[0041] The following will be combined with the drawings in this application to clearly and completely describe the technical solutions in this application. Obviously, the described embodiments are only part of the embodiments of this application, not all of them. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0042] It should be noted that, in this application, words such as "exemplary" or "for example" are used to indicate examples, illustrations or descriptions. Any embodiment or design described as "exemplary" or "for example" in this application should not be interpreted as being more preferred or more advantageous than other embodiments or designs. Specifically, the use of words such as "exemplary" or "for example" is intended to present related concepts in a specific way.

[0043] In the following, the terms "first" and "second" are used for descriptive purposes only and are not to be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features.

[0044] In the description of this application, unless otherwise specified, " / " means "or", for example, A / B can mean A or B. "And / or" in this article is only a description of the association relationship of associated objects, indicating that there can be three relationships. For example, A and / or B can mean: A exists alone, A and B exist at the same time, and B exists alone. In addition, "at least one" means one or more, and "multiple" means two or more.

[0045] As mentioned in the background technology, at present, when 5G signals use OFDM waveforms for perception, there are the following difficulties: 1. Due to the CP length limit of OFDM signals, the maximum perception distance is limited when using OFDM waveforms for perception; for example, the CP length corresponding to the 120KHz subcarrier spacing of 5G high frequency only supports a maximum perception distance of 87.8m. 2. Communication perception in the self-transmitting and self-receiving mode of a single station has very high requirements for hardware isolation, and the engineering implementation is difficult.

[0046] In view of the above technical problems, the embodiment of the present application provides a signal sending method, the idea of ​​which is that: the transmitting end generates a synaesthesia integrated signal; the time domain resources of the synaesthesia integrated signal include: a first time domain resource, a second time domain resource and a third time domain resource in sequence; the transmitting end sends the synaesthesia integrated signal on the second time domain resource; accordingly, the receiving end receives the synaesthesia integrated signal sent by the transmitting end in the second time domain resource within a preset time window; based on the received synaesthesia integrated signal, the perception information or communication information is obtained. It can be seen that the transmitting end has a blank before and after sending the synaesthesia integrated signal. In this way, the embodiment of the present application can flexibly configure the length of the first time domain resource so that the waveform of the synaesthesia integrated signal is more suitable for traditional communication processing operations (for example, since the traditional OFDM waveform includes 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); by flexibly configuring the length of the third time domain resource, the farthest perception distance is increased (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 farther the perception distance). 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 division, avoiding the isolation requirement between the receiving end and the transmitting end. Furthermore, the receiving end obtains the perception information or communication information based on the received synaesthesia integrated signal, and can realize the communication function and the perception function at the same time, reduce the perception resource overhead, and improve the spectrum efficiency.

[0047] See also Figure 1 , is a schematic diagram of the architecture of a synaesthesia integration system provided in an embodiment of the present application. Figure 1 As shown, the synaesthesia integration system includes: a transmitting end 110, a communication receiving end 120 and a perception receiving end 130.

[0048] The transmitting end 110 is used to transmit the synaesthesia integration signal.

[0049] In some embodiments, the transmitting end 110 is used to modulate the communication information onto the synaesthesia integration signal according to the configuration requirements, and then send the synaesthesia integration signal.

[0050] Exemplarily, the transmitting end 110 may transmit the synaesthesia integration signal via a wireless air interface.

[0051] Exemplarily, the transmitting end 110 may be a base station or a terminal device, etc. For example, the terminal device may be a mobile phone, a tablet computer, a desktop, a laptop, 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 a virtual reality (VR) device, etc. The embodiment of the present application does not impose any special restrictions on the specific form of the terminal device.

[0052] The communication receiving end 120 is used to receive the synaesthesia integration signal and obtain communication information based on the synaesthesia integration signal.

[0053] In some embodiments, the communication receiving end 120 includes a communication processing device for performing communication processing on the received synaesthesia integration signal to obtain communication information.

[0054] 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.

