[0002] In order to meet users' increasingly high experience requirements for electronic devices, many measures have been added to electronic devices to improve user experience performance. For example, multiple antennas are set in electronic devices, and when the channel quality of the currently used antenna is poor, it can switch to other antennas. However, electronic devices that support antenna selection / antenna switching still have the problem of poor communication performance. Summary of the invention

[0003] In view of this, the wireless communication device and equipment provided in the present application can enhance the radiation power of the transmitted signal without sacrificing the receiving performance, thereby improving the communication performance.

[0020] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the specific technical solution of the present application will be further described in detail below in conjunction with the drawings in the embodiments of the present application. The following embodiments are used to illustrate the present application, but are not used to limit the scope of the present application.

[0021] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art to which this application belongs. The terms used herein are only for the purpose of describing the embodiments of this application and are not intended to limit this application.

[0022] In the following description, reference is made to “some embodiments”, “this embodiment”, “embodiments of the present application” and examples, etc., which describe a subset of all possible embodiments, but it can be understood that “some embodiments” may be the same subset or different subsets of all possible embodiments and may be combined with each other without conflict.

[0023] The descriptions of “first, second, third” etc. that appear in the embodiments of the present application are only for illustration and distinction of the description objects. There is no distinction of order, nor do they indicate any special limitation on the number of devices in the embodiments of the present application, and cannot constitute any limitation on the embodiments of the present application.

[0024] The network architecture and business scenarios described in the embodiments of the present application are intended to more clearly illustrate the technical solutions of the embodiments of the present application, and do not constitute a limitation on the technical solutions provided by the embodiments of the present application. It is known to those skilled in the art that with the evolution of network architecture and the emergence of new business scenarios, the technical solutions provided by the embodiments of the present application are also applicable to similar technical problems.

[0025] The wireless communication device provided in the embodiment of the present application can be applicable to both terminals and base stations. These terminals and base stations can adopt a main set of transmitting antennas and a main set of receiving antennas that are separately set.

[0026] The wireless communication device provided in the embodiment of the present application can be applied to the fourth generation mobile communication system (the 4th generation mobile communication system, 4G), the fifth generation mobile communication technology (5th-Generation wireless communication technology, 5G) new radio (New Radio, NR) system or future communication system, and can also be used in various other wireless communication systems, such as: Narrow Band-Internet of Things (NB-IoT) system, Global System of Mobilecommunication (GSM), Enhanced Data rate for GSM Evolution (EDGE) system, Wideband Code Division Multiple Access (WCDMA) system, Code Division Multiple Access 2000 (CDMA2000) system, Time Division-Synchronization Code Division Multiple Access (TD-SCDMA) system, General Packet Radio Service (GPRS), Long Term Evolution (LTE) system, LTE Frequency Division Duplex (FDD-S) system. Duplex (FDD) system, LTE time division duplex (TDD) system, Universal Mobile Telecommunication System (UMTS) system, etc.

[0027] Related antenna solutions are all targeted at cellular chips. Currently, many chips and platforms support the switching of smart antennas by integrating switching logic and algorithms based on cellular chips. For example, Figure 1 As shown, it shows the structure of a wireless communication device, such as Figure 1As shown, the wireless communication device includes a modem 100, a radio frequency front-end module 200, a path switching module 300, an antenna ANT1, an antenna ANT2, ..., an antenna ANTM-1 and an antenna ANTM; wherein the modem 100 includes a baseband processor 130, a radio frequency transceiver 110 and a switching control module 120, and M is greater than or equal to 4, that is, the wireless communication device includes at least 4 antennas. Antenna ANT1 and antenna ANT2 are transceiver antennas, and antenna ANTM-1 and antenna ANTM are receiving antennas. Among them, the switching control module 120 can be a module in the baseband processor 130. For the transmitted signal, the module is used to determine the antenna with the best transmission performance from the multiple transceiver antennas connected to the path switching module 300, generate a first switching instruction based on this, and send the first switching instruction to the RF transceiver 110. The RF transceiver 110 controls the path switching module 300 to conduct the path between the antenna with the best transmission performance and the RF front-end module according to the first switching instruction; for the received signal, the switching control module 120 is also used to determine the antenna with the best receiving performance from the multiple receiving antennas and transceiver antennas connected to the path switching module 300, generate a second switching instruction based on this, and send the second switching instruction to the RF transceiver 110. The RF transceiver 110 controls the path switching module 300 to conduct the path between the antenna with the best receiving performance and the RF front-end module 200 according to the second switching instruction.

[0028] Specifically, the switching control module 120 may select an antenna with the best transmission performance (ie, the largest transmission power) from among the multiple connected transceiver antennas according to the transmission powers of the multiple transceiver antennas.

