Description

TECHNICAL FIELD

[0001] Embodiments of the present application relate to the field of communication, and more particularly, to a communication method and a communication apparatus. BACKGROUND

[0002] Signals are transmitted through electromagnetic waves in the air, and there is power loss in the transmission process, which affects the coverage of communication. In a communication system, the base station side often improves the coverage through multi-antenna technology. That is, the coverage is improved through beamforming. In multi-antenna technology, in order to improve the performance of communication, the terminal device and the network device need to obtain the optimal beam pair between them through beam training before transmitting data, and then perform data transmission through the optimal beam pair determined by the beam training. In this way, the benefits brought by multi-antenna beamforming can be fully utilized. However, in the current beam training process, when the terminal device is in a single-panel working state, only one beam can be transmitted at the same time for beam training. For multiple beams of the terminal device and multiple beams of the network device, the terminal device determines the optimal beam pair through training in sequence or periodically, and the training overhead is large. SUMMARY

[0003] Embodiments of the present application provide a communication method and a communication apparatus, which can reduce the overhead of beam training.

[0004] In a first aspect, a communication method is provided, which can be executed by a terminal device, or can also be executed by a component (such as a chip or a circuit) of the terminal device, and no limitation is made in this regard. For ease of description, the following is described by way of example with the terminal device.

[0006] In the technical solution, the terminal device reports first indication information, which indicates that the terminal device can support multi-panel operation, that is, the terminal device can support at least two panels to work simultaneously at the same time. Therefore, when performing beam training, the terminal device can complete the training of at least two beams at one time. In this way, the terminal device and the network device can reduce the number of beam transmission, reception and / or detection when performing beam training, thereby reducing the overhead of beam training between the terminal device and the network device, improving system performance, and reducing the energy consumption of the network device and the terminal device. In addition, the network device can also obtain the corresponding relationship of each parameter when the terminal device is in different working states according to the first indication information, which is beneficial to the network device to perform data scheduling according to the corresponding relationship, better adapt to the communication capability of the terminal device, and thereby improve the communication performance between the network device and the terminal device.

Figure 1As shown, the communication system includes a radio access network 100 and a core network 200. Optionally, the communication system 1000 can also include an Internet 300. The radio access network 100 can include at least one radio access network device (e.g., 110a and 110b in FIG. 1) and at least one terminal (e.g., 120a-120j in FIG. 1). The terminal is connected to the radio access network device in a wireless manner. The radio access network device is connected to the core network in a wireless or wired manner. The core network device and the radio access network device can be independent and different physical devices. Alternatively, the core network device and the radio access network device can be integrated in the same physical device. Alternatively, the core network device and the radio access network device can be integrated in the same physical device. The terminal and the terminal, and the radio access network device and the radio access network device can be connected to each other in a wired or wireless manner. Figure 1 Figure 1 Figure 1 Figure 1

[0059] ​​​​The radio access network device can be a base station, an evolved NodeB (eNodeB), a transmission reception point (TRP), a next generation NodeB (gNB) in a 5th generation (5G) mobile communication system, a next generation NodeB in a 6th generation (6G) mobile communication system, a base station in a future mobile communication system, or an access node in a WiFi system, etc. The radio access network device can also be a module or unit that performs part of the functions of a base station, for example, it can be a central unit (CU) or a distributed unit (DU). The CU performs the functions of the radio resource control protocol and the packet data convergence protocol (PDCP) of the base station, and can also perform the function of the service data adaptation protocol (SDAP). The DU performs the functions of the radio link control layer and the medium access control (MAC) layer of the base station, and can also perform part or all of the functions of the physical layer. For specific descriptions of the above-mentioned protocol layers, reference can be made to the relevant technical specifications of the 3rd generation partnership project (3GPP). The radio access network device can be a macro base station (such as 110a in FIG. 1), a micro base station or an indoor station (such as 110b in FIG. 1), a relay node or a donor node, etc. The embodiments of the present application do not limit the specific technology and specific device form adopted by the radio access network device. For ease of description, the following describes the base station as an example of the radio access network device. Figure 1 Figure 1

[0060] ​​A terminal can also be called a terminal device, user equipment (UE), mobile station, mobile terminal, etc. Terminals can be widely used in various scenarios, such as device-to-device (D2D), vehicle-to-everything (V2X) communication, machine-type communication (MTC), Internet of Things (IoT), virtual reality, augmented reality, industrial control, autonomous driving, telemedicine, smart grids, smart furniture, smart offices, smart wearables, smart transportation, smart cities, etc. Terminals can be mobile phones, tablets, computers with wireless transceiver capabilities, wearable devices, vehicles, drones, helicopters, airplanes, ships, robots, robotic arms, smart home devices, etc. The embodiments of this application do not limit the specific technologies or device forms used in the terminals.

