In specific implementation, a plurality of filters of the same type capable of performing bandwidth selection or frequency band selection may be included, as long as Filters that enable bandwidth selection and band selection are all within the scope of the present invention. As shown in FIG. 4, a bandwidth selection filter (such as the sacrificial LTE bandwidth filter shown in FIG. 4) and a full-band filter (such as the LTE shown in FIG. 4) may be preset in the RF channel of the LTE. Band Filters Two filters are used to divide the LTE channel with the bandwidth selection filter into LTE channels with LTE bandwidth loss, and divide the LTE channel with full-band filter into LTE full-band channels. Specifically, the RF switch can be set in the RF channel of the LTE, and the bandwidth selection filter or one of the full-band filter is selected by the RF switch, so that the LTE channel with the LTE bandwidth loss is selected as the current LTE RF channel. Select the LTE full-band channel as the current LTE RF channel.

The bandwidth filter and the full-band filter described in this embodiment are only examples, and are not exhaustive. In specific implementation, a plurality of filters of the same type capable of performing bandwidth selection or frequency band selection may be included, as long as Filters that enable bandwidth selection and band selection are all within the scope of the present invention. As shown in FIG. 6, a bandwidth selection filter (such as the sacrificial LTE bandwidth filter shown in FIG. 6) and a full-band filter (such as the LTE shown in FIG. 6) may be preset in the RF channel of the LTE. Band filter) The LTE channel with the bandwidth selection filter is divided into LTE channels with LTE bandwidth loss, and the LTE channel with full-band filter is divided into LTE full-band channels. Specifically, an RF switch can be set in the RF channel of the LTE, and the bandwidth selection filter or one of the full-band filter is selected by the RF switch, so that the LTE channel with the LTE bandwidth loss is selected as the current LTE RF channel. Or choose LTE full-band channel as the current LTE RF channel. In addition, as shown in FIG. 6, a bandwidth selection filter (such as the sacrificial WiFi bandwidth filter shown in FIG. 6) and a full-band filter may be set in advance in the RF channel of the WiFi (as shown in FIG. 6). WiFi full-band filter) Two filters, the WiFi channel set with the bandwidth selection filter is divided into WiFi channels with WiFi bandwidth loss, and the WiFi channel with full-band filter is divided into WiFi full-band channels. It is also possible to divide a WiFi channel without a filter into a filterless channel. Specifically, it is also possible to set a single-pole three-throw shot in the RF channel of the WiFi. Frequency switch, select the bandwidth selection filter or one of the full-band filters through the RF switch or select no filter, so select the WiFi channel with WiFi bandwidth loss as the current WiFi RF channel, or select the WiFi full-band channel as the The current WiFi RF channel, or the filterless WiFi filterless channel, acts as the current WiFi RF channel. The terminal device divides the LTE RF channel into a channel with LTE bandwidth loss and an LTE full-band channel, and divides the RF channel of the WiFi into a channel with WiFi bandwidth loss and a full-band channel of WiFi, and WiFi without filtering. After the channel, the LTE channel can be selected as the current LTE radio channel or which WiFi channel is selected as the current WiFi radio channel according to the obtained LTE frequency information.

 In some feasible implementation manners, the terminal device may first acquire an LTE network signal from the base station, and determine, according to the acquired network signal, whether the LTE network has a coexistence problem with the WiFi network. Specifically, the LTE network signal obtained by the terminal device from the base station may include LTE frequency information such as frequency band information and frequency point information of the LTE. After obtaining the frequency information of the LTE, the terminal device may determine, according to the pre-stored frequency information of the WiFi, whether the difference between the frequency of the LTE and the frequency band of the WiFi is within a preset frequency difference range, and perform LTE RF channel and WiFi according to the determination result.

In some feasible implementation manners, it may be determined in advance by experiments or other means which frequency bands in the LTE frequency band may coexist with the WiFi interference problem, and it may be determined in advance which frequency bands have coexistence interference risk with the WiFi, and the frequency bands are specified. It is pre-stored in the terminal equipment for the risk band. After obtaining the LTE network signal, the terminal device determines whether the LTE frequency band is a risk frequency band according to the LTE frequency band information included in the obtained LTE network signal, and determines whether the acquired LTE frequency band of the LTE signal is the specified one. One of the risk bands can be used to determine whether there is a coexistence problem between LTE and WiFi. The frequency of the WiFi is pre-existing information in the terminal device.

The radio frequency performance of the other party may further determine whether the difference between the frequency point of the LTE and the frequency of the WiFi is within a preset frequency difference value according to the frequency of the LTE. If the terminal device determines that the difference between the frequency point of the LTE and the frequency of the WiFi is within a preset frequency difference value according to the frequency point of the LTE and the frequency of the WiFi, the LTE network and the WiFi may be determined at this time. There is a coexistence problem in the network. When the LTE network works with the WiFi network, it will interfere with each other's radio frequency capabilities.

That is, the frequency bands corresponding to some frequency points in the acquired LTE network are not used. In this case, in order to ensure the available channels of the WiFi and better ensure the radio performance of the LTE and the WiFi, the LTE channel with the LTE bandwidth loss can be set as the current LTE RF channel, and the WiFi full-band channel is set to the current WiFi. The RF channel ensures that LTE and WiFi can coexist and do not interfere with each other's RF performance, improving the user experience of the terminal device.
