Description

Technical Field

[0001] This application relates to wireless communication processing technology, and in particular to an interference management method, apparatus, electronic device and medium for heterogeneous wireless networking. Background Technology

[0002] Heterogeneous, multi-layered, and full-band-accessible high- and low-frequency wireless cooperative networking is an inevitable trend in future 6G network architecture. Low-frequency bands primarily address coverage issues, while high-frequency bands are mainly used to improve system capacity in high-traffic areas.

[0003] However, to adapt to the architecture of 6G wireless cooperative networking and reduce the additional overhead of centralized intelligent interference management schemes, interference coordination mechanisms for 6G should possess distributed intelligence characteristics. This also means that enhancing the anti-interference capability of one or a few cells is far from sufficient; it is necessary to enhance the interference coordination and processing capabilities between cells. Therefore, how to design an interference management method under heterogeneous wireless networking has become a problem that needs to be solved by those skilled in the art. Summary of the Invention

[0014] The other data base stations collect interference measurement reports reported by the second wireless terminals connected to them, and use the interference measurement reports to train their own deployed interference management models to obtain initial model parameters.

[0015] The other data base stations each upload their own initial model parameters to the target data base station, so that the target data base station can collect multiple initial model parameters in the current heterogeneous wireless network.

[0022] Optionally, in another embodiment based on the method described above, after the first wireless terminal sends an access request to the control base station in the heterogeneous wireless network when it detects that the first data base station cannot provide data service, the method further includes:

[0023] The control base station allocates a subcarrier to the first wireless terminal so that the first wireless terminal can access the control base station using the subcarrier.

[0024] Optionally, in another embodiment based on the method described above in this application, in the heterogeneous wireless network, when the data base station detects that the traffic is lower than a preset threshold, it stops providing data services to the first wireless terminal.

[0025] According to another aspect of the embodiments of this application, an interference management device for a heterogeneous wireless network is provided. The heterogeneous wireless network includes a control base station providing data services in a first frequency band and a data base station providing data services in a second frequency band, wherein the second frequency band is higher than the first frequency band.

[0026] The detection module is configured to send an access request to the control base station in the heterogeneous wireless network when the first wireless terminal detects that the first data base station it accesses cannot provide data services.

[0027] The transmitting module is configured to send control signaling to the second data base station after the control base station accesses the first wireless terminal. The control signaling is used to instruct the second data base station to train the currently deployed interference management model to obtain model parameters. The second data base station is a data base station in the heterogeneous wireless network that can provide data services.

[0028] The management module is configured such that the second data base station aggregates the trained model parameters to obtain aggregated model parameters, updates the interference management model using the aggregated model parameters, and then performs interference management on the heterogeneous wireless network according to the updated interference management model.

[0029] According to another aspect of the embodiments of this application, an electronic device is provided, comprising:

[0030] Memory, used to store executable instructions; and

[0031] A display is used in conjunction with the memory to execute the executable instructions to perform the operation of any of the above-described interference management methods for heterogeneous wireless networks.

[0032] According to another aspect of the embodiments of this application, a computer-readable storage medium is provided for storing computer-readable instructions, which, when executed, perform the operation of any of the above-described interference management methods for heterogeneous wireless networking.

[0033] In this application, when the first wireless terminal detects that the first data base station it is accessing cannot provide data services, it can send an access request to the control base station in the heterogeneous wireless network.

[0034] By applying the technical solution of this application, when some data base stations in a heterogeneous wireless network shut down due to a deteriorating network environment, the control base station can provide data services to the disconnected terminals. Furthermore, the control base station instructs the target data base station to train the currently deployed interference management model to obtain new model parameters, which are then aggregated to update the interference management model deployed on each data base station based on the re-aggregated updated model parameters. This enables data base stations in heterogeneous wireless networks to obtain the latest interference management model matching the current network environment in real time for interference management of various devices in the wireless network.

It should be noted that the following application scenarios are shown only to facilitate understanding of the spirit and principles of this application, and the embodiments of this application are not limited in any way. Rather, the embodiments of this application can be applied to any applicable scenario.

