[0032] The following will clearly and completely describe the technical solutions of this disclosure in conjunction with the accompanying drawings. Obviously, the embodiments described are only some of the embodiments of this disclosure, not all of them. All other embodiments derived by persons of ordinary skill in the art based on the embodiments of this disclosure without inventive effort are within the scope of protection of this disclosure.

[0033] It should be noted that, in this disclosure, words such as "exemplary" or "for example" are used to describe examples, illustrations, or explanations. Any embodiment or design described in this disclosure using "exemplary" or "for example" should not be interpreted as being more preferred or more advantageous than other embodiments or designs. Rather, the use of words such as "exemplary" or "for example" is intended to present the relevant concepts in a concrete manner.

[0034] In the following, the terms "first," "second," etc. are used for descriptive purposes only and should not be understood to indicate or imply relative importance or implicitly specify the quantity of the technical features indicated. Therefore, a feature specified as "first," "second," etc. may explicitly or implicitly include one or more of the features.

[0035] In the description of this disclosure, unless otherwise specified, " / " means "or." For example, A / B can mean A or B. "And / or" herein is merely a description of an association relationship between associated objects, indicating that three possible relationships exist. For example, "A and / or B" can mean: only A, only B, and both A and B. Furthermore, "at least one" means one or more, and "a plurality" means two or more.

[0036] Currently, there are two challenges when sensing fifth-generation mobile communication technology (5G) signals using orthogonal frequency division multiplexing (OFDM) waveforms: First, the maximum sensing distance when using OFDM waveforms is limited by the length of the cyclic prefix (CP) of OFDM signals. For example, the CP length corresponding to the 5G high-frequency 120KHz subcarrier spacing only supports a maximum sensing distance of 87.8m. Second, communication sensing in the self-transmitting and self-receiving mode of a single station places very high requirements on hardware isolation, making its implementation difficult.

[0037] To address the above technical issues, embodiments of the present disclosure provide a signal transmission method. The method comprises: a transmitting end generates a synaesthesia-integrated signal, wherein the time domain resources of the synaesthesia-integrated signal sequentially include: a first time domain resource, a second time domain resource, and a third time domain resource; the transmitting end transmits the synaesthesia-integrated signal on the second time domain resource. Accordingly, a receiving end receives the synaesthesia-integrated signal transmitted by the transmitting end in the second time domain resource within a preset time window; and based on the received synaesthesia-integrated signal, acquires perception information or communication information. As can be seen, the transmitting end includes a blank space before and after transmitting the synaesthesia-integrated signal. Thus, embodiments of the present disclosure can flexibly configure the length of the first time domain resource to make the waveform of the synaesthesia-integrated signal more suitable for traditional communication processing operations (for example, since traditional OFDM waveforms include a cyclic prefix, the length of the first time domain resource can be set to the length of the cyclic prefix of the OFDM symbol to be more suitable for traditional communication processing operations). Flexible configuration of the length of the third time domain resource can also improve the maximum perception distance (since the third time domain resource is used to receive the echo signal of the synaesthesia-integrated signal, the longer the length of the third time domain resource, the longer the perception distance). The receiver can receive the synaesthesia signal sent by the transmitter on the second time domain resource within a preset time window, enabling time-sharing of transmission and reception, thus avoiding the isolation requirement between the receiver and transmitter. Furthermore, the receiver can obtain perception or communication information based on the received synaesthesia signal, enabling simultaneous communication and perception functions, reducing perception resource overhead and improving spectrum efficiency.

[0038] 1 is a schematic diagram of the architecture of a synaesthesia integration system according to an embodiment of the present disclosure. As shown in FIG1 , the synaesthesia integration system includes: a transmitting terminal 110 , a communication receiving terminal 120 , and a perception receiving terminal 130 .

[0039] The transmitting end 110 is used to transmit the synaesthesia integration signal.

[0040] In some embodiments, the transmitting end 110 is configured to modulate the communication information onto the synaesthesia integration signal according to configuration requirements, and then transmit the synaesthesia integration signal.

[0041] Exemplarily, the transmitting end 110 may transmit the synaesthesia integration signal via a wireless air interface.

[0042] For example, the transmitting end 110 may be a base station or a terminal device. For example, the terminal device may be a mobile phone, a tablet computer, a desktop / laptop computer, a handheld computer, a notebook computer, an ultra-mobile personal computer (UMPC), a netbook, a cellular phone, a personal digital assistant (PDA), an augmented reality (AR) or virtual reality (VR) device, etc. The embodiments of the present disclosure do not impose any particular limitation on the form of the terminal device.

[0043] The communication receiving end 120 is used to receive the synaesthesia integration signal and obtain communication information based on the synaesthesia integration signal.

