Description

Signal processing method, device and terminal

[0001] This disclosure claims priority to the Chinese patent application filed with the China Patent Office on June 16, 2023, with application number 202310716651.X and application name “Signal Processing Method, Device and Terminal,” the entire contents of which are incorporated by reference into this disclosure. Technical Field

[0002] The present disclosure relates to the field of communication perception technology, and in particular to a signal processing method, device, and terminal. Background Art

[0003] In the evolution of communication technology, Integrated Sensing and Communication (ISAC) is an important candidate for evolutionary features. During the sensing process, a sensing device can actively transmit a sensing signal and perform environmental sensing based on an echo signal, or it can perform environmental sensing based on received sensing signals or echo signals. When a sensing device transmits a sensing signal, it is necessary to consider the signal's transmission power and transmission resources (here, "transmission" includes sending and / or receiving, and transmission resources include time domain resources and / or frequency domain resources). Theoretically, a higher transmission power of the sensing signal improves the precision and accuracy of the sensing result, while a lower transmission power reduces the precision and accuracy of the sensing result. However, a higher transmission power of the sensing signal increases interference with other communication devices, hindering inter-device air interface coexistence. For example, when a terminal is used as a sensing device, when the wireless resources used to transmit the sensing signal are shared by the terminal and a network device (such as a base station), the base station allocates the wireless resource locations for all sensing signals. This minimizes interference between signals between devices. However, the application and allocation process of sensing resources requires signaling interaction between the base station and the terminal, which results in new wireless resource consumption and increases the latency of the sensing service.

Based on the embodiments of the present disclosure, all other embodiments obtained by ordinary technicians in this field without making any creative efforts shall fall within the scope of protection of the present disclosure.

[0157] The following describes the related technologies involved in this disclosure:

[0158] 1. Basic Concepts of ISAC

[0159] The basic concept of ISAC is to introduce wireless sensing into wireless mobile communications. Wireless sensing refers to the use of wireless signals to perceive environmental information. This information includes, but is not limited to, the distribution, size, quantity, and temperature of environmental objects, human movements and behavior, and even breathing rate and heart rate. Wireless sensing works by transmitting wireless signals to the environment to be perceived and simultaneously collecting the wireless signals that have been reflected, scattered, or transmitted through multiple paths at the receiving end. Because the collected wireless signals have been subjected to the environment, they carry environmental information. After receiving the wireless signals, which have been reflected, scattered, or transmitted through multiple paths, appropriate signal processing is performed to obtain environmental characteristics, allowing the reconstruction of perceived environmental information. This includes identifying people and objects in the environment, detecting temperature, detecting human movements, and even breathing and heart rate.

[0160] Wireless sensing is generally categorized into monostatic and dual-station sensing. Monostatic sensing involves a base station or terminal actively transmitting a sensing signal, which is then reflected by the sensing object and received by the base station or terminal. For example, monostatic sensing can include base station-based monostatic sensing (as shown in Figure 1a) and terminal-based monostatic sensing (as shown in Figure 1b). Dual-station sensing involves a base station or terminal actively transmitting a sensing signal, which is then received by the other terminal or base station via a wireless channel. For example, dual-station sensing can include terminal-to-terminal dual-station sensing (i.e., UE-UE dual-station sensing, as shown in Figure 1c), base station-to-base station dual-station sensing (i.e., gNB-gNB dual-station sensing, as shown in Figure 1d), terminal-to-base station dual-station sensing (i.e., UE-gNB dual-station sensing, as shown in Figure 1e), and base station-to-terminal dual-station sensing (i.e., gNB-UE dual-station sensing, as shown in Figure 1f). Furthermore, wireless sensing can also include interactive sensing, where a terminal or base station actively transmits a sensing signal, which is then received by the base station or terminal without passing through a sensing object, as shown in Figure 1g.

[0161] 2. Wireless sensing accuracy

[0162] Wireless sensing positioning accuracy is typically described using the root mean square error (σ) of distance, velocity, and angle measurements. Positioning accuracy depends on both the wireless sensing waveform and antenna parameters (such as signal duration, bandwidth, and beamwidth) and the signal-to-noise ratio of the echo signal. The calculation formula is shown in Table 1:

[0163] Table 1

[0164] Where E is the energy of the signal, N0 is the noise power per unit bandwidth, c is the speed of light, SNR is the signal-to-noise ratio: SNR = E / N0, and τ is the signal duration (uncompressed pulse width): τ = MT r .

