All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.

It is to be understood that the data so used is interchangeable under appropriate circumstances such that the embodiments of the application are capable of operation in sequences other than those illustrated or described herein. In addition, "and/or" in the specification and claims means at least one of connected objects, a character "/" generally means that a preceding and succeeding related objects are in an "or" relationship.
The antenna selection method provided by the embodiment of the present application is described in detail below with reference to the accompanying drawings through specific embodiments and application scenarios thereof.
Referring to fig. 1, fig. 1 is a flowchart of an antenna selection method according to an embodiment of the present application, and as shown in fig. 1, the method includes the following steps:
It should be noted that the method provided in the embodiment of the present application is applied to an electronic device provided with an antenna, such as a mobile phone, a computer, a tablet computer, a notebook computer, a wearable device, and the like, and an execution main body of the present application may be the electronic device, or may also be an antenna selection device in the electronic device. In the following detailed description of the present embodiment, the implementation subject will be specifically described as an antenna selection apparatus. In addition, the method provided by the application can be applied to the multi-antenna technology of the electronic equipment, namely a multi-antenna system arranged in the electronic equipment.
In the embodiment of the present application, a Received Signal Strength Indication (RSSI), a transmission path insertion loss value, and a reception path insertion loss value of each antenna in N antennas are obtained.
Wherein the rssi value is indicative of a signal strength of the antenna, and the rssi value is not a constant value; for example, the received signal strength indicator may be larger where the electronic device is closer to the base station, or the received signal strength indicator may be smaller when the electronic device is in an enclosed space such as an elevator. In the embodiment of the present application, the antenna selection apparatus may obtain the received signal strength indication value of the antenna in real time, or may obtain the received signal strength indication value of the antenna when the electronic device is changed in position.
It will be appreciated that each antenna includes a corresponding transmit path and receive path, i.e., a corresponding transmit path insertion loss value and receive path insertion loss value, to characterize the signal attenuation of the antenna's transmit and receive signals. Optionally, the transmission path insertion loss value and the reception path insertion loss value corresponding to each antenna may be fixed values, and the antenna selection device may test and store the transmission path insertion loss value and the reception path insertion loss value of each antenna in advance.
Optionally, the step 101 may include:
and acquiring a preset transmitting path insertion loss value and a preset receiving path insertion loss value corresponding to each antenna in the N antennas, and acquiring a received signal strength indicated value of each antenna in real time.
The preset transmission path insertion loss value and the preset receiving path insertion loss value are values stored by the antenna selection device, wherein the values are the transmission path insertion loss value and the receiving path insertion loss value of each antenna which are tested in advance by the antenna selection device. The real-time obtaining of the received signal strength indication value of each antenna may be periodically obtaining the received signal strength indication value of each antenna, for example, may be obtaining every 10 s. Therefore, when the position of the electronic equipment is changed, the indication value of the strength of the received signal after each antenna is changed can be timely acquired, so that the accuracy of the result of the compensation calculation of each antenna is improved.
And step 102, obtaining the signal strength of each antenna according to the received signal strength indicating value, the transmitting path insertion loss value and the receiving path insertion loss value, and determining a target antenna, wherein the target antenna is the antenna with the strongest signal strength in the N antennas.
Wherein the target antenna is the one with the strongest signal strength among the N antennas. For example, after performing compensation calculation on the signals of the antennas, the antenna with the largest signal strength value may be selected as the target antenna according to the result of the compensation calculation. The strength of the signal strength can be determined by the detected signal strength value, and the stronger the signal strength, the larger the signal strength value, otherwise, the smaller the signal strength value.
Optionally, the step 102 may include:
performing compensation calculation on the signal of each antenna according to the received signal strength indicated value, the transmitting path insertion loss value and the receiving path insertion loss value of each antenna to obtain a compensated signal strength value of each antenna;
and determining the antenna with the maximum signal strength value as a target antenna.
It is understood that the transmission path insertion loss value and the reception path insertion loss value corresponding to each antenna are fixed values, and the received signal strength indication value is a variable value, which may vary based on a change in the position of the electronic device, for example; then, in different positions or in different scenes, the received signal strength indication values corresponding to the antennas may be different, and further, the result of performing compensation calculation on the antennas may also change based on the change of the position or the scene, and the antenna with the optimal signal strength in different positions or scenes may also change, so that the obtained target antennas may also be different.
In the embodiment of the present application, the compensation calculation is performed on the signal of each antenna according to the received signal strength indication value, the transmission path insertion loss value, and the reception path insertion loss value of each antenna, for example, the transmission path insertion loss value is subtracted from the sum of the received signal strength indication value and the reception path insertion loss value, so as to calculate and obtain the signal strength value after antenna compensation.
Optionally, in a specific embodiment, the signal strength value is a difference between a first value and a second value, the first value is a sum of the received signal strength indication value and a received path insertion loss value, and the second value is the transmitted path insertion loss value.
That is, the signal strength value is the received signal strength indicator value + the received path insertion loss value-the transmit path insertion loss value.
It is understood that the transmission path insertion loss value and the reception path insertion loss value corresponding to each antenna are constant values, and the received signal strength indication value is non-constant value. Under different scenes, the received signal strength indicating values corresponding to the antennas are different, and then the signal strength values obtained after compensation calculation of the antennas under different scenes are different.
