[0002] In practical applications, headphones can generally be divided into wired headphones and wireless headphones. Since wired headphones are inconvenient to wear, wireless headphones are favored by more and more users. Among them, wireless headphones include True Wireless Stereo (TWS) headphones.

[0028] In order to enable a more detailed understanding of the features and technical contents of the embodiments of the present application, the implementation of the embodiments of the present application is described in detail below in conjunction with the accompanying drawings. The attached drawings are for reference only and are not used to limit the embodiments of the present invention.

[0029] It should be noted that the terms "first", "second", etc. in the specification and claims of the present application and the above-mentioned drawings are used to distinguish different objects, rather than to describe a specific order. In addition, the terms "including" and "having" and any of their variations are intended to cover non-exclusive inclusions. For example, a process, method, system, product or device that includes a series of steps or units is not limited to the listed steps or units, but optionally includes steps or units that are not listed, or optionally includes other steps or units inherent to these processes, methods, products or devices. "Multiple" in this application means two or more situations; "and / or" describes the association relationship of associated objects, indicating that three relationships can exist, for example, A and / or B can represent: A exists alone, A and B exist at the same time, and B exists alone. The character " / " generally indicates that the objects associated before and after are in an "or" relationship. The step numbers in this application are only used for example, and may correspond to different implementation methods. In the absence of conflict, their order is not limited. The technical features in the embodiments and implementation methods provided in this application can be combined with each other in the absence of conflict.

[0030] refer to Figure 1 A schematic diagram of the architecture of a wireless headset RF module in a related technology is shown in FIG. Figure 1 As shown, the RF module of the wireless headset is usually composed of a main control chip 11, a filter 12, a matching circuit 13 and an antenna 14. The RF signal is output by the RF port of the main control chip 11, transmitted to the filter 12 through a transmission line, and then transmitted to the antenna 14 through a Π-shaped matching circuit 13, and then transmitted to the air through the antenna 14.

[0031] Currently, the popular TWS earphones need to be paired with the left and right earphones. The two earphones need to communicate with each other and with the playback device (i.e., the terminal device). In actual situations, the link loss of the first communication link between the two earphones and the link loss of the second communication link between the earphones and the terminal device are different. However, in the related art, such as Figure 1 As shown in the figure, there is only one RF antenna system on the TWS headset. To achieve compatibility in the two communication modes, some performance will be lost. If, in order to overcome the loss of the headphone signal when passing through the human head, the antenna will be specially designed to ensure the signal strength through the head, then the signal strength between the terminal device and the headset may be reduced. Therefore, to achieve compatibility in the above two communication links, the use of a single antenna solution will inevitably lose some performance, resulting in weaker transceiver capabilities of wireless headsets.

[0032] In addition, wireless headphones use a single-antenna RF architecture for data transmission. However, the radiation pattern of the antenna in the single-antenna architecture is fixed. At certain specific angles, the radiation power of the antenna will be relatively low, and when the terminal device is at this specific angle, the signal quality received by the antenna is poor. In addition, the main control chip in the single-antenna structure can only process one signal, and when it is affected by the multipath effect or encounters strong interference, it is easy to cause data packet loss.

[0033] Based on the problems in the related art, an embodiment of the present application provides a data transmission method, which can be applied to a first wireless headset in a pair of wireless headsets worn on both ears. Among them, the first wireless headset can be configured with multiple antenna units, so that the first wireless headset can use a first antenna unit set composed of at least some of the multiple antenna units to communicate with the second wireless headset. And / or, the first wireless headset can use a second antenna unit set composed of at least some of the multiple antenna units to communicate with a terminal device. In this way, data transmission can be carried out in a variety of forms under multiple antennas, which improves the data transmission and reception capabilities of the wireless headset in compatible ear-to-ear communication (communication between the first wireless headset and the second wireless headset) and terminal communication (communication between at least one headset in a pair of headsets and a terminal device) modes.

[0034] It is worth noting that in the embodiments of the present application, the first wireless headset can implement the above data transmission method through various hardware logic circuits in conjunction with software codes.

[0035] It should be noted that the first wireless headset can be any one of a pair of wireless headsets suitable for wearing on both ears. That is to say, in the embodiment of the present application, any single headset has multiple antenna units and transmits data through multiple antenna units. Here, the multiple antenna units include at least two antenna units; that is, the first wireless headset may include two or more antenna units.

[0036] In the embodiments provided in the present application, the first wireless headset may be a Bluetooth headset, that is, a headset that transmits stereo signals via Bluetooth communication technology. The first wireless headset may also be a headset that uses other short-range wireless communication technologies, such as a headset that uses WiFi communication technology. The embodiments of the present application do not limit the type of wireless headset.

[0037] In addition, the terminal device mentioned in the embodiment of the present application may be a playback device paired with the first wireless headset. The terminal device may be a smart phone, a tablet computer, a personal computer, a wearable device, and the like.

[0038] The technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application.

