[0001] This application claims priority to the Chinese patent application filed with the State Intellectual Property Office on January 15, 2024, with application number 202410056854.5 and invention name “Signal detection method and device for wireless headphones”, the entire contents of which are incorporated by reference into this application. Technical Field

[0002] The present application relates to the field of wireless communications, and in particular to a signal detection method and device for wireless earphones. Background Art

[0003] After a wireless headset successfully establishes a wireless connection with a terminal (such as a mobile phone or computer), wireless communication can begin. During this process, the wireless channel between the headset and the terminal changes, and the relative positions of the headset and the terminal are not fixed. Therefore, wireless headsets with dual or multiple antennas continuously monitor the signal quality of each antenna to ensure communication quality between the headset and the terminal.

[0004] Currently, wireless headsets can communicate with a terminal using only one antenna at a time. To measure the signal quality of antennas other than the current one, the headset must switch the antenna used for communication with the terminal. Poor signal quality from the other antennas can affect the headset's ability to receive audio frames from the terminal, resulting in a poor user experience. Summary of the Invention

[0005] The present application provides a signal detection method and device for wireless headphones, which can measure the signal quality of multiple antennas of wireless headphones without affecting the user experience.

[0006] To achieve the above objectives, this application adopts the following technical solutions:

[0007] In a first aspect, a signal detection method for a wireless headset is provided. The method can be performed by the wireless headset. The wireless headset here can refer to the wireless headset itself or a processor, module, logical node, chip, or chip system in the wireless headset that implements the method.

[0008] The method includes: receiving a first signal frame through a first antenna; when the first signal frame is successfully received, switching from the first antenna to a second antenna and detecting the signal quality of the second antenna; receiving a second signal frame through a target antenna, the second signal frame being the next initially transmitted signal frame of the first signal frame, and the target antenna being the antenna with the best signal quality between the first antenna and the second antenna.

[0009] Based on the method provided in the first aspect above, since the wireless headset detects the signal quality of the second antenna before receiving the next initial transmission signal frame of the first signal frame after successfully receiving the first signal frame, the signal detection method neither affects the playback of the first signal frame nor affects the reception of the next initial transmission signal frame of the first signal frame, thereby maximizing the user experience.

[0010] In one possible implementation, the method further includes: sending a first response message, the first response message indicating that the first signal frame failed to be received; detecting the signal quality of the second antenna, including: receiving a third signal frame through the second antenna, the third signal frame being a retransmitted signal frame of the first signal frame; and determining the signal quality of the second antenna based on the third signal frame.

[0011] Based on the above possible implementation, the wireless headset can determine the signal quality of the second antenna according to the retransmitted signal frame of the first signal frame, thereby not affecting the reception of the next initially transmitted signal frame of the first signal frame.

[0012] In a possible implementation, the method further includes: in a case where the third signal frame fails to be received, sending second response information, where the second response information indicates that the third signal frame is received successfully.

[0013] Based on the above possible implementation, since the third signal frame is a retransmitted signal frame of the first signal frame and is used to determine the signal quality of the second antenna, and the first signal frame has been successfully received, even if the third signal frame fails to be received, a second response message can be sent to indicate that the third signal frame has been successfully received. In this way, the transmitter of the first signal frame (e.g., the terminal) does not need to retransmit the first signal frame. In this way, even if the third signal frame fails to be received, it will not affect the reception of the next initially transmitted signal frame of the first signal frame.

[0014] In a possible implementation, detecting the signal quality of the second antenna includes: sending a first detection frame through the second antenna; receiving a first response frame through the second antenna, the first response frame being used to indicate receipt of the first detection frame; and determining the signal quality of the second antenna based on the first response frame.

[0015] Based on the above possible implementation, the wireless headset transmits a first detection frame, causing the receiving end (e.g., a terminal) of the first detection frame to transmit a first response frame to the wireless headset. The wireless headset can then determine the signal quality of the second antenna based on the first response frame without affecting the reception of the next initial transmission signal frame following the first signal frame.

