Technical Field

[0001] The present application relates to the technical field of communication equipment, and in particular to a communication device, system and signal processing method. Background Art

[0002] On a traditional antenna panel, it is divided into two areas. At a certain moment, the antenna subarray in one area is used to send RF signals, and the antenna subarray in the other area is used to receive RF signals.

[0003] However, the antenna subarray used to send radio frequency signals only occupies a portion of the antenna panel, resulting in low downlink coverage. Summary of the invention

[0004] In order to solve the above technical problems, the present application provides a communication device, system and signal processing method, which can ensure the spatial isolation of the antenna panel when sending and receiving radio frequency signals without increasing the wind resistance and expanding the antenna panel, and without losing the size of the antenna panel, thereby maintaining downlink coverage.

[0005] In order to achieve the above objectives, this application adopts the following technical solutions:

[0006] In a first aspect, a communication device is provided, the communication device comprising a first antenna panel and a second antenna panel. The first antenna panel is adjacent to the second antenna panel, and a first angle between the first antenna panel and the second antenna panel is less than 90 degrees. The first antenna panel is used to send a radio frequency signal TX at a first time unit. 1-1-1 The second antenna panel is used to receive a radio frequency signal RX at the first time unit. 1-2-1 The first time unit belongs to a time unit of sub-band full-duplex (SBFD).

[0007] As a result, on one hand, since the first antenna panel is adjacent to the second antenna panel and the first angle between the first antenna panel and the second antenna panel is less than 90 degrees, the communication device does not increase the wind resistance to expand the antenna panel.

[0008] On the other hand, in the same time unit, such as the first time unit, the first antenna panel is used to send the radio frequency signal TX 1-1-1 The second antenna panel is used to receive the radio frequency signal RX 1-2-1 In this way, the communication device ensures the spatial isolation between the first antenna panel for sending radio frequency signals and the second antenna panel for receiving radio frequency signals without sacrificing the size of the antenna panel, thereby maintaining downlink coverage.

[0009] In one possible design, the radio frequency signal TX1-1-1 The radio frequency signal RX belongs to the first sector. 1-2-1 A radio frequency signal belonging to a second sector, wherein the first sector is different from the second sector.

[0010] That is, in the first time unit, the radio frequency signal TX sent by the communication device 1-1-1 , and the radio frequency signal RX received by the communication device 1-2-1 , belonging to different sectors, thus laying the foundation for different communication devices to coordinate the transmission and reception of radio frequency signals in the same sector.

[0011] In one possible design, the first antenna panel is further configured to send a radio frequency signal TX at a second time unit. 1-1-2 , the RF signal TX 1-1-2 A radio frequency signal belonging to the first sector.

[0012] The second antenna panel is further configured not to send a radio frequency signal TX in the second time unit. 1-2-2 And does not receive RF signal RX 1-2-2 , the RF signal TX 1-2-2 and the RF signal RX 1-2-2 The radio frequency signal belongs to the second sector.

[0013] The second time unit is a non-SBFD downlink time unit.

[0014] That is, in the second time unit, the first antenna panel sends the radio frequency signal TX 1-1-2 , and the second antenna panel does not send or receive radio frequency signals. It can be seen that the second antenna panel does not have a transmitting function. In this way, the communication device does not need to connect a transmitting channel to the antenna subarray on the second antenna panel, thereby making the communication device lightweight and helping to reduce the cost of the communication device.

[0015] In one possible design, the first antenna panel is further configured to receive a radio frequency signal RX at a third time unit. 1-1-3 , the RF signal RX 1-1-3 A radio frequency signal belonging to the first sector.

[0016] The second antenna panel is further configured to receive a radio frequency signal RX at the third time unit. 1-2-3 , the RF signal RX 1-2-3 The radio frequency signal belongs to the second sector.

[0017] The third time unit is a non-SBFD uplink time unit.

[0018] That is, in the third time unit, the first antenna panel receives the radio frequency signal RX 1-1-3 It can be seen that the first antenna panel has a transceiver function. In this way, the communication device can use the reciprocity of transceiver to set parameters. For example, based on the parameters when the first antenna panel sends a radio frequency signal, the parameters when the first antenna panel and the second antenna panel receive a radio frequency signal are set, thereby improving the system communication performance.

[0019] In addition, during the third time unit, the second antenna panel receives the radio frequency signal RX 1-2-3 , which helps to improve the system's uplink coverage.