[0029] The switching control module 120 may select an antenna with the best receiving performance (ie, the largest received signal strength) from among the multiple connected transceiver antennas according to the strength of the received signals of the antennas.

[0030] Figure 1 The wireless communication device shown has the following problems from the application point of view: since the transmission channel also passes through the path switching module, the transmission capability of the product will also be reduced.

[0031] For example, Figure 2A As shown, the structure that does not support antenna selection, the antenna is directly connected to the RF front-end module without going through RF devices such as switches and combiners, and the structure that supports antenna selection, such as Figure 2BAs shown, the antenna is connected to the RF front-end module through RF devices such as switches and combiners. It can be seen that the structure that supports antenna selection / antenna switching is different from the structure that does not support antenna selection because it needs to introduce RF devices such as switches and combiners, which leads to the crossing and inner layer routing of the actual printed circuit board (PCB). In addition, the introduction of RF devices such as switches and combiners further increases the insertion loss of the link. It can be seen that if the transmitted signal passes through the path switching module (i.e., RF devices such as switches and combiners), the transmitted signal will be damaged, thereby affecting the communication performance. For the terminal, the performance of the transmitting antenna is particularly important.

[0032] Based on this, an embodiment of the present application provides a wireless communication device, Figure 3 A schematic diagram of the structure of a wireless communication device provided in an embodiment of the present application, such as Figure 3 As shown, the wireless communication device 3 includes at least one first antenna 31, at least two second antennas 32, a radio frequency front-end module 33 and a path switching module 34; wherein the at least one first antenna 31 is connected to the radio frequency front-end module 33, and the at least two second antennas 32 are connected to the radio frequency front-end module 33 through the path switching module 34; wherein,

[0033] The at least one first antenna 31 is at least used as a transmitting antenna, for transmitting the first transmitting signal output by the RF front-end module 33;

[0034] The at least two second antennas 32 are used as receiving antennas for receiving receiving signals;

[0036] It can be understood that the path switching module 34 is used to select the second antenna 32 , and therefore, the module 34 at least includes a switch module for conducting the path between the RF front-end module 33 and any one of the at least two second antennas 32 .

[0037] In an embodiment of the present application, the at least one first antenna 31 with a transmitting function is connected to the RF front-end module 33, rather than being connected to the RF front-end module 33 through a path switching module 34, so that the first transmit signal does not need to pass through the path switching module 34 (such as RF devices such as switch devices therein), but is transmitted through the first antenna 31, thereby avoiding introducing more insertion loss into the first transmit signal, thereby enhancing the radiation power of the first transmit signal and further improving the communication performance.

[0038] It can be understood that, for the transmission signal, the RF front-end module 33 is used to perform power amplification and other processing on the transmission signal output by the RF transceiver and then output it to the first antenna 31; for the reception signal, the RF front-end module 33 is also used to filter (such as through filter processing) and amplify (such as through low noise amplifier processing) the input reception signal. Exemplarily, in some embodiments, the RF front-end module 33 may include a transceiver unit directly connected to the transceiver antenna, and the transceiver unit may be a PAMID, which may be understood as a power amplifier module with a built-in low noise amplifier, which can support the transceiver processing of the RF signal. That is, the PAMID is a power amplifier module that integrates components such as a low noise amplifier, a power amplifier, and a filter in the same device, thereby improving the integration of the device and compressing the occupied space of the whole machine.

[0039] The RF front-end module 33 may also include a receiving unit connected to the receiving antenna through a path switching module 34. The receiving unit may be a DRX (diversity receive) device, a RF low noise amplifier front end module (LFEM) device, etc., which integrates components such as a low noise amplifier and a filter in the same device to improve the integration of the device and reduce the occupied space of the whole machine. In the embodiment of the present application, the specific types of the receiving unit and the transceiver unit are not limited.

[0041] The RF transceiver 41 is used to convert the first baseband signal output by the baseband processor into a corresponding second transmission signal and transmit it to the RF front-end module 33. Accordingly, the RF front-end module 33 is used to perform power amplification processing on the second transmission signal to obtain a first transmission signal;

[0042] The at least one first antenna 31 is at least used as a transmitting antenna, for transmitting the first transmitting signal output by the RF front-end module 33;

[0043] The at least two second antennas 32 are used as receiving antennas for receiving receiving signals;

[0044] The path switching module 34 is used to conduct the path between any one of the at least two second antennas 32 and the RF front-end module 33 to transmit the received signal to the RF front-end module 33, and the RF front-end module 33 is used to filter and / or amplify the received signal.

[0045] The RF transceiver 41 is further configured to convert the received signal after filtering and / or amplification by the RF front-end module 33 into a corresponding second baseband signal.

