Description

Technical Field

[0001] This application relates to the field of communication technology, and in particular to a communication method and apparatus. Background Technology

[0002] In a fiber-to-the-room (FTTR) network, the main FTTR unit (MFU) can connect to one or more sub-FTTR units (SFUs). The MFU can run scheduling based on the buffered information reported by each SFU and send the scheduling results to each SFU. The SFU runs its local scheduling process based on the received scheduling results and prepares for air interface transmission based on the local scheduling results.

[0003] However, in the above method, the preparation delay before each SFU transmits over the air interface is relatively large, and the running time of the scheduling process corresponding to each SFU may be different, which affects the concurrent performance of the communication system. Summary of the Invention

[0004] This application provides a communication method and apparatus that can reduce the preparation delay of each first device before it performs air interface transmission, and at the same time, can ensure that each first device can transmit synchronously in space, thereby improving the spatial multiplexing performance of the communication system.

[0005] Firstly, this application provides a communication method that can be executed by a first device. Unless otherwise specified, "first device" in this application can refer to the first device itself, a component within the first device (e.g., a processor, chip, or chip system), or a logic module or software capable of implementing all or part of the functions of the first device. The method includes: sending a scheduling request to a second device; the scheduling request including a first scheduling result, which is a scheduling result obtained by the first device through local pre-scheduling; receiving a scheduling instruction from the second device, and transmitting the instruction over the air interface according to the scheduling instruction, the scheduling instruction being determined based on the first scheduling result.

[0006] Based on the first aspect, each first device can perform local pre-scheduling first, and then the second device performs centralized scheduling based on the scheduling results of each first device. After receiving the scheduling instruction sent by the second device based on the centralized scheduling, each first device can form a scheduling result and start air interface transmission, reducing latency. At the same time, it can avoid the inability of each first device to synchronize space-division transmission due to different execution times of the local scheduling process. Each first device in this application can start air interface transmission after receiving the scheduling instruction sent by the second device, which can ensure that each first device can synchronize space-division transmission and improve the spatial multiplexing performance of the communication system.

[0007] In one possible design, the first scheduling result includes one or more of the following: scheduling number, first device number, number of users, user list, minimum transmission duration, scheduling request duration, service identifier (TID) number, or TID delay.

[0008] Based on this possible design, the first scheduling result sent by the first device to the second device may include one or more of the above parameters, so that the second device can determine the scheduling instruction more accurately based on the above one or more parameters, thereby improving communication performance.

[0009] In one possible design, the scheduling instruction includes one or more of the following: scheduling number, data frame transmission time, or data frame transmission duration.

[0010] Based on this possible design, and based on the aforementioned data frame transmission time, each first device can synchronously send data frames (or messages) to each terminal device, improving the spatial multiplexing performance of the communication system. Furthermore, when determining the data frame transmission duration, the second device can determine it based on the minimum value of multiple minimum transmission durations among multiple first scheduling results, such as a data frame transmission duration greater than or equal to the minimum value of these multiple minimum transmission durations.

[0011] In one possible design, the method further includes: feeding back transmission result information to the second device; wherein the transmission result information includes one or more of the following: scheduling number, transmission result, number of transmitted Protocol Data Units (MPDUs), transmission duration, or packet error rate.

[0012] Based on this possible design, the first device can also send transmission result information back to the second device, so that the second device can adjust the scheduling instructions sent to the first device according to the transmission result information, thereby improving communication performance.

[0013] Secondly, this application provides a communication method that can be executed by a second device. Unless otherwise specified, "second device" in this application can refer to the second device itself, a component within the second device (e.g., a processor, chip, or chip system), or a logic module or software capable of implementing all or part of the functions of the second device. The method includes: receiving a scheduling request from a first device, the scheduling request including a first scheduling result, which is a scheduling result obtained by the first device through local pre-scheduling; sending a scheduling instruction to the first device; wherein the scheduling instruction is determined based on the first scheduling result; and the scheduling instruction is used by the first device for over-the-air transmission.

