[0168] FIG1A is a schematic diagram showing the architecture of a communication system according to an embodiment of the present disclosure.

[0169] As shown in FIG. 1A , a communication system 100 includes a terminal 101 and a first network device 102 .

[0170] In some embodiments, terminal 101 may be an Ambient-IoT terminal or device. Terminal 101 may not be equipped with a battery and may be excited and powered by received electromagnetic signals; or it may be equipped with a battery with a small amount of electrical storage capacity and obtain energy from the battery by obtaining external electromagnetic waves, thermal energy, kinetic energy, etc.

[0171] Optionally, the power acquisition and storage capabilities of the terminal 101 may vary depending on the type and working mode of the terminal 101. For example, the types of the terminal 101 may include the following:

[0172] Terminal A, also known as a Class I terminal, is incapable of independent signal generation and / or amplification. For example, device A uses backscatter or backscatter communication and does not have the ability to amplify downlink (DL) and / or uplink (UL) signals.

[0173] Terminal B, or Class II terminals, has energy storage capabilities but cannot independently generate signals. For example, if device B operates in backscatter mode, it can use stored energy for DL ​​and / or UL signal amplification.

[0174] Terminal C or the third type of terminal: has energy storage capabilities and can independently generate signals, such as a radio frequency (RF) module that actively sends signals, autonomously generates RF signals and sends uplink information.

[0175] Among the above-mentioned terminal 101 types, terminal C has the strongest capabilities and the highest terminal cost. Terminals A and B have weaker capabilities and lower terminal costs. Furthermore, since terminals A and B require backscattering and cannot actively transmit signals, their supported coverage range is smaller. However, the power consumption of terminal A or terminal B in this operating mode is lower than that of terminal C.

[0176] In some embodiments, the terminal 101 includes, for example, a mobile phone, a wearable device, an Internet of Things device, a car with communication function, a smart car, a tablet computer, a computer with wireless transceiver function, a virtual reality (VR) terminal device, an augmented reality (AR) terminal device, a wireless terminal device in industrial control, a wireless terminal device in self-driving, a wireless terminal device in remote medical surgery, a wireless terminal device in a smart grid, a wireless terminal device in transportation safety, a wireless terminal device in a smart city, and at least one of a wireless terminal device in a smart home, but is not limited thereto.

[0177] In some embodiments, the first network device 102 may include at least one of an access network device and a core network device.

[0178] Optionally, the access network device is, for example, a node or device that accesses the terminal to the wireless network. The access network device may include an evolved NodeB (eNB), a next generation evolved NodeB (ng-eNB), a next generation NodeB (gNB), a node B (NB), a home node B (HNB), a home evolved nodeB (HeNB), a wireless backhaul device, a radio network controller (RNC), a base station controller (BSC), a base transceiver station (BTS), a base band unit (BBU), a mobile switching center, a base station in a 6G communication system, an open base station (Open RAN), a cloud base station (Cloud RAN), a base station in other communication systems, and at least one of an access node in a wireless fidelity (WiFi) system, but is not limited thereto.

[0179] In some embodiments, in an Ambient-IoT scenario, as shown in FIG1B , the communication system 100 may further include: a continuous wave node (CWN), an uplink receiver (UR), and an energy source node (ESN), wherein the first network device 102 may serve as a downlink signal node (DSN). Alternatively, the network device 102 may be configured to implement at least one of the following functions: DSN, CWN, UR, or ESN.

[0180] Optionally, the DSN is used to send downlink information or indication information. The DSN can be either the first network device 102 such as a base station or a relay device such as a relay UE. The DSN can send indication information to the terminal 101 to trigger uplink transmission of the terminal 101.

[0181] Optionally, the CWN is used to transmit continuous electromagnetic waves (CWs). Terminal 101 can use CWs to transmit uplink information based on backscatter. The CWN can also provide an incentive for devices A and B to perform uplink transmissions based on backscatter. Furthermore, the CW can serve as an energy source (ES), providing energy to Terminal 101. Terminal 101 can receive and store CWs.

[0182] Optionally, the UR may be another terminal or user equipment (UE) other than the terminal 101, configured to receive uplink information sent by the Ambient-IoT terminal 101. For example, the UR may receive uplink information sent by the terminal 101 based on backscatter communication, or may receive uplink information actively transmitted by the terminal 101.

