[0227] 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.

[0228] 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.

[0229] 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).

[0230] In some embodiments, wireless communication design of ambient IoT devices can be implemented based on backscatter technology.

[0231] 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.

[0232] 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.

[0233] In some embodiments, ambient IoT devices can be divided into two types: type 1 and type 2.

[0234] 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.

[0235] 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.

[0236] Optionally, whether it is a type 1 Ambient IOT device or a type 2 Ambient IOT device, there may be multiple network access methods.

[0237] 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.

[0238] 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.

[0239] 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.

[0240] FIG3A is an interactive diagram of a communication method according to an embodiment of the present disclosure. As shown in FIG3A , the embodiment of the present disclosure relates to a communication method, and the method includes:

[0241] Step S3101: The first communication device determines first information based on a first delay requirement.

[0242] In some embodiments, the first communication device is an intermediate node (including but not limited to a relay, an IAB node, a UE, a repeater), or the first communication device is an access network device, or the first communication device is a core network device (such as a core network function node), or the first communication device is an Ambient IOT server, but not limited to this. For an introduction to the first communication device, please refer to the embodiment corresponding to Figure 1, which will not be repeated here.

[0243] In some embodiments, the terms "access network (AN)", "radio", "wireless", "radio access network (RAN)", "RAN-based" and the like can be used interchangeably.

[0244] Taking the network architecture shown in Figure 2A as an example, the first communication device can be a base station, but is not limited to this. The first communication device can also be a core network device or a core network functional node, or the first communication device is an Ambient IOT server; taking the network architecture shown in Figure 2B as an example, the first communication device can be a base station, or the first communication device can be an intermediate node, but is not limited to this. The first communication device can also be a core network device or a core network functional node, or the first communication device is an Ambient IOT server.

[0245] In some embodiments, the first latency requirement is an expected transmission latency from the Ambient IoT device to the third communication device.

[0246] Optionally, the first communication device is an intermediate node, and the third communication device is any one of an intermediate node, an access network device, a core network device, and an Ambient IOT server; the first communication device is an access network device, and the third communication device is any one of an intermediate node, an access network device, a core network device, and an Ambient IOT server; the first communication device is a core network device, and the third communication device is any one of an intermediate node, an access network device, a core network device, and an Ambient IOT server; the first communication device is an Ambient IOT server, and the third communication device is any one of an intermediate node, an access network device, a core network device, and an Ambient IOT server.

[0247] Taking the network architecture shown in Figure 2A as an example, the first delay requirement can be the expected transmission delay from the Ambient IOT device to the access network device, or the first delay requirement can be the expected transmission delay from the Ambient IOT device to the core network device, or the first delay requirement can be the expected transmission delay from the Ambient IOT device to the Ambient IOT server.

[0248] Taking the network architecture shown in Figure 2B as an example, the first delay requirement can be the expected transmission delay from the Ambient IOT device to the intermediate node, or the first delay requirement can be the expected transmission delay from the Ambient IOT device to the access network device, or the first delay requirement can be the expected transmission delay from the Ambient IOT device to the core network device, or the first delay requirement can be the expected transmission delay from the Ambient IOT device to the Ambient IOT server.

[0249] It should be noted that the transmission delay from the access network device to the core network device and from the core network device to the Ambient IOT server can be controllable.

[0250] In some embodiments, the first delay requirement may be configured by the fourth communication device for the first communication device.

[0251] Optionally, the first communication device is an intermediate node, and the fourth communication device is any one of an access network device, a core network device, and an Ambient IOT server; the first communication device is an access network device, and the fourth communication device is a core network device or an Ambient IOT server; the first communication device is a core network device, and the fourth communication device is an access network device or an Ambient IOT server; the first communication device is an Ambient IOT server, and the fourth communication device is an access network device or a core network device.

[0252] In some embodiments, the fourth communication device may configure the first delay requirement for the first communication device according to task requirements.

[0253] For example, the Ambient IOT server may determine a corresponding delay requirement according to the task type of the inventory task, and thereby configure the determined delay requirement as the first delay requirement to the first communication device.

[0254] In some embodiments, the fourth communication device may send the first delay requirement to the first communication device, and the first communication device may receive the first delay requirement sent by the fourth communication device, so as to achieve the purpose of configuring the first delay requirement for the first communication device by the fourth communication device.

[0255] In some embodiments, the first latency requirement may be agreed upon in a protocol. For example, the protocol may agree that the expected transmission latency indicated by the first latency requirement is {1s, 10s}, where 1 second (s) is the expected short latency target and 10s is the expected long latency target. The first latency requirement agreed upon in the protocol may also have other values, which are not limited here.

