[0029] The purpose, features, and advantages of this application will be further explained in conjunction with the embodiments and with reference to the accompanying drawings. Detailed Implementation

[0030] It should be understood that the specific embodiments described herein are merely illustrative of the technical solutions of this application and are not intended to limit this application.

[0031] Currently, with the development of communication technology, people's demand for fiber optic communication technology is gradually increasing. 2.0 FTTR (fiber-to-the-room) technology connects wireless routers (APs) in different rooms or locations in homes or small and medium-sized enterprises using fiber optic cables, thereby providing high-bandwidth, high-reliability connections between multiple APs. It can utilize a point-to-multipoint optical distribution network to achieve connections between the master control AP and slave APs.

[0032] However, in related technologies, the FTTR protocol currently lacks effective means to handle edge node communication. If a terminal device happens to be at the edge of the service area of ​​two basic service sets, its communication quality will be significantly reduced, resulting in network congestion, data transmission delays, reduced connection stability, and packet jitter. These problems are particularly severe when the terminal device is stationary in the edge area. Furthermore, in scenarios with densely deployed fiber optic home networks, multiple devices (including master and slave devices) are highly likely to experience co-channel and adjacent-channel interference, especially in the extremely limited 2.4GHz spectrum and the scarce spectrum resources of 5GHz. The lack of joint scheduling technology at the protocol level and transmission technology imposes many limitations on the collaborative allocation of wireless resources among multiple devices in networking scenarios.

[0033] To address the aforementioned technical problems, this application proposes a solution. Specifically, it generates a joint beamforming matrix for a joint scheduling group and sends the joint beamforming matrix to each functional unit within the joint scheduling group. Each functional unit in the joint scheduling group then uses the joint beamforming matrix for data transmission. Based on this solution, the MCU coordinates the communication resources of each functional unit in the joint scheduling group. Furthermore, this application generates a joint beamforming matrix for each functional unit in the joint scheduling group to transmit data, effectively reducing the impact of interference in the same frequency range and thus improving the communication quality of edge devices in the FTTR system.

[0034] The execution subject of this embodiment can be a computing service device with data processing, network communication and program execution functions, such as a tablet computer, personal computer, mobile phone, etc., or an electronic device or device joint scheduling system that can realize the above functions.

[0035] To better understand the technical solution of this application, a detailed description will be provided below in conjunction with the accompanying drawings and specific implementation methods.

[0036] Referring to Figure 1, which is a schematic diagram of the networking scenario of an FTTR system; as shown in Figure 1, the method proposed in this application embodiment is mainly applied to an FTTR system, and the FTTR system includes an MFU (Multi-function Unit) and an SFU (Single-function Unit). The MFU is the master device in the FTTR system, and the SFU is the slave device in the FTTR system. The MFU can control each SFU to communicate with the user terminal STA in the optical distribution network.

[0037] Based on the scenario diagram shown in Figure 1, a first embodiment of the service routing method of this application is proposed.

[0038] Referring to Figure 2, which is a flowchart illustrating a first exemplary embodiment of the device joint scheduling method of this application, the method is applied to a multifunctional unit (MFU) in a fiber optic home networking (FTTR) system, and includes steps S10 to S20.

[0039] Step S10: Generate a joint beamforming matrix for the joint scheduling group and send the joint beamforming matrix to each functional unit in the joint scheduling group.

[0040] A joint scheduling group is a collection of fiber optic network communication devices that perform joint scheduling. A joint scheduling group can consist of each scheduled SFU, or it can consist of both the MFU performing the joint scheduling and the scheduled SFUs. If there are multiple MFUs in the FTTR system, they can be divided into MFUs with the highest authority and other MFUs with lower authority based on their control privileges. The MFU with the highest authority can control the MFUs with lower authority. Therefore, a joint scheduling group can also consist of a low-authority, scheduled MFU and a scheduled SFU, or it can consist of a joint scheduling MFU with the highest authority, a scheduled SFU, and a low-authority, scheduled MFU. In this embodiment, the MFU in the FTTR system, which performs the execution, has the highest control authority relative to other functional devices in the FTTR system; therefore, the joint scheduling group is also determined by this MFU.

[0041] Furthermore, the joint beamforming matrix is ​​the matrix used by various functional units within the joint scheduling group to perform beamforming. Beamforming technology, also known as transmit beamforming or transmit beamforming, is an advanced antenna technology used in wireless communication, primarily to improve signal transmission efficiency and coverage. Beamforming optimizes the signal propagation path, reduces interference, and improves signal quality at the receiver by concentrating the energy of the transmitted signal in a specific direction. Beamforming utilizes an array antenna (an antenna group composed of multiple antenna elements) to control the direction of the transmitted signal. By adjusting the phase and amplitude between the individual antenna elements, beamforming can form one or more high-gain beams directly pointed at the target receiver. This precise directional control allows the signal to bypass obstacles, reducing path loss and interference, thereby enhancing the performance of the communication link.

[0042] When the joint scheduling group consists of all scheduled SFUs, the MFU generates the joint beamforming matrix for the joint scheduling group and then sends the joint beamforming matrix to the SFUs in the joint scheduling group. When the joint scheduling group consists of the MFU with the highest authority performing joint scheduling and all scheduled SFUs, the MFU does not need to send the joint beamforming matrix to itself; it only needs to send the joint beamforming matrix to the SFUs in the joint scheduling group. When the joint scheduling group consists of the MFU with the highest authority performing joint scheduling, the lower-authority MFUs under scheduling, and the scheduled SFUs, the MFU with the highest authority needs to send the generated joint beamforming matrix to both the lower-authority MFUs under scheduling and the scheduled SFUs.

[0043] Step S20: Data transmission is performed using the joint beamforming matrix by each functional unit in the joint scheduling group.

[0044] The joint beamforming matrix contains the signal transmission direction and gain coefficient of each functional unit in the joint scheduling group when transmitting data to the user terminal. Thus, unified scheduling of wireless communication resources of each device in the FTTR system can be achieved.

