In some embodiments, the first signal sent by the first device may be used to sense a sensing target, wherein the sensing target may be considered as a target that needs to be sensed.

For example, the sensing target may be a building, a moving object, the external environment, etc. The external environment may include temperature, humidity, whether it is raining, etc.

It is understood that after the first signal is sent by the first device and reaches the sensing target, the first signal can be reflected by the sensing target so that the second device receives the reflected first signal. The second device can use the reflected first signal to perform measurement to achieve perception of the sensing target, such as positioning.

In some embodiments, the name of the first signal is not limited, and it may be, for example, "perception information", "first signal", "sensory information", "sensory signal", etc.

In some embodiments, the second device receives the sensing signal after being reflected by the sensing target.

Step S2105: The second device sends the first information to the first device.

In some embodiments, the second device sends the first information to the first device.

In some embodiments, the first device receives first information sent by the second device.

In some embodiments, the first information is used to determine a second power. The second power may be a power adjusted from the first power.

In some embodiments, the name of the first information is not limited, and it may be, for example, "indication information", "power indication information", "power adjustment indication", "power update information", etc.

In some embodiments, the second device receives the second information, and the second device can know the time domain position of the first device sending the first signal based on the second information. The second information received by the second device may be sent by the first device, or by a network device. The network device includes an access network device or a first network element. The first network element is a core network device, or the first network element may be a network element that implements a perception function. The core network device here includes a perception function entity. In other words, the second device can know when the first device sends the first signal based on the second information. The second device can send the first information to the first device at any time after the first device sends the first signal.

In some embodiments, in the case where the second device can normally receive the first signal, the first information can be sent after the second device receives the first signal. Of course, since the time taken for the first signal propagation process is usually very short, the case where the second device sends the first information before receiving the first signal can be ignored.

In some embodiments, if the second device knows the time domain location at which the first device sends the first signal, and the second device accurately receives the first signal, the second device may send the first information to the first device, so that the first device adjusts the first power based on the first information.

It can be understood that in this embodiment, the first power can be adjusted according to a preset rule.

In some embodiments, if the second device knows the time domain location of the first device sending the first signal, but the second device does not accurately receive the first signal, the second device may send first information to the first device, so that the first device adjusts the first power based on the first information.

It can be understood that in this embodiment, since the second device cannot accurately receive the first signal, the second device can determine that the first device sent the first signal, but it was not accurately received due to low power. Therefore, the second device can determine to adjust the first power so that the second device can accurately receive the first signal. In this embodiment, the second power determined by the first information can be configured considering that the second device cannot accurately receive the first signal.

In some embodiments, the second device knows the time domain position of the first device sending the first signal. The second device measures the first signal to obtain the signal strength of the first signal. If the signal strength of the first signal is less than the first threshold, the second device may send the first information to the first device, so that the first device can adjust the first power based on the first information. Optionally, in the case where the signal strength of the first signal is less than the first threshold, the second device may send the first information to the first device, so that the first device can adjust the first power based on the first information. Optionally, in response to the signal strength of the first signal being less than the first threshold, the second device may send the first information to the first device, so that the first device can adjust the first power based on the first information. Optionally, when the signal strength of the first signal is less than the first threshold, the second device may send the first information to the first device, so that the first device can adjust the first power based on the first information.

In some embodiments, the content indicated by the first information sent by the second device under different circumstances may be different. For example, when the signal strength of the first signal is less than the first threshold, the first information sent by the second device may indicate that the first value is increased to the first power, so that the first device sends the first signal based on the second power after adjusting the power, which can make the second device more likely to receive it. Among them, the first value may be a positive value. For another example, when the signal strength of the first signal is greater than or equal to the first threshold, the first information sent by the second device may indicate that the first value is increased to the first power to ensure that the second device can receive the first signal more accurately without generating more power consumption. Among them, the first value increased to the first power when the signal strength of the first signal is greater than or equal to the first threshold is different from the first value increased to the first power when the signal strength of the first signal is less than the first threshold.

