[0049] To better understand the technical solution of this application, the following contents are first introduced:

[0050] 1. Ambient IoT

[0051] Ambient IoT is a new 3GPP IoT technology. Ambient IoT terminals have ultra-low complexity and ultra-low power consumption.

[0052] Ambient IoT, also known as the ambient power-enabled Internet of Things (Ambient power-enabled IoT), is an IoT service in which IoT devices are powered by energy harvesting. IoT devices lack batteries or have limited energy storage capabilities (for example, using a capacitor). Energy harvesting can be done from radio waves, light, motion, heat, or other suitable energy sources.

[0053] Low-power IoT devices are IoT devices with low overall power consumption, including low-power signal reception and low-power signal transmission. Due to their low overall power consumption, communication energy can come from the environment, such as wind energy, kinetic energy, thermal energy, and radio frequency (RF) signals. They are also called ambient IoT, passive IoT devices, and transponder devices.

[0054] Ambient IoT terminals can be classified based on energy source, energy storage capability, passive or active emission, etc. There are three types of devices:

[0055] (1) Device Type A: A passive device with no independent signal generation or amplification, i.e., backscatter transmission.

[0056] (2) Device Type B: A semi-passive device, also belonging to the passive device category. It has energy storage but no independent signal generation, i.e., backscatter transmission. The use of stored energy may include amplification of the reflected signal.

[0057] (3) Device Type C: Active device, with energy storage and independent signal generation, that is, active RF components for transmission.

[0058] 2. Ambient IoT Communication Application Scenarios

[0059] Figure 1b : The network sends a carrier wave (CW) and signaling and receives the reflected signal from the tag.

[0060] Figure 1c : The terminal sends CW and signaling and receives the tag's reflected signal.

[0061] Figure 1d : The network sends CW and signaling to the tag; the terminal receives the backscatter information sent by the tag.

[0062] Figure 1e : The terminal sends CW and signaling to the tag; the network receives the backscattered information from the tag.

[0063] It should be noted that the types of network side devices, such as base stations, include but are not limited to: base station types include: IAB node (IAB station), repeater (repeater) such as: network controlled repeater, Pole station (pole station).

[0064] 3. A-IoT data / service types

[0065] A-IoT studies the following data / business types:

[0066] DO:Device-originated

[0067] DT:Device-terminated

[0068] DO-A: Device-originated–autonomous

[0069] DO-DTT:Device-originated–device-terminated triggered

[0070] DO and DT data represent data flows originating from A-IoT devices (similar to RFID tags) or transmitted to A-IoT devices. Data flows originating from A-IoT devices, i.e., DO data, can be further categorized as follows:

[0071] (1) DO-A (Device-originated Autonomous), which means the device initiates data transmission autonomously

[0072] For example: connecting a large number of various sensors that collect and, when necessary, actively report information about the environment, equipment, and organisms.

[0073] (2) DO-DTT (Device-originated–device-terminated triggered), where the device initiates data transmission after being triggered by the network

[0074] For example, asset identification, status reporting, and tracking are all DL-triggered reports, where the Reader collects data from the tag by triggering the inventory process. Since the data is generated / initiated in the IoT device, this service should be considered a command sent by the Reader to trigger the tag to initiate a DO service.

[0075] Cell reselection measurement start criteria

[0076] Intra-frequency measurement:

[0077] If the serving cell satisfies Srxlev>S IntraSearchP and Squal>S IntraSearchQ , the UE may not perform intra-frequency measurement, otherwise, the UE should perform intra-frequency measurement.

[0078] Inter-frequencies and inter-RAT frequencies measurements:

[0079] For higher priority NR inter-frequency or inter-RAT frequency, the UE should always measure;

[0080] If the serving cell satisfies Srxlev>SnonIntraSearchP and Squal>SnonIntraSearchQ, the UE may not perform NR inter-frequency or lower priority inter-RAT frequency measurement. Otherwise, the UE shall perform NR inter-frequency or lower priority inter-RAT frequency measurement.

