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. Among them, when the A-IoT device sends a response information to the terminal and/or network device, it can send the response information in a backscatter working mode or it can send the response information in an active sending working mode. 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). After that, 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 and other methods, and then backscatter the modulated electromagnetic wave carrying the information to the terminal and/or network device, thereby realizing backscatter communications (Backscatter Communications), wherein the modulation mode of the A-IoT device during backscatter communications may include multiple, for example, may include amplitude shift keying (Amplitude Shift Keying, ASK), frequency shift keying (Frequency-shift keying, FSK), phase shift keying (phase-shift keying, PSK), etc. Optionally, the above-mentioned "active transmission working mode" can be understood as: actively generating signals and actively sending signals without CW signal stimulation, wherein the A-IoT device can actively generate signals and actively send signals based on its stored energy, and the energy stored in the A-IoT device can be the energy that the terminal and/or network device pre-charges the A-IoT device. From the above content, it can be seen that the "backscattering working mode" requires the A-IoT device to send CW signals in real time, while the "active transmission working mode" does not need to send CW signals to the A-IoT device in real time, and only needs to charge the A-IoT device in advance.

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 have different corresponding capabilities.

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 A-IoT device A, the energy for monitoring downlink signals also needs to be provided by external signals. Optionally, when the terminal and/or network device sends a downlink signal to A-IoT device A, the downlink signal power received by A-IoT device A needs to meet a certain power threshold (or called "activation power threshold") to activate A-IoT device A and provide A-IoT device A with sufficient energy to detect downlink signals.

Optionally, the 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.

Optionally, the A-IoT device C has energy storage capability and can independently generate and send signals. For example, the A-IoT device C can have a radio frequency (RF) module that actively sends signals. Optionally, the A-IoT device C can use the stored energy to independently generate and send 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 large.

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 the network device and/or the terminal according to the embodiment of the present disclosure. Optionally, as shown in Figure 1B, the A-IoT device and the network device (such as a base station (BS)) can directly receive and send data.

Optionally, as shown in FIG1C , the A-IoT device and the network device (such as a base station (BS)) can indirectly receive and send data through an intermediate node, wherein the intermediate node can be, for example, a relay, an integrated access backhaul (IAB) device, a terminal, or a repeater.

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, and the assisting node can be, for example, a relay, an IAB device, a terminal, or a repeater.

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

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

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. At present, when the A-IoT device triggers a random access process and/or sends an uplink to the network device, it usually generates a random number based on the Q value first, and decreases the random number per 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 a random access process and/or send an uplink is also inflexible.

FIG2A is an interactive schematic diagram of 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, which is used in a communication system 100, and the method includes:

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 a first random number.

Optionally, in some embodiments, the first parameter may be, for example, Q, and Q 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 which case the value range of the first random number is between [0, 100].

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.

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 identities. 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.

Optionally, when the first device decrements the first random number, it may be by subtracting a fixed value from the first random number. The fixed value may be a positive number, for example, may be 1.

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.

Optionally, the first value may be 0, for example.

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

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 the first device to communicate with the network device through the first channel. Therefore, after the first device determines the first parameter, it can communicate with the network device through the first channel based on the first parameter, ensuring that the first device can successfully communicate with the network device and ensuring the communication stability of the first device.

The following is an exemplary introduction to the above method.

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

a) Low-power devices are Ambient IoT devices;

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

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

a) As an embodiment, the random access parameter is a value range of a random number generated by a 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;

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

in:

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

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

The low-power device generates a random number (for example, in the range of 0-1) and compares it with the probability. If it is a low-power device within the specified probability range, random access can be initiated;

draw a random number 'rand' uniformly distributed in the range:0≤rand<1，if 'rand' is lower than the value indicated by BarringFactor: no random access is initiated, and continue to try after the barring timer specified by the network.

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;

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); (or all types may use a set of parameters without subdivision)

b) As an embodiment, low-power devices can be distinguished according to access identities. For example, when the devices leave the factory, they are set to different access identities.

c) As an embodiment, the services performed by the low-power device can be differentiated according to the access category, for example, different service types such as inventory and positioning can be set as different access categories;

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

Note: Working mode 1 and working mode 2 can work at the same time, that is, the device first decides whether to initiate random access according to working mode 2, and then uses working mode 1 to generate random numbers to wait for the channel;

4. Based on 1, the base station can instruct the low-power device to perform random access without contention;

a) As an embodiment, the specified random number may be a special code point (such as 0); (for the convenience of the agent to understand, the value of 0 indicates that the low-power device will access immediately, that is, there is no contention);

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;

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

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.