[0055] Exemplarily, the communication receiving end 120 may receive the synaesthesia integration signal through a wireless air interface.

[0056] Exemplarily, the communication receiving end 120 may be a base station or a terminal device, etc.

[0057] The sensing receiving end 130 is used to receive the synaesthesia integrated signal after being scattered by the sensing target, and obtain the sensing information based on the synaesthesia integrated signal.

[0058] In some embodiments, the perception receiving end 130 includes a perception processing device for performing perception processing on the received synaesthesia integration signal to obtain perception information.

[0059] Exemplarily, the perception receiving terminal 130 may receive the synaesthesia integration signal through a wireless air interface.

[0060] Exemplarily, the sensing receiving end 130 may be a base station or a terminal device, etc.

[0061] It should be noted that the communication receiving terminal 120 and the perception receiving terminal 130 in the embodiment of the present application can be integrated on the same device; or, the communication receiving terminal 120 and the perception receiving terminal 130 can be deployed on different devices respectively.

[0062] It should be noted that the system architecture and application scenarios described in the embodiments of the present application are intended to more clearly illustrate the technical solutions of the embodiments of the present application, and do not constitute a limitation on the technical solutions provided in the embodiments of the present application. 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 in the embodiments of the present application are also applicable to similar technical problems.

[0063] The signal sending method provided in the embodiment of the present application is described in detail below.

[0064] like Figure 2 As shown, the signal sending method provided in the embodiment of the present application is applied to Figure 1 The transmitting end 110 shown in FIG. 1 may include the following steps:

[0065] S201, the transmitting end generates a synaesthesia integrated signal.

[0066] In some embodiments, the above-mentioned synaesthesia integrated signal may be a pulse signal. Exemplarily, the synaesthesia integrated signal may be 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.

[0067] In some embodiments, the time domain resources of the above-mentioned synaesthesia integrated signal occupy N OFDM symbols, wherein 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.

[0068] In some embodiments, the time domain resources of the synaesthesia integrated signal include the first time domain resources, the second time domain resources and the third time domain resources in sequence. It should be noted that the time domain resources of the above-mentioned synaesthesia integrated signal occupy N OFDM symbols, which means that the first time domain resources, the second time domain resources and the third time domain resources of the synaesthesia integrated signal occupy N OFDM symbols in total. Exemplarily, assuming that the time domain resources of the synaesthesia integrated 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.

[0069] In some embodiments, the transmitting end does not send the synaesthesia integration signal in the first time domain resource and the third time domain resource. The waveform of the synaesthesia integration signal is shown 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.

[0070] In some embodiments, in a scenario of self-transmitting and self-receiving single-station sensing, the first time domain resource can be used for beam switching and other operations, the second time domain resource can be used for sending synaesthesia integrated signals, and the third time domain resource can be used for receiving sensing echo signals. In this way, the transmitting and receiving ends of a single station are time-divided, effectively avoiding signal leakage from the transmitting end to the receiving end, and avoiding the isolation requirement of single-station sensing.

[0071] In some embodiments, the first time domain resource and the second time domain resource are both located in the first OFDM symbol among the N OFDM symbols.

[0072] In some embodiments, the above step S201 can be implemented as follows: the transmitting end generates a synaesthesia integration signal according to preset configuration parameters.

[0073] The preset configuration parameters include at least one of the following:

[0074] A first parameter, the first parameter is used to indicate the number of OFDM symbols occupied by the synaesthesia integration signal;

[0075] A second parameter, the second parameter is used to determine the length or subcarrier spacing of a second time domain resource of the synaesthesia integration signal;

[0076] The third parameter is used to determine the length of the first time domain resource.

[0077] 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.

[0078] As a possible implementation, the first parameter (ie, the number of OFDM symbols occupied by the synaesthesia integrated signal) may be determined according to a preset perception distance, wherein the perception distance is the distance between the transmitter and the perception target.