[0039] An embodiment of the present application provides a data transmission method, which can be applied to a first wireless headset in a pair of wireless headsets, wherein the first wireless headset includes a plurality of antenna units. Figure 2 A data transmission method flow chart is shown, the method comprising:

[0040] Step 210: The first wireless headset performs data transmission with the second wireless headset through a first antenna unit set among the plurality of antenna units; the second wireless headset is another wireless headset in a pair of wireless headsets except the first wireless headset;

[0041] and / or,

[0042] The first wireless headset performs data transmission with the terminal device through a second antenna unit set among the multiple antenna units; the first antenna unit set and the second antenna unit set are the same or different.

[0043] In the embodiment of the present application, the first antenna unit set may include at least one antenna unit among the above-mentioned multiple antenna units. That is, the first antenna unit set may include all antenna units in the first wireless headset, or may include some antenna units in the first wireless headset. The embodiment of the present application does not limit the number of antenna units included in the first antenna unit set.

[0044] Similarly, the second antenna unit set may include at least one antenna unit among the above-mentioned multiple antenna units. That is to say, the second antenna unit set may include all antenna units in the first wireless headset, or may include some antenna units in the first wireless headset. The embodiment of the present application does not limit the number of antenna units included in the second antenna unit set.

[0045] In addition, in the embodiment of the present application, the first antenna unit set and the second antenna unit set may be the same or different.

[0046] Among them, the first antenna unit set is the same as the second antenna unit set, which can be understood as the antenna units included in the first antenna unit set are the same as the antenna units included in the second antenna unit set. It should be noted that when the first antenna unit set is the same as the second antenna unit set, the first antenna unit set and the second antenna unit set may include multiple antenna units, that is, the first wireless headset uses the same multiple antenna units to transmit data with the second wireless headset and the terminal device respectively. Exemplarily, the first wireless headset includes two antenna units, and the first wireless headset transmits data with the second wireless headset through the two antenna units, and the first wireless headset can also transmit data with the terminal device through the two antenna units. Here, the first wireless headset can use the same antenna unit in a time division multiplexing manner to transmit data with the second wireless headset and the terminal device respectively.

[0047] In addition, the first antenna unit set is different from the second antenna unit set, and may include: the antenna units included in the first antenna unit set are all different from the antenna units included in the second antenna unit set; or the antenna units included in the first antenna unit set are different from the antenna units included in the second antenna unit set. The embodiments of the present application do not limit this. Exemplarily, the first wireless headset includes two antenna units, namely antenna unit 1 and antenna unit 2. The first wireless headset transmits data with the second wireless headset through antenna unit 1, and the first wireless headset transmits data with the terminal device through antenna unit 2.

[0048] It can be seen that in the embodiment of the present application, the first wireless headset can be configured with multiple antenna units, so that the first wireless headset can use a first antenna unit set composed of at least some of the multiple antenna units to communicate with the second wireless headset. And / or, the first wireless headset can also use a second antenna unit set composed of at least some of the multiple antenna units to communicate with the terminal device. In this way, multiple forms of data transmission can be used under multiple antennas, which improves the data transmission and reception capabilities of the wireless headset in compatible ear-to-ear communication (communication between the first wireless headset and the second wireless headset) and terminal communication (communication between at least one headset in a pair of headsets and the terminal device) modes.

[0049] In an embodiment of the present application, when the first antenna unit set and the second antenna unit set are the same, step 210 performs data transmission with the second wireless headset through the first antenna unit set among the multiple antenna units, and performs data transmission with the terminal device through the second antenna unit set among the multiple antenna units, which can be implemented by the following steps:

[0050] Step 210a, at a first moment, controlling the first antenna unit set to perform data transmission with the second wireless headset; and, at a second moment, controlling the second antenna unit set to perform data transmission with the terminal device; the first moment and the second moment are different.

[0051] It is understandable that the first wireless headset can use the same set of antenna units to communicate with the second wireless headset and the terminal device respectively in a time division multiplexing manner. That is, the first wireless headset uses the same set of antenna units at different time sequences to communicate with different data transmission objects; wherein different data transmission objects have different corresponding time sequences.

[0052] Exemplarily, when the current timing is the binaural communication timing, the first wireless headset controls each antenna in the first antenna unit set to communicate with the second wireless headset. When the current timing is the headset-to-terminal device communication timing, the first wireless headset controls each antenna unit in the second antenna unit set to communicate with the terminal device.

[0053] In this way, the data transmission method provided in the embodiment of the present application uses multiple antenna units to communicate with different data transmission objects, thereby improving the flexibility of the wireless headset in transmitting data to different data transmission objects.

[0054] In another embodiment of the present application, when the antenna units included in the first antenna unit set are different from the antenna units included in the second antenna unit set, data transmission is performed with the second wireless headset through the first antenna unit set among the multiple antenna units in step 210, and data transmission is performed with the terminal device through the second antenna unit set among the multiple antenna units. The following steps can be implemented:

[0055] Step 210b: at a third moment, control the first antenna unit set to perform wireless communication with the second wireless headset, and control the second antenna unit set to perform wireless communication with the terminal device.

