Fig. 4 is a schematic implementation flowchart of a bluetooth communication method according to an embodiment of the present application, and as shown in fig. 4, the method may include the following steps 401 to 403:

step 401, a processor determines a first frequency hopping frequency point and a second frequency hopping frequency point; the distance between the first frequency hopping frequency point and the second frequency hopping frequency point is greater than or equal to a safety distance;

wherein the safe distance is set to enable the adjacent channel interference index of the first Bluetooth device and/or the adjacent channel interference index of the second Bluetooth device to respectively meet corresponding preset standards.

Step 402, the processor controls the first radio frequency processing unit to modulate first data onto the first frequency hopping frequency point so as to send the first data to the first bluetooth device; and

and 403, the processor controls the second radio frequency processing unit to modulate second data onto the second frequency hopping frequency point so as to send the second data to the second bluetooth device.

In the embodiment of the application, data are modulated out through two channels in a manner similar to FDD, rather than a TDD data transmission manner, and the distance between a first frequency hopping frequency point and a second frequency hopping frequency point is greater than or equal to a safety distance; therefore, the data transmission rate of the Bluetooth communication is improved through the first radio frequency processing unit and the second radio frequency processing unit, and meanwhile, the adjacent channel interference of two paths of transmitting signals can be reduced, so that the signal receiving quality of a receiving party (namely, the first Bluetooth device and the second Bluetooth device) is improved, and the receiving party can correctly decode received signals, so that the overall efficiency of data transmission is improved.

As shown in fig. 5, the electronic device 101 includes a processor 501, a first baseband processing unit 502, a first radio frequency processing unit 503, a second baseband processing unit 504, and a second radio frequency processing unit 505; after the processor 501 selects the first frequency hopping frequency point and the second frequency hopping frequency point, the processor 501 controls the first radio frequency processing unit 503 to modulate the first data generated by the first baseband processing unit 502 onto the first frequency hopping frequency point, so that the first radio frequency signal generated by modulation is sent to the first bluetooth device 102 through the antenna; moreover, the processor 501 controls the first rf processing unit 503 and controls the second rf processing unit 505 to modulate the second data generated by the second baseband processing unit 504 onto the second frequency hopping point, so as to send the second rf signal generated by modulation to the second bluetooth device 103 through the antenna; the distance between the first frequency hopping frequency point and the second frequency hopping frequency point is greater than or equal to the safety distance, so that the mutual interference of the first radio frequency signal and the second radio frequency signal in the transmission process or the receiving process can be reduced.

Further alternative embodiments of the above steps and related terms are described below.

In step 401, the processor determines a first frequency hopping frequency point and a second frequency hopping frequency point; and the distance between the first frequency hopping frequency point and the second frequency hopping frequency point is greater than or equal to a safe distance.

In some embodiments, the developer may determine the safety distance based on the indicator requirement of the first bluetooth device and the second bluetooth device for adjacent channel interference, so as to pre-configure the safety distance, thereby facilitating the processor to directly call the pre-configured safety distance to search for the second frequency hopping frequency point.

The method by which the processor determines the first frequency hopping point and the second frequency hopping point may be various. For example, in some embodiments, the processor may select a first hopping frequency point from a fourth bluetooth frequency point list and a second hopping frequency point from a fifth bluetooth frequency point list, as shown in fig. 6, where the frequency points in the fourth bluetooth frequency point list and the frequency points in the fifth bluetooth frequency point list are completely different, the maximum frequency point in the fourth bluetooth frequency point list is smaller than the minimum frequency point in the fifth bluetooth frequency point list, and the distance between the maximum frequency point and the minimum frequency point is greater than the safety distance H.

However, the method for selecting the frequency hopping point actually reduces the selection range of the frequency hopping point, and if all the frequency points in the fourth bluetooth frequency point list are interfered, the first data cannot be successfully transmitted to the first bluetooth device, so that the use experience of a user is affected.

Based on this, in order to expand the selection range of the hopping frequency points while ensuring that the distance between two selected hopping frequency points is greater than or equal to the safety distance, two solutions of embodiment 1 and embodiment 2 are provided as follows. Wherein the content of the first and second substances,

in embodiment 1, the processor may select the frequency hopping points by: selecting the first frequency hopping frequency point from a first Bluetooth frequency point list; acquiring the safety distance; searching the second frequency hopping frequency point from the first Bluetooth frequency point list based on the safety distance and the first frequency hopping frequency point; so, because the selection of first frequency hopping frequency point and second frequency hopping frequency point shares a bluetooth frequency point list, rather than segmenting this bluetooth frequency point list into two lists that the frequency point is complete different, consequently greatly increased the selection range at first frequency hopping frequency point and second frequency hopping frequency point to can avoid the interference more effectively, guarantee data transmission quality.

