Description

Technical Field

[0001] The embodiments of the present application relate to the field of communications, and in particular to a signal transmission method and a wireless communication device. Background Art

[0002] At present, many 5G terminal devices can perform 4G (4th Generation Mobile Communication Technology) and 5G (5th Generation Mobile Communication Technology) communications when they are in EN-DC (a scenario of LTE (Long Term Evolution)-NR (New Radio) dual connection). Among them, 4 antennas are set in the terminal device, 2 antennas are used for sending and receiving 4G signals, and 2 antennas are used for sending and receiving 5G signals. 5G supports SRS (Sounding Reference Signal) transmission: 1T2R SRS ("T" transmit, send; "R" receive), that is, the SRS signal is sent in turn on 2 receiving antennas; and 1T4R SRS, that is, the SRS signal is sent in turn on 4 receiving antennas. Among them, when using 1T4R SRS, the base station can obtain the uplink channel information sent by all four antennas; compared with the use of 1T2R SRS, the uplink channel information obtained by the base station is more comprehensive, and the base station channel estimation is more accurate, so that more accurate downlink resource allocation can be performed, thereby improving the downlink peak rate.

[0003] If the terminal device uses 1T4R SRS, although it can improve the downlink peak rate, it will occupy the antennas used for 4G signal transmission and reception, making the two antennas unable to send 4G signals, interrupting LTE services, causing LTE service rates to drop or even disconnect. If 1T2R SRS is used, although it will not occupy the antennas used for 4G signal transmission and reception, it will reduce the downlink peak rate. Summary of the invention

[0004] In order to solve the above technical problems, the present application provides a signal transmission method and a wireless communication device; the method can realize 4-way round-robin transmission of the SRS of the first network without interrupting the service of the second network.

[0037] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0038] The term "and / or" in this article is merely a description of the association relationship of associated objects, indicating that three relationships may exist. For example, A and / or B can mean: A exists alone, A and B exist at the same time, and B exists alone.

[0039] The terms "first" and "second" in the description and claims of the embodiments of the present application are used to distinguish different objects rather than to describe a specific order of objects. For example, a first target object and a second target object are used to distinguish different target objects rather than to describe a specific order of target objects.

[0040] In the embodiments of the present application, words such as "exemplary" or "for example" are used to indicate examples, illustrations or descriptions. Any embodiment or design described as "exemplary" or "for example" in the embodiments of the present application should not be interpreted as being more preferred or more advantageous than other embodiments or designs. Specifically, the use of words such as "exemplary" or "for example" is intended to present related concepts in a specific way.

[0041] In the description of the embodiments of the present application, unless otherwise specified, the meaning of "multiple" refers to two or more than two. For example, multiple processing units refer to two or more processing units; multiple systems refer to two or more systems.

[0042] The embodiments of the present application can be applied to LTE-NR scenarios. For example, the embodiments of the present application can be applied to EN-DC scenarios (a scenario in LTE-NR scenarios).

[0043] Figure 1An exemplary application scenario diagram of an embodiment of the present application. The wireless communication system 100 in the EN-DC scenario may include: a 4G core network 110, a 4G base station 120, a 5G base station 130, and a terminal device 140. Among them, the 4G base station 120 is connected to the 4G core network 110 as a primary base station, the 5G base station 130 is connected to the 4G base station 120 as a secondary base station, and the terminal device 140 can be connected to the 4G base station 120 and the 5G base station 130 respectively.

[0044] When the terminal device is in the EN-DC scenario, the terminal device can perform 4G communication and 5G communication at the same time. During the 5G communication, the terminal device 140 can transmit a 5G SRS to the 5G base station 130. After receiving the 5G SRS transmitted by the terminal device 140, the 5G base station 130 can perform uplink channel estimation according to the 5G SRS, and then perform downlink resource allocation according to the uplink channel estimation result.

[0045] Among them, the terminal device supports two round-trip strategies, 1T2R and 1T4R. The 1T4R round-trip strategy has a higher downlink peak rate than the 1T2R round-trip strategy. Usually, 2 antennas of the 4-antenna terminal device of the prior art are used for 4G communication, and 2 antennas are used for 5G communication. If the 1T4R round-trip strategy is adopted, the 4G service will be interrupted. Therefore, in order to avoid the impact on the 4G service of the terminal device when the 1T4R round-trip strategy is adopted, the 4-antenna terminal device usually adopts the 1T2R round-trip strategy, so that the downlink peak rate of the terminal device will be affected. In addition, the prior art also adds 2 antennas on the basis of 4 antennas to obtain a 6-antenna terminal device. 2 antennas of the 6-antenna terminal device are used for 4G communication, and 4 antennas are used for 5G communication, so the 6-antenna terminal device can adopt the 1T4R round-trip mechanism. However, the space of the terminal device is limited, and the addition of 2 antennas will result in a smaller space for the two antennas, poor antenna performance, and will also increase the cost of the terminal device.

[0046] Furthermore, in response to the defects of the prior art, an embodiment of the present application provides a wireless communication device, which can be set in the terminal device 140. Without interrupting the 4G service, a 1T4R round-robin strategy can be used to transmit SRS to ensure the downlink peak rate.

[0047] Figure 2 A schematic diagram of the structure of a wireless communication device according to an embodiment of the present application is exemplified. Figure 2 The wireless communication device 200 shown is only one example of a wireless communication device, and the wireless communication device 200 may have more or fewer components than shown in the figure, may combine two or more components, or may have a different configuration of components. Figure 2The various components shown in the drawings may be implemented in hardware, software, or a combination of hardware and software, including one or more signal processing and / or application specific integrated circuits.

[0048] The wireless communication device 200 may include: a processing circuit 210 , a radio frequency front-end module 220 and an antenna group 230 .

[0049] Exemplarily, the processing circuit 210 may be coupled to the RF front-end module 220 , and the RF front-end module 220 may be coupled to the antenna group 230 .

[0050] Exemplarily, the processing circuit 210 may include a radio frequency processing circuit such as a transceiver, which may be used to receive a baseband signal from the baseband processing circuit and perform radio frequency modulation on the baseband signal, obtain a radio frequency modulated signal, and send it to the radio frequency front-end module. The radio frequency processing circuit may also be used to receive a signal from the radio frequency front-end module, perform radio frequency demodulation on the signal, obtain a radio frequency demodulated signal, and send it to the baseband processing circuit for processing.

[0051] Exemplarily, the processing circuit 210 may include a baseband processing circuit and a radio frequency processing circuit. The baseband processing circuit is coupled to the radio frequency processing circuit, and the baseband processing circuit may be used to receive the original signal from the central processing circuit, and perform baseband modulation on the original signal to obtain the baseband signal and send it to the radio frequency processing circuit. The radio frequency processing circuit may be used to receive the baseband signal from the baseband processing circuit, and perform radio frequency modulation on the baseband signal, and obtain the radio frequency modulated signal and send it to the radio frequency front-end module 220. The radio frequency processing circuit may be used to receive a signal from the radio frequency front-end module 220, perform radio frequency demodulation on the signal, obtain the radio frequency demodulated signal and send it to the baseband processing circuit. The baseband processing circuit may also be used to receive the radio frequency demodulated signal from the radio frequency processing circuit, and perform baseband demodulation on the radio frequency demodulated signal, obtain the baseband demodulated signal and send it to the central processing unit circuit for processing.