[0056] It can be understood that when the first antenna unit set and the second antenna unit set include different antennas, the first wireless headset can use different antenna unit sets to transmit data with the second wireless headset and the terminal device at the same time.

[0057] Exemplarily, the first wireless headset is configured with four antenna units, specifically antenna units 1 to 4. The first wireless headset can use antenna units 1 and 2 to transmit data to the second wireless headset, and use antenna units 3 and 4 to transmit data to the terminal device.

[0058] In this way, the data transmission method provided in the embodiment of the present application can communicate with different data transmission objects respectively through two completely different antenna unit sets among the multiple antenna units, thereby increasing the data transmission rate.

[0059] Based on the foregoing embodiment, in another embodiment of the present application, when the first antenna unit set is different from the second antenna unit set, the radiation direction of the first antenna unit in the first antenna unit set is adapted to the wireless transmission when the first wireless headset and the second wireless headset are in a wearing state; the first antenna unit is any antenna unit in the first antenna unit set that is different from the second antenna unit set;

[0060] and / or,

[0061] The radiation direction of the second antenna unit in the second antenna unit set is adapted to the wireless transmission between the first wireless headset and the terminal device; the second antenna unit is any antenna unit in the second antenna unit set that is different from the first antenna unit set.

[0062] In the embodiment of the present application, the multiple antenna units in the first wireless headset can be designed with different focuses, that is, different antenna units focus on supporting the binaural communication mode and the terminal communication mode respectively.

[0063] Specifically, when the first antenna unit set is different from the second antenna unit set, the first antenna unit set is used to transmit the radio frequency signal required for binaural communication, that is, the antenna units in the first antenna unit set can focus on data transmission between the second wireless headset. The second antenna unit set is used to transmit the radio frequency signal for the first wireless headset to communicate with the terminal device, that is, the antenna units in the second antenna unit set can focus on data transmission between the terminal device.

[0064] Based on this, some antenna units in the first antenna unit set can be designed to be specifically used to enhance the radiation direction of the head-penetrating signal. Specifically, the radiation direction of the first antenna unit in the first antenna unit set can be designed to adapt to the wireless transmission between the first wireless headset and the second wireless headset. Here, the wireless transmission between the first wireless headset and the second wireless headset generally refers to the wireless transmission between the two wireless headsets when the user wears the two wireless headsets.

[0065] Here, the first antenna unit is any antenna unit in the first antenna unit set that is different from all antenna units in the second antenna unit set. It can be understood that if the first antenna unit set and the second antenna unit set are completely different, all antenna units in the first antenna unit set can be designed to be dedicated to enhancing the radiation direction of the through-the-head signal. If the first antenna unit set and the second antenna unit set are only partially different, the antenna units in the first antenna unit set that are different from the second antenna unit set are designed to be dedicated to enhancing the radiation direction of the through-the-head signal.

[0066] In addition, some antenna units in the second antenna unit set can also be set to be specifically used to enhance the radiation direction of the communication between the terminal device and the first wireless headset. Specifically, the radiation direction of the second antenna unit in the second antenna unit set can adapt to the wireless transmission between the first wireless headset and the terminal device. Exemplarily, the wireless transmission between the first wireless headset and the terminal device can be the wireless transmission between the first wireless headset and the terminal device when the first wireless headset is worn.

[0067] Among them, the second antenna unit is any antenna unit in the second antenna unit set that is different from the antenna units included in the first antenna unit set. It can be understood that if the first antenna unit set and the second antenna unit set are completely different, all antenna units in the second antenna unit set can be designed to be dedicated to enhancing the radiation direction of communication between the terminal device and the first wireless headset. If the first antenna unit set and the second antenna unit set are only partially different, the antenna units in the second antenna unit set that are different from the first antenna unit set are designed to be dedicated to enhancing the radiation direction of communication between the terminal device and the first wireless headset.

[0068] It should be noted that the technician may only design at least part of the antenna units in the first wireless headset to adapt to the wireless transmission between the first wireless headset and the second wireless headset, or only design at least part of the antenna units in the first wireless headset to adapt to the wireless transmission between the first wireless headset and the terminal device, or simultaneously design a part of the antenna units to adapt to the wireless transmission between the first wireless headset and the second wireless headset, and another part of the antenna units to adapt to the wireless transmission between the first wireless headset and the terminal device. The embodiments of the present application are not limited to this.

[0069] In summary, in the data transmission method provided in the embodiment of the present application, the antenna unit of the first wireless headset can be designed with different focuses, thereby improving the flexibility of the first wireless headset and the compatibility of binaural communication and communication between the headset and the terminal device.