[0045] Furthermore, the data transmission technology adopted by each functional unit in this embodiment is JT (Joint Transmission) technology. That is, in this embodiment, the functional units in the joint scheduling group can use the joint beamforming matrix to perform joint data transmission. JT technology is an advanced wireless signal processing technology, mainly used to improve the data rate for edge users of wireless networks and the overall network spectral efficiency. JT technology improves network coverage, enhances signal quality, and reduces interference by coordinating signal transmission and processing among multiple APs, thereby enhancing user experience. The core of JT technology is coordination among multiple wireless devices that jointly serve the same user or user group, especially those users located in overlapping service areas of multiple wireless devices. In this embodiment, the terminal device receiving data is the target STA on the user side. The target STA may include the user's mobile phone, computer, etc. Each functional unit in the joint scheduling group synchronously sends the data that needs to be sent to the target STA on the user side to the target STA at the same time; that is, each functional unit in the joint scheduling group jointly serves the target STA.

[0046] In this embodiment, each unit in the joint scheduling group transmits data with the target STA on the user side. If the joint scheduling group consists of each scheduled SFU, after each functional unit in the joint scheduling group obtains the joint beamforming matrix, the MFU controls each SFU in the joint scheduling group to send data to the target STA at the same time, thereby realizing joint data transmission. If the joint scheduling group consists of both the MFU that controls the scheduling of each SFU and each scheduled SFU, after each functional unit in the joint scheduling group obtains the joint beamforming matrix, in addition to each SFU in the joint scheduling group transmitting data with the STA on the user side at the same time under the control of the MFU, the MFU also transmits data with the target STA at the same time. This enables joint data transmission between the joint scheduling group and the target STA. Similarly, when the joint scheduling group consists of a low-privilege scheduled MFU and a scheduled SFU, the highest-privilege MFU controls the low-privilege scheduled MFU and the scheduled SFU within the joint scheduling group to send data to the target STA at the same time. When the joint scheduling group consists of a joint scheduling MFU with the highest privileges, a low-privilege scheduled MFU, and a scheduled SFU, the highest-privilege MFU, the low-privilege scheduled MFU, and the scheduled SFU send data to the target STA at the same time.

[0047] In this embodiment, a joint beamforming matrix for the joint scheduling group is generated and sent to each functional unit in the joint scheduling group. Each functional unit in the joint scheduling group then uses the joint beamforming matrix to perform data transmission. Based on the coordination of communication resources among the functional units in the joint scheduling group by the MCU, this application also generates a joint beamforming matrix for each functional unit in the joint scheduling group to perform data transmission according to the joint beamforming matrix. This effectively reduces the impact of interference in the same frequency domain, thereby improving the communication quality of edge devices in the FTTR system.

[0048] In one feasible implementation, a joint beamforming matrix of the joint scheduling group is generated, and the joint beamforming matrix is ​​sent to each functional unit in the joint scheduling group. Step S5 may be included before step S10.

[0049] Step S5: Determine the joint scheduling group.

[0050] In one embodiment, the joint scheduling group in this application is determined by the MFU.

[0051] For example, the step of determining the joint scheduling group may include steps A1 to A2.

[0052] Step A1: Determine the target SFU that meets the preset constraints from at least one single-function unit (SFU) in the FTTR system.

[0053] In one embodiment, when a target SFU that meets preset constraints exists in the FTTR system, the process of determining a joint scheduling group is initiated.

[0054] For example, the preset constraints include one or more of the following: historical joint beamforming matrix update constraints, SFU received signal strength constraints, SFU communication delay constraints, SFU communication transmission accuracy constraints, and SFU communication channel quantity constraints.

[0055] When the joint scheduling group consists of the scheduled SFUs or the joint scheduling group consists of the MFU performing joint scheduling and the scheduled SFUs, the historical joint beamforming matrix update constraint is that the historical joint beamforming matrix received by the SFU needs to undergo timeout aging, that is, the SFU needs to acquire a new joint beamforming matrix to adapt to the current FTTR system; the SFU received signal strength condition is that the SFU's received signal strength is less than a first preset threshold; the SFU communication delay condition is that the delay of wireless communication between the SFU and a certain associated device increases significantly within a certain period of time; the SFU communication transmission accuracy condition is that the packet error rate of line communication between the SFU and the corresponding associated device decreases significantly within a certain period of time and is less than a second preset threshold and / or the average SNR (Signal-to-Noise Ratio) value of a certain spatial stream of a certain device associated with the SFU decreases significantly and is lower than the threshold; the SFU communication channel number condition is that the average condition number of the channel estimated by the SFU from the signals sent by the associated device decreases significantly. In addition, the first and second preset thresholds can be set according to the actual situation, and this application does not impose any restrictions on them. When generating joint scheduling groups, one or more of the above-mentioned preset constraints can be used in combination to cope with different business scenarios and business needs.

[0056] Step A2: Determine the joint scheduling group corresponding to the target SFU.

[0057] A joint scheduling group is a cluster of fiber optic network communication equipment that accepts joint scheduling. A joint scheduling group can consist of individual SFUs under scheduling, or it can consist of a MFU performing joint scheduling and individual SFUs under scheduling. A joint scheduling group can also consist of an MFU with the highest authority performing joint scheduling, lower-authority MFUs under scheduling, and individual SFUs under scheduling.

[0058] For example, the step of determining the joint scheduling group corresponding to the target SFU may include steps A21 to A23.

[0059] Step A21: In response to the joint scheduling request instruction, preset statistical information query data is sent to each SFU in the FTTR system so that each SFU in the FTTR system can generate target statistical data based on the statistical information query data.