[0052] Exemplarily, the processing circuit 210 may include a central processing circuit, a baseband processing circuit, and a radio frequency processing circuit. The central processing circuit may be coupled to a baseband processor, and the baseband processing circuit may be coupled to a radio frequency processing circuit. The central processing circuit may be used to generate or obtain an original signal and send it to the baseband processing circuit. The baseband processing circuit may be used to receive the original signal from the central processing circuit and perform baseband modulation on the original signal to obtain a baseband signal and send it to the radio frequency processing circuit. The radio frequency processing circuit may be used to perform radio frequency modulation on the baseband signal to obtain a radio frequency modulated signal and send it to the radio frequency front-end module 220. The radio frequency processing circuit may also be used to receive a signal from the radio frequency front-end module 220, perform radio frequency demodulation on the signal, obtain a radio frequency demodulated signal and send it to the baseband processing circuit. The baseband processing circuit may also be used to perform baseband demodulation on the radio frequency demodulated signal to obtain a baseband demodulated signal and send it to the central processing circuit. The central processing circuit may also be used to process and output the baseband demodulated signal. For example, the wireless communication device 200 is a terminal device, and the baseband demodulated signal is a voice signal, and the central processing circuit can output the voice signal to the speaker for playback. For another example, the baseband demodulated signal is text / picture, and the central processing circuit can output the text / picture to the display component for display, and so on.

[0053] Exemplarily, the antenna group 230 may be used to transmit and receive radio frequency signals.

[0054] Exemplarily, the antenna group 230 may include a first antenna 231 , a second antenna 232 , a third antenna 233 , a fourth antenna 234 , and a fifth antenna 235 .

[0055] Exemplarily, the RF front-end module 220 can be used to receive signals from the processing circuit 210 and convert the received signals into RF signals, which are then transmitted through an antenna; it can also be used to receive RF signals from an antenna and perform filtering, amplification, and other processing on the signals, and input the processed signals into the processing circuit 210.

[0056] Exemplarily, the RF front-end module 220 may include: a combiner 221 , a first switch 222 , and a second switch 223 .

[0057] Exemplarily, the combiner 221 may include a plurality of bidirectional ports, which may be used for input and output of signals.

[0058] Exemplarily, the combiner 221 may include two groups of ports: a first group of ports and a second group of ports. When the first group of ports is used for input, the second group of ports is used for output. When the second group of ports is used for input, the first group of ports is used for output. For example, when the wireless communication device 200 transmits a signal, the first group of ports may be used for input, and the second group of ports may be used for output. When the antenna of the wireless communication device 200 receives a signal, the second group of ports may be used for input, and the first group of ports may be used for output.

[0059] Exemplarily, when there are multiple ports used as inputs in the combiner 221 and only one port used as outputs, the combiner 221 can combine the signals input from the multiple ports to obtain one signal and output it from the output port.

[0060] Exemplarily, when there are multiple output ports in the combiner 221 and only one input port, the combiner 221 can output the signal received from the one input port from the multiple output ports respectively.

[0061] Exemplarily, the combiner 221 includes but is not limited to one of the following: a frequency synthesizer (such as a Diplexer, a Triplexer, an Extractor, etc.) and a switch with a Multi-On function.

[0062] For example, the first switch 222 may include a data port (eg, Figure 2 Port p1, port p2, and port p3) and control port ( Figure 2 The data port may include a plurality of bidirectional ports, which may be used to input and output interactive signals between the wireless communication device 200 and other devices. The control port may be used to input a control signal for the first switch 222, and the control signal may be used to control the state of the first switch 222.

[0063] Exemplarily, the data port of the first switch 222 may include two groups: a third group of ports and a fourth group of ports. When the third group of ports is used for input, the fourth group of ports is used for output. When the fourth group of ports is used for input, the third group of ports is used for output. For example, when the wireless communication device 200 transmits a signal, the third group of ports may be used for input, and the fourth group of ports may be used for output. When the antenna of the wireless communication device 200 receives a signal, the fourth group of ports may be used for input, and the third group of ports may be used for output.

[0064] Exemplarily, the third group of ports may include multiple data ports, and the fourth group of ports may also include multiple data ports. The number of data ports included in the third group of ports and the number of data ports included in the fourth group of ports may be the same or different, and may be determined according to actual needs, and the embodiments of the present application do not limit this. For example, Figure 2 In the embodiment, the third group of ports may include one data port such as port p1, and the fourth group of ports may include two data ports such as ports p2 and p3. Each data port included in the third group of ports may be connected to each data port included in the fourth group of ports. The state of the first switch 222 may refer to the state in which a data port in the third group of ports is connected to a data port in the fourth group of ports. The state of the first switch 222 may include multiple states, and at least one data port in the two pairs of ports that are connected is different in two different states. For example, Figure 2 The first switch 222 may include two states. The first state may be: the data port coupled to the combiner 221 in the third group of ports and the port coupled to the first antenna 231 in the fourth group of ports are turned on, that is, ports p1 and p2 are turned on. The second state may be: the data port coupled to the combiner 221 in the third group of ports and the port coupled to the second antenna 232 in the fourth group of ports are turned on, that is, ports p1 and p3 are turned on.

[0065] Exemplarily, the second switch 223 may include a data port (eg Figure 2 Port p4, port p5, port p6, port p7, and port p8) and control port ( Figure 2 223). Exemplarily, the data ports of the second switch 223 may include two groups: a fifth group of ports (such as including port p4) and a sixth group of ports (such as including ports p5, p6, p7 and p8). When the fifth group of ports is used for input, the sixth group of ports is used for output. When the sixth group of ports is used for input, the fifth group of ports is used for output. The description of the second switch 223 may refer to the description of the first switch 222 above, which will not be repeated here.

[0066] Exemplarily, in the wireless communication device 200, four antennas may be allocated for the first network communication, and two antennas may be allocated for the second network communication; wherein the first network communication and the second network communication share one antenna.

[0067] Exemplarily, the first antenna 231 and the second antenna 232 may be allocated for the second network communication, and the first antenna 231, the third antenna 233, the fourth antenna 234, and the fifth antenna 235 may be allocated for the first network communication. In other words, the first network communication and the second network communication reuse the first antenna 231. Of course, the first antenna 231 and the second antenna 232 may also be allocated for the second network communication, and the second antenna 232, the third antenna 233, the fourth antenna 234, and the fifth antenna 235 may be allocated for the first network communication. In other words, the first network communication and the second network communication reuse the second antenna 232, which is not limited in the embodiments of the present application.

[0068] Exemplarily, the first network and the second network are two networks using different mobile communication technologies; for example, the first network is a 5G network and the second network is a 4G network. The frequency bands corresponding to the first network and the second network may be different. For example, when the first network is a 5G network, the corresponding frequency band may be 2515-2675MHz (the corresponding frequency band number is n41), and when the second network is a 4G network, the corresponding frequency band may be 1710-2690MHz (the corresponding frequency band may be MHB (MB (Medium Frequency, medium frequency) & HB (High Frequency, high frequency), medium and high frequency), and the corresponding frequency band numbers may include B3, B39). The first network and the second network may frequency-division multiplex the first antenna 231 or the second antenna 232.

[0069] Exemplarily, the processing circuit 210 may be coupled to the combiner 221 , the second antenna 232 , the third antenna 233 , the fourth antenna 234 , and the fifth antenna 235 . The combiner 221 is coupled to the first antenna 231 .

[0070] Exemplarily, if the first network communication and the second network communication reuse the first antenna 231, the processing circuit 210 can be used to transmit the first signal from the third antenna 233, the fourth antenna 234 and the fifth antenna 235 in turn, and send the first signal and the second signal to the combiner, and transmit the first signal and the second signal from the first antenna 231 through the combiner 221. The first signal is the SRS of the first network, and the second signal is the signal of the second network.

[0071] Exemplarily, if the first network communication and the second network communication multiplex the second antenna 232, the processing circuit 210 may be used to transmit the first signal from the third antenna 233, the fourth antenna 234, and the fifth antenna 235 in turn, and send the first signal and the second signal to the combiner, and transmit the first signal and the second signal from the second antenna 232 through the combiner 221. The processing circuit 210 may determine whether the performance of the first antenna 231 is better than the performance of the second antenna 232 when transmitting the second signal and transmitting the first signal in turn. If the performance of the first antenna 231 is better than the performance of the second antenna 232, the first signal and the second signal are transmitted from the first antenna 231 through the combiner 221. If the performance of the second antenna 232 is better than the performance of the first antenna 231, the first signal and the second signal are transmitted from the second antenna 232 through the combiner 221.