[0070] Based on the above embodiments, in one embodiment of the present application, data transmission in step 210 can be implemented in the following manner:

[0071] Step 2101: The first wireless headset controls at least two antenna units among the plurality of antenna units to transmit at least two paths of data; the at least two antenna units correspond to the at least two paths of data one by one, and different antenna units correspond to different paths of data;

[0072] The first antenna unit set includes the at least two antenna units, and / or the second antenna unit set includes the at least two antenna units.

[0073] It can be understood that when the first antenna unit set includes two or more antenna units, the first wireless headset can control at least two antenna units in the first antenna unit set and simultaneously transmit at least two different data to the second wireless headset.

[0074] In a possible implementation, when the first wireless headset detects that the link quality between the two wireless headsets is good, it can control at least two antennas in the first antenna unit set to simultaneously transmit at least two different data paths to increase the data transmission rate between the two headsets.

[0075] In practical applications, the first wireless headset can determine the link quality between the two headsets based on the relevant parameters of the received signal sent by the second wireless headset. For example, when the signal-to-noise ratio of the signal received by the first wireless headset is greater than a certain threshold, it can be determined that the link quality between the two wireless headsets is good.

[0076] In addition, in an embodiment of the present application, when the second antenna unit set includes two or more antenna units, the first wireless headset can control at least two antenna units in the second antenna unit set and simultaneously transmit at least two different data to the terminal device.

[0077] In a possible implementation, when the first wireless headset detects that the link quality between it and the terminal device is good, it can control at least two antennas in the second antenna unit set to simultaneously transmit at least two different data paths to increase the data transmission rate between the first wireless headset and the terminal device.

[0078] Here, the first wireless headset can determine the link quality between the current first wireless headset and the terminal device based on the relevant parameters of the received signal sent by the terminal device. Exemplarily, when the signal-to-noise ratio of the signal received by the first wireless headset is greater than a certain threshold, it can be determined that the link quality between the first wireless headset and the terminal device is good.

[0079] Based on the above embodiment, in another embodiment of the present application, when multiple antenna units have different radiation directions, data transmission in step 210 can be implemented through step 2101' and step 2102'. Specifically,

[0080] Step 2101', controlling at least two antenna units among the multiple antenna units to receive the same transmission signal in radiation directions respectively corresponding to the at least two antenna units, to obtain at least two signals to be processed;

[0081] Among them, at least two antenna units correspond one-to-one to at least two signals to be processed; the first antenna unit set includes the at least two antenna units, and / or the second antenna unit set includes the at least two antenna units.

[0082] It can be understood that when the first antenna unit set includes two or more antenna units, the first wireless headset can control at least two antenna units in the first antenna unit set to receive a transmission signal sent by the second wireless headset in their corresponding radiation directions to obtain at least two signals to be processed, wherein one antenna unit corresponds to one signal to be processed.

[0083] Similarly, when the second antenna unit set includes two or more antenna units, the first wireless headset can also control at least two antenna units in the second antenna unit set to receive a transmission signal sent by the terminal device in their corresponding radiation directions to obtain at least two signals to be processed, wherein one antenna unit corresponds to one signal to be processed.

[0084] It should be noted that the radiation direction of each antenna unit in the multiple antenna units is different, and the interference conditions and link states in different radiation directions are different. Therefore, the signals to be processed received by the antenna units in different radiation directions are also different.

[0085] In the embodiments provided in the present application, the distance between any two antenna units among the multiple antenna units can be set to be greater than a preset distance, that is, the multiple antenna units are physically separated from each other, so as to ensure that the wireless transmission paths of different antenna units are independent of each other, so as to reduce the interference between the signals to be processed received by each antenna unit. Here, the preset distance can be a multiple of the wavelength of the electromagnetic wave in wireless communication.

[0086] Step 2102': determine a target processing signal based on at least two signals to be processed, and demodulate the target processing signal to obtain data carried by the transmission signal.

[0087] In the implementation provided by the application, at least two signals to be processed are received by antenna units with different radiation directions. Different antenna units correspond to different wireless propagation paths, and the same signal experiences different fading in different wireless propagation paths. These fadings are caused by complex reflections from objects near the wireless headset. Fading usually causes the signal strength within a small distance range to follow the Rayleigh fading distribution.

[0088] In practical applications, if a signal in a wireless propagation path experiences deep fading, then the signal transmitted in other relatively independent wireless propagation paths may have stronger signal quality; that is, when the signal received by one antenna unit is drowned out by noise, another antenna unit may receive a stronger signal. Therefore, in order to prevent deep fading from occurring during data transmission and causing the headphone to freeze, spatial diversity technology can be used to process multiple signals to be processed to reduce the impact of fading.

[0089] In the embodiment provided in the present application, the first wireless headset determines the target processing signal based on at least two signals to be processed, which may include: selecting and / or merging the at least two signals to be processed to obtain the target processing signal.

