Detailed ways

The embodiment of the present application provides a communication anti-interference method, network equipment, terminal equipment and storage medium, which are used to provide multiple synchronous frequency points for terminal equipment to perform network access operations, avoiding interference of a synchronous frequency point, and No other secondary synchronization frequency points can access the network for communication, resulting in the failure of terminal devices to access the network and communicate.

In order to enable those skilled in the art to better understand the solution of the present application, the technical solution in the embodiment of the application will be described below in conjunction with the drawings in the embodiment of the application. Obviously, the described embodiment is only a part of the application Examples, but not all examples. Based on the embodiments in this application, all should belong to the protection scope of this application.

At present, 5G standard R15 and R16 versions have been launched one after another, and research and development products have also been launched one after another. The support of 5G standards for different services (such as enhanced mobile broadband (Enhanced Mobile Broadband, eMBB), ultra-reliable and low-latency communications (Ultra-reliable and Low Latency Communications) , URLLC), and Massive Machine Type Communication (MassiveMachine Type Communication, mMTC)) make it extremely flexible, permeable and motivating, thus deeply integrating with all walks of life and providing key technical support for social development. Not only the civilian field has a strong demand for 5G, but the demand for 5G in military, emergency and other special fields is also increasingly prominent. However, all current versions of the standards are used in commercial environments. The deployment scenarios under consideration must have dedicated spectrum resources, and there must be no interference from different systems and malicious interference during use. Neither considers deployment in jamming environments. However, in the field of private networks, due to limited spectrum resources and weak supervision, interference is inevitable even in wireless countermeasure environments, and the demand for 5G in the field of private networks is also increasingly prominent, so it is necessary to improve 5G anti-interference capabilities to meet private network requirements.

FIG. 1 is a schematic diagram of a 5G carrier grid and synchronization grid. However, 5G uses a sparse synchronization grid as shown in Figure 1, which makes it easier to be interfered. At present, the 5G system has certain flexibility in frequency domain resource scheduling. Through frequency selective scheduling, subcarriers with poor channel conditions can be avoided, but this method can only be used for interference avoidance of shared channels. 5G can also use carrier aggregation technology to avoid interference by activating/deactivating different carriers, but this method needs to be implemented after the terminal device establishes a connection. 5G also introduces the Bandwidth Part (BWP), which can flexibly allocate time-frequency resources and avoid interference, but this method has the same disadvantages as the carrier aggregation method. In addition, supplementary anti-jamming links can be introduced to assist 5G in anti-jamming, but it is difficult to realize that the standards need to be revised jointly by the base station and the terminal equipment side. The 5G system can also use multiple synchronous signals concurrently to provide diversity gain, but it also needs to be modified on both the base station and terminal equipment side to achieve it, which has extremely high requirements on the industry chain and cannot be applied quickly and efficiently.

Due to the relatively low degree of independent control of terminal equipment chips in my country, it is difficult to modify the baseband and protocol of terminal equipment. In comparison, base stations have many platforms that support independent research and development by manufacturers, and can be flexibly modified. Therefore, only by innovating the anti-interference enhancement of the 5G system from the perspective of the base station can it be applied more quickly and efficiently.

This application proposes a base station anti-jamming method. Under the premise of not modifying the standard operation of the terminal equipment, the synchronization signal and the physical broadcast channel (Physical Broadcast Channel, PBCH) block (Synchronization Signal and PBCH block, SSB) and Control resource set (CORESET) #0 is enhanced, combined with reserved resource configuration cleverly, so that network equipment can obtain the ability to resist narrowband heterogeneous system interference, and can communicate with terminal equipment, improving the practicability of the anti-interference method.

The following is a further description of the technical solution of the present application in the form of an embodiment. As shown in FIG. 2, it is a schematic diagram of an embodiment of the communication anti-interference method in the embodiment of the present application, which may include:

Optionally, the obtaining the first interference information by the network device may include: the network device obtaining the first interference information by using first interference measurement information, where the first interference measurement information is obtained through measurement by the network device, or by a terminal The device is reported or obtained from a third party.

Exemplarily, the network device uses a base station as an example for illustration. The base station obtains interference information through interference measurement, which is used for subsequent determination of primary and secondary synchronization frequency points, that is, used to indicate the time-frequency resource positions of SSB and CORESET#0. Optionally, the interference measurement information may be actively measured by the base station, or the base station may instruct the terminal equipment to measure and report, or a third party may input the interference measurement.