[0060] Referring to Figure 3, which is a data interaction diagram for determining the joint scheduling group in this embodiment; as shown in Figure 3, when the joint scheduling group consists of each scheduled SFU or is composed of both the MFU performing the joint scheduling and each scheduled SFU, the MFU responds to the joint scheduling request instruction by sending preset statistical information query data to each SFU in the FTTR system, such as SFU_1, SFU_2, ..., SFU_N in Figure 3. The statistical information query data is used to query the communication status between each SFU under the MFU and the corresponding STA (Station, user terminal).

[0061] The MFU receives joint scheduling request commands through WMCI (Wi-Fi Management and Control Interface), FMCI (Fiber Management and Control Interface), or other management channels.

[0062] Referring to Figure 4, which is a schematic diagram of the optical physical layer and data link layer architecture of the FTTR system in this embodiment; as shown in Figure 4, in the FTTR system, message data is transmitted to the F-adapter (fiber optic adapter) and W-adapter (Wi-Fi adapter) of the data link layer through WMCI, FMCI or other management channels, and then transmitted to the FEM adapter (front end adapter). The FEM adapter realizes message transmission from the optical physical layer and the data link layer, and generates the PHY payload (physical payload, optical physical layer data frame payload); in addition, the DTA (Data Transfer Agent) generates the PHY header (physical header, optical physical layer data frame header) according to F-PLOAM (Fiber-based Physical Layer OAM, fiber-based physical layer operation management and maintenance technology) and E-OAM (Ethernet OAM, Ethernet-based operation management and maintenance technology). Based on the architecture shown in Figure 4, this embodiment sends preset statistical information query data to each SFU in the FTTR system through WMCI, FMCI or other management channels. Each SFU responds to the received information query data by generating target statistical data to respond to the information query data.

[0063] In addition, the joint scheduling request instruction can be triggered by any SFU that meets the preset restrictions, or it can be automatically triggered by the MFU. This implementation does not limit this.

[0064] For example, the statistical information query data includes bandwidth data corresponding to each SFU in the FTTR system, and the bandwidth data includes current working bandwidth data and maximum working bandwidth data.

[0065] The bandwidth data corresponding to each SFU is the bandwidth parameter of the SFU. The bandwidth data can include the current working bandwidth data and the maximum working bandwidth data, which are used to query the current working bandwidth and the maximum working bandwidth of each SFU, respectively.

[0066] For example, the statistical information query data includes wireless communication status data between each SFU and its corresponding STA in the FTTR system. The wireless communication status data includes one or more of the following: signal strength data, average channel condition quantity data, spatial average signal-to-noise ratio data, and communication delay data.

[0067] Wireless communication status data characterizes the communication status between each SFU and its corresponding STA in an FTTR system. Signal strength data represents the signal strength of the STA corresponding to a specific MAC (Media Access Control) address or IP (Internet Protocol) address; average channel condition count data represents the average number of channel conditions for a STA corresponding to a specific MAC address or IP address; spatial average signal-to-noise ratio data represents the spatial average SNR for a STA corresponding to a specific MAC address or IP address; and communication delay data represents the average communication delay between an SFU and the STA corresponding to a specific MAC address or IP address.

[0068] Step A22: Receive the target statistical data sent by each SFU in the FTTR system.

[0069] In this embodiment, the MFC receives target statistical data generated by each SFU in the FTTR system. Generally, the target statistical data contains a large amount of information, which would place a tremendous burden on a wired backhaul system, necessitating the introduction of additional source compression coding techniques. For the FTTR system, the high bandwidth characteristic of fiber optic backhaul can effectively solve this problem and reduce the system's load.

[0070] Step A23: Based on the target statistical data and the preset joint scheduling group generation strategy, determine the joint scheduling group corresponding to the target SFU.

[0071] The joint scheduling group generation strategy in this embodiment can be designed based on the content of statistical information query data. The joint scheduling group generation strategy is used to select functional units whose target statistical data meets the communication conditions required for joint scheduling to form a joint scheduling group.

[0072] In this embodiment, the joint scheduling group is determined; a joint beamforming matrix for the joint scheduling group is generated and sent to each functional unit in the joint scheduling group; and each functional unit in the joint scheduling group uses the joint beamforming matrix to perform data transmission. Based on the scheme of this application, the joint scheduling group is determined, thereby coordinating the communication resources of each functional unit in the joint scheduling group through the MCU; this application also generates a joint beamforming matrix so that each functional unit in the joint scheduling group can perform data transmission according to the joint beamforming matrix, which can effectively reduce the impact of co-channel interference, thereby improving the communication quality of edge devices in the FTTR system.

[0073] Based on the first embodiment of this application, a second embodiment of this application is proposed. In the second embodiment of this application, content that is the same as or similar to that in the first embodiment described above can be referred to the above description and will not be repeated hereafter. Based on this, please refer to Figure 5, which is a flowchart illustrating the second embodiment of the device joint scheduling method of this application; as shown in Figure 5, each functional unit in the joint scheduling group includes each SFU in the joint scheduling group, and the step of generating the joint beamforming matrix of the joint scheduling group and sending the joint beamforming matrix to each functional unit in the joint scheduling group may include steps S101 to S103.

[0074] Step S101: In response to receiving air interface acquisition success data sent by any SFU in the joint scheduling group, notify each SFU in the joint scheduling group of measurement process start data, so that each SFU in the joint scheduling group can generate measurement response data according to the measurement process start data.

[0075] Referring to Figure 6, which is a data interaction diagram for generating the joint beamforming matrix in this embodiment; as shown in Figure 6, when the MFU receives air interface acquisition success data sent by any SFU in the joint scheduling group through WMCI, FMCI, or other management channels, the MFU senses that any SFU in the joint scheduling group (SFU_2 in Figure 6) has successfully acquired the air interface. The MFU then notifies the SFUs in the joint scheduling group (SFU_1 and SFU_2 in Figure 6) of the start of the measurement process through WMCI, FMCI, or other management channels, instructing the SFUs in the joint scheduling group to send a preset measurement frame to the STA at the other end at a preset time. After receiving the response frame returned by the STA at the other end, the SFU in the joint scheduling group generates measurement response data based on the response frame and sends the measurement response data back to the MFU.

