Description

Communication method and electronic equipment
Technical Field
The application relates to the technical field of radio frequency, in particular to a communication method and electronic equipment.
Background
With the development of communication technology, the fifth Generation mobile communication technology (5 th-Generation, 5G) is increasingly used. The networking mode of the 5G base station comprises the following steps: independent networking (SA) mode and non-independent Networking (NSA) mode. The NSA mode refers to a mode of performing 5G base station deployment networking on an existing 4G base station, and needs to satisfy that a 4G signal (for example, a B3 band signal, a B39 band signal, etc.) and a 5G signal (for example, an N40 band signal, an N41 band signal, etc.) can work together, for example, a double-link (E-UTRAN New Radio-Dual Connectivity, ENDC) combination of an N41 band+b3 band (abbreviated as n41+b3) can be adopted in the NSA mode.
Among Duplex modes of a communication system, the most commonly used two modes are a Time-division Duplex (TDD) mode and a Frequency-division Duplex (FDD) mode, wherein the TDD mode refers to an operation mode in which a reception channel (RX) and a transmission channel (TX) are in different Time slots of the same Frequency channel, and the FDD mode refers to an operation mode in which the RX and the TX are in different Frequency channels. In the communication field, a frequency band to which the TDD mode is applied may be referred to as a TDD frequency band, and a frequency band to which the FDD mode is applied may be referred to as an FDD frequency band. Illustratively, the TDD frequency band includes N40, N41, etc., and the FDD frequency band includes B1, B3, etc.
The base station can perform directional transmission to the terminal, at this time, the terminal can feed back information to the base station through a channel sounding reference signal (Sounding Reference Signal, SRS) function, and the information can be used for estimating uplink timing, and estimating downlink channel quality by using channel symmetry, and the base station allocates Resource Blocks (RBs) with good instantaneous channel state to uplink PUSCH transmission of the terminal, and simultaneously selects different transmission parameters.
In the ENDC scenario, long term evolution (Long Term Evolution, LTE) and New Radio (NR) operate simultaneously, requiring two transmit modules, while LTE and NR require four-way reception. The two transmitting modules can bear two paths of receiving, two paths of receiving are needed, and the other two paths of receiving are completed by the two receiving modules. Therefore, in order to realize ENDC, two transmitting modules and two receiving modules are required. To simplify the analytical description, they can be divided into two groups, each group comprising: the transmitting module is connected with the first antenna, the transmitting module is connected with the second antenna, and when the transmitting module is applied to the N41 frequency band and the B3 frequency band, the transmitting module needs to perform N41 SRS round trip transmission. In the related application, the B3 receiving channel in the receiving module cannot work simultaneously with the SRS channel, and when the transmitting module transmits the signal of the N41 frequency band to the receiving module, the receiving module will interrupt the receiving of the signal of the B3 frequency band. The downlink throughput of the receiving module to the B3 band signal is affected, so that the user experience is affected.
Therefore, how to realize the transmission of the high-frequency signal (such as N41) SRS by the transmitting module in the ENDC scene without interrupting the reception of the intermediate-frequency signal (such as B3) by the receiving module is a technical problem to be solved in the application.

Fig. 1 is a schematic diagram of an application scenario where the communication method provided in the embodiment of the present application is applicable. As shown in fig. 1, the electronic device may communicate with the base station through a communication network, and the specific type of the communication network is not limited herein, and may be, for example, a cellular mobile communication network.
The communication method, the related module and the electronic device provided by the embodiment of the application can be applied to mobile phones, tablet computers, personal digital assistants (personal digital assistant, PDAs), wearable devices, vehicle-mounted communication terminals, augmented reality (augmented reality, AR)/Virtual Reality (VR) devices, notebook computers, ultra-mobile personal computer (UMPC) personal computers, netbooks, and other electronic devices, and the specific types of the electronic devices are not limited in the embodiment of the application.
