Description
Technical Field
The present 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
The multiple-input multiple-output (MIMO) technique is to use multiple transmitting antennas and multiple receiving antennas at a transmitting end and a receiving end, respectively, so that signals are transmitted and received through the multiple antennas at the transmitting end and the receiving end, and the receiving end combines the signals received by the multiple receiving antennas to obtain diversity gain and array gain. The MIMO technology can make full use of space resources, realize multiple transmission and multiple reception through multiple antennas, and improve system channel capacity by multiple times without increasing spectrum resources and antenna transmission power, shows significant advantages, and is considered as a core technology of next-generation mobile communication.
In order to improve the signal quality of the combined signal of multiple receiving antennas of the multi-antenna terminal device, the prior art uses a band-pass filter to filter the interference signal outside the filter bandwidth, but this method cannot filter the interference signal inside the filter bandwidth. For this reason, the prior art introduces an interference cancellation technique after the band-pass filter, so as to cancel the interference signal within the bandwidth of the filter. However, when some of the multiple receiving antennas receive relatively stronger interference signals, the signal quality of different receiving antennas is poorly balanced, and it is difficult for the multi-antenna terminal device to achieve a better interference cancellation effect.
In order to increase the effective utilization rate of the radiation power, the radio transmitting terminal increasingly transmits signals in a directional transmission manner, which results in that the interference signals received by the multi-antenna terminal equipment also have better directivity, and some receiving antennas of the multiple receiving antennas of the multi-antenna terminal equipment receive relatively stronger interference signals, which makes it difficult for the multi-antenna terminal equipment to effectively improve the signal quality of the combined signals by using the interference cancellation effect.

It is to be understood that the terms so used are interchangeable under appropriate circumstances and are merely descriptive of the various embodiments of the application and how objects of the same nature can be distinguished.

In order to increase the effective utilization rate of the radiation power, the radio transmitting terminal increasingly transmits signals in a directional transmission manner, so that the interference signals received by the multi-antenna terminal equipment have more directivity, and some receiving antennas of the multiple receiving antennas of the multi-antenna terminal equipment receive relatively stronger interference signals, which makes it difficult for the multi-antenna terminal equipment to effectively improve the signal quality of the combined signals by using the interference cancellation effect.
In order to improve the signal quality of a combined signal of a plurality of receiving antennas under the condition of strong interference in a certain direction, the application provides a control method of the receiving antennas, which is applied to a terminal device, and the terminal device comprises a plurality of receiving antennas. The terminal equipment mentioned in the present application may be any terminal equipment with radio transceiving function, such as User Equipment (UE), mobile or wireless terminal, mobile phone, computer such as for example a laptop, personal digital assistant or tablet computer, and Customer Premises Equipment (CPE), etc. The wireless CPE is a wireless terminal access device for receiving WiFi signals, can replace wireless client devices such as a wireless network card and the like, can receive wireless signals of a wireless router, a wireless AP, a wireless base station and the like, and is a novel wireless terminal access device. Meanwhile, the wireless CPE is also equipment for converting high-speed 4G or 5G signals into WiFi signals, can be widely applied to access of wireless networks in rural areas, towns, hospitals, units, factories, cells and the like, and is favorable for saving the cost of laying a wire network.
Referring to fig. 1, an embodiment of the present application of a method for controlling a receiving antenna includes the following steps:
100. acquiring the signal quality of a receiving antenna in an open state in a plurality of receiving antennas;
for a multi-antenna terminal device, which generally has a plurality of antennas that can be used for receiving signals, an antenna that can be used for receiving signals among the plurality of antennas of the terminal device is referred to as a receiving antenna in this application. The directions of the corresponding transmitted or received signals of the different receiving antennas are usually different. The terminal device may control the receiving direction of each receiving antenna, or control the on-off state (on state or off state) of each receiving antenna, or control the receiving direction and the on-off state of each receiving antenna, and receive signals by using the receiving antenna in the on state among the multiple receiving antennas, and combine the received signals to obtain a combined signal, so as to obtain the diversity gain and the array gain.
