[0042] The first device sends Bluetooth data to the second device using an idle channel in the second frequency band.

[0043] In the above embodiment, the first device can use the channel of the second frequency band to communicate with the second device via Bluetooth, and the frequency band of Bluetooth communication can be expanded to a higher frequency band. When there is an idle channel in the higher frequency band, the Bluetooth device can use the channel of the higher frequency band to transmit Bluetooth data, which can effectively improve the quality of Bluetooth communication.

[0044] In conjunction with some embodiments of the first aspect, in some embodiments, the first device includes a Wireless Fidelity (Wi-Fi) module,

[0045] The detecting the channels in the second frequency band to determine idle channels in the second frequency band includes:

[0046] The Wi-Fi module is used to detect channels in the second frequency band to determine idle channels in the second frequency band.

[0047] In the above embodiment, the Wi-Fi module can be used to detect channels in the second frequency band, allowing for reuse of devices in the first device. This improves the quality of Bluetooth communication while ensuring cost effectiveness. Furthermore, with the assistance of the Wi-Fi module, the first device can maintain the continuity of Bluetooth data transmission without interrupting Bluetooth communication in the first frequency band.

[0048] In conjunction with some embodiments of the first aspect, in some embodiments, the first device detects channels in the second frequency band to determine idle channels in the second frequency band, including:

[0049] The first device detects the channels of the second frequency band based on a Detect And Avoid (DAA) mechanism to determine an idle channel of the second frequency band.

[0050] In the above embodiment, the DAA mechanism can be used to detect the channel of the second frequency band. Compared with the listen before talk (LBT) mechanism, it can effectively improve the efficiency of the first device in detecting the channel of the second frequency band with a wider bandwidth, and can effectively improve the efficiency and reliability of Bluetooth communication.

[0051] In combination with some embodiments of the first aspect, in some embodiments, the first device detects the channel of the second frequency band based on the detection and avoidance DAA mechanism to determine an idle channel of the second frequency band, including:

[0052] After sending first information to the second device using a first channel, the first device determines whether the first channel is an idle channel, or receives second information sent by the second device, where the second information is used to indicate whether the first channel is an idle channel;

[0053] The first device determines that the first channel is an idle channel, and adds the first channel to a first candidate channel list;

[0061] The first device determines that the number of idle channels in the first candidate channel list is less than a quantity threshold, and uses the first frequency band to send Bluetooth data to the second device.

[0111] FIG1 is a schematic diagram of the architecture of a communication system according to an embodiment of the present disclosure (a system diagram including only the subjects related to the invention point and their important counterparts, and the number of subjects corresponds to the number of subjects involved in the invention point).

[0112] As shown in Figure 1, a communication system 100 includes a first device 101 and a second device 102. In some embodiments, the first device 101 and the second device 102 can both be devices capable of Bluetooth communication. In some embodiments, the first device 101 can be provided as a central device in Bluetooth communication, and the second device 102 can be provided as a peripheral device in Bluetooth communication.

[0113] It's worth noting that two devices interconnected via Bluetooth technology can be divided into two roles: central and peripheral. The central device determines the specific frequency bands and channels, as well as the modulation and demodulation parameters, used by both parties. Typically, the central device supports multi-mode communication, meaning it can switch between Wi-Fi and Bluetooth modes using time-division multiplexing. For example, a smartphone can have both a Bluetooth module and a Wi-Fi module, switching between them using time-division multiplexing.

[0114] In some embodiments, the first device 101 and the second device 102 can be any one of a terminal, an access network device, and a core network device. For example, the first device 101 can be a smartphone, and the first device 101 can be connected to a device such as a headset, a bracelet, a watch, glasses, a tablet computer, a laptop computer, a temperature and humidity sensor, a medical sensor, a light bulb, a socket, a switch, etc. via Bluetooth. The second device 102 can be any one of these devices. After the first device 101 and the second device 102 establish a connection, the two parties can realize the transmission of audio data or other types of data, query and read the status value of the sensor, adjust the device mode or other setting parameters, etc.

[0115] 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.

[0116] 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.