Fig. 2 is a schematic diagram of a part of a circuit of an electronic device with signal flow direction in the related art, and the electronic device 200 includes: a receiving module 210, a transmitting module 220, a transceiver 230 and a baseband chip 240. The electronic device 200 may apply to a transmission scenario in which the first signal and the second signal are transmitted in an ENDC scenario, such as a transmission scenario in which the first signal (N41) is polled and the second signal (B3) is received from a diversity antenna. The first signal is a high-frequency signal of a time division duplex frequency band, and the second signal is an intermediate-frequency signal of the frequency division duplex frequency band. In the description of the embodiment of the present application, the first signal is exemplified by a signal in the N41 frequency band (hereinafter, abbreviated as N41), and the second signal is exemplified by a signal in the B3 frequency band (hereinafter, abbreviated as B3). The receiving module 210 includes: a first controller, a first switch, a first antenna port ANT1, a second antenna port ANT2, a radio frequency port TRX1, a first filter bank and a low noise amplifier bank. The first filter bank includes: a receive filter for the first signal and a receive filter for the second signal. The first antenna port ANT1 of the receiving module is connected with the first antenna, and the first antenna port ANT3 of the transmitting module is connected with the second antenna. The radio frequency port TRX2 of the transmitting module is connected with the second antenna port ANT2 of the receiving module; the radio frequency port TRX1 of the receiving module is connected to the second antenna port ANT4 of the transmitting module. When the electronic device performs SRS round for N41, the transmitting module 220 sends a signal N41 through the first antenna connected to the receiving module 210, where the signal flows as shown in cc' in fig. 2, and the communication link between the receiving filters of the N41 through TRX1 and ANT1, ANT1 and B3 is disconnected (the communication link is disconnected as indicated by the cross identifier in fig. 2, for example, by controlling the switch branch between the receiving filters connected to ANT1 and B3 in the first switch to be disconnected). Accordingly, the B3 receive path dd' of the receive module 210 is disconnected, the impedance of the receive module changes, and this communication method affects the error vector magnitudes (error vector magnitude, EVM) of B3TX and B3RX, resulting in degradation of the throughput of B3.
It should be noted that, in the related art, when the transmitting module transmits the signal of the N41 frequency band to the receiving module, the receiving module receives the signal of the B3 frequency band, which has two reasons:
for one reason, the transmitting module and the receiving module are two different modules, and an N41 filter inside the transmitting module and a B3RX filter inside the receiving module work at the same time in a double-on mode, so that impedance mismatch influences the matching of B3 RX.
For the second reason, the register of the receiving module may not support the dual-open of the TRX1 and the built-in filter, because the platform requires that the control of LTE and NR is decoupled in the ENDC scenario, that is, only the SRS round of N41 is controlled, and the configuration of B3RX cannot be affected.
Based on the two reasons, the downlink throughput of the receiving module to the B3 band signal is affected, so that the user experience is affected.
Therefore, how to realize the transmission of the high-frequency signal (such as N41) SRS by the transmitting module in the ENDC scene without interrupting the reception of the intermediate-frequency signal (such as B3) by the receiving module is a technical problem to be solved in the application, and the method can comprise the design of impedance matching and the design of a register of two modules.
The following describes the technical solution of the present application by taking an ENDC scenario of n41+b3 as an example, please refer to fig. 3A to 3H, wherein fig. 3A is a schematic flow chart of a communication method provided in an embodiment of the present application, and the method is used in an electronic device for transmitting a first signal and a second signal. As shown in fig. 3B, the electronic device 300 includes a receiving module 310 and a transmitting module 320. The first signal is a high-frequency signal of a time division duplex frequency band, and the second signal is an intermediate-frequency signal of a frequency division duplex frequency band. The receiving module 310 includes: a first controller, a first switch, a first antenna port ANT1, a second antenna port ANT2, a radio frequency port TRX1, a first filter bank, a second switch, and a first low noise amplifier bank LNA1; the first controller includes: a first register, a second register, and a third register; the first filter bank includes: a receiving filter for the first signal and a receiving filter for the second signal; the first antenna port ANT1 of the receiving module 310 is connected with the first antenna, the first antenna port ANT3 of the transmitting module 310 is connected with the second antenna, and the radio frequency port TRX2 of the transmitting module is connected with the second antenna port ANT2 of the receiving module; the radio frequency port TRX1 of the receiving module is connected to the second antenna port ANT4 of the transmitting module, and the first signal is a high frequency signal, and the second signal is an intermediate frequency signal. For convenience of description, the embodiment of the present application uses the first signal as N41 and the second signal as B3 as an example, and it can be understood that the first signal may also be other high-frequency signals, and the second signal may also be other intermediate-frequency signals, which is not limited herein. As shown in fig. 3A, the communication method includes the steps of: 301 to 304.
