Furthermore, multiple systems may be combined (for example, a combination of LTE or LTE-A with 5G).

[0057] In the embodiments of the present disclosure, communication sensing technology involves sensing nodes and sensing targets in its main scenarios. A sensing target can be an object to be sensed, such as a vehicle, building, drone, or rainfall. A sensing node can be a node that needs to sense the sensing target by sending and / or receiving sensing signals. Examples include base stations, user equipment, and vehicle-mounted devices. A sensing node wants to sense information about the sensing target, such as its position relative to itself, including distance, angle, and speed.

[0058] In the embodiment of the present disclosure, the sensing modes for sensing the sensing target may include the following six modes. In different modes, the corresponding sensing nodes are also different.

[0059] In the embodiment of the present disclosure, the sensing nodes are between access network devices, including sensing mode 1 and sensing mode 2.

[0060] Among them, sensing mode 1 is that the access network equipment performs autonomous transmission and reception. For example, the gNB sends a sensing signal, the sensing signal is reflected after reaching the sensing target, and the gNB also receives the reflected sensing signal.

[0061] Sensing Mode 2 involves the transmission of sensing signals between different access network devices. For example, gNB A transmits a sensing signal, and gNB B receives it. For example, gNB A transmits a sensing signal, which is reflected after reaching the sensing target. Then, gNB B receives the reflected sensing signal.

[0062] In the embodiment of the present disclosure, the sensing nodes are between terminals, including sensing mode 3 and sensing mode 4.

[0063] Among them, perception mode 3 is that the terminal performs autonomous transmission and reception. For example, the UE sends a perception signal, the perception signal is reflected after reaching the perception target, and the UE also receives the reflected perception signal.

[0064] Sensing mode 4 is the transmission of sensing signals between different terminals, for example, UE A sends a sensing signal and UE B receives the sensing signal. For example, UE A sends a sensing signal, the sensing signal is reflected after reaching the sensing target, and then UE B receives the reflected sensing signal.

[0065] In the embodiment of the present disclosure, the perception node is between the access network device and the terminal, including perception mode 5 and perception mode 6.

[0066] Sensing mode 5 involves the UE sending a sensing signal and the gNB receiving it. For example, the UE sends a sensing signal, which is reflected after reaching the sensing target, and then the gNB receives the reflected signal.

[0067] Sensing Mode 6 involves the gNB sending a sensing signal and the UE receiving the sensing signal. For example, the gNB sends a sensing signal, the sensing signal reaches the sensing target and is reflected, and the UE then receives the reflected sensing signal.

[0068] It is understood that in various embodiments of the present disclosure, a sensing node for sending a sensing signal may be referred to as a first node, a sensing sending node, a sensing signal sending node, etc. In various embodiments of the present disclosure, a sensing node for receiving a sensing signal may be referred to as a second node, a sensing receiving node, a sensing signal receiving node, etc. The present disclosure does not limit the names of the above nodes.

[0069] However, in the above-mentioned different sensing modes, there is currently no consensus on how to adjust the power of the sensing node when sending and / or receiving the sensing signal.

The first device uses the transmit power used when the perception signal was last transmitted as the first power. The first device then transmits the first signal at the first power. It will be appreciated that in this embodiment, the first device may not receive the third information sent by other devices. Alternatively, the first device may not expect to receive the third information sent by other devices.

[0124] Of course, in each embodiment of the present disclosure, the first signal, second signal, third signal, fourth signal, etc. involved can all be considered as signals used to sense the sensing target. The difference lies in that different signals are sent with different transmission powers, or some signals are signals used to sense the sensing target after being reflected by the sensing target. It is understandable that for some signals used to sense the sensing target, when the transmission power changes or after being reflected by certain objects, new names can be used to represent them, such as the fifth signal, the sixth signal, etc., and this disclosure does not limit this.

[0173] In some embodiments, considering that the first signal may not be reflected by the sensing target, or the reflected third signal may not be received by the first device for some reason, step S2103 is optional. In other words, step S2103 may not be performed.

