Referring to fig. 2, fig. 2 is a flowchart illustrating an antenna control method according to an embodiment of the present disclosure. The method is applied to the electronic equipment and comprises the following steps:

step S101, when the wireless fidelity module transmits a wireless signal through a first antenna, current state information and weight values of a plurality of weight items of the first antenna are obtained.

The first antenna is an MIMO antenna, when a WiFi module of the electronic device works in an MIMO mode, the WiFi module transmits wireless signals through the MIMO antenna, wherein the MIMO antenna comprises a plurality of transmitting antennas and a plurality of receiving antennas, and a transmitting end and a receiving end of the WiFi module are respectively in communication connection with the wireless access point through the plurality of transmitting antennas and the plurality of receiving antennas and are used for transmitting wireless signals to the wireless access point through the MIMO antenna. When the WiFi module transmits wireless signals through the MIMO antenna, the current state information and the weight values of the plurality of weight items of the first antenna.

In some embodiments, the plurality of weight terms comprises a signal-to-noise value, a received signal strength indicator value, a packet error rate value, and a multipath delay value.

Wherein the obtaining of the current state information and the weight values of the plurality of weight items of the first antenna includes: and acquiring the signal-to-noise ratio value, the received signal strength index value, the packet error rate value and the multipath delay value of the first antenna, and acquiring weight values corresponding to the signal-to-noise ratio value, the received signal strength index value, the packet error rate value and the multipath delay value of the first antenna respectively.

The signal-to-noise ratio (SNR) value is generally a ratio of a received signal strength to a background noise strength. The signal-to-noise ratio is used for distinguishing useful WIFI signals and environmental noise in the WIFI chip. The larger the signal-to-noise ratio value is, the better the useful signal received by the WIFI chip is. For example, if the received signal strength is-85 dBm and the current background noise strength is-95 dBm, the SNR is 10 dB.

The RSSI value may be customized by a Wi Fi chip manufacturer in a proprietary manner. The RSSI value can range from 0 to a maximum value, such as 0 to 255, at the discretion of the manufacturer. Some manufacturers may publish the RSSI execution values on product documentation and websites for users to query. Where different vendors may choose different RSSI maximum values, for example, vendor a may choose RSSI values ranging from 0 to 100, while vendor B chooses RSSI values from 0 to 30, for example, when vendor a indicates that the current signal is 25, vendor B may express 8 for the same signal. The RSSI value is used for measuring the strength of the Wi Fi received signal, the unit corresponding to the RSSI value can be further represented by Decibel-milliwatts (dbm), and dbm represents the relative relation between a certain power and 1 mw. For example, manufacturer a may define the RSSI value to be in the range of 0-127, and when the RSSI is 80, the corresponding Wi Fi received signal strength is-65 dBm; for example, the B manufacturer may define that the RSSI value is in the range of 0 to 127, and when the RSSI is 80, the corresponding Wi Fi received signal strength is-60 dBm.

Wherein the Packet Error Rate (PER) value is used to indicate a probability of a packet transmission error occurring when a wireless channel transmits a data packet. Is an index for measuring the data transmission accuracy in a specified time.

The multi-path time delay value represents the time delay of the wireless signal reaching the receiving end after the wireless signal is propagated through multi-paths. For example, a wireless signal from a transmitting end may reach a receiving end through a direct path, or may reach the receiving end through a non-direct path due to transmission and diffraction, so as to form a multipath phenomenon. The number of signal reflections depends on the signal incidence angle, carrier frequency, polarization of the incident wave, etc. The direct path and various indirect reflected paths have different lengths, and therefore the time for signal components passing through different paths to reach the receiving end is different.

Step S102, determining a pre-adjustment rate according to the current state information of the multiple weight items of the first antenna and a first weighted value obtained by weighting the weight values.

