It is explicitly and implicitly understood by one skilled in the art that the embodiments described herein can be combined with other embodiments.

The electronic device according to the embodiment of the present application may include various handheld devices, vehicle-mounted devices, wearable devices, computing devices or other processing devices connected to a wireless modem in a 5G NR system, and various forms of User Equipment (User Equipment, UE), a Mobile Station (Mobile Station, MS), a terminal device (terminal device), a Customer Premise Equipment (CPE) or a portable broadband wireless device (Mobile Wifi, MIFI), and the like. For convenience of description, the above-mentioned devices are collectively referred to as electronic devices.

At present, the SRS switching4 antenna transmitting function of a mobile phone is a necessary option of the CMCC of the china mobile communication group in "white paper terminal of the chinese mobile 5G scale test technology", and is selectable in the third generation partnership project 3GPP, and the main purpose of the SRS switching4 antenna transmitting function is to determine the quality and parameters of 4 channels of channels by measuring uplink signals of 4 antennas of the mobile phone by a base station, and perform beam forming of a downlink maximized multi-input multi-output Massive MIMO antenna array for the 4 channels according to channel reciprocity, so as to finally obtain the optimal data transmission performance of the downlink 4x4 MIMO.

In order to meet the requirement of switching transmission of 4-antenna SRS and simultaneous operation of downlink 4X4MIMO in an FDD NR system and/or an FDD LTE system, the radio frequency architecture provided in the embodiment of the present application, which uses a simplified 4PnT antenna switch as a core, can reduce the number of switches connected in series in each path (by integrating all or part of the switches into the 4PnT switch) compared with a 3P 3T/DPDT/multi-path small-switch switching scheme, thereby reducing link loss and optimizing the overall transmission and reception performance of the terminal. The following describes embodiments of the present application in detail.

Referring to fig. 1, fig. 1 is a schematic structural diagram of a multi-way selector switch 10 provided in an embodiment of the present application, the multi-way selector switch is applied to an electronic device 100, the electronic device 100 includes an antenna system 20 and a radio frequency circuit 30, the antenna system 20 includes 4 antennas, the multi-way selector switch 10 includes n T ports and 4P ports, the n T ports include m first T ports and n-m second T ports, the electronic device supports a single-shot mode, each first T port is fully connected to the 4P ports, each second T port is connected to 2P ports of the 4P ports, the P ports connected to a plurality of second T ports supporting signal receiving functions of the same frequency band cover the 4P ports, and the P ports connected to each T port of the 4T ports in a signal receiving state are different from each other, m is equal to 1 or 2 or 4, n is an integer greater than or equal to 4;

the multi-way selector switch 10 is configured to connect the radio frequency circuit 30 and the antenna system 20 to implement a preset function of the electronic device 100 in a frequency division multiplexing FDD system, where the preset function includes a first function and a second function, the first function is to support alternate transmission of SRS between transmitting antennas through sounding reference signals SRS and to transmit SRS with 4 ports, and the second function is to support simultaneous data reception by the 4 antennas.

The function of supporting alternate transmission of the sounding reference signal SRS among the transmitting antennas and transmitting the 4-port SRS refers to a process that the electronic equipment and the base station interactively determine the channel quality corresponding to each antenna through a round training mechanism. The electronic equipment also comprises a radio frequency transceiver which is connected with the radio frequency circuit and forms a radio frequency system of the electronic equipment together with the radio frequency circuit, the multi-way selection switch and the antenna system. When the electronic device is in a downlink 4x4MIMO working mode, the T ports and the P ports in 4 downlink channels of the same frequency band are in one-to-one correspondence. In design principle, four T ports supporting the receiving function in the same frequency band must be connected to 4P ports, respectively, so as to ensure that the downlink four-path receiving function can be realized.

The P Port is called a Port (polarization) Port in the present application, the Port for connecting an antenna in a multiplexer switch in the present application is called a Port, the T Port is called a thru, a Throw in, and the Port for connecting a radio frequency circuit in a multiplexer switch in the present application is called a Port, such as a 4P4T switch.

Because only 1 first T port in the n T ports is fully connected with the 4P ports, and each port in the second T port is only connected with 2 antennas for receiving, compared with the mode that each T port in the 4T ports is fully connected with the 4P ports, the number/volume/cost of field effect tubes built in the 4PnT switch can be reduced, compared with the simplest state that each port in the second T port is only connected with a single P port, the synchronous work of the SRS function and the downlink 4X4MIMO function under the FDD mode is expanded in function, and therefore the applicability is improved. This section is explained in detail below.

