[0002] In wireless communication systems, a traditional antenna panel can be divided into three zones. At one moment, the antenna subarray in one of the three zones is transmitting radio frequency signals. At another moment, the antenna subarray in another zone is receiving radio frequency signals. In this scenario, the traditional antenna panel suffers from poor radio frequency coverage. Summary of the Invention

[0003] In order to solve the above technical problems, the present application provides a communication device and a signal processing method, which can improve the uplink coverage or downlink coverage of the antenna surface.

[0004] To achieve the above objectives, this application adopts the following technical solutions:

[0005] According to a first aspect, a communication device is provided. The communication device includes a first radio frequency circuit and an antenna panel, wherein the antenna panel includes a first region, a second region, and a third region. The first radio frequency circuit includes a first transmitting circuit and a first receiving circuit. The first transmitting circuit is connected to a first antenna subarray. The first antenna subarray is located in the first region, which is located between the second and third regions. The first receiving circuit is connected to the first antenna subarray.

[0006] That is, an antenna sub-array, ie, the first antenna sub-array, is provided in the first area of ​​the antenna panel.

[0007] On the one hand, the first antenna subarray is connected to the first transmitting circuit, laying the foundation for the first antenna subarray to send radio frequency signals in the downlink time unit of the non-sub-band full-duplex SBFD time unit, thereby increasing the number of antenna subarrays that realize the transmitting function in the antenna panel, helping to improve the downlink coverage of the antenna panel and also improving the utilization rate of the antenna panel.

[0008] On the other hand, the first antenna subarray is connected to the first receiving circuit, laying the foundation for the first antenna subarray to receive radio frequency signals in the uplink time unit of the non-SBFD time unit, thereby increasing the number of antenna subarrays that realize the receiving function in the antenna panel, helping to improve the uplink coverage of the antenna panel and also improving the utilization rate of the antenna panel.

[0009] In a possible design, the first area is located below the second area, and the first area is located above the third area.

[0010] In one possible design, the first transmitting circuit is further connected to a second antenna subarray and a third antenna subarray. The first receiving circuit is further connected to the second antenna subarray and the third antenna subarray. The second antenna subarray is located in the second area, and the third antenna subarray is located in the third area.

[0011] That is, antenna subarrays in different areas are connected to the same transmitting circuit. When the first transmitting circuit performs processing, the transmitting function can be implemented by antenna subarrays in different areas, for example, the transmitting function can be implemented by the third antenna subarray, or the transmitting function can be implemented by the third antenna subarray and the first antenna subarray, or the transmitting function can be implemented by the first antenna subarray, the second antenna subarray, and the third antenna subarray.

[0012] Similarly, antenna subarrays in different regions are connected to the same receiving circuit. When the first receiving circuit performs processing, the receiving function can be implemented by antenna subarrays in different regions, for example, the receiving function can be implemented by the second antenna subarray, or the receiving function can be implemented by the second antenna subarray and the first antenna subarray, or the receiving function can be implemented by the first antenna subarray, the second antenna subarray, and the third antenna subarray.

[0013] In one possible design, the first antenna subarray is configured to neither send nor receive the first radio frequency signal in a first time unit, wherein the first time unit is a sub-band full-duplex (SBFD) time unit.

[0014] The second antenna subarray is configured to receive a first signal in the first time unit. The first receiving circuit is configured to process the first signal in the first time unit to obtain a second signal.

[0015] The first transmitting circuit is configured to process the third signal in the first time unit to obtain a fourth signal. The third antenna subarray is configured to send the fourth signal in the first time unit.

[0016] Thus, during the first time unit, the communication device receives signals via the first receiving circuit and the second antenna subarray, and transmits signals via the first transmitting circuit and the third antenna subarray, thereby achieving duplex communication. Furthermore, the first antenna subarray neither transmits nor receives the first RF signal, thereby achieving isolation and improving communication performance.

[0017] In one possible design, the first transmitting circuit is configured to process the fifth signal in a second time unit to obtain a sixth signal, wherein the second time unit is a downlink time unit in a non-SBFD time unit.

[0018] The first antenna subarray is configured to send the sixth signal in the second time unit. The third antenna subarray is configured to send the sixth signal in the second time unit.

[0019] That is, during the second time unit, the first antenna subarray transmits the sixth signal only when the third antenna subarray is transmitting a signal. This increases the number of antenna subarrays used for signal transmission, and accordingly, increases the antenna panel area used for signal transmission, thereby increasing signal gain and improving downlink coverage.

[0020] In one possible design, the second antenna subarray is used to send the sixth signal in the second time unit.

[0021] That is, in the second time unit, the second antenna subarray sends the sixth signal only when both the first antenna subarray and the third antenna subarray send signals, thereby achieving the effect of further improving downlink coverage.

[0022] In one possible design, the second antenna subarray is configured to not send the sixth signal and not receive the second radio frequency signal in the second time unit.

[0023] It can be understood that, during the second time unit, the second antenna subarray is not working. In other words, during the second time unit, the communication device sends the sixth signal through the first antenna subarray and the third antenna subarray.

[0025] The first receiving circuit is configured to process the seventh signal and the eighth signal in the third time unit.

[0026] That is, during the third time unit, the first antenna subarray performs signal reception only when the second antenna subarray is receiving signals. This increases the number of antenna subarrays used for signal reception and, accordingly, the antenna panel area used for signal reception, thereby improving uplink coverage.

[0027] In one possible design, the third antenna subarray is configured to receive a ninth signal in the third time unit. The first receiving circuit is further configured to process the ninth signal in the third time unit.

[0028] That is, in the third time unit, the third antenna subarray receives signals only when both the first antenna subarray and the second antenna subarray receive signals, thereby achieving an effect of further improving uplink coverage.

[0029] In one possible design, the third antenna subarray is configured to not send a third RF signal and not receive a ninth signal in the third time unit.

[0030] It can be understood that during the third time unit, the third antenna subarray is not working. In other words, during the third time unit, the communication device receives signals through the first antenna subarray and the second antenna subarray.

[0034] The fourth analog circuit is connected to the first antenna subarray, the fifth analog circuit is connected to the second antenna subarray, and the sixth analog circuit is connected to the third antenna subarray.

[0035] That is, in the first transmitting circuit, antenna subarrays in different regions are connected to their own analog circuits, and the analog circuits connected to antenna subarrays in different regions are connected to the same digital circuit. When the first digital circuit performs processing, the transmitting function can be implemented by different analog circuits and the antenna subarrays corresponding to these analog circuits. For example, the transmitting function can be implemented by the third analog circuit and the third antenna subarray. For another example, the transmitting function can be implemented by the third analog circuit and the third antenna subarray, as well as the first analog circuit and the first antenna subarray.

[0039] The first digital circuit is configured to perform digital-to-analog conversion on the thirteenth signal during the first time unit to obtain a fourteenth signal. The third analog circuit is configured to amplify the fourteenth signal during the first time unit to obtain a fifteenth signal. The third antenna subarray is configured to transmit the fifteenth signal during the first time unit.

[0040] That is, during the first time unit, the communication device receives signals via the second digital circuit, the fifth analog circuit, and the second antenna subarray, and transmits signals via the first digital circuit, the third analog circuit, and the third antenna subarray, thereby achieving duplex communication. Furthermore, the first antenna subarray does not transmit the fourth radio frequency signal and does not receive the fifth radio frequency signal, thereby achieving an isolation effect and improving communication performance.

[0043] The third analog circuit is configured to amplify the seventeenth signal in the second time unit to obtain a nineteenth signal. The third antenna subarray is configured to transmit the nineteenth signal in the second time unit.

[0044] That is, during the second time unit, the first antenna subarray transmits signals only when the third antenna subarray transmits signals. This increases the number of antenna subarrays used for signal transmission, and accordingly, the antenna panel area used for signal transmission increases, increasing signal gain and improving downlink coverage.

[0045] In one possible design, the second analog circuit is configured to amplify the seventeenth signal in the second time unit to obtain a twentieth signal, and the second antenna subarray is configured to transmit the twentieth signal in the second time unit.

[0046] That is, in the second time unit, the second antenna subarray sends the twentieth signal only when both the first antenna subarray and the third antenna subarray send signals, thereby further improving downlink coverage.

[0047] In one possible design, the second analog circuit is configured to not perform amplification processing during the second time unit, so that the second antenna subarray does not transmit the twentieth signal during the second time unit. Furthermore, the fifth analog circuit is configured to not perform amplification processing during the second time unit, so that the second antenna subarray does not receive the sixth RF signal during the second time unit.

[0177] In the embodiments of the present application, “of”, “corresponding”, “relevant” and “corresponding” may sometimes be used interchangeably. It should be noted that when the distinction between them is not emphasized, the meanings they intend to express are consistent.

[0178] 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 in the embodiments of the present application. A person skilled in the art will appreciate that, with the evolution of the network architecture and the emergence of new business scenarios, the technical solutions provided in the embodiments of the present application are equally applicable to similar technical problems.

[0179] Figure 1 FIG. 1 is a schematic diagram of the architecture of the communication system 1000 used in the embodiment of the present application. Figure 1 As shown, the communication system 1000 includes at least one network device (such as Figure 1 110a and 110b) and at least one terminal device (such as Figure 1 120a-120j in FIG. 120b). The terminal device may communicate with the network device wirelessly. Alternatively, different network devices may communicate with each other. Alternatively, different terminal devices may communicate with each other.

[0180] It should be pointed out that Figure 1 It is only a schematic diagram. Although not shown, the communication system 1000 may also include other network devices, such as the communication system 1000 may also include one or more core network (CN) devices, wireless relay devices and wireless backhaul devices, which are not specifically limited here.

[0181] The network device can be connected to the core network device via wireless or wired communication.