[0044] In some embodiments, the communication receiving end 120 includes a communication processing device, which is used to perform communication processing on the received synaesthesia integration signal to obtain communication information.

[0045] In some embodiments, the communication receiving end 120 includes a receiving antenna, and the communication receiving end 120 can receive the synaesthesia integration signal through the receiving antenna.

[0046] Exemplarily, the communication receiving end 120 may receive the synaesthesia integration signal through a wireless air interface.

[0047] Exemplarily, the communication receiving end 120 may be a base station or a terminal device, etc.

[0048] The perception receiving end 130 is used to receive the synaesthesia integrated signal scattered by the perception target and obtain perception information based on the synaesthesia integrated signal.

[0049] In some embodiments, the perception receiving end 130 includes a perception processing device, which is used to perform perception processing on the received synaesthesia integration signal to obtain perception information.

[0050] Exemplarily, the perception receiving terminal 130 may receive the synaesthesia integration signal through a wireless air interface.

[0051] Exemplarily, the sensing receiving end 130 may be a base station or a terminal device, etc.

[0052] It should be noted that the communication receiving end 120 and the perception receiving end 130 in the embodiment of the present disclosure can be integrated on the same device; or, the communication receiving end 120 and the perception receiving end 130 can be deployed on different devices respectively.

[0053] It should be noted that the system architecture and application scenarios described in the embodiments of the present disclosure are intended to more clearly illustrate the technical solutions of the embodiments of the present disclosure, and do not constitute a limitation on the technical solutions provided by the embodiments of the present disclosure. Ordinary technicians in this field can know that with the evolution of the system architecture and the emergence of new business scenarios, the technical solutions provided by the embodiments of the present disclosure are also applicable to similar technical problems.

[0054] The signal sending method provided by the embodiment of the present disclosure is introduced below.

[0055] As shown in FIG2 , the signal sending method provided by the embodiment of the present disclosure is applied to the transmitting end 110 shown in FIG1 , and the signal sending method may include the following S201 and S202 .

[0056] In S201 , the transmitting end generates a synaesthesia integration signal.

[0057] In some embodiments, the synaesthesia integrated signal may be a pulse signal, for example, a traditional radar signal, a linear frequency modulation signal, a phase-coded signal, a stepped frequency signal, or a stepped frequency linear frequency modulation signal.

[0058] In some embodiments, the time domain resources of the synaesthesia integrated signal occupy N OFDM symbols, where N is a positive integer. For example, N can be a positive integer greater than or equal to 1 and less than or equal to 14.

[0059] In some embodiments, the time domain resources of the synaesthesia integration signal include a first time domain resource, a second time domain resource, and a third time domain resource in sequence. It should be noted that the time domain resources of the above-mentioned synaesthesia integration signal occupying N OFDM symbols means that the first time domain resources, the second time domain resources, and the third time domain resources of the synaesthesia integration signal occupy a total of N OFDM symbols. Exemplarily, assuming that the time domain resources of the synaesthesia integration signal occupy 10 OFDM symbols, the first time domain resources and the second time domain resources can occupy the first OFDM symbol of the 10 OFDM symbols, and the third time domain resources can occupy the remaining 9 OFDM symbols in the 10 OFDM symbols.

[0060] In some embodiments, the transmitting end does not transmit the synaesthesia integration signal in the first time domain resource and the third time domain resource. The waveform of the synaesthesia integration signal is manifested as follows: the waveform of the synaesthesia integration signal in the first time domain resource and the waveform of the synaesthesia integration signal in the third time domain resource are both blank.

[0061] In some embodiments, in a single-station sensing scenario with self-transmission and self-reception, the first time domain resource can be used for operations such as beam switching, the second time domain resource can be used to transmit the integrated synaesthesia signal, and the third time domain resource can be used to receive the sensing echo signal. This allows the transmitter and receiver of a single station to operate in a time-sharing manner, effectively avoiding signal leakage from the transmitter to the receiver and circumventing the isolation requirements of single-station sensing.

[0062] In some embodiments, the first time domain resource and the second time domain resource are both located in the first OFDM symbol of the N OFDM symbols.

[0063] In some embodiments, the above S201 may be implemented as follows: the transmitting end generates a synaesthesia integrated signal according to preset configuration parameters.

[0064] The preset configuration parameters include at least one of the following: a first parameter, which is used to indicate the number of OFDM symbols occupied by the synaesthesia integration signal; a second parameter, which is used to determine the length or subcarrier spacing of the second time domain resource of the synaesthesia integration signal; and a third parameter, which is used to determine the length of the first time domain resource.

