The energy supply method provided by the embodiment of the present application is described in detail below with reference to the accompanying drawings by specific embodiments and application scenarios thereof.

Fig. 3 shows a schematic flow diagram of an energy providing method in an embodiment of the application, which method 300 may be performed by a first device. In other words, the method may be performed by software or hardware installed on the first device. As shown in fig. 3, the method may include the following steps.

S310, a first device sends a signal to a second device according to a configuration parameter of a 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 comprising an active period and/or an inactive period.

Wherein the first device transmits a signal to the second device during the active period and the first device does not transmit a signal to the second device during the inactive period.

In this embodiment, the first device may be configured with one or more transmission modes, one or more cycles may be configured in configuration parameters of the transmission modes, only an active period may be provided in a cycle, only an inactive period may be provided, or both an active period and an inactive period may be provided, and the first device may select the first target cycle in a process of sending a signal.

In the case where the active period and the inactive period are included in one cycle, the active period and the inactive period may be continuous or discrete. For example, in one period, a specified duration after the start of the period may be set as an active period, and the subsequent duration is an inactive period, or one period may be divided into a plurality of time units, each time unit is set as an active period or an inactive period, and the time units belonging to the active period or the inactive period may be discontinuous.

According to the technical solution provided by the embodiment of the present application, a first device (i.e., an energy providing device or an energy providing device) sends a signal to a second device (i.e., an energy receiving device, such as the above-mentioned backscatter device) according to a configuration parameter of a 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, and the first device sends the signal to the second device in the active period and does not send the signal to the second device in the inactive period, so that power consumption of the first device can be reduced, and a duration for which the first device provides energy to the second device can be prolonged.

In one possible implementation, the configuration parameter of the first target transmission mode may include at least one of:

(1) the first device sends a signal to the second device during the first duration of the first period.

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 refers to the time period during which the first device transmits a signal to the second device. The first duration may be a portion or all of an active period in the first cycle.

Optionally, the first duration is at least greater than an 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 limited in the 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 within the second period. Wherein the first device transmits a signal to the second device for a second duration.

In the 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 1.

(3) The first timer is started when monitoring data sent by the second equipment, and the first equipment sends a signal to the second equipment before the first timer is overtime.

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 configured to listen to data sent by the second device, and is started when the data sent by the second device is listened to, and during the timing period of the first timer, the first device sends a signal to the second device, that is, the duration (or active period) of the current period is extended.

(4) And a second timer, wherein the duration of the second timer is K second periods, and 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. The second timer is used for calculating K second periods, and when the first target period is the second period, the second timer is started at the beginning of the second period, and if the first timer is not started before the second timer is started and the second timer is overtime, the first target period can be switched to the first period. That is, if the first timer is not started yet from the start of the second timer to before the timeout of the second timer, it indicates that the second device may be currently in an inactive state, and the first device may increase the monitoring period to further save power.

In the 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 foregoing possible implementation manner, the configuration parameters of the first target transmission mode may further include: a first signal parameter. Wherein the first signal parameter is used to indicate at least one of energy, transmit power, and beam direction of a signal transmitted 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 (beam) direction, or other parameters associated with the transmit beam direction, etc.

Wherein the first signal parameter may be configured with other parameters along with one of the configuration parameters belonging to the first target transmission mode; or may be configured separately from other parameters of the first target transmission mode. 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 respectively through air interface control.

In the possible implementation manner, after the first device sends a signal to the second device in the active period of the first target period, if the signal sent by the second device is received within the first duration or the second duration or the energy of the signal sent by the second device is detected, the first timer is started; the first timer is started and is not overtime, and the first equipment sends a signal to the second equipment according to a first preset mode; if the signal sent by the second equipment is received before the first timer is overtime, restarting the first timer; and if the first timer is overtime, sending a signal to the second equipment according to a second preset mode. Through the possible implementation manner, 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 when the second device has an energy demand, the time period for providing the energy to the second device is increased to meet the demand of the second device.

In the foregoing 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, after the first duration or the second duration, the first device enters an 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 use the first target period as the second period, start the second timer when entering the second period, and send a signal to the second device within the second duration of the second period, if the first device receives the signal sent by the second device within the second duration, for example, a signal whose energy exceeds the threshold is detected or a signal sent by the second device is demodulated, the first device starts the first timer, and sends a signal to the second device according to the first preset mode (which is equivalent to that the active period of the current first target period is extended) before the first timer expires, and if the first device receives the signal sent by the second device before the first timer expires, restart the second timer, that is, extend the active period of the first target period again. And if the first timer is overtime, the first equipment sends a signal to the second equipment according to a 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 an inactive period of a second period until the second period ends, the second device enters a next second period, sends the signal to the second device within the second duration of the second period, and so on.