[0183] Optionally, the ESN is used to power the terminal 101. For example, the ESN is a function of device B and device C. Since device A has limited energy storage capabilities, ES signals other than CW may not be defined for device A. Alternatively, ES may also be used for device A.

[0184] In some embodiments, as shown in FIG1B , the Ambient-IoT communication system may include four links, for example: link 1 for transmitting downlink information, link 2 for receiving uplink information, link 3 for sending CW, and link 4 for sending charging signals.

[0185] Optionally, link 4 may be controlled by the network. For example, the network can control the ESN to enable or disable charging of terminal 101. The energy provided by the ESN can come from electromagnetic waves or non-electromagnetic waves. In this case, the ESN can better coordinate with network scheduling and other functions to ensure that terminal 101 is charged while minimizing the impact on terminal 101's communications. Alternatively, the ESN is not controlled by the network. In other words, terminal 101 flexibly collects energy based on its capabilities and the energy sources in the actual environment, such as electromagnetic or non-electromagnetic wave energy not controlled by the network, without a specific ESN node. In this case, link 4 can be considered non-existent.

[0186] Optionally, the nodes involved in the four links in the above embodiment, such as DSN, CWN, ESN, and UR, can be independently configured, or can be the same node or device, or two, three, or four of them can be configured as one node or device. For example, in some embodiments, link 4 can be omitted or not exist.

[0187] In some embodiments, the functions of the above-mentioned different nodes can be implemented or supported by a single device. For example, a single device supports the functions of multiple nodes or all of the above-mentioned nodes. Alternatively, a single device corresponds to a node with only one of the above-mentioned functions. The first network device 102 can coordinate the behavior of the above-mentioned different nodes, such as CWN, ESN, and UR devices, to support effective communication with the terminal 101.

[0188] In some embodiments, in an Ambient-IoT scenario, as shown in FIG1C , a communication system 100 may include a terminal 101, a first network device 102, and a second network device 103. Optionally, the second network device 103 is a continuous wave node (CWN).

[0189] In some embodiments, the number of devices or nodes in FIG. 1A , FIG. 1B , and FIG. 1C is for illustration only, and in actual applications, multiple devices or nodes may be used.

[0190] In some embodiments, the technical solution of the present disclosure can be applied to the Open RAN architecture. In this case, the interfaces between or within the access network devices involved in the embodiments of the present disclosure can be transformed into internal interfaces of the Open RAN, and the processes and information interactions between these internal interfaces can be implemented through software or programs.

[0191] In some embodiments, the access network device can be composed of a centralized unit (CU) and a distributed unit (DU), where the CU can also be called a control unit. The CU-DU structure can be used to split the protocol layer of the access network device, with the functions of some protocol layers centrally controlled by the CU, and the functions of the remaining part or all of the protocol layers distributed in the DU, which is centrally controlled by the CU, but is not limited to this.

[0192] In some embodiments, the core network device can be a device including one or more network elements, or it can be multiple devices or device groups, each including all or part of one or more network elements. The network element can be virtual or physical. The core network includes, for example, at least one of the Evolved Packet Core (EPC), the 5G Core Network (5GCN), and the Next Generation Core (NGC). Alternatively, the core network device refers to a network element with a specific function, such as the Access Management Function (AMF), the Service Management Function (SMF), etc.

[0193] It can be understood that the communication system described in the embodiment of the present disclosure is for the purpose of more clearly illustrating the technical solution of the embodiment of the present disclosure, and does not constitute a limitation on the technical solution provided by the embodiment of the present disclosure. Ordinary technicians in this field can know that with the evolution of the system architecture and the emergence of new business scenarios, the technical solution provided by the embodiment of the present disclosure is also applicable to similar technical problems.

[0194] The following embodiments of the present disclosure may be applied to the communication system 100 shown in FIG. 1A , FIG. 1B , or FIG. 1C , or a partial body thereof, but are not limited thereto.

[0195] The various entities shown in Figure 1A, Figure 1B or Figure 1C are examples. The communication system may include all or part of the entities in Figure 1A, Figure 1B or Figure 1C, and may also include other entities other than Figure 1A, Figure 1B or Figure 1C. The number and form of each entity are arbitrary. The connection relationship between the entities is an example. The entities may be connected or disconnected, and the connection may be in any manner, which may be direct or indirect, and may be wired or wireless.