[0081] Cell selection and reselection criteria

[0082] 1.Inter-frequency and inter-RAT Cell Reselection criteria

[0083] Higher priority NR frequency or inter-RAT frequency than the serving frequency:

[0084] If the system information broadcasts threshServingLowQ and more than 1 second has passed since the terminal camped on the current serving cell, the terminal should reselect to a cell on an NR frequency or inter-RAT frequency with a higher priority than the current serving frequency if the following conditions are met:

[0085] (1) In a time interval Treselection RAT A cell with a higher priority NR or EUTRAN RAT / frequency satisfies Squal>Thresh X,HighQ

[0086] Otherwise, if the following conditions are met, the terminal should reselect to a cell on an NR frequency or inter-RAT frequency with a higher priority than the current serving frequency:

[0087] (2) In a time interval Treselection RAT A cell with a higher priority RAT / frequency satisfies Srxlev>Thresh X,HighP

[0088] (3) More than 1 second has passed since the terminal resided in the current serving cell;

[0089] Lower priority NR frequency or inter-RAT frequency than the serving frequency:

[0090] If the system information broadcasts threshServingLowQ and more than 1 second has passed since the terminal camped on the current serving cell, the terminal shall reselect to a cell on an NR frequency or inter-RAT frequency with a lower priority than the current serving frequency if the following conditions are met:

[0091] (1) In a time interval Treselection RAT Within, the serving cell meets Squal <Thresh Serving,LowQ And the lower priority NR or E-UTRAN RAT / frequency satisfies Squal>Thresh X,LowQ

[0092] Otherwise, if the following conditions are met, the terminal should reselect to a cell on an NR frequency or inter-RAT frequency with a lower priority than the current serving frequency:

[0093] (2) In a time interval Treselection RATThe serving cell satisfies Srxlev <Thresh Serving,LowP And a cell with a lower priority RAT / frequency satisfies Srxlev>Thresh X,LowP

[0094] (3) It has been more than 1 second since the terminal has been stationed in the current serving cell

[0095] If more than one cell meets the above conditions, the terminal shall select a cell as follows:

[0096] (1) If the highest priority frequency is an NR frequency, reselect to the highest ranked cell that meets the R criteria on that frequency;

[0097] (2) If the highest priority frequency is a frequency of another RAT, reselect to the strongest cell on that frequency that meets the reselection criteria of that RAT;

[0098] Explanation of the above parameters:

[0099] Srxlev=Q rxlevmeas –(Q rxlevmin +Q rxlevminoffset )–P compensation -Qoffset temp

[0100] Squal=Q qualmeas –(Q qualmin +Q qualminoffset )-Qoffset temp

[0101] Srxlev: cell selection receiving level value

[0102] Q rxlevmeas : Measured cell reception level / signal strength (RSPR)

[0103] Q rxlevmin , Q rxlevminoffset 、P compensation 、Qoffset temp All configured on the network side

[0104] Squal: cell selection quality value

[0105] Q qualmeas : Measured cell quality value (RSRQ)

[0106] Q qualmin , Q qualminoffset 、Qoffset temp All configured on the network side

[0107] 2. Intra-frequency and equal priority inter-frequency Cell Reselection criteria

[0108] The cell ranking criteria are defined as follows, where Rs is used for the serving cell and Rn is used for the neighboring cell.

[0109] R s =Q meas,s +Q hyst -Qoffset temp

[0110] R n =Q meas,n -Q offset -Qoffset temp

[0111] The terminal sorts the cells that meet the cell selection criterion S.

[0112] If rangeToBestCell is not configured, the terminal will perform cell reselection on the cell with the highest ranking.

[0113] If rangeToBestCell is configured, the terminal reselects to a cell whose beam count is above the threshold (absThreshSS - BlocksConsolidation), whose beam count differs from the threshold by a greater margin than the beam counts of other cells, and whose R value is within the rangeToBestCell range of the highest-ranked cell. The R value is calculated based on the same-frequency or equal-priority different-frequency cell reselection criteria.

