[0002] In the deployment of sensing-integrated base stations, the sensing bandwidth is limited. In order to prevent co-frequency interference, adjacent base stations need to be frequency-divided to avoid interference. However, the more frequency bands are divided, the smaller the sensing bandwidth of a single base station, which will also cause the sensing capability of a single base station to decrease. In order to ensure the transmission quality of sensing signals, it is necessary to accurately evaluate the interference suffered by the system and implement scientific frequency band planning and base station deployment strategies accordingly.

[0003] In the traditional method, the signal transmission process is simulated by establishing a base station network model to count the interference level. However, this simulation method requires a large amount of computing resources and time. In addition, since sensing-integrated base stations have not yet been deployed on a large scale for commercial use, and the number of existing test base stations is limited, it is difficult to construct a real network environment, which reduces the accuracy of actual network interference evaluation.

[0037] In order to make the purposes, technical solutions and advantages of the present application clearer, the present application will be further described in detail below with reference to the drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and not to limit the present application.

The terminal 102 can be, but is not limited to, various personal computers, notebook computers, smart phones, tablet computers, unmanned aerial vehicles, low-altitude flying vehicles, Internet of Things devices and portable wearable devices. The Internet of Things device can be a smart speaker, a smart television, a smart air conditioner, a smart vehicle-mounted device, a projection device, etc. The portable wearable device can be a smart watch, a smart bracelet, a head-mounted device, etc. The head-mounted device can be a virtual reality (VR) device, an augmented reality (AR) device, smart glasses, etc. The server 104 can be a standalone physical server, a server cluster or a distributed system composed of multiple physical servers, or a cloud server providing cloud computing services.

[0039] In an exemplary embodiment, as shown in Figure 2 , a co-channel interference evaluation method is provided. Taking the terminal 102 in Figure 1 as an example, the method includes the following steps 202 to 206. Wherein:

[0040] S202: In the case where the sensing target is determined to exist, a set of available frequency bands is acquired; the set of available frequency bands is used to represent a frequency band division strategy, and each element in the set of available frequency bands represents a number of frequency band divisions obtained according to a corresponding frequency band division strategy.

[0041] Optionally, the integrated sensing and communication base station implements detection, positioning, identification, imaging and other sensing functions on the target by using wireless signals. On the one hand, the communication system can use the same frequency spectrum or even multiplex hardware or signal processing modules to complete different types of sensing services. On the other hand, the sensing results can be used to assist communication access or management, thereby improving service quality and communication efficiency. In the deployment of the integrated sensing and communication base station, the sensing total bandwidth is limited, and in order to prevent co-frequency interference, adjacent base stations need to be frequency-divided to avoid interference. However, the more the divided frequency bands are, the smaller the sensing bandwidth of a single base station is, which will also cause the sensing capability of a single station to decrease. In order to ensure the transmission quality of the sensing signal, it is necessary to accurately evaluate the interference suffered by the communication system.

[0042] The sensing target refers to an object that needs to be detected by the integrated sensing and communication base station. When the sensing target exists, subsequent signal demodulation is performed, and a ranging and speed measurement process is executed, thereby avoiding waste of computing resources. The set of available frequency bands refers to an abstract representation of a set of frequency band division strategies, and each element represents division of total frequency band resources into N independent sub-frequency bands.

[0043] S204: A first number of first-order co-frequency neighbor zones and a second number of second-order co-frequency neighbor zones corresponding to each frequency band division strategy are acquired.

[0044] The first-order co-frequency neighbor zone refers to a base station that is directly adjacent to the current base station and uses the same frequency band, and the interference thereof is referred to as first-order interference. The second-order co-frequency neighbor zone refers to a base station that is spaced apart from the current base station by one base station and uses the same frequency band, and the interference thereof is referred to as second-order interference. The first number and the second number respectively represent the number of first-order and second-order co-frequency neighbor zones under a certain frequency band division strategy.

[0045] S206: According to the distance between the integrated sensing and communication base stations, the first number and the second number, a first-order interference uplift and a second-order interference uplift corresponding to each element in the set of available frequency bands are acquired.

