Description

Communication method, communication equipment and communication system Technical Field

[0001] The present disclosure relates to the field of communication technology, and in particular to a communication method, communication equipment, and communication system. Background Art

[0002] Currently, Wi-Fi technology research focuses on Ultra High Reliability (UHR), with the goal of improving the reliability of Wireless Local Area Networks (WLAN) connections, reducing latency, improving manageability, increasing throughput at different signal-to-noise ratio (SNR) levels, and reducing device-level power consumption.

[0003] In UHR, when a device is performing Wi-Fi communications, services from other wireless communication media may also be present. This means that multiple communication media may coexist at the same time. Since multiple wireless communication media share device memory during communication, within a certain device cache (memory) size, the services from other wireless communication media may impact the transmission of Wi-Fi services, increasing communication latency. Therefore, a method is needed to specify the impact of services from other wireless communication media on Wi-Fi services.

[0103] FIG1 is a schematic diagram showing the architecture of a communication system according to an embodiment of the present disclosure.

[0104] As shown in Figure 1, a communication system 100 includes a first communication device 101 and a second communication device 102. The first communication device can be a station (STA) or an access point (AP); the second communication device can be a STA or an AP. For example, when the first communication device 101 is a STA, the second communication device 102 is an AP.

[0105] In some embodiments, the first communication device 101 and the second communication device 102 include, for example, a wireless communication chip, a wireless sensor, or a wireless communication terminal that supports WiFi communication. Optionally, the wireless communication terminal is, for example, at least one of a mobile phone, a wearable device, an Internet of Things device that supports WiFi communication, a car with WiFi communication, a smart car, a tablet computer, a computer with wireless transceiver function, a virtual reality (VR) terminal device, an augmented reality (AR) terminal device, a wireless terminal device in industrial control, a wireless terminal device in self-driving, a wireless terminal device in remote medical surgery, a wireless terminal device in a smart grid, a wireless terminal device in transportation safety, a wireless terminal device in a smart city, and a wireless terminal device in a smart home, but is not limited thereto.

[0106] Specifically, the first communication device 101 and the second communication device 102 may be terminal devices or network devices with wireless fidelity (WiFi) chips. Optionally, the first communication device 101 may support multiple WLAN standards such as 802.11ax, 802.11be, 802.11ac, 802.11n, 802.11g, 802.11b, 802.11a, 802.11bf, and 802.11bn, as well as support the next generation 802.11 protocol, but is not limited thereto.

[0107] In some embodiments, the first communication device 101 and the second communication device 102 can be access points for mobile terminals to enter a wired network. The AP is equivalent to a bridge connecting a wired network and a wireless network. Its main function is to connect various wireless network clients together and then connect the wireless network to the Ethernet. Specifically, the AP can be a terminal device or a network device with a wireless fidelity chip. Optionally, the AP can support multiple WLAN standards such as 802.11ax, 802.11be, 802.11ac, 802.11n, 802.11g, 802.11b and 802.11a, 802.11bf, 802.11bn, and support the next generation 802.11 protocol, but is not limited to this.

[0108] Optionally, in an embodiment of the present disclosure, the AP and STA may be devices supporting multiple connections, for example, they may be represented as a multi-connection access point device (AP MLD) and a multi-connection site device (Non-Access Point Multi-Link Device, Non-AP MLD), respectively; the AP MLD may represent an access point supporting multi-connection communication functions, and the non-AP MLD may represent a site supporting multi-connection communication functions.

[0109] It can be understood that the communication system described in the embodiment of the present disclosure is for the purpose of more clearly illustrating the technical solution of the embodiment of the present disclosure, and does not constitute a limitation on the technical solution proposed in the embodiment of the present disclosure. Ordinary technicians in this field can know that with the evolution of the system architecture and the emergence of new business scenarios, the technical solution proposed in the embodiment of the present disclosure is also applicable to similar technical problems.

[0110] The following embodiments of the present disclosure may be applied to the communication system 100 shown in FIG1 , or a portion thereof, but are not limited thereto. The entities shown in FIG1 are illustrative only. The communication system may include all or part of the entities shown in FIG1 , or may include other entities outside of FIG1 . The number and form of the entities are arbitrary, and the entities may be physical or virtual. The connection relationships between the entities are illustrative only. The entities may be connected or disconnected, and the connection may be in any manner, including direct or indirect, wired or wireless.