200. Controlling the receiving directions or the switch states of a plurality of receiving antennas according to the acquired signal quality;
the terminal device may control the receiving directions or the on-off states of the multiple receiving antennas according to the acquired signal quality, so as to optimize the signal quality of the combined signal of the multiple receiving antennas. By controlling the receiving direction of each of the plurality of receiving antennas, or by controlling the on-off state of each of the plurality of receiving antennas, or by controlling the receiving direction and the on-off state of each of the plurality of receiving antennas, the direction of the received signal can be controlled, that is, the direction of which signals are received can be selected, and the direction of which signals are not received can be selected. Because the signal quality of the signal received by the receiving antenna (referred to as the signal quality of the receiving antenna for short) can reflect the strength of the interference signal, and the interference signal generally has strong directivity, the direction of the interference signal can be determined according to the signal quality of the receiving antenna in the on state, and then the receiving direction and/or the on-off state of each receiving antenna in the plurality of receiving antennas can be controlled, which is beneficial to reducing the received interference signal, thereby optimizing the signal quality of the combined signal of the plurality of receiving antennas.
The Signal Quality mentioned in the present application may be, for example, any one of a Signal to Interference Noise Ratio (SINR), a Reference Signal Received Power (RSRP), a Received Signal Strength Indicator (RSSI), and a Reference Signal Received Quality (RSRQ).
With regard to controlling the reception directions of the plurality of reception antennas, alternatively, the terminal device may control the reception directions of the reception antennas by adjusting the direction of a single reception antenna with respect to the main body, or alternatively, the terminal device may control the reception directions of the reception antennas by adjusting the direction of the reception antennas as a whole with respect to the main body or adjusting the orientation of the terminal device. For example, for the wireless CPE fixed on the outer wall of the house, the wireless CPE may be fixed on the outer wall of the house through a rotatable base, and the wireless CPE may control the base to rotate by a certain angle according to the signal quality of the receiving antenna, so as to adjust the direction of the receiving antenna to receive the signal.
In one possible implementation manner, referring to fig. 2, in step 200, the controlling, by the terminal device, the switching states of the multiple receiving antennas according to the signal qualities of the multiple receiving antennas may specifically include the following steps:
201. determining a target receiving antenna from the receiving antennas in the on state according to the acquired signal quality;
after the terminal device obtains the signal quality of the receiving antenna in the on state from the multiple receiving antennas, a part of the receiving antennas may be selected from the receiving antennas in the on state according to the obtained signal quality, and the selected part of the receiving antennas receives a stronger interference signal relative to other receiving antennas in the on state.
202. The target receiving antenna is turned off.
After the terminal device determines the target receiving antenna, the target receiving antenna may be turned off to be in a turned-off state. It should be noted that the receiving antenna in the off state only indicates that the antenna is not used for receiving signals temporarily, but alternatively, the antenna may be used for transmitting signals.
Exemplarily, referring to fig. 3, another embodiment of the control method for a receiving antenna of the present application may include the following steps:
100a, acquiring the signal quality of a receiving antenna in an open state in a plurality of receiving antennas;
201a, determining a target receiving antenna from the receiving antennas in an open state according to the acquired signal quality;
202a, the target receiving antenna is turned off.
In the embodiment corresponding to fig. 3, reference may be made to the description of the foregoing corresponding steps, which is not described herein again. The corresponding step described above, such as step 100a, is step 100.
In one possible implementation, the worse signal quality antenna may be considered to receive the stronger interference signal, and therefore, the target receiving antenna may be the receiving antenna with worse signal quality relative to other receiving antennas in the on state, or the target receiving antenna may have worse signal quality than other receiving antennas in the on state. Illustratively, two methods of determining the target receive antenna are provided below:
the first method, step 201, may specifically include:
2011a, calculating the combined signal quality of the receiving antenna in the on state;
after the terminal device obtains the signal quality of each receiving antenna in the on state, the combined signal quality of the receiving antennas in the on state may be calculated by using multiple methods to simulate the signal quality of a combined signal obtained by combining the signals received by the receiving antennas in the on state by the terminal device.