[0014] Based on the second aspect, each first device can first perform local pre-scheduling, and then the second device performs centralized scheduling based on the first scheduling results of each first device. After receiving the scheduling instruction sent by the second device based on the centralized scheduling, each first device can form a scheduling result and start air interface transmission, reducing latency. At the same time, it can avoid the inability of each first device to synchronize space division transmission due to different execution times of the local scheduling process. Each first device in this application can start air interface transmission after receiving the scheduling instruction sent by the second device, which can ensure that each first device can synchronize space division transmission and improve the spatial multiplexing performance of the communication system.

[0015] In one possible design, the first scheduling result includes one or more of the following: scheduling number, first device number, number of users, user list, minimum transmission duration, scheduling request duration, service identifier (TID) number, or TID delay.

[0016] Based on this possible design, the first scheduling result sent by the first device to the second device may include one or more of the above parameters, so that the second device can determine the scheduling instruction more accurately based on the above one or more parameters, thereby improving communication performance.

[0017] In one possible design, the scheduling instruction includes one or more of the following: scheduling number, data frame transmission time, or data frame transmission duration.

[0018] Based on this possible design, and based on the aforementioned data frame transmission time, each first device can synchronously send data frames (or messages) to each terminal device, improving the spatial multiplexing performance of the communication system. Furthermore, when determining the data frame transmission duration, the second device can determine it based on the minimum value of multiple minimum transmission durations among multiple first scheduling results, such as a data frame transmission duration greater than or equal to the minimum value of these multiple minimum transmission durations.

[0019] In one possible design, the method further includes: receiving transmission result information from a first device; wherein the transmission result information includes one or more of the following: scheduling number, transmission result, number of transmitted Protocol Data Units (MPDUs), transmission duration, or packet error rate.

[0020] Based on this possible design, the first device can also send transmission result information back to the second device, so that the second device can adjust the scheduling instructions sent to the first device according to the transmission result information, thereby improving communication performance.

[0021] Thirdly, this application provides a communication device that can be applied to the first device described in the first aspect to realize the functions performed by the first device.

The transceiver module can independently complete the following transceiver operations, or it can cooperate with the processing module to complete the following transceiver operations; correspondingly, the processing module can independently complete the following processing operations, or it can cooperate with the transceiver module to complete the following processing operations, without limitation.

[0022] For example, the transceiver module is used to send a scheduling request to the second device; the scheduling request includes a first scheduling result, which is a scheduling result obtained by the first device through local pre-scheduling; the transceiver module is also used to receive a scheduling instruction from the second device and perform air interface transmission according to the scheduling instruction, which is determined based on the first scheduling result.

[0043] Figure 7 This is a structural diagram of a communication device provided in an embodiment of this application. Detailed Implementation

[0044] The communication method provided in this application embodiment can be applied to fiber-to-the-room (FTTR) networking scenarios.

[0045] For example, such as Figure 1As shown, an FTTR networking scenario can include a main FTTR unit (MFU) and a sub FTTR unit (SFU). The operator's network can communicate with the MFU via fiber to the home (FTTH). The MFU can connect to one or more SFUs via an optical link (such as fiber optic cable). For example, the MFU and SFU can communicate via xPON protocols such as Ethernet Passive Optical Network (EPON) or Gigabit Passive Optical Network (GPON), without limitation. The SFU and terminal equipment can communicate via wireless local area networks (WLAN) technology.

[0046] Figure 1 The MFU in this context can be a device that supports relevant standards of the Institute of Electrical and Electronics Engineers (IEEE) and can communicate with one or more SFUs via an optical link. For example, the MFU can receive optical signals converted from uplink digital signals sent by the SFU through the uplink transmission channel of the optical link, and send optical signals converted from downlink digital signals to the SFU through the downlink transmission channel of the optical link.