[0192] In some embodiments, the second device may generate the first information based on pre-configured information and send the first information to the first device.

[0201] In some embodiments, the name of the second information is not limited, and it can be, for example, "configuration information", "power configuration information", "increase power information", etc.

[0202] In some embodiments, the first device is terminal 101, and the second device may be a first network element. The first network element may be core network device 103, or the first network element is a network element for implementing a perception function.

For another example, the first network element may also directly send the second information to the terminal 101 through an interface or protocol between the first network element and the terminal.

[0204] In some embodiments, the first device is the terminal 101, and the second device may be the access network device 102. For example, the access network device 102 may send the second information to the terminal 101 through an interface or protocol between the access network device and the terminal.

[0207] For example, the first network element sends the second information to the access network device 102 through the interface or protocol between the first network element and the access network device.

[0208] In some embodiments, the first device and the second device are different access network devices. For example, the first device is a first access network device and the second device is a second access network device. For example, the first access network device can send the second information to the second access network device via an interface or protocol between different access network devices.

[0209] In some embodiments, the first device and the second device are the same access network device, and the first device can determine the second information based on pre-configured information without sending or receiving the second information.

[0210] In some embodiments, the second device may generate second information based on pre-configured information and send the second information to the first device.

[0211] Step S2106: Upon detecting that the first condition is met, the first device adjusts the first power to obtain a second power.

[0212] In some embodiments, when a first condition is met, the first device may be triggered to adjust the first power. For example, if the first value is positive, the first value is added to the first power to obtain the second power.

[0213] In some embodiments, if the first condition is met, the first device may adjust the first power. For example, if the first value is negative, the absolute value of the first value is reduced from the first power to obtain the second power.

[0214] In some embodiments, the first value can be determined by receiving second information sent by the access network device.

[0215] In some embodiments, the first value can be determined by receiving second information sent by a first network element. It is understood that the first network element can be a core network device, or the first network element is a network element for implementing a perception function. The second information sent by the first network element can be forwarded to the first device via an access network device, or sent directly to the first device. The core network device herein includes a perception function entity.

[0216] In some embodiments, the first value may be determined based on a second rule.

[0217] For example, the first value is a default value set in the second rule.

[0218] In some embodiments, the second rule may be referred to as a second preset rule, a second specific rule, a second designated rule, etc. The present disclosure does not limit the name of the second rule.

[0219] In some embodiments, the second rule may be predefined.

[0220] In some embodiments, the first value may be determined based on the first parameter and a rule associated with the first parameter.

[0221] In some embodiments, the first value can be determined in at least one of the following ways: based on the access network device configuration; based on the first network element device configuration; based on the second rule; based on the first parameter and the rule related to the first parameter.

[0222] In some embodiments, the first parameter is a parameter related to the first signal and / or the perception target.

[0223] In some embodiments, the name of the first parameter is not limited, and it can be, for example, "perception parameter", "power adjustment parameter", "perception signal parameter", "communication signal parameter", "perception target parameter", etc.

[0224] In some embodiments, the first parameter includes the frequency of the first signal. A rule related to the first parameter may be: the higher the frequency, the larger the first parameter; or the higher the frequency, the smaller the first parameter.

[0225] For example, the frequency point may be referred to as an absolute radio frequency channel number (ARFCN).

[0226] In some embodiments, the first parameter includes a bandwidth for transmitting the first signal. A rule related to the first parameter may be: the larger the bandwidth, the larger the first parameter; or the larger the bandwidth, the smaller the first parameter.

[0227] In some embodiments, the first parameter includes the target type of the perceived target. A rule related to the first parameter may be: the worse the perceived target's reflectivity, the larger the first parameter; or the worse the perceived target's reflectivity, the smaller the first parameter.

[0228] Different target types can have different reflectivity. For example, a target of type 1 can almost perfectly reflect the sensing signal, while a target of type 2 absorbs some of the sensing signal's energy and reflects the rest. This weakens the signal strength or quality of the sensing signal.