For example, different first values may all be positive values. For example, when the signal strength of the first signal is greater than or equal to the first threshold, the first value added to the first power is less than the first value added to the first power when the signal strength of the first signal is less than the first threshold. Alternatively, when the signal strength of the first signal is greater than or equal to the first threshold, the first value added to the first power is greater than the first value added to the first power when the signal strength of the first signal is less than the first threshold.

For another example, different first values may have positive values or negative values. For example, when the signal strength of the first signal is greater than or equal to the first threshold, the first value added to the first power may be a negative value, and when the signal strength of the first signal is less than the first threshold, the first value added to the first power may be a positive value.

In some embodiments, the first information may also include an RSRP value of the first signal measured by the second device; or, the first information includes a second power value of the first signal to be sent by the first device next time; or, the first information indicates that the first power remains unchanged.

In some embodiments, it is of course not excluded that the first information sent by the second device under different circumstances indicates the same content.

In some embodiments, the first threshold may be a signal strength threshold. The first threshold may also be referred to as a "first strength threshold", "strength threshold", etc., and the present disclosure does not limit the name of the first threshold.

In some embodiments, the second device may determine or judge whether the signal strength of the first signal is less than a first threshold.

It can be understood that in this embodiment, since the signal strength of the first signal measured by the second device is low and does not reach the first threshold, the second device can determine that the first device sent the first signal, but it was not accurately received due to low power. Therefore, the second device can determine to adjust the first power so that the second device can measure the first signal with higher signal strength. In this embodiment, the second power determined by the first information can be configured in consideration of the low signal strength of the first signal measured by the second device.

In some embodiments, the second device knows the time domain position of the first device sending the first signal. The second device measures the first signal to obtain the signal quality of the first signal. If the signal quality of the first signal is less than the second threshold, the second device may send the first information to the first device, so that the first device can adjust the first power based on the first information. Optionally, in the case where the signal quality of the first signal is less than the second threshold, the second device may send the first information to the first device, so that the first device can adjust the first power based on the first information. Optionally, in response to the signal quality of the first signal being less than the second threshold, the second device may send the first information to the first device, so that the first device can adjust the first power based on the first information. Optionally, when the signal quality of the first signal is less than the second threshold, the second device may send the first information to the first device, so that the first device can adjust the first power based on the first information.

In some embodiments, the second threshold may be a signal quality threshold. The second threshold may also be referred to as a "quality threshold" or the like, and the present disclosure does not limit the name of the second threshold.

In some embodiments, the second device may determine or judge whether the signal quality of the first signal is less than a second threshold.

It can be understood that in this embodiment, since the signal quality of the first signal measured by the second device is low and does not reach the second threshold, the second device can determine that the first device sent the first signal, but it was not accurately received due to low power. Therefore, the second device can determine to adjust the first power so that the second device can measure the first signal with higher signal quality. In this embodiment, the second power determined by the first information can be configured in consideration of the low signal quality of the first signal measured by the second device.

In some embodiments, the second device does not receive the second information, which means that the second device does not know when the first device sends the first signal. Therefore, the second device sends the first information to the first device only when it receives the first signal.

For example, the first device increases the first power used when the first beam was used to send the first signal the last time by the first device by a first value, thereby obtaining the second power corresponding to the first beam.

For example, the first device may make adjustments for each (per) beam. Different beams may correspond to different beam directions. The first device may increase the transmission power by a first value for each retransmission of the first signal for a beam. Of course, the increased first value may be the same or different for different transmissions. For example, for beam 1, the first value between the transmission power of the first signal sent using beam 1 for the second time and the transmission power of the first signal sent using beam 1 for the first time may be delta_21. The transmission power of the first signal sent using beam 1 for the third time may be delta_21. The first value between the transmission power of the first signal transmitted for the second time using beam 1 may be delta_32. The delta_21 and delta_32 may be the same or different.

Of course, the first use of beam 1 to send the first signal and the second use of beam 1 to send the first signal are not necessarily two consecutive times of sending the first signal. For example, the first device sends the first signal 8 times in a row, wherein beam 1 is used for the 1st, 3rd, 5th, and 7th times of sending the first signal, and beam 2 is used for the 2nd, 4th, 6th, and 8th times of sending the first signal. Beam 1 and beam 2 can be adjusted independently. For the first use of beam 1 to send the first signal and the third use of beam 1 to send the first signal. It can be considered that the first use of beam 1 to send the first signal and the second use of beam 1 to send the first signal.