[0046] The present application further provides a wireless communication device, Figure 5 A schematic diagram of the structure of a wireless communication device provided in an embodiment of the present application, such as Figure 5 As shown, the wireless communication device 3 further includes a baseband processor 51, and the baseband processor 51 is connected to the RF transceiver 41; wherein,

[0047] The baseband processor 51 is used for converting the data to be transmitted into the first baseband signal and then outputting it to the RF transceiver 41;

[0048] The RF transceiver 41 is used to convert the first baseband signal output by the baseband processor into a corresponding second transmission signal and transmit it to the RF front-end module 33. Accordingly, the RF front-end module 33 is used to perform power amplification processing on the second transmission signal to obtain a first transmission signal;

[0049] The at least one first antenna 31 is at least used as a transmitting antenna, for transmitting the first transmitting signal output by the RF front-end module 33;

[0050] The at least two second antennas 32 are used as receiving antennas for receiving receiving signals;

[0052] The RF transceiver 41 is further configured to convert the received signal after filtering and / or amplification by the RF front-end module 33 into a corresponding second baseband signal.

[0053] The baseband processor 51 is further configured to decode the second baseband signal.

[0054] The following describes further optional implementations and related terms of each of the above modules / devices.

[0055] In the embodiment of the present application, the number of the first antennas 31 is not limited, and the device includes at least one first antenna 31 .

[0056] In one possible implementation, the at least one first antenna 31 is a first antenna, that is, the wireless communication device 3 includes a first antenna 31, and the first antenna 31 is an omnidirectional antenna; in this way, there is no dead angle in the radiation direction of the transmitted signal, which is beneficial to enhancing the communication performance.

[0057] In another possible implementation, the at least one first antenna 31 is at least two first antennas, that is, the wireless communication device 3 includes at least two first antennas 31, and the at least two first antennas 31 are omnidirectional antennas.

[0058] In another possible implementation, the at least one first antenna 31 is at least two first antennas, and the at least two first antennas 31 are directional antennas, and the radiation directions of the at least two first antennas 31 are complementary; in this way, there is no dead angle in the radiation direction of the transmitted signal, that is, the transmitted signal can be transmitted in all directions, which is beneficial to enhance communication performance. For example, the sum of the radiation directions of the at least two first antennas 31 is 360°.

[0059] In the embodiment where the at least two first antennas 31 are directional antennas, the radiation surfaces of the multiple first antennas 31 face different directions, and the radiation directions are complementary, so that the beam scanning range of each first antenna 31 can achieve omnidirectional coverage in the horizontal plane.

[0060] In the embodiment of the present application, there is no limitation on the type of the first antenna 31. The first antenna 31 can be used only as a transmitting antenna, or as both a transmitting antenna and a receiving antenna, that is, the first antenna 31 can be a transceiver antenna having both a receiving function and a transmitting function.

[0061] That is, in some embodiments, the first antenna 31 is used as a transceiver antenna, and the first antenna 31 is also used to receive a receive signal.

[0062] It can be understood that in the embodiment of the present application, the wireless communication device 3 includes at least two second antennas 32. In order to prevent the wireless communication device 3 from having a reception dead spot, that is, the problem of being unable to receive a received signal in a certain direction, in some embodiments, the at least two second antennas 32 are directional antennas, and the radiation directions of the at least two second antennas 32 are complementary. For example, the sum of the radiation directions of the at least two second antennas 32 is 360°.

[0063] In the embodiment where the at least two second antennas 32 are directional antennas, the radiation surfaces of the plurality of second antennas 32 face different directions and the radiation directions are complementary, so that the beam scanning range of each second antenna 32 can achieve omnidirectional coverage in the horizontal plane.

[0064] In some embodiments, the wireless communication device 3 also includes a mainboard (also called a single board), the RF front-end module 33 and the path switching module 34 are integrated on the mainboard, and the distance between the first antenna 31 and the mainboard is greater than the distance between the second antenna 32 and the mainboard; in this way, the transmission signal emitted by the first antenna is as unaffected by the mainboard as possible, thereby enhancing the transmission performance of the transmission signal and improving the communication performance.

[0065] In the embodiment of the present application, the number of the path switching modules 34 included in the wireless communication device 3 is not limited, and can be one or more. However, no matter whether there are one or more path switching modules 34, each path switching module 34 is connected to at least two second antennas 32.

[0066] In the embodiment of the present application, the multiple first antennas 31 included in the wireless communication device 3 can be antennas of the same model or antennas of different models. The multiple second antennas 32 included in the wireless communication device 3 can be antennas of the same model or antennas of different models.

