Description

Technical Field

[0001] The present application relates to the field of communication technology, and in particular to a communication method, system, device, storage medium and program product. Background Art

[0002] The cell-free massive MIMO technology proposes the concept of clusters. A cluster includes one or more transmission and reception points, which can serve a terminal device. The communication data to be sent or received by each transmission and reception point is uniformly processed by a processing unit. By combining one or more distributed transmission and reception points into a large cell, the original cell boundaries are eliminated and unified scheduling is achieved.

[0003] However, in the above technology, the connection relationship between each transmission receiving point and the processing unit in a cluster is fixed at the beginning of cluster establishment, and the networking flexibility is poor. When the service or location of the terminal device changes, the network performance may deteriorate.

[0004] In view of this, how to achieve automatic and flexible networking based on the above-mentioned architecture of distributed transmission and receiving points and centralized processing of communication data is an urgent problem to be solved. Summary of the invention

[0005] The present application provides a communication method, system, device, storage medium and program product to realize automatic and flexible networking.

[0006] In a first aspect, a communication method is provided, which can be executed by a processing unit or a chip, circuit or device for a processing unit.

[0007] The method includes: configuring the first transmission receiving point to belong to the first cluster; and sending the first configuration information, wherein the first configuration information is used to indicate that the first transmission receiving point belongs to the second cluster. In this aspect, automatic re-clustering can be achieved, self-organizing distributed networking can be achieved, and the flexibility of networking can be improved. And the number and scale of clusters, and which cluster each transmission receiving point is divided into to serve the terminal device are determined by the processing unit and are flexible and dynamically variable. In the existing networking scheme, the connection relationship of each transmission receiving point will be determined at the beginning of cluster establishment and remain unchanged in subsequent operation. If you want to change this connection relationship, you need to shut down the service of the transmission receiving point and re-manually lay the network. In contrast, the scheme of this embodiment establishes a physical connection relationship between each transmission receiving point and each processing unit in advance, so that the transmission receiving point and the cluster can be adjusted online in a self-organized manner according to the service load and channel conditions of the terminal device under the condition of less impact on the cell service, so as to ensure the overall stable and optimal network performance, and improve the flexibility of networking. This embodiment can reduce the switching delay of the transmission receiving point between different clusters, ensure service continuity, and achieve a switching-free experience.

[0008] Exemplarily, the processing unit may also notify the processing unit corresponding to the second cluster of the configuration.

[0009] In a possible implementation, before sending the first configuration information, the method further includes: receiving at least one of the following network status information from the first transmission receiving point: the number of terminal devices in the first cluster served by the first transmission receiving point, the channel quality of the channel between the first transmission receiving point and the terminal devices in the first cluster served by the first transmission receiving point, and the communication rate between the first transmission receiving point and the terminal devices in the first cluster served by the first transmission receiving point. In this implementation, the processing unit can learn the communication status and load status between the transmission receiving point and the terminal devices in the cluster it manages, etc. by receiving at least one network status information from the first transmission receiving point, so that automatic clustering can be better performed based on the at least one network status information.

[0010] Exemplarily, the processing unit may also exchange the at least one network status information with processing units corresponding to other clusters.

[0011] In another possible implementation, the sending of the first configuration information includes: if the number of terminal devices in the first cluster served by the first transmission reception point is received, and the number of terminal devices in the first cluster served by the first transmission reception point is greater than or equal to a first threshold, the first configuration information is sent, and the number of terminal devices in the second cluster served by the first transmission reception point is less than or equal to a second threshold, wherein the second threshold is less than the first threshold. In this implementation, when the first transmission reception point belongs to the first cluster, the load of the first transmission reception point is too large, and the communication resources allocated by the processing unit to the first transmission reception point may not meet the communication requirements between the first transmission reception point and the terminal devices in the first cluster served by it, the first transmission reception point is assigned to the second cluster, and the second cluster can allocate sufficient communication resources to the first transmission reception point, thereby improving the network performance of the first transmission reception point and the terminal devices in the second cluster served by it.

[0012] In another possible implementation, the sending of the first configuration information includes: if the channel quality of the channel between the first transmission receiving point and the terminal device in the first cluster served by the first transmission receiving point is received, if the channel quality is less than or equal to a third threshold, sending the first configuration information, the channel quality of the channel between the first transmission receiving point and the terminal device in the second cluster served by the first transmission receiving point is greater than or equal to a fourth threshold, wherein the fourth threshold is greater than the third threshold. In this implementation, when the channel quality of the channel between the first transmission receiving point and the terminal device served by the first transmission receiving point in the cluster where it is currently located is poor, the clustering is adjusted according to the channel quality of the channel between the first transmission receiving point and the terminal devices in different clusters, so that the first transmission receiving point can better serve the terminal device, thereby improving the reliability of communication.

[0013] In another possible implementation, the sending of the first configuration information includes: if the communication rate between the first transmission reception point and the terminal device in the first cluster served by the first transmission reception point is received, if the communication rate is less than or equal to the fifth threshold, sending the first configuration information, the communication rate between the first transmission reception point and the terminal device in the second cluster served by the first transmission reception point is greater than or equal to the sixth threshold, wherein the sixth threshold is greater than the fifth threshold. In this implementation, when the communication rate between the first transmission reception point and the terminal device served by the first transmission reception point in the cluster where it is currently located is poor, the first transmission reception point is assigned to the second cluster, and the second cluster can allocate sufficient communication resources to the first transmission reception point, thereby improving the communication rate between the first transmission reception point and the terminal device served by it.

