[0035] Exemplary embodiments will be described in detail herein, and examples thereof are shown in the accompanying drawings. When the following description refers to the accompanying drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present disclosure.

[0036] The present disclosure provides a device communication method, which is applied to a wireless communication scenario, for example, a scenario where a terminal performs wireless communication.

[0037] With the development of the wireless communication technology field, more and more families or companies use wireless communication technologies including Wi-Fi technology for wireless data transmission to achieve leisure or office work. Due to the progress of technology, users' requirements for terminal performance are constantly increasing. For example, users need clearer picture quality and sound quality, lower latency, etc. Therefore, the transmission rate of wireless data transmission needs to be increased. However, the current wireless protocol standard, that is, Wi-Fi 6, cannot meet the above high requirements for data transmission rate. Therefore, Wi-Fi 6 is revised to obtain the updated wireless protocol standard Wi-Fi 7.

[0038] Wi-Fi 7 introduces many new technologies on the basis of the Wi-Fi 6 standard. For example, it supports a larger channel bandwidth: 320MHz channel bandwidth, supports a higher-order Quadrature Amplitude Modulation (QAM): 4096-QAM, supports Multi-Link Operation (MLO), supports enhanced multi-user communication: (Multi-User Multiple-Input Multiple-Output, MU-MIMO), and supports multi-Access Point (AP) cooperation and other technologies. Among them, under the traditional wireless protocol standard, a terminal device can only select one frequency band supported by the traditional wireless protocol standard for data transmission. For example, under the Wi-Fi 6 protocol, it supports three frequency bands of 2.4GHz, 5GHz, and 6GHz for data transmission, but when performing data transmission, it can only select one of the three frequency bands of 2.4GHz, 5GHz, and 6GHz to transmit data.

[0039] Figure 1 It is a schematic diagram of a link connection for multi-link operation shown according to an exemplary embodiment. Under the Wi-Fi 7 protocol, it supports data transmission using three frequency bands of 2.4GHz, 5GHz, and 6GHz. As Figure 1As shown, based on multi-link operation in the Wi-Fi 7 protocol, multiple links can be simultaneously connected between an AP and a station (STA) for data transmission, improving the wireless data transmission speed. However, limited by the implementation of the manufacturer's protocol, in some scenarios, there will be a significant problem of performance degradation in multi-link operation. For example, in a weak signal scenario, the transmission rate of one of the multi-link operations is weak, resulting in a decrease in the overall data transmission rate and thus affecting network performance.

[0040] Therefore, the present disclosure provides a communication method. By monitoring the signal strength in each link of the multi-link and determining the target link for communication based on the signal strength of the link, it is ensured that the signal strength in the target link meets the communication requirements, thereby ensuring the network performance during the communication process.

[0041] The communication method provided by the embodiments of the present disclosure can be executed by a station. Among them, the station can be a device accessing the AP. For example, the station can be a terminal accessing the AP based on multi-link operation.

[0042] Figure 2 is a flowchart of a communication method shown according to an exemplary embodiment, as Figure 2 shown, including the following steps.

[0043] In step S11, the station monitors the signal reception strength of each link in the multi-link.

[0044] Among them, the multi-link is multiple links connected between the station and the access point.

[0045] In the embodiments of the present disclosure, based on the wireless standard protocol Wi-Fi 7, there can be multiple links between the AP and the station. When communicating, multiple links connected between the access point and the station can communicate simultaneously to provide higher bandwidth and better stability.

[0046] In step S12, based on the signal reception strength, communication is performed using the target link in the multi-link.

[0047] Among them, the target link is a link whose signal reception strength is greater than the signal reception strength threshold.

[0048] In the embodiments of the present disclosure, based on the signal reception strength of each link in the multi-link, a link whose signal reception strength is greater than the signal reception strength threshold in the multi-link is determined as the target link.

[0049] In the embodiments of the present disclosure, the target link can be multiple links whose signal reception strength is greater than the signal reception strength threshold.

[0050] In the embodiments of the present disclosure, the signal reception strength threshold can be obtained by analyzing different test data.

[0051] In the embodiments of the present disclosure, by monitoring the signal reception strength of each link in a multi-link, and using the link with a signal reception strength greater than the signal reception strength threshold in the multi-link as the target link for communication, the signal reception strength during communication is greater than the signal reception strength threshold, ensuring the performance of each link during communication, and further ensuring the network performance during communication, thus achieving fast and delay-free communication.

[0052] In the embodiments of the present disclosure, when it is monitored that the signal reception strength in the multi-link is greater than the signal reception strength threshold, the link state can be adjusted so that the link with a signal reception strength greater than the signal reception strength threshold can communicate.

