] In some scenarios, priority usage follows the following rules:

[0138] If you have a dedicated configuration, you don’t need to broadcast the configuration;

[0139] Stay in any cell state and use broadcast configuration;

[0140] If no priority is configured, the default is the lowest;

[0141] Frequencies between RATs are not configured with the same frequency priority.

[0142] All parameters used to constrain UE measurement behavior in the RRC idle state come from system broadcast messages. It is assumed that all relevant parameters have been configured. If not, the relevant constraints do not exist.

[0143] As can be seen from the preceding description, zero-power terminals offer numerous advantages, including the absence of conventional batteries, maintenance-free operation, compact size, low complexity, low cost, and long lifespan. Their capabilities differ significantly from those of traditional terminals. For example, zero-power terminals require energy harvesting to power themselves. Different terminals may have varying energy harvesting efficiencies, and the coverage supported by the harvested energy may also vary. For example, some terminals can only operate their energy harvesting modules when the received signal power is sufficiently high. This results in differences in cell selection between zero-power terminals with different energy harvesting efficiencies. Furthermore, for Type A zero-power terminals, the backscatter link also requires a received signal to activate. Zero-power terminals with different capabilities may require different received signal strengths to activate the backscatter link. Therefore, managing the mobility of zero-power terminals is an urgent issue that needs to be addressed.

[0159] In some embodiments, AMP devices may be divided into multiple types according to their capabilities, or in other words, the capabilities of AMP devices may be divided into multiple capability levels.

[0160] In some embodiments, the capabilities of the AMP device include, but are not limited to, one or more of the following:

[0161] The transmitter type of the AMP device, whether the AMP device supports backscattering, whether the AMP device supports active transmission, whether the AMP device supports reverse amplification, the reverse amplification capability of the AMP device, whether the AMP device has energy storage capability, the energy storage capability level of the AMP device, and the energy type used by the AMP device for energy harvesting.

[0165] Method 1: Classify AMP devices based on transmitter type or signal transmission method.

[0166] As an example, AMP devices can be divided into:

[0167] AMP devices that support backscatter (or, AMP devices based on backscatter), AMP devices that support active transmission (or, AMP devices based on active transmission).

[0168] As another example, AMP devices can be divided into:

[0169] AMP devices that support backscatter (or, AMP devices based on backscatter), AMP devices that support active transmission (or, AMP devices based on active transmission), AMP devices that support backscatter and active transmission (or, AMP devices based on active transmission and backscatter).

[0171] Optionally, the backscatter capability of an AMP device can be further broken down into:

[0180] Optionally, AMP devices with energy storage capabilities may be divided into multiple levels, for example, based on the energy storage capacity of energy storage units (eg, capacitors) of the AMP devices.

[0181] For example, an AMP device with a first energy storage capacity and an AMP device with a second energy storage capacity, wherein the first energy storage capacity and the second energy storage capacity are different, for example, the first energy storage capacity and the second energy storage capacity correspond to different capacitance capacities or correspond to different capacitance capacity ranges, such as the first energy storage capacity corresponds to a small capacitance capacity, and the second energy storage capacity corresponds to a large capacitance capacity.

For example, the first energy storage capacity corresponds to a small capacitance capacity, the second energy storage capacity corresponds to a medium capacitance capacity, and the third energy storage capacity corresponds to a large capacitance capacity.

[0183] Method 3: Classify AMP devices according to their energy sources.

[0184] As an example, AMP devices can be divided into:

[0185] AMP devices based on radio frequency energy, and AMP devices based on non-radio frequency energy (i.e., using other environmental energy besides radio frequency energy, such as one or more of light, heat, vibration, etc.).

[0186] As another example, AMP devices can be divided into:

[0187] AMP devices based on radio frequency energy, AMP devices based on light energy, AMP devices based on mechanical energy, and AMP devices based on other environmental energy.

[0188] It should be understood that the above-described classification or capability division of AMP devices is merely an example, and the present application is not limited thereto. AMP devices may also be classified in other ways. For example, AMP devices may be divided into three categories based on their energy storage capacity and whether they support active transmission: Device A, Device B, and Device C. The capabilities corresponding to Device A, Device B, and Device C are described in detail in the previous embodiment and are not further detailed here for the sake of brevity.

[0189] In some embodiments, the target operation includes an operation related to mobility management. The mobility management may include, but is not limited to, mobility management in RRC idle or RRC inactive states, such as operations related to cell selection or cell reselection, or mobility management in RRC connected states, such as operations related to cell handover.

[0190] In some specific embodiments, the target operation includes but is not limited to one or more of the following operations:

[0191] Cell selection, cell reselection, starting neighbor cell measurement, relaxing neighbor cell measurement, and determining whether the cell is not at the cell edge.

[0192] That is, the target parameters may include one or more of the parameters used by the target AMP device to perform cell selection, parameters for performing cell reselection, parameters for starting neighboring cell measurement, parameters for relaxing neighboring cell measurement, and parameters for determining whether it is at the edge of a cell.