301. The first controller acquires a first control command sent by the transceiver, and determines the transmission mode of the current communication according to the first control command.
Wherein the transmission mode includes: a first transmission mode, a second transmission mode, and a third transmission mode; the first transmission mode corresponds to a scene that the transmitting module transmits a first signal through a second antenna connected with the transmitting module; the second transmission mode corresponds to a scene that the transmitting module transmits a first signal through a first antenna of the receiving module; the third transmission mode corresponds to a scene of the receiving module receiving the first signal.
302. When the transmission mode of the current communication is the first transmission mode, the first controller controls the communication link between the ANT1 and the reception filter of the first signal to be on, and controls the communication link between the ANT1 and the reception filter of the second signal to be on, and controls the communication link between the ANT2 and the TRX1 to be on, and controls the communication link between the reception filter of the first signal and the LNA1 to be off.
In some possible embodiments, the first controller comprises; a first register, a second register, and a third register; the first controller acquires a first configuration message sent by the transceiver, and configures the value of the first register to be: the identity of the first signal and the identity of the second signal (e.g., n41+b3), and configuring the value of the second register according to the first configuration message to be: the identification of the second signal and the identification of the first signal by the TRX1 round (e.g., b3+trx1); setting the value of the third register to a first preset value (for example, a numerical value of 0) when the transmission mode of the current communication is the first transmission mode; setting the value of the third register to a first preset value (for example, a numerical value of 0) when the transmission mode of the current communication is a third transmission mode; when the transmission mode of the current communication is the second transmission mode, the value of the third register is set to a second preset value (for example, a value of 1).
In some possible embodiments, the configuration message sent by the transceiver may be set by using a bit mask, where any one bit is high (e.g., a value of 1), which indicates that the communication link corresponding to the bit is connected, and when two or more bits are set high, the configuration is implemented with two or more bits. The related configuration of the registers is shown in fig. 3F and fig. 3G, where the first register regA and the second register regB control the logic of the ANT1 and the ANT2 respectively, for example, the register a includes 8 storage bits, and if the lowest bit is 1, the filter communication link corresponding to the ANT1 and the first port P1 is turned on (for example, the switch branch between the two can be controlled to be closed); if the value of the third last bit of the register is 1, the communication link between the ANT1 and the filter corresponding to the third port P3 is conducted, and if the last bit and the second last bit are both 1, the communication link between the ANT1 and the filters corresponding to P1 and P2 are conducted. If the communication links corresponding to the P1 and N41 filters are required to be set to be conductive, the communication links corresponding to the P4 and B3 filters are required to be conductive, and the values of the lowest bit and the fourth last bit of the first register can be set to be 1, then the two-on of N41 and B3 can be realized.
In some possible embodiments, when the transmission mode of the current communication is the first transmission mode, the first controller controls the communication link between ANT1 and the receiving filter of the first signal to be on, controls the communication link between ANT1 and the receiving filter of the second signal to be on, controls the communication link between ANT2 and the TRX1 to be on, and controls the communication link between the receiving filter of the first signal and the LNA1 to be off according to a preset configuration rule and the values of the transceiver to be configured for the first register, the values to be configured for the second register, and the values to be configured for the third register. The preset configuration rules comprise: configuring ANT1 with a value configured for a first register, configuring ANT2 with a value configured for a second register, the priority of ANT1 being higher than the priority of ANT2, the first controller only responding to the configuration of any configured value in ANT1 when the any configured value is configured in both ANT1 and ANT 2; when the value of the third register is a first preset value, the communication link between the receiving filter of the first signal and the LNA1 is disconnected; and when the value of the third register is a second preset value, indicating a communication link between the receiving filter for communicating the first signal and the LNA 1. For example, P4 is set to be valid in regA, and P4 is set to be valid in regB, so that P4 is communicated to ANT1 according to the priority order, and P4 is prevented from being communicated to ANT1 and ANT2 at the same time.
regD is a control register for antenna switching, and when regD [0] =0, ANT1 is configured with regA, ANT2 is configured with regB; when regD [0] =1, ANT1 is configured with regB, ANT2 is configured with regA, ANT1 has a higher priority than ANT2, and when any configured value is configured in both ANT1 and ANT2, the first controller responds only to the configuration of any configured value in ANT 1.
