Detailed Description
Before describing the technical solution of the embodiment of the present invention in detail, a description will be given of a related art.
Fig. 1 is a schematic diagram of a structure of an antenna switching circuit in the related art, and as shown in fig. 1, the radio frequency circuit includes two antennas, one antenna is denoted by TRX, which represents that the antenna is used for transmitting radio frequency signals and receiving radio frequency signals in a main set form, the other antenna is denoted by DRX, which represents that the antenna is used for receiving radio frequency signals in a diversity form, and the two antennas are switched by a double-pole double-throw switch (DPDT), so as to implement main set reception and diversity reception. However, this antenna switching method is not flexible enough, and is only applicable to a main diversity antenna switching scenario, which is limited in the application scenario.
Based on this, in various embodiments of the present invention, an antenna switching circuit includes: the antenna unit comprises a first antenna and a second antenna; the first antenna is used for transmitting radio frequency signals and receiving the radio frequency signals in a main set form, and the second antenna is used for receiving the radio frequency signals in a diversity form; the control unit is used for determining the current required capability information of the terminal; generating a control instruction according to the capability information; the first switch unit is used for responding to the control instruction and controlling the first antenna and the second antenna to be switched from a first working mode to a second working mode; in the first working mode, the first antenna and the second antenna respectively work independently; and under the second working mode, the first path of antenna and the second path of antenna are switched to form an antenna array to work together, so that the current required capability of the terminal is met.
It should be noted that, in the embodiment of the present invention, the antenna unit includes, but is not limited to, two antennas, and taking the case that the antenna unit includes two antennas as an example, the antennas can be switched according to the currently required capability requirement of the terminal, and an antenna array is formed, and the currently required capability of the terminal is satisfied by the formed antenna array.
The present invention will be described in further detail with reference to the accompanying drawings and specific embodiments.
Fig. 2 is a schematic diagram illustrating a structure of an antenna switching circuit according to an embodiment of the present invention; as shown in fig. 2, includes:
an antenna unit 21 including a first antenna and a second antenna; the first antenna is used for transmitting radio frequency signals and receiving the radio frequency signals in a main set form, and the second antenna is used for receiving the radio frequency signals in a diversity form;
a control unit 22 for determining capability information currently required by the terminal; generating a control instruction according to the capability information;
the first switch unit 23 is configured to respond to the control instruction, and control the first antenna and the second antenna to switch from the first operating mode to the second operating mode; in the first working mode, the first antenna and the second antenna respectively work independently; and under the second working mode, the first path of antenna and the second path of antenna are switched to form an antenna array to work together, so that the current required capability of the terminal is met.
Here, in practical application, the first antenna is a transceiver antenna, that is, the first antenna can transmit a radio frequency signal and can receive a radio frequency signal in a master set manner. The second antenna is an antenna capable of receiving only radio frequency signals, that is, the second antenna can receive radio frequency signals in a diversity mode.