[0256] Optionally, the first communication device can directly obtain the first delay requirement agreed upon in the protocol; or, the fourth communication device can obtain the first delay requirement agreed upon in the protocol, and then send the obtained first delay requirement to the first communication device, so that the first communication device can obtain the first delay requirement agreed upon in the protocol.

[0257] In some embodiments, an ambient IoT device communicates with a third communication device via another device, and a first latency requirement can be divided into multiple second latency requirements. Each second latency requirement indicates the expected transmission latency between two devices on a first communication link between the ambient IoT device and the third communication device.

[0258] That is, when the first communication link corresponding to the Ambient IOT device and the third communication device is segmented, the first delay requirement can be divided into multiple second delay requirements, and the transmission delay between every two devices on the first communication link can correspond to one delay requirement.

[0259] Optionally, the two devices may be two adjacent devices on the first communication link, or the two devices may be separated by a first number of devices on the first communication link, where the first number may be any value.

[0260] For example, if the first communication link is "Ambient IOT device → intermediate node → access network device → core network device → Ambient IOT server", then the multiple second delay requirements may include the transmission delay from the Ambient IOT device to the intermediate node, the transmission delay from the intermediate node to the access network device, the transmission delay from the access network device to the core network device, and the transmission delay from the core network device to the Ambient IOT server, but are not limited to this. Since the transmission delay from the access network device to the core network device and then to the base station is controllable, the multiple second delay requirements may also include the transmission delay from the Ambient IOT device to the intermediate node, the transmission delay from the intermediate node to the access network device, and the transmission delay from the access network device to the Ambient IOT server.

[0261] The process of dividing the first delay requirement may be performed by the fourth communication device, or the process of dividing the first delay requirement may be performed by the first communication device.

[0262] For example, the third communication device is an access network device, and the Ambient IOT device communicates with the access network device through an intermediate node. That is, the first communication link is "Ambient IOT device → intermediate node → access network device". The fourth communication device can divide the first delay requirement into two second delay requirements, one of which is the expected transmission delay from the Ambient IOT device to the intermediate node, and the other is the expected transmission delay from the intermediate node to the access network device. Thus, the second delay requirement indicating the expected transmission delay from the Ambient IOT device to the intermediate node can be sent to the intermediate node, and the second delay requirement indicating the expected transmission delay from the intermediate node to the access network device can be sent to the access network device. The intermediate node and the access network device respectively control the transmission delay of these two transmission paths.

[0263] Alternatively, the first communication device and the third communication device are both access network devices, and the Ambient IOT device communicates with the access network device through an intermediate node. That is, the first communication link is "Ambient IOT device→intermediate node→access network device". The first communication device can divide the first delay requirement into two second delay requirements, one of which is the expected transmission delay from the Ambient IOT device to the intermediate node, and the other is the expected transmission delay from the intermediate node to the access network device. Thus, the second delay requirement indicating the expected transmission delay from the Ambient IOT device to the intermediate node can be sent to the intermediate node, and the intermediate node can perform delay control based on the expected transmission delay from the Ambient IOT device to the intermediate node, and the access network device can perform delay control based on the expected transmission delay from the intermediate node to the access network device.

[0264] Alternatively, the first communication device is an intermediate node, the third communication device is an access network device, and the Ambient IOT device communicates with the access network device through the intermediate node, that is, the first communication link is "Ambient IOT device→intermediate node→access network device", the first communication device can divide the first delay requirement into two second delay requirements, one of the second delay requirements is the expected transmission delay from the Ambient IOT device to the intermediate node, and the other second delay requirement is the expected transmission delay from the intermediate node to the access network device. The intermediate node can perform delay control based on the expected transmission delay from the Ambient IOT device to the intermediate node, and the intermediate node can send the second delay requirement indicating the expected transmission delay from the intermediate node to the access network device to the access network device, and the access network device will perform delay control based on the expected transmission delay from the Ambient IOT device to the intermediate node.

[0265] For another example, the third communication device is an Ambient IOT server, and the Ambient IOT device communicates with the Ambient IOT server through an intermediate node, an access network device, and a core network device, that is, the first communication link is "Ambient IOT device → intermediate node → access network device → core network device → Ambient IOT server", and the fourth communication device can divide the first delay requirement into three second delay requirements, one of which is the expected transmission delay from the Ambient IOT device to the intermediate node, one is the expected transmission delay from the intermediate node to the access network device, and the other is the expected transmission delay from the access network device to the core network device and then to the Ambient IOT server. Since the transmission delay from the access network device to the core network device and then to the Ambient IOT server can be controllable, the fourth communication device can indicate from the Ambient IOT device to the intermediate node. The second delay requirement indicating the expected transmission delay from the IoT device to the intermediate node is sent to the intermediate node, and the second delay requirement indicating the expected transmission delay from the intermediate node to the access network device is sent to the access network device. The intermediate node and the access network device respectively control the transmission delay of these two transmission paths.

