According to the current internet broadband access mode, the access modes can be classified into FTTH (fiber to the home), DSL (digital telephone line access), cable (Cable television line access), and Mobile (Mobile access, i.e. wireless CPE). The client front-end equipment is mobile signal access equipment for receiving mobile signals and transmitting the mobile signals by wireless WIFI signals, is equipment for converting high-speed 4G or 5G signals into WiFi signals, and can support a plurality of mobile terminals to access a network simultaneously. The embodiment of the application provides a client front-end device. As shown in fig. 1, the customer premises equipment includes an antenna group 110, radio frequency circuitry 120, switching circuitry 130, radio frequency processing circuitry 140, a housing, memory (which optionally includes one or more computer-readable storage media), a processor, a peripheral interface, an input/output (I/O) subsystem, and so forth. These components optionally communicate over one or more communication buses or signal lines. These components optionally communicate via one or more communication buses or signal lines.

Specifically, the antenna group 110 includes a plurality of transmitting antennas (e.g., B1, B2) for transmitting radio frequency signals in a predetermined frequency band. For example, the plurality of transmitting antennas may be 5G antennas, 4G antennas, wiFi antennas, bluetooth antennas, etc., and are used for correspondingly receiving and transmitting radio frequency signals of corresponding frequency bands. The number N of the transmitting antennas can be 2, 3, 4, 6, 8, 10 and the like, the plurality of transmitting antennas are uniformly arranged at intervals along the peripheral direction of the customer premises equipment, and the radiation surfaces of the plurality of transmitting antennas face different directions, so that the beam scanning range of each transmitting antenna can realize 360-degree omnidirectional coverage of the horizontal plane.

The switch circuit 130 is connected to the plurality of transmitting antennas, and the rf processing circuit 140 is connected to the rf circuit 120 and the switch circuit 130. The rf circuit 120 is configured to perform transceiving processing on a received rf signal, that is, the rf circuit 120 may support transceiving processing on an rf signal.

The rf circuit 120 is connected to multiple transmitting antennas through the switch circuit 130, and the switch circuit 130 can conduct the rf path between any of the reflecting antennas and the rf circuit 120 under the control of the rf processing circuit 140, that is, can selectively conduct the transmitting path where any of the transmitting antennas is located. For example, the rf circuit 120 may include a transceiver module supporting receiving and transmitting rf signals, a receiver module supporting receiving rf signals, and so on.

The rf processing circuit 140 may include an rf transceiver 141 and a baseband processor 142 to control transmission and reception of rf signals, and the like. In the present embodiment, the rf processing circuit 140 may be configured to control the first transmitting antenna to transmit the rf signal; if the condition of switching to use a second transmitting antenna is met, enabling a first switching mode and a second switching mode, wherein a first switching instruction is generated in the first switching mode, and a second switching instruction is generated in the second switching mode; generating a target switching instruction according to the first switching instruction and/or the second switching instruction; controlling the switch circuit 130 to switch the first transmitting antenna to the second transmitting antenna according to the target switching instruction; wherein the first transmitting antenna and the second transmitting antenna are one of the plurality of transmitting antennas.

Those skilled in the art will appreciate that the customer premises equipment illustrated in fig. 1 is not limiting of customer premises equipment and may include more or fewer components than illustrated, or some components may be combined, or a different arrangement of components. The various components shown in fig. 1 are implemented in hardware, software, or a combination of both hardware and software, including one or more signal processing and/or application specific integrated circuits.

Fig. 2 is a flowchart of an antenna switching method according to an embodiment. The antenna switching method in this embodiment is described by taking the example of the method running on the client front-end device in fig. 1. As shown in fig. 2, the antenna switching method includes steps 202 to 208.

Step 202, controlling the first transmitting antenna to transmit the radio frequency signal.

The first transmitting antenna can be understood as any one of a plurality of transmitting antennas. The customer premises equipment can conduct a transmission path where the first transmission antenna is located, so that the first transmission antenna is in a working state, and further transmits radio frequency signals. Specifically, the customer premises equipment may control the switch circuit 130 to connect the radio frequency path between the first transmitting antenna and the transceiver circuit, and further connect the transmitting path of the first transmitting antenna.

And step 204, if the condition of switching to use the second transmitting antenna is met, enabling a first switching mode and a second switching mode, wherein a first switching instruction is generated in the first switching mode, and a second switching instruction is generated in the second switching mode.

