Technical Field

[0001] This application relates to the field of wireless communication technology, and in particular to a method, apparatus, base station and storage medium for waveform scheduling based on inductive fusion. Background Technology

[0002] Sensor fusion is a technology that utilizes existing base stations to simultaneously achieve communication and radar sensing functions. By balancing the needs of communication and sensing, it achieves integrated communication and sensing as well as diversified functions based on inheriting or reconstructing the existing network architecture.

[0003] In the fusion of communication and sensing technologies, base stations need to transmit hybrid beams (communication beams + sensing beams) to achieve basic wireless communication functions while also being able to perform radar detection of objects in the environment and sense parameters such as their distance, motion status, and speed.

[0004] Currently, the design of sensing fusion waveforms is still under discussion. How to design sensing fusion waveforms and optimize communication and radar sensing performance is an urgent problem to be solved. Summary of the Invention

[0005] This application provides a method, apparatus, base station, and storage medium for scheduling waveforms in sensing fusion, which are used to adjust the sensing fusion waveforms in sensing fusion to achieve joint optimization of sensing performance.

[0006] In a first aspect, embodiments of this application provide a first inductive fusion waveform scheduling method applied to a base station, the method comprising:

[0007] Based on the first signal-to-noise ratio of the sub-channel, the equivalent signal-to-noise ratio of each communication beam is determined; and based on the second signal-to-noise ratio of the sub-channel, the equivalent signal-to-noise ratio of each sensing beam is determined; wherein, the first signal-to-noise ratio is the signal-to-noise ratio received by the communication terminal, and the second signal-to-noise ratio is the echo reception signal-to-noise ratio;

[0008] For any communication beam, the measurement parameters of the communication beam in communication indicators are determined based on the equivalent signal-to-noise ratio of the communication beam; and for any sensing beam, the measurement parameters of the sensing beam in sensing indicators are determined based on the equivalent signal-to-noise ratio of the sensing beam.

[0009] If the measurement parameters of the corresponding indicator of the first beam are not within the corresponding preset indicator range, then a target sub-channel is selected from the sub-channels corresponding to the second beam, and the target sub-channel is assigned to the first beam; wherein, if the first beam is a communication beam, then the corresponding indicator is a communication indicator, and the second beam is a sensing beam; if the first beam is a sensing beam, then the corresponding indicator is a sensing indicator, and the second beam is a communication beam.

[0010] In some optional implementations, if the first beam is a communication beam and the second beam is a sensing beam, then selecting a target sub-channel from the sub-channels corresponding to the second beam includes:

[0011] From the sub-channels corresponding to the sensing beam, select the M sub-channels with the highest first signal-to-noise ratio as the target sub-channels; or

[0012] From the sub-channels corresponding to the sensing beam, select the N sub-channels with the lowest second signal-to-noise ratio as the target sub-channels; or

[0013] From the sub-channels corresponding to the sensing beam, select the sub-channel with a first signal-to-noise ratio greater than a first signal-to-noise ratio threshold and a second signal-to-noise ratio less than a second signal-to-noise ratio threshold as the target sub-channel.

[0014] In some optional implementations, if the first beam is a sensing beam and the second beam is a communication beam, then selecting a target sub-channel from the sub-channels corresponding to the second beam includes:

[0015] From the sub-channels corresponding to the communication beam, select the X sub-channels with the highest second signal-to-noise ratio as the target sub-channels; or

[0016] From the sub-channels corresponding to the communication beam, select the Y sub-channels with the smallest first signal-to-noise ratio as the target sub-channels; or

[0017] From the sub-channels corresponding to the communication beam, select the sub-channel with a second signal-to-noise ratio greater than the third signal-to-noise ratio threshold and a first signal-to-noise ratio less than the fourth signal-to-noise ratio threshold as the target sub-channel.

[0018] In some alternative implementations, the first signal-to-noise ratio of the sub-channel is determined by the following method:

[0019] A probe message is sent to the communication terminal so that the communication terminal determines the first signal-to-noise ratio of the sub-channel based on the probe message;

[0020] The first signal-to-noise ratio of the sub-channel received by the communication terminal.

[0021] In some alternative implementations, the second signal-to-noise ratio of the sub-channel is determined by the following method:

[0022] After transmitting a signal to the sensing terminal, the echo signal corresponding to the sensing terminal is received by the echo receiving array;

[0023] Based on the echo signal, the second signal-to-noise ratio of the sub-channel is determined.