[0090] It should be noted that the signal quality of the target processed signal obtained after selection and / or merging processing (selection processing, or, merging processing, or, selection processing and merging processing) can be greater than or equal to the signal quality of the first signal to be processed among at least two signals to be processed; wherein the first signal to be processed can be the signal to be processed with the highest signal quality among multiple signals to be processed.

[0091] In the embodiment provided in the present application, the target processing signal is determined by the signal to be processed received by the first wireless headset through antennas with different radiation directions. The target processing signal has a strong signal quality. After obtaining the target processing signal, the first wireless headset can directly demodulate the target processing signal to obtain the data carried in the target signal.

[0092] It can be seen that the data transmission method provided in the embodiment of the present application can receive signals to be processed in different radiation directions, and determine a better target processing signal based on multiple signals to be processed, thereby recovering the data carried by the transmitted signal. In this way, the RF connection stability and anti-interference ability of the wireless headset are improved, and the packet loss rate is reduced.

[0093] In the embodiments provided in the present application, the first wireless headset may have a variety of hardware structures, two of which are described in detail below.

[0094] The first hardware structure,

[0095] In the embodiment provided in the present application, the first wireless headset includes multiple antenna units, and different antenna units have different radiation directions; the first wireless headset also includes a first communication circuit and a switching switch; the switching switch is connected to the radio frequency port of the first communication circuit, and the switching switch is used to connect the radio frequency port to the target antenna unit under the control of the first communication circuit; the target antenna unit is any one of the at least two antenna units in step 2101'.

[0096] Here, the first wireless headset has two antenna units as an example for explanation. Figure 3 The hardware structure of a first wireless headset is shown in Fig. 1, where the first wireless headset may include two antenna units: an antenna unit 31 and an antenna unit 32; wherein a radiation direction of the antenna unit 31 is at a preset angle to a radiation direction of the antenna unit 32. The preset angle may be an angle obtained by experimental calculation in advance.

[0097] The first wireless headset further includes a first communication circuit 33 and a switch 34. The first communication circuit 33 has a radio frequency port, through which the first communication circuit 33 is connected to the switch 34; the switch 34 can connect the radio frequency port to the antenna unit 31 or the antenna unit 32 under the control of the first communication circuit 33.

[0098] In the embodiments provided in the present application, the first communication circuit may be a Bluetooth chip or a main control chip for other short-range communications, and may be used to send and receive Bluetooth radio frequency signals or other short-range communication radio frequency signals.

[0099] In addition, the switching switch can be a single-pole multi-throw switch, and the first communication circuit is connected to the input end of the switching switch through the RF port. In addition, the switching switch can be controlled by the communication timing inside the first communication circuit, and the first communication circuit controls the output end of the switching switch to be connected to one of the at least two antenna units mentioned above in different timings.

[0100] It can be understood that in the embodiment of the present application, the first communication circuit has a radio frequency port, and data transmission and reception of multiple antennas are realized through the radio frequency port, thereby improving the utilization efficiency of the first communication circuit.

[0101] In the examples provided in this application, reference is made to Figure 4 The hardware structure of a first wireless headset is shown in FIG. Figure 2 , each antenna unit may include a filter circuit 41, a matching circuit 42 and an antenna 43;

[0102] The first end of the filter circuit 41 is connected to the first end of the matching circuit 42 , the second end of the matching circuit 42 is connected to the antenna 43 ; and the second end of the filter circuit 41 is connected to the switch 34 .

[0103] Here, the matching circuit 42 may be a Π-shaped matching circuit, referring to Figure 4 As shown, the matching circuit 42 is composed of a resistor and two capacitors. The matching circuit 42 is used to transform the impedance so that the antenna radiator and the transmission line are matched to transmit the maximum power. The filter circuit 41 is used to filter out the interference signal in the signal to be processed.

[0104] It is understandable that the switch 34 can be connected to the filter circuit 41 of any antenna unit among the multiple antenna units under the control of the first communication circuit 33. The filter circuit 41 and the matching circuit 42 form a path between the antenna 43 and the RF port of the first communication circuit 33.

[0105] In the embodiment provided in the present application, each antenna unit corresponds to a matching circuit and a filtering circuit, so that each antenna component can be completely separated to reduce interference between the antennas.

[0106] Based on the first hardware composition structure, in the embodiment of the present application, step 2101' controls at least two antenna units among the multiple antenna units, receives the same transmission signal in the radiation directions respectively corresponding to the at least two antenna units, and obtains at least two signals to be processed, which can be implemented in the following manner:

[0107] The control switching switch connects the RF port with the at least two antenna units in a preset order within a preset time period, and when connected with the target antenna unit, receives the transmitted signal in the radiation direction corresponding to the target antenna unit to obtain a signal to be processed corresponding to the target antenna unit, wherein the target antenna unit is one of the at least two antenna units.

[0108] It can be understood that the first wireless headset can be connected to at least two antenna units in the first antenna unit set or the second antenna unit set in a preset order within a preset time period by controlling the connection mode of the switching switch to obtain the signals to be processed received by the at least two antenna units in their radiation directions.

