Description

Technical Field

[0001] This application relates to the field of communication technology, and in particular to an information exchange method, base station, device and storage medium. Background Technology

[0002] In a sensory network, an integrated sensory base station senses objects by sending and receiving sensing signals. These sensing signals consume the time and frequency resources of the communication signals. Considering the interference from surrounding communication base stations on the sensing signals of the sensory base station, and to ensure sensing performance, surrounding communication base stations cannot send communication signals.

[0003] Existing technical solutions involve statically punching holes in the communication base station equipment surrounding the sensing base station. At the corresponding symbols of the sensing signal, the surrounding communication base stations do not transmit data, thus avoiding interference between the communication signals and the sensing signal and ensuring optimal sensing performance. This solution results in a fixed and maximized performance loss for the surrounding communication base stations, in exchange for the enhanced sensing performance of the sensing base station.

[0004] However, as mentioned above, if there are no or only a few sensing targets in the covered low-altitude airspace, or if the sensing targets are not evenly distributed, such as the target objects only existing in one or a few beam directions, statically punching holes in the communication base station equipment around the sensing base station will occupy too much of the communication base station equipment resources, and will not maximize the utilization of air interface resources, affecting the service rate, latency and other communication user perception performance.

Detailed Implementation

[0034] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0035] Figure 1 This is one of the flowcharts illustrating the information interaction method provided in the embodiments of this application, such as... Figure 1 As shown in the figure, this application provides an information interaction method, the execution subject of which can be a sensing base station. The method includes: Step 100: Based on the period of the sensing signal, send the sensing feature sequence to the communication base station.

[0036] Among them, the sensing feature sequence is used to indicate the feature information of the sensing signal sent by the sensing base station, and is used by the communication base station to perform interference avoidance processing on the sensing signal.

[0037] Specifically, in this embodiment, a sensing base station refers to a base station that has both communication and sensing functions. It can send sensing signals (such as scanning beams or tracking beams) to detect targets, while also carrying communication services. The communication base station can be any base station with communication functions in the vicinity of the sensing base station.

[0038] The sensing base station can send a sensing feature sequence to the communication base station according to the period of the sensing signal, so as to achieve coordinated scheduling between the two.

[0039] The period of the sensing signal refers to the fixed time interval at which the sensing base station sends sensing signals, which may include the period of sensing signal scanning and the period of tracking.

[0040] For example, if the sensing beam needs to be transmitted completely within the period of the sensing signal, the sensing base station will transmit the sensing feature sequence in a special time slot of the first 5ms frame at the beginning of the period (either in the downlink (DL) symbol or the guard period (GP) symbol of the special time slot).

[0041] The sensing feature sequence is used to indicate the characteristic information of the sensing signal sent by the sensing base station. It can be represented by multiple bits or combinations of multiple bits to represent different types of characteristic information of the sensing signal. Different types of characteristic information can be defined with different numbers of bits according to the actual deployment of commercial networks.

[0042] In some embodiments, an Integrated Sensing and Communication Reference Signal (ISAC-RS) can be defined, through which sensing feature sequences can be transmitted.

[0043] In some embodiments, the sensed feature sequence can be transmitted via a Remote Interference Management Reference Signal (RIM-RS); In particular, RIM-RS adds a bit to distinguish between the far-end interference detection sequence and the sensing feature sequence.

[0044] Specifically, RIM-RS is a traditional reference signal used between communication base stations for remote interference detection and management, mainly used to solve interference problems caused by long distances between base stations.

[0045] In this embodiment of the application, an additional bit can be added to the existing RIM-RS, for example, 1 bit can be added to the first bit of the RIM-RS as an identifier bit to distinguish the sensing feature sequence used for sensing interference detection from the sequence used for communication remote interference detection (remote interference detection sequence).

[0046] For example, if the first bit is 0, the sequence in the RIM-RS is a far-end interference detection sequence, and the subsequent bits are defined according to the far-end interference detection mechanism; if the first bit is 1, the sequence in the RIM-RS is a sensing feature sequence, and the subsequent bits are defined according to the sensing feature sequence in the embodiments of this application.

[0047] In this way, communication base stations can handle two types of interference simultaneously without adding new signal types, reducing the complexity of protocol modifications.

[0048] In some embodiments, the characteristic information of the sensed signal may include one or more of the following: (1) Periodic information of the sensing signal. The characteristic information of the sensing signal may include the periodic information of the sensing signal, so that the communication base station can determine the period of the sensing signal sent by the sensing base station based on the sensing characteristic sequence.

