Description

Technical Field

[0001] The present application relates to the field of wireless communication technology, and in particular to a signal processing method, apparatus, computer equipment, and storage medium. Background Art

[0002] At present, the frame structure of the telepathic integrated base station (i.e., telepathic base station) is based on the communication signal frame structure (for example, the NR (New Radio) TDD (Time Division Duplexing) base station adopts the DDDSU frame structure, where D represents the downlink communication signal frame or time slot, U represents the uplink communication signal frame or time slot, and S represents the special communication signal frame or time slot), and one or more communication signal frames are replaced with perception signal frames, such as Figure 1 As shown, for example, 1 D and 1 S are converted into 2 P frames, where P (Perceive) represents the perception signal frame).

[0003] At the same time, in order to eliminate the co-frequency interference of the perception signal frame of the integrated inter-sensory base station on the communication signal frames of the surrounding communication base stations, it is necessary to clear the communication signal frames in the same time domain as the perception signal frame in the signal frames of all surrounding communication base stations. In other words, the communication base station does not use the resources of the communication signal frame for communication to reduce the interference of the sensing signal corresponding to the perception signal frame on the communication signal. Although this method avoids the interference of the perception signal on the communication signal, it seriously reduces the communication performance and resource utilization of the communication base station due to the inability to use all the communication signal frames, and reduces the communication user experience.

[0048] In order to make the purpose, technical solutions and advantages of this application more clear, the following further describes this application in detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this application and are not intended to limit this application.

[0049] The signal processing method provided in the embodiment of the present application is mainly used for Figure 1 In the application environment shown in FIG. A terminal receives a mixed wireless signal sent by a base station device; the mixed wireless signal includes a perception signal and a communication signal. The terminal obtains a perception channel reference signal corresponding to the perception signal and a communication channel reference signal corresponding to the communication signal. Based on the perception channel reference signal and the communication channel reference signal, the terminal removes the perception signal from the mixed wireless signal to obtain a communication signal.

[0050] Base station equipment refers to the core equipment that constitutes the infrastructure of a mobile communication network. It is responsible for implementing wireless signal transmission between the mobile communication network and mobile terminal devices. Existing base station equipment not only has communication functions but also has perception functions. Therefore, the base station equipment of this application can be a communication base station equipment, a base station equipment that integrates communication and perception (i.e., a telepathic base station equipment), or a combination of a communication base station equipment and a telepathic base station equipment.

[0051] A terminal is a user-side device that receives and processes mixed wireless signals. It can be a smart terminal like a mobile phone or computer, or a smart wearable device like a smartwatch or smart bracelet.

[0052] In one embodiment, Figure 3 This is a flow chart of a signal processing method provided in accordance with an embodiment of the present application, wherein the method is applied to Figure 1 Taking the terminal in as an example, the method includes the following steps:

[0053] S301: Receive a mixed wireless signal sent by a base station device.

[0054] Among them, the mixed wireless signal includes a perception signal and a communication signal. A mixed wireless signal refers to a wireless signal that is a mixture of a perception signal and a communication signal. It should be noted that the mixed wireless signal can be sent by a communication base station device to a terminal. In this case, the communication base station receives the perception signal sent by the synaesthesia base station device, and the signal sent by the communication base station to the terminal carries the perception signal and the communication signal, forming a mixed wireless signal. The mixed wireless signal may also be that the terminal simultaneously receives the perception signal sent by the synaesthesia base station device and the communication signal sent by the communication base station device. The time domain and frequency domain of the perception signal and the communication signal are the same, forming a mixed wireless signal. The perception signal refers to the environmental perception signal. The communication signal refers to the signal used for network communication.

[0055] As an optional implementation of the embodiment of the present application, a communication base station device receives a perception signal sent by a synaesthesia base station device, forms a hybrid wireless signal based on the perception signal and the communication signal, and transmits the hybrid wireless signal to a terminal. The terminal receives the hybrid wireless signal sent by the communication base station device.

[0056] Another optional implementation of the embodiment of the present application is to receive a perception signal sent by a synaesthesia base station device and a communication signal sent by a communication base station device, wherein the time-frequency resources used by the synaesthesia base station device to send the perception signal and the communication signal to send the communication base station device are the same in both the time domain and the frequency domain.