For example, if n is 4, the multi-way switch is composed of fets, and if each of the 4T ports is fully connected to 4P ports, the number of fets in the multi-way switch is 4+4 × 3+4 × 56 as shown in the exemplary structure diagram of the multi-way switch shown in fig. 2; if only 1 of the 4T ports is fully connected to 4P ports, and each of the remaining T ports is connected to 2P ports, the number of fets in the multi-way switch is 4+ (1 × 4+ (4-1) × 2) × 3+4 ═ 38, as shown in the exemplary structure diagram of the multi-way switch in fig. 3.

For another example, if n is 5, the multiplexer is composed of fets, and if each of the 5T ports is fully connected to 4P ports, the number of fets in the multiplexer is 5+5 × 4 × 3+4 — 69; if only 1T port of the 5T ports is fully connected to 4P ports, and each of the remaining T ports is connected to 2P ports, the number of fets in the multi-way switch is 5+ (1 × 4+ (5-1) × 2) × 3+4 ═ 45.

Therefore, the number of the T ports which are fully connected with 4P ports in the T ports can be limited, and the switch number of the radio frequency system of the electronic equipment can be effectively reduced. That is, the number of the fully connected T ports has a large influence on the performance of the radio frequency system.

It can be seen that, in the example of the present application, the electronic device includes an antenna system, a radio frequency circuit, and a multi-way selection switch, where the antenna system specifically includes 4 antennas, the multi-way selection switch includes n T ports and 4P ports, and the multi-way selection switch connects the radio frequency circuit and the antenna system, because a second T port of the multi-way selection switch only needs to be connected to 2P ports, a preset function in an FDD system can be implemented, and compared with a switch in which all T ports are fully connected, the switch number can be effectively reduced, thereby reducing insertion loss of a radio frequency link switch, improving an index performance of a radio frequency of the electronic device, and compared with a switch in which the second T port is connected to only a single P port, the preset function in the FDD system can be supported, that is, functionality of the electronic device is expanded.

In one possible example, n is less than or equal to 10; each P port of the 4P ports is connected with a corresponding antenna; each P port of the 4P ports is connected with a corresponding antenna; the first T port supports a signal transceiving function, and the second T port supports only a signal receiving function.

Since the electronic device supports the single-transmission mode, in the new air interface 5G NR system of the fifth generation, the electronic device supports at most dual-frequency single uplink UL2 × 2MIMO downlink DL4 × 4MIMO, that is, logically includes 8 signal receiving paths and 2 signal transmitting paths, and thus corresponds to at most 10T ports, and the value of n is less than or equal to 10.

Wherein, the supporting of the transceiving function refers to supporting of a signal receiving function and a signal transmitting function.

As can be seen, in this example, since the multi-way selector switch is specifically composed of m first T ports and n-m second T ports, the number of switches of the multi-way selector switch is reduced relative to the form in which all the T ports are fully connected to the P port, the number of switches of the radio frequency system of the electronic device can be reduced, and the path loss can be reduced, thereby improving the transmission power and the reception sensitivity, improving the data transmission rate in 5GNR, improving the uplink and downlink coverage of the mobile phone, and reducing the power consumption and the cost.

In one possible example, the single shot mode includes a single frequency single shot mode and a dual frequency single shot mode.

The single-frequency single-transmission mode refers to an operating mode in which the maximum capability of the electronic device can support a single frequency band, a UL single transmission path or a DL4 reception path, and the dual-frequency single-transmission mode refers to an operating mode in which the maximum capability of the electronic device can support a dual frequency band, a UL single transmission path or a DL4 reception path.

In one possible example, the multiway switch includes n first switch tubes, (m × 4+ (n-m) × 2) × 3 second switch tubes, and 4 third switch tubes, the first switch tubes correspond to the T ports, the third switch tubes correspond to the P ports, each 3 second switch tubes are connected in series to form a switch subunit between the T ports and the P ports, 2 second switch tubes at two ends of the switch subunit are respectively connected to 1T port and 1P port, the second switch tube in the middle of the switch subunit is grounded, and gates of each first switch tube, each second switch tube, and each third switch tube are connected to a switch control chip.

In the concrete implementation, when the switch subunit is disconnected, if not grounded, the parasitic parameter has a large influence on the performance of other switched-on ports in the multi-path selection switch, so the switch subunit is set to be 3 switch tubes, wherein 3 switch tubes can be connected in common source, when the switch subunit is disconnected, 2 switch tubes on two sides are all disconnected, and the middle switch tube is grounded.

