Description

Method and device for controlling receiving antenna

Technical field

This application relates to the field of terminals, and in particular to a method for controlling a receiving antenna, a terminal device, a computer-readable storage medium, and a computer program product.

Background technique

Multiple-input multiple-output (MIMO) technology refers to the use of multiple transmitting antennas and multiple receiving antennas at the transmitting end and the receiving end, respectively, so that the signal is sent and received through multiple antennas at the transmitting end and the receiving end. The terminal combines the signals received by multiple receiving antennas to obtain diversity gain and array gain. MIMO technology can make full use of space resources and achieve multiple transmissions and multiple receptions through multiple antennas. Without increasing spectrum resources and antenna transmission power, it can double the system channel capacity, showing obvious advantages, and is regarded as the next generation. The core technology of mobile communication.

In order to improve the signal quality of the combined signal of the multiple receiving antennas of the multi-antenna terminal equipment, the prior art uses a band-pass filter to filter the interference signals outside the filter bandwidth, but this method cannot eliminate the interference signals within the filter bandwidth. Perform filtering. For this reason, the prior art introduces interference cancellation technology after the bandpass filter to eliminate the interference signal within the filter bandwidth. However, when some of the multiple receiving antennas receive relatively stronger interference signals, the signal quality of different receiving antennas is poorly balanced. At this time, it is difficult for the multi-antenna terminal equipment to achieve better interference cancellation effects.

In order to increase the effective utilization of radiated power, more and more radio transmitters use directional transmission to transmit signals, which leads to the interference signals received by multi-antenna terminal equipment with better directivity. Some of the multiple receiving antennas will receive relatively stronger interference signals, which makes it difficult for multi-antenna terminal equipment to effectively improve the signal quality of the combined signal by using the interference cancellation effect.

It should be understood that the terms used in this way can be interchanged under appropriate circumstances, and this is merely a way of distinguishing objects with the same attributes in the description of the embodiments of the present application.

In order to increase the effective utilization of radiated power, more and more radio transmitters use directional transmission to transmit signals. Therefore, the interference signals received by multi-antenna terminal equipment will be more directional. Part of the receiving antennas in the receiving antenna will receive relatively stronger interference signals, which makes it difficult for multi-antenna terminal equipment to effectively improve the signal quality of the combined signal by using the interference cancellation effect.

In order to improve the signal quality of the combined signal of multiple receiving antennas under strong interference from a certain direction, the present application provides a method for controlling the receiving antenna, which is applied to a terminal device, and the terminal device includes multiple receiving antennas. The terminal device mentioned in this application can be any terminal device with radio transceiver function, such as user equipment (UE), mobile terminal or wireless terminal, mobile phone, computer such as laptop computer, personal digital assistant Or tablet computers, customer premise equipment (CPE), etc. Among them, wireless CPE is a wireless terminal access device that receives WiFi signals, which can replace wireless client devices such as wireless network cards, and can receive wireless signals from wireless routers, wireless APs, and wireless base stations. It is a new type of wireless terminal access. Into the device. At the same time, wireless CPE is also a device that converts high-speed 4G or 5G signals into WiFi signals, which can be widely used in rural areas, towns, hospitals, units, factories, communities and other wireless network access, which is helpful to save the laying of wired networks. cost.

Referring to FIG. 1, an embodiment of the method for controlling a receiving antenna of the present application includes the following steps:

100. Obtain the signal quality of the receiving antenna in the open state among the multiple receiving antennas;

For a multi-antenna terminal device, it generally has multiple antennas that can be used to receive signals. In this application, the antenna that can be used to receive signals among the multiple antennas of the terminal device is called a receiving antenna. Different receiving antennas usually have different directions of transmitting signals or receiving signals. The terminal device can control the receiving direction of each receiving antenna, or control the on-off state (on or off) of each receiving antenna, or control the receiving direction and on-off state of each receiving antenna, and use multiple receiving antennas that are on The state of the receiving antenna receives the signal, and combines the received signals to obtain a combined signal to obtain diversity gain and array gain.

200. Control the receiving directions or switch states of multiple receiving antennas according to the acquired signal quality;

The terminal device can control the receiving direction or switching state of multiple receiving antennas according to the acquired signal quality to optimize the signal quality of the combined signal of the multiple receiving antennas. The received signal can be controlled by controlling the receiving direction of each of the multiple receiving antennas, or by controlling the switch state of each antenna of the multiple receiving antennas, or by controlling the receiving direction and switch state of each antenna of the multiple receiving antennas In other words, you can choose which direction signals to receive and which directions to not receive. Since the signal quality of the signal received by the receiving antenna (referred to as the signal quality of the receiving antenna) can reflect the strength of the interference signal, and the interference signal generally has strong directivity, it can be determined according to the signal quality of the receiving antenna in the open state The direction of the interference signal, in turn, controls the receiving direction and/or the switch state of each receiving antenna in the multiple receiving antennas, which is beneficial to reduce the received interference signal, thereby optimizing the signal quality of the combined signal of the multiple receiving antennas.

