Description

Control method for operation mode of wireless device, wireless device and medium

Technical Field

The present invention relates to the field of wireless communication technology, and more particularly, to a control method for an operation mode of a wireless device, and a medium.

Background

As wireless communication technology evolves and user demands increase, wiFi and bluetooth coexist in the same wireless device more and more commonly. In a WiFi and bluetooth co-existing device, wiFi and bluetooth may operate in both FDD (Frequency Division Duplex ) or TDD (Timer Division Duplex, time division duplex), where FDD is a full duplex mode, in which WiFi and bluetooth may operate simultaneously using different channels without back-off, so that they can support higher data rates, while TDD corresponds to half duplex mode, and the same time slot only allows WiFi or bluetooth to operate, so that under the same conditions, they support about half the data rate of FDD mode.

In existing WiFi and bluetooth co-existing wireless devices, the FDD/TDD mode of operation is typically preset in association with the application traffic scenario and once set does not support dynamic changes. Furthermore, particularly when WiFi and bluetooth operate in the same frequency band (i.e., 2.4GHz band) and share the same antenna, the mode of operation of the wireless device is typically set to TDD to avoid possible mutual interference. Therefore, the existing FDD/TDD mode setting manner is not flexible enough, on one hand, the data rate may not be improved due to the fixed TDD mode in a specific scenario, and on the other hand, when the FDD mode with higher data rate is fixed in some scenarios, once the inter-channel interference occurs, the corresponding adjustment measures cannot be timely identified and taken, so that the error rate may be increased due to the inter-channel interference, and the communication performance is reduced.

In this application, the character "/" generally indicates that the associated object is an or relationship.

The application provides a wireless device. Fig. 1 shows a schematic diagram of the partial composition of a wireless device according to an embodiment of the present application. As shown in fig. 1, the wireless device 100 includes a WiFi module 101, a bluetooth module 102, and a control part 103 for controlling an operation mode of the wireless device 100, where the operation mode includes a TDD mode and an FDD mode, and in the FDD mode, the WiFi module 101 and the bluetooth module 102 may operate in a frequency division duplex mode, that is, the WiFi module 101 and the bluetooth module 102 may simultaneously perform data transmission with each other without avoiding each other using a pre-planned channel and/or a channel set that is not expected to generate mutual interference, in this operation mode, by way of example only, when the WiFi module 101 sends a WiFi data transmission request to the control part 103, or when the bluetooth module 102 sends a bluetooth data transmission request to the control part 103, the control part 103 may immediately respond to the data transmission requests of the WiFi module 101 and the bluetooth module 102, so that the WiFi module 101 and the bluetooth module 102 may simultaneously perform data transmission in a manner independent of each other, and thus, both the WiFi module 101 and the bluetooth module 102 may achieve a higher data rate. Compared with FDD full duplex, TDD mode is equivalent to half duplex, and only one of WiFi module 101 and bluetooth module 102 is allowed to work in the same time slot, so in TDD mode, control unit 103 needs to respond to data transmission request of WiFi module 101 and bluetooth module 102 in a time-sharing manner according to a preset time slot division mode, so that WiFi module 101 and bluetooth module 102 avoid data transmission in the same time slot at the same time, and therefore, taking time slot division 1:1 as an example, the data rate that WiFi module 101 and bluetooth module 102 can reach is about half of that in FDD mode.

In some embodiments, the wireless device 100 may further include a WiFi antenna (not shown) for transmitting and receiving WiFi signals, and a bluetooth antenna (not shown) for transmitting and receiving bluetooth signals, where the WiFi antenna and the bluetooth antenna may be separate antennas or may be a common antenna. It should be noted that, whether the WiFi module 101 and the bluetooth module 102 use separate antennas or share the same antenna, if they operate independently in the same frequency band, for example, the WiFi module 101 and the bluetooth module 102 operate in the 2.4GHz frequency band, then mutual interference may occur due to insufficient antenna isolation between the operating channels. It is particularly noted that even for pre-planned channels and/or channel sets for FDD mode, interference between channels may still occur during actual operation.