For example, the power of beam 1 used for sending the first signal for the first time is P0_1, that is, P0_1 is the initial transmission power of the first signal sent using beam 1. The power of beam 2 used for sending the first signal for the second time is P0_2, that is, P0_2 is the initial transmission power of the first signal sent using beam 2. P0_1 and P0_2 may be the same or different. The power of beam 1 used for sending the first signal for the third time is P0_1+delta3_1, and the power of beam 2 used for sending the first signal for the fourth time is P0_2+delta4_2. The power of beam 1 used for sending the first signal for the fifth time is P0_1+delta3_1+delta5_3, and the power of beam 2 used for sending the first signal for the sixth time is P0_2+delta4_2+delta6_4. And so on.

It can be seen that each time the first device performs power adjustment, it increases the power based on the last transmission power of the same beam. It is not necessarily increased based on the most recent transmission power. The reason is that the beam that sent the first signal most recently may be a different beam from the beam that sends the first signal this time.

It can be understood that the first value can be used to adjust the first power when the first signal is sent using the same beam.

In some embodiments, the first device uses the first beam or the second beam to send the first signal based on the second power. The first device increases the first power used when the first beam was used to send the first signal the last time by the first device by a first value, thereby obtaining the second power corresponding to the first beam or the second beam, wherein the first beam is different from the second beam.

For example, the first device may not consider whether the beam used in two adjacent transmissions of the first signal is the same, and directly use the first power used in the most recent transmission of the first signal for adjustment. That is, the same beam may be used for each transmission of the first signal, or a different beam may be used. The first device increases the first value based on the first power used in the last transmission of the first signal to obtain the second power. It does not consider whether the beam used in the last transmission of the first signal is the same beam as the beam used in the current transmission of the first signal.

Of course, the first value for adjusting the first power each time may be the same or different.

For example, the power of the first signal sent for the first time is P0_1, that is, P0_1 is the initial transmission power of the first signal. The power of the first signal sent for the second time is P0_1+delta2_1, and the power of the first signal sent for the third time is P0_1+delta2_1+delta3_2. And so on.

It can be seen that each time the first device performs power adjustment, it no longer considers whether the beam used for sending the first signal twice in a row is the same, but directly increases the power based on the last transmission power.

It can be understood that the first value can be used to adjust the transmission power used for sending the first signal last time.

In some embodiments, the first values used when adjusting the power of the first signal transmitted based on different beams may be the same or different. In other words, the first values added when transmitting the first signal based on the second power using different beams may be the same or different.

In some embodiments, the first device uses the first beam to send a first signal based on the second power. The first device determines one or more first combinations. Each first combination includes a beam and a power. The first device determines a second power corresponding to the first beam based on the first combination. The second power is greater than the first power. It can be understood that among the one or more first combinations, there is at least one first combination including the first beam and the second power. When there are multiple first combinations including the first beam and the second power, the second power with the smallest power value is selected as the second power used for sending the first signal this time.

For example, different beams may be associated with different transmit powers. For example, the beams include beam 1, beam 2, beam 3, and beam 4. The transmit powers include transmit power 1, transmit power 2, transmit power 3, transmit power 4, and transmit power 5. Among them, the power from transmit power 1 to transmit power 5 gradually increases. The first combination can be pre-configured, such as {transmit power 1, beam 1}, {transmit power 1, beam 3}, {transmit power 2, beam 2}, {transmit power 3, beam 4}, {transmit power 4, beam 2}, {transmit power 5, beam 3}... It can be seen that any first combination can be used each time the first signal is sent, and the first signal is sent based on the beam and transmit power in the combination. Among them, the transmit power each time can be not less than the transmit power of the last time the first signal was sent. There is no requirement for the same beam for sending the first signal at different times. The second power can be the power with the smallest power value among the multiple first combinations corresponding to the first beam.

In some embodiments, the first device may receive the first information sent by the second device within the first time window, and adjust the first power based on the power indicated by the first information to obtain the second power.

