FIG. 3 shows a schematic flowchart of a method for providing energy in an embodiment of the present application, and the method 300 may be executed by a first device. In other words, the method may be performed by software or hardware installed on the first device. As shown in Figure 3, the method may include the following steps.

S310: The first device sends a signal to the second device according to the configuration parameters of the first target transmission mode, so as to provide energy to the second device through the signal, where the first target transmission mode includes: a first target period , the first target period includes an active period and/or an inactive period.

Wherein, during the active period, the first device sends a signal to the second device, and during the inactive period, the first device does not send a signal to the second device.

In this embodiment of the present application, the first device may be configured with one or more transmission modes, one or more periods may be configured in the configuration parameters of the transmission mode, and a period may only have an active period, or only an inactive period, or The active period and the inactive period may be included, and the first device may select the first target period in the process of sending the signal.

When a cycle includes an active period and an inactive period, the active period and the inactive period may be continuous or discrete. For example, in a cycle, the specified duration after the beginning of the cycle can be set as the active period, and the subsequent duration can be set as the inactive period, or a cycle can be divided into multiple time units, and each time unit can be set to be Whether it belongs to the active period or the inactive period, the time units belonging to the active period or the inactive period can be discontinuous.

With the technical solutions provided in the embodiments of the present application, the first device (ie, the energy providing device or the energy supplying device) sends the second device (ie the energy receiving device, such as the above backscattering device) to the second device (ie the energy receiving device) according to the configuration parameters of the first target transmission mode. ) sends a signal to provide energy to a second device via the signal, wherein the first target transmission mode includes a first target period including an active period and/or an inactive period, the first target transmission mode The signal is sent to the second device during the active period, but is not sent to the second device during the inactive period, so that the power consumption of the first device can be reduced and the time period during which the first device provides energy to the second device can be extended.

In a possible implementation manner, the configuration parameters of the first target transmission mode may include at least one of the following:

(1) A first cycle and a first duration corresponding to the first cycle, wherein the first device sends a signal to the second device during the first duration of the first cycle.

That is, the configuration parameters of the first target transmission mode include indication information indicating the length of the first period and the duration within the first period. The first duration means that the first device sends a signal to the second device within the first duration. The first duration may be part or all of the active period in the first cycle.

Optionally, the first duration is at least greater than the energy storage time required by the second device. The energy storage time may be notified to the first device by the second device, or may be notified to the first device by a third device (for example, a network-side device), which is not specifically limited in this embodiment of the present application.

(2) A second period and a second duration corresponding to the second period, wherein the first device sends a signal to the second device during the second duration of the second period.

That is, the configuration parameters of the first target transmission mode include indication information indicating the length of the second period and the duration in the second period. Wherein, the first device sends a signal to the second device for a second duration.

In this embodiment of the present application, the length of the second period is smaller than the length of the first period. For example, the length of the first period may be m times the length of the second period, where m is an integer greater than one.

(3) A first timer, wherein the first timer is started when the data sent by the second device is monitored, and the first device sends a message to the second device before the first timer times out. The device sends a signal.

That is, the configuration parameter of the first target transmission mode includes indication information indicating the duration of the first timer. The first timer is used to monitor the data sent by the second device, and is started when the data sent by the second device is monitored. During the timing of the first timer, the first device sends a signal to the second device, which is equivalent to to extend the duration (or active period) of the current cycle.

(4) A second timer, wherein the duration of the second timer is K of the second periods, where K is an integer greater than 0.

That is, the configuration parameter of the first target transmission mode includes indication information indicating the duration of the second timer. Wherein, the second timer is used to calculate K second cycles, and if the first target cycle is the second cycle, the second timer starts at the start of the second cycle. Before the second timer expires, if the first timer has not been started, the first target period may be switched to the first period. That is, if the first timer has not been started from the start of the second timer to the expiration of the second timer, it means that the second device may be currently in an inactive state, and the first device can lengthen the monitoring period to further save energy. .

In the above possible implementation manner, the first target period may be the first period or the second period, and the inactive period of the first target period is a period other than the active period in the period .

Optionally, in the above possible implementation manner, the configuration parameter of the first target transmission mode may further include: a first signal parameter. The first signal parameter is used to indicate at least one of energy, transmit power, and beam direction of a signal sent by the first device. That is, the configuration parameters of the first target transmission may also include parameters related to energy or power, such as transmit power, transmit beam direction, or other parameters associated with transmit beam direction.

Wherein, the first signal parameter may be one of the configuration parameters belonging to the first target transmission mode and configured together with other parameters; or may be configured independently from other parameters of the first target transmission mode and configured independently. For example, the first device may be wirelessly connected to the base station, and the base station may configure other parameters of the first target transmission mode and the first signal parameter through air interface control, respectively.