[0024] In some alternative implementations, before assigning the target sub-channel to the first beam, the method further includes:

[0025] Determine the estimated equivalent signal-to-noise ratio of the first beam if the target sub-channel is added to the first beam;

[0026] It is determined that the increase in the estimated equivalent signal-to-noise ratio of the first beam relative to the equivalent signal-to-noise ratio of the first beam is greater than a preset increase.

[0027] In some alternative implementations, after assigning the target sub-channel to the first beam, the method further includes:

[0028] After a preset time period, the steps of determining the equivalent signal-to-noise ratio of each communication beam based on the first signal-to-noise ratio of the sub-channel and determining the equivalent signal-to-noise ratio of each sensing beam based on the second signal-to-noise ratio of the sub-channel are re-executed.

[0029] Secondly, embodiments of this application provide a first type of inductive fusion waveform scheduling device, the device comprising:

[0030] An equivalent signal-to-noise ratio (SNR) determination module is used to determine the equivalent SNR of each communication beam based on a first SNR of the sub-channel; and to determine the equivalent SNR of each sensing beam based on a second SNR of the sub-channel; wherein the first SNR is the SNR received by the communication terminal, and the second SNR is the SNR received by the echo.

[0031] The index parameter determination module is used to determine the measurement parameters of the communication index of any communication beam based on the equivalent signal-to-noise ratio of the communication beam; and to determine the measurement parameters of the sensing beam in the sensing index based on the equivalent signal-to-noise ratio of the sensing beam for any sensing beam.

[0032] The waveform scheduling module is used to select a target sub-channel from the sub-channels corresponding to the second beam and assign the target sub-channel to the first beam if the measurement parameters of the corresponding indicator of the first beam are not within the corresponding preset indicator range; wherein, if the first beam is a communication beam, the corresponding indicator is a communication indicator and the second beam is a sensing beam; if the first beam is a sensing beam, the corresponding indicator is a sensing indicator and the second beam is a communication beam.

[0033] Thirdly, embodiments of this application provide a base station, including at least one processor and at least one memory, wherein the memory stores a computer program, and when the program is executed by the processor, the processor performs the sensing fusion waveform scheduling method described in any of the first aspects above.

[0034] Fourthly, embodiments of this application provide a computer-readable storage medium storing a computer program executable by a processor, which, when run on the processor, causes the processor to execute the synesthetic waveform scheduling method described in any of the first aspects above.

[0035] The above scheme, since the signal-to-noise ratio (SNR) received by the communication terminal corresponding to the sub-channel (first SNR) reflects its communication performance, the equivalent SNR characterizing the current communication quality of the communication beam can be determined based on the first SNR, and thus the measurement parameters of the communication beam under the communication index (i.e., the specific values ​​under a certain communication index) can be determined. Since the echo reception SNR (second SNR) corresponding to the sub-channel reflects its sensing performance, the equivalent SNR characterizing the current sensing quality of the sensing beam can be determined based on the second SNR, and thus the measurement parameters of the sensing beam under the sensing index (i.e., the specific values ​​under a certain sensing index) can be determined. By comparing the measurement parameters of each beam under the corresponding index with the corresponding preset index range (i.e., index requirements), it can be determined whether each beam can meet the current communication / sensing requirements. For beams that cannot meet the requirements, a target sub-channel is selected from another beam and assigned to that beam. By adjusting the sensing fusion waveform, the overall communication and sensing quality is improved, and the joint optimization of sensing performance is achieved. Attached Figure Description

[0050] Sensor fusion is a technology that utilizes existing base stations to simultaneously achieve communication and radar sensing functions.

[0051] See Figure 1 As shown, in the sensing fusion technology, the base station needs to transmit a hybrid beam (communication beam + sensing beam) to achieve basic wireless communication functions, while also being able to perform radar detection on objects in the environment and sense parameters such as their distance, motion state, and speed.

[0052] Currently, the design of sensing fusion waveforms is still under discussion. How to design sensing fusion waveforms and optimize communication and radar sensing performance is an urgent problem to be solved.