2012a, determining the receiving antenna having the signal quality inferior to the combined signal quality.
After the terminal device calculates the quality of the combined signal, the receiving antenna with the signal quality inferior to the quality of the combined signal can be determined as the target receiving antenna.
The second method and the step 201 may specifically include:
2011b, sequencing the receiving antennas in the on state according to the quality of the signals;
specifically, the receiving antennas may be sorted in an ascending order or in a descending order according to the quality of the signal.
2012b and selecting one or more receiving antennas with the relatively worst signal quality from the sorted receiving antennas.
The relatively worst plurality of receiving antennas among the receiving antennas in the on state means that the signal quality of any selected receiving antenna is inferior to that of the unselected receiving antennas, that is, only a part of the receiving antennas are selected as the target receiving antennas. Since the number of the receiving antennas in the on state may change, in order to ensure that the receiving antennas are still in the on state after the target receiving antenna is selected, the proportion of the target receiving antenna in the receiving antennas in the on state may be preset, for example, 30%, the designated number of the target receiving antennas is determined according to the preset proportion, and then the designated number of the receiving antennas with the worst signal quality is selected from the sorted receiving antennas.
In some embodiments of the present application, after step 100 and before step 201, the method for controlling a receiving antenna of the present application may further include the following steps:
300. judging whether the combined signal quality of the receiving antenna in the on state is inferior to a signal quality threshold according to the acquired signal quality, if so, executing step 201, and if so, executing other operations;
after the terminal device obtains the signal quality of the receiving antenna in the on state from the multiple receiving antennas, the combined signal quality of the receiving antenna in the on state may be calculated, which may refer to step 2011a and is not described herein again. The terminal device may determine whether the combined signal quality of the receiving antennas in the on state is inferior to the signal quality threshold, if the combined signal quality of the receiving antennas in the on state is inferior to the signal quality threshold, step 201 is executed, and if the combined signal quality of the receiving antennas in the on state is inferior to the signal quality threshold, other operations than step 201 are executed, for example, step 100 may be executed again. If the combined signal quality of the receiving antennas in the 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 herein.
Illustratively, referring to fig. 4, another embodiment of the control method for a receiving antenna of the present application may include the following steps:
100b, acquiring the signal quality of a receiving antenna in an open state in a plurality of receiving antennas;
300b, judging whether the quality of the combined signal is inferior to a signal quality threshold value, if so, executing the step 201b, and if not, executing the step 100b;
201b, determining a target receiving antenna from the receiving antennas in the on state according to the acquired signal quality;
202b, the target receiving antenna is switched off.
In the embodiment corresponding to fig. 4, reference may be made to the description of the foregoing corresponding steps, which is not described herein again. The corresponding step described previously, such as step 100b, is step 100.
In order to enable the control method for the receiving antenna provided by the present application to adapt to the variability of the interference signal and effectively improve the signal quality of the combined signal for a long time, in a possible implementation manner, any one of the above embodiments of the control method for the receiving antenna may be taken as a single loop, and the terminal device may repeatedly execute any one of the above embodiments of the control method for the receiving antenna. For example, in some embodiments of the present application, the terminal device may repeatedly execute the embodiment corresponding to fig. 3, that is, the embodiment corresponding to fig. 3 is taken as a single loop, and after executing step 202a, the terminal device may enter the next loop and execute step 100a again.
The terminal device may immediately enter the next cycle after executing a single cycle (such as 100a-201a-202 a) of the control method for the receiving antenna, that is, immediately execute step 100a, or may execute step 100a again after a period of time, or may execute step 100a again when the cycle trigger condition is satisfied.
