[0041] The embodiments of the present disclosure provide a communication method and apparatus, a communication device, a communication system, and a storage medium.

[0042] In a first aspect, an embodiment of the present disclosure provides a communication method, which is performed by a first device. The method includes:

[0043] Determining a first duration corresponding to at least one second device; the second device being a device that communicates based on collected energy, the first duration being the time required for the second device to collect sufficient energy to complete at least one communication transmission;

[0044] Before initiating communication transmission scheduling to at least one second device, a first operation of a first duration is performed; wherein the communication transmission scheduling is used to schedule the second device to perform communication transmission, and the first operation is used for the second device to perform energy collection.

[0045] In the above embodiment, the first device will first determine the first duration of the second device (i.e., the duration required for the second device to charge), and before the first device initiates communication transmission scheduling to the second device, the first device will first perform the first operation of the first duration, so that the second device can collect energy for the first duration, so that the second device can collect enough energy for the second device to complete at least one communication transmission. It can be seen that in the method of the present disclosure, before the first device initiates communication transmission scheduling to the second device, sufficient time will be reserved for the second device to charge, so that when the first device initiates communication transmission scheduling to the second device, the second device can have enough energy to support communication transmission, thereby ensuring the successful execution of communication transmission of the second device.

[0046] In combination with some embodiments of the first aspect, in some embodiments, the first duration is the time required for the second device to collect enough energy to complete one communication transmission; or, the first duration is the time required for the second device to collect enough energy to complete N communication transmissions, where N is a positive integer greater than 1, and N is predefined by the protocol.

[0047] In the above embodiment, the first duration is specifically defined, where the first duration can be the time required for the second device to collect enough energy to complete one communication transmission, or the first duration can be the time required for the second device to collect enough energy to complete N communication transmissions. Therefore, when the first device reserves the first duration of charging time for the second device before initiating communication transmission scheduling for the second device, it can be ensured that the charged second device can successfully complete one or N communication transmissions, thereby ensuring the stability and efficiency of the second device's communication transmission.

[0048] In conjunction with some embodiments of the first aspect, in some embodiments, the communication transmission includes at least one of the following processes:

[0049] Uplink data sending;

[0050] Backscatter transmission;

[0051] Uplink data preparation and sending;

[0061] In the above embodiment, it is clarified which specific processes the communication transmission includes, so that the charging time required to support the second device to complete the communication transmission can be accurately determined based on the specific processes included in the communication transmission. Therefore, before the first device initiates the corresponding scheduling of the communication transmission to the second device, the corresponding charging time can be accurately reserved for the second device, avoiding the problems of "the time reserved by the first device is too long, causing the second device to perform unnecessary charging operations, resulting in waste of resources; or the time reserved by the first device is too short, resulting in insufficient charging of the second device, causing communication transmission failure". Therefore, the successful execution of the communication transmission is guaranteed while avoiding waste of resources.

[0072] A first request is sent to the second device and a first duration corresponding to the second device reported by the second device is received; the first request is used to query the first duration corresponding to the second device.

[0073] In conjunction with some embodiments of the first aspect, in some embodiments, determining the first duration corresponding to at least one second device includes:

[0074] Determining a first corresponding relationship based on a protocol agreement, the first corresponding relationship being: a corresponding relationship between different communication conditions of the second device and the first duration;

[0075] determining a communication condition of the second device based on a first signal sent by the second device; wherein the first signal is sent when the second device last transmitted a communication, and / or the first signal is sent when the second device is about to run out of energy; and the first signal is predefined by a protocol;

This ensures the successful execution of communication transmission while avoiding resource waste.

[0099] In the above embodiment, the second device will first determine the first duration of the second device (i.e., the duration required for the second device to be charged), and before the first device initiates communication transmission scheduling to the second device, the second device will first perform the first operation of the first duration, so that the second device can collect energy for the first duration, so that the second device can collect enough energy for the second device to complete at least one communication transmission.

[0282] 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.

[0283] 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.

[0284] 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.

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.

[0287] 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.

[0290] 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.

[0291] 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.

[0292] 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.

