The data transmission method provided by the embodiment of the present application is described in detail below with reference to the accompanying drawings through specific embodiments and application scenarios thereof.
Referring to fig. 1, fig. 1 is a flowchart illustrating steps of a data transmission method for an application icon provided in an embodiment of the present application, where the method may include the following steps:
Here, the method provided by the embodiment is introduced with reference to fig. 2, and with reference to fig. 2, fig. 2 is a schematic structural diagram of an electronic device provided in the embodiment of the present application, where the electronic device includes a WiFi module, a radio frequency module, a modem module, and a processor of the electronic device, and in a process of starting up the electronic device, the WiFi module of the electronic device sends a WiFi signal through a radio frequency link of a target frequency band, where the target frequency band may be a 2.4G radio frequency band or a 5G radio frequency band. If the electronic device only supports 2.4G WiFi, the target frequency band is a 2.4G wireless frequency band, the radio frequency link of the 2.4G wireless frequency band includes a radio frequency link 0(chain0) and a radio frequency link 1(chain 1) of 2.4G WiFi, and the WiFi module of the electronic device may sequentially transmit a WiFi signal through the radio frequency link 0 of the 2.4G WiFi and transmit a WiFi signal through the radio frequency link 1 of the 2.4G WiFi. If the electronic device only supports 5G WiFi, the target frequency band is a 5G wireless frequency band, the radio frequency link of the 5G wireless frequency band comprises a radio frequency link 0(chain0) and a radio frequency link 1(chain 1) of the 5G WiFi, and the WiFi module of the electronic device sequentially transmits WiFi signals through the radio frequency link 0 of the 5G WiFi and transmits WiFi signals through the radio frequency link 1 of the 5G WiFi. If the electronic device supports 2.4G WiFi and 5G WiFi, the target frequency band includes a target frequency band 1 and a target frequency band 2, the target frequency band 1 may be a 2.4G wireless frequency band, and the target frequency band 2 is a 5G wireless frequency band, and the electronic device sequentially transmits a WiFi signal through a radio link 0(chain0) of 2.4G WiFi, a radio link 1(chain 1) of 2.4G WiFi, a radio link 0(chain0) of 5G WiFi, and a radio link 1(chain 1) of 5G WiFi.
As shown in fig. 2, after the electronic device sends a WiFi signal through a radio frequency link of a certain wireless frequency band, a radio frequency module of the electronic device may receive the WiFi signal sent by the radio frequency link, and obtain power of the WiFi signal sent by the radio frequency link through a modulation and demodulation module. It should be noted that, in the process of starting up the electronic device, only one radio frequency link is used to transmit a WiFi signal at a time, and the sequence of transmitting WiFi signals by the radio frequency link is fixed, and if the electronic device does not receive a WiFi signal within a preset time, it may be determined that a certain radio frequency link fails.
And 102, determining the state of the radio frequency link according to the power of the WiFi signal corresponding to the radio frequency link.
Taking the example that the electronic device supports 2.4G WiFi and 5G WiFi, a WiFi module of the electronic device sequentially sends a WiFi signal through a radio frequency link 0(chain0) of 2.4G WiFi, a radio frequency link 1(chain 1) of 2.4G WiFi, a radio frequency link 0(chain0) of 5G WiFi, and a radio frequency link 1(chain 1) of 5G WiFi, if the radio frequency module shown in fig. 2 receives a WiFi signal corresponding to the radio frequency link 0 of 2.4G WiFi, the modulation and demodulation module demodulates the power of the WiFi signal corresponding to the radio frequency link 0 of 2.4G WiFi and is greater than or equal to a preset threshold value, the state of the 2.4G WiFi radio frequency link 0 is identified by the identifier 1, the state identifier 1 of the 2.4G WiFi radio frequency link 0 is sent to the WiFi module through the processor, and the WiFi module can determine that the state of the 2.4G WiFi radio frequency link 0 is a normal state according to the state identifier 1 of the 2.4G WiFi radio frequency link 0; if the power of the WiFi signal corresponding to the radio frequency link 0 of the 2.4G WiFi is smaller than the preset threshold value, the state of the radio frequency link 1 of the 2.4G WiFi is identified by 0, the state identification 0 of the radio frequency link 1 of the 2.4G WiFi is sent to the WiFi module through the processor, and the WiFi module can determine that the state of the radio frequency link 0 of the 2.4G WiFi is an abnormal state according to the state identification 0 of the radio frequency link 1 of the 2.4G WiFi. Similarly, if the power of the WiFi signal corresponding to the radio frequency link 1 of the 2.4G WiFi is greater than or equal to the preset threshold, the WiFi module determines that the state of the radio frequency link 1 of the 2.4G WiFi is a normal state; if the power of the WiFi signal corresponding to the radio frequency link 1 of the 2.4G WiFi is smaller than the preset threshold, the WiFi module determines that the state of the radio frequency link 1 of the 2.4G WiFi is an abnormal state. Likewise, the WiFi module may determine the status of radio link 0 for 5G WiFi and the status of radio link 1 for 5G WiFi.
