Fig. 1 schematically shows a flowchart of an interference management method for a heterogeneous wireless networking according to an embodiment of the present application, where the heterogeneous wireless networking includes a control base station providing a data service in a first frequency band, and a data base station providing a data service in a second frequency band, where the second frequency band is higher than the first frequency band. As shown in fig. 1, the method includes:

s101, when a first wireless terminal detects that a first accessed data base station cannot provide data service, an access request is sent to a control base station in heterogeneous wireless networking.

And S102, after the control base station is accessed to the first wireless terminal, sending a control signaling to a second data base station, wherein the control signaling is used for instructing the second data base station to train a currently deployed interference management model to obtain model parameters, and the second data base station is a data base station which can provide data service in the heterogeneous wireless networking.

And S103, the second data base station aggregates the trained model parameters to obtain aggregate model parameters, updates the interference management model by using the aggregate model parameters, and then performs interference management on the heterogeneous wireless network according to the updated interference management model.

In the related technology, high-low frequency heterogeneous wireless networking based on separation of a control base station and a data base station can improve the area coverage capability and greatly improve the overall spectrum efficiency of the system, seamless high-speed experience is provided for access users, and the method is a networking mode mainly considered by a 6 th generation mobile communication system (6G).

The high-frequency and low-frequency heterogeneous wireless networking mainly utilizes a control base station to realize basic coverage in the whole area through a low-frequency band. And the data base station is used for bearing hot spot coverage and high-speed transmission through a high-frequency band, so that the requirements of a future 6G network on higher data flow, higher user experience rate, massive terminal connection and lower time delay are met, meanwhile, the data base station only has the functions of an RLC (radio link control), an MAC (media access control) layer and a physical layer, the deployment cost of an operator can be obviously reduced, when the data base station detects that the number of users in certain time periods is less, a part of the data base station is properly closed on the premise of ensuring the service quality of the users to realize cell dynamic switching, the energy consumption can be reduced, and the requirement of 6G for developing green communication is met.

However, there are still many difficulties in implementing high and low frequency heterogeneous wireless networking. Firstly, the dense deployment of the multi-layer nodes needs to consider the compromise between the backhaul method and the deployment cost, secondly, the dense deployment of the low-power data base station brings the problem of strong interference, and meanwhile, the switching of the data base station causes network interference fluctuation, so that the dynamic switching of the data base station cell has a coupling relation with the interference effect, and further, the user rate is influenced.

However, in the heterogeneous multi-layer network, since the radio environment is highly dynamic, the conventional interference coordination technology first collects instantaneous global Channel State Information (CSI) and then calculates a sub-optimal solution, however, it is challenging to collect instantaneous global CSI in the heterogeneous multi-layer network, the global CSI usually changes rapidly, the output solution is usually outdated or invalid, efficient interference coordination cannot be provided, and in the system of the high-frequency and low-frequency wireless cooperative networking, the data set station dynamic switch increases the dimensionality of the intra-system interference dynamic change action.

Therefore, how to design a high-frequency and low-frequency heterogeneous wireless networking architecture capable of adapting to a 6G system and propose that an efficient and dynamic interference coordination mechanism under the architecture is a problem to be researched to ensure the performance of the high-frequency and low-frequency heterogeneous wireless networking.

In view of the above problems, the present invention provides a method for providing data service for a lost terminal by a control base station when detecting that a part of data base stations close service due to network environment deterioration in a heterogeneous wireless network. And the control base station instructs the target data base station to train again according to the current network environment to obtain new model parameters and aggregate the new model parameters so as to update the interference management model deployed on each data base station according to the re-aggregated updated model parameters.

Specifically, fig. 2 is a diagram of a heterogeneous wireless networking proposed in the present application, where the networking includes a plurality of data base stations for communication and a plurality of control base stations.

In one way, under the service range covered by the control base station, the user may drive the control base station to provide the service related to the control and data information in the low frequency band (i.e. the first frequency band). Under the service range covered by the data set station, the user can drive the data base station to provide the service related to the data information in the high frequency period (i.e. the second frequency band).