[0196] The embodiments of the present disclosure can be applied to Long Term Evolution (LTE), LTE-Advanced (LTE-A), LTE-Beyond (LTE-B), SUPER 3G, IMT-Advanced, 4th generation mobile communication system (4G), 5th generation mobile communication system (5G), 5G new radio (NR), future radio access (FRA), new radio access technology (RAT), new radio (NR), new radio access (NX), future generation radio access (FX), Global System for Mobile communications (GSM (registered trademark)), CDMA2000, Ultra Mobile Broadband (UMB), IEEE 802.11 (Wi-Fi (registered trademark)), IEEE 802.16 (WiMAX (registered trademark)), IEEE 802.20, Ultra-WideBand (UWB), Bluetooth (registered trademark), Public Land Mobile Network (PLMN) networks, Device-to-Device (D2D) systems, Machine-to-Machine (M2M) systems, Internet of Things (IoT) systems, Vehicle-to-Everything (V2X), systems utilizing other communication processing methods, and next-generation systems based on and extending these. Furthermore, multiple systems may be combined (for example, a combination of LTE or LTE-A with 5G).

[0197] In the disclosed embodiment, the terminal 101 can communicate based on the backscattering method. Backscattering or backscatter communications is an extremely low-power modulation and transmission technology that uses the backscattering principle of radio frequency signals, and is a means to achieve the intelligent connection of all things. In backscatter communications, radio frequency signals such as electromagnetic waves are received by the terminal 101, and the internal circuit of the terminal 101 modulates the information to be transmitted on the basis of the incident electromagnetic wave through load impedance modulation and other methods, and then sends out the modulated electromagnetic wave carrying the information. There are many ways to modulate information, such as amplitude shift keying (ASK), frequency-shift keying (FSK) or phase-shift keying (PSK).

[0198] In the embodiment of the present disclosure, for a terminal 101 using a backscattering method, the workflow may include: the first network device 102 sends a downlink instruction to the terminal 101, and after receiving the downlink instruction, the terminal 101 sends a corresponding response to the first network device 102 or performs a corresponding operation. While the terminal 101 is sending data to the UR, it requires an energy source such as the second network device 102 to provide it with a CW for reflection (i.e., link 3 is required).

[0199] Optionally, CW typically has a constant amplitude. The frequency of the electromagnetic wave reflected by terminal 101 can be exactly the same as the CW frequency, or there can be some offset. The offset size depends on the hardware characteristics of terminal 101. For example, the offset may be a fixed value, or, if supported by the hardware of terminal 101, it may support multiple fixed values, or a dynamically adjustable value.

[0200] One possible approach to frequency resource utilization is to divide the available spectrum into multiple subchannels, with each subchannel occupying a fixed bandwidth and the subchannels being orthogonal in the frequency domain. Terminal 101 can be instructed by the network to use one or more of these subchannels for data transmission, or it can select one or more subchannels for data transmission using an algorithm.

[0201] For terminals using backscattering, their antennas have a relatively wide operating bandwidth, such as tens of megahertz. If a CW node transmits CWs at multiple frequencies within the operating bandwidth of terminal 101, terminal 101 will receive CWs at multiple frequencies and backscatter all of them. This means that terminal 101 is unable to reflect only the CW for its selected subchannel.

[0202] In this sense, which uplink subchannel the terminal 101 can use for uplink transmission actually depends on the frequency and offset capabilities of the CW.

[0203] In the embodiment of the present disclosure, it can be applied to the application scenario of warehouse inventory, which is an important application scenario in ambient IoT. In the inventory business mode of the radio frequency identification (RFID) system, for an RFID tag (tag), after receiving a query (query), it sets a counter value (counter) according to the Q value in the query, and the counter is less than or equal to the Q value (or the counter value is less than or equal to an upper limit value calculated based on Q, such as (2^Q)-1) or Q-1. If the counter is 0, the tag can start to backscatter and send uplink information. In one example, RN16 (16-bit random number) is used to temporarily characterize the tag ID. If the counter value is not 0, the tag does not send information and waits to receive a query retransmission (QueryRep). Each time the tag receives a QueryRep, the counter value is reduced by 1 until the counter value is reduced to 0, at which time the tag will switch to the reply state and backscatter the uplink information. If an ACK is received, the tag is considered to have successfully accessed. Otherwise, if an invalid ACK or an ACK with an erroneous RN16 is received, or if no corresponding command is received within the set period, the tag is considered to have failed to access.