The client front-end device may determine whether a condition for switching to use of the second transmission antenna is satisfied according to a transmission performance of the current first transmission antenna. The Transmission performance may be determined according to a Transmission Power on a Transmission channel where the first transmitting antenna is located, for example, a Transmission Power Gain adjustment value (TX Automatic Gain Control, TXAGC) may be understood as a characteristic value of Power, and a number of times of reaching a Maximum Transmission Power Level (MTPL) is reached. If the number of times the maximum transmit power level is reached exceeds a predetermined value, it is determined that a condition for switching to use of the second transmit antenna is satisfied.

In one embodiment, the client front-end device includes multiple receiving antennas, for example, N receiving antennas. The customer premise equipment can select K receiving antennas from the multiple receiving antennas to form the multiple receiving antenna group 110, where K is greater than or equal to 2 and less than or equal to N, and N is greater than or equal to 4. The client front-end device may also determine whether a condition for switching to use the second transmit antenna is satisfied according to network information of the radio frequency signal currently received by the receive antenna group 110. The network information may include, among other things, raw and processed information associated with wireless performance metrics of the received radio frequency signal, such as received power, reference signal received quality, received signal strength indication, signal-to-noise ratio, and so on. For example, the received power of the signal is taken as the network information as an example for explanation. And when the reference signal receiving power is smaller than a preset threshold value, the condition of switching to the second transmitting antenna is considered to be met.

In one embodiment, the ue may set the start interval periods of the first switching mode and the second switching mode, and when the respective start interval periods are satisfied, the ue considers that the condition for switching to use the second transmitting antenna is satisfied. Illustratively, the period of the start interval of the first switching pattern is 2 seconds, and the period of the start of the switching pattern of the second antenna is 3s. That is, the first switching mode is enabled every 2s, and the second switching mode is enabled every 3s.

The first switching mode can be understood as a passive switching mode, and the setting of the passive switching mode can be determined according to the requirement of switching the transmitting antenna. That is, while the first transmit antenna transmits the rf signal to the base station, the baseband processor 142 in the cpe may control the multiple receive antenna groups 110 to receive the rf signal from the base station one by one, and generate the first switch instruction according to the network information of the received rf signal.

The second switching mode may be understood as an active switching mode. When the customer premises equipment controls the first transmitting antenna to transmit the radio frequency signal, the radio frequency transceiver 141 of the customer premises equipment judges the state of the transmitting antenna according to the number of times that the power information on the transmitting channel reaches the MTPL to generate a second switching instruction.

In the embodiment of the present application, the starting time of the first switching mode and the starting time of the second switching mode may be the same or different.

And step 206, generating a target switching instruction according to the first switching instruction and/or the second switching instruction.

The client front-end device may generate the target switching instruction according to a timing at which the first switching instruction and the second switching instruction are received. Specifically, if the time when the client front-end device receives the first switching instruction is the same as the time when the client front-end device receives the second switching instruction, the target switching instruction may be generated according to the first switching instruction and the second switching instruction. If the client front-end device receives a difference between the first switching instruction and the second switching instruction, the target switching instruction may be generated according to the first switching instruction or the second switching instruction. For example, if a first handover instruction is received first, the first handover instruction may be used as the target handover instruction; if a second switching instruction is received first, the second switching instruction may be used as the target switching instruction. It should be noted that, receiving the first switching command first may be understood as receiving the first switching command earlier than receiving the second switching command in the same switching cycle, or after the first switching mode and the second switching mode are started.

And 208, controlling the switch circuit to switch the first transmitting antenna to a second transmitting antenna according to the target switching instruction, wherein the second transmitting antenna is one target transmitting antenna of the plurality of transmitting antennas.

The pre-client device may pre-store a correspondence between the target switching command and the control logic of the switch circuit 130, a correspondence between the first switching command and the control logic of the switch circuit 130, a correspondence between the second switching command and the control logic of the switch circuit 130, and a correspondence between each terminal of the switch circuit 130 and each transmitting antenna. Illustratively, if the transmit antennas include transmit antenna 1, transmit antenna 2, \8230, transmit antenna n, then the switch circuit 130 may be an SPnT switch. That is, the single terminal of the SPnT switch is connected to the transceiver circuit, and the n selection terminals of the SPnT switch are connected to the n transmitting antennas in a one-to-one correspondence. And the target switching instruction is used for conducting a path between the nth selection end and the single terminal of the SPnT switch. Specifically, the target switching command may be identified by a binary value, for example, 001 is used to identify a path between the first selection terminal and the single terminal of the SPnT switch, and 010 is used to identify a path between the second selection terminal and the single terminal of the SPnT switch. If the switch circuit 130 can be an SPDT switch, its corresponding target switching command can also be identified by high/low level information. For example, a high level is used to identify the path between the first selection terminal and the single terminal of the conducting SPDT switch, and a low level is used to identify the path between the second selection terminal and the single terminal of the conducting SPDT switch.

