Detailed Description

Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, like numbers in different drawings represent the same or similar elements unless otherwise indicated. The implementations described in the exemplary embodiments below are not intended to represent all implementations consistent with the present disclosure. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the present disclosure, as detailed in the appended claims.

Fig. 1 is a schematic flowchart of a frequency band resource processing method according to an embodiment of the present disclosure, and as shown in fig. 1, the frequency band resource processing method specifically includes the following processing steps:

and S11, dividing the frequency band commonly supported by the plurality of wireless processing modules in the electronic equipment into sub-frequency bands matched with the number of the wireless processing modules.

In the embodiments of the present disclosure, the wireless processing module mainly refers to an antenna system of an electronic device, and the wireless processing module can provide wireless communication capability for the electronic device. The wireless processing module can comprise a WIFI antenna system, a BT antenna system, or 4G and 5G antenna systems.

The electronic devices may include internet of things devices, cell phones, tablet computers, game machines, personal digital assistants, and the like. The electronic device is provided with more than two antenna systems, the more than two antenna systems support a common frequency band, that is, the more than two antenna systems need to use the same frequency band resource for communication, at this time, because the electronic device has a small volume, the distance between the antenna systems is relatively small, which causes mutual interference between the more than two antenna systems due to the use of the same frequency band, and affects the communication quality between the more than two antenna systems. The embodiment of the disclosure is directed to the situation that the two or more antenna systems simultaneously work and have the same frequency band attribute to cause interference, by dividing the common frequency band of the antenna systems by sub-frequency bands, the two or more antenna systems do not generate signal interference even though simultaneously work in a frequency division manner.

In the embodiment of the present disclosure, a frequency band commonly supported by a plurality of wireless processing modules needs to be divided into sub-frequency bands matching with the number of the wireless processing modules, that is, the frequency band needs to be divided into sub-frequency bands not less than the number of the wireless processing modules, a frequency band resource may be divided into continuous frequencies, and a discontinuous frequency band resource may also be divided into one sub-frequency band according to a usage convention or an actual need of the frequency resource. The frequency bands may be equally or unequally assigned to the center frequency.

By dividing the frequency band into a plurality of sub-frequency bands, the plurality of wireless processing modules can select corresponding sub-frequency bands from the sub-frequency bands as operating frequency bands, and other wireless processing modules can select other sub-frequency bands, so that the sub-frequency bands selected by the plurality of wireless processing modules are different, and thus, even if the plurality of wireless processing modules operate simultaneously, mutual interference cannot be generated, or mutual interference among the plurality of wireless processing modules is relatively low.

In the embodiment of the present disclosure, in practical application, a sub-band with a large frequency center difference may be selected between wireless processing modules with close distances as needed, so as to further reduce mutual interference when multiple wireless processing modules operate simultaneously.

Specifically, if the total number of wireless processing modules in the electronic device is N, the frequency band may be divided into M sub-frequency bands, where M is greater than or equal to the number N of wireless processing modules. In the embodiment of the present disclosure, the number of the divided sub-bands is not suitable to be too large, and when the number of the divided sub-bands is too large, the sub-bands may not be enough to meet the communication requirement of a single wireless processing module.

As a preferred implementation manner, the number M of sub-bands divided by the total frequency band is equal to the number N of the wireless processing modules. Even if a plurality of wireless processing modules work simultaneously, at least one sub-frequency band can be allocated to each wireless processing module, so that the mutual interference among the wireless processing modules is reduced while the normal work of the wireless processing modules is ensured, and the communication quality of the wireless processing modules is ensured.

S12, in response to the request for using the frequency band from the first wireless processing module, detecting the sub-frequency bands occupied by other wireless processing modules.

In the embodiment of the present disclosure, when a wireless processing module in an electronic device needs to operate as a certain antenna system, a sub-band different from a sub-band used by the antenna system in a current operating state needs to be selected according to a current sub-band usage situation, so that the sub-bands selected among the antenna systems do not interfere with each other, or signal interference among the antenna systems can be greatly reduced.

It should be understood by those skilled in the art that the first wireless processing module of the embodiments of the present disclosure is intended to be generic and not limiting. The first wireless processing module may be any one of wireless processing modules.