[0072] Exemplarily, the processing circuit 210 may be coupled to the first switch 222, the second switch 223, and the combiner 221, wherein different ports of the processing circuit 210 may be coupled to the combiner 221, the first switch 222, and the second switch 223, respectively. The second switch 223 may be coupled to the third antenna 233, the fourth antenna 234, the fifth antenna 235, and the combiner 221, wherein different ports of the second switch 223 may be coupled to the third antenna 233, the fourth antenna 234, the fifth antenna 235, and the combiner 221, respectively. The combiner 221 may be coupled to the first switch 222. The first switch 222 may be coupled to the first antenna 231 and the second antenna 232, wherein different ports of the first switch 222 may be coupled to the first antenna 231 and the second antenna 232, respectively.

[0073] Exemplarily, different ports of the processing circuit 210 can be respectively coupled to the first group of ports of the combiner 221, the control port of the first switch 222, and the control port and data port of the second switch 223. For example, a port of the processing circuit 210 can be coupled to the fifth group of ports of the second switch 223, such as port p4.

[0074] Exemplarily, a port in the second group of ports of the combiner 221 may be coupled to a port in the third group of ports of the first switch 222 , such as the port p1 .

[0075] Exemplarily, two data ports of the fourth group of ports of the first switch 222, such as port p2 and port p3, may be coupled to the first antenna 231 and the second antenna 232, respectively.

[0076] Exemplarily, the four data ports of the sixth group of ports of the second switch 223, such as ports p5, p6, p7 and p8, can be respectively coupled to the third antenna 233, the fourth antenna 234, the fifth antenna 235 and the ports in the first group of ports of the combiner 221.

[0077] Exemplarily, if the first network communication and the second network communication reuse the first antenna 231, the processing circuit 210 can be used to control the state of the second switch 223 to transmit the first signal in turn to the third antenna 233, the fourth antenna 234 and the fifth antenna 235, and to control the state of the second switch 223 to send the first signal to the combiner 221, and to send the second signal to the combiner 221, and to control the state of the first switch 222 to transmit the first signal and the second signal from the first antenna 231 through the combiner 221 and the first switch 222 in turn.

[0078] Exemplarily, if the first network communication and the second network communication multiplex the second antenna 232, the processing circuit 210 can be used to control the state of the second switch 223 to transmit the first signal in turn through the third antenna 233, the fourth antenna 234 and the fifth antenna 235, and control the state of the second switch 223 to send the first signal to the combiner 221, and send the second signal to the combiner 221, and control the state of the first switch 222, and transmit the first signal and the second signal from the second antenna 232 through the combiner 221 and the first switch 222 in sequence. Among them, the processing circuit 210 can determine whether the performance of the first antenna 231 is better than the performance of the second antenna 232 when transmitting the second signal and transmitting the first signal in turn. If the performance of the first antenna 231 is better than the performance of the second antenna 232, the processing circuit 210 can be used to control the states of the first switch 222 and the second switch 223, and transmit the first signal and the second signal from the first antenna 231 in sequence through the second switch 223, the combiner 221 and the first switch 222. If the performance of the second antenna 232 is better than that of the first antenna 231 , the processing circuit 210 can be used to control the states of the first switch 222 and the second switch 223 , and transmit the first signal and the second signal from the second antenna 232 through the second switch 223 , the combiner 221 and the first switch 222 in sequence.

[0079] To facilitate understanding by persons skilled in the art, the following description is given by taking the transmission of the first signal and the second signal from the first antenna 231 as an example.

[0080] Please refer to Figure 3 , Figure 3 The following is a schematic diagram showing the switch states corresponding to the four-way SRS transmission of the wireless communication device according to the embodiment of the present application. For example, the wireless communication device 200 can transmit the SRS in turn through the following four channels:

[0081] Path 31: processing circuit 210 → second switch 223 → third antenna 233;

[0082] Path 32: processing circuit 210 → second switch 223 → fourth antenna 234;

[0083] Path 33: processing circuit 210 → second switch 223 → fifth antenna 235;

[0084] Path 34: processing circuit 210 → second switch 223 → combiner 221 → first switch 222 → first antenna 231 .

[0085] Exemplarily, the first signal can be transmitted from the third antenna 233 through the path 31. Figure 3 31: The processing circuit 210 may send a first signal to the second switch 223, and may send a first control signal to the second switch 223, so that the second switch 223 switches on the port p6 coupled to the third antenna 233 and the port p4 coupled to the processing circuit 210 in the second switch 223 according to the first control signal. Then, the second switch 223 may transmit the first signal received from the processing circuit 210 from the third antenna 233.

[0086] Exemplarily, the first signal may be transmitted from the fourth antenna 234 through the path 22. Figure 3 32: The processing circuit 210 sends the first signal to the second switch 223, and can send the second control signal to the second switch 223, so that the second switch 223, according to the second control signal, turns on the port p7 of the second switch 223 coupled to the fourth antenna 234 and the port p4 of the second switch 223 coupled to the processing circuit 210. Then, the second switch 223 can transmit the first signal received from the processing circuit 210 from the fourth antenna 234.

[0087] Exemplarily, the first signal can be transmitted from the fifth antenna 235 through the path 23. Figure 3 33: The processing circuit 210 sends the first signal to the second switch 223, and can send the third control signal to the second switch 223, so that the second switch 223, according to the third control signal, turns on the port p8 of the second switch 223 coupled to the fifth antenna 235 and the port p4 of the second switch 223 coupled to the processing circuit 210. Then, the second switch 223 can transmit the first signal received from the processing circuit 210 from the fifth antenna 235.

[0088] Exemplarily, the first signal can be transmitted from the first antenna 231 through the path 24. Figure 334: The processing circuit 210 sends the first signal to the second switch 223. And the fourth control signal can be sent to the second switch 223, so that the second switch 223 can connect the port p5 coupled to the combiner 221 in the second switch 223 and the port p4 coupled to the processing circuit 210 in the second switch 223 according to the control signal. And the fifth control signal can be sent to the first switch 222, so that the first switch 222 can connect the port p2 coupled to the first antenna 231 in the first switch 222 and the input port p1 coupled to the combiner 221 in the first switch 222 according to the fifth control signal. Then the second switch 223 can send the first signal to the combiner 221, and the combiner 221 sends the first signal to the first switch 222, and then the first switch 222 can transmit the first signal from the first antenna 231.

[0089] Exemplarily, the timing of the processing circuit 210 sending the control signal to the second switch 223 can be set as required, and the embodiment of the present application does not limit this. Among them, it can be any time from the processing circuit 210 obtaining the first signal to sending the first signal to the second switch 223.

[0090] For example, the timing when the processing circuit 210 sends the control signal to the first switch 222 can be set as required, and the embodiment of the present application does not limit this. It can be any time from when the processing circuit 210 obtains the first signal to when the first signal is sent to the first switch 222.

[0091] It should be noted that the embodiment of the present application does not limit the order in which the wireless communication device transmits the first signal in turn, and can be set as required, and the embodiment of the present application does not limit this. For example, it can be transmitted in turn in the order of the first antenna 231, the third antenna 233, the fourth antenna 234 and the fifth antenna 235, that is, through the path 34, the path 31, the path 32 and the path 33 in turn, the SRS is transmitted in turn. For another example, the third antenna 233, the fourth antenna 234, the fifth antenna 235 and the first antenna 231 are transmitted in turn, that is, through the path 31, the path 32, the path 33 and the path 34 in turn, and so on.

[0092] When the wireless communication device sends a signal of the second network (for the convenience of subsequent description, it can be called a second signal), the second signal can be transmitted from the first antenna 231 through the processing circuit 210 → combiner 221 → first switch 222 → first antenna 231.