[0015] The method includes: the first transmission receiving point is configured to belong to the first cluster; and the first configuration information is received, and the first configuration information is used to indicate that the first transmission receiving point belongs to the second cluster. In this aspect, automatic re-clustering can be achieved, self-organizing distributed networking can be achieved, and the flexibility of networking can be improved; and the number and scale of clusters, and which cluster each transmission receiving point is divided into to serve the terminal device are determined by the processing unit and are flexibly and dynamically variable. In the existing networking scheme, the connection relationship of each transmission receiving point will be determined at the beginning of cluster establishment and remain unchanged in subsequent operation. If you want to change this connection relationship, you need to shut down the service of the transmission receiving point and re-manually lay the network. In contrast, the scheme of this embodiment establishes a physical connection relationship between each transmission receiving point and each processing unit in advance, so that the transmission receiving point and the cluster can be adjusted online in a self-organized manner according to the service load and channel conditions of the terminal device under the condition of less impact on the cell service, so as to ensure the overall stable and optimal network performance, and improve the flexibility of networking. This embodiment can reduce the switching delay of the transmission receiving point between different clusters, ensure service continuity, and achieve a switching-free experience.

[0070] In some deployments, the network device mentioned in the embodiments of the present application may be a device including a CU, or a DU, or a device including a CU and a DU, or a control plane CU node (central unit control plane (central unit-control plane, CU-CP)) and a user plane CU node (central unit user plane (central unit-user plane, CU-UP)) and a DU node. For example, the network device may include a gNB-CU-CP, a gNB-CU-UP, and a gNB-DU.

[0071] In some deployments, multiple RAN nodes collaborate to assist the terminal in achieving wireless access, and different RAN nodes implement part of the functions of the base station. For example, the RAN node can be a CU, DU, CU-CP, CU-UP, or RU. The CU and DU can be set separately, or can also be included in the same network element, such as a BBU. The RU can be included in a radio frequency device or a radio frequency unit, such as an RRU, AAU, or RRH.

[0072] In different systems, CU (or CU-CP and CU-UP), DU or RU may also have different names, but those skilled in the art can understand their meanings. For example, in the ORAN system, CU may also be called O-CU (open CU), DU may also be called O-DU, CU-CP may also be called O-CU-CP, CU-UP may also be called O-CU-UP, and RU may also be called O-RU. Any unit in the CU (or CU-CP, CU-UP), DU and RU in this application may be implemented by a software module, a hardware module, or a combination of a software module and a hardware module.

[0073] It should be understood that Figure 1 The number and type of each device in the communication system shown are for illustration only, and the present application is not limited thereto. In actual applications, the communication system may also include more terminal devices, more access network devices, and other network elements, such as core network devices, and / or network elements for implementing artificial intelligence functions.

[0074] It is understandable that all or part of the functions implemented by one or more of the terminal equipment, access network equipment, core network equipment, or network elements used to implement artificial intelligence functions can be virtualized, that is, implemented by one or more of the proprietary processors or general-purpose processors and the corresponding software modules. Among them, the terminal equipment and the access network equipment involve interfaces for air interface transmission, and the transceiver functions of the interfaces can be implemented by hardware. Core network equipment, such as operation administration and maintenance (OAM) network elements, can be virtualized. Optionally, one or more functions of the virtualized terminal equipment, access network equipment, core network equipment, or network elements used to implement artificial intelligence functions can be implemented by cloud devices, such as cloud devices in over the top (OTT) systems.

[0075] In view of the problems raised in the background technology, the present application provides a communication solution that can realize automatic re-clustering, realize self-organizing distributed networking, and improve the flexibility of networking. The solution can be called a cloud multi-input and multi-output (Cloud MIMO) solution.

[0076] Figure 2The present invention provides an architecture diagram of another communication system according to an embodiment of the present invention. The communication system 200 may include multiple processing units (m processing units are shown in the figure) 21, multiple transmission receiving points and multiple UEs (n UEs are shown in the figure), where m and n are positive integers. The multiple transmission receiving points are divided into multiple clusters according to location, network performance, etc., and each cluster includes one or more transmission receiving points. A processing unit is used to manage one or more clusters (a processing unit is shown in the figure to manage one cluster). Figure 2 In the example, transmission reception points 11-1m are divided into the first cluster, and the first cluster is managed by the first processing unit; transmission reception points 21-2m are divided into the second cluster, and the second cluster is managed by the second processing unit; and so on, transmission reception points m1-mm are divided into the mth cluster, and the mth cluster is managed by the mth processing unit. Each transmission reception point can serve one or more UEs, and one UE can be served by one or more transmission reception points under the cluster.