The signal quality mentioned in this application, for example, may be Signal to Interference Noise Ratio (SINR), Reference Signal Received Power (RSRP), and Received Signal Strength Indicator (Received) Signal Strength Indicator, RSSI) and Reference Signal Received Quality (RSRQ).

Regarding controlling the receiving direction of multiple receiving antennas, optionally, the terminal device can control the receiving direction of the receiving antenna by adjusting the direction of a single receiving antenna relative to the body, or, optionally, the terminal device can adjust the receiving antenna The overall direction relative to the fuselage or the orientation of the terminal device is adjusted to control the receiving direction of the receiving antenna. For example, for a wireless CPE fixed on the outer wall of a house, the wireless CPE can be fixed on the outer wall of the house through a rotatable base. The wireless CPE can control the base to rotate a certain angle according to the signal quality of the receiving antenna to adjust the direction of the receiving antenna.

In a possible implementation manner, referring to FIG. 2, in step 200, the terminal device controlling the switching states of multiple receiving antennas according to the signal quality of the multiple receiving antennas may specifically include the following steps:

201. Determine a target receiving antenna from receiving antennas that are in an on state according to the acquired signal quality;

After the terminal device obtains the signal quality of the receiving antenna in the open state among the multiple receiving antennas, it can select a part of the receiving antenna from the receiving antennas in the open state among the multiple receiving antennas according to the acquired signal quality, and the selected part The receiving antenna, compared with other receiving antennas in the open state, receives stronger interference signals. For ease of description, the selected receiving antenna is called the target receiving antenna, that is, the interference signal received by the target receiving antenna is strong Interference signals received by other receiving antennas among the receiving antennas that are turned on.

202. Turn off the target receiving antenna.

After the terminal device determines the target receiving antenna, it can turn off the target receiving antenna to be in a closed state. It should be noted that the receiving antenna in the closed state only indicates that the antenna is temporarily not used for receiving signals, but, optionally, the antenna can be used for transmitting signals.

Exemplarily, referring to FIG. 3, another embodiment of the method for controlling a receiving antenna of the present application may include the following steps:

100a. Obtain the signal quality of the receiving antenna in the open state among the multiple receiving antennas;

201a. Determine a target receiving antenna from the receiving antennas that are in an on state according to the acquired signal quality;

202a. Turn off the target receiving antenna.

For each step in the embodiment corresponding to FIG. 3, reference may be made to the description of the foregoing corresponding step, which will not be repeated here. For example, the aforementioned corresponding step of step 100a is step 100.

In a possible implementation, it can be considered that the antenna with the worse signal quality, the stronger the interference signal it receives. Therefore, the target receiving antenna can be compared with other receiving antennas that are in the open state. The worse receiving antenna, in other words, the signal quality of the target receiving antenna is inferior to other receiving antennas that are in the on state. Exemplarily, two methods for determining the target receiving antenna are provided below:

Method 1. Step 201 may specifically include:

2011a. Calculate the combined signal quality of the receiving antenna that is turned on;

After the terminal device obtains the signal quality of each receiving antenna in the open state, it can use multiple methods to calculate the combined signal quality of the receiving antenna in the open state to simulate the terminal device combining the signals received by the receiving antenna in the open state For the signal quality of the subsequent combined signal, for example, the terminal device may calculate the average value of the signal quality of each receiving antenna in the on state as the combined signal quality of the receiving antenna in the on state.

2012a. Determine the receiving antenna whose signal quality is inferior to the combined signal quality.

After the terminal device calculates the combined signal quality, it can determine the receiving antenna whose signal quality is worse than the combined signal quality as the target receiving antenna.

Method 2: Step 201 may specifically include:

2011b. Sort the receiving antennas in the on state according to their signal quality;

Specifically, each receiving antenna may be sorted in ascending order or in descending order according to the quality of the signal.

2012b. Select one or more receiving antennas with relatively worst signal quality from the sorted receiving antennas.

The relatively worst multiple receiving antennas among the receiving antennas in the open state means that the signal quality of any selected receiving antenna is inferior to that of the unselected receiving antenna, that is, only some receiving antennas are selected from them As the target receiving antenna. Since the number of receiving antennas in the open state may change, in order to ensure that after the target receiving antenna is selected, there are still receiving antennas in the open state. Therefore, the target receiving antenna can be preset to occupy the receiving antenna in the open state. The ratio, such as 30%, determines the designated number of target receiving antennas according to a preset ratio, and then selects the designated number of receiving antennas with the worst signal quality from the sorted receiving antennas.