[0165] As can be seen from Table 1 above, the variables that the sensing device can control for the accuracy of wireless sensing are: signal bandwidth and transmission power (i.e., signal-to-noise ratio). The larger the transmission signal bandwidth and the greater the transmission power, the higher the wireless sensing accuracy.

[0166] 3. Perceive the signal transmission power and transmission resources

[0167] In radar sensing systems, the transmission spectrum is dedicated, and the sensing signals are transmitted by large base stations or aircraft. They are not sensitive to the power consumption of the transmitted signals. At the same time, it is believed that the sensing service has a relatively small demand for wireless resources (that is, it is believed that there are sufficient wireless resources). Therefore, there is no limit on the transmission power (such as transmitting at maximum power), and there is no need for a wireless resource allocation process.

[0168] In order to meet the requirements of the perception service quality indicators and reduce interference to other devices, it is necessary to determine the "appropriate" power P_T for sending the perception signal. For example, when the device sending the perception signal is a terminal and the perception mode is a single-station mode, see Figure 2. Regarding the transmission power P_T of the perception signal, a larger transmission power P_T can increase the value of the received power P_R, thereby improving the precision and accuracy of the perception signal. However, a larger transmission power P_T will cause interference to other devices and reduce the working time of the terminal. Therefore, it is necessary to determine the "appropriate" transmission power P_T.

[0169] In addition, regarding the resource location (including time domain and frequency domain) for sending perception signals: If all perception signals are allocated by network devices, although mutual interference between devices can be avoided to the greatest extent, the resource application and allocation process also causes signaling consumption, while increasing the latency of perception services; and when the terminal is in the idle state, the terminal needs to go through the Random Access Channel (RACH) process to enter the connected state before it can interact with the network device to apply for the allocation of wireless resources.

[0170] The present disclosure provides a signal processing method, apparatus, and terminal to address the current issues of high resource consumption and high latency in sensory signal transmission. The method and apparatus (or terminal) are based on the same patent application. Since the principles underlying the issues addressed by the method and apparatus (or terminal) are similar, their implementations can be referenced in conjunction with each other, and any repetitions will not be repeated.

[0171] As shown in FIG3 , an embodiment of the present disclosure provides a signal processing method, comprising the following steps:

[0172] Step 31: The terminal determines a first target received power value of the perception signal.

[0173] Optionally, the first target received power value is an expected target power value for receiving the perception signal (for example, the first target received power value may be P0 target_UE For example, when a perception signal is sent to another device (such as another terminal or network device), and the terminal expects to receive the perception signal, then P0 target_UE That is, it represents the expected target power value at which the terminal can receive the perception signal; or, after the terminal sends the perception signal, the perception signal undergoes air interface attenuation and / or reflection process, and the terminal expects to receive the perception signal, then P0 target_UEThat is, it means that after the terminal sends the perception signal, the terminal can receive the expected target power value of the perception signal after the perception signal is attenuated by the air interface and / or reflected by the object; or, when the terminal sends the perception signal, other devices (such as other terminals or network devices, etc.) expect to receive the perception signal, then P0 target_UE That is, it indicates the expected target power value at which other devices can receive the sensing signal.

[0174] Here, P0 target_UE It can be understood that for a certain sensing service, from the perspective of the receiving device (such as a terminal or network device, etc.), the power value of the sensing signal is greater than or equal to the P0 target_UE When the relevant signal quality can meet the requirements of the perception service quality, that is, the receiving end device can effectively receive and calculate the perception signal and output the perception result that meets the quality requirements of the key indicators.

[0175] Optionally, the first target received power value is configured or indicated by the network device side, or the first target received power value is agreed upon by a protocol. For example: in the case where the first target received power value is configured or indicated by the network device side, the network device may send a first indication message to the terminal, and the first indication message is used to indicate the first target received power value. For example, the numerical range of the first target received power value configured or indicated by the network device side may be -220dBm to -90dBm. When the network device side does not configure or indicate the first target received power value, the terminal may determine the first target received power value to be a default value based on the protocol agreement, such as setting the default value to -110dBm, etc. The embodiments of the present disclosure are not limited to this.