[0229] In some embodiments, the first parameter includes the distance between the sensing target and the first device. A rule related to the first parameter may be: the longer the distance, the larger the first parameter; or the longer the distance, the smaller the first parameter. The first device is configured to send and / or receive the first signal.

[0230] In some embodiments, the first parameter includes the size of the space occupied by the perception target. The rule related to the first parameter can be: the larger the space occupied by the perception target, the larger the first parameter; or the larger the space occupied by the perception target, the smaller the first parameter.

[0231] For example, if the perceived target 1 is a large building and the perceived target 2 is a car, the first parameter corresponding to the perceived target 1 will be greater than the first parameter corresponding to the perceived target 2.

[0232] In some embodiments, the first parameter includes the environment the target is in. A rule related to the first parameter may be: the more complex and severe the environment, the larger the first parameter; or the more complex and severe the environment, the smaller the first parameter.

[0233] For example, if the target environment 1 is experiencing a violent storm, while the target environment 2 is experiencing calm winds, no rain, and a temperature of approximately 20 degrees Celsius, the first parameter corresponding to environment 1 will often be greater than the first parameter corresponding to environment 2. Of course, the criteria for determining the complexity and severity of an environment can be set based on actual circumstances and are not limited in this disclosure.

[0234] In some embodiments, the first parameter includes a moving speed of the perceived target. A rule related to the first parameter may be: the faster the moving speed, the larger the first parameter; or the faster the moving speed, the smaller the first parameter.

[0235] In some embodiments, the first parameter includes a device type of the first device. The rule related to the first parameter may be: determining the corresponding first parameter based on whether the first device is a terminal or an access network device.

[0236] In some embodiments, the first parameter may include at least one of the following parameters: the frequency of the first signal; the bandwidth of sending the first signal; the target type of the perceived target; the distance between the perceived target and the first device; the size of the space occupied by the perceived target; the environment in which the perceived target is located; the moving speed of the perceived target; and the device type of the first device.

[0237] In some embodiments, the first condition is a condition for adjusting the first power.

[0238] In some embodiments, the first condition includes not receiving the third signal within a default time period.

[0239] In some embodiments, the first device may not receive the third signal within a default time period, and the first device increases the first power by a first value to obtain the second power.

[0240] For example, the first device may not receive the third signal reflected by the sensing target within a default time period. The first device increases the first power by a first value to obtain a second power.

[0241] In some embodiments, the default time period can be determined by receiving first information sent by the access network device.

[0242] In some embodiments, the default time period can be determined by receiving first information sent by a first network element. It is understood that the first network element can be a core network device, or the first network element is a network element used to implement a perception function. The first information sent by the first network element can be forwarded to the first device via an access network device, or sent directly by a core network device. The core network device herein includes a perception function entity.

[0243] In some embodiments, the default time period may be determined based on a first rule.

[0244] For example, the first time window is a default value set in the first rule.

[0245] In some embodiments, the first rule may be referred to as a first preset rule, a first specific rule, a first designated rule, etc. The present disclosure does not limit the name of the first rule.

[0246] In some embodiments, the first rule may be predefined.

[0247] In some embodiments, the default time period may be determined in at least one of the following ways: based on access network device configuration; based on core network device configuration; or based on a first rule.

[0248] In some embodiments, the first condition includes a signal strength of the received third signal being less than a first threshold.

[0249] In some embodiments, when the signal strength of the third signal received by the first device is less than a first threshold, the first device increases the first power by a first value to obtain a second power.

[0250] In some embodiments, the first condition includes a signal quality of the received third signal being less than a second threshold.

[0251] In some embodiments, the signal quality of the third signal received by the first device may be less than a second threshold, and the first device may increase the first power by a first value to obtain a second power.

[0252] In some embodiments, the first condition includes an inability to accurately measure the third signal.

[0253] In some embodiments, if the first device cannot accurately measure the third signal, the first device may increase the first power by the first value to obtain the second power. The inability to accurately measure the third signal may be due to at least one of the following: the RSRP of the third signal is less than an RSRP threshold; the RSRQ of the third signal is less than an RSRQ threshold; or the SINR of the third signal is less than an SINR threshold.

