The switching scheme based on the antenna system 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.
Fig. 1 shows a flowchart of a switching method based on an antenna system according to an embodiment of the present application, where the method 100 may be performed by a terminal device, in other words, the method may be performed by software or hardware installed in the terminal device, as shown in fig. 1, and the method includes the following steps.
S101, obtaining a first RSSI of a first antenna of terminal equipment and a first transmission power amplitude reduction of the first antenna.
The first antenna is a working antenna of the terminal device. In the embodiment of the present application, an operating antenna refers to an antenna that is used as a terminal device to transmit or receive signals under a certain signal reception strength. That is, the first antenna is in an operating state, and serves as a transmitting antenna of the terminal device to transmit signals outwards.
In the present application, an RSSI compensation mechanism is added when determining whether to perform antenna switching, that is, the transmission power reduction of the antenna is considered. Therefore, the RSSI of the antenna is obtained, and simultaneously, the transmission power reduction amplitude of the antenna is also obtained.
S102, obtaining a second RSSI of a second antenna of the terminal equipment and a second transmission power reduction amplitude of the second antenna.
And the second antenna is a non-working antenna of the terminal equipment. That is, the second antenna is not in operation.
S103, determining whether to switch the working antenna of the terminal equipment or not according to at least the first RSSI, the first transmission power reduction amplitude, the second RSSI and the second transmission power reduction amplitude.
In the method provided by the embodiment of the application, when the working antennas are switched, the transmission power reduction amplitude of each antenna is considered, so that the problem that the antenna cannot be switched to a better antenna to work under the condition that the transmission power reduction amplitude of the antenna is obviously changed but the RSSI is not obviously changed can be solved, the antenna works in a more appropriate state, and the communication quality of the terminal equipment is ensured.
In one possible implementation, S103 may include: and if the difference value between the first value and the second value is not larger than a first threshold value, switching the second antenna to be a working antenna of the terminal equipment, and switching the first antenna to be a non-working antenna of the terminal equipment, wherein the first value is the difference value between the first RSSI and the first transmission power reduction amplitude, and the second value is the difference value between the second RSSI and the second transmission power reduction amplitude.
Fig. 2a shows a schematic layout of an antenna system of a terminal device, and as shown in fig. 2a, an antenna 1 and an antenna 2 are provided on the terminal device, and a PA selects an operating antenna through a selection switch. In fig. 2a, if neither antenna 1 nor antenna 2 reaches the sensor (sensor) triggered SAR reduction scenario, at this time, both the first transmit power reduction amplitude a of antenna 1 and the second transmit power reduction amplitude B of antenna 2 are 0dB, and at this time, the determination mechanism for antenna switching is the same as a common determination mechanism, that is, it is determined whether the difference between RSSI1 and RSSI2 reaches the first threshold X, so that the antenna switching determination is performed.
If the antenna 2 is in the free space state, the antenna 1 is close to a certain object and reaches a sensor triggering SAR reduction scene, the first transmission power reduction amplitude of the antenna 1 is A dB, but the RSSI1 is not seriously affected, namely, the RSSI1 and the free space state are hardly different, at this time, after the compensation value A is added, the judgment mechanism is changed into whether the difference value between the RSSI1-A and the RSSI2 is larger than a first threshold value X, so that whether the antenna 2 is switched or not is judged.
If the antenna 1 and the antenna 2 are both close to each other by an object and both reach the condition of triggering power reduction, the transmission power is respectively reduced by A dB and B dB, but the RSSI1 and the RSSI2 are not obviously affected, and at the moment, the judgment mechanism is that whether the difference value between the RSSI1-A and the RSSI2-B is greater than a first threshold value X or not, so that whether the antenna is switched or not is judged.
If the antenna 1 is completely covered by an object (such as being held or covered by other metal), the trigger transmission power is reduced by A dB, and meanwhile, the RSSI1 is also affected, at the moment, the difference value between the RSSI1-A and the RSSI2-B of the judgment mechanism does not meet the first threshold value X, the antenna is switched to the antenna 2 to work, and the terminal equipment is prevented from being incapable of realizing communication.
If the antenna 2 is completely covered by an object (such as being held or covered by other metal), the trigger transmission power is reduced by B dB, and the RSSI2 is also affected, at this time, the difference between the RSSI1-a and the RSSI2-B of the determination mechanism satisfies the first threshold X, the antenna switching is maintained to work at the antenna 1, and the terminal device is prevented from being unable to communicate.
