- sensing signal sending nodes and receiving nodes there are 6 basic sensing methods.
- Mode 1 Base station self-transmitting and self-receiving sensing.
- base station A sends a sensing signal and performs sensing measurement by receiving the echo of the sensing signal.
- Mode 2 Air interface sensing between base stations: At this time, base station B receives the sensing signal sent by base station A and performs sensing measurement.
- Mode 3 Uplink air interface perception: At this time, base station A receives the perception signal sent by terminal A and performs perception measurement.
- Mode 4 Downlink air interface perception: At this time, terminal B receives the perception signal sent by base station B and performs perception measurement.
- Terminals send and receive sensing autonomously.
- terminal A sends a sensing signal and performs sensing measurement by receiving the echo of the sensing signal.
- Mode 6 Sidelink perception between terminals: In this case, terminal B receives the perception signal sent by terminal A and performs perception measurement.
- the non-ideal factors that affect perceived performance mainly include:
- Time-frequency synchronization deviation Factors such as clock deviation at the transmitting and receiving ends and non-ideal synchronization lead to problems such as carrier frequency offset, sampling frequency offset, and symbol timing offset, which will affect the accuracy of velocity estimation or cause ranging ambiguity.
- Antenna/array amplitude and phase errors When using beamforming for perception, the beamforming amplitude and phase errors will cause the formed beam shape (beam gain, beam width, sidelobe level) to be inconsistent with the actual situation, which will lead to a decrease in accuracy when perceiving based on the channel information after beamforming, resulting in errors in angle and reflected power estimation, and even false detection.
- beam switching delays will also increase the impact of interference and noise on the perception results.
- the impact of the transmitter on the perceived signal mainly includes windowing, precoding, beamforming and other processing that is unknown to the receiver, resulting in the receiver being unable to obtain true channel information.
- Random phase in the time domain comes from the state change (such as opening, closing, changing from one state to another, etc.) of at least one of the transmitter antenna, RF module (including various devices connected to the RF channel), digital processing module, and clock module during the signal transmission and reception process. If the device has more than one transmitter, each transmitter may generate an independent random phase. The random phase is generally consistent within the bandwidth of the transmitted signal, but the random phase values generated at different times are different, showing a random distribution within a certain arc range.
- the carrier frequency of the sensing signal is configured as f c , but due to the non-ideal characteristics of the device, the carrier frequency of the signal actually sent at the transmitting end has an error ⁇ f T , and the local oscillator frequency used to receive the signal at the receiving end has an error ⁇ f R .
- the Doppler frequency shift caused by the relative motion between the sensing object and the transmitting end and/or the receiving end device of the sensing signal is f d .
- the baseband signal frequency obtained by the receiving end is ( ⁇ f T - ⁇ f R )+f d ; wherein ⁇ f T - ⁇ f R is the carrier frequency offset at both ends of the transmitting and receiving ends, recorded as f offset . Therefore, the frequency of the baseband signal obtained by the receiving end consists of two parts: Doppler f d and carrier frequency offset f offset , as shown in FIG3 below. For this purpose, a transmission processing method of the present application is proposed.
- the transmission processing method includes:
- Step 401 A first device receives a first signal from a second device, where the first signal includes a first partial signal and a second partial signal, where the first partial signal and the second partial signal are in the same frequency band, and a center frequency of the first partial signal is higher than a center frequency of the second partial signal;
- Step 402 The first device determines a first parameter according to the first signal
- the first parameter is used to compensate for the perception result, and the first parameter includes a carrier frequency offset.
- the first part of the signal can be understood as a high-frequency part of the signal
- the second part of the signal can be understood as a low-frequency part of the signal.
- the center frequency may also be referred to as a carrier center frequency.
- the carrier frequency deviation may be understood as a carrier frequency deviation of the second device relative to the first device.
- receiving the first signal can be understood as receiving an echo signal of the first signal reflected by the sensing object.
- the first device may be a base station or a terminal
- the second device may be a base station or a terminal.