[0065] In some embodiments, the preset configuration parameters also need to include the location scheduling of the time domain resources of the synaesthesia integration signal (for example, the location scheduling of the time domain resources of the synaesthesia integration signal can reuse the scheduling signaling of the physical downlink shared channel (PDSCH)), and other necessary parameters required to generate the synaesthesia integration signal.

[0066] As an implementation method, the first parameter (ie, the number of OFDM symbols occupied by the synaesthesia integrated signal) can be determined according to a preset perception distance. The perception distance is the distance between the transmitter and the perception target.

[0067] Exemplarily, the number of OFDM symbols occupied by the synaesthesia integration signal and the perception distance can satisfy a monotonically increasing relationship. That is, the longer the perception distance, the more OFDM symbols the synaesthesia integration signal occupies. In this way, the user can adapt to different perception distances by reasonably configuring the number of OFDM symbols occupied by the synaesthesia integration signal. For example, when the synaesthesia integration signal occupies one OFDM symbol, it is suitable for scenarios where the perception target is relatively close, such as indoor perception scenarios, smart life perception scenarios, etc.; when the synaesthesia integration signal occupies multiple OFDM symbols, it is suitable for scenarios where the perception target is relatively far away, such as smart low-altitude scenarios (drones, etc.), smart traffic scenarios (pedestrians, vehicles, railway side detection, etc.), etc.

[0068] As an implementation method, the effective duration of the synaesthesia integrated signal (ie, the second time domain resource) is the duration of the OFDM symbol. times, m is the value of the second parameter, m is a positive integer, and the value of m can be 0, 1, 2, 3, or 4. For example, assuming that the duration of an OFDM symbol is T symbol , then the effective duration of the synaesthesia integration signal is

[0069] It is understandable that in actual use, the user can adjust the length of the second time domain resource by configuring the value of m. For example, the smaller the value of m (for example, when m is 0 or 1), the longer the length of the second time domain resource. In this way, the time left for perception and reception (for example, the third time domain resource) is shorter, and the more suitable it is for close-range perception. The larger the value of m (for example, when m is 2, 3, or 4), the shorter the length of the second time domain resource. In this way, the time left for perception and reception (for example, the third time domain resource) is longer, and the more suitable it is for long-range perception.

[0070] As an implementation method, the subcarrier spacing of the synaesthesia integrated signal is 2 times the subcarrier spacing of the OFDM symbol. m times, m is the value of the second parameter, and m is a positive integer. For example, assuming that the subcarrier spacing of the OFDM symbol is Δf, the subcarrier spacing of the synaesthesia integrated signal is 2 m ×Δf. In this way, when performing communication processing, if the receiving window is consistent with the OFDM signal, then the effective subcarrier is equivalent to 2 m Comb points, every 2 m The subcarriers are orthogonal, and the remaining subcarriers are the side lobes of the effective subcarriers. mOnly one effective orthogonal subcarrier is taken from each subcarrier for equalization and decoding.

[0071] As an implementation, the value of the third parameter may be the length of the CP of an OFDM symbol; alternatively, the value of the third parameter may be another value set by the user based on actual usage. Thus, the length of the first time domain resource may be the length of the CP of an OFDM symbol; alternatively, the first time domain resource may be set to another value based on actual usage.

[0072] For example, taking the value of the first time domain resource as the length of the CP of an OFDM symbol as an example, the values ​​of the first time domain resource and the third time domain resource may satisfy the following formula (1): front +T back =(N-2 -m )×T symbol +NT cp Formula (1)

[0073] Among them, T front represents the first time domain resource, T back represents the third time domain resource, N is the first parameter, which represents the number of OFDM symbols occupied by the synaesthesia integrated signal, m is the second parameter, T cp Indicates the length of the CP of an OFDM symbol.

[0074] The duty cycle corresponding to the effective signal of synaesthesia integration satisfies the following formula (2): -m ×T symbol / [N(T cp +T symbol )] Formula (2)

[0075] In summary, a complete synaesthesia integrated signal can be expressed in the time domain as follows:

[0076] Among them, s tx (k t ) represents the time domain synaesthesia integrated signal, k t Represents the time domain sampling index, s com (k f ) represents the frequency domain synaesthesia integration signal (or frequency domain synaesthesia integration sequence), k f Indicates the frequency domain effective subcarrier index, IFFT indicates the inverse fast Fourier transform (Inverse Fast Fourier Transform), Fs indicates the sampling frequency, N symbol Indicates the total number of OFDM symbols included in the time domain resources of the synaesthesia integration signal.

[0077] It can be seen that the characteristics of the synaesthesia integration signal in the time domain are: in the first time domain resource T front No signal is transmitted (T front The value can be T cp ); In the second time domain resource 2 -m T symbol Transmit synaesthesia integration signal on the third time domain resource T back No signal is transmitted.