[0114] The cell reselection or cell selection method provided in the embodiments of the present application is described in detail below with reference to some embodiments and their application scenarios in conjunction with the accompanying drawings.

[0115] See also Figure 2a The embodiment of the present application provides a cell reselection or cell selection method, the execution subject of the method is a terminal, and the method includes:

[0116] Step 201: The terminal obtains target information;

[0117] Step 202: The terminal performs cell reselection or cell selection based on the target information;

[0118] The target information is related to the AIoT device, and the target information includes at least one of cell reselection related information and cell selection related information;

[0119] The terminal may obtain the target information by receiving system information sent by the network, or the terminal may obtain the target information by reading information of the AIoT device, or a combination of the two.

[0120] The cell reselection related information includes at least one of the following:

[0121] (1) First information, the first information is used to start cell reselection measurement; this allows the terminal to determine whether to perform neighboring cell measurement based on the detected AIoT device;

[0122] (2) second information, which includes information related to the cell reselection rule; this allows the terminal to determine whether to reselect to a cell based on the AIoT device corresponding to the cell and the detected AIoT device;

[0123] (3) at least one third information and at least one fourth information, wherein the third information includes information related to cell reselection and the fourth information includes information related to the AIoT device. This allows the terminal to determine which set of cell reselection parameters to apply based on the detection of the AIoT device;

[0124] In an embodiment of the present application, cell reselection or cell selection is performed based on information related to the AIoT device, thereby realizing AIoT device-assisted cell selection and reselection.

[0125] In one possible implementation, the terminal may obtain target information in at least one of the following ways: 1) obtaining target information through a network-side device, 2) obtaining target information through a server (e.g., a third-party server), or 3) obtaining target information by reading information from an AIoT device. Obtaining target information through a network-side device includes obtaining target information in at least one of the following ways: 1) obtaining target information by receiving system information sent by a network-side device; or 2) obtaining target information by receiving dedicated signaling (e.g., an RRCRelease message) sent by a network-side device.

[0126] In one possible implementation, the first information includes at least one of the following:

[0127] (1) at least one fifth information, each fifth information including: at least one AIoT device identification information for indicating an AIoT device, or at least one grid information for indicating a grid;

[0128] (2) at least one sixth information, each sixth information being used to indicate at least one threshold value, the threshold value including a measurement-related threshold value for indicating a measurement of an AIoT device signal;

[0129] There is a first correspondence between the fifth information and the sixth information, and the first correspondence satisfies any one of the following:

[0130] (1) One sixth information corresponds to all fifth information; that is, all AioT devices indicated in the fifth information share the same threshold;

[0131] (2) a sixth information corresponding to a portion of the fifth information; that is, the AioT devices indicated in the portion of the fifth information share a common threshold;

[0132] (3) The sixth information corresponds to the fifth information one-to-one. That is, the AioT devices indicated in the fifth information share one threshold value, or multiple AioT devices indicated in the fifth information share one threshold value, or each pair of AioT devices indicated in the fifth information uses one threshold value.

[0133] In one possible implementation, the fifth information satisfies at least one of the following:

[0134] (1) All frequencies corresponding to all Radio Access Technologies (RATs);

[0135] (2) All frequencies corresponding to at least one RAT;

[0136] The fifth information may be common to all RATs (e.g., NR, E-URAN), or may be per RAT or per RAT group.

[0137] (3) corresponds to a frequency;

[0138] (4) corresponds to a frequency group.

[0139] The fifth information can be shared by all frequencies, that is, corresponding to all frequencies; it can also be per frequency, that is, each fifth information corresponds to a frequency; or per frequency group, that is, each fifth information corresponds to a group of frequencies. For example, the frequency grouping method can be: frequencies with higher priority than the service frequency are grouped together, the service frequencies are grouped together, and frequencies with equal priority to the service frequencies or frequencies with lower priority than the service frequencies are grouped together.