The identification manner and the identification meaning of the first switching instruction and the second switching instruction (i.e. the control logic of the switch circuit 130) are the same as the identification manner and the identification meaning of the target switching instruction. Optionally, the corresponding relationship between the first switching instruction and the control logic of the switch circuit 130, and the corresponding relationship between the second switching instruction and the control logic of the switch circuit 130 may also be set differently. In the embodiment of the present application, the identification manners of the first handover command, the second handover command, and the target handover command are not further limited.

The customer premises equipment may control the switch circuit 130 to switch the first transmitting antenna to the second transmitting antenna, i.e. the target receiving antenna, according to the target switching instruction, so as to implement switching control between the transmitting antennas.

According to the antenna switching method, the first transmitting antenna can be controlled to transmit the radio frequency signal, if the condition of switching to the second transmitting antenna is met, the first switching mode and the second switching mode are started, and the target switching instruction is generated according to the first switching instruction and/or the second switching instruction; and controlling the switch circuit 130 to switch the first transmitting antenna to the second transmitting antenna according to the target switching instruction. According to the method, the client front-end device can obtain the first switching instruction and the second switching instruction, namely can receive the dual logic control signals (the first switching instruction and the second switching instruction), and outputs the target switching instruction after the received first switching instruction and the second switching instruction are processed in a negotiation mode, so that the use scenes (based on the first switching mode and the second switching mode) for switching the transmitting antenna are enriched, the good communication state is ensured, and the coverage range and the user experience of the transmitting antenna during use are improved.

As shown in fig. 3, in one embodiment, the first switching mode is enabled, specifically including step 302 to step 308.

Step 302, based on the first transmitting antenna, the baseband processor obtains network information of the radio frequency signals respectively measured by the multiple receiving antenna groups.

In one embodiment, the customer premises equipment may include multiple receiving antennas, for example, N receiving antennas, where the receiving antennas may be a 5G antenna, a 4G antenna, a WiFi antenna, a bluetooth antenna, and the like, and are used for correspondingly transceiving radio frequency signals in corresponding frequency bands. The number N of the receiving antennas may be 2, 3, 4, 6, 8, 10, etc. to meet the communication requirement of the customer premises equipment. The radiation surfaces of the N receiving antennas face at least three different directions. It is also understood that each receiving antenna has a radiating plane, which is understood to be the plane in which the radiator for radiating radio frequency signals of the receiving antenna is located. The radiation surfaces of the receiving antennas are different in the facing direction, and the corresponding receiving antennas are different in the beam scanning range and the incoming wave direction. The N receiving antennas are respectively arranged at different positions of the client front-end equipment, so that the beam scanning range of each receiving antenna can realize 360-degree omnidirectional coverage of a horizontal plane. The customer premise equipment can "directionally" cater to "the downlink incoming wave direction of the base station by selecting K antennas as the receiving antenna group 110 from the N receiving antennas to complete the reception of the radio frequency signal, wherein K is less than or equal to N and is greater than or equal to 2. Specifically, the rf processing circuit 140 may configure the number K of receiving antennas in the receiving antenna group 110 according to a Multiple Input Multiple Output (MIMO) technology that can be supported by the customer premises equipment, and configure N receiving antennas into Multiple receiving antenna groups 110 according to a preset rule, so that each receiving antenna group 110 includes K receiving antennas. The K receiving antennas in the receiving antenna group 110 have at least two sequentially adjacent radiation surfaces facing different directions. Illustratively, when the client front end device supports 2 × 2mimo, its receive antenna set 110 may include 2 receive antennas, and when the client front end device supports 4 × 4mimo, its receive antenna set 110 may include 4 receive antennas. In the embodiments of the present application, N =8,k =4 is exemplified.

The client front-end device may sequentially control and conduct the radio frequency path between each receiving antenna group 110 and the radio frequency processing circuit 140, so that each receiving antenna group 110 is in an operating state, and further, network information of the radio frequency signal received by each receiving antenna group 110 is correspondingly measured.

And step 304, determining a target receiving antenna group according to a plurality of network information.

In one embodiment, the received power of the signal is described by taking the network information as an example. That is, the client front-end device may obtain multiple reference signal received powers corresponding to multiple receive antenna groups 110, and obtain a maximum value of the multiple reference signal received powers, so as to use the maximum value as target network information, where the receive antenna group 110 corresponding to the target network information is the target receive antenna group 110.

Step 306, controlling the target receiving antenna group to receive the radio frequency signal, and obtaining an incoming wave direction of the target receiving antenna group receiving the radio frequency signal.

