[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 communication, services on other wireless communication media may also be present. In other words, 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 communication services of other wireless communication media may affect the transmission of Wi-Fi communication services, increasing communication latency. Therefore, a method is needed to prevent the communication services of other wireless communication media from affecting Wi-Fi communication services.

[0120] FIG1 is a schematic diagram showing the architecture of a communication system according to an embodiment of the present disclosure.

[0121] As shown in FIG1 , a communication system 100 includes a first communication device 101 (which may be a Station, STA or Access Point, AP) and a second communication device 102 (which may be a Station, STA or Access Point, AP).

[0122] In some embodiments, the first communication device 101 and the second communication device 102 may be, for example, a wireless communication chip, a wireless sensor, or a wireless communication terminal that supports Wi-Fi communication. Optionally, the wireless communication terminal may be, for example, a mobile phone, a wearable device, an Internet of Things device that supports Wi-Fi communication, a car with Wi-Fi 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, or a wireless terminal device in a smart home, but is not limited thereto.

[0123] Specifically, the first communication device 101 and the second communication device 102 may be terminal devices or network devices with a wireless fidelity (Wi-Fi) chip. Optionally, the TXOP responder 101 and the TXOP initiator 102 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 are not limited thereto.

[0124] 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.

[0125] 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.

[0126] 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.

[0127] 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.

[0128] 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 station devices with some association 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 access point, 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 distance, transmission power, and other factors, a STA cannot detect other STAs that are farther away from it, and the two STAs are each other's hidden nodes.

[0129] FIG2 is an interactive diagram of a communication method according to an embodiment of the present disclosure. As shown in FIG2 , the method includes:

[0130] In step 201, the first communication device 101 determines a first wireless frame; wherein the first wireless frame includes first identification information, and the first identification information identifies that the first communication device 101 has a communication service of other wireless communication media, and releases or stops the block acknowledgment (Block ACK) mechanism established between the first communication device 101 and the second communication device 102.

[0131] With the development of wireless communication technology, the integration of terminal devices is becoming increasingly higher. A terminal device often supports multiple wireless communication protocols, integrates multiple wireless communication modules, or accesses multiple wireless networks at the same time. For example, in a WLAN communication scenario, in addition to supporting Wi-Fi wireless communication media, a STA or AP may also support other wireless communication media, such as Bluetooth (Blue Tooth, BT) technology, New Radio (New Radio, NR) technology, Long Time Evolution (Long Time Evolution, LTE) technology, Ultra Wide Band (UWB) technology, Zigbee technology, and Global Navigation Satellite System (GNSS) technology. However, when the communication frequency bands of different communication systems are adjacent, the transmission operation of one communication system may interfere with the reception operation of another communication system. For example, when Wi-Fi wireless communication is adjacent to frequency bands such as Long Term Evolution Wideband 40 (LTW Band 40) and Long Term Evolution Wideband 7 (LTW Band 7), and the frequency components fall within the adjacent channel operating bands, communication interference of the adjacent channels will be caused. In addition, when multiple wireless communication modules coexist, the physical distance between the radio frequency (RF) modules of each communication module is small. When working simultaneously, the communication systems interfere with each other, affecting the transmission and reception of each communication module.

[0132] For example, both Wi-Fi and BT operate in the 2.4 GHz frequency band, and due to factors such as device miniaturization and cost, the Wi-Fi and BT modules in most communication devices share a common antenna. Therefore, Wi-Fi and BT communications, whether within a single node or between multiple nodes, interfere with each other in the time domain. Furthermore, as the bandwidth of wireless communication systems increases and becomes increasingly abundant, interference between multiple wireless communication media within a device becomes increasingly severe, reducing the reliability of data transmission between devices.

[0133] In Wi-Fi communications, devices use a Block Acknowledgement (BA) mechanism to transmit data frames. The BA mechanism is a technology used to improve Wi-Fi data transmission efficiency by allowing the receiver to acknowledge the receipt of multiple data frames at once. For example, after receiving multiple data frames, the receiver sends a Block Acknowledgement (BA) frame to the transmitter. The transmitter uses the Block Acknowledgement (BA) frame to determine which data frames have been successfully received and which need to be retransmitted. Therefore, establishing a BA mechanism between devices can reduce the transmission of control frames on the wireless channel, thereby improving system throughput.