[0053] Figure 3 is a flowchart of a communication method shown according to an exemplary embodiment, as Figure 3 shown, and includes the following steps.

[0054] In step S21, the station monitors the signal reception strength of each link in the multi-link.

[0055] In step S22, based on the signal reception strength, the multi-link state is adjusted and the target link is determined.

[0056] In step S23, communication is performed based on the determined target link.

[0057] Among them, step S21 is the same as step S11, and will not be elaborated here.

[0058] In the embodiments of the present disclosure, according to the signal reception strength of each link monitored by the station, the links with different signal reception strengths can be adjusted to different states.

[0059] In the embodiments of the present disclosure, the adjustment of the state of each link in the multi-link can be achieved through the station.

[0060] In the embodiments of the present disclosure, the station can select the link with a link signal reception strength greater than the signal reception strength threshold after adjusting the link state as the target link for communication.

[0061] In the embodiments of the present disclosure, the link state is adjusted based on the signal reception strength of the link, so as to ensure that the link with a signal reception strength greater than the reception strength threshold can be used as the target link for communication, and further make the signal reception strength of the link during communication greater than the signal reception strength threshold, ensuring the performance of each link during communication, and further ensuring the overall performance of the network during communication.

[0062] In the embodiments of the present disclosure, the signal reception strength threshold may include the signal reception strength of the first threshold and / or the signal reception strength of the second threshold. Among them, the first threshold is greater than the second threshold.

[0063] In the embodiments of the present disclosure, the station makes different adjustments to the link state according to the magnitude relationship between the signal strength detected on each link and the signal reception strength of the first threshold and / or the signal reception strength threshold of the second threshold.

[0064] In the embodiments of the present disclosure, the state adjustment of the link by the station may be to activate the link.

[0065] In the embodiments of the present disclosure, the state adjustment of the link by the station may be to deactivate the link.

[0066] In the embodiments of the present disclosure, the state adjustment of the link by the station may be to keep the link state unchanged.

[0067] Among them, the link state may be an active state or an inactive state.

[0068] Figure 4 It is a flowchart of a communication method shown according to an exemplary embodiment, as Figure 4 shown, including the following steps.

[0069] In step S31, based on the signal reception strength, adjust the multi-link state and determine the target link.

[0070] In step S321, it is monitored that there is a first link with a signal reception strength greater than the first threshold, and the link state of the first link is an inactive state.

[0071] In step S331, activate the first link and determine the target link as the activated first link.

[0072] In the embodiments of the present disclosure, when the station monitors that the signal reception strength of the first link in the multi-links is greater than the signal reception strength of the first threshold, the first link is adjusted to an active state and the target link is determined.

[0073] In one example, if after monitoring that the signal reception strength of the first link is greater than the first threshold, the first link is in an active state, then keep the active state of the first link unchanged, and determine the first link with a signal reception strength greater than the first threshold and in an active state as the target link.

[0074] In one example, if after monitoring that the signal reception strength of the first link is greater than the first threshold, the first link is in an inactive state, then the station activates the first link, and determines the first link with a signal reception strength greater than the first threshold and a link state adjusted to an active state as the target link.

[0075] In step S322, it is monitored that there is a second link with a signal reception strength less than the second threshold.

[0076] In step S332, deactivate the second link and determine that the target link is another link different from the second link.

[0077] In an embodiment of the present disclosure, when it is monitored that the signal reception strength of the second link is less than the signal reception strength of the second threshold, the second link is deactivated and the target link is determined.

[0078] In one example, after it is monitored that the signal reception strength of the second link is less than the second threshold, if the second link is in an active state, the station deactivates the second link and determines, as the target link, another link different from the second link, that is, a link that is greater than the second threshold and in an active state.

[0079] In one example, after it is monitored that the signal reception strength of the second link is less than the second threshold, if the second link is in a non - active state, the non - active state of the second link remains unchanged, and a link different from the second link is determined as the target link.

[0080] In step S323, it is monitored that there is a third link whose signal reception strength is greater than or equal to the second threshold and less than or equal to the first threshold.

[0081] In step S333, keep the link state of the third link unchanged and determine that the target link is the link in the active state among the third links.

[0082] Wherein, the link state includes an active state or a non - active state.

[0083] In an embodiment of the present disclosure, when it is monitored that the signal reception strength of the third link is greater than or equal to the second threshold and less than or equal to the first threshold, keep the link state unchanged and determine the target link.