[0193] In some embodiments of the present application, the target parameters are predefined.

[0194] For example, all AMP devices can be predefined to use a unified set of parameters to perform the target operation, or AMP devices can be divided into multiple capabilities or multiple types, each capability or type corresponds to a set of parameters. In this case, the target parameters can be a set of parameters corresponding to the capabilities of the target AMP device.

[0195] In other embodiments of the present application, the target parameter may be configured by a network device, for example, via a system message or RRC signaling.

[0196] For example, a network device may configure all AMP devices to perform target operations using a unified set of parameters, or AMP devices may be divided into multiple capabilities or types, with each capability or type configured with a set of parameters. In this case, the target parameters may be a set of parameters corresponding to the capabilities of the target AMP device.

[0197] In some further embodiments of the present application, the target parameter is determined by the target AMP device.

[0198] For example, the target AMP device may determine the target parameter based on a reference parameter, wherein the reference parameter is a parameter used by the reference device to perform the target operation.

[0199] In some embodiments, the reference parameters may include one or more of parameters for performing cell selection on a reference device, parameters for performing cell reselection, parameters for starting neighbor cell measurements, parameters for relaxing measurements on neighbor cells, and parameters for determining whether the device is at the cell edge.

[0200] In some embodiments, the reference parameter may be considered to be a parameter corresponding to a reference device capability or a reference device type, where the reference device capability is a capability corresponding to the reference device, and the reference device type is a device type corresponding to the reference device.

[0201] In some embodiments, the reference device is a non-AMP device (or a traditional terminal), or it can also be a reference AMP device. The reference AMP device can be, for example, an AMP device with a specific capability. The capability of the reference AMP device is also called a reference capability. In some embodiments, the reference capability can be characterized by the energy harvesting-related capability and / or the backscattering-related capability of the reference AMP device. For example, the reference capability can be characterized by the minimum signal reception power and / or minimum signal reception quality required for the reference AMP device to start the energy harvesting module or perform energy harvesting, and / or the minimum signal reception power and / or minimum signal reception quality required for the reference AMP device to start the backscattering module or perform backscattering.

[0202] In some embodiments, reference parameters corresponding to the reference capability may be predefined or configured by the network (e.g., via system messages), wherein the reference capability corresponds to a specific minimum RSRP and / or minimum RSRQ required to enable an energy harvesting module or perform an energy harvesting operation, and / or a specific minimum RSRP and / or minimum RSRQ required to enable a backscattering module or perform a backscattering operation.

[0203] In some embodiments, the reference parameter is predefined or configured by a network device, for example, via a system message or RRC signaling.

[0204] In some embodiments, the target parameter is determined based on the reference parameter, including:

[0205] The target parameter is determined based on the reference parameter and a target offset, wherein the target offset is determined based on a capability difference between the target AMP device and the reference device. For example, the target parameter is equal to the sum of the reference parameter and the target offset.

[0206] In some embodiments, the target offset is determined by the target AMP device based on a capability difference between the target AMP device and the reference device. That is, the network device does not need to be configured with the target offset; the target offset is determined by the target AMP device based on the capability difference between the target AMP device and the reference device.

[0207] In some embodiments, the target offset is selected by the target AMP device at M offsets, wherein the M offsets correspond to M types of AMP device capabilities, and the M offsets are the offsets between the parameters corresponding to the M types of AMP device capabilities for performing the target operation relative to the parameters corresponding to the reference AMP device capabilities for performing the target operation (i.e., reference parameters), and the target offset is the offset corresponding to the capability of the target AMP device, and M is a positive integer.

[0208] That is, in this case, the target AMP device can determine the target offset from the M offsets according to its own capabilities, and further determine the target parameter in combination with the reference parameter.

[0209] In some embodiments, the M offsets are predefined or configured by a network device, for example, via a system message or RRC signaling.

[0210] In some embodiments, the target parameter is one of a plurality of sets of parameters, each of which corresponds to a different AMP device capability, each set of parameters including parameters for an AMP device with a corresponding capability to perform the target operation. The target parameter is a set of parameters corresponding to the capability of the target AMP device.

[0211] That is, in this case, the target AMP device can determine a set of parameters from multiple sets of parameters according to its own capabilities, and this set of parameters is the target parameters.

[0212] In some embodiments, different AMP device capabilities correspond to different information including one or more of the following:

[0213] The minimum signal receiving power required to start the energy harvesting module or perform energy harvesting;

[0214] The minimum signal reception quality required to start the energy harvesting module or perform energy harvesting;

[0215] The minimum signal receiving power required to start the backscatter module or perform backscattering;

[0216] The minimum signal reception quality required to start the backscatter module or perform backscattering.

[0217] In some embodiments, the multiple groups of parameters are predefined or configured by the network device, for example, via system messages or RRC signaling.

[0218] In some embodiments of the present application, the method 200 further includes:

[0219] The network device sends first information to the target AMP device, where the first information is used to determine the target parameter.