[0076] Before an SFU within a joint scheduling group sends a preset measurement frame to a STA at the other end, clock synchronization is required to determine the preset time. This ensures that all SFUs within the joint scheduling group can uniformly send the preset measurement frame to the STA at the preset time. In this embodiment, clock synchronization between the MFU and SFU can be performed using the 1588 protocol. The 1588 protocol, also known as PTP (Precision Time Protocol), is a network protocol used for synchronizing clocks in a distributed system. This protocol is primarily used in applications requiring high-precision clock synchronization. The 1588 protocol provides sub-microsecond-level clock synchronization accuracy between network devices. It achieves this accuracy by measuring the time it takes for a message to travel from one device to another. PTP uses a master-slave architecture for clock synchronization. One device in the system acts as the master clock, and the other devices act as slave clocks. Slave clocks adjust their local clocks by exchanging timestamp information with the master clock. Furthermore, clock synchronization is performed through several types of messages.

[0077] Sync (synchronization message): Sent by the master clock to mark a specific point in time.

[0078] Follow_Up: Sends after the synchronization message, providing the precise time of the synchronization message.

[0079] Delay_Req (Delay Request Message): Sent from the clock to measure round-trip delay.

[0080] Delay_Resp (Delay Response Message): The master clock's response to the delay request, providing the time when the slave clock sent the delay request message.

[0081] In addition, PTP can have multiple candidate master clocks. The protocol includes the BMCA (Best Master Clock Algorithm) to select the clock with the highest time accuracy as the master clock.

[0082] Step S102: Receive the measurement response data sent by each SFU in the joint scheduling group, and generate the joint beamforming matrix of the joint scheduling group based on the measurement response data and preset service requirements.

[0083] After receiving the measurement response data sent by each SFU in the joint scheduling group, the MFU generates the joint beamforming matrix of the joint scheduling group based on the measurement response data and the preset service requirements.

[0084] For example, the measurement response data includes one or more of the following: beamforming singular value decomposition matrix, beamforming signal-to-noise ratio, beamforming channel matrix, and average message air interface transmission delay.

[0085] The beamforming singular value decomposition matrix is ​​the matrix or a compressed matrix required to solve the beamforming matrix using the SVD (Singular Value Decomposition) method. In this embodiment, the beamforming singular values ​​may include the V matrix; the beamforming signal-to-noise ratio is the average SNR corresponding to the spatial stream of communication between the SFU and STA, or the SNR value at a specific frequency point; the beamforming channel matrix is ​​the effective channel matrix or a compressed channel matrix in the protocol. In this embodiment, the beamforming channel matrix can be denoted as the H matrix; the average message air interface transmission delay is the average delay of message data transmission in the air interface.

[0086] In one embodiment, if the number of receiving antennas of the STA is 2, that is, the number of spatial streams of data transmitted by each SFU in the joint scheduling group is 2, denoted as the first spatial stream and the second spatial stream respectively, and the joint scheduling group consists of SFU_1 and SFU_2 as shown in Figure 6, then the V matrix V1 corresponding to SFU_1 can be expressed as: V1=[v 1,1 ,v 1,2 ]

[0087] Among them, v 1,1 This represents the submatrix corresponding to the communication between SFU_1 and STA on the first spatial stream, v 1,2 This represents the submatrix corresponding to the communication between SFU_1 and STA on the second spatial stream;

[0088] The V matrix V2 corresponding to SFU_2 can be represented as: V2=[v 2,1 ,v 2,2 ]

[0089] Among them, v 2,1 This represents the submatrix corresponding to the communication between SFU_2 and STA on the first spatial stream, v 2,2 This represents the submatrix corresponding to the communication between SFU_2 and STA on the second spatial stream;

[0090] The beamforming signal-to-noise ratio (SNR) corresponding to SFU_1 can be expressed as:

[0091] Where, μ 11 Let μ be the signal-to-noise ratio of SFU_1 on the first spatial flow. 12 The signal-to-noise ratio of SFU_1 on the second spatial stream;

[0092] The beamforming signal-to-noise ratio (SNR2) corresponding to SFU_2 can be expressed as:

[0093] Where, μ 21 Let μ be the signal-to-noise ratio of SFU_2 on the first spatial flow. 22The signal-to-noise ratio of SFU_2 on the second spatial stream;

[0094] Select the spatial stream with better communication status corresponding to each SFU. The spatial stream with better communication status corresponding to SFU_1 is: μ 1max =max(μ 11 ,μ 12 ), and its corresponding column is v 1max This can be determined by referring to V1.

[0095] Similarly, we obtain a spatial flow with relatively good communication conditions corresponding to SFU_2: μ 2max =max(μ 11 ,μ 12 ), and its corresponding column is v 2max This can be determined by referring to V2.

[0096] Finally, in this embodiment, the joint beamforming matrix P corresponding to the joint scheduling group is:

[0097] In another embodiment, if the number of receiving antennas of the STA is 2, that is, the number of spatial streams of data transmitted by each SFU in the joint scheduling group is 2, denoted as the first spatial stream and the second spatial stream respectively, and the joint scheduling group consists of SFU_1 and SFU_2 as shown in Figure 6, and the STA uses MMSE (Minimum Mean Square Error) for data reception, then the method for generating the joint beamforming matrix P of the joint scheduling group is as follows: H 1,eff =Σ1V1 H 2,eff =Σ2V2 H eff =[H 1,eff H 2,eff ]

[0098] In this embodiment, the beamforming singular values ​​may include a V matrix and a Σ matrix. Therefore, in the above formula, Σ1 and V1 are the V matrix and Σ matrix corresponding to SFU_1, respectively. 1,eff Here, Σ2 and V2 are the effective channel matrices for communication between SFU_1 and STA, respectively, and H is the effective channel matrix for communication between SFU_1 and STA. 2,eff H represents the effective channel matrix for communication between SFU_2 and STA. eff The effective channel matrix within the communication space is formed by SFU_1, SFU_2, and STA.