[0067] In some embodiments, the first antenna 31 may be a 5G antenna, a 4G antenna, a Wi-Fi antenna, a Bluetooth antenna, etc., for correspondingly transmitting and receiving radio frequency signals of corresponding frequency bands.

[0068] In some embodiments, the second antenna 32 may be a 5G antenna, a 4G antenna, a Wi-Fi antenna, or a Bluetooth antenna, etc., for receiving radio frequency signals of corresponding frequency bands.

[0069] The following describes an exemplary application of the embodiments of the present application in a practical application scenario.

[0070] In the embodiments of the present application, Figure 6 The wireless communication device shown classifies the radio frequency channels into a transmit / receive (TRX) channel and a receive (RX) channel, wherein the TRX channel has no switching switch, thereby reducing the signal loss of the transmit channel. Only the RX channel is switched, and a better antenna switching architecture is achieved by arranging the field diagram of the RX antenna.

[0071] like Figure 6 The wireless communication device shown includes a baseband processor 51, an RF transceiver 41, a switching control module 61, an RF front-end module 33, a path switching module 34 and at least an antenna ANT1, an antenna ANTN, an antenna ANTM-1 and an antenna ANTM; wherein the two transceiver antennas, antenna ANT1 and antenna ANTN, are an example of the first antenna 31, and the two antennas, antenna ANTM-1 and antenna ANTM, are an example of the second antenna 32.

[0072] like Figure 6 As shown, the baseband processor 51 is connected to the RF transceiver 41, the antenna ANTM-1 and the antenna ANTM are connected to the RF front-end module 33 through the path switching module 34, and the antenna ANT1 and the antenna ANTN are connected to the RF front-end module 33; wherein,

[0073] As for the control logic of the path switching module 34, in one possible implementation, the switching control module 61 may be a part of the baseband processor 51. The switching control module 61 is used to compare the performances of multiple antennas connected to the path switching module 34, and select the antenna with the best receiving performance as the receiving antenna for receiving signals. Based on this, a switching instruction is generated and sent to the RF transceiver 41. The RF transceiver 41 controls the path switching module 34 to turn on the path between the RF front-end module 33 and the antenna with the best receiving performance according to the switching instruction.

[0074] Specifically, in some embodiments, the switching control module 61 may compare the received signal strengths of the antennas connected to the path switching module 34 and use the antenna with the largest received signal strength as the antenna with the best receiving performance.

[0075] Of course, in another possible implementation, after determining the antenna with the best receiving performance, the switching control module 61 may also directly control the path switching module 34 to conduct the path between the RF front-end module 33 and the antenna with the best receiving performance.

[0076] In some embodiments, the antennas of the RX switching (i.e., the second antenna 32) have a complementary relationship in the spatial field diagram. Figure 7 As shown, the wireless communication device includes 2 TRX antennas (i.e., an example of the first antenna 31) and 4 RX antennas (i.e., an example of the second antenna 32), wherein antenna ANT0 and antenna ANT1 are TRX antennas, which are connected to the RF front-end module 33, antenna ANT2-1 and antenna ANT2-2 are connected to the RF front-end module 33 through a switch 71 (i.e., an example of a path switching module 34), and antenna ANT3-1 and antenna ANT3-2 are connected to the RF front-end module 33 through a switch 72 (i.e., an example of a path switching module 34).

[0077] In some embodiments, the typical applications and deployments of these six antennas are as follows: Figure 8 As shown, this architecture can produce the following advantages:

[0078] (1) RX2 / RX3 supports antenna switching, that is, switch 71 and switch 72 support antenna switching, which can obtain advantages in the receiving link. At the same time, since antenna ANT0 and antenna ANT1 are transceiver antennas, the wireless communication device can reduce two antennas compared with the conventional antenna architecture. Antenna ANT0 and ANT1 are farthest from the single board in spatial distance, thereby achieving optimal isolation, and there is no complementary relationship in directionality.

[0079] (2) Since there is no switch on the channel of the transmitting antenna, compared with the conventional antenna selection architecture, its radiation capability is stronger, that is, the total radiated power (TRP) is higher, so better transmission performance can be obtained. In this way, the cost is more advantageous without sacrificing the transmission performance of the product.

[0080] (3) Since there are fewer antennas and switches, the cost is lower than that of conventional antenna selection architectures.

[0081] In some embodiments, the performance requirements of the antenna are as follows: antenna ANT0 and antenna ANT1 are omnidirectional antennas, and antenna ANT2-1, antenna ANT2-2, antenna ANT3-1, and antenna ANT3-2 are directional high-gain antennas. That is, the transceiver antennas are omnidirectional antennas, and the receiving antennas are high-gain antennas; in this way, the receiving performance can be enhanced without sacrificing the transmitting performance.