[0109] Here, the preset order may be the arrangement order of the at least two antenna units, or may be the order of the numbers of the at least two antenna units. The embodiment of the present application does not limit the preset order.

[0110] Correspondingly, in step 2102', determining the target processing signal based on at least two signals to be processed can be achieved in the following manner:

[0111] The first wireless headset selects a signal to be processed whose signal quality is greater than a preset threshold from at least two signals to be processed, obtains a target processed signal, and controls the switching switch to connect the radio frequency port to the antenna unit corresponding to the target processed signal.

[0112] In the embodiment provided in the present application, after acquiring at least two signals to be processed, the first wireless headset can detect the signal quality of the at least two signals to be processed; and select a signal to be processed with a larger signal quality from the multiple signals to be processed as the target processing signal. It should be noted that a detection unit can be integrated inside the first wireless headset, and the signal quality of the at least two signals to be processed can be detected by the detection unit.

[0113] Here, the signal quality may include one or more parameters such as signal receiving power, signal strength, signal-to-noise ratio, etc. It is understandable that the first wireless headset may determine the signal receiving power, signal strength, signal-to-noise ratio, etc. of each signal to be processed, thereby determining a signal to be processed with the largest signal receiving power, signal strength, or signal-to-noise ratio from multiple signals to be processed as the target processing signal.

[0114] It is understandable that, due to the different radiation directions of the antenna units, when the signal to be processed received by one antenna unit in its radiation direction is drowned by noise and becomes invalid, the signal quality of the signal to be processed received by another antenna unit in its radiation direction is relatively high. Therefore, by selecting the signal to be processed with relatively high signal quality from at least two signals to be processed as the target processing signal, and demodulating the target processing signal, the target data carried in the target processing signal can be accurately restored, thereby reducing the packet loss rate during data transmission.

[0115] Furthermore, after determining the target processing signal, it can be considered that the link quality between the antenna unit corresponding to the target processing signal and the data transmitting end (including the second wireless headset and / or the terminal device) is good, and the link quality between other antenna units and the data transmitting end is poor. Therefore, the first wireless headset can control the switch to connect the RF port to the antenna unit corresponding to the target processing signal, and transmit data through the antenna unit. In this way, the RF connection stability and anti-interference ability of the first wireless headset are improved, as well as the wireless connection distance of the first wireless headset.

[0116] The second hardware structure,

[0117] In the embodiment provided in the present application, the first wireless headset includes multiple antenna units, and different antenna units have different radiation directions; the first wireless headset also includes a second communication circuit, and the second communication circuit may include multiple RF ports; the second communication circuit is connected to the multiple antenna units through the multiple RF ports; the multiple RF ports correspond one-to-one to the multiple antenna units.

[0118] Here, the first wireless headset has two antenna units as an example for explanation. Figure 5 As shown in the third schematic diagram of the hardware structure of a first wireless headset, the first wireless headset may include two antenna units: an antenna unit 51 and an antenna unit 52; wherein a radiation direction of the antenna unit 51 and a radiation direction of the antenna unit 52 form a preset angle. The preset angle may be an angle obtained by experimental calculation in advance.

[0119] The first wireless headset further includes a second communication circuit 53. The second communication circuit 53 has two radio frequency ports, and the second communication circuit 53 is connected to the antenna unit 51 through the first radio frequency port and is connected to the antenna unit 52 through the second radio frequency port.

[0120] In one possible implementation, reference Figure 6 The hardware structure of a first wireless headset is shown in FIG. Figure 4 , each antenna unit may include a filter circuit 61, a matching circuit 62 and an antenna 63;

[0121] The first end of the filter circuit 61 is connected to the first end of the matching circuit 62 , the second end of the matching circuit 62 is connected to the antenna 63 ; and the second end of the filter circuit 61 is connected to a radio frequency port of the second communication circuit 53 .

[0122] Here, the functions and specific structures of the matching circuit and the filtering circuit are similar to those described above and will not be repeated here.

[0123] It can be seen that the second communication circuit in the embodiment of the present application has multiple RF ports, and each RF port can be connected to an antenna unit, so that the second communication circuit can simultaneously receive multiple signals to be processed and simultaneously process multiple signals to be processed.

[0124] Based on the second hardware structure, in the embodiment provided in the present application, step 2101' controls at least two antenna units among the multiple antenna units to receive the same transmission signal in the radiation directions respectively corresponding to the at least two antenna units to obtain at least two signals to be processed, which can be implemented in the following manner:

[0125] The first wireless headset controls multiple antenna units, and simultaneously receives the same transmission signal in radiation directions corresponding to at least two antenna units, thereby obtaining at least two signals to be processed.

[0126] It can be understood that in the embodiments provided in the present application, the first wireless headset can control the first antenna unit to concentrate at least two antenna units, and simultaneously receive the same transmission signal transmitted by the second wireless headset; and / or the first wireless headset can control the second antenna unit to concentrate at least two antenna units, and simultaneously receive the same transmission signal transmitted by the terminal device, to obtain at least two signals to be processed.