The first antenna is an MIMO antenna, and weighting values corresponding to a signal-to-noise ratio value, a received signal strength index value, a packet error rate value and a multipath time delay value of the MIMO antenna are weighted to obtain a first weighting value. The weight value corresponding to each weight item can be preset with an initial weight value before leaving a factory, and as the use time goes on, the electronic equipment can collect historical state information corresponding to each weight item when the MIMO antenna actually adjusts the transmission rate in a historical time period so as to analyze the influence degree of each weight item on the transmission rate, and the weight value of each weight item is adjusted through reverse feedback according to the influence degree. After multiple feedback adjustments, the weight values of the weight items are finally converged, so that the first weight value can more accurately reflect the transmission performance of the MIMO antenna in the electronic equipment.

The Wi-Fi chip manufacturer can preset a rate control table before the Wi-Fi module leaves a factory, and the rate control table is used for storing a plurality of weighted value thresholds and preset rates corresponding to the weighted value thresholds. Determining a preset adjustment rate by matching the first weight value of the MIMO antenna with a plurality of weight value thresholds in the rate control table.

For example, a weight threshold is defined as a₁To a₈The rate control table shown in table 1 is set:

TABLE 1

In table 1, GI is Guard Interval (GI), when a Wi Fi module transmits a wireless signal, in order to ensure reliability of data transmission, a Guard Interval GI may be disposed between adjacent wireless signal data for ensuring that a receiving party can correctly decode the wireless signal, where ns is expressed as a nanosecond.

In which information symbols of a wireless signal are transmitted through multiple paths due to the influence of multipath effects, and may collide with each other, resulting in inter-symbol interference (ISI). For this purpose, the 802.11a/g standard of the wireless transmission standard protocol requires that when sending information symbols, a time interval GI of 800ns is guaranteed between the information symbols. The default of the wireless transmission standard protocol 802.11n is 800ns, when the influence of multipath effect is small, the Wi Fi module may also configure the time interval GI to 400ns, and taking a spatial stream as an example, may improve the throughput by approximately 10%, such as from 65Mbps to 72.2 Mbps. Due to the use of the guard interval GI, the information symbols of the wireless signal may be converted from a state of being originally subjected to intersymbol interference to a state of not being subjected to intersymbol interference.

Wherein each set of weighted value threshold corresponds to a set of pre-adjusted rates of different GI.

In some embodiments, the step S102 may be further implemented by:

(1) matching the first weighted value of the first antenna with a plurality of weighted value thresholds stored in a rate control table, wherein the rate control table stores a pre-adjusted rate corresponding to each weighted value threshold.

The first antenna is a MIMO antenna, and the first weighted value of the MIMO antenna is matched with a plurality of weighted value thresholds stored in a rate control table, wherein the rate control table stores a preset rate corresponding to each weighted value threshold.

For example, taking Table 1 as an example, 0 to a₁The first weight and value within the range is a₁The weighted value threshold values are matched; greater than a₁And is less than or equal to a₂The first weight and value within the range is a₂The weighted value threshold values are matched; greater than a₂And is less than or equal to a₃The first weight and value within the range is a₃The weighted value threshold values are matched; greater than a₃And is less than or equal to a₄The first weight and value within the range is a₄The weighted value threshold values are matched; greater than a₄And is less than or equal to a₅The first weight and value within the range is a₅The weighted value threshold values are matched; greater than a₅And is less than or equal to a₆The first weight and value within the range is a₆The weighted value threshold values are matched; greater than a₆And is less than or equal to a₇The first weight and value within the range is a₇The weighted value threshold values are matched; greater than a₇And is less than or equal to a₈The first weight and value within the range is a₈The weighted value thresholds of (a) match.

(2) And when the rate control table has a weighted value threshold matched with the first weighted value of the first antenna, selecting the pre-adjustment rate corresponding to the weighted value threshold matched with the first weighted value of the first antenna.

And when a weighted value threshold matched with the first weighted value of the MIMO antenna exists in the rate control table, selecting the pre-adjustment rate corresponding to the weighted value threshold matched with the first weighted value of the MIMO antenna.

For example, the first weight value of the MIMO antenna is a₄And a number is a₄If the weighted value thresholds are matched, a weighted value threshold matched with the first weighted value of the MIMO antenna exists in the rate control table, and a pre-adjustment rate corresponding to the weighted value threshold matched with the first weighted value of the MIMO antenna is selected according to a time interval GI currently set by the Wi Fi module, for example, when GI is 800ns, the corresponding pre-adjustment rate is 26 Mbps.