[0266] Alternatively, the first communication device is an access network device, the third communication device is an Ambient IOT server, and the Ambient IOT device communicates with the Ambient IOT server through an intermediate node, an access network device, and a core network device. That is, the first communication link is "Ambient IOT device → intermediate node → access network device → core network device → Ambient IOT server". The first communication device can divide the first delay requirement into three second delay requirements, one of which is the expected transmission delay from the Ambient IOT device to the intermediate node, one is the expected transmission delay from the intermediate node to the access network device, and the other is the expected transmission delay from the access network device to the core network device and then to the Ambient IOT server. Since the transmission delay from the access network device to the core network device and then to the Ambient IOT server can be controllable, the access network device can send the second delay requirement indicating the expected transmission delay from the Ambient IOT device to the intermediate node to the intermediate node, and the intermediate node calculates the second delay requirement based on the transmission delay from the Ambient IOT device to the intermediate node. The delay control is performed based on the expected transmission delay from the IoT device to the intermediate node, while the access network device can perform delay control based on the expected transmission delay from the intermediate node to the access network device.

[0267] Alternatively, the first communication device is an intermediate node, the third communication device is an Ambient IOT server, and the Ambient IOT device communicates with the Ambient IOT server through the intermediate node, the access network device and the core network device, that is, the first communication link is "Ambient IOT device → intermediate node → access network device → core network device → Ambient IOT server", the first communication device can divide the first delay requirement into three second delay requirements, one of which is the expected transmission delay from the Ambient IOT device to the intermediate node, one is the expected transmission delay from the intermediate node to the access network device, and the other is the expected transmission delay from the access network device to the core network device and then to the Ambient IOT server. Since the transmission delay from the access network device to the core network device and then to the Ambient IOT server can be controllable, the intermediate node can adjust the transmission delay according to the transmission delay from the Ambient IOT device to the core network device. The expected transmission delay from the IoT device to the intermediate node is subjected to delay control, and the intermediate node can send a second delay requirement indicating the expected transmission delay from the intermediate node to the access network device to the access network device, and the access network device performs delay control based on the expected transmission delay from the ambient IoT device to the intermediate node.

[0268] The above are only a few exemplary ways of dividing and allocating delay requirements and do not constitute a limitation on the embodiments of the present disclosure.

[0269] In some embodiments, the first delay requirement may be a one-way transmission delay or a round-trip transmission delay.

[0270] In some embodiments, the first delay requirement is the round-trip transmission delay, and the first delay requirement can be divided into a third delay requirement and a fourth delay requirement. The third delay requirement is the forward transmission delay (or uplink transmission delay), and the fourth delay requirement is the return transmission delay (or downlink transmission delay).

[0271] In some embodiments, terms such as "uplink", "uplink", "physical uplink" can be interchangeable with each other, and terms such as "downlink", "downlink", "physical downlink" can be interchangeable with each other, and terms such as "side", "sidelink", "side communication", "sidelink communication", "direct connection", "direct link", "direct communication", "direct link communication" can be interchangeable with each other.

[0272] Optionally, before the fourth communication device configures the first delay requirement for the first communication device, the fourth communication device can determine whether the first delay requirement is a round-trip delay requirement. If so, the fourth communication device can divide the first delay requirement to obtain the desired forward transmission delay and return transmission delay.

[0273] Alternatively, the first communication device may determine whether the first delay requirement is a round-trip delay requirement after obtaining the first delay requirement agreed upon in the protocol, or after receiving the first delay requirement configured by the fourth communication device. If so, the first communication device may divide the first delay requirement to obtain the desired forward transmission delay and return transmission delay.

[0274] In some embodiments, whether the first delay requirement is divided into segments or the expected forward transmission delay and return transmission delay of the first delay requirement are divided, the division of the delay requirement can be implemented based on a pre-set division strategy or according to a division method determined by dynamic scheduling.

[0275] In some embodiments, the first communication device can determine the transmission delay when the Ambient IOT device sends data to the second communication device based on the first delay requirement (that is, the expected transmission delay from the Ambient IOT device to the third communication device) to achieve determination of the first information.

[0276] Optionally, the first communication device is an intermediate node, and the second communication device is any one of an intermediate node, an access network device, a core network device, and an Ambient IOT server; the first communication device is an access network device, and the second communication device is any one of an intermediate node, an access network device, a core network device, and an Ambient IOT server; the first communication device is a core network device, and the second communication device is any one of an intermediate node, an access network device, a core network device, and an Ambient IOT server; the first communication device is an Ambient IOT server, and the second communication device is any one of an intermediate node, an access network device, a core network device, and an Ambient IOT server.