[0016] In a possible implementation, the method further includes: playing audio data carried by the first signal frame.

[0017] Based on the above possible implementation methods, after the wireless headset successfully receives the first signal frame, it can play the audio data carried by the first signal frame. In this way, while playing the audio data carried by the first signal frame, the signal quality of the second antenna is detected, thereby maximizing the user experience.

The processing module may, for example, be a processor.

[0020] In combination with the above second aspect, in a possible implementation, the interface module includes a sending module and a receiving module, which are respectively used to implement the sending and receiving functions in any of the above aspects and any possible implementations thereof.

[0021] In a third aspect, a communication device is provided, comprising: a processor coupled to a memory, configured to read instructions from the memory and execute the method according to any of the above-mentioned aspects.

[0025] In conjunction with the fourth aspect above, in one possible implementation, the communication device is a chip or a chip system. Optionally, when the communication device is a chip system, it can be composed of a chip or include a chip and other discrete devices.

[0041] Currently, wireless headsets can have multiple antennas, each with different polarity orientations, for receiving signals of different polarities to ensure the quality of communication between the headset and the terminal. For example, a dual-antenna wireless headset, as shown in Figure 1A, has two antennas with orthogonal polarities: one horizontal and one vertical. Furthermore, the two antennas of the wireless headset can also have other polarities, without limitation.

[0042] The polarity of the antenna can be understood in conjunction with FIG. 1B and FIG. 1C .

[0043] In Figure 1B, the transmitting antenna sends a signal to the receiving antenna. The sinusoidal waveform represents the electric field of the signal, measured in volts. Because both the transmitting and receiving antennas have perpendicular polarity, the receiving antenna experiences minimal energy loss and higher signal quality.

[0044] As shown in Figure 1C, the difference between Figure 1C and Figure 1B is that the polarity of the transmitting antenna and the receiving antenna do not match. The transmitting antenna is vertical, while the receiving antenna is more horizontal. This results in significant energy loss in the signal reaching the receiving end, and the signal quality at the receiving end may be low. When the receiving signal quality is low, it is more susceptible to noise, and the decoded data may have significant errors compared to the original data, making it impossible to accurately restore the original data. Consequently, the audio frame fails to be received.

[0045] Alternatively, multiple antennas can be designed according to the antenna radiation direction of the wireless headset. Taking a wireless headset including dual antennas (such as antenna 1 and antenna 2) as an example, the radiation direction of antenna 1 points to the front of the body, which is used in the scenario where the mobile phone is placed in the user's front pocket, and the radiation direction of antenna 2 points to the back of the body, which is used in the scenario where the mobile phone is placed in the user's back pocket. The wireless headset will select the antenna with better signal reception quality based on the radiation directions of antenna 1 and antenna 2. When the wireless headset radiates a signal to the terminal, the direction of the terminal does not match the radiation direction of the wireless headset, and the wireless headset fails to send the signal. For example, when the terminal sends an audio frame to the wireless headset, but the wireless headset always fails to send, and the terminal does not receive a response from the wireless headset for a certain period of time, the terminal can retransmit the audio frame, or the terminal can also confirm that the connection is disconnected and prompt the user to reconnect.

[0046] Specifically, the process of wireless headset sending and receiving audio frames can refer to the following steps, as shown in Figure 1D. In which, the terminal and the wireless headset are connected.

[0047] S101: The terminal sends an audio frame 1 to the wireless headset. Correspondingly, the wireless headset receives the audio frame 1 from the terminal.

[0048] S102: The wireless headset successfully receives audio frame 1.

[0049] As can be understood, when the wireless headset receives a good signal, it completes verification of the received audio frame 1, indicating successful reception of the audio frame 1. The verification may include a cyclic redundancy check (CRC) or other verification methods. After successfully receiving the audio frame 1, the wireless headset may play the audio content of the audio frame 1 to the user through the speaker.