[0127] In a possible implementation, step 2102′ determines the target processing signal based on at least two signals to be processed, which can be implemented by the following steps:

[0128] Step a: The first wireless headset determines a signal to be processed whose signal quality is greater than a preset threshold from at least two signals to be processed, and obtains a target processed signal.

[0129] In the embodiment provided in the present application, the first wireless headset can detect a signal to be processed with a higher signal quality among at least two signals to be processed, and demodulate the signal as target processing information.

[0130] In addition, in the embodiment provided in the present application, when the quality of the communication link between the first wireless headset and is relatively poor, the first wireless headset can automatically detect the signal strength of the paths corresponding to at least two antenna units and intelligently switch the antenna path that is more conducive to communication.

[0131] It is understandable that, due to the different radiation directions of the antenna units, when the signal to be processed received by one antenna unit in its radiation direction is drowned by noise and becomes invalid, the signal quality of the signal to be processed received by another antenna unit in its radiation direction is relatively high. Therefore, by selecting the signal to be processed with relatively high signal quality from at least two signals to be processed as the target processing signal, and demodulating the target processing signal, the target data carried in the target processing signal can be accurately restored, thereby reducing the packet loss rate during data transmission.

[0132] In addition, in the embodiments provided in the present application, when the quality of the communication link between the first wireless headset and the data transmitting end (the second wireless headset and / or the terminal device) is relatively poor, the processor can automatically detect the signal strength of the two paths and intelligently switch the antenna path that is more conducive to communication to improve the RF connection stability and anti-interference capability of the first wireless headset.

[0133] In another possible implementation, determining the target processing signal based on the multiple signals to be processed in step 2101′ can also be implemented by the following steps:

[0134] Step a', the first wireless headset determines weight values ​​corresponding to at least two signals to be processed respectively; the weight values ​​are used to characterize the signal quality of the signals to be processed;

[0135] Step b': based on at least two signals to be processed and the weight values ​​respectively corresponding to the at least two signals to be processed, weighted sum processing is performed on the at least two signals to be processed to obtain a target processed signal.

[0136] In the embodiments provided in the present application, maximum ratio combining diversity can be introduced to achieve more effective receiving diversity. Specifically, the specific operation of the maximum ratio combining diversity method is to weight and process multiple signals to be processed.

[0137] Specifically, the first wireless headset first needs to determine a weight value corresponding to each signal to be processed.

[0138] In a possible implementation, the first wireless headset can determine a weight value corresponding to each of the at least two signals to be processed based on the signal voltage and noise power of each of the at least two signals to be processed. Here, the weight value of the signal to be processed is determined by the ratio of the signal voltage to the noise power of the signal to be processed.

[0139] In another possible implementation, the first wireless headset may also set a weight value corresponding to the signal to be processed based on preset parameters. The weight value of each signal to be processed may be set to the same value. This is because, in practical applications, when at least two signals to be processed are combined according to the maximum ratio combining diversity method, it is necessary to calculate the weight value corresponding to each signal to be processed, and the weight value varies with the signal quality, so it is not very easy to calculate the weight value. Therefore, the equal gain combining method may be used to combine the at least two signals to be processed.

[0140] In the embodiments provided in the present application, the weight value corresponding to the signal to be processed can be set according to a preset parameter, and the weight value corresponding to each signal to be processed is the preset parameter. Furthermore, based on at least two pieces of information to be processed and the weight values ​​corresponding to at least two signals to be processed, at least two signals to be processed are weighted and processed to obtain a target processed signal.

[0141] In the embodiment provided in the present application, after weighted sum processing is performed on the at least two signals to be processed, the signal-to-noise ratio of the target processed signal obtained is equal to the sum of the signal-to-noise ratios of the at least two signals to be processed.

[0142] In one embodiment of the present application, when the signal quality of at least two signals to be processed is very poor, so that none of the signals to be processed can be demodulated by the receiver alone, it is still possible to merge a demodulated signal that achieves the minimum signal-to-noise ratio of the receiver using the above scheme, thereby improving the receiving sensitivity of the first wireless headset.

[0143] In the embodiment provided in the present application, step b' weights and processes at least two signals to be processed based on at least two pieces of information to be processed and weight values ​​corresponding to at least two signals to be processed to obtain a target processed signal, which can be achieved in the following manner:

[0144] Adjusting the phases of at least two signals to be processed so that the at least two signals to be processed have the same phase after the phase adjustment;

[0145] Based on the at least two signals to be processed after phase adjustment and the weight values ​​respectively corresponding to the at least two signals to be processed, the at least two signals to be processed after phase adjustment are weighted and processed to obtain a target processed signal.

[0146] In practical applications, when performing weighted sum processing on at least two signals to be processed, that is, when combining at least two signals to be processed, it is required that at least two signals to be processed have the same phase.