[0053] This application also proposes an interference management method, apparatus, electronic device, and medium for heterogeneous wireless networking.

[0054] Figure 1 A schematic flowchart illustrating an interference management method for a heterogeneous wireless network according to an embodiment of this application is shown. The heterogeneous wireless network includes a control base station providing data services in a first frequency band and a data base station providing data services in a second frequency band, wherein the second frequency band is higher than the first frequency band. Figure 1 As shown, the method includes:

[0055] S101, when the first wireless terminal detects that the first data base station it is connected to cannot provide data services, it sends an access request to the control base station in the heterogeneous wireless network.

[0056] S102, after the control base station accesses the first wireless terminal, it sends control signaling to the second data base station. The control signaling is used to instruct the second data base station to train the currently deployed interference management model to obtain model parameters. The second data base station is a data base station that can provide data services in a heterogeneous wireless network.

[0057] S103, the second data base station aggregates the trained model parameters to obtain aggregated model parameters, updates the interference management model using the aggregated model parameters, and then performs interference management on the heterogeneous wireless network based on the updated interference management model.

[0058] Among related technologies, high- and low-frequency heterogeneous wireless networking based on the separation of control base stations and data base stations can not only improve regional coverage capabilities, but also significantly improve the overall spectrum efficiency of the system, providing a seamless high-speed experience for access users. It is a key networking method considered by the 6th generation mobile communication system (6G).

[0059] The high- and low-frequency heterogeneous wireless networking primarily utilizes control base stations to achieve basic coverage across the entire area via low-frequency bands, while data base stations use high-frequency bands for hotspot coverage and high-speed transmission. This aims to meet the demands of future 6G networks for higher data throughput, faster user experience rates, massive terminal connections, and lower latency. Furthermore, data base stations only handle RLC, MAC, and physical layer functions, significantly reducing deployment costs for operators. When data base stations detect a low number of users during certain periods, they can appropriately shut down some data base stations while maintaining user service quality, achieving dynamic cell switching. This reduces energy consumption and meets the green communication requirements of 6G development.

[0060] However, the realization of high- and low-frequency heterogeneous wireless networking still faces many challenges. First, the dense deployment of multi-layer nodes requires consideration of a trade-off between backhaul methods and deployment costs. Second, the dense deployment of low-power data base stations can lead to strong interference problems, and the switching on and off of data base stations will cause network interference fluctuations. Therefore, there is a coupling relationship between the dynamic switching of data base station cells and interference effects, which in turn affects user speeds.

[0061] In particular, since the interference management schemes deployed in 5G systems are static or quasi-static mechanisms, and in heterogeneous multi-layer networks, the radio environment is highly dynamic, which means that traditional interference coordination techniques first collect instantaneous global channel state information (CSI) and then calculate suboptimal solutions. However, collecting real-time global CSI in heterogeneous multi-layer networks is challenging, as global CSI usually changes rapidly, and the output solutions are often outdated or invalid, failing to provide efficient interference coordination. Furthermore, in systems with high- and low-frequency wireless cooperative networking, the dynamic switching of data stations adds a dimension to the dynamic changes in interference within the system.

[0062] Therefore, designing a high- and low-frequency heterogeneous wireless networking architecture that can adapt to 6G systems and proposing an efficient and dynamic interference coordination mechanism under this architecture are issues that need to be studied to ensure the performance of high- and low-frequency heterogeneous wireless networking.

[0063] To address the aforementioned issues, this invention proposes a method where, in a heterogeneous wireless network, when some data base stations shut down due to deteriorating network conditions, a control base station provides data services to the disconnected terminals. Furthermore, the control base station instructs the target data base stations to retrain new model parameters based on the current network environment and aggregate them, so that the interference management model deployed on each data base station is updated according to the re-aggregated updated model parameters.

[0064] Specifically, Figure 2 The heterogeneous wireless network proposed in this application includes multiple data base stations communicating and multiple control base stations.

[0065] In one approach, within the service area covered by the control base station, a user can instruct the control base station to provide control and data information related services in a low-frequency band (i.e., the first frequency band). Conversely, within the service area covered by the data base station, a user can instruct the data base station to provide data information related services during high-frequency periods (i.e., the second frequency band).