[0204] In the disclosed embodiments, in an Ambient IoT network, various types of terminals exist. Terminals A and B require CWs for uplink transmission, while Terminal C does not. Furthermore, CWs may interfere with Terminal C's uplink transmission. Therefore, how to inventory these various types of terminals is a technical challenge that needs to be addressed.

[0205] FIG2 is an interactive diagram of a communication method according to an embodiment of the present disclosure. As shown in FIG2 , an embodiment of the present disclosure relates to a communication method, the method comprising:

[0206] Step S2101 : The first network device 102 sends downlink information to the terminal 101 .

[0207] In some embodiments, terminal 101 receives the downlink information.

[0208] Optionally, the terminal 101 is an Ambient IoT terminal.

[0209] Optionally, terminal 101 is terminal A, terminal B or terminal C.

[0210] Optionally, the type of terminal 101 is the first category, the second category, or the third category.

[0211] Optionally, the first type of terminal: uses backscatter to send uplink information and does not generate uplink information;

[0212] The second type of terminal: uses backscatter to send uplink information and generate uplink information;

[0213] The third type of terminal: autonomously generates radio frequency signals and sends uplink information.

[0214] In some embodiments, the downlink information includes query information and at least one query retransmission information.

[0215] Optionally, the query information is an inventory command, and the query resend information is an inventory resend command.

[0216] Optionally, the inventory command is the first command in a complete inventory process, and is used to initialize parameters related to the round inventory, for example, the parameters include at least two integer values, and the at least two integer values ​​are used to determine the uplink sending timing of different types of terminals.

[0217] Optionally, uplink transmission opportunities of different types of terminals do not overlap.

[0218] Optionally, this parameter includes parameters related to the data transmission format.

[0219] Optionally, at least two integer values ​​are used to determine uplink sending timings for different types of terminals.

[0220] Optionally, the uplink sending opportunities of the different types of terminals do not overlap.

[0221] In step S2102 , the terminal 101 determines a count value according to the type of the terminal 101 and at least two numerical values.

[0222] In some embodiments, the count value is an integer value.

[0223] The following three scenarios explain this step in detail.

[0224] Scenario 1: Considering that Category 1 or Category 2 terminals require CWs to transmit uplink information, Category 3 terminals require autonomously generated RF signals and do not require CWs to transmit uplink information, when a CW node transmits CWs for Category 1 or Category 2 terminals, this may affect the first network device 102's ability to receive uplink information transmitted by Category 3 terminals. Therefore, the transmission timings of Category 1 and Category 2 terminals using backscatter and Category 3 terminals not using backscatter can be separated.

[0225] In some embodiments, when the terminal 101 is a first type terminal or a second type terminal, the count value is determined using the first method. When the terminal 101 is a third type terminal, the count value is determined using the second method.

[0226] Optionally, the first manner is: determining that the count value C is less than or equal to a first value X1, that is, C≤X1, wherein the first value X1 is determined according to a minimum value of at least two integer values.

[0227] In one example, the minimum of the at least two integer values ​​is Q min , the first value X1=(2^Q min )-1 or X1=Q min -1.

[0228] Among them, 2^Q min It's Q of 2 min Power.

[0229] Optionally, the second manner is: determining that the count value C is greater than the first threshold T1 and less than or equal to the second value X2, that is, T1≤C≤X2, wherein the second value X2 is determined according to the maximum value of at least two integer values.

[0230] In one example, the maximum of the at least two integer values ​​is Q max , the second value X2=(2^Q max )-1 or X2=Q max -1.

[0231] Optionally, the first threshold T1 is the first value X1, that is, T1=X1;

[0232] Optionally, the first threshold T1 is the sum of the first value X1 and the first interval value K1, that is, T1=X1+K1, where K1 is greater than or equal to 0.

[0233] Optionally, the first interval value K1 is configured by the first network device 102 .

[0234] Optionally, the first interval value K1 is a static value configured by the first network device 102 .

[0235] Optionally, the first interval value K1 is a semi-static value configured by the first network device 102 .