Optionally, the sending the signal to the second device according to the first preset mode may include: and sending a signal to the second equipment by taking a first time length as a period, wherein the first time length is less than the first target period. I.e. to signal 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 transmitting a signal to the second device. I.e. continuously sending a signal to the second device within the timing range of the first timer to meet the energy requirement of the second device.

Optionally, the sending the signal to the second device according to the second preset mode may include: and after the first timer is overtime, the first equipment sends a signal according to the second period and starts the second timer, and if the first timer is not started before the second timer is overtime, the first equipment sends the signal according to the first period. When the first timer times out, the second device switches the first target period to the second period, and if the signals sent by the second device are not received in the K continuous second periods, the first device switches the first target period to the first period and sends the signals to the second device in the first period, so that the power consumption of the first device is saved.

Alternatively, the sending the signal to the second device according to the second preset mode may include: no signal is sent to the second device, i.e. the first device is in an inactive period.

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

In one possible implementation, the configuration parameter of the first target transmission mode is a pre-configuration and/or a third device indication. For example, the configuration parameters of the first target transmission mode may be configured for the first device in advance. Alternatively, the configuration parameter of the first target transmission mode may also be indicated for the third device. Still alternatively, the configuration parameters of the first target transmission mode may be partly pre-configured and partly indicated by the third device. For example, the first period of the first target transmission mode and a first duration corresponding to the first period, the second period and a 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, the configuration parameter of the first target transmission mode may also adopt another set of configuration parameters. 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 is an integer greater than 1; the time units belonging to the active period of the M time units. That is to say, in this possible implementation manner, one first target period includes M time units, and the configuration parameter of the first target transmission mode includes the number of time units included in the first target period and indication information of a time unit belonging to an active period in the M time units, where the indication information may directly indicate which time units are active periods or indicate which time units are inactive periods, and this is not limited in this embodiment of the present application.

In the foregoing possible implementation manners, the time unit may be predefined, and may be, for example, one or more symbols, or one or more time slots, and the like, which is not limited in the embodiment of the present application.

In the foregoing possible implementation manner, the configuration parameters of the first target transmission mode may further include: a second signal parameter, wherein the second signal parameter is used to indicate at least one of an energy, a transmit power, and a beam direction of a signal transmitted by the first device.

That is, the configuration parameters of the first target transmission mode may further include parameters related to energy or power, such as the transmission power of the transmitted signal, the transmission beam direction, and the like. The second signal parameter can be configured with other configuration parameters of the first target transmission mode in a unified way; or may be independent of other configuration parameters of the first target transmission mode, for example, the first device may be connected to the base station in a wireless manner, and the base station may configure the other configuration parameters of the first target transmission mode and the second signal parameter through an air interface, respectively.

In the foregoing possible implementation manner, optionally, a plurality of transmission modes using the configuration parameter may also be configured, and the first target transmission mode may be indicated by a dedicated signaling. 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 may further include: and receiving second signaling sent by the second device or a third device, wherein the second signaling indicates that the first device uses the first target transmission mode. The third device may be a base station or the like. In this possible implementation, the second device or the third device may indicate the first target transmission mode to the first device through the 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 a time unit belonging to an active period in the M time units. Or, multiple sets of transmission modes and values of configuration parameters corresponding to the transmission modes may be configured or agreed in advance, and the second signaling may indicate the identifier of the first target transmission mode.

Alternatively, a transmission mode can also be activated by 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: and activating or switching to the first target transmission mode under the condition of receiving a target signal or a target signaling sent by the second equipment.

For example, the first device receives a target signal or a target signaling from the second device, and activates or switches to the first target transmission mode, for example, receives a signal from the second device on the same carrier frequency as the first device, and determines that tag is signaling, for example, by energy detection (reaching a predetermined threshold). Wherein 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 mode.

Optionally, the time of activation of the first target transmission mode may be an xth symbol or slot after the first device receives the target signal or the target signaling, where X is agreed by a protocol or configured by a network.

Alternatively, the transmission mode may 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 a second target transmission mode, starting a third timer, and before the third timer is overtime, not receiving a signal sent by the second equipment, and switching to the first target transmission mode; wherein the configuration parameters of the first target transmission mode and the second target transmission mode are not identical.

In the foregoing implementation manner, if the signal sent by the second device is received before the third timer times out, the third timer is restarted, that is, the first device continues to remain in the second target transmission mode.