[0066] In one approach, this application can densely deploy data base stations in areas with high user access and high traffic demand to support a seamless high-speed user experience. In another approach, this application can also group data base stations that are geographically close and have overlapping coverage into the same heterogeneous wireless network, and centrally control the data base stations in a heterogeneous wireless network.

[0067] In one approach, this application selects one data base station from multiple data base stations as the target data base station, enabling it to establish centralized backhaul link communication with the control base station. Other data base stations within the heterogeneous wireless network no longer need to establish backhaul link connections with the control base station; they can directly establish backhaul links with the target data base station within the heterogeneous wireless network to complete backhaul communication. This reduces the backhaul link burden on the control base station and lowers signaling overhead.

[0068] In addition, in the heterogeneous wireless network proposed in this application, the various data base stations within the heterogeneous wireless network can cooperate in processing by sharing data, channel state information (CSI), scheduling information, and precoding matrix index (PMI) information, so as to improve the performance of cell edge users.

[0069] In one approach, the target data base station has strong computing and storage capabilities, and the data and channel status information in the data cells within the heterogeneous wireless network are uniformly located. Therefore, controlling the heterogeneous wireless networking of adjacent data base stations can more easily achieve inter-cell interference coordination, thereby meeting the high experience rate requirements of users in hotspot areas.

[0070] In the high- and low-frequency heterogeneous wireless networking proposed in this application, a wireless link backhaul mode can be adopted. The wireless backhaul combined with millimeter-wave massive MIMO beamforming technology provides huge antenna gain for the wireless backhaul link, which can effectively combat the relatively high path loss caused by rainfall and air absorption.

[0071] However, in ultra-dense network environments, as the number of data base stations deployed increases and the distance between them becomes closer within a limited space, the problem of co-level interference becomes increasingly severe. Therefore, for the high- and low-frequency cooperative networking architecture mentioned above, the interference management method proposed in this application only considers co-level interference between data base stations and the wireless terminals they serve.

[0072] Furthermore, in combination Figure 3As shown below, the interference management method for heterogeneous wireless networks proposed in this application will be described in detail:

[0073] Step 1: When the first data base station in the heterogeneous wireless network detects that the traffic in the area it serves is lower than the base station activation threshold, it automatically shuts down.

[0074] Step 2: When the first wireless terminal UE detects that the first data base station to which it is accessing cannot provide data services, it sends an access request to the control base station by sending a PUSCH reference signal through the control channel.

[0075] Step 3: Control the base station to allocate a subcarrier to the first UE that sends the message, allow the UE to access, and provide data services to the first UE.

[0076] Step 4: The control base station sends PDCCH control signaling to the target data base station via wireless backhaul to re-plan the access of wireless terminals in the heterogeneous wireless network.

[0077] 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 network.

[0078] The target data base station can be any number of data base stations from the second data base station. In one approach, it can be an idle data base station or a data base station with high equipment computing performance.

[0079] Step 6: Other data base stations collect interference measurement reports reported by the second wireless terminals connected to them.

[0080] Step 7: Other data base stations use the collected interference measurement reports to train their own deployed interference management models, obtain initial model parameters, and upload their initial model parameters to the target data base station.

[0081] Step 8: The target data base station re-aggregates the model parameters reported by other data base stations to obtain aggregated model parameters. The aggregated model parameters are then distributed to the other data base stations in the heterogeneous wireless network.

[0082] Step 9: The second data base station uses the aggregated model parameters to update its own deployed interference management model, thus obtaining an updated interference management model.

[0083] Step 10: The second data base station performs interference management on the heterogeneous wireless network based on the updated interference management model.

[0084] Interference management can include at least one of traffic management, resource allocation management, and channel power allocation management.