[0182] Optionally, the network device is a network-side device with wireless transceiver functions. The network device may be a device in a radio access network (RAN) that provides wireless communication functions for terminal devices, referred to as a RAN device. The RAN may be an access network in the 3rd Generation Partnership Project (3GPP), for example, 4G, 5G, or future-oriented 6G networks. The RAN may also be an open access network (open RAN, O-RAN or ORAN), a cloud radio access network (CRAN), or a communication network of two or more of the above networks. RAN equipment can be a base station, an evolved NodeB (eNodeB), a transmission reception point (TRP), a next-generation nodeB (gNB) in a fifth-generation (5G) mobile communication system, a next-generation base station in a sixth-generation (6G) mobile communication system, a base station in a future mobile communication system, a wireless fidelity (WiFi) system, a long-range radio (LoRa) system, or an access node in a connected vehicle system. RAN equipment can also be a module or unit that performs some of the functions of a base station, such as a centralized unit (CU), a distributed unit (DU), or a radio unit (RU). The CU implements the base station's radio resource control protocol and packet data convergence protocol (PDCP), as well as the service data adaptation protocol (SDAP). The DU implements the base station's radio link control layer and medium access control (MAC) layer, as well as some or all of the physical layer. For detailed descriptions of each of these protocol layers, refer to the relevant technical specifications of the 3rd Generation Partnership Project (3GPP). The CU and DU can be separate or included in the same network element, such as the baseband unit (BBU).The RU may be included in a radio frequency device or a radio frequency unit, for example, in a remote radio unit (RRU), an active antenna unit (AAU) or a remote radio head (RRH). In different systems, CU, DU or RU may also have different names, but those skilled in the art can understand their meanings. For example, in an ORAN system, CU may also be called O-CU (open CU), DU may also be called O-DU, and RU may also be called O-RU. Any of the CU (or CU-CP, CU-UP), DU and RU in this application may be implemented by a software module, a hardware module, or a combination of a software module and a hardware module. The wireless access network device may be a macro base station (such as a base station). Figure 1 110a), or a micro base station or an indoor station (such as Figure 1 110b) in the figure, or a relay node or a donor node. The embodiments of this application do not limit the specific technology and device form used by the wireless access network device. For ease of description, network device is used as an abbreviation for wireless access network device, and base station is used as an example of wireless access network device.

[0183] Optionally, the terminal device accesses the core network via a network device. The terminal device includes a device that provides voice and / or data connectivity to the user. Specifically, it includes a device that provides voice to the user, a device that provides data connectivity to the user, or a device that provides both voice and data connectivity to the user. For example, it may include a handheld device with wireless connectivity or a processing device connected to a wireless modem. The terminal device can communicate with the core network via the radio access network, exchange voice or data with the RAN, or exchange voice and data with the RAN. The terminal device may include user equipment (UE), wireless terminal device, mobile terminal device, D2D terminal device, V2X terminal device, machine-to-machine / machine-type communications (M2M / MTC) terminal device, Internet of Things (IoT) terminal device, subscriber unit (subscriber runit), subscriber station, mobile station, remote station, access point (AP), remote terminal, access terminal, user terminal, user agent, or user device, etc. For example, it may include a mobile phone (or so-called "cellular" phone), a computer with a mobile terminal device, a portable, pocket-sized, handheld, or computer-built-in mobile device, etc. Examples include personal communication service (PCS) phones, cordless phones, session initiation protocol (SIP) phones, wireless local loop (WLL) stations, and personal digital assistants (PDAs). Also included are limited devices, such as those with low power consumption, limited storage capacity, or limited computing power. Examples include information sensing devices such as barcode scanners, radio frequency identification (RFID), sensors, global positioning systems (GPS), and laser scanners.

[0184] The various terminal devices introduced above, if located on a vehicle (eg, placed in or installed in a vehicle), can be considered as vehicle-mounted terminal devices, which are also called on-board units (OBUs).

[0185] In the embodiment of the present application, the terminal device may further include a relay. Alternatively, it can be understood that anything that can communicate data with a base station can be considered a terminal device.

[0186] In the embodiments of the present application, the device for implementing the functions of the terminal device can be the terminal device, or it can be a device that can support the terminal device to implement the functions, such as a chip system, which can be installed in the terminal device. In the embodiments of the present application, the chip system can be composed of chips, or it can include chips and other discrete devices. In the technical solutions provided in the embodiments of the present application, the device for implementing the functions of the terminal is a terminal device as an example for description.

[0187] It should be understood that network devices and terminal devices can be fixed or mobile. Network devices and terminal devices can be deployed on land, including indoors or outdoors, handheld or vehicle-mounted; they can also be deployed on water; and they can also be deployed in the air on aircraft, balloons, and artificial satellites. The embodiments of this application do not limit the application scenarios of network devices and terminal devices.

[0188] The roles of network devices and terminal devices can be relative. For example, Figure 1 The helicopter or drone 120i in the figure can be configured as a mobile base station. For the terminal devices 120j that access the wireless access network through 120i, the terminal device 120i is a network device; but for the network device 110a, 120i is a terminal device, that is, the communication between 110a and 120i is carried out through the wireless air interface protocol. Of course, the communication between 110a and 120i can also be carried out through the interface protocol between base stations. In this case, relative to 110a, 120i is also a network device. Therefore, network devices and terminal devices can be collectively referred to as communication devices. Figure 1 110a and 110b in the figure can be called communication devices with network device functions. Figure 1 120a-120j in the figure can be referred to as a communication device with terminal device functions. In addition, the communication device can also be at least one of the following: a module, unit, circuit, antenna, or chip of a device, such as a CU or DU. The circuit can include a radio frequency circuit. Furthermore, the circuit can further include other circuits. The communication device can also be a device, such as a terminal device (also referred to as user equipment) or a network device (such as a base station).

[0189] Network devices and terminal devices, network devices and network devices, and terminal devices and terminal devices can communicate through authorized spectrum, unauthorized spectrum, or both. They can communicate through spectrum below 6 gigahertz (GHz), spectrum above 6 GHz, or spectrum below 6 GHz and spectrum above 6 GHz. The embodiments of the present application do not limit the spectrum resources used for wireless communications.

[0190] In the embodiments of the present application, the functions of the network device may also be performed by a module (such as a chip) in the network device, or by a control subsystem that includes the network device functions. The control subsystem that includes the network device functions here may be a control center in the above-mentioned application scenarios such as smart grid, industrial control, smart transportation, and smart city. The functions of the terminal device may also be performed by a module (such as a chip or a modem) in the terminal device, or by a device that includes the terminal device functions.

[0191] In an embodiment of the present application, a network device sends a downlink signal or downlink information to a terminal device, and the downlink information is carried on a downlink channel; the terminal device sends an uplink signal or uplink information to the network device, and the uplink information is carried on an uplink channel. In order to communicate with the network device, the terminal device needs to establish a wireless connection with the cell controlled by the network device. The cell with which the terminal device has established a wireless connection is called the serving cell of the terminal device. When the terminal device communicates with the serving cell, it will also be interfered with by signals from neighboring cells.

[0192] It should be noted that the solutions in the embodiments of the present application can also be applied to other communication systems, and the corresponding names can also be replaced by the names of corresponding functions in other communication systems.

[0193] To facilitate understanding of the embodiments of the present application, the following briefly describes the terms used in the embodiments of the present application. It should be understood that these descriptions are only for facilitating understanding of the embodiments of the present application and should not constitute any limitation on the present application.

[0194] 1. Wireless frame

[0195] In wireless communication systems, data is transmitted in frames. A radio frame is the period during which data is sent. A radio frame typically takes up a very short time, for example, 10ms.

[0196] In addition, a wireless frame may also be referred to as a frame. In this application, a frame is used as an example for introduction.

[0197] In some embodiments, Figure 2A frame structure is shown. Figure 2 As shown in FIG, the time-frequency resources used for uplink transmission are such as the box where 'U' is located. The time-frequency resources used for downlink transmission are such as the box where 'D' is located. Figure 2 In the time domain, taking a frame as an example, a single moment can include only downlink time units, such as the dotted box containing "Downlink." A single moment can also include only uplink time units, such as the dotted box containing "Uplink." A single moment can also include both uplink and downlink time units, such as the dotted box containing "Sub-band Duplex."

[0198] In other embodiments, Figure 3 Another frame structure is shown. Figure 3 As shown, the time-frequency resources used for uplink transmission are such as the box where 'U' is located. The time-frequency resources used for downlink transmission are such as the box where 'D' is located. The time-frequency resources used for uplink and downlink transmission are such as the box where 'D+U' is located. The time-frequency resources used for uplink and downlink transmission can be reverted to the time-frequency resources used for uplink transmission. Alternatively, the time-frequency resources used for uplink and downlink transmission can be reverted to the time-frequency resources used for downlink transmission. Accordingly, in Figure 3 Taking a frame as an example, in the time domain, the same moment may include only downlink time units, only uplink time units, or both uplink time units and downlink time units.

[0199] 2. Subband full duplex (SBFD) time unit

[0200] In the present application, the frequency resources on the SBFD time unit include uplink frequency resources and downlink frequency resources, wherein the uplink frequency resources are used for uplink transmission and the downlink frequency resources are used for downlink transmission.

[0201] For example, Figure 4 A typical SBFD time-frequency division scheme is shown in Figure 4 In the figure, the horizontal axis represents time and the vertical axis represents frequency. The two rectangles filled with left slashes represent a group of time-frequency resources for downlink transmission, and the rectangle filled with vertical bars represents a group of time-frequency resources for uplink transmission. The time domain resources occupied by these three time-frequency resources are called SBFD time units.

[0202] 3. Non-SBFD time unit

[0203] In the present application, the frequency resource corresponding to each of all symbols included in the non-SBFD time unit is used only for downlink transmission or only for uplink transmission. As an example, all symbols in the non-SBFD time unit are downlink symbols, or all symbols in the non-full-duplex time unit are uplink symbols, or some symbols in the non-full-duplex time unit are downlink symbols and some are uplink symbols, or some symbols in the non-full-duplex time unit are downlink symbols, some are uplink symbols, and some are flexible symbols, or some symbols in the non-full-duplex time unit are downlink symbols and some are flexible symbols, or some symbols in the non-full-duplex time unit are uplink symbols and some are flexible symbols.

[0204] For example, Figure 4 The rectangular blocks filled with middle grid lines represent a set of time-frequency resources used for uplink transmission. The time slots occupied by them in the time domain are called uplink time units. The transmission direction of all frequency resources in these time units is uplink. These time units can be called non-SBFD time slots.

[0205] 4. Antenna panel

[0206] In this application, an antenna panel includes multiple antennas. The antenna panel can also be referred to as the antenna surface. In this application, the antenna panel is used as an example for introduction.