For the above reasons, in the embodiment according to the present application, the control section 103 is further configured to control the operation mode of the wireless device 100, specifically, the steps of the control method for the operation mode of the wireless device according to the embodiments of the present application may be performed, and the control method for the operation mode of the wireless device according to the embodiment of the present application will be described in detail below with reference to fig. 2.

As shown in fig. 2, in step 201, it may be detected whether the WiFi module is connected to the AP at intervals of a first time, and in the case that the WiFi module is connected to the AP and the WiFi module and the bluetooth module are both independently operated in the same frequency band, the

following steps

202 and 203 are performed.

In general, when the detection result indicates that the WiFi module is connected to the AP, it can determine the frequency band used by the WiFi module, for example, the 5GHz frequency band or the 2.4GHz frequency band, and when the frequency band used by the WiFi module is the 2.4GHz frequency band and the bluetooth module is transmitting bluetooth data at this time, then both the WiFi module and the bluetooth module can be considered to operate independently in the same frequency band.

In some embodiments, the first time interval may be set to 1 second or 0.5 second, for example. In other embodiments, the simulation or test may be performed in combination with factors such as the processing capability of the software and hardware of the wireless device, and the first time interval is set to an appropriate value according to the result of the simulation or test, which is not limited in this application. Through reasonable setting of the first time interval, whether the AP access state of the WiFi module changes, whether the WiFi module and the Bluetooth module independently work in the same frequency band or not is facilitated, and the change of parameters used for setting the working mode in the subsequent steps timely senses and executes corresponding adjustment, and meanwhile AP access detection and other judging processes can be prevented from being too frequent, namely, the software and hardware burden of the wireless device is not increased too much.

Then, in step 202, a first received signal strength indication rssi value of a channel being used by the WiFi module may be further obtained. rssi (Received Signal Strength Indication ) is used to indicate the strength of the WiFi signal, which is the total power of the signal received by the receiver in the WiFi module, measured in dBm. During WiFi data transmission, under the condition that the transmitting power of a transmitter is fixed, the rssi value at a receiver can be changed under the influence of various interferences, including mutual interference caused by insufficient isolation between a channel used by a Bluetooth module and a channel currently used by the WiFi module. Thus, the rssi value of the WiFi module may be used to characterize the disturbed condition of the channel being used. In some embodiments, the rssi value measured by the WiFi module receiver may be directly used as the first rssi value, for example, the first rssi value may be obtained by reading a memory address that fixedly stores the rssi value, and in other embodiments, the first rssi value may also be obtained by other manners, which is not limited in this application.

Next, in step 203, an operation mode of the wireless device may be caused to be in a corresponding operation mode based on the determination of the rssi value, wherein the operation mode is caused to be in a TDD mode if the rssi value is less than an rssi threshold of a corresponding channel. In some embodiments, the rssi threshold values for each channel that the WiFi module may use when operating may be pre-stored in the memory space of the wireless device to be quickly read if needed and used to compare with the acquired rssi values for the channel currently being used by the WiFi module. When the acquired rssi value is smaller than the pre-stored rssi threshold value of the corresponding channel, the current channel used by the WiFi module can be considered to receive stronger interference, in this case, in order to ensure the communication quality of the system, when the current working mode of the wireless device is the FDD mode, the working mode may be switched to the TDD mode, or when the current working mode is the TDD mode, the working mode is kept in the TDD mode.

Through the steps 201-203, the AP connection status of the WiFi module, whether the WiFi module and the bluetooth module are all independently operated in the same frequency band, and whether the WiFi module is interfered with the status can be monitored, wherein the si value of the WiFi communication which is easy to obtain is compared with the si threshold value of the corresponding channel stored in advance, so that the inter-channel interference status of the WiFi module and the bluetooth module can be conveniently and accurately identified, and therefore, the working mode of the wireless device can be switched to or kept in the TDD mode only when the WiFi module is connected with the AP and the channel interfered with the status currently being used by the WiFi module exceeds the threshold value of the corresponding channel, on the one hand, the inter-channel interference can be timely and accurately identified, and the influence of the interference can be avoided through the switching of the working mode, and the communication quality of the WiFi module and the bluetooth module is ensured; on the other hand, the operation mode is switched to the TDD mode only when necessary, so that the WiFi module and the Bluetooth module can operate in the FDD mode with higher data rate as much as possible, and the overall data transmission efficiency of the wireless device is improved.