[0134] When a device is performing Wi-Fi communication, the communication services of other communication media will affect the BA mechanism of the Wi-Fi communication service. For example, when an access point or site device has in-device coexistence (IDC) activity, the communication services of other communication media will cause data loss and waste of communication resources. When an access point or site device has in-device coexistence activity and stops sending data, if the receiving end still maintains the receiving state, then because the sending end has stopped data transmission, the receiving end may mistakenly believe that the data reception has failed. This situation may cause the receiving end to trigger a retransmission mechanism. On the other hand, the receiving end being in the receiving state for a long time will also increase energy consumption overhead. It can be understood that in the embodiment of the present disclosure, the in-device coexistence activity includes, for example, communication services of other wireless communication media.

[0135] Optionally, before step 201, the first communications device, as the initiator or recipient of a request to establish a BA mechanism, establishes a BA mechanism with the second communications device. For example, when the first communications device is the initiator of a request to establish a BA mechanism, it sends a BA request frame to the second communications device, requesting the establishment of a BA session. After receiving the BA request frame, the second communications device, as the recipient of a request to establish a BA mechanism, acknowledges the receipt and establishes the BA session.

[0136] In some embodiments, a first communication device and a second communication device negotiate to establish a BA mechanism, and there is in-device coexistence activity during the process of sending or receiving data on the first communication device. The first communication device determines a first wireless frame, and the first wireless frame includes first identification information. The first identification information is used to inform the second communication device of the interference problem caused by the in-device coexistence activity of the first communication device, to release or stop the BA mechanism established between the devices, and to inform it of relevant information about the in-device coexistence activity.

[0137] Step 202: The first communication device sends the first radio frame.

[0138] In some embodiments, a first communication device sends a first wireless frame, which includes first identification information. The first identification information is used to inform the second communication device that there is intra-device coexistence activity within the first communication device, which may cause interference. Therefore, the BA mechanism established between the two devices is released or stopped, and the relevant information about the intra-device coexistence activity is informed.

[0139] In this way, if a block acknowledgment mechanism has been established between the first communication device and the second communication device, then during the data block transmission process, interference is caused by the in-device coexistence activity between the first communication device and the second communication device, which will cause data loss during the data block transmission process. The device with in-device coexistence activity (the first communication device) sends a first wireless frame to another communication device (the second communication device) to report the in-device coexistence activity of the first communication device to the second communication device. The second communication device chooses whether to continue the transmission of the data block based on the in-device coexistence activity of the first communication device, and determines whether to release or stop the Block ACK transmission mechanism or the time to retransmit the data. The embodiment of the present disclosure can effectively avoid the interference between communication devices due to in-device coexistence activities, resulting in data packet loss and waste of communication resources, and further improve the reliability and efficiency of transmission.

[0140] In some embodiments, the first radio frame further includes at least one of the following:

[0141] second identification information, identifying duration information of the first communication device transmitting the communication service;

[0142] The third identification information identifies the start time information of the first communication device transmitting the communication service.

[0143] The information related to the intra-device coexistence activity of the first communication device is identified by the second identification information and / or third identification information of the first radio frame. The second identification information identifies the duration of the transmission of the communication service by the first communication device, and the third identification information identifies the start time of the transmission of the communication service by the first communication device.

[0144] In some embodiments, the method further comprises at least one of the following:

[0145] When the first radio frame includes the third identification information and the parameter value of the third identification information is not the first parameter value, it identifies the start time point of the first communication device transmitting the communication service;

[0146] The first wireless frame includes the third identification information, and the third identification information is set to the first parameter value; or the first wireless frame does not include the third identification information, which indicates that the first communication device has started or is about to start transmitting the communication service.

[0147] Among them, if the first wireless frame includes the third identification information, and the parameter value of the third identification information is not the first parameter value, for example, the first parameter value is "0", then when the parameter value of the third identification information is not 0, it identifies the starting time point of the first communication device transmitting the communication service.

[0148] In some embodiments, if the first wireless frame includes the third identification information, and the third identification information is set to the first parameter value, for example, set to 0; or the first wireless frame does not include the third identification information, it indicates that the first communication device has started or is about to start transmitting the communication service.

