Detailed Description

In order for those skilled in the art to better understand the present application, the following description will describe embodiments of the present application with reference to the accompanying drawings, and it is apparent that the described embodiments are only some embodiments of the present application, not all embodiments. Based on the examples in this application, all shall fall within the scope of protection of this application.

The current versions of the 5G standard R15 and R16 are successively landed, developed products are also successively introduced, and the support of the 5G standard on different services (such as enhanced mobile broadband (Enhanced Mobile Broadband, eMBB), high-reliability and low-delay communication (Ultra-reliable and Low Latency Communications, URLLC) and large-scale machine type communication (Massive Machine Type Communication, mMTC)) enables the system to have extremely strong flexibility, permeability and portability, so that the system is deeply fused with various industries, and provides key technical support for social development. Not only is the civil field with stronger requirements for 5G, but also the requirements for 5G in the special fields of military, emergency and the like are increasingly prominent. However, all the current standards are used in commercial environments, the deployment scenario considered needs to have special spectrum resources, when the deployment scenario is used, no different system interference and malicious interference exist, the deployment scenario needs to have special spectrum, and no different system interference and malicious interference are not considered. However, in the private network field, because of limited spectrum resources and weak supervision, even when the wireless network is used in a wireless countermeasure environment, interference inevitably exists, and the requirement of the private network field on 5G is increasingly prominent, so that the anti-interference capability of the 5G needs to be improved to meet the requirement of the private network.

Fig. 1 is a schematic diagram of a 5G carrier grid and a synchronization grid. Whereas 5G employs a sparse synchronization grid as shown in fig. 1, and is thus more susceptible to interference. At present, the 5G system has certain flexibility in the aspect of frequency domain resource scheduling, and can avoid subcarriers with poor channel conditions through frequency selective scheduling, but the method can only be used for interference avoidance of a shared channel. The 5G may also employ carrier aggregation techniques to avoid interference by activating/deactivating different carriers, but this method needs to be implemented after the terminal device establishes a connection. 5G further introduces a wideband Part (BWP), which may add flexible allocation of time-frequency resources to avoid interference, but this method has the same drawbacks as the carrier aggregation method. In addition, a supplementary anti-interference link can be introduced to assist the 5G in anti-interference, but the standard is required to be modified together at the base station and the terminal equipment side, so that the implementation difficulty is high. The 5G system can also provide diversity gain by adopting a mode of concurrency of multipath synchronous signals, but the system can be realized by modifying both the base station side and the terminal equipment side, has extremely high requirements on an industrial chain and cannot be applied quickly and efficiently.

At present, the autonomous controllable degree of the terminal equipment chip is relatively low in China, and the realization difficulty of modifying the baseband and the protocol of the terminal equipment is high. In comparison, the base station has a plurality of platforms for supporting independent research and development of manufacturers and can be flexibly modified. Therefore, the anti-interference enhancement of the 5G system is innovated from the base station perspective, so that the 5G system can be applied to the floor more quickly and efficiently.

The application provides a base station anti-interference method, which is characterized in that on the premise of not modifying the standard operation of terminal equipment, a network device is used for enhancing a synchronous signal and a physical broadcast channel (Physical Broadcast Channel, PBCH) block (Synchronization Signal and PBCH block, SSB) and a control resource set (CORESET) #0, and the reserved resource configuration is skillfully combined, so that the network device can obtain the anti-narrowband heterogeneous system interference capability, and can be interconnected and intercommunicated with the terminal equipment, thereby improving the practicability of the anti-interference method.

For example, the network device uses a base station as an example, and the base station obtains interference information through interference measurement, and the interference information is used for subsequently determining primary and secondary synchronization frequency points, namely, is used for indicating the time-frequency resource positions of the SSB and the CORESET#0. Optionally, the interference measurement information may be actively measured by the base station, or the base station instructs the terminal device to measure and report the interference measurement information, or a third party inputs the interference measurement information.

If the number of the synchronous frequency points with the interference value lower than the certain threshold is insufficient, if the number of the synchronous frequency points is X, the synchronous frequency points with the interference value lower than the certain threshold are arranged in an ascending order according to the difference of the interference values, and the first Y synchronous frequency points with the lower interference value are selected, wherein X+Y=N. One of the N synchronous frequency points is selected as a main synchronous frequency point, and the other frequency points are auxiliary synchronous frequency points, which can also be called auxiliary synchronous frequency points.

The embodiment of the application provides N first synchronous frequency points which can be used for network access operation of terminal equipment. According to the method and the device, a plurality of synchronous frequency points can be provided for the terminal equipment, so that the terminal equipment can perform network access operation, and because each synchronous frequency point is provided with the corresponding main message and the corresponding system message, after the terminal equipment is accessed to a certain synchronous frequency point, the terminal equipment can receive and send signals on the corresponding main message and the corresponding system message, interference is avoided, and the anti-interference capability of the system is improved. Furthermore, because the network device provides a plurality of synchronization frequency points for the terminal device, the auxiliary synchronization frequency points can be accessed under the condition that the terminal device cannot access the main synchronization frequency points, and the probability that the terminal device can access the network is improved.

