Optionally, the wireless communication system may include at least two network side devices and the coverage range of each network side device may include other numbers of terminals and A-IoT devices. This embodiment of the present application is not limited to this.

[0059] To facilitate a better understanding of the embodiments of the present application, the Ambient Internet of Things (A-IoT) is described.

[0060] A-IoT devices have ultra-low complexity and ultra-low power consumption.

[0061] A-IoT, also known as ambient power-enabled Internet of Things (Ambient Power-Enabled IoT), is a type of Internet of Things (IoT) service. A-IoT devices are powered by energy harvesting. A-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.

[0062] A-IoT devices can also be referred to as A-IoT terminals, passive IoT devices, ambient power (AMP) devices, zero-power devices, low-power IoT devices, IoT devices, transponders, tags, and radio frequency identification (RFID) tags. These devices have low overall power consumption, including low-power signal reception and low-power signal transmission. Due to this low overall power consumption, communication energy can be derived from the environment, such as wind energy, kinetic energy, thermal energy, and radio frequency (RF) signals.

[0063] A-IoT devices can be classified based on energy source, energy storage capability, and passive or active emission. Specifically, they can include the following three types of devices:

[0064] Device Type A: A passive device with no independent signal generation or amplification, i.e., backscatter transmission.

[0065] Device Type B: A semi-passive device, also within the passive device category, with energy storage but no independent signal generation, i.e., backscatter transmission. The use of stored energy may include amplification of reflected signals.

[0066] Device Type C: Active device, with energy storage and independent signal generation, that is, active RF components for transmission.

[0067] To facilitate a better understanding of the embodiments of the present application, backscatter communication (BSC) is described.

[0068] Backscatter communication refers to the use of radio frequency signals from other devices or the environment to modulate the signal and transmit its own information. Backscatter technology, a passive or low-energy technology, is characterized by its ability to transmit its own signal by modifying the characteristics of the received ambient radio frequency signal, such as its phase or amplitude, achieving extremely low or zero power consumption.

[0069] For example, a backscatter transmission method based on binary on-off keying (OOK) can be shown in FIG2 . A simple implementation method is that when the tag needs to send '1', the tag reflects the incident carrier signal, and when the tag needs to send '0', it does not reflect.

[0070] Exemplarily, backscatter communication can be shown in Figure 3. The A-IoT device receives the wireless signal sent by the reading and writing device, modulates the wireless signal, loads the information to be sent, and radiates the modulated signal from the antenna. This information transmission process is called backscatter communication.

[0071] Backscatter communication devices (such as A-IoT) control the circuit's reflection coefficient Γ by adjusting its internal impedance, thereby changing the amplitude, frequency, phase, etc. of the incident signal to achieve signal modulation. The signal reflection coefficient can be expressed as:

[0072] Where Z0 is the antenna characteristic impedance and Z1 is the load impedance. Assume that the incident signal is S in (t), the output signal is Therefore, corresponding amplitude modulation, frequency modulation or phase modulation can be achieved by reasonably controlling the reflection coefficient.

[0073] Backscatter communication devices (such as A-IoT devices) typically use low-power reception, typically using low-power RF, IF, or baseband envelope detection. The waveform of the transmitted signal typically uses simple modulation methods such as on-off keying (OOK), amplitude shift keying (ASK), and frequency shift keying (FSK).

[0074] The device that communicates with such low-power devices (such as A-IoT devices) is called a read-write device or a first network element. For example, it can be a terminal or a relay device or a repeater, or a base station or TRP, or a device with read-write functions, such as a reader / writer. The specific details are not limited here.

[0075] To facilitate a better understanding of the embodiments of the present application, the A-IoT data / service types are explained.

[0076] Device-originating (DO) and device-terminating (DT) data indicate that the data flow originates from or is transmitted to an A-IoT device (similar to an RFID tag). Data flows originating from A-IoT devices, or DO data, can be further categorized as device-originating-autonomous (DO-A) and device-originating–device-terminated triggered (DO-DTT).