[0293] Optionally, in some embodiments, the A-IoT devices described above typically need to collect energy for charging before they begin operating. However, since charging is not instantaneous, a certain amount of charging time must be reserved to ensure that the A-IoT devices have sufficient energy to perform a complete or partial transmission.

[0322] In other embodiments, the second device may determine multiple first durations based on a protocol agreement, where different first durations may apply to different types of second devices. For example, the protocol may stipulate that the first durations corresponding to a type 1 second device, a type 2a second device, a type 2b second device, and a type 2c second device are T_1, T_2a, T_2b, and T_2c, respectively.

[0323] In other embodiments, the second device may determine multiple first time durations based on the protocol agreement, wherein different first time durations may be applicable to different types of second devices. For example, the protocol may stipulate that the first time durations corresponding to the second device of type 1 and the second device of type 2 are respectively: T_1, T_2. Optionally, the above-mentioned "second device of type 1" may be understood as: a second device that communicates based on backscattering; the above-mentioned "second device of type 2" may be understood as: a second device that communicates based on active transmission. For a detailed introduction to "backscattering, active transmission", please refer to the description before the embodiment of Figure 2A. In addition, in other embodiments, the classification method of the above-mentioned second device of type 1 and the second device of type 2 may also have other forms, for example, it may be classified based on power consumption, etc., and the present disclosure does not make specific limitations on this.

[0324] In the second case, the second device autonomously determines the first duration corresponding to the second device.

[0325] Optionally, in some embodiments, the first duration corresponding to the second device will be set (such as burned) on the second device when the second device leaves the factory. Thus, the second device can independently determine the first duration corresponding to the second device based on its factory settings.

[0326] Moreover, in some embodiments, the agreement may also stipulate at least one first duration. For example, the agreement may stipulate the first durations corresponding to all second devices respectively. In this case, the first duration corresponding to the second device set on the second device at the factory should be included in the at least one first duration stipulated in the agreement.

[0327] Optionally, in some embodiments, when the first duration corresponding to the second device is set (e.g., burned) onto the second device when the second device leaves the factory, the first device will also determine the first duration corresponding to the second device from the second device. The reason why the first device determines the first duration corresponding to the second device is mainly so that after the first device knows the first duration corresponding to the second device, it can cooperate with the second device to charge the second device based on the first duration, so that the second device can have enough energy to complete at least one communication transmission before the communication transmission, thereby facilitating the second device to successfully complete the communication transmission later.

[0328] Optionally, in some embodiments, the method by which the first device determines the first duration corresponding to the second device from the second device may include at least one of the following:

[0329] When the second device registers the network, the first device reads the first duration corresponding to the second device from the second device;

[0330] When the second device accesses the network for the first time, the second device reports the first duration corresponding to the second device to the first device;

[0331] The first device sends a first request for querying a first duration to the second device, and when the second device receives the first request, the second device reports the first duration corresponding to the second device to the first device.

[0332] Optionally, it should be noted that when the first duration is set on the second device at the factory, the indication information corresponding to the first duration can be set on the first device. The indication information is used to indicate the first duration. The indication information can be, for example, an indication serial number. Since the indication serial number contains a small number of bits, its setting difficulty (such as burning difficulty) will be much less than the setting difficulty of the first duration, thereby greatly reducing the complexity of the work. In addition, when the second device reports the first duration corresponding to the second device to the first device, the second device can report the indication information corresponding to the first duration to the first device. Similarly, since the number of bits of the indication information can be small, the communication resources required to report the indication information are also small, thereby saving resource overhead.

[0333] For example, in one implementation, it is assumed that the protocol predefines four first durations, namely 500 milliseconds (ms), 1000ms, 15000ms, and 5000ms, wherein 500ms, 1000ms, 15000ms, and 5000ms are represented by indication sequence number 00, indication sequence number 01, indication sequence number 10, and indication sequence number 11, respectively. Optionally, assuming that the first duration corresponding to the type 1 second device is 500ms, the type 1 second device can be burned with "indication sequence number 00" when leaving the factory, and when the type 1 second device reports the first duration to the first device, it can also report "indication sequence number 00" to the first device, thereby greatly reducing the difficulty of burning and reducing communication resource overhead.