[0207] The antenna panel can be divided into three areas according to the traditional method, namely the first area, the second area and the third area. Figure 5 For example, the 'upper antenna' represents the antenna subarray in the second area, used to transmit the first radio frequency signal. The 'lower antenna' represents the antenna subarray in the third area, used to receive the second radio frequency signal. The 'isolation device' is located in the first area and is used for isolation.

[0208] For example, at a first moment, such as an SBFD time unit, the antenna subarray in the second area is used to transmit a first RF signal, and the antenna subarray in the third area is used to receive a second RF signal. An isolation device is provided in the first area to achieve transmission and reception isolation. The isolation device in the first area can be a blank antenna panel. The first area is located between the second and third areas.

[0209] For example, at the second moment, such as the downlink time unit of the non-SBFD time unit, the antenna subarray in the second area is used to send the first RF signal, and the first area is set as an isolation device and has no sending function, resulting in low downlink coverage of the antenna panel.

[0210] For example, at the third moment, such as the uplink time unit of the non-SBFD time unit, the antenna subarray in the third area is used to receive the second RF signal, and the first area is set as an isolation device and has no receiving function, resulting in low uplink coverage of the antenna panel.

[0211] In summary, under the traditional area division method of the antenna panel, only the antenna subarrays in some areas of the antenna panel have the function of sending or receiving RF signals in the non-SBFD time unit, and the coverage of the antenna panel is low.

[0212] In view of this, the embodiment of the present application provides a communication device and a signal processing method. Figure 1 A portion of the network device shown. The signal processing method can be applied to Figure 1 The network equipment shown helps to improve the downlink coverage or uplink coverage of the antenna panel.

[0213] Next, seven embodiments (embodiment 1 to embodiment 7) are described in detail.

[0214] Example 1

[0215] An embodiment of the present application provides a communications device. The communications device includes: a first radio frequency circuit and an antenna panel, the antenna panel including a first area, a second area, and a third area. The first radio frequency circuit includes a first transmitting circuit and a first receiving circuit. The first transmitting circuit is connected to a first antenna subarray. The first receiving circuit is connected to the first antenna subarray. The first antenna subarray is located in the first area, which is located between the second and third areas.

[0216] by Figure 6a For example, the antenna panel is shown in the dashed box. The first area is shown in the solid box where the "mid-sky plane" is located, the second area is shown in the solid box where the "upper sky plane" is located, and the third area is shown in the solid box where the "lower sky plane" is located. In other words, the first area is located below the second area, and the first area is located above the third area.

[0217] It should be understood that in this application, Figure 6a The positional relationship between the three regions (i.e., the first region, the second region, and the third region) is shown as an example. Of course, the antenna panel can also be divided into regions in other ways. For example, conversely, the first region is located below the third region, and the first region is located above the second region. Alternatively, the antenna panel can be divided into regions along other directions, which is not limited in the embodiments of the present application.

[0218] by Figure 6bFor example, the antenna subarray located in the first area can be denoted as the first antenna subarray. The first antenna subarray can be antenna subarray 5, antenna subarray 6, antenna subarray 7, or antenna subarray 8. The antenna subarray located in the second area can be denoted as the second antenna subarray. The second antenna subarray can be antenna subarray 1, antenna subarray 2, antenna subarray 3, or antenna subarray 4. The antenna subarray located in the third area can be denoted as the third antenna subarray. The third antenna subarray can be antenna subarray 9, antenna subarray 10, antenna subarray 11, or antenna subarray 12.

[0219] It should be understood that in this application, an antenna subarray may include one or more antennas. The number of antennas in an antenna subarray is related to the driving mode. For example, when the driving mode in the first direction is '1 drive X' and the driving mode in the second direction is '1 drive 1', an antenna subarray includes X antennas, where X is a positive integer. The first direction can be understood as a direction in the plane where the antenna panel is located, such as Figure 6b The second direction can be understood as another direction in the plane where the antenna panel is located, such as Figure 6b shown.

[0220] Furthermore, the number of antennas in different antenna subarrays can be the same or different. For example, the number of antennas in the first antenna subarray is different from the number of antennas in the second antenna subarray. The number of antennas in the first antenna subarray is different from the number of antennas in the third antenna subarray. The number of antennas in the second antenna subarray is different from the number of antennas in the third antenna subarray. The number of antennas in the first, second, and third antenna subarrays can be different. In this way, within the first time unit, the number of antennas in the first antenna subarray can be configured based on usage requirements, achieving a compromise between uplink and downlink capacity and coverage.

[0221] by Figure 7 For example, the first transmitting circuit is connected to the first antenna subarray via a circulator. The first receiving circuit is connected to the first antenna subarray via a circulator.

[0222] That is to say, in the communication device of the present application, an antenna subarray, namely the first antenna subarray, is provided in the first area of ​​the antenna panel. Moreover, on the one hand, the first antenna subarray is connected to the first transmitting circuit, which lays the foundation for the first antenna subarray to transmit radio frequency signals in the downlink time unit of the non-SBFD time unit, thereby increasing the number of antenna subarrays with transmitting functions in the antenna panel, helping to improve the downlink coverage of the antenna panel, and also improving the utilization rate of the antenna panel. On the other hand, the first antenna subarray is connected to the first receiving circuit, which lays the foundation for the first antenna subarray to receive radio frequency signals in the uplink time unit of the non-SBFD time unit, thereby increasing the number of antenna subarrays with receiving functions in the antenna panel, helping to improve the uplink coverage of the antenna panel, and also improving the utilization rate of the antenna panel.

[0223] It should be noted that different circuit structures may be used based on the first embodiment. Next, an introduction is given through three embodiments (ie, the following second to fourth embodiments).

[0224] Example 2

[0225] The embodiment of the present application provides a communication device. The communication device of the second embodiment is referred to as a first communication device.

[0226] The first communication device includes a first radio frequency circuit and an antenna panel. The antenna panel includes a first area, a second area and a third area. Figure 6b shown.

[0227] The first radio frequency circuit includes a first transmitting circuit and a first receiving circuit. Figure 8 shown.

[0228] like Figure 8 As shown, the first transmitting circuit is connected to the first antenna sub-array, the second antenna sub-array and the third antenna sub-array. The first antenna sub-array, the second antenna sub-array and the third antenna sub-array can be referred to the introduction of the first embodiment and will not be described in detail.

[0229] like Figure 8 As shown, the first receiving circuit is connected to the first antenna sub-array, the second antenna sub-array and the third antenna sub-array.

[0230] That is, antenna subarrays in different regions are connected to the same transmitting circuit. When the first transmitting circuit performs processing, the transmitting function can be implemented by antenna subarrays in different regions, for example, the transmitting function can be implemented by the third antenna subarray, or the transmitting function can be implemented by the third antenna subarray and the first antenna subarray, or the transmitting function can be implemented by the first antenna subarray, the second antenna subarray, and the third antenna subarray.

[0231] Similarly, antenna subarrays in different regions are connected to the same receiving circuit. When the first receiving circuit performs processing, the receiving function can be implemented by antenna subarrays in different regions, for example, by the second antenna subarray, or by the second antenna subarray and the first antenna subarray, or by the first antenna subarray, the second antenna subarray, and the third antenna subarray.

[0232] In addition, compared with the circuit structure in the related art, the number of radio frequency channels of the second communication device does not change, and does not affect the total transmission power configuration.

[0233] In some embodiments, the first communication device further comprises a first switch. Figure 8As shown, a first end of the first switch is connected to the first antenna subarray. A second end of the first switch is connected to the second antenna subarray. A third end of the first switch is connected to the third antenna subarray. A fourth end of the first switch is connected to the output of the first transmitting circuit and the input of the first receiving circuit.

[0234] by Figure 8 For example, the fourth end of the first switch is connected to the output end of the first transmitting circuit through the circulator Y, and the fourth end of the first switch is connected to the input end of the first receiving circuit through the circulator Y, the switch X and the second switch.

[0235] In this application, the first switch can be understood as a RF channel front-end switching switch.

[0236] In this way, the working states of the first antenna subarray, the second antenna subarray and the third antenna subarray can be controlled by the first switch, such as controlling at least one antenna subarray to implement the function of transmitting and receiving radio frequency signals.

[0237] In some embodiments, the first communication device further includes a second switch and a third switch.

[0238] like Figure 8 As shown, the third end of the second switch is connected to the input end of the first receiving circuit. The first end of the second switch is connected to the fourth end of the first switch. For example, the first end of the second switch is connected to the fourth end of the first switch through the switch X and the circulator.

[0239] like Figure 8 As shown, the third end of the third switch is connected to the second antenna sub-array, the first end of the third switch is connected to the second end of the first switch, and the second end of the third switch is connected to the second end of the second switch.

[0240] In this way, the working state of the second antenna sub-array can be controlled by the second switch and the third switch, such as controlling the second antenna sub-array to realize the receiving function of the radio frequency signal.

[0241] Next, the working status of each antenna subarray in the first communication device at different time units is introduced:

[0242] Case 1: Working status of each antenna subarray in the first communication device in the first time unit:

[0243] In case 1, the first time unit belongs to the SBFD time unit.

[0244] On the one hand, the first antenna subarray is configured not to send or receive the first radio frequency signal in the first time unit. This means that the first antenna subarray is inoperative in the first time unit, thereby achieving an isolation effect.

[0245] In this application, the radio frequency signal sent by the first antenna subarray in the first time unit belongs to the first radio frequency signal and can be recorded as TX 1-1-1 Among them, 'TX 1-1-1 It can be understood as: the radio frequency signal sent by the first antenna subarray of the first communication device in the first time unit.

[0246] In this application, the radio frequency signal received by the first antenna subarray in the first time unit belongs to the first radio frequency signal and can be recorded as RX 1-1-1 Among them, 'RX 1-1-1 ' can be understood as: the radio frequency signal received by the first antenna subarray of the first communication device in the first time unit.

[0247] That is, the first antenna subarray does not send the radio frequency signal TX in the first time unit. 1-1-1 , nor does it receive RF signals RX 1-1-1 .

[0248] In another aspect, the second antenna sub-array is used to receive the first signal in the first time unit. Accordingly, the first receiving circuit is used to process the first signal in the first time unit to obtain the second signal, thereby realizing the receiving function.

[0249] In this application, the radio frequency signal received by the second antenna sub-array in the first time unit belongs to the first signal and can be recorded as RX 1-2-1 Among them, 'RX 1-2-1 It can be understood as: the radio frequency signal received by the second antenna sub-array of the first communication device in the first time unit.