[0049] In some implementations, the start position of the sensing period can be aligned by modulo operation of the System Frame Number (SFN) (SFNmod T) to ensure time synchronization between the sensing base station and the communication base station, where T is the period length of the sensing signal.

[0050] (2) Time-domain information of the sensing signal. The characteristic information of the sensing signal may include the time-domain information of the sensing signal, such as the time slot number occupied by the sensing signal (e.g., D0 / D5 time slot) or the number of symbols (e.g., the first 7 symbols), so that the communication base station can determine the time-domain resource location of the sensing signal sent by the sensing base station based on the sensing characteristic sequence.

[0051] (3) Frequency domain information of the sensing signal. The characteristic information of the sensing signal may include the frequency domain information of the sensing signal, such as the bandwidth resources occupied by the sensing signal. Thus, the communication base station can determine the frequency domain resource location of the sensing signal sent by the sensing base station based on the sensing characteristic sequence.

[0052] (4) Spatial information of the sensing signal. The characteristic information of the sensing signal may include the spatial information of the sensing signal, such as the beam direction of the sensing signal transmission. Thus, the communication base station can determine the spatial resource location of the sensing signal transmitted by the sensing base station based on the sensing characteristic sequence.

[0053] (5) Identification information of sensing base stations. The characteristic information of sensing signals may include the identification information of sensing base stations, such as 5G base station identifier (Global NodeB Identifier, gNB ID) or cell identity (CellID), so that the communication base station can determine the sensing base station that needs to send sensing signals based on the sensing characteristic sequence.

[0054] Based on the distance between the communication base station and the sensing base station, the GP symbol, DL symbol, uplink (UL) symbol, or regular uplink time slot detection and sensing feature sequence of the communication base station in a special time slot can be set.

[0055] After receiving the sensing feature sequence sent by the sensing base station, the communication base station can determine whether to perform interference avoidance processing on the sensing signal and how to perform interference avoidance processing on the sensing signal based on the feature information of the sensing signal in the sensing feature sequence.

[0056] The information interaction method provided in this application embodiment sends a sensing feature sequence to a communication base station through a sensing base station. The sensing feature sequence is used to indicate the feature information of the sensing signal sent by the sensing base station. Thus, the communication base station can flexibly perform interference avoidance processing on the sensing signal according to the feature information of the sensing signal, thereby reducing resource occupation and improving resource utilization.

[0057] Figure 2 This is a second flowchart illustrating the information interaction method provided in the embodiments of this application, such as... Figure 2 As shown in the figure, this application provides an information interaction method, the execution subject of which can be a communication base station. The method includes: Step 200: Receive the sensing feature sequence sent by the sensing base station. The sensing feature sequence is used to indicate the feature information of the sensing signal sent by the sensing base station.

[0058] Step 201: Based on the sensing feature sequence, perform interference avoidance processing on the sensing signal.

[0059] Specifically, in this embodiment, a sensing base station refers to a base station that has both communication and sensing functions. It can send sensing signals (such as scanning beams or tracking beams) to detect targets, while also carrying communication services. The communication base station can be any base station with communication functions in the vicinity of the sensing base station.

[0060] The sensing base station can send a sensing feature sequence to the communication base station according to the period of the sensing signal, so as to achieve coordinated scheduling between the two.

[0061] The period of the sensing signal refers to the fixed time interval at which the sensing base station sends sensing signals, which may include the period of sensing signal scanning and the period of tracking.

[0062] For example, if the sensing beam needs to be transmitted completely within the period of the sensing signal, the sensing base station will transmit the sensing feature sequence in a special time slot (either the DL symbol or the GP symbol in the special time slot) during the first 5ms frame at the beginning of the period.

[0063] The sensing feature sequence is used to indicate the characteristic information of the sensing signal sent by the sensing base station. It can be represented by multiple bits or combinations of multiple bits to represent different types of characteristic information of the sensing signal. Different types of characteristic information can be defined with different numbers of bits according to the actual deployment of the commercial network.

[0064] In some embodiments, an ISAC-RS can be defined to transmit the sensing feature sequence.

[0065] In some embodiments, the sensing feature sequence can be transmitted via RIM-RS; In particular, RIM-RS adds a bit to distinguish between the far-end interference detection sequence and the sensing feature sequence.