- the sensing scenario may include the following sensing scenarios:
- Scenario 1 the first device is a base station and the second device is a terminal;
- Scenario 2 the first device is base station A, and the second device is base station B;
- Scenario 3 the first device is terminal 1, and the second device is terminal 2.
- the Doppler dispersion phenomenon can be used to separate the Doppler f d caused by the relative motion between the sensing object and the first signal transceiver device and the carrier frequency offset f offset caused by the non-ideal characteristics of the device, so that the Doppler f d of the sensing object can be accurately obtained.
- the first device may perform a first process on the received first signal to obtain the above-mentioned first parameter.
- the specific principle of the first process may be set according to actual needs and is not further limited here.
- the principle of the first process is exemplarily described below.
- the Doppler frequency shifts generated on the high-frequency signal and the low-frequency signal of the first signal are respectively:
- ⁇ f T and ⁇ f R are usually at least 5 to 6 orders of magnitude smaller than f H and f L. Since the high-frequency signal and the low-frequency signal of the first signal are limited to be within the same frequency band, the carrier frequency offset f offset superimposed on the high-frequency signal and the low-frequency signal of the first signal is the same. Therefore, the motion speed of the perceived object can be directly estimated.
- the exact meaning of the relative motion speed v of the sensing object relative to the first signal transceiver device is: the rate of change of the sum of the signal propagation path length from the first device to the sensing object and the signal propagation path length from the sensing object to the second device.
- the change in the signal propagation path length from the first device to the sensing object is ⁇ R 1
- the change in the signal propagation path length from the sensing object to the second device is ⁇ R 2 .
- the relative motion speed v of the sensing object relative to the transceiver of the first signal is ( ⁇ R 1 + ⁇ R 2 )/ ⁇ t.
- the perceived object detected in the echo signal baseband spectrum of the high-frequency signal of the first signal can be associated with the perceived object detected in the echo signal baseband spectrum of the low-frequency signal of the first signal (as shown in FIG. 5B ) through some algorithms, that is, they are considered to be the same perceived object.
- the perceived object 1 detected in the echo signal baseband spectrum of the high-frequency signal can be associated with the perceived object 1 detected in the echo signal baseband spectrum of the low-frequency signal.
- the perceived object detected in the echo signal baseband spectrum of the high-frequency signal and the perceived object detected in the echo signal baseband spectrum of the low-frequency signal are naturally the same perceived object.
- the frequencies detected in the baseband spectrum of the echo signal of the high-frequency part signal of the first signal and the frequencies detected in the baseband spectrum of the echo signal of the low-frequency part signal of the first signal are respectively:
- the frequency detected in the baseband spectrum of the echo signal of the high-frequency part signal fd ,H + foffset ;
- the frequency detected in the baseband spectrum of the echo signal of the low-frequency part signal f d,L +f offset ;
- the center frequency fH of the high-frequency signal and the center frequency fL of the low-frequency signal are known, so the estimated value of the motion speed of the perceived object can be directly calculated based on ⁇ fHL .
- the estimated value of the carrier frequency offset can be calculated by substituting the estimated value of the motion speed into f d,H +f offset or f d,L +f offset
- the following method can be used to first estimate the estimated value of the carrier frequency deviation:
- the Doppler spectrum F d,H of the high-frequency signal and the Doppler spectrum F d,L of the low-frequency signal also have the above-mentioned proportional relationship.
- the carrier frequency deviation estimation method is as follows:
- Step 1 Shift. Set a carrier frequency offset step value ⁇ f offset and shift the baseband spectrum F H (of the high frequency signal) to The Doppler spectrum F d,H of the high-frequency signal and the carrier frequency offset f offset ) and the baseband spectrum FL of the low-frequency signal (the sum of the Doppler spectrum F d,L of the low-frequency signal and the carrier frequency offset f offset ) are respectively subtracted or added with n ⁇ f offset to obtain the spectra F H ′ and FL ′. From the graph of the spectrum, it can be seen that the spectrum is shifted leftward or rightward along the frequency axis, as shown in FIG6A .
- Step 2 scaling.
