[0069] 1) A-IoT communication technology

[0070] A-IoT communication can adopt energy harvesting and backscatter communication technology. The A-IoT communication network is composed of network equipment and A-IoT devices, as shown in Figure 2, which shows the structure diagram of the A-IoT communication system involved in this application. Among them, the network equipment is used to send wireless power supply signals, downlink communication signals and receive backscatter signals from A-IoT devices to A-IoT devices. A basic A-IoT device includes an energy harvesting module, a backscatter communication module and a low-power computing module. In addition, the A-IoT device may also include a memory or sensor for storing some basic information (such as item identification, etc.) or obtaining sensor data such as ambient temperature and ambient humidity.

[0071] The key technologies of A-IoT communication mainly include radio frequency energy harvesting and backscatter communication.

[0072] -RF Power Harvesting

[0073] Please refer to Figure 3, which shows the RF energy harvesting principle involved in this application. As shown in Figure 3, the RF energy harvesting module uses the principle of electromagnetic induction to harvest electromagnetic wave energy from space, thereby obtaining the energy required to operate A-IoT devices, such as those used to drive low-power demodulation and modulation modules, sensors, and memory access. As a result, A-IoT devices do not require traditional batteries.

[0074] -Back Scattering

[0075] Please refer to Figure 4, which shows the schematic diagram of the backscatter communication involved in this application. As shown in Figure 4, the A-IoT device receives the wireless signal sent by the network, modulates the wireless signal, loads the information to be sent, and radiates the modulated signal from the antenna. This information transmission process is called backscatter communication. Backscatter and load modulation functions are inseparable. Load modulation adjusts and controls the circuit parameters of the oscillation circuit of the A-IoT device according to the beat of the data stream, so that parameters such as the impedance of the electronic tag change accordingly, thereby completing the modulation process. Load modulation technology mainly includes two methods: resistive load modulation and capacitive load modulation. In resistive load modulation, a resistor is connected in parallel to the load, and the resistor is turned on or off based on the control of the binary data stream. Please refer to Figure 5, which shows the schematic diagram of the circuit of resistive load modulation involved in this application. The on and off of the resistor will cause the circuit voltage to change, thereby realizing amplitude-shift keying (ASK), that is, the modulation and transmission of the signal is achieved by adjusting the amplitude of the backscattered signal of the A-IoT device. Similarly, in capacitive load modulation, the resonant frequency of the circuit can be changed by switching the capacitor on and off, realizing frequency-shift keying (FSK). That is, the signal is modulated and transmitted by adjusting the operating frequency of the backscattered signal of the A-IoT device.

[0076] It can be seen that A-IoT devices use load modulation to modulate the incoming signal, thereby realizing the backscatter communication process. Therefore, A-IoT devices have significant advantages:

[0077] (1) A-IoT devices do not actively transmit signals, so they do not require complex RF links, such as power amplifiers (PAs) and RF filters.

[0078] (2) A-IoT devices do not need to actively generate high-frequency signals, so they do not require high-frequency crystal oscillators;

[0079] (3) With the help of backscatter communication, terminal signal transmission does not need to consume the energy of the A-IoT device itself.

[0080] 2) Classification of A-IoT devices

[0081] Based on current 3GPP discussions, A-IoT devices can be categorized into two types based on their energy storage capabilities and the ability to generate RF signals for signal transmission.

[0082] Device type 1: The transmission power is about 1uW, and it has energy storage function. It does not have independent signal generation and uplink and downlink signal amplification functions. Signal transmission relies on backscattering.

[0083] Device type 2: has a transmission power of several hundred uW, has energy storage function, has uplink and downlink signal amplification function, and can independently generate signals or use backscattering to send signals.

[0084] During standardization discussions, A-IoT has also been referred to as the zero-power IoT, and in some technical literature, it's also referred to as the passive IoT. Ambient IoT devices are IoT devices that use various environmental energies, such as radio frequency energy, light energy, solar energy, thermal energy, and mechanical energy, to power themselves. These devices may have no energy storage capacity or very limited energy storage capacity (such as using capacitors with a capacity of tens of uF). Ambient IoT devices offer many advantages, including no conventional batteries, no maintenance, small size, low complexity, low cost, and a long lifespan.

[0085] 3) A-IoT industry applications, use cases, and business models

[0086] A-IoT supports many industrial applications, such as automated warehousing, smart homes, smart agriculture, and finding personal belongings.

[0087] Automated warehousing: Automated warehouse inventory scenarios involve multiple stages, including verification and unloading, warehousing, inventory counting, outbound delivery, and inspection and loading. As goods are transferred, stored, and inventoried, a vast amount of warehouse information is generated. This information is typically characterized by frequent data access operations and large data volumes. Ambient IoT devices are connected to items of varying value and purpose, such as pallets and individual products, and equipped with relevant communication equipment. Information exchange between communication devices and tags enables efficient and accurate management of inventory and storage information at each stage.

[0088] For automated warehousing, 3GPP has defined an inventory use case, which aims to discover the presence of goods (such as boxes, drawers, packages, tools, etc.) within a specific area. Upon receiving a request from the network within a specific area, the A-IoT devices attached to these goods report their associated identifiers to the network, optionally along with other information such as status, measurement results, and location. This service model falls under the DO-DTT (Device Originated-Device Terminated Triggered) model.

[0089] A-IoT devices used in warehousing and logistics may employ various communication types, such as backscatter and active transmission. When the network initiates an inventory request, polling request, or paging message, how the A-IoT device selects uplink transmission resources is a critical issue. If all devices choose to transmit on the same uplink carrier, severe interference and transmission failures will result.

[0090] The subsequent embodiments of this application design a set of solutions for uplink access and transmission of A-IoT devices, which can improve the efficiency of access and transmission of A-IoT devices.

[0091] Please refer to FIG6 , which shows a flowchart of an uplink transmission method provided by an embodiment of the present application. The method can be performed by an A-IoT device, wherein the A-IoT device can be the ambient energy IoT device 130 in the network architecture shown in FIG1 . The method can include the following steps:

[0092] Step 601: Access and transmit with a network device through uplink resources corresponding to the communication type of the A-IoT device; wherein uplink resources corresponding to different communication types do not overlap.

[0093] The aforementioned access transmission may also refer to network access initiated by the A-IoT device to the network device, such as random access. The aforementioned access transmission process between the A-IoT device and the network device may also be referred to as the random access process initiated by the A-IoT device to the network device.

[0094] The communication types may include one or both of backscatter communication and active transmission communication. For A-IoT devices of different communication types, the uplink resources used for access transmission with network devices do not overlap.

[0095] The above-mentioned non-overlapping uplink resources may mean that the two uplink resources are completely different or partially different.