[0066] Specifically, RIM-RS is a traditional reference signal used between communication base stations for remote interference detection and management, mainly used to solve interference problems caused by long distances between base stations.

[0067] In this embodiment of the application, an additional bit can be added to the existing RIM-RS, for example, 1 bit can be added to the first bit of the RIM-RS as an identifier bit to distinguish the sensing feature sequence used for sensing interference detection from the sequence used for communication remote interference detection (remote interference detection sequence).

[0068] For example, if the first bit is 0, the sequence in the RIM-RS is a far-end interference detection sequence, and the subsequent bits are defined according to the far-end interference detection mechanism; if the first bit is 1, the sequence in the RIM-RS is a sensing feature sequence, and the subsequent bits are defined according to the sensing feature sequence in the embodiments of this application.

[0069] In this way, communication base stations can handle two types of interference simultaneously without adding new signal types, reducing the complexity of protocol modifications.

[0070] In some embodiments, the characteristic information of the sensed signal may include one or more of the following: (1) Periodic information of the sensing signal. The characteristic information of the sensing signal may include the periodic information of the sensing signal, so that the communication base station can determine the period of the sensing signal sent by the sensing base station based on the sensing characteristic sequence.

[0071] In some implementations, the starting position of the sensing period can be aligned using SFN mod T operation to ensure time synchronization between the sensing base station and the communication base station, where T is the period length of the sensing signal.

[0072] (2) Time-domain information of the sensing signal. The characteristic information of the sensing signal may include the time-domain information of the sensing signal, such as the time slot number occupied by the sensing signal (e.g., D0 / D5 time slot) or the number of symbols (e.g., the first 7 symbols), so that the communication base station can determine the time-domain resource location of the sensing signal sent by the sensing base station based on the sensing characteristic sequence.

[0073] (3) Frequency domain information of the sensing signal. The characteristic information of the sensing signal may include the frequency domain information of the sensing signal, such as the bandwidth resources occupied by the sensing signal. Thus, the communication base station can determine the frequency domain resource location of the sensing signal sent by the sensing base station based on the sensing characteristic sequence.

[0074] (4) Spatial information of the sensing signal. The characteristic information of the sensing signal may include the spatial information of the sensing signal, such as the beam direction of the sensing signal transmission. Thus, the communication base station can determine the spatial resource location of the sensing signal transmitted by the sensing base station based on the sensing characteristic sequence.

[0075] (5) Identification information of the sensing base station. The characteristic information of the sensing signal may include the identification information of the sensing base station, such as gNB ID or Cell ID, so that the communication base station can determine the sensing base station that needs to send the sensing signal based on the sensing characteristic sequence.

[0076] Based on the distance between the communication base station and the sensing base station, the GP symbol, DL symbol, UL symbol, or regular UL time slot detection and sensing feature sequence of the communication base station in a special time slot can be set.

[0077] After receiving the sensing feature sequence sent by the sensing base station, the communication base station can determine whether to perform interference avoidance processing on the sensing signal and how to perform interference avoidance processing on the sensing signal based on the feature information of the sensing signal in the sensing feature sequence.

[0078] The information interaction method provided in this application embodiment sends a sensing feature sequence to a communication base station through a sensing base station. The sensing feature sequence is used to indicate the feature information of the sensing signal sent by the sensing base station. Thus, the communication base station can flexibly perform interference avoidance processing on the sensing signal according to the feature information of the sensing signal, thereby reducing resource occupation and improving resource utilization.

[0079] In some embodiments, when receiving sensing feature sequences transmitted by multiple sensing base stations, the method further includes: Perform union processing on sensing feature sequences transmitted by multiple sensing base stations whose signal strength exceeds a preset threshold; Based on the sensing feature sequence, interference avoidance processing is performed on the sensing signal, including: Based on the sensor feature sequence after union processing, interference avoidance processing is performed on the sensor signal corresponding to the sensor feature sequence after union processing.

[0080] Specifically, when a communication base station receives sensing feature sequences from multiple sensing base stations, the communication base station can dynamically coordinate resources to avoid interference through signal strength threshold judgment and union processing mechanism.

[0081] After receiving sensing feature sequences from multiple sensing base stations, the communication base station can first measure the signal strength (e.g., received power P) of each sequence. If the signal strength of a sensing feature sequence from a certain sensing base station exceeds a preset threshold, it is determined that its sensing signal may cause significant interference to communication services, and subsequent union processing can be performed; conversely, if the signal strength of a sensing feature sequence from a certain sensing base station is lower than the preset threshold, the sensing feature sequence is ignored.