[0077] DO-A, which means devices autonomously initiate data transmission, such as connecting a large number of various sensors that collect and actively report information about the environment, equipment, and organisms when necessary.

[0078] DO-DTT refers to devices initiating data transmission after being triggered by the network. For example, asset identification, status reporting, and tracking are all downlink-triggered reports. Readers collect data from tags by triggering inventory processes. Because the data is generated / initiated in IoT devices, this service should be considered a DO service initiated by a tag, triggered by a command sent by the reader.

[0079] To facilitate a better understanding of the embodiments of the present application, the information transmission between the reader and the tag in the RFID is described.

[0080] RFID is a traditional backscatter communication system whose primary design goal is to identify and read data from BSC devices (i.e., tags) within the reader's coverage area. Because RFID was initially used for automated inventory counting of large quantities of goods, the process of identifying and reading tags is also known as inventorying. For example, after the reader sends a query command (Query), the tag responds (Reply). For example, if the Reply is RN16, the tag generates a 16-bit random number and sends it to the reader. The reader then sends this sequence to the tag via an ACK command. After the tag successfully verifies the RN16 in the ACK, it sends the subsequent data (such as PC / XPC, EPC, etc.) to the reader.

[0081] For example, the command (Command) of the reader (Reader) operation may be as shown in Table 1 below, and the status of the tag (Tag) may be as shown in Table 2 below.

[0083] Table 2

[0084] To facilitate understanding of the technical solutions of the embodiments of the present application, the technical solutions of the present application are described in detail below through specific embodiments. The above related technologies can be combined arbitrarily with the technical solutions of the embodiments of the present application as optional solutions, and all of them fall within the scope of protection of the embodiments of the present application. The embodiments of the present application include at least part of the following contents.

[0085] FIG4 is a schematic flow chart of a conditional switching method 200 according to an embodiment of the present application. As shown in FIG4 , the conditional switching method 200 may include at least part of the following contents:

[0086] S210: The terminal obtains A-IoT information; wherein the A-IoT information includes at least one of the following: identification information of at least one A-IoT device, location information of at least one A-IoT device, grid information of at least one A-IoT device, and reflected signal strength information of at least one A-IoT device;

[0087] S220, the terminal evaluates a conditional handover execution condition of the first candidate cell according to the A-IoT information;

[0088] S230: When a conditional switching execution condition corresponding to the first candidate cell is satisfied, the terminal switches to the first candidate cell.

[0089] It should be understood that FIG4 shows the steps or operations of the conditional switching method 200, but these steps or operations are merely examples, and the present application may also perform other operations or variations of the operations in FIG4.

[0090] In an embodiment of the present application, the terminal obtains A-IoT information; and the terminal evaluates the conditional switching execution condition of at least one candidate cell based on the A-IoT information, that is, the terminal can evaluate the conditional switching execution condition based on the auxiliary evaluation of the A-IoT device, and can achieve more accurate conditional switching based on the A-IoT information, reduce the power consumption of the conditional switching, and improve the network energy-saving performance.

[0091] In the embodiment of the present application, the grid can also be understood as a network zone.

[0092] In some embodiments, cells in the network may be divided into at least two grids. For example, a schematic diagram of dividing cells in the network into grids may be shown in FIG5 .

[0093] In some embodiments, the network side may support at least one mesh segmentation scheme or granularity, for example, mesh segmentation according to the granularity of A-IoT devices.

[0094] For example, different cells in the network may use a unified grid partitioning scheme or granularity.

[0095] For example, an A-IoT device can be deployed in at least two cells at the same time.

[0096] For example, an operator can deploy A-IoT devices in the network, and the cells in the network are divided into multiple grids. The terminal or A-IoT device can be in a specific grid, that is, the location information of the terminal or A-IoT device can be represented by the grid information.