Each receiving antenna and each transmitting antenna carry identification information for representing the radiation surface of each antenna. Specifically, the step of acquiring the incoming wave direction of the radio frequency signal received by the target receiving antenna group 110 includes acquiring identification information of each receiving antenna in the target receiving antenna group 110, and acquiring the incoming wave direction of the radio frequency signal according to the identification information.

As shown in fig. 4a and 4b, in the embodiment of the present application, an example of eight receiving antennas and two transmitting antennas is described. In one embodiment, the rf system further includes a substrate. The substrate may be understood as a circuit board, e.g. a PCB board, an FPC board, etc., for carrying the rf circuit 120, the switch circuit 130, the rf processing circuit 140. The receiving antennas A1, A4 have a radiation surface 1, the receiving antennas A6, A7 have a radiation surface 2, the receiving antennas A2, A3 have a radiation surface 3, the receiving antennas A5, A8 have a radiation surface 4, the transmitting antenna B1 has a radiation surface 5, and the transmitting antenna B2 has a radiation surface 6. Illustratively, radiating surfaces 1,2, 3, 4, 5, 6 may be identified by 001, 002, 003, 004, 005, 006, respectively. That is, the identification information of each receiving antenna and each transmitting antenna in the embodiment of the present application may be used to indicate the incoming wave direction information, that is, the azimuth angle range, corresponding to each antenna radiation surface.

The transmitting antenna B1 and the receiving antennas A1, A4, A6, and A7 are located on a first side of the substrate 150, and the transmitting antenna B2 and the receiving antennas A2, A3, A5, and A8 are located on a second side of the substrate 150. Specifically, the transmitting antenna B1 has a fifth radiation surface located at the middle position between the antenna pair 1 and the antenna pair 4, and the transmitting antenna B2 has a sixth radiation surface located at the middle position between the antenna pair 2 and the antenna pair 3.

Specifically, a coordinate system may be constructed in the customer premises equipment, wherein a plane where the substrate 150 is located may be taken as an XZ plane of the coordinate system, a length direction of the substrate may be taken as an X axis, a width direction of the substrate, that is, a height direction of the customer premises equipment may be taken as a Z axis, and a straight line perpendicular to the XZ plane may be taken as a Y axis of the coordinate system. The direction of the radiation plane of the receiving antenna on the first side of the substrate includes a first direction and a second direction, the azimuth angle range corresponding to the first direction is defined as 0-90 °, the azimuth angle range corresponding to the second direction is 90-180 °, and the corresponding azimuth angle range of the transmitting antenna B1 on the first side of the substrate is 0-180 °. The direction of the radiation surface of the receiving antenna positioned on the second side of the substrate comprises a third direction and a fourth direction, the azimuth angle range corresponding to the third direction is defined to be 180-270 degrees, and the azimuth angle range corresponding to the fourth direction is 270-360 degrees; the corresponding azimuth angle of the transmitting antenna B2 located at the second side of the substrate is in the range of 180-360 °.

Step 308, generating the first switching instruction according to the incoming wave direction, where the first switching instruction is used to instruct the switch circuit to switch the first transmitting antenna to the second transmitting antenna.

The ue may construct a mapping relationship between the incoming wave direction of each receiving antenna group 110 and the matching first switching instruction in advance. Specifically, the first transmitting antenna is taken as the transmitting antenna B1 for example. Specifically, if the receiving antenna group 110 is the receiving antenna group 110 (A1, A4, A6, A7), the azimuth angle range of the corresponding incoming wave direction is 0 to 180 °, and the second transmitting antenna matched with the receiving antenna group is the transmitting antenna B1 with the identification information of 005, the corresponding first switching instruction is a high-level signal; if the receiving antenna set 110 is the receiving antenna set 110 (A2, A3, A4, A8), the azimuth angle range of the corresponding incoming wave direction is 180-360 °, the second transmitting antenna matched with the receiving antenna set is the transmitting antenna B2 with the identification information of 006, and the corresponding first switching command is a low level signal; if the receiving antenna set 110 is the receiving antenna set 110 (A4, A6, A7, A2), the azimuth angle range of the corresponding incoming wave direction is 0-270 °, the second transmitting antenna matched with the receiving antenna set is the transmitting antenna B2 with the identification information of 006, and the corresponding first switching command is a low level signal. Wherein, the high level signal is used to control the switch circuit 130 to turn on the path between the selection end of the transmitting antenna B1 and the single terminal of the switch circuit 130; the low level signal is used to control the switch circuit 130 to turn on a path connecting the selection terminal of the transmitting antenna B2 and the single terminal of the switch circuit 130.