In the above possible implementation manner, after the first device sends a signal to the second device during the active period of the first target period, if the second device receives the signal within the first duration or the second duration The signal sent or the energy of the signal sent by the second device is detected, and the first timer is started; the first timer is started and has not timed out, and the first device sends to the device according to the first preset mode. The second device sends a signal; if the signal sent by the second device is received before the first timer times out, the first timer is restarted; if the first timer times out, according to the first timer Two preset modes send a signal to the second device. Through this possible implementation, when the signal sent by the second device is received or the energy of the signal sent by the second device is detected, the time period for sending the signal to the second device is increased, so that the second device has energy When required, the duration of supplying energy to the second device is increased to meet the demand of the second device.

In the above implementation manner, if the signal sent by the second device is not received or the energy of the signal sent by the second device is not detected within the first duration or the second duration, the first duration or the second duration After the time, the first device enters the inactive period of the first target period, and after the first target period ends, the first device enters the first duration or the second duration of the first target period again.

For example, the first device may first take the first target cycle as the second cycle, start a second timer when entering the second cycle, and send a signal to the second device within the second duration of the second cycle, If, within the second duration, the first device receives a signal sent by the second device, eg, detects a signal whose energy exceeds a threshold, or demodulates a signal sent by the second device, the first device starts the first timer , before the first timer expires, send a signal to the second device according to the first preset mode (equivalent to the extension of the active period of the current first target period), if the second device is received before the first timer expires If the signal is sent by the device, the second timer is restarted, that is, the active period of the first target period is extended again. If the first timer times out, the first device sends a signal to the second device according to the second preset mode. If the first device does not receive the signal sent by the second device within the second duration, the first device performs the inactive period of the second cycle until the end of the second cycle, and the second device enters the next second cycle, The signal is sent to the second device for a second duration of the second period, and so on.

Optionally, sending a signal to the second device according to the first preset mode may include: sending a signal to the second device with a first duration as a period, wherein the first duration is less than the first target period. That is, the signal is sent to the second device with a period smaller than the first target period to meet the energy demand of the second device.

Alternatively, sending the signal to the second device according to the first preset mode may also include: continuously sending the signal to the second device. That is, the signal is continuously sent to the second device within the timing range of the first timer to meet the energy demand of the second device.

Optionally, sending a signal to the second device according to the second preset mode may include: after the first timer expires, the first device sends a signal according to the second cycle and starts the second device. A timer, if the first timer is not started before the second timer times out, the first device sends a signal according to the first period. That is, when the first timer times out, the second device switches the first target cycle to the second cycle, and if no signal sent by the second device is received for K consecutive second cycles, the first device switches the first target cycle For the first cycle, a signal is sent to the second device in the first cycle, so as to save the power consumption of the first device.

Alternatively, sending the signal to the second device according to the second preset mode may include: not sending the signal to the second device, that is, the first device is in an inactive period.

In a possible implementation, multiple transmission modes may be configured, each transmission mode is configured with a set of the above configuration parameters, and the second device or the third device may indicate which transmission mode to use by the first device through signaling. Therefore, in this possible implementation manner, before S310, the method may further include: receiving a first signaling sent by the second device or a third device, where the first signaling indicates the first signaling The device uses the first target transmission mode. The third device may be a network side device, for example, a base station, which is not specifically limited in this embodiment of the present application.

In a possible implementation manner, the configuration parameters of the first target transmission mode are pre-configured and/or indicated by the third device. For example, the configuration parameters of the first target transmission mode may be pre-configured for the first device. Alternatively, the configuration parameters of the first target transmission mode may also be indicated for the third device. Alternatively, the configuration parameters of the first target transmission mode may be partially pre-configured and partially indicated by the third device. For example, the first period of the first target transmission mode and the first duration corresponding to the first period, the second period and the second duration corresponding to the second period, the first timer, and the second timer may be preconfigured , and the first signal parameter may be indicated by the third device.

In another possible implementation manner of the embodiment of the present application, another set of configuration parameters may also be used for the configuration parameters of the first target transmission mode. In this possible implementation manner, the configuration parameters of the first target transmission mode include: the number M of time units included in the first target period, where M is an integer greater than 1; The time unit of the active period. That is, in this possible implementation manner, a first target period includes M time units, and the configuration parameters of the first target transmission mode include the number of time units included in the first target period, and M times Indication information of the time units belonging to the active period in the unit, where the indication information may directly indicate which time units are active periods, or may indicate which time units are inactive periods, which are not specifically limited in this embodiment of the present application.

