Technical Field

[0001] This application relates to the field of communication technology, and in particular to a symbol punching method, apparatus and electronic device. Background Technology

[0002] With the application of sensing technology, some network devices can also apply sensing functions in addition to communication functions. Such network devices can be called integrated sensing and communication network devices, or simply sensing and communication network devices. Network devices that have communication functions but no sensing functions can be called communication network devices.

[0003] In related technologies, the signal transmission of communication network equipment may interfere with the communication of inductive communication network equipment on the same frequency. Currently, in order to reduce interference, it is generally necessary to perform time slot puncturing on a large range of communication network equipment around the inductive communication network equipment. Time slot puncturing can be understood as disabling the time slot resource, making it impossible to communicate on that time slot resource. In related technologies, time slot puncturing is required on a large range of communication network equipment around the inductive communication network equipment, which has a significant impact on the communication performance of the communication network equipment, resulting in poor communication performance. Summary of the Invention

[0017] Based on the first interference detection sequence, interference detection is performed to obtain the first interference value;

[0018] If the first interference value is greater than the interference threshold value, at least a portion of the symbols in the predetermined time slot of the first network device are punched.

[0019] Fourthly, embodiments of this application provide an electronic device, including: a processor, a memory, and a program stored in the memory and executable on the processor, wherein when the program is executed by the processor, it implements the steps of the symbol punching method described in the first aspect.

[0032] 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, 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.

[0033] Introduction to the relevant technologies involved in this application:

[0034] Figure 1a , Figure 1b and Figure 1c The image shows a beamforming diagram. Current 4.9G communication network equipment (communication sites, corresponding to communication cells) can interfere with the signals of co-frequency inductive communication network equipment (inductive communication sites, corresponding to inductive communication cells) due to the emission of their upper lobes. For example, this interference can affect the RSSI level of pulse waves. This necessitates downlink time slot perforation of a large area of ​​communication sites surrounding the inductive communication site. This method severely impacts the downlink communication performance of the 4.9G communication site. In essence, the main idea behind existing communication cell perforation schemes is that inductive communication sites cannot measure which surrounding communication sites are interfering with them. To ensure sensing performance, inductive communication sites perform downlink time slot perforation to avoid interference from a large area of ​​surrounding communication cells. However, this perforation distance is too far, involves many communication sites, and has a large impact range. Furthermore, directly perforating surrounding communication cells leads to significant losses in communication cell capacity and coverage. Based on the above, this application provides an optimized symbol punching method. For communication cells with interference values ​​greater than the scene interference requirements, interference source avoidance is prioritized. For those that cannot be avoided, punching optimization is performed. Punching avoidance is only performed on communication sites that have interference with inductive communication sites, thereby improving the communication performance of communication cells.

[0035] See Figure 2 , Figure 2 This is a flowchart of a symbolic punching method provided in an embodiment of this application, which can be applied to a first network device, such as... Figure 2 As shown, the symbol punching method provided in this embodiment includes the following steps:

[0036] Step 201: Receive a first interference detection sequence sent by the second network device. The first interference detection sequence carries a first scenario interference requirement identifier, which is used to identify the interference threshold value of the serving cell of the second network device.

[0037] Step 202: Perform interference detection based on the first interference detection sequence to obtain the first interference value.

[0038] Step 203: If the first interference value is greater than the interference threshold, punch holes in at least a portion of the symbols in the predetermined time slot of the first network device.

[0039] The second network device can be a sensing and communication device, that is, a network device that integrates sensing and communication functions. The first network device can be a communication network device. As an example, the first network device can also be a communication network device within a preset distance of the second network device. If the first interference value is greater than the interference threshold value indicated by the first scenario interference requirement identifier, it can be considered that the first network device is significantly interfering with the second network device, exceeding the interference threshold that the second network device can tolerate. In this case, the first network device can be considered an interfering device for the second network device.

[0040] In this embodiment, it is necessary to detect interference sources in the second network device. The second network device can transmit a first interference detection sequence, and the first network device can detect the first interference detection sequence. If the first interference value detected by the first network device is greater than an interference threshold, at least a portion of the symbols in a predetermined time slot of the first network device are punctured. That is, the first network device only punctures at least a portion of the symbols in the predetermined time slot when it is determined that the interference to the second network device is significant. In this way, communication of at least a portion of the symbols in the predetermined time slot by the first network device can be prohibited, reducing interference to the second network device and improving the communication performance of the second network device. At the same time, it can avoid direct symbol puncturing by the first network device, ensuring the communication performance of the first network device. Simultaneously, it can reduce the number of first network devices directly puncturing symbols around the second network device, ensuring the communication performance of first network devices around the second network device.