Here, the first antenna and the second antenna are two antennas with different structures, and in the case of independent operation, the first antenna is connected to a TRX in the radio frequency circuit, and the second antenna is connected to a DRX in the radio frequency circuit. Under the condition of common work, as a possible implementation manner, the second path of antenna is not connected with DRX in the radio frequency circuit, but is switched into the first path of antenna, so that the two paths of antennas are connected with TRX in the radio frequency circuit together, and the two paths of antennas are superposed; as another possible implementation manner, the first antenna is not connected to the TRX in the radio frequency circuit, but is switched to the second antenna, so that the two antennas are connected to the DRX in the radio frequency circuit together, thereby implementing the superposition of the two antennas.
Here, considering that the switching manner is not flexible enough due to that the two antennas of the antenna unit 22 can only perform circuit switching in the main set and the diversity in the related art, the control unit 22 determines currently required capability information, and controls the two antennas of the antenna unit 22 to perform switching with the transceiving capability required by the terminal according to the currently required capability information of the terminal, so as to satisfy the uplink throughput and the downlink throughput of the terminal.
The following is a detailed description of how to control the first antenna and the second antenna to form the antenna array.
In the first case, the first antenna and the second antenna are controlled to form an antenna array based on the uplink transmitting capability currently required by the terminal.
In practical application, in some scenarios, the uplink transmitting capability required by the terminal is relatively large, so that the first antenna and the second antenna can be controlled to form an antenna array, and the formed antenna array is combined with a radio frequency circuit for transmitting radio frequency signals to meet the currently required uplink transmitting capability of the terminal.
Based on this, in an embodiment, the control unit 22 is specifically configured to:
and when the uplink transmitting capacity currently required by the capacity information representation terminal meets a first preset condition, generating a first control instruction.
Here, that the uplink transmission capability currently required by the terminal meets the first preset condition may mean that the uplink transmission capability currently required by the terminal is greater than a capability threshold, and/or that the uplink transmission capability currently required by the terminal is greater than or equal to a downlink reception capability.
For example, table 1 is an illustration of a scene corresponding to the uplink transmission capability currently required by the terminal meeting the first preset condition, and as shown in table 1, taking a video scene as an example, if a bandwidth corresponding to a video currently uploaded by a user is greater than a bandwidth threshold, it indicates that the uplink transmission capability currently required by the terminal meets the first preset condition; and/or, if the bandwidth corresponding to the video currently uploaded by the user is greater than the bandwidth corresponding to the video currently downloaded by the user, it indicates that the uplink transmitting capability currently required by the terminal meets the first preset condition, so that the two antennas of the antenna unit 21 can be controlled by the control unit 22 to form the antenna array.
TABLE 1
In practical application, the reason that the first antenna can transmit radio frequency signals and can receive radio frequency signals in a master set mode is that the radio frequency circuit communicated with the first antenna has a transceiving function, and the reason that the second antenna can only receive radio frequency signals is that the radio frequency circuit communicated with the second antenna only has a transmitting function.
Based on this, in an embodiment, the first switch unit 23 is disposed in the path of the first antenna; the first switch unit 23 is specifically configured to:
and responding to the first control instruction, and switching the second path of antenna into the first path of antenna so as to enable the first path of antenna and the second path of antenna to form an antenna array, thereby meeting the uplink transmitting capability currently required by the terminal.