[0099] Furthermore, ρ is a simple and practical method for representing the equivalent signal-to-noise ratio, which can be expressed as: ρ=(SNR1+SNR2) / 2

[0100] Wherein, SNR1 is the signal-to-noise ratio corresponding to SFU_1, and SNR2 is the signal-to-noise ratio corresponding to SFU_2.

[0101] Both Σ1 and Σ2 can be estimated from the uplink channel based on the mutual difference between the uplink and downlink channels.

[0102] Step S103: Send the joint beamforming matrix to each SFU in the joint scheduling group.

[0103] After generating the joint beamforming matrix, the MFU sends the joint beamforming matrix to each SFU in the joint scheduling group, so that each SFU in the joint scheduling group can transmit data according to the joint beamforming matrix.

[0104] In this embodiment, in response to receiving air interface acquisition success data sent by any SFU in the joint scheduling group, measurement process start data is announced to each SFU in the joint scheduling group, so that each SFU in the joint scheduling group can generate measurement response data according to the measurement process start data; the measurement response data sent by each SFU in the joint scheduling group is received, and a joint beamforming matrix of the joint scheduling group is generated according to the measurement response data and preset service requirements; the joint beamforming matrix is ​​sent to each SFU in the joint scheduling group.

[0105] Based on the scheme proposed in this application, more efficient utilization of radio resources is achieved through the collaborative work of SFUs within the joint scheduling group. When one SFU successfully acquires air interface resources, the entire joint scheduling group can quickly respond and begin the measurement process. The application of the joint beamforming matrix can reduce the loss of radio signal data during transmission, improving the efficiency and stability of signal transmission.

[0106] Based on the first embodiment of this application, a third embodiment of this application is proposed. In this third embodiment, content that is the same as or similar to that in the first embodiment described above can be referred to the above description and will not be repeated hereafter. Based on this, please refer to Figure 7, which is a flowchart illustrating the third embodiment of the device joint scheduling method of this application; as shown in Figure 7, the step of determining the joint scheduling group corresponding to the target SFU based on the target statistical data and the preset joint scheduling group generation strategy includes steps B1 to B3:

[0107] Step B1: Based on the target statistical data and the joint scheduling group generation strategy, determine at least one schedulable SFU.

[0108] Corresponding to the statistical information query data, the target statistical data may also include one or more of the following: bandwidth data corresponding to each SFU in the FTTR system and wireless communication status data between each SFU and its corresponding STA in the FTTR system. If the target statistical data includes the current operating bandwidth and maximum operating bandwidth of each SFU in the FTTR system, then in this embodiment, according to the joint scheduling group generation strategy, the SFU in the FTTR system with the same current operating bandwidth as the target SFU is determined to be a schedulable SFU. If the target statistical data includes signal strength data between STAs corresponding to each SFU in the FTTR system, then the SFU whose absolute value of the difference in signal strength with the target SFU is less than a third preset threshold is determined to be a schedulable SFU. If the target statistical data includes average channel condition data, then the SFU whose average channel condition is greater than a fourth preset threshold can be determined to be a schedulable SFU. The target statistical data may also include spatial flow data during communication between each SFU and STA. This application can determine SFUs whose spatial flow is complementary to that of the target SFU as schedulable SFUs based on the joint scheduling group generation strategy. The target statistical data may also include the current channel matrix. In this embodiment, the correlation of the current channel matrix between any SFU and the target SFU is calculated, and SFUs with a correlation less than a fifth preset threshold are determined as schedulable SFUs. It is understood that before the above process of determining schedulable SFUs begins, the target SFU is assumed to be a schedulable SFU to determine the joint scheduling group corresponding to the target SFU.

[0109] In addition, the third, fourth, and fifth preset thresholds mentioned in this embodiment can be set according to the actual implementation situation to adapt to different business or scenario needs. This embodiment does not limit them here.

[0110] Step B2, together with the at least one schedulable SFU, constitutes a first device set.

[0111] In this embodiment, the joint scheduling group can be composed of the MFU that performs joint scheduling and each SFU that is scheduled. In this embodiment, the MFU that performs joint scheduling and at least one schedulable SFU constitute the first device set.

[0112] Step B3: Determine that the first set of devices is the joint scheduling group corresponding to the target SFU.

[0113] In this embodiment, the first set of devices is determined to be the joint scheduling group corresponding to the target SFU, so that data transmission can be performed through the MFU and SFU in the joint scheduling group.

[0114] For example, the step of using the joint beamforming matrix to transmit data through each functional unit in the joint scheduling group includes steps C1 to C2.

[0115] Step C1: In response to receiving air interface acquisition success data sent by any SFU in the joint scheduling group, synchronize the pre-acquired data to be sent to each SFU in the joint scheduling group.

[0116] Referring to Figure 8, which is a schematic diagram of data interaction based on the joint beamforming matrix in this embodiment; as shown in Figure 8, after the joint scheduling group is determined, if the MFU receives successful air interface acquisition data sent by any SFU in the joint scheduling group, it indicates that any SFU in the joint scheduling group has an air interface available for data transmission. The MFU will synchronize the pre-acquired data to be transmitted to each SFU in the joint scheduling group. The data to be transmitted can be any data that needs to be transmitted through the optical distribution network of the FTTR system. If the joint scheduling group includes MFU, SFU_1, and SFU_2, then the data to be transmitted will be synchronized to SFU_1 and SFU_2.

[0117] Step C2: During the preset joint transmission time, the data to be transmitted is sent to the corresponding target wireless user terminal (STA) according to the joint beamforming matrix, and each SFU in the joint scheduling group is controlled to send the data to be transmitted to the target STA according to the joint beamforming matrix.

[0118] In this embodiment, the MFU and each SFU in the joint scheduling group have completed clock synchronization. Then, at the preset joint transmission time, the MFU sends the data to be transmitted to the corresponding target STA according to the generated joint beamforming matrix, and at the same time controls each SFU in the joint scheduling group to send the data to be transmitted to the target STA according to the generated joint beamforming matrix.