Fig. 3G is a diagram illustrating the configuration of the receiver module register. On a System On Chip (SOC) platform, the transmission and reception of N41 is divided into two paths, i.e., path 1 and path 2. The platform has a constraint that when N41 makes SRS round-robin, no matter which antenna is round-robin, the configuration of path 1 must be maintained unchanged, and only the configuration of path 2 can be changed. The following describes how the present invention satisfies this constraint.
As shown in fig. 3G, in the default state (i.e., the first transmission mode), regA (i.e., the first register) is set to: n41+b3 (corresponding to p1+p4 in fig. 3F being simultaneously turned on to ANT 1), regB (i.e. the second register) is set as: trx1+b3 (corresponding to p6+p3 being simultaneously turned on to ANT2 in fig. 3F), regD (i.e., the third register) is set to 0, and in this transmission mode, the signal flows to the communication link aa ' of the round N41 and the communication link bb ' of the reception B3 are turned on as shown in fig. 3B, and the first controller controls the communication link between the reception filter of N41 and the LNA1 to be disconnected, and the communication link cc ' to be disconnected.
The first controller controls the disconnection of the communication link between the receive filter of N41 and LNA1, which can be achieved by: the switching branch connecting the receiving filter of the first signal and the LNA1 is controlled to be opened. Further, in a possible implementation, the LNA branch corresponding to the first signal in LNA1 may also be turned off (i.e. the state of the LNA is switched off). This is advantageous in that when the communication link is disconnected, the control related elements are not operated, no power is consumed any more, and power consumption is reduced. 303. When the transmission mode of the current communication is the second transmission mode, the first controller controls the communication link between ANT1 and TRX1 to be on, controls the communication link between ANT1 and the receiving filter of the second signal to be on, controls the communication link between ANT2 and the receiving filter of the first signal to be on, and controls the communication link between the receiving filter of the first signal and LNA1 to be off.
In some possible embodiments, when the transmission mode of the current communication is the second transmission mode, the first controller controls the communication link between ANT1 and TRX1 to be on, controls the communication link between ANT1 and the receiving filter of the second signal to be on, and controls the communication link between ANT2 and the receiving filter of the first signal to be on, and controls the communication link between the receiving filter of the first signal and LNA1 to be off, according to a preset configuration rule, and the values of the transceiver to be on the first register, the values to be on the second register, and the values to be on the third register.
The preset configuration rule further comprises: when the transmission mode of the current communication is the second transmission mode, the ANT1 is configured by using the value configured for the second register, the ANT2 is configured by using the value configured for the first register, the priority of the ANT1 is higher than the priority of the ANT2, and when any configured value is configured in both the ANT1 and the ANT2, the first controller only responds to the configuration of any configured value in the ANT 1. For example, P4 is disposed in ANT1 and P4 is also disposed in ANT2, and the communication to ANT1 is performed according to the priority order P4, thereby avoiding the simultaneous communication of P4 to ANT1 and ANT2.
As shown in fig. 3G, in the cross state (i.e., the second transmission mode), regA (i.e., the first register) is set as follows: n41+b3 (corresponding to p1+p4 in fig. 3F being simultaneously turned on to ANT 1), regB (i.e. the second register) is set as: trx1+b3 (corresponding to p6+p3 being simultaneously turned on to ANT2 in fig. 3F), and regD (i.e., the third register) is set to 1, it can be understood from fig. 3F that, when regd=1, ANT2 is controlled by regA and ANT1 is controlled by regB, and it can be understood that ANT1 is configured with the value configured for the second register, and ANT2 is configured with the value configured for the first register, that is: trx1+b3 to ANT1, n41+b3 to ANT2, and likewise, ANT1 has a higher priority than ANT2, and B3 is connected to ANT1, thereby avoiding simultaneous connection of B3 to ANT1 and ANT2. As shown in fig. 3C, the communication link dd ' of the burst N41 and the communication link bb ' of the reception B3 are turned on, and the first controller controls the reception filter of the N41 to be disconnected from the LNA1, and the communication link cc ' to be disconnected.