[0117] The embodiments of the present disclosure may be applied to Bluetooth (registered trademark)), Star Flash system, Long Term Evolution (LTE), LTE-Advanced (LTE-A), LTE-Beyond (LTE-B), SUPER 3G, IMT-Advanced, 4th generation mobile communication system (4G), 5th generation mobile communication system (5G), 5G new radio (NR), future radio access (FRA), new radio access technology (RAT), new radio (NR), new radio access (NX), future generation radio access (FX), Global System for Mobile communications (GSM (registered trademark)), CDMA2000, Ultra Mobile Broadband (UMB), IEEE 802.11 (Wi-Fi (registered trademark)), IEEE 802.16 (WiMAX (registered trademark)), IEEE 802.20, Ultra-WideBand (UWB), Public Land Mobile Network (PLMN) networks, Device-to-Device (D2D) systems, Machine-to-Machine (M2M) systems, Internet of Things (IoT) systems, Vehicle-to-Everything (V2X), systems utilizing other communication methods, and next-generation systems based on and extending these methods. Furthermore, multiple systems may be combined (for example, a combination of Bluetooth, Starlink, LTE, LTE-A, and 5G).

[0118] In some embodiments, in Bluetooth communication, in order to avoid spectrum interference in the 2.4 GHz band, the communication band may be extended to higher frequency bands, such as the 5.1 GHz and / or 5.8 GHz bands.

[0119] In some embodiments, the listen before talk (LBT) channel access mechanism refers to a mechanism in which a clear channel assessment (CCA) operation is performed before a Bluetooth device transmits data to determine whether the current channel is occupied by other devices. If the current channel is occupied, the Bluetooth device selects another unoccupied channel for data transmission. To avoid interference during the transmission process, the Bluetooth device will continue to monitor the channel during the data transmission process. If interference is detected, the Bluetooth device will immediately terminate the data transmission and perform channel detection. If another unoccupied channel is detected, it will switch to that channel to ensure the reliability of data transmission.

[0120] However, when the LBT mechanism faces interference from other communication technologies in higher frequency bands, it will stop data transmission after detecting channel occupancy until an idle channel is detected. Since the channel bandwidth of Bluetooth communication technology is only 2MHz, the efficiency of idle channel detection in higher frequency bands is low, which will seriously affect the rate, latency and reliability of Bluetooth communication in higher frequency bands.

[0121] FIG2 is an interactive diagram of a Bluetooth communication method according to an embodiment of the present disclosure. As shown in FIG2 , the embodiment of the present disclosure relates to a Bluetooth communication method, which includes:

[0122] Step S2101: The first device detects channels in a first frequency band based on an LBT mechanism to determine idle channels in the first frequency band.

[0123] In some embodiments, the first frequency band may include a 2.4 GHz frequency band. The 2.4 GHz frequency band may refer to a frequency band of 2400-2483.5 MHz with a total bandwidth of 83.5 MHz. Optionally, the first frequency band may also include other frequency bands, which are not limited in the embodiments of the present disclosure.

[0124] In some embodiments, the first device detecting the channels of the first frequency band based on the LBT mechanism may mean that before the first device uses the first frequency band to send Bluetooth data, it detects the channels of the first frequency band to determine idle channels in the first frequency band. Alternatively, the first device detecting the channels of the first frequency band may mean that the first device determines whether interference of each channel of the first frequency band exceeds a threshold.

[0125] For example, before the first device uses the channel of the first frequency band to send data, it can perform an idle channel assessment on each channel. If it is determined that there is a signal higher than the detection threshold on the frequency of a certain channel, it can be determined that the channel is not an idle channel. Otherwise, it can be determined that the channel is an idle channel.

[0126] In some embodiments, step S2101 can be performed multiple times to determine all idle channels in the first frequency band. Optionally, after detecting channels in the first frequency band, the first device can add the idle channels in the first frequency band to a second candidate channel list, so that the terminal can perform step S2102 based on the second candidate channel list. For optional implementations of the second candidate channel list, please refer to the descriptions related to steps S2102 and S2106 and are not further described here.

[0127] Step S2102: The first device sends Bluetooth data to the second device using the first frequency band.

[0128] In some embodiments, the first device uses an idle channel in the first frequency band to send Bluetooth data to the second device. Optionally, the first device includes a Bluetooth module, and the first device uses the Bluetooth module to send Bluetooth data to the second device using an idle channel in the first frequency band.

[0129] In some embodiments, the first device updates a second candidate channel list based on a detection result of channels in the first frequency band. The second candidate channel list may include at least two idle channels in the first frequency band. For example, the first device may map the idle channels in the first frequency band to the second candidate channel list, where the channels in the second candidate channel list are arranged in descending order according to their corresponding channel indexes.

