Detailed Description

Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, like numbers in different drawings represent the same or similar elements unless otherwise indicated. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present invention. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the invention, as detailed in the appended claims.

In order to solve technical problems in the related art, the present disclosure provides an antenna switching apparatus, including: the antenna comprises a plurality of antennas, at least one transceiving module, at least one receiving module and at least one connecting part. The first side of the connecting part is connected with the antenna, and the second side of the connecting part is connected with the transceiving module and/or the receiving module; the connecting part comprises a plurality of connecting passages, and the connecting part is used for communicating or switching the connecting passages under the control signal so as to enable any antenna to be connected with the transceiving module or the receiving module through the connecting passages. In the present disclosure, by switching or communicating different connection paths of the connection portion, connection between any one of the antennas and the transceiver module or the receiver module is realized, thereby realizing multi-antenna switching. In addition, in the present embodiment, by adjusting the connection path, the receiving module can also have a corresponding connectable antenna, and the antenna switching is performed while transmitting and receiving signals, and the received signals of the antenna are not affected.

In an exemplary embodiment, the antenna switching apparatus of this embodiment is applied to a terminal device, where the terminal device may be an electronic device with signal transceiving function, such as a mobile phone, a tablet computer, a notebook computer, and a smart watch.

As shown in fig. 1, the antenna switching apparatus includes: a plurality of antennas 10, at least one transceiver module 20, at least one receiver module 30, and at least one connection 40.

The antenna 10 may be, for example, a metal conductor radiating part located inside or on a frame of the terminal device. The transceiver module 20 may be, for example, an antenna matching circuit for cooperating with an antenna to implement the functions of the antenna for transceiving (receiving and transmitting) signals. The receiving module 30 may be, for example, an antenna matching circuit for cooperating with an antenna to realize a function of receiving signals by the antenna.

In this embodiment, the number of the antennas 10 may be set according to actual requirements, for example, 4 or 6.

The number of the transceiver modules 20 can be set according to the communication function requirement of the terminal equipment. For example, when the communication signal pattern of the terminal device has the requirements of 4G LTE and 5G NR SA, a transceiver module may be provided. For another example, when the communication signal mode of the terminal device has the requirements of 4G LTE, 5G NR SA, and 5G NR NSA, two transceiver modules may be provided, where one transceiver module realizes the signal transceiving function in the 4G LTE and 5G NR SA modes, and the other transceiver module may cooperate to realize the signal transceiving function in the 5G NR NSA mode.

The number of receiving modules 30 can be set to suit the number of antennas and the number of transceiving modules. Each antenna should be capable of being connected with a transceiver module or a receiving module to achieve the functions of transmitting and receiving signals. For example, when the number of the antennas is 4 and the number of the transceiver modules set according to the required communication function is 1, 3 receiver modules may be set; if the number of the transceiver modules set according to the required communication function is 2, 2 receiver modules can be set. Similarly, when the number of the antennas is 6 and the number of the transceiver modules is 2, 4 receiver modules can be provided.

In the present embodiment, as shown in fig. 1, the connecting portion 40 includes a first side and a second side opposite to each other. The first side of the connection portion 40 is connected to the antenna 10, and the second side of the connection portion 40 is connected to the transceiver module 20 and/or the receiver module 30. The connection portion 40 includes a plurality of connection paths, and the connection portion 40 is configured to communicate or switch the connection paths under a control signal so that the corresponding antenna 10 is connected to the transceiver module 20 or the receiver module 30 through the connection paths.

For example, in the initial state, the first connection path of the connection unit is turned on according to the control signal, and the first antenna may be connected to the transceiver module through the first connection path. When the processor of the terminal equipment issues a switching control signal, the first connection path can be switched to the second connection path, so that the first antenna is connected with the receiving module. The second antenna connected with the receiving module in the initial state can be switched to be connected with the receiving and transmitting module.

In one example, the connection portion may be, for example, a circuit board in which a plurality of connection paths are integrated, and a control switch is provided on each connection path. The control switch can be connected with the processor of the terminal equipment in a communication mode, and the corresponding connection path is controlled to be communicated under the control signal of the processor.

In another example, the connection 40 can also be a multi-pole, multi-throw switch, for example.