[0050] S103: The wireless headset sends an acknowledgement (ACK) to the terminal. Correspondingly, the terminal receives the ACK from the wireless headset.

[0051] It can be understood that ACK is used to indicate that the terminal successfully receives audio frame 1. Since the terminal sends different audio frames periodically, after receiving ACK, the terminal will send the next audio frame, that is, audio frame 2, after a period of time.

[0052] S104: The terminal sends audio frame 2 to the wireless headset. Correspondingly, the wireless headset receives audio frame 2 from the terminal.

[0053] S105: The wireless headset fails to receive audio frame 2.

[0054] It is understandable that when the quality of the wireless headset receiving signal is relatively poor, the data of the received audio frame 2 is likely to be erroneous. The data error will cause the received verification failure, such as CRC failure. At this time, it will be considered that the reception of audio frame 2 has failed, and the wireless headset needs to resend audio frame 2.

[0055] S106: The wireless headset sends a negative acknowledgement (NACK) to the terminal. Correspondingly, the terminal receives the NACK from the wireless headset.

[0056] S107: The terminal retransmits the audio frame 2 to the wireless headset. Correspondingly, the wireless headset receives the retransmitted audio frame 2 from the terminal.

[0057] In order to ensure the integrity of the audio, after receiving the NACK, the terminal will try to retransmit the audio frame 2 to the wireless headset so that the wireless headset can obtain the audio content included in the audio frame 2.

[0058] S108: The wireless headset successfully receives audio frame 2.

[0059] It is understandable that if the wireless headset fails to receive the audio frame 2, it can still send a NACK to the terminal to request the terminal to retransmit the audio frame 2 again.

[0060] S109: The wireless headset sends an ACK to the terminal. Correspondingly, the terminal receives the ACK from the wireless headset.

[0061] It is understandable that when the retransmission of audio frame 2 also fails to be received, and before the next initial transmission audio frame (such as audio frame 3) arrives, the terminal can still be instructed to continue retransmission through NACK. If the maximum number of retransmissions is reached or the sending time of audio frame 3 is reached, audio frame 2 needs to be discarded.

[0062] It is understandable that when the polarity of the wireless headset antenna does not match the polarity of the received signal (for example, the polarities of the two are orthogonal), the received signal strength indicator (RSSI) of the signal received by the wireless headset antenna will be very small, resulting in a high packet error rate (PER) of the wireless headset receiving data. In the process described in Figure 1D above, when multiple retransmissions still fail to receive, in order not to affect the reception of the next audio frame, the terminal will no longer retransmit to the wireless headset when the maximum number of retransmissions of the audio frame is reached. This causes the loss of audio frames, thereby affecting the sound quality heard by the user when using the wireless headset. Conversely, when the antenna polarity matches the polarity of the received signal, the signal transmission quality is high and supports a higher transmission rate. At this time, the wireless headset can provide users with better sound quality. Therefore, compared to wireless headsets with a single antenna, wireless headsets with multiple antennas can select an antenna that is more consistent with the polarity of the received signal from multiple antennas to receive the signal, thereby improving the user experience. In addition, when the radiation direction of the wireless headset does not cover the location of the terminal, the signal quality received by the terminal from the wireless headset is very poor, which will affect the terminal's ability to send audio frames to the wireless headset, affecting the user experience. Conversely, when the radiation direction of the wireless headset is directed toward the terminal, the signal transmission quality is higher, providing users with better sound quality. Multi-antenna wireless headsets can select a radiation antenna that can better point to the terminal location from multiple antennas, thereby improving the user experience. Therefore, combined with the above-mentioned process of wireless headsets sending and receiving audio frames, when the wireless headset uses a certain antenna to receive a signal and fails to receive audio, it can switch to another antenna.