[0176] Step 32: The terminal determines a first transmit power value of the perception signal according to the first target receive power value.

[0177] For example, the terminal may compensate for the first target receive power value by taking into account the attenuation of the perception signal during transmission to obtain a first transmit power value of the perception signal. The attenuation of the perception signal during transmission includes, but is not limited to, at least one of the following: a path loss value of the perception signal from the signal transmitter to the intended receiver, a first parameter value related to the frequency domain resources occupied by the perception signal, and other power-related parameter values, although the embodiments of the present disclosure are not limited thereto.

[0178] Optionally, the first transmit power value can be understood as: when the power of the receiving end device receiving the perception signal is greater than or equal to the first target receive power value, the transmit power value required when sending the perception signal (for example, the first transmit power value can be PT ToUE). Or the first transmission power value can also be understood as the actual power value of sending the perception signal. For example: when a perception signal is sent to other devices (such as other terminals or network devices, etc.), if the terminal expects to receive the perception signal, then PT ToUE Indicates the transmission power that other devices need to meet when sending perception signals to ensure that the power of the terminal receiving the perception signal is greater than or equal to P0 target_UE Or, after the terminal sends a perception signal, the perception signal undergoes air interface attenuation and / or reflection process, and the terminal expects to receive the perception signal, then PT ToUE That is, it represents the transmission power that the terminal needs to meet when sending the perception signal, so that after the perception signal is attenuated by the air interface and / or reflected by the object, the power of the perception signal received by the terminal is greater than or equal to P0 target_UE Or, when the terminal sends a perception signal, other devices (such as other terminals or network devices, etc.) expect to receive the perception signal, then PT ToUE That is, it indicates the transmission power that the terminal needs to meet when sending the perception signal to ensure that the power of other devices receiving the perception signal is greater than or equal to P0 target_UE .

[0179] Step 33: The terminal determines a first wireless resource according to the first transmit power value.

[0180] For example, the terminal may determine the first wireless resource based on the relationship between the first transmit power value and the reference power value. ToUE When the power is greater than or equal to the reference power value, it means that the sent sensing signal has a relatively large interference on other devices. In this case, the network device side can allocate the sending and / or receiving resources of the sensing signal to reduce the interference on other devices. ToUE When the power level is less than the reference power value, the transmitted sensing signal has minimal interference with other devices. In this case, the terminal can independently determine the transmission and / or reception resources for the sensing signal to reduce signaling overhead and transmission latency. The "other devices" here can refer to network devices (such as gNBs or sensing servers) or other terminals.

[0181] Step 34: The terminal sends and / or receives the perception signal on the first radio resource.

[0182] In the above scheme, the terminal determines the first sending power value for sending the perception signal based on the first target receiving power value of the received perception signal, and determines the first wireless resource for sending and / or receiving the perception signal based on the first sending power value, so as to send and / or receive the perception signal on the first wireless resource. This can reduce the signaling overhead of the sending and / or receiving resources for the perception signal allocated by the network device, and reduce the transmission delay of the perception signal, thereby solving the current problems of high resource consumption and high delay in the transmission of the perception signal.

[0183] Optionally, the terminal determines the first transmit power value of the perception signal according to the first target receive power value, including but not limited to one of the following methods:

[0184] Method 1: The terminal determines the first transmit power value based on the first target receive power value and a first set, where the first set includes at least: a path loss value of a first path and a first parameter value related to the frequency domain resources occupied by the perception signal.

[0185] It should be noted that the terminal can determine the first transmit power value based on the first target receive power value and the first set; wherein the first set may include the path loss value of the first path, a first parameter value related to the frequency domain resources occupied by the perception signal, or may also include other power-related parameter values. In other words, the terminal can determine the first transmit power value based on the first target receive power value, the path loss value of the first path, and the first parameter value; or the terminal can also determine the first transmit power value based on the first target receive power value, the path loss value of the first path, the first parameter value, and other power-related parameter values, etc., but the embodiments of the present disclosure are not limited to this.

[0186] For example, taking the example of the terminal determining the first transmit power value based on the first target receive power value, the path loss value of the first path, and the first parameter value, the specific method for determining the first transmit power value is as follows: determining the first transmit power value based on the sum of the first target receive power value, the path loss value of the first path, and the first parameter value, as shown in the following formula:

[0187] Among them, PL ue-ue is the path loss value of the first path, is the first parameter value, here It can also be understood as the function value of a function related to the frequency domain resources occupied by the perception signal.