Step S103, when it is determined that the preset rates of the first antenna and the second antenna corresponding to the preset rate exist in the rate table corresponding to the modulation and coding strategy, current state information and weight values of a plurality of weight items of the second antenna are obtained.

The method comprises the steps that a first antenna is an MIMO antenna, a second antenna is a SISO antenna, and when the preset rates of the MIMO antenna and the SISO antenna corresponding to the preset rate are determined to exist in a rate table corresponding to a Modulation and Coding Scheme (MCS) at the same time, the current state information and the weight values of a plurality of weight items of the SISO antenna are obtained.

Wherein, a rate table corresponding to the modulation and coding strategy MCS is preset. For example, taking the wireless transmission standard protocol 802.11n as an example, as shown in table 2, table 2 lists an MCS corresponding rate table with a bandwidth of 20 megahertz (MHz).

TABLE 2

In table 2, BPSK is Binary Phase Shift Keying (BPSK), which is one of conversion methods for converting an analog signal into a data value, and represents a method for performing Phase Shift by information Keying by using a combination of a plurality of waves having a Phase offset. BPSK uses a reference sine wave and a phase-inverted wave, and allows 1-bit information to be transmitted and received simultaneously by setting one of them to 0 and the other to 1.

In table 2, QPSK is Quadrature Phase Shift Keying (QPSK), also called Quadrature Phase Shift Keying (QPSK), and QPSK uses four different Phase differences of a carrier to represent input digital information, which is Quaternary Phase Shift Keying (QPSK). In QPSK, 2 bits of information can be transmitted per modulation.

In table 2, QAM is Quadrature Amplitude Modulation (QAM), and QAM suppresses carrier double-sideband Amplitude Modulation on two mutually orthogonal co-frequency carriers by using two independent baseband signals, and realizes transmission of two parallel paths of digital information by using orthogonality of frequency spectrums of the modulated signals within the same bandwidth. The modulation scheme is generally binary QAM (4-QAM), quaternary QAM (l6-QAM), octal QAM (64-QAM), or the like.

Wherein the obtaining of the current state information and the weight values of the plurality of weight items of the second antenna includes:

and acquiring the signal-to-noise ratio value, the received signal strength index value, the packet error rate value and the multipath delay value of the second antenna, and acquiring weight values corresponding to the packet error rate value, the received signal strength index value, the signal-to-noise ratio value and the multipath delay value of the second antenna respectively.

In some embodiments, the step S103 may be further implemented by:

(1) and acquiring the index number of the modulation and coding strategy corresponding to the preset rate from the rate table corresponding to the modulation and coding strategy.

For example, the MCS index corresponding to the pre-adjusted rate is obtained from the MCS corresponding rate table.

For example, the pre-adjusted rate is 26Mbps, and MCS index numbers corresponding to the pre-adjusted rate are obtained from the MCS corresponding rate table as MCS3 and MCS 9.

(2) And acquiring the spatial stream corresponding to the modulation and coding strategy index number.

For example, the spatial stream corresponding to the MCS index is obtained, the spatial stream corresponding to the MCS index MCS3 is 1x1, and the spatial stream corresponding to the MCS index MCS9 is 2x 2.

(3) When the antenna mode corresponding to the spatial stream includes a first antenna and a second antenna at the same time, determining that preset rates of the first antenna and the second antenna corresponding to the preset rate exist in the rate table corresponding to the modulation and coding strategy at the same time, and then obtaining current state information and weighted values of a plurality of weighted items of the second antenna.

When the antenna mode corresponding to the spatial stream simultaneously comprises the MIMO antenna and the SISO antenna, determining that preset rates of the MIMO antenna and the SISO antenna corresponding to the preset rate exist in the MCS corresponding rate table, and acquiring current state information and weight values of a plurality of weight items of the SISO antenna.