[0057] S302: Acquire a sensing channel reference signal corresponding to the sensing signal and a communication channel reference signal corresponding to the communication signal.

[0058] The sensing channel reference signal refers to the sensing channel state information reference signal, namely the PCSI-RS (Phase-Tracking Channel State Information Reference Signal). The communication channel reference signal refers to the communication channel state information reference signal, namely the CCSI-RS (Common Channel State Information Reference Signal).

[0059] Optionally, in this embodiment, the perception channel reference signal is initiated by the synaesthesia base station device based on the perception time-frequency resources; and the communication channel reference signal is initiated by the communication base station device based on the communication time-frequency resources. The perception time-frequency resources refer to the time-frequency resources allocated by the synaesthesia base station device for transmitting perception information-related signals. The communication time-frequency resources refer to the time-frequency resources allocated by the communication base station device for transmitting communication information-related signals.

[0060] Optionally, in order to improve the accuracy of the acquired communication channel reference signal and the perception channel reference signal, interference between the two reference signals is avoided in this embodiment. Figure 4 As shown, the time domain of the sensing time-frequency resources is the same as that of the communication time-frequency resources; the frequency domain of the sensing time-frequency resources is different from that of the communication time-frequency resources. Figure 4 The horizontal axis represents the time domain, and the vertical axis represents the frequency domain. Figure 4 It can be seen that the time-frequency resources corresponding to the PCSI-RS and the CCSI-RS are the same in the time domain, and the time-frequency resources corresponding to the PCSI-RS and the CCSI-RS use the same Gold sequence, the same density and pattern, and cross in the frequency domain to avoid mutual interference between the two reference signals.

[0061] Optionally, in this embodiment, the terminal receives a sensing channel reference signal sent by the synaesthesia base station device based on sensing time-frequency resources, and a communication channel reference signal sent by the communication base station device based on communication time-frequency resources.

[0062] S303: Eliminate the perception signal in the mixed wireless signal based on the perception channel reference signal and the communication channel reference signal to obtain a communication signal.

[0063] As an optional implementation of the embodiment of the present application, the sensing channel reference signal and the communication channel reference signal are input into an intelligent processing tool, and the intelligent processing tool eliminates the sensing signal from the mixed wireless signal based on the sensing channel reference signal and the communication channel reference signal to obtain a communication signal. The intelligent processing tool can be a processing device that can intelligently identify and eliminate the sensing signal.

[0064] According to the above signal processing method, the terminal can receive a mixed wireless signal sent by the base station device; wherein the mixed wireless signal includes a perception signal and a communication signal. A perception channel reference signal corresponding to the perception signal and a communication channel reference signal corresponding to the communication signal are obtained. Based on the perception channel reference signal and the communication channel reference signal, the perception signal in the mixed wireless signal is eliminated to obtain a communication signal. Based on the method of the present application, the perception signal in the mixed wireless signal can be eliminated to obtain a communication signal. In other words, the communication base station can normally use the communication signal frame for communication. Although the perception signal in the perception signal frame will interfere with the communication signal of the communication signal frame, the method of the present application can obtain the communication signal from the mixed wireless signal without affecting the normal communication of the terminal, thereby effectively improving the communication performance and communication resource utilization of the communication base station and the communication base station.

[0065] In one embodiment, in order to accurately eliminate the perception signal, such as Figure 5 As shown, an optional implementation of S203 includes:

[0066] S501: Determine a perceptual channel matrix based on a perceptual channel reference signal.

[0067] Optionally, in this embodiment, a method such as LS (Least Squares) least squares method or LMMSE (Line Minimum Mean Square) is used to process the perception channel reference signal to obtain a perception channel matrix.

[0068] S502: Determine a communication channel matrix based on a communication channel reference signal.

[0069] Optionally, in this embodiment, a method such as LS least squares method or LMMSE is used to process the communication channel reference signal to obtain a communication channel matrix.

[0070] S503: Eliminate the perception signal in the mixed wireless signal based on the perception channel matrix and the communication channel matrix to obtain a communication signal.

[0071] Optionally, in this embodiment, the mixed wireless signal is demodulated to obtain a first signal vector. Based on the sensing channel matrix and the communication channel matrix, a second signal vector corresponding to the sensing signal in the first signal vector is eliminated to obtain a third signal vector corresponding to the communication signal. The communication signal is determined based on the third signal vector.

