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.

[0160] In some embodiments, the sixth network element is used to implement user identity authentication, but is not limited thereto.

[0161] In some embodiments, each of the above network elements may be independent of the core network device.

[0162] In some embodiments, each of the above network elements may be part of a core network device.

[0163] In some embodiments, the Ambient IOT server can be a service device or computing platform that can provide data processing and storage services for managing, processing, and storing Ambient IOT business data collected from the surrounding environment. Optionally, the Ambient IOT server can also provide other possible functions, including but not limited to user interface, data visualization, remote access, integration of third-party services or applications, etc. Optionally. The Ambient IOT server may be a physical server or a virtual server, which can be located locally (for example, in a smart home system) or in the cloud.

[0164] In more possible implementations, the communication system 100 may further include an intermediate node.

[0165] In some embodiments, the intermediate node may be a node that provides data forwarding functionality, or an intermediate node that assists other devices or nodes in sending or receiving data, for example, at least one of a relay, an Integrated Access and Backhaul (IAB) node, a user equipment (UE), and a repeater, but not limited thereto.

[0166] 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 proposed in 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 proposed in the embodiment of the present disclosure is also applicable to similar technical problems.

[0167] The following embodiments of the present disclosure may be applied to the communication system 100 shown in FIG1 , or a portion thereof, but are not limited thereto. The entities shown in FIG1 are illustrative only. The communication system may include all or part of the entities shown in FIG1 , or may include other entities outside of FIG1 . The number and form of the entities are arbitrary, and the entities may be physical or virtual. The connection relationships between the entities are illustrative only. The entities may be connected or disconnected, and the connection may be in any manner, including direct or indirect, wired or wireless.

[0168] 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 methods, and next-generation systems based on and extending these methods. Furthermore, multiple systems may be combined (for example, a combination of LTE or LTE-A with 5G).

[0169] In some embodiments, wireless communication design of ambient IoT devices can be implemented based on backscatter technology.

[0170] In some embodiments, in backscattering technology, when the radio frequency signal reaches the surface of an object, a portion of the signal will be reflected. The ambient IoT device can adjust the matching between the receiving antenna and the impedance according to the information to be sent to enhance the reflection of the incident radio frequency signal, and modulate the information to be sent onto the reflected signal to complete the transmission of the information.

[0171] It should be noted that backscattering can transmit signals without complex RF structures, which can reduce the use of devices such as power amplifiers, high-precision crystal oscillators, duplexers, and high-precision filters. It also does not require complex baseband processing processes, which can simplify the design of terminal equipment and reduce equipment costs.

[0172] In some embodiments, ambient IoT devices can be divided into two types: type 1 and type 2.

[0173] Type 1 Ambient IoT devices lack energy storage, independent signal generation, and amplification, and therefore rely on backscatter for uplink transmission. Type 2 Ambient IoT devices, on the other hand, have energy storage and independent signal amplification, and their uplink transmission can be generated internally or through backscatter.

[0174] It should be noted that the main difference between type 1 and type 2 Ambient IoT devices is that type 1 Ambient IoT devices need to rely on excitation signals for backscattering to achieve data transmission, while type 2 Ambient IoT devices can rely on excitation signals for backscattering to achieve data transmission, or rely on the energy inside the device to transmit data.

[0175] Optionally, whether it is a type 1 Ambient IOT device or a type 2 Ambient IOT device, there may be multiple network access methods.

[0176] Refer to Figure 2A, which is a schematic diagram of a network architecture according to an embodiment of the present disclosure. Taking the access network device as a base station as an example, as shown in Figure 2A, data (including uplink data and downlink data) can be directly sent and received between the Ambient IOT device and the base station.

[0177] Refer to Figure 2B, which is another network architecture diagram shown according to an embodiment of the present disclosure. Taking the access network device as a base station as an example, as shown in Figure 2B, data (including uplink data and downlink data) can be indirectly sent and received between the Ambient IOT device and the base station, and the intermediate node can play the function of data forwarding between the Ambient IOT device and the base station.

[0178] It should be noted that the above are only two exemplary access methods and do not constitute a limitation on the access methods of Ambient IOT devices.

[0179] There may be multiple Ambient IoT devices within the network coverage of the Ambient IoT system. Therefore, the Ambient IoT system needs to consider supporting command control of multiple Ambient IoT devices. If command control of multiple Ambient IoT devices is to be supported, uplink resource allocation of multiple Ambient IoT devices needs to be considered to reduce or avoid resource conflicts between multiple Ambient IoT devices.