[0085] In this application, when the first wireless terminal detects that the first data base station it is accessing cannot provide data services, it can send an access request to the control base station in the heterogeneous wireless network. After the control base station accesses the first wireless terminal, it sends control signaling to the second data base station. The control signaling is used to instruct the second data base station to train and obtain model parameters corresponding to the current network environment information. The second data base station is a data base station in the heterogeneous wireless network that can provide data services. The second data base station aggregates the trained model parameters to obtain aggregated model parameters, updates the interference management model using the aggregated model parameters, and then performs interference management on the heterogeneous wireless network according to the updated interference management model.

[0086] By applying the technical solution of this application, when some data base stations in a heterogeneous wireless network shut down due to a deteriorating network environment, the control base station can provide data services to the disconnected terminals. Furthermore, the control base station instructs the target data base station to train the currently deployed interference management model to obtain new model parameters, which are then aggregated to update the interference management model deployed on each data base station based on the re-aggregated updated model parameters. This enables data base stations in heterogeneous wireless networks to obtain the latest interference management model matching the current network environment in real time for interference management of various devices in the wireless network.

[0087] Optionally, in another embodiment based on the method described above, after the control base station accesses the first wireless terminal, it sends control signaling to the second data base station, including:

[0088] After the control base station connects to the first wireless terminal, it sends control signaling to the target data base station;

[0089] The target data base station is at least one of the second data base stations.

[0090] Optionally, in another embodiment based on the method described above in this application, after sending control signaling to the target data base station, the method further includes:

[0091] The target data base station forwards the control signaling to the other data base stations in the second data base station;

[0092] The other data base stations collect interference measurement reports reported by the second wireless terminals connected to them, and use the interference measurement reports to train their own deployed interference management models to obtain initial model parameters.

[0093] The other data base stations each upload their own initial model parameters to the target data base station, so that the target data base station can collect multiple initial model parameters in the current heterogeneous wireless network.

[0094] Optionally, in another embodiment based on the method described above in this application, after the other data base stations have respectively uploaded their initial model parameters to the target data base station, the method further includes:

[0095] The target data base station aggregates the multiple initial model parameters collected to obtain the aggregated model parameters;

[0096] The target data base station distributes the aggregation model parameters to each of the other data base stations.

[0097] Optionally, in another embodiment based on the method described above in this application, interference management of the heterogeneous wireless network according to the updated interference management model includes:

[0098] The second data base station uses the aggregated model parameters to update its own deployed interference management model, thereby obtaining an updated interference management model;

[0099] The second data base station performs at least one of traffic management, resource allocation management, and channel power allocation management on the heterogeneous wireless network based on the updated interference management model.

[0100] Optionally, in another embodiment based on the method described above, after the first wireless terminal sends an access request to the control base station in the heterogeneous wireless network when it detects that the first data base station cannot provide data service, the method further includes:

[0101] The control base station allocates a subcarrier to the first wireless terminal so that the first wireless terminal can access the control base station using the subcarrier.

[0102] Optionally, in another embodiment based on the method described above in this application, in the heterogeneous wireless network, when the data base station detects that the traffic is lower than a preset threshold, it stops providing data services to the wireless terminal.

[0103] like Figure 4 As shown, this application further illustrates the solution:

[0104] Step 1: Each UE in the heterogeneous wireless network continuously receives measurement physical signals sent by the data base station for measuring network conditions with the data base station.

[0105] In one approach, the UE may first receive downlink signals (e.g., downlink physical signals) sent by multiple data base stations, including the interfering data base station, and detect downlink signals with excessively high interference energy from the interfering data base station based on the interference energy of each downlink signal, and treat them as interference signals.

[0106] Step 2: The UE obtains the measurement physical signals between the UE and the interfering data base station, as well as the corresponding configuration parameters, sent by the interfering data base station.

[0107] The configuration parameters can include one or more of the following:

[0108] The measurement includes the transmission period of the physical signal, the time-domain start position offset within the period of the physical signal, the number of repetitions / single transmission duration within the period of the physical signal, the transmission frequency / bandwidth of the physical signal, the subcarrier offset of the synchronization signal block, the subcarrier spacing of the physical signal, the sequence of the physical signal, and the frequency interval for transmitting the physical signal at a certain frequency.