[0079] Exemplarily, the number of OFDM symbols occupied by the synaesthesia integrated signal and the perception distance can satisfy a monotonically increasing relationship. That is, the farther the perception distance, the more OFDM symbols the synaesthesia integrated 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 integrated signal. For example, when the synaesthesia integrated signal occupies one OFDM symbol, it is suitable for scenes where the perception target is close, such as indoor perception scenes, smart life perception scenes, etc.; when the synaesthesia integrated signal occupies multiple OFDM symbols, it is suitable for scenes where the perception target is far away, such as smart low-altitude scenes (drones, etc.), smart traffic scenes (pedestrians, vehicles, railway detection, etc.).

[0080] As a possible 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, 4. For example, assuming that the duration of an OFDM symbol is T symbol , then the effective duration of the synaesthesia integration signal is

[0081] 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. Exemplarily, the smaller the value of m (for example, when m is 0 or 1), the longer the length of the second time domain resource, so that the time left for perception 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, so that the time left for perception reception (for example, the third time domain resource) is longer, and the more suitable it is for long-range perception.

[0082] As a possible 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 and OFDM signal are consistent, then the effective subcarrier is equivalent to 2 m Comb points, every 2 m The subcarriers are orthogonal, and the remaining subcarriers are side lobes of the effective subcarriers. m Only one valid orthogonal subcarrier is taken from the subcarriers for equalization and decoding.

[0083] As a possible implementation, the value of the third parameter may be the length of the CP of the OFDM symbol; or, the value of the third parameter may be other values ​​set by the user according to actual usage. Thus, the length of the first time domain resource may be the length of the CP of the OFDM symbol; or, the first time domain resource may also be set to other values ​​according to actual usage.

[0084] Exemplarily, taking the value of the first time domain resource as the length of the CP of the 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):

[0085] T front +T back =(N-2 -m )×T symbol +NT cp Formula (1)

[0086] Among them, T front represents the first time domain resource, T back represents the third time domain resource, N is the first parameter, representing 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.

[0087] Among them, the duty cycle corresponding to the effective signal of synaesthesia integration satisfies the following formula (2):

[0088] 2 -m ×T symbol / [N(T cp +T symbol )]Formula (2)

[0089] In summary, a complete synaesthesia integrated signal can be expressed in the time domain as follows:

[0090]

[0091] Among them, s tx (k t ) represents the synaesthesia integration 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 It represents the effective subcarrier index in the frequency domain, Inverse Fast Fourier Transform (IFFT), and Fs represents the sampling frequency.

[0092] It can be seen that the characteristics of the synaesthesia integrated signal in the time domain are: in the first time domain resource T frontNo signal is transmitted (T front The value can be T cp ); In the second time domain resource 2 -m T symbol Transmit the synaesthesia integration signal on the third time domain resource T back No signal is transmitted.

[0093] For example, Figure 3 , which is a schematic diagram of a synaesthesia integrated signal in the time domain provided by an embodiment of the present application. It can be seen that when m=1, N=1, the number of OFDM symbols occupied by the synaesthesia integrated signal is 1, and the effective duration of the synaesthesia integrated signal is half of 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).

[0094] For example, Figure 4 As shown in FIG. 1 , a schematic diagram of a synaesthesia integrated signal in the frequency domain provided by an embodiment of the present application is shown. It can be seen that since the effective subcarrier interval set in the embodiment of the present application is 2 m ×Δf, then in the frequency domain, every 2 m There will be one effective subcarrier (i.e. orthogonal subcarrier) for each subcarrier. In this way, when the communication receiving end is performing communication processing, it can obtain the subcarrier sequence every 2 m A valid orthogonal subcarrier is selected from each subcarrier for equalization and decoding.

[0095] In some embodiments, the above method further includes: the transmitting end sends the preset configuration parameters to the receiving end; thus, the receiving end can configure and demodulate the synaesthesia integration signal according to the preset configuration parameters.

[0096] In some embodiments, the above step S201 can be implemented as the following steps:

[0097] Step a1: The sender obtains the communication information to be transmitted.