[0077] Exemplarily, the processing unit may be a base station, a chip in a DU, a DU or a CU, and the present application does not limit the form of the processing unit. The processing units are connected by circuits or optical fibers. The processing units can exchange the received data or processed data through the circuits or optical fibers. The processing unit may include one or more entities, which undertake the basic communication computing function, that is, responsible for processing the data reported by the transmission receiving points in the cluster it manages, and transmitting the processing results to the transmission receiving points; in addition to undertaking the basic communication computing function, in the present application, the processing unit may also divide the transmission receiving points into different clusters according to at least one network status information reported by the transmission receiving point, and re-cluster the transmission receiving points when at least one network status information is updated, so as to better serve the user and achieve better network performance. Exemplarily, the at least one network status information includes: the number of terminal devices served by the transmission receiving point, the channel quality of the channel between the transmission receiving point and the terminal device served by the transmission receiving point, and the communication rate between the transmission receiving point and the terminal device served by the transmission receiving point.

[0078] Exemplarily, the transmission receiving point includes a transmitting and receiving antenna, an internal processing circuit and a program, which is connected to each processing unit via a wire (such as an optical fiber, etc.). The transmission receiving point can be a TRP (for signal transmission only), an AAU, an RRU, etc., and the present application does not limit the form of the transmission receiving point. Based on the above system, the method provided in the embodiment of the present application is described in detail below.

[0079] like Figure 3 FIG. 1 is a flow chart of a communication method provided in an embodiment of the present application. Exemplarily, the method may include the following steps:

[0080] S301. The processing unit configures a first transmission reception point to belong to a first cluster.

[0081] During initial configuration, the processing unit configures the first transmission receiving point to belong to the first cluster. The processing unit is responsible for managing one or more first transmission receiving points in the first cluster. The first transmission receiving point is any first transmission receiving point among the multiple first transmission receiving points managed by the processing unit. Exemplarily, the processing unit may also notify other processing units of the configuration.

[0082] Exemplarily, the processing unit may send configuration information to indicate that the first transmission reception point belongs to the first cluster; the configuration may also be a factory configuration.

[0083] After the first transmission and reception point is configured to belong to the first cluster, communication is performed with at least one terminal device served by the first transmission and reception point, including uplink and / or downlink communication.

[0084] Specifically, a possible implementation method is that during the uplink communication process, the first transmission receiving point receives uplink data from at least one terminal device, and converges the received uplink data to the processing unit via optical fiber, etc., and the processing unit processes the data uniformly; during the downlink communication process, the processing unit can process the downlink data to be transmitted, and send the processed downlink data to the first transmission receiving point via optical fiber, etc., and the first transmission receiving point sends the data to the corresponding terminal device.

[0085] During the communication process, the first transmission receiving point may also receive network status information sent by the terminal device it serves, or monitor the network status information of the terminal device it serves. The first transmission receiving point may report the obtained network status information to the processing unit. Exemplarily, the process of obtaining the network status information may be periodic or triggered by an event, for example, the terminal device itself detects that its network status is poor and reports the network status information to the first transmission receiving point. Exemplarily, the network status information includes at least one of the following: the number of terminal devices in the first cluster served by the transmission receiving point, the channel quality of the channel between the transmission receiving point and the terminal devices in the first cluster served by the transmission receiving point, and the communication rate between the transmission receiving point and the terminal devices in the first cluster served by the transmission receiving point. The channel quality may include a rank indicator (RI), a channel quality indicator (CQI) and a precoding matrix indicator (PMI). Among them, RI is used to determine the number of streams for transmitting data to the terminal device; CQI is used to determine the modulation order and channel coding code rate for transmitting data to the terminal device; PMI is used to determine the precoding of data transmitted to the terminal device. The above description is applicable to the description of other embodiments throughout the text and will not be repeated.

[0086] The communication system includes multiple clusters, and the communication resources are generally fixed. According to the division of the cluster, certain communication resources are allocated to the cluster. If the traffic volume between the transmission receiving point and the terminal device in a cluster is large, the communication resources initially allocated to the cluster may not meet its business needs, resulting in poor network performance between the transmission receiving point and the terminal device; while the traffic volume between the transmission receiving point and the terminal device in some clusters is small, and there is surplus communication resources initially allocated to these clusters. After receiving the network status information, the processing unit of the first cluster can determine whether to re-cluster according to the network status information. The processing unit determines to re-cluster after judging that the current network status has deteriorated or the network performance does not meet expectations according to the network status information. Re-clustering will help improve network performance (such as increasing the overall communication rate). The impact on the business during this clustering process is relatively low.

[0087] S302. The processing unit sends first configuration information to the first transmission receiving point.

[0088] Correspondingly, the first transmission receiving point receives the first configuration information.

[0089] After the processing unit determines that re-clustering is required, it will allocate computing resources and storage resources for the clustering adjustment to be performed, establish processing tasks, and prepare for clustering calculations. Exemplarily, the processing unit can execute a clustering optimization program with the goal of "better network performance" and can use a clustering algorithm to calculate the clustering results.

[0090] The processing unit can convert the calculated clustering result into an adjustment instruction, namely, the first configuration information, wherein the first configuration information is used to indicate that the first transmission receiving point belongs to the second cluster. The processing unit transmits the first configuration information to the first transmission receiving point, instructing the first transmission receiving point to form a new clustering relationship according to the first configuration information, and completes the clustering adjustment. After the first transmission receiving point receives the first configuration information, since the first configuration information is used to attribute the first transmission receiving point to the second cluster, the subsequently received communication data and network status information are sent to the processing unit of the second cluster for processing.

