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

In this case, the interfaces between or within the access network devices involved in the embodiments of the present disclosure can be transformed into internal interfaces of the Open RAN, and the processes and information interactions between these internal interfaces can be implemented through software or programs.

[0165] In some embodiments, the access network device can be composed of a centralized unit (CU) and a distributed unit (DU), where the CU can also be called a control unit. The CU-DU structure can be used to split the protocol layer of the access network device, with the functions of some protocol layers centrally controlled by the CU, and the functions of the remaining part or all of the protocol layers distributed in the DU, which is centrally controlled by the CU, but is not limited to this.

[0166] In some embodiments, the core network device may be a device including one or more network elements, or may be multiple devices or a group of devices, each including all or part of one or more network elements. The network element may be virtual or physical. The core network, for example, includes at least one of an Evolved Packet Core (EPC), a 5G Core Network (5GCN), and a Next Generation Core (NGC). Alternatively, the core network device may also be a location management function network element. Exemplarily, the location management function network element includes a location server (location server), which may be implemented as any one of the following: Location Management Function (LMF), Enhanced Serving Mobile Location Centre (E-SMLC), Secure User Plane Location (SUPL), and Secure User Plane Location Platform (SUPLLP).

[0167] 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.

[0168] The following embodiments of the present disclosure may be applied to the communication system 100 shown in FIG1A , or a portion thereof, but are not limited thereto. The entities shown in FIG1A are illustrative only. The communication system may include all or part of the entities shown in FIG1A , or may include other entities other than those shown in FIG1A . The number and form of the entities may be arbitrary. The connection relationship between the entities is illustrative only. The entities may be connected or disconnected, and the connection may be in any manner, including direct or indirect, wired or wireless.

[0169] 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).

[0170] Optionally, the above-mentioned device that collects energy and communicates based on the collected energy can be called an ambient Internet of Things (A-IoT) device, or a low-power device. Optionally, the A-IoT device can communicate with the terminal and / or network device based on the energy collected from the outside world. Specifically, in some embodiments, the terminal and / or network device can send a downlink signal to the A-IoT device. After the A-IoT device receives the downlink signal, it can send corresponding response information to the terminal and / or network device or perform corresponding operations. When the A-IoT device sends a response message to the terminal and / or network device, it can use a backscatter working mode to send the response message or it can use an active sending working mode to send the response message. Optionally, the above-mentioned "backscatter working mode" can be, for example: the terminal and / or network device sends an electromagnetic wave (continuous wave, CW) signal to the A-IoT device, and the A-IoT device obtains energy after receiving the CW signal (such as obtaining energy to activate the receiving and processing module inside the A-IoT device). Afterwards, the internal circuit of the A-IoT device can modulate the information to be sent based on the incident electromagnetic wave (i.e., the CW signal) through load impedance modulation, etc., and then backscatter the modulated electromagnetic wave carrying the information to the terminal and / or network device, thereby realizing backscatter communication (Backscatter Communications). The modulation mode of the A-IoT device during backscatter communication may include multiple types, for example, amplitude shift keying (ASK), frequency shift keying (FSK), phase shift keying (PSK), etc. Optionally, the aforementioned "active transmission working mode" can be understood, for example, as actively generating and transmitting signals without the need for CW signal excitation, wherein the A-IoT device can actively generate and transmit signals based on its stored energy, and the energy stored in the A-IoT device can be energy pre-charged for the A-IoT device by the terminal and / or network device. As can be seen from the above, the "backscattering working mode" requires the real-time transmission of CW signals to the A-IoT device, while the "active transmission working mode" does not require the real-time transmission of CW signals to the A-IoT device, and only requires the A-IoT device to be pre-charged.

[0171] Optionally, the above-mentioned A-IoT devices may be of different types, for example, including A-IoT device A, A-IoT device B, and A-IoT device C. Different types of A-IoT devices may have different corresponding capabilities.

[0172] Optionally, the above-mentioned A-IoT device A has no energy storage capability, does not support energy storage, and cannot perform independent signal generation or amplification, but needs to use a backscattering working mode to send an uplink signal (such as the aforementioned response information) to the terminal and / or network device, which has the lowest complexity and cost and consumes very little power. In addition, for the A-IoT device A, the energy for monitoring the downlink signal also needs to be provided by an external signal. Optionally, when the terminal and / or network device sends a downlink signal to the A-IoT device A, the downlink signal power received by the A-IoT device A needs to meet a certain power threshold (or called an "activation power threshold") to activate the A-IoT device A and provide the A-IoT device A with sufficient energy to detect the downlink signal.

[0173] Optionally, the above-mentioned A-IoT device B has energy storage capability but cannot generate independent signals. It can communicate using a backscattering working mode and can use the stored energy to amplify the reflected signal.