[0149] For example, if the first wireless frame includes third identification information and the parameter value of the third identification information is "0", then the third identification information indicates that the first communication device has started or is about to start transmitting the communication service; or, if the first wireless frame does not include the third identification information, then it indicates that the first communication device has started or is about to start transmitting the communication service.

[0150] In some embodiments, the first radio frame includes a Delete BA (DEL BA) frame, and the first identification information includes a Reason Code field. The Reason Code field is set to a second parameter value, identifying that the first communication device has the communication service, and instructing the second communication device receiving the first radio frame to release or stop the Block Ack mechanism established between the first communication device and the first communication device. For example, if the parameter value of the Reason Code field is set to "72", it indicates that the first communication device has a communication service of other communication media, and instructs the second communication device receiving the first radio frame to release or stop the Block Ack mechanism established between the first communication device and the first communication device.

[0151] In some embodiments, the first radio frame includes a first element, which includes one or more first fields, as shown in Table 1 below.

[0152] Table 1:

[0153] In some embodiments, as shown in FIG3 , the first field includes a second subfield (IDC Activities Parameter). The second subfield includes at least one of a first information field (IDC Activity Duration) and a second information field (IDC Activity Start Time). The first information field carries second identification information, and the second information field carries third identification information. The first field also includes a first subfield, and the first subfield includes a first identifier. The first identifier identifies whether the first field is the last first field included in the first element, that is, identifies the number of first fields included in the first element in an implicit manner. For example, the first identifier is set to "1", indicating that the first field is the last first subfield included in the first element; the first identifier is set to "0", indicating that the first field also contains other first subfields until the first identifier in the subsequent first field is "0".

[0154] Step 203: The second communication device 102 receives the first radio frame, and releases or stops the Block ACK mechanism with the first communication device 101 according to the first radio frame.

[0155] After receiving the first wireless frame, the second communication device performs different operations according to the following situation 1 or situation 2:

[0156] Case 1:

[0157] If the second communication device is the initiator requesting the establishment of the BA mechanism (for example, the originating STA), and the first wireless frame includes: the first field of the third identification information does not exist, or the third identification information is set to the first field of the first parameter value (for example, 0), then the second communication device performs at least one of the following operations: discarding the data unit (MAC Protocol Data Unit, MPDU) that has been transmitted and setting the sequence number to the last transmitted MPDU; immediately releasing or stopping the BA mechanism between the first communication device; and retransmitting after the duration indicated by the second identification information.

[0158] Immediately canceling or stopping the BA mechanism with the first communication device can avoid wasting communication resources and time, allowing normal communication to be restored as quickly as possible. Discarding already transmitted data units can prevent the transmission of erroneous data and ensure data consistency. At the same time, setting the sequence number to the last transmitted MPDU can help restore normal data transmission and avoid communication issues caused by sequence number confusion. Furthermore, waiting for a certain period of time before retransmitting can provide the communication device with additional time to attempt to resolve issues that may cause communication anomalies, thereby improving communication stability, reducing unnecessary retransmissions, and thus improving overall communication efficiency.

[0159] In some embodiments, if the second communication device acts as the initiator requesting the establishment of a BA mechanism, and the third identification information exists in each of the first fields included in the first wireless frame and the third identification information is not set to the first parameter value, then the second communication device performs at least one of the following operations before the earliest time point identified by the third identification information arrives: continue to send MPDU; discard the MPDU that has been transmitted and set the sequence number to the last transmitted MPDU; release or stop the Block ACK mechanism with the first communication device, and retransmit after the duration identified by the second identification information.

[0160] The second communication device continuously transmits MPDUs to ensure data transmission continuity, thereby maintaining the stability and reliability of the communication link. If the second communication device detects a communication anomaly or problem, discarding the transmitted MPDU and setting the sequence number to the last transmitted MPDU can prevent the transmission of erroneous data. This helps avoid the impact of erroneous data and ensures that the receiving end can correctly process the received data. In addition, disabling or stopping the Block ACK mechanism with the first communication device effectively terminates the current communication mechanism and retransmits after a certain period of time, helping to avoid wasting communication resources and time and quickly recover from communication anomalies.