(2) The antenna ANT2 has a switch 1 in its path. When the terminal needs large uplink throughput and the current hardware configuration cannot be met, the switch 1 is turned to the position A, the hardware configuration mode is changed, the antenna ANT2 is connected with the TRX, the TRX is simultaneously connected with the antenna ANT1 and the antenna ANT2, the two antennas work as an integral antenna group, and communication is carried out by utilizing the overlapping performance of the antenna ANT1 and the antenna ANT 2. Wherein the distance between antenna ANT1 and antenna ANT2 is within one operating wavelength.
(3) Taking two antennas as LTE high-frequency antennas as an example, for the size of a common mobile terminal, the two antennas are placed at random and have a distance within one wavelength, so that the directional patterns of the two antennas can be ensured to be superposed.
(4) When the switch 1 is turned to the point B, the antenna ANT2 is switched on DRX, the antenna ANT1 is switched on TRX, and the two antennas are independent and work respectively.
(5) The embodiment of the invention includes, but is not limited to, two-path antenna transformation, and can also be transformation of multiple paths of antennas.

the control unit is used for determining the current required capability information of the terminal; when the uplink transmitting capacity currently required by the capacity information representation terminal meets a first preset condition, generating a first control instruction;
the switch 1 is used for responding to the first control instruction, switching the antenna ANT2 into the antenna ANT1 so as to enable the antenna ANT1 and the antenna ANT2 to form an antenna array to meet the currently required uplink transmitting capacity of the terminal; antenna ANT1 is a main set antenna, and antenna ANT2 is a diversity antenna.
And the switch 2 is used for switching on the antenna array and the radio frequency signal source so as to transmit the radio frequency signal. The switch 2 may be disposed at a position close to the signal source 1 or may be disposed at a position close to the antenna.
In practical application, after the two antennas of the antenna unit 21 form an antenna array, the antenna array transmits a radio frequency signal of a radio frequency signal source, and in order to achieve the maximum radiation direction, a phase parameter of the radio frequency signal transmitted by the antenna array may be adjusted.
Based on this, in an embodiment, the circuit further comprises:
and the phase shifter is used for adjusting the phase of the radio frequency signal transmitted by the second antenna after the first antenna and the second antenna form an antenna array so as to superpose the radio frequency signal transmitted by the second antenna and the radio frequency signal transmitted by the first antenna.
Here, the phase of the radio frequency signal transmitted by the second antenna is adjusted, so that the radio frequency signal transmitted by the second antenna is superimposed with the radio frequency signal transmitted by the first antenna, and the superimposed radio frequency signal may correspond to the maximum radiation direction in the antenna pattern, thereby ensuring that the radio frequency signal is aligned with the base station.
Fig. 5 is a schematic diagram of a specific structure of the antenna switching circuit, and as shown in fig. 5, the antenna switching circuit includes: antenna ANT1, antenna ANT2, switch 1, control unit (not shown in fig. 5), signal source 1, phase shifter 1; wherein the content of the first and second substances,

the control unit corresponds to the control unit 22;
the switch 1 corresponds to the first switching unit 23;

The phase shifter 1 is configured to, after the antenna ANT1 and the antenna ANT2 form an antenna array, adjust a phase of a radio frequency signal transmitted by the antenna ANT2, so that the radio frequency signal transmitted by the antenna ANT1 and the radio frequency signal transmitted by the antenna ANT2 are superimposed, and the superimposed radio frequency signal may correspond to a maximum radiation direction in an antenna directional diagram, thereby ensuring that the radio frequency signal is aligned to a base station, and further improving uplink throughput.
It should be noted that, here, a phase shifter 1 may be added in the link of the antenna ANT2 to adjust the phase of the radio frequency signal transmitted through the antenna ANT2 to a proper phase, so as to ensure that the maximum radiation direction of the antenna pattern corresponding to the radio frequency signal superimposed by the antenna ANT1 and the antenna ANT2 can be aligned to the base station, thereby ensuring the maximization of the uplink transmission performance.
In practical application, as a preferred embodiment, in order to ensure that the maximum radiation direction of an antenna pattern corresponding to a radio frequency signal superimposed by two antennas can be aligned to a base station, the distance between the first antenna and the second antenna in the electronic device may be within one wavelength.
Based on this, in one embodiment, the distance between the first antenna and the second antenna is within one wavelength.
For example, taking the two antennas as LTE high-frequency antennas as an example, the two antennas may be placed at any position of an electronic device such as a mobile terminal, and if the distance between the first antenna and the second antenna is within one wavelength, it can be ensured that the effect of superimposing the directional patterns of the two antennas is optimal.
And in the second situation, the first path of antenna and the second path of antenna are controlled to form an antenna array based on the downlink receiving capability currently required by the terminal.

For example, table 2 indicates that the downlink receiving capability currently required by the terminal meets a scene corresponding to a second preset condition, and as shown in table 2, taking a video scene as an example, if a bandwidth corresponding to a video currently downloaded by a user is greater than a bandwidth threshold, it indicates that the downlink receiving capability currently required by the terminal meets the second preset condition; and/or, if the bandwidth corresponding to the video currently downloaded by the user is greater than the bandwidth corresponding to the video currently uploaded by the user, it indicates that the downlink receiving capability currently required by the terminal meets the second preset condition, so that the two antennas of the antenna unit 21 can be controlled by the control unit 22 to form an antenna array.