In some embodiments of the present application, after step 100 and before step 201, the method for controlling the receiving antenna of the present application may further include the following steps:

300. Determine whether the combined signal quality of the receiving antenna in the on state is inferior to the signal quality threshold according to the acquired signal quality, if it is inferior to the signal quality threshold, perform step 201, and if it is superior to the signal quality threshold, perform other operations;

After the terminal device obtains the signal quality of the receiving antenna in the open state among the multiple receiving antennas, it can calculate the combined signal quality of the receiving antenna in the open state, which may refer to the foregoing step 2011a, which is not repeated here. The terminal device can determine whether the combined signal quality of the receiving antenna in the on state is inferior to the signal quality threshold. If the combined signal quality of the receiving antenna in the on state is inferior to the signal quality threshold, step 201 is executed, if the receiving antenna in the on state is If the combined signal quality is higher, perform other operations than step 201, for example, perform step 100 again. If the combined signal quality of the receiving antenna in the turned-on state is equal to the signal quality threshold, the terminal device may be designed to perform step 201, or may be designed to perform other operations, and the steps selected in the case of being equal are not specifically limited here.

Exemplarily, referring to FIG. 4, another embodiment of the method for controlling a receiving antenna of the present application may include the following steps:

100b. Acquire the signal quality of the receiving antenna in the open state among the multiple receiving antennas;

300b. Determine whether the combined signal quality is inferior to the signal quality threshold, if it is inferior to the signal quality threshold, execute step 201a, and if it is not inferior to the signal quality threshold, execute step 100b;

201b. Determine the target receiving antenna from the receiving antennas in the turned-on state according to the acquired signal quality;

202b. Turn off the target receiving antenna.

For each step in the embodiment corresponding to FIG. 4, reference may be made to the description of the foregoing corresponding step, which will not be repeated here. For example, the aforementioned corresponding step of step 100b is step 100.

The interference signal in a certain direction generally lasts for a period of time. However, with the passage of time, the direction of the interference signal relative to the terminal device may change, or the interference signal may weaken or even disappear, or, in the interference signal At the same time, the terminal equipment will be subject to new interference from other directions. In order to enable the method for controlling the receiving antenna provided in this application to adapt to the variability of the interference signal, and to effectively improve the signal quality of the combined signal for a long time, it is possible In the implementation manner, any one of the foregoing embodiments of the method for controlling a receiving antenna may be regarded as a single cycle, and the terminal device may repeatedly execute any of the foregoing embodiments of the method for controlling a receiving antenna. Exemplarily, in some embodiments of the present application, the terminal device may repeatedly execute the embodiment corresponding to FIG. 2, that is, the embodiment corresponding to FIG. 2 is used as a single cycle, and the terminal device may enter the next time after performing step 202a. Loop and execute step 100a again.

The terminal device can immediately enter the next cycle after completing a single cycle (such as 100a-201a-202a) of the control method of the receiving antenna, that is, execute step 100a immediately, or it can execute step again after a period of time. 100a. Alternatively, step 100a may be executed again when the loop trigger condition is met.

In some embodiments of the present application, after step 202, the method for controlling the receiving antenna of the present application may further include the following steps:

400. Determine whether the loop trigger condition is met, if the loop trigger condition is met, then execute step 100, and if the loop trigger condition is not met, execute step 500;

In a possible implementation manner, the loop trigger condition may be that the number of receiving antennas in the open state among the multiple receiving antennas is greater than the number threshold, or, in a possible implementation manner, the loop trigger condition may be the terminal device's The downlink data transmission rate is higher than the transmission rate threshold, or, in a possible implementation, the cycle trigger condition may be that the number of receiving antennas in the on state among the multiple receiving antennas is greater than the number threshold, and the downlink data transmission of the terminal device The rate is higher than the transmission rate threshold.

500. Perform other operations;

If the terminal device determines that the loop trigger condition is not met, other operations other than step 100 may be performed, for example, step 400 is performed again after waiting for a preset time.

Exemplarily, referring to FIG. 5, another embodiment of the method for controlling a receiving antenna of the present application may include the following steps:

100c. Obtain the signal quality of the receiving antenna in the open state among the multiple receiving antennas;

201c. Determine a target receiving antenna from the receiving antennas in the turned-on state according to the acquired signal quality;

202c. Turn off the target receiving antenna;

400c. Determine whether the number of receiving antennas in the ON state is greater than the number threshold, if it is greater than the number threshold, perform step 100c, and if it is not greater than the number threshold, perform step 400c again.