[0188] Mode 2: The terminal determines the first transmit power value according to the first target receive power value and a second set, where the second set includes at least a path loss value of the first path.

[0189] It should be noted that the terminal may determine the first transmit power value based on the first target receive power value and the second set; the second set may include the path loss value of the first path, or may also include other power-related parameter values. In other words, the terminal may determine the first transmit power value based on the first target receive power value and the path loss value of the first path; or the terminal may determine the first transmit power value based on the first target receive power value, the path loss value of the first path, and other power-related parameter values, etc., but the embodiments of the present disclosure are not limited to this.

[0190] For example, taking the example of the terminal determining the first transmit power value based on the first target receive power value and the path loss value of the first path, the specific method for determining the first transmit power value is as follows: determining the first transmit power value based on the sum of the first target receive power value and the path loss value of the first path, as shown in the following formula: PT ToUE =P0 target_UE +PL ue-ue

[0191] Among them, PL ue-ue is the path loss value of the first path.

[0192] Optionally, the first path is a path from the transmitter of the perception signal to the first signal receiver, and the first signal receiver is the expected receiver of the perception signal. For example, when the terminal expects to receive the perception signal when the other device sends the perception signal (that is, the other device is the transmitter of the perception signal and the terminal is the first signal receiver), the first path is the path that the perception signal travels from the other device to the terminal; or, after the terminal sends the perception signal, the perception signal undergoes air interface attenuation and reflection, and the terminal expects to receive the perception signal (that is, the terminal is both the transmitter of the perception signal and the first signal receiver), the first path is the path that the perception signal travels from the terminal after passing through the reflecting object to the terminal; or, when the terminal sends the perception signal, other devices expect to receive the perception signal (that is, the terminal is the transmitter of the perception signal and the other device is the first signal receiver), the first path is the path that the perception signal travels from the terminal to the other device.

[0193] Optionally, the path loss value of the first path is less than or equal to a preset path loss value; wherein the preset path loss value is determined by at least the maximum sensing distance supported by the sensing service, the RCS, and the transmission frequency band of the sensing signal. In other words, the preset path loss value can be determined by the maximum sensing distance supported by the sensing service, the RCS, and the transmission frequency band of the sensing signal, or by the maximum sensing distance supported by the sensing service, the RCS, the transmission frequency band of the sensing signal, and other path loss-related parameters, and the embodiments of the present disclosure are not limited thereto.

[0194] For example, taking the case where the preset path loss value is determined by the farthest sensing distance supported by the sensing service, RCS, and the transmission frequency band of the sensing signal, the preset path loss value may be specifically determined by the following formula: PL max =PL(L)+PL(β*L)+-10lg(RCS)

[0195] Among them, PL max is the preset path loss value. PL() is the distance-related path loss calculation formula. For example, PL(L) is the path loss value at distance L, PL(L) = 32.4 + 17.3Log 10 (L)+20Log 10 (f c ), f c is the carrier frequency of the sensing signal; PL(β*L) is the path loss value of the distance β*L, and β*L is the path length of the reflected echo.

[0196] For example, if the path loss value of the first path is less than or equal to the preset path loss value, the path loss value of the first path may be determined based on the actual measured path loss value of the first path and the preset path loss value. For example, the path loss value of the first path is determined by the following formula: PL ue-ue =min(αPL ue-SS ,PL max )

[0197] Among them, PL ue-ue is the path loss value of the first path; PL ue-SS The measured path loss value, for example: the terminal cannot obtain the PL ue-SS (If no relevant perception signal has been sent yet), the PL ue-SS Set to infinity; PL max is a preset path loss value, and α is a weighting factor. For example, the weighting factor may be indicated by a network device side, or determined based on a perceived service, but the embodiments of the present disclosure are not limited thereto.

[0198] Optionally, the terminal determining, according to the first transmit power value, a first radio resource includes:

[0199] The terminal determines a second target received power value of the perception signal;

[0200] The terminal determines a second transmit power value of the perception signal according to the two target receive power values;

[0201] The terminal determines a first wireless resource according to a magnitude relationship between the first transmit power value and the second transmit power value.