[0130] Optionally, the first device can send Bluetooth data according to the second candidate channel list. For example, the first device can send Bluetooth data by frequency hopping according to the second candidate channel list, wherein the first device can select an idle channel according to the second candidate channel list to send a part of the Bluetooth data, and when the residence time of the channel ends, jump to other idle channels in the second candidate channel list to send another part of the Bluetooth data, until the Bluetooth data is sent, or the Bluetooth connection is disconnected, or it switches to using the second frequency band to send Bluetooth data.

[0131] In some embodiments, the first device may include a Bluetooth module, and the first device may utilize the Bluetooth module to send Bluetooth data to the second device using the first frequency band. Optionally, the Bluetooth module may use the first frequency band and the second frequency band to transmit and receive signals.

[0132] In some embodiments, the bandwidth of the second frequency band is greater than the bandwidth of the first frequency band, and the second frequency band is higher than the first frequency band.

[0133] In some embodiments, the second frequency band includes at least one of a 5.1 GHz frequency band and a 5.8 GHz frequency band, wherein the 5.1 GHz frequency band may be a frequency band of 5150-5350 MHz with a total bandwidth of 200 MHz, and the 5.8 GHz frequency band may be a frequency band of 5725-5850 MHz with a total bandwidth of 125 MHz.

[0134] For example, the Bluetooth module can be a combo chip, including a 2.4GHz Bluetooth module and a 5.1GHz and / or 5.8GHz Bluetooth module. The 2.4GHz Bluetooth module can use the first frequency band to transmit and receive signals, and the 5.1GHz and / or 5.8GHz Bluetooth module can use the second frequency band to transmit and receive signals.

[0135] When the first device performs Bluetooth communication with multiple devices, it can communicate with some devices using the first frequency band while communicating with other devices using the second frequency band.

[0136] In some possible implementation scenarios, when a first device performs Bluetooth communication with another device, it can only use one of the first frequency band or the second frequency band for Bluetooth data transmission. For example, when the first device uses the first frequency band to send Bluetooth data to the second device and / or detects idle channels in the first frequency band, it cannot use the second frequency band to send Bluetooth data to the second device. Alternatively, when the first device uses the second frequency band to send Bluetooth data to the second device and / or detects idle channels in the second frequency band, it cannot use the first frequency band to send Bluetooth data to the second device.

[0137] In some embodiments, the second device receives Bluetooth data sent by the first device using the first frequency band. Optionally, both the first device and the second device include a Bluetooth module, and the second device receives Bluetooth data sent by the first device using the Bluetooth module.

[0138] In some embodiments, before the first device sends Bluetooth data to the second device using the second frequency band, the first device keeps sending Bluetooth data to the Bluetooth device using the first frequency band.

[0139] Step S2103: The first device sends the first information to the second device using a channel in the second frequency band.

[0140] In some embodiments, a first device sends first information to a second device using a first channel, where the first channel can be any channel in the second frequency band. For example, the first channel can be the channel with the lowest center frequency in the second frequency band, or the channel with the highest center frequency, or can be a channel randomly selected by the first device, although this disclosure is not limited thereto.

[0141] In some embodiments, the first information is used by the first device to detect a channel in the second frequency band. Alternatively, the first information is used by the first device to detect the first channel.

[0142] In some embodiments, the first information is used to instruct the second device to detect a channel in the second frequency band. Alternatively, the first information is used to instruct the second device to detect a channel on which the first information is currently transmitted. Alternatively, the first information is used to instruct the second device to detect the first channel.

[0143] In some embodiments, the first device uses a Wi-Fi module to send the first information to the second device using the first channel. Alternatively, the first device may also use another module that can transmit and receive signals using a channel in the second frequency band, such as a 5.1 GHz or 5.8 GHz radio frequency unit, to send the first information to the second device using the first channel.

[0144] In some embodiments, the second device also has a Wi-Fi communication function. For example, the second device is also provided with a Wi-Fi module to receive the first information sent by the first device using the Wi-Fi module.

[0145] Optionally, before the first device uses the second frequency band to send the first information, it can first use the Bluetooth module to send the channel information of the second frequency band to the second device. For example, the Bluetooth data sent by the first device to the second device includes a Bluetooth data message corresponding to the channel information of the second frequency band. The channel information of the second frequency band may include, for example, a service set identifier (SSID) and a key corresponding to each channel of the second frequency band. In this way, the second device can more reliably receive the first information sent by the first device.

[0146] In some embodiments, the second device receives the first information sent by the first device using the first channel. Alternatively, the second device receives the first information sent by the first device using the first Wi-Fi module and the first channel using the second Wi-Fi module.