[0180] FIG3 is an interactive diagram of a communication method according to an embodiment of the present disclosure. As shown in FIG3 , the embodiment of the present disclosure relates to a communication method, and the method includes:

[0181] Step S3101: A first communication device sends first information to an Ambient IoT device.

[0182] In some embodiments, the first communication device is a UE or an access network device (such as a base station (BS) or a core network device or an Ambient IOT server. For an introduction to the first communication device and the Ambient IOT device, please refer to the embodiment corresponding to Figure 1, which will not be repeated here.

[0183] In some embodiments, the name of the first communication device is not limited, and it may be, for example, a "first node" or the like.

[0184] In some embodiments, the ambient IoT device receives first information sent by the first communication device.

[0185] In some embodiments, the names of information, etc. are not limited to the names described in the embodiments, and terms such as "information", "message", "signal", "signaling", "report", "configuration", "indication", "instruction", "command", "channel", "parameter", "domain", "field", "symbol", "symbol", "codeword", "codebook", "codeword", "codepoint", "bit", "data", "program", and "chip" can be used interchangeably.

[0186] In some embodiments, the first communication device sends a first command message to the Ambient IoT device, where the first command message includes the first information. In some embodiments, the Ambient IoT device receives the first command message sent by the first communication device to receive the first information.

[0187] In some embodiments, the first command message may be used to request the Ambient IoT device to send a device code, and / or the first command message may be used to instruct the Ambient IoT device to perform subsequent operations.

[0188] Optionally, the device code may include an Electronic Product Code (EPC) and a Response Identifier (RN16), but is not limited thereto.

[0189] Optionally, subsequent operations performed by the Ambient IoT device may include a write operation, a read operation, a lock operation, a kill operation, etc., but is not limited thereto.

[0190] In some embodiments, the first command message may be at least one of query signaling, acknowledgement (ACK) signaling, read signaling, and write signaling, but is not limited thereto.

[0191] It should be noted that the above-mentioned method of using the first command message to carry the first information is only an exemplary implementation method. In more possible implementation methods, the first information can be an independent message without the need for other messages as a carrier.

[0192] Optionally, the first information is an independent message, and the first communication device may send the first information to the Ambient IOT device before sending the first command message; or, the first communication device may send the first information and the first command message to the Ambient IOT device at the same time; or, the first communication device may send the first information to the Ambient IOT device after sending the first command message. This is not limited in the embodiments of the present disclosure.

[0193] In some embodiments, the first information may be agreed upon in a protocol, and the Ambient IoT device may obtain the first information agreed upon in the protocol without the first communications device sending the first information. Alternatively, the uplink resource for the Ambient IoT device to send a first command response may be directly agreed upon in the protocol, and the Ambient IoT device may directly obtain the uplink resource agreed upon in the protocol without the first communications device sending the first information. Furthermore, the Ambient IoT device does not need to determine the uplink resource based on the first information.

[0194] In some embodiments, the first information is used by the Ambient IoT device to determine an uplink resource for sending a first command response.

[0195] Optionally, the first information may directly indicate the uplink resources for the Ambient IOT device to send a first command response; or, the first information may indicate the relevant parameters used by the Ambient IOT device to determine the uplink resources for sending a first command response, and the Ambient IOT device may determine the uplink resources for sending a first command response based on the parameters indicated by the first information.

[0196] In some embodiments, the terms "resource", "resource set", "resource group", "precoding", "precoder", "weight", "precoding weight", "quasi-co-location (QCL)", "transmission configuration indication (TCI) state", "spatial relation", "spatial domain filter", "transmission power", "phase rotation", "antenna port", "antenna port group", "layer", "the number of layers", "rank", "beam", "beam width", "beam angular degree", "antenna", "antenna element", "panel" and the like can be used interchangeably.

[0197] In some embodiments, the name of the first information is not limited, and it can be, for example, "resource indication information", "resource allocation information", etc.

[0198] In some embodiments, the first information includes at least one of first indication information, second indication information, and first parameter information, but is not limited thereto.

[0199] In some embodiments, the first information includes first indication information, where the first indication information is used to indicate an uplink frequency domain resource for the Ambient IoT device to send a first command response.

[0200] For example, the first indication information may be used to indicate a resource identifier of an uplink frequency domain resource for sending a first command response by the Ambient IoT device.

[0201] It should be noted that the uplink frequency domain resources allocated to different Ambient IoT devices for sending the first command response may be different. In other words, the uplink frequency domain resources may be device-specific, and for different Ambient IoT devices, the device-specific uplink frequency domain resources are independent of each other.