[0084] In one example, when it is monitored that the signal reception strength of the third link is greater than or equal to the second threshold and less than or equal to the first threshold, and the third link is in an active state, keep the state of the third link unchanged and determine the active third link as the target link.

[0085] In one example, when it is monitored that the signal reception strength of the third link is greater than or equal to the second threshold and less than or equal to the first threshold, and the third link is in a non - active state, keep the non - active state of the third link unchanged and determine the active third link as the target link.

[0086] In an embodiment of the present disclosure, the links in the active state among the first link, the second link, and the third link can be simultaneously used as the target link for communication.

[0087] In an embodiment of the present disclosure, when the signal reception strength of a link in a multi-link is detected to be less than a second threshold, the link state is adjusted to make the link in an inactive state, where the link in the active state can be deactivated, or the link in the inactive state can be maintained to make the link with a signal reception strength less than the second threshold in the inactive state.

[0088] In an embodiment of the present disclosure, when the signal reception strength of a link in a multi-link is detected to be greater than a first threshold, the link state is adjusted to make the link in an active state, where the link in the inactive state can be activated, or the link in the active state can be maintained to make the link with a signal reception strength greater than the first threshold in the active state.

[0089] In an embodiment of the present disclosure, Figure 5 is a schematic diagram showing the relationship between the first threshold and the second threshold according to an exemplary embodiment, as Figure 5 shown, the first threshold is not equal to the second threshold, so there is a buffer interval between the first threshold and the second threshold. When the signal reception strength of a link in a multi-link is detected to be within this buffer interval, the current state of the link can be maintained to avoid frequent adjustment of the link state caused by fluctuations in the received signal strength, resulting in network instability.

[0090] In an embodiment of the present disclosure, the first threshold and the second threshold can be adjusted according to different measurement results of different hardware platforms.

[0091] In an embodiment of the present disclosure, by monitoring the signal reception strength of each link in a multi-link, the link with a signal reception strength less than the second threshold is in an inactive state; the link with a signal reception strength greater than the first threshold is in an active state; the state of the link with a signal reception strength between the first threshold and the second threshold is maintained unchanged, and all the links in the active state are used as target links for communication, so that the signal reception strength of all the links for communication is greater than the second state, thereby ensuring the performance of the links for communication.

[0092] In an embodiment of the present disclosure, before deactivating the link with a signal reception strength less than the second threshold, the packet loss state of the link with a signal reception strength less than the second threshold can also be detected, and the link with a signal reception strength less than the second threshold is deactivated based on the packet loss state of the link with a signal reception strength less than the second threshold.

[0093] Figure 6 is a flowchart of a communication method according to an exemplary embodiment, as Figure 6 shown, including the following steps.

[0094] In step S41, it is detected that there is a second link with a signal reception strength less than the second threshold.

[0095] In step S42, detect the packet loss status of the second link and determine that the packet loss status meets the status condition for deactivating the second link.

[0096] In an embodiment of the present disclosure, when a station detects that there is a second link in the multi-link with a signal reception strength less than a second threshold, it triggers the detection of the packet loss status of the link with a signal reception strength less than the second threshold.

[0097] In one example, when a station detects that there is a second link in the multi-link with a signal reception strength less than a second threshold, it detects the number of packet losses in the second link. If the number of packet losses in the second link is greater than a threshold, deactivate the second link; if the number of packet losses in the second link is less than or equal to the threshold, do not deactivate the second link.

[0098] In an embodiment of the present disclosure, the packet loss situation of the packets in the link can be judged by the response of the access point to the packets.

[0099] In an embodiment of the present disclosure, the station determines whether to deactivate the second link according to the packet loss status of the packets in the second link with a signal reception strength less than the second threshold, so that the link with a signal reception strength less than the second threshold but without packet loss can communicate, thereby ensuring that multiple links can be used simultaneously for communication during communication and improving the network performance of the communication.

[0100] In an embodiment of the present disclosure, periodic detection can be performed on each link in the multi-link.

[0101] Figure 7 is a flowchart of a communication method shown according to an exemplary embodiment, as Figure 7 shown, including the following steps.

[0102] In step S51, monitor the signal strength and link status of each link in the multi-link one by one.

[0103] In an embodiment of the present disclosure, the station can sequentially monitor each link in the multi-link. Among them, the station can monitor the signal reception strength of each link and the current link status, where the link status can be an active state or a non-active state.

[0104] In step S52, if it is detected that the signal reception strength and link status of the link meet the monitoring conditions, then monitor the next link.

