- Wireless perception refers to the perception of environmental information through wireless signals.
- Environmental information includes but is not limited to: the distribution, size, quantity, temperature of environmental objects, human movements and behaviors, and even human breathing frequency, heart rate, etc.
- the principle of wireless perception is to transmit wireless signals to the environment that needs to be perceived, and at the same time collect wireless signals reflected, scattered or multi-path transmitted by the environment at the receiving end. Since the collected wireless signals are involved in the environment, that is, The collected wireless signals carry environmental information.
- the environmental characteristics can be obtained through corresponding signal processing, so that the perceived environmental information can be reconstructed, such as identifying people and objects in the environment, detecting temperature, detecting human movements, and even breathing frequency, heart rate, etc.
- Wireless sensing is usually divided into: single-station sensing (monostatic) and dual-station sensing.
- single-station sensing refers to the base station or terminal actively sending a sensing signal, and the sensing signal is reflected by the sensed object and then received by the base station or terminal.
- single-station sensing can include base station-based single-station sensing (as shown in Figure 1a) and terminal-based single-station sensing (as shown in Figure 1b).
- Dual-station sensing refers to the base station or terminal actively sending a sensing signal, and the sensing signal is received by the other terminal or base station through a wireless channel.

- Wireless sensing positioning accuracy is usually described by the root mean square error ( ⁇ ) of distance, speed and angle measurements.
- Positioning accuracy depends on the wireless sensing waveform and antenna parameters (such as signal time width, bandwidth and beam width) on the one hand, and on the signal-to-noise ratio of the echo signal on the other hand.
- the calculation formula is shown in Table 1:
- E the energy of the signal
- N0 the noise power per unit bandwidth
- c the speed of light
- SNR the signal Noise ratio
- SNR E/N 0

- the transmission spectrum is dedicated, and the perception signal is sent by a large base station or an aircraft. It is not sensitive to the power consumption of the transmitted signal.
- the perception service has a relatively small demand for wireless resources (that is, it is believed that there are sufficient wireless resources), so 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.
- the "appropriate" power P_T for sending the perception signal.
- the device sending the perception signal is a terminal and the perception mode is a single-station mode, see Figure 2.
- 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.
- 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.
- 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, it also causes signaling consumption in the resource application and allocation process, and increases the latency of the perception service; and when the terminal is in an 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 allocation of wireless resources.
- RACH Random Access Channel

- the method and device (or terminal) are based on the same application concept. Since the principles of solving the problem by the method and device (or terminal) are similar, the implementation of the method and device (or terminal) can refer to each other, and the repeated parts will not be repeated.
- an embodiment of the present disclosure provides a signal processing method, comprising the following steps:
- Step 31 The terminal determines a first target received power value of the perception signal.
- the first target receiving power value is the expected target power value for receiving the perception signal (for example, the first target receiving power value can be represented by P0 target_UE ).
- P0 target_UE indicates 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 is attenuated and/or reflected by the air interface, and the terminal expects to receive the perception signal, then P0 target_UE indicates the expected target power value at which the terminal can receive the perception signal after the terminal sends the perception signal and the perception signal is attenuated and/or reflected by the air interface; or, when the terminal sends the perception signal, if other devices (such as other terminals or network devices, etc.) expect to receive the perception signal, then P0 target_UE indicates the expected target power value at which other devices can receive the perception signal.
- P0 target_UE can be understood as: for a certain perception service, from the perspective of the receiving device (such as a terminal or network device, etc.), when the power value of the perception signal is greater than or equal to the P0 target_UE , the relevant signal quality can meet the requirements of the perception service quality, that is, the receiving device can effectively receive and calculate the perception signal, and output the perception result that meets the key indicator quality requirements.
- 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.
- 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.
- the numerical range of the first target received power value configured or indicated by the network device side may be -220dBm to -90dBm.
- the terminal may determine the first target received power value as 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.
- Step 32 The terminal determines a first transmit power value of the perception signal according to the first target receive power value.
- the terminal may consider the attenuation of the perceived signal during the transmission process and determine the first target receiving power.
- 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 transmitting end to the expected receiving end, a first parameter value related to the frequency domain resources occupied by the perception signal, and other power-related parameter values, etc., and the embodiments of the present disclosure are not limited thereto.
- the first transmit power value may 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 value of the transmit power required when sending the perception signal (for example, the first transmit power value may be represented by PT ToUE ).
- the first transmit power value may also be understood as the actual power value of sending the perception signal.
- PT ToUE indicates the transmission power that other devices need to meet when sending the perception signal, so as to satisfy that the power of the terminal receiving the perception signal is greater than or equal to P0 target_UE ; or, after the terminal sends the perception signal, the perception signal undergoes air interface attenuation and/or reflection, and the terminal expects to receive the perception signal, PT ToUE indicates the transmission power that the terminal needs to meet when sending the perception signal, so as to satisfy that the power of the terminal receiving the perception signal after air interface attenuation and/or object reflection is greater than or equal to P0 target_UE ; or, when the terminal sends the perception signal, and other devices (such as other terminals or network devices, etc.) expect to receive the perception signal, PT ToUE indicates the transmission power that the terminal needs to meet when sending the perception signal, so as to satisfy that the power of other devices receiving the perception signal is greater than or equal
- Step 33 The terminal determines a first wireless resource according to the first transmit power value.
- the terminal can determine the first wireless resource according to the relationship between the first transmission power value and the reference power value. For example, when PT ToUE is greater than or equal to the reference power value, it means that the transmitted perception signal has a relatively large interference on other devices. At this time, the network device side can allocate the transmission and/or reception resources of the perception signal to reduce the interference to other devices. When PT ToUE is less than the reference power value, it means that the transmitted perception signal has a relatively small interference on other devices. At this time, the terminal can determine the transmission transmission and/or reception resources of the perception signal by itself to reduce the signaling overhead and reduce the transmission delay of the perception signal.
- the other devices here may refer to network devices (such as gNB or perception servers, etc.), or or other terminals.
- Step 34 The terminal sends and/or receives the perception signal on the first wireless resource.
- 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.
- the terminal determines, according to the first target received power value, a first transmit power value of the perception signal, including but not limited to one of the following methods:
- 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 frequency domain resources occupied by the perception signal.
- the terminal can determine the first transmit power value according to the first target receive power value and the first set; wherein the first set may include the path loss value of the first path, the first parameter value related to the frequency domain resources occupied by the perception signal, or may also include other power-related parameter values, etc. That is, the terminal can determine the first transmit power value according to 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 according to the first target receive power value, the path loss value of the first path, the first parameter value, and other power-related parameter values, and the embodiments of the present disclosure are not limited thereto.