[0202] In some embodiments, the uplink frequency domain resource may be an uplink subchannel, an uplink subcarrier, etc., but is not limited thereto.

[0203] In some embodiments, terms such as "sub-carrier", "resource block (RB)", "physical resource block (PRB)", "sub-carrier group (SCG)", "resource element group (REG)", "PRB pair", "RB pair", and "resource element (RE)" can be used interchangeably.

[0204] Optionally, the first indication information can be used to indicate a channel index (index) to indicate the subchannel or subcarrier allocated by the first communication device to the Ambient IOT device through the channel index. The subchannel or subcarrier indicated by the channel index is also the uplink frequency domain resource for the Ambient IOT device to send the first command response.

[0205] In some embodiments, the first information includes second indication information, where the second indication information is used to indicate an uplink time domain resource for the Ambient IoT device to send a first command response.

[0206] Optionally, the second indication information may indicate the time domain resource location of the Ambient IoT device sending the first command response. For example, the second indication information may clearly indicate the specific location of the time domain resource of the Ambient IoT device sending the first command response.

[0207] Optionally, the second indication information may indicate a first time for the Ambient IoT device to send a first command response, where the first time is the time from when the Ambient IoT device receives the first information to when it sends the first command response.

[0208] It should be noted that, if the first command message is used as the carrier of the first information, the first time is the time elapsed from the Ambient IOT device receiving the first command message to sending the first command response.

[0209] In some embodiments, the first time may be determined by the first communication device based on the message size or message type of the first command message; or, the first time may be determined by the first communication device based on the expected message size or expected message type of the first command response.

[0210] In some embodiments, the first time is a single value, or the first time is a value range, that is, the first time can be a fixed value, or the first time can be a range of values.

[0211] For example, the first time may be a moment, or the first time may be a period of time.

[0212] In some embodiments, terms such as "moment", "time point", "time", and "time position" can be replaced with each other, and terms such as "duration", "period", "time window", "window", and "time" can be replaced with each other.

[0213] In some embodiments, for multiple Ambient IoT devices, the uplink time domain resources received by these Ambient IoT devices meet a first threshold. That is, for any Ambient IoT device, the uplink time domain resources received by it and the uplink time domain resources received by other Ambient IoT devices meet the first threshold.

[0214] Optionally, the first threshold is a lower limit of the time interval between two uplink time domain resources. That is, for multiple Ambient IoT devices, the time interval between the uplink time domain resources received by these Ambient IoT devices is greater than or equal to the first threshold.

[0215] Taking the uplink resource of instructing an Ambient IoT device to send a first command response by indicating the time elapsed from the Ambient IoT device receiving the first command message to the time it sends the first command response as an example, for multiple Ambient IoT devices, the time interval between the times received by any two Ambient IoT devices is greater than or equal to a first threshold. For example, if one Ambient IoT device receives the message at time t1 and another Ambient IoT device receives the message at time t2, then the time interval between t1 and t2 is greater than or equal to the first threshold.

[0216] In some embodiments, the first threshold is determined by the first communication device itself and sent to the Ambient IOT device by the first communication device; or, the first threshold is configured by other communication devices for the first communication device or the Ambient IOT device; or, the first threshold is agreed upon by a protocol, but is not limited thereto.

[0217] Optionally, the first threshold is sent by the first communication device to the Ambient IOT device, and the first information can be used as a carrier of the first threshold. That is, the first information can include the first threshold, so that when the first communication device sends the first information to the Ambient IOT device, the first threshold can be sent to the Ambient IOT device together. However, this is not limited to the above. The first communication device can also use other methods to send the first threshold to the Ambient IOT device.

[0218] In some embodiments, the first communication device may further send second information to the Ambient IoT device, where the second information is used to indicate a time when the Ambient IoT device stops sending a response to the first command.

[0219] In some embodiments, the ambient IoT device may receive the second information sent by the first communication device, and stop sending the first command response according to the second information.

[0220] In some embodiments, the name of the second information is not limited, and it can be, for example, "stop sending instruction", "time indication information", etc.

[0221] In some embodiments, the uplink resource indicated by the first information may be an uplink resource configured for one or more Ambient IOT devices, or the uplink resource indicated by the first information may be an uplink resource configured for one or more command responses, and the uplink resource may be an uplink frequency domain resource and / or an uplink time domain resource.