[0082] For all sensing feature sequences that exceed the threshold, the communication base station can perform union processing on the feature information of the sensing signals indicated in each sensing feature sequence to generate a unified interference avoidance area.

[0083] For example, when performing union processing on the time-domain information of the sensing signal: if the sensing base station A instructs "send sensing signal for the first 7 symbols of time slot D0", and the sensing base station B instructs "send sensing signal for the last 7 symbols of time slot D5", then the communication base station needs to avoid the first 7 symbols of time slot D0 and the last 7 symbols of time slot D5.

[0084] For example, when performing union processing on the frequency domain information of the sensed signal: if sensing base station A occupies a bandwidth of 0~20MHz and sensing base station B occupies a bandwidth of 20~40MHz, then the communication base station needs to avoid the frequency domain resources of the 0~40MHz bandwidth.

[0085] By performing union processing on the sensing feature sequences sent by multiple sensing base stations, it can be ensured that the communication base station avoids all possible interference areas and avoids missing the sensing signal coverage area in the case of multiple sensing base stations.

[0086] In some embodiments, interference avoidance processing is performed on the sensed signal based on the sensed feature sequence, including: Based on the signal strength of arbitrary sensing feature sequences, determine the interference avoidance processing method corresponding to the arbitrary sensing feature sequences. Based on the interference avoidance processing method corresponding to arbitrary sensing feature sequences, interference avoidance processing is performed on the sensing signals corresponding to arbitrary sensing feature sequences.

[0087] Specifically, in this embodiment of the application, the communication base station can determine whether to perform interference avoidance processing on the sensing signal corresponding to a certain sensing feature sequence based on the signal strength (such as the received power) of that sensing feature sequence, or flexibly select different interference avoidance processing methods, thereby minimizing the loss of communication performance while ensuring sensing performance.

[0088] In some implementations, multiple signal strength ranges can be set, each corresponding to a different interference avoidance processing method. If the signal strength of a certain sensing feature sequence falls within a certain signal strength range, the communication base station will perform interference avoidance processing on the sensing signal based on the feature information of the sensing signal corresponding to the sensing feature sequence and the interference avoidance processing method corresponding to the signal strength range.

[0089] For example, setting a high threshold Thred high and low threshold Thred low The received power P represents the signal strength of the sensing feature sequence. When the received power P of a certain sensing feature sequence is greater than or equal to Thred... high In this case, the communication base station can determine that the interference avoidance processing method corresponding to the sensing feature sequence is to perform a puncturing process, and execute the puncturing process according to the sensing signal corresponding to the sensing feature sequence; when the power P of a certain sensing feature sequence is less than Thred high And greater than Thred low In this case, the communication base station can determine that the interference avoidance processing method corresponding to the sensing feature sequence is to reduce the transmission power of the communication signal, and reduce the transmission power of the communication signal according to the transmission time slot of the sensing signal corresponding to the sensing feature sequence; when the power P of a certain sensing feature sequence is less than or equal to Thredlow In such cases, the communication base station may not need to perform interference avoidance processing on the sensed signal.

[0090] It is understandable that for the sensing feature sequence after union processing, which includes multiple sensing feature sequences, the interference avoidance processing method corresponding to the sensing feature sequence can be determined according to the signal strength of each sensing feature sequence, and the sensing signal corresponding to the sensing feature sequence can be subjected to interference avoidance processing according to the interference avoidance processing method corresponding to the sensing feature sequence.

[0091] By using signal strength classification and judgment, communication base stations can dynamically select interference avoidance methods, thereby improving the utilization rate of communication resources while ensuring the sensing performance of the sensing base station.

[0092] In some embodiments, the methods for interfering with the sensed signal include one or more of the following: (1) Based on the feature information of the sensing signal, the punching process is executed.

[0093] Specifically, after receiving the sensing feature sequence sent by the sensing base station, the communication base station can dynamically skip (punch) the time domain resources occupied by the sensing signal based on the feature information of the sensing signal.

[0094] For example, a communication base station can dynamically skip the time domain resources occupied by a sensing signal based on the time domain information and / or periodic information of the sensing signal.

[0095] The punching process for communication base stations can be at the symbol level or at the time slot level, depending on the capabilities of the user terminals in the cell.