In an exemplary embodiment, as shown in fig. 1, the plurality of antennas 10 includes at least two groups, and each group includes at least two antennas 10. One connection 40 for each group. Here, the phrase "one connection portion 40 corresponds to each group" means that: at least two antennas 10 in each group can be connected to the corresponding transceiver module 20 or receiver module 30 through a connection portion 40.

Within each group, at least two antennas 10 are connected to the corresponding connection portions 40, respectively, and the connection portion 40 corresponding to each group and the connection portions 40 corresponding to the other groups can be connected by a preset line.

In one example, as shown in fig. 1, 6 antennas are provided in the present embodiment. ANT1 antenna and ANT2 antenna may form a first packet, ANT3 antenna and ANT4 antenna may form a second packet, and ANT5 antenna and ANT6 antenna may form a third packet. One connection portion 40 is associated with each group, and taking the example that the connection portions 40 are configured as three-pole three-throw switches, a first group corresponds to a first connection portion (first switch), a second group corresponds to a second connection portion (second switch), and a third group corresponds to a third connection portion (third switch).

An ANT1 antenna is connected to the first port (port a) of the first switch, and an ANT2 antenna is connected to the second port (port b) of the first switch. The third port (port c) of the first switch is connected to the fourth port (port d) of the second switch.

In one exemplary embodiment, still referring to fig. 1, a first side and a second side of each connection portion 40 are provided with a plurality of connection ports; the antenna 10 is connected to the connection port of the first side, and the transceiver module 20 or the receiver module 30 is connected to the connection port of the second side.

Two antennas in one group occupy two connection ports on the first side of the corresponding connection part, and the rest connection ports on the first side are connected with the connection parts in the rest group. For example, as shown in fig. 2, within the first packet, ANT1 antenna and ANT2 antenna occupy the first port and the second port of the first connection. The remaining third ports are connected to the second connection portions corresponding to the second packet.

Two connecting ports of the second side of the corresponding connecting part of one group are connected with the transceiving module and/or the receiving module, and the rest connecting ports of the second side of the corresponding connecting part are connected with the connecting parts in the rest other group. For example, as shown in fig. 2, in the first connection portion corresponding to the first packet, the fourth port is connected to the first transceiver module, and the fifth port is connected to the first receiver module. The remaining sixth ports are connected to the third connection portions corresponding to the third partitions.

Under the control signal, in each connection part, the connection port of the first side is connected with any connection port of the second side to communicate with the corresponding connection passage. For example, as shown in fig. 2, in the first packet, the first port and the fourth port of the first connection portion are connected to communicate with a connection path; the second port is connected to the fifth port and communicates with the other connection passage.

It is understood that the connection ports on the first side are not occupied when being connected with the connection ports on the second side to communicate the connection passage.

In one exemplary embodiment, as shown in fig. 1-5, the plurality of antennas 10 includes a first group, a second group, and a third group, each of the first group, the second group, and the third group including two antennas. The connection portions 40 include first connection portions, second connection portions, and third connection portions, the first grouping corresponding to the first connection portions, the second grouping corresponding to the second connection portions, and the third grouping corresponding to the third connection portions. The transceiver module 20 includes a first transceiver module and a second transceiver module. The receiving module 30 includes a first receiving module, a second receiving module, a third receiving module and a fourth receiving module.

The first transceiving module or the second transceiving module is connected with any antenna through the connecting part. Each connection portion 40 has three connection ports (port a, port b, port c) on a first side and three connection ports (port d, port e, port f) on a second side.

In an exemplary embodiment, as shown in fig. 1-5, the connection 40 is a three-pole, three-throw switch, for example. As shown in fig. 1, 6 antennas are provided in this embodiment.

There is one connection 40 per group, the first connection being, for example, a first switch, the second connection being, for example, a second switch, and the third connection being, for example, a third switch.

Within the first group, one antenna (ANT1 antenna) is connected to the first port (port a) of the first connection (first switch) and the other antenna (ANT2 antenna) is connected to the second port (port b) of the first connection.

In an exemplary embodiment, the present disclosure further provides a terminal device, which includes a processor and the antenna switching apparatus of the foregoing embodiment, and at least one transceiver module and at least one receiver module are connected to the processor. The processor may be, for example, a signal processor.