[0202] Optionally, the second target received power value is a power threshold value at which the perception signal generates interference (for example, the second target received power value can be represented by P0target_gNB). For example, the P0target_gNB is the power value of the perception signal sent by the terminal, which is received by the network device after air interface attenuation and / or reflection. Here, since the network device is not the expected receiving end of the perception signal, that is, when the perception signal is received by the network device, it interferes with the network device. In other words, the P0target_gNB can be understood as: the interference level caused to the network device (such as a serving base station, etc.) when the terminal sends a perception signal.

[0203] Optionally, the second target received power value is configured or indicated by the network device side, or the second target received power value is agreed upon by a protocol. For example: in the case where the second target received power value is configured or indicated by the network device side, the network device may send a second indication information to the terminal, and the second indication information is used to indicate the second target received power value. For example, the second target received power value configured or indicated by the network device may be an absolute value (for example, the numerical range of the second target received power value may be -220dBm to -90dBm), or the second target received power value configured or indicated by the network device may be a power threshold value for sensing interference generated by the signal and a target power value P0 for communication. target_C The difference between them is called offset, for example: P0target_gNB=P0 target_C -offset; where P0 target_C It can be a target power value indicated in a communication system in the related art. When the network device side does not configure the second target receive power value, the terminal can determine the second target receive power value as a default value based on the protocol agreement, such as setting the default value to -120dBm, etc., but the embodiments of the present disclosure are not limited to this.

[0204] Optionally, the second transmission power value can be understood as: when the receiving end device receives the perception signal, the transmission power value of the perception signal when it is sent (for example, the second transmission power value can be in the form of PT TogNBAlternatively, the second transmit power value may also be understood as a reference power value for sending the perception signal, that is, when sending the perception signal, avoiding interference to other devices (here, the other devices are non-desired receiving devices of the perception signal).

[0205] Optionally, the terminal determines, according to the second target received power value, a second transmit power value of the perception signal, including but not limited to one of the following methods:

[0206] Method 1: The terminal determines the second transmit power value based on the second target receive power value and a third set, where the third set includes at least: a path loss value of the second path and a first parameter value related to the frequency domain resources occupied by the perception signal.

[0207] It should be noted that the terminal may determine the second transmit power value based on the second target receive power value and a third set; wherein the third set may include the path loss value of the second path, a first parameter value related to the frequency domain resources occupied by the perception signal, or may also include other power-related parameter values. In other words, the terminal may determine the second transmit power value based on the second target receive power value, the path loss value of the second path, and the first parameter value; or the terminal may also determine the second transmit power value based on the second target receive power value, the path loss value of the second path, the first parameter value, and other power-related parameter values, etc., but the embodiments of the present disclosure are not limited to this.

[0208] For example, taking the example of the terminal determining the second transmit power value based on the second target receive power value, the path loss value of the second path, and the first parameter value, the specific method for determining the second transmit power value is as follows: determining the second transmit power value based on the sum of the second target receive power value, the path loss value of the second path, and the first parameter value, as shown in the following formula:

[0209] Among them, PL ue-gNB is the path loss value of the second path, is the first parameter value, here It can also be understood as the function value of a function related to the frequency domain resources occupied by the perception signal.

[0210] Method 2: The terminal determines the second transmit power value according to the second target receive power value and a fourth set, where the fourth set includes at least: a path loss value of the second path, the first parameter value, and a first gain value.

[0211] It should be noted that the terminal may determine the second transmit power value based on the second target receive power value and a fourth set; wherein the fourth set may include a path loss value of the second path, a first parameter value related to the frequency domain resources occupied by the perception signal, a first gain value, or may further include other power-related parameter values. In other words, the terminal may determine the second transmit power value based on the second target receive power value, the path loss value of the second path, the first parameter value, and the first gain value; or the terminal may also determine the second transmit power value based on the second target receive power value, the path loss value of the second path, the first parameter value, the first gain value, and other power-related parameter values, but the embodiments of the present disclosure are not limited to this.

[0212] For example, taking the example of the terminal determining the second transmit power value based on the second target receive power value, the path loss value of the second path, the first parameter value, and the first gain value, the specific method for determining the second transmit power value is as follows: determining the second transmit power value based on the sum of the second target receive power value, the path loss value of the second path, the first parameter value, and the first gain value, as shown in the following formula:

[0213] Among them, PL ue-gNB is the path loss value of the second path, g(θ d ) is the first gain value, is the first parameter value, here It can also be understood as the function value of a function related to the frequency domain resources occupied by the perception signal.