[0277] In some embodiments, the first delay requirement corresponds to multiple transmission paths, and corresponding information can be determined based on multiple second delay requirements obtained by dividing the first delay requirement, where the first information can correspond to the transmission path from the Ambient IoT device to its next node on the first communication link.

[0278] In some embodiments, the first information may be used to indicate a transmission delay from the Ambient IoT device to its next node on the first communication link.

[0279] In some embodiments, the name of the first latency requirement is not limited, and may be, for example, "latency target", "latency definition", etc.

[0280] In some embodiments, the name of the first information is not limited, and it can be, for example, "target delay information", "delay indication information", etc.

[0281] 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.

[0282] Step S3102: The first communication device sends first information to the Ambient IoT device.

[0283] In some embodiments, the first communication device is an access network device, and the access network device can directly communicate with the Ambient IOT device, then the first communication device can directly send the first information to the Ambient IOT device.

[0284] In some embodiments, the first communication device is an access network device, and the access network device communicates with the Ambient IOT device through an intermediate node. The first communication device can send the first information to the intermediate node, and the intermediate node sends the first information to the Ambient IOT device.

[0285] In some embodiments, the first communication device is an intermediate node, and the intermediate node can directly communicate with the Ambient IoT device. In this case, the first communication device can directly send the first information to the Ambient IoT device.

[0286] In some embodiments, the ambient IoT device receives first information sent by the first communication device.

[0287] In more possible implementations, step S3101 and step S3102 may be optional, that is, the Ambient IoT device may obtain the first information through an implementation method different from step S3101 and step S3102, such as the Ambient IoT device may obtain the first information agreed upon in the protocol.

[0288] Optionally, after obtaining the first information agreed upon in the protocol, the Ambient IoT device may directly execute step S3103 to implement data transmission based on the first information.

[0289] Optionally, after obtaining the first information agreed upon in the protocol, the Ambient IOT device can divide the first information, including but not limited to the division into multiple transmission paths and the division into round-trip transmission delays, so as to send data based on the results obtained by dividing the first information. The process of dividing the first information is the same as the process of dividing the first delay requirement, and will not be repeated here.

[0290] Step S3103: The Ambient IoT device sends first data to the second communication device based on the first information.

[0291] The first information is used to indicate the expected transmission delay of the Ambient IoT device for sending data.

[0292] In some embodiments, the Ambient IoT device may send the first data within the time indicated by the first information, thereby controlling the transmission delay.

[0293] The first data is data of the Ambient IOT device, including but not limited to data collected by the Ambient IOT device, some data stored by the Ambient IOT device itself, and the like.

[0294] Optionally, methods of controlling transmission delay include but are not limited to selecting a suitable communication protocol, adjusting transmission parameters, using scheduling and queuing algorithms, setting a data transmission order according to priority, and the like.

[0295] In some embodiments, an Ambient IOT device is any tag device that sends data.

[0296] For example, the Ambient IOT device is the first, last, or any tag device that sends data.

[0297] 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.

[0298] In some embodiments, terms such as "send", "transmit", "report", "download", "transmit", "bidirectional transmission", "send and / or receive" can be used interchangeably.

[0299] In some embodiments, terms such as "certain", "preset", "preset", "setting", "indicated", "some", "any", and "first" can be interchangeable. "Specific A", "preset A", "preset A", "setting A", "indicated A", "some 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, some A, any A, or first A, etc., but not limited to this.

[0300] 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.

[0301] 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.

[0306] FIG3B is an interactive diagram of a communication method according to an embodiment of the present disclosure. As shown in FIG3B , the embodiment of the present disclosure relates to a communication method, and the method includes:

[0307] Step S3201: The first communication device sends an uplink resource that meets the first delay requirement to the Ambient IoT device based on the first delay requirement.

[0308] In some embodiments, the first communication device is an intermediate node (including but not limited to a relay, an IAB node, a UE, a repeater), or the first communication device is an access network device, or the first communication device is a core network device (such as a core network function node), or the first communication device is an Ambient IOT server, but not limited to this. For an introduction to the first communication device, please refer to the embodiment corresponding to Figure 1, which will not be repeated here.

[0309] Taking the network architecture shown in Figure 2A as an example, the first communication device can be a base station, but is not limited to this. The first communication device can also be a core network device or a core network functional node, or the first communication device is an Ambient IOT server; taking the network architecture shown in Figure 2B as an example, the first communication device can be a base station, or the first communication device can be an intermediate node, but is not limited to this. The first communication device can also be a core network device or a core network functional node, or the first communication device is an Ambient IOT server.