[0096] To sum up, according to the scheme shown in the embodiment of the present application, the A-IoT device can access and transmit with the network device through the uplink resources corresponding to the communication type of the A-IoT device, and the uplink resources corresponding to different communication types do not overlap; that is, through the above scheme, A-IoT devices of different communication types can use non-overlapping uplink resources for access and transmission, thereby avoiding transmission interference when a large number of A-IoT devices perform uplink access and transmission as much as possible, reducing the failure of A-IoT device access and transmission, and improving the efficiency of A-IoT device access and transmission.

[0097] Please refer to FIG7 , which shows a flowchart of an uplink transmission method provided by an embodiment of the present application. The method may be performed by a network device, wherein the network device may be the network device 110 in the network architecture shown in FIG1 . The method may include the following steps:

[0098] Step 701: Receive access transmission from an A-IoT device through uplink resources corresponding to the communication type of the A-IoT device; wherein uplink resources corresponding to different communication types do not overlap.

[0099] To sum up, according to the scheme shown in the embodiment of the present application, the A-IoT device can access and transmit with the network device through the uplink resources corresponding to the communication type of the A-IoT device, and the uplink resources corresponding to different communication types do not overlap; that is, through the above scheme, A-IoT devices of different communication types can use non-overlapping uplink resources for access and transmission, thereby avoiding transmission interference when a large number of A-IoT devices perform uplink access and transmission as much as possible, reducing the failure of A-IoT device access and transmission, and improving the efficiency of A-IoT device access and transmission.

[0100] Please refer to FIG8 , which shows a flowchart of an uplink transmission method provided by an embodiment of the present application. The method may be performed by an A-IoT device, wherein the A-IoT device may be the ambient energy IoT device 130 in the network architecture shown in FIG1 . The method may include the following steps:

[0101] Step 801: During access and transmission with a network device, indicate the communication type of the A-IoT device to the network device.

[0102] To sum up, in the solution shown in the embodiment of the present application, during the process of access and transmission between the A-IoT device and the network device, the A-IoT device can indicate its own communication type to the network device, so that the network device can promptly know the communication type of the accessed A-IoT device, and then conduct subsequent communication with the A-IoT device through the corresponding communication type, thereby improving the efficiency and accuracy of A-IoT communication between the A-IoT device and the network device.

[0103] Please refer to FIG9 , which shows a flowchart of an uplink transmission method provided by an embodiment of the present application. The method may be performed by a network device, wherein the network device may be the network device 110 in the network architecture shown in FIG1 . The method may include the following steps:

[0104] Step 901: Obtain the communication type of the A-IoT device indicated by the A-IoT device during access and transmission with the network device.

[0105] To sum up, in the solution shown in the embodiment of the present application, during the process of access and transmission between the A-IoT device and the network device, the A-IoT device can indicate its own communication type to the network device, so that the network device can promptly know the communication type of the accessed A-IoT device, and then conduct subsequent communication with the A-IoT device through the corresponding communication type, thereby improving the efficiency and accuracy of A-IoT communication between the A-IoT device and the network device.

[0106] Based on the solutions shown in Figures 6 to 9 above, please refer to Figure 10, which shows a flowchart of an uplink transmission method provided by an embodiment of the present application. The method can be interactively executed by an Ambient Energy Internet of Things (A-IoT) device and a network device. The A-IoT device can be the Ambient Energy Internet of Things device 130 in the network architecture shown in Figure 1, and the network device can be the network device 110 in the network architecture shown in Figure 1. The method can include the following steps:

[0107] In step 1001, the A-IoT device accesses and transmits to the network device through the uplink resources corresponding to the communication type of the A-IoT device; accordingly, the network device receives the access and transmission made by the A-IoT device through the uplink resources corresponding to the communication type of the A-IoT device; wherein the uplink resources corresponding to different communication types do not overlap.

[0108] In some embodiments, the A-IoT device accesses and transmits with the network device through the uplink resources corresponding to the communication type of the A-IoT device, including: upon receiving an access trigger message, accessing and transmitting with the network device through the uplink resources corresponding to the communication type of the A-IoT device.

[0109] Correspondingly, the network device receives the access transmission performed by the A-IoT device through the uplink resources corresponding to the communication type of the A-IoT device, including: receiving the access transmission performed by the A-IoT device through the uplink resources corresponding to the communication type of the A-IoT device when the A-IoT device receives the access trigger message.

[0110] In the above embodiments of the present application, the A-IoT device can initiate random access to the network device under the trigger of the access trigger message, thereby ensuring the flexibility and controllability of the random access initiated by the A-IoT device, thereby improving the accuracy and access efficiency of the random access initiated by the A-IoT device.

[0111] The access trigger message can also be a message sent by a device other than a network device to an A-IoT device. For example, in an IoT system, in addition to A-IoT devices and network devices, it also includes a control device / management device. The control device / management device can periodically / irregularly send access trigger messages to surrounding A-IoT devices via IoT communication methods to trigger the A-IoT device to initiate random access to the network device, thereby enabling communication between the A-IoT device and the network device.

[0112] Alternatively, the access trigger message may be a message generated internally by the A-IoT device. For example, the A-IoT device may execute access trigger logic internally. For example, the A-IoT device may maintain a timer that starts when the A-IoT device is disconnected from the network device and is cleared when the A-IoT device initiates random access to the network device. When the timer reaches the set duration, the A-IoT device may generate the access trigger message to trigger the A-IoT device to initiate random access to the network device. For another example, the A-IoT device may detect the amount of data to be uploaded in the internal cache. When the data amount reaches a preset data amount threshold, the A-IoT device may generate the access trigger message to trigger the A-IoT device to initiate random access to the network device.

[0113] Alternatively, the access trigger message may be a message sent by a network device to an A-IoT device. For example, when a network device needs to discover surrounding A-IoT devices or communicate with them, it may send an access trigger message to the surrounding A-IoT devices.

[0114] In some embodiments, the access trigger message includes one or more of the following messages: a paging message, a query message, a polling message, and an inventory request message.

[0115] In the above embodiment of the present application, when the above access trigger message is a message sent by the network device to the A-IoT device, the above access trigger message may be one or more of a paging message, a query message, a polling message, and an inventory request message.

[0116] In the above embodiments of the present application, after the network device initiates a paging message, a query message, a polling message and / or an inventory request message, the A-IoT device can initiate an uplink access transmission to the network device through the uplink resources corresponding to its own communication type, so that when the network device triggers multiple different types of A-IoT devices to initiate random access, A-IoT devices of different communication types use non-overlapping uplink resources for access transmission, thereby avoiding transmission interference when a large number of A-IoT devices perform uplink access transmission.

[0117] In some embodiments, when the communication type is a backscatter communication type, the uplink resources corresponding to the communication type include a first uplink resource; when the communication type is an active transmission communication type, the uplink resources corresponding to the communication type include a second uplink resource; the first uplink resource and the second uplink resource do not overlap.