[0111] The various embodiments of the present disclosure can be applied to wireless local area networks (WLANs), such as those using the 802.11 series of protocols. In a WLAN, a Basic Service Set (BSS) is a fundamental component of a WLAN. A BSS network consists of STAs with certain associations within a specific coverage area. One scenario of association is that stations communicate directly with each other in an ad hoc network, which is called an Independent Basic Service Set (IBSS). Another more common scenario is that in a BSS network, there is only one central station dedicated to managing the BSS, called an AP, and all other STAs in the network are associated with it. Other stations in the BSS network that are not the central station are called terminals, also called non-AP STAs. Terminals and non-AP STAs are collectively referred to as STAs. When describing STAs, there is no need to distinguish between APs and non-AP STAs. In the same BSS network, due to factors such as distance and transmission power, a STA cannot detect other STAs that are farther away from it, and the two STAs are each other's hidden nodes.

[0112] FIG2 is an interactive diagram of a communication method according to an embodiment of the present disclosure. As shown in FIG2 , the method includes:

[0113] In step 201, the first communication device 101 determines a first radio frame; wherein the first radio frame includes first identification information, and the first identification information identifies that the first communication device 101 transmits communication technology parameters of the Wi-Fi communication service when the communication service of other wireless communication media coexists with the Wi-Fi communication service.

[0114] In WLAN communication scenarios, in addition to supporting Wi-Fi wireless communication media, STAs or APs may also support other wireless communication media, such as one or more of Bluetooth (Blue Tooth, BT) technology, New Radio (NR) technology, Long Time Evolution (LTE) technology, Ultra Wide Band (UWB) technology, and Zigbee technology. When a device is performing Wi-Fi communication, communication services on other communication media may be performed periodically. This, given a certain cache size on the device, can affect the data transmission size (e.g., MSDU parameter value size), data processing speed, BA mechanism, and MCS parameter value of the Wi-Fi communication service, increasing communication latency and hindering the transmission of communication services.

[0115] Optionally, before step 201, the first communication device acts as a data transmitter. Before sending a Wi-Fi data frame, the TXOP holder, after competing for a channel, sends a control frame to request the sending of the Wi-Fi data frame, such as a request to send (RTS) frame or a multi-user request to send (MU-RTS) frame; wherein a network allocation vector (NAV) is set in the RTS frame to indicate that the first communication device sends a data frame to the Wi-Fi data receiving end (second communication device) within the duration indicated by the NAV.

[0116] Among them, the first communication device may have other coexisting wireless communication media (hereinafter referred to as other communication services) that need to send or receive periodic services. In this case, the first communication device identifies in the first radio frame the communication technology parameters of the Wi-Fi communication service to be transmitted when the other communication service coexists with the wireless Wi-Fi communication service. For example, if the service parameters of the other communication service change, such as the period increases or decreases, the first communication device needs to change the communication technology parameters of the coexisting Wi-Fi communication service, and notifies the first communication device in the first radio frame.

[0117] Alternatively, the second communication device may have other communication services that need to be transmitted with the first communication device. For example, after receiving an RTS frame, the second communication device responds with a Clear To Send (CTS) frame to the first communication device after a SIFS interval. The CTS frame is used to indicate permission to transmit the data frame requested by the first communication device. The CTS frame may indicate that the second communication device has other co-existing wireless communication media that need to transmit or receive periodic services; or that there are periodic communication services on other wireless communication media, such as other co-existing wireless communication technologies, whose transmission time at least partially overlaps with the Wi-Fi service.

[0118] Among them, the communication services of other wireless communication media include one or more of the aforementioned BT technology, NR technology, LTE technology, UWB technology, and Zigbee technology.

[0119] If the CTS frame indicates that the second communication device has other communication services that need to be transmitted with the first communication device, or the first communication device has other coexisting wireless communication media that need to send or receive periodic services, the first communication device determines a first radio frame; wherein the first radio frame carries first identification information, and the first identification information indicates that the first communication device transmits communication technology parameters of the Wi-Fi communication service when the communication service of the other wireless communication medium coexists with the Wi-Fi communication service.