In an exemplary embodiment, the present disclosure further provides an antenna switching method, which is applied to the terminal device of the foregoing embodiment. As shown in fig. 6, the method of this embodiment specifically includes the following steps:

and S110, determining a preset number of antennas meeting set conditions in the plurality of antennas.

And S120, determining the connecting parts which are suitable for the preset number of antennas and the connecting paths which meet the conditions in the connecting parts.

S130, responding to the initial state, and communicating a preset number of initial connecting passages; and each antenna in the preset number of antennas is connected with the initial transceiving module or the initial receiving module through the corresponding initial connecting passage.

And S140, responding to the switching state, switching the initial connecting paths corresponding to the antennas to be switched among the antennas with the preset number, connecting the target connecting paths of the target antennas, and connecting the target antennas with the target transceiving module or the target receiving module.

In step S110, the setting conditions may be, for example: under the current environment or the gesture of the user using the terminal device, the antenna with better signal transmitting and receiving performance is transmitted and received. The processor may be based on: the stored antenna test data, the environmental conditions when the performance is good, the antenna setting position and other factors determine a plurality of antennas meeting the set conditions.

In the embodiment shown in fig. 1, the present embodiment is provided with 6 antennas.

In the first mode, the predetermined number of antennas are part of the plurality of antennas. The first mode may be in a 4G LTE or 5G NR SA operating mode, for example, in a 4G frequency band (B1), selecting 4 antennas with better performance, which are: ANT1 antenna, ANT2 antenna, ANT3 antenna, and ANT4 antenna.

In the second mode, the predetermined number of antennas is all of the plurality of antennas. The second mode may be a 5G NR NSA mode.

In step S120, a connection line that can connect the antenna to the transceiver module or the receiver module is determined. The method specifically comprises the following steps:

s1201, determining a group where a preset number of antennas are located.

In combination with the above-mentioned embodiments of the antenna switching apparatus, the plurality of antennas may include different groups, each group including two antennas.

For example, in connection with the embodiment shown in fig. 1, ANT1 antenna and ANT2 antenna form a first packet and ANT3 antenna and ANT4 antenna form a second packet. The ANT1 antenna and ANT2 antenna selected in step S110 are in the first group and ANT3 antenna and ANT4 antenna are in the second group.

S1202, the connection part corresponding to the group is determined, and the initial connection path meeting the condition in the connection part is determined.

The term "initial connection path satisfying the condition" means that the antenna can be connected to the transmitter module or the receiver module.

In connection with the above-described embodiment of the antenna switching apparatus, there is one connection portion for each group. For example, as shown in fig. 1, the connection section is a three-pole three-throw switch, the first packet pair corresponds to the first connection section (first switch), and the second packet pair corresponds to the second connection section (second switch).

An ANT1 antenna is connected to the first port (port a) of the first switch, and an ANT2 antenna is connected to the second port (port b) of the first switch. The fourth port (port d) of the first switch is connected with the first transceiving module, and the fifth port (port e) of the first switch is connected with the first receiving module. The third port (port c) of the first switch is connected to the fourth port (port d) of the second switch, and the sixth port (port f) of the first switch is connected to the first port (port a) of the third switch.

The ANT3 antenna is connected to the second port (port b) of the second switch, and the ANT4 antenna is connected to the third port (port c) of the second switch. The first port (port a) of the second switch is connected with the fourth port (port d) of the third switch, the fifth port (port e) of the second switch is connected with the second transceiver module, and the sixth port (port f) of the second switch is connected with the second receiver module.

The ANT5 antenna is connected to the second port (port b) of the third switch, and the ANT6 antenna is connected to the third port (port c) of the third connection unit. The fifth port (port e) of the third switch is connected to the third receiving module, and the sixth port (port f) of the third connecting portion is connected to the fourth receiving module.

In this step, as shown in fig. 2, the initial connection path satisfying the condition includes: in the first switch, the port a and the port d are connected, and in the first switch, the port b and the port e are connected. And, in the second switch, a connection path between the port b and the port e, and a connection path between the port c and the port f.