[0105] Among them, the monitoring conditions include at least one of the following: the link signal reception strength is less than the second threshold and the link status is non-active; the link signal reception strength is greater than the first threshold and the link status is active; the link signal reception strength is greater than or equal to the second threshold and less than or equal to the first threshold, and the link status is active or deactivated.

[0106] In the embodiments of the present disclosure, when it is detected that the signal reception strength and the link state meet the monitoring conditions, the monitoring of the next link is continued.

[0107] In one example, when the station detects that the signal reception strength of the current link is less than the second threshold and the current link state is in an inactive state, the station monitors the next link; otherwise, the current link state is adjusted, where adjusting the link state may be deactivating the link with the signal reception strength less than the second threshold currently.

[0108] In one example, when the station detects that the signal reception strength of the current link is greater than the first threshold and the current link state is in an active state, the station monitors the next link; otherwise, the current link state is adjusted, where adjusting the link state may be activating the link with the signal reception strength greater than the first threshold before.

[0109] In one example, when the station detects that the signal reception strength of the current link is less than or equal to the first threshold and greater than or equal to the second threshold, and the current link state is in any state, the station may monitor the next link.

[0110] In the embodiments of the present disclosure, by monitoring each link in multiple links one by one for the signal reception strength and the link state, and when it is determined that the signal reception strength and the link state of the currently monitored link meet the monitoring conditions, the next link is detected, so that the station can determine whether each link in the multiple links meets the communication requirements, and further ensure that the link for communication works in the best performance state.

[0111] In the embodiments of the present disclosure, the communication method is described in combination with the following examples.

[0112] In the embodiments of the present disclosure, the communication method can be applied to MLO based on Wi-Fi 7 to achieve communication between a station and an access point.

[0113] In the embodiments of the present disclosure, as Figure 1 shown, the STA can associate with the AP in the manner of MLO, where there may be three links for communication between the STA and the AP, namely link 1, link 2, and link 3.

[0114] In the embodiments of the present disclosure, Figure 8 is a flowchart of a communication method shown according to an exemplary embodiment. As Figure 8As shown, when the station detects whether the received signal strength indication (RSSI) in link1 is greater than the first threshold, if the RSSI in link1 is greater than the first threshold and the current state of link1 is the active state (i.e., link1 is enabled), then the next link is detected, that is, link2 is detected; if the RSSI in link1 is greater than the first threshold and the current state of link1 is the non-active state (i.e., link1 is disabled), then the station activates link1, that is, enables link1.

[0115] If the RSSI in link1 is less than the first threshold, the station monitors whether the RSSI in link1 is greater than the second threshold. If the RSSI in link1 is greater than the second threshold, then the next link is continuously monitored; if the RSSI in link1 is less than the first threshold and less than the second threshold, then link1 is deactivated, that is, link1 is disabled.

[0116] In the embodiments of the present disclosure, the station can periodically repeat the detection of the received signal strength of each link in the MLO combination, so as to ensure that the received signal strength of each link in the MLO combination is greater than the second threshold, thereby ensuring the overall performance of MLO.

[0117] Based on the same concept, the embodiments of the present disclosure also provide a communication device.

[0118] It can be understood that, in order to implement the above functions, the communication device provided by the embodiments of the present disclosure includes the corresponding hardware structure and / or software module for executing each function. Combining the units and algorithm steps of the examples disclosed in the embodiments of the present disclosure, the embodiments of the present disclosure can be implemented in the form of hardware or a combination of hardware and computer software. Whether a certain function is executed in the way of hardware or computer software driving hardware depends on the specific application and design constraints of the technical solution. Those skilled in the art can use different methods for each specific application to implement the described functions, but such implementation should not be considered to exceed the scope of the technical solution of the embodiments of the present disclosure.

If it is detected that there is a second link with a signal reception strength less than the second threshold, deactivate the second link and determine the target link as other links different from the second link. If it is detected that there is a third link with a signal reception strength greater than or equal to the second threshold and less than or equal to the first threshold, keep the link state of the third link unchanged, where the link state includes the active state or the inactive state, and determine the target link as the link in the third link with the active state. Here, the first threshold is greater than the second threshold.

[0124] In one embodiment, before deactivating the second link, the communication unit 102 is further configured to: Detect the packet loss status of the second link and determine that the packet loss status meets the status condition for deactivating the second link.

[0125] In one embodiment, the monitoring unit 101 monitors the signal reception strength of each link in multiple links in the following manner: Monitor the signal reception strength and the link state of each link in the multiple links one by one. If it is detected that the signal reception strength and the link state of the link meet the monitoring conditions, monitor the next link. The monitoring conditions include at least one of the following: The link signal reception strength is less than the second threshold and the link state is the inactive state.