[0091] like Figure 4A As shown, it is a schematic diagram of an example of re-clustering provided by an embodiment of the present application. In the initial configuration, it is divided into four clusters, each of which includes one or more transmission receiving points. The four clusters can be managed by one or more processing units. Figure 4AIn the example, the first cluster includes more transmission receiving points than other clusters. After receiving the network status information sent by these transmission receiving points, the processing unit of the first cluster determines that the number of terminal devices served by transmission receiving points 1 and 2 is greater than the threshold, or the channel quality of the channels between transmission receiving points 1 and 2 and the terminal devices they serve is poor, or the communication rate between transmission receiving points 1 and 2 and the terminal devices they serve is low. Therefore, the processing unit of the first cluster determines to re-cluster transmission receiving points 1 and 2, and assigns transmission receiving points 1 to the second cluster and transmission receiving points 2 to the third cluster. It should be understood that Figure 4A The clusters to which the transmission reception point 1 and the transmission reception point 2 belong have changed, which does not emphasize that the physical locations of the above two transmission reception points have changed.

[0092] like Figure 4B As shown, it is a schematic diagram of another example of re-clustering provided by an embodiment of the present application. In the initial configuration, it is divided into four clusters, each of which includes one or more transmission receiving points. The four clusters can be managed by one or more processing units. Figure 4B The first cluster includes more transmission receiving points than other clusters, and the load of the processing unit of the first cluster is relatively large. Therefore, a fifth cluster can be added to divide some transmission receiving points in the first cluster into the fifth cluster, and the processing unit of the fifth cluster is responsible for managing the transmission receiving points belonging to the fifth cluster.

[0093] This embodiment is described by taking a processing unit responsible for managing a cluster (i.e., the first cluster) as an example. In another embodiment, the processing unit may be responsible for managing multiple clusters. When a processing unit is used to manage multiple clusters, the services related to the multiple clusters are all processed internally by the processing unit. Clusters, transmission receiving points, and UEs all have corresponding identifiers, and the processing unit establishes a mapping relationship between the transmission receiving points and UEs under each cluster. Therefore, when receiving services related to any cluster, corresponding processing can be performed.

[0094] Exemplarily, the first cluster and the second cluster may be managed by the same processing unit or by different processing units. When the first cluster and the second cluster may be managed by the same processing unit, the processing unit itself determines the clustering result and sends the clustering result to the first transmission receiving point. When the first cluster and the second cluster are managed by different processing units, the processing unit corresponding to the first cluster may forward the received network status information to the processing unit corresponding to the second cluster, and the processing unit corresponding to the second cluster may determine the clustering result and send the clustering result to the first transmission receiving point; or the processing unit corresponding to the first cluster may determine the clustering result based on the received network status information, and notify the processing unit corresponding to the second cluster of the clustering result, and the processing unit corresponding to the second cluster may send the clustering result to the first transmission receiving point.

[0095] Exemplarily, the solution of the present application can be applied to scenarios where there are communication needs indoors. Taking an industrial manufacturing plant as an example, there are a large number of video surveillance cameras (a type of terminal equipment) that need to transmit uplink video. The uplink bandwidth requirement for a single camera varies from a few megabytes to more than ten megabytes, depending on the bit rate. For another example, the artificial intelligence (AI) quality inspection camera (a type of terminal equipment) on a production line may require up to hundreds of megabytes of uplink bandwidth for a single user. Figure 5 As shown, it is a schematic diagram of the architecture of a communication system in a scenario provided by an embodiment of the present application. Multiple transmission receiving points can be set up in different areas in an industrial manufacturing plant. Each area includes multiple transmission receiving points. The multiple transmission receiving points in the area can be set up at a certain interval. Each transmission receiving point is responsible for receiving data transmitted by a camera near it. The processing unit can regard the area as a cluster. Figure 5 Two clusters are exemplified in the figure, wherein the first cluster is managed by the first processing unit and the second cluster is managed by the second processing unit. Each cluster includes one or more transmission receiving points. The one or more transmission receiving points in each cluster are interconnected, and the one or more transmission receiving points in each cluster are connected to the processing unit that manages the cluster. The processing units of each cluster can also be interconnected, and the one or more transmission receiving points in each cluster can also be connected to the processing units of other clusters. The workshop may adjust the production line layout according to the production order, and the business distribution may change accordingly. The location and / or number of the above-mentioned video surveillance cameras or AI quality inspection cameras may change, so the communication network is required to have self-planning capabilities to adapt to the adjustment of business needs. Based on the solution provided in this embodiment, clustering can be re-performed to ensure network performance.

[0096] According to a communication method provided by an embodiment of the present application, the processing unit can automatically re-cluster and realize self-organizing distributed networking, thereby improving the flexibility of networking; in addition, in this embodiment, the number and scale of clusters, and which cluster each transmission receiving point is divided into to serve the terminal device are determined by the processing unit and are flexibly and dynamically variable. In the existing networking scheme, the connection relationship of each transmission receiving point will be determined at the beginning of cluster establishment and remain unchanged in subsequent operation. If you want to change this connection relationship, you need to shut down the service of the transmission receiving point and re-lay the network manually. In contrast, since the scheme of this embodiment establishes a physical connection relationship between each transmission receiving point and each processing unit in advance, it can adjust the affiliation relationship between the transmission receiving point and the cluster online in a self-organized manner according to the service load and channel conditions of the terminal device with little impact on the cell service, in order to ensure the overall stable and optimal network performance, and improve the flexibility of networking. This embodiment can reduce the switching delay of the transmission receiving point between different clusters, ensure service continuity, and achieve a switching-free experience.