[0254] In some embodiments, the first device may determine or judge whether the first condition is met.

[0255] In some embodiments, the determination or judgment can be performed by a value represented by 1 bit (0 or 1), or by a true or false value (Boolean value) represented by true or false, or by comparison of numerical values ​​(for example, comparison with a predetermined value), but is not limited thereto.

[0256] In some embodiments, the first device transmits a first signal using a first beam at a first power, and the first device transmits a second signal using the first beam or a second beam, wherein the first beam and the second beam are different beams.

[0257] In some embodiments, a first device transmits a second signal using a first beam. The first device increases a first power used when the first signal was most recently transmitted using the first beam by a first value, thereby obtaining a second power corresponding to the first beam.

[0258] For example, the first device may make adjustments for each (per) beam. Different beams may correspond to different beam directions. The first device may, for one beam, increase the transmit power by a first value each time a perception signal (for example, including the first signal) is retransmitted. 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 transmit power of the second time beam 1 is used to transmit the perception signal and the transmit power of the first time beam 1 is used to transmit the perception signal may be delta_21. The first value between the transmit power of the third time beam 1 is used to transmit the perception signal and the transmit power of the second time beam 1 is used to transmit the perception signal may be delta_32. The delta_21 and delta_32 may be the same or different.

[0259] Of course, the first and second times of using beam 1 to send a perception signal are not necessarily consecutive. For example, the first device sends a perception signal eight times in a row. Beam 1 is used for the first, third, fifth, and seventh times, and beam 2 is used for the second, fourth, sixth, and eighth times. Beam 1 and beam 2 can be adjusted independently. The first and third times of using beam 1 to send a perception signal can be considered the first and second times of using beam 1 to send a perception signal.

[0260] For example, the power used for transmitting the perception signal for the first time using beam 1 is P0_1, i.e., P0_1 is the initial transmit power for transmitting the perception signal using beam 1. The power used for transmitting the perception signal for the second time using beam 2 is P0_2, i.e., P0_2 is the initial transmit power for transmitting the perception signal using beam 2. P0_1 and P0_2 can be the same or different. The power used for transmitting the perception signal for the third time using beam 1 is P0_1 + delta3_1, and the power used for transmitting the perception signal for the fourth time using beam 2 is P0_2 + delta4_2. The power used for transmitting the perception signal for the fifth time using beam 1 is P0_1 + delta3_1 + delta5_3, and the power used for transmitting the perception signal for the sixth time using beam 2 is P0_2 + delta4_2 + delta6_4. And so on.

[0261] It can be seen that each time the first device performs power adjustment, it increases the power based on the previous transmit power of the same beam. It is not necessarily based on the most recent transmit power. This is because the beam that last sent the perception signal may be a different beam than the beam that is currently sending the perception signal.

[0262] 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.

[0263] In some embodiments, the first device transmits a second signal using a second beam. The term "second signal" may also be used interchangeably with "a first signal transmitted based on the second power," which is not limited in this disclosure.

[0264] The first device increases the first power used when the first signal was most recently transmitted using the first beam by a first value, thereby obtaining the second power corresponding to the second beam, where the first beam and the second beam are different.

[0265] For example, the first device may adjust the power using the first power used in the most recent transmission of the first signal, regardless of whether the beams are the same. That is, the same beam or a different beam may be used for each transmission of the perception signal. The first device increases the first power used in the most recent transmission of the first signal by the first value to obtain the second power. This does not consider whether the beam used in the most recent transmission of the first signal is the same beam used in the current transmission of the second signal.

[0266] Of course, the first value for adjusting the first power each time may be the same or different.

[0267] For example, the power of the first sent perception signal is P0_1, that is, P0_1 is the initial sent power of the perception signal. The power of the second sent perception signal is P0_1+delta2_1, and the power of the third sent perception signal is P0_1+delta2_1+delta3_2. And so on.