As shown in FIG. 5, in one embodiment, the second switching mode is enabled, including steps 502-504. Wherein, the first and the second end of the pipe are connected with each other,

step 502, the radio frequency transceiver obtains the number of times that the power information of the first transmit antenna reaches the maximum transmit power level.

When the customer premises equipment controls the switch circuit 130 to turn on the transmission path where the first transmitting antenna is located, the rf transceiver 141 may determine the communication performance or the communication state of the first transmitting antenna according to the number of times that the power information on the transmission path, for example, the TXAGC, reaches the maximum transmission power level MTPL.

In step 504, the radio frequency transceiver generates a second switching instruction according to the number of times and the preset threshold, where the second switching instruction is used to instruct the switching circuit to switch to the second transmitting antenna.

The client front-end device may pre-store therein a standard number for evaluating its communication performance or communication status, which may be represented by a preset threshold. When the number of times that the TXAGC reaches the maximum transmission power level MTPL exceeds the preset threshold, it means that the transmission signal of the first transmission antenna cannot support the current communication service with the network side well at this time, and it needs to switch to another transmission antenna to try to improve the current transmission signal quality. Therefore, the rf transceiver 141 may generate the second switching command according to a comparison result of whether the number of times the TXAGC reaches the maximum transmission power level MTPL reaches the preset threshold. The second switching instruction is used to instruct the switching circuit 130 to switch to the second transmitting antenna. Specifically, the first transmitting antenna is taken as the transmitting antenna B1 for example. If the number of times that the TXAGC of the first transmitting antenna reaches the maximum transmitting power level MTPL does not reach the preset threshold, the transmitting antenna does not need to be switched, and the second transmitting antenna matched with the transmitting antenna is still the transmitting antenna B1, the corresponding second switching instruction high level signal is used for controlling the switch circuit 130 to turn on a path connecting the selection end of the transmitting antenna B1 and the single terminal of the switch circuit 130. If the number of times that the TXAGC reaches the maximum transmission power level MTPL reaches the preset threshold, the transmitting antenna needs to be switched, the second transmitting antenna matched with the TXAGC is the transmitting antenna B2, and the corresponding second switching instruction low-level signal is used for controlling the switch circuit 130 to conduct a path connecting the selection end of the transmitting antenna B2 and the single terminal of the switch circuit 130.

In the embodiment of the present application, the first switching command and the second switching command may be expressed in the same or different forms, for example, the high-low level signals may be the same or different, and the high-low level signals in the first switching command and the second switching command may be the same or different from the control logic of the switch circuit 130.

In one embodiment, in step 206, the step of generating the target handover instruction according to the first handover instruction or the second handover instruction specifically includes: and if the control logic unit module receives the first switching instruction and the second switching instruction in a time-sharing manner, generating a target switching instruction according to the first switching instruction or the second switching instruction. Specifically, the control logic unit module is connected to the rf transceiver 141, the baseband processor 142, and the switch circuit 130, and is configured to control the circuit switch to switch the first transmitting antenna to the second transmitting antenna according to the target switching instruction. The time-sharing reception may be understood as that the time when the control logic unit module receives the first switching instruction is different from the time when the control logic unit module receives the second switching instruction.

In one embodiment, the step of generating the target handover command according to the first handover command or the second handover command specifically includes a step of generating the target handover command by the control logic unit module according to a priority timing principle of receiving the first handover command and the second handover command in the handover period. If the control logic unit module receives the first switching instruction and the second switching instruction in a time-sharing manner, the target switching instruction is exemplarily generated according to the first switching instruction or the second switching instruction, and if the first switching instruction is received first, the first switching instruction can be used as the target switching instruction; if a second switching instruction is received first, the second switching instruction may be used as the target switching instruction. It should be noted that, receiving the first switching command first may be understood as receiving the first switching command earlier than receiving the second switching command in the same switching period, or after starting the first switching mode and the second switching mode.

In one embodiment, in step 206, the step of generating the target handover instruction according to the first handover instruction and the second handover instruction specifically includes: and if the control logic unit module receives the first switching instruction and the second switching instruction at the same time, generating a target switching instruction according to the first switching instruction and the second switching instruction.