[0220] In some embodiments, the first information is used to indicate multiple groups of parameters, the target parameter is one of the multiple groups of parameters, the multiple groups of parameters correspond to different AMP device capabilities, and each group of parameters includes parameters for the AMP device with corresponding capabilities to perform the target operation.

[0221] In some other embodiments, the first information is used to indicate a reference parameter and M offsets, wherein the reference parameter is a parameter used by a reference device to perform a target operation, and the reference device may be a traditional terminal or a reference AMP device.

[0222] For example, the M offsets correspond to M AMP device capabilities, and the M offsets correspond to M AMP device capabilities. The M offsets are offsets between parameters corresponding to the M AMP device capabilities for performing the target operation relative to parameters corresponding to the reference AMP device capabilities for performing the target operation. In this case, the target AMP device can select a target offset from the M offsets based on its own capabilities.

[0223] In some embodiments, the first information indicates reference parameters, and the target parameters are determined based on the reference parameters, wherein the reference parameters include parameters for a reference device to perform the target operation, wherein the reference device is a non-AMP device or a reference AMP device. In this case, the target AMP device may determine a target offset based on a difference between its own capabilities and those of the reference device.

[0224] In some embodiments, the first information may be carried via downlink signaling such as system messages and RRC signaling.

[0225] The following describes the mobility management method of the AMP device provided in the embodiment of the present application in combination with specific scenarios.

[0226] Example 1: Target operation includes cell selection

[0227] In this embodiment 1, the target parameters include parameters for cell selection.

[0228] In some embodiments, the target parameter includes a target signal received power related parameter and / or a target received signal quality related parameter.

[0229] The target signal received power related parameters are used to determine a signal received level value for cell selection corresponding to the signal received power of the cell measured by the target AMP device, that is, Srxlev.

[0230] The target signal reception quality related parameter is used to determine a signal reception quality value for cell selection corresponding to the signal reception quality of the cell measured by the target AMP device, that is, Squal.

[0231] In some embodiments, the minimum signal reception quality Q required by the network device is configured. qualmin In the case of the target parameters including the target signal receiving power related parameters and the target receiving signal quality related parameters, when the minimum signal receiving quality Q required by the network device is not configured qualmin In this case, the target parameters include parameters related to the target signal receiving power.

[0232] In some embodiments, the target signal received power related parameters include a target signal received power compensation parameter, which is used to compensate for the signal received power of the cell measured by the target AMP device.

[0233] In some embodiments, the target signal reception quality related parameter includes a target signal reception quality compensation parameter, which is used to compensate for the signal reception quality of the cell measured by the target AMP device.

[0234] Hereinafter, a method for determining a target RSRP compensation parameter and a target RSRQ compensation parameter will be described by taking the signal received power as RSRP and the signal received quality as RSRQ as an example.

[0235] Method 1:

[0236] In some embodiments, the target RSRP compensation parameter is determined according to a reference RSRP compensation parameter, and the reference RSRP compensation parameter is an RSRP compensation parameter corresponding to a legacy terminal.

[0237] For example, the target RSRP compensation parameter is determined according to the reference RSRP compensation parameter and the capability difference between the target AMP device and the legacy terminal.

[0238] In some embodiments, the reference RSRP compensation parameter may include the minimum RSRP required by the network device side for the traditional terminal, that is, Q rxlevmin The target RSRP compensation parameter may be equivalent to the minimum RSRP required by the network device for the target AMP device.

[0239] In some embodiments, the target RSRP compensation parameter is determined based on a reference RSRP compensation parameter and a target RSRP offset, wherein the target RSRP offset is determined based on a capability difference between the target AMP device and the reference AMP device. For example, the target RSRP compensation parameter is equal to the sum of the reference RSRP compensation parameter and the target RSRP offset.

[0240] In some embodiments, the target RSRP offset may be determined based on an RSRP offset related to the energy harvesting capability of the target AMP device and / or an RSRP offset related to the backscattering capability of the target AMP device.

[0241] For example, the target RSRP offset can be equal to the sum of the RSRP offset related to the energy harvesting capability of the target AMP device and the RSRP offset related to the backscattering capability of the target AMP device, or it can be equal to the RSRP offset related to the energy harvesting capability of the target AMP device, or it can be equal to the RSRP offset related to the backscattering capability of the target AMP device, or it can be equal to the larger or smaller value of the two RSRP offsets.

[0242] As an example, if the target AMP device supports energy harvesting and supports active transmission but does not support backscattering, the target RSRP offset may be an RSRP offset related to the energy harvesting capability of the target AMP device.

[0243] As another example, if the target AMP device supports both energy harvesting and backscattering, the target RSRP offset may be equal to the sum of the two RSRP offsets, or equal to one of the RSRP offsets, or equal to the larger or smaller of the two.

[0244] Optionally, the RSRP offset related to the energy harvesting capability of the target AMP device may be the difference between the minimum RSRP required for the target AMP device to start the energy harvesting module or perform the energy harvesting operation and the minimum RSRP required by the network device side for the traditional terminal.