[0098] Step a2: The transmitting end modulates and encodes the communication information to obtain modulation symbols.

[0099] For example, the transmitter can modulate and encode the communication information by using quadrature phase shift keying (QPSK), quadrature amplitude modulation (QAM) containing 16 symbols, or 64QAM. Among them, 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; 64QAM requires 6 bits of binary signal to encode 64 different modulation symbols.

[0100] It is understandable that the transmitter can select different modulation modes according to different channel environments. For example, if the signal-to-noise ratio of the current channel environment is high, the 64QAM mode can be selected to increase the system throughput. If the noise power of the current channel environment is large, the QPSK mode can be selected to reduce the system throughput.

[0101] Step a3: The transmitting end performs resource mapping on the modulation symbols to obtain a frequency domain subcarrier sequence.

[0102] 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.

[0103] Layer mapping is to map the modulation symbol to different transport layers (new data streams). The transport layer is the transmission channel, and the number of transport layers indicates the number of transmission channels used simultaneously. For example, if the number of transport layers is 2, then two transmission channels transmit information simultaneously. At the same time, the information transmitted by two transport layers can be the same or different, which is not limited here.

[0104] Step a4: The transmitting end performs symbol shaping processing on the frequency domain subcarrier sequence to obtain a synaesthesia integrated signal.

[0105] Exemplarily, the symbol shaping process may be IFFT, so that the frequency domain subcarrier sequence may be transformed into the time domain to obtain a synaesthesia integrated signal in the time domain.

[0106] S202: The transmitting end transmits a synaesthesia integration signal on a second time domain resource.

[0107] It can be understood that the transmitter does not send any signal on the first time domain resource and the third time domain resource.

[0108] Exemplarily, the transmitting end may send the synaesthesia integration signal through a wireless air interface.

[0109] It can be understood that in the signal transmission method provided in the embodiment of the present application, the transmitting end generates a synaesthesia integrated signal; the time domain resources of the synaesthesia integrated signal include: a first time domain resource, a second time domain resource and a third time domain resource in sequence; the transmitting end transmits the synaesthesia integrated signal on the second time domain resource. It can be seen that the transmitting end has a blank space before and after sending the synaesthesia integrated signal. In this way, the embodiment of the present application 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 farthest perception distance.

[0110] The signal receiving method provided in the embodiment of the present application is described in detail below.

[0111] like Figure 5 As shown, the signal receiving method provided in the embodiment of the present application is applied to the receiving end (the receiving end may be as shown in Figure 1 The communication receiving end 120 or the perception receiving end 130 shown in FIG. 1 ), the method may include the following steps:

[0112] S301: A receiving end receives a synaesthesia integration signal sent by a sending end in a second time domain resource within a preset time window.

[0113] Exemplarily, in the case where the receiving end is a perception receiving end, the perception receiving end receives, within a preset time window, a synaesthesia integrated signal that is sent by the sending end within the second time domain resource and reflected by the perception target.

[0114] In some embodiments, the above method further includes: determining a preset time window according to preset configuration parameters.

[0115] As a possible 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 ).

[0116] For example, Figure 6 As shown, when the transmitting end sends the synaesthesia integrated signal in the form of m=1, N=2, the communication receiving end is as follows Figure 6 The synaesthesia integration signal is received within the preset time window shown. 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 symbolThe preset time window includes other time domain resources in the first OFDM symbol except the first time domain resource.

[0117] It is understandable that when T front The value of T cp When the communication receiving end changes from T front Start receiving T symbol The length of the integrated signal is equivalent to the CP removal operation of the traditional OFDM waveform.

[0118] As another possible implementation method, when the receiving end is a perceptual receiving end and the transceiver mode is a send-before-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 a third time domain resource.

[0119] For example, Figure 6 As shown in the figure, when the transmitter sends the synaesthesia integrated signal in the form of m=1, N=2, the receiver perceives Figure 6 The synaesthesia integration signal is received within the preset time window shown. 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 .