In one mode, the data base stations can be densely deployed in an area with a large user access and a large traffic demand to support seamless high-speed experience of users. In another mode, the data base stations with close geographic distances and overlapping coverage areas can be divided into the same heterogeneous wireless networking, and heterogeneous wireless networking centralized control is performed on the data base stations.

In one mode, the method can select one data base station from the multiple data base stations as a target data base station, so that the target data base station performs centralized backhaul link communication with the control base station, and other data base stations in the heterogeneous wireless network do not need to establish backhaul link connection with the control base station any more, and directly establish backhaul links with the target data base station in the heterogeneous wireless network to complete backhaul communication. Therefore, the purposes of reducing the burden of a backhaul link of a control base station and reducing signaling overhead are achieved.

In addition, in the heterogeneous wireless networking provided by the application, each data base station in the heterogeneous wireless networking can perform cooperation processing through shared data, channel State Information (CSI), scheduling information and Precoding Matrix Index (PMI) information, so as to improve the performance of cell edge users.

In one mode, the target data base station has strong calculation and storage capacity, and data and channel state information in the data cells in the heterogeneous wireless network are uniformly positioned, so that interference coordination among the cells can be easily realized by controlling the heterogeneous wireless network of the adjacent data base stations, and the requirement of high experience rate of users in a hotspot area can be met.

The high-low frequency heterogeneous wireless networking can adopt a return trip mode of a wireless link, wireless return trip is combined with a millimeter wave large-scale MIMO beam forming technology to provide huge antenna gain for the wireless return trip link, and relatively high path loss caused by rainfall and air absorption can be effectively resisted.

However, in an ultra-dense networking environment, as the deployment number of the data base stations is increased, the distance between the data base stations in a limited space is closer and closer, and the problem of same-layer interference is more and more serious. Therefore, for the above proposed high and low frequency cooperative networking architecture, the interference management method proposed in the present application only considers the same layer interference between the data base station and the wireless terminal served by the data base station.

Further, referring to fig. 3, the following describes specifically an interference management method for heterogeneous wireless networking, provided by the present application:

step 1, when a first data base station in the heterogeneous wireless networking detects that the flow of a served area is lower than a base station starting threshold, the first data base station is automatically closed.

And step 2, when the first wireless terminal UE detects that the accessed first data base station can not provide data service, the first wireless terminal UE sends a PUSCH reference signal through a control channel and sends an access request to the control base station.

And 3, controlling the base station to distribute the sub-carriers to the first UE which sends the message, allowing the UE to access and providing data service for the first UE.

And 4, the control base station sends a PDCCH control signaling to the target data base station through a wireless backhaul, and replans the wireless terminal access in the heterogeneous wireless networking.

And step 5, the target data base station forwards the control signaling of the control base station to other data base stations in the heterogeneous wireless networking.

The target data base station may be any number of data base stations in the second data base station. In one approach, it may be an idle data base station, or a data base station with higher computing performance for the device.

And 6, collecting interference measurement reports reported by the second wireless terminal accessed by other data base stations.

And 7, training the self-deployed interference management model by using the acquired interference measurement report by other data base stations to obtain initial model parameters, and uploading the self-deployed interference management model parameters to the target data base station.

And 8, the target data base station re-aggregates the model parameters reported by other data base stations to obtain aggregated model parameters. And the aggregated aggregation model parameters are sent to other data base stations in the heterogeneous wireless network.

And 9, the second data base station updates the model of the self-deployed interference management model by using the aggregation model parameters to obtain an updated interference management model.

And step 10, the second data base station performs interference management on the heterogeneous wireless network based on the updated interference management model.

Wherein the interference management may include at least one of traffic management, resource allocation management, and channel power allocation management.

Optionally, in another embodiment based on the foregoing method of the present application, after the controlling base station accesses the first wireless terminal, sending a control signaling to the second data base station, where the sending includes:

the other data base stations collect interference measurement reports reported by second wireless terminals accessed with the other data base stations, and train self-deployed interference management models by using the interference measurement reports to obtain initial model parameters;

and the target data base station transmits the aggregation model parameters to other data base stations.