[0096] For example, if the user terminal supports symbol-level scheduling, it can only avoid the specific symbols occupied by the sensing signal, and the remaining symbols can still schedule communication services; if the user terminal only supports time slot-level scheduling, it can skip the entire time slot occupied by the sensing signal.

[0097] (2) Based on the characteristic information of the sensing signal, reduce the transmission power of the communication signal.

[0098] Specifically, after receiving the sensing feature sequence sent by the sensing base station, the communication base station can reduce the transmission power of the communication signal sent by the communication base station based on the feature information of the sensing signal.

[0099] For example, a communication base station can reduce the transmission power of communication signals transmitted on the time domain resources occupied by the sensed signal.

[0100] Alternatively, a communication base station can reduce the transmission power of communication signals transmitted on the frequency domain resources occupied by the sensed signal.

[0101] (3) Based on the characteristic information of the sensing signal, the user's communication services are scheduled according to the priority of distance.

[0102] Specifically, after receiving the sensing feature sequence sent by the sensing base station, the communication base station can schedule the user's communication services based on the feature information of the sensing signal and the distance between the user and the base station.

[0103] For example, communication base stations can prioritize scheduling users closer to the communication base station (such as users in the cell center) on the time domain resources and / or frequency domain resources occupied by sensing signals, because their path loss is smaller and they can maintain communication quality even with lower transmission power; and reduce or suspend scheduling for users at the coverage edge to avoid significant degradation of their communication performance due to interference from sensing signals.

[0104] (4) Based on the characteristic information of the sensing signal, spatial beam avoidance is performed on the sensing signal.

[0105] Specifically, after receiving the sensing feature sequence sent by the sensing base station, the communication base station can perform spatial beam avoidance on the sensing signal based on the feature information of the sensing signal.

[0106] For example, a communication base station can use beamforming to direct the beam of a sensing signal to a non-interference area based on the spatial information of the sensing signal (such as the beam direction of the sensing signal).

[0107] In scenarios where the distribution of sensing targets is uneven, communication base stations only need to avoid the beam in the direction of the sensing target, while communication can still be carried out efficiently in other directions.

[0108] (5) Based on the characteristic information of the sensing signal, the frequency domains of the communication signal and the sensing signal are separated.

[0109] Specifically, after receiving the sensing feature sequence sent by the sensing base station, the communication base station can avoid the overlap of bandwidth occupied by the communication signal and the sensing signal by allocating frequency domain resources based on the feature information of the sensing signal.

[0110] For example, a communication base station can determine the bandwidth occupied by the sensing signal based on the frequency domain information of the sensing signal, and then schedule communication services on the bandwidth outside the bandwidth occupied by the sensing signal.

[0111] Through the dynamic combination of the above-mentioned strategies, the embodiments of this application realize the fine coordination of communication signal and sensing signal resources, solve the problem of serious waste of traditional static punching resources, and provide an efficient and flexible interference control mechanism for integrated communication and sensing networks.

[0112] The information interaction methods provided in the above embodiments are further illustrated below through specific examples: This embodiment establishes an information interaction mechanism between the sensing base station and the communication base station, and defines a sensing feature sequence (ISAC-RS). The feature sequence includes information such as the sensing signal transmission period, the sensing signal transmission time slot / number of symbols, and the sensing signal bandwidth.

[0113] Figure 3 This is a flowchart illustrating the synesthetic interference feature sequence detection mechanism provided in the embodiments of this application, as follows: Figure 3 As shown, the sensing base station sends the sensing signal transmission information to the communication base station according to the configurable cycle. After obtaining the relevant information, the communication base station dynamically adjusts the transmission of the communication signal according to the sensing signal occupancy status of the sensing base station.

[0114] Figure 4 This is a schematic diagram of the transmission and reception location of the sensing feature sequence provided in the embodiments of this application.

[0115] like Figure 4 As shown, the sensing base station transmits sensing feature sequences according to the sensing signal scanning and tracking cycle (hereinafter referred to as the sensing signal cycle). If the complete transmission of the sensing beam is required within the sensing signal cycle, the sensing feature sequence is transmitted in a special time slot (which can be the DL symbol or GP symbol in the special time slot) of the first 5ms frame at the beginning of the cycle. The feature sequence (ISAC-RS) can be, but is not limited to, RIM-RS. If there are two special time slots in this 5ms period, the sensing feature sequence is transmitted in the first special time slot.