As shown in fig. 3, in step 301, it may be determined whether the WiFi module is connected to the access point AP, in some cases, for example, when there is no data transmission for a long time, the WiFi module may temporarily enter a sleep state and disconnect the AP, where even if the bluetooth module is transmitting data, it will not interfere with bluetooth communication, so in case that the determination result in step 301 is "no", step 307 may be entered, that is, the operation mode of the wireless device is set to FDD mode, and it may be understood that if the current operation mode is TDD mode, the mode is switched from TDD mode to FDD mode, and if the current operation mode is FDD mode, mode switching is not required. In the FDD mode, the wireless device immediately responds to the data transmission request of the WiFi module and the data transmission request of the bluetooth module, so that the wireless device has higher data transmission efficiency.

If the determination result in step 301 is yes, that is, if the WiFi module is connected to the AP, step 302 is entered, and in step 302, it is determined whether the WiFi module and the bluetooth module are both operating independently in the same frequency band. As described above, in some embodiments, the used frequency band may be obtained through the AP connection of the WiFi module, so as to determine whether the WiFi module and the bluetooth module are using the same frequency band, and in other embodiments, for example, the WiFi module of the wireless device fixedly works in the 2.4GHz frequency band or the 5GHz frequency band, then the working frequency band of the WiFi module may also be directly obtained. When the determination result in step 302 is "no", the WiFi module and the bluetooth module may use the FDD mode with higher data rate to perform full duplex communication without generating inter-channel interference. Therefore, in the case that the determination result of step 302 is "no", step 307 may also be entered, that is, the operation mode of the wireless device is set to the FDD mode.

If the determination result in step 302 is yes, step 303 is entered to further obtain the first received signal strength indicator rssi value of the channel being used by the WiFi module, which is similar to step 203 in fig. 2 and is not repeated herein.

Next, in step 304, it is determined whether the first rssi value is smaller than the rssi threshold of the corresponding channel, and if the determination result is "no", it indicates that the channel used by the current WiFi module is not subjected to inter-channel interference, or the inter-channel interference is smaller, and normal communication of the WiFi module and/or the bluetooth module is not affected yet. Because the bluetooth module adopts frequency hopping communication, the anti-interference capability of the bluetooth module is generally stronger than that of the WiFi module, therefore, the rssi value of the WiFi communication can be used as a representative index of inter-channel interference, and the bluetooth module can be generally considered to be undisturbed or disturbed to a smaller extent under the condition that the first rssi value is not smaller than the rssi threshold value of the corresponding channel. Therefore, in the case that the determination result of step 304 is "no", step 307 may be entered, that is, when the first rsi value is greater than or equal to the rsi threshold value of the corresponding channel, the operation mode is set in the FDD mode, and in the case that the determination result of step 304 is "yes", step 305 is entered, in step 305, the operation mode of the wireless device is set to TDD mode, in which the wireless device performs time-sharing response to the data transmission request of the WiFi module and the data transmission request of the bluetooth module, so that the data rate is about half that of the FDD mode, but in TDD mode, the influence of inter-channel interference on the communication effect of the WiFi module and the bluetooth module may be effectively avoided.

Then, in step 306, a first time interval is waited, and then step 301 is returned to perform the judgment of the AP connection of the WiFi module, and the like, which is not described herein. In addition, after step 307 is entered from step 301, step 302 or step 304, it is similarly necessary to return to step 301 after a first time interval to periodically monitor the operating state of the wireless device and whether a switch of operating modes is necessary.

As can be seen from the flowchart shown in fig. 3, the operation mode is set to TDD mode only when the WiFi module is connected to the AP, wiFi and bluetooth and the first rssi value indicates that the inter-channel interference may have affected its normal communication, and the wireless device may operate in FDD mode with higher data rate when the WiFi module is not connected to the AP and/or the first rssi value of the WiFi module is not less than the rssi threshold of the corresponding channel, so that the overall data transmission efficiency of the wireless device is higher.