For example, the pre-adjustment rate is 26Mbps, the MCS index numbers corresponding to the pre-adjustment rate are obtained from the MCS corresponding rate table as MCS3 and MCS9, the spatial stream with the MCS index number as MCS3 is 1x1, and the spatial stream with the MCS index number as MCS9 is 2x2, so the spatial streams with the MCS index numbers include 1x1 and 2x 2. The antenna mode corresponding to spatial stream 1x1 is a SISO antenna, and the antenna mode corresponding to spatial stream 2x2 is a MIMO antenna. Therefore, it is determined that the antenna mode corresponding to the spatial stream includes both MIMO antennas and SISO antennas, and thus the preset rates of the MIMO antennas and the SISO antennas corresponding to the preset rate are present in the MCS corresponding rate table at the same time, and then the current state information and the weight values of the multiple weight items of the SISO antennas are further obtained.

The MIMO antenna includes multiple antennas, and in the same electronic device, SISO antennas used by the WiFi module when entering the SISO mode may share an antenna of one of the MIMO antennas, or may be antennas of a single-hop link that is set independently. Current state information of a plurality of weight items of a certain antenna serving as a SISO antenna in a SISO mode and weight values are acquired.

Step S104, obtaining a second weighted value according to the current state information of the plurality of weighted items of the second antenna and the weighting of the weighted values.

And weighting weighted values corresponding to the signal-to-noise ratio value, the received signal strength index value, the packet error rate value and the multipath time delay value of the SISO antenna respectively to obtain a second weighted value. The electronic device may collect historical state information corresponding to each weight item when the transmission rate of the SISO antenna is actually adjusted in a historical period as service time goes on, so as to analyze the influence degree of each weight item on the transmission rate, and reversely feedback and adjust the weight value of each weight item according to the influence degree. After multiple feedback adjustments, the weighted values of the weighted items are finally converged, so that the second weighted value can more accurately reflect the transmission performance of the SISO antenna in the electronic equipment. The weight value corresponding to each weight item in the SISO antenna may be set to the same parameter as the weight value corresponding to the weight item of the MIMO antenna, or may be set to a different parameter.

Step S105, if the second weighted value is greater than the first weighted value, controlling the working antenna of the wifi module to switch from the first antenna to the second antenna, and adjusting the rate of transmitting the wireless signal to the pre-adjusted rate.

Wherein the first antenna is a MIMO antenna, the second antenna is a SISO antenna, and if the first weighted value of the SISO antenna is greater than the second weighted value of the MIMO antenna, the operating antenna of the WiFi module is controlled to switch from the MIMO antenna to the SISO antenna, and the rate of transmitting the wireless signal is adjusted to the pre-adjusted rate.

Wherein, if the first weighted value of the SISO antenna is greater than the second weighted value of the MIMO antenna and the transmission performance of the SISO antenna is better than that of the MIMO antenna, the operating antenna of the WiFi module is controlled to switch from the MIMO antenna to the SISO antenna and the rate of transmitting the wireless signal is adjusted to the pre-adjusted rate.

In some embodiments, the method further comprises:

if the second weighted value is equal to the first weighted value, setting priority levels of the weighted items, wherein the signal-to-noise ratio value, the received signal strength index value, the packet error rate value and the multipath time delay value correspond to first to fourth priority levels respectively;

and sequentially comparing the magnitude relation of the plurality of weight items of the second antenna with the plurality of weight items of the first antenna according to the priority, so as to adjust the working antenna of the wireless fidelity module and the rate of transmitting the wireless signals according to the magnitude relation.

In some embodiments, the sequentially comparing, according to the priority, magnitude relationships of the plurality of weight items of the second antenna with the plurality of weight items of the first antenna to adjust the working antenna of the wifi module and a rate of transmitting the wireless signal according to the magnitude relationships includes:

comparing the magnitude relation between the signal-to-noise ratio of the second antenna and the signal-to-noise ratio of the first antenna;

and if the signal-to-noise ratio of the second antenna is greater than the signal-to-noise ratio of the first antenna, controlling the working antenna of the wireless fidelity module to be switched from the first antenna to the second antenna, and adjusting the rate of transmitting the wireless signals to the pre-adjustment rate.