[0236] Optionally, the first interval value K1 is indicated in the query information.

[0237] When the first threshold T1 is the first value X1, it is possible that the first or second type of terminal may miss detecting a query resend command (e.g., an inventory resend command) sent by the first network device 102, thereby causing the transmission timing of the first or second type of terminal to overlap with the transmission timing of the third type of terminal. The first threshold T1 is the sum of the first value X1 and the first interval value K1. When K1 is greater than 0, the first or second type of terminal can tolerate a maximum of K1 missed detections of a query resend command (e.g., an inventory resend command) by the first or second type of terminal. That is, as long as the number of missed detections of a query resend command (e.g., an inventory resend command) by the first or second type of terminal is less than or equal to K1, the transmission timing of the first or second type of terminal will not overlap with the transmission timing of the third type of terminal.

[0238] In some embodiments, when the terminal 101 is a first type terminal or a second type terminal, the second method is used to determine the count value. When the terminal 101 is a third type terminal, the first method is used to determine the count value.

[0239] In one example, the number of the at least two integer values ​​is 2, that is, the at least two integer values ​​only include Q min and Q max .

[0240] Second scenario: Considering that the first type of terminal does not have the uplink signal power amplification function, the first type of terminal has the uplink signal power amplification function (the maximum power amplification value may be 10-15dB). When receiving the same CW power, the uplink coverage range of the first type of terminal will be much smaller than the uplink coverage range of the second type of terminal. If the sending timing of the first type of terminal and the sending timing of the second type of terminal can be separated, then the third network device 103 can use a higher sending power at the sending timing of the first type of terminal and a relatively low sending power at the sending timing of the second type of terminal. This allows terminals of different types to have relatively similar uplink coverage and will not cause high-power interference to other terminals.

[0241] Furthermore, considering that the first type of terminal or the second type of terminal requires CW to send uplink information, the input power of CW required for the first type of terminal and the second type of terminal at similar positions is not the same. The first type of terminal requires a higher input power of CW. In one example, in order for the network side to normally receive the uplink signal backscattered by the first type of terminal, the power of CW required by the first type of terminal is 10dB higher than the power of CW required by the second type of terminal. The transmission timing of the first type of terminal is separated from the transmission timing of the second type of terminal, so that CW is sent at a higher power at the transmission timing of the first type of terminal, and CW is sent at a lower power at the transmission timing of the second type of terminal. By adjusting the power of CW, different types of terminals can achieve the required uplink coverage. It also avoids the situation where the transmission power of CW is too high at the transmission timing of the second type of terminal, causing unnecessary interference to other terminals.

[0242] In some embodiments, when the terminal 101 is a first type of terminal, the count value is determined using a first method. When the terminal 101 is a second type of terminal, the count value is determined using a second method.

[0243] Optionally, the first manner is: determining that the count value C is less than or equal to a first value X1, that is, C≤X1, wherein the first value X1 is determined according to a minimum value of at least two integer values.

[0244] In one example, the minimum of the at least two integer values ​​is Q min , the first value X1=(2^Q min )-1 or X1=Q min -1.

[0245] Optionally, the second manner is: determining that the count value C is greater than the first threshold T1 and less than or equal to the second value X2, that is, T1≤C≤X2, wherein the second value X2 is determined according to the maximum value of at least two integer values.

[0246] In one example, the maximum of the at least two integer values ​​is Q max , the second value X2=(2^Q max )-1 or X2=Q max -1.

[0247] Optionally, the first threshold T1 is the first value X1, that is, T1=X1

[0248] Optionally, the first threshold T1 is the sum of the first value X1 and the first interval value K1, that is, T1=X1+K1, where K1 is greater than or equal to 0.

[0249] Optionally, the first interval value K1 is configured by the first network device 102 .

[0250] Optionally, the first interval value K1 is a static value configured by the first network device 102 .

[0251] Optionally, the first interval value K1 is a semi-static value configured by the first network device 102 .

[0252] Optionally, the first interval value K1 is indicated in the query information.