Fig. 2b is a schematic diagram illustrating a determination flow of antenna switching under the layout of the antenna system shown in fig. 2 a. As shown in fig. 2B, after the SAR scene trigger, the Application Processor (AP) obtains the transmission power reduction a of the antenna 1 and the transmission antenna power reduction B of the antenna 2 triggered by the SAR scene, controls the transmission power of the antenna 1 to be reduced from the maximum transmission power Tx1 by a, that is, the transmission power of the antenna 1 is Tx1-a, and controls the transmission power of the antenna 2 to be reduced from the maximum transmission power Tx2 by a, that is, the transmission power of the antenna 2 is Tx 2-B. In addition, the AP acquires RSSI1 of antenna 1 and RSSI2 of antenna 2 from the modem (modem), determines a relationship between a difference between the first value (RSSI1-a) and the second value (RSSI2-B) and the first threshold value X, and when the difference between the first value (RSSI1-a) and the second value (RSSI2-B) is greater than the first threshold value X, keeps the operating antenna, i.e., antenna 1, operating (i.e., DPDT is in the antenna 1 state), and controls the PA to keep the selector switch in the path of antenna 1. When the difference between the first value (RSSI1-a) and the second value (RSSI2-B) is not greater than (i.e., is less than or equal to) the first threshold value X, the operating antenna is switched to antenna 2 (i.e., DPDT is in the antenna 2 state), the PA is controlled to switch the selector switch to the path of antenna 2, so that antenna 2 is switched to the operating state and antenna 1 is switched to the non-operating state.
In another possible implementation manner, S103 may further include: if the difference between the first RSSI and the second RSSI is not greater than a first threshold or the difference between the first transmission power of the first antenna and the second transmission power of the second antenna is not greater than a second threshold, switching the second antenna to a working antenna of the terminal device, and switching the first antenna to a non-working antenna of the terminal device, wherein the first transmission power is the difference between the maximum transmission power of the first antenna and the first transmission power reduction amplitude, and the second transmission power is the difference between the maximum transmission power of the second antenna and the second transmission power reduction amplitude.
For example, fig. 3 shows another switching determination diagram in the antenna layout shown in fig. 2a, and as shown in fig. 3, the AP determines the relationship between the difference between RSSI1 and RSSI2 and the first threshold value X and the relationship between the difference between Tx1-a and Tx2-B and the second threshold value Y. When the difference between RSSI1 and RSSI2 is greater than a first threshold X and the difference between Tx1-a and Tx2-B is greater than a second threshold Y, antenna 1 is operated, and when the difference between RSSI1 and RSSI2 is not greater than the first threshold X or the difference between Tx1-a and Tx2-B is not greater than the second threshold Y, antenna 2 is switched to be operated.
In the possible implementation manner provided by the embodiment of the present application, another determination condition is added to the original RSSI determination mechanism for determining whether the transmission power satisfies the handover mechanism, so that the antenna handover mechanism can be satisfied. Meanwhile, the state of the transmitting antenna under certain trigger power reduction scenes is considered, so that the antenna works in a more appropriate state, and the communication experience of a user is ensured.
In one possible implementation, the terminal device may be provided with three antennas, for example, in fig. 4a, considering that the terminal device may have a landscape use scenario, in such a scenario, the antennas provided at the upper and lower ends of the terminal device may be both held, which may result in a reduction in communication quality of the terminal device. Thus, as shown in fig. 4a, one antenna 3 may be provided on the long side of the terminal device, and the PA selects the operating antenna by means of two selection switches. Thus, in this possible implementation, S103 may include: if the difference between the first numerical value and the second numerical value is greater than a first threshold value, and the difference between the first numerical value and the third numerical value is greater than a third threshold value, the first antenna is kept as a working antenna of the terminal device, wherein the third numerical value is a difference between a third RSSI and a third transmission power reduction amplitude, the third RSSI is an RSSI of a third antenna of the terminal device, the third transmission power reduction amplitude is a transmission power reduction amplitude of the third antenna, and the third antenna is a non-working antenna of the terminal device.
Optionally, in the foregoing possible implementation manner, S103 may further include: if the difference value between the first numerical value and the second numerical value is not larger than a first threshold value or the difference value between the first numerical value and the third numerical value is not larger than a third threshold value, judging the difference value between the second numerical value and the third numerical value; if the difference between the second numerical value and the third numerical value is larger than a fourth threshold value, switching the working antenna of the terminal device to the second antenna, and if the difference between the second numerical value and the third numerical value is not larger than the fourth threshold value, switching the working antenna of the terminal device to the third antenna.