[0078] For example, as shown in FIG3 , a schematic diagram of a synaesthesia integration signal in the time domain provided by an embodiment of the present disclosure is shown. It can be seen that when m=1 and N=1, the number of OFDM symbols occupied by the synaesthesia integration signal is 1, and the effective duration of the synaesthesia integration signal is half the duration of the OFDM symbol (i.e., T symbol / 2). When m=1 and N=2, the number of OFDM symbols occupied by the synaesthesia integration signal is 2, and the effective duration of the synaesthesia integration signal is half of the duration of the OFDM symbol (ie, T symbol / 2).

[0079] For example, as shown in FIG4, a schematic diagram of a synaesthesia integrated signal in the frequency domain provided by an embodiment of the present disclosure is shown. m ×Δf, then in the frequency domain, every 2 m There will be an effective subcarrier (i.e. orthogonal subcarrier) for each subcarrier. In this way, when the communication receiving end is processing the communication, it can obtain the subcarrier sequence every 2 m A valid orthogonal subcarrier is selected for equalization and decoding.

[0080] In some embodiments, the signal transmission method further includes: the transmitting end transmitting preset configuration parameters to the receiving end, so that the receiving end can configure and demodulate the synaesthesia integrated signal according to the preset configuration parameters.

[0081] In some embodiments, the above S201 can be implemented as the following a1 to a4.

[0082] In a1, the sender obtains the communication information to be transmitted.

[0083] In a2, the transmitter modulates and encodes the communication information to obtain modulation symbols.

[0084] For example, the transmitter can modulate and encode communication information using quadrature phase shift keying (QPSK), quadrature amplitude modulation (QAM) with 16 symbols, or 64QAM. QPSK requires 2 bits of data to encode 4 different modulation symbols; 16QAM requires 4 bits of binary signal to encode 16 different modulation symbols; and 64QAM requires 6 bits of binary signal to encode 64 different modulation symbols.

[0085] It is understood that the transmitter can select different modulation schemes based on different channel environments. For example, if the signal-to-noise ratio (SNR) of the current channel environment is high, 64QAM can be selected to increase system throughput. If the noise power of the current channel environment is high, QPSK can be selected to reduce system throughput.

[0086] In step a3, the transmitting end performs resource mapping on the modulation symbols to obtain a frequency domain subcarrier sequence.

[0087] Exemplarily, the resource mapping method may be layer mapping, that is, the transmitting end may perform layer mapping on the modulation symbols to obtain a frequency domain subcarrier sequence.

[0088] Layer mapping involves mapping modulation symbols to different transport layers (new data streams). A transport layer is a transmission channel, and the number of layers in a transport layer indicates the number of channels in use simultaneously. For example, if the number of layers is two, two channels transmit information simultaneously. The information transmitted by two transport layers at the same time can be the same or different, without any limitation here.

[0089] In step a4, the transmitting end performs symbol shaping processing on the frequency domain subcarrier sequence to obtain a synaesthesia integrated signal.

[0090] Exemplarily, the symbol shaping process may be IFFT, so that the frequency domain subcarrier sequence can be transformed into the time domain to obtain a time domain synaesthesia integrated signal.

[0091] In S202, the transmitting end transmits the synaesthesia integration signal on the second time domain resource.

[0092] It can be understood that the transmitting end does not send any signal on the first time domain resource and the third time domain resource.

[0093] Exemplarily, the transmitting end may send the synaesthesia integration signal through a wireless air interface.

[0094] It is understood that in the signal transmission method provided in the embodiments of the present disclosure, the transmitter generates a synaesthesia-integrated signal, and the time domain resources of the synaesthesia-integrated signal include, in sequence: a first time domain resource, a second time domain resource, and a third time domain resource; the transmitter transmits the synaesthesia-integrated signal on the second time domain resource. It can be seen that the transmitter includes a blank space before and after transmitting the synaesthesia-integrated signal. As such, the embodiments of the present disclosure can flexibly configure the length of the first time domain resource to make the waveform of the synaesthesia-integrated signal more suitable for traditional communication processing operations; and flexibly configure the length of the third time domain resource to increase the maximum perception distance.

[0095] The signal receiving method provided by the embodiment of the present disclosure is introduced below.

[0096] As shown in Figure 5, the signal receiving method provided by the embodiment of the present disclosure is applied to the receiving end (the receiving end may be the communication receiving end 120 or the perception receiving end 130 as shown in Figure 1), and the signal receiving method may include the following S301 and S302.

[0097] In S301, a receiving end receives a synaesthesia integration signal sent by a transmitting end in a second time domain resource within a preset time window.