[0119] In this embodiment, at least one schedulable SFU is determined based on the target statistical data and the joint scheduling group generation strategy; the at least one schedulable SFU constitutes a first device set; and the first device set is determined as the joint scheduling group corresponding to the target SFU. In this embodiment, the MFU not only controls the SFU to transmit data by issuing a joint beamforming matrix, but also transmits data itself according to the generated joint beamforming matrix, thereby maximizing the utilization of radio resources in the FTTR system and improving data transmission efficiency.

[0120] Based on the first embodiment of this application, a fourth embodiment of this application is proposed. In this fourth embodiment, content that is the same as or similar to that in the first embodiment described above can be referred to the above description and will not be repeated hereafter. Based on this, please refer to Figure 9, which is a flowchart illustrating the fourth embodiment of the device joint scheduling method of this application; as shown in Figure 9, the step of determining the joint scheduling group corresponding to the target SFU based on the target statistical data and the preset joint scheduling group generation strategy includes steps D1 to D2.

[0121] Step D1: Based on the target statistical data and the joint scheduling group generation strategy, determine at least one schedulable SFU.

[0122] In this embodiment, at least one schedulable SFU is determined in the same way as step B1 in the third embodiment above, and will not be described again here.

[0123] Step D2: Determine the second set of devices consisting of at least one schedulable SFU as the joint scheduling group corresponding to the target SFU.

[0124] In this embodiment, the joint scheduling group consists of each scheduled SFU. In this embodiment, the second set of devices composed of the at least one schedulable SFU is determined as the joint scheduling group corresponding to the target SFU.

[0125] For example, the step of using the joint beamforming matrix to transmit data through each functional unit in the joint scheduling group may include steps E1 to E2.

[0126] Step E1: In response to receiving air interface acquisition success data sent by any SFU in the joint scheduling group, synchronize the pre-acquired data to be sent to each SFU in the joint scheduling group.

[0127] Referring to the third embodiment described above, as shown in Figure 8, after determining the joint scheduling group, if the MFU receives air interface acquisition success data sent by any SFU in the joint scheduling group, it indicates that any SFU in the joint scheduling group has an air interface available for data transmission. The MFU then synchronizes the pre-acquired data to be transmitted to each SFU in the joint scheduling group. The data to be transmitted can be any data that needs to be transmitted through the optical distribution network of the FTTR system. If the joint scheduling group includes MFU, SFU_1, and SFU_2, then the data to be transmitted is synchronized to SFU_1 and SFU_2.

[0128] Step E2: During the preset joint transmission time, control each SFU in the joint scheduling group to send the data to be transmitted to the corresponding target STA according to the joint beamforming matrix.

[0129] In this embodiment, the MFU and each SFU in the joint scheduling group have completed clock synchronization. Therefore, at the preset joint transmission time, this embodiment controls each SFU in the joint scheduling group to simultaneously send the data to be transmitted to the target STA according to the generated joint beamforming matrix.

[0130] In this embodiment, at least one schedulable SFU is determined based on the target statistical data and the joint scheduling group generation strategy; the second set of devices composed of the at least one schedulable SFU is determined as the joint scheduling group corresponding to the target SFU. In this embodiment, the joint scheduling group does not include the MFU itself, in order to avoid the load overload problem caused by the MFU simultaneously transmitting data and controlling each SFU, making the wireless resource coordination in the FTTR system more reasonable and reliable.

[0131] In some implementations, a joint scheduling group can consist of a highest-authority MFU performing joint scheduling, lower-authority scheduled MFUs, and scheduled SFUs. Alternatively, the joint scheduling group may exclude the highest-authority MFU and consist only of lower-authority scheduled MFUs and scheduled SFUs. In the above implementations, the lower-authority scheduled MFU functions similarly to the SFU in the third or fourth implementation. This MFU only receives the joint beamforming matrix generated by the highest-authority MFU and, under the control of the highest-authority MFU, performs joint data transmission with other functional units within the joint scheduling group according to the joint beamforming matrix at a preset joint transmission time. Since the MFU chip has superior hardware performance compared to the SFU, adding a large number of MFUs to joint data transmission can significantly improve data transmission efficiency. MFUs typically have stronger signal transmission and reception capabilities, which helps improve network coverage, especially in areas with weak signals. Furthermore, due to the collaborative work between MFUs, joint beamforming technology can optimize signal transmission direction, reduce signal interference, and improve signal quality.

[0132] Based on the scenario diagram shown in Figure 1, a fifth embodiment of the service routing method of this application is proposed.

[0133] Referring to Figure 10, which is a flowchart illustrating a fifth exemplary embodiment of the device joint scheduling method of this application, the method is applied to an SFU in an FTTR system, wherein the SFU is any SFU in the joint scheduling group determined by the MFU in the FTTR system, and the method includes steps M10 to M20.

[0134] Step M10: Receive the joint beamforming matrix of the joint scheduling group generated and sent by the MFU.

[0135] A joint scheduling group is a cluster of fiber optic network communication equipment that accepts joint scheduling. A joint scheduling group can consist of individual SFUs under scheduling, or it can consist of a Management Function Unit (MFU) performing joint scheduling and individual SFUs under scheduling. A joint scheduling group can also consist of an MFU performing joint scheduling with the highest authority, lower-authority MFUs under scheduling, and individual SFUs under scheduling. In this embodiment, the MFU in the execution entity FTTR system has the highest communication control authority relative to other functional devices in the FTTR system. Furthermore, the joint scheduling group is also determined by this MFU.