[0047] The relevant IEEE standards can include: 802.11a / b / g, 802.11n, 802.11ac, 802.11ax, 802.11be, 802.11bn (Ultra High Reliability, UHR) / Wi-Fi 8, 802.11ad, 802.11ay, 802.11bf (sensing), Ultra Wide Bandwidth (UWB), and 802.15, etc., without restriction. Regarding bandwidth configuration, channel bundling was introduced starting with 802.11n, allowing multiple 20MHz channels to be bundled together to achieve greater bandwidth and higher transmission rates. Starting with 802.11ac, a maximum bandwidth of 160MHz can be provided. The 802.11ax standard supports the following bandwidth configurations: 20MHz, 40MHz, 80MHz, 160MHz, and 80+80MHz. The 802.11be standard also supports a 320MHz bandwidth configuration.

[0048] For example, an MFU can be a device with a Wi-Fi chip, such as a network device, communication server, router, switch, bridge, or computer. An MFU can also serve as an access point for mobile users to access a wired network, primarily deployed in homes, buildings, and campuses, with a typical coverage radius of tens to hundreds of meters. Of course, it can also be deployed outdoors. An MFU acts as a bridge connecting wired and wireless networks, its main function being to connect various wireless network clients together and then connect the wireless network to the Ethernet.

[0049] Figure 1 The SFU in this context can be a device that supports relevant IEEE standards and can communicate with terminal devices based on Wi-Fi technology. The SFU also communicates with the MFU via an optical link. The SFU can include one or more antennas, which can convert digital signals from these antennas into optical signals and transmit them to the MFU via the uplink transmission channel of the optical link. Alternatively, the SFU can receive optical signals converted from downlink digital signals transmitted by the MFU via the downlink transmission channel of the optical link, either through one or more antennas.

[0050] For example, an SFU can be a device with a Wi-Fi chip, such as a network device, communication server, router, switch, bridge, or computer. An SFU can also serve as an access point (AP) for mobile users to access a wired network, primarily deployed in homes, buildings, and campuses, with a typical coverage radius of tens to hundreds of meters. Of course, it can also be deployed outdoors. An SFU acts as a bridge connecting wired and wireless networks, its main function being to connect various wireless network clients together and then connect the wireless network to the Ethernet.

[0051] Figure 1 The terminal device in the process can be a device that supports relevant IEEE standards and can establish a communication connection with the SFU based on Wi-Fi technology, such as sending physical frames to the SFU based on radio frequency analog signals (or wireless signals, wireless radio frequency analog signals, wireless analog signals, etc.).

[0052] For example, terminal devices can be station (STA) equipment, wireless communication chips, wireless sensors (such as temperature and humidity sensors), wireless communication terminals, communication servers, routers, switches, bridges, computers, etc. For instance, terminal devices can be mobile phones supporting Wi-Fi communication, tablet computers supporting Wi-Fi communication, set-top boxes supporting Wi-Fi communication, smart home appliances supporting Wi-Fi communication, smart wearable devices supporting Wi-Fi communication, in-vehicle communication devices supporting Wi-Fi communication, computers supporting Wi-Fi communication, cameras supporting Wi-Fi communication, robots supporting Wi-Fi communication, office equipment supporting Wi-Fi communication, etc., without limitation.

[0053] In the aforementioned FTTR networking process, the MFU can run scheduling based on the cached information reported by each SFU and send the scheduling results to each SFU. The SFU runs its local scheduling process based on the received scheduling results and prepares for air interface transmission based on the local scheduling results, that is, prepares to send messages to the terminal devices.

[0054] However, in the above method, after the MFU sends the scheduling result to the SFU, it still needs to wait for the SFU to complete its local scheduling before the SFU can start air interface transmission, which leads to increased latency.

[0055] In addition, spatial reuse requires that each SFU send messages synchronously. However, the execution time of the local scheduling process corresponding to each SFU is uncertain and may be different, which makes it impossible to guarantee that each SFU can use spatial reuse synchronously, thus affecting the spatial reuse performance of the communication system.