[0053] In view of this, embodiments of this application propose a sensing fusion waveform scheduling method, apparatus, base station, and storage medium. The method includes: determining the equivalent signal-to-noise ratio (SNR) of each communication beam based on a first SNR of a sub-channel; and determining the equivalent SNR of each sensing beam based on a second SNR of the sub-channel; wherein the first SNR is the signal-to-noise ratio received by the communication terminal, and the second SNR is the echo reception SNR; for any communication beam, determining the measurement parameters of the communication beam in communication indicators based on the equivalent SNR of the communication beam; and for any... The sensing beam, based on its equivalent signal-to-noise ratio, determines the measurement parameters of the sensing beam for a sensing index. If the measurement parameters of a first beam for a corresponding index are not within the corresponding preset index range, a target sub-channel is selected from the sub-channels corresponding to the second beam, and the target sub-channel is assigned to the first beam. Wherein, if the first beam is a communication beam, the corresponding index is a communication index, and the second beam is a sensing beam; if the first beam is a sensing beam, the corresponding index is a sensing index, and the second beam is a communication beam.

[0054] The above scheme, since the signal-to-noise ratio (SNR) received by the communication terminal corresponding to the sub-channel (first SNR) reflects its communication performance, the equivalent SNR characterizing the current communication quality of the communication beam can be determined based on the first SNR, and thus the measurement parameters of the communication beam under the communication index (i.e., the specific values ​​under a certain communication index) can be determined. Since the echo reception SNR (second SNR) corresponding to the sub-channel reflects its sensing performance, the equivalent SNR characterizing the current sensing quality of the sensing beam can be determined based on the second SNR, and thus the measurement parameters of the sensing beam under the sensing index (i.e., the specific values ​​under a certain sensing index) can be determined. By comparing the measurement parameters of each beam under the corresponding index with the corresponding preset index range (i.e., index requirements), it can be determined whether each beam can meet the current communication / sensing requirements. For beams that cannot meet the requirements, a target sub-channel is selected from another beam and assigned to that beam. By adjusting the sensing fusion waveform, the overall communication and sensing quality is improved, and the joint optimization of sensing performance is achieved.

[0055] The technical solution of this application and how it solves the above-mentioned technical problems will be described in detail below with reference to the accompanying drawings and specific embodiments. The following specific embodiments can be combined with each other, and the same or similar concepts or processes may not be described again in some embodiments.

[0056] Figure 2 A flowchart illustrating the first synesthetic fusion waveform scheduling method provided in this application embodiment is shown below. Figure 2 As shown, it includes the following steps:

[0057] Step S201: Determine the equivalent signal-to-noise ratio of each communication beam based on the first signal-to-noise ratio of the sub-channel; and determine the equivalent signal-to-noise ratio of each sensing beam based on the second signal-to-noise ratio of the sub-channel; wherein the first signal-to-noise ratio is the signal-to-noise ratio received by the communication terminal, and the second signal-to-noise ratio is the echo reception signal-to-noise ratio.

[0058] In this embodiment, since the signal-to-noise ratio (SNR) received by the communication terminal corresponding to the sub-channel (first SNR) reflects its communication performance, the equivalent SNR characterizing the current communication quality of the communication beam can be determined based on the first SNR; since the echo reception SNR (second SNR) corresponding to the sub-channel reflects its sensing performance, the equivalent SNR characterizing the current sensing quality of the sensing beam can be determined based on the second SNR.

[0059] See Figure 3 As shown, the base station maps the spatial, temporal, and frequency domain resources of the signal transmitter (A1, A2, A3...An is the antenna array of the base station signal transmitter) to logical sub-channels, with different beams corresponding to different sub-channels;

[0060] The second signal-to-noise ratio (SINR) based on sub-channel 1,1 1,1 The second SINR of sub-channels 1 and 2 1,2 The second SINR of sub-channels 1 and 3 1,3 and the second SINR of sub-channels 1 and 4 1,4 Determine the equivalent signal-to-noise ratio of sensing beam 1;

[0061] First SINR based on subchannels 1 and 3 1,3 The first SINR of sub-channel 2,1 2,1 The first SINR of sub-channel 2,2 2,2 and the first SINR of subchannel n,2 n,2 Determine the equivalent signal-to-noise ratio of communication beam 1;

[0062] The equivalent signal-to-noise ratio of other beams is determined in the same way, and will not be elaborated on here.

[0063] The above Figure 3 This is just an example; in practice, there may be more or fewer sub-channels, more or fewer beams, and different correspondences, etc.