[0118] In the above embodiments of the present application, for A-IoT devices of the backscatter communication type and A-IoT devices of the active transmission communication type, these two types of A-IoT devices respectively perform uplink access transmission through non-overlapping uplink resources, so that when the A-IoT devices of the backscatter communication type and the active transmission communication type perform access transmission, they can use non-overlapping uplink resources, thereby controlling the uplink access process of the A-IoT devices of the backscatter communication type and the A-IoT devices of the active transmission communication type on non-overlapping uplink resources, so that when there are A-IoT devices of the backscatter communication type and A-IoT devices of the active transmission communication type in the system at the same time and they need to access the network, transmission interference when a large number of A-IoT devices perform uplink access transmission can be avoided as much as possible.

[0119] In some embodiments, the first uplink resource includes a first uplink frequency domain resource, and the second uplink resource includes a second uplink frequency domain resource; the first uplink frequency domain resource and the second uplink frequency domain resource do not overlap.

[0120] In the above embodiments of the present application, when A-IoT devices of backscatter communication type and active transmission communication type perform access and transmission, random access can be performed using non-overlapping uplink resources in the frequency domain, thereby controlling the access and transmission of A-IoT devices of different communication types in the frequency domain. That is, the uplink access process of A-IoT devices of backscatter communication type and A-IoT devices of active transmission communication type can be controlled on non-overlapping uplink frequency domain resources, so that when there are both A-IoT devices of backscatter communication type and A-IoT devices of active transmission communication type in the system and they need to access the network, transmission interference in the frequency domain when a large number of A-IoT devices perform uplink access and transmission can be avoided as much as possible.

[0121] In some embodiments, when the first uplink frequency domain resources and the second uplink frequency domain resources do not overlap, other types of resources in the first uplink resources and the second uplink resources may overlap or not overlap; for example, the time domain resources in the first uplink resources and the time domain resources in the second uplink resources may overlap or not overlap; for another example, the code domain resources in the first uplink resources and the code domain resources in the second uplink resources may overlap or not overlap.

[0122] In some embodiments, the first uplink frequency domain resource includes one or more frequency domain resources; the second uplink frequency domain resource includes one or more frequency domain resources.

[0123] Among them, the first uplink frequency domain resource used by an A-IoT device of the backscatter communication type for access and transmission may include a frequency domain resource A; the second uplink frequency domain resource used by an A-IoT device of the active transmission communication type for access and transmission may include another frequency domain resource B; the frequency domain resource A and the frequency domain resource B do not overlap; among them, the frequency domain resources included in the uplink frequency domain resources used by A-IoT devices of different backscatter communication types for access and transmission may be different or the same; the frequency domain resources included in the uplink frequency domain resources used by A-IoT devices of different active transmission communication types for access and transmission may be different or the same.

[0124] Alternatively, the first uplink frequency domain resource used by an A-IoT device of the backscatter communication type for access transmission may include a frequency domain resource A; the second uplink frequency domain resource used by an A-IoT device of the active transmission communication type for access transmission may include multiple frequency domain resources B; the frequency domain resource A does not overlap with any of the multiple frequency domain resources B.

[0125] Alternatively, the first uplink frequency domain resources used by an A-IoT device of the backscatter communication type for access transmission may include multiple frequency domain resources A; the second uplink frequency domain resources used by an A-IoT device of the active transmission communication type for access transmission may include multiple frequency domain resources B; any frequency domain resource A and any frequency domain resource B do not overlap.

[0126] Alternatively, the first uplink frequency domain resource used by an A-IoT device of the backscatter communication type for access transmission may include multiple frequency domain resources A; the second uplink frequency domain resource used by an A-IoT device of the active transmission communication type for access transmission may include a frequency domain resource B; any frequency domain resource A and the frequency domain resource B do not overlap.

[0127] In the above embodiments of the present application, the A-IoT device may have one frequency domain resource for uplink transmission, which can simplify the complexity of configuration / selection of frequency domain resources for uplink access transmission of the A-IoT device and improve the efficiency of uplink access transmission of the A-IoT device; or, the A-IoT device may have multiple frequency domain resources for uplink transmission, thereby improving the flexibility of the frequency domain resources used by the A-IoT device for uplink access transmission and further reducing the transmission interference in the frequency domain when the A-IoT device performs uplink access transmission.

[0128] In some embodiments, when the communication type of the A-IoT device is a backscatter communication type and the first uplink frequency domain resource includes multiple frequency domain resources, access and transmission are performed with the network device through the uplink resource corresponding to the communication type of the A-IoT device, including: according to the first frequency domain resource selection method, one frequency domain resource is selected from the multiple frequency domain resources included in the first uplink frequency domain resource to initiate random access to the network device; when the communication type of the A-IoT device is an active transmission communication type and the second uplink frequency domain resource includes multiple frequency domain resources, access and transmission are performed with the network device through the uplink resource corresponding to the communication type of the A-IoT device, including: according to the second frequency domain resource selection method, one frequency domain resource is selected from the multiple frequency domain resources included in the second uplink frequency domain resource to initiate random access to the network device.

[0129] That is to say, when the communication type of the A-IoT device is a backscatter communication type and the first uplink frequency domain resources include multiple frequency domain resources, the frequency domain resource for the A-IoT device to initiate random access transmission is a frequency domain resource selected from the multiple frequency domain resources included in the first uplink frequency domain resources according to the first frequency domain resource selection method; when the communication type of the A-IoT device is an active transmission communication type and the second uplink frequency domain resources include multiple frequency domain resources, the frequency domain resource for the A-IoT device to initiate random access transmission is a frequency domain resource selected from the multiple frequency domain resources included in the second uplink frequency domain resources according to the second frequency domain resource selection method.

[0130] In the above embodiments of the present application, for an A-IoT device of backscatter communication type, when the first uplink frequency domain resource of the A-IoT device includes multiple frequency domain resources, the A-IoT device can select one frequency domain resource from them for uplink access transmission through a predetermined frequency domain resource selection method. Correspondingly, for an A-IoT device of active transmission communication type, when the second uplink frequency domain resource of the A-IoT device includes multiple frequency domain resources, the A-IoT device can select one frequency domain resource from them for uplink access transmission through a predetermined frequency domain resource selection method. The above scheme improves the flexibility of the frequency domain resources used by the A-IoT device for uplink access transmission, and further reduces the transmission interference in the frequency domain when the A-IoT device performs uplink access transmission.

[0131] The first frequency domain resource selection method and the second frequency domain resource selection method may be the same or different.

[0132] In some embodiments, the first frequency domain resource selection method includes one or more of the following methods: randomly selecting frequency domain resources, selecting frequency domain resources based on the identification information of the A-IoT device, and selecting frequency domain resources based on the weight of the frequency domain resources; the second frequency domain resource selection method includes one or more of the following methods: randomly selecting frequency domain resources, selecting frequency domain resources based on the identification information of the A-IoT device, and selecting frequency domain resources based on the weight of the frequency domain resources.