304. When the current transmission mode is the third transmission mode, the first controller configures the ANT1 to be connected with the LNA1 according to the values of the first register and the second register, and the ANT1 to be connected with the receiving filter of the first signal and the receiving filter of the second signal.
From the above description we can see that the configuration of path 1 is always the same, no change occurs, we have only changed the configuration of path 2. Only the third register involved in path 2 realizes N41 SRS round-robin different antennas using the priority order of ANT1 and ANT 2.
In some possible embodiments, when the transmission mode of the current communication is the third transmission mode, the first controller controls communication link conduction between ANT1 and the receiving filter of the first signal, and communication link conduction between ANT1 and the receiving filter of the second signal, and communication link conduction between ANT2 and the TRX1, and communication link conduction between the receiving filter of the first signal and the LNA1 according to a preset configuration rule, and values of the transceiver to the first register, the second register, and the third register. The preset configuration rule further comprises: when the transmission mode of the current communication is the third transmission mode, the ANT1 is configured by using the value configured for the first register, the ANT2 is configured by using the value configured for the second register, the priority of the ANT1 is higher than the priority of the ANT2, and when any configured value is configured in both the ANT1 and the ANT2, the first controller only responds to the configuration of any configured value in the ANT 1.
As shown in fig. 3G, when receiving N41 (i.e., the third transmission mode), the regA (i.e., the first register) is set to: n41+b3, the regB (i.e. second register) is set to: trx1+b3, where regD (i.e., the third register) is set to 0, as can be seen from fig. 3F, when regd=0, ANT1 is configured by regA, ANT2 is configured by regB, and similarly, ANT1 has a higher priority than ANT2, B3 is set in ANT1, and B3 is set in ANT2, and only the configuration of ANT1, i.e., B3 is connected to ANT1, is responded to according to the priority order, thereby avoiding simultaneous connection of B3 to ANT1 and ANT2. The signal flow is as shown in fig. 3D, with communication links ee ', bb ', cc ' conducting.
Based on the scheme, the register is configured, and the receiving filter of the first signal in the receiving module is connected or disconnected with the LNA, so that when the receiving module is in the first transmission mode, the second transmission mode and the third transmission mode, the receiving filter of the first signal and the receiving filter of the second signal are kept on two sides, and the receiving module can not interrupt the receiving of the second signal when the transmitting module transmits the first signal through the receiving module, so that the throughput of the second signal is not affected.
In some possible embodiments, as shown in fig. 3E, an impedance reduction module is provided between the TRX1 and the ANT4, and as shown in fig. 3H, the communication method includes steps 301 to 305. Steps 301 to 304 are the same as those in the embodiment shown in fig. 3A, and refer to the description in the embodiment corresponding to fig. 3A, which is not repeated here.
305. The first controller controls connection or disconnection of the configurable branch in the impedance restoration module such that, in an ENDC scenario, the impedance is 50 ohms at the first signal and is high at a value greater than a preset value at the second signal when viewed from the TRX1 to the transmission module, and such that the impedance seen from the TRX1 to the transmission module coincides with the impedance seen from the ANT4 of the transmission module to the transmission module.