In the foregoing implementation manner, since the first device switches to the first target transmission mode without receiving the signal sent by the second device during the timing period of the third timer, the first target period length in the first target transmission mode may be greater than the second target period length in the second target transmission mode, so as to increase the period for sending the signal to the second device, and further reduce the power consumption of the first device. Of course, the present invention is not limited thereto, and the first target period of the first target transmission mode may be the same as the second target period of the second target transmission mode, but the active period of the first target period may include fewer time units than the active period of the second target period.

In the foregoing implementation manner, the length of the third timer may be determined according to practical applications, may be agreed by a protocol, or may be configured by a network side device, and is not limited in this embodiment of the application.

In one possible implementation, the first device may also send a signal to the second device in the first target transmission mode based on the power 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: and receiving an energy supply request sent by the second equipment. The first device may send a signal to the second device in the first target transmission mode upon receiving a power request from the second device.

Optionally, in the possible implementation manner, some information of the request of the second device may also be carried in the energy supply request. Optionally, the energy supply request may include, but is not limited to, information of one of the following:

(1) first indication information, wherein the first indication information indicates that the first device transmits a signal, or the first indication information indicates that the first device does not transmit a signal; that is, the second device may request to send an indication to the first device indicating that the first device is sending or not sending a signal by powering up. That is, the second device may request the first device to send a signal to the second device to obtain energy, for example, the second device may send first indication information indicating that the first device sends a signal when it needs to send data. Alternatively, the second device may request the first device not to transmit a signal to the second device, for example, the second device may transmit first indication information indicating that the first device does not transmit a signal when it is not necessary to transmit data.

(2) Second indication information, wherein the second indication information indicates that the first device transmits a signal and a power and/or a beam direction of the transmitted signal, or the second indication information indicates that the first device does not transmit a signal; that is, the second indication information may indicate that the first device transmits a signal and indicate the power and/or beam direction used by the first device to transmit the signal, for example, the second device may transmit the second indication information indicating that the first device transmits the signal and the power and/or beam direction of the transmission signal when data needs to be transmitted. Alternatively, the second indication information indicates that the first device does not transmit a signal, e.g., the second device may transmit the second indication information indicating that the first device does not transmit a signal when it is not required to transmit data.

(3) Third indication information, wherein the third indication information indicates that the first device transmits a signal, and time domain resource information of the transmitted signal and power and/or beam direction of the transmitted signal; or, the third indication information indicates that the first device does not transmit a signal and a time when the first device does not transmit a signal; that is, the third indication information may indicate that the first device transmits a signal, time domain resources in which the signal is transmitted, and power and/or beam direction of the transmitted signal, or indicate in which time periods the first device does not transmit the signal.

(4) Fourth indication information, wherein the fourth indication information indicates configuration parameters of the first transmission mode. I.e. the second device carries the configuration parameters of the desired first transmission mode in the energizing request.

Optionally, in order to make the first device and the second device understand the same, the energy supply request may further include: the first device transmits characteristic parameters of signals, wherein the characteristic parameters comprise at least one of the following parameters: signal waveform, Modulation Coding Scheme (MCS), modulation scheme, frequency resource information, code domain resource information, and sequence information. Through the implementation, the first device can know the characteristic parameters expected by the second device. Wherein the second device may include the characteristic parameter in the power request when requesting the first device to transmit the signal.

In practical applications, a plurality of energy supply devices may exist around the second device, and in order to enable the energy supply device receiving the common energy supply request to determine the receiving party of the energy supply request, the energy supply request may also carry identification information of the first device, for example, information such as the number of the first device.

Optionally, in order to make the first device know the requirement of the second device, the energy supply request may further include at least one of the following:

(1) energy storage time required by the second device.

(2) The stored energy of the second device receives power.

(3) A communication receive power of the second device.

In the above possible implementation manner, after receiving the power supply request sent by the second device, the first device may send the power supply request to the second device according to information carried in the power supply request. Optionally, after receiving the power supply request sent by the second device, the method may further include:

if the first device can meet a first transmission mode requested by the energy supply request, taking the first transmission mode as the first target transmission mode;

and if the first equipment cannot meet the first transmission mode requested by the energy supply request, sending non-confirmation information to the second equipment.

That is, in this alternative implementation, after receiving the power supply request, the first device sends a signal to the second device with the first transmission mode as the first target transmission mode if the requested first transmission mode can be satisfied, and sends non-acknowledgement information (NACK) to the second device if the first transmission mode cannot be satisfied.