[0334] A third type is that the second device determines the first duration corresponding to the second device based on the communication condition of the second device.

[0335] Optionally, the second device can first determine a first corresponding relationship based on the protocol agreement, and the first corresponding relationship is: the corresponding relationship between different communication conditions of the second device and the first time length; thereafter, the second device can determine the communication conditions of the second device, and determine the first time length corresponding to the second device based on the communication conditions of the second device and the first corresponding relationship.

[0336] Optionally, the communication conditions may include at least one of the following: a channel environment, a distance between the first device and the second device, a transmission power of the second signal, and a reception power of the second signal. The second signal may be used to charge the second device, that is, the second signal may be a charging signal for the second device, for example, an energy source (ES) signal.

[0337] And, similarly, referring to the foregoing, after the second device determines the first duration corresponding to the second device, it is also necessary to enable the first device to know the first duration corresponding to the second device. Optionally, in some embodiments, when the second device determines the first duration corresponding to the second device based on the communication condition of the second device, the second device can enable the first device to know the first duration corresponding to the second device in the following manner. Specifically, the second device can send a first signal to the first device, and the first signal can be used by the first device to determine the communication condition of the second device, so that the first device can further determine the first duration corresponding to the second device based on the communication condition of the second device. The first signal can be predefined by the protocol, for example, the protocol can predefine the first signal as a reference signal. And, the first signal can be sent during the last communication transmission of the second device, and / or, when the second device has the ability to actively send, the first signal can be sent when the energy of the second device is about to run out.

[0338] Fourthly, the second device receives the first duration corresponding to the second device configured by the first device.

[0339] The above is a detailed description of “how the second device specifically determines the first duration corresponding to the second device.” The following further details “how the first device specifically determines the first duration corresponding to the second device.”

[0340] In some embodiments, the first device may determine a first duration based on a protocol agreement, wherein the first duration may be applicable to different types of second devices. Optionally, in some embodiments, the device type of the second device may include at least one of Type 1, Type 2a, Type 2b, and Type 2c. For a detailed description of "Type 1, Type 2a, Type 2b, and Type 2c," please refer to the description above of the embodiment of FIG. 2A.

[0341] In other embodiments, the first device may determine multiple first durations based on a protocol agreement, where different first durations may apply to different types of second devices. For example, the protocol may stipulate that the first durations corresponding to type 1 second devices, type 2a second devices, type 2b second devices, and type 2c second devices are T_1, T_2a, T_2b, and T_2c, respectively.

[0342] In some other embodiments, the first device may determine the first duration corresponding to the second device from the second device. In this solution, the protocol may stipulate at least one first duration. For example, the protocol may stipulate the first durations corresponding to all second devices, and the first duration determined by the first device from the second device is included in the at least one first duration stipulated in the protocol.

[0343] Optionally, the first duration corresponding to the second device at the above-mentioned second device can be set (such as burned) to the second device when the second device leaves the factory. And, when the second device registers the network, the first device can read the first duration corresponding to the second device from the second device; or, when the second device accesses the network for the first time, the second device can report the first duration corresponding to the second device to the first device; or, the first device can send a first request to the second device, and the first request can be used to query the first duration corresponding to the second device, and after the second device receives the first request, it can report the first duration corresponding to the second device to the first device. Among them, for the relevant introduction on how the second device specifically reports the first duration, please refer to the above description.

[0344] In some other embodiments, the first device may determine the first duration corresponding to the second device based on the communication condition that the second device is in. For a detailed introduction to the communication condition, please refer to the above description.

[0345] Optionally, the aforementioned method of "a first device determining a first duration corresponding to a second device based on the communication conditions of the second device" may include: the first device determining a first correspondence based on a protocol agreement, where the first correspondence may be a correspondence between different communication conditions of the second device and the first duration; and the first device determining the communication conditions of the second device based on a first signal sent by the second device, wherein a detailed description of the first signal can be found in the above embodiment. Thereafter, the first device may determine the first duration corresponding to the second device based on the communication conditions of the second device and the first correspondence.