In some embodiments, after comparing the magnitude relationship between the signal-to-noise ratio value of the second antenna and the signal-to-noise ratio value of the first antenna, the method further includes:

if the signal-to-noise ratio of the second antenna is equal to the signal-to-noise ratio of the first antenna, comparing the magnitude relationship between the received signal strength index value of the second antenna and the received signal strength index value of the first antenna;

If the signal-to-noise ratio of the SISO antenna is equal to the signal-to-noise ratio of the MIMO antenna, which antenna cannot be accurately identified as having better transmission performance by using the signal-to-noise ratio as a measure, then step S2062 is further performed to better identify the transmission performance of the SISO antenna and the transmission performance of the MIMO antenna; if the signal-to-noise ratio of the SISO antenna is greater than the signal-to-noise ratio of the MIMO antenna, which indicates that the transmission performance of the SISO antenna is better than that of the MIMO antenna, then step S2067 is executed; if the signal-to-noise ratio of the SISO antenna is smaller than the signal-to-noise ratio of the MIMO antenna, which indicates that the transmission performance of the MIMO antenna is better than that of the SISO antenna, step S2068 is performed.

Wherein, if the signal-to-noise ratio of the SISO antenna is equal to the signal-to-noise ratio of the MIMO antenna, the magnitude relationship between the index value of the received signal strength of the SISO antenna and the index value of the received signal strength of the MIMO antenna is further compared. If the index of the strength of the received signal of the SISO antenna is equal to the index of the strength of the received signal of the MIMO antenna, which indicates that the transmission performance of which antenna is better cannot be accurately distinguished by using the signal-to-noise ratio and the index of the strength of the received signal as the metrics, then to better distinguish the transmission performance of the SISO antenna from the transmission performance of the MIMO antenna, step S2063 is further executed; if the index value of the received signal strength of the SISO antenna is greater than the index value of the received signal strength of the MIMO antenna, which indicates that the transmission performance of the SISO antenna is better than that of the MIMO antenna, then go to step S2067; if the index value of the received signal strength of the SISO antenna is smaller than the index value of the received signal strength of the MIMO antenna, which indicates that the transmission performance of the MIMO antenna is better than that of the SISO antenna, step S2068 is executed.

And if the received signal strength index value of the SISO antenna is equal to the received signal strength index value of the MIMO antenna, further comparing the size relationship between the packet error rate value of the SISO antenna and the packet error rate value of the MIMO antenna. If the packet error rate of the SISO antenna is equal to the packet error rate of the MIMO antenna, which indicates that the transmission performance of which antenna cannot be accurately identified as being better by using the signal-to-noise ratio, the received signal strength index value, and the packet error rate as the metrics, then step S2064 is further performed to better identify the transmission performance of the SISO antenna and the transmission performance of the MIMO antenna; if the packet error rate value of the SISO antenna is smaller than the packet error rate value of the MIMO antenna, which indicates that the transmission performance of the SISO antenna is better than that of the MIMO antenna, then step S2067 is executed; if the packet error rate of the SISO antenna is greater than the packet error rate of the MIMO antenna, which indicates that the transmission performance of the MIMO antenna is better than that of the SISO antenna, step S2068 is performed.

And if the packet error rate value of the SISO antenna is equal to the packet error rate value of the MIMO antenna, further comparing the size relationship between the multipath delay value of the SISO antenna and the multipath delay value of the MIMO antenna. If the multi-path delay value of the SISO antenna is equal to the multi-path delay value of the MIMO antenna, which indicates that the transmission performance of the SISO antenna is similar to that of the MIMO antenna, then step S2065 is further performed; if the multi-path delay value of the SISO antenna is smaller than that of the MIMO antenna, which indicates that the transmission performance of the SISO antenna is better than that of the MIMO antenna, then step S2067 is executed; if the multi-path delay value of the SISO antenna is greater than the multi-path delay value of the MIMO antenna, which indicates that the transmission performance of the MIMO antenna is better than that of the SISO antenna, step S2068 is performed.

Step S2066, determining whether the battery power of the electronic device is less than the power threshold. If yes, go to step S2067; if not, step S2068 is executed.