[0174] Optionally, the A-IoT device C has energy storage capabilities and can independently generate and transmit signals. For example, the A-IoT device C can include a radio frequency (RF) module for active signal transmission. Alternatively, the A-IoT device C can use stored energy to independently generate and transmit signals to achieve active transmission. However, the complexity and cost of the A-IoT device C are relatively high, and the power consumption is relatively high.

[0175] Optionally, the above-mentioned A-IoT device can be applied to a variety of different communication architectures in the communication system, wherein Figures 1B-1F are schematic diagrams of the architecture when the A-IoT device communicates with network devices and / or terminals according to embodiments of the present disclosure. Optionally, as shown in Figure 1B, data can be directly received and sent between the A-IoT device and the network device (such as a base station (BS)).

[0176] Optionally, as shown in FIG1C , data can be received and sent indirectly between the A-IoT device and the network device (such as a base station (BS)) through an intermediate node, where the intermediate node can be, for example, a relay, an integrated access backhaul (IAB) device, a terminal, or a repeater.

[0177] Optionally, as shown in FIG1D , uplink data can be directly transmitted between the A-IoT device and the network device (such as a base station (BS)), and downlink data can be indirectly transmitted between the A-IoT device and the network device (such as a base station (BS)) through an assisting node, which can be, for example, a relay, an IAB device, a terminal, or a repeater.

[0178] Optionally, as shown in FIG1E , downlink data can be directly transmitted between the A-IoT device and the network device (such as a base station (BS)), and uplink data can be indirectly transmitted between the A-IoT device and the network device (such as a base station (BS)) through an assisting node.

[0179] Optionally, as shown in FIG1F , data can be directly received and sent between the A-IoT device and the terminal (or user equipment (UE)). The terminal can be responsible for collecting data from the A-IoT device and forwarding the collected data to the network device.

[0180] Optionally, for the communication architecture shown in Figures 1B, 1D, and 1E above, the A-IoT device usually needs to trigger a random access process to access the base station, or it also needs to send an uplink to the network device. Currently, when the A-IoT device triggers a random access process and / or sends an uplink to the network device, it usually first generates a random number based on the Q value, and decreases the random number over the unit time. When the random number decreases to 0, the random access process can be triggered to the network device and / or an uplink can be sent to the network device. However, the current Q value is agreed upon by the protocol and is not flexible, which results in the method for the A-IoT device to trigger the random access process and / or send an uplink being inflexible.

[0181] FIG2A is an interactive diagram illustrating a determination method according to an embodiment of the present disclosure. As shown in FIG2A , the embodiment of the present disclosure relates to a determination method for a communication system 100, the method comprising:

[0182] Step 2101: The network device configures a first parameter, where the first parameter is used to indicate a value range of the first random number when the first device generates the first random number.

[0183] Optionally, the network device may configure the first parameter to the first device, and the first device may receive the first parameter. Optionally, the first device may be a device that communicates based on energy collected from the outside world.

[0185] Optionally, in the embodiment of FIG2A , the first parameter is specifically used to indicate a value range of the first random number when the first device generates the first random number. Optionally, the first random number can be used to indicate a first duration, which can be a waiting duration when the first device sends an uplink message to the network device, and / or, the first duration can be a waiting duration when the first device attempts random access. Optionally, the first duration can be, for example, called a barring timer.

[0186] Optionally, in some embodiments, the first parameter may be, for example, Q, which may be used to indicate that the value range of the first random number is between [0, 2 Q Alternatively, the first parameter may be, for example, the maximum value that the first random number can take, for example, the first parameter may be 100. In this case, the value range of the first random number is between [0, 100].

[0187] Optionally, in some embodiments, when the network device configures the first parameter, it can be configured based on the device type of the first device. For example, different first parameters can be configured for different types of first devices, where the different types of first devices can be, for example, A-IoT device A, A-IoT device B, and A-IoT device C in the previous description of the embodiment of Figure 2A.

[0188] Optionally, in some other embodiments, the network device may configure the first parameter based on the access identity of the first device. For example, different first parameters may be configured for first devices with different access identity. Optionally, the access identity may be set for the first device when the first device leaves the factory. Optionally, the network device may obtain the access identity of the first device from the core network element and / or the first device in advance, so that the network device configures the corresponding first parameter for the first device based on the obtained access identity.

[0189] Optionally, in some further embodiments, the network device may configure the first parameter based on the service access type (Access category) of the first device. For example, different first parameters may be configured for first devices of different service access types. Optionally, the service access type may include, for example, an inventory service, a positioning service, and other different service access types. Optionally, the network device may pre-acquire the service access type of the first device from a core network element and / or the first device, so that the network device configures the corresponding first parameter for the first device based on the acquired service access type.

[0190] Optionally, in some embodiments, all types of first devices may share the same first parameter, or all first devices of access identification may share the same first parameter, or all first devices of service access types may share the same first parameter.

In the method provided in the embodiments of the present disclosure, the first device may use a variety of different methods (e.g., protocol pre-definition and / or network device configuration) to determine the first parameter, thereby increasing flexibility in determining the first parameter.