[0120] In one possible implementation, the communication technical parameters of the Wi-Fi communication service transmitted by the first communication device may change with the periodic changes of other communication services. For example, when the periodicity of the communication service parameters of other wireless communication media changes, such as when a communication service of another wireless communication medium is newly added, or when the periodicity of transmitting the communication service of another wireless communication medium is reduced, the first communication device determines a first radio frame, where the first radio frame includes first identification information, and the first identification information identifies that the first communication device can be used to transmit the communication technical parameters of the Wi-Fi communication service when the other communication services coexist with the Wi-Fi communication service.

[0121] Another possible implementation is that in a multi-link scenario, adding or removing a link by an Access Point Multi-Link Device (AP MLD) can also affect communication technical parameters. For example, when adding or removing a link, the AP MLD sends the changed communication technical parameters in an RTS frame to a non-Access Point Multi-Link Device (non-AP MLD).

[0122] It can be understood that, in the implementation of the present disclosure, "transmission" includes at least one of "sending" and "receiving".

[0123] In an embodiment of the present disclosure, when the communication services of other coexisting wireless communication media change periodically, a communication technology parameter that changes with the periodic changes in the communication services of the other coexisting wireless communication technologies is identified by a first radio frame, so that a second communication device is informed of the impact of the communication services of the other wireless communication media of the first communication device on the Wi-Fi communication services. This avoids the second communication device still sending data frames to the first communication device when the first communication device has periodic communication services of the other wireless communication media that need to be transmitted, resulting in a waste of signaling resources, thereby reducing system throughput, increasing communication latency, and hindering the transmission of communication services.

[0124] In some embodiments, the communication technology parameter includes at least one of the following:

[0125] An MPDU parameter, identifying a maximum value of MPDU data of a Wi-Fi communication service that can be buffered by the first communication device when transmitting the Wi-Fi communication service;

[0126] Because data frames transmitted via the Wi-Fi communication channel and data frames transmitted via other wireless communication media channels share the memory of the first communication device, the first communication device uses the MPDU parameter to identify the maximum value of MPDU data for the Wi-Fi communication service that can be cached by the first communication device when transmitting the Wi-Fi communication service. Specifically, if the first communication device supports multi-link communication and there are communication services of other wireless communication media on the first link of the multi-link, the first communication device uses the MPDU parameter to identify the maximum value of MPDU data for the Wi-Fi communication service that can be cached by the first communication device when transmitting the Wi-Fi communication service on the second link. It can be understood that the first communication device provides the second communication device with the maximum cache value of MPDU data for the Wi-Fi communication service, enabling the second communication device to better manage and schedule the data transmission of the Wi-Fi communication service, thereby helping to reduce data loss in a multi-link communication environment and improve data transmission reliability. Furthermore, the second communication device uses the MPDU parameter to understand the cache capacity of the first communication device, enabling the second communication device to more intelligently manage multi-link communication, facilitating more balanced data transmission across multiple communication links, improving the utilization efficiency of multi-link communication, and ensuring that each link is fully utilized.

[0127] An A-MSDU parameter, which identifies the maximum length of a block acknowledgment (BA) that can be fed back when the first communication device transmits the Wi-Fi communication service, and the number of media access control service data units (MSDUs) that can be buffered;

[0128] The first communication device uses the A-MSDU parameter to identify the maximum Block Acknowledgement (BA) length that can be fed back and the number of Media Access Control Service Data Units (MSDUs) that can be buffered for the Wi-Fi communication service transmitted by the first communication device over the second link. It should be noted that by transmitting the A-MSDU parameters, including the maximum BA length and the number of buffered MSDUs, to the second communication device, the first communication device enables the second communication device to more efficiently manage Wi-Fi data transmission, thereby improving communication efficiency, reducing acknowledgment overhead during communication, and thereby accelerating data transmission.