[0222] In some embodiments, the uplink resource may be an uplink resource set (i.e., an uplink frequency domain resource set and / or an uplink time domain resource set), and the uplink resource set may be configured for the Ambient IOT device. For example, the uplink resource set may be specifically configured for a certain Ambient IOT device; or, the uplink resource set may be configured for multiple Ambient IOT devices, and multiple Ambient IOT devices may share the uplink resources in the uplink resource set.

[0223] In some embodiments, the uplink resource set may also be configured for a command response. For example, the uplink resource set may be specifically configured for a certain command response, and the uplink resource set is specifically used to transmit the command response; or, the uplink resource set may be configured for multiple command responses, and multiple command responses may be transmitted in the uplink resource set.

[0224] In some embodiments, the first information includes first parameter information, and the first parameter information is used by the Ambient IoT device to determine a timing for sending the first command response.

[0225] Optionally, the first parameter information may directly indicate to the Ambient IoT device the timing of sending the first command response.

[0226] Alternatively, the first parameter information may indicate relevant parameters used by the Ambient IoT device to determine the timing of sending the first command response, and the Ambient IoT device may determine the timing of sending the first command response based on the first parameter information. For example, the first parameter information may be used by the Ambient IoT device to determine second parameter information, and the second parameter information is used to indicate the timing of sending the first command response by the Ambient IoT device.

[0227] It should be noted that the first parameter information sent by the first communication device to different Ambient IOT devices may be the same, but the rules used by different Ambient IOT devices to generate the second parameter information based on the first parameter information may be different. Therefore, different Ambient IOT devices can generate different second parameter information based on the same first parameter information; or, the first parameter information sent by the first communication device to different Ambient IOT devices may be different, and different Ambient IOT devices can generate different second parameter information based on different first parameter information.

[0228] Optionally, the rules used by the Ambient IOT device to generate the second parameter information based on the first parameter information may be pre-configured for each Ambient IOT device, and the rules configured for different Ambient IOT devices may be different; or, the first communication device may indicate to the Ambient IOT device the rules for generating the second parameter information based on the first parameter information, and the generation rules indicated for different Ambient IOT devices may be different.

[0229] Optionally, the first information can be used as a carrier, that is, the first information can include a rule for generating the second parameter information based on the first parameter information, so that when the first communication device sends the first information to the Ambient IOT device, the rule for generating the second parameter information based on the first parameter information can be sent to the Ambient IOT device at the same time, but not limited to this, the first communication device can also use other methods to send the rules to the Ambient IOT device.

[0230] In more possible implementations

[0231] Step S3102: The Ambient IoT device determines an uplink resource for sending a first command response based on the first information.

[0232] In some embodiments, the first information includes first indication information, where the first indication information is used to indicate an uplink frequency domain resource for the Ambient IoT device to send a first command response.

[0233] Optionally, the first indication information is used to indicate the resource identifier of the uplink frequency domain resource for the Ambient IOT device to send the first command response, and the Ambient IOT device can determine the uplink frequency domain resource indicated by the resource identifier as the uplink resource for sending the first command response.

[0234] For example, the first indication information is used to indicate a channel index, and the Ambient IoT device may determine the subchannel or subcarrier indicated by the channel index as the uplink frequency domain resource for sending the first command response.

[0235] In some embodiments, the uplink frequency domain resource indicated by the first indication information is an uplink frequency domain resource set, which can be configured for one or more Ambient IOT devices, or the uplink frequency domain resource set can be configured for one or more command responses.

[0236] In some embodiments, the uplink frequency domain resource set is specifically configured for the Ambient IoT device, and the Ambient IoT device may determine the uplink frequency domain resource set as the uplink resource for sending the first command response.

[0237] In some embodiments, the uplink frequency domain resource set is shared by multiple Ambient IoT devices, and the Ambient IoT device may select an uplink frequency domain resource from the uplink frequency domain resource set as the uplink resource for sending the first command response.

[0238] In some embodiments, the uplink frequency domain resource set is specially configured for the first command response, and the Ambient IoT device may determine the uplink frequency domain resource set as the uplink resource for sending the first command response.

[0239] In some embodiments, the uplink frequency domain resource set is shared by multiple command responses, and the Ambient IOT device may select an uplink frequency domain resource from the uplink frequency domain resource set as the uplink resource for sending the first command response.