[0120] It is understandable that if the transmission and reception mode adopts the send-first-receive-later mode, the transmission and reception of the integrated synaesthesia signal are carried out in time-sharing, which can avoid the isolation requirements of the transmitter and the receiver, and can realize the perception function without basically changing the existing hardware. Of course, the send-first-receive-later mode may have a certain close-range perception blind spot.

[0121] As another possible implementation method, when the receiving end is a perception receiving end and the transmission and reception mode is a simultaneous transmission and reception 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.

[0122] For example, Figure 6 As shown in the figure, when the transmitter sends the synaesthesia integrated signal in the form of m=1, N=2, the receiver perceives Figure 6 The synaesthesia integration signal is received within the preset time window shown. The starting time of the preset time window can be T front , the preset time window length is: 2 -m ×T symbol +T back .

[0123] 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.

[0124] S302: The receiving end obtains perception information or communication information based on the received synaesthesia integration signal.

[0125] In some embodiments, the above 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.

[0126] 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.

[0127] The communication processing may adopt a conventional OFDM waveform processing method. Exemplarily, the communication receiving end performs communication processing on the received synaesthesia integrated signal to obtain communication information, which may be implemented as the following steps:

[0128] Step b1: The communication receiving end performs fast Fourier transformation (FFT) on the synaesthesia integrated signal to obtain frequency domain subcarrier information.

[0129] Step b2: The communication receiving end obtains the effective subcarrier from the frequency domain subcarrier information.

[0130] For example, the communication receiving end m subcarriers to obtain a valid subcarrier.

[0131] Step b3: The communication receiving end performs operations such as equalization and decoding on the effective subcarriers to obtain communication information.

[0132] It can be seen that the parameters of the synaesthesia integration signal provided in the embodiment of the present application (for example, the first time domain resource T front The value of T cp ) is well compatible with the existing communication OFDM waveform processing framework. 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.

[0133] 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.

[0134] Exemplarily, the above-mentioned perception information may include: information such as the distance, speed, azimuth and pitch angle of the perceived target.

[0135] Exemplarily, the perception function of the synaesthesia integrated signal can be applied to the scenario of detecting the position information of the perception target, the scenario of reconstructing the environment based on the detected position information of the perception target, and the scenario of detecting breathing and heartbeat.

[0136] It can be understood that the signal receiving method provided by the embodiment of the present application, the receiving end can receive the synaesthesia integrated signal sent by the transmitting end in the second time domain resource within the preset time window; based on the received synaesthesia integrated signal, the perception information or communication information is obtained. 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 receiving and sending 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 application can flexibly adjust the length of the preset time window (the preset time window may include the second time domain resource and the third time domain resource; or, the preset time window may 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 the communication function and the perception function, reduce the perception resource overhead, and improve the spectrum efficiency.

[0137] Exemplarily, the signal sending method and signal receiving method provided in the embodiments of the present application are described below from the perspectives of the sending end, the communication receiving end, and the perception receiving end, respectively.

[0138] like Figure 7 As shown, after acquiring the communication information, the transmitting end 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 transmitting end 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 Transmit the synaesthesia integration signal on the third time domain resource T back No signal is transmitted.

[0139] 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; then the communication receiving end transmits 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.

[0140] When the transceiver mode is the send-before-receive mode, the receiver senses the front +2 -m T symbolWhen the receiving and transmitting mode is the simultaneous receiving and transmitting mode, the receiving end senses the signal from T front The receiving end starts receiving the synaesthesia integration signal at the moment. The sensing receiving end senses and processes the received synaesthesia integration signal to obtain sensing information.

[0141] To facilitate understanding, the signal sending method and signal receiving method provided in the embodiments of the present application are described below using different application scenarios as examples.

[0142] Scenario 1: The scenario where the base station sends and receives messages by itself (the sending end is the base station, the sensing receiving end is the base station, and the communication receiving end is the terminal device).