In the above possible implementation manner, the time unit may be predefined, for example, may be one or more symbols, or one or more time slots, etc., which are not limited in the specific embodiments of the present application.

In the above possible implementation manner, the configuration parameter of the first target transmission mode may further include: a second signal parameter, where the second signal parameter is used to indicate the energy, transmit power and beam of the signal sent by the first device at least one of the directions.

That is, the configuration parameters of the first target transmission mode may further include parameters related to energy or power, for example, the transmit power of the transmitted signal, the transmit beam direction, and the like. Wherein, the second signal parameter may be configured uniformly with other configuration parameters of the first target transmission mode; or, may also be independent of other configuration parameters of the first target transmission mode, for example, the first device may be wirelessly connected to the base station, The base station may separately configure other configuration parameters and second signal parameters of the first target transmission mode through the air interface.

In the above possible implementation manner, optionally, multiple transmission modes using the above configuration parameters may also be configured, and the first target transmission mode may be indicated to the first device by dedicated signaling. Therefore, in this possible implementation manner, before the first device sends a signal to the second device according to the configuration parameters of the first target transmission mode, the method may further include: receiving the signal sent by the second device or the third device the second signaling, wherein the second signaling instructs the first device to use the first target transmission mode. The third device may be a device such as a base station. In this possible implementation manner, the second device or the third device may indicate the first target transmission mode to the first device through second signaling.

The second signaling may indicate various configuration parameters of the first target transmission mode, for example, the second signaling may directly indicate the number M of time units included in the first target period in the first target transmission mode, and The time units belonging to the active period among the M said time units. Alternatively, multiple sets of transmission modes and values of configuration parameters corresponding to each transmission mode may also be configured or agreed in advance, and the second signaling may indicate the identifier of the first target transmission mode.

Optionally, a transmission mode can also be activated through a target signal or target signaling. Therefore, before the first device sends a signal to the second device according to the configuration parameters of the first target transmission mode, the method may further include: in the case of receiving the target signal or target signaling sent by the second device , activate or switch to the first target transmission mode.

For example, the first device receives a certain target signal or certain target signaling from the second device, thereby activating or switching to the first target transmission mode, for example, receiving a signal from the second device on the same carrier frequency as the first device , for another example, through energy detection (reaching a preset threshold value), it is determined that the tag is signaling. The first target transmission mode may be configured in advance, or the mode of the first target transmission mode is determined according to the detected signal characteristics or modes.

Optionally, the activation time of the first target transmission mode may be the X th symbol or time slot after the first device receives the target signal or target signaling, where X is a protocol agreement or a network configuration.

Optionally, the transmission mode may also be switched according to the third timer. Therefore, before the first device sends a signal to the second device according to the configuration parameters of the first target transmission mode, the method may further include: when entering the second target transmission mode, starting a third timer, and in the first target transmission mode Before the three timers expire, the signal sent by the second device is not received, and it switches to the first target transmission mode; wherein the configuration parameters of the first target transmission mode and the second target transmission mode are different from each other. Exactly the same.

In the above implementation manner, if the signal sent by the second device is received before the third timer expires, the third timer is restarted, that is, the first device continues to maintain the second target transmission mode.

In the above implementation manner, because the first device does not receive a signal sent by the second device before switching to the first target transmission mode during the timing period of the third timer, the first target transmission mode in the first target transmission mode The cycle length may be greater than the second target cycle length in the second target transmission mode, so as to increase the cycle of sending signals to the second device and further reduce the power consumption of the first device. Of course, it is not limited to this, the first target period of the first target transmission mode may also be the same as the second target period of the second target transmission mode, but the time unit included in the active period in the first target period is longer than that of the second target period. The active period in the cycle contains few time units.

In the above implementation manner, the length of the third timer may be determined according to an actual application, may be agreed in a protocol, or may be configured by a network side device, which is not specifically limited in this embodiment of the present application.

In a possible implementation manner, the first device may also send a signal to the second device in the first target transmission mode based on a power supply request sent by the second device. Therefore, in this possible implementation manner, before the first device sends a signal to the second device according to the configuration parameter of the first target transmission mode, the method further includes: receiving a power supply request sent by the second device. After receiving the power supply request from the second device, the first device may send a signal to the second device in the first target transmission mode.

That is, the second device may request the first device to send a signal to the second device to obtain energy. For example, when the second device needs to send data, the second device may send first indication information instructing the first device to send a signal. Alternatively, the second device may also request the first device not to send a signal to the second device. For example, when the second device does not need to send data, the second device may send first indication information indicating that the first device does not send a signal.