[0147] In some embodiments, the second device receives channel information sent by the first device using a Bluetooth module, and the second device receives the first information sent by the first device using a Wi-Fi module based on the channel information, wherein the channel information includes information such as the SSID and key corresponding to each channel in the second frequency band.

[0148] In some embodiments, step S2103 may be initiated simultaneously with step S2102 or before step S2102. Optionally, when the first device uses the first frequency band to send Bluetooth data to the second device, it begins detecting channels in the second frequency band. Specifically, the first device uses the first channel to send the first information to the second device. Alternatively, after completing channel detection in the first frequency band, the first device detects channels in the second frequency band, for example, using the first channel to send the first information to the second device.

[0149] In some embodiments, the first information may also be "channel detection data", "detection indication information", etc., and the embodiments of the present disclosure do not limit their names.

[0150] Step S2104: The second device sends second information to the first device.

[0151] In some embodiments, after receiving the first information sent using a channel in the second frequency band, the second device detects the channel to determine the second information. Optionally, the second information is used to indicate whether the channel on which the first device sent the first information is an idle channel.

[0152] In some embodiments, the second information is used to indicate whether the first channel is an idle channel. Optionally, the second information is used by the first device to determine whether the first channel is an idle channel.

[0153] In some embodiments, the second device may detect the first channel to determine whether the first channel is an idle channel. Alternatively, the second device may detect the signal strength of the first channel to determine whether the first channel is an idle channel. For example, if the second device determines that a signal above a detection threshold exists on the first channel, it may determine that interference exists on the first channel and that the first channel is not an idle channel. The second device may further transmit second information indicating that the second channel is not an idle channel.

[0154] In some embodiments, the second information may be sent by the second device using the channel used by the first device to send the first information, such as the first channel, or may be sent using other channels, which is not limited in the embodiments of the present disclosure.

[0155] In some embodiments, the first device receives the second information sent by the second device. Alternatively, the first device receives the second information sent by the second device and performs step S2106 according to the second information.

[0156] In some embodiments, the second information may be a “response message”, “feedback information”, etc., and the embodiments of the present disclosure do not limit the names thereof.

[0157] In some embodiments, step S2104 may be an optional step. For example, if the first device can independently determine whether the channel used by the first device to send the first information is an idle channel, the second device may not send the second information, or may send feedback information that does not include the second information. For example, after receiving the first information, the second device sends feedback information that does not include information indicating whether the channel used by the first device to send the first information is an idle channel. Optionally, if the first device can independently determine whether the channel used by the first device to send the first information is an idle channel, the first device may not expect to receive the second information.

[0158] Step S2105: The first device determines whether the channel used for sending the first information this time is an idle channel.

[0159] In some embodiments, the first device determines whether a channel used to send the first information is an idle channel based on the second information. Alternatively, the first device determines whether the first channel is an idle channel based on the second information.

[0160] In some embodiments, the first device itself determines whether the channel used to send the first information is an idle channel. Optionally, after sending the first information, the first device detects the first channel to determine whether the first channel is an idle channel. Optionally, the first device may detect the signal strength of the first channel to determine whether the first channel is an idle channel. For example, if the first device determines that a signal strength above a detection threshold exists on the first channel, it may determine that interference exists on the first channel and that the channel is not an idle channel.

[0161] In some embodiments, when the first device determines that the channel used to send the first information this time is not an idle channel, it can return to step S2103 and send the first information to the second device using a channel different from the channel used to send the first information previously.

[0162] Optionally, the first device uses a second channel to send the first information. The second channel is a channel in the second frequency band, and the second channel is a channel in the second frequency band that is different from the first channel. For example, the first channel may be a channel with a high center frequency in the second frequency band, and the second channel may be a channel with the second highest center frequency. The center frequencies of the channels used by the first device to send the first information multiple times may decrease successively.

[0163] In some embodiments, if the first device determines that the channel used to send the first information is an idle channel, it can be determined that there is an idle channel in the second frequency band, and step S2106 and subsequent steps can be executed.

[0164] Step S2106: The first device adds the channel used for sending the first information this time to the first candidate channel list.

[0165] In some embodiments, the first candidate channel list may be a candidate channel list corresponding to the second frequency band.

[0166] In some embodiments, the first candidate channel list may include one or more idle channels determined by the first device performing steps S2103 to S2105 multiple times. Alternatively, the first candidate channel list may be empty.