In the same speed and the same time period, the electric quantity consumed by the WiFi module for transmitting the wireless signals through the MIMO antenna is larger than the electric quantity consumed by the WiFi module for transmitting the wireless signals through the SISO antenna. If the battery power of the electronic device is less than the power threshold, for example, less than 30%, in order to ensure the endurance time of the electronic device, step S2067 is executed to control the operating antenna of the WiFi module to switch from the MIMO antenna to the SISO antenna, and adjust the rate of transmitting the wireless signal to the pre-adjusted rate. If the battery power of the electronic device is not less than the power threshold, step S2068 is executed to continue controlling the working antenna of the WiFi module to remain at the MIMO antenna, so that the rate of transmitting the wireless signal can be adjusted to the pre-adjustment rate.

Step S2067, controlling the working antenna of the wireless fidelity module to switch from the first antenna to the second antenna, and adjusting the rate of transmitting the wireless signal to the pre-adjusted rate.

And if the signal-to-noise ratio value of the SISO antenna is greater than that of the MIMO antenna, controlling the working antenna of the WiFi module to be switched from the MIMO antenna to the SISO antenna, and adjusting the rate of transmitting the wireless signal to the pre-adjustment rate.

Wherein when the signal-to-noise ratio of the SISO antenna is equal to the signal-to-noise ratio of the MIMO antenna, if the received signal strength index value of the SISO antenna is greater than the received signal strength index value of the MIMO antenna, the working antenna of the WiFi module is controlled to be switched from the MIMO antenna to the SISO antenna, and the rate of transmitting the wireless signal is adjusted to the pre-adjustment rate.

When the signal-to-noise ratio and the received signal strength index value of the SISO antenna are respectively equal to the signal-to-noise ratio and the received signal strength index value of the MIMO antenna, if the packet error rate value of the SISO antenna is smaller than the packet error rate value of the MIMO antenna, the working antenna of the WiFi module is controlled to be switched from the MIMO antenna to the SISO antenna, and the rate of transmitting the wireless signal is adjusted to the pre-adjustment rate.

When the signal-to-noise ratio value, the received signal strength index value and the packet error rate value of the SISO antenna are respectively equal to the signal-to-noise ratio value, the received signal strength index value and the packet error rate value of the MIMO antenna, if the multipath delay value of the SISO antenna is smaller than the multipath delay value of the MIMO antenna, the working antenna of the WiFi module is controlled to be switched from the MIMO antenna to the SISO antenna, and the rate of transmitting the wireless signal is adjusted to the pre-adjustment rate.

When the signal-to-noise ratio value, the received signal strength index value, the packet error rate value and the multipath delay value of the SISO antenna are respectively equal to the signal-to-noise ratio value, the received signal strength index value, the packet error rate value and the multipath delay value of the MIMO antenna, if the battery power of the electronic equipment is smaller than the power threshold, the working antenna of the WiFi module is controlled to be switched from the MIMO antenna to the SISO antenna, and the rate of transmitting the wireless signal is adjusted to the pre-adjustment rate.

Step S2068, controlling the working antenna of the wireless fidelity module to maintain at the first antenna, and adjusting the rate of transmitting the wireless signal to the pre-adjusted rate.

In the embodiment of the present application, when a wireless fidelity module transmits a wireless signal through a first antenna, current state information and weight values of a plurality of weight items of the first antenna are obtained and weighted to obtain a first weight value, a pre-adjustment rate is determined, when it is determined that a preset rate of the first antenna and a preset rate of a second antenna corresponding to the pre-adjustment rate exist in a rate table corresponding to a modulation and coding strategy, current state information and weight values of a plurality of weight items of the second antenna are obtained and weighted to obtain a second weight value, and if the second weight value is greater than the first weight value, a working antenna of the wireless fidelity module is controlled to be switched from the first antenna to the second antenna, and a rate of transmitting the wireless signal is adjusted to the pre-adjustment rate. According to the embodiment of the application, the weighted values of the weighted items are used as the measurement indexes for switching the WiFi module between the MIMO antenna and the SISO antenna, so that the electronic equipment can more accurately switch the antennas between the MIMO mode and the SISO mode, the better performance of the antennas is exerted, and the network performance of the WiFi module is further improved.