[0116] After a communication base station receives a sensing feature sequence in a special time slot GP symbol, special time slot DL symbol, special time slot UL symbol, or regular uplink time slot (depending on the distance between the communication base station and the sensing base station), such as after detecting ISAC-RS, it schedules / does not schedule communication service resources in the D0 and D5 time slots of subsequent subframes within the current sensing signal period. The non-scheduling method can be at the symbol level or at the time slot level, depending on the capabilities of the communication terminals in the cell.

[0117] Figure 5 This is a schematic diagram illustrating the definition of the sensing feature sequence format provided in an embodiment of this application. To further subdivide different sensing signal transmission methods (e.g., sensing period, sensing bandwidth, number of sensing symbols, etc.) so that communication base stations can more effectively avoid puncturing, relevant information can be carried in the sensing feature sequence to notify the communication base station. Different bits or combinations represent different sensing signal transmission characteristics. One possible approach is as follows: Figure 5 As shown.

[0118] After detecting the sensing feature sequence, the communication base station parses the bit information carried in the sensing feature sequence to obtain the sensing signal transmission pattern of the sensing base station. Figure 5The period, bandwidth, and number of symbols in the sensing signal can be defined with different bit counts based on the actual deployment of the commercial network. To reduce the number of bits in the sensing signal symbols, a Symbol Length and Interval Value (SLIV) encoding method can be used. Furthermore, to avoid scenarios where multiple adjacent sensing base stations transmit the same ISAC-RS sequence, leading to the communication base station receiving signal power from multiple stations and misjudging the sum as exceeding the threshold, a gNB ID field is added to the feature sequence to identify different gNBs. The purpose of this field is to randomize the ISAC-RS sequence, eliminating the need for the communication base station to identify which sensing gNB the ISAC-RS originated from.

[0119] Figure 6 This is a schematic diagram illustrating the meaning of sequence grouping and indication provided in the embodiments of this application, such as... Figure 6 As shown, the receiving communication base station may receive sensing feature sequences from multiple sensing base stations. A union processing step is needed for the stronger sensing feature sequences that exceed the decision threshold. For example, if sensing feature sequence 1 indicates that the sensing signal is transmitted in the first 20ms + the first 20M bandwidth + the first 7 symbols of an 80ms period, and sensing feature sequence 2 indicates that the sensing signal is transmitted in the second 20ms + the second 20M bandwidth + the last 7 symbols of an 80ms period, then the communication base station needs to leave all 14 symbols of the D0 and D5 time slots (the first 40ms + the first 40M bandwidth of the sensing period) unscheduled for communication. For the remaining 60M bandwidth and the last 40ms, the D0 and D5 time slots can be used to schedule communication services.

[0120] To ensure that the start positions of the sensing signal transmission cycles at the transmitting and receiving ends are aligned, SFN mod T is used as a reference, where T represents the length of the sensing cycle.

[0121] Figure 7 This is a schematic diagram illustrating RIM-RS as a perceptual feature sequence format definition provided in the embodiments of this application, such as... Figure 7 As shown, further, if RIM-RS is selected as the sensing feature sequence (ISAC-RS), in order to distinguish it from the feature sequences of far-end interference, RIM-RS can be further grouped. One possible method is to add 1 bit to the first bit of the sequence for differentiation: 0: Remote interference detection in communication; 1: Sensory interference detection.

[0122] If the first bit is 0, the sequence is a communication long-end interference detection sequence, and subsequent bits are defined according to the long-end interference detection mechanism. If the first bit is 1, it is a sensing interference detection feature sequence, and subsequent bits can be parsed according to the field meanings defined in this embodiment.

[0123] Furthermore, after receiving the sensing feature sequence, the base station can select different puncturing methods based on the signal strength of the received sensing feature sequence. It can also reduce the transmit power of scheduled communication services in time slots D0 and D5, further reducing communication performance loss. For example, a high threshold Thred can be set. high and low threshold Thred low The power of the syn-sensory characteristic sequence measured by the communication base station is P: If P>Thred high : Perform the drilling process; If Thred high >P>Thred low Reduce the transmit power of scheduled communication services in slots D0 and D5, or combine this with priority scheduling of nearby users.

[0124] In addition to time-domain punching and power reduction, spatial beamforming avoidance or frequency-domain staggering can also be used to avoid interference with the sensing signal.