[0245] For example, the minimum RSRP required by the network device for traditional terminals is x0dBm, and the minimum RSRP required for the target AMP device to start the energy harvesting module or perform energy harvesting operations is x1dBm. Then the RSRP offset related to the energy harvesting capability of the target AMP device is (x1-x0)dB.

[0246] Optionally, the RSRP offset associated with the backscatter capability of the target AMP device may be a difference between a minimum RSRP required for the target AMP device to start a backscatter module or perform a backscatter operation and a minimum RSRP required by the network device side.

[0247] For another example, the minimum RSRP required by the network device for traditional terminals is y0dBm, and the minimum RSRP required by the target AMP device to start the backscatter module or perform backscatter operations is y1dBm. Then the RSRP offset related to the backscatter capability of the target AMP device is (y1-y0)dB.

[0248] In some embodiments, the target RSRQ compensation parameter is determined according to a reference RSRQ compensation parameter, and the reference RSRQ compensation parameter is an RSRQ compensation parameter corresponding to a legacy terminal.

[0249] For example, the target RSRQ compensation parameter is determined according to the reference RSRQ compensation parameter and the capability difference between the target AMP device and the legacy device.

[0250] In some embodiments, the reference RSRQ compensation parameter may include the minimum RSRQ required by the network device side for the traditional terminal, that is, Q qualmin The target RSRQ compensation parameter may be equivalent to the minimum RSRQ required by the network device for the target AMP device.

[0251] In some embodiments, the target RSRQ compensation parameter is determined based on a reference RSRQ compensation parameter and a target RSRQ offset, wherein the target RSRQ offset is determined based on a capability difference between the target AMP device and the reference AMP device. For example, the target RSRQ compensation parameter is equal to the sum of the reference RSRQ compensation parameter and the target RSRQ offset.

[0252] In some embodiments, the target RSRQ offset may be determined based on an RSRQ offset associated with an energy harvesting capability of the target AMP device and / or an RSRQ offset associated with a backscattering capability of the target AMP device.

[0253] For example, the target RSRQ offset can be equal to the sum of the RSRQ offset related to the energy harvesting capability of the target AMP device and the RSRQ offset related to the backscattering capability of the target AMP device, or it can be equal to the RSRQ offset related to the energy harvesting capability of the target AMP device, or it can be equal to the RSRQ offset related to the backscattering capability of the target AMP device, or it can be equal to the larger or smaller value of the two RSRQ offsets.

[0254] As an example, if the target AMP device supports energy harvesting and supports active transmission but does not support backscattering, the target RSRQ offset may be an RSRQ offset related to the energy harvesting capability of the target AMP device.

[0255] As another example, if the target AMP device supports both energy harvesting and backscattering, the target RSRQ offset may be equal to the sum of the two RSRQ offsets, or equal to one of the RSRQ offsets, or equal to the larger or smaller of the two.

[0256] Optionally, the RSRQ offset related to the energy harvesting capability of the target AMP device may be the difference between the minimum RSRQ required for the target AMP device to start the energy harvesting module or perform energy harvesting operations and the minimum RSRQ required by the network device side for traditional terminals.

[0257] For example, the minimum RSRQ required by the network device side for traditional terminals is z0dB, and the minimum RSRQ required for the target AMP device to start the energy harvesting module or perform energy harvesting operations is z1dB. Then the RSRQ offset related to the energy harvesting capability of the target AMP device is (z1-z0)dB.

[0258] Optionally, the RSRQ offset associated with the backscatter capability of the target AMP device may be a difference between a minimum RSRQ required for the target AMP device to start a backscatter module or perform a backscatter operation and a minimum RSRQ required by the network device side.

[0259] For another example, the minimum RSRQ required by the network device for traditional terminals is w0dB, and the minimum RSRQ required by the target AMP device to start the backscatter module or perform backscatter operations is w1dB. Then the RSRQ offset related to the backscatter capability of the target AMP device is (w1-w0)dB.

[0260] In some embodiments, the target cell selected by the target AMP device satisfies the following S criteria:

[0261] S rxlev >0, and S qual >0,

[0262] Among them, S rxlev =Q rxlevmeas -(Q rxlevmin +Q rxlevminoffset )-P compensation -Q offsettemp -P offsetAMP ,

[0263] S qual =Q qualmeas -(Q qualmin +Q qualminoffset )-Q offsettemp -Q offsetAMP ,

[0264] Among them, Q rxlevmeas and Q qualmeas Respectively represent the RSRP and RSRQ of the measured cell;

[0265] Q rxlevmin and Q qualminThey represent the minimum RSRP and minimum RSRQ required by the network equipment side for traditional terminals respectively;

[0266] Q rxlevminoffset , represents the RSRP offset, which is used to prevent the ping-pong effect between two PLMNs due to radio environment fluctuations;

[0267] Q qualminoffset , represents the offset of RSRQ, which is used to prevent the ping-pong effect between two PLMNs due to radio environment fluctuations;

[0268] P compensation Indicates the power compensation parameter. For example, when the maximum transmit power allowed by the network equipment side is greater than the maximum uplink transmit power determined by the UE's own capabilities, the power compensation caused by low UE power.