[0061] Base stations and terminals can be fixed or mobile. They can be deployed on land, including indoors or outdoors, handheld or vehicle-mounted; they can also be deployed on water; and they can be deployed on aircraft, balloons, and satellites. The embodiments of this application do not limit the application scenarios of the base stations and terminals.

[0062] The roles of base stations and terminals can be relative, for example, Figure 1 The helicopter or drone 120i can be configured as a mobile base station. For terminals 120j accessing the wireless access network 100 via 120i, terminal 120i is a base station; however, for base station 110a, 120i is a terminal, meaning that 110a and 120i communicate via a wireless air interface protocol. Of course, 110a and 120i can also communicate via a base station-to-base station interface protocol; in this case, 120i is also a base station relative to 110a. Therefore, both base stations and terminals can be collectively referred to as communication devices. Figure 1 The 110a and 110b in the text can be referred to as communication devices with base station functions. Figure 1 The 120a-120j in the text can be referred to as communication devices with terminal functions.

[0063] Communication between base stations and terminals, between base stations, and between terminals can be conducted using licensed spectrum, unlicensed spectrum, or both simultaneously. Communication can be conducted using spectrum below 6 GHz, spectrum above 6 GHz, or both simultaneously. The embodiments of this application do not limit the spectrum resources used for wireless communication.

[0064] In the embodiments of the present application, the functions of the base station can also be performed by a module (such as a chip) in the base station, or by a control subsystem containing the functions of the base station. The control subsystem containing the functions of the base station herein can be a control center in the above-mentioned application scenarios such as smart grid, industrial control, intelligent transportation, and smart city. The functions of the terminal can also be performed by a module (such as a chip or a modem) in the terminal, or by a device containing the functions of the terminal.

[0065] In the present application, the base station sends a downlink signal or downlink information to the terminal, and the downlink information is carried on a downlink channel; the terminal sends an uplink signal or uplink information to the base station, and the uplink information is carried on an uplink channel. In order to communicate with the base station, the terminal needs to establish a wireless connection with a cell controlled by the base station. The cell with which the terminal establishes a wireless connection is called the service cell of the terminal. When the terminal communicates with the service cell, it will also be interfered by signals from neighboring cells.

[0066] According to whether the specification uses optional: In the embodiments of the present application, the time domain symbol can be an orthogonal frequency division multiplexing (OFDM) symbol, or a Discrete Fourier Transform-spread-OFDM (DFT-s-OFDM) symbol. If not specified, the symbol in the embodiments of the present application refers to a time domain symbol.

[0067] According to whether the specification uses optional: It can be understood that, in the embodiments of the present application, the downlink data channel can be a physical downlink shared channel (PDSCH), the downlink control channel can be a physical downlink control channel (PDCCH), and the uplink data channel can be a physical uplink shared channel (PUSCH). It should be understood that PDSCH, PDCCH and PUSCH are only used as examples, and in different systems and different scenarios, data channels and control channels can have different names, and the embodiments of the present application do not limit this.

[0068] In order to facilitate understanding of the technical solutions of the present application, first, the concepts and related processes involved in the present application are introduced.