[0240] Optionally, in the case where the Ambient IOT device selects an uplink frequency domain resource from the uplink frequency domain resource set as the uplink resource for sending the first command response, the Ambient IOT device can randomly select the uplink frequency domain resource from the uplink frequency domain resource set; or, the Ambient IOT device can select the uplink frequency domain resource from the uplink frequency domain resource set according to a predefined rule.

[0241] Optionally, when selecting uplink frequency domain resources according to predefined rules, the Ambient IOT device may select uplink frequency domain resources based on the device identifier of the Ambient IOT device and the number of uplink frequency domain resources included in the uplink frequency domain resource set.

[0242] For example, the ambient IOT device can perform a modulo operation on its own device identifier and the number of uplink frequency domain resources included in the uplink frequency domain resource set. The result obtained by the modulo operation can be used as the resource identifier used for resource selection, that is, the uplink frequency domain resource indicated by the resource identifier obtained by the modulo operation can be determined as the uplink frequency domain resource for sending the first command response.

[0243] Optionally, the device identifier may be a temporary identifier of the Ambient IoT device, or the device identifier may be a unique identifier (ID) of the Ambient IoT device, but is not limited thereto.

[0244] In some embodiments, the first information includes second indication information, where the second indication information is used to indicate an uplink time domain resource for the Ambient IoT device to send a first command response.

[0245] Optionally, the second indication information directly indicates the time domain resource position for the Ambient IoT device to send the first command response, and the Ambient IoT device may determine the uplink time domain resource corresponding to the time domain resource position as the uplink resource for sending the first command response.

[0246] Optionally, the second information indicates a first time for the Ambient IoT device to send a first command response, and the Ambient IoT device may send the first command response after receiving the first information for the first time. For an introduction to the first time, see step S3101, which will not be repeated here.

[0247] It should be noted that, regardless of whether the second indication information indicates a specific time domain location or a first time, the uplink frequency domain resources indicated by the second indication information may be an uplink time domain resource set. For example, if the second indication information indicates a time domain location, the uplink time domain resource set may include multiple time domain locations; or, if the second indication information indicates a first time, the uplink time domain resource set may include at least one first time.

[0248] In some embodiments, the uplink time domain resource set may be configured for one or more Ambient IOT devices, or the uplink time domain resource set may be configured for one or more command responses.

[0249] In some embodiments, the uplink time domain resource set is specifically configured for the Ambient IoT device, and the Ambient IoT device may determine the uplink time domain resource set as the uplink resource for sending the first command response.

[0250] In some embodiments, the uplink time domain resource set is shared by multiple Ambient IoT devices, and the Ambient IoT device may select an uplink time domain resource from the uplink time domain resource set as the uplink resource for sending the first command response.

[0251] Optionally, the first information may include first configuration indication information, which can be used to indicate which Ambient IOT device or devices the uplink time domain resource set is configured for, so that the Ambient IOT device can determine based on the first configuration indication information whether the uplink resource is specifically configured for itself or configured for multiple Ambient IOT devices including itself, thereby determining the uplink resource for sending the first command response based on the determination result.

[0252] In some embodiments, the uplink frequency domain resource set is specially configured for the first command response, and the Ambient IoT device may determine the uplink frequency domain resource set as the uplink resource for sending the first command response.

[0253] In some embodiments, the uplink time domain resource set is shared by multiple command responses, and the Ambient IoT device may select an uplink time domain resource from the uplink time domain resource set as the uplink resource for sending the first command response.

[0254] Optionally, the first information may include second configuration indication information, which may be used to indicate which command response or responses the uplink time domain resource set is used to transmit, so that the Ambient IOT device may determine, based on the second configuration indication information, whether the uplink resource is specifically used to send the first command response, or to send multiple command responses including the first command response, thereby determining the uplink resource for sending the first command response based on the determination result.

[0255] Optionally, in the case where the Ambient IOT device selects an uplink time domain resource from the uplink time domain resource set as the uplink resource for sending the first command response, the Ambient IOT device can randomly select the uplink time domain resource from the uplink time domain resource set; or, the Ambient IOT device can select the uplink time domain resource from the uplink time domain resource set according to a predefined rule, which is not limited in the embodiments of the present disclosure.

[0256] In some embodiments, the first communication device may further send a second message to the Ambient IOT device, where the second information is used to indicate the time when the Ambient IOT device stops sending a response to the first command. Thus, the Ambient IOT device may further receive the second information, thereby determining the time to stop sending a response to the first command based on the second information.

[0257] In some embodiments, the first information includes first parameter information, and the first parameter information is used by the Ambient IoT device to determine a timing for sending the first command response.