And 103, accessing the access point through a preset radio frequency link under the condition that the state of a preset radio frequency link in two radio frequency links of the target frequency band is a normal state and the state of the other radio frequency link is an abnormal state, and performing data transmission with the access point by adopting a single-input single-output SISO mode.
With reference to the foregoing example, for the target frequency band 1, one of the two radio frequency links of the target frequency band 1 is preset to be the radio frequency link 0 of 2.4G WiFi; for the target frequency band 2, one of the two radio frequency links of the target frequency band 2 is a radio frequency link 1 of 5G WiFi. In the prior art, for an electronic device supporting 2.4G WiFi, during a boot process of the electronic device, an access point is accessed through a radio frequency link 0 of the 2.4G WiFi, and data transmission is performed between an MIMO mode and the access point after the access point is accessed, however, if a radio frequency link 1 of the 2.4G WiFi fails, the electronic device may not receive a part of data sent by the access point, the electronic device may switch back to the SISO mode for data transmission, and after the electronic device is in the SISO mode for a period of time, the electronic device and the access point may perform data transmission in the MIMO mode, which causes the WiFi of a user to switch between the SISO mode and the MIMO mode all the time, and causes a problem of WiFi network fluctuation. For the electronic device supporting 5G WiFi, in the process of starting up the electronic device, the electronic device accesses to the access point through the radio frequency link 1 of 5G WiFi, and after accessing to the access point, data transmission is performed between the MIMO mode and the access point, however, if the radio frequency link 0 of 5G is failed, similar to the electronic device supporting 2.4G WiFi, the WiFi of the user is always switched between the SISO mode and the MIMO mode, which causes the problem of WiFi network fluctuation.
In this embodiment, when the state of the radio frequency link 0 of the target frequency band 1 is a normal state and the state of the radio frequency link 1 of the target frequency band 1 is an abnormal state, the WiFi module accesses the access point through a preset radio frequency link (i.e., the radio frequency link 0 of the target frequency band 1) of the target frequency band 1, and performs data transmission with the access point in the SISO mode. When the state of the radio frequency link 0 of the target frequency band 2 is an abnormal state and the state of the radio frequency link 1 of the target frequency band 2 is a normal state, the access point is accessed through a preset radio frequency link (i.e., the radio frequency link 1 of the target frequency band 2) of the target frequency band 2, and the WiFi module shown in fig. 2 of the electronic device performs data transmission with the access point in a SISO mode. Therefore, the problem that WiFi network fluctuation is caused because WiFi of a user is always switched between a SISO mode and a MIMO mode when a MIMO mode and an access point are adopted for data transmission under the condition that the state of a preset radio frequency link of a target frequency band is a normal state and the state of the other radio frequency link of the target frequency band is an abnormal state can be solved.
In the data transmission method provided in this embodiment, in a process of starting up the electronic device, power of a WiFi signal corresponding to a radio frequency link received by the electronic device is obtained, where the WiFi signal is sent by a WiFi module of the electronic device through the radio frequency link of a target frequency band, a state of the radio frequency link is determined according to the power of the WiFi signal corresponding to the radio frequency link, and when a state of a preset radio frequency link of two radio frequency links of the target frequency band is a normal state and a state of the other radio frequency link is an abnormal state, the access point is accessed through the preset radio frequency link of the target frequency band, and data transmission is performed with the access point in a SISO mode. The problem that in the prior art, under the condition that the state of one preset radio frequency link in two radio frequency links of a target frequency band is a normal state and the state of the other radio frequency link is an abnormal state, the data transmission is still carried out by adopting an MIMO mode and an access point, so that WiFi of a user is always switched between a SISO mode and a MIMO mode, and WiFi network fluctuation is caused is solved.
Referring to fig. 3, fig. 3 is a flowchart illustrating steps of another data transmission method for an application icon provided in an embodiment of the present application, where the method may include the following steps:
Determining the state of the radio frequency link according to the power of the WiFi signal corresponding to the radio frequency link can be implemented as follows:
determining the state of the radio frequency link to be a normal state under the condition that the power of the WiFi signal corresponding to the radio frequency link is greater than or equal to a preset threshold value;
and under the condition that the power of the WiFi signal corresponding to the radio frequency link is smaller than a preset threshold value, determining that the state of the radio frequency link is an abnormal state.
It should be noted that the preset threshold is determined according to the insertion loss of the rf front-end device of the electronic device, the antenna isolation of the WiFi antenna of the electronic device, and the preset target transmission power of the WiFi antenna.
For example, the preset target transmission power of the WiFi antenna is 18dbm, the antenna isolation of the WiFi antenna is 15 decibels (15db), the insertion loss of the radio frequency device is 10db, and the power reaching the radio frequency module can reach 18dbm-15db-10db ═ 7 dbm. In the field of communications, the industry dictates that the transmit power of an antenna be 18dbm, but in practice, the transmit power of an antenna may fluctuate around 18dbm, and thus the power reaching the radio frequency module may fluctuate around-7 dbm, leaving a certain margin, and thus the preset threshold may be set to-10 dbm.