[0161] Case 2:

[0162] If the second communication device serves as the recipient (for example, the recipient STA) requesting the establishment of the BA mechanism, and the first wireless frame includes: the first field of the third identification information does not exist, or the third identification information is set to the first field of the first parameter value (for example, 0), then the second communication device performs at least one of the following operations: sending a Block Ack frame to the first communication device, where the Block Ack frame identifies the reception status of the current MPDU; after sending the Block ACK frame, immediately canceling or stopping the Block Ack mechanism between the second communication device and the first communication device.

[0163] The second communication device sends a Block Ack frame to the first communication device, which identifies the current MPDU reception status. This informs the first communication device which data frames have been successfully received and which may need to be retransmitted. This helps the first communication device understand the data transmission status and take timely measures to maintain communication quality.

[0164] After the second communication device sends the Block Ack frame, immediately canceling or stopping the Block Ack mechanism with the first communication device can effectively terminate the current communication mechanism, help avoid wasting communication resources and time, and quickly recover in the event of communication anomalies.

[0165] If the second communication device serves as the recipient requesting the establishment of a BA mechanism, and the third identification information exists in each of the first fields included in the first wireless frame and the third identification information is not set to the first parameter value (for example, not 0), then the second communication device performs at least one of the following operations before the earliest time point identified by the third identification information arrives: continue to receive the MPDU sent by the first communication device; send a Block Ack frame to the first communication device before the earliest time point identified by the third identification information, and the Block Ack frame identifies the current MPDU reception status; and cancel or stop the Block ACK mechanism with the first communication device before the earliest time point identified by the third identification information.

[0166] The second communication device, as the recipient requesting the BA mechanism, can continue to receive data frames sent by the first communication device until the earliest time point identified by the third identification information arrives. This helps maintain the continuity of data transmission and ensures that the recipient can receive all transmitted data.

[0167] Among them, if a Block Ack frame is sent to the first communication device before the earliest time point identified by the third identification information, which identifies the reception status of the current MPDU, it can help the first communication device understand the reception status of the data frame and take timely measures to maintain communication quality.

[0168] Among them, canceling or stopping the Block Ack mechanism between the first communication device and the first communication device can effectively terminate the current communication mechanism, which helps to avoid wasting communication resources and time and quickly recover in the event of communication anomalies.

[0169] In some embodiments, a first communication device and a second communication device negotiate to establish a BA mechanism, and if the second communication device is coexisting within the device while sending or receiving data, the second communication device determines a second radio frame, where the second radio frame includes fourth identification information. The fourth identification information is used to inform the first communication device that the second communication device is engaged in communication services on other wireless communication media and to cancel or stop the Block ACK mechanism established with the first communication device. Furthermore, the second communication device sends the second radio frame, causing the first communication device to receive the second radio frame and, based on the fourth identification information carried in the second radio frame, cancel or stop the Block ACK mechanism established with the first communication device.

[0243] In some embodiments, the above-mentioned receiving module 701 is used to receive a first wireless frame sent by a first communication device; wherein, the first wireless frame includes first identification information, and the first identification information indicates that: the first communication device has a communication service of other wireless communication media, and releases or stops the Block ACK mechanism established between the first communication device and the second communication device.

[0244] Optionally, the receiving module 701 is configured to execute at least one of the communication steps (eg, step 203, step 501, but not limited thereto) executed by the second communication device 102 in any of the above methods, which will not be described in detail here.

[0245] As an optional implementation of the embodiment of the present disclosure, the aforementioned communication method further includes:

[0246] In the process of establishing a block acknowledgment mechanism between the access point device and the site device and transmitting data blocks, interference caused by in-device coexistence activities in the access point device or the site device will cause data loss during data block transmission. A device with in-device coexistence activities (first communication device) sends a DELBA frame to another communication device (second communication device) to report the in-device coexistence activities of the first communication device to the second communication device. The second communication device selects whether to continue transmitting and receiving data blocks based on the in-device coexistence activities of the first communication device, and determines the time to release / stop the Block Ack transmission mechanism or the time to retransmit data. Based on the above method, the loss of data packets and waste of communication resources caused by interference between communication devices due to in-device coexistence activities can be effectively avoided, further improving the reliability and efficiency of transmission.