[0093] Exemplarily, the processing circuit 210 may send the second signal to the combiner 221, and control the state of the first switch 222 to transmit the second signal from the first antenna 231. Figure 334: The processing circuit 210 may send the second signal to the combiner 221, and send the sixth control signal to the first switch 222, so that the first switch 222 switches on the port p2 coupled to the first antenna 231 and the port p1 coupled to the combiner 221 in the first switch 222 according to the sixth control signal. Then the combiner 221 may send the second signal to the first switch 222, and then the first switch 222 may transmit the second signal from the first antenna 231.

[0094] For example, when the wireless communication device is about to send the first signal to the first antenna 231, if the wireless communication device is transmitting the second signal, the process of the wireless communication device sending the first signal and the second signal can refer to Figure 3 34: When the wireless communication device is about to transmit the first signal to the first antenna 231 in turn, if the wireless communication device is transmitting the second signal, the combiner 221 can receive the first signal sent by the processing circuit 210 through the port coupled to the second switch 223, and receive the second signal sent by the processing circuit 210 through the port coupled to the processing circuit 210. Then the combiner 221 can combine the first signal with the second signal to obtain a combined signal, and input it to the first switch 222. After the first switch 222 turns on the port p2 coupled to the first antenna 231 in the first switch 222 and the port p1 coupled to the combiner 221 in the first switch 222 according to the fifth control signal sent by the processing circuit 210, the first switch 222 can transmit the combined signal through the first antenna 231. Then, the first signal and the second signal are both transmitted from the first antenna 231. In this way, the SRS of the first network is transmitted in turn from four channels, the downlink peak rate is improved, and the service of the second network will not be interrupted, thereby improving the user experience.

[0095] Exemplarily, when the wireless communication device is about to send the first signal to the first antenna 231, if the wireless communication device has not sent the signal of the second network, the combiner 221 can directly send the first signal received from the second switch 223 to the first switch 222, and transmit the first signal from the first antenna 231. Figure 3 34 in which a first signal is transmitted from the first antenna 231.

[0096] Compared with the prior art wireless communication device with four antennas that implements two-way SRS transmission, the five-antenna wireless communication device in the embodiment of the present application can implement four-way SRS transmission, which can improve the downlink peak rate.

[0097] In addition, terminal devices of different gears (e.g., price) have different SRS round-robin rules. The higher the gear of a terminal device, the higher the SRS round-robin rule requirements for the wireless communication device therein (i.e., the more antennas are used to round-robin SRS). A terminal device using 4 antennas in the prior art cannot meet the high-grade requirements, while a terminal device using the wireless communication device of an embodiment of the present application can meet the high-grade requirements.

[0098] Compared with the existing 6-antenna wireless communication device that implements 4-way round-robin SRS, the embodiment of the present application implements 4-way round-robin SRS for a 5-antenna wireless communication device. Due to the space limitation of the terminal device, the embodiment of the present application adds one antenna, which occupies more space than each of the two antennas added in the existing 6-antenna terminal device, thereby enabling better antenna performance and ensuring mobile data services.

[0099] An application scenario of the embodiment of the present application may be: the first network is 5G, the second network is 4G, the first signal is 5G SRS, and the second signal is a 4G signal. Among them, the first antenna 231 and the second antenna 232 are used for 4G communication, the first antenna 231, the third antenna 233, the fourth antenna 234 and the fifth antenna 235 can be used for 5G communication, and the first antenna 231 is an antenna multiplexed for 4G communication and 5G communication. Figure 3 , the process of the wireless communication device sending 5G SRS in turn can be: the processing circuit 210 can send the 5G SRS to the second switch 223, and then control the port p4 of the second switch 223 to be connected with the port p6, the port p7 and the port p8 in turn, and the 5G SRS is transmitted from the third antenna 233, the fourth antenna 234 and the fifth antenna 235 in turn. And the port p4 of the second switch 223 is controlled to be connected with the port p5 to send the 5G SRS to the combiner 221. At this time, if the wireless communication device is sending a 4G signal, the combiner 221 can receive the 4G signal and the 5G SRS. Then the combiner 221 can combine the 4G and 5GSRS to obtain a combined signal, and input it to the first switch 222. Then the processing circuit 210 can control the ports p1 and p2 of the first switch 222 to be connected, and transmit the combined signal through the first antenna 231. Then, both 4G signals and 5G SRS can be transmitted, so as to realize the transmission of 5G SRS from four channels in turn, improve the downlink peak rate of 5G, and will not interrupt 4G services.

[0100] Exemplarily, the first antenna 231 may be a main antenna, the second antenna 232 may be a diversity antenna, and the third antenna 233 and the fourth antenna 234 may be MIMO (multiple-in multipleout) antennas.

[0101] Exemplarily, the wireless communication device may transmit a signal of the second network from the first antenna 231, or may transmit a signal of the second network from the second antenna 232, which is specifically determined according to the performance of the first antenna 231 and the second antenna 232, and the embodiment of the present application does not limit this. If the performance of the second antenna 232 is better than that of the first antenna 231, the signal of the second network may be transmitted from the second antenna 232. If the performance of the first antenna 231 is better than that of the second antenna 232, the signal of the second network may be transmitted from the first antenna 231. And the signal of the second network may be received from the first antenna 231 and the second antenna 232.

[0102] Exemplarily, the wireless communication device may transmit other signals of the first network from the third antenna 233, or may transmit other signals of the first network from the fourth antenna 234, which is specifically determined according to the performance of the third antenna 233 and the fourth antenna 234, and the embodiment of the present application does not limit this. If the performance of the third antenna 233 is better than that of the fourth antenna 234, other signals of the first network may be transmitted from the third antenna 233. If the performance of the fourth antenna 234 is better than that of the third antenna 233, other signals of the first network may be transmitted from the fourth antenna 234. And other signals of the first network may be received from the first antenna 231, the third antenna 233, the fourth antenna 234 and the fifth antenna 235. The other signals of the first network may include signals other than the SRS of the first network.

[0103] Figure 4 A schematic diagram of the structure of another wireless communication device according to an embodiment of the present application is exemplified. Figure 4 The wireless communication device 200 shown is only one example of a wireless communication device, and the wireless communication device 200 may have more or fewer components than shown in the figure, may combine two or more components, or may have a different configuration of components. Figure 4 The various components shown in the drawings may be implemented in hardware, software, or a combination of hardware and software, including one or more signal processing and / or application specific integrated circuits.

[0104] The wireless communication device 200 may include: a processing circuit 210 , a radio frequency front-end module 220 and an antenna group 230 .

[0105] Exemplarily, the processing circuit 210 may be coupled to the RF front-end module 220 , and the RF front-end module 220 may be coupled to the antenna group 230 .

[0106] Exemplarily, the antenna group 230 may include a first antenna 231 , a second antenna 232 , a third antenna 233 , a fourth antenna 234 , and a fifth antenna 235 .

[0107] Exemplarily, the RF front-end module 220 may include: a combiner 221 , a first switch 222 , and a second switch 223 .

[0108] Exemplarily, the processing circuit 210 may be coupled to the second switch 223, the first switch 222, and the combiner 221. The second switch 223 may be coupled to the third antenna 233, the fourth antenna 234, the fifth antenna 235, and the combiner 221. The combiner 221 may be coupled to the first switch 222, and the first switch 222 may be coupled to the first antenna 231 and the second antenna 232.

[0109] Exemplarily, the first switch 222 may be an antenna switching switch, which may be referred to as a first antenna switching switch. The second switch 223 may include a second antenna switching switch 2231, an SRS switch 2232, and a transceiver switch 2233. The second antenna switching switch 2231 is coupled to the third antenna 233 and the SRS switch 2232, the SRS switch 2232 is coupled to the fourth antenna 234, the transceiver switch 2233, and the combiner 221, and the transceiver switch 2233 is coupled to the fifth antenna 235. Different ports of the SRS switch 2232 may be coupled to the fourth antenna 234, the transceiver switch 2233, and the combiner 221, respectively.