[0072] Optionally, in this embodiment, an optional implementation of determining the communication signal based on the third signal vector is to use the third signal vector as the communication signal, or to modulate the third signal vector to obtain the communication signal.

[0073] In this embodiment, a sensing channel matrix is ​​determined based on a sensing channel reference signal. A communication channel matrix is ​​determined based on a communication channel reference signal. Based on the sensing channel matrix and the communication channel matrix, the sensing signal is eliminated from the mixed wireless signal to obtain a communication signal, thereby improving the accuracy of the determined communication signal.

[0074] On the basis of the above embodiment, in order to further improve the accuracy of the communication signal, as Figure 6 As shown, in the above embodiment, based on the perception channel matrix and the communication channel matrix, an optional implementation method of eliminating the second signal vector corresponding to the perception signal in the first signal vector to obtain the third signal vector corresponding to the communication signal includes:

[0075] S601: Determine an elimination method according to the matrix type of the communication channel matrix.

[0076] The elimination method indicates a method for eliminating the perception signal.

[0077] Optionally, in this embodiment, if the communication channel matrix is ​​a reversible matrix, the elimination method is determined based on the inverse matrix of the communication channel matrix. If the communication channel matrix is ​​a generalized reversible matrix, the elimination method is determined based on the Moore-Penrose generalized inverse matrix of the communication channel matrix.

[0078] S602: Based on the elimination method, the perception channel matrix, and the communication channel matrix, a second signal vector corresponding to the perception signal in the first signal vector is eliminated to obtain a third signal vector corresponding to the communication signal.

[0079] As an optional implementation of the present application, if the communication channel matrix is ​​a reversible matrix, the second signal vector corresponding to the perception signal in the first signal vector can be eliminated based on the following formula (1) to obtain a third signal vector corresponding to the communication signal:

[0080] Xc = (H1^(-1) * Y) - (H1^(-1) * H2 * Xp) (1)

[0081] In formula (1), Xc represents the third signal vector; Y represents the first signal vector; Xp represents the signal vector of the perception signal; H1^(-1) represents the inverse matrix of the communication channel matrix; H1 represents the communication channel matrix; and H2 represents the perception channel matrix.

[0082] As another optional implementation of the present application, if the communication channel matrix is ​​a generalized reversible matrix, the second signal vector corresponding to the perception signal in the first signal vector can be eliminated based on the following formula (2) to obtain a third signal vector corresponding to the communication signal:

[0083] Xc = (H1^(+) * Y) - (H1^(+) * H2 * Xp) (2)

[0084] In formula (2), Xc represents the third signal vector; Y represents the first signal vector; Xp represents the signal vector of the perception signal; H1^(+) represents the Moore-Penrose generalized inverse matrix of the communication channel matrix; H1 represents the communication channel matrix; and H2 represents the perception channel matrix.

[0085] In this embodiment, a cancellation method is determined based on the matrix type of the communication channel matrix. Based on the cancellation method, as well as the sensing channel matrix and the communication channel matrix, the second signal vector corresponding to the sensing signal in the first signal vector is cancelled to obtain a third signal vector corresponding to the communication signal. This embodiment effectively improves the accuracy of the obtained third signal vector, thereby improving the accuracy of the obtained communication signal.

[0095] Based on the sensing channel reference signal and the communication channel reference signal, the sensing signal in the mixed wireless signal is eliminated to obtain a communication signal.

[0096] In this embodiment, the terminal can receive a mixed wireless signal sent by a base station device; wherein the mixed wireless signal includes a perception signal and a communication signal. A perception channel reference signal corresponding to the perception signal and a communication channel reference signal corresponding to the communication signal are obtained. Based on the perception channel reference signal and the communication channel reference signal, the perception signal in the mixed wireless signal is eliminated to obtain a communication signal. Based on the method of the present application, the perception signal in the mixed wireless signal can be eliminated to obtain a communication signal. In other words, the communication base station can normally use the communication signal frame for communication. Although the perception signal in the perception signal frame will interfere with the communication signal of the communication signal frame, the method of the present application can obtain the communication signal from the mixed wireless signal without affecting the normal communication of the terminal, thereby effectively improving the communication performance and communication resource utilization of the communication base station and the communication base station.