[0097] In a communication scenario, the processing unit may be a processing chip or a processing circuit in the DU. Figure 6 As shown, it is a schematic diagram of another communication system exemplified by an embodiment of the present application, the system includes a DU (the figure illustrates that the DU includes two processing chips: a first processing chip and a second processing chip) and multiple first transmission receiving points. Each processing chip manages one or more clusters, each cluster includes one or more first transmission receiving points, and each processing chip is connected to one or more first transmission receiving points in its corresponding cluster through an optical fiber / connector. Multiple processing chips are electrically connected.

[0098] like Figure 7 As shown, the example of the embodiment of the present application is based on Figure 6 FIG. 1 is a flow chart of a communication method of a communication system shown in FIG. 1 . Exemplarily, the communication method may include the following steps:

[0099] S701. The first processing chip configures the first transmission reception point to belong to the first cluster.

[0100] The first processing chip is Figure 3 A specific example of the processing unit in the embodiment shown. The specific implementation of this step can be referred to Figure 3 Step S301 of the illustrated embodiment.

[0101] During initial configuration, the first processing chip configures the first transmission receiving point to belong to the first cluster. The first processing chip is responsible for managing one or more first transmission receiving points in the first cluster. The first transmission receiving point is any first transmission receiving point among the multiple first transmission receiving points managed by the first processing chip.

[0102] Exemplarily, the first processing chip may also notify the second processing chip of the configuration, wherein the first processing chip and the second processing chip are processing chips in the DU.

[0103] Exemplarily, the first processing chip may send configuration information to indicate that the first transmission reception point belongs to the first cluster; the configuration may also be a factory configuration.

[0104] S702. The terminal device communicates with the first transmission and reception point. For example, the terminal device sends a first uplink signal to the first transmission and reception point. The first uplink signal includes a first pilot and first uplink data.

[0105] The step is Figure 3 Further supplementary operations are performed on the basis of the illustrated embodiment.

[0106] After the first transmission receiving point receives the first uplink signal, it parses the first uplink signal to obtain a first pilot and first uplink data, sends the first uplink data to the first processing chip for processing, and obtains at least one of the following first network status information based on the first pilot: the channel quality of the channel between the first transmission receiving point and the terminal device in the first cluster served by the first transmission receiving point, and the communication rate between the first transmission receiving point and the terminal device in the first cluster served by the first transmission receiving point.

[0107] Exemplarily, the first pilot may be a sounding reference signal (SRS), the first transmission receiving point receives the first pilot, and measures the first pilot to obtain the channel quality of the uplink channel between the first transmission receiving point and the terminal device in the first cluster served by the first transmission receiving point. For a time division duplexing (TDD) system, the uplink and downlink channels are reciprocal, and the first transmission receiving point can obtain the channel quality of the downlink channel by the channel quality of the uplink channel.

[0108] Exemplarily, the first transmission and reception point may also send a downlink reference signal to the terminal device it serves. The terminal device measures the downlink reference signal to obtain the channel quality of the downlink channel and returns the channel quality to the first transmission and reception point.

[0109] Exemplarily, the communication rate between the first transmission reception point and the terminal devices in the first cluster served by the first transmission reception point may be reported by the terminal devices after measurement, or may be obtained by monitoring by the first transmission reception point itself.

[0110] In addition, since the first transmission reception point serves the terminal device, the first transmission reception point can also obtain the number of terminal devices in the first cluster served by the first transmission reception point.

[0111] S703. The first transmission receiving point reports at least one first network state information obtained based on the first pilot to the first processing chip. Correspondingly, the first processing chip receives the at least one first network state information.

[0112] The step is Figure 3 Further supplementary operations are performed on the basis of the illustrated embodiment.

[0113] Exemplarily, the first transmission receiving point may report the at least one first network status information to the first processing chip. The reporting may be periodic or after receiving abnormal network status information.

[0114] S704. The first processing chip determines whether to re-cluster based on at least one first network state information.

[0115] The step is Figure 3 Further supplementary operations are performed on the basis of the illustrated embodiment.

[0116] After receiving at least one network status information and the first data, the first processing chip provides a communication service function for the terminal device on the one hand, and on the other hand, can determine whether to re-cluster according to the at least one first network status information received. The first processing chip will start clustering adjustment when it determines that the current network status has deteriorated or does not meet expectations, and that re-clustering will be beneficial to better network performance (such as an increase in the overall communication rate). The clustering process has little impact on the communication process.

[0117] S705. After the first processing chip determines to re-cluster, it calculates a new clustering result.

[0118] The step is Figure 3 Further supplementary operations are performed on the basis of the illustrated embodiment.

[0119] After the first processing chip determines that re-clustering is required, it will allocate computing resources and storage resources for its own upcoming clustering adjustment, establish processing tasks, and prepare for clustering calculations.

[0120] Exemplarily, the first processing chip may execute a clustering optimization program with the goal of "better network performance" and may use a clustering algorithm to calculate and obtain a clustering result.

