The technical solutions in the embodiments of the present application are clearly and completely described in the following with reference to the drawings in the embodiments of the present application. It is obvious that the described embodiments are only a part of the embodiments of the present application, and not all of the embodiments. All other embodiments obtained by a person of ordinary skill in the art based on the embodiments of the present application without departing from the inventive scope are the scope of the present application.

Example 1:

S101: When performing data transmission, determining, according to the strength of the current receiving end signal and the preset signal strength threshold, and the first number of antennas currently used by the mobile terminal for data transmission, determining the target of the antenna for performing data transmission by the mobile terminal Quantity.

S102: The mobile terminal uses the target number of antennas to perform data transmission.

The data transmission method provided by the embodiment of the present application is applied to a mobile terminal, hereinafter referred to as a terminal.

The terminal can perform data transmission with other devices, such as a base station, a router, and the like.

In the process of data transmission, the terminal can determine the strength of the signal received by the receiving end. The receiving end is one end of receiving data during the process of data transmission. If the terminal is the receiving end, the other device is the transmitting end, and the terminal will recognize the strength of the received signal as the strength of the receiving signal at the receiving end.

If the terminal is the transmitting end, the other device is the receiving end, and the terminal needs to determine the strength of the signal received by the other device. The terminal can receive other devices as the receiving end, and send the strength of the received signal of the other device to the terminal, because the data transmission process is very The terminal is the transmitting end at this moment, and the terminal becomes the receiving end at the next moment. Therefore, when the terminal is used as the transmitting end, the terminal can also use the strength of the received signal as the strength of the receiving signal at the receiving end. The process of obtaining the strength of the received signal by the terminal is a prior art, and is not described in the embodiment of the present application.

The terminal has a signal strength threshold and a first number of antennas currently performing data transmission. When the terminal performs data transmission, the terminal compares the obtained received signal strength of the receiving end with a preset signal strength threshold, and determines according to the comparison result. Whether to adjust the first quantity currently saved and how to adjust to determine the target number of antennas for data transmission. The signal strength threshold is the strength of the corresponding received signal when the communication quality can be guaranteed.

Specifically, if the strength of the received signal at the current receiving end is greater than the preset signal strength threshold, the first quantity is reduced, and the adjusted number of antennas is reduced as the target quantity; if the current receiving end receives If the strength of the signal is less than the preset signal strength threshold, the first quantity is increased and adjusted, and the adjusted number of antennas is increased as the target quantity; if the strength of the current receiving end signal is equal to the preset signal strength threshold , the first quantity is taken as the target quantity. It can be adjusted according to the set step size. When increasing or decreasing the adjustment, the step size of the setting is increased or decreased each time.

After the terminal determines the target number of antennas for data transmission, the terminal can use the target number of antennas for data transmission. Specifically, if the terminal is the receiving end, the target number of antennas are used for data reception, that is, the number of receiving antennas is the target number, and if the terminal is the transmitting end, the target number of antennas are used for data transmission, that is, the transmitting antenna The number is the target quantity.

In the embodiment of the present application, the mobile terminal may determine the target number of antennas for data transmission according to the strength of the received signal at the receiving end and the preset signal strength threshold. Under the premise of ensuring communication quality, the number of antennas can be flexibly adjusted, and the adjusted target number of antennas can be used for data transmission, which can achieve the effect of ensuring communication quality and reducing power consumption to a certain extent. .

Example 2:

In order to improve the accuracy of the target number of the determined antennas, in the embodiment of the present application, the strength of the received signal according to the current receiving end and the preset signal strength threshold, and the current terminal of the mobile terminal are saved.

If the strength of the current receiving signal received by the receiving end is equal to the preset signal strength threshold, the first quantity may be increased and adjusted. However, in order to reduce the number of adjustments, the first quantity may not be adjusted, and the first quantity is determined as the target quantity.

The first adjustment step and the second adjustment step may be the same or different. In order to improve the accuracy of the determined target number, the first adjustment step and the second adjustment step may both be 1.

If the terminal is the receiving end, the data transmission rate is the downlink data transmission rate, and the connection rate is the downlink connection rate. If the terminal is the sender, the data transmission rate is the uplink data transmission rate, and the connection rate is the uplink connection rate. In the case of external factors such as distance and constant, the more the number of antennas transmitting data, the higher the connection rate between the receiving end and the transmitting end in MIMO mode. In order to ensure the communication quality, the connection rate should satisfy the data transmission rate. That is, the connection rate should be no less than the data transmission rate. The process of determining the current data transmission rate and the connection rate by the terminal is a prior art, and is not described in the embodiment of the present application.

The terminal has a signal strength threshold and a first number of antennas currently performing data transmission. When the terminal performs data transmission, the terminal can determine the current data transmission rate and the connection rate, and the terminal obtains the strength of the received signal at the receiving end and the pre-determination. The signal strength thresholds are compared, and the data transmission rate is compared with the connection rate. According to the two comparison results, it is determined whether the current saved first quantity is adjusted, and how to adjust, thereby determining the target number of antennas for data transmission. .

Specifically, it may be determined whether the strength of the received signal at the current receiving end is greater than a preset signal strength threshold, and whether the connection rate is greater than a data transmission rate; if both are, the first quantity is reduced and adjusted, and the adjustment is reduced. The number of antennas afterwards is taken as the target number; if they are all, the first quantity is increased and adjusted, and the number of adjusted antennas is increased as the target quantity; if the current receiving end is equal to the preset strength The signal strength threshold, and the connection rate is equal to the data transmission rate, then the first number is taken as the target number.