[0143] For example, Figure 8 As shown, in scenario one, the base station is configured as a transmitter and sends a synaesthesia integrated signal; at the same time, the base station also serves as a perception receiving end to receive the synaesthesia integrated signal reflected back by the perception target, and processes the synaesthesia integrated signal to obtain perception information; the terminal device serves as a communication receiving end to receive the synaesthesia integrated signal sent by the base station, and processes the synaesthesia integrated signal to obtain communication information.

[0144] For example, Fig. 9 As shown, the signal sending method and signal receiving method provided in the embodiments of the present application can be implemented as the following steps:

[0145] Sc1. The base station generates a synaesthesia integrated signal according to preset configuration parameters and sends the synaesthesia integrated signal.

[0146] 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).

[0147] In some embodiments, the preset configuration parameters may also include the location of the time domain resources of the synaesthesia integration signal, the sequence generation method of the synaesthesia integration signal, etc.

[0148] For example, assuming N=2, m=1, Δf=120KHz, T front Set to T cp , then the schematic diagram of the synaesthesia integrated signal in the time domain can be as follows Figure 6 The form shown in the figure. Among them, the synaesthesia integrated signal carries communication information, and the location scheduling of the time domain resources of the synaesthesia integrated signal can reuse the scheduling signaling of the PDSCH.

[0149] For example, Figure 6As shown in the figure, 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 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 2 traditional OFDM waveforms (when the value of N is 2).

[0150] In some embodiments, the base station transmits T symbol After receiving the synaesthesia signal of / 2 effective length, the transmitting channel is switched to the receiving channel.

[0151] 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.

[0152] Sc3. The terminal device receives the synaesthesia integrated signal sent by the base station, and performs communication processing on the synaesthesia integrated signal to obtain communication information.

[0153] It can be understood that since the parameters of the synaesthesia integrated signal designed in the embodiment of the present application 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.

[0154] 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 in the time window corresponding to the first OFDM symbol.

[0155] Sc4. The base station receives the synaesthesia integrated signal (or perception echo signal) reflected by the perception target, and performs perception processing on the signal to obtain perception information.

[0156] It can be understood that the base station in scenario one is in a self-transmitting and self-receiving working mode. Therefore, in order to avoid the isolation requirement of a single base station in a self-transmitting and self-receiving scenario, the base station can adopt a sending-first-then-receiving working mode.

[0157] For example, the base station can cp +T symbol / 2, it starts receiving the sensing echo signal and, after sensing and processing according to the preset configuration parameters, obtains information such as the distance, speed, azimuth, and pitch angle of the sensed target.

[0158] 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).

[0159] For example, Fig.10 As shown, in scenario two, base station A is configured as a transmitter and sends a synaesthesia integrated signal; base station B, as a perception receiving end, receives the synaesthesia integrated signal reflected back by the perception target, and processes the synaesthesia integrated signal to obtain perception information; the terminal device, as a communication receiving end, receives the synaesthesia integrated signal sent by base station A, and processes the synaesthesia integrated signal to obtain communication information.

[0160] For example, Fig.11 As shown, the signal sending method and signal receiving method provided in the embodiments of the present application can be implemented as the following steps:

[0161] Sd1. Base station A generates a synaesthesia integrated signal according to preset configuration parameters and sends the synaesthesia integrated signal.

[0162] Exemplarily, the specific implementation of the above step d1 can refer to the above step c1, which will not be repeated here.

[0163] 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.

[0164] Sd3. The terminal device receives the synaesthesia integrated signal sent by the base station A, and performs communication processing on the synaesthesia integrated signal to obtain communication information.

[0165] Exemplarily, the specific implementation method of the above step d3 can refer to the above step c3, which will not be repeated here.

[0166] Sd4, 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.

[0167] It can be understood that in scenario 2, base station A sends an integrated interaceptive signal, and base station B receives a sensing echo signal, so there is no isolation problem, and base station B can adopt a simultaneous transmission and reception working mode.