In the case that the first device cannot satisfy the first transmission mode requested by the first device, optionally, the second device may send, to the second device, indication information of a second transmission mode; if receiving a confirmation message returned by the second device, taking the second transmission mode as the first target transmission mode; if an energy supply request for requesting a third transmission mode returned by the second equipment is received, if the first equipment can meet the third transmission mode, taking the third transmission mode as the first target transmission mode; the values of the configuration parameters of the first transmission mode, the second transmission mode, and the third transmission mode are not completely the same, for example, the values of some configuration parameters in the first transmission mode, the second transmission mode, and the third transmission mode are not the same, or the values of all configuration parameters in the first transmission mode, the second transmission mode, and the third transmission mode are not the same.

In this embodiment of the present application, the transmission power of the signal sent by the first device to the second device may be fixed, may also be requested by the second device, may also be negotiated between the first device and the second device, and may also be adjusted by the first device itself.

In one possible implementation, the first device sends a signal to the second device according to the configuration parameter of the first target transmission mode, where the signal includes one of:

(1) the first device sends a signal to the second device at a fixed transmit power.

After receiving the signal of the first device, the second device may determine, according to the strength of the received signal, the energy storage time required by itself, and send an energy supply request to the first device, where the energy supply request may include a time domain resource length, and request the first device to send a signal within the time domain resource length, so as to meet the energy storage requirement of the first device.

(2) The method comprises the steps that the first equipment sends signals to the second equipment by fixed transmitting power, after an energy supply request sent by the second equipment is received, the fixed transmitting power is adjusted according to a first power adjustment step length carried in the energy supply request, and the signals are sent to the second equipment by the adjusted transmitting power.

After receiving the signal of the first device, the T second device may determine, according to the strength of the received signal, the energy storage received power required by itself, and send an energy supply request to the first device, where the energy supply request may include a time domain resource length and a power adjustment step size (for example, increasing X dB or decreasing Y dB) of the signal sent by the first device, and request the first device to send a signal after performing device processing on the current transmission power by the power adjustment step size within the time domain resource length, so as to meet the energy storage requirement of the first device.

(3) And the first equipment sends a signal to the second equipment by using the first transmission power requested by the second equipment, and after receiving a second power adjustment step length sent by the second equipment, the first transmission power is adjusted according to the second power adjustment step length so as to adjust the obtained second transmission power and send the signal to the second equipment.

For example, the second device sends an energy supply request (for example, 1bit) to the first device, and the first device sends a signal according to the first power after receiving the energy supply request of the second device; after receiving the signal, the second device sends the time domain resource length and the power adjustment step length of the signal sent by the first device to the first device, and after adjusting the current transmission power according to the power adjustment step, the first device sends the signal in the time domain resource length according to the adjusted transmission power.

(4) The method comprises the steps that the first equipment receives the signal quality of an energy supply request and the third transmitting power of the energy supply request, the path loss between the first equipment and the second equipment is determined, the fourth transmitting power is determined according to the path loss and the energy power expected to be received by the second equipment, and the fourth transmitting power is used for sending a signal to the second equipment, wherein the energy supply request is sent by the second equipment, and the energy supply request carries the third transmitting power and the energy power expected to be received.

For example, the second device sends an energy supply request to the first device, wherein the energy supply request comprises the expected received energy power and the transmitting power of the energy supply request signal; the first device determines the path loss between the second device and the first device according to the received RSRP of the energy supply request and the signal transmission power of the energy supply request; the first equipment determines own transmitting power according to the path loss and the energy power expected to be received by the second equipment; the first device transmits a signal in accordance with the transmit power. By this possible implementation, when the first device transmits a signal, the first device may determine its transmit power by taking into account the path loss between the first device and the second device, so that the power at which the second device receives the signal can satisfy the energy power it expects to receive.

In another possible implementation, the second device may not participate in the adjustment of the transmission power, and the first device determines the transmission power by polling for different transmission powers. In this possible implementation manner, the first device sends a signal to the second device according to the configuration parameter of the first target transmission mode, including the following steps:

step 1, the first device sends a signal with a first transmission power. For example, a first device transmits signals at a first transmit power and a first beam direction.

And step 2, if the signal sent by the second device is not received in the first time window, after the first time window is finished, the first transmitting power is increased by a first step length to obtain a second transmitting power, and the signal is sent by the second transmitting power. Wherein the first step size and the time window may be preset.

And if the signal transmitted by the second equipment is received in the first time window, continuing to transmit the signal at the first transmission power.

And 3, if the signal sent by the second device is not received in the second time window, after the second time window is finished, the second transmission power is increased by a first step length to obtain a third transmission power, and the signal is sent by the third transmission power until the signal sent by the second device is received in the nth time window or the number of times of power increase reaches a threshold value, wherein n is an integer greater than or equal to 1.