Specifically, when the electronic device determines that a certain antenna system needs to be enabled, it first queries a sub-band situation occupied by another antenna system currently in an operating state, and selects a wireless communication resource for the antenna system to be enabled in a sub-band other than the sub-band occupied by the other antenna system, so as to avoid generating mutual interference with the other antenna system after being enabled and affecting respective communication quality.

S13, allocating at least one of the unoccupied sub-bands of the other wireless processing modules to the first wireless processing module.

In the embodiment of the present disclosure, when it is determined that there are a plurality of unoccupied sub-bands, one sub-band may be allocated to the first wireless processing module, and of course, a plurality of sub-bands may also be allocated, where the specific requirement is determined according to the communication requirement of the first wireless communication unit, the sub-band allocation policy, and the like.

In the embodiment of the present disclosure, at least one of the unoccupied frequency subbands is allocated to the first wireless processing module, and the first wireless processing module is triggered to gate the frequency subband to be allocated, where the frequency subband to be allocated is determined for the first wireless processing module in the unoccupied frequency subbands.

As an implementation manner, a plurality of band pass filters matched with the number of the sub-bands are arranged in the wireless processing module in the embodiment of the present disclosure, and each band pass filter supports one sub-band; and setting a gating switch for each band-pass filter. The band-pass filter can pass the signal wave corresponding to the sub-band supported by the band-pass filter, and filter the signal waves of other frequency bands, so that the working frequency band of the wireless processing module can be realized by gating the band-pass filter in the wireless processing module, and the wireless processing module is only suitable for the allocated sub-band to carry out communication. The embodiment of the disclosure can realize the control of the on or off of the band-pass filter by arranging the corresponding gating switch on the band-pass filter, thereby greatly facilitating the allocation of the sub-band resources of the wireless processing module. Triggering the first wireless processing module to gate the sub-band to be allocated comprises: and turning on a gating switch of a band-pass filter supporting the sub-band to be allocated in the first wireless processing module, so that the first wireless processing module enables the sub-band to be allocated.

In the embodiment of the present disclosure, the wireless processing module includes a transceiver unit and an antenna, and a plurality of bandpass filters are connected in parallel, and a plurality of bandpass filters connected in parallel are connected between the transceiver unit and the antenna, and if necessary, a subband is allocated to a certain wireless processing module, and the subband allocation of the wireless processing module can be realized by gating the bandpass filter corresponding to the subband to be allocated. It should be noted that the sub-bands may be allocated in other manners, which are only examples and should not be construed as limiting the embodiments of the present disclosure.

In the embodiment of the present disclosure, when the wireless processing module is initially powered on to operate, the gating switches of each band-pass filter in the first wireless processing module are turned on one by one to determine a sub-band where the wireless processing module and a communication peer are synchronized, and the synchronized sub-band is used as a working band. Specifically, under the condition that the electronic device is initially powered on, the wireless processing module is also in an initial power-on state at this time, and one or more sub-bands need to be selected from all sub-bands in the frequency band, at this time, the electronic device may control the band-pass filter in the powered-on wireless processing module to gate one by one, so as to perform handshake processing, such as synchronization, with the opposite communication terminal until a wireless channel is established with the opposite communication terminal, and use the sub-band currently establishing the communication channel as the operating frequency band of the wireless processing module. Based on this, the electronic device may detect the operating sub-bands of the wireless processing module based on the open/close state of the gating switch of the band-pass filter in the wireless processing module, etc., to determine the sub-band situation currently used by the wireless processing module, determine which sub-bands are occupied, and which sub-bands are idle.

In an embodiment of the present disclosure, detecting a plurality of sub-bands occupied by other wireless processing modules in the wireless processing module specifically includes: and respectively detecting the band-pass filter for turning on the gating switch in each wireless processing module, and determining the sub-frequency band occupied by the wireless processing module based on the gated band-pass filter.

The embodiment of the disclosure enables more than two wireless processing modules supporting the same frequency band to select different working sub-frequency bands, thereby avoiding mutual interference caused when the more than two wireless processing modules start communication simultaneously, improving the communication quality of the more than two wireless processing modules, and enabling an electronic device user to have better use experience.

The essence of the technical solution of the embodiments of the present disclosure is further clarified by the application scenarios below.

In the following, taking an electronic device as an IOT device as an example, the IOT device is provided with a BT antenna and a WiFi antenna at the same time. The BT antenna and the WiFi antenna work in a 2.4GHz frequency band, and if the BT antenna and the WiFi antenna work at the same time, the problems of same frequency interference, stray interference and the like can be caused.