In one embodiment, if the first switching instruction and the second switching instruction are the same, the target switching instruction is generated according to the first switching instruction or the second switching instruction. The first switching instruction is used for instructing the control circuit switch to switch the first transmitting antenna to the second transmitting antenna; the second switching instruction is used for instructing the control circuit switch to switch the first transmitting antenna to the second transmitting antenna. The first switching instruction and the second switching instruction are the same, and it can be understood that the second transmitting antenna corresponding to the first switching instruction is the same as the second transmitting antenna corresponding to the second switching instruction, that is, both of the first transmitting antenna and the second transmitting antenna are used for switching the first transmitting antenna to the transmitting antenna B1, or both of the first transmitting antenna and the second transmitting antenna are used for switching the first transmitting antenna to the transmitting antenna B2. It can also be understood that, if the control logic unit module receives the first switching instruction and the second switching instruction at the same time, and the first switching instruction and the second switching instruction are the same, the control logic unit module may use the first switching instruction or the second switching instruction as the target switching instruction.

In one embodiment, if the first switching instruction and the first switching instruction are different, the target switching instruction is generated according to the switching priorities of the first switching mode and the second switching mode. Specifically, the client front-end device may preset and store the switching priority of the first switching mode and the switching priority of the second switching mode, where the higher the priority level is, the higher the priority level of the target switching instruction correspondingly generated in the switching mode is. For example, when the priority of the first switching mode is higher than that of the second switching mode, if the control logic module receives the first switching instruction and the second switching instruction at the same time, the control logic module may generate a target switching instruction according to the first switching instruction to control the switch circuit 130 to switch the first transmitting antenna to the second transmitting antenna. The priority of the first switching mode and the priority of the second switching mode may be set by self-definition according to the network environment, the location environment, and other factors where the current client front-end device is located, or may be set by the operating system of the client front-end device.

In the antenna control method in the above embodiment, the control logic unit module may receive the first switching instruction sent by the baseband processor 142 and the second switching instruction sent by the radio frequency transceiver processor, that is, the control logic unit module may receive the dual logic control signal (the first switching instruction and the second switching instruction), and output the target switching instruction after performing "negotiation processing" on the received first switching instruction and the received second switching instruction signal, so that the usage scenarios (based on the first switching mode and based on the second switching mode) that can be used for switching the transmitting antenna are enriched, a good communication state is also ensured, and the coverage area and user experience of the transmitting antenna during usage are improved. In addition, when the first switching instruction and the second switching instruction received by the control logic unit module at the same time are different, the control logic unit module can also be understood as "contention resolution" by setting the switching priority, so as to avoid the occurrence of unstable switching caused by the difference (collision) between the first switching instruction and the second switching instruction, and further improve the stability of communication.

As shown in fig. 6, in one embodiment, the switching circuit 130 is controlled to switch the first transmitting antenna to the second transmitting antenna according to the target switching instruction, which includes steps 602 to 608. Wherein the content of the first and second substances,

step 602, obtaining pre-stored current first state information of the switch circuit; the first state information is used for indicating a transmission path where the switch unit conducts the first transmission antenna.

The first state information of the current switch circuit 130 is pre-recorded in the control logic unit module. The state information of the switch circuit 130 can be used to identify the switch state of the switch circuit 130. In the embodiment of the present application, the transmitting antenna includes a transmitting antenna B1 and a transmitting antenna B2, and the switching circuit 130 is an SPDT switch. The SPDT switch comprises a single terminal, a first selection end and a second selection end, wherein the single terminal is connected with the transceiving circuit, the first selection end is connected with the transmitting antenna B1, and the second selection end is connected with the transmitting antenna B2. The switch state of the switch circuit 130 may be used to indicate the conduction state of the single terminal and the first selection terminal or the second selection terminal. Specifically, the state information of the switch circuit 130 may be represented by a register value D, wherein the register value may be identified by 0 and 1. Exemplarily, when the register value is 1, it indicates that the single terminal of the current SPDT switch is conducted with the first selection terminal, that is, the transmission path of the transmitting antenna B1 is conducted; when the register value is 0, it indicates that the single terminal of the current SPDT switch is conducted with the second selection terminal, i.e., the transmission path of the transmission antenna B2 is conducted. Correspondingly, the register value 0 may be used to identify that the single terminal of the current SPDT switch is conducted with the first selection terminal, and the register value 1 may be used to identify that the single terminal of the current SPDT switch is conducted with the second selection terminal.

It should be noted that, if the number of the transmitting antennas is 3, 4 or more, the corresponding register values may be used for binary values or identified by other means, which is not further limited herein. For example, its register value may be set corresponding to the target switch instruction.

If the first transmitting antenna is the transmitting antenna B1, the customer premises equipment may correspondingly obtain the first state information of the switch circuit 130, that is, the register value 1; if the first transmitting antenna is the transmitting antenna B2, the customer premises equipment may correspondingly obtain the first state information of the switch circuit 130, that is, the register value 0.

Step 604, second state information of the switch circuit 130 corresponding to the target switching instruction is obtained.

