Optionally, the aforementioned A-IoT device may also be referred to as, for example, an A-IoT UE, an A-IoT terminal, an A-IoT Tag, etc., and the A-IoT device may collect energy from the outside world to supply normal uplink and downlink transmission. For example, the A-IoT device may collect ambient energy and/or artificial energy to supply normal uplink and downlink transmission. Optionally, the ambient energy may include, for example, natural energy such as solar energy, wind energy, and nuclear energy, and the artificial energy may include, for example, energy such as electromagnetic waves transmitted by artificial devices.

Optionally, in some embodiments, the A-IoT device may send signaling and/or data based on backscatter. Specifically, for an A-IoT device based on backscatter, there is usually a need for an energy source (continuous wave node, CW node) that provides a continuous electromagnetic wave (continuous wave, CW) to provide the A-IoT device with a CW for reflection. In addition, the A-IoT device can receive the CW sent by the energy source, and the CW can be used to charge the A-IoT device to activate the internal receiving and processing module to start working, so that the A-IoT device can encode and modulate the signaling and/or data to be sent, and load the signaling and/or data to be sent onto the reflected wave and send it out, thereby realizing backscatter communication.

Optionally, the energy source may be a separate node, or a base station communicating with the A-IoT device, or an intermediate node (such as a terminal) communicating with the A-IoT device. Optionally, the frequency of the electromagnetic waves emitted by the energy source may be a constant amplitude, and the transmission frequency used by the A-IoT device when reflecting the electromagnetic waves may be the same as the frequency of the electromagnetic waves emitted by the energy source, or the transmission frequency used by the A-IoT device when reflecting the electromagnetic waves may be offset from the frequency of the electromagnetic waves emitted by the energy source, wherein the magnitude of the offset value is related to the hardware characteristics of the A-IoT device. Optionally, the offset value may be a fixed value, or the offset value may be dynamically adjusted.

Optionally, the A-IoT device may also send signaling and/or data in an active manner. Optionally, the "active transmission" may be understood as, for example, actively generating and sending signals without the need for CW signal excitation. The A-IoT device may actively generate and send signals based on its stored energy, and the energy stored in the A-IoT device may be energy that has been pre-charged for the A-IoT device.

Optionally, there are multiple different types of the above-mentioned A-IoT devices, and different types of A-IoT devices correspond to different capabilities.

Optionally, the device types of A-IoT devices may include, for example, Type 1, Type 2a, Type 2b, and Type 2c.

Optionally, Type 1 A-IoT devices operate based on backscattering, have the lowest complexity, and consume very little power. Type 2a A-IoT devices support energy storage and operate based on backscattering, and have higher complexity and power consumption than Type 1 A-IoT devices. Furthermore, Type 2a A-IoT devices have certain signal amplification capabilities, but they still maintain a relatively low level. Type 2b A-IoT devices operate based on active transmission, have the ability to amplify signals, and can actively transmit information. Type 2c A-IoT devices have both the ability to actively transmit information and the ability to backscatter.

Optionally, the above-mentioned A-IoT device can be applied to a variety of different communication architectures in the communication system, wherein Figures 1B to 1F are schematic diagrams of the architecture of the A-IoT device during communication according to an embodiment of the present disclosure.

Optionally, as shown in Figure 1B, data can be directly received and sent between an A-IoT device (i.e., the Ambient IoT device in Figure 1B) and a network device (such as a base station (BS)).

Optionally, as shown in FIG1C , data can be indirectly received and sent 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.

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.

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.

Optionally, as shown in Figure 1F, 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.

Optionally, in some embodiments, in the communication architecture shown in Figures 1B-1F above, when the A-IoT device communicates with the above-mentioned network device, terminal, auxiliary node or intermediate node, it is usually necessary to set a communication gap (GAP) between adjacent communication transmissions. The communication GAP can be understood as: the time when no communication is performed, that is, during the communication GAP, the A-IoT device does not communicate with the above-mentioned network device, terminal, auxiliary node or intermediate node, so that the A-IoT device has enough time to charge and perform various preparations to support the next communication transmission. However, there is currently no clear solution to the problems of "how to determine the communication GAP, and how to configure and/or notify the communication GAP so that sufficient communication GAPs can be reserved between adjacent communication transmissions of the A-IoT device."

Based on this, the present disclosure provides a communication method for solving the above problems.

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

Step 2101: The first device determines a first condition.