[0253] When the first threshold T1 is the first value X1, it is possible that the first type of terminal may miss detecting a query resend command (e.g., an inventory resend command) sent by the first network device 102, thereby causing the transmission timing of the first type of terminal to overlap with the transmission timing of the second type of terminal. The first threshold T1 is the sum of the first value X1 and the first interval value K1. When K1 is greater than 0, the first type of terminal can tolerate up to K1 missed detections of query resend commands (e.g., an inventory resend command). In other words, as long as the number of missed detections of query resend commands (e.g., an inventory resend command) by the first type of terminal is less than or equal to K1, the transmission timing of the first type of terminal and the transmission timing of the second type of terminal will not overlap.

[0254] In some embodiments, when the terminal 101 is a first type terminal or a second type terminal, the second method is used to determine the count value. When the terminal 101 is a third type terminal, the first method is used to determine the count value.

[0255] In one example, the number of the at least two integer values ​​is 2, that is, the at least two integer values ​​only include Q min and Q max .

[0256] Scenario 3: Considering that the first type of terminals require CW and do not have the uplink signal power amplification function, the second type of terminals require CW and have the uplink signal power amplification function (the maximum power amplification value may be 10-15dB), and the third type of terminals need to independently generate RF signals to send uplink information without CW, the transmission timing of the first, second and third type of terminals can be separated.

[0257] In some embodiments:

[0258] When the terminal 101 is a first type terminal, the count value is determined using one of the first, third, and fourth methods.

[0259] When the terminal 101 is a second type terminal, the count value is determined using one of the other two methods among the first method, the third method, and the fourth method except the method used by the first type terminal.

[0260] When the terminal 101 is a third type terminal, the count value is determined using another one of the first, third, and fourth methods except the method used by the first type terminals and the method used by the second type terminals.

[0261] In one example,

[0262] When the terminal 101 is a first type terminal, the count value is determined using the first method.

[0263] When the terminal 101 is a second type terminal, the count value is determined using the third method.

[0264] When the terminal 101 is a third type terminal, the fourth method is used to determine the count value.

[0265] In another example,

[0266] When the terminal 101 is a first type terminal, the count value is determined using the third method.

[0267] When the terminal 101 is a second type terminal, the fourth method is used to determine the count value.

[0268] When the terminal 101 is a third type terminal, the count value is determined using the first method.

[0269] These two examples are used for illustration only, and other examples are not listed here.

[0270] Optionally, a third manner is: determining that the count value C is greater than the first threshold T1 and less than or equal to a third value X3, ie, T1≤C≤X3, wherein the third value X3 is determined according to a middle value of at least two integer values.

[0271] In one example, the minimum of the at least two integer values ​​is Q min , the first value X1=(2^Q min )-1 or X1=Q min -1.

[0272] In one example, the middle value of the at least two integer values ​​is Q mid , the third value X3=(2^Q mid )-1 or X3=Q mid -1.

[0273] Optionally, the first threshold T1 is the first value X1, that is, T1=X1;

[0274] Optionally, the first threshold T1 is the sum of the first value X1 and the first interval value K1, that is, T1=X1+K1, where K1 is greater than or equal to 0.

[0275] Optionally, the first interval value K1 is configured by the first network device 102 .

[0276] Optionally, the first interval value K1 is a static value configured by the first network device 102 .

[0277] Optionally, the first interval value K1 is a semi-static value configured by the first network device 102 .

[0278] When the first threshold T1 is the first value X1, it is possible that the first type of terminal may miss detecting a query resend command (e.g., an inventory resend command) sent by the first network device 102, thereby causing the transmission timing of the first type of terminal to overlap with the transmission timing of the second type of terminal. The first threshold T1 is the sum of the first value X1 and the first interval value K1. When K1 is greater than 0, the first type of terminal can tolerate up to K1 missed detections of query resend commands (e.g., an inventory resend command). In other words, as long as the number of missed detections of query resend commands (e.g., an inventory resend command) by the first type of terminal is less than or equal to K1, the transmission timing of the first type of terminal and the transmission timing of the second type of terminal will not overlap.

[0279] Optionally, a fourth manner is: determining that the count value C is greater than the second threshold value T2 and less than or equal to the second value X2, that is, T2≤C≤X2, wherein the second value X2 is determined according to the maximum value of at least two integer values.

[0280] In one example, the maximum of the at least two integer values ​​is Q max , the second value X2=(2^Q max )-1 or X2=Q max -1.

[0281] Optionally, the second threshold value T2 is a third value X3, that is, T2=X3;

[0282] Optionally, the second threshold T2 is the sum of the third value X3 and the second interval value K2, that is, T2=X3+K2, where K2 is greater than or equal to 0.