[0247] Optionally, under a first condition, the first communication device sends a first radio frame to the second communication device to inform the second communication device of the interference problem caused by the in-device coexistence activity, to cancel / stop the Block Ack mechanism established between the two, and to inform the second communication device of relevant information about the in-device coexistence activity. The first condition includes but is not limited to: the first communication device and the second communication device have negotiated to establish a Block Ack mechanism, and the first communication device has in-device coexistence activity during the process of sending or receiving data. The first radio frame includes but is not limited to:

[0248] First identification information, indicating the presence of coexistence activity interference within the device, and instructing to release / stop the established Block Ack mechanism;

[0249] Second identification information, identifying the duration of the coexistence activity within the device;

[0250] The third identification information identifies the start time of the coexistence activity in the device; if the third identification information exists and its value is not 0, it identifies the start time point of the coexistence activity in the device; if the value of the third identification information is set to 0 or does not exist, it indicates that the coexistence activity in the device has occurred or is about to occur.

[0251] Optionally, the first radio frame may be a Delete BA (DELBA) frame. The first identification information may be a Reason Code field. For example, the Reason Code field is set to a first value (such as 72), indicating that the network device sending the first radio frame has an intra-device coexistence activity, and instructing the network device receiving the first radio frame to release / stop the Block Ack mechanism between the two. The first radio frame includes one or more first fields, each of which includes second identification information and optional third identification information. Optionally, the first radio frame may include a first element, and one or more first fields are included in the first element. The action field format of the first radio frame is shown in Table 1 above.

[0252] For example, the format of the first element is shown in FIG3 , wherein the first element includes one or more first fields, the first field includes a second subfield, and the second subfield includes a first information field and a second information field.

[0253] The first information field carries second identification information, identifying the duration of the coexistence activity within the device; and the second information field carries third identification information, identifying the start time of the coexistence activity within the device.

[0254] The first field further includes a first subfield, which includes but is not limited to a first identifier. The first identifier identifies whether the first field is the last first field included in the first element, that is, it implicitly identifies the number of first fields included in the first element. For example, if the first identifier is set to 1, it indicates that the first field is the last first subfield included in the first element; if the first identifier is set to 0, it indicates that the first field also contains other first subfields, and the first identifier in the subsequent first field is 0.

[0255] In some embodiments, after receiving the first radio frame, the second communications device performs the following response operations:

[0256] If the second communication device is the Originating STA that initiates the Block Ack mechanism: the first field contained in the first wireless frame contains a first field that does not contain the third identification information, or contains a first field with the third identification information set to 0, the second communication device performs the following operations: discards the MPDU that has been transmitted and sets the sequence number to the last transmitted MPDU; immediately releases / stops the Block Ack mechanism between the first communication device and the first communication device; and retransmits after the duration indicated by the second identification information.

[0257] If the third identification information exists in each first field contained in the first wireless frame and its value is not 0, the second communication device performs the following operations before the earliest time point identified by the third identification information arrives: continue to send MPDU; discard the MPDU that has been transmitted and set the sequence number to the last transmitted MPDU; release / stop the Block Ack mechanism with the first communication device; and retransmit after the duration identified by the second identification information.

[0258] If the second communication device is a Recipient STA of the Block Ack mechanism: if the first field included in the first wireless frame contains a first field that does not contain the third identification information, or contains a first field with the third identification information set to 0, the second communication device performs the following operations: sends a Block Ack frame to the first communication device, reports the current MPDU reception status to the first communication device; and immediately releases / stops the Block Ack mechanism between the second communication device and the first communication device after sending the Block Ack frame.

[0259] If the third identification information exists in each first field of the first field included in the first wireless frame and its value is not 0, the second communication device performs the following operations before the earliest time point identified by the third identification information: continues to receive the MPDU sent by the first communication device; sends a Block Ack frame to the first communication device before the earliest time point identified by the third identification information to report the current MPDU reception status to the first communication device; and cancels / stops the Block Ack mechanism with the first communication device before the earliest time point identified by the third identification information. The disclosed embodiment can effectively avoid coexistence interference within the device and improve data transmission efficiency and reliability.