[0214] Mode three: The terminal determines the second transmit power value according to the second target receive power value and a fifth set, where the fifth set includes at least a path loss value of the second path.

[0215] It should be noted that the terminal may determine the second transmit power value based on the second target receive power value and the fifth set; wherein the fifth set may include the path loss value of the second path, or may also include other power-related parameter values. In other words, the terminal may determine the second transmit power value based on the second target receive power value and the path loss value of the second path; or the terminal may also determine the second transmit power value based on the second target receive power value, the path loss value of the second path, and other power-related parameter values, etc., but the embodiments of the present disclosure are not limited to this.

[0216] For example, taking the example of the terminal determining the second transmit power value based on the second target receive power value and the path loss value of the second path, the specific method for determining the second transmit power value is as follows: the second transmit power value is determined based on the sum of the second target receive power value and the path loss value of the second path, as shown in the following formula: PT TogNB =P0target_gNB+PL ue-gNB

[0217] Among them, PL ue-gNB is the path loss value of the second path.

[0218] Optionally, the second path is a path from the transmitter of the perception signal to the second signal receiver, and the second signal receiver is a receiver interfered by the perception signal, or the second signal receiver can also be understood as an undesired receiver of the perception signal. For example, when a terminal sends a perception signal, the perception signal is received by a network device after air interface attenuation and / or reflection (that is, the terminal is the transmitter of the perception signal, and the network device is the second signal receiver), the second path is the path that the perception signal passes through from the terminal to the network device.

[0219] Optionally, the path loss value of the second path may be determined by a first reference signal;

[0220] The first reference signal includes at least one of the following:

[0221] Reference signals configured for sensing services;

[0222] Reference signal used to determine PUCCH transmit power;

[0223] Reference signal for determining PUSCH transmit power;

[0224] Synchronization signal block used to obtain MIB.

[0225] For example: the terminal can be indexed as q d The reference signal (ie, the first reference signal, that is, the index number is q d The reference signal may be a reference signal configured for the perception service, or when the network device does not specifically configure a reference signal for the perception service, the index number is q d The reference signal can also be used to calculate the PUCCH transmission power reference signal q d , or the reference signal q used to calculate the PUSCH transmit power d , or for obtaining the synchronization signal block of the MIB, etc.). For example, the terminal may obtain the index number q according to the network device. dThe difference between the transmission power of the reference signal and the reception power of the reference signal is determined as the path loss value of the second path, and the unit of the path loss value of the second path is dB.

[0226] Optionally, the first gain value is a gain value representing a beam direction difference between a signal sent by the second signal receiving end and received by the terminal and a perception signal received by the terminal. For example, the first gain value is less than or equal to a reference gain value. The reference gain value may be indicated by a network device or determined based on a beam gain, etc., and the present disclosure is not limited thereto.

[0227] For example, as shown in FIG4 , the terminal can calculate a gain value based on the beam direction difference between the signal sent by the second signal receiving end (note: in FIG4 , it refers to the network device) and the perception signal received by the terminal. Considering that the unit of the gain value is dB, it is necessary to perform an equivalent conversion on the beam direction difference when calculating the gain value, for example, according to Equivalently converted into the gain value corresponding to the above beam direction difference, the first gain value can be determined by the following formula:

[0228] Among them, g(θ d ) is the first gain value.

[0229] θ d is the beam direction difference between the signal sent by the second signal receiving end and the perception signal received by the terminal. d =θ ue-ue -θ gNB-ue , where θ ue-ue That is, the beam direction of the terminal receiving the sensing signal, θ gNB-ue That is, the beam direction of the signal sent by the second signal receiving end received by the terminal. d = 0, indicating that the two beams have the same direction, θ d =π means the two beams are in opposite directions. ue-ue and θ gNBgue The terminal can determine the beam direction based on the signal sent by the receiving network device and the received perception signal.

[0230] θ XdB is the angle value corresponding to the gain attenuation of XdB, where X is a constant value (for example, X is set to 3, and of course X can also be set to other values, and the embodiments of the present disclosure are not limited thereto). Here θ XdB Or X can be configured or indicated by the network device side; or, θ XdB Or X is set according to beam gain, etc., and the embodiments of the present disclosure are not limited thereto.