If one and only one is greater than, the other is not greater than, that is, the strength of the received signal at the current receiving end is greater than the preset signal strength threshold, the connection rate is not greater than the data transmission rate, or the strength of the current receiving signal is not greater than the preset. The signal strength threshold, the connection rate is greater than the data transmission rate, the first quantity can be increased and adjusted, and the adjusted number of antennas is increased as the target quantity.

It can be adjusted according to the set step size. When increasing or decreasing the adjustment, the step size of the setting is increased or decreased each time. Of course, each time the adjustment is increased or decreased. The steps can be the same or different.

Example 4:

In order to improve the accuracy of the target number of the determined antennas, based on the foregoing embodiments, in the embodiment of the present application, the strength of the received signal according to the current receiving end, the preset signal strength threshold, the receiving end, and the sending The connection rate in the MIMO mode, the data transmission rate of the mobile terminal, and the first number of antennas currently being stored by the mobile terminal for data transmission, and determining the target number of antennas for data transmission by the mobile terminal include:

In the embodiment of the present application, the terminal adjusts the corresponding adjustment step size for the reduction adjustment and the increase adjustment, and specifically stores the third adjustment step length and the fourth adjustment step length respectively, and saves the third adjustment step length. The corresponding adjustment mode is to reduce the adjustment, and the adjustment mode corresponding to the fourth adjustment step is to increase the adjustment.

The terminal determines whether the strength of the received signal at the current receiving end is greater than a preset signal strength threshold, and the connection rate is greater than the data transmission rate; if yes, the preset third adjustment step size is used to reduce the first quantity. The fourth number of antennas obtained after the adjustment is reduced as the target number of antennas for data transmission, that is, the difference between the first quantity and the third adjustment step is used as the target quantity; if none, the preset fourth is adopted. Adjusting the step size, increasing the adjustment of the first quantity, increasing the fifth number of antennas obtained after the adjustment as the target number of antennas for data transmission, that is, the sum of the first quantity and the fourth adjustment step is targeted Quantity.

If the strength of the received signal at the current receiving end is equal to the preset signal strength threshold, and the connection rate is equal to the data transmission rate, at this time, the currently saved first quantity may be increased and adjusted. In order to reduce the number of adjustments, the first quantity may not be adjusted, and the first quantity is determined as the target quantity.

If it is judged whether the strength of the received signal at the current receiving end is greater than a preset signal strength threshold, and whether the connection rate is greater than the data transmission rate; if there is one and only one, in order to reduce the number of adjustments, the first quantity may not be increased. A big adjustment, the first quantity is the target quantity. That is, when the intensity is greater than the preset signal strength threshold, but the connection rate is not greater than the data transmission rate, or when the strength is not greater than the preset signal strength threshold, and the connection rate is greater than the data transmission rate, the first quantity is not adjusted, that is, the first A quantity as the target quantity.

If it is judged whether the strength of the received signal at the current receiving end is greater than a preset signal strength threshold, and whether the connection rate is greater than the data transmission rate; when at least one is no, in order to ensure the communication quality, the first quantity may also be increased.

The adjustment mode of the last number of antennas is saved in the terminal, that is, the adjustment method when the number of antennas is adjusted last time. If it is determined at this time, the first quantity saved is adjusted, that is, the current number of antennas cannot be adjusted. To meet the communication quality, in order to ensure the communication quality, no matter what the last adjustment method is, the first quantity needs to be adjusted and adjusted. Determining the current saved first quantity to perform an increase adjustment may be performed when determining that the strength of the received signal at the receiving end is less than a preset signal strength threshold, or determining that the strength of the received signal at the receiving end is less than a preset The signal strength threshold, and the connection rate is determined to be an increase adjustment when the data rate is less than the data transmission rate.

If it is determined that the current saved first quantity is to be reduced, it is determined whether the current adjustment method of the last number of antennas is an increase adjustment. If the adjustment is not increased, the subsequent step, that is, moving The first number of antennas currently being transmitted by the terminal for data transmission is reduced. Among them, the adjustment is not increased, one may be to reduce the adjustment, and the other may be that there is no adjustment mode, then the adjustment at this time is the first adjustment of the terminal. Determining the currently saved first quantity to perform the reduction adjustment may be performed when determining that the strength of the received signal at the receiving end is greater than a preset signal strength threshold, or determining that the strength of the received signal at the receiving end is greater than a preset The signal strength threshold is determined, and the connection adjustment is determined to be reduced when the connection rate is greater than the data transmission rate.

If the method for adjusting the number of the last saved antennas is to increase the adjustment, the method further includes: using the currently saved first quantity as the target number of antennas for data transmission by the mobile terminal. If the last adjustment mode is to increase the adjustment, and the judgment result at this time is to decrease the adjustment, it indicates that the communication quality corresponding to the first saved quantity is better, that is, the strength of the received signal at the receiving end is greater than the preset signal strength. The threshold, or the strength of the received signal at the receiving end is greater than the preset signal strength threshold, and the data transmission rate is greater than the connection rate. However, the communication quality before the previous increase adjustment is poor. If the reduction adjustment is continued, the communication quality may be poor. In order to ensure the communication quality, the first quantity saved may be kept unchanged. The first number currently saved is taken as the target number of antennas for data transmission.