[0069] 1. Panel: A panel is composed of antennas, therefore it can also be called an antenna panel. Since there are two interpretations of antenna: one is the logical concept of an antenna, and the other is a physical antenna entity, the panel in this application can be composed of logical antennas, in which case it can also be called a logical panel. Alternatively, the panel in this application can be composed of physical antennas, in which case it can be called a physical panel. A panel includes multiple antenna elements. When a panel is in operation, the beams formed by the antenna elements of that panel can transmit signals. The beams formed by the antenna elements of different panels can be adjusted independently. A terminal device can include multiple panels. At any given time, only one panel among the multiple panels included in the terminal device can be operational, i.e., the terminal device is in a single-panel operation state. Correspondingly, at any given time, at least two panels among the multiple panels included in the terminal device can be operational, i.e., the terminal device is in a multi-panel operation state. It should be understood that the terminal device in this application includes multiple panels. When the panel is a physical panel, the terminal device can be considered to include multiple panels; when the panel is a logical panel, the terminal device can be considered to correspond to multiple panels. The following explanation uses the example of a terminal device including multiple panels.

[0070] 2. Beam training: such as Figure 2 As shown, the purpose of beam training is to find the slash-filled fine beams (i.e., the optimal fine beam pairs) among the many possible beams corresponding to network devices and terminal devices. Figure 2 In this method, network devices use slash-filled beams to transmit or receive signals, and corresponding terminal devices also use slash-filled beams to receive or transmit signals. This maximizes signal strength and achieves optimal communication performance. One technique divides beam training into three steps, which are described in detail below with reference to Figure 3.

[0071] Step 1: Wide-beam training of network devices and terminal devices.

[0072] In this step, such as Figure 3A As shown, the network device transmits a series of wide beams, for example, N1 wide beams. Correspondingly, the terminal device receives a series of wide beams, assuming M1 wide beams. The terminal device can detect the optimal wide beam pair among N1*M1 beam pairs, thus completing the training of the wide beam pair. The obtained optimal wide beam pair is denoted as (beam #1, beam #2), where beam #1 represents the optimal wide beam obtained by the network device, and beam #2 represents the optimal wide beam obtained by the terminal device.

[0073] Step 2: Beamforming training for network devices.

[0074] Based on step 1, such as Figure 3BAs shown in FIG. 3, the network device sends a series of fine beams based on the wide beam #1, for example, N2 fine beams, and the terminal device detects the optimal fine beam of the network device, recorded as beam #3, to complete the fine beam training of the network device.

[0075] Step 3: Fine beam training of the terminal device.

[0076] As shown in FIG. 4, the network device fixes the fine beam trained by the network device, and the terminal device finds the optimal fine beam of the terminal device. Specifically, the terminal device sends a series of fine beams based on the wide beam #2, for example, M2 fine beams. The network device detects the optimal fine beam of the terminal device, recorded as beam #4, to complete the fine beam training of the terminal device. Figure 3C

[0077] Through the above three steps, the network device and the terminal device obtain the optimal fine beam pair (beam #3, beam #4), and then data transmission can be performed using the optimal fine beam pair. It should be understood that steps 1 to 3 are only used to illustrate the specific method of beam training, and do not limit the specific order of training. For example, the optimal wide beam pair can be obtained by performing step 1 first, and then the fine beam training of the terminal device is performed, and then the fine beam training of the network device is performed according to the fine beam training completed by the terminal.

[0078] It should be noted that in steps 1 and 3, the terminal device works in a single panel state, and can only send one beam for beam training at the same time. For multiple beams of the terminal device and multiple beams of the network device, the terminal device determines the optimal beam pair according to the order or periodic training, which will result in a large beam training overhead, a decrease in system capacity, and an increase in energy consumption of the network device and the terminal device.

[0079] Therefore, the present application proposes a method to effectively solve the above technical problems. The method proposed by the present application will be described in detail below.

[0080] As shown in FIG. 5, Figure 4 Figure 4 is a schematic flow chart of a communication method proposed by the present application. Figure 4 The method shown in FIG. 5 can include the following operations.

[0081] S401, the terminal device generates first indication information.

[0082] ​​The first indication information is used to indicate a corresponding relationship of at least one parameter in a single-panel working state and a multi-panel working state of the terminal device, wherein the at least one parameter includes at least one of a first parameter, a second parameter or a third parameter, the terminal device includes a plurality of panels, the plurality of panels include a first panel, the first parameter is a number of signal transmission channels corresponding to the first panel, the second parameter is a power of a received signal on each channel corresponding to the first panel, and the third parameter is a power of a received signal of the first panel.