[0110] Exemplarily, the second antenna switch 2231 may include a data port (eg, Figure 4 ports p4, p6, and p9) and the control port ( Figure 4 The data port of the second antenna switching switch 2231 may include two groups: a seventh group of ports (such as including port p4) and an eighth group of ports (such as including ports p6 and p9). When the seventh group of ports is used for input, the eighth group of ports is used for output. When the eighth group of ports is used for input, the seventh group of ports is used for output. The description of the second antenna switching switch 2231 may refer to the description of the first switch 222 above, which will not be repeated here.

[0111] For example, the SRS switch 2232 may include a data port (eg, Figure 4 ports p5, p7, p10, and p11) and the control port ( Figure 4 The data port may include a plurality of bidirectional ports, which may be used to input and output interactive signals between the wireless communication device 200 and other devices. The control port may be used to input a control signal for the SRS switch 2232, and the control signal may be used to control the state of the SRS switch 2232.

[0112] Exemplarily, the data port of the SRS switch 2232 may include two groups: a ninth group of ports and a tenth group of ports. When the ninth group of ports is used for input, the tenth group of ports is used for output. When the tenth group of ports is used for input, the ninth group of ports is used for output. For example, when the wireless communication device 200 transmits a signal, the ninth group of ports may be used for input, and the tenth group of ports may be used for output. When the antenna of the wireless communication device 200 receives a signal, the tenth group of ports may be used for input, and the ninth group of ports may be used for output.

[0113] Exemplarily, the ninth group of ports may include multiple data ports, and the tenth group of ports may also include multiple data ports. The number of data ports included in the ninth group of ports and the number of data ports included in the tenth group of ports may be the same or different, and may be determined according to actual needs, and the embodiments of the present application do not limit this. For example, Figure 4 In the embodiment, the ninth group of ports may include one data port such as port p10, and the tenth group of ports may include three data ports such as ports p5, p7, and p11. Each data port included in the ninth group of ports may be connected to each data port included in the tenth group of ports. The state of the SRS switch 2232 may refer to the state in which the data ports in the ninth group of ports are connected to the data ports in the tenth group of ports. The state of the SRS switch 2232 may include multiple states, and at least one data port in the two pairs of ports that are connected is different in two different states. For example, Figure 4 The SRS switch 2232 may include three states: the first state may be: the data port coupled to the second antenna switching switch 2231 in the ninth group of ports and the port coupled to the fourth antenna 234 in the eighteenth group of ports are connected, that is, port p10 is connected to port p7. The second state may be: the data port coupled to the second antenna 232 in the ninth group of ports and the port coupled to the transceiver switch 2233 in the tenth group of ports are connected, that is, port p10 is connected to port p11. The third state may be: the data port coupled to the second antenna switching switch 2231 in the ninth group of ports and the port coupled to the combiner 221 in the tenth group of ports are connected, that is, port p10 is connected to port p5.

[0114] For example, the transceiver switch 2233 may include a data port (eg, Figure 4 ports p8, p12, and p13) and the control port ( Figure 4 The data port can be used to input and / or output interactive signals between the wireless communication device 200 and other devices. The control port can be used to input control signals for the transceiver switch 2233, and the control signal can be used to control the state of the transceiver switch 2233.

[0115] Exemplarily, the transceiver switch 2233 includes a data port such as port p8 coupled to the fifth antenna 235, which can be a bidirectional port; thus, when the wireless communication device 200 transmits a signal, the port can be used for output, and when the antenna of the wireless communication device 200 receives a signal, the port can be used for input. The transceiver switch 2233 also includes a data port such as port p12 coupled to the SRS switch 2232, which can be a unidirectional port or a bidirectional port, and is used to receive the signal sent by the SRS switch 2232. In addition, the transceiver switch 2233 can also include a data port such as port p13 coupled to the processing circuit 210, which can be a unidirectional port or a bidirectional port, and is used to send the signal to the processing circuit 210 (in Figure 4 not shown).

[0116] Exemplarily, the processing circuit 210 may be coupled to the second antenna switch 2231 , wherein the processing circuit 210 may be coupled to the seventh group of ports of the second antenna switch 2231 , such as port p4 , and may be coupled to the control port of the second antenna switch 2231 .

[0117] Exemplarily, the processing circuit 210 may be coupled to the SRS switch 2232 . The processing circuit 210 may be coupled to a control port of the SRS switch 2232 .

[0118] Exemplarily, the processing circuit 210 may be coupled to the transceiver switch 2233 . The processing circuit 210 may be coupled to a control port of the transceiver switch 2233 .

[0119] Exemplarily, two ports in the sixth group of ports of the second antenna switching switch 2231, such as ports p6 and p9, can be respectively coupled to the third antenna 233 and a port in the seventh group of ports of the SRS switch 2232, such as p10. Three ports in the eighth group of ports of the SRS switch 2232, such as ports p7, p11, and p5, can be respectively coupled to the fourth antenna 234, port p12 of the transceiver switch 2233, and a port in the first group of ports of the combiner 221.

[0120] Exemplarily, the four transmission paths corresponding to the four-way round-robin SRS may be:

[0121] Processing circuit 210 → second antenna switch 2231 → third antenna 233;

[0122] Processing circuit 210 → second antenna switch 2231 → SRS switch 2232 → fourth antenna 234;

[0123] Processing circuit 210 → second antenna switch 2231 → SRS switch 2232 → transceiver switch 2233 → fifth antenna 235;

[0124] Processing circuit 210 → second antenna switch 2231 → SRS switch 2232 → combiner 221 → first switch 222 → first antenna 231 .

[0125] Exemplarily, the first signal can be transmitted from the third antenna 233 through the path of processing circuit 210 → second antenna switch 2231 → third antenna 233. The process can be as follows: the processing circuit 210 can send the first signal to the second antenna switch 2231, and can send the first antenna switching control signal to the second antenna switch 2231, so that the second antenna switch 2231, according to the first antenna switching control signal, turns on the port p6 coupled to the third antenna 233 in the second antenna switch 2231 and the port p4 coupled to the processing circuit 210 in the second antenna switch 2231. Then, the second antenna switch 2231 can transmit the first signal received from the processing circuit 210 from the third antenna 233.

[0126] Exemplarily, the first signal can be transmitted from the fourth antenna 234 through the path of processing circuit 210→second antenna switch 2231→SRS switch 2232→fourth antenna 234. The process can be as follows: the processing circuit 210 sends the first signal to the second antenna switch 2231. And the second antenna switching control signal can be sent to the second antenna switch 2231, so that the second antenna switch 2231, according to the second antenna switching control signal, turns on the port p9 coupled to the SRS switch 2232 in the second antenna switch 2231 and the port p4 coupled to the processing circuit 210 in the second antenna switch 2231. And the first SRS state control signal can be sent to the SRS switch 2232, so that the SRS switch 2232, according to the first SRS state control signal, turns on the port p7 coupled to the fourth antenna 234 in the SRS switch 2232 and the port p10 coupled to the second antenna switch 2231 in the SRS switch 2232. Then, the second antenna switch 2231 may send the first signal to the SRS switch 2232 , and the SRS switch 2232 may transmit the first signal from the fourth antenna 234 .

[0127] Exemplarily, the first signal can be transmitted from the fifth antenna 235 through the path of processing circuit 210 → second antenna switch 2231 → SRS switch 2232 → transceiver switch 2233 → fifth antenna 235. The process can be as follows: the processing circuit 210 sends the first signal to the second antenna switch 2231. And the third antenna switching control signal can be sent to the second antenna switch 2231, so that the second antenna switch 2231 turns on the port p9 coupled to the SRS switch 2232 in the second antenna switch 2231 and the port p4 coupled to the processing circuit 210 in the second antenna switch 2231 according to the third antenna switching control signal.

