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 auxiliary devices. This embodiment of the present application does not limit this.

[0061] To facilitate a better understanding of the embodiments of the present application, A-IoT is explained.

[0062] A-IoT devices have ultra-low complexity and ultra-low power consumption.

[0063] 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.

[0064] A-IoT devices have low overall power consumption, including low-power signal reception and low-power signal transmission. Due to the low overall power consumption, communication energy can come from environmental sources such as wind energy, kinetic energy, thermal energy, and radio frequency (RF) signals.

[0065] A-IoT devices can be classified based on energy source, energy storage capability, passive or active emission, etc., and can specifically include the following types of devices:

[0066] Passive Device: No independent signal generation / amplification, communication via backscatter.

[0067] Semi-passive devices also fall into the passive device category. They have energy storage but no independent signal generation. They communicate via backscatter, and the use of stored energy can include amplification of reflected signals.

[0068] Active Device: It has energy storage and independent signal generation capabilities, that is, it has active RF components for transmission.

[0069] To facilitate a better understanding of the embodiments of the present application, backscatter communication (BSC) is described.

[0070] 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.

[0071] 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.

[0072] 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.

[0073] 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:

[0074] 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.

[0075] 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).

[0076] 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.

[0077] To facilitate a better understanding of the embodiments of the present application, the A-IoT data / service types are explained.

[0078] 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).

[0079] 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.

[0080] 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.

[0081] 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.

[0082] 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 data from tags is also known as inventory counting or stocktaking. Specifically, after the reader sends a query command (Query), the tag responds with a reply (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 subsequent data (such as PC / XPC, electronic product code (EPC), etc.) to the reader.

[0083] As shown in FIG4 , 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.

[0084] Table 1

[0085] Table 2

[0086] To facilitate a better understanding of the embodiments of the present application, the RFID inventory process and anti-collision are explained.

[0087] Specifically, the RFID inventory process and anti-collision process may include the following steps 1 to 4.

[0088] Step 1: The reader is first powered on and reset, and sends a Select command to indicate that the corresponding matching conditions select this tag; the tag immediately switches to the Ready state.

[0089] Step 2: The reader sends a query command, and the tag determines whether to respond based on the inventory mark and the select mark.

[0090] The Query command starts an inventory cycle. The Query command contains the Q value. The tag (Tag) is in (0,2 Q -1) generates a random number as the initial value of the slot counter.

[0091] If the matching condition is met and the slot timer value is not 0, the arbitration state is immediately entered.

[0092] Then send a query response (Query_Rep) command to reduce the slot counter value by 1;

[0093] The QueryAdjust command can change the Q value and let the tag generate a new random number (0,2 Q -1) as the value of the slot counter.

[0094] If the matching condition is met and the slot counter is 0, the RN16 is responded and the state is immediately switched to the Reply state.

[0095] Step 3: The reader sends an ACK (RN16) command. The tag responds with the PC, ECP, and CRC-16 parameters and enters the Acknowledged state.

[0096] If a reader receives responses from multiple tags at the same time, it may not be able to process multiple tags' responses at once, and a collision is considered. The reader may not send an ACK. If a tag does not receive an ACK, the counters of these tags are randomly incremented by 0 or 1.

[0097] Step 4: In the Acknowledged state, after receiving the REQ_RN (RN16) command, the tag responds with RN16 and switches to the Open or Secured state. The reader can then perform read and write operations on the tag.

[0098] 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.

[0099] FIG5 is a schematic flow chart of a method 200 for assisting communication according to an embodiment of the present application. As shown in FIG5 , the method 200 for assisting communication may include at least part of the following contents:

[0100] S210, when a first condition is met, the first device obtains auxiliary information from the auxiliary device;

[0101] The first condition includes at least one of the following: the first device is configured with first configuration information, a first event is triggered, the first device is in a target area, and the first device is in a specific state within the valid time of the first configuration information and the valid time for obtaining auxiliary information.

[0102] It should be understood that FIG5 shows the steps or operations of the method 200 for assisting communication, but these steps or operations are merely examples, and the present application may also perform other operations or variations of the operations in FIG5 .

[0103] In an embodiment of the present application, when the first condition is met, the first device obtains auxiliary information from the auxiliary device. Thus, the first device can obtain auxiliary information from the auxiliary device on demand based on the first condition, which reduces the power consumption of the first device compared to the first device continuously detecting auxiliary information.

[0104] Exemplarily, the first condition includes at least one of the following: within the validity period of the first configuration information, and within the validity period for obtaining auxiliary information. Specifically, the first device obtains the auxiliary information from the auxiliary device within the validity period of the first configuration information, or the first device obtains the auxiliary information from the auxiliary device within the validity period for obtaining auxiliary information. That is, the first device only needs to obtain the auxiliary information from the auxiliary device within a specific time range, thereby facilitating energy saving for the first device.

[0105] Exemplarily, the first condition includes the first device being in a target area. Specifically, the target area may be an area where the communication performance of the first device is poor or limited (such as an elevator, basement, tunnel, airplane, train, ship, etc.). When the first device is in the target area, it obtains auxiliary information from the auxiliary device. That is, the first device only needs to obtain auxiliary information from the auxiliary device in the specific area, thereby facilitating energy conservation for the first device.