[0098] Exemplarily, when the receiving end is a perception receiving end, the perception receiving end receives, within a preset time window, a synaesthesia integration signal that is sent by the transmitting end in the second time domain resource and reflected by the perception target.

[0099] In some embodiments, the signal receiving method further includes: determining a preset time window according to preset configuration parameters.

[0100] As an implementation, when the receiving end is a communication receiving end, the starting time of the preset time window is the time when the communication receiving end receives the synaesthesia integration signal, or the time before the communication receiving end receives the synaesthesia integration signal. When the length of the first time domain resource is the length of the cyclic prefix, the preset time window may include other time domain resources in the first OFDM symbol except the first time domain resource (that is, the length of the preset time window is T symbol ).

[0101] For example, as shown in FIG6 , when the transmitting end sends the synaesthesia integration signal in the form of m=1, N=2, the communication receiving end receives the synaesthesia integration signal within the preset time window shown in FIG6 . The starting time of the preset time window is T front (T front The value can be T cp ) moment, the length of the preset time window is T symbol , the preset time window includes other time domain resources in the first OFDM symbol except the first time domain resource.

[0102] It is understandable that when T front The value of T cp When the communication receiving end is T front Start receiving T symbol The length of the synaesthesia integrated signal is equivalent to the CP removal operation of the traditional OFDM waveform.

[0103] As another implementation method, when the receiving end is a perception receiving end and the transceiver mode is a send-first-receive mode, the starting time of the preset time window is the end time of the second time domain resource, and the preset time window includes the third time domain resource.

[0104] For example, as shown in FIG6 , when the transmitting end sends the synaesthesia integration signal in the form of m=1, N=2, the sensing receiving end receives the synaesthesia integration signal within the preset time window shown in FIG6 . The starting time of the preset time window can be T front +2 -m ×T symbol , the length of the preset time window is T back .

[0105] It's understandable that if the transmit-before-receive mode is used, the transmission and reception of the integrated interawareness signal are time-sharing, which can circumvent the isolation requirements between the transmitter and receiver, and achieve the perception function without changing the relevant hardware. Of course, the transmit-before-receive mode may have certain close-range perception blind spots.

[0106] As another implementation method, when the receiving end is a perception receiving end and the transceiver mode is a simultaneous transceiver mode, the starting time of the preset time window is the end time of the first time domain resource, and the preset time window includes the second time domain resource and the third time domain resource.

[0107] For example, as shown in FIG6 , when the transmitting end sends the synaesthesia integration signal in the form of m=1, N=2, the sensing receiving end receives the synaesthesia integration signal within the preset time window shown in FIG6 . The starting time of the preset time window can be T front , the preset time window length is 2 -m ×T symbol +T back .

[0108] It is understandable that if the transmission and reception mode adopts the simultaneous transmission and reception mode, there will be no close-range blind spots, but the receiving end and the transmitting end need to have a high degree of isolation, and the support of multi-station or single-station full-duplex technology is required.

[0109] In S302, the receiving end obtains perception information or communication information based on the received synaesthesia integration signal.

[0110] In some embodiments, the above-mentioned signal receiving method further includes: the receiving end receives preset configuration parameters sent by the transmitting end, demodulates the synaesthesia integration signal according to the preset configuration parameters, and obtains perception information or communication information.

[0111] In some embodiments, when the receiving end is a communication receiving end, the communication receiving end performs communication processing on the received synaesthesia integration signal to obtain communication information.

[0112] The communication processing can adopt a traditional OFDM waveform processing method. Exemplarily, the communication receiving end performs communication processing on the received synaesthesia integrated signal to obtain communication information, which can be implemented as follows b1 to b3.

[0113] In b1, the communication receiving end performs fast Fourier transformation (FFT) on the synaesthesia integration signal to obtain frequency domain subcarrier information.

[0114] In b2, the communication receiving end obtains the effective subcarrier from the frequency domain subcarrier information.

[0115] For example, the communication receiving end m subcarriers to obtain a valid subcarrier.

[0116] In b3, the communication receiving end performs operations such as equalization and decoding on the effective subcarriers to obtain communication information.

[0117] It can be seen that the parameters of the synaesthesia integration signal provided by the embodiment of the present disclosure (for example, the first time domain resource T front The value of T cp ) is well compatible with the processing framework of related communication OFDM waveforms. Therefore, the synaesthesia integrated signal can be processed according to the traditional OFDM waveform processing method (for example, CP removal, FFT operation, etc.) to obtain communication information.

[0118] In some embodiments, when the receiving end is a perception receiving end, the perception receiving end performs perception processing on the received synaesthesia integration signal to obtain perception information.