Optionally, in another embodiment based on the foregoing method of the present application, performing interference management on the heterogeneous wireless network according to the updated interference management model includes:

Optionally, in another embodiment based on the foregoing method of the present application, in the heterogeneous wireless networking, when the data base station detects that traffic is lower than a preset threshold, the data base station stops providing data service to the wireless terminal.

As shown in fig. 4, the present application further illustrates the scheme:

step 1: each UE in the heterogeneous wireless network continuously receives a measurement physical signal which is sent by the data base station and is used for measuring the network condition with the data base station.

In one mode, the UE may first receive downlink signals (for example, downlink physical signals) transmitted by a plurality of data base stations including an interfering data base station, and detect a downlink signal from which interference energy transmitted by the interfering data base station is too high based on interference energy of each downlink signal, and use the downlink signal as the interfering signal.

And 2, the UE acquires a measured physical signal and a corresponding configuration parameter which are sent by the interference data base station and between the UE and the interference data base station.

Wherein, for the configuration parameter, it may include one or more of the following:

measuring the transmission period of the physical signal, measuring the time domain initial position offset in the period of the physical signal, measuring the repetition times/single transmission duration in the period of the physical signal, measuring the transmission frequency/bandwidth of the physical signal, synchronizing signal block subcarrier offset, measuring the subcarrier interval of the physical signal, measuring the sequence of the physical signal, and measuring the frequency interval of the physical signal interval with certain frequency transmission.

In one mode, the method for the UE to obtain the configuration parameter of the interfering base station sending the UE and measuring the physical signal between the UE and the base station may be that the UE obtains the configuration parameter by receiving a user-specific signaling or a system message sent by the interfering base station. And extracting the configuration parameters of the measurement physical signals between the UE and the base station, which are sent by the interference base station and carried in the configuration parameters, through the user-specific signaling or the system message. It can be understood that the purpose of the UE to obtain the configuration parameters is to more efficiently receive the physical signals measured between the UE and the base station.

In another mode, the UE receives a UE and inter-base station measurement physical signal sent by an interfering base station. For example, the measurement physical signal may be a downlink physical signal in an interfering cell, such as a synchronization signal block, a channel state information reference signal, and the like, or may be a dedicated UE and inter-base station measurement physical signal transmitted by an interfering base station.

Further, the measured physical signal between the UE and the base station may be a time domain periodic signal. As an example, the UE and the base station may measure the physical signal and transmit the measured physical signal at a certain period, and repeatedly transmit multiple copies (e.g., at least two copies) of the measured physical signal in the same transmission period, where the multiple copies in the same period have different copy index values.

Further, an example of the periodic inter-base station measurement physical signal may be a synchronization signal block sent by an interfering base station in downlink, including, for example, a downlink primary synchronization signal, a downlink secondary synchronization signal, and a demodulation reference signal of a physical broadcast channel.

Furthermore, the UE needs to measure the interference signal energy between the interfering base station and the UE with the same transmission period and the same frequency subband but with different replica indexes in the multiple measured physical signals, so as to obtain the interference signal strength between the base station and the UE for each replica index. And taking the replica indexes of the M replicas with the interference signal strength greater than a preset threshold value and the interference signal strength as interference measurement results, and generating an interference measurement report based on the interference measurement results.

In one approach, M is a positive integer, and M < = X,

wherein, X is a positive integer, is predetermined by the system, and represents the maximum number of downlink beams transmitted by the base station in the same frequency sub-band.

And step 3: and the UE reports the interference measurement report, and the reported object is a data base station providing data service for the UE.

Further, the UE may report the interference measurement result by reporting the interference measurement report to the data base station through an uplink.

In one approach, the UE reports interference measurement results on semi-persistent scheduling physical resources configured to the UE by the data base station. By this way, the UE can report the interference measurement result to the data base station timely and rapidly.

And 4, step 4: each data base station is deployed with a DRL-based agent, and the base station can therefore be regarded as an intelligent agent, and each agent performs model training according to data input of a measurement report and an initial interference management model.