In some embodiments, considering instability of a wireless channel or inaccuracy of signal detection, an rssi value of WiFi communication may have short-time fluctuation, and sporadic singular values may also occur, in order to reduce influence of accidental factors, a plurality of rssi values of a channel being used by a WiFi module in a second time interval before a current time is acquired, the plurality of rssi values may be smoothed, and the smoothed rssi value is taken as a first rssi value. Specifically, by way of example only, a buffer unit of a certain capacity may be provided in the wireless device, so as to temporarily store a plurality of rssi values measured by the WiFi module receiver for a period of time (for example, a time of a second time interval length), and when it is required to obtain a first rssi value of a channel being used by the WiFi module, the plurality of rssi values may be read from the buffer unit and subjected to corresponding smoothing processing, for example, an average value of the rssi values measured in the last three times may be obtained as the first rssi value. In other embodiments, the rssi value measured by the receiver may be processed as in equation (1) and stored as the first rssi value in the buffer unit:

wherein n is the number of cache units, indicating that n rssi values can be stored;

After arriving, firstly shifting the earliest rssi value out of the buffer unit, and shifting other rssi values in turnThen each +.>

The values are subjected to weighted smoothing in formula (1) to obtain a processed +.>

As a first rssi value, and stored in a buffer unit.

In other embodiments, any suitable algorithm may be used to obtain the first rssi value, which is not limited in this application, so long as the probability of erroneous judgment caused by the sporadic singular value can be reduced to some extent.

In some embodiments, the WiFi module and the bluetooth module may use the same antenna in the same frequency band (e.g., the 2.4GHz frequency band), and the channels/channel sets used by the WiFi module and the bluetooth module may be planned in advance, so that they may have a sufficient frequency space as much as possible when full duplex data transmission in FDD mode is adopted, and the channels may have better isolation when multiplexing the same antenna, and even if the WiFi module and the bluetooth module cause inter-channel interference due to insufficient isolation between channels in independent operation, the interfered condition of the channels may be conveniently, timely and accurately identified by adopting the control method for the operation mode of the wireless device according to the embodiment of the present application as shown in fig. 2 or fig. 3, and the operation mode of the wireless device may be set to TDD mode accordingly to avoid the influence of interference. Therefore, compared with the prior art that when the WiFi and the Bluetooth work in the same frequency band and share the same antenna, the working mode of the wireless device is set to TDD to avoid mutual interference, the control method provided by the embodiment of the application supports that the FDD mode is still adopted when the same antenna is multiplexed in the same frequency band, so that the wireless device has higher overall data rate.

In some embodiments, the rssi threshold values for the various channels previously stored as described above may be tested prior to shipment of the wireless device. Specifically, for example, the test may be performed based on the fact that the WiFi module and the bluetooth module are independently operated in the same frequency band before shipment, so that the WiFi module sequentially operates on each channel that may be used, and performance indexes of the corresponding wireless device are measured respectively, so as to determine rssi thresholds corresponding to each channel. Practice shows that, for different channels, the rssi threshold values measured and calculated by the different channels may also have a large difference, for example, the rssi threshold value of each channel may be distributed in the range of 5dbm-50dbm, which is influenced by whether the bluetooth module uses the channel or not and the usage mode, so that the rssi threshold values need to be measured and calculated separately for the channels that may be used by each WiFi module.

Specifically, the performance index of the wireless device includes, but is not limited to, one of the interference level of the bluetooth module, the packet error rate (Packet Error Rate, PER) of the wireless device, and the antenna receiving performance index of the wireless device, or a combination thereof, and on the basis thereof, the rssi threshold value of each channel may be specifically determined according to one of the following methods.