[0269] Q offsettemp Indicates a temporary offset, for example, only used in special scenarios, such as the "Chiba Problem" scenario;

[0270] P offsetAMP Indicates the target RSRP offset, i.e. Q rxlevmin +P offsetAMP is the target RSRP compensation parameter;

[0271] Q offsetAMP Indicates the target RSRQ offset, i.e. Q qualmin +Q offsetAMP is the target RSRQ compensation parameter.

[0272] In some embodiments, if the target AMP device supports energy harvesting and supports active transmission but not backscatter, the target RSRP offset may be an RSRP offset related to the energy harvesting capability of the target AMP device. For the above example, the target RSRP offset may be (x1-x0) dB.

[0273] In some embodiments, if the target AMP device supports both energy harvesting and backscattering, the target RSRP offset can be equal to the sum of the two RSRP offsets, or one of the RSRP offsets, or the larger or smaller of the two. For the above example, the target RSRP offset can be equal to (x1-x0)+(y1-y0)dB, or (x1-x0)dB, or (y1-y0)dB, or the larger or smaller of (y1-y0)dB and (x1-x0)dB.

[0274] In some embodiments, if the target AMP device supports energy harvesting and supports active transmission but does not support backscatter, the target RSRQ offset may be an RSRQ offset related to the energy harvesting capability of the target AMP device.

[0315] Method 3:

[0316] In some embodiments, the target RSRP compensation parameter is one of a plurality of RSRP compensation parameters, the plurality of RSRP compensation parameters are respectively associated with different AMP device capabilities, and the target RSRP compensation parameter is associated with the capability of the target AMP device.

[0317] In some embodiments, the multiple RSRP compensation parameters may be considered to be the minimum RSRP required by the network device for the AMP device of the multiple AMP device capabilities.

[0318] In some embodiments, the multiple RSRP compensation parameters are predefined or configured by the network device, for example, via a system message or RRC signaling.

[0319] In some embodiments, the multiple RSRP compensation parameters are determined according to the difference between the capabilities of the multiple AMP devices and the capabilities of a reference device, where the reference device may be a traditional terminal or a reference AMP device.

[0320] Therefore, the target AMP device can determine the target RSRP compensation parameter from the multiple RSRP compensation parameters according to its own capabilities, and further determine the Srxlev corresponding to the RSRP of the measured cell based on the target RSRP compensation parameter.

[0321] In some embodiments, the target RSRQ compensation parameter is one of a plurality of RSRQ compensation parameters, the plurality of RSRQ compensation parameters are respectively associated with different AMP device capabilities, and the target RSRQ compensation parameter is associated with the capability of the target AMP device.

[0324] In some embodiments, the multiple RSRQ compensation parameters are determined based on the difference between the capabilities of the multiple AMP devices and the capabilities of a reference device, which may be a traditional terminal or a reference AMP device.

[0325] Therefore, the target AMP device may determine the target RSRQ compensation parameter from the multiple RSRQ compensation parameters according to its own capability, and further determine the Squal corresponding to the RSRQ of the measured cell based on the target RSRQ compensation parameter.

[0326] Therefore, since the cell coverage supported by AMP devices of different capabilities is different, in this embodiment 1, when determining the Srxlev or Squal of the measured cell, the RSRP compensation parameter or RSRQ compensation parameter related to the capability of the AMP device is considered, which is conducive to ensuring that the AMP device selects a suitable cell, ensuring the normal operation of the energy harvesting module and / or backscattering module of the AMP device, and thus ensuring normal communication of the AMP device. For example, the AMP device with a larger minimum RSRP required to start the energy harvesting module and / or backscattering module has a smaller cell coverage supported. In this case, such AMP devices should try to avoid selecting cells with smaller Srxlev values ​​when selecting cells, otherwise the energy harvesting module and / or backscattering module of the AMP device will not work properly, and thus normal communication cannot be carried out.

[0327] Example 2: The target operation includes starting neighboring cell measurement

[0328] In this embodiment 2, the target parameter includes a parameter used to determine whether to start neighboring cell measurement.

[0329] For example, the target parameter includes a first target measurement result threshold, where the first target measurement result threshold is used by the target AMP device to determine whether to start neighboring cell measurement.

[0330] In some embodiments, the first target measurement result threshold includes a first target signal received power threshold (eg, RSRP threshold) and / or the first target signal received quality threshold (eg, RSRQ threshold).

[0331] In some specific embodiments, the first target signal receiving power threshold includes:

[0332] The signal receiving power threshold for the same frequency measurement (denoted as the first S IntraSearchP ), and / or, a signal receiving power threshold for non-co-frequency measurement (denoted as the first S nonIntraSearchP ).