In some embodiments of the present application, after step 202, the method for controlling a receiving antenna of the present application may further include the following steps:
400. judging whether a cycle triggering condition is met, if so, executing the step 100, and if not, executing the step 500;
in a possible implementation manner, the cycle trigger condition may be that the number of the receiving antennas in the on state in the multiple receiving antennas is greater than a number threshold, or in a possible implementation manner, the cycle trigger condition may be that the downlink data transmission rate of the terminal device is higher than a transmission rate threshold, or in a possible implementation manner, the cycle trigger condition may be that the number of the receiving antennas in the on state in the multiple receiving antennas is greater than the number threshold, and the downlink data transmission rate of the terminal device is higher than the transmission rate threshold.
500. Performing other operations;
if the terminal device determines that the loop triggering condition is not satisfied, other operations than step 100 may be performed, for example, the step 400 is executed again after waiting for a preset time period.
Illustratively, referring to fig. 5, another embodiment of the control method for a receiving antenna of the present application may include the following steps:
100c, acquiring the signal quality of a receiving antenna in an open state in a plurality of receiving antennas;
201c, determining a target receiving antenna from the receiving antennas in the opening state according to the acquired signal quality;
202c, closing the target receiving antenna;
400c, judging whether the number of the receiving antennas in the opening state is larger than the number threshold, if so, executing the step 100c, and if not, executing the step 400c again.
In the embodiment corresponding to fig. 5, reference may be made to the description of the foregoing corresponding steps, which is not described herein again. The corresponding step described above, such as step 100c, is step 100.
In one possible implementation manner of the present application, step 500 may specifically include the following steps:
501. turning on all of a plurality of receiving antennas;
in step 400, if the terminal device determines that the loop triggering condition is not satisfied, the terminal device may turn on all receiving antennas of the multiple receiving antennas, and receive the signal using all antennas available for receiving the signal. Then, 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.
For example, referring to fig. 6, another embodiment of the method for controlling a receiving antenna of the present application may include the following steps:
100d, acquiring the signal quality of a receiving antenna in an open state in a plurality of receiving antennas;
201d, determining a target receiving antenna from the receiving antennas in the opening state according to the acquired signal quality;
202d, turning off the target receiving antenna;
400d, judging whether the transmission rate of the downlink data of the terminal equipment is higher than a transmission rate threshold, if so, executing the step 100d, and if not, executing the step 501d;
501d, all of the plurality of receiving antennas are turned on, and step 400d is triggered.
For each step in the embodiment corresponding to fig. 6, reference may be made to the description of the corresponding step, which is not described herein again. The corresponding step described above, such as step 100d, is step 100.
In some embodiments, after step 202, the embodiments of the present application may further include the following steps:
600. if the closing time length of the target receiving antenna exceeds a time length threshold value, the target receiving antenna is started;
after the target receiving antenna is turned off, the terminal device may start a timer, and when the duration of the timer exceeds a duration threshold, the terminal device may start the target receiving antenna corresponding to the timer. For example, assuming that the receiving antenna of the terminal device in the on state includes 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 is executed, the terminal device turns off antenna 2 and turns on timer 2, and when the duration recorded by timer 1 exceeds the duration threshold, the terminal device may 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 the receiving antennas 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 thresholds corresponding to different receiving antennas may be different, and for example, the duration threshold may be positively correlated with the historical turning-off times of the target receiving antenna. In some embodiments, the embodiments of the present application may further include the following steps:
700. determining a time length threshold value according to the historical closing times of the target receiving antenna;
after the terminal device determines the target receiving antenna, a time length threshold value can be determined according to the historical closing times of the target receiving antenna, and the time length threshold value is positively correlated with the historical closing times of the target receiving antenna. Illustratively, the time duration threshold of the target receiving antenna = N × T, where N is the historical turn-off number of the target receiving antenna, T is a preset fixed time duration, assuming that T is 1 minute, the historical turn-off number of the receiving antenna 1 is 1 time, and the historical turn-off number of the antenna 2 is 5 times, and when the terminal device executes the current loop, the determined target antenna includes the antenna 1 and the antenna 2, then the terminal device may determine that the time duration threshold of the receiving antenna 1 is 1 minute, and the time duration threshold of the antenna 2 is 5 minutes.