[0136] Furthermore, the joint beamforming matrix is ​​the matrix used by various functional units within the joint scheduling group to perform beamforming. Beamforming technology, also known as transmit beamforming or transmit beamforming, is an advanced antenna technology used in wireless communication, primarily to improve signal transmission efficiency and coverage. Beamforming optimizes the signal propagation path, reduces interference, and improves signal quality at the receiver by concentrating the energy of the transmitted signal in a specific direction. Beamforming utilizes an array antenna (an antenna group composed of multiple antenna elements) to control the direction of the transmitted signal. By adjusting the phase and amplitude between the individual antenna elements, beamforming can form one or more high-gain beams directly pointed at the target receiver. This precise directional control allows the signal to bypass obstacles, reducing path loss and interference, thereby enhancing the performance of the communication link.

[0137] When the joint scheduling group consists of all scheduled SFUs, the MFU generates the joint beamforming matrix for the joint scheduling group and then sends the joint beamforming matrix to the SFUs in the joint scheduling group. When the joint scheduling group consists of the MFU performing joint scheduling and all scheduled SFUs, the MFU does not need to send the joint beamforming matrix to itself; it only needs to send the joint beamforming matrix to the SFUs in the joint scheduling group. When the joint scheduling group consists of the MFU performing joint scheduling with the highest authority, the MFU with lower authority that is subject to scheduling, and the scheduled SFUs, the MFU with the highest authority needs to send the generated joint beamforming matrix to both the lower-authority, subject-scheduled MFUs and the subject-scheduled SFUs.

[0138] Step M20: Under the control of the MFU, data transmission is performed using the joint beamforming matrix.

[0139] The joint beamforming matrix contains the signal transmission direction and gain coefficient of each functional unit in the joint scheduling group when transmitting data to the user terminal. This enables unified scheduling of wireless communication resources for each device in the FTTR system. Furthermore, the data transmission technology used by each functional unit in this embodiment is JT (Joint Transmission) technology. That is, this embodiment can use the joint beamforming matrix for joint data transmission through the functional units in the joint scheduling group. JT technology is an advanced wireless signal processing technology mainly used to improve the data rate for edge users of wireless networks and the overall network spectral efficiency. JT technology improves network coverage, enhances signal quality, and reduces interference by coordinating signal transmission and processing among multiple access points (APs), thereby enhancing user experience. The core of JT technology is coordination among multiple wireless devices that jointly serve the same user or user group, especially those users located in overlapping service areas of multiple wireless devices.

[0140] In this embodiment, the joint beamforming matrix of the joint scheduling group generated and transmitted by the MFU is received; under the control of the MFU, the joint beamforming matrix is ​​used for data transmission. Based on the communication resources of each functional unit in the joint scheduling group coordinated by the MCU, this application also generates a joint beamforming matrix so that any SFU in the joint scheduling group can transmit data according to the joint beamforming matrix, which can effectively reduce the impact of co-channel interference, thereby improving the communication quality of edge devices in the FTTR system.

[0141] Based on the fifth embodiment of this application, a sixth embodiment of this application is proposed. In the sixth embodiment of this application, content that is the same as or similar to that of the fifth embodiment described above can be referred to the above description and will not be repeated hereafter. Based on this, please refer to Figure 11, which is a flowchart illustrating the sixth embodiment of the device joint scheduling method of this application; as shown in Figure 11, the step of receiving the joint beamforming matrix of the joint scheduling group generated and sent by the MFU includes steps M201 to M203.

[0142] Step M201: Receive the measurement process start data sent by the MFU, and generate measurement response data based on the measurement process start data.

[0143] The measurement process start data is used by the MFU to inform the SFU to start the measurement process. The specific data interaction process can be seen in Figure 6. As shown in Figure 6, any SFU in the joint scheduling group receives the measurement process start data sent by the MFU through the air interface of WMCI, FMCI or other management channels, and generates measurement response data based on the measurement process start data to send the measurement process start data back to the MFU.

[0144] Step M202: Send the measurement response data to the MCU so that the MCU can generate the joint beamforming matrix of the joint scheduling group based on the measurement response data and preset service requirements.

[0145] Any SFU within the joint scheduling group sends measurement response data to the MCU via WMCI, FMCI, or other management channels. The MCU then generates the joint beamforming matrix for the joint scheduling group based on the measurement response data and preset service requirements. Furthermore, the steps for the MCU to generate the joint beamforming matrix based on the measurement response data and preset service requirements can be referred to the second embodiment described above, and will not be repeated here.

[0146] Step M203: Receive the joint beamforming matrix sent by the MCU.

[0147] In this embodiment, any SFU within the joint scheduling group receives the joint beamforming matrix sent by the MCU, and performs joint data transmission with other functional units within the joint scheduling group under the control of the MCU.

[0148] For example, the step of receiving the measurement process start data sent by the MFU and generating measurement response data based on the measurement process start data may include steps M2011 to M2013.

[0149] Step M2011: After clock synchronization with the MFU is completed, receive the measurement process start data sent by the MFU, and determine the measurement synchronization start time based on the measurement process start data.

[0150] The MFU and SFUs within the joint scheduling group need to synchronize their clocks. Before an SFU in the joint scheduling group sends a preset measurement frame to the STA at the other end, clock synchronization is required to determine a preset time. This ensures that any SFU in the joint scheduling group can uniformly send the preset measurement frame to the STA at the preset time. In this embodiment, clock synchronization between the MFU and SFU can use the 1588 protocol. After clock synchronization is complete, any SFU in the joint scheduling group receives the measurement process start data sent by the MFU and determines the measurement synchronization start time based on the measurement process start data. The measurement synchronization start time is used for that SFU and other SFUs in the joint scheduling group to simultaneously perform the measurement process.

[0151] Step M2012: Based on the measurement synchronization start time, a preset measurement frame is sent to the target STA to which the SFU is connected, so that the target STA can generate a response frame based on the measurement frame.

[0152] The SFU in the joint scheduling group sends a preset measurement frame to the target STA at the measurement synchronization start time. Referring to Figure 6, the target STA generates a response frame based on the measurement frame.