[0333] In some specific embodiments, the first target signal quality threshold includes:

[0334] The signal reception quality threshold for the same-frequency measurement (denoted as the first S IntraSearchQ ), and / or, a signal reception quality threshold for non-co-frequency measurement (denoted as the first S nonIntraSearchQ ).

[0336] Below, the first S IntraSearchP As an example, the method for determining the parameters for determining whether to start neighboring area measurement is described. The first S IntraSearchP Can be replaced by the first S IntraSearchQ 、First S nonIntraSearchP 、First S nonIntraSearchQ Any parameter in .

[0337] In some embodiments of the present application, the first S IntraSearchP is predefined.

[0338] For example, you can predefine all AMP devices to use a unified S IntraSearchP Alternatively, AMP devices can be divided into multiple capabilities or types, with each capability or type corresponding to an S IntraSearchP , the first S IntraSearchP It can be the S corresponding to the capability of the target AMP device. IntraSearchP .

[0339] In other embodiments of the present application, the first S IntraSearchP It can be configured by the network device, for example, through system messages or RRC signaling.

[0340] For example, network devices can configure all AMP devices to use a unified S IntraSearchP Alternatively, AMP devices can be divided into multiple capabilities or types, and each capability or type is configured with a corresponding S IntraSearchP , the first S IntraSearchP It can be the S corresponding to the capability of the target AMP device. IntraSearchP .

[0341] In some other embodiments of the present application, the first S IntraSearchP It is determined by the target AMP device.

[0342] For example, the target AMP device can be configured based on the reference S IntraSearchP Determine the first S IntraSearchP , where the reference S IntraSearchP Can be S for reference device IntraSearchP , the reference device can be a traditional terminal or a reference AMP device.

[0343] Hereinafter, the first S is described in combination with the method 1 and the method 2. IntraSearchP How to determine.

[0344] Method 1: First S IntraSearchP According to reference S IntraSearchP Sure.

[0345] In some embodiments, reference S IntraSearchP It is the S corresponding to the traditional terminal or reference AMP device IntraSearchP .

[0346] In some embodiments, reference S IntraSearchP It is predefined or configured by the network device, for example, through system messages or RRC signaling.

[0347] In some embodiments, the target AMP device can IntraSearchP and the first RSRP offset to determine the first S IntraSearchP , the first RSRP offset is determined according to the capability difference between the target AMP device and the reference device.

[0348] For example, the reference device is a traditional terminal, and the reference S IntraSearchP It is an S for traditional terminals IntraSearchP If the minimum RSRP required by the network device for the traditional terminal is x0dBm, and the minimum RSRP required by the target AMP device to start the energy harvesting module or perform the energy harvesting operation is x1dBm, then the first RSRP offset can be (x1-x0)dB. IntraSearchP = Reference S IntraSearchP +(x1-x0)dB.

[0349] For another example, the reference device is a traditional terminal, and the reference S IntraSearchP It is an S for traditional terminals IntraSearchP If the minimum RSRP required by the network device for the traditional terminal is y0dBm, and the minimum RSRP required by the target AMP device to start the backscatter module or perform the backscatter operation is y1dBm, then the first RSRP offset can be (y1–y0)dB. IntraSearchP = Reference S IntraSearchP+(y1-y0)dB.

[0350] For example, the reference device is the reference AMP device, the reference S IntraSearchP is for the reference AMP device S IntraSearchP , if the minimum RSRP required by the reference AMP device to start the backscatter module or perform the backscatter operation is x2dBm, and the minimum RSRP required by the target AMP device to start the energy harvesting module or perform the energy harvesting operation is x1dBm, then the first RSRP offset can be (x1-x2)dB, then the first S IntraSearchP = Reference S IntraSearchP +(x1-x2)dB.

[0351] For another example, the reference device is a reference AMP device, and the reference S IntraSearchP is for the reference AMP device S IntraSearchP , if the minimum RSRP required by the reference AMP device to start the backscatter module or perform the backscatter operation is y2dBm, and the minimum RSRP required by the target AMP device to start the backscatter module or perform the backscatter operation is y1dBm, then the first RSRP offset may be (y1-y2)dB, then the first S IntraSearchP = Reference S IntraSearchP +(y1-y2))dB.

[0352] Mode 1-1: The first RSRP offset is determined by the target AMP device according to the capability difference between the target AMP device and the reference device. For the specific determination method, refer to the relevant description of the above embodiment.

[0353] Mode 1-2: The first RSRP offset is selected by the target AMP device from M RSRP offsets.

[0354] Among them, the M RSRP offsets correspond to M types of AMP device capabilities, and the M RSRP offsets are the S corresponding to the M types of AMP device capabilities. IntraSearchP S corresponding to the reference AMP device capability IntraSearchP The RSRP offset of the target AMP device is the RSRP offset corresponding to the capability of the target AMP device, and M is a positive integer.