In some embodiments, the first information may directly indicate how much the transmit power is increased, decreased, or remains unchanged, or the first information may directly indicate the second power.

In some embodiments, the first information may instruct the second device to measure the RSRP of the first signal. The RSRP may be layer (layer, L) 1-RSRP. The RSRP may also be L3-RSRP after filtering for a period of time.

In some embodiments, "precoding", "precoder", "weight", "precoding weight", "quasi-co-location (QCL)", "transmission configuration indication (transmission configuration indication)" and "precoding weight" are used to indicate the transmission configuration of the transmission.

In some embodiments, the TCI state may be used to indicate which receive beams the terminal uses when receiving a physical downlink control channel (PDCCH) and/or a demodulation reference signal (DMRS) of a PDCCH, and/or a physical downlink shared channel (PDSCH) and/or a DMRS of a PDSCH. For example, the same receive beam as which synchronization signal/physical broadcast channel block (SSB) or channel state information reference signal (CSI-RS) sent by a network device is received by the terminal. The TCI state may also be used to indicate which transmit beams the terminal uses when transmitting a physical uplink control channel (PUCCH) and/or a DMRS of a PUCCH, and/or a physical uplink shared channel (PUSCH) and/or a DMRS of a PUSCH. For example, the transmission beam corresponding to the reception beam of the SSB or CSI-RS sent by the receiving network device, or the same transmission beam as the SRS sent by the terminal. The beam refers to quasi-colocation (QCL) type D.

In some embodiments, the beam can also be replaced by DL TCI state, UL TCI state, SL TCI state, joint TCI state or spatial relationship information.

In some embodiments, terms such as "certain", "preset", "preset", "set", "indicated", "some", "any", and "first" can be interchangeable, and "specific A", "preset A", "preset A", "set A", "indicated A", "some A", "any A", and "first A" can be interpreted as A pre-defined in a protocol, etc., or as A obtained through setting, configuration, or indication, etc., and can also be interpreted as specific A, some A, any A, or first A, etc., but is not limited to this.

Next, the present disclosure will describe the above solution with more detailed embodiments.

In some embodiments, in the first step, the perception signal sending node determines the initial transmission power of the perception signal based on a configuration or a default rule.

In some embodiments, the configuration may be a gNB configuration or an awareness function entity configuration or a UE indication via a sidelink.

In some embodiments, the configuration includes directly configuring the transmit power, or configuring the pathloss RS, or indicating the RSRP received by the perception signal receiving end.

For example, the sending node determines the sending power by measuring the RSRP value of the pathloss RS. If the RSRP value of the pathloss RS is large, the sending power can be small. Otherwise, the sending power needs to be large.

For example, the RSRP received by the sensing signal receiving end has a corresponding relationship with the transmission power. The larger the RSRP received by the sensing signal receiving end, the closer the distance between the transmitting node and the receiving end is, so the transmission power can be smaller.

In some embodiments, in the second step, the sensing node sends the sensing signal using the initial transmission power, and then adjusts the transmission power to facilitate re-sending, and the adjustment method is as follows:

In some embodiments, if the perception signal sending node does not receive the indication information sent by the perception signal receiving node within a time window, the perception signal sending node will increase the transmission power by a delta value before sending it.

The time window may be a network configuration or a default value specified by the protocol.

The delta value may be a network configuration, a default value specified by a protocol, or a value calculated based on certain parameters and a specified rule.

For example, the parameters may be related to the frequency of the perception signal (the higher the frequency, the larger the delta can be), bandwidth (the larger the bandwidth, the larger the delta can be), perception target type (if the perception target has poor transmission capability, the delta can be larger), distance range of the perception target (the longer the distance, the larger the delta can be), size range of the perception target (the larger the size, the larger the delta can be), perception environment, movement speed of the perception target, perception node type (UE or gNB), etc.

The power adjustment can be performed per beam, or it can be increased directly regardless of whether the beams are the same.