Fig. 2 is a schematic diagram of an application scenario shown in the embodiment of the present disclosure, and as shown in fig. 2, taking an IOT device as an example, the IOT device includes a BT transceiver and a Wi-Fi transceiver, and the BT transceiver and the Wi-Fi transceiver in the device are simultaneously operated. The IOT equipment establishes a first communication connection with communication equipment such as a mobile phone, a computer and the like through the BT, and achieves command control, data interaction and other data transmission between the IOT equipment and the communication equipment. Meanwhile, the IOT equipment establishes connection with a router of the Internet through Wi-Fi to achieve network access.

This scenario requires the BT antenna system and the Wi-Fi antenna system in the IOT device to work simultaneously, and therefore, there are two main problems: because the working frequency bands of the BT antenna system and the Wi-Fi antenna system are the same, when the BT antenna system and the Wi-Fi antenna system work simultaneously, noise interference is generated due to signal frequency conflict, and further function abnormity is caused; unlike time-sharing operation, if the BT antenna system and the Wi-Fi antenna system operate simultaneously, the IOT device cannot share an antenna, but needs the BT antenna system and the Wi-Fi antenna system to communicate based on independent antennas ANT1 and ANT 2. Because the IOT device is small in size, isolation between antennas cannot be guaranteed, which also affects the operating performance of BT antenna systems and Wi-Fi antenna systems.

In view of the above, the embodiments of the present disclosure provide a method for optimizing coexistence of a BT antenna system and a Wi-Fi antenna system in an IOT device and ensuring communication performance thereof. Specifically, the effective planning of the working frequency of the Wi-Fi/BT is realized by adding a plurality of band-pass filters (BPF) and Switches (SW) between the Wi-Fi transceiver and the BT transceiver and respective antennas thereof, and meanwhile, the isolation between the Wi-Fi transceiver and the BT transceiver is increased, and the interference is effectively reduced. In the embodiment of the disclosure, a plurality of band pass filters are connected in parallel, and each band pass filter can gate a part of frequency bands in Wi-Fi/BT working frequency and filter signal waves of other frequency bands, so that the BT antenna system and the Wi-Fi antenna system work on the part of frequency bands in the working frequency, and if a sub-frequency band with non-coincident frequency is configured for the BT antenna system and the Wi-Fi antenna system, the BT antenna system and the Wi-Fi antenna system can greatly avoid mutual interference when working at the same time.

Fig. 3 is a schematic structural diagram of an IOT device according to an embodiment of the present disclosure, and as shown in fig. 3, a specific structure of the IOT device according to the embodiment of the present disclosure is shown, and the IOT device shown in fig. 3 supports a BT antenna system and a Wi-Fi antenna system to simultaneously operate, and can avoid mutual interference between the two antenna systems to the maximum extent. The two-antenna system shown in fig. 3 is only used as an example for illustration, and those skilled in the art should understand that any electronic device that adopts a multi-antenna system, such as a three-antenna system, a four-antenna system, etc., which adopts the core idea of the technical solution of the present disclosure, should have the same application scenario as the two-antenna system, and since all examples cannot be exhausted, the technical solution that adopts the frequency band allocation manner of the present disclosure between the multi-antenna systems should fall within the protection scope of the present disclosure.

The IOT device shown in fig. 3 includes a microprocessor system MCU, a BT antenna system including a Wi-Fi transceiver and antenna ANT1, and a Wi-Fi antenna system including a BT transceiver and antenna ANT 2. The frequency bands supported by the antenna ANT1 and the antenna ANT2 are completely the same, and may be the same or similar antennas. It should be noted that the embodiment of the present disclosure also supports a scenario that the operating frequency bands supported by more than two antenna systems in the electronic device are partially overlapped, and the technical solution of the embodiment of the present disclosure may still be adopted when the overlapped frequency bands need to be simultaneously opened.