202. The network device selects N available first synchronization frequency points according to the first interference information, where N is an integer greater than 1, and the N available first synchronization frequency points include a primary synchronization frequency point and N- 1 secondary sync frequency point.

Optionally, the interference values of the N available first synchronization frequency points are lower than a first threshold.

Exemplarily, the base station selects N available synchronization frequency points according to the first interference information, and the interference values at these synchronization frequency points are lower than a certain threshold (the threshold can be set or adjusted according to actual conditions). If the number of synchronization frequency points whose interference value is lower than a certain threshold is not enough, if it is X, then the synchronization frequency points lower than the certain threshold are arranged in ascending order according to the difference in interference value, and the previous one with a lower interference value is selected. Y synchronization frequency points, where X+Y=N. Among the N synchronization frequency points, one of the frequency points is selected as the primary synchronization frequency point, and the others are secondary synchronization frequency points, which may also be called secondary synchronization frequency points.

203. The network device configures a corresponding main message and system message for each first synchronization frequency point.

It can be understood that the corresponding main message and system message are configured for the SSB and CORESET#0 of each first synchronization frequency point.

The main message can be the master message block (Master Information Block, MIB); the system message can be the system message block (System Information Block, SIB), or the remaining minimum system message (RemainingMinimumSystem Information, RMSI).

204. The network device broadcasts the main message and the system message corresponding to each first synchronization frequency point.

The embodiment of the present application provides N first synchronous frequency points, which can be used by terminal devices to perform network access operations. This application can provide multiple synchronous frequency points for the terminal equipment for the terminal equipment to perform network access operations, because each synchronous frequency point has a corresponding main message and system message, after the terminal equipment accesses a certain synchronous frequency point, it can be in Signals are sent and received on the corresponding main message and system message to avoid interference and improve the anti-interference capability of the system. Furthermore, because the network device provides multiple synchronization frequency points for the terminal device, when the terminal device cannot access the primary synchronization frequency point, it can access the secondary synchronization frequency point, which improves the probability that the terminal device can access the network.

305. The terminal device performs network access according to the main message and system message corresponding to each first synchronization frequency point.

307. When the second interference information exceeds a preset range, select N available second synchronization frequency points according to the second interference information.

Judging whether the second interference information is within the preset range, if it is within the preset range, it means that the second interference information will not be affected by the interference on the communication of the subsequent synchronization frequency point; if it is not within the preset range, it means that the second interference information has no effect on Communications on synchronous frequency points are affected by interference.

308. For each second synchronization frequency point, configure corresponding main messages and system messages.

It can be understood that the corresponding main message and system message are configured for the SSB and CORESET#0 of each second synchronization frequency point.

The terminal device receives the main message and the system message corresponding to each first synchronization frequency point broadcast by the network device.

In the embodiment of the present application, the configuration of the synchronous frequency point can be modified according to the updated interference information to increase the probability of terminal equipment accessing the network and prevent the existence of new interference information from causing interference to the previously configured synchronous frequency point, so that the terminal equipment Unable to connect to the network, and thus unable to communicate. When the second interference information exceeds the preset range, N available second synchronization frequency points can be selected, and corresponding main messages and system messages can be configured for the N second synchronization frequency points, such as modifying the N second synchronization frequency points The SSB of the point and the transmission content of CORESET#0. That is, the main message and the system message corresponding to the N second synchronization frequency points are modified.

Mode 2: The network device sends the first main message and first indication information through the SSB time-frequency resource position of the primary synchronization frequency point, and the first indication information is used to indicate the first control resource set of the primary synchronization frequency point Time-frequency resource location, where the first system message is sent at the time-frequency resource location of the first control resource set; the first main message, the first indication information, and the first system message are used by the terminal device to perform Network access; the network device sends the second main message and the third indication information through the SSB time-frequency resource positions of the N-1 secondary synchronization frequency points, and the third indication information is used to indicate the N-1 secondary synchronization frequency The time-frequency resource position of the second control resource set of the point, and the second system message is sent at the time-frequency resource position of the second control resource set; the second main message, the third indication information and the second system message Used for the terminal device to access the network.

It should be noted that at the primary synchronization frequency point, the MIB message and the first indication information are sent at the corresponding SSB time-frequency resource position according to the method stipulated in the protocol. The first indication information is used to indicate the CORESET#0 corresponding to the primary synchronization frequency point. Time-frequency resource location, send a System Information Block (SIB) or Remaining Minimum System Information (RMSI) in CORESET#0 to guide the terminal device to complete the subsequent network access process.