[0119] For example, the above-mentioned perception information may include: information such as the distance, speed, azimuth, and pitch angle of the perceived target.

[0120] Exemplarily, the perception function of the synaesthesia integrated signal can be applied to scenarios of detecting the location information of the perception target, reconstructing the environment based on the detected location information of the perception target, and detecting breathing and heartbeat.

[0121] It can be understood that the signal receiving method provided by the embodiment of the present disclosure is that the receiving end can receive the synaesthesia integrated signal sent by the transmitting end in the second time domain resource within a preset time window; and obtain perception information or communication information based on the received synaesthesia integrated signal. It can be seen that the receiving end can receive the synaesthesia integrated signal sent by the transmitting end on the second time domain resource within the preset time window, so that the transmission and reception are carried out in time-sharing, avoiding the isolation requirement between the receiving end and the transmitting end. In addition, the embodiment of the present disclosure can flexibly adjust the length of the preset time window (the preset time window can include the second time domain resource and the third time domain resource; or, the preset time window can include the third time domain resource) to flexibly adjust the farthest perception distance. The receiving end obtains perception information or communication information based on the received synaesthesia integrated signal, and can simultaneously realize communication function and perception function, reduce perception resource overhead, and improve spectrum efficiency.

[0122] Exemplarily, the signal sending method and signal receiving method provided by the embodiments of the present disclosure are described below from the perspectives of the sending end, the communication receiving end, and the perception receiving end, respectively.

[0123] As shown in FIG7 , after acquiring the communication information, the transmitter modulates the communication information onto the subcarrier, and then transforms it into the time domain through IFFT to obtain the time domain synaesthesia integrated signal. When the transmitter sends the synaesthesia integrated signal, in the first time domain resource T front No signal is transmitted on the second time domain resource 2 -m T symbol Transmitting synaesthesia integrated signal, in the third time domain resource T back No signal is transmitted.

[0124] The communication receiving end is in the preset time window (the starting time of the preset time window is T front ; The length of the preset time window is T symbol ) receives the synaesthesia integration signal, and transforms the received synaesthesia integration signal into the frequency domain through FFT; and then the communication receiving end receives the synaesthesia integration signal every 2 m A valid subcarrier is obtained from each subcarrier, and operations such as equalization and decoding are performed on the valid subcarrier to obtain communication information.

[0125] When the receiving and sending mode is the send-first-receive mode, the receiving end senses the time from T front +2 -m T symbol Start receiving the synaesthesia integration signal at the moment; when the receiving and transmitting mode is the simultaneous receiving and transmitting mode, the sensing receiving end starts from T front The receiving end starts receiving the synaesthesia integration signal at the moment. The receiving end processes the received synaesthesia integration signal to obtain the perception information.

[0126] For ease of understanding, the signal sending method and signal receiving method provided by the embodiments of the present disclosure are described below using different application scenarios as examples.

[0127] Scenario 1: Base station self-transmitting and self-receiving scenario (the transmitting end is the base station, the sensing receiving end is the base station, and the communication receiving end is the terminal device)

[0128] For example, as shown in Figure 8, in scenario one, the base station is configured as a transmitting end and sends a synesthesia integrated signal. At the same time, the base station also serves as a perception receiving end to receive the synesthesia integrated signal reflected back by the perception target, and processes the synesthesia integrated signal to obtain perception information; the terminal device serves as a communication receiving end to receive the synesthesia integrated signal sent by the base station, and processes the synesthesia integrated signal to obtain communication information.

[0129] Exemplarily, as shown in FIG9 , the signal sending method and the signal receiving method provided by the embodiment of the present disclosure may be implemented as the following Sc1 to Sc4.

[0130] In Sc1, the base station generates a synaesthesia integration signal according to preset configuration parameters and sends the synaesthesia integration signal.

[0131] The preset configuration parameters include: a first parameter N (used to characterize the number of OFDM symbols occupied by the synaesthesia integration signal), a second parameter m (used to determine the length of the second time domain resource or subcarrier spacing of the synaesthesia integration signal) and a third parameter T front (used to determine the length of the first time domain resource).

[0132] In some embodiments, the preset configuration parameters may further include the location of the time domain resources of the synaesthesia integration signal, the sequence generation method of the synaesthesia integration signal, etc.

[0133] For example, assuming N=2, m=1, Δf=120KHz, T front Set to T cp , then the schematic diagram of the synaesthesia integration signal in the time domain may be in the form shown in Figure 6. The synaesthesia integration signal carries communication information, and the location scheduling of the time domain resources of the synaesthesia integration signal may reuse the scheduling signaling of the PDSCH.