[0064] This embodiment does not limit the specific implementation method for determining the equivalent signal-to-noise ratio; it is merely an example. ; where γ eff-i γ is the equivalent signal-to-noise ratio of beam i. j Let be the signal-to-noise ratio of the j-th sub-channel corresponding to beam i, J be the total number of sub-channels corresponding to beam i, and β be the tuning factor.

[0065] Step S202: For any communication beam, determine the measurement parameters of the communication beam in communication indicators based on the equivalent signal-to-noise ratio of the communication beam; and for any sensing beam, determine the measurement parameters of the sensing beam in sensing indicators based on the equivalent signal-to-noise ratio of the sensing beam.

[0066] In practice, since the equivalent signal-to-noise ratio of a communication beam reflects the current communication quality, the measurement parameters of the communication beam under a certain communication index (i.e., the specific values ​​under a certain communication index) can be determined based on the equivalent signal-to-noise ratio of the communication beam.

[0067] Since the equivalent signal-to-noise ratio of the sensing beam reflects the current sensing quality, the measurement parameters of the sensing beam for a sensing index (i.e., the specific values ​​under a certain sensing index) can be determined based on the equivalent signal-to-noise ratio of the sensing beam.

[0068] This embodiment does not specifically limit the communication indicators. The communication indicators may include one or more indicators, such as rate, bit error rate, latency, etc.

[0069] Based on the calculation formula (mapping relationship) between equivalent SINR and communication indicators, the measurement parameters are determined; taking bit error rate as an example:

[0070] Among them, CBR i Here, γ is the bit error rate measurement parameter for beam i, M is the modulation order, and γ is the bit error rate. eff-i Let be the equivalent signal-to-noise ratio of beam i.

[0071] This embodiment does not specifically limit the perception indicators. The perception indicators may include one or more indicators, such as detection distance, false alarm rate, etc.

[0072] Based on the calculation formula (mapping relationship) between equivalent SINR and sensing indicators, the measurement parameters are determined; taking detection distance as an example:

[0073] Among them, R max-i P is the sensing distance measurement parameter for beam i. t Where λ is the transmit power, G is the transmit / receive antenna gain, λ is the signal wavelength, and γ is the transmit power. eff-i Let σ be the equivalent signal-to-noise ratio of beam i, and σ be the equivalent reflective surface area; σ = KT0B n F0, K are preset parameters, T0 is the period, B n F0 represents the bandwidth, and F0 represents the frequency.

[0074] The above-mentioned indicators and calculation methods are only illustrative examples. Other indicators that reflect communication or sensing requirements may also be used in practice. This embodiment does not impose any specific limitations on them.

[0075] Step S203: If the measurement parameters of the corresponding indicator of the first beam are not within the corresponding preset indicator range, then select a target sub-channel from the sub-channel corresponding to the second beam and assign the target sub-channel to the first beam; wherein, if the first beam is a communication beam, then the corresponding indicator is a communication indicator and the second beam is a sensing beam; if the first beam is a sensing beam, then the corresponding indicator is a sensing indicator and the second beam is a communication beam.

[0076] In this embodiment, after determining the measurement parameters of each beam in the corresponding index, the measurement parameters of each beam in the corresponding index are compared with the corresponding preset index range (i.e. index requirements) to determine whether each beam can meet the current communication / sensing requirements.

[0077] For example, communication indicators include rate and bit error rate. If the measured parameter of the rate of the communication beam (actual rate) is not within the preset rate range (e.g., the actual rate is too low), or the measured parameter of the bit error rate (actual bit error rate) is not within the preset bit error rate range (e.g., the actual bit error rate is too high), it is determined that the measured parameter of the communication indicator of the communication beam is not within the corresponding preset indicator range, and the communication beam cannot meet the current communication requirements.

[0078] The sensing indicators include detection range and false alarm rate. If the measured parameter of the detection range of the sensing beam (actual detection range) is not within the preset detection range (e.g., the actual detection range is too small), or the measured parameter of the false alarm rate (actual false alarm rate) is not within the preset false alarm rate range (e.g., the actual false alarm rate is too large), it is determined that the measured parameter of the sensing beam is not within the corresponding preset indicator range, and the sensing beam cannot meet the current sensing requirements.