[0346] Optionally, in some embodiments, after the first device determines the first duration corresponding to the second device, the first duration may be configured for the second device.

[0347] Step 2102: Before initiating communication transmission scheduling to at least one second device, the first device performs a first operation of a first duration.

[0348] Optionally, the above-mentioned communication transmission scheduling can be used to schedule the second device to perform communication transmission. For a detailed introduction to "communication transmission", please refer to the above-mentioned step description.

[0349] Optionally, the aforementioned “the first device performs the first operation for the first duration” may include at least one of the following:

[0350] The first device sends a second signal of a first duration to the second device, wherein the second signal can be used to charge the second device, that is, the second signal can be a charging signal for the second device, for example, the second signal can be: an ES signal;

[0351] A wait operation for a first duration is performed, where the wait operation can be understood as, for example, the first device not performing any transmission to the second device, and the second device being in an idle state, allowing the second device to collect sufficient energy from the environment to complete at least one communication transmission within the first duration. In some embodiments, the wait operation for the first duration may be performed when the first device knows that the second device is capable of collecting natural energy from the environment.

[0352] Step 2103: Before receiving the communication transmission schedule initiated by the first device to the second device, the second device performs a first operation of a first duration.

[0353] Optionally, the above-mentioned communication transmission scheduling can be used to schedule the second device to perform communication transmission. For a detailed introduction to "communication transmission", please refer to the above-mentioned step description.

[0354] Optionally, the aforementioned “the second device performs the first operation for the first duration” may include at least one of the following:

[0355] receiving a second signal of a first duration sent by the first device, and charging the second device for the first duration based on the second signal of the first duration;

[0356] Collect energy from the environment during the first duration.

[0357] Step 2104: The first device initiates communication transmission scheduling to at least one second device.

[0358] Optionally, the second device may receive a communication transmission schedule initiated by the first device.

[0359] Step 2105: The second device executes the communication transmission scheduled by the communication transmission scheduling.

[0360] In the above embodiment, the first device will first determine the first duration of the second device (i.e., the duration required for the second device to charge), and before the first device initiates communication transmission scheduling to the second device, the first device will first perform the first operation of the first duration, so that the second device can collect energy for the first duration, so that the second device can collect enough energy for the second device to complete at least one communication transmission. It can be seen that in the method of the present disclosure, before the first device initiates communication transmission scheduling to the second device, sufficient time will be reserved for the second device to charge, so that when the first device initiates communication transmission scheduling to the second device, the second device can have enough energy to support communication transmission, thereby ensuring the successful execution of communication transmission of the second device.

For example, step 5101 may be implemented as an independent embodiment, and step 5102 may be implemented as an independent embodiment, but the present invention is not limited thereto.

[0490] The following is an exemplary introduction to the above method.

[0491] Optional embodiment 1

[0492] In a network, A-IoT network devices communicate with A-IoT terminal devices. A-IoT network devices include base stations, terminals, intermediate nodes, auxiliary nodes, etc. A-IoT terminal devices are of at least one of Type 1, Type 2a, Type 2b, and Type 2c. The A-IoT terminal devices collect energy from the environment to power the A-IoT terminal devices for communication transmission. The energy in the environment includes both natural and artificial energy.

[0493] Before the A-IoT network device initiates communication transmission scheduling to at least one A-IoT terminal device, it is necessary to reserve a first duration for the at least one A-IoT terminal device. The first duration is the time required for the A-IoT terminal device to collect enough energy from the environment to complete a communication transmission. The communication transmission includes at least one of the following (including a combination of at least two of the following): uplink data transmission, backscattering, uplink data processing, uplink control information processing, switching between charging circuit and communication circuit, uplink control signaling transmission, downlink data reception, downlink data processing, downlink control information processing, downlink control signaling reception, waiting for retransmission, and synchronization information reception.

[0494] The first duration is determined by at least one of the following methods:

[0495] Optional Example 1:

[0496] The protocol predefines a first duration, which is the time required for an A-IoT terminal device to collect sufficient energy from the environment to complete a communication transmission.