[0063] In actual scenarios, after the wireless headset is successfully connected to the terminal (such as a mobile phone, the mobile phone is used as an example below), the user may move the mobile phone, which will cause the wireless channel between the wireless headset and the mobile phone to change, and the polarity relationship between the signal received by the wireless headset and the wireless headset antenna will change. For example, the polarity relationship changes from consistent polarity to inconsistent polarity, and the energy loss of the signal received by the wireless headset becomes larger, which will cause the reception signal quality of the current receiving antenna of the wireless headset to deteriorate. The user moving the mobile phone may also cause the radiation direction of the wireless headset to no longer point to the terminal, and the signal transmission quality between the wireless headset and the terminal deteriorates. Therefore, the wireless headset needs to continuously detect the signal reception quality of multiple antennas, and select the antenna with the best (or better) signal reception quality under the current wireless channel conditions from multiple antennas for reception to ensure the communication quality with the mobile phone.

[0064] Currently, multi-antenna wireless headsets can communicate with a terminal using only one antenna at a time. To measure the signal quality of antennas other than the current one, the headset must switch the antenna used to communicate with the terminal. Poor signal quality from the other antennas can affect the headset's ability to receive audio frames from the terminal, resulting in a poor user experience. Avoiding the risk of poor signal quality after switching antennas can also lead to missed opportunities to select a better antenna and underutilize the benefits of the headset's multiple antennas.

[0065] To address the aforementioned technical issues, the present application provides a signal detection method for wireless headphones. This method can be performed by headphones equipped with multiple antennas. In this method, the headphones can receive a first signal frame via a first antenna. Upon successful reception of the first signal frame, the headphones switch from the first antenna to a second antenna to detect the signal quality of the second antenna. Subsequently, the headphones can receive a second signal frame via a target antenna. The second signal frame is the next initially transmitted signal frame following the first signal frame, and the target antenna is the antenna with the best signal quality between the first and second antennas.

[0066] It can be seen from the above method that since the wireless headset detects the signal quality of the second antenna before receiving the next initial transmission signal frame of the first signal frame after successfully receiving the first signal frame, this method neither affects the playback of the first signal frame nor affects the reception of the next initial transmission signal frame of the first signal frame, thereby maximizing the user experience.

[0098] In this application, “multiple” can be understood as two or more. For example, “a wireless headset has multiple antennas” can be understood as a wireless headset having two or more antennas.

[0099] It is understood that some optional features in this application may, in certain scenarios, be implemented independently of other features, such as the solution on which they are currently based, to solve corresponding technical problems and achieve corresponding effects. They may also be combined with other features in certain scenarios as needed. Accordingly, the devices provided in this application may also implement these features or functions accordingly, which will not be described in detail here.

[0100] It is understandable that the same step or steps or technical features with the same function in different embodiments of the present application can be referenced to each other.

[0101] It is understood that in this application, the wireless headset can perform some or all of the steps in this application. These steps are only examples, and this application can also perform other steps or variations of various steps. In addition, the steps can be performed in a different order than presented in this application, and it is possible that not all steps in this application need to be performed.

[0102] It is understood that the method provided below in this application uses a wireless headset as an example to illustrate the method, but this application does not limit the execution subject of the interaction diagram. For example, the wireless headset in the method provided in the following embodiments of this application can also be a chip, chip system, or processor that supports the wireless headset to implement the method, or it can be a logical node, logic module, or software that can implement all or part of the functions of the wireless headset.

[0103] As shown in FIG4 , a signal detection method for a wireless headset provided by the present application may include the following steps:

[0104] S401: The terminal sends a first signal frame to the wireless headset. Correspondingly, the wireless headset receives the first signal frame from the terminal via the first antenna.

[0105] In the present application, the wireless headset may be the wireless headset 201 in the communication system 20 shown in FIG2A , and the terminal may be the terminal 202 in the communication system 20 shown in FIG2A . Alternatively, the wireless headset may be the wireless headset 211 in the communication system 21 shown in FIG2B , and the terminal may be the terminal 212 in the communication system 21 shown in FIG2B .