The control logic unit module in the client front-end device may correspondingly obtain the second state information that the switch circuit 130 is to be switched to the second transmitting antenna according to the target switching instruction. For example, if the second transmitting antenna is the transmitting antenna B1, the second state information of the switch circuit 130 corresponding to the target switching instruction is the register value 1; if the second transmitting antenna is the transmitting antenna B2, the second state information of the switch circuit 130 corresponding to the target switching instruction is the register value 0.

Step 606, if the first state information is the same as the second state information, the first transmitting antenna is used as the second transmitting antenna, and the current state of the switch circuit is maintained.

Step 608, if the first status information is different from the second status information, controlling a switch circuit to switch the first transmitting antenna to a second transmitting antenna.

The control logic unit module may control the switch circuit 130 to perform corresponding switching according to the current first state information of the switch circuit 130 and the first state information to be switched. Specifically, if the first status information is the same as the second status information, the first transmitting antenna and the second transmitting antenna are determined to be the same transmitting antenna, and at this time, the control logic unit module may not perform corresponding switching control on the switch circuit 130, that is, maintain the current status of the switch circuit 130. And if the first state information is different from the second state information, determining that the first transmitting antenna and the second transmitting antenna are not the same transmitting antenna. If the first transmitting antenna is the transmitting antenna B1, at this time, the control logic unit module may control the switch circuit 130 to connect the paths of the single terminal and the second selecting terminal according to the target switching instruction, so as to connect the transmitting path of the transmitting antenna B2, and further switch the first transmitting antenna B1 to the second transmitting antenna B2.

In the antenna switching method in this embodiment, in the process of "negotiation" of the dual-transmit antenna decision mechanism, the control logic unit module is introduced, so that not only the first switching instruction and the second switching instruction output in the dual-transmit antenna switching mode are harmoniously converted into the target switching instruction to control the switching of the SPDT switch, but also the register of the control logic unit module can record the current state information of the SPDT switch, and the state information can be identified by the register value = D, so that repeated switching and useless switching can be avoided, the possibility of causing negative interference (for example, unstable communication) to the communication state of the client front-end device is eliminated, a good communication state is ensured, and the coverage range and user experience during use are improved.

In one embodiment, after the step of controlling the switch circuit to switch the first transmitting antenna to the second transmitting antenna, the antenna switching method further includes a step of updating the stored first state information according to the second state information. Specifically, the updated register value = MOD (D +1, 2) is registered as a new register value.

In this embodiment, the register value D of the switch circuit 130 is updated according to the second state information to provide a basis for the next switching of the transmitting antenna, so as to avoid repeated switching and useless switching of the transmitting antenna performed next time, thereby ensuring a good communication state.

In one embodiment, the antenna switching method further includes the step of initializing the switch circuit, and recording and storing the initialized state of the switch circuit, which is performed before the first switching mode and the second switching mode are enabled, so as to provide accurate state information of the switch circuit 130 for each switching of the transmitting antenna, thereby ensuring good communication state.

As shown in fig. 7, in one embodiment, after the step of controlling the switch circuit 130 to switch the first transmitting antenna to the second transmitting antenna according to the target switching instruction, the antenna switching control method includes steps 702 to 714.

Step 702, controlling a first transmitting antenna to transmit a radio frequency signal.

Step 704, if the condition for switching to use the second transmitting antenna is satisfied, the first switching mode and the second switching mode are enabled.

Step 706, generating a target switching instruction according to the first switching instruction and/or the second switching instruction.

Step 708, controlling a switch circuit to switch the first transmitting antenna to a second transmitting antenna according to the target switching instruction.

Here, steps 702 to 708 correspond to steps 202 to 208 in the foregoing embodiment one to one, and are not described herein again.

Step 710, after a preset time, detecting whether the transmission performance of the second transmitting antenna is better than that of the first transmitting antenna; if the transmission performance of the second transmitting antenna is not better than the transmission performance of the first transmitting antenna, step 712 is executed to control the switch circuit 130 to switch the second transmitting antenna to the first transmitting antenna; if the transmission performance of the second transmitting antenna is better than that of the first transmitting antenna, step 714 is executed to detect whether the condition for switching to use the second transmitting antenna is satisfied.