[0020] In one possible design, the communication device further includes a third antenna panel. The second antenna panel and the third antenna panel are both located on the same side of the first antenna panel, the first antenna panel is adjacent to the third antenna panel, and a second angle between the first antenna panel and the third antenna panel is less than 90 degrees. The third antenna panel is used to receive a radio frequency signal RX at the first time unit. 1-3-1 .

[0021] In this way, on the one hand, since the first antenna panel is adjacent to the second antenna panel and the first angle between the first antenna panel and the second antenna panel is less than 90 degrees, and the first antenna panel is adjacent to the third antenna panel and the second angle between the first antenna panel and the third antenna panel is less than 90 degrees, when the second antenna panel and the third antenna panel are located on the same side of the first antenna panel, the communication device does not increase the wind resistance to expand the antenna panel.

[0022] On the other hand, in the first time unit, the first antenna panel is used to send the radio frequency signal TX 1-1-1 The second antenna panel is used to receive the radio frequency signal RX 1-2-1 The third antenna panel is used to receive the radio frequency signal RX 1-3-1 In this way, the communication device ensures spatial isolation between the first antenna panel that sends radio frequency signals and the second antenna panel and the third antenna panel that receive radio frequency signals without sacrificing antenna panel size, thereby maintaining downlink coverage.

[0023] In one possible design, the radio frequency signal TX 1-1-1 The radio frequency signal RX belongs to the first sector. 1-2-1 The radio frequency signal RX belongs to the second sector. 1-3-1The radio frequency signal belongs to the third sector. The first sector, the second sector and the third sector are different from each other.

[0025] In one possible design, the third antenna panel is further configured to transmit a radio frequency signal TX at the first antenna panel in a second time unit. 1-1-2 In the case of 1-3-2 And does not receive RF signal RX 1-3-2 .

[0026] Wherein, the radio frequency signal TX 1-1-2 The radio frequency signal TX belongs to the first sector. 1-3-2 and the RF signal RX 1-3-2 The second time unit belongs to a non-SBFD downlink time unit.

[0027] That is, in the second time unit, the first antenna panel sends the radio frequency signal TX 1-1-2 , the third antenna panel neither sends nor receives radio frequency signals. It can be seen that the third antenna panel does not have a transmitting function. In this way, the communication device does not need to connect a transmitting channel to the antenna subarray on the third antenna panel, thereby making the communication device lightweight and helping to reduce the cost of the communication device.

[0028] In one possible design, the third antenna panel is further configured to receive a radio frequency signal RX at a third time unit when the first antenna panel receives the radio frequency signal RX at a third time unit. 1-1-3 In the case of receiving a radio frequency signal RX at the third time unit 1-3-3 .

[0029] Among them, the radio frequency signal RX 1-1-3 The radio frequency signal RX belongs to the first sector. 1-3-3 The radio frequency signal belongs to the third sector. The third time unit belongs to a non-SBFD uplink time unit.

[0030] That is, in the third time unit, the first antenna panel receives the radio frequency signal RX 1-1-3It can be seen that the first antenna panel has a transceiver function. In this way, the communication device can use the reciprocity of transceiver to set parameters. For example, based on the parameters when the first antenna panel sends the RF signal, the parameters when the first antenna panel and the third antenna panel receive the RF signal are set, thereby improving the system communication performance.

[0031] In addition, during the third time unit, the third antenna panel receives the radio frequency signal RX 1-3-3 , which helps to improve the system's uplink coverage.

[0032] In a second aspect, a system is provided, the system comprising: a first communication device and a second communication device.

The first sector, the second sector and the third sector are different from each other.

[0037] Thus, on the one hand, the first communication device does not add a wind resistance expansion antenna panel. Similarly, since the fourth antenna panel is adjacent to the fifth antenna panel, and the third angle between the fourth antenna panel and the fifth antenna panel is less than 90 degrees, the second communication device does not add a wind resistance expansion antenna panel.

[0038] On the other hand, the first communication device ensures the spatial isolation between the first antenna panel for sending radio frequency signals and the second antenna panel for receiving radio frequency signals without sacrificing the size of the antenna panel, thereby maintaining downlink coverage. Similarly, since the fourth antenna panel is used to send the radio frequency signal TX in the first time unit, 2-4-1 The fifth antenna panel is used to receive the radio frequency signal RX at the first time unit. 2-5-1 Therefore, the second communication device ensures the spatial isolation between the fourth antenna panel for sending radio frequency signals and the fifth antenna panel for receiving radio frequency signals without sacrificing the size of the antenna panels, thereby maintaining downlink coverage.