[0268] It can be seen that each time the first device adjusts the power, it no longer considers whether the beam used for sending the perception signal twice is the same, but directly increases the power based on the last transmission power.

[0269] It can be understood that the first value can be used to adjust the transmission power used for sending the perception signal last time.

[0270] In some embodiments, the first values ​​used when adjusting the power of the second signal transmitted based on different beams may be the same or different. In other words, the first values ​​added when transmitting the second signal based on the second power using different beams may be the same or different.

[0271] In some embodiments, a first device transmits a second signal using a first beam based on a 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 combinations. The second power is greater than the first power. It is understood that among the one or more first combinations, one or more first combinations include 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 determined as the second power for transmitting the second signal.

[0272] For example, different beams can be associated with different transmit powers. For example, beams include beam 1, beam 2, beam 3, and beam 4. Transmit powers include transmit power 1, transmit power 2, transmit power 3, transmit power 4, and transmit power 5. The power levels from transmit power 1 to transmit power 5 gradually increase. First combinations can be preconfigured, 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}, and so on. Each time a perception signal is transmitted, any first combination can be used, and the perception signal is transmitted based on the beams and transmit powers in that combination. The transmit power for each transmission must not be less than the transmit power of the previous perception signal transmission. There is no requirement that the beams used for different perception signal transmissions must be the same. The second power can be the lowest power value among the multiple first combinations corresponding to the first beam.

[0273] It should be noted that, in the above embodiments, for ease of understanding, different transmission times of the first signal are used to distinguish signals sent at different transmission powers for sensing a sensing target. However, it should be understood that in other embodiments, different names may be used to distinguish signals sent at different transmission powers for sensing a sensing target, such as the first signal and the second signal mentioned above. Of course, the specific signal names are merely exemplary and are not limiting in this disclosure.

[0274] In some embodiments, the terms "precoding", "precoder", "weight", "precoding weight", "quasi-co-location (QCL)", "transmission configuration indication (TCI) state", "spatial relation", "spatial domain filter", "transmission power", "phase rotation", "antenna port", "antenna port group", "layer", "the number of layers", "rank", "resource", "resource set", "resource group", "beam", "beam width", "beam angular degree", "antenna", "antenna element", "panel" and the like can be used interchangeably.

[0275] In some embodiments, the TCI state can be used to indicate which receive beams the terminal uses when receiving the physical downlink control channel (PDCCH) and / or the demodulation reference signal (DMRS) of the PDCCH, and / or the physical downlink shared channel (PDSCH) and / or the DMRS of the PDSCH. For example, the receive beams are the same as the synchronization signal and physical broadcast channel block (SSB) or channel state information reference signal (CSI-RS) sent by the network device. The TCI state can also be used to indicate which transmit beams the terminal uses when transmitting the physical uplink control channel (PUCCH) and / or the DMRS of the PUCCH, and / or the physical uplink shared channel (PUSCH) and / or the DMRS of the PUSCH. For example, the transmit beam corresponding to the receive beam of the SSB or CSI-RS sent by the receiving network device, or the same transmit beam as the SRS sent by the terminal. The beam refers to quasi-colocation (QCL) type D.

[0276] The network equipment may include access network equipment and / or core network elements.

[0277] In some embodiments, the beam may also be replaced by DL TCI state, UL TCI state, SL TCI state, joint TCI state or spatial relation information, etc.

[0278] In some embodiments, terms such as "certain", "preset", "preset", "setting", "indicated", "a certain", "any", and "first" can be interchangeable. "Specific A", "preset A", "preset A", "setting A", "indicated A", "a certain A", "any A", and "first A" can be interpreted as A pre-specified in a protocol, etc., or as A obtained through setting, configuration, or indication, etc., or as specific A, a certain A, any A, or first A, etc., but not limited to this.

[0279] Step S2107: The first device sends a second signal.

[0280] In some embodiments, the first device sends the sensing signal again according to the second power after power adjustment, that is, the first device sends the second signal.

[0281] The optional implementation of step S2107 can refer to the optional implementation of step S2102 in Figure 2 and other related parts in the embodiment involved in Figure 2, which will not be repeated here.