[0106] It can be understood that the content carried by the signal frame includes audio data, and the audio data can be played by the speaker of the wireless headset after audio decoding.

[0107] Optionally, the wireless headset may determine the signal quality of the first antenna based on the first signal frame, such as by determining the signal quality of the first antenna based on the RSSI of the first signal frame. Alternatively, the signal quality of the first antenna may be determined based on a combination of multiple signal frames received by the first antenna, such as by determining the signal quality of the first antenna based on the first signal frame and at least one signal frame prior to the first signal frame. This is not limited to the above.

[0108] S402: When the wireless headset successfully receives the first signal frame, it switches from the first antenna to the second antenna and detects the signal quality of the second antenna.

[0109] In the present application, the polarity direction of the first antenna is different from the polarity direction of the second antenna, and signals with different polarity directions can be received. Taking a dual-antenna wireless headset as an example, the first antenna and the second antenna can be built into the dual-antenna wireless headset, with the first antenna being a horizontal polarity antenna and the second antenna being a vertical polarity antenna, or the first antenna being a vertical polarity antenna and the second antenna being a horizontal polarity antenna. Alternatively, the radiation direction of the first antenna is different from the radiation direction of the second antenna, and the two antennas can radiate signals in different directions. Still taking the dual-antenna wireless headset as an example, the first antenna can point to the front of the body and the second antenna can point to the back of the body, or the first antenna can point to the back of the body and the second antenna can point to the front of the body.

[0110] As can be understood, since the wireless headset successfully receives the first signal frame, it can play the audio data carried by the first signal frame. Furthermore, the wireless headset can switch from the first antenna to the second antenna to test the signal quality of the second antenna. This allows the wireless headset to test the signal quality of the second antenna while maintaining playback of the audio data carried by the first signal frame.

[0111] It is understandable that the wireless headset can detect the signal quality of the second antenna through various methods. The following describes the following methods 1 and 2 as examples.

[0112] Method 1: The wireless headset uses a retransmitted signal frame of the first signal frame to determine the signal quality of the second antenna.

[0113] In one possible implementation, upon successfully receiving a first signal frame, the wireless headset sends a first response message indicating that reception of the first signal frame failed. It is understood that the first response message may trigger the terminal to retransmit the first signal frame to the wireless headset. The terminal then sends a third signal frame to the wireless headset. In response, the wireless headset receives the third signal frame via a second antenna and determines the signal quality of the second antenna based on the third signal frame. The third signal frame is a retransmitted signal frame of the first signal frame.

[0114] Optionally, the wireless headset can use the first antenna to send the first response information, or switch from the first antenna to the second antenna and use the second antenna to send the first response information, without limitation. It can be understood that the wireless headset can indicate the reception status of the first signal frame through the automatic repeat request number (ARQN) bit carried in the empty type (NULL) frame. For example, when the first reception of the first signal frame fails, the ARQN bit can be 0001; when the first reception of the first signal frame is successful, the ARQN bit can be 0000; when the second reception of the first signal frame (i.e., receiving the first retransmitted signal frame of the first signal frame) fails, the ARQN bit can be 0002, and so on. It can be seen that the wireless headset can determine the ARQN bit included in the first response information to be 0001.

[0115] Exemplarily, the wireless earphone can determine the signal quality of the second antenna according to the RSSI corresponding to the received third signal frame. Wherein, the unit of RSSI can be decibel milliwatt (dBm). Specifically, when -70dBm < RSSI, the signal quality of the second antenna can be determined to be excellent; when -80dBm < RSSI < -70dBm, the signal quality of the second antenna can be determined to be good; when -90dBm < RSSI < -80dBm, the signal quality of the second antenna can be determined to be medium; when -100dBm < RSSI < -90dBm, the signal quality of the second antenna can be determined to be poor; when RSSI < -100dBm, the signal quality of the second antenna can be determined to be extremely poor.