[0250] That is, the second antenna sub-array realizes the receiving function in the first time unit, for receiving the radio frequency signal RX 1-2-1 .

[0251] In another aspect, the first transmitting circuit is configured to process the third signal in the first time unit to obtain the fourth signal. Accordingly, the third antenna subarray is configured to transmit the fourth signal in the first time unit, thereby achieving a transmitting function.

[0252] In this application, the radio frequency signal sent by the third antenna subarray in the first time unit belongs to the fourth signal and can be recorded as TX 1-3-1 Among them, 'TX 1-3-1 It can be understood as: the radio frequency signal sent by the third antenna subarray of the first communication device in the first time unit.

[0253] That is, the third antenna subarray implements the sending function in the first time unit, for sending the radio frequency signal TX 1-3-1 .

[0254] In summary, during the first time unit, the first communication device receives via the second antenna subarray and transmits via the third antenna subarray, thereby achieving duplex communication. Furthermore, the first antenna subarray neither transmits nor receives the first RF signal, thereby achieving isolation and improving communication performance.

[0255] It should be noted that, when the first communication device further includes a first switch, a second switch, and a third switch, the working states of the three switches in the first time unit are as follows:

[0256] On the one hand, the first end and the fourth end of the first switch are disconnected, so that the first antenna subarray does not send or receive the first radio frequency signal, thereby achieving an isolation effect.

[0257] On the other hand, the second end and the third end of the second switch are conductive, and the second end and the third end of the third switch are conductive, so that the first signal is transmitted from the second antenna sub-array to the first receiving circuit through the second switch and the third switch, thereby realizing the receiving function.

[0258] On the other hand, the third end and the fourth end of the first switch are connected, so that the fourth signal is transmitted from the first transmitting circuit to the third antenna subarray through the first switch, thereby realizing the transmission function.

[0259] It should be noted that in Case 1, switch X is similar to the sixth switch in Example 4, and the second and third terminals of switch X are conductive. In this case, the signal processed by the first transmitting circuit is transmitted to the third antenna subarray via circulator Y and the first switch.

[0260] Case 2, the working status of each antenna subarray in the first communication device in the second time unit:

[0261] In case 2, the second time unit is a downlink time unit in a non-SBFD time unit.

[0262] The first transmitting circuit is configured to process the fifth signal in the second time unit to obtain a sixth signal. The first antenna subarray is configured to transmit the sixth signal in the second time unit. The third antenna subarray is configured to transmit the sixth signal in the second time unit.

[0263] by Figure 8 For example, the first transmitting circuit performs digital-to-analog conversion and amplification processing on the fifth signal to obtain a sixth signal.

[0264] In this application, the radio frequency signal sent by the first antenna subarray in the second time unit belongs to the sixth signal and can be recorded as TX 1-1-2 Among them, 'TX 1-1-2 It can be understood as: the radio frequency signal sent by the first antenna subarray of the first communication device in the second time unit.

[0265] That is, the first antenna subarray implements the sending function in the second time unit, for sending the radio frequency signal TX 1-1-2 .

[0266] In this application, the radio frequency signal sent by the third antenna subarray in the second time unit belongs to the sixth signal and can be recorded as TX 1-3-2 Among them, 'TX 1-3-2 It can be understood as: the radio frequency signal sent by the third antenna subarray of the first communication device in the second time unit.

[0267] That is, the third antenna subarray implements the sending function in the second time unit, for sending the radio frequency signal TX 1-3-2 .

[0268] In scenario 2, it can be understood that in the second time unit, the first antenna subarray transmits the sixth signal only when the third antenna subarray is transmitting. This increases the number of antenna subarrays used for signal transmission, and accordingly, the antenna panel area used for signal transmission increases, increasing signal gain and improving downlink coverage.

[0269] It should be noted that, when the first communication device further includes a first switch, the working state of the first switch in the second time unit is as follows:

[0270] On the one hand, the first end and the fourth end of the first switch are connected, so that the sixth signal is transmitted from the first transmitting circuit to the first antenna subarray through the first switch, so as to realize the signal sending function through the first antenna subarray.

[0271] On the other hand, the third end and the fourth end of the first switch are connected, so that the sixth signal is transmitted from the first transmitting circuit to the third antenna subarray through the first switch, thereby realizing the signal sending function through the third antenna subarray.

[0272] Optionally, in case 2, as an example, the second antenna sub-array is used to send the sixth signal in the second time unit.

[0273] In this application, the radio frequency signal sent by the second antenna sub-array in the second time unit belongs to the sixth signal and can be recorded as TX 1-2-2 Among them, 'TX 1-2-2 It can be understood as: the radio frequency signal sent by the second antenna sub-array of the first communication device in the second time unit.

[0274] That is, the second antenna sub-array realizes the sending function in the second time unit, for sending the radio frequency signal TX 1-2-2 .

[0275] In case 2, it can be understood that in the second time unit, the second antenna subarray sends the sixth signal only when both the first antenna subarray and the third antenna subarray are sending signals, thereby achieving the effect of further improving downlink coverage.

[0276] It should be noted that, when the first communication device further includes a first switch, the operating state of the first switch in the second time unit is as follows: the second end and the fourth end of the first switch are conductive, so that the sixth signal is transmitted from the first transmitting circuit to the second antenna sub-array through the first switch, thereby realizing a signal transmission function through the second antenna sub-array.

[0277] Optionally, in case 2, as another example, the second antenna sub-array is configured to not send the sixth signal and not receive the second radio frequency signal in the second time unit.

[0278] It can be understood that during the second time unit, the second antenna sub-array is not working. In other words, during the second time unit, the first communication device sends the sixth signal through the first antenna sub-array and the third antenna sub-array.

[0279] It should be noted that when the first communication device further includes a first switch, the operating state of the first switch during the second time unit is as follows: the second end and the fourth end of the first switch are disconnected, so that the second antenna sub-array does not transmit the sixth signal and does not receive the second radio frequency signal. In this manner, the second antenna sub-array is inoperative.

[0280] It should be noted that, in the present application, as another possible example, the first antenna subarray is configured not to send the sixth signal and not to receive the radio frequency signal RX in the second time unit. 1-1-2 It can be understood that, in the second time unit, the first antenna subarray does not work, the second antenna subarray does not work, and the third antenna subarray is used to send the sixth signal, thereby achieving the sending function.

[0281] It should be noted that in scenario 2, switch X is similar to the sixth switch in embodiment 4, and the second end of switch X is conductively connected to the third end, or the first end of switch X is conductively connected to the third end. In this case, the signal processed by the first transmitting circuit is transmitted through the circulator Y and the first switch to different antenna subarrays, such as one or more of the first antenna subarray, the second antenna subarray, and the third antenna subarray.

[0282] Case 3: Working status of each antenna subarray in the first communication device in the third time unit:

[0283] In case 3, the third time unit is an uplink time unit in the non-SBFD time unit.

[0284] The first antenna subarray is used to receive the seventh signal in the third time unit, the second antenna subarray is used to receive the eighth signal in the third time unit, and the first receiving circuit is used to process the seventh signal and the eighth signal in the third time unit.

[0285] by Figure 8 For example, the first receiving circuit amplifies and performs digital-to-analog conversion on the seventh signal and the eighth signal.

[0286] In this application, the radio frequency signal received by the first antenna subarray in the third time unit belongs to the seventh signal and can be recorded as RX 1-1-3 Among them, 'RX 1-1-3 It can be understood as: the radio frequency signal received by the first antenna subarray of the first communication device in the third time unit.

[0287] That is, the first antenna subarray implements a receiving function in the third time unit, for receiving the radio frequency signal RX 1-1-3 .

[0288] In this application, the radio frequency signal received by the second antenna sub-array in the third time unit belongs to the eighth signal and can be recorded as RX 1-2-3 Among them, 'RX 1-2-3 It can be understood as: the radio frequency signal received by the second antenna sub-array of the first communication device in the third time unit.

[0289] That is, the second antenna sub-array realizes the receiving function in the third time unit, and is used to receive the radio frequency signal RX 1-2-3 .

[0290] In scenario 3, it can be understood that during the third time unit, the first antenna subarray performs signal reception only when the second antenna subarray is already receiving signals. This increases the number of antenna subarrays used for signal reception, and accordingly, the antenna panel area used for signal reception is increased, thereby improving uplink coverage.

[0291] It should be noted that, when the first communication device further includes a first switch, the working state of the first switch in the third time unit is as follows:

[0292] On the one hand, the first end and the fourth end of the first switch are connected, so that the seventh signal is transmitted from the first antenna subarray to the first receiving circuit through the first switch, so as to realize the signal receiving function through the first antenna subarray.

[0293] On the other hand, the second end and the fourth end of the first switch are connected, so that the eighth signal is transmitted from the second antenna sub-array to the first receiving circuit through the first switch, thereby realizing a signal receiving function through the second antenna sub-array.

[0294] Optionally, in case 3, as an example, the third antenna subarray is configured to receive the ninth signal in the third time unit. Accordingly, the first receiving circuit is further configured to process the ninth signal in the third time unit.

[0295] In this application, the radio frequency signal received by the third antenna subarray in the third time unit belongs to the ninth signal and can be recorded as RX 1-3-3 Among them, 'RX 1-3-3 It can be understood as: the radio frequency signal received by the third antenna subarray of the first communication device in the third time unit.

[0296] That is, the third antenna subarray implements a receiving function in the third time unit, for receiving the radio frequency signal RX 1-3-3 .

[0297] In case 3, it can be understood that in the third time unit, the third antenna subarray receives signals only when both the first antenna subarray and the second antenna subarray receive signals, thereby achieving the effect of further improving uplink coverage.

[0298] It should be noted that when the first communication device also includes a first switch, the working state of the first switch in the third time unit is as follows: the third end and the fourth end of the first switch are connected, so that the ninth signal is transmitted from the third antenna subarray to the first receiving circuit through the first switch, so as to realize the signal receiving function through the third antenna subarray.

[0299] Optionally, in case 3, as another example, the third antenna subarray is configured to not send the second radio frequency signal and not receive the ninth signal in the third time unit.

[0300] It can be understood that, during the third time unit, the third antenna subarray is not working. In other words, during the third time unit, the first communication device receives signals through the first antenna subarray and the second antenna subarray.