And under the condition that the second interference information exceeds the preset range, N available second synchronous frequency points can be selected, and corresponding main messages and system messages are configured for the N second synchronous frequency points, for example, the transmission contents of SSB and CORESET#0 of the N second synchronous frequency points are modified. Namely, the main message and the system message corresponding to the N second synchronous frequency points are modified.

If the terminal equipment is accessed to one of the auxiliary synchronous frequency points, data can be received and transmitted on the time-frequency resource corresponding to the accessed auxiliary synchronous frequency point.

Fig. 5 is a schematic diagram of time-frequency resources and SSB, coreset#0 in the embodiment of the application. According to the embodiment of the application, the time-frequency resource positions of the main and auxiliary synchronous frequency points are determined through analysis of the interference information; the SSB at the master synchronization frequency sends a master message block (Master Information Block, MIB) message indicating the CORESET #0 position at the master synchronization frequency and sends the remaining minimum system message RMSI message or SIB message at CORESET #0 at the master synchronization frequency. And transmitting MIB information at SSB of the secondary synchronization frequency point, indicating the CORESET#0 position of the primary synchronization frequency point, and leaving the CORESET#0 of the secondary synchronization frequency point blank to not transmit and receive data. The three-dimensional bit map (bitmap) indicates that the terminal equipment does not receive and transmit data between the SSB and the CORESET #0 of the auxiliary synchronous frequency point, so that the interference caused by the modification of the scheme on the data receiving and transmitting of the terminal equipment is avoided.

In the embodiment of the application, first interference information is acquired; 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 comprise a main synchronization frequency point and N-1 auxiliary synchronization frequency points; configuring a corresponding main message and a corresponding system message for each first synchronous frequency point; and broadcasting the main message and the system message corresponding to each first synchronous frequency point. Compared with the prior art that only one synchronization frequency point is used for accessing the terminal equipment, the embodiment of the application provides N first synchronization frequency points which can be used for the terminal equipment to access the network. According to the method and the device, a plurality of synchronous frequency points can be provided for the terminal equipment, so that the terminal equipment can perform network access operation, and because each synchronous frequency point is provided with the corresponding main message and the corresponding system message, after the terminal equipment is accessed to a certain synchronous frequency point, the terminal equipment can receive and send signals on the corresponding main message and the corresponding system message, interference is avoided, and the anti-interference capability of the system is improved. The main message and the system message sent by the synchronous frequency point are necessary information for guiding the terminal equipment to discover and access the network equipment, and if the main message and the system message cannot be successfully received and decoded, the terminal equipment cannot access the network and communicate.

The following describes the components of the mobile phone in detail with reference to fig. 9:

the RF circuit 910 may be used for receiving and transmitting signals during a message or a call, and particularly, after receiving downlink information of a base station, the signal is processed by the processor 980; in addition, the data of the design uplink is sent to the base station. Typically, the RF circuitry 910 includes, but is not limited to, an antenna, at least one amplifier, a transceiver, a coupler, a low noise amplifier (Low Noise Amplifier, LNA), a duplexer, and the like. In addition, the RF circuitry 910 may also communicate with networks and other devices via wireless communications.

Alternatively, the touch panel 931 may include two parts of a touch detection device and a touch controller. The touch detection device detects the touch azimuth of a user, detects a signal brought by touch operation and transmits the signal to the touch controller; the touch controller receives touch information from the touch detection device and converts it into touch point coordinates, which are then sent to the processor 980, and can receive commands from the processor 980 and execute them. In addition, the touch panel 931 may be implemented in various types such as resistive, capacitive, infrared, and surface acoustic wave. The input unit 930 may include other input devices 932 in addition to the touch panel 931.

Further, the touch panel 931 may overlay the display panel 941, and when the touch panel 931 detects a touch operation thereon or thereabout, the touch operation is transferred to the processor 980 to determine a type of touch event, and then the processor 980 provides a corresponding visual output on the display panel 941 according to the type of touch event. Although in fig. 9, the touch panel 931 and the display panel 941 are implemented as two separate components for the input and output functions of the mobile phone, in some embodiments, the touch panel 931 may be integrated with the display panel 941 to implement the input and output functions of the mobile phone.

Wi-Fi belongs to a short-distance wireless transmission technology, and a mobile phone can help a user to send and receive e-mails, browse webpages, access streaming media and the like through a Wi-Fi module 970, so that wireless broadband Internet access is provided for the user. Although fig. 9 shows Wi-Fi module 970, it is understood that it does not belong to the necessary constitution of the handset, and can be omitted entirely as needed within the scope of not changing the essence of the invention.

The processor 980 is a control center of the handset, connecting various parts of the entire handset using various interfaces and lines, performing various functions and processing data of the handset by running or executing software programs and/or modules stored in the memory 920, and invoking data stored in the memory 920, thereby performing overall monitoring of the handset.