[0116] It can be understood that the above is only an example of the wireless earphone determining the signal quality of the second antenna. In specific applications, the wireless earphone can also determine the signal quality of the second antenna according to other parameters characterizing the signal quality. For example, the wireless earphone can determine the signal quality of the second antenna according to PER, or determine the signal quality of the second antenna according to RSSI and PER.

[0117] Optionally, in the case where the reception of the third signal frame fails, the wireless earphone sends a second response message to the terminal. Wherein, the second response message indicates that the third signal frame is received successfully. It can be understood that the third signal frame is a retransmission signal frame of the first signal frame, which is used to determine the signal quality of the second antenna of the wireless earphone and is the same as the audio data carried by the first signal frame. When the first signal frame is successfully received, the audio data carried by the first signal frame can already be played by the speaker of the wireless earphone. The reception result of the third signal frame will not affect the audio playback of the wireless earphone. Therefore, when the reception of the third signal frame fails, it can no longer be retransmitted. Thus, the signal quality of the second antenna is obtained without affecting the user experience.

[0118] It is understandable that in order to improve the accuracy of detecting the signal quality of the second antenna, the wireless headset can trigger the terminal to retransmit the first signal frame multiple times. In this way, the wireless headset can determine the signal quality of the second antenna based on the multiple received retransmitted signal frames. Specifically, after receiving the third signal frame, the wireless headset can send a fourth response message to the terminal. The fourth response message indicates that the third signal frame failed to be received. For example, the fourth response message can be a negative acknowledgement (NACK). Therefore, after receiving the fourth response message, the terminal can send a retransmitted signal frame of the first signal frame to the wireless headset, such as the fourth signal frame. After receiving the fourth signal frame, the wireless headset can send a negative acknowledgement (NACK) or an acknowledgement (ACK) to the terminal. If the wireless headset sends an ACK, the terminal will stop retransmitting, and the wireless headset can determine the signal quality of the second antenna based on the third and fourth signal frames. If the wireless headset sends a negative acknowledgement (NACK), the terminal will continue to send retransmitted signal frames of the first signal frame to the wireless headset, and the wireless headset can determine the signal quality of the second antenna based on more retransmitted signal frames.

[0119] It is understandable that the terminal usually periodically sends signal frames to the wireless headset. Therefore, in order to ensure the user experience, the process of the wireless headset receiving the retransmitted signal frame of the first signal frame can be performed before the arrival of the next initially transmitted signal frame of the first signal frame. For example, if the terminal sends signal frames according to a period T, the terminal can send signal frame 1 at time t0, send signal frame 2 at time (t0+T), send signal frame 3 at time (t0+2T), etc., if the first signal frame is signal frame 1, the wireless headset can detect the signal quality of the second antenna in the above manner after successfully receiving signal frame 1 and before receiving signal frame 2.

[0120] Taking T equal to 500ms as an example, as shown in Figure 5, the terminal can send the first signal frame at time 501, send the first retransmission signal frame (such as the third signal frame) corresponding to the first signal frame at time 502, send the second retransmission signal frame (such as the fourth signal frame) corresponding to the first signal frame at time 503, send the third retransmission signal frame (such as the fifth signal frame) corresponding to the first signal frame at time 504, and send the initial transmission signal frame after the first signal frame (such as the second signal frame) at time 505. Among them, the initial transmission signal frame means that the audio data carried by the signal frame is transmitted for the first time. The transmission period of the initial transmission signal frame can be 500ms, that is, the time interval between time 505 and time 501 is 500ms. Of course, it can also be other durations without limitation.