[0106] In this embodiment, the first event is triggered, which can also be expressed as: the first event is satisfied, or similar descriptions.

[0107] In some embodiments, the auxiliary equipment includes but is not limited to at least one of the following:

[0108] A-IoT devices, Bluetooth devices, and wireless LAN devices.

[0109] For example, an A-IoT device may also be an A-IoT terminal, a Passive-IoT device, an Ambient Energy (AMP) device, a zero-power device, a zero-power terminal, a low-power IoT device, an IoT device, a transponder, a tag, a Radio Frequency Identification (RFID) tag, etc. Such devices have low overall power consumption, including low-power signal reception and low-power signal transmission. Due to the low overall power consumption, the energy for communication can come from the environment, such as wind energy, kinetic energy, thermal energy, and radio frequency (RF) signals.

[0110] In some embodiments, the first device may be a device that communicates with the auxiliary device, and the first device includes but is not limited to at least one of the following: a reader or a reader / writer device, a terminal, a relay device, and a repeater.

[0111] Exemplarily, the reader / writer or the reading / writing device may be a module in the terminal.

[0112] For example, taking the first device as a terminal (UE) and the auxiliary device as an A-IoT device as an example, the network side can instruct the UE to detect A-IoT devices or obtain information about A-IoT devices in specific areas (such as elevators, basements, tunnels, airplanes, trains, ships, etc.). From the perspective of the UE, the UE has A-IoT capabilities (that is, it can serve as a reader or reader-writer device for A-IoT devices), which is called an A-IoT capable UE. In this case, the UE has 3GPP communication capabilities and A-IoT capabilities. The A-IoT capable UE can inventory A-IoT devices and obtain auxiliary information to determine the location of A-IoT devices or the UE location, as well as to enhance 3GPP communications.

[0113] In some embodiments, in the above S210, the first device may obtain the auxiliary information from the auxiliary device by at least one of the following methods:

[0114] The auxiliary device is detected, the auxiliary device is inventoried, and information of the auxiliary device is read.

[0115] Exemplarily, the first device obtains auxiliary information by detecting an auxiliary device. Specifically, detecting an auxiliary device means detecting whether the auxiliary device exists. In this case, the auxiliary information may include, for example, presence information of the auxiliary device or identification information of the auxiliary device. For example, if the signal strength of the auxiliary device is detected to be greater than or equal to a specific threshold, the first device obtains auxiliary information (such as the presence information of the auxiliary device or the identification information of the auxiliary device) from the auxiliary device.

[0116] Exemplarily, the first device obtains auxiliary information (e.g., identification information of the auxiliary device) through an inventory auxiliary device. Specifically, inventory auxiliary device means obtaining auxiliary information through an inventory process. In this case, the auxiliary information may include, for example, identification information of the auxiliary device. For example, the inventory process includes the first device sending an inventory command such as select, query, or paging, and receiving the auxiliary information sent by the auxiliary device.

[0117] Exemplarily, the first device obtains the auxiliary information by reading information or data of the auxiliary device. For example, the auxiliary information may include identification information of the auxiliary device.

[0118] In some embodiments, the auxiliary communication method 200 further includes:

[0119] The first device receives the first configuration information from the second device.

[0120] Optionally, before the first device obtains the auxiliary information from the auxiliary device, the first device receives the first configuration information from the second device.

[0121] Optionally, the first configuration information is used to configure the first device to obtain relevant parameters of auxiliary information from the auxiliary device, or the first configuration information is used to configure the first device to perform communication enhancement based on the auxiliary device.

[0123] Network-side equipment (such as access network equipment or core network equipment), relay equipment, intermediate nodes, application functions (AF), and third-party servers.

[0125] In some embodiments, the first configuration information is generated by the second device, or the first configuration information is generated by the second device based on third configuration information obtained from a third device, or the first configuration information is determined by the first device. Optionally, the third configuration information includes part or all of the first configuration information.

[0126] For example, the first configuration information generated by the second device may be applicable to one or more cells (such as a serving cell, a neighboring cell, etc.), for example, one or more cells (such as a serving cell, a neighboring cell, etc.) within the coverage of the second device.

[0127] For example, the first configuration information generated by the second device may be applicable to a specific area (such as an elevator, basement, tunnel, airplane, train, ship, etc.), for example, a specific area within the coverage range of the second device.

[0128] Optionally, the third device includes but is not limited to at least one of the following:

[0129] Core network equipment, application function (AF), and third-party servers.

Specifically, the target frequency band, target frequency point, target cell, target TTT duration, target power control step size, etc. are more suitable for use in these areas, thereby improving the communication performance of the first device in these areas.

Optionally, the information related to the target operation includes, but is not limited to, at least one of the following: the target frequency band, the target frequency point, the frequency point or identification information of the target cell, the index information of the target beam, the target TTT duration, and the target power control step size.

[0178] Optionally, the periodic information for obtaining the auxiliary information may be agreed upon by a protocol, or the periodic information for obtaining the auxiliary information may be configured by the second device (eg, through the first configuration information or the second configuration information).

[0179] In some embodiments, before the first device obtains the auxiliary information from the auxiliary device, the auxiliary communication method 200 further includes:

[0180] The first device determines the first condition based on the first configuration information.

[0181] Optionally, the first condition may also be agreed upon by a protocol, which is not limited in the embodiments of the present application.