[0133] Among them, for an A-IoT device of the backscatter communication type, when the first uplink frequency domain resource of the A-IoT device includes multiple frequency domain resources, the A-IoT device can randomly select one of the frequency domain resources for uplink access transmission.

[0134] Alternatively, the A-IoT device may also use the identification information of the A-IoT device to select a frequency domain resource for uplink access transmission through a pre-set algorithm. For example, the device ID or other device identification of the A-IoT device may be used to perform a modulo operation on the number of multiple frequency domain resources included in the first uplink frequency domain resource, and the frequency domain resource with the corresponding number may be selected for uplink access transmission based on the result of the modulo operation.

[0135] Alternatively, the first uplink frequency domain resource includes multiple frequency domain resources that may have respective weights. The A-IoT device may also combine the respective weights of the multiple frequency domain resources to randomly select a frequency domain resource from the multiple frequency domain resources included in the first uplink frequency domain resource for uplink access transmission. For example, the higher the weight of the frequency domain resource, the higher the probability of being randomly selected, and correspondingly, the lower the weight of the frequency domain resource, the lower the probability of being randomly selected; for example, assuming that the first uplink frequency domain resource includes frequency domain resource 1, frequency domain resource 2 and frequency domain resource 3, where the weight of frequency domain resource 1 is 0.5, the weight of frequency domain resource 2 is 0.3, and the weight of frequency domain resource 3 is 0.2, then when the A-IoT device selects frequency domain resources from frequency domain resource 1, frequency domain resource 2 and frequency domain resource 3, frequency domain resource 1 has a 50% probability of being selected, frequency domain resource 2 has a 30% probability of being selected, and frequency domain resource 3 has a 20% probability of being selected.

[0136] Similarly, for an A-IoT device of the active transmission communication type, when the second uplink frequency domain resource of the A-IoT device includes multiple frequency domain resources, the A-IoT device can randomly select one of the frequency domain resources for uplink access transmission.

[0137] Alternatively, the A-IoT device may also use the identification information of the A-IoT device to select a frequency domain resource for uplink access transmission through a pre-set algorithm. For example, the device ID or other device identification of the A-IoT device may be used to perform a modulo operation on the number of multiple frequency domain resources included in the second uplink frequency domain resource, and the frequency domain resource with the corresponding number may be selected for uplink access transmission based on the result of the modulo operation.

[0138] Alternatively, the second uplink frequency domain resources include multiple frequency domain resources that may have respective weights. The A-IoT device may also combine the respective weights of the multiple frequency domain resources to randomly select one frequency domain resource from the multiple frequency domain resources included in the second uplink frequency domain resources for uplink access transmission. For example, the higher the weight of the frequency domain resource, the higher the probability of being randomly selected. Correspondingly, the lower the weight of the frequency domain resource, the lower the probability of being randomly selected.

[0139] In the scheme shown in the above-mentioned embodiment of the present application, when the uplink frequency domain resources used by the A-IoT device for access transmission include multiple frequency domain resources, the A-IoT device can select one frequency domain resource from the multiple frequency domain resources for uplink access transmission by random selection, random selection combined with weights, or calculation combined with identification information. Even if multiple A-IoT devices of the same communication type are configured with the same uplink frequency domain resources, the multiple A-IoT devices have the opportunity to select different frequency domain resources for uplink access transmission, thereby improving the flexibility of the frequency domain resources used by the A-IoT device for uplink access transmission, and further reducing the transmission interference in the frequency domain when the A-IoT device performs uplink access transmission.

[0140] In some embodiments, when the communication type of the A-IoT device is a backscatter communication type, the first uplink frequency domain resource is configured to the A-IoT device by the network device through at least one of the following methods: configuration through a system message, configuration through an access trigger message; when the communication type of the A-IoT device is an active transmission communication type, the second uplink frequency domain resource is configured to the A-IoT device by the network device through at least one of the following methods: configuration through a system message, configuration through an access trigger message.

[0141] In an embodiment of the present application, the network device can pre-configure the uplink frequency domain resources used by the A-IoT device for access transmission through system messages and access trigger messages.

[0142] For example, for a certain A-IoT device, the network device can configure the uplink frequency domain resources used for access transmission to the A-IoT device through a system message (such as a system broadcast message or a system message block); for example, the network device can carry a group of uplink frequency domain resources corresponding to various communication types in the system message; please refer to Figure 11, which shows a resource configuration diagram of a system message involved in an embodiment of the present application. As shown in Figure 11, in the above-mentioned system message, each communication type can correspond to a group of uplink frequency domain resources, each group of uplink frequency domain resources includes multiple uplink frequency domain resources, and each uplink frequency domain resource corresponds to the above-mentioned first uplink frequency domain resource or the second uplink frequency domain resource, that is, each uplink frequency domain resource includes one or more frequency domain resources, and the system message also indicates the range of the device ID corresponding to each uplink frequency domain resource. After receiving the system message, the A-IoT device determines the corresponding multiple uplink frequency domain resources according to its own communication type, and determines one of the multiple uplink frequency domain resources according to its own device ID as the uplink frequency domain resource used for its subsequent uplink access transmission.

[0143] For another example, for a certain A-IoT device, the network device can configure the uplink frequency domain resources used for access transmission to the A-IoT device through an access trigger message; for example, when the network device sends an access trigger message (such as the above-mentioned paging message, query message, polling message, or inventory request message) to the A-IoT device, the access trigger message can carry / indicate the uplink frequency domain resources used by the A-IoT device for uplink access transmission. For example, the access trigger message can directly include or indirectly indicate the range of the uplink frequency domain resources used by the A-IoT device for uplink access transmission.

[0144] For another example, for a certain A-IoT device, the network device can configure the uplink frequency domain resources used for access transmission to the A-IoT device through system messages and access trigger messages; for example, the network device can carry multiple uplink frequency domain resources corresponding to various communication types in the system message. After the A-IoT device receives the system message, it determines the corresponding multiple uplink frequency domain resources based on its own communication type; when the network device subsequently sends an access trigger message to the A-IoT device, it can carry / indicate an uplink frequency domain resource used by the A-IoT device for uplink access transmission through the access trigger message. For example, the access trigger message can directly include or indirectly indicate the uplink frequency domain resource used by the A-IoT device for uplink access transmission, which is the number of the multiple uplink frequency domain resources corresponding to the communication type of the A-IoT device.

[0145] Among them, for A-IoT devices of different communication types, the network device can use the same configuration method to configure uplink frequency domain resources, or use different configuration methods to configure uplink frequency domain resources.

[0146] In the scheme shown in the above embodiment of the present application, the network device can configure the uplink frequency domain resources used by the A-IoT device for access transmission through system messages and / or access trigger messages, thereby ensuring the controllability of the uplink frequency domain resource configuration used by each A-IoT device for access transmission, and thereby ensuring the efficiency and accuracy of the A-IoT device's access transmission.