[0121] The clustering adjustment may be implemented in the following ways, but the present application is not limited thereto:

[0122] In a possible implementation, if the number of terminal devices in the first cluster served by the first transmission reception point is received by the first processing chip in the above step S703, and the number of terminal devices in the first cluster served by the first transmission reception point is greater than or equal to the first threshold, the number of terminal devices in the first cluster served by the first transmission reception point is too large, that is, the load of the first transmission reception point is too large, and the first processing chip is responsible for the operation of the data received by the first transmission reception point, etc., and the computing resources of each first processing chip are certain, which will affect the response speed, etc.; in addition, the communication system allocates certain communication resources to each cluster. Since the load of the first transmission reception point is too large, the communication resources allocated to the first transmission reception point by the first processing chip may not meet the communication requirements between the first transmission reception point and the terminal devices it serves. Therefore, it is determined to re-cluster. Before clustering, the first processing chip can obtain information about other clusters, and learn that the number of terminal devices in the second cluster is less than or equal to the second threshold, and the communication resources allocated to each transmission reception point in the second cluster by the second processing chip may be surplus, then the first processing chip configures the first transmission reception point to belong to the second cluster. After the first transmission reception point belongs to the second cluster, the second processing chip can allocate communication resources to the newly added first transmission reception point. After adjusting the clustering, the number of terminal devices in the second cluster served by the first transmission receiving point is less than or equal to the second threshold, which can improve the response speed of the first transmission receiving point to the terminal devices and improve the network performance of the first transmission receiving point and the terminal devices it serves. The second threshold is less than the first threshold. With this implementation, when the first transmission receiving point belongs to the first cluster, the load of the first transmission receiving point is too large, and the communication resources allocated by the first processing chip to the first transmission receiving point may not meet the communication requirements between the first transmission receiving point and the terminal devices it serves, the first transmission receiving point is assigned to the second cluster, and the second cluster can allocate sufficient communication resources to the first transmission receiving point, thereby improving the network performance of the first transmission receiving point and the terminal devices it serves.

[0123] In another possible implementation, the first transmission receiving point will not only measure the channel quality of the channel between the first transmission receiving point and the terminal device served by the first transmission receiving point in the cluster (first cluster) where it is currently located, but also measure the channel quality of the channel between the first transmission receiving point and the terminal devices in other clusters. If the first processing chip receives the channel quality of the channel between the first transmission receiving point and the terminal devices in the first cluster served by the first transmission receiving point in the above step S703, if the channel quality is less than or equal to the third threshold, the first processing chip determines to adjust the clustering. The reason for the poor channel quality may be that the first processing chip allocates fewer communication resources to the first transmission receiving point, or the terminal devices in the first cluster have moved and are far away from the first transmission receiving point. The first processing chip can obtain the remaining communication resources of other clusters (for example, the second cluster) and the channel quality of the channel between the first transmission receiving point and the terminal devices in the second cluster, and learn that the channel quality of the channel between the first transmission receiving point and the terminal devices in the second cluster is greater than or equal to the fourth threshold, and the fourth threshold is greater than the above third threshold, then the first processing chip adjusts the clustering and configures the first transmission receiving point to belong to the second cluster. After the first transmission reception point is assigned to the second cluster, the second processing chip can allocate communication resources to the newly added first transmission reception point. With this implementation, when the channel quality between the first transmission reception point and the terminal device served by the first transmission reception point in the cluster where it is currently located is poor, the clustering is adjusted according to the channel quality between the first transmission reception point and the terminal devices in different clusters, so that the first transmission reception point can better serve the terminal device, thereby improving the reliability of communication.

[0124] In another possible implementation, if the first processing chip receives the communication rate between the first transmission reception point and the terminal device in the first cluster served by the first transmission reception point in the above step S703, if the communication rate is less than or equal to the fifth threshold, the first processing chip determines to adjust the clustering. The reason for the low communication rate may be that the first processing chip allocates fewer communication resources to the first transmission reception point, or the terminal device in the first cluster has moved and is far away from the first transmission reception point. The first processing chip can obtain the remaining communication resources of other clusters (for example, the second cluster), and then the first processing chip adjusts the clustering and configures the first transmission reception point to belong to the second cluster. Exemplarily, the second cluster may be the cluster with the most remaining communication resources among all clusters, or the cluster with a better communication rate between its transmission reception point and the terminal device it serves. After the first transmission reception point belongs to the second cluster, the second processing chip can allocate communication resources to the newly added first transmission reception point. After belonging to the second cluster, the communication rate of the first transmission reception point and the terminal device in the second cluster it serves is improved. For example, the communication rate between the first transmission reception point in the second cluster and the terminal device served by the first transmission reception point is greater than or equal to the sixth threshold, wherein the sixth threshold is greater than the fifth threshold. With this implementation, when the communication rate between the first transmission receiving point and the terminal device served by the first transmission receiving point in the cluster where it is currently located is poor, the first transmission receiving point is assigned to the second cluster, and the second cluster can allocate sufficient communication resources to the first transmission receiving point, thereby improving the communication rate between the first transmission receiving point and the terminal device it serves.

[0125] Exemplarily, the first to sixth thresholds may be pre-set in the first transmission receiving point, and the thresholds may be determined by an OAM method, a protocol predefined method or other methods.

[0126] S706. The first processing chip sends the clustering result to the second processing chip. Correspondingly, the second processing chip receives the clustering result.