[0231] Gm is the reference gain value. Here G m It can also be indicated by the network device side or determined according to the beam gain, for example, setting G m =20dB, but the embodiments of the present disclosure are not limited thereto.

[0232] It should be noted that: the above description θ d , is essentially the difference between the optimal beam direction (i.e., the direction with the greatest gain) of the transmission beam when the terminal sends the perception signal with directionality and the directional angle of the perception signal to the second signal receiving end (e.g., the network device). Considering the reciprocity of the spatial channel, θ in the embodiment of the present disclosure is d It is described by the directional difference between the two receiving beams.

[0233] Optionally, when determining the first transmit power value and / or determining the second transmit power value, the first parameter value used may be determined in the following manner:

[0234] The first parameter value is determined by the number of RBs occupied by the perception signal in the frequency domain;

[0235] or,

[0236] The first parameter value is determined by the number of REs occupied by the perception signal in the frequency domain.

[0237] For example, the first reference value may be determined based on a function related to the number of RBs in the frequency domain occupied by the perception signal (for example, the function uses the number of RBs as a variable, and the value of the function is the first parameter value), or the first reference value may be determined based on a function related to the number of REs in the frequency domain occupied by the perception signal (for example, the function uses the number of REs as a variable, and the value of the function is the first parameter value), etc. The embodiments of the present disclosure are not limited thereto.

[0238] Optionally, the first parameter value is determined by the number of RBs occupied by the perception signal in the frequency domain, including:

[0239] The first parameter value is determined by the following formula:

[0240] in, is the first parameter value, μ is the subcarrier spacing configuration parameter, is the number of RBs occupied by the perception signal in the frequency domain.

[0241] For example, when resource allocation is performed in units of RB in the frequency domain of the sensing signal, the above formula can be used: Determine the first parameter value. The unit of the first parameter value is decibel milliwatt (dBm). In order to schedule flexibility, the function of the first parameter value can also be Multiply by a factor a d , the factor a d It can be determined based on the perceived service, or can be configured or indicated by the network device side, or can be determined by the terminal itself based on the perceived service quality requirements, etc., and the embodiments of the present disclosure are not limited thereto.

[0242] Optionally, the first parameter value is determined by the number of REs occupied by the perception signal in the frequency domain, including:

[0243] The first parameter value is determined by the following formula:

[0244] in, is the first parameter value, μ is the subcarrier spacing configuration parameter, is the number of REs occupied by the perception signal in the frequency domain.

[0245] For example, when resource allocation is performed in units of RE in the frequency domain of the perception signal, the above formula can be used: Determine the first reference value. 12 REs form one RB. The unit of the first parameter value is decibel milliwatt (dBm). For scheduling flexibility, the function of the first parameter value can also be Multiply by a factor a d , the factor a d It can be determined based on the perceived service, or can be configured or indicated by the network device side, or can be determined by the terminal itself based on the perceived service quality requirements, etc., and the embodiments of the present disclosure are not limited thereto.

[0246] Optionally, as an implementation manner, the terminal determining the first radio resource according to a magnitude relationship between the first transmit power value and the second transmit power value includes:

[0247] When the first transmit power value is greater than or equal to the second transmit power value, the terminal determines the wireless resource indicated by the network device side as the first wireless resource; for example, the network device side indicates a specific wireless resource as the first wireless resource.

[0248] and / or,

[0249] When the first transmission power value is less than the second transmission power value, the terminal determines the first wireless resource by itself; for example, the terminal determines the first wireless resource by itself from a plurality of wireless resources configured or indicated by a network device side.

[0250] Optionally, as another implementation manner, the terminal determining the first radio resource according to a magnitude relationship between the first transmit power value and the second transmit power value includes:

[0251] The terminal determines a radio resource acquisition mode according to a magnitude relationship between the first transmit power value and the second transmit power value;

[0252] The terminal determines the first wireless resource according to the wireless resource acquisition method.

[0253] For example, the resource acquisition method may include but is not limited to at least one of the following:

[0254] The first acquisition method is that the network device side indicates the first wireless resource; for example, the network device side indicates a specific wireless resource as the first wireless resource.