After the first transmitting antenna is switched to the second transmitting antenna, a window period T may be waited, where the window period T may be used as the preset time length, and it may be understood that after the second transmitting antenna is controlled to continuously transmit the radio frequency signal for the preset time length, whether the transmitting performance of the second transmitting antenna is better than the transmitting performance of the first transmitting antenna before switching is detected. Wherein the transmission performance may be determined by the number of times the TXAGC reaches a maximum transmit power level. If the TXAGC reaches the maximum transmission power level for a shorter time period, the TXAGC has better transmission performance. For example, a first number of times that the TXAGC of the first transmitting antenna reaches the maximum transmitting power level within the detection time duration may be obtained in advance, and if the number of times that the TXAGC of the second transmitting antenna reaches the maximum transmitting power level within the preset time duration is greater than the first number of times, step 712 is executed to control the switch circuit to switch the second transmitting antenna to the first transmitting antenna; the number of times its TXAGC reaches the maximum transmit power level is less than the first number of times, step 714 is performed to detect whether the condition for switching to use the second transmit antenna is met.

In the antenna switching method in the embodiment, a window stabilization period T is added after each switching, the transmission performance before and after one switching is detected after a window stabilizer, and whether the switching is successful is further determined, if the transmission performance after the switching to the second transmission antenna is superior to the performance of the first transmission antenna, the switching is considered to be meaningful, that is, meaningful for improving the communication quality, and the current switching can be maintained; otherwise, the switch circuit 130 is controlled to switch back to the first transmitting antenna, and the state information of the switch circuit 130 is restored to the state before switching.

It should be understood that although the various steps in the flowcharts of fig. 2, 3, 5-7 are shown in order as indicated by the arrows, the steps are not necessarily performed in order as indicated by the arrows. The steps are not performed in the exact order shown and described, and may be performed in other orders, unless explicitly stated otherwise.

That is, the device is a power amplifier module which integrates components such as a low noise amplifier, a power amplifier, a filter and the like in the same device, so that the integration level of the device can be improved, and the occupied space of the whole machine can be reduced.

In the embodiment of the present application, eight receiving antennas and two transmitting antennas are taken as an example for explanation.

As shown in FIG. 10, in one embodiment, the control logic unit module 143 includes a processing unit 1431 and a control unit 1432. The processing unit 1431 is connected to the rf transceiver 141 and the baseband processor 142, and is configured to generate a target handover command according to the first handover command and/or the second handover command. Specifically, the processing unit 1431 generates the target switching instruction according to the timing when the first switching instruction and the second switching instruction are received. If the processing unit 1431 receives the first switching instruction and the second switching instruction in a time-sharing manner, the target switching instruction is generated according to the first switching instruction or the second switching instruction. For example, if a first handover instruction is received first, the first handover instruction may be used as the target handover instruction; if a second switching instruction is received first, the second switching instruction may be used as the target switching instruction. It should be noted that, receiving the first switching command first may be understood as receiving the first switching command earlier than receiving the second switching command in the same switching period, or after starting the first switching mode and the second switching mode.

In addition, when the first switching instruction and the second switching instruction received by the control logic unit module 143 at the same time are different, the switching priority may also be understood as "contention resolution" by setting the switching priority, so as to avoid the occurrence of unstable switching caused by the difference (collision) between the first switching instruction and the second switching instruction, and further improve the stability of communication.

The processing unit 1431 is further configured to detect whether the transmission performance of the second transmitting antenna is better than the transmission performance of the first transmitting antenna when the duration reaches the preset duration; if not, the control unit 1432 is instructed to control the switch circuit 130 to switch the second transmitting antenna to the first transmitting antenna; if so, detecting whether a condition for switching to use of the second transmitting antenna is met.

After the first transmitting antenna is switched to the second transmitting antenna, the timing unit 1433 starts to be controlled to start timing, and when the recorded duration reaches the window period T, it is detected whether the transmitting performance of the second transmitting antenna is better than that of the first transmitting antenna before switching. Wherein the transmission performance may be determined by the number of times the TXAGC reaches a maximum transmit power level. If the transmission performance after the switching to the second transmitting antenna is superior to that of the first transmitting antenna, the switching is considered to be meaningful, namely, meaningful for improving the communication quality, and the current switching can be maintained; otherwise, the switch circuit 130 is controlled to switch back to the first transmitting antenna, and the state information of the switch circuit 130 is restored to the state before switching.

The state information of the switch circuit 130 can be used to identify the switch state of the switch circuit 130. Specifically, the state information of the switch circuit 130 may be represented by a register value D, wherein the register value may be identified by 0 and 1. If the first transmitting antenna is the transmitting antenna B1, the customer premises equipment may correspondingly obtain the first state information of the switch circuit 130, that is, the register value 1; if the first transmitting antenna is the transmitting antenna B2, the customer premises equipment may correspondingly obtain the first state information of the switch circuit 130, that is, the register value 0.

The processing unit 1431 is further connected to the storage unit 1435, and is configured to update the state information of the switch circuit 130, so as to store the updated state information in the storage unit 1435.