[0079] In practice, other communication and sensing indicators can be set. During actual comparison, it can be determined that the beam's measurement parameters for the corresponding indicator are not within the corresponding preset indicator range when one indicator is not within the corresponding range; or it can be determined that the beam's measurement parameters for the corresponding indicator are not within the corresponding preset indicator range when all indicators are not within the corresponding range. This embodiment does not make specific limitations on this.

[0080] If it is determined that the measurement parameters of the communication beam are not within the corresponding preset index range, it means that the communication beam cannot meet the current communication requirements. The communication quality can be improved by selecting a suitable target sub-channel from the sensing beam and assigning it to the communication beam.

[0081] If it is determined that the measurement parameters of the sensing beam for the corresponding index are not within the corresponding preset index range, it means that the sensing beam cannot meet the current sensing requirements. The sensing quality can be improved by selecting a suitable target sub-channel from the communication beam and assigning it to the sensing beam.

[0082] The two processes described above do not affect or interfere with each other and can be adjusted in both directions. That is to say, it is possible to allocate sub-channels suitable for communication functions from the sensing beam to the communication beam, and it is also possible to allocate sub-channels suitable for sensing functions from the communication beam to the sensing beam, thereby achieving joint optimization of sensing performance.

[0083] In some alternative implementations, joint subchannel estimation can be based on multiple-input multiple-output (MIMO) or orthogonal frequency division multiplexing (OFDM) techniques.

[0084] The above scheme, since the signal-to-noise ratio (SNR) received by the communication terminal corresponding to the sub-channel (first SNR) reflects its communication performance, the equivalent SNR characterizing the current communication quality of the communication beam can be determined based on the first SNR, and thus the measurement parameters of the communication beam under the communication index (i.e., the specific values ​​under a certain communication index) can be determined. Since the echo reception SNR (second SNR) corresponding to the sub-channel reflects its sensing performance, the equivalent SNR characterizing the current sensing quality of the sensing beam can be determined based on the second SNR, and thus the measurement parameters of the sensing beam under the sensing index (i.e., the specific values ​​under a certain sensing index) can be determined. By comparing the measurement parameters of each beam under the corresponding index with the corresponding preset index range (i.e., index requirements), it can be determined whether each beam can meet the current communication / sensing requirements. For beams that cannot meet the requirements, a target sub-channel is selected from another beam and assigned to that beam. By adjusting the sensing fusion waveform, the overall communication and sensing quality is improved, and the joint optimization of sensing performance is achieved.

[0085] See Figure 4 As shown, this is an application scenario provided in this embodiment. The base station is equipped with a transmitting antenna array, an echo receiving array, and a waveform scheduling and processing unit; the communication terminal is equipped with a communication receiving antenna array.

[0086] The first signal-to-noise ratio of the aforementioned sub-channel needs to be obtained through interaction between the base station and the communication terminal;

[0087] The second signal-to-noise ratio of the aforementioned sub-channel needs to be obtained through interaction between the base station and the sensing terminal;

[0088] For details, please refer to the following: Figure 5 as well as Figure 6 Example.

[0089] Figure 5 An interactive flowchart of the first signal-to-noise ratio determination process provided in the embodiments of this application is shown below. Figure 5 As shown, it includes the following steps:

[0090] Step S501: The base station sends a probe message to the communication terminal through the transmitting antenna array.

[0091] Step S502: The communication terminal determines the first signal-to-noise ratio of the sub-channel based on the probe message.

[0092] Step S503: The communication terminal sends the first signal-to-noise ratio of the sub-channel to the base station.

[0093] For example, the waveform scheduling processing unit of the base station controls the transmitting antenna array to send probe messages to the communication terminal through control commands;

[0094] The communication terminal receives the probe message through its communication receiving antenna array; the communication terminal evaluates the first signal-to-noise ratio of each sub-channel and sends the first signal-to-noise ratio of each sub-channel to the waveform scheduling processing unit of the base station.

[0095] Figure 6 The interactive flowchart of the second signal-to-noise ratio determination process provided in the embodiments of this application is as follows: Figure 6 As shown, it includes the following steps:

[0096] Step S601: The base station transmits signals to the sensing terminal through the transmitting antenna array.

[0097] Step S602: The base station receives the echo signal corresponding to the sensing terminal through the echo receiving array.

[0098] Step S603: The base station determines the second signal-to-noise ratio of the sub-channel based on the echo signal.