Even if the first frequency hopping frequency point and the second frequency hopping frequency point are selected not to share one Bluetooth frequency point list, the Bluetooth frequency point lists respectively used by the first frequency hopping frequency point and the second frequency hopping frequency point also share the same frequency point. Specifically, in embodiment 2, the processor may also select the frequency hopping points as follows: selecting the first frequency hopping frequency point from a second Bluetooth frequency point list; acquiring the safety distance; searching the second frequency hopping frequency point from a third Bluetooth frequency point list based on the safety distance and the first frequency hopping frequency point; the third Bluetooth frequency point list and the second Bluetooth frequency point list have a common frequency point, but the frequency points in the two lists are not completely different; therefore, the selection ranges of the first frequency hopping frequency point and the second frequency hopping frequency point are increased, so that interference can be effectively avoided, and the data transmission quality is guaranteed.

It is understood that the bluetooth system operates in the unlicensed ISM band, and the 2.4GHz ISM band is a band open to all radio systems, and not only does the bluetooth system operate in this band, but most wireless local area networks, some cordless telephones, and some military or civil communications use this band, and the radio waves of microwave ovens and high pressure sodium lamps are within this frequency range, so the ISM spectrum has become crowded and noisy, and any system using the ISM band encounters interference. The bluetooth system implements frequency spreading by a frequency hopping technique, so that signals transmitted by the system operate in a wider frequency band, and are not easily affected by electromagnetic noise and other interference signals.

The working frequency band of the Bluetooth system is 2400 MHz-2483.5 MHz, different countries use different frequencies, including 79 frequency point and 23 frequency point (only slightly different in frequency hopping frequency definition). Therefore, there is no limitation on whether the first bluetooth frequency point list includes 79 frequency points or 23 frequency points.

Optionally, the first bluetooth frequency point list may include 79 frequency points, the frequency of the 79 frequency points is 2402MHz to 2480MHz in sequence, and the frequency interval between two adjacent frequency points is1 MHz. The processor selects 1600 times the first hopping frequency point and correspondingly 1600 times the second hopping frequency point in the bluetooth frequency point list every second, namely the hopping rate is 1600 times/second. Or, the first bluetooth frequency point list may also include some of the above 79 frequency points, which is not limited to this, and the frequency points in the first bluetooth frequency point list may be configured according to actual situations. Or, in an initial state, the first bluetooth frequency point list includes 79 frequency points, and along with the progress of the communication process, the processor may also adaptively update the frequency points in the first bluetooth frequency point list based on the degree of interference of each frequency point.

The frequency points in the second bluetooth frequency point list and the third bluetooth frequency point list may be completely the same or partially the same. Optionally, the frequency points in the two lists are all selected from the 79 frequency points.

It should be noted that, in the above embodiment 1, the processor searches the second frequency hopping frequency point from the first bluetooth frequency point list based on the safe distance and the first frequency hopping frequency point, and in the above embodiment 2, the processor searches the second frequency hopping frequency point from the third bluetooth frequency point list based on the safe distance and the first frequency hopping frequency point, and the adopted algorithms are the same. In some embodiments, taking the unit of the safe distance as the difference value of the frequency point numbers as an example, the processor may search for the second frequency hopping frequency point by:

taking the sum of the first frequency hopping frequency point and the safety distance as a first reference value, searching frequency points which are greater than or equal to the first reference value from the Bluetooth frequency point list, and determining any frequency point which is greater than or equal to the first reference value as the second frequency hopping frequency point; the Bluetooth frequency point list is the first Bluetooth frequency point list or the third Bluetooth frequency point list; determining the minimum frequency point in the Bluetooth frequency point list as the second frequency hopping frequency point based on determining that no frequency point greater than or equal to the first reference value is found; therefore, when the frequency point which is larger than or equal to the first reference value is not found, the minimum frequency point in the Bluetooth frequency point list is directly used as the second frequency hopping frequency point, so that the requirement on the safety distance can be met, and the frequency point selection efficiency can be improved.

In some embodiments, the frequency points in the first bluetooth frequency point list, the second bluetooth frequency point list and the third bluetooth frequency point list are arranged according to a specific rule, such as from small to large or from large to small. Therefore, when the processor does not find a frequency point which is greater than or equal to the first reference value (the first frequency hopping frequency point + the safety distance) from the Bluetooth frequency point list, the first frequency hopping frequency point is in a high position, and the distance between the minimum frequency point and the first frequency hopping frequency point is far greater than the safety distance. As shown in fig. 7, the frequency points in the list are arranged in order from small to large, and assuming that the safety distance is 10 when the frequency points 1 to 79 are included, and the first hopping frequency point is 70, the first reference value is 80, and obviously, the distance between the minimum frequency point 1 and the frequency point 70 is far greater than the safety distance 10.