[0039] On the other hand, since the second antenna panel is parallel to the fourth antenna panel, the radio frequency signal RX received by the second antenna panel in the first time unit is 1-2-1 , and the radio frequency signal TX sent by the fourth antenna panel 2-4-1 , belonging to the same sector, so that the system can achieve duplex communication on the second sector and maintain downlink coverage.

[0112] According to a fourth aspect, a system is provided, comprising: a first communication device and a second communication device.

[0113] The first communication device includes a first antenna panel, a second antenna panel and a third antenna panel.

For example, in an ORAN system, CU may also be referred to as O-CU (open CU), DU may also be referred to as O-DU, and RU may also be referred to as 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.

For ease of description, network device is used as the abbreviation of wireless access network device, and base station is used as an example of wireless access network device.

[0391] Optionally, the terminal device accesses the core network through a network device. The terminal device includes a device that provides voice and / or data connectivity to the user, specifically, a device that provides voice to the user, or a device that provides data connectivity to the user, or a device that provides voice and data connectivity to the user. For example, it may include a handheld device with a wireless connection function, or a processing device connected to a wireless modem.

It also includes limited devices, such as devices with low power consumption, or devices with limited storage capacity, or devices with limited computing power, etc. For example, it includes information sensing devices such as barcodes, radio frequency identification (RFID), sensors, global positioning systems (GPS), laser scanners, etc.

[0392] 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 (OBU).

[0393] In the embodiment of the present application, the terminal device may also include a relay. Alternatively, it can be understood that anything that can communicate data with the base station can be regarded as a terminal device.

[0394] In the embodiment of the present application, the device for realizing the function of the terminal device may be a terminal device, or a device capable of supporting the terminal device to realize the function, such as a chip system, which may be installed in the terminal device. In the embodiment of the present application, the chip system may be composed of a chip, or may include a chip and other discrete devices. In the technical solution provided in the embodiment of the present application, the device for realizing the function of the terminal is a terminal device as an example for introduction.

[0395] It should be understood that the network equipment and terminal equipment can be fixed or movable. The network equipment and terminal equipment can be deployed on land, including indoors or outdoors, handheld or vehicle-mounted; they can also be deployed on the water surface; they can also be deployed on aircraft, balloons and artificial satellites in the air. The embodiments of the present application do not limit the application scenarios of the network equipment and terminal equipment.

[0396] 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, 110a and 120i communicate through the wireless air interface protocol. Of course, 110a and 120i can also communicate through the interface protocol between base stations. At this time, 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 may be referred to as communication devices having 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, a unit, a circuit, an antenna or a chip of a device, such as a CU or a DU. The circuit may include a radio frequency circuit. Furthermore, the circuit may further include other circuits. The communication device can also be a device, such as a terminal device (also referred to as a user device) or a network device (such as a base station).

[0397] Network devices and terminal devices, network devices and network devices, and terminal devices and terminal devices may communicate through authorized spectrum, unauthorized spectrum, or both; may 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 communication.

[0398] 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 including the network device function. The control subsystem including the network device function 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 including the terminal device function.

[0399] 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 service cell of the terminal device. When the terminal device communicates with the service cell, it will also be interfered by signals from neighboring cells.

[0400] 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.

[0401] In order to facilitate understanding of the embodiments of the present application, the following briefly describes the terms involved 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 to the present application.

[0402] 1. Wireless frame

[0403] In wireless communication systems, data is transmitted in frames. A radio frame is a period for data transmission. A radio frame usually takes a short time, for example, a radio frame is 10 milliseconds (ms).

[0404] In addition, a wireless frame may also be referred to as a frame. In this application, a frame is taken as an example for introduction.

[0405] In some embodiments, Figure 2A frame structure is shown. Figure 2 As shown in FIG. 1 , the time-frequency resources used for uplink transmission are in the box where 'U' is located. The time-frequency resources used for downlink transmission are in the box where 'D' is located. Figure 2 In the example of a frame, in the time domain, the same moment may include only downlink time units, such as the dotted box where "downlink" is located. The same moment may also include only uplink time units, such as the dotted box where "uplink" is located. The same moment may also include uplink time units and downlink time units, such as the dotted box where "sub-band duplex" is located.

[0406] 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.

[0407] 2. Subband full duplex (SBFD) time unit

[0408] 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.

[0409] For example, Figure 4 A typical SBFD time-frequency division scheme is shown. 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 in the time domain range occupied by these three time-frequency resources are called SBFD time units.

[0410] 3. Non-SBFD time unit

[0411] In the present application, the frequency resource corresponding to each symbol of all symbols included in the non-SBFD time unit is only used 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.