In the multi-way switch described in the embodiment of the present application, the concepts such as connection and full connection between the T port and the P port all refer to a state where the T port in the multi-way switch is connected to the P port through the switch subunit. The first, second and third switch tubes may be MOS transistors, the electronic device may be connected to the gate of each MOS transistor in the first, second and third switch tubes through a port of a switch control chip, the switch control chip may employ an MIPI interface, and the electronic device may control a signal of a driving port of the switch control chip to control a connection state between any T port and any P port.

Therefore, in this example, the switch subunit of the multi-way selector switch includes three second switch tubes, and the middle second switch tube is grounded, so that the influence of the parasitic parameters of the current switch tube on the performance of other conducting ports can be avoided in the open circuit state, and the switch control stability is improved.

In one possible example, the one shot mode is a single frequency one shot mode, m ═ 1; the radio frequency circuit of the electronic equipment logically comprises a 1-path transmitting signal processing circuit and a 4-path receiving signal processing circuit; the transmitting signal processing circuit and the 1-path receiving signal processing circuit are connected in parallel through a duplexer to form a transmitting signal processing circuit and a receiving signal processing circuit, and the duplexer is used for combining transmitting signals and receiving signals of the same frequency band so as to realize that the electronic equipment can simultaneously work on different frequency points for transmitting and receiving in the FDD mode;

the radio frequency circuit is physically composed of at least 1 independent circuit module;

the signal transceiving ports of the at least 1 independent circuit module are used for connecting the first T port, and the signal receiving ports of the at least 1 independent circuit module are used for connecting the second T port.

The signal receiving and transmitting port is a port of the receiving and transmitting signal processing circuit close to the multi-way selection switch, and the signal receiving port is a port of the receiving signal processing circuit close to the multi-way selection switch.

In this example, the radio frequency processing circuit may be configured to connect the transmit signal processing circuit and the 1-path receive signal processing circuit in parallel through the duplexer to form a receive signal processing circuit, so as to combine transmit signals and receive signals in the same frequency band, implement simultaneous operation of transmitting and receiving at different frequency points in the FDD system, and expand functionality of the electronic device.

In this possible example, as shown in fig. 4A, the transceiver processing circuit includes a power amplifier PA, a low noise amplifier LNA, a duplexer, and a power coupler, the radio frequency transceiver connects the input port of the PA and the output port of the LNA, the output port of the PA and the input port of the LNA connect the duplexer, the duplexer connects the coupler, and the coupler connects the first T port;

the receiving signal processing circuit comprises a Low Noise Amplifier (LNA) and a filter, the radio frequency transceiver is connected with an output port of the LNA, an input port of the LNA is connected with the filter, and the filter is connected with the second T port.

Therefore, in this example, the transmit-receive signal processing circuit and the receive signal processing circuit both support their corresponding functions in a simplified manner, which is beneficial to modularization and cost reduction, and improves the configuration efficiency of the radio frequency system in the electronic device.

In this possible example, n-4, the at least 1 independent circuit module comprises k independent circuit modules, k-1 or 2 or 3 or 4.

As shown in fig. 4B, in the case of a single frequency, n is 4, and m is 1, the number of switching tubes of the multiway switch is 4+ (1 × 4+ (4-1) × 2) × 3+4 is 38, Nx represents a frequency band supported by the electronic device, such as n77(3.3 to 4.2GHz), n78(3.3 to 3.8GHz), n79(4.4 to 4.99GHz), and the like in the 5G NR system, TRX represents a port supporting a signal transceiving function, TX represents a port supporting a signal transmitting function, and RX represents a port supporting a signal receiving function.

When k is 1, the transmit-receive signal processing circuit and the 3 paths of receive signal processing circuits are arranged in the same independent circuit module;

when k is 2, the transceiving signal processing circuit and the 3 channels of receiving signal processing circuits are disposed in 2 independent circuit modules, for example, a first independent circuit module is disposed with the transceiving signal processing circuit, and a second independent circuit module is disposed with the 3 channels of receiving signal processing circuits, etc., which is not limited herein;

when k is 3, the transceiving signal processing circuit and the 3 receiving signal processing circuits are arranged in 3 independent circuit modules, for example, a first independent circuit module is provided with the transceiving signal processing circuit, a second independent circuit module is provided with 2 receiving signal processing circuits, and a third independent circuit module is provided with 1 receiving signal processing circuit, which is not limited uniquely here;

when k is 4, the transmitting/receiving signal processing circuit and the 3-path receiving signal processing circuit are arranged in 4 independent circuit modules.

It can be seen that, in this example, the physical form of the rf circuit adapted to the 4P4T multi-way selector switch may be various, and may be flexibly configured according to the requirement.