[0041] In some embodiments, the first interference detection sequence further carries a first transmission parameter, which includes at least one of the following: the transmission power of the second network device and the antenna tilt angle of the second network device;

[0042] When the first interference value exceeds the interference threshold, at least a portion of the symbols in a predetermined time slot of the first network device are punctured, including:

[0043] If the first interference value is greater than the interference threshold, the second transmission parameters of the first network device are adjusted according to the first transmission parameters, with the goal of reducing the interference of the first network device to the second network device, and within the preset transmission parameter adjustment range. The second transmission parameters include at least one of the following: the transmission power of the first network device and the antenna tilt angle of the first network device.

[0044] After each adjustment of the second transmission parameters of the first network device, upon receiving the second interference detection sequence sent by the second network device, interference detection is performed based on the second interference detection sequence to obtain a second interference value, which is less than the first interference value.

[0045] If the second interference value is greater than the interference threshold, at least some of the symbols in the predetermined time slot are punched.

[0046] In other words, during the adjustment of the transmission parameters of the first network device, the adjustment range of the transmission parameters cannot exceed the preset transmission parameter adjustment range to ensure the transmission performance of the first network device. As an example, the preset transmission parameter adjustment range may include at least one of the following: a maximum allowable transmission power adjustment threshold and a maximum allowable tilt angle adjustment threshold. The preset transmission parameter adjustment range can be set according to actual needs, historical experience, etc., without specific limitations. For example, as an example, the maximum allowable tilt angle adjustment threshold could be 10 degrees, and the maximum allowable transmission power adjustment threshold could be the result of subtracting the minimum transmission power requirement of the first network device from its current transmission power. The minimum transmission power requirement of the first network device can be understood as the minimum transmission power requirement to ensure the transmission performance of the first network device. As an example, adjusting the transmission power of the first network device can be done by reducing the transmission power of the first network device, and the reduction in the transmission power of the first network device shall not exceed the maximum allowable transmission power adjustment threshold in the preset transmission parameter adjustment range.

[0047] In this embodiment, when the first interference value is greater than the interference threshold, the transmission power of the first network device can be adjusted, that is, interference avoidance can be achieved by adjusting the transmission parameters. After each adjustment of the transmission power of the first network device, the second interference detection sequence sent by the second network device can be received, and interference detection can be performed on the second interference detection sequence to obtain the second interference value. If the second interference value is greater than the interference threshold, it can be understood that the interference value is still greater than the interference threshold after interference avoidance by adjusting the transmission parameters. At least some symbols in the predetermined time slot can be punched, that is, punching avoidance can be performed to avoid interference to the second network device.

[0048] In some embodiments, when the second interference value is greater than an interference threshold, punching holes in at least a portion of the symbols in a predetermined time slot includes:

[0049] If the physical resource block (PRB) utilization rate of the first network device is lower than the preset utilization rate when the second interference value is greater than the interference threshold, then at least some symbols in the predetermined time slot will be punched.

[0050] To avoid interference, the symbols of the first network device are punched. Since the first network device cannot communicate on the punched symbols, in this embodiment of the application, the physical resource block (PRB) utilization rate of the first network device needs to be detected before punching the symbols. If the PRB utilization rate of the first network device is lower than the preset utilization rate, it indicates that the load of the first network device is low. In this case, at least some symbols in the predetermined time slot can be punched to reduce the impact on the communication of the first network device.

[0051] In some embodiments, when the first interference value is greater than an interference threshold, the second transmission parameters of the first network device are adjusted according to the first transmission parameters, with the aim of reducing interference from the first network device to the second network device, while not exceeding a preset transmission parameter adjustment range. This includes:

[0052] If the first interference value is greater than the interference threshold, the path loss between the second network device and the first network device is determined based on the first transmission parameters and the first transmission parameters of the first network device; the first transmission parameters include at least one of the following: the received power of the first interference detection sequence and the antenna tilt angle of the first network device;

[0053] If the result of subtracting path loss from the transmit power of the first network device is greater than the interference threshold, the second transmit parameters of the first network device are adjusted according to the first transmit parameters and the preset transmit parameter adjustment range, with the goal of reducing the interference of the first network device to the second network device, and without exceeding the preset transmit parameter adjustment range.