[0412] For example, Figure 4 The rectangular blocks filled with grid lines represent a group of time-frequency resources 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 on these time units is uplink. These time units can be called non-SBFD time slots.

[0413] 4. Antenna Panel

[0414] In the present application, an antenna panel includes multiple antennas. The antenna panel may also be referred to as an antenna surface. In the present application, the antenna panel is taken as an example for introduction.

[0415] The antenna panel can be divided into two areas in a conventional manner. At a certain moment, the antenna subarray in one area is used to send radio frequency signals, and the antenna subarray in the other area is used to receive radio frequency signals.

[0416] In the present application, there are two ways to divide the antenna panel area, namely, upper and lower separation and left and right separation. Figure 5 As shown, the left and right separation can be Figure 6 As shown. Figure 5 or Figure 6 In the example, the "transmitting antenna" indicates that the antenna subarray in the area is used to send radio frequency signals, and the "receiving antenna" indicates that the antenna subarray in the area is used to receive radio frequency signals.

[0417] However, under the traditional area division method of the antenna panel, the antenna subarray used to send radio frequency signals only occupies part of the area of ​​the antenna panel, resulting in low downlink coverage.

[0418] In view of this, the embodiments of the present application provide a communication device, a system and a signal processing method. Figure 1 A portion of the network device shown. The signal processing method can be applied to Figure 1The network device shown in the figure ensures the spatial isolation between the antenna panels for sending and receiving RF signals without increasing the wind resistance and expanding the antenna panels, while maintaining the downlink coverage without losing the size of the antenna panels.

[0419] Next, twelve embodiments (embodiments 1 to 12) are described in detail.

[0420] Embodiment 1

[0421] The embodiment of the present application provides a communication device. The communication device of the first embodiment can be recorded as a first communication device. The first communication device includes a first antenna panel and a second antenna panel. In the first embodiment, the type of the first communication device is the first type, that is, it includes two antenna panels, such as the first antenna panel and the second antenna panel.

[0422] The first antenna panel is adjacent to the second antenna panel, and a first angle between the first antenna panel and the second antenna panel is less than 90 degrees. The first antenna panel is used to send a radio frequency signal TX in a first time unit. 1-1-1 The second antenna panel is used to receive the radio frequency signal RX at the first time unit 1-2-1 The first time unit belongs to the time unit of SBFD.

[0423] by Figure 7 For example, the first communication device is a connection structure as shown in the dotted thin line ellipse. Figure 7 In the embodiment, the first antenna panel is the antenna panel 101, and the second antenna panel is the antenna panel 105. The antenna panel 101 may or may not be in contact with the antenna panel 105, and this is not limited in the present application. The first angle between the antenna panel 101 and the antenna panel 105 is less than 90 degrees, which can be understood as that the antenna panel 101 and the antenna panel 105 are not coplanar, and in the normal direction of the antenna panel 101, the area of ​​the antenna panel is not increased, that is, the wind resistance of the antenna panel is not increased.

[0424] by Figure 8 For example, the first communication device is a connection structure as shown in the dotted thin line ellipse. Figure 8 In the embodiment, the first antenna panel is the antenna panel 111, and the second antenna panel is the antenna panel 116. The antenna panel 111 may or may not be in contact with the antenna panel 116, and this is not limited in the present application. The first angle between the antenna panel 111 and the antenna panel 116 is less than 90 degrees, which can be understood as that the antenna panel 111 and the antenna panel 116 are not coplanar, and in the normal direction of the antenna panel 111, the area of ​​the antenna panel is not increased, that is, the wind resistance of the antenna panel is not increased.

[0425] It is easy to understand that in the present application, the time unit may include one of the following: radio frame, subframe, time slot, symbol, etc. Among them, radio frame, subframe, time slot, symbol, etc. can refer to the relevant technical specifications of 3GPP and will not be repeated here.

[0426] It is easy to understand that, in the present application, the first time unit belongs to the time unit of SBFD, which can be understood as a duplex time unit, such as a duplex time slot.

[0427] In this way, on the one hand, since the first antenna panel is adjacent to the second antenna panel and the first angle between the first antenna panel and the second antenna panel is less than 90 degrees, the first communication device does not add a wind resistance expansion antenna panel. On the other hand, in the same time unit (such as the first time unit), the first antenna panel is used to send the radio frequency signal TX 1-1-1 The second antenna panel is used to receive the RF signal RX 1-2-1 In this way, the first communication device ensures spatial isolation between the antenna panel for sending radio frequency signals (ie, the first antenna panel) and the antenna panel for receiving radio frequency signals (ie, the second antenna panel) without sacrificing the size of the antenna panel, thereby maintaining downlink coverage.