[0301] It should be noted that when the first communication device further includes a first switch, the operating state of the first switch during the third time unit is as follows: the third terminal and the fourth terminal of the first switch are disconnected, so that the third antenna subarray does not transmit the third radio frequency signal and does not receive the ninth signal. In this manner, the third antenna subarray is inoperative.

[0302] It should be noted that, in the present application, as another possible example, the first antenna subarray is configured not to send the radio frequency signal TX in the third time unit. 1-1-3 It can be understood that in the third time unit, the first antenna subarray does not work, the third antenna subarray does not work, and the second antenna subarray is used to receive the eighth signal, thereby achieving the receiving function.

[0303] It should be noted that in case 3, switch X is similar to the sixth switch in embodiment 4, and the first end and the third end of switch X are conductive. In this case, signals received by different antenna subarrays (e.g., one or more of the first antenna subarray, the second antenna subarray, and the third antenna subarray) are transmitted to the first receiving circuit via the first switch, the circulator Y, and the switch X.

[0304] Example 3

[0305] The embodiment of the present application provides a communication device. The communication device of the third embodiment is referred to as a second communication device.

[0306] The second communication device includes a first radio frequency circuit and an antenna panel. The antenna panel includes a first area, a second area and a third area. Figure 6b shown.

[0307] The first radio frequency circuit includes a first transmitting circuit and a first receiving circuit. Figure 9 shown.

[0308] like Figure 9 As shown, the first transmitting circuit includes a first digital circuit, a first analog circuit, a second analog circuit, and a third analog circuit. The first digital circuit is connected to the first analog circuit, the second analog circuit, and the third analog circuit, respectively. The first analog circuit is connected to the first antenna subarray. The second analog circuit is connected to the second antenna subarray. The third analog circuit is connected to the third antenna subarray. The first antenna subarray, the second antenna subarray, and the third antenna subarray are described in the first embodiment and are not further described here.

[0309] like Figure 9 As shown, the first receiving circuit includes a second digital circuit, a fourth analog circuit, a fifth analog circuit, and a sixth analog circuit. The second digital circuit is connected to the fourth analog circuit, the fifth analog circuit, and the sixth analog circuit, respectively. The fourth analog circuit is connected to the first antenna subarray. The fifth analog circuit is connected to the second antenna subarray. The sixth analog circuit is connected to the third antenna subarray.

[0310] That is, in the first transmitting circuit, antenna subarrays in different regions are connected to their own analog circuits, and the analog circuits connected to antenna subarrays in different regions are connected to the same digital circuit. When the first digital circuit performs processing, the transmitting function can be implemented by different analog circuits and the antenna subarrays corresponding to these analog circuits. For example, the transmitting function can be implemented by the third analog circuit and the third antenna subarray. In another example, the transmitting function can be implemented by the third analog circuit and the third antenna subarray, and by the first analog circuit and the first antenna subarray. In another example, the transmitting function can be implemented by the first analog circuit and the first antenna subarray, the second analog circuit and the second antenna subarray, and the third analog circuit and the third antenna subarray.

[0311] Similarly, in the first receiving circuit, antenna subarrays in different regions are connected to their own analog circuits, and the analog circuits connected to antenna subarrays in different regions are connected to the same digital circuit. When the second digital circuit performs processing, the transmitting function can be implemented by different analog circuits and the antenna subarrays corresponding to these analog circuits. For example, the receiving function can be implemented by the fifth analog circuit and the second antenna subarray. In another example, the receiving function can be implemented by the fifth analog circuit and the second antenna subarray, and by the fourth analog circuit and the first antenna subarray. In another example, the receiving function can be implemented by the fourth analog circuit and the first antenna subarray, the fifth analog circuit and the second antenna subarray, and the sixth analog circuit and the third antenna subarray.

[0312] In addition, in the third communication device, the fourth switch and the fifth switch are not set at the front end of the RF channel, but are set inside the RF channel, thereby avoiding the impact of the insertion loss of the switching switch at the front end of the RF channel on the RF circuit, which helps to improve system performance.

[0313] In some embodiments, the second communication device further includes a fourth switch. Figure 9 As shown, a first end of the fourth switch is connected to the input end of the first analog circuit. A second end of the fourth switch is connected to the input end of the second analog circuit. A third end of the fourth switch is connected to the input end of the third analog circuit. A fourth end of the fourth switch is connected to the output end of the first digital circuit.

[0314] In the present application, the fourth switch can be understood as an impedance control switch within the RF channel.

[0315] In this way, the working states of the first analog circuit, the second analog circuit, and the third analog circuit can be controlled by the fourth switch, so that at least one of the three antenna subarrays (such as the first antenna subarray, the second antenna subarray, and the third antenna subarray) can realize the function of transmitting radio frequency signals.

[0316] In some embodiments, the second communication device further includes a fifth switch. Figure 9 As shown, a first end of the fifth switch is connected to the output end of the fourth analog circuit. A second end of the fifth switch is connected to the output end of the fifth analog circuit. A third end of the fifth switch is connected to the output end of the sixth analog circuit. A fourth end of the fifth switch is connected to the input end of the second digital circuit.

[0317] In the present application, the fifth switch can be understood as an impedance control switch within the RF channel.

[0318] In this way, the working states of the fourth analog circuit, the fifth analog circuit, and the sixth analog circuit can be controlled by the fifth switch, so that at least one of the three antenna subarrays (such as the first antenna subarray, the second antenna subarray, and the third antenna subarray) can realize the function of receiving radio frequency signals.

[0319] Next, the working status of each antenna subarray in the second communication device at different time units is introduced:

[0320] Case 4: Working status of each antenna subarray in the second communication device in the first time unit:

[0321] In case 4, the first time unit belongs to the SBFD time unit.

[0322] In one aspect, the first analog circuit is configured to not perform amplification processing during a first time unit, so that the first antenna subarray does not transmit a fourth radio frequency signal during the first time unit. Furthermore, the fourth analog circuit is configured to not perform amplification processing during the first time unit, so that the first antenna subarray does not receive a fifth radio frequency signal during the first time unit.

[0323] In this application, the radio frequency signal sent by the first antenna subarray in the first time unit belongs to the fourth radio frequency signal and can be recorded as TX 2-1-1 Among them, 'TX 2-1-1 It can be understood as: the radio frequency signal sent by the first antenna subarray of the second communication device in the first time unit.

[0324] In this application, the radio frequency signal received by the first antenna subarray in the first time unit belongs to the fifth radio frequency signal and can be recorded as RX 2-1-1 Among them, 'RX 2-1-1 It can be understood as: the radio frequency signal received by the first antenna subarray of the second communication device in the first time unit.

[0325] That is, the first antenna subarray does not send the radio frequency signal TX in the first time unit. 2-1-1 , nor does it receive RF signals RX 2-1-1 It can be understood that the first antenna subarray does not work in the first time unit, thereby achieving an isolation effect.

[0326] In another aspect, the second antenna subarray is configured to receive a tenth signal in a first time unit. The fifth analog circuit is configured to amplify the tenth signal in the first time unit to obtain an eleventh signal. The second digital circuit is configured to perform analog-to-digital conversion on the eleventh signal in the first time unit to obtain a twelfth signal, thereby achieving a receiving function.

[0327] In this application, the radio frequency signal received by the second antenna sub-array in the first time unit belongs to the tenth signal and can be recorded as RX 2-2-1 Among them, 'RX 2-2-1 It can be understood as: the radio frequency signal received by the second antenna sub-array of the second communication device in the first time unit.

[0328] That is, the second antenna sub-array realizes the receiving function in the first time unit, for receiving the radio frequency signal RX 2-2-1 .

[0329] In another aspect, the first digital circuit is configured to perform digital-to-analog conversion on the thirteenth signal in the first time unit to obtain a fourteenth signal. The third analog circuit is configured to amplify the fourteenth signal in the first time unit to obtain a fifteenth signal. The third antenna subarray is configured to transmit the fifteenth signal in the first time unit, thereby achieving a transmission function.

[0330] In this application, the radio frequency signal sent by the third antenna subarray in the first time unit belongs to the fifteenth signal and can be recorded as TX 2-3-1 Among them, 'TX 2-3-1 ' can be understood as: the radio frequency signal sent by the third antenna subarray of the second communication device in the first time unit. That is, the third antenna subarray implements the sending function in the first time unit, for sending the radio frequency signal TX 2-3-1 .

[0331] In summary, during the first time unit, the second communication device receives signals via the second digital circuit, the fifth analog circuit, and the second antenna subarray, and transmits signals via the first digital circuit, the third analog circuit, and the third antenna subarray, thereby achieving duplex communication. Furthermore, the first antenna subarray does not transmit the fourth RF signal and does not receive the fifth RF signal, thereby achieving isolation and improving communication performance.

[0332] It should be noted that, when the second communication device further includes a fourth switch and a fifth switch, the working states of the two switches in the first time unit are as follows:

[0333] On the one hand, the first and fourth terminals of the fourth switch are disconnected, so that the first analog circuit does not perform amplification processing. Consequently, the first antenna subarray does not transmit signals. Furthermore, the first and fourth terminals of the fifth switch are disconnected, so that the fourth analog circuit does not perform amplification processing. Consequently, the first antenna subarray does not receive signals. In other words, the first antenna subarray is inoperative, achieving an isolation effect.

[0334] On the other hand, the second end and the fourth end of the fifth switch are connected, so that the eleventh signal is transmitted from the fifth analog circuit to the second digital circuit through the fifth switch to achieve a receiving function.

[0335] On the other hand, the third end and the fourth end of the fourth switch are connected, so that the fourteenth signal is transmitted from the first digital circuit to the third analog circuit through the fourth switch to achieve the sending function.

[0336] In scenario 4, switch X1 is similar to the sixth switch in Example 4, with the first end of switch X1 conductively connected to the third end, or the second end of switch X1 conductively connected to the third end. Switch X2 is similar to the seventh switch in Example 4, with the first end of switch X2 conductively connected to the third end. In this scenario, the signal received by the second antenna subarray is transmitted to the fifth analog circuit via circulator Y2 and switch X2. Switch X3 is similar to the eighth switch in Example 4, with the second end of switch X3 conductively connected to the third end. In this scenario, the signal processed by the third analog circuit is transmitted to the third antenna subarray via circulator Y3.