In step S130, the initial state refers to the connection state before the antenna switching, and may be in the 4G mode or the 5G mode. In this embodiment, the 4G LTE mode is taken as an example.

In connection with step S120, the determined initial connection paths are connected, and as shown in fig. 2, the port a is connected to the port d, and the port b is connected to the port e in the first switch. In the second switch, port b is connected to port e, and port c is connected to port f.

Therefore, in the initial state, as shown in fig. 2, the working path of the 4G LTE mode (transmitting and receiving 4G frequency band signals) is as follows:

(1) ANT1 antenna-first switch-first transceiver module-signal processor;

(2) ANT2 antenna-first switch-first receiving module-signal processor;

(3) ANT3 antenna-second switch-second transceiver module-signal processor;

(4) ANT4 antenna-second switch-second receiving module-signal processor.

In step S140, the switching state may be, for example, a state in which the processor determines that the antenna needs to be switched according to the current environment or the gesture of the user currently using the terminal device. The method specifically comprises the following steps:

s1401, the receiving and sending module connected under the initial state of the antenna to be switched is determined as a target receiving and sending module.

The antenna to be switched may be, for example, an antenna connected to the transceiver module in an initial state among a preset number of antennas. The processor can determine the antenna to be switched according to the signal transceiving condition of the current transceiving module.

For example, when the initial state is as shown in fig. 2, the antenna to be switched may be an ANT1 antenna, for example. The target transceiver module is the first transceiver module.

And S1402, determining a target antenna.

The target antenna may be any antenna except the antenna to be switched among a preset number of antennas. The target antenna can be grouped with the antenna to be switched or can be grouped with the antenna to be switched.

For example, the antenna to be switched is an ANT1 antenna, and the predetermined grouping in which the antenna is located is the first grouping. The target antenna may be an ANT2 antenna of the same group or an ANT4 antenna of a different group.

In the embodiment shown in fig. 2 in the initial state, the target antenna is an ANT4 antenna.

And S1403, communicating the target connection path, and adjusting the connection path in the connection part corresponding to the antenna to be switched so as to connect the target antenna with the target transceiving module.

The terminal device may be pre-stored with a table of correspondence between the antenna, the transceiver module or the receiver module, the connection path, and the signal mode (4G or 5G). The processor can directly acquire the information of other items according to any item in the corresponding relation table.

After determining the target transceiver module and the target antenna, the processor may determine a target connection path. The processor may issue a control signal to control the involved connection to switch the connection path.

In one example, as shown in fig. 2 to 3, in the 4G band, the antenna to be switched (ANT1 antenna) is switched with a target antenna (ANT4 antenna) of a different group. In this example, the initial state before switching is shown in fig. 2, and the state after switching is shown in fig. 3.

For example, the first transceiver module needs to switch the ANT1 antenna to the ANT4 antenna.

As shown in fig. 2, in the initial state of this example, the ANT1 antenna is connected to the first transceiver module through the first switch. The ANT4 antenna is connected to the second receiving module through the second switch. For the target antenna, the connection path before switching is: and the connection between the port c and the port e of the second switch.

As shown in fig. 3, in order to realize the connection between the target antenna (ANT4 antenna) and the target transceiver module (first transceiver module), the target connection path is: and the connection between the port c and the port d of the second switch. As is known from fig. 3 and the previous embodiments, the port d of the second switch is connected to the port c of the first switch.

In order to connect the target connection path with the first transceiving module through the first switch, the initial connection path of the antenna to be switched needs to be switched. As shown in fig. 2, the initial connection paths of the antenna to be switched are: and the port a and the port d of the first switch are connected.

As shown in fig. 3, the connection method of the connection path in the first switch is adjusted so that the port c in the first switch is connected to the port d of the first switch, thereby connecting the target antenna (ANT4 antenna) and the target transceiver module (first transceiver module).

S1404, connecting the antenna to be switched to the receiving module in the initial state of the target antenna.

When the antenna of the transceiver module is switched, the antenna of the transceiver module is also adaptively switched to the receiver module involved in the switching. That is, for the antenna to be switched and the target antenna, after switching, the target antenna is switched to the transceiver module of the antenna to be switched, and the antenna to be switched is switched to the receiver module of the target antenna.