[0428] In some embodiments, the radio frequency signal TX 1-1-1 The RF signal belonging to the first sector, RF signal RX 1-2-1 A radio frequency signal belonging to a second sector, wherein the first sector is different from the second sector.

[0429] Exemplarily, in the first communication device:

[0430] The radio frequency signal sent by the first antenna panel in the first time unit, that is, the radio frequency signal TX 1-1-1 , the RF signal belonging to the first sector 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 panel of the first communication device in the first time unit.

[0431] The second antenna panel receives a radio frequency signal in the first time unit, that is, a radio frequency signal RX 1-2-1 , the RF signal belonging to the second sector 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 panel of the first communication device in the first time unit.

[0432] That is, in the same time unit (such as the first time unit), the radio frequency signal (such as the radio frequency signal TX 1-1-1 ) and the radio frequency signal received by the first communication device (such as the radio frequency signal RX1-2-1 ) belong to different sectors, thus laying the foundation for different communication devices to coordinate the transmission and reception of radio frequency signals in the same sector.

[0433] In some embodiments, the first antenna panel is further configured to send a radio frequency signal TX at a second time unit. 1-1-2 , RF signal TX 1-1-2 The radio frequency signal belonging to the first sector can be understood as the first antenna panel is also used to send the radio frequency signal of the first sector in the second time unit.

[0434] The second antenna panel is further used for not sending the radio frequency signal TX in the second time unit 1-2-2 And does not receive RF signal RX 1-2-2 , RF signal TX 1-2-2 and RF signal RX 1-2-2 The radio frequency signal belonging to the second sector. It can be understood that the second antenna panel is also used not to work in the second time unit. In other words, the antenna subarray on the second antenna panel is not connected to the transmission channel, thereby making the communication device lightweight and reducing the cost of the communication device.

[0435] The second time unit belongs to a non-SBFD downlink time unit, which can be understood as all time units on the same bandwidth part (BWP) being downlink time units, such as a pure transmission time slot.

[0436] Exemplarily, the radio frequency signal sent by the first antenna panel in the second time unit, that is, the radio frequency signal TX 1-1-2 , the RF signal belonging to the first sector 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 panel of the first communication device in the second time unit.

[0437] The RF signal that the second antenna panel does not receive in the second time unit can be recorded as RX 1-2-2 Among them, 'RX 1-2-2 'It can be understood that: the second antenna panel of the first communication device does not receive the radio frequency signal in the second time unit.

[0438] The RF signal not transmitted by the second antenna panel in the second time unit can be recorded as TX 1-2-2 Among them, 'TX 1-2-2 'It can be understood that: the second antenna panel of the first communication device does not send a radio frequency signal in the second time unit.

[0439] That is, in the second time unit, the first antenna panel sends the radio frequency signal TX 1-1-2, and the second antenna panel does not send or receive radio frequency signals. It can be seen that the second antenna panel does not have a transmitting function. In this way, the first communication device does not need to connect a transmitting channel to the antenna subarray on the second antenna panel, thereby making the communication device lightweight and helping to reduce the cost of the communication device.

[0440] In some embodiments, the first antenna panel is further configured to receive a radio frequency signal RX at a third time unit. 1-1-3 , RF signal RX 1-1-3 The radio frequency signal belonging to the first sector can be understood as the first antenna panel is also used to receive the radio frequency signal of the first sector in the third time unit.

[0441] The second antenna panel is further used to receive a radio frequency signal RX at a third time unit. 1-2-3 , RF signal RX 1-2-3 The radio frequency signal belonging to the second sector can be understood as the second antenna panel is also used to receive the radio frequency signal of the second sector in the third time unit.

[0442] The third time unit belongs to a non-SBFD uplink time unit, which can be understood as all time units on the same BWP being uplink time units, such as pure receiving time slots.

[0443] Exemplarily, the radio frequency signal received by the first antenna panel in the third time unit, that is, the radio frequency signal RX 1-1-3 , the RF signal belonging to the first sector can be recorded as TX 1-1-3 Among them, 'TX 1-1-3 'It can be understood as: the radio frequency signal received by the first antenna panel of the first communication device in the third time unit.

[0444] The radio frequency signal received by the second antenna panel in the third time unit, that is, the radio frequency signal RX 1-2-3 , the RF signal belonging to the second sector 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 panel of the first communication device in the third time unit.