[0283] Optionally, the second interval value K2 is indicated in the query information.

[0284] Optionally, the second interval value K2 is configured by the first network device 102 .

[0285] Optionally, the second interval value K2 is a static value configured by the first network device 102 .

[0286] Optionally, the second interval value K2 is a semi-static value configured by the first network device 102 .

[0287] Optionally, the second interval value K2 is indicated in the query information.

[0288] When the second threshold T2 is the third value X3, it is possible that the second-type terminal may miss detecting a query resend command (e.g., an inventory resend command) sent by the first network device 102, thereby causing the second-type terminal's transmission timing to overlap with the third-type terminal's transmission timing. The second threshold T2 is the sum of the third value X3 and the second interval value K2. When K2 is greater than 0, the second-type terminal can tolerate up to K2 missed detections of query resend commands (e.g., an inventory resend command). In other words, as long as the number of missed query resend commands (e.g., an inventory resend command) by the second-type terminal is less than or equal to K2, the second-type terminal's transmission timing will not overlap with the third-type terminal's transmission timing.

[0289] In one example, the number of the at least two integer values ​​is 3, that is, the at least two integer values ​​only include Q min , Q mid and Q max .

[0290] Step S2103: Terminal 101 determines an uplink transmission timing according to the count value and at least one query retransmission information.

[0291] In some embodiments, each time the terminal 101 receives a query retransmission message, it decrements the count value by 1. When the count value decreases to 0, the start time of the uplink transmission opportunity is reached.

[0292] In some embodiments, in the first scenario:

[0293] The second network device 103 does not send continuous electromagnetic waves to the first category of terminals and the second category of terminals within the first time period L1;

[0294] Accordingly,

[0295] The first type of terminal and the second type of terminal send continuous electromagnetic waves but cannot receive continuous electromagnetic waves within the first time period T1.

[0296] Optionally, the first time period L1 is the time period between the end times of the reporting periods of two query retransmission information sent by the first network device 102, each of the query retransmission information includes at least two integer values, one of the two query retransmission information is the query retransmission information sent for the first time, and the other is the query retransmission information sent for the Nth time, and the N is the first value X1, and the first value X1 is determined based on the minimum value of the at least two integer values ​​corresponding to the one.

[0297] Optionally, the end time of the reporting period for querying the retransmission information may be a time corresponding to a set time length after the end time of querying the retransmission information.

[0298] Optionally, the set duration may be configured by the first network device 102 .

[0299] Optionally, the set duration may be agreed upon in an agreement.

[0300] Optionally, set the duration to 20 milliseconds.

[0301] In some embodiments, in the second scenario:

[0302] The second network device 103 does not send continuous electromagnetic waves to the first category of terminals and the second category of terminals in the second time period L2;

[0303] Accordingly,

[0304] The first type of terminal and the second type of terminal send continuous electromagnetic waves but cannot receive continuous electromagnetic waves during the second time period L2.

[0305] Optionally, the second time period L2 is the time period between the end times of the reporting periods of two query retransmission information sent by the second network device 103, each of the query retransmission information includes at least two integer values, one of the two query retransmission information is the query retransmission information sent for the Mth time, and the other is the query retransmission information sent for the Gth time, the M is the sum of the first value X1 and 1, the G is the second value X2, and the second value X2 is determined based on the maximum value of the at least two integer values.

[0306] In some embodiments, in the third scenario:

[0307] The second network device 103 sends continuous electromagnetic waves within a first power range to the first type of terminals in a first time period L1;

[0308] The second network device 103 sends continuous electromagnetic waves within a second power range to the second type of terminals in a second time period L2.

[0309] Corresponding:

[0310] The first type of terminal and the second type of terminal receive continuous electromagnetic waves within a first power range during a first time period L1;

[0311] The first type of terminal and the second type of terminal receive continuous electromagnetic waves within the second power range during the second time period T1.

[0312] In one example, the first power range is [P1L-P1H], and the second power range is [P2L-P2H].

[0313] Step S2104: The second network device 103 determines a timing for sending continuous electromagnetic waves according to at least one query retransmission information.

[0314] In some embodiments, step S2104 may be performed between step S2102 and step S2103.