[0134] For example, as shown in FIG6 , the synaesthesia integrated signal generated by the base station according to the preset configuration parameters is different from the traditional OFDM waveform in that: the synaesthesia integrated signal has a space T in front. cp The length does not transmit signals, the waveform length of the synaesthesia integrated signal is only 1 / 2 of the length of the traditional OFDM waveform (when the value of m is 1), and the waveform of one synaesthesia integrated signal occupies 2 traditional OFDM waveforms (when the value of N is 2).

[0135] In some embodiments, after the base station transmits T symbol After receiving the synaesthesia signal of / 2 effective length, the transmitting channel is switched to the receiving channel.

[0136] In Sc2, the base station sends the preset configuration parameters to the terminal device, so that the terminal device can demodulate the synaesthesia signal according to the preset configuration parameters.

[0137] In Sc3, the terminal device receives the synaesthesia integration signal sent by the base station, and performs communication processing on the synaesthesia integration signal to obtain communication information.

[0138] It can be understood that since the parameters of the synaesthesia integrated signal designed in the embodiment of the present disclosure are compatible with the traditional OFDM waveform processing framework, the terminal device can perform communication processing on the synaesthesia integrated signal according to the traditional OFDM waveform processing method to obtain communication information.

[0139] It should be noted that although each synaesthesia integrated signal can occupy N OFDM symbols, the effective duration of each synaesthesia integrated signal is 1 / 2 of the duration of one OFDM symbol. m times (that is, the effective duration of the synaesthesia integrated signal is less than or equal to the duration of one OFDM symbol), so the terminal device only needs to receive and process the signal of the time window corresponding to the first OFDM symbol.

[0140] In Sc4, the base station receives the synaesthesia integrated signal (or called the perception echo signal) reflected by the perception target, and performs perception processing on the signal to obtain perception information.

[0141] It can be understood that the base station in scenario 1 is in a self-transmitting and self-receiving working mode. Therefore, in order to circumvent the isolation requirements of a single base station in the self-transmitting and self-receiving scenario, the base station can adopt a sending-first-then-receiving working mode.

[0142] For example, the base station can cp +T symbol At time / 2, it starts receiving the perception echo signal and processes it according to the preset configuration parameters to obtain information such as the distance, speed, azimuth, and pitch angle of the perceived target.

[0143] Scenario 2: Base station A sends and base station B receives (the sending end is base station A, the sensing receiving end is base station B, and the communication receiving end is the terminal device)

[0144] For example, as shown in Figure 10, in scenario two, base station A is configured as a transmitting end and sends a synesthesia integrated signal; base station B is configured as a perception receiving end to receive the synesthesia integrated signal reflected back by the perception target, and processes the synesthesia integrated signal to obtain perception information; the terminal device is configured as a communication receiving end to receive the synesthesia integrated signal sent by base station A, and processes the synesthesia integrated signal to obtain communication information.

[0145] Exemplarily, as shown in FIG11 , the signal sending method and the signal receiving method provided by the embodiment of the present disclosure may be implemented as the following Sd1 to Sd4 .

[0146] In Sd1 , base station A generates a synaesthesia integration signal according to preset configuration parameters and sends the synaesthesia integration signal.

[0147] For example, the implementation of the above Sd1 can refer to the above Sc1, which will not be repeated here.

[0148] In Sd2, base station A sends preset configuration parameters to the terminal device and base station B, so that the terminal device and base station B can demodulate the synaesthesia signal according to the preset configuration parameters.

[0149] In Sd3, the terminal device receives the synaesthesia integration signal sent by the base station A, and performs communication processing on the synaesthesia integration signal to obtain communication information.

[0150] For example, the implementation of the above Sd3 can refer to the above Sc3, which will not be repeated here.

[0151] In Sd4, the base station B receives the synaesthesia integrated signal (or called the perception echo signal) reflected by the perception target, and performs perception processing on the signal to obtain perception information.

[0152] It can be understood that in scenario 2, base station A sends an integrated interaceptive signal, and base station B receives a perception echo signal, so there is no isolation problem, and base station B can adopt a simultaneous transmitting and receiving working mode.

[0153] For example, base station B can cp It starts receiving the sensing echo signal at all times and processes it according to the preset configuration parameters to obtain information such as the distance, speed, azimuth, and pitch angle of the sensing target.

[0154] Scenario 3: Scenario where the terminal device sends and the base station receives (the sending end is the terminal device, the sensing receiving end is the base station, and the communication receiving end is the base station)

[0155] For example, as shown in FIG12 , in scenario three, the terminal device is configured as a transmitter and sends a synesthesia integration signal; the perception receiving end of the base station receives the synesthesia integration signal reflected back by the perception target, and processes the synesthesia integration signal to obtain perception information; the communication receiving end of the base station receives the synesthesia integration signal sent by the terminal device, and processes the synesthesia integration signal to obtain communication information.