Optionally, the first device may be a device that communicates with the second device, and the second device may be a device that communicates based on collected energy. For example, the second device may be an environmental Internet of Things device. In some embodiments, the second device may be the A-IoT device described in the previous content of the embodiment of Figure 2A. In some embodiments, the second device may also be called a low-power device, a low-power environmental Internet of Things device, an A-IoT device, an A-IoT UE, an A-IoT terminal, an A-IoT Tag, etc., and the present disclosure does not specifically limit this. In addition, the relevant introduction to the A-IoT device has been described in detail in the previous content of the embodiment of Figure 2A and will not be repeated here. Further, in some embodiments, the first device may be at least one of the network devices, terminals, intermediate nodes, and auxiliary nodes shown in Figures 1B to 1F above. Optionally, in some embodiments, the first device may be called an A-IoT network device or other names, and the present disclosure does not specifically limit this.

Optionally, the first condition may be: a condition that a communication GAP needs to satisfy during the communication between the first device and the second device.

Optionally, the communication GAP can be understood as, for example, the time interval between different communication transmissions between the first device and the second device. In some embodiments, the measurement unit of the communication GAP can be, for example, an absolute time unit and/or a relative time unit. Optionally, the absolute time unit can be, for example, hours, minutes, seconds, milliseconds, microseconds, nanoseconds, etc., for example, the absolute time unit can be 500 milliseconds. The relative time unit can be, for example, a radio frame, a radio subframe, a time slot, a time domain symbol, etc., for example, the relative time unit can be 100 time slots.

The definition of the above-mentioned "communication GAP" is introduced in detail below.

First, the transmission from the first device to the second device may be referred to as downlink transmission, and the transmission from the second device to the first device may be referred to as uplink transmission. In some embodiments, there are multiple communication scenarios between the first device and the second device, and the definition of the communication GAP may vary in different communication scenarios.

Optionally, the communication scenario between the first device and the second device may be a first scenario, where the first scenario may be: the first device performs a downlink transmission to the second device, and the downlink transmission is used to enable the second device to perform an uplink transmission to the first device; optionally, in some embodiments, the communication transmission in the first scenario may be a communication transmission triggered by an inventory service, for example, the downlink transmission performed by the first device to the second device is used to initiate an inventory service, then after the first device performs a downlink transmission to the second device, the second device triggers the execution of the inventory service and performs an uplink transmission to the first device to report inventory-related information to the first device. Optionally, in the first scenario, the communication GAP may refer to the time interval between adjacent downlink transmissions and uplink transmissions of the first device and the second device. For example, in some embodiments, the communication GAP may include a time gap between a first position of the first signal and a second position of the second signal. Optionally, the first signal may be a signal sent by the first device to the second device. For example, the first signal may include at least one of a third signal, a fourth signal, a downlink (DL) control signal, a DL control signal, and a DL data signal (or, the DL control signal and the DL data signal may also be referred to as a DL control data signal, etc.). The third signal may, for example, be a signal for stimulating the second device to perform backscattering, and the third signal may, for example, be the CW signal described before the embodiment of FIG2A . The fourth signal may, for example, be used to charge the second device, that is, the fourth signal may be a charging signal for the second device, for example, the fourth signal may be an energy source (ES) signal. Optionally, the second signal may be a signal sent by the second device to the first device, wherein the second device may send the second signal based on backscattering, or the second device may send the second signal based on active transmission, and the second signal may, for example, include an uplink (UL) data signal. Optionally, the first position and the second position may respectively include a starting position or an ending position.

Based on the above, in some embodiments, the communication GAP may include at least one of the following:

A time GAP between a starting position at which the first device sends the third signal and a starting position at which the first device receives the UL data signal backscattered by the second device;

A time GAP between a starting position at which the first device sends the fourth signal and a starting position at which the first device receives the UL data signal backscattered by the second device;

A time GAP between an end position of the first device sending the DL control signal and a start position of the first device receiving the UL data signal backscattered by the second device;

A time GAP between an end position at which the first device sends a DL control signal and a DL data signal and a start position at which the first device receives a UL data signal backscattered by the second device;

A time GAP between a starting position at which the first device sends the third signal and a starting position at which the first device receives the UL data signal actively sent by the second device;

A time GAP between a starting position at which the first device sends the fourth signal and a starting position at which the first device receives the UL data signal actively sent by the second device;

A time GAP between the end position of the first device sending the DL control signal and the start position of the first device receiving the UL data signal actively sent by the second device;

The time GAP is between the end position where the first device sends the DL control signal and the DL data signal and the start position where the first device receives the UL data signal actively sent by the second device.

Optionally, in some other embodiments, the communication scenario between the first device and the second device may be a second scenario, and the second scenario may be: the first device performs multiple downlink transmissions to the second device. Optionally, in some embodiments, the communication transmission in the second scenario may be a communication transmission triggered by a write demand. For example, the first device will first perform a first downlink transmission to the second device, and the first downlink transmission may be used to inform the second device that the first device is about to send data on certain resources, or the first downlink transmission may be used to inform the second device that the first device is about to send data on certain resources and also carry some downlink data. Afterwards, the first device will perform a second downlink transmission to the second device, and the second downlink transmission is used for the first device to send downlink data to the second device.
