[0032] like Figure 2 As shown, an embodiment of the present application provides a signal sending method 200, which can be executed by a first device. In other words, the method can be executed by software or hardware installed on the first device. The method includes the following steps.
[0033] S202: The first device sends a signal based on a preset rule, where the preset rule includes at least one of the following: a first rule: the sending resources of the signal gradually increase; a second rule: the sending resources of the signal gradually decrease; a third rule: the sending resources of the signal remain unchanged.
[0034] In each embodiment of the present application, the first device is a signal sending device, and the first device can be a terminal or a network side device; the signal receiving device (second device) can also be a terminal or a network side device. Among them, the signaling transmission between the network side device and the terminal, and between the terminals can be through Radio Resource Control (RRC) signaling, Media Access Control Control Element (MAC CE) signaling, Layer 1 signaling or other newly defined signaling; the signaling transmission between network side devices can be through Xn interface signaling.
[0035] The transmission resources in this embodiment may include but are not limited to bandwidth, frequency domain density, time domain resource length, time domain density, power, number of transmitting antennas, etc.
[0036] In this embodiment, the first device may send a signal based only on the first rule; the first device may also send a signal based only on the second rule; the first device may also send a signal based on the first rule and the third rule, for example, starting from the moment the signal is sent, the sending resources of the signal gradually increase, and when the sending resources increase to a certain value, the sending resources of the signal remain unchanged; the first device may also send a signal based on the second rule and the third rule, for example, starting from the moment the signal is sent, the sending resources of the signal gradually decrease, and when the sending resources decrease to a certain value, the sending resources of the signal remain unchanged; the first device may also send a signal based on the first rule and the second rule, for example, starting from the moment the signal is sent, the sending resources of the signal gradually increase, and when the sending resources increase to a certain value, the sending resources of the signal gradually decrease; the first device may also send a signal based on a combination of the first rule, the second rule and the third rule, for example, starting from the moment the signal is sent, the sending resources of the signal gradually increase, and when the sending resources increase to a certain value, the sending resources of the signal remain unchanged, and after a certain period of time, the sending resources of the signal gradually decrease; and so on.
[0037] In this embodiment, the first device may spontaneously determine (adjust) the preset rule for sending the signal, and the first device may also notify the second device of the preset rule, or the preset rule is pre-agreed between the first device and the second device.
[0038] In this embodiment, the first device may also adjust the preset rule for sending the signal based on the feedback signaling of the second device.
[0039] Optionally, in various embodiments of the present application, the signal sent by the first device may be a perception signal, and the perception signal is used for perception measurement. This embodiment may send a perception signal according to the characteristics of the perception service to meet the measurement performance of basic perception measurements such as delay / distance, Doppler / speed, and angle.

For another example, the first device sends the perception signal according to the first rule, and the second device can continuously feedback whether the perception signal can meet the perception requirement. When the perception requirement can be met, the first device sends the perception signal according to the third rule, thereby reducing the signal transmission resource overhead.

Since the second device does not need to send feedback signaling, feedback signaling overhead is saved.

[0116] 2) Time domain behavior of reporting; for example, a: periodic reporting: reporting according to a specified time offset and / or period; b: semi-persistent reporting: after receiving a report start indication, reporting according to a specified period until a report stop indication is received; the report start indication is used to indicate the start of a corresponding perception report; the report stop indication is used to indicate the stop of reporting; c: aperiodic reporting: reporting at a specified time or when preset conditions are met.