[0147] In some embodiments, the frequency domain resources are carriers.

[0148] In the above embodiments of the present application, A-IoT devices of different communication types can initiate random access to network devices on non-overlapping carriers, so as to avoid transmission interference in the frequency domain when a large number of A-IoT devices perform random access as much as possible.

[0149] In some other embodiments, the above-mentioned frequency domain resources may also be frequency bands, frequency points, etc.

[0150] In some embodiments, the first uplink resource includes a first uplink time domain resource, and the second uplink resource includes a second uplink time domain resource; the first uplink time domain resource and the second uplink time domain resource do not overlap.

[0151] In the above embodiments of the present application, when A-IoT devices of backscatter communication type and active transmission communication type perform access and transmission, random access can be performed using non-overlapping uplink resources in the time domain, thereby controlling the access and transmission of A-IoT devices of different communication types in the time domain. That is, the uplink access process of A-IoT devices of backscatter communication type and A-IoT devices of active transmission communication type can be controlled on non-overlapping uplink time domain resources, thereby avoiding transmission interference in the time domain when a large number of A-IoT devices perform uplink access and transmission when there are both backscatter communication type A-IoT devices and active transmission communication type A-IoT devices that need to access the network in the system as much as possible.

[0152] In some embodiments, when the first uplink time domain resources and the second uplink time domain resources do not overlap, other types of resources in the first uplink resources and the second uplink resources may overlap or not overlap; for example, the frequency domain resources in the first uplink resources and the frequency domain resources in the second uplink resources may overlap or not overlap; for another example, the code domain resources in the first uplink resources and the code domain resources in the second uplink resources may overlap or not overlap.

[0153] In some embodiments, the first uplink time domain resource includes one or more time domain resources; and the second uplink time domain resource includes one or more time domain resources.

[0154] Among them, the first uplink time domain resource used by an A-IoT device of the backscatter communication type for access and transmission may include a time domain resource A; the second uplink time domain resource used by an A-IoT device of the active transmission communication type for access and transmission may include another time domain resource B; time domain resource A and time domain resource B do not overlap; among them, the time domain resources included in the uplink time domain resources used by A-IoT devices of different backscatter communication types for access and transmission may be different or the same; the time domain resources included in the uplink time domain resources used by A-IoT devices of different active transmission communication types for access and transmission may be different or the same.

[0155] Alternatively, the first uplink time domain resource used by an A-IoT device of the backscatter communication type for access transmission may include a time domain resource A; the second uplink time domain resource used by an A-IoT device of the active transmission communication type for access transmission may include multiple time domain resources B; the time domain resource A does not overlap with any of the multiple time domain resources B.

[0156] Alternatively, the first uplink time domain resources used by an A-IoT device of the backscatter communication type for access transmission may include multiple time domain resources A; the second uplink time domain resources used by an A-IoT device of the active transmission communication type for access transmission may include multiple time domain resources B; any time domain resource A and any time domain resource B do not overlap.

[0157] Alternatively, the first uplink time domain resource used by an A-IoT device of the backscatter communication type for access transmission may include multiple time domain resources A; the second uplink time domain resource used by an A-IoT device of the active transmission communication type for access transmission may include one time domain resource B; any time domain resource A and the time domain resource B do not overlap.

[0158] In the above embodiments of the present application, the A-IoT device may have one time domain resource for uplink transmission, which can simplify the complexity of configuration / selection of time domain resources for uplink access transmission of the A-IoT device and improve the efficiency of uplink access transmission of the A-IoT device; or, the A-IoT device may have multiple time domain resources for uplink transmission, thereby improving the flexibility of the time domain resources used by the A-IoT device for uplink access transmission and further reducing the transmission interference in the time domain when the A-IoT device performs uplink access transmission.

[0160] That is to say, when the communication type of the A-IoT device is a backscatter communication type and the first uplink time domain resource includes multiple time domain resources, the time domain resource for the A-IoT device to initiate random access transmission is a time domain resource selected from the multiple time domain resources included in the first uplink time domain resource according to the first time domain resource selection method; when the communication type of the A-IoT device is an active transmission communication type and the second uplink time domain resource includes multiple time domain resources, the time domain resource for the A-IoT device to initiate random access transmission is a time domain resource selected from the multiple time domain resources included in the second uplink time domain resource according to the second time domain resource selection method.

[0184] Among them, the first uplink code domain resource used by an A-IoT device of the backscatter communication type for access transmission may include a code domain resource A; the second uplink code domain resource used by an A-IoT device of the active transmission communication type for access transmission may include another code domain resource B; the code domain resource A and the code domain resource B do not overlap; among them, the code domain resources contained in the uplink code domain resources used by A-IoT devices of different backscatter communication types for access transmission may be different or the same; the code domain resources contained in the uplink code domain resources used by A-IoT devices of different active transmission communication types for access transmission may be different or the same.

[0185] Alternatively, the first uplink code domain resource used by an A-IoT device of the backscatter communication type for access transmission may include a code domain resource A; the second uplink code domain resource used by an A-IoT device of the active transmission communication type for access transmission may include multiple code domain resources B; the code domain resource A does not overlap with any of the multiple code domain resources B.

[0186] Alternatively, the first uplink code domain resources used by an A-IoT device of the backscatter communication type for access transmission may include multiple code domain resources A; the second uplink code domain resources used by an A-IoT device of the active transmission communication type for access transmission may include multiple code domain resources B; any code domain resource A and any code domain resource B do not overlap.

[0187] Alternatively, the first uplink code domain resources used by an A-IoT device of the backscatter communication type for access transmission may include multiple code domain resources A; the second uplink code domain resources used by an A-IoT device of the active transmission communication type for access transmission may include a code domain resource B; any code domain resource A and the code domain resource B do not overlap.

[0188] In the above embodiments of the present application, the A-IoT device may have one code domain resource for uplink transmission, which can simplify the complexity of configuration / selection of code domain resources for uplink access transmission of the A-IoT device and improve the efficiency of uplink access transmission of the A-IoT device; or, the A-IoT device may have multiple code domain resources for uplink transmission, thereby improving the flexibility of the code domain resources used by the A-IoT device for uplink access transmission and further reducing the transmission interference in the code domain when the A-IoT device performs uplink access transmission.

[0189] In some embodiments, when the communication type of the A-IoT device is a backscatter communication type and the first uplink code domain resource includes multiple code domain resources, access and transmission are performed with the network device through the uplink resource corresponding to the communication type of the A-IoT device, including: according to the first code domain resource selection method, selecting a code domain resource from the multiple code domain resources included in the first uplink code domain resource to initiate random access to the network device; when the communication type of the A-IoT device is an active transmission communication type and the second uplink code domain resource includes multiple code domain resources, access and transmission are performed with the network device through the uplink resource corresponding to the communication type of the A-IoT device, including: according to the second code domain resource selection method, selecting a code domain resource from the multiple code domain resources included in the second uplink code domain resource to initiate random access to the network device.