The process can be as follows: the processing circuit 210 sends the first signal to the second antenna switch 2231. And the fourth antenna switching control signal can be sent to the second antenna switch 2231, so that the second antenna switch 2231 turns on the port p9 coupled to the SRS switch 2232 in the second antenna switch 2231 and the port p4 coupled to the processing circuit 210 in the second antenna switch 2231 according to the fourth antenna switching control signal. And the third SRS state control signal can be sent to the SRS switch 2232, so that the SRS switch 2232 turns on the port p5 coupled to the combiner 221 and the port p10 coupled to the second antenna switch 2231 in the SRS switch 2232 according to the third SRS state control signal. And the fifth antenna switching control signal can be sent to the first antenna switching switch, so that the first antenna switching switch turns on the port p2 coupled to the first antenna 231 and the port p1 coupled to the combiner 221 in the first antenna switching switch according to the fifth antenna switching control signal.

It can be any time from when the processing circuit 210 obtains the first signal to when the first signal is sent to the first switch 222.

[0131] For example, the timing of the processing circuit 210 sending the control signal to the SRS switch 2232 can be set as required, and the embodiment of the present application does not limit this.

[0134] Figure 5 A schematic diagram of the structure of another wireless communication device according to an embodiment of the present application is exemplified. Figure 5 The wireless communication device 200 shown is only one example of a wireless communication device, and the wireless communication device may have more or fewer components than shown in the figure, may combine two or more components, or may have a different configuration of components. Figure 5 The various components shown in the drawings may be implemented in hardware, software, or a combination of hardware and software, including one or more signal processing and / or application specific integrated circuits.

[0135] The wireless communication device 200 may include: a processing circuit 210 , a radio frequency front-end module 220 and an antenna group 230 .

[0136] Exemplarily, the processing circuit 210 may be coupled to the RF front-end module 220 , and the RF front-end module 220 may be coupled to the antenna group 230 .

[0137] Exemplarily, the antenna group 230 may include a first antenna 231 , a second antenna 232 , a third antenna 233 , a fourth antenna 234 , and a fifth antenna 235 .

[0138] Exemplarily, the RF front-end module 220 may include: a combiner 221 , a first switch 222 , a second switch 223 , and a third switch 224 .

[0139] Exemplarily, the processing circuit 210 may be coupled to the second switch 223, the first switch 222, and the third switch 224. The second switch 223 may be coupled to the third antenna 233, the fourth antenna 234, the fifth antenna 235, and the combiner 221, and the third switch 224 may be coupled to the combiner 221 and the first switch 222. The combiner 221 may be coupled to the first switch 222, and the first switch 222 may be coupled to the first antenna 231 and the second antenna 232.

[0140] Exemplarily, the third switch 224 can be used to select a signal frequency band, and can also be used to select a signal transmission channel. For example, the wireless communication device 200 transmits a second signal, and the corresponding transmission channel may include: channel 51: third switch 224 → combiner 221 → first switch 222 → first antenna 231; channel 52: third switch 224 → first switch 222 → first antenna 231.

[0141] For example, the third switch 224 may include a data port (eg, Figure 5 ports p15 and p16 in the control port ( Figure 5 not shown) and band ports (such as Figure 5 f1, f2, f3 (such as 1710-1785MHz), f4 (such as 1800-1920MHz), f5, f6, f7 and f8). Among them, the data port can be a bidirectional port, which can be used to input and output interactive signals between the wireless communication device 200 and other devices. For example, when the wireless communication device 200 transmits a signal, ports p15 and p16 can be used for output, and when the antenna of the wireless communication device 200 receives a signal, ports p15 and p16 can be used for input. When the data port is connected to the frequency band port, frequency band selection can be achieved. When different data ports are connected to the frequency band ports, signal communication channel selection can be achieved. The control port can be used to input control signals, and the control signals can be used to control the state of the third switch 224. The state of the third switch 224 may include: the state in which the frequency band port and the data port are connected, and the two different states correspond to different data ports in the two pairs of ports that are connected. For example, Figure 5 The third switch 224 may include 16 states. The first state may be: port p15 is connected to port f1. The second state may be: port p15 is connected to port f2.... The eighth state may be: port p15 is connected to port f8. The ninth state may be: port p16 is connected to port f1. The tenth state may be: port p16 is connected to port f2..... The sixteenth state may be: port p16 is connected to port f8.

[0142] Exemplarily, when the wireless communication device 200 is in a scenario where the first network and the second network can be detected, such as an EN-DC scenario, the wireless communication device 200 can simultaneously perform the first network communication and the second network communication. At this time, the wireless communication device 200 can transmit the second signal through the third switch 224 → combiner 221 → first switch 222 → first antenna 231, so that the wireless communication device 200 does not interrupt the transmission of the second signal when transmitting the first signal in turn. And when the wireless communication device 200 is in other scenarios such as a scenario with only the second network, the wireless communication device 200 can transmit the second signal through the third switch 224 → first switch 222 → first antenna 231, so that the second signal does not need to pass through the combiner 221, reducing the loss of the second signal.

[0143] For ease of explanation, a scenario in which the first network and the second network can be detected may be referred to as a first communication scenario; and a scenario in which only the second network is detected may be referred to as a second communication scenario.

[0144] Exemplarily, when the wireless communication device 200 is in the first communication scenario, if the wireless communication device 200 is about to send the first signal to the first antenna 231, the processing circuit 210 may send the second signal to the third switch 224. And send the first frequency band control signal to the third switch 224, so that the third switch 224 turns on the frequency band port of the corresponding frequency band in the third switch 224, such as port f4, and the port coupled to the combiner 221 in the third switch 224, such as port p16, according to the first frequency band control signal. And the seventh control signal may be sent to the first switch 222, so that the first switch 222 turns on the port connected to the first antenna 231 in the first switch 222, such as port p2, and the port coupled to the combiner 221 in the first switch 222, such as port p1, according to the seventh control signal. At the same time, the processing circuit 210 can also send the first signal to the second switch 223, and can also send the eighth control signal to the second switch 223, so that the second switch 223, according to the eighth control signal, turns on the port p5 coupled to the combiner 221 in the second switch 223 and the port p4 coupled to the processing circuit 210 in the second switch 223. Then the third switch 224 can select the frequency band of the second signal, and send the second signal after the frequency band selection to the combiner 221, and the second switch 223 can send the first signal to the combiner 221. Then the combiner 221 can receive the second signal and the first signal after the frequency band selection, and then combine the second signal and the first signal after the frequency band selection to obtain a combined signal. Then the combiner 221 can send the combined signal to the first switch 222, and the first switch 222 transmits the second signal obtained by the frequency band selection from the first antenna 231.

[0145] Exemplarily, when the wireless communication device 200 is in the first communication scenario, if the first signal is not transmitted to the first antenna 231, the processing circuit 210 may send the second signal to the third switch 224, control the state of the third switch 224 to send the second signal to the combiner 221, and control the state of the first switch 222 to send the second signal from the first antenna 231.

[0146] Exemplarily, when the wireless communication device 200 is in the first communication scenario, if the wireless communication device 200 does not send the first signal to the first antenna 231, the processing circuit 210 may send the second signal to the third switch 224. And send the first frequency band control signal to the third switch 224, so that the third switch 224 turns on the frequency band port of the corresponding frequency band in the third switch 224, such as port f4, and the port coupled to the combiner 221 in the third switch 224, such as port p16, according to the first frequency band control signal. And the ninth control signal may be sent to the first switch 222, so that the first switch 222 turns on the port connected to the first antenna 231 in the first switch 222, such as port p2, and the port coupled to the combiner 221 in the first switch 222, such as port p1, according to the ninth control signal. Then, the third switch 224 may select the frequency band of the second signal, and send the second signal after the frequency band selection to the combiner 221. After receiving the second signal after the frequency band is selected, the combiner 221 may send the second signal to the first switch 222 , and the first switch 222 transmits the second signal obtained by the frequency band selection from the first antenna 231 .