[0168] For example, base station B can cp It starts receiving the sensing echo signal at all times, and after sensing and processing according to the preset configuration parameters, it obtains information such as the distance, speed, azimuth, and pitch angle of the sensing target.

[0169] Scenario three: The 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).

[0170] For example, Fig.12 As shown, in scenario three, the terminal device is configured as a transmitter and sends a synesthesia integrated signal; the perception receiving end of the base station receives the synesthesia integrated signal reflected back by the perception target, and processes the synesthesia integrated signal to obtain perception information; the communication receiving end of the base station receives the synesthesia integrated signal sent by the terminal device, and processes the synesthesia integrated signal to obtain communication information.

[0171] For example, Fig.13 As shown, the signal sending method and signal receiving method provided in the embodiments of the present application can be implemented as the following steps:

[0172] Se1. The base station sends preset configuration parameters to the terminal device.

[0173] Exemplarily, the base station may send preset configuration parameters to the terminal device via signaling.

[0174] Se2. The terminal device generates a synaesthesia integration signal according to preset configuration parameters and sends the synaesthesia integration signal.

[0175] For example, assuming N=1, m=1, Δf=120KHz, T front Set to T cp , then the schematic diagram of the synaesthesia integrated signal in the time domain can be as follows Fig.14 The form shown in the figure. Among them, the synaesthesia integrated signal carries communication information, and the location scheduling of the time domain resources of the synaesthesia integrated signal can reuse the scheduling signaling of the PDSCH.

[0176] For example, Fig.14 As shown in the figure, 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 has a space T in front 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.

[0177] Se3. The communication receiving end of the base station receives the synaesthesia integrated signal sent by the terminal device, and performs communication processing on the synaesthesia integrated signal to obtain communication information.

[0178] For example, Fig.14As shown, when N=1, each synaesthesia integration signal just occupies one OFDM symbol, so the base station can receive the synaesthesia integration signal according to the time window corresponding to the traditional OFDM symbol.

[0179] 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 senses and processes the signal to obtain sensing information.

[0180] In some embodiments, the perception receiving end of the base station can multiplex the communication receiving end to receive the synaesthesia integrated signal, perform perception processing on the synaesthesia integrated signal, obtain the parameter estimation result of the perceived target, and finally reconstruct the environment based on information such as the distance, azimuth, pitch angle and scattering intensity of different targets.

[0181] Scenario 4: The scenario where the terminal device sends and receives messages by itself (the sending end is the terminal device, the sensing receiving end is the terminal device, and the communication receiving end is the base station).

[0182] For example, Fig.15 As shown, in scenario four, the terminal device is configured as a transmitter 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.

[0183] For example, Fig.16 As shown, the signal sending method and signal receiving method provided in the embodiments of the present application can be implemented as the following steps:

[0184] Sf1. The terminal device requests the base station to send a synaesthesia integration signal and to obtain preset configuration parameters.

[0185] Sf2. In response to the request of the terminal device, the base station sends preset configuration parameters to the terminal device.

[0186] Exemplarily, the base station may send preset configuration parameters to the terminal device via signaling.

[0187] Sf3. The terminal device generates a synaesthesia integration signal according to preset configuration parameters, and a part of the antenna of the terminal device is used as a transmitting antenna to send the synaesthesia integration signal.

[0188] Exemplarily, the specific implementation method of the above step f3 can refer to the above step e2, which will not be repeated here.

[0189] Sf4. The base station receives the synaesthesia integration signal sent by the terminal device as a communication receiving end, and performs communication processing on the synaesthesia integration signal to obtain communication information.

[0190] Exemplarily, the specific implementation of the above step f4 can refer to the above step e3, which will not be repeated here.

[0191] 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 senses and processes the signal to obtain sensing information.

[0192] 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 receiving method to receive the echo signal, and after sensing and processing the echo signal according to preset configuration parameters, detect the fluctuations of the chest cavity, thereby obtaining breathing and heartbeat perception information, etc.