[0127] The step is Figure 3 Further supplementary operations are performed on the basis of the illustrated embodiment.

[0128] The second processing chip is responsible for managing one or more transmission reception points in the second cluster. Therefore, after the first processing chip determines that the first transmission reception point belongs to the second cluster, the second processing chip can be notified of the clustering result.

[0129] S707: The second processing chip sends the first configuration information to the first transmission receiving point. Correspondingly, the first transmission receiving point receives the first configuration information.

[0130] The step is Figure 3 Another implementation of step S302 of the illustrated embodiment.

[0131] The first configuration information is used to indicate that the first transmission reception point belongs to the second cluster.

[0132] In this step, the second processing chip can convert the calculated clustering result into an adjustment instruction, namely, first configuration information, and transmit it to the first transmission receiving point to instruct the first transmission receiving point to form a new clustering relationship according to the first configuration information to complete the clustering adjustment.

[0133] Alternatively, one may refer to Figure 3 In step S302 of the illustrated embodiment, the first processing chip may also send the first configuration information to the first transmission receiving point.

[0134] After the first transmission and reception point is re-clustered, the communication process with the terminal device continues, including uplink and / or downlink communication. The clustering adjustment has little impact on the communication process.

[0135] S708. The terminal device sends a second uplink signal to the first transmission and reception point. Correspondingly, the first transmission and reception point receives the second uplink signal.

[0136] The second uplink signal includes a second pilot and second uplink data.

[0137] The step is Figure 3 Further supplementary operations are performed on the basis of the illustrated embodiment.

[0138] S709. The first transmission receiving point reports at least one second network status information obtained based on the second pilot to the second processing chip. Correspondingly, the second processing chip receives the at least one second network status information.

[0139] After the first transmission receiving point receives the second uplink signal, it can obtain at least one second network status information based on the second pilot. The specific implementation of this step can refer to step S703, which will not be repeated here. Figure 3 Further supplementary operations are performed on the basis of the illustrated embodiment.

[0140] S710. The second processing chip monitors whether the network performance after clustering adjustment meets the requirement based on at least one second network status information.

[0141] After the clustering adjustment, the second processing chip will perform anomaly detection within a certain period of time, and judge whether the change of network performance after the clustering adjustment meets expectations based on at least one second network status information reported by the first transmission receiving point, that is, whether the network performance index improves as expected. If no abnormality occurs, it is determined that the clustering adjustment is successful and the network status continues to be monitored; otherwise, the clustering process of S704 to S707 is executed.

[0142] The step is Figure 3Further supplementary operations are performed on the basis of the illustrated embodiment.

[0143] S711. The network performance meets the requirements, and the first transmission receiving point and the terminal device continue to communicate in the second cluster.

[0144] The communication includes uplink communication and downlink communication. For uplink communication, the first transmission receiving point receives uplink data sent by the terminal device and sends the received uplink data to the second processing chip for processing; for downlink communication, the first transmission receiving point receives downlink data processed by the second processing chip and sends the downlink data to the terminal device.

[0145] The step is Figure 3 Further supplementary operations are performed on the basis of the illustrated embodiment.

[0146] According to a communication method provided in an embodiment of the present application, the processing chip of the DU can be responsible for cluster management, realize automatic re-clustering, realize self-organizing distributed networking, and improve the flexibility of networking.

[0147] In another communication scenario, the wireless access network may include a CU and multiple DUs, and the processing unit includes the CU and the DU. Figure 8 As shown, it is a schematic diagram of another communication system exemplified by an embodiment of the present application, the communication system includes a CU, multiple DUs (two DUs are exemplified in the figure: DU1 and DU2) and multiple first transmission receiving points. The CU can be connected to multiple DUs through optical fibers, etc., and is responsible for managing multiple DUs. Each DU in the multiple DUs manages one or more clusters, each cluster includes one or more first transmission receiving points, and each DU is connected to one or more first transmission receiving points in its corresponding cluster through optical fibers / connectors. Multiple DUs are also connected to each other through optical fibers / connectors.

[0148] like Fig. 9 As shown, the example of the embodiment of the present application is based on Figure 8 FIG. 1 is a flow chart of a communication method of a communication system shown in FIG. 1 . Exemplarily, the method may include the following steps:

[0149] S901. CU configures the first transmission reception point to belong to the first cluster.

[0150] In this embodiment, CU is responsible for clustering. DU1 is responsible for managing the first cluster, and DU2 is responsible for managing the second cluster. Figure 3 The processing operation of the processing unit in the illustrated embodiment is divided into two parts: one part is handled by the CU, and the other part is handled by DU1 and DU2. The CU is responsible for clustering adjustment, and DU1 and DU2 are responsible for notifying the transmission receiving points in the corresponding cluster of the CU configuration.

[0151] During initial configuration, the CU configures the first transmission reception point to belong to the first cluster. The first transmission reception point is any transmission reception point in the system.

[0152] After DU1 obtains the configuration of CU, it manages the first transmission and reception point according to the configuration of CU, including allocating communication resources to the first transmission and reception point.