Fig. 4b is a schematic diagram illustrating another determination flow of antenna switching under the layout of the antenna system shown in fig. 4 a. As shown in fig. 4B, after the SAR scene trigger, the AP obtains a transmission power reduction a of the antenna 1, a transmission antenna power reduction B of the antenna 2, and a transmission antenna power reduction C of the antenna 3 triggered by the SAR scene, controls the transmission power of the antenna 1 to be reduced from the maximum transmission power Tx1, i.e., the transmission power of the antenna 1 is Tx1-a, controls the transmission power of the antenna 2 to be reduced from the maximum transmission power Tx2, i.e., the transmission power of the antenna 2 is Tx2-B, and controls the transmission power of the antenna 3 to be reduced from the maximum transmission power Tx3, i.e., the transmission power of the antenna 3 is Tx 3-C. In addition, the AP acquires RSSI1 of the antenna 1, RSSI2 of the antenna 2, and RSSI3 of the antenna 3 from a modem (modem), determines a relationship between a difference between the first value (RSSI1-a) and the second value (RSSI2-B) and a first threshold value X and a relationship between a difference between the first value (RSSI1-a) and the third value (RSSI3-C) and a third threshold value M, respectively, and when the difference between the first value (RSSI1-a) and the second value (RSSI2-B) is greater than the first threshold value X and the difference between the first value (RSSI1-a) and the third value (RSSI3-C) is greater than the third threshold value M, keeps the antenna 1 in operation (i.e., DPDT is in the antenna 1 state), controls the PA to keep the selector switch in the path of the antenna 1, wherein: RSSI3 is the received signal strength indication for antenna 3 and C is the third transmit power reduction for antenna 3. When the difference between the first value (RSSI1-a) and the second value (RSSI2-B) is not greater than the first threshold value X or the difference between the first value (RSSI1-a) and the third value (RSSI3-C) is not greater than the third threshold value M, continuing to determine the relationship between the difference between the second value (RSSI2-B) and the third value (RSSI3-C) and the fourth threshold value Z, switching the operating antenna to the antenna 2 operating state (i.e., DPDT antenna 2 state) if the difference between the second value (RSSI2-B) and the third value (RSSI3-C) is greater than the fourth threshold value Z, controlling the PA to switch the selector switch to the path of the antenna 2, thereby switching the antenna 2 to the operating state, switching the antenna 1 to the non-operating state, and if the difference between the second value (RSSI2-B) and the third value (RSSI3-C) is not greater than the fourth threshold value Z, the operating antenna is switched to antenna 3 operation (i.e. DPDT is in antenna 3 state) and the PA is controlled to switch the selection switch to the path of antenna 3, so that antenna 3 is switched to the operating state and antenna 1 is switched to the non-operating state.
In the possible implementation manners provided by the embodiment of the application, the third antenna is added on the basis of the two antenna embodiments, and consideration on a trigger power reduction scene is added, so that the performance of the antenna system is further optimized, the antenna can work in a more appropriate state, and the communication experience of a user is ensured.
In one possible implementation, the terminal device may be provided with four antennas, for example, in fig. 5a, considering that the terminal device may have a usage scenario of holding with two hands, in such a scenario, one side of each of the antennas disposed at the left and right ends and the upper and lower ends of the terminal device may be held, which may result in a reduction in communication quality of the terminal device, as shown in fig. 5a, an antenna 3 and an antenna 4 may be disposed on the long sides of the two sides of the terminal device, and the PA selects the working antenna through two selection switches. Therefore, in this possible implementation manner, the switching method based on the antenna system may further include:

As shown in fig. 5b, on the basis of the embodiment of fig. 2b, after the SAR scene trigger, the AP further obtains a transmission power reduction C of the antenna 3 and a transmission antenna power reduction D of the antenna 4 triggered by the SAR scene, controls the transmission power of the antenna 3 to be reduced from the maximum transmission power Tx3 by C, that is, the transmission power of the antenna 3 is Tx3-C, and controls the transmission power of the antenna 4 to be reduced from the maximum transmission power Tx4 by D, that is, the transmission power of the antenna 4 is Tx 4-D. In addition, the AP acquires the RSSI3 of the antenna 3 and the RSSI4 of the antenna 4 from the modem (modem), determines the relationship between the difference between the first value (RSSI1-a) and the second value (RSSI2-B) and the first threshold value X, then continues to determine the relationship between the difference between the fourth value (RSSI3-C) and the fifth value (RSSI4-D) and the fifth threshold value N, and if the difference between the fourth value (RSSI3-C) and the fifth value (RSSI4-D) is greater than the fifth threshold value N, keeps the antenna 3 in operation (i.e., DPDT is in the antenna 3 state), and controls the PA to keep the selection switch in the path of the antenna 3. If the difference between the fourth value (RSSI3-C) and the fifth value (RSSI4-D) is not greater than the fifth threshold N, the antenna 4 is switched to operate (i.e. DPDT is in the antenna 4 state), the PA is controlled to switch the selection switch to the path of the antenna 4, so that the antenna 4 is switched to the operating state and the antenna 3 is switched to the non-operating state.