[0445] That is, in the third time unit, the first antenna panel receives the radio frequency signal RX 1-1-3 It can be seen that the first antenna panel has a transceiver function. In this way, the first communication device can use the reciprocity of transceiver to set parameters, for example, based on the parameters when the first antenna panel sends the RF signal, set the parameters when the first antenna panel and the second antenna panel receive the RF signal, thereby improving the system communication performance.

[0446] In addition, at the third time unit, the second antenna panel receives the radio frequency signal RX 1-2-3, which helps to improve the system's uplink coverage.

[0447] Embodiment 2

[0448] The embodiment of the present application provides another communication device. The communication device of the second embodiment can be recorded as a first communication device. The first communication device includes a first antenna panel, a second antenna panel, and a third antenna panel. In the second embodiment, the type of the first communication device is the second type, that is, it includes three antenna panels, such as the first antenna panel, the second antenna panel, and the third antenna panel.

[0449] The first antenna panel and the second antenna panel can be found in the introduction of the first embodiment and will not be described in detail.

[0450] The second antenna panel and the third antenna panel are both located on the same side of the first antenna panel, the first antenna panel is adjacent to the third antenna panel, and the second angle between the first antenna panel and the third antenna panel is less than 90 degrees. The third antenna panel is used to receive the radio frequency signal RX at the first time unit 1-3-1 .

[0451] The first time unit belongs to the time unit of SBFD, and reference may be made to the introduction of the first embodiment, which will not be described in detail.

[0452] by Fig. 9 For example, the first communication device is a connection structure as shown in the dotted thin line ellipse. Fig. 9 In the figure, the first antenna panel is antenna panel 101 , the second antenna panel is antenna panel 105 , and the third antenna panel is antenna panel 104 .

[0453] The antenna panel 101 may or may not be in contact with the antenna panel 105, which is not limited in this application. The first angle between the antenna panel 101 and the antenna panel 105 is less than 90 degrees, which can be understood as that the antenna panel 101 and the antenna panel 105 are not coplanar, and in the normal direction of the antenna panel 101, the area of ​​the antenna panel is not increased, that is, the wind resistance of the antenna panel is not increased.

[0454] The antenna panel 101 may or may not be in contact with the antenna panel 104, which is not limited in this application. The second angle between the antenna panel 101 and the antenna panel 104 is less than 90 degrees, which can be understood as that the antenna panel 101 and the antenna panel 104 are not coplanar, and in the normal direction of the antenna panel 101, the area of ​​the antenna panel is not increased, that is, the wind resistance of the antenna panel is not increased.

[0455] It is easy to understand that in the present application, the first angle and the second angle may be the same or different, and the present application does not limit this.

[0456] In this way, on the one hand, since the first antenna panel is adjacent to the second antenna panel and the first angle between the first antenna panel and the second antenna panel is less than 90 degrees, and the first antenna panel is adjacent to the third antenna panel and the second angle between the first antenna panel and the third antenna panel is less than 90 degrees, when the second antenna panel and the third antenna panel are located on the same side of the first antenna panel, the first communication device does not increase the wind resistance to expand the antenna panel.

[0457] On the other hand, in the same time unit (such as the first time unit), the first antenna panel is used to send the radio frequency signal TX 1-1-1 The second antenna panel is used to receive the RF signal RX 1-2-1 The third antenna panel is used to receive the RF signal RX 1-3-1 In this way, the first communication device ensures the spatial isolation between the antenna panel for sending radio frequency signals (i.e., the first antenna panel) and the antenna panel for receiving radio frequency signals (i.e., the second antenna panel and the third antenna panel) without sacrificing the size of the antenna panel, thereby maintaining downlink coverage.

[0463] That is, in the same time unit (such as the first time unit), the radio frequency signal (such as the radio frequency signal TX 1-1-1 ) and the radio frequency signal received by the first communication device (such as the radio frequency signal RX 1-2-1 , RF signal RX 1-3-1 ) belong to different sectors, thus laying the foundation for different communication devices to coordinate the transmission and reception of radio frequency signals in the same sector.

[0464] In some embodiments, the first antenna panel is further configured to send a radio frequency signal TX at a second time unit. 1-1-2 , RF signal TX 1-1-2 The radio frequency signal belonging to the first sector can be understood as the first antenna panel is also used to send the radio frequency signal of the first sector in the second time unit.