For example, when the electronic device is located indoors, the received signal strength indicator value RSQ1 of antenna 1 is greater than the received signal strength indicator value RSQ2 of antenna 2, then after performing compensation calculation on antenna 1 and antenna 2 in this scenario, the signal strength value of antenna 1 is greater than the signal strength value of antenna 2, and then antenna 1 is the target antenna. If the received signal strength indicated value RSQ1 of antenna 1 is smaller than the received signal strength indicated value RSQ2 of antenna 2 when the electronic device is switched outdoors, then after performing compensation calculation for antenna 1 and antenna 2 outdoors, the signal strength value of antenna 1 is smaller than the signal strength value of antenna 2, and then antenna 2 is the target antenna. Therefore, the uplink signal quality of each antenna can be accurately judged in the multi-antenna system, so that the uplink signal is transmitted through the target antenna, and the communication quality of the electronic equipment is improved.
And 103, transmitting uplink signals through the target antenna.
It can be understood that, after the signal of each antenna is compensated and calculated through the received signal strength indication value, the transmission path insertion loss value and the reception path insertion loss value, and the target antenna is determined, uplink signal transmission is performed through the target antenna, so that the electronic device can switch the uplink transmission signal to the optimal antenna position, and the communication quality of the electronic device is improved.
In this application, compare in prior art and simply regard as the basis of judging with descending received signal quality, the scheme that this application provided has introduced the judgement to ascending transmitted signal quality, and then through combining ascending transmitted signal quality and descending received signal quality, carries out corresponding compensation calculation to each received signal for the unbalance of transmitted signal on the hardware access for the signal strength judged result to the antenna is more accurate, and then with the communication quality who promotes electronic equipment.
It should be noted that, in this embodiment of the present application, the received signal strength indication value corresponding to each antenna may be obtained in real time, and then, after the received signal strength indication value corresponding to the antenna changes, the compensation calculation is performed again on the antenna signal according to the changed received signal strength indication value, so as to determine the target antenna again, and perform uplink signal transmission through the determined target antenna. That is, when the received signal strength indication value corresponding to the antenna changes, step 102 and step 103 are repeated. Therefore, the target antenna can be timely adjusted according to the change of the antenna received signal strength indication value, and the communication quality of the electronic equipment is further improved.
In order to better understand the technical solutions provided in the present application, the following description will be given by way of a specific example.
Referring to fig. 2, fig. 2 is a structural diagram of a radio frequency communication system in an electronic device applying the antenna selection method provided in the present application. The radio frequency transceiver modulates and demodulates the radio frequency signal; p1, P2, P3 and P4 are schematic diagrams of rf front-end devices on rf paths of part 1, part 2, part 3 and part 4 respectively, and corresponding antennas thereof are ANT1, ANT2, ANT3 and ANT4 respectively; SW1 is SP4T, a single pole, four throw switch, for switching different antenna paths; SW2, SW3, SW4 are SPDT, i.e., single pole double throw switches, for switching transmission and reception.
It can be seen from fig. 2 that there is a radio frequency Transmit (TX) path and a Receive (RX) path, where:
TX 1: p1 to SW1 to ANT1, the launch path insertion loss value is TL 1;
TX 2: P1-SW 1-SW 2-ANT 2, the launch path insertion loss value is TL 2;
TX 3: P1-SW 1-SW 3-ANT 3, the launch path insertion loss value is TL 3;
TX 4: P1-SW 1-SW 4-ANT 4, the launch path insertion loss value is TL 4;
RX 1: ANT 1-SW 1-P1, the receive path insertion loss value is RL 1;
RX 2: ANT 2-SW 2-P2, the receive path insertion loss value is RL 2;
RX 3: ANT 3-SW 3-P3, the receive path insertion loss value is RL 3;
RX 4: ANT4 to SW4 to P4, the receive path insertion loss value is RL 4.
In the operation of the radio frequency communication system, the four receiving paths RX1, RX2, RX3 and RX4 all receive at the same time, and demodulate the signal strength of the base station to obtain the received signal strength indicating value, in this embodiment, it is assumed that the received signal strength indicating values corresponding to the four receiving paths are RSSI1, RSSI2, RSSI3 and RSSI4, respectively.
In this embodiment, after obtaining the received signal strength indication value RSSI, the transmission path insertion loss value TL, and the reception path insertion loss value RL corresponding to each antenna, respectively, compensation calculation is performed according to the RSSI, TL, and RL of each antenna, so as to obtain a compensated signal strength value RSQ of each antenna, where a specific calculation method is as follows:
RSQ1＝RSSI1+RL1–TL1；
RSQ2＝RSSI2+RL2–TL2；
RSQ3＝RSSI3+RL3–TL3；
RSQ4＝RSSI4+RL4–TL4。
further, the calculated signal strength values RSQ1, RSQ2, RSQ3 and RSQ4 are compared with each antenna, and the antenna with the maximum signal strength value is determined as a target antenna, and uplink signal transmission is performed through the target antenna. For example, assuming that the signal strength value RSQ1 is maximum, ANT1 is determined as a target antenna.
Therefore, by combining the quality of the uplink transmitting signal and the quality of the downlink receiving signal, corresponding compensation calculation is carried out on the imbalance of each receiving signal on the hardware access relative to the transmitting signal, so that the signal strength judgment result of the antenna is more accurate, and the communication quality of the electronic equipment is improved.