[0056] To address the aforementioned technical problems, embodiments of this application provide a communication method in which a first device can send a scheduling request to a second device. The scheduling request includes a first scheduling result, which is a scheduling result obtained by the first device through local pre-scheduling. The first device can receive a scheduling instruction from the second device and perform air interface transmission according to the scheduling instruction; the scheduling instruction is determined based on the first scheduling result.

[0057] In this embodiment, each first device can perform local pre-scheduling first, and then the second device performs centralized scheduling based on the first scheduling results of each first device. After receiving the scheduling instruction sent by the second device based on centralized scheduling, each first device can form a scheduling result and start air interface transmission, reducing latency. Simultaneously, it avoids the inability of each first device to synchronize space-division transmission due to different execution times of their local scheduling processes. Each first device in this application can start air interface transmission after receiving the scheduling instruction sent by the second device, ensuring that each first device can synchronize space-division transmission and improving the spatial multiplexing performance of the communication system.

[0058] The following is combined Figure 1 The communication system shown refers to the following Figure 2 The communication method provided in the embodiments of this application is described below, wherein the first device can be Figure 1 In any SFU of the communication system shown, the second device can be Figure 1 In any MFU of the communication system shown, the terminal device can be Figure 1 Any terminal device in the communication system shown.

[0059] It is understood that the processing performed by a single execution entity (first device, second device, or terminal device) shown in the embodiments of this application can also be divided into multiple execution entities, which can be logically and / or physically separated, without limitation. Furthermore, the message names or parameter names in the messages exchanged between the various devices in the embodiments of this application are merely examples; other names may be used in specific implementations without limitation. Actions, terms, etc., involved in the various embodiments of this application can be referenced mutually without limitation.

[0060] Figure 2 A flowchart of a communication method provided in an embodiment of this application is shown below. Figure 2 As shown, the method may include:

[0061] Step 201: The first device sends a scheduling request to the second device; correspondingly, the second device receives the scheduling request from the first device.

[0062] The scheduling request is used to request the second device to schedule the first device. The scheduling request may include a first scheduling result, which is the scheduling result obtained by the first device through local pre-scheduling.

[0063] The first device can run a local pre-scheduling algorithm based on local business information to achieve local pre-scheduling and obtain a first scheduling result, which can also be called a pre-scheduling result.

[0064] For example, local service information may include one or more of the following: the number of terminal devices connected to the first device, cache information, latency, speed, and other information.

[0065] For example, the first scheduling result may include one or more of the following: scheduling number, first device number, number of users, user list, minimum transmission duration, scheduling request duration, traffic ID (TID) number, or TID delay.

[0066] The bytes occupied by each parameter in the first scheduling result and their descriptions are shown in Table 1 below:

[0067] Table 1

[0068]

[0069] It is understood that the aforementioned minimum transmission duration is used to assist the second device in determining the parameter of the data frame transmission duration of the scheduling instruction in step 202 below. That is, when the second device determines the data frame transmission duration, the data frame transmission duration must be greater than or equal to the minimum value of the multiple minimum transmission durations among the multiple first scheduling results.

[0070] In addition, the scheduling request duration parameter can be information that directly indicates the scheduling request duration or information that indirectly indicates the scheduling request duration, without restriction.

[0071] For example, the scheduling request duration can be a specific duration. Alternatively, the duration can be pre-divided into several segments, with the scheduling request duration indicating one of these segments to indirectly obtain the scheduling request duration. Alternatively, the scheduling request duration can also be the end timestamp of the time slot acquisition.

[0072] Step 202: The second device sends a scheduling instruction to the first device according to the scheduling request; correspondingly, the first device receives the scheduling instruction from the second device.

[0073] The scheduling instruction can be determined based on the first scheduling result.