[0153] Exemplarily, CU can send configuration information to DU1, indicating that the first transmission receiving point belongs to the first cluster. DU1 can transparently transmit the configuration information to the first transmission receiving point, or perform adaptive processing on the configuration information in terms of format and other aspects on the DU1 end before sending it to the first transmission receiving point; CU and DU1 can also be configured at the factory to configure the first transmission receiving point to belong to the first cluster.

[0154] S902. The terminal device communicates with the first transmission and reception point. For example, the terminal device sends a first uplink signal to the first transmission and reception point. The first uplink signal includes a first pilot and first uplink data.

[0155] The step is Figure 3 Further supplementary operations based on the illustrated embodiment. The specific implementation of this step can refer to Figure 7 Step S702 of the illustrated embodiment will not be described in detail here.

[0156] S903. The first transmission receiving point reports at least one first network status information obtained based on the first pilot to DU1. Correspondingly, DU1 receives the at least one first network status information.

[0157] The step is Figure 3 Further supplementary operations are performed on the basis of the illustrated embodiment.

[0158] Exemplarily, the first transmission receiving point may periodically report at least one first network status information to the DU, or the first transmission receiving point may report at least one first network status information to the DU after receiving abnormal network status information.

[0159] S904. DU1 reports the at least one first network status information to CU.

[0160] The step is Figure 3 Further supplementary operations are performed on the basis of the illustrated embodiment.

[0161] After each DU receives at least one first network status information reported by the transmission reception point in its corresponding cluster, it forwards the received at least one first network status information to the CU.

[0162] S905. The CU determines whether to re-cluster based on at least one first network state information.

[0163] The step is Figure 3 Further supplementary operations based on the illustrated embodiment. The specific implementation of this step can refer to Figure 7 The difference between step S704 of the illustrated embodiment is that in this example, it is the CU that determines whether to re-cluster.

[0164] S906. After the CU determines to re-cluster, it calculates a new clustering result.

[0165] The step is Figure 3 Further supplementary operations based on the illustrated embodiment. The specific implementation of this step can refer to Figure 7 The difference between step S705 of the illustrated embodiment is that in this example, the CU calculates the new clustering result.

[0166] S907. CU sends first configuration information to DU2. Correspondingly, DU2 receives the first configuration information.

[0167] Based on the architecture of this embodiment, the CU first sends the first configuration information to the DU2.

[0168] The first configuration information is used to indicate that the first transmission reception point belongs to the second cluster.

[0169] Exemplarily, the CU may also send the first configuration information to DU1 to notify DU1 that the first transmission and reception point belongs to the second cluster.

[0170] Alternatively, DU2 may also forward the first configuration information to DU1.

[0171] S908. DU2 forwards the first configuration information to the first transmission and reception point. Correspondingly, the first transmission and reception point receives the first configuration information.

[0172] Based on the architecture of this embodiment, after receiving the first configuration information, DU2 forwards the first configuration information to the first transmission receiving point.

[0173] Steps S907 and S908 are used to implement Figure 3 Step S302 in the illustrated embodiment.

[0174] After the clustering adjustment, the first transmission reception point communicates with the terminal device in the second cluster, including uplink and / or downlink communication:

[0175] S909. The terminal device sends a second uplink signal to the first transmission and reception point, where the second uplink signal includes a second pilot and second uplink data.

[0176] The step is Figure 3 Further supplementary operations are performed on the basis of the illustrated embodiment.

[0177] After receiving the second uplink signal, the first transmission and reception point can obtain at least one second network status information based on the second pilot.

[0178] S910. The first transmission receiving point reports at least one second network status information obtained based on the second pilot to DU2. Correspondingly, DU2 receives the at least one second network status information.

[0179] The step is Figure 3 Further supplementary operations based on the illustrated embodiment. The specific implementation of this step can refer to Figure 7 Step S709 of the illustrated embodiment will not be described in detail here.

[0180] S911. DU2 reports the received at least one second network status information to the CU.

[0181] The step is Figure 3 Further supplementary operations are performed on the basis of the illustrated embodiment.

[0182] S912. The CU monitors whether the network performance after the clustering adjustment meets the requirement based on at least one second network status information.

[0183] After clustering adjustment, CU will perform anomaly detection within a certain period of time, and judge whether the change of network performance after clustering adjustment meets expectations based on at least one second network status information, that is, whether the network performance indicators have improved as expected. If no anomaly occurs, it is determined that the cluster adjustment is successful and the network status continues to be monitored; otherwise, the clustering process of S905 to S908 is executed. This step is Figure 3 Further supplementary operations are performed on the basis of the illustrated embodiment.

[0184] S913. The network performance meets the requirements, and the first transmission receiving point communicates with the terminal device in the second cluster.

[0185] The communication includes uplink communication and downlink communication. For uplink communication, the first transmission receiving point receives the uplink data sent by the terminal device and sends the received uplink data to DU2 for processing; for downlink communication, the first transmission receiving point receives the downlink data processed by DU2 and sends the downlink data to the terminal device.

[0186] The clustering process has little impact on the business.

[0187] The step is Figure 3 Further supplementary operations are performed on the basis of the illustrated embodiment.

[0188] According to a communication method provided in an embodiment of the present application, after each DU receives at least one network status information reported by at least one first transmission receiving point in the cluster it is responsible for managing, it is summarized to the CU, and the CU determines whether to re-cluster. The CU can obtain the network status information of each cluster, so that the clustering adjustment can be performed better.