[0046] Optionally, the distance between base stations refers to the physical distance between the integrated sensing and communication base stations, which affects the degree of signal attenuation. The first number and the second number represent the number of co-frequency neighbor zones, and the more the number is, the greater the superimposed interference is. By using the distance, the first number and the second number, a first-order interference uplift and a second-order interference uplift corresponding to each element in the set of available frequency bands are acquired.

[0047] S208: According to the first-order interference uplift and the second-order interference uplift, a total interference uplift corresponding to each element in the set of available frequency bands is acquired.

[0048] Optionally, the first order and second order interferences are integrated to obtain a total interference level of each frequency band division strategy, and the lower the total interference lift is, the smaller the impact of the frequency band division strategy on the performance of the communication system is.

[0049] In the above same frequency interference evaluation method, by determining the existence of the sensing target, the available frequency band set is obtained, the first number of the first order same frequency neighbor area and the second number of the second order same frequency neighbor area corresponding to each frequency band division strategy are obtained, the first order interference lift and the second order interference lift corresponding to each element in the available frequency band set are obtained according to the spacing of the integrated sensing base station, the first number and the second number, and the total interference lift corresponding to each element in the available frequency band set is obtained according to the first order interference lift and the second order interference lift. The relative interference lift between different frequency band division strategies can be quickly obtained, so that the optimal frequency band division strategy can be quickly determined, and the time cost and computing resources can be saved.

[0050] In an exemplary embodiment, the step of determining the existence of the sensing target comprises: obtaining an echo signal of the integrated sensing base station, and obtaining a signal-to-noise ratio corresponding to the integrated sensing base station according to the echo signal; and determining the existence of the sensing target in the case that the signal-to-noise ratio exceeds a target threshold.

[0051] In the above same frequency interference evaluation method, by determining the existence of the sensing target, the available frequency band set is obtained, the first number of the first order same frequency neighbor area and the second number of the second order same frequency neighbor area corresponding to each frequency band division strategy are obtained, the first order interference lift and the second order interference lift corresponding to each element in the available frequency band set are obtained according to the first order interference lift and the second order interference lift.

[0052] For example, the formula for calculating the signal-to-noise ratio (SNR) is:

[0053]

[0054] In the above same frequency interference evaluation method, by determining the existence of the sensing target, the available frequency band set is obtained, the first number of the first order same frequency neighbor area and the second number of the second order same frequency neighbor area corresponding to each frequency band division strategy are obtained, the first order interference lift and the second order interference lift corresponding to each element in the available frequency band set are obtained according to the first order interference lift and the second order interference lift. is the radar scattering cross section, is the transmit power, is the receive antenna gain, is the transmit antenna gain, if the base station sensing mode is a self-transmit and self-receive mode, then . is the wavelength, R is the distance of the sensing target, and n is the cumulative number of the same beam in one scanning period. is the transmission duration of a single beam, L is the RV processing loss, is the interference, including noise, self-interference and networking interference.

[0055] In this embodiment, by obtaining the echo signal of the synesthesia integrated base station, the signal-to-noise ratio corresponding to the synesthesia integrated base station is obtained according to the echo signal. When the signal-to-noise ratio exceeds the target threshold, it is determined that the perception target exists, which can avoid resource waste and improve the reliability of the communication system.

[0056] In an exemplary embodiment, the first-order co-frequency neighboring cell is used to characterize the co-frequency interference between two adjacent synaesthesia integrated base stations in the network; the second-order co-frequency neighboring cell is used to characterize the co-frequency interference between two synaesthesia integrated base stations separated by one synaesthesia integrated base station in the network.

[0057] Optionally, in a telepathic network, first-order co-frequency neighboring cells refer to the co-channel interference generated between two adjacent telepathic base stations (i.e., physically adjacent, with no other base stations in between) using the same frequency band. Second-order co-frequency neighboring cells refer to the co-channel interference generated between two base stations separated by one telepathic base station (i.e., with another base station between them) using the same frequency band. It should be noted that since signal attenuation is significant after a distance of two base stations, and first-order and second-order co-channel interference are the most prevalent interference, interference between the current base station and base stations farther away is ignored here.

