DETAILED DESCRIPTION

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

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

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;

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.

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.

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.

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.

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

Uplink data sending;

Charging circuit and communication circuit switching;

Uplink control signaling is sent;

Downlink data reception;

Downlink data processing;

Downlink control signaling processing;

Downlink control signaling reception;

Waiting for retransmission;

Synchronous information reception.

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.

In conjunction with some embodiments of the first aspect, in some embodiments, the second device includes different types;

The determining of the first duration corresponding to the at least one second device includes at least one of the following:

Determine a first duration based on the protocol; the first duration is applicable to different types of the second device;

Multiple first durations are determined based on protocol agreement; different first durations are applicable to different types of the second devices.

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

A first duration corresponding to the second device is determined from the second device, wherein the first duration determined from the second device is included in at least one first duration agreed upon in the protocol.

In combination with some embodiments of the first aspect, in some embodiments, the first duration corresponding to the second device is set on the second device when the second device leaves the factory.

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

When the second device registers the network, reading the first duration corresponding to the second device from the second device;

When the second device accesses the network for the first time, receiving a first duration corresponding to the second device reported by the second device;

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.

The communication transmission schedule is initiated to at least one second device.

In the above embodiment, after the first device performs the first operation for the first duration, causing the second device to charge for the first duration, the first device initiates a communication transmission schedule to at least one second device. Since the second device first collects sufficient energy to support the communication transmission and then receives the communication transmission schedule initiated by the first device, the second device has sufficient energy to support the communication transmission, thereby ensuring the successful execution of the communication transmission by the second device.

In conjunction with some embodiments of the first aspect, in some embodiments, the method further includes:

The first duration is configured for at least one second device.

In the above embodiment, the first device will also configure the first duration for the second device, so that the second device can know the charging time it needs. When the second device collects energy, it can collect energy based on the first duration, thereby avoiding the problems of "the charging time of the second device is too long, resulting in unnecessary charging operations and waste of resources; or the charging time of the second device is too short, resulting in insufficient charging, and causing communication transmission failure". This ensures the successful execution of communication transmission while avoiding resource waste.

In combination with some embodiments of the first aspect, in some embodiments, the measurement unit of the first duration includes an absolute time unit and/or a relative time unit.

In the above embodiment, the measurement unit of the first duration is defined, so the first device and the second device can uniformly determine the specific length of the first duration based on the measurement unit, avoiding the situation of "a series of errors caused by inconsistent understanding of the measurement unit of the first duration by the first device and the second device", thereby ensuring communication accuracy and precision.

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.

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, 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, 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. However, there is currently no clear solution to the problems of "how to determine the charging time, and how to configure and/or notify the charging time so that the A-IoT devices can charge based on the charging time."

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

It should be noted that the above The above is only an example introduction to communication transmission, wherein a complete communication transmission may also include other processes and is not limited to the above examples.

The following is a detailed introduction to “how the second device specifically determines the first duration corresponding to the second device”.

Optionally, the method for the second device to determine the first duration corresponding to the second device may include at least one of the following methods:

In the first type, the second device determines the first duration corresponding to the second device based on a protocol agreement.

In some embodiments, the second 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.

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.

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.

In the second type, the second device independently determines the first duration corresponding to the second device.

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.

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.

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.

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:

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

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;

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.

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.

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.

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.

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.

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 transmit power of the second signal, and a receive 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, the second signal may be an Energy Source (ES) signal.

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.

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

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.”

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.

Optional embodiment 4

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.

Before executing the communication transmission scheduling initiated by the A-IoT network device, the A-IoT terminal device needs to perform charging for at least the first duration. The first duration is the time required for the A-IoT terminal device to collect enough energy from the environment to complete N communication transmissions. The communication transmission includes at least one of the following (including a combination of at least two of the following): uplink data sending, backscattering, uplink data processing, uplink control information processing, switching between charging circuit and communication circuit, uplink control signaling sending, downlink data reception, downlink data processing, downlink control information processing, downlink control signaling reception, waiting for retransmission, and synchronization information reception. The N is predefined by the protocol.

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

Optional Example 1:

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. The first duration is measured in absolute time units such as hours, minutes, seconds, milliseconds, microseconds, nanoseconds, etc., for example, 500ms; or the first duration is measured in relative time units such as radio frames, radio subframes, time slots, time domain symbols, etc., for example, 100 time slots. Furthermore, the protocol can predefine a single first duration value or multiple first duration values.

In one implementation, the protocol defines a first duration value for device 1, 2a, 2b, and 2c, which are denoted as T_1, T_2a, T_2b, T_2c, and T_2d, respectively.

Optional Example 2:

The protocol predefines a first duration, which is the time required for the A-IoT terminal device to collect enough energy from the environment to complete a communication transmission. The protocol predefines at least one first duration value, and the device reports its actual corresponding first duration value. The first duration is measured in absolute time units such as hours, minutes, seconds, milliseconds, microseconds, nanoseconds, etc., for example, 500ms; or the first duration is measured in relative time units such as radio frames, radio subframes, time slots, time domain symbols, etc., for example, 100 time slots.

Furthermore, the device reports at least one of the following processes:

When leaving the factory, the device is burned with the first duration value information;

When registering the network, the device reads the first duration value information;

When accessing the network for the first time, the device reports the first duration value.

When the A-IoT network device queries the first duration information, the device feedback reports the first duration value information.

In one implementation, the protocol predefines four first durations: 500ms, 1000ms, 15000ms, and 5000ms, represented by the numbers 00, 01, 10, and 11. When device A is programmed with 00, meaning 500ms, it means that device A needs 500ms to complete charging for N communication transmissions.

Optional Example 3:

The protocol predefines a first duration, which is the time required for the A-IoT terminal device to collect enough energy from the environment to complete a communication transmission. The protocol predefines the first duration value of the device under different conditions, and the conditions include but are not limited to at least one of the following: channel environment, distance between the A-IoT network device and the A-IoT terminal device, impulse signal transmission power, and charging signal reception power. The first duration is measured by absolute time units, such as hours, minutes, seconds, milliseconds, microseconds, nanoseconds, etc., for example, 500ms; or, the first duration is measured by relative time units, such as radio frames, radio subframes, time slots, time domain symbols, etc., for example, 100 time slots.

Furthermore, the A-IoT network device determines the condition of the device by receiving a first reference signal sent by the device, thereby obtaining a corresponding first duration value. The first reference signal is predefined by the protocol and is used to determine the condition of the device.

Among the above three methods, the first duration value is determined by at least one of protocol pre-definition, configuration of the A-IoT network device to the A-IoT terminal device, reporting by the A-IoT terminal device to the A-IoT network device, and advance notification of the manufacturer to the A-IoT network device.