[0147] Based on this, in the embodiment provided in the present application, after obtaining at least two signals to be processed, the first wireless headset can adjust the phase of each signal to be processed so that the phase of each signal to be processed is the same. Here, multiple phase adjustment circuits can be integrated in the first wireless headset, and the multiple phase adjustment circuits correspond to the antenna units one by one. In this way, after receiving at least two signals to be processed through at least two antenna units, the phases of the signals to be processed are adjusted through their corresponding phase adjustment circuits to obtain at least two signals to be processed after phase adjustment. Furthermore, the at least two signals to be processed after phase adjustment are weighted and processed to obtain the target processed signal.

[0148] It should be noted that when performing weighted sum processing on at least two signals to be processed after phase modulation, the weight value corresponding to each signal to be processed before phase modulation can continue to be used for weighted sum processing. Optionally, the weight value can be determined based on preset parameters as described in the above embodiment, that is, the weight value of each signal to be processed is the same value.

[0149] In the above-mentioned second hardware structure, the second communication circuit may include multiple RF ports and multiple antenna units. Therefore, the embodiment of the present application can perform beamforming through multiple antenna units to improve communication quality.

[0150] In the embodiments provided in the present application, the first wireless headset may identify the first location where the second wireless headset is currently located, and / or the second location where the terminal device is currently located;

[0151] Based on the first orientation, determine configuration information of each antenna unit in the first antenna unit set so that the radiation direction of the antenna array composed of multiple antenna units in the first antenna unit set matches the first orientation;

[0152] Based on the second orientation, determine configuration information of each antenna unit in the second antenna unit set so that the radiation direction of the antenna array composed of multiple antenna units in the second antenna unit set matches the second orientation;

[0153] Based on the configuration information of the first antenna unit set, data is transmitted with the second wireless headset, and / or based on the configuration information of the second antenna unit set, data is transmitted with the terminal device.

[0154] In the embodiments provided in the present application, when the relative positions of the first wireless headset and the second wireless headset or the terminal device change, resulting in poor radiation capability of the antenna unit in the direction of the second wireless headset or the terminal device, thereby causing the quality of the communication link to deteriorate, in order to enhance the radiation direction of the antenna to track the second wireless headset and / or the terminal device, a plurality of antenna units can be used to form an antenna array, and beamforming can be achieved through the antenna array.

[0155] Exemplary, reference Figure 7An exemplary antenna array composition schematic diagram is shown. When the first wireless headset includes two antenna units, the antennas in the two antenna units can be arranged adjacent to each other.

[0156] Specifically, the first wireless headset can adjust the configuration information of multiple antenna units in the antenna array, control the amplitude and phase of the electromagnetic waves emitted by the antenna so that the transmit / receive signals of the antenna array in a specific direction are coherently superimposed, while the signals in other directions cancel each other out, thereby aligning the main lobe of the radiation pattern of the antenna array composed of the antenna units toward the second wireless headset and / or terminal device.

[0157] Here, the configuration information may include antenna unit transmit power and phase.

[0158] In the embodiment provided in the present application, the first wireless headset can control multiple antenna units to transmit detection signals in a preset order to determine the location of the second wireless headset and / or the terminal device, and then adjust the configuration information of the multiple antenna units according to the location.

[0159] For example, in Figure 7 In the antenna array structure shown, when the target azimuth is 90°, the processor can control the two antenna units to excite with the same phase and amplitude to form the radiation pattern shown in Figure 8(a). In Figure 8(a), the main beam of the pattern points to the 90° direction.

[0160] When the target azimuth changes to 105°, the processor can adjust the transmit power and phase of each antenna element in the antenna array to form the radiation pattern shown in Figure 8(b). In Figure 8(a), the main beam of the pattern points to the 105° direction. Further, when the target azimuth changes to 120°, the processor can continue to adjust the transmit power and phase of each antenna element in the antenna array to form the radiation pattern shown in Figure 8(c). In Figure 8(c), the main beam of the pattern points to the 120° direction.

[0161] In this way, the first wireless headset can obtain better communication quality between the two headsets, or between the first wireless headset and the terminal device by continuously changing the main beam pointing direction of the directional diagram, thereby improving the receiving sensitivity of the first wireless headset.

[0162] Optionally, in the above embodiment, the multiple antenna units can be specifically two antenna units. In this way, the first wireless headset can use the two antenna units to perform data transmission with the second wireless headset, and can also use the two antenna units to perform data transmission with the terminal device. The first wireless headset can also use one of the two antenna units to perform data transmission with the second wireless headset, and use the other antenna unit to perform data transmission with the terminal device. In this way, the communication performance of the wireless headset, such as data transceiving capability and anti-interference capability, is improved in the compatible ear-to-ear communication (communication between the first wireless headset and the second wireless headset) and terminal communication (communication between at least one headset in a pair of headsets and the terminal device) modes.