[0258] In some embodiments, the first parameter information directly indicates the sending timing of the first command response. The Ambient IOT device can directly use the sending timing indicated by the first parameter information as the sending timing of the first command response, thereby sending the first command response at the corresponding sending timing.

[0259] In some embodiments, the first parameter information indicates relevant parameters used by the Ambient IoT device to determine the sending timing of the first command response, and the Ambient IoT device may determine the sending timing of the first command response based on the first parameter information.

[0260] In some embodiments, the Ambient IoT device may determine second parameter information based on the first parameter information, where the second parameter information is used to indicate a timing for the Ambient IoT device to send a first command response.

[0261] Optionally, the Ambient IOT device and the first command response each have their own corresponding priority information. The Ambient IOT device can determine the second parameter information based on the first parameter information and the priority information of the Ambient IOT device; or, the Ambient IOT device can determine the second parameter information based on the first parameter information and the priority information of the first command response.

[0262] Optionally, the priority information of the Ambient IOT device may be pre-configured; or, the priority information of the Ambient IOT device may be determined by the first communication device based on device information of the Ambient IOT device, where the device information includes but is not limited to device type, device parameters, etc.

[0263] Optionally, the priority information of the Ambient IOT device is determined by the first communication device based on the device information of the Ambient IOT device. The first information can be used as a carrier of the priority information of the Ambient IOT device, that is, the first information can include the priority information of the Ambient IOT device, so that when the first communication device sends the first information to the Ambient IOT device, the priority information of the Ambient IOT device can be sent to the Ambient IOT device at the same time. However, this is not limited to the above. The first communication device can also use other methods to send the priority information of the Ambient IOT device to the Ambient IOT device.

[0264] Optionally, the second parameter information may be randomly generated or generated based on a predefined rule, which is not limited in the embodiment of the present disclosure.

[0265] The second parameter information is generated based on a predefined rule. For example, the first parameter information is N, and the second parameter information determined based on the first parameter information is 2. N -1, N can be any value.

[0266] It should be noted that different priority information may correspond to different parameter value ranges. For an Ambient IoT device and a first command response with the same priority information, the corresponding parameter value ranges may be the same or different. In other words, the priority information of the Ambient IoT device and the priority information of the first command response may each correspond to a set of parameter value ranges, or the priority information of the Ambient IoT device and the priority information of the first command response may correspond to the same set of parameter value ranges.

[0267] In some embodiments, when determining the second parameter information based on the first information and the priority information, the second parameter information may be determined according to the first parameter information indicated by the first information within a parameter value range corresponding to the priority information.

[0268] In some embodiments, the value indicated by the second parameter information can be used as the initial value of the timer. The Ambient IOT device can generate the initial value of the timer based on the first parameter information and start the timer. The Ambient IOT device can use the time when the timer expires as the timing to send the first command response.

[0269] It should be noted that the time when the timer expires is the time when the initial value of the timer becomes 0 after the countdown.

[0270] In some embodiments, the second parameter information can be used as a random number, and the Ambient IOT device can generate a random number based on the first parameter information, and the first communication device can repeatedly send command messages to the Ambient IOT device. Each time the Ambient IOT device receives a command message sent by the first communication device, it can reduce the random number by 1, and the Ambient IOT device can use the time when the random number is reduced to the first value as the timing of sending the first command response.

[0271] Optionally, the command message repeatedly sent by the Ambient IoT device may be the first command message or the second command message. That is, after sending the first command message to the Ambient IoT device, the first communication device may continue to repeatedly send the first command message to the Ambient IoT device; or, after sending the first command message to the Ambient IoT device, the first communication device may stop sending the first command message and instead repeatedly send the second command message to the Ambient IoT device.

[0272] It should be noted that, in the process of the first communication device repeatedly sending the command message, the Ambient IOT device may continuously perform a decrement operation on the generated second parameter information according to the sending status of the command message.

[0273] For example, the first communication device may repeatedly send the first command message to the Ambient IOT device. Each time the Ambient IOT device receives a first command message, it may reduce the random number by 1, thereby using the time when the random number is reduced to the first value as the timing for sending the first command response.

[0274] Alternatively, the first communication device may repeatedly send the second command message to the Ambient IOT device. Each time the Ambient IOT device receives a second command message, it may reduce the random number by 1, thereby using the time when the random number is reduced to the first value as the timing for sending the first command response.