In some embodiments, the first rssi threshold when the performance index of the bluetooth module drops to the first threshold may be used as the rssi threshold for the corresponding channel. For example only, the degree of jamming during playing of bluetooth audio may be used as a performance index of the bluetooth module, mild jamming may be used as a first threshold, that is, the strength of the input signal is adjusted during testing, and the rssi threshold of the WiFi module measured when the bluetooth audio playing begins to occur mild jamming is used as the rssi threshold of the current test channel.

In some embodiments, the strength of the input signal may also be adjusted during the test, and the second rssi threshold of the WiFi module is used as the rssi threshold of the corresponding channel when the packet error rate of the wireless device drops to the second threshold. In general, when there is interference between channels, the packet error rate of the wireless device will decrease, and due to the increase of retransmission times, the data throughput rate of the system will also decrease, so when the packet error rate of the wireless device decreases to the second threshold, the second rssi threshold of the WiFi module may be used as the rssi threshold of the corresponding channel. In addition, the packet error rate of the wireless device may be calculated based on the combined packet error rates of both WiFi communication and bluetooth communication, and the specific value of the second threshold of the packet error rate may be determined according to the actual performance requirement of the wireless device, which is not described herein. In other embodiments, other performance indicators similar to the packet error rate may be used, which is not limited in this application.

In other embodiments, the strength of the input signal may also be adjusted during the test and a third rssi threshold value when the antenna reception performance index of the wireless device drops to the third threshold value is used as the rssi threshold value of the corresponding channel. Specifically, for example, TIS (Total Isotropic Sensitivity, total omni-directional sensitivity) of an antenna may be used as an antenna receiving performance index, and when the TIS index of the antenna is reduced, it is generally indicated that there is an interference factor in a radio frequency circuit in the wireless device, for example, interference caused by insufficient isolation of a channel or an antenna when the bluetooth module and the WiFi module operate in FDD full duplex. Therefore, the third rssi threshold when the reception performance index of the antenna such as TIS drops to the third threshold of the corresponding TIS can be regarded as the rssi threshold of the corresponding channel. It may be understood that when different antenna receiving performance indexes are selected, the third threshold is a specific threshold corresponding to the performance index, and the specific value may be determined according to the actual performance requirement of the wireless device, which is not limited in this application.

In other embodiments, the rssi threshold for the corresponding channel may also be obtained by weighted averaging the first, second, and third rssi thresholds as described above. For example only, the arithmetic mean of the first, second, and third rssi thresholds may be simply taken as the rssi threshold for the corresponding channel, for example. In other cases, the weights of the three rssi thresholds may also be set according to the performance and metrics that the wireless device is focused on, e.g., the weight of the first rssi threshold, the weight of the second rssi threshold, and the weight of the third rssi threshold may be set in association with the performance metrics requirements of the wireless device on the bluetooth module, e.g., when the wireless device has a higher requirement for bluetooth jamming, the weight of the second rssi threshold may be set to a higher value accordingly, and the weight of the first rssi threshold and the weight of the third rssi threshold may be decreased accordingly. On the premise that the rssi threshold value of the corresponding channel is determined in the above manner, when the channel interfered condition is determined based on the comparison result of the first rssi value and the rssi threshold value of the corresponding channel and the operation mode is set to the TDD mode accordingly, the degradation condition of the performance index of interest of the wireless device can be improved with more pertinence.

In addition, it should be noted that, in the testing process before the wireless device leaves the factory, the process of measuring the rssi value under the different transmitted signal intensities is generally performed, and similarly, the antenna receiving performance index and the like are also tested, so that the process of determining the rssi threshold value of the corresponding channel in the embodiment of the present application generally does not need to additionally add testing measurement equipment, even does not need to excessively change the testing process, only needs to perform calculation processing based on the measured values under the above various boundary conditions, and does not excessively increase the testing time and the workload of the tester.

There is also provided in accordance with an embodiment of the present application a wireless device, some of which have been described in detail in connection with fig. 1. In other embodiments, a wireless device according to embodiments of the present application may further include a memory configured to store an rssi threshold value of each channel, where the rssi threshold value of each channel is determined based on a measured performance index of the wireless device when the WiFi module is operating in each channel when the WiFi module and the bluetooth are both independently operating before shipment.