[0099] For example, the waveform scheduling processing unit of the base station controls the transmitting antenna array to transmit signals to the sensing terminal through control commands;

[0100] After passing through the sensing terminal, the sensing echo (echo signal) is returned; the base station receives the echo signal through the echo receiving array; the waveform scheduling and processing unit of the base station evaluates the second signal-to-noise ratio of each sub-channel.

[0101] In some optional implementations, where the first beam is a communication beam and the second beam is a sensing beam, the selection of the target sub-channel in step S203 can be achieved in, but is not limited to, the following ways:

[0102] From the sub-channels corresponding to the sensing beam, select the M sub-channels with the highest first signal-to-noise ratio as the target sub-channels; or

[0103] From the sub-channels corresponding to the sensing beam, select the N sub-channels with the lowest second signal-to-noise ratio as the target sub-channels; or

[0104] From the sub-channels corresponding to the sensing beam, select the sub-channel with a first signal-to-noise ratio greater than a first signal-to-noise ratio threshold and a second signal-to-noise ratio less than a second signal-to-noise ratio threshold as the target sub-channel.

[0105] In practice, if the first beam is a communication beam and the second beam is a sensing beam, meaning the communication beam cannot meet the current communication needs, it is necessary to select a suitable target sub-channel from the sensing beam and assign it to the communication beam to improve communication quality.

[0106] As mentioned above, the first signal-to-noise ratio (SNR) of a sub-channel reflects its communication performance; the second SNR of a sub-channel reflects its sensing performance. Therefore, one or more target sub-channels can be determined based on the first and second SNRs of the sub-channels.

[0107] For example, by selecting the M sub-channels with the highest first signal-to-noise ratio from the sub-channels corresponding to the sensing beam, that is, the M sub-channels with the best communication function, and taking them as target sub-channels, the target sub-channels are assigned to the communication beam, and the communication quality will be significantly improved after adjustment.

[0108] By selecting the N sub-channels with the lowest second signal-to-noise ratio from the sub-channels corresponding to the sensing beam, which are also the N sub-channels with the worst sensing function, and using them as target sub-channels, the impact on sensing quality is relatively small after the target sub-channels are assigned to the communication beam.

[0109] By selecting sub-channels from the sub-channels corresponding to the sensing beam that have a first signal-to-noise ratio greater than a first signal-to-noise ratio threshold and a second signal-to-noise ratio less than a second signal-to-noise ratio threshold (i.e., sub-channels with good communication function but poor sensing function), and using these sub-channels as target sub-channels, the impact on sensing quality after adjustment is small, while the improvement in communication quality is more significant.

[0110] This embodiment does not limit the specific values ​​of M and N, nor does it limit the specific values ​​of the first signal-to-noise ratio threshold and the second signal-to-noise ratio threshold. They can be set according to the specific application scenario. Generally speaking, the first signal-to-noise ratio threshold is greater than the second signal-to-noise ratio threshold, so that there will be better performance improvement after adjustment.

[0111] The above methods for determining the target sub-channel are merely illustrative examples. In practice, the target sub-channel can be determined simply by referring to the first signal-to-noise ratio / second signal-to-noise ratio of the sub-channel.

[0112] In some optional implementations, where the first beam is a sensing beam and the second beam is a communication beam, the selection of the target sub-channel in step S203 can be achieved in, but is not limited to, the following ways:

[0113] From the sub-channels corresponding to the communication beam, select the X sub-channels with the highest second signal-to-noise ratio as the target sub-channels; or

[0114] From the sub-channels corresponding to the communication beam, select the Y sub-channels with the smallest first signal-to-noise ratio as the target sub-channels; or

[0115] From the sub-channels corresponding to the communication beam, select the sub-channel with a second signal-to-noise ratio greater than the third signal-to-noise ratio threshold and a first signal-to-noise ratio less than the fourth signal-to-noise ratio threshold as the target sub-channel.

[0116] In practice, if the first beam is a sensing beam and the second beam is a communication beam, meaning the sensing beam cannot meet the current communication needs, it is necessary to select a suitable target sub-channel from the communication beam and assign it to the sensing beam to improve the sensing quality.

[0117] As mentioned above, the first signal-to-noise ratio (SNR) of a sub-channel reflects its communication performance; the second SNR of a sub-channel reflects its sensing performance. Therefore, one or more target sub-channels can be determined based on the first and second SNRs of the sub-channels.