[0147] Exemplarily, when the wireless communication device 200 is in the second communication scenario, the processing circuit 210 can send a second signal to the third switch 224, control the third switch 224 to send the second signal to the first switch 222, and control the state of the first switch 222 to transmit the second signal from the first antenna 231.

[0148] Exemplarily, the processing circuit 210 may send the second signal to the third switch 224. And send the second frequency band control signal to the third switch 224, so that the third switch 224 turns on the frequency band port of the corresponding frequency band in the third switch 224, such as port f2, and the port coupled to the combiner 221 in the third switch 224, such as port p15, according to the first frequency band control signal. And the tenth control signal may be sent to the first switch 222, so that the first switch 222 turns on the port connected to the first antenna 231 in the first switch 222, such as port p2, and the input port connected to the third switch 224 in the first switch 222, such as port p14, according to the tenth control signal. Then, after the third switch 224 selects the frequency band of the second signal, it may send the second signal after the frequency band selection to the first switch 222. Then, the first switch 222 may transmit the second signal obtained by the frequency band selection from the first antenna 231.

[0149] Exemplarily, after receiving the signal transmitted by the wireless communication device 200, the base station may respond and generate and transmit a corresponding response signal. In addition, the base station may also actively transmit a signal to the wireless communication device 200. Then the wireless communication device 200 may receive the signal transmitted by the base station through the antenna. For convenience, the signal transmitted by the base station of the second network when the wireless communication device 200 is in the first communication scenario may be referred to as the third signal. And the signal transmitted by the base station of the second network when the wireless communication device 200 is in the second communication scenario may be referred to as the fourth signal.

[0150] Exemplarily, the path for the wireless communication device 200 to receive the third signal corresponds to the path for the wireless communication device 200 to transmit the second signal when the wireless communication device 200 is in the first communication scenario, and may be: first antenna 231→first switch 222→combiner 221→third switch 224→processing circuit 210. The path for the wireless communication device 200 to receive the fourth signal corresponds to the path for the wireless communication device 200 to transmit the second signal in the second communication scenario, and may be: first antenna 231→first switch 222→third switch 224→processing circuit 210, to obtain the fourth signal.

[0151] Please refer to Figure 5, exemplarily, when the wireless communication device 200 is in the first communication scenario, the first antenna 231 of the wireless communication device 200 can receive the third signal transmitted by the base station, and then the third signal can be sent to the first switch 222. Since the wireless communication device 200 is in the first communication scenario, the port coupled to the combiner 221 in the first switch 222, such as port p1, and the port coupled to the first antenna 231 in the first switch 222, such as port p2, are conductive, the combiner 221 can receive the third signal through the first switch 222. Then the combiner 221 can send the third signal to the third switch 224. Since the wireless communication device 200 is in the first communication scenario, the port coupled to the combiner 221 in the third switch 224, such as port p16, and the frequency band port in the third switch 224, such as port f4, are conductive, the third switch 224 can obtain the third signal from the combiner 221, and after performing frequency band selection on the third signal, send the third signal after frequency band selection to the processing circuit 210. The processing circuit 210 then processes the third signal after the frequency band selection, such as RF demodulation, baseband demodulation, etc.

[0152] Exemplarily, when the wireless communication device 200 is in the second communication scenario, the first antenna 231 of the wireless communication device 200 can receive the fourth signal transmitted by the base station, and then the fourth signal can be sent to the first switch 222. Since when the wireless communication device 200 is in the first communication scenario, the port such as p14 coupled to the port (such as p15) of the third switch 224 in the first switch 222, and the port such as p2 coupled to the first antenna 231 in the first switch 222 are conductive, and the port such as port p15 coupled to the port such as p14 of the first switch 224, and the frequency band port (such as port f2) in the third switch 224 are conductive, the third switch 224 can receive the fourth signal through the first switch 222. After the frequency band of the fourth signal is selected, the fourth signal after the frequency band selection is sent to the processing circuit 210. The processing circuit 210 then processes the fourth signal after the frequency band selection, such as RF demodulation, baseband demodulation, etc.

[0153] It should be noted that in the embodiment of the present application, when the wireless communication device 200 is in the first communication scenario, the wireless communication device 200 may also receive the third signal through the second antenna 232. Then, the third signal is sent to the processing circuit 210 through the second antenna 232 → the first switch 222 → the combiner 221 → the third switch 224 → the processing circuit 210, which will not be repeated here. And when the wireless communication device 200 is in the second communication scenario, the wireless communication device 200 may also receive the fourth signal through the second antenna 232. Then, the fourth signal is sent to the processing circuit 210 through the second antenna 232 → the first switch 222 → the third switch 224 → the processing circuit 210, which will not be repeated here. It can be determined specifically according to the performance of the first antenna 231 and the second antenna 232, and the embodiment of the present application does not limit this.

[0167] Exemplarily, the four transmission channels corresponding to the four-way round-robin transmission of SRS by the wireless communication device 200 may be:

[0168] Processing circuit 210 → PA2 (2285) → LB3 (2293) → transceiver switch TR1 (227) → second antenna switch 2231 → third antenna 233;

[0181] It should be noted that the embodiment of the present application does not limit the order in which the wireless communication device 200 transmits the first signal in turn, and can be set as required, and the embodiment of the present application does not limit this. For example, it can be transmitted in the order of the first antenna 231, the third antenna 233, the fourth antenna 234, and the fifth antenna 235. For another example, it can be transmitted in the order of the third antenna 233, the fourth antenna 234, the fifth antenna 235, and the first antenna 231, and so on.

[0182] For example, refer to Figure 6 , the wireless communication device 200 can transmit the second signal through the following two channels:

[0183] Processing circuit 210 → PA1 (2281) → duplexer 226 → combiner M1 (225) → third switch 224 → first antenna switch 221 → first antenna 231;

[0184] Processing circuit 210 →PA1 (2281) →duplexer 226 →combiner M1 (225) →third switch 224 →combiner M2 (221) →first antenna switch 221 →first antenna 231.

[0185] Exemplarily, when the wireless communication device 200 is in the first scenario, the processing circuit 210 may send the second signal (for the sake of convenience, it may be referred to as signal S21 later) to PA1 (2281). And send the third frequency band state control signal to the third switch 224, so that the third switch 224 turns on the data port p16 coupled to the combiner M2 (221) in the third switch 224 and the frequency band port f4 in the third switch 224 according to the third frequency band state control signal. And the eleventh antenna switching control signal may be sent to the first antenna switching switch 221, so that the first antenna switching switch 221 turns on the port p2 connected to the first antenna 231 in the first antenna switching switch 221 and the input port p1 connected to the combiner M2 (221) in the first antenna switching switch 221 according to the eleventh antenna switching control signal. Then PA1 (2281) may amplify the signal S21 to obtain the signal S22 and send the signal S22 to the duplexer 226. After the duplexer 226 filters the signal S22, a signal S23 is obtained, and then the signal S23 is sent to the combiner M1 (225), and the combiner M1 (225) sends the signal S23 to the third switch 224. After the third switch 224 performs frequency band selection on the signal S23, a signal S24 is obtained and sent to the combiner M2 (221). If the wireless communication device 200 is about to transmit the first signal to the first antenna 231, the processing circuit 210 may also transmit the first signal (which may be referred to as signal S11 for the convenience of subsequent description) to PA2 (2285), and transmit the sixth transceiver state control signal to the transceiver switch TR1 (227), so that the transceiver switch TR1 (227) adjusts the transceiver switch TR1 (227) to the transmitting state according to the sixth transceiver state control signal, that is, the port p17 of the transceiver switch TR1 (227) coupled to the second antenna switching switch 2231 and the port p18 of the transceiver switch TR1 (227) coupled to the filter LB3 (2293) are turned on. The seventh antenna switching control signal can be sent to the second antenna switching switch 2231, so that the second antenna switching switch 2231 turns on the port p9 coupled to the SRS switch 2232 and the port p4 coupled to the transceiver switch TR1 (227) in the second antenna switching switch 2231 according to the seventh antenna switching control signal.The sixth SRS state control signal can be sent to the SRS switch 2232, so that the SRS switch 2232 can conduct the port p5 coupled to the combiner M2 (221) and the port p10 coupled to the second antenna switch 2231 in the SRS switch 2232 according to the sixth SRS state control signal; and the tenth antenna switching control signal can be sent to the first antenna switching switch 221, so that the first antenna switching switch 221 can conduct the port p2 coupled to the first antenna 231 and the port p1 coupled to the combiner M2 (221) in the first antenna switching switch 221 according to the tenth antenna switching control signal. After receiving the first signal, PA2 (2285) can amplify the signal S11 to obtain the signal S12, and send the signal S12 to the filter LB3 (2293). The filter LB3 (2293) can filter the signal S12 to obtain the signal S13 and send the signal S13 to the transceiver switch TR1 (227). The transceiver switch TR1 (227) sends the signal S13 to the second antenna switching switch 2231. The second antenna switching switch 2231 can send the signal S13 to the SRS switch 2232, and the SRS switch 2232 can send the signal S13 to the combiner M2 (221). Then the combiner M2 (221) can receive the signals S13 and S24, and combine the signals S13 and S24 to obtain a combined signal; then the signal S24 is sent to the first antenna switching switch 221, and the first antenna switching switch 221 transmits the signal S24 after the frequency band conversion from the first antenna 231.