[0083] Optionally, the first indication information can indicate specific values of the at least one parameter in the single-panel working state and the multi-panel working state of the terminal device, and / or a size relationship of the at least one parameter in the single-panel working state and the multi-panel working state of the terminal device. The following will be described in detail.

[0084] The content indicated by the first indication information can also be described as: the first information is used to indicate that when the terminal device changes from the single-panel working state to the multi-panel working state, or when the terminal device changes from the multi-panel working state to the single-panel working state, a value of one or more of the first parameter, the second parameter and the third parameter corresponding to the first panel increases, decreases or remains unchanged.

[0085] As an example, the first information can be used to indicate that when the terminal device changes from the single-panel working state to the multi-panel working state, or when the terminal device changes from the multi-panel working state to the single-panel working state, a value of one or more of the first parameter, the second parameter and the third parameter corresponding to the first panel increases by a multiple P, decreases by a multiple Q or remains unchanged. Wherein, P and Q are greater than 0. It should also be understood that the first parameter is the number of signal transmission channels corresponding to the first panel, specifically, the maximum number of channels that can be supported when the terminal device uses the first panel for signal transmission. Exemplarily, the channel can refer to an antenna port, or a digital channel, or an analog channel, which is not limited in the present application.

[0086] When the terminal device is in the single-panel working state, the first panel is the only working panel in the single-panel state.

[0087] When the terminal device is in the multi-panel working state, the first panel is one of the panels or a plurality of panels working in the multi-panel working state of the terminal device, or each of the panels working in the multi-panel working state of the terminal device.

[0088] When the first panel is each of the plurality of working panels, that is, each of the plurality of simultaneously working panels satisfies the corresponding relationship indicated by the first indication information.

[0089] When the first panel is one or more working panels in the plurality of panels, that is, only one or more panels in the plurality of panels working simultaneously satisfy the corresponding relationship indicated by the first indication information, in this mode, in addition to sending the first indication information to the network device, the terminal device can also indicate the first panel through the first indication information or other information. For example, the terminal device includes three panels, panel 1, panel 2 and panel 3, when the terminal device is in a multi-panel working state, panel 1 and panel 2 work simultaneously, and panel 1 satisfies the corresponding relationship indicated by the first indication information, the terminal device can also indicate panel 1 to the network device through the first indication information or other information.

[0090] In practice, different terminal devices can use different antenna structures. The following application gives the corresponding relationship of the first parameter, the second parameter and the third parameter in the case of single-panel and multi-panel working of three different antenna structures.

[0091] (1) The terminal device uses the first antenna structure: the number of panels is X0 (X0≥2), the first antenna structure satisfies the following characteristics: when the terminal device is in a multi-panel working state, the number of channels corresponding to at least one panel in the plurality of working panels is less than the number of channels corresponding to the working panel when the terminal device is in a single-panel working state. Wherein, the corresponding relationship of the first parameter, the second parameter and the third parameter of the terminal device in the case of single-panel and multi-panel working is as follows:

[0092] ① In the single-panel working state, the value of the first parameter is Y0, the value of the second parameter is P0, and the value of the third parameter is P0*Y0, wherein X0, Y0 are positive integers, and P0>0.

[0093] ② In the multi-panel working state, the value of the first parameter is Z0, Z0 is less than Y0, the value of the second parameter is P0, and the value of the third parameter is Z0*Y0, wherein Z0 is a positive integer.

[0094] (2) The terminal device uses the second antenna structure: the number of panels is X1 (X1≥2), the second antenna structure satisfies the following characteristics: when the terminal device is in a multi-panel working state, the number of channels corresponding to each panel in the plurality of working panels is not less than the number of channels corresponding to the working panel when the terminal device is in a single-panel working state. Wherein, the corresponding relationship of the first parameter, the second parameter and the third parameter of the terminal device in the case of single-panel and multi-panel working is as follows:

[0095] ① In the single-panel working state, the value of the first parameter is Y1, the value of the second parameter is P1, and the value of the third parameter is P1*Y1, wherein X1, Y1 are positive integers, and P1>0.

[0096] ② In the multi-panel working state, the value of the first parameter is Z1, Z1 is greater than or equal to Y1, the value of the second parameter is P1, and the value of the third parameter is Z1*Y1, wherein Z1 is a positive integer.