[0355] In some embodiments, the M offsets are predefined or configured by a network device, for example, via a system message or RRC signaling.

[0356] Method 2: First S IntraSearchP In multiple S IntraSearchP selected.

[0357] In some embodiments, the multiple S IntraSearchP Corresponding to different AMP device capabilities, the first S IntraSearchP S is the capability of the target AMP device. IntraSearchP .

[0358] In some embodiments, the multiple S IntraSearchP It is predefined or configured by the network device, for example, through system messages or RRC signaling.

[0359] In some embodiments, the network device can configure the multiple S devices based on the capabilities of the multiple AMP devices. IntraSearchP .

[0360] Therefore, since the cell coverage supported by AMP devices with different capabilities is different, the areas for starting neighbor cell measurement are also different. In this embodiment 2, the target AMP device can select an appropriate measurement threshold based on the capabilities of the AMP device to determine whether to start neighbor cell measurement, which is conducive to ensuring that the AMP device starts neighbor cell measurement in an appropriate area. For example, for AMP devices with a larger minimum RSRP required by the energy collection model and / or backscatter module, the smaller the cell coverage it supports, such AMP devices can trigger neighbor cell measurement when Srxlev is large, avoiding the problem that the energy collection model and / or backscatter module of the AMP device cannot work due to the Srxlev of the currently resident cell being too small due to moving too fast, thereby affecting the normal communication of the AMP device.

[0361] Example 3: Target operation includes relaxing neighboring cell measurements

[0362] In this embodiment 3, the target parameters include parameters for relaxing neighboring cell measurement.

[0363] For example, the target parameter includes a target measurement result change threshold, and the target measurement result change threshold is used by the target AMP device to determine whether to relax the measurement of the neighboring cell.

[0364] In some specific embodiments, the target measurement result variation threshold includes a target signal received power variation threshold, such as a target RSRP variation threshold, denoted as target S SearchDeltaP .

[0365] In some embodiments, during an evaluation period (e.g., T SearchDeltaP ), when the change between the current Srxlev of the serving cell and the reference Srxlev of the serving cell does not exceed the target S SearchDeltaP When the target AMP device performs relaxed measurements on the neighboring cells.

[0366] In some embodiments, the target parameter may also include the evaluation time, such as TSearchDeltaP .

[0367] In some embodiments of the present application, the target S SearchDeltaP is predefined.

[0368] For example, you can predefine all AMP devices to use a unified S SearchDeltaP Alternatively, AMP devices can be divided into multiple capabilities or types, with each capability or type corresponding to an S SearchDeltaP , the target S SearchDeltaP It can be the S corresponding to the capability of the target AMP device. SearchDeltaP .

[0369] In other embodiments of the present application, the target S SearchDeltaP It can be configured by network devices.

[0370] For example, network devices can configure all AMP devices to use a unified S SearchDeltaP Alternatively, AMP devices can be divided into multiple capabilities or types, and each capability or type is configured with a corresponding S SearchDeltaP , the target S SearchDeltaP It can be the S corresponding to the capability of the target AMP device. SearchDeltaP .

[0371] In some other embodiments of the present application, the target S SearchDeltaP It is determined by the target AMP device.

[0372] For example, the target AMP device can be configured based on the reference S SearchDeltaP Determine the target S SearchDeltaP , where the reference S SearchDeltaP Can be S for reference device SearchDeltaP , the reference device can be a traditional terminal or a reference AMP device.

[0415] Mode 1-2: The third RSRP offset is selected by the target AMP device from M RSRP offsets.

[0416] In some embodiments, the M RSRP offsets correspond to M AMP device capabilities, and the M RSRP offsets are the S corresponding to the M AMP device capabilities. SearchThresholdP S corresponding to the reference AMP device capability SearchThresholdP The RSRP offset of the target AMP device is the RSRP offset corresponding to the capability of the target AMP device, and M is a positive integer.

[0417] In some embodiments, the M offsets are predefined or configured by a network device, for example, via a system message or RRC signaling.

[0418] Method 2: Second S SearchThresholdP In multiple S SearchThresholdP selected.

[0419] In some embodiments, the multiple S SearchThresholdP Corresponding to different AMP device capabilities, the second S SearchThresholdP S is the capability of the target AMP device. SearchThresholdP .

[0420] In some embodiments, the multiple S SearchThresholdP It is predefined or configured by the network device, for example, through system messages or RRC signaling.

[0421] In some embodiments, the network device can configure the multiple S devices based on the capabilities of the multiple AMP devices. SearchThresholdP .

[0422] Therefore, since the cell coverage supported by AMP devices with different capabilities is different, in this embodiment 4, the target AMP device can select an appropriate measurement result threshold based on the capabilities of the AMP device to determine whether it is located at the cell edge, thereby deciding whether to relax the measurement of the neighboring cell, or in other words, exit the relaxed neighboring cell measurement and perform normal neighboring cell measurement, which is conducive to ensuring that the AMP device can more quickly find a suitable neighboring cell to perform cell reselection. For example, for an AMP device with relatively poor cell coverage, a higher RSRP threshold is used, that is, when the RSRP measurement value of the cell is high, the relaxed neighboring cell measurement can be exited and the normal neighboring cell measurement can be entered, so as to more quickly find the neighboring cell to perform cell reselection.