[0282] In some embodiments, after step S2107, any one or more of steps S2104, S2105, and S2106 may be repeatedly executed.

[0283] Step S2108: The first device receives the fourth signal.

[0284] In some embodiments, the first device may receive a fourth signal reflected by the sensing target, wherein the fourth signal may be a signal of the second signal reflected by the sensing target.

[0285] In some embodiments, if the power is not adjusted, the second signal may be the same signal as the first signal. In this case, the fourth signal may be the same signal as the third signal.

[0286] In some embodiments, the first device may measure a reflected signal after the sensing signal is reflected, such as the fourth signal and / or the third signal, and obtain corresponding parameters. It is understood that the parameters are parameters obtained by measuring the fourth signal and / or the third signal. These parameters may be referred to as measurement parameters, etc., and this disclosure does not limit the names of these parameters.

[0287] Take the case of sending the second signal and receiving the fourth signal as an example:

[0288] In some embodiments, the measured parameter may include RSRP of the fourth signal.

[0289] In some embodiments, the measured parameter may include a reference signal receiving power per path or a reference signal receiving power of the ith path (RSRPP) of the fourth signal.

[0290] In some embodiments, the measured parameter may include a reference signal received quality (RSRQ) of the fourth signal.

[0291] In some embodiments, the measured parameter may include a signal to interference plus noise ratio (SINR) of the fourth signal.

[0292] In some embodiments, the measured parameter may include an angle of arrival of the fourth signal.

[0293] In some embodiments, the measured parameter may include a departure angle of the second signal.

[0294] In some embodiments, the measured parameter may include an arrival time of the fourth signal.

[0295] In some embodiments, the measured parameter may include a time difference of arrival of the fourth signal.

[0296] The arrival time difference may be the difference between the arrival time of the fourth signal at the first device and a preset reference time. For example, the fourth signal arrives at the first device at time A, and the reference time may be time X. The arrival time difference may be the difference between time A and time X. Alternatively, the arrival time difference may be the difference between the arrival times of the fourth signal, after different second signals sent by the first device are reflected by the sensing target and then arrive at the first device. For example, the fourth signal 1 arrives at the first device at time C, and the fourth signal 2 arrives at the first device at time D. The arrival time difference may be the difference between time C and time D.

[0297] In some embodiments, the measured parameter may include a reception-send time difference, wherein the reception-send time difference is the difference between the time when the fourth signal is received and the time when the second signal is sent.

[0298] In some embodiments, the measured parameter may include a distance between the sensing target and the first device.

[0299] In some embodiments, the measured parameter may include a distance between the sensing target and the third device.

[0300] In some embodiments, the measured parameter may include a direction angle of the perceived target relative to the first device.

[0301] In some embodiments, the measured parameter may include a moving speed of the perceived target.

[0302] In some embodiments, the measured parameter may include a Doppler frequency shift of the fourth signal.

[0303] In some embodiments, the measured parameters may include at least one of the following: RSRP of the fourth signal; RSRQ of the fourth signal; SINR of the fourth signal; angle of arrival of the fourth signal; angle of departure of the second signal; time of arrival of the fourth signal; time difference of arrival of the fourth signal; time difference of reception and transmission; distance between the perceived target and the first device; distance between the perceived target and the third device; direction angle of the perceived target relative to the first device; moving speed of the perceived target; Doppler frequency deviation of the fourth signal.

[0304] In some embodiments, the at least one parameter obtained by the first device measuring the fourth signal may be reported to other devices, such as at least one of a terminal, an access network device, and the first network element.

[0305] In some embodiments, the at least one parameter obtained by measuring the fourth signal by the first device can be reported to other devices. For example, it can be reported to at least one of the terminal, the access network device and the first network element. Of course, in the case where the first device and the other device are both terminals, the first device can send the at least one parameter obtained by measuring the fourth signal to the other device. Although "reporting" can usually be understood as uplink sending, in this disclosure, "reporting" can be used interchangeably with "sending". "Reporting" can also be considered to include the sending of SL, which is not limited in this disclosure.