And 5: optionally, if the data base station is in the heterogeneous wireless networking of the data base station, in order to ensure the coordination of interference of the data base station in the heterogeneous wireless networking, and avoid the situation that the data base station blindly pursues high transmission power to affect the performance of the whole heterogeneous wireless networking in order to improve throughput, the data base station uploads the model parameters of the trained interference management model to the target data base station.

And 6: optionally, the target data base station performs aggregation of the model parameters to obtain global model parameters of the interference management model in the heterogeneous wireless network.

And 7: optionally, the target data base station issues the aggregated global model parameter to each data base station in the heterogeneous wireless network.

And 8: and each data base station updates the model of the self-deployed interference management model by using the global model parameters to obtain an updated interference management model.

In one manner, the data base station in the present application can make an interference coordination decision for base station power control according to the updated interference management model to maximize the throughput of the wireless network system.

And step 9: and the data base station detects that the flow of the served area is lower than the base station starting threshold value and automatically closes the data base station.

Step 10: and when the UE detects that the accessed first data base station cannot provide data service, the UE sends a PUSCH reference signal to a control base station through a control channel and sends an access request.

Step 11: and controlling the base station to distribute the sub-carriers to the UE sending the message, allowing the UE to access and providing data service for the UE.

Step 12: and the control base station sends a PDCCH control signaling to the target data base station through a wireless backhaul, and replans the user access.

Step 13: the target data base station forwards the control signaling of the control base station to each data base station in the heterogeneous wireless network.

Step 14: the data base station which is still started collects the real-time information in the network environment and updates the interference management model.

The information collected again by the data base station comprises the new access relation between the UE and the data base station and an interference measurement report reported by the UE corresponding to the new access relation.

Step 15: and as part of the data base stations are closed, the intelligent agents on the base stations are inactivated, and the target data base station re-aggregates the data base station model parameters.

Step 16: and the target data base station transmits the aggregated interference management model parameters to the data base station in the heterogeneous wireless network.

It can be understood that, since the network environment of the heterogeneous wireless network changes, the target data base station is required to train to obtain new model parameters according to the current network environment again and to aggregate the new model parameters, so that the interference management model deployed on each data base station is updated according to the re-aggregated model parameters. Therefore, the purpose of accurately managing the interference of each device in the group network is achieved.

And step 17: and the data base station performs autonomous interference coordination decision according to the new interference management model.

It can be understood that by adopting the architecture and the configuration method of the present application, inter-cell interference in a highly dynamic system in which a base station and a data base station are separated can be coordinated and controlled in an intelligent manner, and meanwhile, the throughput of a dense multi-layer heterogeneous RAN system is effectively improved.

By applying the technical scheme of the application, when the situation that a part of data base stations close service due to the fact that the network environment is deteriorated in the heterogeneous wireless networking is detected, the control base station provides data service for the lost terminal. And the control base station instructs the target data base station to train the currently deployed interference management model to obtain new model parameters and then to aggregate the new model parameters, so that the interference management model deployed on each data base station is updated according to the re-aggregated updated model parameters. And further, in the heterogeneous wireless networking, the data base station can acquire the latest interference management model matched with the current network environment in real time to perform interference management on each device in the wireless networking.

Optionally, in another embodiment of the present application, as shown in fig. 5, an interference management apparatus for heterogeneous wireless networking is further provided. The heterogeneous wireless networking comprises a control base station providing data service in a first frequency band and a data base station providing data service in a second frequency band, wherein the second frequency band is higher than the first frequency band, and the heterogeneous wireless networking comprises the following steps:

the management module 203 is configured to aggregate the trained model parameters by the second data base station to obtain aggregate model parameters, update an interference management model by using the aggregate model parameters, and perform interference management on the heterogeneous wireless network according to the updated interference management model.

In another embodiment of the present application, the sending module 202 is configured to perform the steps of:

in the heterogeneous wireless networking, when the data base station detects that the flow is lower than a preset threshold value, the data base station stops providing data service for the wireless terminal.