However, there may be a case where the minimum frequency point is interfered, and therefore, in other embodiments, the processor may also use a difference between the first hopping frequency point and the safe distance as a second reference value when it is determined that no frequency point greater than or equal to the first reference value is found, search a frequency point smaller than the second reference value from the bluetooth frequency point list, and determine any frequency point smaller than the second reference value as the second hopping frequency point; therefore, the flexibility of frequency point selection can be increased, and the Bluetooth communication performance is improved.

Certainly, the processor may also use the absolute value of the difference between the first frequency hopping frequency point and the safe distance as a reference value to search for the second frequency hopping frequency point, and still take the unit of the safe distance as the difference of the frequency point number as an example, in some embodiments, the processor may also search for the second frequency hopping frequency point as follows: taking the difference (here, an absolute value) between the first frequency hopping frequency point and the safety distance as a second reference value, searching a frequency point smaller than or equal to the second reference value from the bluetooth frequency point list, and determining any frequency point smaller than or equal to the second reference value as the second frequency hopping frequency point; the Bluetooth frequency point list is the first Bluetooth frequency point list or the third Bluetooth frequency point list; determining the maximum frequency point in the Bluetooth frequency point list as the second frequency hopping frequency point based on determining that no frequency point smaller than or equal to the second reference value is found; alternatively, the first and second electrodes may be,

and based on the fact that the frequency point smaller than or equal to the second reference value is not found, taking the sum of the first frequency hopping frequency point and the safety distance as a first reference value, searching the frequency point larger than the first reference value from the Bluetooth frequency point list, and determining any frequency point larger than the first reference value as the second frequency hopping frequency point.

In step 402 and step 403, the processor controls the first rf processing unit to modulate the first data onto the first frequency hopping point, so as to send the first data to the first bluetooth device; and controlling a second radio frequency processing unit to modulate second data onto the second frequency hopping frequency point so as to send the second data to second Bluetooth equipment.

Optionally, the processor controls the first radio frequency processing unit and the second radio frequency processing unit to perform frequency hopping modulation on the corresponding data at the same time. Even if the two radio frequency processing units do not perform frequency hopping modulation on corresponding data at the same time, the time difference of the modulation time is smaller than the modulation interval of the first data and the second data in the original TDD mode.

The selection of the second frequency hopping point in the above embodiments is implemented by the processor 501, and in other embodiments, the selection of the second frequency hopping point may also be implemented by the second baseband processing unit. Accordingly, an embodiment of the present application further provides a bluetooth communication method, and fig. 8 is a schematic flow chart of another implementation of the bluetooth communication method provided in the embodiment of the present application, as shown in fig. 8, the method may include the following steps 801 to 803:

step 801, the second baseband processing unit 504 determines a first frequency hopping point selected by the first baseband processing unit 502; the first frequency hopping frequency point is used for the first radio frequency processing unit 503 to modulate the first data to send to the first bluetooth device 102;

step 802, the second baseband processing unit 504 determines a second frequency hopping point based on the first frequency hopping point and the safety distance; the distance between the first frequency hopping frequency point and the second frequency hopping frequency point is greater than the safety distance;

in step 803, the second baseband processing unit 504 modulates the second data onto the second frequency hopping point through the second rf processing unit 505, so as to send the second data to the second bluetooth device 103.

It should be noted that, for step 802, the second baseband processing unit 504 determines the second frequency hopping point based on the first frequency hopping point and the safety distance, and the implementation steps thereof are consistent with the implementation steps described in the foregoing embodiments, and therefore, details are not described here.

For the selection of the first frequency hopping point, the selection may be performed based on a frequency hopping selection algorithm defined by a bluetooth standard protocol, which is not described herein again.

In the embodiment of the present application, the first data and the second data may be various types of data, and the data types thereof are related to usage scenarios of the bluetooth communication method. In some embodiments, the type of the first data and the type of the second data are audio data, the first bluetooth device is a first audio playing device, and the second bluetooth device is a second audio playing device. For example, the first audio playing device and the second audio playing device are bluetooth headsets; therefore, the correct receiving of data can not be influenced at the Bluetooth earphone end while high-definition music can be transmitted by the electronic equipment, and therefore a user can smoothly enjoy lossless high-definition music by using the Bluetooth earphone.