[0275] Optionally, the Ambient IOT device can determine whether the currently received command message and the previously received command message are for the same command based on the indication in the command message (including the first command message and the second command message) or the content of the command message. If so, the Ambient IOT device can reduce the random number by 1; if not, the Ambient IOT device can keep the random number unchanged.

[0276] Optionally, the second command message may be a query reply (Query Reply, QueryRep) signaling, or an access command (Write, Read, Lock, Kill), but is not limited thereto.

[0277] Optionally, the first value may be 0 or other specific values, and the embodiment of the present disclosure does not limit the value of the first value.

[0278] It should be noted that the first information may include any one of the first indication information, the second indication information, and the first parameter information, or the first information may include two or three of the first indication information, the second indication information, and the first parameter information. That is, the above three resource configuration methods can be configured independently or simultaneously. For example, the first communication device can configure specific frequency domain resources or / and specific time domain resources (or time domain resource range) for the Ambient IOT device, and the Ambient IOT device can send a first command response on the configured resources; or, based on the first parameter information, the Ambient IOT device can send a first command response on specific frequency domain resources and / or specific time domain resources (or time domain resource range).

[0279] Step S3103: The Ambient IoT device sends a first command response to the first communication device on the uplink resource.

[0280] In some embodiments, the ambient IoT device may send a first command response to the first communication device on the determined uplink frequency domain resources.

[0281] In some embodiments, the ambient IoT device may send a first command response to the first communication device on the determined uplink time domain resource.

[0282] In some embodiments, the Ambient IoT device may send a first command response to the first communication device when the determined sending opportunity is reached.

[0283] In some embodiments, "obtain", "get", "get", "receive", "transmit", "bidirectional transmission", "send and / or receive" can be interchangeable, and can be interpreted as receiving from other entities, obtaining from protocols, obtaining from higher layers, obtaining by self-processing, autonomous implementation, etc.

[0284] In some embodiments, terms such as "send", "transmit", "report", "download", "transmit", "bidirectional transmission", "send and / or receive" can be used interchangeably.

[0285] In some embodiments, terms such as "certain", "preset", "preset", "setting", "indicated", "a certain", "any", and "first" can be interchangeable. "Specific A", "preset A", "preset A", "setting A", "indicated A", "a certain A", "any A", and "first A" can be interpreted as A pre-specified in a protocol, etc., or as A obtained through setting, configuration, or indication, etc., or as specific A, a certain A, any A, or first A, etc., but not limited to this.

[0286] In some embodiments, the determination or judgment can be performed by a value represented by 1 bit (0 or 1), or by a true or false value (Boolean value) represented by true or false, or by comparison of numerical values ​​(for example, comparison with a predetermined value), but is not limited thereto.

[0287] In some embodiments, "not expecting to receive" can be interpreted as not receiving on time domain resources and / or frequency domain resources, or as not performing subsequent processing on the data after receiving it; "not expecting to send" can be interpreted as not sending, or as sending but not expecting the recipient to respond to the content sent.

[0288] The communication method involved in the embodiments of the present disclosure may include at least one of steps S3101 to S3103. For example, step S3101 can be implemented as an independent embodiment, step S3102 can be implemented as an independent embodiment, steps 1+3 can be implemented as an independent embodiment, steps S3101+S3102 can be implemented as an independent embodiment, and steps S3102+S3103 can be implemented as an independent embodiment, but the present invention is not limited thereto.

[0289] In some embodiments, steps S3102 and S3103 may be performed simultaneously.

[0290] In some embodiments, steps S3102 and S3103 are optional, and one or more of these steps may be omitted or replaced in different embodiments.

[0291] In some embodiments, steps S3101 and S3103 are optional, and one or more of these steps may be omitted or replaced in different embodiments.

[0292] In some embodiments, reference may be made to other optional implementations described before or after the description corresponding to FIG. 3 .

[0293] According to the solution provided by the embodiment of the present disclosure, the first communication device can configure the uplink resources for the Ambient IOT device to send the first command response in the following manner.

[0294] Method 1: When the first communication device sends a first command message to one or more Ambient IoT devices, the first communication device instructs the one or more Ambient IoT devices to send uplink frequency domain resources in response to the first command.

[0295] Optionally, the first command message includes but is not limited to Query, ACK, Read, Write and other signaling.

[0296] Optionally, the uplink frequency domain resource may be an uplink subchannel, subcarrier, etc.

[0297] Optionally, the first communication device may indicate the subchannel or subcarrier allocated to the Ambient IoT device by indicating a channel index.