[0140] Exemplarily, if the fifth information corresponds to a frequency point, for heterogeneous frequencies, a list is introduced, each element in the list is a fifth information, the length of the list is equal to the length of interFreqCarrierFreqList in SIB4, and each element in the list corresponds one-to-one to each element of interFreqCarrierFreqList, indicating that the fifth information corresponding to each frequency point in interFreqCarrierFreqList, the list can be carried by SIB4 or by a new SIB; for heterogeneous system frequencies, a list is introduced, each element of which is a fifth information, the length of the list is equal to the length of carrierFreqListEUTRA in SIB5, and each element in the list corresponds one-to-one to each element of interFreqCarrierFreqList, indicating that the fifth information corresponding to each frequency point in interFreqCarrierFreqList, the list can be carried by SIB5 or by a new SIB; for homogeneous frequencies, a new IE is introduced to indicate the fifth information corresponding to the service frequency point, which can be carried by SIB3 or an information IE is introduced to carry

[0141] For another example, if the fifth information corresponds to a frequency / frequency group, a list is introduced, and each element in the list is a piece of fifth information and its corresponding frequency / frequency group.

[0142] Optionally, the terminal may obtain the first information through system information, such as system information (SIB2, SIB3, SIB4, SIB5) providing cell reselection related parameters, or introduce new system information to provide the first information.

[0143] In a possible implementation, the terminal performs cell reselection according to the target information, including at least one of the following:

[0144] (1) When the terminal detects the AIoT device indicated by the fifth information, the terminal performs neighbor cell measurement;

[0145] (2) When the terminal is in the grid indicated by the fifth information, the terminal performs neighbor cell measurement;

[0146] (3) If the terminal does not detect the AIoT device indicated by the fifth information, the terminal determines not to perform neighbor cell measurement;

[0147] (4) When the terminal is not in the grid indicated by the fifth information, the terminal determines not to perform neighbor cell measurement.

[0148] If the terminal detects the AIoT device indicated by the fifth information, or the terminal is in the grid indicated by the fifth information, the terminal performs neighboring cell measurement. If the terminal cannot detect the AIoT device indicated by the fifth information, or the terminal is not in the grid indicated by the fifth information, the terminal determines not to perform neighboring cell measurement. The neighboring cell measurement includes at least one of a frequency measurement with a higher priority than the serving frequency, a same-frequency measurement, and a frequency measurement with a priority equal to the serving frequency or a frequency measurement with a lower priority than the serving frequency.

[0149] It can be understood that the relationship between this condition and the neighbor cell measurement starting condition of the existing mechanism (the starting condition based on the RRM measurement result) is an "and" or "or" relationship.

[0150] It should be noted that the terminal being in the grid indicated by the fifth information means that the terminal is in any grid indicated by the fifth information; the terminal not being in the grid indicated by the fifth information means that the terminal is not in all grids indicated by the fifth information;

[0151] Optionally, the terminal determines whether it is in a grid based on the terminal's location information:

[0152] One implementation method: If the grid is represented by a reference position plus a distance threshold (which can be understood as modeling the grid as a circle), if the distance between the terminal position and the reference position is less than or equal to the distance threshold, the terminal is in the grid; otherwise (if the distance between the terminal position and the reference position is greater than or equal to the distance threshold), the terminal is not in the grid.

[0153] In another implementation, if the grid is modeled as a polygon, if the terminal is within the polygon, it means that the terminal is in the grid; if the terminal is not within the polygon, it means that the terminal is not in the grid.