Send the MIB message and the second indication information at the SSB time-frequency resource position corresponding to the secondary synchronization frequency point. The second indication information is used to carry information bits pointing to the CORESET#0 time-frequency resource position of the primary synchronization frequency point. The CORESET#0 time-frequency resource location corresponding to the frequency point does not send a message to guide the terminal device to complete the subsequent network access process; or,

Send the MIB message and the third indication information at the SSB time-frequency resource position corresponding to the secondary synchronization frequency point, the third indication information is used to indicate the CORESET#0 time-frequency resource position corresponding to the secondary synchronization frequency point, and send it in CORESET#0 The system information block SIB, or the remaining minimum system information RMSI, guides the terminal device to complete the subsequent network access process.

405. The terminal device performs network access according to the main message and system message corresponding to each first synchronization frequency point.

407. The network device sends the three-dimensional bitmap to the target terminal device, where the three-dimensional bitmap is used by the target terminal device to perform data transmission and reception on the time-frequency resource corresponding to the accessed synchronization frequency point.

The terminal device receives the three-dimensional bitmap sent by the network device.

Optionally, the network device sends the 3D bitmap to the target terminal device through RRC signaling.

It can be understood that the network device configures a three-dimensional bitmap (bitmap) indicating reserved resources, respectively indicating a resource block (Resource Block, RB) number, a time slot number and a symbol number of the reserved resources.

A resource block includes each time slot, and each time slot includes each symbol. These reserved resources shall include all SSBs of the primary and secondary synchronization frequency points and the time-frequency resources occupied by CORESET#0. Through RadioResource Control (RRC) signaling, the three-dimensional bitmap (bitmap) information of the reserved resources is sent to the terminal device, instructing the terminal device to perform data transmission and reception at the SSB of the primary synchronization frequency point and CORESET#0, and in the secondary The SSB of the synchronization frequency point and CORESET#0 do not transmit and receive data; optionally, when the terminal device accesses the network through the secondary synchronization frequency point, instruct the terminal device to perform data transmission and reception at the SSB of the secondary frequency point and CORESET#0.

408. The terminal device performs data transmission and reception on the time-frequency resource corresponding to the accessed synchronization frequency point according to the three-dimensional bitmap.

It can be understood that the synchronization frequency point accessed by the terminal device may be a primary synchronization frequency point or a secondary synchronization frequency point. If the terminal device accesses the primary synchronization frequency point, data may be sent and received on the time-frequency resource corresponding to the accessed primary synchronization frequency point. If the terminal device accesses one of the secondary synchronization frequency points, data can be sent and received on the time-frequency resource corresponding to the accessed secondary synchronization frequency point.

As shown in FIG. 5 , it is a schematic diagram of time-frequency resources, SSB, and CORESET#0 in the embodiment of the present application. In the embodiment of the present application, the time-frequency resource position of the master-slave synchronization frequency point is determined by analyzing the interference information; the SSB at the master synchronization frequency point sends a master information block (Master Information Block, MIB) message, indicating the CORESET at the master synchronization frequency point #0 position, and send the remaining minimum system message RMSI message or SIB message at CORESET#0 of the main synchronization frequency point. The MIB message is sent at the SSB of the secondary synchronization frequency point to indicate the position of CORESET#0 of the primary synchronization frequency point, and the CORESET#0 of the secondary synchronization frequency point is left blank for no data transmission and reception. The three-dimensional bitmap (bitmap) indicates that the terminal equipment does not perform data transmission and reception at the SSB of the secondary synchronization frequency point and CORESET#0, so as to avoid the interference caused by the modification of this solution to the data transmission and reception of the terminal equipment.

In the embodiment of the present application, the first interference information is obtained; according to the first interference information, N available first synchronization frequency points are selected, N is an integer greater than 1, and the N available first synchronization frequency points Including one primary synchronization frequency point and N-1 secondary synchronization frequency points; for each first synchronization frequency point, configure the corresponding main message and system message; broadcast the main message and system message corresponding to each first synchronization frequency point information. Compared with the prior art where there is only one synchronization frequency point for terminal equipment to access, the embodiment of the present application provides N first synchronization frequency points for terminal equipment to perform network access operations.