[0129] A BW parameter, identifying a communication bandwidth for transmitting the Wi-Fi communication service by the first communication device;

[0130] The first communication device uses the BW parameter to identify the communication bandwidth used by the first communication device to transmit the Wi-Fi communication service under the second link. It should be noted that by transmitting the BW parameter information of the Wi-Fi communication service to the first communication device, the second communication device can more accurately understand the communication needs of the first communication device, thereby more effectively allocating resources, avoiding resource waste, and improving the utilization efficiency of communication resources.

[0131] An MCS parameter, identifying a maximum MCS value for transmitting the Wi-Fi communication service by the first communication device;

[0132] The first communication device identifies, by an MCS parameter, a maximum MCS value for transmitting the Wi-Fi communication service on the second link. It should be noted that the first communication device can transmit more data in the same amount of time by using a higher MCS value based on its internal processing speed, thereby reducing communication latency.

[0133] The PPDU duration parameter identifies the maximum PPDU duration for the first communication device to transmit the Wi-Fi communication service.

[0134] The first communication device uses the PPDU duration parameter to identify the maximum PPDU duration for transmitting Wi-Fi communication services on the second link. It should be noted that transmitting the PPDU duration parameter helps the system more accurately control the physical layer timing of each Wi-Fi communication service, thereby improving spectrum utilization and ensuring that Wi-Fi communication occupies spectrum resources more efficiently.

[0135] In some embodiments, when the cache of the first communication device is limited, the communication technology parameters transmitted by the first communication device to the second communication device further include at least one of the following:

[0136] A BA feedback mechanism parameter, indicating whether the BA feedback mechanism is enabled or disabled when the first communication device transmits a Wi-Fi communication service;

[0137] The first communication device can flexibly choose whether to use this mechanism based on actual communication needs to balance latency and efficiency. For example, if the device's memory, cache capacity, or data processing capabilities decrease, the BA feedback mechanism can be disabled; conversely, if the device's memory, cache capacity, or data processing capabilities increase, the BA feedback mechanism can be enabled.

[0138] The TID parameter indicates whether the coexistence mechanism of the TID in the A-MPDU is started or disabled when the first communication device transmits the Wi-Fi communication service.

[0139] For example, when the device memory, cache capacity, or data processing capability decreases, the coexistence mechanism of TID in A-MPDU can be disabled; conversely, when the device memory, cache capacity, or data processing capability increases, the coexistence mechanism of TID in A-MPDU can be enabled.

[0140] Optionally, the communication technology parameters may be carried in the A-control field of the first radio frame.

[0141] In some embodiments, the communication service of the other wireless communication medium is a periodic service, and the first wireless frame is an action frame;

[0142] The action frame includes a first identification field, and the first identification field carries the first identification information.

[0143] As shown in Figure 3, if the communication service of the other wireless communication medium is a periodic service, then after completing the periodic information exchange, it can interact with the second communication device and define a separate action frame. The frame structure of the action frame includes a frame control field, a duration field, a receiver address field, a transmitter address field, and a first identifier field. The first communication device carries the same information as the A-control field of the RTS frame in the first identifier field of the action frame.

[0144] Step 202: The first communication device 101 sends the first radio frame.

[0145] In some embodiments, when the cycle of the communication service of other wireless communication media changes, such as when a new communication service of other wireless communication media is added or when the cycle of transmitting the communication service of other wireless communication media decreases, the first communication device sends an RTS frame. For example, in a multi-link scenario, the first communication device sends an RTS frame under the first link of Wi-Fi communication with the second communication device. The embodiments of the present disclosure send RTS frames in a timely manner to report the dynamic changes in the communication service cycle of other communication media, so that the second communication device can adjust the Wi-Fi communication strategy in a timely manner to maximize the network throughput, thereby facilitating efficient multi-link communication.

[0146] Step 203: The second communication device 102 receives the first wireless frame. The first communication device 101 transmits Wi-Fi communication services on the second link according to the communication technology parameters when there are communication services of other wireless communication media on the first link.

[0147] The second communication device can dynamically select the link most suitable for transmitting Wi-Fi communication services based on the communication technology parameters in the received RTS frame, so as to reduce interference with other wireless communication media and improve the quality and reliability of Wi-Fi communication.