Bluetooth has a great application in listening to audio, and bluetooth headsets are gradually becoming standard accessories for mobile phones. However, the rates in the bluetooth standard protocol are BR 1M, EDR 2M/3M, BLE 1M and 2M, etc., which are still relatively deficient for transmitting high-definition music. Mainstream manufacturers are trying to increase packet rate, such as bandwidth and modulation coding capability. By the methods, the packet rate can be improved well, so that high-definition music is served. However, the bandwidth capability of bluetooth is still lacking for carrying high definition music and lossless high definition music.

As shown in fig. 2, a handset is Connected to 2 bluetooth headsets, and an audio connection for connecting a synchronous Stream (CIS 1) is established with the headset 1 and an audio connection for connecting the CIS2 with the headset 2, respectively. Only monaural audio data is transmitted over 1 audio connection. As shown in fig. 9, the CIS1 and CIS2 are transported in TDD mode, i.e., the CIS1 is transported first, and then the CIS2 is transported.

In other embodiments, the transmission of the CIS1 and the CIS2 is realized in an FDD mode, and the CIS1 and the CIS2 transmit simultaneously but at different frequency points respectively.

As shown in fig. 10, the CIS1 and the CIS2 are completely aligned in time, that is, the first rf processing unit and the second rf processing unit are completely aligned in time when modulating data, but they use different frequency points. CIS2 was F2 when CIS1 was F1; CIS1 was F3, CIS2 was F4; wherein F1 and F2 are staggered and maintain a sufficient safety distance to avoid the recipient of CIS2 receiving an unauthorized signal due to F1 interfering with F2. Or F2 interferes with F1, causing the receiver of CIS1 to receive no-pair signals. The safe distances of F1 and F2 may be determined based on the received interference rejection capability, i.e., adjacent channel interference indicator (ACI).

To solve the frequency hopping problem of FDD. As described above, the frequency points of CIS1 and CIS2 must be separated by a certain distance, and there are the following methods:

the CIS1 uses a fourth Bluetooth frequency point list of frequency hopping points, the CIS2 uses a fifth Bluetooth frequency point list of frequency hopping points, and the frequency points of the fourth Bluetooth frequency point list (map1) and the fifth Bluetooth frequency point list (map2) are completely different. The maximum frequency point of the fourth Bluetooth frequency point list is smaller than the minimum frequency point of the fifth Bluetooth frequency point list, and the distance between the maximum frequency point and the minimum frequency point is larger than the safety distance H.

The CIS1 and the CIS2 share a list (map), frequency points are arranged into an array from small to large, firstly, the CIS1 obtains a frequency point F1 according to a certain method (such as a frequency hopping selection algorithm defined by a Bluetooth standard protocol), the CIS2 adds a threshold H on the basis of the frequency point F1, then, the first frequency point larger than F1+ H is searched, and if the frequency point cannot be found, the smallest frequency point is used. This method is merely an example. In the embodiment of the application, two channels of CIS of FDD share one frequency point hopping list.

In the scheme 2, two CIS share one frequency point hopping list, so that the frequency point hopping list is more efficient. The scheme 1 divides the frequency point list into 2 groups, actually reduces the frequency point selection range, if the fourth bluetooth frequency point list (map1) is interfered, the CIS1 can not transmit at all, and if the fourth bluetooth frequency point list and the fifth bluetooth frequency point list (map1 and map2), the CIS1 and the CIS2 share one list map, and the large selection range is increased. Or the fourth bluetooth frequency point list and the fifth bluetooth frequency point list have most frequency points which are the same, or the fourth bluetooth frequency point list and the fifth bluetooth frequency point list have most frequency points which are the same.

In the embodiment of the application, the number of the frequency points of each path of CIS is increased, so that interference can be avoided more effectively, and transmission quality is guaranteed.

In the embodiment of the application, 2 bluetooth baseband devices or transceivers are configured in the mobile phone, and the audio data are respectively sent to 2 earphones in an FDD manner, so that the bluetooth bandwidth can be increased to twice of the original bandwidth to bear the high-speed audio data. But at the same time, the frequency points of the two branches are required to be separated by enough safety distance, and the safety distance depends on the adjacent channel interference index of the receiving party. The frequency point lists of the two CIS channels are the same frequency point list or most frequency points of the two CIS channels are the same, and different frequency points are used at the same moment through the improvement of a frequency hopping method, so that the problems of few frequency points and poor performance under the interference condition are solved.

In the embodiment of the present application, there are many frequency hopping methods after using the same frequency point list. Not all are enumerated here.