Per beam means that for the same beam direction, the power increases by delta for each retransmission, and the delta value can be different for different transmissions. For example, the delta_21 of the second transmission compared to the first transmission can be different from the delta_32 of the third transmission compared to the second transmission. This does not mean that the same beam must be used for multiple consecutive transmissions, but that beam 1 can be used for multiple consecutive transmissions, or beam 1 can be used for the 1st, 3rd, 5th, and 7th times, and beam 2 can be used for the 2nd, 4th, 6th, and 8th times. However, for beam 1 and beam 2, other power adjustments are performed independently. For example, the power of beam 1 used for the first time is P0_1 (the initial power of beam 1), and the power of beam 2 used for the second time is also P0_2 (the initial power of beam 2, and the initial powers of the two can be the same or different). The power of beam1 used for the third time is P0_1+delta_31, and the power of beam2 used for the fourth time is P0_2+delta_42. That is, each time the power is increased based on the last transmitted power of the same beam, not based on the most recent transmitted power, because the most recent transmission power may be a different beam.

Regardless of whether the beam is the same or not, the power is increased directly based on the power of the last transmission. This means that for each retransmission, the beam can change, and the power is increased based on the power of the last transmission, regardless of whether the beam is the same or not. Similarly, the delta can be the same or different for different transmissions.

Select some beam and power combinations to send, for example, beams are beam1, beam2, beam3, beam4, and powers are P0, P1, P2, P3, P4 and gradually increase. Then select some combinations to send, such as {P0, beam1}, {P0, beam3}, {P1, beam2}, {P2, beam4}, {P3, beam1}, {P4, beam3}... In this case, the power sent cannot be less than the last send power, but the beam can change.

In some embodiments, if the perception signal sending node receives the indication information sent by the perception signal receiving node within the time window, it can perform the next step according to the indication information.

For example, the indication information may indicate a power adjustment parameter, such as how much to increase, how much to decrease, or whether to remain unchanged, or indicate an RSRP value at a perceived receiving node, where the RSRP may be L1-RSRP or L3-RSRP filtered over a period of time.

In some embodiments, the indication information is sent as follows: If it is a mode of perception between different UEs, UE B can directly inform UE A through the interface between UEs, or UE B can forward it to UE A through the gNB. If it is a description of perception between gNBs, it is sent through the interface between gNBs.

There are different methods for sensing when a signal receiving node sends indication information:

Method 1: The perception signal receiving node knows the time when the perception signal sending node starts to send the perception signal (i.e., the time domain configuration information of the perception signal). Therefore, if the perception signal receiving node cannot accurately receive the perception signal within a period of time after this time, or the signal strength or signal quality of the received perception signal is lower than the threshold value, the perception signal receiving node knows that the perception signal sending node sent the perception signal, but it was not accurately received due to low power. Then, the perception signal receiving node can send indication information to the perception signal sending node after any perception signal sending time.

How does the sensing signal receiving node know the sensing signal sending time?

Between different UEs, the time domain configuration information of the perception signal can be notified through the interface between UEs, or by the gNB, or by the perception function entity: including period, time slot offset value, number of symbols, symbol starting position, etc.

Different gNBs can directly inform the time domain configuration information of the perception signal through the interface between gNBs or the perception function entity, including period, time slot offset value, number of symbols, symbol starting position, etc.

Method 2: The perception signal receiving node does not know the time when the perception signal sending node starts sending the perception signal, that is, the perception signal receiving node does not have the time domain configuration information of the perception signal. Then, only when the perception signal receiving node can accurately receive the perception signal or the signal strength or signal quality of the received perception signal is higher than the threshold value, it knows that the perception signal sending node has sent the perception signal. In this case, the indication information can be sent.

In some embodiments, the above embodiments are mainly applicable to the sensing modes between different UEs or between different gNBs, and are not limited to the other four modes.

In some embodiments, the perception signal in the above embodiments may be a PRS, an SRS, an SL-PRS, a PRS/SRS between base stations, or a new reference signal for perception.

In some embodiments, the awareness functional entity is part of the core network.

In some embodiments, the measurement values of the perceived signal include signal strength measurement values RSRP/RSRQ/SINR, angle measurement values arrival angle/departure angle, time measurement values arrival time difference/arrival time/receiving and sending time difference, distance, moving speed, Doppler frequency deviation, etc.

In some embodiments, the above embodiments are applicable to the UE being in RRC_connected, RRC_inactive or RRC_idle state.