[0337] Case 5, the working status of each antenna subarray in the second communication device in the second time unit:

[0338] In case 5, the second time unit is a downlink time unit in the non-SBFD time unit.

[0339] In one aspect, the first digital circuit is configured to perform digital-to-analog conversion on the sixteenth signal in the second time unit to obtain a seventeenth signal. The first analog circuit is configured to amplify the seventeenth signal in the second time unit to obtain an eighteenth signal. The first antenna subarray is configured to transmit the eighteenth signal in the second time unit.

[0340] In another aspect, the third analog circuit is used to amplify the seventeenth signal in the second time unit to obtain the nineteenth signal. The third antenna subarray is used to transmit the nineteenth signal in the second time unit.

[0341] In this application, the radio frequency signal sent by the first antenna subarray in the second time unit belongs to the eighteenth signal and can be recorded as TX 2-1-2 Among them, 'TX 2-1-2 It can be understood as: the radio frequency signal sent by the first antenna subarray of the second communication device in the second time unit.

[0342] That is, the first antenna subarray implements the sending function in the second time unit, for sending the radio frequency signal TX 2-1-2 .

[0343] In this application, the radio frequency signal sent by the third antenna subarray in the second time unit belongs to the nineteenth signal and can be recorded as TX 2-3-2 Among them, 'TX 2-3-2 ' can be understood as: the radio frequency signal sent by the third antenna subarray of the second communication device in the second time unit. That is, the third antenna subarray implements the sending function in the second time unit, for sending the radio frequency signal TX 1-3-2 .

[0344] In scenario 5, it can be understood that in the second time unit, the first antenna subarray transmits signals only when the third antenna subarray transmits signals. This increases the number of antenna subarrays used for signal transmission, and accordingly, the antenna panel area used for signal transmission increases, increasing signal gain and improving downlink coverage.

[0345] It should be noted that, when the second communication device further includes a fourth switch, the working state of the fourth switch in the second time unit is as follows:

[0346] On the one hand, the first end and the fourth end of the fourth switch are connected, so that the seventeenth signal is transmitted from the first digital circuit to the first analog circuit through the fourth switch, thereby enabling the first antenna subarray to realize the signal sending function.

[0347] On the other hand, the third end and the fourth end of the fourth switch are connected, so that the seventeenth signal is transmitted from the first digital circuit to the third analog circuit through the fourth switch, thereby enabling the third antenna subarray to realize the signal sending function.

[0348] Optionally, in situation 5, as an example, the second analog circuit is used to amplify the seventeenth signal in the second time unit to obtain the twentieth signal. Accordingly, the second antenna sub-array is used to send the twentieth signal in the second time unit.

[0349] In this application, the radio frequency signal sent by the second antenna sub-array in the second time unit belongs to the twentieth signal and can be recorded as TX 2-2-2 Among them, 'TX 2-2-2 ' can be understood as: the second antenna sub-array of the second communication device transmits a radio frequency signal in the second time unit. That is, the second antenna sub-array implements a transmitting function in the second time unit, for transmitting a radio frequency signal TX 2-2-2 .

[0350] In case 5, it can be understood that in the second time unit, the second antenna subarray sends the twentieth signal only when both the first antenna subarray and the third antenna subarray are sending signals, thereby further improving downlink coverage.

[0351] It should be noted that, when the second communication device further includes a fourth switch, the operating state of the fourth switch in the second time unit is as follows: the second end and the fourth end of the fourth switch are conductive, so that the seventeenth signal is transmitted from the first digital circuit to the second analog circuit through the fourth switch, thereby realizing the signal sending function through the second antenna sub-array.

[0352] Optionally, in scenario 5, as another example, the second analog circuit is configured to not perform amplification processing in the second time unit, so that the second antenna sub-array does not transmit the twentieth signal in the second time unit. Furthermore, the fifth analog circuit is configured to not perform amplification processing in the second time unit, so that the second antenna sub-array does not receive the sixth radio frequency signal in the second time unit.

[0353] It can be understood that during the second time unit, the second antenna sub-array is not working. In other words, during the second time unit, the second communication device transmits signals via the first antenna sub-array and the third antenna sub-array.

[0354] It should be noted that if the second communication device further includes a fourth switch, the fourth switch operates in the following manner during the second time unit: the second end of the fourth switch is disconnected from the fourth end, thereby preventing the second analog circuit from performing amplification processing, and thus preventing the second antenna sub-array from transmitting the twentieth signal. If the second communication device further includes a fifth switch, the fifth switch operates in the following manner during the second time unit: the second end of the fifth switch is disconnected from the fourth end, thereby preventing the fifth analog circuit from performing amplification processing, and thus preventing the second antenna sub-array from receiving the sixth radio frequency signal. In this manner, the second antenna sub-array is rendered inoperative.

[0355] It should be noted that, in the present application, as another possible example, the first antenna subarray is configured not to send the eighteenth signal and not to receive the radio frequency signal RX in the second time unit. 2-1-2 It can be understood that, in the second time unit, the first antenna subarray does not work, the second antenna subarray does not work, and the third antenna subarray is used to send the nineteenth signal, thereby achieving the sending function.

[0356] It should be noted that in scenario 5, switch X1 is similar to the sixth switch in Example 4. The second and third terminals of switch X1 are conductively connected, or the first and third terminals of switch X1 are conductively connected. In this case, the signal processed by the first analog circuit is transmitted to the first antenna subarray via circulator Y1. Switch X2 is similar to the seventh switch in Example 4. The second and third terminals of switch X2 are conductively connected, or the first and third terminals of switch X2 are conductively connected. In this case, the signal processed by the second analog circuit is transmitted to the second antenna subarray via circulator Y2. Switch X3 is similar to the eighth switch in Example 4. The second and third terminals of switch X3 are conductively connected, or the first and third terminals of switch X3 are conductively connected. In this case, the signal processed by the third analog circuit is transmitted to the third antenna subarray via circulator Y3.

[0357] Case 6: Working status of each antenna subarray in the second communication device in the third time unit:

[0358] In case 6, the third time unit is an uplink time unit in the non-SBFD time unit.

[0359] In one aspect, the first antenna subarray is configured to receive a twenty-first signal in a third time unit, and the fourth analog circuit is configured to amplify the twenty-first signal in the third time unit to obtain a twenty-second signal.

[0360] On the other hand, the second antenna sub-array is used to receive a twenty-third signal in a third time unit. The fifth analog circuit is used to amplify the twenty-third signal in the third time unit to obtain a twenty-fourth signal.

[0361] Correspondingly, the second digital circuit is used to perform analog-to-digital conversion on the twenty-second signal and the twenty-fourth signal in the third time unit.

[0362] In this application, the radio frequency signal received by the first antenna subarray in the third time unit belongs to the twenty-first signal and can be recorded as RX 2-1-3 Among them, 'RX 2-1-3 It can be understood as: the radio frequency signal received by the first antenna subarray of the second communication device in the third time unit.

[0363] That is, the first antenna subarray implements a receiving function in the third time unit, for receiving the radio frequency signal RX 2-1-3 .

[0364] In this application, the radio frequency signal received by the second antenna sub-array in the third time unit belongs to the twenty-third signal and can be recorded as RX 2-2-3 Among them, 'RX 2-2-3 It can be understood as: the radio frequency signal received by the second antenna sub-array of the second communication device in the third time unit.

[0365] That is, the second antenna sub-array realizes the receiving function in the third time unit, and is used to receive the radio frequency signal RX 2-2-3 .

[0366] In scenario 6, it can be understood that during the third time unit, the first antenna subarray receives the twenty-first signal only when the second antenna subarray is receiving signals. This increases the number of antenna subarrays used for signal reception, and accordingly, the antenna panel area used for signal reception is increased, thereby improving uplink coverage.

[0367] It should be noted that, when the second communication device further includes a fifth switch, the working state of the fifth switch in the third time unit is as follows:

[0368] On the one hand, the first end and the fourth end of the fifth switch are connected, so that the twenty-second signal is transmitted from the fourth analog circuit to the second digital circuit through the fourth switch, so as to realize the signal receiving function through the first antenna subarray.

[0369] On the other hand, the second end and the fourth end of the fifth switch are connected, so that the twenty-fourth signal is transmitted from the fifth analog circuit to the second digital circuit through the fourth switch, so as to realize the signal receiving function through the second antenna sub-array.

[0370] Optionally, in scenario 6, as an example, the third antenna subarray is configured to receive a 25th signal in a third time unit. The sixth analog circuit is configured to amplify the 25th signal in the third time unit to obtain a 26th signal. The second digital circuit is further configured to perform analog-to-digital conversion on the 26th signal in the third time unit.

[0371] In this application, the radio frequency signal received by the third antenna subarray in the third time unit belongs to the twenty-fifth signal and can be recorded as RX 2-3-3 Among them, 'RX 2-3-3 It can be understood as: the radio frequency signal received by the third antenna subarray of the second communication device in the third time unit.

[0372] That is, the third antenna subarray implements a receiving function in the third time unit, for receiving the radio frequency signal RX 2-3-3 .

[0373] In case 6, it can be understood that in the third time unit, the third antenna subarray receives the twenty-fifth signal only when both the first antenna subarray and the second antenna subarray are receiving signals, thereby achieving the effect of further improving uplink coverage.

[0374] It should be noted that when the second communication device also includes a fifth switch, the working state of the fifth switch in the third time unit is as follows: the third end and the fourth end of the fifth switch are connected, so that the twenty-sixth signal is transmitted from the sixth analog circuit to the second digital circuit through the fifth switch, so as to realize the signal receiving function through the third antenna subarray.

[0375] Optionally, in scenario 6, as another example, the third analog circuit is configured to not perform amplification processing in the third time unit, so that the third antenna subarray does not transmit the seventh radio frequency signal in the third time unit. Furthermore, the sixth analog circuit is configured to not perform amplification processing in the third time unit, so that the third antenna subarray does not receive the twenty-fifth signal in the third time unit.

[0376] It can be understood that, during the third time unit, the third antenna subarray is not working. In other words, during the third time unit, the second communication device receives signals through the first antenna subarray and the second antenna subarray.