[0423] It should be understood that the target AMP device may only perform a single operation in the above-mentioned embodiments 1 to 4, or may also perform multiple operations in the above-mentioned embodiments 1 to 4, and this application does not limit this.

[0424] For example, in cell selection, the target AMP device can select a suitable cell according to Example 1. Before cell reselection, the target AMP device can determine whether to start neighboring cell measurement according to Example 2, or determine whether to relax the measurement of neighboring cells according to Example 3. Alternatively, it can determine whether it is not at the cell edge according to Example 4, thereby determining whether to relax the measurement of neighboring cells, which is conducive to ensuring the mobility management performance of the target AMP device.

[0425] In summary, in the embodiments of the present application, the target AMP device can select appropriate parameters according to its own capabilities to perform operations related to cell selection or cell reselection, which is conducive to ensuring the mobility management performance of the target AMP device.

[0426] For example, in cell selection, the target AMP device can determine the target RSRP supplementary parameter or RSRQ supplementary parameter based on the difference between its own capabilities and the capabilities of the reference device. Furthermore, the Srxlev or Squal used for cell selection can be determined based on the target RSRP supplementary parameter or RSRQ supplementary parameter. When performing cell selection based on the Srxlev or Squal, it is beneficial to ensure that the AMP device selects a suitable cell, ensure the normal operation of the energy collection module and / or backscatter module of the AMP device, and thus ensure normal communication of the AMP device.

[0427] For another example, when determining whether to start neighboring cell measurement, the target AMP device can determine the target measurement result threshold based on the difference between its own capabilities and the capabilities of the reference device. Furthermore, it can determine whether to start neighboring cell measurement based on the target measurement result threshold, which is conducive to ensuring that the AMP device starts neighboring cell measurement in a suitable area, ensuring the normal operation of the energy collection module and / or backscatter module of the AMP device, and thus ensuring normal communication of the AMP device.

[0428] For another example, when determining whether it is not located at the edge of a cell, the target AMP device can determine the target measurement result threshold based on the difference between its own capabilities and the capabilities of the reference device. Furthermore, it can determine whether it is not located at the edge of the cell based on the target measurement result threshold, which is conducive to ensuring that the AMP device exits the relaxed neighboring area measurement and performs normal neighboring area measurement in a suitable area, and is conducive to ensuring that the AMP device finds a suitable neighboring area more quickly to perform cell reselection, and ensures the normal operation of the energy collection module and / or backscatter module of the AMP device, thereby ensuring normal communication of the AMP device.

[0465] For example, the minimum RSRP required for the reference AMP device to start the backscatter module or perform the backscatter operation is y2dBm, and the minimum RSRP required for the target AMP device to start the backscatter module or perform the backscatter operation is y1dBm. Then the RSRP offset related to the backscatter capability of the target AMP device is (y1-y2)dB.

[0466] Optionally, the RSRQ offset associated with the energy harvesting capability of the target AMP device may be the difference between the minimum RSRQ required for the target AMP device to start the energy harvesting module or perform energy harvesting operations and the minimum RSRP required for the reference AMP device to start the backscattering module or perform backscattering operations.

[0467] For example, the minimum RSRQ required for the reference AMP device to start the energy harvesting module or perform energy harvesting operations is z2dB, and the minimum RSRQ required for the target AMP device to start the energy harvesting module or perform energy harvesting operations is z1dB. Then the RSRQ offset related to the energy harvesting capability of the target AMP device is (z1-z2)dB.

[0481] Accordingly, in this embodiment 3, the target offset is relative to S SearchDeltaP RSRP offset (denoted as the second RSRP offset).

[0482] In some embodiments, the second RSRP offset is determined according to a capability difference between the target AMP device and the reference device.

[0483] For example, the reference device is a traditional terminal, and the reference S SearchDeltaP It is an S for traditional terminals SearchDeltaP If the minimum RSRP required by the network device for the traditional terminal is x0dBm, and the minimum RSRP required by the target AMP device to start the energy collection module or perform the energy collection operation is x1dBm, then the second RSRP offset can be (x1-x0)dB.

The method for determining the third RSRP offset is similar. For the sake of brevity, it will not be repeated here.

[0490] In some embodiments, the third RSRP offset is determined according to a capability difference between the target AMP device and the reference device.

[0491] For example, the reference device is a traditional terminal, and the reference S SearchThresholdP It is the S corresponding to the traditional terminal SearchThresholdP If the minimum RSRP required by the network device for the traditional terminal is x0dBm, and the minimum RSRP required by the target AMP device to start the energy collection module or perform the energy collection operation is x1dBm, then the third RSRP offset can be (x1-x0)dB.