[0109] In one approach, the UE obtains the configuration parameters of the physical measurement signals between the UE and the base station transmitted by the interfering base station by receiving user-specific signaling or system messages transmitted by the interfering base station. The UE then extracts the configuration parameters of the physical measurement signals between the UE and the base station carried within these user-specific signaling or system messages. Understandably, the purpose of the UE obtaining these configuration parameters is to receive the physical measurement signals between the UE and the base station more efficiently.

[0110] In another approach, the UE receives a physical measurement signal between the UE and the base station transmitted by the interfering base station. For example, this physical measurement signal can be a downlink physical signal within the interfering cell, such as a synchronization block or channel state information reference signal, or it can be a dedicated physical measurement signal between the UE and the base station transmitted by the interfering base station.

[0111] Furthermore, the physical measurement signal between the UE and the base station can be a time-domain periodic signal. As an example, the physical measurement signal between the UE and the base station is transmitted at a certain period, and multiple (e.g., at least two) copies of the physical measurement signal between the UE and the base station are repeatedly transmitted within the same transmission period, with the multiple copies within the same period having different copy index values.

[0112] Furthermore, an example of the aforementioned periodic inter-base station measurement physical signals could be a block of synchronization signals that interferes with the downlink transmission of the base station, including, for example, a downlink primary synchronization signal, a downlink secondary synchronization signal, and a demodulation reference signal for the physical broadcast channel.

[0113] Furthermore, the UE needs to measure the interference signal energy between the interfering base station and the UE, which have the same transmission period and the same frequency subband but different replica indices, in multiple physical measurement signals to obtain the interference signal strength between the base station and the UE for each replica index. The replica indices and interference signal strengths of M replicas with interference signal strengths greater than a predetermined threshold are taken as interference measurement results, and an interference measurement report is generated based on these results.

[0114] In one approach, M is a positive integer, and M <= X.

[0115] Where X is a positive integer, predetermined by the system, representing the maximum number of downlink beams transmitted by the base station in the same frequency subband.

[0116] Step 3: The UE reports the interference measurement report to the data base station that provides it with data services.

[0117] Furthermore, the UE can report interference measurement results by uplinking the interference measurement report to the data base station.

[0118] In one approach, the UE reports interference measurement results on the semi-persistent scheduling physical resources configured for the UE by the data base station. This method enables the UE to report interference measurement results to the data base station promptly and quickly.

[0119] Step 4: Each data base station is equipped with a DRL-based agent, which can be regarded as an intelligent agent. Each agent trains a model based on the data input from the measurement report and the initial interference management model.

[0120] Step 5: Optionally, if the data base station is in a heterogeneous wireless network of data base stations, in order to ensure the cooperation of interference coordination among data base stations in the heterogeneous wireless network and to avoid the situation where the data base station blindly pursues high transmission power to improve throughput and affects the performance of the entire heterogeneous wireless network, the data base station uploads the model parameters of the trained interference management model to the target data base station.

[0121] Step 6: Optionally, the target data base station aggregates the model parameters to obtain the global model parameters of the interference management model within the heterogeneous wireless network.

[0122] Step 7: Optionally, the target data base station distributes the aggregated global model parameters to each data base station within the heterogeneous wireless network.

[0123] Step 8: Each data base station uses the global model parameters to update its own deployed interference management model, thus obtaining an updated interference management model.

[0124] In one approach, the data base station in this application can make interference coordination decisions for base station power control based on an updated interference management model, so as to maximize the throughput of the wireless network system.

[0125] Step 9: The data base station detects that the traffic in the area it serves is lower than the base station activation threshold and automatically shuts down.

[0126] Step 10: When the UE detects that the first data base station to be accessed cannot provide data service, it sends an access request to the control base station by sending a PUSCH reference signal through the control channel.

[0127] Step 11: Control the base station to allocate subcarriers to the UE sending the message, allow the UE to access, and provide data services to the UE.

[0128] Step 12: The control base station sends PDCCH control signaling to the target data base station via wireless backhaul to re-plan user access.

[0129] 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.

[0130] Step 14: The data base station that remains operational collects real-time information from the network environment and updates the interference management model.