For example, a first device transmits a signal at a first transmit power and in a first beam direction (optional); if the first device does not receive the signal of the second device within the first time window (energy detection based on a threshold or information demodulation is obtained), the first device raises the first transmission power by a first step length (the first transmission power is raised by the first step length to obtain a second transmission power) after the first time window is finished, and the first device sends the signal in the second transmission power and the first beam direction (optional); if the first device receives the second device's signal (which may be threshold-based energy detection, or demodulated to information) within a first time window, the first device continues to transmit signals at the first transmit power and in the first beam direction (optional). If the first device does not receive the signal of the second device in the second time window, the first device raises the second transmitting power by the first step length after the second time window is finished (the second transmitting power is raised by the first step length to obtain third transmitting power), and the first device sends the signal in the third transmitting power and the first beam direction (optional); if the first device receives the second device's signal (which may be threshold-based energy detection, or demodulated to information) within a second time window, the first device continues to transmit signals at the second transmit power and in the first beam direction (optional). If the number of power increases reaches the threshold value, the first device sends a signal in the first transmission power and the first beam direction (optional).

In the possible implementation manner, after the number of times of power boosting reaches a threshold value, the first device sends a signal at the first transmission power.

In a possible implementation manner, in the above process, if a signal sent by the second device is received, an active period timer is started, and before the active period timer expires, the signal is sent at the current transmission power; if the signal sent by the second equipment is received before the activation period timer is overtime, restarting the activation period timer; and if the signal sent by the second equipment is not received before the activation period timer is overtime, the signal is sent after the first step length is increased by the current transmitting power.

For example, if a first device receives a signal from a second device within a first time window, a first active period timer is started, and before the active period timer expires, the first device transmits a signal at a first transmit power and in a first beam direction; restarting the active period timer if the first device receives a signal from the second device before the active period timer expires; if the first device does not receive the second device's signal before the activation period timer expires, the first device sends a signal in the first beam direction (optional) at the second transmit power after the activation period timer expires.

If the first device receives a signal of the second device in the second time window, starting an active period timer, and before the active period timer expires, the first device sends a signal in the first beam direction at the second transmission power; restarting the active period timer if the first device receives a signal from the second device before the active period timer expires; if the first device does not receive the second device's signal before the activation period timer expires, the first device transmits a signal in the first beam direction (optionally) at the third transmit power after the activation period timer expires.

In a possible implementation manner, in the above implementation manner, after the number of times of power boosting reaches the threshold value, the beam direction may also be adjusted. Therefore, in this possible implementation manner, the first device sends a signal to the second device according to the configuration parameter of the first target transmission mode, including the following steps:

step 1, the first device sends signals with a first transmission power and a first beam direction.

Step 2, if the signal sent by the second device is not received in the first time window, after the first time window is finished, the first transmitting power is increased by a first step length to obtain a second transmitting power, and the signal is sent in the second transmitting power and the first beam direction;

step 3, if the signal sent by the second device is not received in a second time window, after the second time window is finished, the second transmitting power is increased by a first step length to obtain a third transmitting power, and the signal is sent in the third transmitting power and the first beam direction;

step 4, if the number of times of power increase reaches a threshold value, and a signal sent by the second device is still not received, sending a signal in the first transmitting power and the second beam direction, if a signal sent by the second device is not received in a received first time window, after the first time window is finished, increasing the first transmitting power by a first step length to obtain a second transmitting power, and sending a signal in the second transmitting power and the second beam direction until a signal sent by the second device is received in an nth time window or the number of times of power increase reaches the threshold value, wherein n is an integer greater than or equal to 1;

and 5, if the number of times of power increase reaches a threshold value and the signal sent by the second equipment is not received, sending the signal in the first sending power and the third beam direction, and repeating the steps until the number of times of power increase in all the beam directions reaches the threshold value.

With the above possible implementation, the first device may determine the transmit power and beam direction of the power supply in a manner that polls for different transmit powers and beam directions, so that the effect of powering the second device may be increased.

In the foregoing implementation manner, optionally, the method further includes: if a signal sent by the second device is received, starting an active period timer, and sending the signal in the current transmitting power and beam direction before the active period timer is overtime; if the signal sent by the second equipment is received before the activation period timer is overtime, restarting the activation period timer; and if the signal sent by the second equipment is not received before the activation period timer is overtime, the power after the first step length is increased by the current transmitting power and the signal is sent in the current beam direction.

In the foregoing implementation manner, optionally, after the number of times of power increase in all beam directions reaches a threshold, the first device sends a signal in the first transmission power and the first beam direction.