[0186] Exemplarily, when the wireless communication device 200 is in the second scene, the second signal can be transmitted from the first channel. The process of the wireless communication device 200 transmitting the second signal can be as follows: the processing circuit 210 can send the second signal (for the sake of convenience, it can be referred to as signal S21 later) to PA1 (2281). And send a fourth frequency band state control signal to the third switch 224, so that the third switch 224, according to the fourth frequency band state control signal, turns on the frequency band port f2 in the third switch 224 and the port p15 in the third switch 224 coupled to the first antenna switching switch 221. And the twelfth antenna switching switch control signal can be sent to the first antenna switching switch 221, so that the first antenna switching switch 221, according to the twelfth antenna switching switch control signal, turns on the port p2 in the first antenna switching switch 221 connected to the first antenna 231 and the input port p14 in the first antenna switching switch 221 connected to the third switch 224. Then, PA1 (2281) can amplify the signal S21 to obtain the signal S22 and send the signal S22 to the duplexer 226. After the duplexer 226 filters the signal S22, the signal S23 can be obtained, and then the signal S23 is sent to the combiner M1 (225), and the combiner M1 (225) sends the signal S23 to the third switch 224. After the third switch 224 selects the frequency band of the signal S23, the signal S24 is obtained and sent to the first antenna switching switch 221. The first antenna switching switch 221 transmits the signal S24 after the frequency band conversion from the first antenna 231.

[0187] Exemplarily, when the wireless communication device 200 is in the first communication scenario, the wireless communication device 200 can obtain the third signal through the first antenna 231 → first antenna switching switch 221 → combiner M2 (221) → third switch 224 → combiner M1 (225) → duplexer 226 → LNA1 (2282) → processing circuit 210.

[0188] Exemplarily, when the wireless communication device 200 is in the first communication scenario, the first antenna 231 of the wireless communication device 200 can receive the third signal (hereinafter referred to as S31 for the sake of convenience) transmitted by the base station, and then send the signal S31 to the first antenna switching switch 221. Since the port p1 coupled to the combiner M2 (221) in the first antenna switching switch 221 and the port p2 coupled to the first antenna 231 in the first antenna switching switch 221 are conductive when the wireless communication device 200 is in the first communication scenario, the combiner M2 (221) can receive the signal S31 through the first antenna switching switch 221. Then, the combiner M2 (221) can send the signal S31 to the third switch 224, and the third switch 224 selects the frequency band of the signal S31 to obtain the signal S32 and send the signal S32 to the combiner M1 (225). The combiner M1 (225) can send the signal S32 to the duplexer 226. After the duplexer 226 filters the signal S32, it obtains the signal S33 and sends it to the LNA1 (2282). The LNA1 (2282) amplifies the signal S33 to obtain the signal S34, and then sends the signal S34 to the processing circuit 210, and then the processing circuit 210 processes the third signal, such as RF demodulation, baseband demodulation, etc.

[0189] Exemplarily, when the wireless communication device 200 is in the second communication scenario, the wireless communication device 200 can obtain the fourth signal through the first antenna 231 → first antenna switching switch 221 → third switch 224 → combiner M1 (225) → duplexer 226 → LNA1 (2282) → processing circuit 210.

[0190] Exemplarily, when the wireless communication device 200 is in the second communication scenario, the first antenna 231 of the wireless communication device 200 can receive the fourth signal (hereinafter referred to as S41 for the sake of convenience) transmitted by the base station, and then the signal S41 can be sent to the first antenna switching switch 221. Since when the wireless communication device 200 is in the second communication scenario, the port p14 coupled to the third switch 224 in the first antenna switching switch 221 and the port p2 coupled to the first antenna 231 in the first antenna switching switch 221 are conductive, and the frequency band port f2 in the third switch 224 and the port p15 coupled to the first antenna switching switch 221 in the third switch 224 are conductive, the third switch 224 can receive the signal S41 through the first antenna switching switch 221. Then, the third switch 224 can select the frequency band of the signal S41, obtain the signal S42, and send the signal S42 to the combiner M1 (225). The combiner M1 (225) can send the signal S42 to the duplexer 226. After the duplexer 226 filters the signal S42, it obtains the signal S43 and sends it to the LNA1 (2282). The LNA1 (2282) amplifies the signal S43 to obtain the signal S44, and then sends the signal S44 to the processing circuit 210, and then the processing circuit 210 processes the third signal, such as RF demodulation, baseband demodulation, etc.

[0191] Exemplarily, the path for the wireless communication device 200 to receive the third signal or the fourth signal may also include: the second antenna 232 → the first antenna switching switch 221 → LB2 (2292) → LNA3 (2284) → processing circuit 210, to obtain the third signal or the fourth signal.

[0192] Exemplarily, the path for the wireless communication device 200 to receive other signals of the first network may include:

[0193] First antenna 231 → first antenna switch 221 → combiner M2 (221) → third switch 224 → combiner M1 (225) → LB1 (2291) → LNA2 (2283) → processing circuit 210 (or second antenna 232 → first antenna switch 221 → combiner M2 (221) → third switch 224 → combiner M1 (225) → LB1 (2291) → LNA2 (2283) → processing circuit 210);

[0194] The third antenna 233 → the second antenna switch 2231 → the transceiver switch TR1 (227) → the LB4 (2294) → the LNA4 (2286) → the processing circuit 210;

[0195] Fourth antenna 234 → SRS switch 2232 → second antenna switch 2231 → LB5 (2295) → LNA5 (2287) → processing circuit 210;

[0196] The fifth antenna 235 →transmitting / receiving switch TR2 ( 2233 ) →LB6 ( 2296 ) →LNA6 ( 2288 ) →processing circuit 210 .

[0197] It should be noted that when the wireless communication device is in the first communication scenario, if it is necessary to transmit the first signal and the second signal from the second antenna 232, then in addition to controlling the port p1 and the port p3 of the first switch 222 to be turned on, the states of the other switches are similar to the states of the other switches when the wireless communication device is in the first communication scenario and sends the first signal and the second signal from the first antenna 231, and will not be repeated here.

[0198] Exemplarily, when the wireless communication device is in the second communication scenario, if it is necessary to transmit a second signal from the second antenna 232, in addition to controlling port p14 and port p3 of the first switch 222 to be connected, the states of other switches are similar to the states of other switches when the wireless communication device is in the second communication scenario and sends the second signal from the first antenna 231, and will not be repeated here.