[0306] For example, the first device is terminal 101. The first device may report the at least one parameter obtained by measuring the fourth signal to at least one of another terminal, the access network device, and the first network element. The other terminal may be a third device or another terminal different from the first device or the third device.

[0307] For another example, if the first device is access network device 102, the first device may transmit the at least one parameter obtained by measuring the fourth signal to at least one of another access network device and the first network element. The other access network device may be a third device, or another access network device different from the first device and the third device.

[0308] In some embodiments, the aforementioned embodiments for measuring the fourth signal are also applicable to measuring the third signal in step S2103. For the specific implementation process, reference can be made to the description of measuring the fourth signal, except that the fourth signal is replaced by the third signal, and the second signal is replaced by the first signal. This disclosure will not elaborate further here.

[0309] In some embodiments, after receiving the fourth signal, the first device may measure the fourth signal to achieve perception of the perception target.

[0310] In some embodiments, sensing the perception target may include determining a distance of the perception target.

[0311] In some embodiments, sensing the perception target may include determining a direction of the perception target.

[0312] In some embodiments, sensing the perception target may include determining a moving speed of the perception target.

[0313] In some embodiments, sensing the perception target may include determining a location of the perception target.

[0314] In some embodiments, sensing the perception target may include determining a state of the perception target.

[0315] In some embodiments, sensing the perception target may include determining a target type of the perception target.

[0316] In some embodiments, sensing the perception target may include determining an environment in which the perception target is located.

[0317] In some embodiments, sensing the perception target may include determining the size of a space occupied by the perception target.

[0318] In some embodiments, perceiving a perception target may further include at least one of the following: determining the distance of the perception target; determining the direction of the perception target; determining the moving speed of the perception target; determining the position of the perception target; determining the state of the perception target; determining the target type of the perception target; determining the environment in which the perception target is located; and determining the size of the space occupied by the perception target.

[0319] Of course, in other embodiments, the perception of the perception target may also include any information related to the perception target, which is not limited in this disclosure.

[0404] In some embodiments, the first condition includes at least one of the following: the second signal is not received within a default time period; the signal strength of the received second signal is less than a first threshold; the signal quality of the received second signal is less than a second threshold.

[0405] In some embodiments, the default time period is determined by at least one of the following methods: receiving first information sent by an access network device or terminal, the first information is used to configure the default time period; receiving first information sent by a first network element, the first network element is a network element used to implement the perception function; determined based on a first rule.

[0406] In some embodiments, the first value is determined by at least one of the following methods: receiving second information sent by an access network device or terminal, the second information is used to configure the first value; receiving second information sent by a first network element, the first network element is a network element used to implement a perception function; determining based on a second rule; determining based on a first parameter and rules related to the first parameter.

[0408] Step S3403: Send a second signal at a second power.

[0409] The optional implementation method of step S3403 can refer to the optional implementation method of step S2107 in Figure 2, the optional implementation method of step S3106 in Figure 3a, the optional implementation method of step S3205 in Figure 3b, the optional implementation method of step S3304 in Figure 3c, and other related parts in the embodiment involved in Figure 2, other related parts in the embodiment involved in Figure 3a, other related parts in the embodiment involved in Figure 3b, and other related parts in the embodiment involved in Figure 3c, which will not be repeated here.

[0410] In some embodiments, after step S3403, the process further includes sensing the target. For example, the first device uses a fourth signal that reflects the second signal from the target to sense the target. In some embodiments, the process further includes receiving the fourth signal, which is a reflection of the second signal from the target, and measuring the fourth signal to obtain one or more measurement parameters. These measurement parameters can be transmitted to other devices for further information collection and action decision-making. For specific implementation, please refer to the optional embodiments described in the aforementioned step S2108.

