[0270] Optionally, in some embodiments, the A-IoT device may send signaling and / or data based on backscatter. Among them, for A-IoT devices based on backscatter, there is usually a need for an energy source (continuous wave node, CW node) that provides continuous electromagnetic waves (continuous wave, CW) to provide the A-IoT device with 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.

[0271] 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.

[0272] 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.

[0273] Optionally, there are multiple different types of the above-mentioned A-IoT devices, and different types of A-IoT devices correspond to different capabilities.

Type 1 and Type 2a A-IoT devices are passive devices, while Type 2b A-IoT devices are active devices. 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.

[0275] 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.

[0276] Optionally, as shown in FIG1B , data can be directly received and sent between an A-IoT device (ie, the Ambient IoT device in FIG1B ) and a network device (eg, a base station (BS)).

[0277] 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.

[0278] 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.

[0279] 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.

[0280] 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.

[0281] Optionally, in some embodiments, in the communication architecture shown in Figures 1B-1F, to ensure successful communication between the A-IoT device and the aforementioned network devices, terminals, auxiliary nodes, or intermediate nodes, it is necessary to clearly define the operating hours of the A-IoT device during communication transmission so that when the network device configures resources for the A-IoT device, the configured resources can satisfy the operating hours of the A-IoT device. However, there is currently no clear solution to the problems of "how to determine the operating hours of the A-IoT device, and how to configure and / or notify the operating hours."

[0282] Based on this, the present disclosure provides a communication method for solving the above problems.

[0283] 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:

[0284] Step 2101: The first device and / or the second device determines a first time value corresponding to the second device.

[0285] 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 IoT device. In some embodiments, the second device may be the A-IoT device described in the previous embodiment of FIG. 2A. In some embodiments, the second device may also be referred to as a low-power device, a low-power environmental IoT device, an A-IoT device, an A-IoT UE, an A-IoT terminal, an A-IoT Tag, etc., which is not specifically limited in this disclosure. In addition, the relevant introduction to the A-IoT device has been described in detail in the previous embodiment of FIG. 2A and will not be repeated here. Furthermore, in some embodiments, the first device may be at least one of the network device, terminal, intermediate node, and auxiliary node shown in the aforementioned FIG. 1B to FIG. 1F. Optionally, in some embodiments, the first device may be referred to as an A-IoT network device or other name, which is not specifically limited in this disclosure.

[0286] Optionally, the first time value may be the operating time required for the second device to communicate. The measurement unit of the first time value may be, for example, an absolute time unit and / or a relative time unit. Optionally, the absolute time unit may be, for example, hours, minutes, seconds, milliseconds, microseconds, nanoseconds, etc. For example, the absolute time unit may be 500 milliseconds. The relative time unit may be, for example, a radio frame, a radio subframe, a time slot, a time domain symbol, etc. For example, the relative time unit may be 100 time slots.

[0287] Optionally, different second devices may respectively correspond to first time values, and different types of second devices may correspond to the same or different first time values, wherein the type of the second device may include at least one of type 1, type 2a, type 2b, and type 2c. For a detailed introduction to "type 1, type 2a, type 2b, and type 2c", please refer to the description before the embodiment of Figure 2A.

[0288] Optionally, in some embodiments, the first time value corresponding to each second device may be set (eg, burned) to the second device when the second device leaves the factory; or, the first time values ​​corresponding to different second devices may be agreed upon by protocol.

[0289] Based on this, in some embodiments, when the above-mentioned second device determines the first time value corresponding to the second device, it can be determined based on a protocol agreement, or it can be determined directly based on the factory settings of the second device, or it can receive the first time value corresponding to the second device configured by the network device.

[0290] It should be noted that in some embodiments, if the first time value corresponding to the second device is set on the second device when leaving the factory, the second device can also report the first time value corresponding to the second device to the first device, so that the first device can know the first time value corresponding to the second device, and then schedule the communication transmission of the second device based on the first time value corresponding to the second device, so that the communication transmission scheduled by the first device for the second device meets the working hours of the second device, thereby ensuring that the second device can normally perform its communication transmission with the first device, and ensure the smooth execution of communication between the first device and the second device.

[0291] In some embodiments, the first time value of the factory settings corresponding to the second device may be read by the first device when the second device registers with the network, or the second device may report the first time value of the factory settings corresponding to the second device to the first device when the second device first joins the network, or the second device may report the first time value of the factory settings corresponding to the second device to the first device when receiving the first request sent by the first device to query the first time value.

[0292] And, based on the above content, in some embodiments, when the above-mentioned first device determines the first time value corresponding to at least one second device, it can be determined based on a protocol agreement, or the first time value corresponding to the second device according to the factory settings can be obtained from the second device. For example, the first device can read the first time value corresponding to the second device according to the factory settings from the second device when the second device registers the network; or the first device can receive the first time value corresponding to the second device according to the factory settings reported by the second device to the first device when the second device first joins the network; or the first device can send a first request for querying the first time value to the second device, and when the second device receives the first request, the second device can report the first time value corresponding to the second device according to the factory settings to the first device. Optionally, in other embodiments, the first device can also use other methods to determine the first time value corresponding to the second device. For example, the first device can receive the first time value corresponding to the second device configured by the server. Also, in some embodiments, after the first device determines the first time value, if the first time value is invisible to the second device, for example, if the first device determines the first time value corresponding to the second device based on the configuration of the server, the first device can also configure the first time value corresponding to the second device to the second device.

[0293] The specific concept of the above-mentioned "first time value" is introduced in detail below.

[0294] In some embodiments, the first time value may be used to indicate at least one of the following:

[0295] the time required for the communication operation during the communication process of the second device;