[0131] The information re-collected by the data base station includes the new access relationship between the UE and the data base station, as well as the interference measurement report reported by the UE corresponding to the new access relationship.

[0132] Step 15: Due to the shutdown of some data base stations, the smart agent on the base station becomes inactive, and the target data base station re-aggregates the data base station model parameters.

[0133] Step 16: The target data base station sends the aggregated interference management model parameters to the data base stations within the heterogeneous wireless network.

[0134] Understandably, the changing network environment of heterogeneous wireless networks necessitates that target data base stations retrain and aggregate new model parameters based on the current network environment. This allows for updating the interference management model deployed on each data base station using the re-aggregated model parameters. This updated interference management model enables more appropriate action decisions during subsequent autonomous interference coordination, thus achieving precise interference management for each device within the network.

[0135] Step 17: The data base station makes autonomous interference coordination decisions based on the new interference management model.

[0136] Understandably, the architecture and configuration method of this application can intelligently coordinate and control inter-cell interference in highly dynamic systems where base stations and data base stations are separated, while effectively improving the throughput of dense multi-layer heterogeneous RAN systems.

[0137] By applying the technical solution of this application, when some data base stations in a heterogeneous wireless network shut down due to a deteriorating network environment, the control base station can provide data services to the disconnected terminals. Furthermore, the control base station instructs the target data base station to train the currently deployed interference management model to obtain new model parameters, which are then aggregated to update the interference management model deployed on each data base station based on the re-aggregated updated model parameters. This enables data base stations in heterogeneous wireless networks to obtain the latest interference management model matching the current network environment in real time for interference management of various devices in the wireless network.

[0138] Optionally, in another embodiment of this application, such as Figure 5 As shown, this application also provides an interference management device for heterogeneous wireless networks. The heterogeneous wireless network includes a control base station providing data services in a first frequency band and a data base station providing data services in a second frequency band, wherein the second frequency band is higher than the first frequency band, wherein:

[0140] The transmitting module 202 is configured to send control signaling to the second data base station after the control base station accesses the first wireless terminal. The control signaling is used to instruct the second data base station to train the currently deployed interference management model to obtain model parameters. The second data base station is a data base station in the heterogeneous wireless network that can provide data services.

[0141] The management module 203 is configured to aggregate the trained model parameters of the second data base station to obtain aggregated model parameters, update the interference management model using the aggregated model parameters, and then perform interference management on the heterogeneous wireless network according to the updated interference management model.

This enables data base stations in heterogeneous wireless networks to obtain the latest interference management model matching the current network environment in real time for interference management of various devices in the wireless network.

[0146] In another embodiment of this application, the sending module 202 is configured to perform the following steps:

[0147] The target data base station forwards the control signaling to the other data base stations in the second data base station;

[0148] The other data base stations collect interference measurement reports reported by the second wireless terminals connected to them, and use the interference measurement reports to train their own deployed interference management models to obtain initial model parameters.

[0149] The other data base stations each upload their own initial model parameters to the target data base station, so that the target data base station can collect multiple initial model parameters in the current heterogeneous wireless network.

[0150] In another embodiment of this application, the sending module 202 is configured to perform the following steps:

[0151] The target data base station aggregates the multiple initial model parameters collected to obtain the aggregated model parameters;

[0152] The target data base station distributes the aggregation model parameters to each of the other data base stations.

[0153] In another embodiment of this application, the sending module 202 is configured to perform the following steps:

[0154] The second data base station uses the aggregated model parameters to update its own deployed interference management model, thereby obtaining the updated interference management model;

[0155] The second data base station performs at least one of traffic management, resource allocation management, and channel power allocation management on the heterogeneous wireless network based on the updated interference management model.

[0156] In another embodiment of this application, the sending module 202 is configured to perform the following steps:

[0157] The control base station allocates a subcarrier to the first wireless terminal so that the first wireless terminal can access the control base station using the subcarrier.

[0158] In another embodiment of this application, the sending module 202 is configured to perform the following steps:

[0159] In the heterogeneous wireless network, when the data base station detects that the traffic is lower than a preset threshold, it stops providing data services to the wireless terminal.