[0097] (3) The terminal device adopts a third antenna structure: the number of panels is X2 (X2≥2), and the third antenna structure satisfies the following characteristics: when the terminal device is in the multi-panel working state, the number of channels corresponding to at least one panel in the multiple working panels is not greater than the number of channels corresponding to the working panel when the terminal device is in the single-panel working state, and the power of the received signal on at least one channel of the working panel with a reduced number of channels becomes larger in the multi-panel working state. Wherein, the corresponding relationship among the first parameter, the second parameter and the third parameter of the terminal device in the single-panel and multi-panel working states is as follows:

[0098] ① In the single-panel working state, the value of the first parameter is Y2, the value of the second parameter is P2, and the value of the third parameter is P2*Y2, wherein X2 and Y2 are positive integers, and P2>0.

[0099] ② In the multi-panel working state, the value of the first parameter is Z2, Z2 is less than or equal to Y2, the value of the second parameter is Q2, Q2 is greater than or equal to P2, the value of the third parameter is Z2*Y2, and P2*Y2 is equal to Z2*Y2, wherein Z2 is a positive integer.

[0100] In summary, when the terminal device adopts the first antenna structure to the third antenna structure, the corresponding relationship among the first parameter, the second parameter and the third parameter in the single-panel and multi-panel working states is shown in Table 1.

[0101] Table 1

[0102]

[0103] Optionally, before the terminal device sends the first indication information, the terminal device and the network device can also pre-configure the corresponding relationship of at least one parameter of the plurality of antenna structures. For example, the above-mentioned corresponding relationship can be pre-configured in the terminal device and the network device according to the types of antenna structures existing in the system. If only the second antenna structure and the third antenna structure exist in the system, the corresponding relationship of at least one parameter of the first parameter, the second parameter and the third parameter in the single-panel working state and in the multi-panel working state of the second antenna structure and the third antenna structure can be pre-configured in the terminal device and the network device. As an example, a possible pre-configured corresponding relationship is given in Table 2.

[0104] Table 2

[0105]

[0106] Optionally, the preconfigured correspondence can also be protocol predefined.

[0107] Optionally, when the antenna structure of the terminal device is the first antenna structure, the first indication information indicates at least one of the following correspondences: the value of the first parameter becomes smaller when the terminal device changes from the single-panel state to the multi-panel state, or the value of the second parameter remains unchanged when the terminal device changes from the single-panel state to the multi-panel state, or the value of the third parameter becomes smaller when the terminal device changes from the single-panel state to the multi-panel state.

[0108] Optionally, when the antenna structure of the terminal device is the second antenna structure, the first indication information indicates at least one of the following correspondences: the value of the first parameter becomes larger or remains unchanged when the terminal device changes from the single-panel state to the multi-panel state, or the value of the second parameter remains unchanged when the terminal device changes from the single-panel state to the multi-panel state, or the value of the third parameter becomes larger or remains unchanged when the terminal device changes from the single-panel state to the multi-panel state.

[0109] Optionally, when the antenna structure of the terminal device is the third antenna structure, the first indication information indicates at least one of the following correspondences: the value of the first parameter becomes smaller or remains unchanged when the terminal device changes from the single-panel state to the multi-panel state, or the value of the second parameter becomes larger or remains unchanged when the terminal device changes from the single-panel state to the multi-panel state, or the value of the third parameter remains unchanged when the terminal device changes from the single-panel state to the multi-panel state.

[0110] It should be noted that in the above scheme, whether the described antenna is a logical antenna or a physical antenna is not limited, and similarly, whether the panel in the antenna structure used by the terminal device is a logical panel or a physical panel is also not limited. There is a correspondence between the logical antenna and the physical antenna, and the present application does not limit how the logical antenna and the physical antenna realize mutual conversion through the correspondence between them. For example, the logical antenna and the physical antenna are one-to-one mapping, or one-to-many mapping, or many-to-one mapping, or multiple logical antennas are mapped to multiple physical antennas through linear combination. Similarly, there is a correspondence between the logical panel corresponding to a panel and the physical panel corresponding to the panel, and the present application does not limit how the logical panel and the physical panel realize mutual conversion through the correspondence between them. For example, the logical panel and the physical panel are one-to-one mapping, or one-to-many mapping, or many-to-one mapping, or multiple logical panels are mapped to multiple physical panels through linear combination.