[0118] For example, by selecting the X sub-channels with the highest second signal-to-noise ratio from the sub-channels corresponding to the communication beam, that is, the X sub-channels with the best sensing function, and using them as target sub-channels, the target sub-channels are assigned to the sensing beam, and the sensing quality will be significantly improved after adjustment.

[0119] By selecting the Y sub-channels with the smallest first signal-to-noise ratio from the sub-channels corresponding to the communication beam, which are also the Y sub-channels with the worst communication function, and using them as target sub-channels, the target sub-channels are assigned to the sensing beam. After adjustment, the impact on communication quality is relatively small.

[0120] By selecting sub-channels from the sub-channels corresponding to the communication beam that have a second signal-to-noise ratio greater than the third signal-to-noise ratio threshold and a first signal-to-noise ratio less than the fourth signal-to-noise ratio threshold (i.e., sub-channels with poor communication function but good sensing function), and using these sub-channels as target sub-channels, the impact on communication quality after adjustment is small, while the improvement in sensing quality is more significant.

[0121] This embodiment does not limit the specific values ​​of X and Y, nor does it limit the specific values ​​of the third and fourth signal-to-noise ratio thresholds. They can be set according to specific application scenarios. Generally speaking, the third signal-to-noise ratio threshold is greater than the fourth signal-to-noise ratio threshold, which will result in better performance improvement after adjustment.

[0122] The above methods for determining the target sub-channel are merely illustrative examples. In practice, the target sub-channel can be determined simply by referring to the first signal-to-noise ratio / second signal-to-noise ratio of the sub-channel.

[0123] Figure 7 This is a flowchart illustrating the second synesthetic fusion waveform scheduling method provided in the embodiments of this application, as shown below. Figure 7 As shown, it includes the following steps:

[0124] Step S701: Determine the equivalent signal-to-noise ratio of each communication beam based on the first signal-to-noise ratio of the sub-channel; and determine the equivalent signal-to-noise ratio of each sensing beam based on the second signal-to-noise ratio of the sub-channel; wherein the first signal-to-noise ratio is the signal-to-noise ratio received by the communication terminal, and the second signal-to-noise ratio is the echo reception signal-to-noise ratio.

[0125] Step S702: For any communication beam, determine the measurement parameters of the communication beam in communication indicators based on the equivalent signal-to-noise ratio of the communication beam; and for any sensing beam, determine the measurement parameters of the sensing beam in sensing indicators based on the equivalent signal-to-noise ratio of the sensing beam.

[0126] Step S703: If the measurement parameters of the corresponding indicator of the first beam are not within the corresponding preset indicator range, then select the target sub-channel from the sub-channel corresponding to the second beam; wherein, if the first beam is a communication beam, then the corresponding indicator is a communication indicator and the second beam is a sensing beam; if the first beam is a sensing beam, then the corresponding indicator is a sensing indicator and the second beam is a communication beam.

[0127] The specific implementation of steps S701 to S703 can be found in the above embodiments, and will not be repeated here.

[0128] Step S704: For any beam, determine the estimated equivalent signal-to-noise ratio of the first beam if the target sub-channel is added to the first beam.

[0129] During implementation, if the base station itself does not have sufficient resources, there may be situations where the communication quality and perception quality are not up to standard. In this case, adjustments may be needed continuously, but the quality improvement may not be significant.

[0130] Based on this, in order to perform waveform scheduling in the fusion of induction more effectively, this embodiment first estimates the equivalent signal-to-noise ratio (SNR) of the first beam after scheduling before scheduling.

[0131] Step S705: Determine whether the increase in the estimated equivalent signal-to-noise ratio of the first beam relative to the equivalent signal-to-noise ratio of the first beam is greater than a preset increase.

[0132] For example, the increase in the estimated equivalent signal-to-noise ratio of the first beam compared to the equivalent signal-to-noise ratio before the first beam is scheduled is determined, and the increase represents the gain brought about by the scheduling of the first beam.

[0133] By setting a preset increase that represents the gain limit, the determined increase is compared with the preset increase.

[0134] If the determined increase is greater than the preset increase, it means that the gain brought by the scheduling of the first beam is relatively obvious, and the target sub-channel can be assigned to the first beam, that is, step S706 is executed.