The impedance restoration module is arranged to realize the double opening of the two modules, and the impedance seen by the TRX1 port of the receiving module to the transmitting module is consistent with the impedance seen by the ANT4 port of the transmitting module to the transmitting module. The transmitting module and the receiving module are at a certain distance on the printed circuit board (Printed circuit board, PCB), and a certain length of wiring, such as 50-80 mm, is connected in the middle, as shown in FIG. 4A, the variation of impedance in different frequency bands can be caused by the wiring from the ANT4 of the transmitting module to the TRX1 of the receiving module. The phase shift generated by the PCB trace length corresponding to different frequency bands is shown in FIG. 4A (it should be noted that, the phase shift shown in FIG. 4A is the degree of rotation on the smith chart, and the corresponding electrical length is half the degree of rotation on the smith chart). As can be seen from fig. 4A, for a trace of a certain length, the phase shift caused by the trace is different for different frequency points, and is proportional to the frequency, for example, the phase shift caused by the trace of 10mm is 43 degrees for a signal of 1.8Ghz, 53 degrees for a signal of 2.2Ghz, and 43 degrees for a signal of 2.5 Ghz. While for the same frequency point, different lengths are proportional to the phase shift, for example, for a 1.8GHz signal, the phase shift by a 10mm trace is 43 degrees and the phase shift by a 20mm trace is 86 degrees.
Taking the second transmission mode in the ENDC scenario as an example, see fig. 3C and 5, the impedance of N41 is always near the center a, approaching 50 ohms for an in-band signal. However, for B3, the impedance shifts more, and at ANT4 of the transmitting module, the impedance of B3, although at the open position, after passing through the microstrip line of 50mm, becomes the position indicated by reference symbol B in fig. 6, which has been far from the open region. Thus, in the receive module, if the TRX1 port is directly double-ended with the internal B3 receive filter, an impedance mismatch may result. Accordingly, as shown in fig. 3E, an impedance restoration module may be provided between the TRX1 port of the reception module and the ANT4 port of the transmission module, to restore the impedance of the TRX1 port of the reception module to the impedance at the ENDC module ANT 4.
The impedance reduction module may include a capacitor and/or a filtering electric quantity of an inductor, where the capacitor may be connected in series or in parallel, and the inductor may be connected in series or in parallel, and a specific circuit form may be adjusted according to an adapted frequency band, which is not limited herein. The impedance restoration module also comprises a switch module, and whether each configurable capacitor or inductor is connected to the filter circuit is selected by setting the on-off of different branches of the switch module, so that the overall impedance state of the impedance restoration module is adjusted, and the impedance tuning is realized.
In some possible embodiments, the impedance reduction module may include: a first branch, a second branch, a third branch and a switch module connected between the TRX1 and the ANT 4; the first branch comprises a first inductor and a PCB wire, wherein the first end of the first inductor is connected with the TRX1, the second end of the first inductor is connected with the first end of the PCB wire, and the second end of the PCB wire is connected with the ANT 4; the second branch comprises a first capacitor which is connected between the first end of the first inductor and the ground in a configurable way through a switch, and the third branch comprises a second capacitor which is connected between the second end of the first inductor and the ground. As shown in fig. 7, in one embodiment, the impedance restoration module 700 is located between the TRX1 port of the receiving module and the ANT4 port of the transmitting module, the first branch includes a first inductor 701 and a PCB trace 702, the second branch includes a first capacitor 903, and the third branch includes a second capacitor 704. When desired, the PCB trace 702 may shift the impedance to an opposite high-impedance region (e.g., near 270 degrees), away from the low-impedance region, facilitating out-of-band and in-band impedance matching. The first capacitor 703, the second capacitor 704 and the first inductor 701 form a configurable impedance matching module, and the first capacitor 703 is configured by a switch (the switch is not shown in the figure), and can be connected to or disconnected from an impedance reduction module.
Assuming that the length of the connection line between the ANT4 port of the transmitting module and the TRX1 port of the receiving module is 50mm, the impedance position of the B3 band is shown in fig. 6 after the connection line is routed by 50mm, and assuming that the band related to N41 ENDC also has B1 at the same time, when designing the impedance reduction module, the band of B1 needs to be comprehensively considered, and the impedance position of the B1 band is shown in fig. 8 after the connection line is routed by 50 mm. To achieve impedance reduction, an additional phase shifting network is required to shift the impedance of B3 to a relatively high impedance region. As shown in fig. 7, adding 10mm extra traces, a total of 60mm length PCB traces, the impedance of both B3 and B1 can be tuned to the high impedance region. As shown in D in fig. 9 and E in fig. 10, by providing PCB traces, a foundation is laid for further configuring the network impedance restoration module.