[0193] Also, for a detailed introduction to the first parameter, please refer to the above embodiment description.

[0194] Step 2103: The first device generates a first random number based on the first parameter.

[0195] Optionally, the first random number generated by the first device should be within the value range indicated by the first parameter. The specific method for the first device to generate the first random number can be referred to the prior art description and will not be repeated here.

[0196] Step 2104: Every time a unit of time passes, the first device decrements the first random number.

[0197] Optionally, the unit time may include any of the following:

[0198] milliseconds ms;

[0199] The length of a time domain unit defined for the first channel. Optionally, the time domain unit may include any one of a frame, a symbol, and a time slot.

[0200] Optionally, when the first device decrements the first random number, it may subtract a fixed value from the first random number. The fixed value may be a positive number, for example, 1.

[0201] Step 2105: The first random number decreases to a first value, and the first device attempts random access and / or performs uplink transmission to the network device through the first channel.

[0202] Optionally, the first value may be 0, for example.

[0203] Optionally, in some embodiments, if the first device has not yet determined to perform random access, the first device may attempt random access when the first random number decreases to the first value; if the first device has currently determined to perform random access, the first device may send a random access message to the network device when the first random number decreases to the first value.

[0204] In the above embodiment, a method for a first device to determine a first parameter is provided, so that the first device can successfully determine the first parameter. The first parameter can be used for communication between the first device and a network device via a first channel. Thus, after the first device determines the first parameter, it can communicate with the network device via the first channel based on the first parameter, thereby ensuring that the first device can successfully communicate with the network device and maintaining communication stability of the first device.

[0350] The following is an exemplary introduction to the above method.

[0351] 1. The base station provides access channel configuration information for low-power devices;

[0352] a) Low-power devices are Ambient IoT devices;

[0353] b) The working channel has not yet been defined and can be interpreted as a collection of physical layer air interface resources, such as a collection of time / frequency / code / space resources.

[0354] 2. Based on 1, the base station configures random access parameters for the currently activated working channel;

[0355] a) As an embodiment, the random access parameter is a value range of a random number generated by the low-power device, such as Q, or a numerical value, such as 100; and is used for the low-power device to generate a random number within the range;

[0356] b) As an embodiment, working mode 1: the low-power device generates a random number according to Q, and decreases it over the unit time. When it decreases to 0, it can be sent;

[0357] in:

[0358] The unit time can be: ms or compared to the frame length, symbol length, etc. of the working channel;

[0359] c) As an embodiment, in working mode 2, the random access parameter is a probability (barring factor) of random access by a low-power device, for example, 30%; and is used for the low-power device to generate a random number within the range;

[0360] The low-power device generates a random number (e.g., in the range of 0-1) and compares it with the probability. If the low-power device is within the specified probability range, it can initiate random access;

[0361] Draw a random number 'rand' uniformly distributed in the range: 0≤rand<1. If 'rand' is lower than the value indicated by BarringFactor: then no random access is initiated, and attempts are continued after the barring timer specified by the network.

[0362] 3. Based on 2, for working mode 2, the low-power device can obtain random access parameters from the base station or from the protocol agreement;

[0363] a) As an embodiment, the base station may provide the same or different random access parameter values, such as barring factor / barring timer, for different types of low-power devices (device A, device B, device C). (Alternatively, all types may use a single set of parameters without further subdivision.)

[0364] b) As an embodiment, low-power devices can be distinguished according to access identities. For example, when a device leaves the factory, it is set to a different access identity.

[0365] c) As an embodiment, the services performed by the low-power device can be differentiated according to access categories. For example, different service types such as inventory and positioning can be set as different access categories.

[0366] d) Different barring factors / barring timers can be set for different access identifiers / access categories

[0367] Note: Working mode 1 and working mode 2 can work simultaneously. That is, the device first determines whether to initiate random access according to working mode 2, and then uses working mode 1 to generate a random number and wait for the channel.

[0368] 4. Based on 1, the base station can instruct the low-power device to perform contention-free random access;

[0369] a) As an embodiment, the designated random number may be a special code point (e.g., 0); (for ease of understanding by the agent, a value of 0 indicates that the low-power device is to be accessed immediately, i.e., in a contention-free manner);

[0370] b) As an embodiment, the base station may carry a specific random number, such as 0, in a paging message for a low-power device, so that the low-power device can initiate access immediately after receiving the paging message;

[0371] 5. Based on 1, the base station can instruct the low-power device to prohibit random access;

[0372] As an embodiment, the specified random number may be an infinite value or a special code point (eg, a barring factor of 0); that is, low-power devices are not allowed to perform random access.

For example, an apparatus is provided, comprising units or modules for implementing each step performed by a terminal in any of the above methods.

In addition, it can also be a hardware circuit designed for artificial intelligence, which can be understood as an ASIC, such as a neural network processing unit (NPU), a tensor processing unit (TPU), a deep learning processing unit (DPU), etc.