[0298] The uplink frequency domain resource may be a device-specific frequency domain resource or a command-specific frequency domain resource. In addition, the uplink frequency domain resource may be an uplink frequency domain resource set.

[0299] Optionally, the Ambient IoT device may send a first command response in a device-specific uplink frequency domain resource set.

[0300] Alternatively, the Ambient IOT device may randomly select an uplink frequency domain resource from the command-specific uplink frequency domain resource set, and send the first command response on the selected uplink frequency domain resource.

[0301] For example, the Ambient IOT device can use the temporary identity or ID of the Ambient IOT device to perform a modulo operation on the number of channels included in the uplink frequency domain resource set to obtain the corresponding channel number, thereby sending a first command response on the channel indicated by the channel number.

[0302] Method 2: When the first communication device sends the first command message to one or more Ambient IoT devices, the first communication device instructs the one or more Ambient IoT devices to send an uplink time domain resource or an uplink time domain resource range for the first command response.

[0303] Optionally, the first communication device may indicate the time (ie, the first time) elapsed from when the one or more Ambient IOT devices receive the first command message to when they send the first command response.

[0304] Optionally, the first time may be determined by the first communication device according to a message size or message type of the first command message; or, the first time may be determined by the first communication device according to an expected message size or expected message type of the first command response.

[0305] Optionally, the first time may be a fixed value or a range value.

[0306] Optionally, for the Ambient IoT device, if the Ambient IoT device receives the first command message, it may send a first command response a first time after receiving the first command message according to an instruction carried in the first command message.

[0307] Optionally, the first communication device may indicate corresponding first times to one or more Ambient IoT devices respectively, and the time interval between any two first times is greater than or equal to a first threshold.

[0308] Optionally, the first communication device may further indicate a time at which the Ambient IoT device stops sending command responses.

[0309] Method three: When the first communication device sends a first command message to one or more Ambient IOT devices, it indicates first parameter information (similar to the Q value in the Query signaling). The first parameter information is used for one or more Ambient IOT devices to generate second parameter information. The second parameter information can be a value generated based on the first parameter information. The second parameter information generated by different Ambient IOT devices may be different (randomly generated or generated based on specific rules). The Ambient IOT device can determine the timing of sending the first command response based on the second parameter information to reduce or avoid uplink resource conflicts between different Ambient IOT devices.

[0310] Optionally, the first communication device sends a first command message to the Ambient IOT device, and the Ambient IOT device receives the first command message, the first command message indicating first parameter information, and the Ambient IOT device can generate a random number based on the first parameter information. After sending the first command message, the first communication device can repeatedly send the first command message, or send a second command message (similar to QueryRep signaling). The Ambient IOT device can determine whether the currently received command message and the previously received command message are for the same command based on the indication in the command message (including the first command message and the second command message) or the content of the command message. Each time the Ambient IOT device receives a command message for the same command, it can reduce the value of the random number. When the value of the random number is reduced to 0 or a specific value, the Ambient IOT can send a first command response to the first communication device.

[0311] Optionally, the random number may be generated randomly; or, the random number may be generated according to specific rules. For example, according to the priority of the transmitted content or the priority itself, different priorities may correspond to different ranges of values, and the Ambient IOT device may generate a random number within the range of values ​​corresponding to the priority.

[0312] Optionally, the first communication device sends a first command message to the Ambient IOT device, and the Ambient IOT device receives the first command message. The first command message indicates first parameter information. The Ambient IOT can generate a timer value based on the first parameter information and start the timer. When the timer expires, the Ambient IOT device can send a first command response to the first communication device.

[0313] Optionally, the timer value may be randomly generated; or, the timer value may be generated according to specific rules. For example, different priorities may correspond to different ranges of values ​​based on the priority of the transmitted content or the priority itself. The Ambient IOT device may generate the timer value within the range of values ​​corresponding to the priority.

[0314] It should be noted that the above three methods can be configured independently or simultaneously. For example, the first communication device can configure specific frequency domain resources and specific time domain resources (range), and the Ambient IOT device sends a first command response on the configured resources. For another example, the Ambient IOT device sends a first command response on a specific frequency domain resource and / or a specific time domain resource (range) based on method three.

[0315] Optionally, the first command message may include at least one of the following:

[0316] Commands used to request Ambient IoT devices to send device codes (such as EPC and RN16), such as ACK signaling and Random Number Request (Req_RN) signaling;

[0317] Commands used to instruct Ambient IoT devices to perform subsequent operations, such as Write signaling, Read signaling, Lock signaling, and Kill signaling.