[0097] In some embodiments, the A-IoT device may also be an A-IoT terminal, a passive Internet of Things (Passive-IoT) device, an ambient energy (AMP) device, a zero-power device, a low-power IoT device, an IoT device, a response device, a tag, an RFID tag, etc.

[0098] It should be noted that in order to prevent the terminal from being unable to receive handover command-related messages from the source base station after the channel condition of the source cell deteriorates, thereby causing handover failure, conditional handover (CHO) is introduced.

[0099] The conditional switching described in the embodiments of the present application includes but is not limited to at least one of the following:

[0100] Conditional switching during single connection;

[0101] Conditional switching of the primary cell (PCell) during dual connectivity;

[0102] Conditional PSCell Addition or Change (CPAC);

[0103] Conditional switching of the secondary cell group (SCG);

[0104] Conditional layer 1 triggered mobility process (L1 triggered mobility);

[0105] Conditional layer 2 triggered mobility process (L2 triggered mobility);

[0106] The movement process triggered by the underlying condition.

[0107] Optionally, the conditional primary and secondary cell addition or change (CPAC) includes at least one of the following:

[0108] Conditional PSCell Addition (CPA);

[0109] Change of conditions of primary and secondary cells within the secondary node (Intra-SN CPC);

[0110] MN initiated Inter-SN CPC;

[0111] SN initiated Inter-SN CPC;

[0112] Subsequent CPAC.

[0113] Exemplarily, conditional primary and secondary cell addition involves the UE evaluating execution conditions and executing the addition of primary and secondary cells only after the execution conditions are met. The Conditional Primary and Secondary Cell Change (CPA) configuration includes the configuration of CPA candidate cells and execution conditions. The execution conditions may include one or two trigger conditions.

[0114] Exemplarily, a conditional primary / secondary cell change involves the UE evaluating execution conditions and executing the change only after the execution conditions are met. Upon receiving the CPC configuration, the UE begins evaluating the execution conditions. The UE stops evaluating the execution conditions after the primary / secondary cell change is triggered. The CPC configuration includes the configuration of CPC candidate cells and the execution conditions. The execution conditions may include one or two triggering conditions. Upon successful completion of the primary / secondary cell change procedure, the UE releases all stored CPC configurations.

[0115] For example, CPC includes various scenarios, such as:

[0116] Change of conditions of primary and secondary cells within the secondary node (Intra-SN CPC);

[0117] MN initiated Inter-SN CPC;

[0118] SN initiated Inter-SN CPC (SN initiated Inter-SN CPC).

[0119] In some embodiments, the terminal may obtain A-IoT information through an A-IoT device.

[0120] In some embodiments, the above S210 may specifically include:

[0121] The terminal obtains A-IoT information through at least one of the following:

[0122] Inventory, detection, and measurement of A-IoT devices.

[0123] It should be noted that, from the perspective of the terminal (UE), the UE has A-IoT capability (capable), which is called Ambient IoT capable UE, that is, the UE has 3GPP communication capability and Ambient IoT capability. Ambient IoT capable UE can take inventory of Ambient IoT devices. For example, the UE can take inventory of Ambient IoT devices under the control of the network, for example, the network configures wireless resources for the UE so that the UE performs Ambient IoT related operations on the wireless resources. In an embodiment of the present application, the terminal (UE) can take inventory or detect or measure these A-IoT devices. These operations of taking inventory or detecting or measuring A-IoT devices can be regarded as a background task in the 3GPP communication process.

[0124] Exemplarily, the terminal (UE) may inventory, detect, or measure these A-IoT devices to obtain conditional handover information, that is, evaluate the conditional handover execution condition of the first candidate cell with the assistance of the A-IoT devices.

[0125] In some embodiments, before the terminal evaluates the conditional handover execution condition of the first candidate cell according to the A-IoT information, the conditional handover method 200 further includes:

[0126] The terminal receives first configuration information from the network side device;

[0127] The first configuration information is used to configure or indicate a conditional handover execution condition of at least one candidate cell, and the at least one candidate cell includes the first candidate cell.