[0054] It is understandable that the first transmission parameters and the first transmission parameters can be compared to obtain the path loss between the second network device and the first network device. If the result of subtracting the path loss from the transmission power of the first network device is greater than the interference threshold, the second transmission parameters of the first network device are adjusted according to the first transmission parameters and the preset transmission parameter adjustment range, with the goal of reducing the interference of the first network device to the second network device. Under the condition that the preset transmission parameter adjustment range is not exceeded, the second transmission parameters of the first network device are adjusted to reduce the interference to the second network device while ensuring the communication performance of the first network device.

[0055] In some embodiments, the method further includes:

[0056] If the second interference value is less than or equal to the interference threshold, stop adjusting the second transmission parameter.

[0057] In other words, if the detected second interference value is less than or equal to the interference threshold after adjusting the transmission parameters of the first network device, it means that the interference has been reduced and has fallen below the interference threshold. In this case, the adjustment of the second transmission parameters can be stopped to ensure the communication quality of the first network device.

[0058] In some embodiments, the method further includes:

[0059] If the first interference value is less than or equal to the interference threshold, maintain normal time slot scheduling of the first network device.

[0060] If the first interference value is less than or equal to the interference threshold, it means that the interference of the first network device to the second network device is small, and there is no need to drill holes to avoid it. It is sufficient to maintain the normal time slot scheduling of the first network device to ensure the communication performance of the first network device.

[0061] In some embodiments, punching at least a portion of the symbols in a predetermined time slot of the first network device includes:

[0062] Punch holes in the first half of the symbols of each time slot in the predetermined time slot of the first network device.

[0063] In other words, instead of punching all the symbols in the predetermined time slot, only the first half of the symbols in each predetermined time slot are punched. This reduces interference to the second network device on the one hand, and ensures the communication performance of the first network device on the other.

[0064] For example, such as Figure 3 As shown, the predetermined time slots of the first network device include time slot 0 and time slot 5, both of which are downlink time slots. The first half of the symbols in time slot 0 and time slot 5 are punctured, and the first network device disables the first half of the symbols in downlink time slot 0 and downlink time slot 5. This reduces interference to the second network device in these symbols, so that the second network device can be aware of them. The second half of the symbols in downlink time slot 0 and downlink time slot 5 of the first network device can be scheduled normally to ensure the communication performance of the first network device.

[0065] The process of the above method will be specifically described below with some specific embodiments.

[0066] This application provides a communication wave symbol puncturing scheme based on interference source detection. According to the interference source detection feature sequence (i.e., interference detection sequence / interference sequence) sent by the inductive communication cell, the interference detection sequence may carry the city identifier, device identifier, cell identifier (the identifier of the serving cell of the second network device), transmission feature identifier (first transmission parameter), and scene interference requirement identifier, etc., corresponding to the second network device. Surrounding communication cells detect the interference detection sequence. When the detected interference value is greater than the interference threshold indicated by the scene interference requirement identifier, correction is first performed based on the transmission feature identifier. If the correction still cannot meet the scene interference requirement, interference avoidance algorithm optimization is performed based on the transmission feature identifier. If the avoidance still cannot meet the scene interference requirement, symbol puncturing optimization is then performed. This scheme can significantly reduce the number of punctured cells and improve spectrum efficiency. The main steps of this embodiment include, but are not limited to: generating the interference source detection feature sequence; sending the interference source detection feature sequence; receiving the interference source detection feature sequence; decision correction of the interference source detection feature sequence; interference avoidance of the interference source detection feature sequence; and puncturing avoidance of the interference source detection feature sequence. Figure 4 As shown, the solution flow of this embodiment is as follows:

[0067] First: Interference detection sequence generation

[0068] A communication wave symbol punching scheme based on interference source detection requires the inductive communication cell to send an interference detection feature sequence (interference source detection feature sequence / interference detection sequence) to surrounding communication cells. The field configuration of the interference detection sequence is shown in Table 1: symbols 1-2 (X1-X2) are city identifiers (identifiers of the city where the base station is located); symbols 3-8 are base station identifiers (X3-X8); symbols 9-10 (X9-X10) are cell identifiers; symbols 11-12 (X11-X12) are transmission feature identifiers, identifying information such as transmission power and tilt angle; symbols 13-14 (X13-X14) are scene interference requirement identifiers, identifying the threshold value (interference threshold value) for interference from surrounding communication cells to the inductive communication cell.