[0310] In some embodiments, the first latency requirement is an expected transmission latency from the Ambient IoT device to the third communication device.

[0311] Optionally, the first communication device is an intermediate node, and the third communication device is any one of an intermediate node, an access network device, a core network device, and an Ambient IOT server; the first communication device is an access network device, and the third communication device is any one of an intermediate node, an access network device, a core network device, and an Ambient IOT server; the first communication device is a core network device, and the third communication device is any one of an intermediate node, an access network device, a core network device, and an Ambient IOT server; the first communication device is an Ambient IOT server, and the third communication device is any one of an intermediate node, an access network device, a core network device, and an Ambient IOT server.

[0312] Taking the network architecture shown in Figure 2A as an example, the first delay requirement can be the expected transmission delay from the Ambient IOT device to the access network device, or the first delay requirement can be the expected transmission delay from the Ambient IOT device to the core network device, or the first delay requirement can be the expected transmission delay from the Ambient IOT device to the Ambient IOT server.

[0313] Taking the network architecture shown in Figure 2B as an example, the first delay requirement can be the expected transmission delay from the Ambient IOT device to the intermediate node, or the first delay requirement can be the expected transmission delay from the Ambient IOT device to the access network device, or the first delay requirement can be the expected transmission delay from the Ambient IOT device to the core network device, or the first delay requirement can be the expected transmission delay from the Ambient IOT device to the Ambient IOT server.

[0314] It should be noted that the transmission delay from the access network device to the core network device and from the core network device to the Ambient IOT server can be controllable.

[0315] In some embodiments, the first delay requirement may be configured by the fourth communication device for the first communication device.

[0316] Optionally, the first communication device is an intermediate node, and the fourth communication device is any one of an access network device, a core network device, and an Ambient IOT server; the first communication device is an access network device, and the fourth communication device is a core network device or an Ambient IOT server; the first communication device is a core network device, and the fourth communication device is an access network device or an Ambient IOT server; the first communication device is an Ambient IOT server, and the fourth communication device is an access network device or a core network device.

[0317] In some embodiments, the fourth communication device may configure the first delay requirement for the first communication device according to task requirements.

[0318] For example, the Ambient IOT server may determine a corresponding delay requirement according to the task type of the inventory task, and thereby configure the determined delay requirement as the first delay requirement to the first communication device.

[0319] In some embodiments, the fourth communication device may send the first delay requirement to the first communication device, and the first communication device may receive the first delay requirement sent by the fourth communication device, so as to achieve the purpose of configuring the first delay requirement for the first communication device by the fourth communication device.

[0320] In some embodiments, the first latency requirement may be agreed upon in a protocol. For example, the protocol may agree that the expected transmission latency indicated by the first latency requirement is {1s, 10s}, where 1 second (s) is the expected short latency target and 10s is the expected long latency target. The first latency requirement agreed upon in the protocol may also have other values, which are not limited here.

[0321] Optionally, the first communication device can directly obtain the first delay requirement agreed upon in the protocol; or, the fourth communication device can obtain the first delay requirement agreed upon in the protocol, and then send the obtained first delay requirement to the first communication device, so that the first communication device can obtain the first delay requirement agreed upon in the protocol.

[0322] In some embodiments, an ambient IoT device communicates with a third communication device via another device, and a first latency requirement can be divided into multiple second latency requirements. Each second latency requirement indicates the expected transmission latency between two devices on a first communication link between the ambient IoT device and the third communication device.

[0323] That is, when the first communication link corresponding to the Ambient IOT device and the third communication device is segmented, the first delay requirement can be divided into multiple second delay requirements, and the transmission delay between every two devices on the first communication link can correspond to one delay requirement.

[0324] Optionally, the two devices may be two adjacent devices on the first communication link, or the two devices may be separated by a first number of devices on the first communication link, where the first number may be any value.

[0325] For example, if the first communication link is "Ambient IOT device → intermediate node → access network device → core network device → Ambient IOT server", then the multiple second delay requirements may include the transmission delay from the Ambient IOT device to the intermediate node, the transmission delay from the intermediate node to the access network device, the transmission delay from the access network device to the core network device, and the transmission delay from the core network device to the Ambient IOT server, but are not limited to this. Since the transmission delay from the access network device to the core network device and then to the base station is controllable, the multiple second delay requirements may also include the transmission delay from the Ambient IOT device to the intermediate node, the transmission delay from the intermediate node to the access network device, and the transmission delay from the access network device to the Ambient IOT server.

[0326] The process of dividing the first delay requirement may be performed by the fourth communication device, or the process of dividing the first delay requirement may be performed by the first communication device.