[0411] In some embodiments, the fourth signal is measured to obtain at least one of the following parameters: RSRP of the fourth signal; reference signal received power RSRPP of the i-th path of the fourth signal, where i is a positive integer; reference signal received quality RSRQ of the fourth signal; signal-to-interference-and-noise ratio SINR of the fourth signal; angle of arrival of the fourth signal; angle of departure of the second signal; time of arrival of the fourth signal; time difference of arrival of the fourth signal, where the time difference of arrival is the difference between the time when the fourth signal is received and a preset reference time, or the time difference of arrival is the difference between the times when different fourth signals are received; time difference between receiving and sending the second signal and the fourth signal; distance between the perceived target and the first device; direction angle of the perceived target relative to the first device; moving speed of the perceived target; Doppler frequency deviation of the fourth signal.

[0412] Next, the present disclosure will describe the above solution with more detailed embodiments.

[0413] 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 default rule.

[0414] In some embodiments, the configuration may be a gNB configuration or an awareness function entity configuration or a UE indication via a sidelink.

[0415] 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.

[0416] In some embodiments, in the second step, the sensing node transmits the sensing signal using the initial transmission power, and then adjusts the transmission power to facilitate further transmission. The adjustment method is as follows:

[0417] In some embodiments, if the perception signal sending node cannot accurately receive the reflected perception signal within a certain period of time, or the signal strength or signal quality of the received perception signal is lower than a threshold value, the perception signal sending node will increase the transmission power by a delta value before sending it.

[0418] The threshold value may be a network configuration or a default value specified by the protocol.

[0419] In some embodiments, this time within a certain period of time may also be a network configuration or a default value specified by a protocol.

[0420] The delta value can be a network configuration, a default value specified by the protocol, or a value calculated based on certain parameters and a specified rule.

[0421] In some embodiments, the parameters may be related to the frequency of the perception signal (the higher the frequency, the larger the delta), bandwidth (the larger the bandwidth, the larger the delta), perception target type (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.

[0422] The power adjustment can be performed per beam, or it can be increased directly regardless of whether the beams are the same.

[0423] In some embodiments, per-beam power adjustment means that for each retransmission in the same beam direction, the power is increased by delta for each retransmission. The delta value can vary between transmissions. For example, the delta value for the second transmission can be different by 21% compared to the first, and by 32% compared to the third. This does not mean that the same beam must be used for consecutive transmissions. Rather, it means that beam 1 can be used for consecutive transmissions, or beam 1 can be used for the 1st, 3rd, 5th, or 7th transmissions, and beam 2 for the 2nd, 4th, 6th, and 8th transmissions. However, other power adjustments are performed independently for beams 1 and 2. For example, the power of beam 1 for the first transmission is P0_1 (beam 1's initial power), and the power of beam 2 for the second transmission is also P0_2 (beam 2's initial power; the initial powers 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. Each time, the power is increased based on the last transmitted power of the same beam, not the most recent transmitted power, because the most recent transmission power might be of a different beam.

[0424] Regardless of whether the beam is the same, the power is increased based on the most recent transmission. This means that the beam can vary with each retransmission, but the power is increased based on the most recent transmission power, regardless of whether the beam is the same. Similarly, the delta can be the same or different between transmissions.

[0425] Select some beam and power combinations to send, for example, beams are beam1, beam2, beam3, beam4, and the power is P0, P1, P2, P3, P4 gradually increasing. Then select some combinations to send, such as {P0, beam1}, {P0, beam3}, {P1, beam2}, {P2, beam4}, {P3, beam1}, {P4, beam3}... In this case, the transmitted power cannot be less than the previous transmission power, but the beam can change.

[0426] In some embodiments, the above embodiment is primarily applicable to the autonomous transmission and reception mode, including the sensing mode of UE autonomous transmission and reception and gNB autonomous transmission and reception. It is not limited to the other four modes.

[0427] In some embodiments, the perception signal involved 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.

[0428] In some embodiments, the awareness functional entity is part of the core network.

[0429] 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 / receive / send time difference, distance, moving speed, Doppler frequency deviation, etc.

[0430] In some embodiments, the above embodiments are applicable to the UE being in RRC_connected, RRC_inactive or RRC_idle state.