[0058] For example, Figure 3 Shown and Figure 4 As shown, Figure 3 and Figure 4 The following are schematic diagrams of the frequency division patterns obtained by using the 7-band and 9-band frequency division strategies. Different numbers represent the coverage areas of different perception frequency bands, and each base station uses one of the sub-bands. Figure 3 In the network, 7 frequency division is used. Although the beam directions of the No. 1 area of ​​the three base stations are staggered, there is still sidelobe interference. If you want to completely avoid the first-order co-channel interference, you need to change the sensing frequency of two of the No. 1 areas to other frequencies, that is, at least 9 different frequency bands are needed to avoid the first-order co-channel interference. Figure 4 After 9 frequency divisions, the sensing sector pattern can be rearranged, with the number 1 sectors of different base stations spaced further apart to avoid first-order interference. However, more sensing bandwidth divisions are not necessarily better. Given a fixed available sensing bandwidth, the more frequency bands are divided, the lower the sensing distance accuracy of a single station. Therefore, it is necessary to comprehensively consider the sensing bandwidth of a single station and the number of frequency bands divided in the network to maximize the overall network sensing performance.

[0059] In an example embodiment, the frequency band division numbers are arranged in descending order in the set of available frequency bands; and the first-order interference uplift and the second-order interference uplift corresponding to each element in the set of available frequency bands are obtained according to the spacing of the sense-integrated base station, the first number and the second number, including: for each remaining element arranged after the target element in the first place, the first-order interference uplift and the second-order interference uplift of the remaining element are obtained according to the spacing of the sense-integrated base station, the first number, the second number and the second-order interference uplift of the target element.

[0060] Optionally, when evaluating the interference, the target element arranged in the first place is taken as the evaluation reference, and the first-order interference uplift and the second-order interference uplift of each element arranged after the target element are obtained based on the second-order interference uplift of the target element.

[0061] In an example embodiment, the set of available frequency bands is represented as , each element representing a frequency band division number, and satisfying , the perception bandwidth under each frequency band division number is:

[0062]

[0063] , wherein M is the total available bandwidth of perception.

[0064] Suppose the spacing of the sense-integrated base station is , , the first-order co-frequency neighbor number in the first mode is , and the second-order co-frequency neighbor number is . Taking the second-order interference uplift of as the baseline, , the first-order interference uplift evaluation expression of

[0065]

[0066] , taking the second-order interference uplift of as the baseline, the second-order interference uplift evaluation expression of is:

[0067]

[0068] In this embodiment, by obtaining the first-order interference uplift and the second-order interference uplift of each remaining element arranged after the target element in the first place according to the spacing of the sense-integrated base station, the first number, the second number and the second-order interference uplift of the target element, the relative strength of interference between different frequency band division strategies can be accurately compared, so that the optimal frequency band division strategy can be quickly obtained.

[0069] In an example embodiment, the step of obtaining the total interference uplift corresponding to each element in the set of available frequency bands according to the first-order interference uplift and the second-order interference uplift comprises: summing the linear value of the first-order interference uplift corresponding to each element in the set of available frequency bands and the linear value of the second-order interference uplift corresponding to each element as the total interference uplift corresponding to each element.

[0070] For example, the total interference uplift can be represented as:

[0071]

[0072] wherein, represents the linear value of represents the linear value of

[0073] In an example embodiment, the method further comprises: determining a target frequency band division strategy from all frequency band division strategies according to the total interference uplift corresponding to all frequency band division strategies.

[0074] For example, assuming that the perceived total available bandwidth is 800M and the station spacing D = 1000m. The interference sizes of 15 frequency division and 8 frequency division are compared. It can be seen that , The first-order adjacent area and the second-order adjacent area under the two frequency divisions are shown in Table 1. Taking the second-order co-frequency adjacent area interference of 15 frequency division as the baseline, the first-order interference uplift, the total interference uplift of 15 frequency division, the first-order interference uplift, the second-order interference uplift and the total interference uplift of 8 frequency division are calculated, as shown in Table 1.