The working frequency ranges of the BT antenna system and the Wi-Fi antenna system are both 2.4GHz-2.48 GHz. Fig. 4 is a schematic diagram of frequency band division according to an embodiment of the present disclosure, and as shown in fig. 4, the embodiment of the present disclosure divides the operating frequency bands 2.4GHz-2.48GHz of the BT antenna system and the Wi-Fi antenna system into two sub-frequency bands, which are a sub-frequency band of 2.4GHz-2.44GHz and a sub-frequency band of 2.44GHz-2.48GHz, respectively. It will be understood by those skilled in the art that the operating frequency may be divided into more than two sub-bands, as long as the communication bandwidth requirements of each antenna system are ensured. Of course, the sub-bands may be divided into non-continuous frequencies, such as a sub-band with 2.4GHz-2.42GHz and 2.46GHz-2.48GHz, a sub-band with 2.42GHz-2.46GHz, and the like. Particularly according to the actual configuration requirements of the frequency resources.

For the divided sub-bands of fig. 4, as shown in fig. 3, two parallel band-pass filters BPF1 and BPF2 may be respectively disposed in the Wi-Fi antenna system, a gate switch SW1 is disposed on a line connecting the BPF1 and BPF2 with the Wi-Fi transceiver, a gate switch SW2 is disposed on a line connecting the BPF1 and BPF2 with the antenna ANT1, and the MCU may gate the gate switches SW1 and SW2 through a GPIO bus, so that the Wi-Fi antenna system may use one of the two sub-bands to establish a communication channel. As in the foregoing subband division manner, if the BPF1 is gated, the Wi-Fi antenna system uses a subband of 2.4GHz to 2.44GHz for communication; if the BPF2 is gated, the Wi-Fi antenna system uses a sub-band of 2.44GHz-2.48GHz for communication.

As shown in fig. 3, two bandpass filters BPF3 and BPF4 connected in parallel may be respectively disposed in the BT antenna system, a gating switch SW3 is disposed on a line connecting the BPF3 and BPF4 with the BT transceiver, a gating switch SW4 is disposed on a line connecting the BPF3 and BPF4 with the antenna ANT2, and the MCU may perform gating control on the gating switches SW3 and SW4 through a GPIO bus, so that the BT antenna system may establish a communication channel using one of the two sub-bands. As in the foregoing subband division manner, if the BPF3 is gated, the BT antenna system uses a subband of 2.4GHz to 2.44GHz for communication; if the BPF4 is gated, the BT antenna system uses a sub-band of 2.44GHz-2.48GHz for communication.

Therefore, when the working channel of the Wi-Fi antenna system is determined to be in the range of 2.4-2.44GHz by the frequency sweep, the MCU controls the switches SW1 and SW2 to switch to the BPF1, and the SW3 and SW4 to switch to the BPF4, so that the working frequency of BT is limited to 2.44GHz-2.48GHz, the separation of the working frequencies of Wi-Fi and BT is realized, and the signal interference between the Wi-Fi and the BT when the Wi-Fi and the BT work simultaneously is reduced. Still with the aforementioned assumptions: the working bandwidth of the BPF1 and the BPF3 is 2.4GHz-2.44GHz, and the working bandwidth of the BPF2 and the BPF4 is 2.44GHz-2.48 GHz. When the working channel of the Wi-Fi is determined to be 2.4-2.44GHz by the sweep frequency, the switches SW1 and SW2 can be switched to BPF1 through the MCU, and SW3 and SW4 are switched to BPF4, so that the working frequency of BT can be limited to 2.44G-2.48GHz, the separation of the working frequencies of Wi-Fi and BT is realized, and the interference between two antenna systems when the two antenna systems work simultaneously is reduced. Similarly, when the working channel of the Wi-Fi is determined to be in the range of 2.44G-2.48GHz by the frequency sweep, the SW1 and the SW2 are switched to the BPF2, and the SW3 and the SW4 are switched to the BPF 3.

The embodiment of the disclosure reasonably controls the switch switching through the GPIO according to the working states of the Wi-Fi transceiver and the BT transceiver so as to select the corresponding filter, thereby realizing the effective distribution of the Wi-Fi frequency and the BT frequency.

The IOT device structure shown in fig. 3 is only an example, and only the dual band pass filters are taken as an example for description, and in addition, by increasing the number of band pass filters and reasonably configuring the bandwidths of the band pass filters and the switching of the switches, more flexible frequency planning can be realized.

By adopting the technical scheme of the embodiment of the disclosure, simultaneous work is really realized among multiple wireless processing modules, such as antenna systems, in the electronic equipment; by setting the configuration of the band-pass filter and the gating switch, the reasonable planning of the working frequency of the multi-antenna system can be realized, and the influence of interference caused by the isolation between the antenna systems is well compensated.