For each step in the embodiment corresponding to FIG. 5, reference may be made to the description of the foregoing corresponding step, which will not be repeated here. For example, the aforementioned corresponding step of step 100c is step 100.

In a possible implementation manner of this application, step 500 may specifically include the following steps:

501. Turn on all of the multiple receiving antennas;

In step 400, if the terminal device determines that the loop trigger condition is not met, the terminal device can turn on all of the multiple receiving antennas, and use all antennas available for receiving signals to receive signals. Afterwards, in a possible implementation manner, the terminal device may perform step 400 again, or, in a possible implementation manner, the terminal device may perform step 100.

Exemplarily, referring to FIG. 6, another embodiment of the method for controlling a receiving antenna of the present application may include the following steps:

100d. Obtain the signal quality of the receiving antenna in the open state among the multiple receiving antennas;

201d. Determine the target receiving antenna from the receiving antennas in the turned-on state according to the acquired signal quality;

202d. Turn off the target receiving antenna;

400d. Determine whether the downlink data transmission rate of the terminal device is higher than the transmission rate threshold, if it is higher than the transmission rate threshold, perform step 100d, and if it is not higher than the transmission rate threshold, perform step 501d;

501d. Turn on all of the multiple receiving antennas, and trigger step 400d.

For each step in the embodiment corresponding to FIG. 6, reference may be made to the description of the foregoing corresponding step, which will not be repeated here. For example, the aforementioned corresponding step of step 100d is step 100.

In some embodiments, after step 202, the embodiment of the present application may further include the following steps:

600. If the closing time of the target receiving antenna exceeds the duration threshold, turn on the target receiving antenna;

After turning off the target receiving antenna, the terminal device may start a timer, and when the duration of the timer exceeds the duration threshold, the terminal device may turn on the target receiving antenna corresponding to the timer. Illustratively, suppose that the receiving antennas of the terminal device in the on state include antenna 1, antenna 2, antenna 3, and antenna 4. After the first cycle is executed, the terminal device turns off antenna 1 and turns on timer 1. After the second cycle, the terminal device turns off antenna 2 and turns on timer 2. When the time recorded by timer 1 exceeds the duration threshold, the terminal device can turn on antenna 1.

In a possible implementation manner, the duration threshold may be a preset fixed duration, and optionally, the duration thresholds corresponding to each receiving antenna may be the same. Or, in a possible implementation manner, the duration threshold may be a changeable duration calculated according to a preset algorithm. Optionally, the duration threshold corresponding to different receiving antennas may be different. For example, the duration threshold may be It is positively correlated with the number of historical closures of the target receiving antenna. In some embodiments, the embodiments of the present application may further include the following steps:

700. Determine the duration threshold according to the historical number of closed times of the target receiving antenna;

After the terminal device determines the target receiving antenna, the duration threshold may be determined according to the historical number of times the target receiving antenna is closed, and the duration threshold is positively correlated with the historical number of times the target receiving antenna is closed. Exemplarily, the duration threshold of the target receiving antenna=N×T, where N is the number of historical shutdowns of the target receiving antenna, and T is the preset fixed duration. Assuming T is 1 minute, the number of historical shutdowns of the receiving antenna 1 is 1 , The number of historical shutdowns of antenna 2 is 5, and when the terminal device performs the current cycle, the determined target antenna includes antenna 1 and antenna 2, then the terminal device can determine that the duration threshold of receiving antenna 1 is 1 minute, and the duration threshold of antenna 2 For 5 minutes. The receiving antenna with the more historical closing times is likely to correspond to the longer duration of the interference signal. By setting the duration threshold to be positively correlated with the historical closing times of the target receiving antenna, it is beneficial to extend the closing time of the receiving antenna. It is beneficial to reduce the interference signal received by the receiving antenna, thereby improving the signal quality of the combined signal of the multiple receiving antennas.

Exemplarily, referring to FIG. 7, another embodiment of the method for controlling a receiving antenna of the present application may include the following steps:

100e. Obtain the signal quality of the receiving antenna in the open state among the multiple receiving antennas;

201e: Determine a target receiving antenna from the receiving antennas in the turned-on state according to the acquired signal quality;

202e. Turn off the target receiving antenna;

600e. If the off duration of the target receiving antenna exceeds the duration threshold, turn on the target receiving antenna;

400e. After step 202e, determine whether the downlink data transmission rate of the terminal device is higher than the transmission rate threshold. If it is higher than the transmission rate threshold, perform step 100e; if it is not higher than the transmission rate threshold, trigger step 400e.

For each step in the embodiment corresponding to FIG. 7, reference may be made to the description of the foregoing corresponding step, which will not be repeated here. For example, the aforementioned corresponding step of step 100e is step 100.