[0327] For example, the third communication device is an access network device, and the Ambient IOT device communicates with the access network device through an intermediate node. That is, the first communication link is "Ambient IOT device → intermediate node → access network device". The fourth communication device can divide the first delay requirement into two second delay requirements, one of which is the expected transmission delay from the Ambient IOT device to the intermediate node, and the other is the expected transmission delay from the intermediate node to the access network device. Thus, the second delay requirement indicating the expected transmission delay from the Ambient IOT device to the intermediate node can be sent to the intermediate node, and the second delay requirement indicating the expected transmission delay from the intermediate node to the access network device can be sent to the access network device. The intermediate node and the access network device respectively control the transmission delay of these two transmission paths.

[0328] Alternatively, the first communication device and the third communication device are both access network devices, and the Ambient IOT device communicates with the access network device through an intermediate node. That is, the first communication link is "Ambient IOT device→intermediate node→access network device". The first communication device can divide the first delay requirement into two second delay requirements, one of which is the expected transmission delay from the Ambient IOT device to the intermediate node, and the other is the expected transmission delay from the intermediate node to the access network device. Thus, the second delay requirement indicating the expected transmission delay from the Ambient IOT device to the intermediate node can be sent to the intermediate node, and the intermediate node can perform delay control based on the expected transmission delay from the Ambient IOT device to the intermediate node, and the access network device can perform delay control based on the expected transmission delay from the intermediate node to the access network device.

[0329] Alternatively, the first communication device is an intermediate node, the third communication device is an access network device, and the Ambient IOT device communicates with the access network device through the intermediate node, that is, the first communication link is "Ambient IOT device→intermediate node→access network device", the first communication device can divide the first delay requirement into two second delay requirements, one of the second delay requirements is the expected transmission delay from the Ambient IOT device to the intermediate node, and the other second delay requirement is the expected transmission delay from the intermediate node to the access network device. The intermediate node can perform delay control based on the expected transmission delay from the Ambient IOT device to the intermediate node, and the intermediate node can send the second delay requirement indicating the expected transmission delay from the intermediate node to the access network device to the access network device, and the access network device will perform delay control based on the expected transmission delay from the Ambient IOT device to the intermediate node.

[0330] For another example, the third communication device is an Ambient IOT server, and the Ambient IOT device communicates with the Ambient IOT server through an intermediate node, an access network device, and a core network device, that is, the first communication link is "Ambient IOT device → intermediate node → access network device → core network device → Ambient IOT server", and the fourth communication device can divide the first delay requirement into three second delay requirements, one of which is the expected transmission delay from the Ambient IOT device to the intermediate node, one is the expected transmission delay from the intermediate node to the access network device, and the other is the expected transmission delay from the access network device to the core network device and then to the Ambient IOT server. Since the transmission delay from the access network device to the core network device and then to the Ambient IOT server can be controllable, the fourth communication device can indicate from the Ambient IOT device to the intermediate node. The second delay requirement indicating the expected transmission delay from the IoT device to the intermediate node is sent to the intermediate node, and the second delay requirement indicating the expected transmission delay from the intermediate node to the access network device is sent to the access network device. The intermediate node and the access network device respectively control the transmission delay of these two transmission paths.

[0331] Alternatively, the first communication device is an access network device, the third communication device is an Ambient IOT server, and the Ambient IOT device communicates with the Ambient IOT server through an intermediate node, an access network device, and a core network device. That is, the first communication link is "Ambient IOT device → intermediate node → access network device → core network device → Ambient IOT server". The first communication device can divide the first delay requirement into three second delay requirements, one of which is the expected transmission delay from the Ambient IOT device to the intermediate node, one is the expected transmission delay from the intermediate node to the access network device, and the other is the expected transmission delay from the access network device to the core network device and then to the Ambient IOT server. Since the transmission delay from the access network device to the core network device and then to the Ambient IOT server can be controllable, the access network device can send the second delay requirement indicating the expected transmission delay from the Ambient IOT device to the intermediate node to the intermediate node, and the intermediate node calculates the second delay requirement based on the transmission delay from the Ambient IOT device to the intermediate node. The delay control is performed based on the expected transmission delay from the IoT device to the intermediate node, while the access network device can perform delay control based on the expected transmission delay from the intermediate node to the access network device.