[0121] In conjunction with Figure 5, the wireless headset can determine the signal quality of the second antenna based on the reception quality of multiple retransmitted signal frames of the first signal frame, namely the third signal frame, the fourth signal frame and the fifth signal frame, and before the arrival of time 505, determine the signal quality of the second antenna based on more retransmitted signal frames of the first signal frame. This can eliminate the influence of accidental factors. Compared with the result of the signal quality of the second antenna obtained based on one retransmitted signal frame, the result of the signal quality of the second antenna obtained based on multiple retransmitted signal frames can be more accurate.

[0122] Method 2: The wireless headset determines the signal quality of the second antenna based on the response frame corresponding to the detection frame. The detection frame can be used to detect the connection status between the wireless headset and the terminal.

[0123] In method 2, the wireless headset can send a first detection frame through the second antenna, receive a first response frame through the second antenna, and determine the signal quality of the second antenna based on the first response frame. The first response frame is used to indicate that the first detection frame has been received. The first detection frame can be a connection status detection frame (such as a polling (POLL) frame). The wireless headset can initiate a wireless connection status detection to the terminal through the first detection frame. If the terminal successfully receives the first detection frame, it means that the terminal's reception is normal. The terminal can reply to the wireless headset with a first response frame (such as a NULL frame). The wireless headset receives the first response frame, which means that the connection between the wireless headset and the terminal is normal.

[0124] In one possible implementation, the wireless headset can determine the signal quality of the second antenna based on the RSSI and / or PER corresponding to the first response frame. For details, please refer to the method in Method 1 where the wireless headset determines the signal quality of the second antenna based on the third signal frame, which will not be repeated here.

[0125] It can be understood that the purpose of the wireless headset initiating connection status detection is to obtain the signal quality of the second antenna in the idle time before the next initial transmission signal frame (such as the second signal frame) of the first signal frame, and it will not affect the reception of the second signal frame.

[0126] As will be appreciated, to improve the accuracy of detecting the second antenna's signal quality, the wireless headset can trigger the terminal to send multiple response frames. In this way, the wireless headset can determine the second antenna's signal quality based on the multiple response frames. Specifically, after receiving the first response frame, the wireless headset can send a second detection frame to the terminal, prompting the terminal to send a second response frame to the wireless headset. Therefore, after receiving the second response frame, the wireless headset can determine the second antenna's signal quality based on the first and second response frames.

[0127] S403: The terminal sends a second signal frame to the wireless headset. Correspondingly, the wireless headset receives the second signal frame from the terminal via the target antenna.

[0128] In one possible implementation, the wireless headset determines the antenna with the best signal quality as the target antenna based on the signal quality of the first and second antennas. For example, if the RSSI of the received signal corresponding to the first antenna is -80dBm and the RSSI of the received signal corresponding to the second antenna is -60dBm, the wireless headset may determine the second antenna as the target antenna. It should be understood that if the wireless headset has more than two antennas, the antenna with the best signal quality may be selected as the target antenna based on the signal quality of each antenna.

[0129] It should be understood that because the position of the terminal is changing, the wireless channel may be time-varying, and the polarity relationship between the wireless headset and the terminal may also change. Therefore, after the wireless headset successfully establishes a connection with the terminal, the above methods S401 to S403 can be repeated to update the target antenna at any time to ensure that the wireless headset uses the antenna with the best signal quality, thereby ensuring the user experience. Alternatively, because the position of the terminal is changing, the wireless headset needs to switch the antenna to communicate with the terminal using an antenna whose radiation direction is consistent with the terminal position to improve the communication quality. Therefore, after the wireless headset successfully establishes a connection with the terminal, the above methods S401 to S403 can be repeated to update the target antenna at any time to ensure that the wireless headset uses an antenna that radiates towards the terminal, thereby ensuring the user experience.