[0465] The second antenna panel is further used for not sending the radio frequency signal TX in the second time unit 1-2-2 And does not receive RF signal RX 1-2-2 , RF signal TX 1-2-2 and RF signal RX 1-2-2 The radio frequency signal belonging to the second sector. It can be understood that the second antenna panel is also used not to work in the second time unit. In other words, the antenna subarray on the second antenna panel is not connected to the transmission channel, thereby making the first communication device lightweight and reducing the cost of the first communication device.

[0466] The third antenna panel is also used to send a radio frequency signal TX on the first antenna panel at the second time unit 1-1-2 In the case of 1-3-2 And does not receive RF signal RX 1-3-2 Among them, the RF signal TX 1-3-2 and RF signal RX 1-3-2 The radio frequency signal belongs to the third sector. It can be understood that the third antenna panel is also used not to work in the second time unit. In other words, the antenna subarray on the third antenna panel is not connected to the transmission channel, thereby making the first communication device lightweight and reducing the cost of the first communication device.

[0467] The second time unit is a non-SBFD downlink time unit, and reference may be made to the introduction of the first embodiment, which will not be described in detail.

[0468] Exemplarily, in the first communication device:

[0472] The RF signal that the third antenna panel does not receive in the second time unit can be recorded as RX 1-3-2 Among them, 'RX 1-3-2 It can be understood that: the radio frequency signal that the third antenna panel of the first communication device does not receive in the second time unit belongs to the radio frequency signal of the third sector.

[0473] The RF signal not sent by the third antenna panel in the second time unit can be recorded as TX 1-3-2 Among them, 'TX 1-3-2 It can be understood that the radio frequency signal not sent by the third antenna panel of the first communication device in the second time unit belongs to the radio frequency signal of the third sector.

[0474] That is, in the second time unit, the first antenna panel sends the radio frequency signal TX 1-1-2 , the second antenna panel and the third antenna panel do not send or receive radio frequency signals. It can be seen that the second antenna panel and the third antenna panel do not have a transmitting function. In this way, the first communication device does not need to connect the transmitting channel for the antenna subarrays on the second antenna panel and the third antenna panel, thereby making the communication device lightweight and helping to reduce the cost of the communication device.

[0475] In some embodiments, the first antenna panel is further configured to receive a radio frequency signal RX at a third time unit. 1-1-3 , RF signal RX 1-1-3 The radio frequency signal belonging to the first sector can be understood as the first antenna panel is also used to receive the radio frequency signal of the first sector in the third time unit.

[0476] The second antenna panel is further used to receive a radio frequency signal RX at a third time unit. 1-2-3 , RF signal RX 1-2-3 The radio frequency signal belonging to the second sector can be understood as the second antenna panel is also used to receive the radio frequency signal of the second sector in the third time unit.

[0477] The third antenna panel is further used to receive the radio frequency signal RX at the first antenna panel in the third time unit. 1-1-3 In the case of receiving the radio frequency signal RX at the third time unit 1-3-3 Among them, the RF signal RX 1-3-3 The radio frequency signal belonging to the third sector can be understood as the third antenna panel is also used to receive the radio frequency signal of the third sector in the third time unit.

[0483] That is, in the third time unit, the first antenna panel receives the radio frequency signal RX 1-1-3It can be seen that the first antenna panel has a transceiver function. In this way, the first communication device can use the reciprocity of transceiver to set parameters. For example, based on the parameters when the first antenna panel sends the RF signal, the parameters when the first antenna panel, the second antenna panel and the third antenna panel receive the RF signal are set, thereby improving the system communication performance.

[0484] In addition, at the third time unit, the second antenna panel receives the radio frequency signal RX 1-2-3 , the third antenna panel receives the RF signal RX 1-3-3 , which helps to improve the system's uplink coverage.

[0485] Embodiment 3

[0486] The embodiment of the present application provides a system. The system of the third embodiment can be recorded as a first system. The first system includes a first communication device and a second communication device.

[0487] The first communication device includes a first antenna panel and a second antenna panel. It can be understood that the type of the first communication device is the first type. In the third embodiment, the first communication device can refer to the introduction of the first embodiment, and will not be described in detail.

[0488] The second communication device includes a fourth antenna panel and a fifth antenna panel. It can be understood that the type of the second communication device is the first type.

[0489] In the second communication device, the fourth antenna panel is adjacent to the fifth antenna panel, and a third angle between the fourth antenna panel and the fifth antenna panel is less than 90 degrees. The fourth antenna panel is used to send a radio frequency signal TX in the first time unit. 2-4-1 The fifth antenna panel is used to receive the radio frequency signal RX at the first time unit. 2-5-1 .