[0255] The second acquisition method is that the terminal determines the first wireless resource by itself; for example, the terminal determines the first wireless resource by itself from multiple wireless resources configured or indicated by the network device side. For example,

[0256] Optionally, the terminal determining the first radio resource according to a magnitude relationship between the first transmit power value and the second transmit power value includes:

[0257] When the first transmission power value is greater than or equal to the second transmission power value, the terminal determines that the wireless resource acquisition method is the first acquisition method; wherein, the first acquisition method is that the network device side indicates the first wireless resource; for example: the network device side indicates that a specific wireless resource is the first wireless resource.

[0258] and / or,

[0259] When the first transmission power value is less than the second transmission power value, the terminal determines the wireless resource acquisition method as the second acquisition method; wherein, the second acquisition method is that the terminal determines the first wireless resource by itself; for example: the terminal determines the first wireless resource by itself from multiple wireless resources configured or indicated by the network device side.

[0260] For the first acquisition method (Mode-1), it can also be called the determination mode of restricted uplink resources. For example, as shown in Figure 5a, the power of the perception signal sent by the terminal or other device when it reaches the network device is higher than a certain threshold value (such as greater than or equal to P0target_gNB). At this time, if the terminal determines the wireless resource for sending the perception signal by itself, it may cause greater interference to the uplink reception of the network device. In order to reduce this interference, the terminal can use the Mode-1 to determine the first wireless resource for sending and / or receiving the perception signal, that is, the network device side indicates a specific wireless resource (for example, when the specific wireless resource is allocated to the terminal on the network device side for perception signal transmission, it is no longer allocated to other terminals, so as to avoid interference with the uplink reception of the network device) as the first wireless resource. At this time, the terminal only sends the perception signal on the wireless resource specified by the network device side.

[0261] For the second acquisition method (Mode-2), it can also be called the free uplink resource determination mode. For example, as shown in Figure 5b, the power of the perception signal sent by the terminal or other device when it reaches the network device is lower than a certain threshold value (such as less than P0target_gNB). At this time, the interference level of the perception signal sent by the terminal to the base station is low, that is, the interference caused to the uplink reception of the network device is small. At this time, the terminal can use Mode-2 to determine the first wireless resource for sending and / or receiving the perception signal, that is, the terminal can select the wireless resource by itself in the resource set or resource pool of the perception signal configured or indicated by the network device. For example, the terminal can select any wireless resource in the resource set or resource pool to send and / or receive the perception signal without the network device specifying the wireless resource process.

[0262] It should be noted that, in the embodiments of the present disclosure, when determining the first wireless resource based on the magnitude relationship between the first transmit power value and the second transmit power value; or determining the wireless resource acquisition method based on the magnitude relationship between the first transmit power value and the second transmit power value: the first transmit power value may adopt the above-mentioned method 1 or method 2 for determining the first transmit power value, and the second transmit power value may adopt the above-mentioned method 1, method 2, or method 3 for determining the second transmit power value. Optionally, considering that the same first parameter value is involved in the method 2 for determining the first transmit power value and the method 3 for determining the second transmit power value, the first wireless resource or the wireless resource acquisition method may be determined based on the magnitude relationship between the first transmit power value and the second transmit power value, etc., and the embodiments of the present disclosure are not limited to this.

[0264] The terminal sends a perception signal using the first transmit power value or the second transmit power value on a first radio resource;

[0267] The terminal sends a perception signal using the adjusted first transmit power value or the adjusted second transmit power value on the first radio resource.

[0268] Specifically, when the terminal is performing a sensing service (for example, when detecting a sensing object and tracking it), when the terminal sends the sensing signal on the first wireless resource, the transmission power PT of the sent sensing signal can be adjusted according to the actual detected reflection signal (or echo signal). ToUE For example, the terminal starts to send the perception signal from the initial transmit power P_T; wherein the initial transmit power P_T is the first transmit power value or the second transmit power value. Further, the terminal receives the reflected signal (or echo signal) of the perception signal and calculates the received power value P_R based on the reflected signal (or echo signal). The terminal gradually increases or decreases the transmit power P_T of the perception signal according to P_R until P_R and P_T are equal. target_UE The difference meets certain conditions (such as P_R and P0 target_UE The difference between them is within a first value range of delta1 to delta2, where delta1 and delta2 can be configured or indicated by the network device side).