[0190] That is to say, when the communication type of the A-IoT device is a backscatter communication type and the first uplink code domain resources include multiple code domain resources, the code domain resource for the A-IoT device to initiate random access transmission is a code domain resource selected from the multiple code domain resources included in the first uplink code domain resources according to the first code domain resource selection method; when the communication type of the A-IoT device is an active transmission communication type and the second uplink code domain resources include multiple code domain resources, the code domain resource for the A-IoT device to initiate random access transmission is a code domain resource selected from the multiple code domain resources included in the second uplink code domain resources according to the second code domain resource selection method.

[0191] In the above embodiments of the present application, for an A-IoT device of backscatter communication type, when the first uplink code domain resource of the A-IoT device includes multiple code domain resources, the A-IoT device can select one code domain resource from them for uplink access transmission through a predetermined code domain resource selection method. Correspondingly, for an A-IoT device of active transmission communication type, when the second uplink code domain resource of the A-IoT device includes multiple code domain resources, the A-IoT device can select one code domain resource from them for uplink access transmission through a predetermined code domain resource selection method. The above scheme improves the flexibility of the code domain resources used by the A-IoT device for uplink access transmission, and further reduces the transmission interference in the code domain when the A-IoT device performs uplink access transmission.

[0192] The first code domain resource selection method and the second code domain resource selection method may be the same or different.

[0193] In some embodiments, the first code domain resource selection method includes one or more of the following methods: randomly selecting code domain resources, selecting code domain resources according to the identification information of the A-IoT device, and selecting code domain resources according to the weight of the code domain resources; the second code domain resource selection method includes one or more of the following methods: randomly selecting code domain resources, selecting code domain resources according to the identification information of the A-IoT device, and selecting code domain resources according to the weight of the code domain resources.

[0194] Among them, for an A-IoT device of the backscatter communication type, when the first uplink code domain resource of the A-IoT device includes multiple code domain resources, the A-IoT device can randomly select one of the code domain resources for uplink access transmission.

[0195] Alternatively, the A-IoT device may also use the identification information of the A-IoT device to select a code domain resource for uplink access transmission through a pre-set algorithm. For example, the device ID or other device identification of the A-IoT device may be used to perform a modulo operation on the number of multiple code domain resources contained in the first uplink code domain resource, and the code domain resource with the corresponding number may be selected for uplink access transmission based on the result of the modulo operation.

[0196] Alternatively, the first uplink code domain resource includes multiple code domain resources that may have respective weights. The A-IoT device may also combine the respective weights of the multiple code domain resources to randomly select a code domain resource from the multiple code domain resources included in the first uplink code domain resource for uplink access transmission. For example, the higher the weight of the code domain resource, the higher the probability of being randomly selected, and correspondingly, the lower the weight of the code domain resource, the lower the probability of being randomly selected; for example, assuming that the first uplink code domain resource includes code domain resource 1, code domain resource 2, and code domain resource 3, where the weight of code domain resource 1 is 0.5, the weight of code domain resource 2 is 0.3, and the weight of code domain resource 3 is 0.2, then when the A-IoT device selects code domain resources from code domain resource 1, code domain resource 2, and code domain resource 3, code domain resource 1 has a 50% probability of being selected, code domain resource 2 has a 30% probability of being selected, and code domain resource 3 has a 20% probability of being selected.

[0197] Similarly, for an A-IoT device of the active transmission communication type, when the second uplink code domain resource of the A-IoT device includes multiple code domain resources, the A-IoT device can randomly select one of the code domain resources for uplink access transmission.

[0198] Alternatively, the A-IoT device may also use the identification information of the A-IoT device to select a code domain resource for uplink access transmission through a pre-set algorithm. For example, the device ID or other device identification of the A-IoT device may be used to perform a modulo operation on the number of multiple code domain resources contained in the second uplink code domain resource, and the code domain resource with the corresponding number may be selected for uplink access transmission based on the result of the modulo operation.

[0199] Alternatively, the second uplink code domain resources include multiple code domain resources that may have respective weights. The A-IoT device may also combine the respective weights of the multiple code domain resources to randomly select a code domain resource from the multiple code domain resources included in the second uplink code domain resources for uplink access transmission. For example, the higher the weight of the code domain resource, the higher the probability of being randomly selected. Correspondingly, the lower the weight of the code domain resource, the lower the probability of being randomly selected.

[0200] In the scheme shown in the above embodiment of the present application, when the uplink code domain resources used by the A-IoT device for access transmission include multiple code domain resources, the A-IoT device can select one code domain resource from the multiple code domain resources for uplink access transmission by random selection, random selection combined with weights, or calculation combined with identification information. Even if multiple A-IoT devices of the same communication type are configured with the same uplink code domain resources, the multiple A-IoT devices have the opportunity to select different code domain resources for uplink access transmission, thereby improving the flexibility of the code domain resources used by the A-IoT device for uplink access transmission, and further reducing the transmission interference in the code domain when the A-IoT device performs uplink access transmission.

[0201] In some embodiments, when the communication type of the A-IoT device is a backscatter communication type, the first uplink code domain resource is configured to the A-IoT device by the network device through at least one of the following methods: configuration through a system message, configuration through an access trigger message; when the communication type of the A-IoT device is an active transmission communication type, the second uplink code domain resource is configured to the A-IoT device by the network device through at least one of the following methods: configuration through a system message, configuration through an access trigger message.

[0202] In an embodiment of the present application, the network device may pre-configure the uplink code domain resources used by the A-IoT device for access transmission through system messages and access trigger messages.

[0203] For example, for a certain A-IoT device, the network device can configure the uplink code domain resources used for access transmission to the A-IoT device through a system message (such as a system broadcast message or a system message block); for example, the network device can carry a group of uplink code domain resources corresponding to various communication types in the system message; please refer to Figure 13, which shows a resource configuration diagram of a system message involved in an embodiment of the present application. As shown in Figure 13, in the above-mentioned system message, each communication type can correspond to a group of uplink code domain resources, each group of uplink code domain resources includes multiple uplink code domain resources, and each uplink code domain resource corresponds to the above-mentioned first uplink code domain resource or the second uplink code domain resource, that is, each uplink code domain resource includes one or more code domain resources, and the system message also indicates the range of the device ID corresponding to each uplink code domain resource. After receiving the system message, the A-IoT device determines the corresponding multiple uplink code domain resources according to its own communication type, and determines one of the multiple uplink code domain resources according to its own device ID as the uplink code domain resource used for its subsequent uplink access transmission.