[0128] In this embodiment, the conditional switching execution condition of at least one candidate cell can be determined based on the first configuration information, thereby evaluating the conditional switching execution condition of at least one candidate cell based on the A-IoT information. That is, the terminal can evaluate the conditional switching execution condition based on the auxiliary evaluation of the A-IoT device, and can achieve more accurate conditional switching based on the A-IoT information, reduce the power consumption of the conditional switching, and improve the network energy saving performance.

[0129] Exemplarily, the first configuration information may be carried by a radio resource control (RRC) reconfiguration message.

[0130] It should be understood that the first configuration information may also be carried through other messages or signaling, which is not limited in this embodiment.

[0131] In some embodiments, the conditional handover execution condition includes an A-IoT execution condition corresponding to the first candidate cell;

[0132] The A-IoT execution condition corresponding to the first candidate cell satisfies at least one of the following:

[0133] The terminal is in the target grid;

[0134] The target A-IoT device is detected;

[0135] The target A-IoT measurement event is met.

[0136] Exemplarily, when the terminal is in the target grid and the A-IoT execution condition corresponding to the first candidate cell is met, the terminal can switch to the first candidate cell.

[0137] For example, when the terminal detects the target A-IoT device and the A-IoT execution condition corresponding to the first candidate cell is met, the terminal can switch to the first candidate cell.

[0138] Exemplarily, when the target A-IoT measurement event is satisfied, the A-IoT execution condition corresponding to the first candidate cell is satisfied. In this case, the terminal can switch to the first candidate cell.

[0139] In some implementations, a terminal can determine its grid location based on the grid location of the A-IoT device. For example, if the terminal detects that the closest A-IoT device is located in grid A, the terminal can determine that it is in grid A. For another example, if the terminal detects that the A-IoT device with the highest reflected signal strength is located in grid A, the terminal can determine that it is in grid A. For another example, if the terminal detects that the A-IoT device with reflected signal strength exceeding a reflected signal strength threshold is located in grid A, the terminal can determine that it is in grid A.

[0140] In some embodiments, the first configuration information includes but is not limited to at least one of the following:

[0141] A-IoT execution condition information, first A-IoT measurement configuration information, first location configuration information;

[0142] The A-IoT execution condition information includes at least one of the following: information of one or more grids, one or more A-IoT devices, and one or more A-IoT measurement events; wherein the one or more grids include the target grid, the one or more A-IoT devices include the target A-IoT device, and the one or more A-IoT measurement events include the target A-IoT measurement event;

[0143] The first A-IoT measurement configuration information is used to indicate an A-IoT measurement configuration associated with the A-IoT execution condition information;

[0144] The first location configuration information is used to indicate the location configuration related to the A-IoT device.

[0145] For example, each candidate cell may be associated with a grid, each candidate cell may be associated with an A-IoT device, and each candidate cell may be associated with an A-IoT measurement event. Specifically, based on the information associated with candidate cell i, it is determined whether the A-IoT execution condition corresponding to candidate cell i is satisfied.

[0146] It should be noted that the A-IoT execution condition information may be information related to the A-IoT execution condition.

[0147] It should be noted that the A-IoT measurement configuration may be information related to the A-IoT measurement event.

[0148] Optionally, when a candidate cell corresponds to at least two execution conditions, the triggering condition for conditional switching of the candidate cell is met only when both of the at least two execution conditions are met. For example, if a candidate cell is configured with at least two A-IoT execution conditions, conditional switching for the candidate cell is triggered only after both of the at least two A-IoT execution conditions are met. The at least two execution conditions include at least one A-IoT execution condition.

[0149] In some embodiments, the first A-IoT measurement configuration information is an A-IoT measurement configuration corresponding to the target A-IoT measurement event. That is, measurements can be performed based on the first A-IoT measurement configuration information to determine whether the target A-IoT measurement event is satisfied.