And 303, accessing to the access point through the preset radio frequency link under the condition that the states of the two radio frequency links are both normal states, and performing data transmission with the access point by adopting a multiple-input multiple-output (MIMO) mode.
For example, if the state of the radio frequency link 0 and the state of the radio frequency link 1 of the target frequency band 1 are both normal states when the target frequency band is the target frequency band 1, the access point may be accessed through the radio frequency link 0 of the target frequency band 1, and since the state of the radio frequency link 0 and the state of the radio frequency link 1 of the target frequency band 1 are both normal states, it means that neither the radio frequency link 0 nor the radio frequency link 1 of the target frequency band 1 has a failure, and data transmission between the MIMO mode and the access point may be performed. Under the condition that the target frequency band is the target frequency band 2, if the state of the radio frequency link 0 of the target frequency band 2 and the state of the radio frequency link 1 are both normal states, the access point can be accessed through the radio frequency link 1 of the target frequency band 2, and since the state of the radio frequency link 0 of the target frequency band 2 and the state of the radio frequency link 1 are both normal states, it means that neither the radio frequency link 0 of the target frequency band 2 nor the radio frequency link 1 has a fault, and data transmission between the MIMO mode and the access point can be performed.
And step 304, when the state of one preset radio frequency link in the two radio frequency links of the target frequency band is a normal state and the state of the other radio frequency link is an abnormal state, accessing the access point through the preset radio frequency link, and performing data transmission with the access point in a single-input single-output SISO mode.
For example, when the target frequency band is the target frequency band 1, if the state of the preset radio frequency link of the target frequency band 1 (the preset radio frequency link of the target frequency band 1 is the radio frequency link 0 of the target frequency band 1) is a normal state, and the state of the other radio frequency link 1 of the target frequency band 1 is an abnormal state, the access point is accessed through the radio frequency link 0 of the target frequency band 1, and data transmission is performed with the access point in the SISO mode. When the target frequency band is the target frequency band 2, if the state of the preset radio frequency link of the target frequency band 2 (the preset radio frequency link of the target frequency band 2 is the radio frequency link 1 of the target frequency band 2) is a normal state, and the state of the other radio frequency link 0 of the target frequency band 2 is an abnormal state, accessing to the access point through the radio frequency link 1 of the target frequency band 1, and performing data transmission with the access point in a SISO mode.
And 305, accessing the access point through the other radio frequency link under the condition that the state of the preset radio frequency link is an abnormal state and the state of the other radio frequency link is a normal state, and performing data transmission with the access point by adopting a SISO mode.
For example, when the target frequency band is the target frequency band 1, if the state of the preset radio frequency link of the target frequency band 1 (the preset radio frequency link of the target frequency band 1 is the radio frequency link 0 of the target frequency band 1) is an abnormal state, and the state of the radio frequency link 1 of the target frequency band 1 is a normal state, the access point is accessed through the radio frequency link 1 of the target frequency band 1, and data transmission is performed with the access point in the SISO mode.
When the target frequency band is the target frequency band 2, if the state of the preset radio frequency link of the target frequency band 2 (the preset radio frequency link of the target frequency band 2 is the radio frequency link 1 of the target frequency band 2) is an abnormal state, and the state of the radio frequency link 0 of the target frequency band 2 is a normal state, the radio frequency link 0 of the target frequency band 1 is accessed to the access point, and a SISO mode is adopted for data transmission with the access point.
In the prior art, for the electronic equipment supporting 2.4G WiFi, the electronic equipment is accessed to an access point by default through a radio frequency link 0 of a 2.4 wireless frequency band; for an electronic device supporting 5G WiFi, the electronic device is accessed to an access point through a radio frequency link 1 of a 5 wireless frequency band by default. Therefore, if the radio frequency link 0 of the 2.4G wireless frequency band fails, the radio frequency link 1 of the 2.4G wireless frequency band does not fail; or, if the radio frequency link 1 in the 5G wireless band fails and the radio frequency link 0 in the 2.4G wireless band does not fail, the electronic device may not access the access point although the received signal is strong. In this embodiment, when the state of the radio frequency link 0 of the target frequency band 1 is an abnormal state and the state of the radio frequency link 1 of the target frequency band 1 is a normal state, the access point is accessed through the radio frequency link 1 of the target frequency band 1, and when the state of the radio frequency link 1 of the target frequency band 2 is an abnormal state and the state of the radio frequency link 0 of the target frequency band 2 is a normal state, the access point is accessed through the radio frequency link 0 of the target frequency band 2. Therefore, the problem that the electronic equipment cannot access the access point under the condition that the preset radio frequency link of the target frequency band fails but the other radio frequency link fails in the prior art can be solved.

The problem that in the prior art, under the condition that the state of one preset radio frequency link in two radio frequency links of a target frequency band is a normal state and the state of the other radio frequency link is an abnormal state, the data transmission is still carried out by adopting an MIMO mode and an access point, so that WiFi of a user is always switched between a SISO mode and a MIMO mode, and WiFi network fluctuation is caused is solved.