[0332] Alternatively, the first communication device is an intermediate node, the third communication device is an Ambient IOT server, and the Ambient IOT device communicates with the Ambient IOT server through the intermediate node, the access network device and the core network device, that is, the first communication link is "Ambient IOT device → intermediate node → access network device → core network device → Ambient IOT server", the first communication device can divide the first delay requirement into three second delay requirements, one of which is the expected transmission delay from the Ambient IOT device to the intermediate node, one is the expected transmission delay from the intermediate node to the access network device, and the other is the expected transmission delay from the access network device to the core network device and then to the Ambient IOT server. Since the transmission delay from the access network device to the core network device and then to the Ambient IOT server can be controllable, the intermediate node can adjust the transmission delay according to the transmission delay from the Ambient IOT device to the core network device. The expected transmission delay from the IoT device to the intermediate node is subjected to delay control, and the intermediate node can send a second delay requirement indicating the expected transmission delay from the intermediate node to the access network device to the access network device, and the access network device performs delay control based on the expected transmission delay from the ambient IoT device to the intermediate node.

[0333] The above are only a few exemplary ways of dividing and allocating delay requirements and do not constitute a limitation on the embodiments of the present disclosure.

[0334] In some embodiments, the expected transmission delay indicated by the first delay requirement may be a one-way transmission delay or a round-trip transmission delay.

[0335] In some embodiments, the first delay requirement is the round-trip transmission delay, and the first delay requirement can be divided into a third delay requirement and a fourth delay requirement. The third delay requirement is the forward transmission delay (or uplink transmission delay), and the fourth delay requirement is the return transmission delay (or downlink transmission delay).

[0336] Optionally, before the fourth communication device configures the first delay requirement for the first communication device, the fourth communication device can determine whether the first delay requirement is a round-trip delay requirement. If so, the fourth communication device can divide the first delay requirement to obtain the desired forward transmission delay and return transmission delay.

[0337] Alternatively, the first communication device may determine whether the first delay requirement is a round-trip delay requirement after obtaining the first delay requirement agreed upon in the protocol, or after receiving the first delay requirement configured by the fourth communication device. If so, the first communication device may divide the first delay requirement to obtain the desired forward transmission delay and return transmission delay.

[0338] In some embodiments, whether the first delay requirement is divided into segments or the expected forward transmission delay and return transmission delay of the first delay requirement are divided, the division of the delay requirement can be implemented based on a pre-set division strategy or according to a division method determined by dynamic scheduling.

[0339] In some embodiments, the first communication device may configure uplink resources that meet the first delay requirement for the Ambient IOT device based on the first delay requirement (ie, the expected transmission delay from the Ambient IOT device to the third communication device).

[0340] In some embodiments, the first communication device is an access network device, and the access network device can communicate directly with the Ambient IOT device. The first communication device can directly send uplink resources that meet the first latency requirement to the Ambient IOT device.

[0341] In some embodiments, the first communication device is an access network device, and the access network device communicates with the Ambient IOT device through an intermediate node. The first communication device can send relevant configuration information of the uplink resources that meet the first delay requirement to the intermediate node, and the intermediate node will send the uplink resources that meet the first delay requirement to the Ambient IOT device.

[0342] In some embodiments, the first communication device is an intermediate node, and the intermediate node can directly communicate with the Ambient IoT device. In this case, the first communication device can directly send the uplink resources that meet the first latency requirement to the Ambient IoT device.

[0343] In some embodiments, the ambient IoT device receives uplink resources sent by the first communication device.

[0344] In some embodiments, the name of the first latency requirement is not limited, and may be, for example, "latency target", "latency definition", etc.

[0345] Step S3202: The ambient IoT device sends first data to the second communication device on an uplink resource that meets a first latency requirement.

[0347] The first data is data of an Ambient IOT device.

[0348] The transmission delay of the first data is ensured by sending the first data on an uplink resource that meets the first delay requirement.

[0349] The first data is data of the Ambient IOT device, including but not limited to data collected by the Ambient IOT device, some data stored by the Ambient IOT device itself, and the like.

[0434] It should be noted that the implementation of each step in FIG4D can refer to the implementation of the corresponding steps in FIG3A and FIG3B , and will not be repeated here.

[0435] In some embodiments, step S4304 and step S4305 may be executed in an interchanged order or simultaneously.

[0436] The above embodiment only takes the first communication device as an intermediate node or base station as an example to illustrate the communication method provided in the embodiment of the present disclosure, and does not constitute a limitation of the embodiment of the present disclosure. In more possible implementation methods, the first communication device can also be a core network device or an Ambient IOT server.

[0437] According to the solution provided by the embodiments of the present disclosure, there are two network topologies:

[0438] Network topology 1: Ambient IoT device → intermediate node → base station → … → Ambient IoT server;

[0439] Network topology 2: Ambient IoT device → intermediate node → base station → … → Ambient IoT server.

[0440] In some embodiments, one-way end-to-end latency can be understood as the transmission latency from the Ambient IoT device to the Ambient IoT server. Since the transmission latency from the access network device to the Ambient IoT server is controllable, the first latency requirement of the RAN design can be:

[0441] (1) The transmission delay from the tag (that is, the ambient IoT device) to the reader, that is, the transmission delay from the ambient IoT device to the base station in network topology 1, and the transmission delay from the ambient IoT device to the intermediate node in network topology 2.