[0150] In some embodiments, the first A-IoT measurement configuration information includes but is not limited to at least one of the following:

[0151] The identification information of the A-IoT device corresponding to the target grid or the identification information of the A-IoT device corresponding to the target A-IoT measurement event, relevant information of the measurement event based on the A-IoT reflected signal strength, and relevant information of the measurement threshold based on the A-IoT reflected signal strength.

[0152] Exemplarily, whether a terminal is in the target grid can be determined based on the identification information of the A-IoT device corresponding to the target grid. For example, if the A-IoT device closest to the terminal is the A-IoT device corresponding to the target grid, the terminal is in the target grid. For another example, if the A-IoT device with the highest reflected signal strength detected by the terminal is the A-IoT device corresponding to the target grid, the terminal is in the target grid. For another example, if the A-IoT device with a reflected signal strength exceeding a reflected signal strength threshold detected by the terminal is the A-IoT device corresponding to the target grid, the terminal is in the target grid.

[0153] Exemplarily, whether the terminal satisfies the target A-IoT measurement event can be determined based on the identification information of the A-IoT device corresponding to the target A-IoT measurement event. For example, if the A-IoT device closest to the terminal is the A-IoT device corresponding to the target A-IoT measurement event, then the terminal satisfies the target A-IoT measurement event. For another example, if the A-IoT device with the largest reflected signal strength detected by the terminal is the A-IoT device corresponding to the target A-IoT measurement event, then the terminal satisfies the target A-IoT measurement event. For another example, if the A-IoT device with the reflected signal strength exceeding the reflected signal strength threshold detected by the terminal is the A-IoT device corresponding to the target A-IoT measurement event, then the terminal satisfies the target A-IoT measurement event.

[0155] Identification information of A-IoT devices deployed in the network, cell grid information, A-IoT device information associated with each grid, and grid information associated with each A-IoT device.

[0156] In this embodiment, the terminal can obtain the deployment information, grid segmentation information, and association information between the A-IoT device and the grid based on the first location configuration information. Thus, upon detecting an A-IoT device, the terminal can determine the grid information in which the A-IoT device is located. Furthermore, the grid in which the terminal is located is determined based on the grid in which the A-IoT device is located, thereby determining whether the A-IoT execution conditions of the candidate cell are met.

[0157] In some embodiments, before the terminal receives the first configuration information from the network-side device, the conditional switching method 200 further includes:

[0158] The terminal sends first information to the network side device;

[0159] The first information includes but is not limited to at least one of the following: first indication information, first location information;

The first location information is used to indicate the location information of the terminal.

[0162] In this embodiment, the network-side device can configure the conditional handover execution condition based on the first information reported by the terminal to improve the conditional handover performance. For example, the configuration includes a location-related execution condition, such as when the UE reaches location B, the execution condition is considered to be met and the conditional handover is executed.

[0163] Optionally, the first information may be carried by at least one of the following:

[0164] RRC signaling, uplink control information (UCI), media access control control element (MAC CE).

[0165] In some embodiments, the first location information includes but is not limited to at least one of the following:

[0167] The proximity indication is used to indicate that the terminal is approaching or leaving at least one specific A-IoT device.

[0168] In this embodiment, by determining the grid position of the terminal in the network cell, the location information of the terminal can potentially be further utilized to improve communication performance.

[0169] Optionally, a specific A-IoT device may be configured by the network side, or a specific A-IoT device may be agreed upon by a protocol.

[0170] Optionally, the specific range may be agreed upon by a protocol, or the specific range may be configured by the network side, or the specific range may be determined by negotiation between the terminal and the network side device.

[0171] In some embodiments, the grid information of the terminal includes but is not limited to at least one of the following:

[0172] The grid where the A-IoT device closest to the terminal is located, as detected by the terminal;

[0175] The intersection of the grids where at least two A-IoT devices are located detected by the terminal;

[0176] The grid that appears most frequently among the grids where at least two A-IoT devices are located detected by the terminal;

[0177] The grid with the highest probability of appearing among the grids where at least two A-IoT devices detected by the terminal are located.