[0135] If the determined increase is not greater than the preset increase, it means that the gain brought by the scheduling of the first beam is not significant enough. In order to improve the scheduling efficiency, the target sub-channel will not be assigned to the first beam.

[0136] Step S706: If so, the target sub-channel is assigned to the first beam.

[0137] The above scheme determines the increase in the estimated equivalent signal-to-noise ratio (SNR) of the first beam compared to the equivalent SNR before the first beam is scheduled. This increase represents the gain brought about by the scheduling of the first beam. The determined increase is compared with the preset increase. If the determined increase is greater than the preset increase, it means that the gain brought about by the scheduling of the first beam is relatively significant. The target sub-channel can be assigned to the first beam, thereby more effectively performing waveform scheduling in the sensing fusion.

[0138] Figure 8 A flowchart illustrating the third synesthetic fusion waveform scheduling method provided in this application embodiment is shown below. Figure 8 As shown, it includes the following steps:

[0139] Step S801: Determine the equivalent signal-to-noise ratio of each communication beam based on the first signal-to-noise ratio of the sub-channel; and determine the equivalent signal-to-noise ratio of each sensing beam based on the second signal-to-noise ratio of the sub-channel; wherein the first signal-to-noise ratio is the signal-to-noise ratio received by the communication terminal, and the second signal-to-noise ratio is the echo reception signal-to-noise ratio.

[0140] Step S802: For any communication beam, determine the measurement parameters of the communication beam in communication indicators based on the equivalent signal-to-noise ratio of the communication beam; and for any sensing beam, determine the measurement parameters of the sensing beam in sensing indicators based on the equivalent signal-to-noise ratio of the sensing beam.

[0141] Step S803: If the measurement parameters of the corresponding indicator of the first beam are not within the corresponding preset indicator range, then select the target sub-channel from the sub-channel corresponding to the second beam and assign the target sub-channel to the first beam; wherein, if the first beam is a communication beam, then the corresponding indicator is a communication indicator and the second beam is a sensing beam; if the first beam is a sensing beam, then the corresponding indicator is a sensing indicator and the second beam is a communication beam.

[0142] Step S804: Determine whether the current time is more than the preset time since the last scheduling was completed.

[0143] For example, due to changes in the wireless environment, the signal-to-noise ratio of a sub-channel may change (time-varying channel). That is, a sub-channel may have good communication quality at time T1, but its communication quality may deteriorate significantly at time T2. Therefore, after completing one sensing fusion waveform scheduling, it is impossible to guarantee that it will adapt to subsequent environmental changes.

[0144] Based on this, this embodiment provides a dynamic sensing fusion waveform scheduling method. After scheduling is completed, it is determined whether the current time is more than a preset time interval from the scheduling completion time. If the preset time interval is exceeded, step S801 is re-executed, that is, a new scheduling cycle is started; if the preset time interval is not exceeded, the process continues to wait. For example, a periodic timer can be started after scheduling is completed. After the periodic timer expires, it indicates that the preset time interval has been exceeded, and the sensing fusion waveform scheduling of the next cycle is performed.

[0145] The above scheme determines whether the time elapsed since the scheduling completion time exceeds a preset time after the scheduling is completed. If the preset time elapses, a new scheduling cycle is started, thereby adapting to changes in the wireless environment. It adaptively and dynamically adjusts the sensing fusion waveform according to the time-varying channel and maintains optimized communication and sensing performance according to channel changes.

[0148] The index parameter determination module 902 is used to determine the measurement parameters of the communication index of any communication beam based on the equivalent signal-to-noise ratio of the communication beam; and to determine the measurement parameters of the sensing beam in the sensing index based on the equivalent signal-to-noise ratio of the sensing beam for any sensing beam.

[0149] The waveform scheduling module 903 is used to select a target sub-channel from the sub-channels corresponding to the second beam and assign the target sub-channel to the first beam if the measurement parameters of the corresponding indicator of the first beam are not within the corresponding preset indicator range; wherein, if the first beam is a communication beam, the corresponding indicator is a communication indicator and the second beam is a sensing beam; if the first beam is a sensing beam, the corresponding indicator is a sensing indicator and the second beam is a communication beam.

[0162] After transmitting a signal to the sensing terminal, the echo signal corresponding to the sensing terminal is received by the echo receiving array;

[0163] Based on the echo signal, the second signal-to-noise ratio of the sub-channel is determined.