[0167] In some embodiments, the first device may maintain multiple candidate channel lists for the second device. For example, the first device may maintain a second candidate channel list corresponding to the first frequency band and a first candidate channel list corresponding to the second frequency band. The first device may select one of the candidate channel lists for Bluetooth data transmission. Optionally, the first device may preferentially use a channel in the first candidate channel list corresponding to the second frequency band to transmit Bluetooth data to the second device.

[0168] In some embodiments, adding the channel used for sending the first information to the first candidate channel list may refer to mapping the channel to the first candidate channel list, wherein the first candidate channel list may be arranged in descending order according to the indexes corresponding to the channels.

[0169] In some embodiments, after the first device adds the channel used to send the first information this time to the first candidate channel list, it can execute step S2106 while continuing to execute step S2103 and subsequent steps. The first device can send the first information to the second device using a channel different from the channel used to send the first information previously, until the first device uses all channels of the second frequency band to send the first information.

[0170] Optionally, the first device sends the first information using a second channel, where the second channel is a channel in a second frequency band and is different from the first channel in the second frequency band.

[0171] In some embodiments, the first candidate channel list may also be an “available channel list”, “idle channel list”, “high frequency band available channel list”, etc., and the embodiments of the present disclosure do not limit their names.

[0172] In some embodiments, in the above steps S2103 to S2106, the channel detection mechanism in which the first device first sends the first information to the second device and then detects the channel can be called a DAA mechanism.

[0173] That is, steps S2103 to S2105 may be a process in which the first device detects the channels of the second frequency band based on the DAA mechanism to determine idle channels in the second frequency band.

[0174] In some embodiments, the first device may use a Wi-Fi module to detect a channel in the second frequency band based on a DAA mechanism. Alternatively, the first device may use a Wi-Fi module to send the first information to the second device using a channel in the second frequency band, and then detect the channel.

[0175] In some embodiments, steps S2103 to S2105 may be performed multiple times to determine whether each channel in the second frequency band is an idle channel. Optionally, the channel used by the first device to send the first information each time in step S2103 is different until the first device uses all channels in the second frequency band to send the first information. Optionally, after the first device has traversed all channels in the second frequency band, steps S2103 to S2105 may be repeated to update the first candidate channel list. For example, after the first device determines that a certain channel is an idle channel and adds it to the first candidate channel list, if the first device re-executes the corresponding steps and determines that the channel is no longer an idle channel, the channel in the first candidate channel list may be deleted, and step S2107 and subsequent steps may be performed.

[0176] Step S2107: The first device determines whether the number of idle channels in the first candidate channel list is greater than or equal to a number threshold.

[0177] In some embodiments, the first candidate channel list is a candidate channel list corresponding to the second frequency band, and the idle channels therein are all idle channels of the second frequency band.

[0178] In other embodiments, the first candidate channel list may not only be a candidate channel list corresponding to the second frequency band, but may also be a candidate channel list corresponding to other frequency bands. In this case, the idle channels in the first candidate channel list may not be limited to idle channels in the second frequency band. Furthermore, step S2107 may be replaced by: the first device determines whether the number of idle channels in the second frequency band in the first candidate channel list is greater than or equal to a number threshold.

[0179] In some embodiments, the quantity threshold may be, for example, 1 or 2, which is not limited in the embodiments of the present disclosure.

[0180] In some embodiments, if the first device determines that the number of idle channels in the first candidate channel list is greater than or equal to a quantity threshold, step S2108 may be executed. Alternatively, if the first device determines that the number of idle channels in the second frequency band is greater than or equal to a quantity threshold, step S2108 may be executed. For example, if the quantity threshold is 2, and the first device determines that the number of idle channels in the second frequency band is greater than or equal to 2, then switching to the second frequency band may be performed.

[0181] In some embodiments, if the first device determines that the number of idle channels in the first candidate channel list is less than a threshold, the process may return to step S2102 or S2101. Alternatively, if the first device determines that the number of idle channels in the second frequency band is less than a threshold, the process may return to step S2102 or S2101. For example, if the threshold is 2 and the first device determines that the number of idle channels in the second frequency band is less than 2, the process may maintain Bluetooth communication in the first frequency band.

[0182] Optionally, if the first device determines that there are no idle channels in the second frequency band after executing steps S2103 to S2104 multiple times, the first device may return to step S2102 or step S2101. For example, if the quantity threshold is 1 and the first device determines that there are no idle channels in the second frequency band, it may maintain Bluetooth communication in the first frequency band.

[0183] Step S2108: The first device sends Bluetooth data to the second device using an idle channel in the second frequency band.