As shown in fig. 11, the electrical length of the trace is 60mm, which can be seen as adding an additional phase-shifting trace of 10mm length to the original 50mm trace. The 0.8pF capacitor in fig. 11 may be configured to be on (i.e., 0.8pF capacitor is connected to the impedance reduction module as shown in fig. 11) or the 0.8pF capacitor may be configured to be off (i.e., 0.8pF capacitor is disconnected from the impedance reduction module as shown in fig. 12), for example, may be configured to be on at the time of B3; at B1, is configured to be off.
In the SA mode, each frequency band is switched from ANT4 of the ENDC module to TRX1 of the receiving module, so that the impedance restoration network should implement impedance restoration of each frequency band in the SA mode. Such as B1/3/39/40/41/7, etc., are essentially all MB and HB bands. This presents a further challenge for impedance restoration networks that consider SA modes for all MB and HB bands in addition to satisfying the N40 and N41 related EDNC scenario impedance restoration.
With the multi-switch design of the receiving module switch, a degree of freedom of design can be added to the TRX3, that is, an inductor, such as the inductor 1305 in fig. 13, is connected in parallel, so that the inductor 1305 is connected in parallel with the fixed inductor 1303, and therefore, the adjustment of the inductor is realized. In fig. 13, a configurable capacitor 1304 is connected in parallel with the TRX3 branch and may be configured to connect to or disconnect from the TRX3 port.
The following describes the design process of the impedance reduction module with reference to fig. 4B. When designing the impedance restoration network module, the design of the PCB trace length and the design of the element values in the impedance restoration module (which may be achieved by configuring related elements to be connected or disconnected with the impedance restoration network module) are mainly included, and the related flow is shown in fig. 4B, and may include steps 401 to 409.
401. The distance of the connection line between the ANT4 port of the transmitting module and the TRX1 of the receiving module is determined.
402. Judging whether the phase shift caused by the connection line exceeds a first preset value. I.e. if the impedance of the electrical length corresponds to a high resistance region on the smith circle.
If the determination result is yes, step 403 is executed, and if the determination result is no, step 404 is executed. For example, the first preset value may be 135 °, if the phase shift is 151 °, step 403 is performed, and if the phase shift is not greater than 103 °, step 404 is performed.
403. No additional compensation wires are added.
404. Adding additional compensation wiring may be accomplished, for example, by increasing the length of the wiring on the PCB.
405. And determining the phase shift position of the relevant frequency Band Counter Band according to the total length of the connecting line.
406. Optimizing the component values of the impedance-reducing network can be achieved, for example, by configuring the switch to connect or disconnect a branch.
407. It is determined whether the impedance corresponding to Counter Band is to the high impedance region on the smith circle and whether the in-Band is 50 ohms.
If the determination result is yes, step 408 is executed, and if the determination result is no, step 406 is executed.
408. Whether the SA Band is in the vicinity of 50 ohms or not is judged, for example, whether the impedance of the relevant frequency Band is different from the impedance of 50 ohms or not is judged to be in a preset range.
If yes, go to step 410; if the determination result is no, step 409 is performed.
409. A radio frequency port TRX double-opening adjusting network is added, and a design degree of freedom is increased.
410. And determining an impedance reduction network, and finishing the setting of the impedance reduction network.
By adopting the scheme, whether the impedance corresponding to the electric length is larger than 135 degrees (relative high-resistance area) in the Smith is determined according to the layout of the PCB, and the impedance corresponding to the electric length reaches more than 135 degrees in the Smith chart by adding an additional compensation wiring, namely, the lowest frequency band meets 135 degrees. Then optimizing the value of the impedance restoration network, and controlling a configurable capacitor to realize impedance matching of NSA scenes, namely counter band to a high-resistance area, wherein an in-band frequency band is near 50 ohms; finally, whether the impedance of all frequency bands of the SA scene is near 50 ohms is checked, and a multi-branch can be added, so that a design degree of freedom is increased. As in fig. 13, the configurable inductance 1305 of TRX 4.
Based on the register configuration of the method, the device and the system, N41 SRS round trip transmission does not interrupt the receiving of the receiving module to B3 in an ENDC scene can be realized. The non-breaking is based on the two modules being capable of being opened in two.