[0075] Table 1

[0076] 1st order co-channel neighbor 2nd order co-channel neighbor 1st order interference uplift 2nd order interference uplift Total interference uplift 15 frequency division 0 2 0 dB vs. baseline 0 dB 8 frequency division 2 4 6 dB > 3 dB > 12.5 dB

[0077] Based on the ranging accuracy formula , the perceived bandwidth of 100M and 50M makes the distance accuracy theoretically improve by 2 times, but the noise uplift of more than 12.5dB in the perceived SNR deterioration area makes the ranging accuracy deteriorate by more than 4.2 times, so there is no benefit in distance accuracy, and the perceived speed accuracy of this area will also be affected or even unable to detect the target point cloud. Considering that the station site parameters themselves have an error of 0.1m, the actual distance benefit is smaller. Therefore, in the case of a total perceived bandwidth of 800M, it can be concluded that the perceived performance of a single station with a perceived bandwidth of 50M is better than that of 100M. Based on this, the frequency band division strategy is selected as the 15 frequency division scheme.

[0078] In the embodiment, by determining a target frequency band division strategy from all frequency band division strategies according to the total interference uplift corresponding to all frequency band division strategies, the optimal frequency band division strategy can be quickly selected, and the accuracy and stability of the communication system are improved.

[0079] In one example embodiment, as shown in Figure 5 a co-sensing integrated base station, and a method for co-sensing integrated base station is provided, the method comprising the steps of:

[0080] S502: obtaining an echo signal of the co-sensing integrated base station, and obtaining a signal-to-noise ratio corresponding to the co-sensing integrated base station according to the echo signal; in a case where the signal-to-noise ratio exceeds a target threshold, determining that there is a sensing target.

[0081] S504: in a case where it is determined that there is a sensing target, obtaining a set of available frequency bands; the set of available frequency bands is used to represent a frequency band division strategy, and each element in the set of available frequency bands represents a number of frequency band divisions obtained according to a corresponding frequency band division strategy; wherein the number of frequency band divisions is arranged in descending order in the set of available frequency bands.

[0082] S506: obtaining a first number of first-order co-frequency neighbor areas and a second number of second-order co-frequency neighbor areas corresponding to each frequency band division strategy; wherein the first-order co-frequency neighbor area is used to represent co-frequency interference between two adjacent co-sensing integrated base stations in networking; and the second-order co-frequency neighbor area is used to represent co-frequency interference between two co-sensing integrated base stations separated by one co-sensing integrated base station in networking.

[0083] S508: for each remaining element after the target element in the first order, obtaining a first-order interference uplift and a second-order interference uplift of the remaining element according to the distance between the co-sensing integrated base stations, the first number, the second number, and the second-order interference uplift of the target element.

[0084] S510: taking the sum of the linear value of the first-order interference uplift and the linear value of the second-order interference uplift corresponding to each element in the set of available frequency bands as the total interference uplift corresponding to the element.

[0085] S512: determining a target frequency band division strategy from all frequency band division strategies according to the total interference uplift corresponding to each frequency band division strategy.

[0086] In this embodiment, by obtaining the set of available frequency bands in a case where it is determined that there is a sensing target, obtaining the first number of first-order co-frequency neighbor areas and the second number of second-order co-frequency neighbor areas corresponding to each frequency band division strategy, obtaining the first-order interference uplift and the second-order interference uplift corresponding to each element in the set of available frequency bands according to the distance between the co-sensing integrated base stations, the first number, and the second number, and obtaining the total interference uplift corresponding to each element in the set of available frequency bands according to the first-order interference uplift and the second-order interference uplift, the relative interference uplift between different frequency band division strategies can be quickly obtained, so that the optimal frequency band division strategy can be quickly determined, and time cost and computing resources can be saved.