[0184] In some embodiments, a third channel is determined from the first candidate channel list, and the third channel is used to send Bluetooth data to the second device, where the third channel is an idle channel in the second frequency band.

[0185] In some embodiments, the third channel may be any channel in the candidate channel list. Alternatively, the third channel may be an unused channel in the candidate channel list. Alternatively, the third channel may be the channel with the highest center frequency among the unused channels in the candidate channel list. Alternatively, the third channel may be the channel with the highest index value among the unused channels in the candidate channel list, wherein the channels in the candidate channel list are arranged in descending order of index.

[0186] In some embodiments, step S2108 is performed after the first device stops using the first frequency band to send Bluetooth data.

[0187] For example, the first device can detect the channels of the second frequency band, determine that there are idle channels in the second frequency band, and update the first candidate channel list based on the idle channels of the second frequency band. Then, it can stop using the channels of the first frequency band to send Bluetooth data and switch to using the channels in the candidate channel list corresponding to the second frequency band to send Bluetooth data.

[0188] In some embodiments, the first device may utilize a Bluetooth module to transmit Bluetooth data using a third channel. That is, after the first device utilizes a Wi-Fi module to detect an idle channel in the second frequency band, the Bluetooth module may switch from operating in the first frequency band to operating in the second frequency band and transmit Bluetooth data using a channel in the second frequency band.

[0324] FIG6 is a flow chart of a Bluetooth communication method according to an embodiment of the present disclosure. As shown in FIG6 , the present disclosure embodiment relates to a communication method, which can be applied to a central device in a Bluetooth communication system, such as a first device, and includes:

[0325] Step S6101: determine to perform Bluetooth 2.4 GHz channel assessment.

[0326] In some embodiments, the first device determines to be powered on, or determines that the Bluetooth module is activated, determines to perform a channel assessment in the Bluetooth 2.4 GHz frequency band, and executes step S6102.

[0327] Step S6102: Based on the LBT mechanism, determine whether an idle channel is detected.

[0328] In some embodiments, if an idle channel in the 2.4 GHz frequency band is detected, step S6103 and subsequent steps may be performed. If no idle channel is detected, the process may return to step S6101 and perform further idle channel detection.

[0329] Step S6103: Update the 2.4 GHz available channel list.

[0330] Step S6104, determine to perform Bluetooth 2.4 GHz communication.

[0331] Step S6105: Wi-Fi 5.1 GHz and / or 5.8 GHz channel assessment.

[0332] In some embodiments, when Bluetooth is communicating at 2.4 GHz, it may notify WI-FI to perform 5.1 GHz and / or 5.8 GHz channel assessment.

[0333] Step S6106: Based on the DAA mechanism, determine whether an idle channel is detected.

[0334] In some embodiments, if an idle channel is found, steps S6107 and S6108 may be performed, and Wi-Fi may notify Bluetooth to switch to an available channel. If no idle channel is found, the process may return to step S6101, and Wi-Fi may notify Bluetooth to continue channel detection at 2.4 GHz.

[0335] Step S6107: Update the 5.1 GHz and / or 5.8 GHz available channel list.

[0336] Step S6108: Determine to perform Bluetooth 5.1 GHz and / or 5.8 GHz communication.

[0337] In some embodiments, after the device sends data via Bluetooth on a selected channel in a higher frequency band, it switches to Wi-Fi mode and detects the occupancy of the same channel. If it finds that there is communication interference from other Wi-Fi devices on the same channel, it immediately detects the occupancy of other channels in the higher frequency band and adjusts the channel used for subsequent Bluetooth communications accordingly (possibly switching to other idle channels in the same frequency band, or switching to a lower frequency band).

[0338] In the disclosed embodiment, the DAA algorithm can use Wi-Fi to help Bluetooth devices achieve more efficient channel evaluation and access in higher frequency bands (e.g., 5.8 GHz). As long as there are other available channels, Bluetooth data transmission will not be interrupted, thus maintaining the high rate of Bluetooth data transmission. If the Bluetooth LBT algorithm is continued to be used in higher frequency bands, first of all, the channel detection efficiency of Bluetooth is lower than that of Wi-Fi, and the Bluetooth data transmission will be temporarily interrupted due to interference from other communication technologies (e.g., Wi-Fi) in Bluetooth detection, affecting the communication rate, delay and reliability.

[0339] In the embodiments of the present disclosure, some or all of the steps and their optional implementations may be arbitrarily combined with some or all of the steps in other embodiments, or may be arbitrarily combined with the optional implementations of other embodiments.