[0156] Exemplarily, as shown in FIG13 , the signal sending method and the signal receiving method provided by the embodiment of the present disclosure may be implemented as the following Se1 to Se4.

[0157] In Se1, the base station sends preset configuration parameters to the terminal device.

[0158] Exemplarily, the base station may send preset configuration parameters to the terminal device via signaling.

[0159] In Se2, the terminal device generates a synaesthesia integration signal according to preset configuration parameters and sends the synaesthesia integration signal.

[0160] For example, assuming N=1, m=1, Δf=120KHz, T front Set to T cp , then the schematic diagram of the synaesthesia integration signal in the time domain may be in the form shown in Figure 14. The synaesthesia integration signal carries communication information, and the location scheduling of the time domain resources of the synaesthesia integration signal may reuse the scheduling signaling of the PDSCH.

[0161] For example, as shown in FIG14 , the synaesthesia integrated signal generated by the terminal device according to the preset configuration parameters is different from the traditional OFDM waveform in that: the synaesthesia integrated signal is preceded by a space T cp The length does not transmit a signal, the waveform length of the synaesthesia integrated signal is only 1 / 2 of the length of the traditional OFDM waveform (when the value of m is 1), and the waveform of one synaesthesia integrated signal occupies one traditional OFDM waveform (when the value of N is 1). The terminal device configures the parameters according to the preset parameters and controls the transmitter not to transmit any valid signal after the first OFDM symbol.

[0162] In Se3, the communication receiving end of the base station receives the synaesthesia integration signal sent by the terminal device, and performs communication processing on the synaesthesia integration signal to obtain communication information.

[0163] For example, as shown in FIG14 , when N=1, each synaesthesia integrated signal occupies exactly one OFDM symbol. Therefore, the base station can receive the synaesthesia integrated signal according to the time window corresponding to the traditional OFDM symbol.

[0164] In Se4, the sensing receiving end of the base station receives the synaesthesia integrated signal (or echo signal) reflected by the sensing target or background, and performs sensing processing on the signal to obtain sensing information.

[0165] In some embodiments, the perception receiving end of the base station can reuse the synaesthesia integrated signal received by the communication receiving end, perform perception processing on the synaesthesia integrated signal, obtain the parameter estimation result of the perception target, and finally reconstruct the environment based on information such as the distance, azimuth, pitch angle and scattering intensity of different targets.

[0166] Scenario 4: Scenario where the terminal device sends and receives data independently (the sending end is the terminal device, the sensing receiving end is the terminal device, and the communication receiving end is the base station)

[0167] For example, as shown in FIG15 , in scenario four, the terminal device is configured as a transmitting end and sends a synesthesia integration signal. At the same time, the terminal device also serves as a perception receiving end to receive the synesthesia integration signal reflected back by the perception target, and processes the synesthesia integration signal to obtain perception information; the base station serves as a communication receiving end to receive the synesthesia integration signal sent by the terminal device, and processes the synesthesia integration signal to obtain communication information.

[0168] Exemplarily, as shown in FIG16 , the signal sending method and the signal receiving method provided by the embodiment of the present disclosure may be implemented as the following Sf1 to Sf5.

[0169] In Sf1, the terminal device requests the base station to send a synaesthesia integration signal and to obtain preset configuration parameters.

[0170] In Sf2, in response to the request of the terminal device, the base station sends preset configuration parameters to the terminal device.

[0171] Exemplarily, the base station may send preset configuration parameters to the terminal device via signaling.

[0172] In Sf3, the terminal device generates a synaesthesia integration signal according to preset configuration parameters, and a part of the antennas of the terminal device is used as a transmitting antenna to send the synaesthesia integration signal.

[0173] For example, the implementation of the above Sf3 can refer to the above Se2, which will not be repeated here.

[0174] In Sf4, the base station serves as a communication receiving end to receive the synaesthesia integration signal sent by the terminal device, and performs communication processing on the synaesthesia integration signal to obtain communication information.

[0175] For example, the implementation of the above Sf4 can refer to the above Se3, which will not be repeated here.

[0176] In Sf5, another antenna of the terminal device serves as a receiving antenna to receive the synaesthesia integrated signal (or echo signal) reflected by the sensing target, and performs sensing processing on the signal to obtain sensing information.

[0177] For example, when N=1, which is suitable for close-range perception scenarios, the receiving antenna of the terminal device can reuse the traditional OFDM signal reception method to receive the echo signal. After sensing and processing the echo signal according to preset configuration parameters, it detects the fluctuations of the chest cavity, thereby obtaining breathing and heartbeat perception information, etc.