[0074] The second device can communicate with one or more first devices. Each of the one or more first devices can send a first scheduling result to the second device in the manner described in step 201 above. The second device performs centralized scheduling on the one or more first devices based on the received one or more first scheduling results and sends scheduling instructions to the one or more first devices.

[0075] For example, a scheduling instruction may include one or more of the following: a scheduling number, a data frame transmission time, or a data frame transmission duration.

[0076] The bytes occupied by each parameter in the scheduling instruction and its description are shown in Table 2 below:

[0077] Table 2

[0078] content byte describe Dispatch number 1 Corresponding to the pre-scheduled scheduling number Data frame transmission time 4 Used to indicate the time at which data frame transmission begins, in microseconds (µs). Data frame transmission duration 2 Used to indicate the duration of data transmission

[0079] It is understandable that, based on the aforementioned data frame transmission time, each first device can synchronously send data frames (or messages) to each terminal device, thereby improving the spatial multiplexing performance of the communication system.

[0080] In addition, when determining the data frame transmission duration, the second device can determine it based on the minimum value of multiple minimum transmission durations among multiple first scheduling results, such as the data frame transmission duration being greater than or equal to the minimum value of the multiple minimum transmission durations.

[0081] Step 203: The first device transmits over the air interface according to the scheduling instructions.

[0082] The first device can generate a scheduling result after receiving the scheduling instruction and start air interface transmission, that is, send a message (or data frame) to the terminal device.

[0083] Based on the above Figure 2 The method described herein allows each first device to perform local pre-scheduling, followed by centralized scheduling by a second device based on the scheduling results of each first device. Upon receiving the scheduling instruction sent by the second device based on the centralized scheduling, each first device can generate a scheduling result and initiate air interface transmission, reducing latency. Simultaneously, it avoids the inability of different first devices to synchronize space-division transmission due to varying execution times of their local scheduling processes. In this application, each first device can initiate air interface transmission upon receiving the scheduling instruction from the second device, ensuring synchronized space-division transmission and improving the spatial multiplexing performance of the communication system.

[0084] Optionally, based on the above Figure 2 The method shown is as follows: Figure 3 As shown in step 204, the first device can also send the transmission result information of the first device back to the second device. This transmission result information can also be called transmission result feedback information.

[0085] For example, the transmission result information may include one or more of the following: scheduling number, transmission result, number of transmitted message protocol data units (MPDUs), transmission duration, or packet error rate.

[0086] The bytes occupied by each parameter in the transmission result information and their descriptions are shown in Table 3 below:

[0087] Table 3

[0088]

[0089] It is understandable that the MPDU mentioned above can also be understood as a message.

[0090] Optional, such as Figure 3 As shown in step 204a, after receiving the message sent by the first device, the terminal device can send a block ACK (BA) frame to the first device. The first device determines the aforementioned transmission result information based on the received BA frame.

[0091] Based on the above description, optionally, each of the first and second devices performs the above... Figure 2 Before the method shown, initialization and synchronization can also be performed.

[0092] For example, such as Figure 4 As shown, taking the first device as SFU1, SFU2, ..., SFUN and the second device as MFU as an example, SFU1, SFU2, ..., SFUN can perform local pre-scheduling based on step 201 above, obtain the first scheduling result corresponding to each SFU, and send a scheduling request to the MFU. The MFU performs centralized scheduling based on the first scheduling result corresponding to each SFU and issues scheduling instructions to each SFU. Each SFU forms a scheduling result based on the scheduling instructions sent by the MFU and starts air interface transmission.

[0093] Optionally, each SFU can also send the transmission results information of each SFU back to the MFU.

[0094] Optionally, each SFU can also initialize and synchronize with the MFU before performing local pre-scheduling.

[0098] This application embodiment can divide each device into functional modules according to the above method example. For example, each function can be divided into a separate functional module, or two or more functions can be integrated into one processing module. The integrated module can be implemented in hardware or as a software functional module. It should be noted that the module division in this application embodiment is illustrative and only represents one logical functional division.