[0130] According to the above method, after successfully receiving a signal frame (such as the first signal frame), the wireless headset can use the period before the arrival of the next initial transmission signal frame of the signal frame (such as the second signal frame) to request at least one data transmission from the terminal (the data can be a retransmission signal frame of the first signal frame in method 1, or the first response frame in method 2, etc.) to detect the signal quality of the second antenna and determine the target antenna for receiving the second signal frame. Because the process of the wireless headset determining the signal quality of the second antenna is performed before the arrival of the second signal frame, the audio data of the first signal frame can be played through the speaker of the wireless headset during this period. Therefore, the reception status (success or failure) of the retransmission signal frame received by the second antenna will not affect the sound quality heard by the user through the speaker, thereby achieving the measurement of the signal quality of other antennas without affecting the user experience.

[0131] The above mainly introduces the solution provided by the present application from the perspective of the interaction between the wireless headset and the terminal. Accordingly, the present application also provides a communication device, which can be the wireless headset in the above method embodiment, or a device including the above wireless headset, or a component that can be used for the wireless headset. It can be understood that in order to achieve the above functions, the above wireless headset includes a hardware structure and / or software module corresponding to the execution of each function. Those skilled in the art should easily realize that, in combination with the units and algorithm operations of the various examples described in the embodiments disclosed herein, the present application can be implemented in the form of hardware or a combination of hardware and computer software. Whether a function is executed in hardware or by computer software driving hardware depends on the specific application and design constraints of the technical solution. Professional and technical personnel can use different methods to implement the described functions for each specific application, but such implementation should not be considered to be beyond the scope of this application.

[0132] The present application can divide the functional modules of the wireless headset according to the above method example. For example, each functional module can be divided according to each function, or two or more functions can be integrated into a single processing module. The above integrated modules can be implemented in the form of hardware or software functional modules. It should be understood that the division of modules in this application is schematic and is only a logical functional division. In actual implementation, other division methods may be used.

[0133] For example, FIG6 shows a schematic diagram of the structure of a communication device 60, where the functional modules are divided in an integrated manner. Communication device 60 includes an interface module 601 and a processing module 602. Interface module 601, also known as an interface unit, is configured to perform transceiver operations and may be, for example, an interface circuit, a transceiver, a transceiver, or a communication interface. Processing module 602, also known as a processing unit, is configured to perform operations other than transceiver operations and may be, for example, a processing circuit or a processor.

[0138] The interface module 601 is further configured to receive a second signal frame through a target antenna, where the second signal frame is the next initially transmitted signal frame after the first signal frame, and the target antenna is the antenna with the best signal quality between the first antenna and the second antenna. For example, the interface module 601 can be configured to execute S403.

[0139] In one possible implementation, interface module 601 is further configured to send a first response message indicating a failure to receive the first signal frame. Processing module 602 is specifically configured to receive a third signal frame via a second antenna, where the third signal frame is a retransmitted signal frame of the first signal frame. Processing module 602 is further specifically configured to determine the signal quality of the second antenna based on the third signal frame.

[0140] In a possible implementation, the interface module 601 is further configured to send second response information when the third signal frame fails to be received, where the second response information indicates that the third signal frame is successfully received.

[0141] In one possible implementation, the processing module 602 is specifically configured to send a first detection frame through the second antenna; the processing module 602 is further specifically configured to receive a first response frame through the second antenna, where the first response frame is used to indicate receipt of the first detection frame; and the processing module 602 is further specifically configured to determine a signal quality of the second antenna based on the first response frame.

[0142] In one possible implementation, processing module 602 is further configured to play the audio data carried by the first signal frame. In a simple embodiment, those skilled in the art will appreciate that communication device 60 may adopt the form shown in FIG3 . For example, processor 301 in FIG3 may invoke computer-executable instructions stored in memory 303 to cause communication device 60 to execute the method described in the above embodiment.

[0143] Exemplarily, the functions / implementation processes of the interface module 601 and the processing module 602 in FIG6 can be implemented by the processor 301 in FIG3 calling computer-executable instructions stored in the memory 303.