[0204] For another example, for a certain A-IoT device, the network device can configure the uplink code domain resources used for access transmission to the A-IoT device through an access trigger message; for example, when the network device sends an access trigger message (such as the above-mentioned paging message, query message, polling message, or inventory request message) to the A-IoT device, the access trigger message can carry / indicate the uplink code domain resources used by the A-IoT device for uplink access transmission. For example, the access trigger message can directly include or indirectly indicate the range of the uplink code domain resources used by the A-IoT device for uplink access transmission.

[0205] For another example, for a certain A-IoT device, the network device can configure the uplink code domain resources used for access transmission to the A-IoT device through system messages and access trigger messages; for example, the network device can carry multiple uplink code domain resources corresponding to various communication types in the system message. After the A-IoT device receives the system message, it determines the corresponding multiple uplink code domain resources based on its own communication type; when the network device subsequently sends an access trigger message to the A-IoT device, it can carry / indicate an uplink code domain resource used by the A-IoT device for uplink access transmission through the access trigger message. For example, the access trigger message can directly include or indirectly indicate the uplink code domain resource used by the A-IoT device for uplink access transmission, and the number of the uplink code domain resource corresponding to the communication type of the A-IoT device.

[0206] Among them, for A-IoT devices of different communication types, the network device can use the same configuration method to configure the uplink code domain resources, or use different configuration methods to configure the uplink code domain resources.

[0207] In the scheme shown in the above embodiment of the present application, the network device can configure the uplink code domain resources used by the A-IoT device for access transmission through system messages and / or access trigger messages, thereby ensuring the controllability of the uplink code domain resource configuration used by each A-IoT device for access transmission, thereby ensuring the efficiency and accuracy of the access transmission of the A-IoT device.

[0208] In some embodiments, the code domain resource is a random access preamble.

[0209] In the above embodiments of the present application, A-IoT devices of different communication types can initiate random access to the network device through non-overlapping random access preamble codes, so as to avoid transmission interference in the code domain when a large number of A-IoT devices perform random access as much as possible.

[0210] In step 1002, the A-IoT device indicates the communication type of the A-IoT device to the network device during access and transmission with the network device; accordingly, the network device obtains the communication type of the A-IoT device indicated by the A-IoT device during access and transmission with the network device.

[0211] In the above embodiments of the present application, the A-IoT device can indicate its own communication type to the network device during the random access process. Accordingly, the network device can determine how to schedule the transmission of the A-IoT device in the future based on the communication type of the A-IoT device, thereby improving the transmission scheduling effect of the A-IoT device.

[0212] For example, if the communication type reported by the A-IoT device is an active transmission communication type, the subsequent network device (such as a base station) can configure periodic uplink resources for the A-IoT device.

[0213] In some embodiments, the above-mentioned A-IoT device indicates the communication type of the A-IoT device to the network device during the process of accessing and transmitting with the network device, including: indicating the communication type of the A-IoT device to the network device through a random access message in the random access process.

[0214] Accordingly, the network device obtains the communication type of the A-IoT device indicated by the A-IoT device during the access and transmission process with the network device, including: the network device obtains the communication type of the A-IoT device indicated by the random access message of the A-IoT device during the random access process.

[0215] In the above-mentioned embodiment of the present application, the A-IoT device can report its own communication type to the network device through a random access message during the random access process, so that the network device can be notified of its own communication type in a timely manner during the access process, so that the subsequent network device can perform subsequent transmission with the A-IoT device as soon as possible based on the communication type of the A-IoT device, thereby improving the transmission efficiency between the A-IoT device and the network device.

[0216] In some embodiments, the communication type of the A-IoT device is indicated by information carried in the random access message; and / or, the communication type of the A-IoT device is associated with identification information of the logical channel of the random access message.

[0217] In the above embodiment of the present application, when the A-IoT device reports its communication type to the network device through a random access message, the communication type of the above A-IoT device can be directly indicated by the information in the random access message. For example, the above random access message can carry a communication type indication information, and the communication type indication information can directly indicate the communication type of the A-IoT device.

[0218] For example, the above-mentioned communication type indication information is 1 bit. When the communication type indication information is 0, it indicates that the communication type of the A-IoT device is the backscatter communication type. When the communication type indication information is 1, it indicates that the communication type of the A-IoT device is the active transmission communication type. Alternatively, when the communication type indication information is 1, it indicates that the communication type of the A-IoT device is the backscatter communication type. When the communication type indication information is 0, it indicates that the communication type of the A-IoT device is the active transmission communication type.

[0219] In the above-mentioned embodiment of the present application, when the A-IoT device reports its own communication type to the network device through a random access message, the communication type of the above-mentioned A-IoT device can also be implicitly indicated through the random access message. For example, the A-IoT device selects the corresponding logical channel to send the random access message according to its own communication type. Correspondingly, the network device identifies the communication type of the A-IoT device based on the identification information of the logical channel of the random access message sent by the A-IoT device.

[0220] For example, when the communication type of the A-IoT device is a backscatter communication type, the A-IoT device selects the logical channel of identification information 1 to send a random access message. Accordingly, the network device determines that the identification information of the logical channel of the random access message is identification information 1, and determines that the communication type of the A-IoT device is a backscatter communication type; for another example, when the communication type of the A-IoT device is an active transmission communication type, the A-IoT device selects the logical channel of identification information 2 to send a random access message. Accordingly, the network device determines that the identification information of the logical channel of the random access message is identification information 2, and determines that the communication type of the A-IoT device is an active transmission communication type.

[0221] Through the above-mentioned embodiments of the present application, the A-IoT device can directly indicate the communication type of the A-IoT device through the information carried in the random access message. The indication method is simple and direct, and the indication efficiency is high. Alternatively, the A-IoT device can also indirectly indicate the communication type of the A-IoT device through the identification information of the logical channel of the random access message. There is no need to carry additional new information in the random access message, and the compatibility is high.

[0222] The solutions in the embodiments shown in Figures 6 to 10 above are introduced below through Examples 1 to 4.

[0223] Example 1: Different uplink frequency domain transmission resources are used for different types of A-IoT devices.

[0224] Taking the network device as a base station / cell and the A-IoT device as a UE as an example, the implementation process of the first embodiment can be as follows:

[0225] After receiving the paging message / query message / polling message / inventory request message sent by the network, the UE selects uplink resources for access transmission based on the UE's communication type.

[0226] A) For backscatter communication type UE:

[0227] 1) Initiating random access using the first uplink frequency domain resource;

[0228] 2) The first uplink frequency domain resource can be a single carrier or multiple carriers. When there are multiple carriers, the UE can randomly select a carrier or select a carrier using a specific method, such as performing a modulo operation on the number of carriers using the device ID or other device identifier, and selecting the corresponding carrier based on the modulo result. Furthermore, a weight factor can be introduced for multiple carriers, and the UE can randomly select a carrier based on the weight factor;

[0229] 3) The first uplink frequency domain resource is obtained through system message broadcast (for example, carrier wave information that the current cell supports backscatter communication), or obtained through the above-mentioned paging message / Query message / polling message / inventory request message (for example, the full set or subset of carrier wave information that the current cell supports backscatter communication).