[0178] Exemplarily, the grid information of the terminal includes the intersection of grids of at least two A-IoT devices detected by the terminal. For example, in the A-IoT information, A-IoT device A is in grid 1 of cell 1, A-IoT device B is in grid 1 of cell 1 and grid 2 of cell 2, and A-IoT device C is in grid 1 of cell 1 and grid 2 of cell 2. Then the grid where the terminal is located is grid 1 of cell 1.

[0179] Exemplarily, the grid information where the terminal is located includes the grid that appears most frequently among the grids where at least two A-IoT devices are located detected by the terminal, or the grid that appears with the highest probability among the grids where at least two A-IoT devices are located detected by the terminal. In the A-IoT information, A-IoT device A is in grid 1 of cell 1, A-IoT device B is in grid 1 of cell 1 and grid 2 of cell 2, and A-IoT device C is in grid 3 of cell 1 and grid 3 of cell 2. Then the grid where the terminal is located is grid 1 of cell 1.

[0180] In some embodiments, the absolute position of the terminal includes but is not limited to at least one of the following:

[0181] The absolute location of the A-IoT device closest to the terminal detected by the terminal;

[0186] Exemplarily, the absolute position of the terminal includes the center position of the absolute positions of at least two A-IoT devices detected by the terminal, so that the distance between the terminal and the at least two A-IoT devices is equal or close.

[0187] For example, based on the absolute positions of two A-IoT devices, the midpoint is calculated to be the terminal location. Without loss of generality, expressing the position in coordinates, A-IoT device A is located at [X1, Y1], and A-IoT device B is located at [X2, Y2]. The UE location is then [(X1+X2) / 2, (Y1+Y2) / 2].

[0188] For another example, based on the absolute positions of three A-IoT devices, the center of the circumscribed circle of the triangle formed by the absolute positions of the three A-IoT devices is taken as the UE position.

[0192] The relative position of the A-IoT device whose reflected signal strength detected by the terminal exceeds the reflected signal strength threshold;

[0193] The average of the relative positions of at least two A-IoT devices detected by the terminal.

[0194] It should be noted that the relative position of an A-IoT device is the position information of the A-IoT device relative to a reference point. For example, the reference point is a specific absolute position, a base station position, or a TRP position.

[0195] Exemplarily, the relative position of the terminal includes the average value of the relative positions of at least two A-IoT devices detected by the terminal. If the relative position is a distance, the average value calculated based on the distance of at least two A-IoT devices is the terminal position.

[0196] For example, the relative position of the terminal may include the relative position of a randomly selected A-IoT device from at least two A-IoT devices detected by the terminal, or the relative position of an A-IoT device selected according to a specific rule from at least two A-IoT devices detected by the terminal. Optionally, the specific rule may be agreed upon by a protocol, or may be configured by the network side.

[0197] In some embodiments, the proximity indication includes, but is not limited to, at least one of the following:

[0199] an indication that the terminal is approaching or leaving at least one specific A-IoT device;

[0200] Indication of the terminal approaching or leaving all specific A-IoT devices.

[0201] The proximity can be understood as that the reflected signal strength of a specific A-IoT device measured by the UE exceeds a certain configured or agreed threshold; or, the distance between the UE and the specific A-IoT device is lower than a certain configured or agreed threshold.

[0202] Similarly, the departure can be understood as that the reflected signal strength of the specific A-IoT device measured by the UE is lower than the reflected signal strength threshold; or, the distance between the UE and the specific A-IoT device is higher than the reflected signal strength threshold.

[0203] Optionally, the reflected signal strength threshold for determining a proximity indication may be agreed upon by a protocol, or the reflected signal strength threshold for determining a proximity indication may be configured by the network side.