[0119] In the above embodiments, the first indication information, the second indication information and the third indication information may be different signaling messages or the same signaling message.
[0120] Optionally, the method provided in each of the above embodiments further includes the following step: the first device receives first feedback information from a second device, where the second device is a receiving device of the signal, and the first feedback information includes at least one of the following items related to the signal:
[0121] 1) Stop sending an indication, when the first device receives the indication, it stops sending the perception signal. For example, the first device continues to send the perception signal based on the first rule, the second rule or the third rule, and the second device can calculate the expected perception result according to the perception signal resource received from the first device, and when there is no need to continue receiving the perception signal, the second device sends the termination sending indication to the first device.
[0122] 2) Continue to send the indication. When the first device receives the indication, it continues to send the perception signal. For example, it continues to send the perception signal according to the first rule, the second rule or the third rule mentioned above. In one embodiment, the first feedback information of the second device has only 1 bit, 0 represents termination of sending, and 1 represents continuation of sending. The target rule for the second device to send 0 or 1 is configured, for example, it is configured by the first device to the second device. The definition of the target rule can refer to the previous trigger condition, or be further expanded.
[0123] 3) A switching indication of the preset rule. When the first device receives the indication, it switches the preset rule used for sending the perception signal, for example, switching from the first rule to the third rule, that is, the perception signal sending resources are no longer increased, and the perception signal is sent unchanged according to the current configuration.
[0124] 4) Performance indicators, such as a perceived signal to interference plus noise ratio (SINR) or a signal to noise ratio (SNR), the first device determines whether a current perceived signal transmission resource configuration needs to be adjusted according to the perceived performance indicators.
[0125] 5) An indication of whether the performance index is met, and the first device determines whether the current perception signal sending resource configuration needs to be adjusted according to the indication. For example, when the first device sends a perception signal based on the first rule, if an indication that the perception performance index is met is received, the first device no longer continues to increase the perception signal sending resource, keeps the current perception signal resource configuration unchanged to send the perception signal, that is, changes to use the third rule to send the perception signal. Alternatively, when the first device sends a perception signal based on the second rule, if an indication that the perception performance index is met is received, the first device no longer continues to reduce the perception signal sending resource, keeps the current perception signal resource configuration unchanged to send the perception signal, that is, changes to use the third rule to send the perception signal.
[0126] 6) Start sending an indication, and the first device starts sending a perception signal according to the indication.
[0127] The perceived SNR and SINR will be explained below: the perceived SNR may be a ratio of the perceived target associated signal power to the noise power, and the perceived SINR may be a ratio of the perceived target associated signal power to the sum of the powers of noise and interference.
[0128] Taking radar detection as an example, the method for acquiring the power of the perceived target associated signal may be at least one of the following options:
[0129] 1) Based on the time delay one-dimensional graph obtained by fast Fourier Transform (FFT) processing of the echo signal in the fast time dimension, a constant false alarm rate detector (CFAR) is performed. The maximum amplitude sample point of the CFAR over-threshold is taken as the target sample point, and its amplitude is taken as the target signal amplitude to calculate the perceived target associated signal power, such as Figure 5 shown.
[0130] 2) Based on the delay-Doppler two-dimensional map obtained by 2D-FFT processing of the echo signal, the CFAR is used to calculate the perceived target associated signal power by taking the maximum amplitude sample point that exceeds the threshold of the CFAR as the target sample point and its amplitude as the target signal amplitude.
[0131] 3) CFAR is performed based on the delay-Doppler-angle three-dimensional graph obtained by 3D-FFT processing of the echo signal. The maximum amplitude sample point that exceeds the CFAR threshold is used as the target sample point, and its amplitude is used as the target signal amplitude to calculate the perceived target associated signal power.
[0132] In addition to the above method of using the maximum amplitude sample point of CFAR over-threshold as the target sample point, the method of determining the target signal amplitude can also be to use the maximum amplitude sample point of CFAR over-threshold and the average of several of its nearest over-threshold sample points as the target signal amplitude to calculate the perceived target associated signal power.
[0133] The method for obtaining the SNR / SINR of the echo signal may be at least one of the following options:
[0134] 1) Perform CFAR based on the time delay one-dimensional graph obtained by fast time dimension FFT processing of the echo signal, take the maximum amplitude sample point that exceeds the threshold of CFAR as the target sample point, and take its amplitude as the target signal amplitude. Take all the sample points in the one-dimensional graph that are ±ε sample points away from the target sample point as interference / noise sample points, and count their average interference / amplitude as interference / noise signal amplitude. Finally, calculate SNR / SINR with the target signal amplitude and interference / noise signal amplitude;
[0135] 2) Perform CFAR based on the Doppler one-dimensional image obtained by slow time dimension FFT processing of the echo signal, take the maximum amplitude sample point of CFAR over the threshold as the target sample point, and its amplitude as the target signal amplitude, take all the sample points in the one-dimensional image that are ±η sample points away from the target sample point as interference / noise sample points, and count their average amplitude as interference / noise signal amplitude, and finally calculate SNR / SINR with the target signal amplitude and interference / noise signal amplitude;
[0136] 3) Based on the delay-Doppler two-dimensional map obtained by 2D-FFT processing of the echo signal, CFAR is performed. The maximum amplitude sample point that exceeds the threshold of CFAR is taken as the target sample point, and its amplitude is taken as the target signal amplitude. All sample points in the two-dimensional map that are ±ε (fast time dimension) and ±η (slow time dimension) away from the target sample point are taken as interference / noise sample points, and their average amplitude is counted as the interference / noise signal amplitude. Finally, the SNR / SINR is calculated based on the target signal amplitude and the interference / noise signal amplitude;
[0137] 4) Perform CFAR based on the delay-Doppler-angle three-dimensional graph obtained by 3D-FFT processing of the echo signal. The sample point with the maximum amplitude that passes the CFAR threshold is taken as the target sample point, and its amplitude is taken as the target signal amplitude. All sample points in the three-dimensional graph that are ±ε (fast time dimension), ±η (slow time dimension), and ±δ (angle dimension) sample points away from the target sample point are taken as interference / noise sample points, and their average amplitude is counted as the interference / noise signal amplitude. Finally, the SNR / SINR is calculated using the target signal amplitude and the interference / noise signal amplitude.
[0138] In addition to the above method of using the maximum amplitude sample point of CFAR over-threshold as the target sample point, the target signal amplitude can also be determined by using the maximum amplitude sample point of CFAR over-threshold and the average of several adjacent over-threshold sample points as the target signal amplitude.
[0139] The method for determining the interference / noise sample points can also be further screening based on the interference / noise sample points determined above, and the screening method is: for the one-dimensional delay graph, remove several sample points near the delay of 0, and use the remaining interference / noise sample points as noise sample points; for the one-dimensional Doppler graph, remove several sample points near the Doppler of 0, and use the remaining interference / noise sample points as interference / noise sample points; for the two-dimensional delay-Doppler graph, remove the interference / noise sample points in the strip range composed of several points near the delay of 0 and the entire Doppler range, and use the remaining noise sample points as interference / noise sample points; for the three-dimensional delay-Doppler-angle graph, remove the interference / noise sample points in the slice range composed of several points near the time dimension 0, the entire Doppler range and the entire angle range, and use the remaining interference / noise sample points as interference / noise sample points.