[0230] B) For UEs that actively transmit communications:

[0231] 1) Initiate random access using the second uplink frequency domain resource;

[0232] 2) The second uplink frequency domain resource can be a single carrier or multiple carriers. When there are multiple carriers, the UE can randomly select a carrier or select a carrier using a specific method, such as using the device ID or other device identifier to perform a modulo operation on the number of carriers and selecting the corresponding carrier based on the modulo result. Furthermore, a weight factor can be introduced for multiple carriers, and the UE can randomly select a carrier based on the weight factor;

[0233] 3) The second uplink frequency domain resources are obtained through system message broadcast (for example, the random access resources configured by the current cell for the actively transmitting communication UE), or obtained through paging message / Query message / polling message / inventory request message (for example, the random access resources configured for the actively transmitting communication UE in this inventory are completed).

[0234] The first uplink frequency domain resource and the second uplink frequency domain resource do not overlap in the frequency domain.

[0235] The beneficial effects of Example 1 include: introducing different uplink frequency domain resources for backscatter communication and active transmission communication configured by the network, which helps reduce uplink interference between the two types of A-IoT devices and improve access success rate. Secondly, it helps the base station identify the communication type of the A-IoT device as early as possible and determine how to schedule subsequent terminal transmissions based on the terminal communication type. For example, if an A-IoT device is identified as an active transmission type, periodic uplink resources can be configured.

[0236] Example 2: Different uplink time domain transmission resources are used for different types of A-IoT devices.

[0237] Taking the network device as a base station / cell and the A-IoT device as a UE as an example, the implementation process of this embodiment can be as follows:

[0238] After receiving the paging message / query message / polling message / inventory request message sent by the network, the UE selects uplink resources for access transmission based on the UE's communication type.

[0239] A) For backscatter communication type terminals:

[0240] 1) Initiating random access using the first uplink resource;

[0241] 2) The first uplink resource includes multiple transmission opportunities in the time domain;

[0242] 3) The above-mentioned first uplink resources are obtained through system message broadcast (for example, the access resources configured by the current cell for backscatter communication type terminals), or through the above-mentioned paging message / Query message / polling message / inventory request message (for example, the full set or subset of access resources configured by the current cell for backscatter communication type terminals).

[0243] B) For terminals that actively transmit communications:

[0244] 1) Using the second uplink resource to initiate random access;

[0245] 2) The second uplink resource includes multiple transmission opportunities in the time domain;

[0246] 3) The above-mentioned second uplink resources are obtained through system message broadcast (for example, the access resources configured by the current cell for actively transmitting communication type terminals), or obtained through the above-mentioned paging message / Query message / polling message / inventory request message (for example, the full set or subset of access resources configured by the current cell for actively transmitting communication type terminals).

[0247] The first uplink resource and the second uplink resource do not overlap in the time domain, and may belong to the same carrier or different carriers in the frequency domain.

[0248] The beneficial effects of Example 2 include: introducing different uplink time domain resources configured by the network for backscatter communication and active transmission communication, which helps the base station identify the communication type of the A-IoT device as early as possible, and decides how to schedule the terminal transmission subsequently according to the communication type of the A-IoT device. For example, if an A-IoT device is identified as an active transmission type, periodic uplink resources can be configured.

[0249] Example 3: Use different code domain transmission resources for different types of A-IoT terminals.

[0250] Taking the network device as a base station / cell and the A-IoT device as a UE as an example, the implementation process of this embodiment can be as follows:

[0251] After receiving the paging message / query message / polling message / inventory request message sent by the network, the UE selects uplink resources for access transmission based on the UE's communication type.

[0252] A) For backscatter communication type terminals:

[0253] 1) Initiating random access using the first uplink resource;

[0254] 2) The first uplink resource includes multiple random access preambles;

[0255] 3) The above-mentioned first uplink resource is obtained through system message broadcast (for example, the random access preamble code configured by the current cell for the backscatter communication type terminal), or obtained through the above-mentioned paging message / Query message / polling message / inventory request message (for example, the full set or subset of the random access preamble code configured by the current cell for the backscatter communication type terminal).

[0256] B) For terminals that actively transmit communications:

[0257] 1) Initiate random access using the second uplink frequency domain resource;

[0258] 2) The second uplink resource includes multiple random access preamble codes;

[0259] 3) The above-mentioned second uplink resource is obtained through system message broadcast (for example, the random access preamble code configured by the current cell to the actively transmitting communication type terminal), or obtained through the above-mentioned paging message / Query message / polling message / inventory request message (for example, the full set or subset of the random access preamble code configured by the current cell to the actively transmitting communication type terminal).

[0260] The first uplink resource and the second uplink resource have no overlap in the random access preamble code set, may belong to the same carrier or different carriers in the frequency domain, and may belong to the same or different transmission timings in the time domain.

[0261] The beneficial effects of Example 3 include: introducing different preamble resources configured by the network for backscatter communication and active transmission communication, which helps the base station identify the communication type of the A-IoT device as early as possible, and decides how to schedule the terminal transmission subsequently according to the communication type of the A-IoT device. For example, if an A-IoT device of the active transmission type is identified, periodic uplink resources can be configured.

[0262] Example 4: During the random access process, the A-IoT device indicates the communication type to the network device.

[0263] Taking the network device as a base station / cell and the A-IoT device as a UE as an example, the implementation process of this embodiment can be as follows:

[0264] After receiving the paging message / query message / polling message / inventory request message sent by the network, the UE uses uplink resources for random access. During the random access process, the UE indicates its communication type, such as backscatter communication or active transmission communication.

[0265] A) It can be indicated by the first message Msg1 in the random access process, for example, before / after the preamble, for example, 1 bit, 1 indicates backscatter communication, and 0 indicates active transmission communication.

[0266] B) It can be indicated by the third message Msg3 in the random access process, such as a displayed 1-bit indication, or by a logical channel ID (LCID), for example, LCID xxxx indicates backscatter communication, and LCID yyyy indicates active transmission communication.

[0267] C) It can be indicated by the fifth message Msg5 in the random access process, for example, a displayed 1-bit indication.

[0268] The beneficial effects of Example 4 include: the A-IoT device indicates its communication type during the random access process, which helps the base station decide how to schedule terminal transmissions based on the communication type of the A-IoT device. For example, if an A-IoT device is identified as an active transmission type, periodic uplink resources can be configured.

[0269] The above-mentioned embodiment of the present application discloses a method for uplink transmission of an A-IoT device, which uses different time domain / frequency domain / code domain transmission resources for A-IoT devices of different communication types, and indicates the backscatter communication type / active transmission communication type of the A-IoT device during the random access process.