[0153] For example, the response frame includes a beamforming singular value decomposition matrix and / or a beamforming signal-to-noise ratio, and the measurement frame includes a null packet announcement response Sounding NDPA frame, which is used to obtain the beamforming singular value decomposition matrix and / or the beamforming signal-to-noise ratio through the target STA.

[0154] Sounding NDPA frames can directly obtain the required statistical parameters (including the beamforming singular value decomposition matrix and / or the beamforming signal-to-noise ratio) by enabling the SU / MU Sounding procedure. Furthermore, compared to methods that utilize the dissimilarity of uplink and downlink channels to extract the V matrix and SNR value from the uplink channel, enabling the MU sounding procedure can simultaneously obtain feedback information from multiple STAs, improving data transmission efficiency.

[0155] Step M2013: Receive the response frame sent by the target STA, and generate the measurement response data based on the response frame.

[0156] In this embodiment, after receiving the response frame returned by the target STA, any SFU in the joint scheduling group generates measurement response data based on the response frame and sends the measurement response data back to the MFU.

[0157] In this embodiment, after clock synchronization with the MFU, the system receives measurement process start data sent by the MFU and determines the measurement synchronization start time based on the measurement process start data. According to the measurement synchronization start time, a preset measurement frame is sent to the target STA connected to the SFU, so that the target STA can generate a response frame based on the measurement frame. The system receives the response frame sent by the target STA and generates the measurement response data based on the response frame. This embodiment enables communication between any SFU in the joint scheduling group and the target STA, and achieves rapid acquisition of beamforming parameters through measurement frames, improving the generation rate of the joint beamforming matrix and thus improving the data transmission efficiency of the FTTR system.

[0158] The above embodiments can be combined and implemented in a reasonable manner according to the actual situation, and this embodiment will not elaborate further.

[0159] This application also provides a device joint scheduling device, which is applied to the multifunctional unit (MFU) in the fiber optic home networking (FTTR) system. Please refer to Figure 12. The device joint scheduling device includes the following modules.

[0160] The joint beamforming module 10 is used to generate a joint beamforming matrix for a joint scheduling group and send the joint beamforming matrix to each functional unit in the joint scheduling group.

[0161] The joint scheduling module 20 is used to transmit data using the joint beamforming matrix through the functional units in the joint scheduling group.

[0162] For example, the joint beamforming module 10 is further configured to: determine the joint scheduling group.

[0163] For example, the joint beamforming module 10 is further configured to: determine a target SFU that meets preset constraints from at least one single-function unit (SFU) in the FTTR system; and determine the joint scheduling group corresponding to the target SFU.

[0164] For example, the joint beamforming module 10 is further configured to: in response to a joint scheduling request instruction, send preset statistical information query data to each SFU in the FTTR system, so that each SFU in the FTTR system can generate target statistical data based on the statistical information query data; receive the target statistical data sent by each SFU in the FTTR system; and determine the joint scheduling group corresponding to the target SFU based on the target statistical data and a preset joint scheduling group generation strategy.

[0167] For example, each functional unit in the joint scheduling group includes each SFU in the joint scheduling group. The joint beamforming module 10 is further configured to: in response to receiving air interface acquisition success data sent by any SFU in the joint scheduling group, notify each SFU in the joint scheduling group of measurement process start data, so that each SFU in the joint scheduling group can generate measurement response data according to the measurement process start data; receive the measurement response data sent by each SFU in the joint scheduling group, and generate the joint beamforming matrix of the joint scheduling group according to the measurement response data and preset service requirements; and send the joint beamforming matrix to each SFU in the joint scheduling group.

[0168] For example, the joint scheduling module 20 is further configured to: in response to receiving air interface acquisition success data sent by any SFU in the joint scheduling group, synchronize the pre-acquired data to be transmitted to each SFU in the joint scheduling group; send the data to be transmitted to the corresponding target wireless user terminal STA according to the joint beamforming matrix at a preset joint transmission time, and control each SFU in the joint scheduling group to send the data to be transmitted to the target STA according to the joint beamforming matrix.

[0169] For example, the joint scheduling module 20 is further configured to: in response to receiving air interface acquisition success data sent by any SFU in the joint scheduling group, synchronize the pre-acquired data to be transmitted to each SFU in the joint scheduling group; and control each SFU in the joint scheduling group to transmit the data to be transmitted to the corresponding target STA according to the joint beamforming matrix during a preset joint transmission time.

[0170] For example, the preset constraints include one or more of the following: historical joint beamforming matrix update constraints, SFU received signal strength constraints, SFU communication delay constraints, SFU communication transmission accuracy constraints, and SFU communication channel quantity constraints.

[0171] For example, the statistical information query data includes bandwidth data corresponding to each SFU in the FTTR system, and the bandwidth data includes current working bandwidth data and maximum working bandwidth data.

[0172] For example, the statistical information query data includes wireless communication status data between each SFU and its corresponding STA in the FTTR system. The wireless communication status data includes one or more of the following: signal strength data, average channel condition quantity data, spatial average signal-to-noise ratio data, and communication delay data.

[0173] For example, the measurement response data includes one or more of the following: beamforming singular value decomposition matrix, beamforming signal-to-noise ratio, beamforming channel matrix, and average message air interface transmission delay.

[0175] This application also provides a data transmission device, which is used in an SFU in an FTTR system. The SFU is any SFU in a joint scheduling group determined by an MFU in the FTTR system. Referring to Figure 13, the joint scheduling device includes the following modules.

[0176] The matrix receiving module 100 is used to receive the joint beamforming matrix of the joint scheduling group generated and transmitted by the MFU.

[0177] The data transmission module 200 is used to transmit data using the joint beamforming matrix under the control of the MFU.

[0178] For example, the matrix receiving module 100 is further configured to: receive measurement process start data sent by the MFU, and generate measurement response data according to the measurement process start data; send the measurement response data to the MCU, so that the MCU can generate the joint beamforming matrix of the joint scheduling group according to the measurement response data and preset service requirements; and receive the joint beamforming matrix sent by the MCU.