In one example, as shown in fig. 2 to 3, in a scheme in which the antenna to be switched (ANT1 antenna) and the target antenna (ANT4 antenna) implement switching: the ANT1 antenna needs to be connected to the second receiving module that was originally connected to ANT 4. In this example, the initial state before switching is shown in fig. 2, and the state after switching is shown in fig. 3.

In step S1403, the connection method of the first switch is further adjusted to form a connection path through which the port a and the port f of the first switch are connected. As can be seen from fig. 3 and the foregoing embodiments, the port f of the first switch is connected to the port a of the third switch.

To connect the ANT1 antenna with the second receiving module, the third switch needs to connect the connection path between the port a and the port d. As can be seen from fig. 3, the port d of the third switch is connected to the port a of the second switch, so the second switch needs to communicate: the connection path of the port a and the port f. Therefore, the ANT1 antenna sequentially passes through the first switch, the third switch and the second switch to realize connection with the second receiving module.

In this example, the switched circuit connection may specifically refer to fig. 3, and after the antenna switching is performed, both the transceiver module and the receiving module related to this example may achieve normal operation.

In a specific embodiment, as shown in fig. 4 to 5, in the 5G NR NSA operation mode, for example, in the 4G band and the 5G band. The antenna to be switched can be switched with the antenna in the same group. In this embodiment, the initial state before switching is shown in fig. 4, and the state after switching is shown in fig. 5.

As shown in fig. 4, in the present embodiment, the operation paths in the initial state are as follows:

in the 4G LTE band (B3):

ANT 1-first switch-first transceiver module-signal processor;

ANT 2-first switch-first receiving module-signal processor;

ANT 3-second switch-second transceiver module-signal processor;

ANT 4-second switch-second receiving module-signal processor;

in the 5G band (N41):

ANT 3-second switch-second transceiver module-signal processor;

ANT 4-second switch-second receiving module-signal processor;

ANT5, third switch, third receiving module, signal processor;

ANT6 signal processor with three switches, four receiving modules

In one example, for the path of the 4G LTE frequency band, the first transceiver module that implements LTE signal transceiving may exchange an antenna with the first receiver module.

For example, as shown in fig. 5, the antenna to be switched (ANT1 antenna) is switched with the target antenna in the same group (ANT2 antenna).

In this example, the connection between the target antenna (ANT2 antenna) and the target transceiver module (first transceiver module) is implemented, and the target connection path is: and the connection path of the port b and the port d of the first switch.

Meanwhile, another connection path in the first switch is adjusted, and the adjusted connection path is as follows: the port a and the port e of the first switch are connected, so that the antenna to be switched (ANT1 antenna) is connected with the first receiving module.

In another example, for the path of the 5G band, the second transceiver module that implements 5G NR signal transceiving may exchange antennas with the second receiving module, the third receiving module, or the fourth receiving module.

For example, as shown in fig. 5, the antenna to be switched (ANT3 antenna) is switched with the target antenna in the same group (ANT4 antenna).

In this example, the connection between the target antenna (ANT4 antenna) and the target transceiver module (second transceiver module) is implemented, and the target connection path is: and the connection between the port c and the port e of the second switch.

Meanwhile, another connection path in the second switch is adjusted, and the adjusted connection path is as follows: the port b of the second switch is connected with the port f, so that the antenna to be switched (ANT3 antenna) is connected with the second receiving module.

Meanwhile, in this example, the NR signal may implement the round of the 1T4R signal, the SRS signal on the ANT3 antenna, the ANT4 antenna, the ANT5 antenna, and the ANT6 antenna. That is, the second transceiving module may automatically switch between the ANT3 antenna, the ANT4 antenna, the ANT5 antenna, and the ANT6 antenna, so that each antenna can periodically transmit signals.

The antenna switching method of this embodiment may switch the four antennas of the transmission signal in the case of receiving 4 × 4MIMO in a 4G LTE or 5G NR SA scenario. It is also possible to implement a four antenna switching of the NR transmit signal in the reception of 4 x 4MIMO in the context of an endec scenario (5GNR NSA). And the NR 1T4R signal and SRS signal in the endec scenario take turns.