[0490] by Figure 7 For example, the second communication device is connected in a structure as shown in a solid thin line oval. Figure 7 In the embodiment, the fourth antenna panel is the antenna panel 102, and the fifth antenna panel is the antenna panel 107. The antenna panel 102 may or may not be in contact with the antenna panel 107, and this is not limited in the present application. The third angle between the antenna panel 102 and the antenna panel 107 is less than 90 degrees, which can be understood as that the antenna panel 102 and the antenna panel 107 are not coplanar, and in the normal direction of the antenna panel 102, the area of ​​the antenna panel is not increased, that is, the wind resistance of the antenna panel is not increased.

[0491] by Figure 8 For example, the second communication device is connected in a structure as shown in a solid thin line oval. Figure 8In the embodiment, the fourth antenna panel is the antenna panel 113, and the fifth antenna panel is the antenna panel 112. The antenna panel 113 may or may not be in contact with the antenna panel 112, and this is not limited in the present application. The third angle between the antenna panel 113 and the antenna panel 112 is less than 90 degrees, which can be understood as that the antenna panel 113 is not coplanar with the antenna panel 112, and in the normal direction of the antenna panel 113, the area of ​​the antenna panel is not increased, that is, the wind resistance of the antenna panel is not increased.

[0492] Exemplarily, in the second communication device:

[0493] The radio frequency signal sent by the fourth antenna panel in the first time unit, that is, the radio frequency signal TX 2-4-1 , the RF signal belonging to the second sector can be recorded as TX 2-4-1 Among them, 'TX 2-4-1 'It can be understood as: the radio frequency signal sent by the fourth antenna panel of the second communication device in the first time unit.

[0494] The radio frequency signal received by the fifth antenna panel in the first time unit, that is, the radio frequency signal RX 2-5-1 , the RF signal belonging to the third sector can be recorded as RX 2-5-1 Among them, 'RX 2-5-1 'It can be understood as: the radio frequency signal received by the fifth antenna panel of the second communication device in the first time unit.

[0495] The positional relationship between antenna panels of different communication devices is as follows:

[0496] The second antenna panel is parallel to the fourth antenna panel. 1-2-1 With TX 2-4-1 The RF signal RX belongs to the same sector. In other words, the RF signal RX 1-2-1 The radio frequency signal belonging to the second sector, radio frequency signal TX 2-4-1 The radio frequency signal belongs to the second sector.

Similarly, since the fourth antenna panel is adjacent to the fifth antenna panel and the third angle between the fourth antenna panel and the fifth antenna panel is less than 90 degrees, the second communication device does not add a wind resistance expansion antenna panel.

[0500] On the other hand, since the first antenna panel is used to send the radio frequency signal TX at the first time unit 1-1-1 The second antenna panel is used to receive the radio frequency signal RX on the first time unit 1-2-1 Therefore, the first communication device ensures the spatial isolation between the antenna panel for sending radio frequency signals (i.e., the first antenna panel) and the antenna panel for receiving radio frequency signals (i.e., the second antenna panel) without sacrificing the size of the antenna panel, thereby maintaining downlink coverage. Similarly, since the fourth antenna panel is used to send the radio frequency signal TX at the first time unit, 2-4-1 The fifth antenna panel is used to receive the radio frequency signal RX at the first time unit 2-5-1 Therefore, the second communication device ensures the spatial isolation between the antenna panel for sending radio frequency signals (ie, the fourth antenna panel) and the antenna panel for receiving radio frequency signals (ie, the fifth antenna panel) without sacrificing the size of the antenna panel, thereby maintaining downlink coverage.

It can be understood that the radio frequency signals sent and received by the first communication device and the radio frequency signals sent and received by the second communication device are processed by the same baseband device.

It can be understood that the fifth antenna panel is also used not to work in the second time unit. In other words, the antenna subarray on the fifth antenna panel is not connected to the transmission channel, thereby making the communication device lightweight and reducing the cost of the communication device.

[0517] That is, in the second time unit, the first antenna panel sends the radio frequency signal TX 1-1-2 , and the second antenna panel does not send or receive radio frequency signals. It can be seen that the second antenna panel does not have a transmitting function. In this way, the first communication device does not need to connect a transmitting channel to the antenna subarray on the second antenna panel, thereby making the communication device lightweight and helping to reduce the cost of the communication device.

[0518] Similarly, in the second time unit, the fourth antenna panel sends the radio frequency signal of the second sector, and the fifth antenna panel does not send and does not receive the radio frequency signal.