[0442] (2) Transmission delay from the tag (also known as the ambient IoT device) to the base station.

[0443] Among them, the Ambient IoT device can be the first, last, or any tag that sends data.

[0444] Optionally, the first delay requirement can be understood as the round-trip transmission delay (DL+UL). Additionally, the fourth communication device (ie, the network device or the Ambient IOT server) can divide the one-way delay during the implementation process and control the uplink and downlink transmission delays separately.

[0445] Optionally, the segmentation may be performed based on a policy or dynamic scheduling.

[0446] Optionally, the first delay requirement may be agreed upon by the protocol (for example, typically {1s, 10s}); or, the first delay requirement may be flexibly configured to the delay control node on demand (for example, the Ambient IOT server determines the corresponding delay requirement based on the inventory task and configures it).

[0447] Optionally, in network topology 1, the BS may serve as the first communication device; in network topology 2, the first communication device may be at least one of a BS and an intermediate node (such as a UE).

[0448] Optionally, if the first delay requirement is the transmission delay from the Ambient IOT device to the BS, the BS can perform delay requirement segmentation (segmentation based on policy implementation or dynamic scheduling) to determine the transmission delay from the Ambient IOT device to the intermediate node, and the transmission delay from the intermediate node to the BS. The BS can perform delay control based on the transmission delay from the intermediate node to the BS, and send the delay requirement from the Ambient IOT device to the intermediate node to the intermediate node for the intermediate node to perform delay control.

[0449] Optionally, there may be multiple delay control methods.

[0450] In some embodiments, the transmission delay can be guaranteed by the configured UL resources, and the ambient IoT device or the intermediate node can perform data transmission according to the configured UL resources, and the configured UL resources meet the first delay requirement.

[0451] In some embodiments, the transmission delay can be guaranteed by a clear delay requirement indication of the first communication device (BS or intermediate node), and the ambient IoT device or intermediate node transmits data within the time indicated by the delay requirement, thereby controlling the transmission delay.

[0452] Based on the above solution, the communication method provided by the embodiment of the present disclosure is further illustrated below with two examples.

[0453] Network topology 1: Ambient IoT device -> BS -> … -> IoT server

[0454] Network topology 1: Ambient IoT device->intermediate node->BS->…->IoT server

[0455] Example 1: The first latency requirement is defined as the transmission latency from the tag to the reader.

[0456] The reader (such as a BS or an intermediate node) configures the tag (such as an ambient IoT device) to send data according to the first delay requirement.

[0457] The first latency requirement may be determined by the Reader based on the following method:

[0458] In some embodiments, the Reader determines the first delay requirement based on the transmission delay requirement of the protocol specification.

[0459] In some embodiments, an Ambient IoT server or network device (e.g., a core network function node or a base station node) determines a first latency requirement and sends the first latency requirement to a Reader. The first latency requirement may be determined based on a protocol specification latency requirement and / or a segmentation requirement (e.g., uplink and downlink segmentation, segmentation based on policy or dynamic scheduling).

[0460] In some embodiments, the Reader can configure UL resources for the Tag that meet the first delay requirement. The UL resources are used for the Tag to send data within the transmission delay indicated by the first delay requirement. It can be understood that if the transmission delay exceeds the first delay requirement, the Tag has no UL resources available for data sending.

[0461] In some embodiments, the Reader may send a delay requirement indication to the Tag, where the delay requirement indication is used to instruct the Tag to send data within the transmission delay indicated by the first delay requirement.

[0462] Optionally, the tag may be the first, last, or any tag of the sent data.

[0463] Example 2: The first delay requirement is defined as the transmission delay from the tag to the BS

[0464] For network topology 1, BS is the Reader in Example 1. The relevant process can be found in Example 1 and will not be repeated here.

[0465] For network topology 2, the transmission delay from the Ambient IoT device to the intermediate node, and the transmission delay from the intermediate node to the BS can be based on the protocol specification delay requirements, and / or, the network device (such as the core network function node or the BS) or the Ambient IoT server is determined according to the segmentation requirements, and controlled by the intermediate node and the BS, respectively.

[0466] The transmission delay from the Ambient IoT device to the intermediate node is determined by the intermediate node configuring a tag (such as Ambient IoT Device) according to the delay requirements for data transmission. The specific method is shown in Example 1 and will not be repeated here.

[0467] The transmission delay from the intermediate node to the BS can be adjusted by the BS configuring the intermediate node to send data according to the delay requirement. The specific method is shown in Example 1 and will not be repeated here.