In one possible example, the single shot mode is a dual frequency single shot mode, where m is 1; the radio frequency circuit of the electronic equipment logically comprises 2 paths of transmitting signal processing circuits and 8 paths of receiving signal processing circuits; each path of transmitting signal processing circuit and 1 path of receiving signal processing circuit supporting the same frequency band are connected in parallel through a duplexer to form a transmitting and receiving signal processing circuit, 2 paths of transmitting and receiving signal processing circuits of different frequency bands are connected in parallel through a change-over switch to form a transmitting and receiving signal integrated circuit, and the duplexer is used for combining transmitting signals and receiving signals of the same frequency band so as to realize that the electronic equipment can simultaneously work on different frequency points in the FDD mode in transmitting and receiving;

The signal receiving and transmitting port is a port of the signal receiving and transmitting integrated circuit close to the multi-way selection switch, and the signal receiving port is a port of the received signal processing circuit close to the multi-way selection switch.

It can be seen that, in this example, the radio frequency processing circuit may be configured with the transmit signal processing circuit and the 1-channel receive signal processing circuit in parallel via the duplexer, so as to combine transmit signals and receive signals in the same frequency band, thereby implementing simultaneous operation of transmitting and receiving signals in different frequency points in the FDD system, and the 2-channel transmit/receive signal processing circuits corresponding to two frequency bands may implement frequency band selection via the switch, thereby facilitating expansion of functionality of the electronic device.

In the present possible example, as shown in fig. 5A, the transceiver integrated circuit includes a first power amplifier PA, a first low noise amplifier LNA, a first duplexer, a second power amplifier PA, a second low noise amplifier LNA, a second duplexer, a power coupler, and a switch (e.g., a single pole double throw SPDT switch), the radio frequency transceiver is connected with the input port of the first PA, the input port of the second PA, the output port of the first LNA, the output port of the second LNA, an output port of the first PA and an input port of the first LNA are connected to the first duplexer, an output port of the second PA and an input port of the second LNA are connected to the second duplexer, the first duplexer and the second duplexer are connected with the coupler, the coupler is connected with the change-over switch, and the change-over switch is connected with the first T port;

In FDD mode and single-shot mode, the PAs in the multiple transmit signal processing circuits do not work simultaneously, so that multiple PAs in the multiple transmit signal processing circuits can be arranged in the same independent circuit module.

In this example, the transceiving signal integrated circuit and the receiving signal processing circuit both support their corresponding functions in a simplified manner, which is beneficial to modularization and cost reduction, and improves the configuration efficiency of the radio frequency system in the electronic device.

As shown in fig. 5B, in the case of dual-frequency single-shot, where n is 4, and m is 1, the number of switching tubes of the multiway switch is 4+ (1 × 4+ (4-1) × 2) × 3+4 is 38, Nx represents a first frequency band supported by the electronic device, Ny represents a second frequency band supported by the electronic device, such as n77(3.3 to 4.2GHz), n78(3.3 to 3.8GHz), n79(4.4 to 4.99GHz), and TRX represents a port supporting a signal transceiving function, TX represents a port supporting a signal transmitting function, and RX represents a port supporting a signal receiving function.

Wherein, the 6-path receiving signal processing circuits except the 2-path receiving signal processing circuits of the receiving and transmitting signal integrated circuit are divided into 3 groups of receiving circuits, each group of receiving circuits respectively comprises 2-path receiving signal processing circuits with different frequency bands, and are connected in parallel through a switch, and the exemplary circuit structure is shown in fig. 5A in detail.

When k is 1, the transceiver integrated circuit and the 3 groups of receiving circuits are arranged in the same independent circuit module;

when k is 2, the transceiver integrated circuit is disposed in 1 independent circuit module, at least 1 group of receiver circuits in 3 groups of receiver circuits is disposed in another 1 independent circuit module, for example, the first independent circuit module is disposed with the transceiver integrated circuit, and the second independent circuit module is disposed with 3 groups of receiver circuits, which is not limited herein;

when k is 3, the transceiver integrated circuit is disposed in 1 independent circuit module, at least 2 groups of transceiver circuits in 3 groups of transceiver circuits are disposed in another 2 independent circuit modules, for example, the first independent circuit module is disposed with the transceiver integrated circuit, the second independent circuit module is disposed with 2 groups of transceiver circuits, the third independent circuit module is disposed with 1 group of transceiver circuits, and the only limitation is not made here;

when k is 4, the transceiver integrated circuit and the 3 sets of receiving circuits are respectively arranged in 4 independent circuit modules.