[0377] It should be noted that if the second communication device further includes a fourth switch, the fourth switch operates in the following manner during the third time unit: the third and fourth terminals of the fourth switch are disconnected, so that the third analog circuit does not perform amplification processing. Consequently, the third antenna subarray does not transmit the seventh RF signal. If the second communication device further includes a fifth switch, the fifth switch operates in the following manner during the third time unit: the third and fourth terminals of the fifth switch are disconnected, so that the sixth analog circuit does not perform amplification processing. Consequently, the third antenna subarray does not receive the twenty-fifth signal. In this manner, the third antenna subarray is inoperative.

[0378] It should be noted that, in the present application, as another possible example, the first antenna subarray is configured not to send the radio frequency signal TX in the third time unit. 2-1-3 It can be understood that in the third time unit, the first antenna subarray does not work, the third antenna subarray does not work, and the second antenna subarray is used to receive the twenty-third signal, thereby achieving the receiving function.

[0379] It should be noted that in scenario 6, switch X1 is similar to the sixth switch in Example 4, with the first terminal and the third terminal of switch X1 conductively connected. In this scenario, the signal received by the first antenna subarray is transmitted to the fourth analog circuit via circulator Y1 and switch X1. Switch X2 is similar to the seventh switch in Example 4, with the first terminal and the third terminal of switch X2 conductively connected. In this scenario, the signal received by the second antenna subarray is transmitted to the fifth analog circuit via circulator Y2 and switch X2. Switch X3 is similar to the eighth switch in Example 4, with the first terminal and the third terminal of switch X3 conductively connected. In this scenario, the signal received by the third antenna subarray is transmitted to the sixth analog circuit via circulator Y3 and switch X3.

[0380] Example 4

[0381] The embodiment of the present application provides a communication device. The communication device of the fourth embodiment is referred to as a third communication device.

[0382] The third communication device includes a first radio frequency circuit, a second radio frequency circuit, a third radio frequency circuit and an antenna panel. The antenna panel includes a first area, a second area and a third area, such as Figure 6b shown.

[0383] like Figure 10 As shown, the first radio frequency circuit includes a first transmitting circuit and a first receiving circuit. The first transmitting circuit is connected to the first antenna subarray. The first receiving circuit is connected to the first antenna subarray.

[0384] like Figure 10 As shown, the second radio frequency circuit includes a second transmitting circuit and a second receiving circuit. The second transmitting circuit is connected to the second antenna sub-array. The second receiving circuit is connected to the second antenna sub-array.

[0385] like Figure 10 As shown, the third radio frequency circuit includes a third transmitting circuit and a third receiving circuit. The third transmitting circuit is connected to the third antenna subarray. The third receiving circuit is connected to the third antenna subarray.

[0386] The first antenna sub-array, the second antenna sub-array and the third antenna sub-array may refer to the introduction of the first embodiment and will not be described in detail.

[0387] That is, antenna subarrays in different areas are connected to their own transmit circuits. When different transmit circuits perform processing, the transmit function can be implemented by the antenna subarrays to which the transmit circuits are connected. For example, the transmit function can be implemented by the third transmit circuit and the third antenna subarray. Another example is the transmit function implemented by the third transmit circuit and the third antenna subarray, and the first transmit circuit and the first antenna subarray. Another example is the transmit function implemented by the first transmit circuit and the first antenna subarray, the second transmit circuit and the second antenna subarray, and the third transmit circuit and the third antenna subarray.

[0388] Similarly, antenna subarrays in different areas are connected to their own receiving circuits. When different receiving circuits perform processing, the receiving function can be implemented by the antenna subarrays to which the receiving circuits are connected. For example, the receiving function can be implemented by the second receiving circuit and the second antenna subarray. In another example, the receiving function can be implemented by the second receiving circuit and the second antenna subarray, and by the first receiving circuit and the first antenna subarray. In another example, the receiving function can be implemented by the first receiving circuit and the first antenna subarray, the second receiving circuit and the second antenna subarray, and the third receiving circuit and the third antenna subarray.

[0389] In some embodiments, the third communication device further includes a sixth switch. Figure 10 As shown, a first end of the sixth switch is connected to the input end of the first receiving circuit, a second end of the sixth switch is grounded, and a third end of the sixth switch is connected to the output end of the first transmitting circuit and the first antenna subarray.

[0390] by Figure 10 For example, the third end of the sixth switch is connected to the output end of the first transmitting circuit through the circulator 6, and the third end of the sixth switch is connected to the first antenna subarray through the circulator 6.

[0391] In this way, the working state of the first antenna subarray can be controlled by the sixth switch, such as controlling the first antenna subarray to implement the function of receiving radio frequency signals.

[0392] In some embodiments, the third communication device further includes a seventh switch. Figure 10 As shown, the first end of the seventh switch is connected to the input end of the second receiving circuit, the second end of the seventh switch is grounded, and the third end of the seventh switch is connected to the output end of the second transmitting circuit and the second antenna subarray.

[0393] by Figure 10 For example, the third end of the seventh switch is connected to the output end of the second transmitting circuit through the circulator 7 , and the third end of the seventh switch is connected to the second antenna sub-array through the circulator 7 .

[0394] In this way, the working state of the second antenna sub-array can be controlled by the seventh switch, such as controlling the second antenna sub-array to realize the receiving function of the radio frequency signal.

[0395] In some embodiments, the third communication device further includes an eighth switch. Figure 10 As shown, a first end of the eighth switch is connected to the input end of the third receiving circuit, a second end of the eighth switch is grounded, and a third end of the eighth switch is connected to the output end of the third transmitting circuit and the third antenna subarray.

[0396] by Figure 10 For example, the third end of the eighth switch is connected to the output end of the third transmitting circuit through the circulator 8, and the third end of the eighth switch is connected to the third antenna subarray through the circulator 8.

[0397] In this way, the working state of the third antenna subarray can be controlled by the eighth switch, such as controlling the third antenna subarray to implement the function of receiving radio frequency signals.

[0398] Next, the working status of each antenna sub-array in the third communication device at different time units is introduced.

[0399] Case 7, the working status of each antenna subarray in the third communication device in the first time unit:

[0400] In case 7, the first time unit belongs to the SBFD time unit.

[0401] In one aspect, the first transmitting circuit is configured to perform no processing during a first time unit so that the first antenna subarray does not transmit the eighth radio frequency signal. Furthermore, the first receiving circuit is configured to perform no processing during a first time unit so that the first antenna subarray does not receive the ninth radio frequency signal.

[0402] In this application, the radio frequency signal sent by the first antenna subarray in the first time unit belongs to the eighth radio frequency signal and can be recorded as TX 3-1-1 Among them, 'TX 3-1-1 It can be understood as: the radio frequency signal sent by the first antenna subarray of the third communication device in the first time unit.

[0403] In this application, the radio frequency signal received by the first antenna subarray in the first time unit belongs to the ninth radio frequency signal and can be recorded as RX 3-1-1 Among them, 'RX 3-1-1It can be understood as: the radio frequency signal received by the first antenna subarray of the third communication device in the first time unit.

[0404] That is, the first antenna subarray does not send the radio frequency signal TX in the first time unit. 3-1-1 , nor does it receive RF signals RX 3-1-1 It can be understood that the first antenna subarray does not work in the first time unit, thereby achieving an isolation effect.

[0405] In another aspect, the second antenna sub-array is used to receive the twenty-seventh signal in the first time unit. The second receiving circuit is used to process the twenty-seventh signal in the first time unit to obtain the twenty-eighth signal, thereby realizing the receiving function.

[0406] In this application, the radio frequency signal received by the second antenna sub-array in the first time unit belongs to the twenty-seventh signal and can be recorded as RX 3-2-1 Among them, 'RX 3-2-1 It can be understood as: the radio frequency signal received by the second antenna sub-array of the third communication device in the first time unit.

[0407] That is, the second antenna sub-array realizes the receiving function in the first time unit, for receiving the radio frequency signal RX 3-2-1 .

[0408] In another aspect, the third transmitting circuit is configured to process the twenty-ninth signal in the first time unit to obtain a thirtieth signal. The third antenna subarray is configured to transmit the thirtieth signal in the first time unit, thereby achieving a transmitting function.

[0409] In this application, the radio frequency signal sent by the third antenna subarray in the first time unit belongs to the 30th signal and can be recorded as TX 3-3-1 Among them, 'TX 3-3-1 It can be understood as: the radio frequency signal sent by the third antenna subarray of the third communication device in the first time unit.

[0410] That is, the third antenna subarray implements the sending function in the first time unit, for sending the radio frequency signal TX 3-3-1 .

[0411] In summary, during the first time unit, the third communication device receives signals via the second receiving circuit and the second antenna subarray, and transmits signals via the third transmitting circuit and the third antenna subarray, thereby achieving duplex communication. Furthermore, the first antenna subarray does not transmit the eighth radio frequency signal and does not receive the ninth radio frequency signal, thereby achieving isolation and improving communication performance.

[0412] It should be noted that, when the first communication device further includes a sixth switch, a seventh switch, and an eighth switch, the working states of the three switches in the first time unit are as follows:

[0413] On the one hand, the second end and the third end of the sixth switch are connected, so that the first receiving circuit does not perform processing, so that the first antenna subarray does not send the eighth radio frequency signal and does not receive the ninth radio frequency signal, thereby achieving an isolation effect.

[0414] On the other hand, the first end and the third end of the seventh switch are connected, so that the twenty-seventh signal is transmitted from the second antenna sub-array to the second receiving circuit through the seventh switch to achieve a receiving function.

[0415] On the other hand, the second terminal of the eighth switch is connected to the third terminal, or the first terminal of the eighth switch is connected to the third terminal. In this case, the thirtieth signal is transmitted from the third transmitting circuit to the third antenna subarray through the circulator 8 to achieve the transmission function.

[0416] Case 8, the working state of each antenna subarray in the third communication device in the second time unit:

[0417] In case 8, the second time unit is a downlink time unit in the non-SBFD time unit.

[0418] In one aspect, the first transmitting circuit is configured to process the thirty-first signal in the second time unit to obtain the thirty-second signal. The first antenna subarray is configured to transmit the thirty-second signal in the second time unit.

[0419] In another aspect, the third transmitting circuit is configured to process the thirty-third signal in the second time unit to obtain a thirty-fourth signal. The third antenna subarray is configured to transmit the thirty-fourth signal in the second time unit.