[0069] Table 1 Interference Detection Sequences

[0070]

[0071] Secondly: the transmission of the interference detection sequence

[0072] To facilitate symbol-by-symbol detection at the receiver, the transmitter sends the characteristic interference detection sequence on the symbol closest to the gap in the time domain. The transmission position varies depending on the special subframe configuration; in the frequency domain, the entire bandwidth is used, and the interference detection sequence is transmitted across the full bandwidth to ensure reception accuracy. When the special subframe configuration is 10:2:2, it is fixed at symbol 10; when the special subframe configuration is 6:6:2, it is fixed at symbol 6.

[0073] Then: Reception of the interference detection sequence

[0074] The communication cell, acting as the receiving end, receives and detects the interference detection sequence. When the detected interference value is greater than the interference threshold indicated by the scene interference requirement identifier of symbols X13-X14 in the interference detection sequence, the interference detection sequence X1-X12 is retained; when the detected interference value is less than or equal to the interference threshold indicated by the scene interference requirement identifier of symbols X13-X14 in the interference detection sequence, symbols X1-X12 in the interference detection sequence are deleted; the cells in the retained interference detection sequences X1-X12 are sorted according to the degree of interference.

[0075] Furthermore: Decision correction for interference detection sequences:

[0076] The communication cell extracts information from symbols X11-X12 in the interference detection sequence, compares it with its own cell's transmit power and downtilt angle, and obtains a correction value (including path loss). If the corrected interference (e.g., the transmit power of the first network device minus the path loss) is reduced to below the interference threshold identified by the scene interference requirement identifier, no optimization is performed; otherwise, the following interference avoidance optimization is performed.

[0077] Then: Interference avoidance of the interference detection sequence

[0078] The communication cell performs transmit power and downtilt angle avoidance based on the cell indicated by the X9-X10 symbols in the extracted interference detection sequence. The transmit power is gradually reduced and the downtilt angle is gradually reduced. If the interference drops below the scene interference requirements after the avoidance algorithm is implemented, the optimization stops; otherwise, the following hole punching optimization is performed.

[0079] Finally: Drilling avoidance in interference detection sequences

[0080] If the interference in a communication cell still exceeds the interference threshold value indicated by the scene interference requirement after interference avoidance, and the PRB utilization rate is lower than the preset utilization rate (for example, the preset utilization rate can be 70%), then hole punching avoidance is performed.

[0081] This application provides a communication wave symbol puncturing method based on interference source detection. The method involves surrounding communication cells using the interference source detection feature sequence sent by the sensing communication cell to inversely assess their own interference to the sensing communication cell. The interference assessment result is then compared with the interference threshold value identified by the scene interference requirement identifier to determine whether puncturing optimization is necessary. This application's solution can significantly reduce the number of puncturing operations in communication cells, improving network resource utilization and user experience.

[0082] In this application's embodiment, interference source detection feature sequences are used to identify the information of the inductive communication cell, which is then used to assess the interference of the communication cell to the inductive communication cell and to perform precise puncturing, thus solving the current defect of full puncturing of downlink time slots 0 and 5 of communication cells within a preset range (e.g., within 20 kilometers) around 4.9G inductive sites. Furthermore, a detailed scheme for puncturing communication wave symbols based on interference source detection is proposed. Compared with related technical solutions, this application's embodiment adds interference source detection, allowing for puncturing judgment based on the interference source detection results, significantly reducing the number of punctured cells, improving network resource utilization, and enhancing user experience. For this application's embodiment, a simulation test can be conducted using manual frame offset adjustment. Within 20km, 40% of the cells are interfered with; 20% are resolved through avoidance algorithms, and only 30% of the cells trigger puncturing.

[0083] The solution in this application can detect the characteristic sequence of the interference source to reversely assess whether the communication cell interferes with the sensing communication cell and the degree of its impact. It reduces the interference of the communication cell to the sensing cell through three methods: decision correction, avoidance optimization, and hole punching optimization, thereby reducing the number of holes punched in the communication cell, improving the utilization rate of existing network resources, and providing users with better network services.