[0154] In a possible implementation, when the terminal detects the AIoT device indicated by the fifth information, the terminal performs neighbor cell measurement, including at least one of the following:

[0155] (1.1) When the terminal detects the AIoT device indicated by the fifth information and the fifth information corresponds to all frequencies of all RATs, the terminal performs measurement of the frequencies of all RATs;

[0156] (1.2) When the terminal detects the AIoT device indicated by the fifth information, and the fifth information corresponds to all frequencies of at least one RAT, the terminal performs measurement of the frequency of at least one RAT;

[0157] (1.3) When the terminal detects the AIoT device indicated by the fifth information, the fifth information corresponds to a frequency, and the terminal performs measurement of the frequency corresponding to the fifth information;

[0158] (1.4) When the terminal detects the AIoT device indicated by the fifth information and the fifth information corresponds to a frequency group, the terminal performs measurement of the frequency group corresponding to the fifth information;

[0159] When the terminal is in the grid indicated by the fifth information, the terminal performs neighbor cell measurement, including:

[0160] (2.1) When the terminal is in the grid indicated by the fifth information and the fifth information corresponds to all frequencies of all RATs, the terminal performs measurement of the frequencies of all RATs;

[0161] (2.2) when the terminal is in the grid indicated by the fifth information and the fifth information corresponds to all frequencies of at least one RAT, the terminal performs measurement of the frequency of at least one RAT;

[0163] (2.4) When the terminal is in the grid indicated by the fifth information and the fifth information corresponds to a frequency group, the terminal performs measurement of the frequency group corresponding to the fifth information.

[0164] In a possible implementation, when the terminal does not detect the AIoT device indicated by the fifth information, the terminal determines not to perform neighbor cell measurement, including at least one of the following:

[0165] (3.1) When the terminal does not detect the AIoT device indicated by the fifth information, and the fifth information corresponds to all frequencies of all RATs, the terminal determines not to perform measurement of the frequencies of all RATs;

[0166] (3.2) If the terminal does not detect the AIoT device indicated by the fifth information, and the fifth information corresponds to all frequencies of at least one RAT, the terminal determines not to perform measurement of the frequency of at least one RAT;

[0167] (3.3) When the terminal does not detect the AIoT device indicated by the fifth information, the fifth information corresponds to a frequency, and the terminal determines not to perform measurement of the frequency corresponding to the fifth information;

[0175] For example, the network provides the second information corresponding to each frequency and the fifth information corresponding to f1 (AIoT ID 1, AIoTID 2, AIoT ID 3). If the terminal detects the AIoT device indicated by the fifth information, or the terminal is in the grid indicated by the fifth information, the terminal performs measurement on f1 (regardless of the measurement result of the serving cell, regardless of the frequency priority of f1). If the terminal cannot detect the AIoT device indicated by the fifth information, or the terminal is not in the grid indicated by the fifth information, the terminal determines not to perform measurement on f1 (regardless of the measurement result of the serving cell, regardless of the frequency priority of f1).

[0176] In one possible implementation, the terminal detects the AIoT device indicated by the fifth information, including at least one of the following:

For example, the ratio of the number of AIoT devices indicated by the detected second information to the total number of AIoT devices indicated by the second information is greater than or equal to 60%. The threshold can be agreed upon by the protocol or indicated by the network side.

[0183] (2) The terminal measures that the measurement value of the signal of at least some of the AIoT devices indicated by the fifth information is greater than or equal to a first threshold, and the first threshold is predefined by the protocol, configured on the network side, preconfigured, or indicated by the sixth information.

The first cell is the cell that satisfies the first condition and in which the terminal detects the largest number of AIoT devices indicated by the corresponding seventh information. The first condition includes that the R value is greater than or equal to a threshold. The threshold can be agreed upon by the protocol or configured on the network side. For example, the threshold can be directly indicated, or indirectly indicated, such as indicating a difference. The maximum R value of the cell detected by the terminal minus the difference is the threshold.

[0201] (2) the terminal reselects to a second cell, the second cell belongs to a second cell set that satisfies a second condition, and the second cell has the highest R value ranking in the second cell set, where the second condition includes that the terminal detects that the number of AIoT devices indicated by the seventh information corresponding to the cell is greater than or equal to a third threshold;