[0420] by Figure 10 For example, the first transmitting circuit performs digital-to-analog conversion and amplification processing on the thirty-first signal to obtain a thirty-second signal.

[0421] by Figure 10 For example, the third transmitting circuit performs digital-to-analog conversion and amplification processing on the thirty-third signal to obtain a thirty-fourth signal.

[0422] In this application, the radio frequency signal sent by the first antenna subarray in the second time unit belongs to the thirty-second signal and can be recorded as TX 3-1-2 Among them, 'TX 3-1-2 It can be understood as: the radio frequency signal sent by the first antenna subarray of the third communication device in the second time unit.

[0423] That is, the first antenna subarray implements the sending function in the second time unit, for sending the radio frequency signal TX3-1-2 .

[0424] In this application, the radio frequency signal sent by the third antenna subarray in the second time unit belongs to the thirty-fourth signal and can be recorded as TX 3-3-2 Among them, 'TX 3-3-2 It can be understood as: the radio frequency signal sent by the third antenna subarray of the third communication device in the second time unit.

[0425] That is, the third antenna subarray implements the sending function in the second time unit, for sending the radio frequency signal TX 3-3-2 .

[0426] In scenario 8, it can be understood that in the second time unit, the first antenna subarray transmits the thirty-second signal only when the third antenna subarray is transmitting a signal. This increases the number of antenna subarrays used for signal transmission, and accordingly, the antenna panel area used for signal transmission is increased, thereby improving downlink coverage.

[0427] It should be noted that, on the one hand, when the first communication device further includes a sixth switch, the operating state of the sixth switch in the second time unit is as follows: the second end of the sixth switch is conductively connected to the third end, or the first end of the sixth switch is conductively connected to the third end. In this case, the thirty-second signal is transmitted from the first transmitting circuit to the first antenna subarray via the circulator 6, thereby implementing a signal transmission function via the first antenna subarray.

[0428] On the other hand, when the first communication device further includes an eighth switch, the operating state of the eighth switch in the second time unit is as follows: the second end of the eighth switch is conductively connected to the third end, or the first end of the eighth switch is conductively connected to the third end. In this case, the thirty-fourth signal is transmitted from the third transmitting circuit to the third antenna subarray via the circulator 8, thereby implementing a signal transmission function via the third antenna subarray.

[0429] Optionally, in situation 8, as an example, the second transmitting circuit is configured to process the thirty-fifth signal in the second time unit to obtain a thirty-sixth signal. Accordingly, the second antenna sub-array is configured to send the thirty-sixth signal in the second time unit.

[0430] In this application, the radio frequency signal sent by the second antenna sub-array in the second time unit belongs to the thirty-sixth signal and can be recorded as TX 3-2-2 Among them, 'TX 3-2-2 It can be understood as: the radio frequency signal sent by the second antenna sub-array of the third communication device in the second time unit.

[0431] That is, the second antenna sub-array realizes the sending function in the second time unit, for sending the radio frequency signal TX 3-2-2 .

[0432] In case 8, it can be understood that in the second time unit, the second antenna subarray sends the thirty-sixth signal only when both the first antenna subarray and the third antenna subarray are sending signals, thereby further improving downlink coverage.

[0433] It should be noted that when the third communication device further includes a seventh switch, the operating state of the seventh switch during the second time unit is as follows: the second end of the seventh switch is conductively connected to the third end, or the first end of the seventh switch is conductively connected to the third end. In this case, the thirty-sixth signal is transmitted from the second transmitting circuit to the second antenna sub-array via the circulator 7, thereby implementing a signal transmission function via the second antenna sub-array.

[0434] Optionally, in scenario 8, as another example, the second transmitting circuit is configured to perform no processing during the second time unit so that the second antenna sub-array does not transmit the thirty-sixth signal. Furthermore, the second receiving circuit is configured to perform no processing during the second time unit so that the second antenna sub-array does not receive the tenth radio frequency signal.

[0435] It can be understood that during the second time unit, the second antenna sub-array is not working. In other words, during the second time unit, the third communication device transmits signals via the first antenna sub-array and the third antenna sub-array.

[0436] It should be noted that, in the case where the third communication device further includes a seventh switch, the working state of the seventh switch in the second time unit is as follows: the second end and the third end of the seventh switch are connected.

[0437] It should be noted that, in the present application, as another possible example, the first antenna subarray is configured not to send the thirty-second signal and not to receive the radio frequency signal RX in the second time unit. 3-1-2 It can be understood that, in the second time unit, the first antenna subarray does not work, the second antenna subarray does not work, and the third antenna subarray is used to send the thirty-fourth signal, thereby achieving the sending function.

[0438] Case 9, the working status of each antenna subarray in the third communication device in the third time unit:

[0439] In case 9, the third time unit is an uplink time unit in the non-SBFD time unit.

[0440] In one aspect, the first antenna subarray is configured to receive a thirty-seventh signal in a third time unit. The first receiving circuit is configured to process the thirty-seventh signal in the third time unit to obtain a thirty-eighth signal.

[0441] On the other hand, the second antenna sub-array is used to receive a thirty-ninth signal in a third time unit. The second receiving circuit is used to process the thirty-ninth signal in the third time unit to obtain a fortieth signal.

[0442] by Figure 10 For example, the first receiving circuit amplifies and performs digital-to-analog conversion on the thirty-seventh signal.

[0443] by Figure 10 For example, the second receiving circuit amplifies and performs digital-to-analog conversion on the thirty-ninth signal.

[0444] In this application, the radio frequency signal received by the first antenna subarray in the third time unit belongs to the thirty-seventh signal and can be recorded as RX 3-1-3 Among them, 'RX 3-1-3 It can be understood as: the radio frequency signal received by the first antenna subarray of the third communication device in the third time unit.

[0445] That is, the first antenna subarray implements a receiving function in the third time unit, for receiving the radio frequency signal RX 3-1-3 .

[0446] In this application, the radio frequency signal received by the second antenna sub-array in the third time unit belongs to the thirty-ninth signal and can be recorded as RX 3-2-3 Among them, 'RX 3-2-3 It can be understood as: the radio frequency signal received by the second antenna sub-array of the third communication device in the third time unit.

[0447] That is, the second antenna sub-array realizes the receiving function in the third time unit, and is used to receive the radio frequency signal RX 3-2-3 .

[0448] In scenario 9, it can be understood that during the third time unit, the first antenna subarray performs signal reception only when the second antenna subarray is already receiving signals. This increases the number of antenna subarrays used for signal reception, and accordingly, the antenna panel area used for signal reception is increased, thereby improving uplink coverage.

[0449] It should be pointed out that, on the one hand, when the third communication device also includes a sixth switch, the working state of the sixth switch in the third time unit is as follows: the first end and the third end of the sixth switch are connected, so that the thirty-seventh signal is transmitted from the first antenna subarray to the first receiving circuit through the sixth switch, so as to realize the signal receiving function through the first antenna subarray.

[0450] On the other hand, when the third communication device further includes a seventh switch, the operating state of the seventh switch in the third time unit is as follows: the first end and the third end of the seventh switch are conductive, so that the thirty-ninth signal is transmitted from the second antenna sub-array to the second receiving circuit through the seventh switch, thereby implementing a signal reception function through the second antenna sub-array.

[0451] Optionally, in case 9, as an example, the third antenna subarray is configured to receive a forty-first signal in a third time unit. The third receiving circuit is configured to process the forty-first signal in the third time unit to obtain a forty-second signal.

[0452] In this application, the radio frequency signal received by the third antenna subarray in the third time unit belongs to the forty-first signal and can be recorded as RX 3-3-3 Among them, 'RX 3-3-3 It can be understood as: the radio frequency signal received by the third antenna subarray of the third communication device in the third time unit.

[0453] That is, the third antenna subarray implements a receiving function in the third time unit, for receiving the radio frequency signal RX 1-3-3 .

[0454] In case 9, it can be understood that in the third time unit, the third antenna subarray performs signal reception only when both the first antenna subarray and the second antenna subarray receive signals, thereby achieving the effect of further improving uplink coverage.

[0455] It should be pointed out that when the third communication device also includes an eighth switch, the working state of the eighth switch in the third time unit is as follows: the first end and the third end of the eighth switch are connected, so that the forty-first signal is transmitted from the third antenna subarray to the third receiving circuit through the eighth switch, so as to realize the signal receiving function through the third antenna subarray.

[0456] Optionally, in scenario 9, as another example, the third transmitting circuit is configured to perform no processing during a third time unit, so that the third antenna subarray does not transmit the eleventh radio frequency signal. Furthermore, the third receiving circuit is configured to perform no processing during the third time unit, so that the third antenna subarray does not receive the forty-first signal.

[0457] It can be understood that, during the third time unit, the third antenna subarray is not working. In other words, during the third time unit, the third communication device receives signals through the first antenna subarray and the second antenna subarray.

[0458] It should be noted that, in the case where the third communication device further includes an eighth switch, the working state of the eighth switch in the third time unit is as follows: the second end and the third end of the eighth switch are connected.

[0459] It should be noted that, in the present application, as another possible example, the first antenna subarray is configured not to send the radio frequency signal TX in the third time unit. 3-1-3 It can be understood that in the third time unit, the first antenna subarray does not work, the third antenna subarray does not work, and the second antenna subarray is used to receive the thirty-ninth signal, thereby achieving the receiving function.

[0460] It should be noted that in this application, the number of antennas in the first antenna subarray, the second antenna subarray, and the third antenna subarray can be configured according to usage requirements to achieve a compromise between uplink and downlink capacity and coverage. For example, if the uplink capacity demand increases, better uplink coverage and uplink capacity can be achieved by configuring more antennas, such as configuring more second antenna subarrays, or increasing the number of antennas in the second antenna subarray. For another example, if the downlink capacity demand increases, better downlink coverage and downlink capacity can be achieved by configuring more antennas, such as configuring more third antenna subarrays, or increasing the number of antennas in the third antenna subarray.

[0461] It should be noted that in this application, Figure 7 and Figure 8 The switch X in can also be replaced by a through circuit. Similarly, Figure 9 One or more of the switches X1, X2 and X3 in the embodiment may also be replaced by a through circuit. Figure 10 One or more of the sixth switch, the seventh switch, and the eighth switch in the embodiment may also be replaced by a through circuit. The through circuit may include a wire, which is not limited in the embodiment of the present application.