[0111] In the following, the present application gives the possible connection modes of the three antenna structures when the panel in the antenna structure used by the terminal device is a physical panel.

[0112] (1) The antenna structure of the terminal device is a first antenna structure. The first antenna structure includes multiple panels, and each panel includes one or more antenna arrays. Each antenna array includes a first antenna subset and a second antenna subset. When the terminal device is in a single panel state, the first antenna subset in each antenna array of the single panel is connected to a first channel, and the second antenna subset is connected to a second channel. The first channel and the second channel are different. When the terminal device is in a multi-panel state, the first antenna subset in each antenna array of each panel is connected to a channel, and the second antenna subset is not connected to a channel.

[0113] Optionally, the antenna elements included in the first antenna element set have the same polarization direction.

[0114] Optionally, the antenna elements included in the second linear array set have the same polarization direction.

[0115] Optionally, the polarization directions of the antenna elements included in the first antenna element set and the antenna elements included in the second antenna element set are orthogonal. Orthogonal polarization directions can be understood as the polarization directions differing by 90 degrees.

[0116] Optionally, when a panel includes multiple antenna arrays, the channels of the multiple antenna arrays are correlated.

[0117] As an example, Figure 5A This is a possible schematic diagram of the first antenna structure, which will be shown here. Figure 5A The antenna structure shown is called structure #0. For example... Figure 5A As shown, structure #0 includes three panels, each containing one antenna array. This antenna array includes a first antenna element set and a second antenna element set. The first antenna element set comprises four antenna elements #1, and the second antenna element set comprises four antenna elements #2. Additionally, structure #0 includes two switches and two analog-to-digital converters (AD) / digital-to-analog converters (AD). The two switches are referred to as switch #1 and switch #2, and the two AD / DA converters as AD / DA #1 and AD / DA #2. One end of switch #1 is connected to AD / DA #1, and the other end of switch #1 is connected to the first antenna element set in each of the three panels. One end of switch #2 is connected to AD / DA #2, and the other end of switch #2 is connected to the second antenna element set in each of the three panels.

[0118] It can be seen that, Figure 5AEach antenna element is also connected to a PS (Power Switch) via its corresponding switch. Therefore, the connection of the other end of switch #1 to antenna element #1 in each of the three panels specifically means that the other end of switch #1 is connected to one end of the PS corresponding to each antenna element #1 in the three panels, and the other end of each PS is connected to the corresponding antenna element. Other similar descriptions will not be repeated here.

[0119] It should be understood that, such as Figure 5A As shown, although the other end of switch #1 is connected to antenna element #1 in each of the three panels, when switch #1 is closed, AD / DA #1 can only connect to the first antenna element set of one of the three panels. Similarly, when switch #2 is closed, AD / DA #2 can only connect to the second antenna element set of one of the three panels.

[0120] (2) The antenna structure of the terminal device is a second antenna structure. The second antenna structure includes multiple panels, and each panel includes one or more antenna arrays. Each antenna array includes a first antenna subset and a second antenna subset. When the terminal device is in a single-panel state, the first antenna subset in each antenna array of the single panel is connected to the first channel, and the second antenna subset is connected to the second channel. The first channel and the second channel are different. When the terminal device is in a multi-panel state, the first antenna subset in each antenna array of each panel in the multi-panel state is connected to the third channel, and the second antenna subset is connected to the fourth channel. The third channel and the fourth channel are different.

[0121] As an example, Figure 5B This is a possible schematic diagram of the second antenna structure, which will be shown here. Figure 5B The antenna structure shown is called structure #1. For example... Figure 5BAs shown, structure #1 includes 3 panels, each of which includes a set of antenna arrays, the set of antenna arrays including a first set of antenna elements and a second set of antenna elements, wherein the first set of antenna elements includes 4 antenna elements #1 and the second set of antenna elements includes 4 antenna elements #2. In addition, structure #1 also includes 4 switches and 4 AD / DA, which are referred to as switch #1, switch #2, switch #3 and switch #4, and AD / DA #1, AD / DA #2, AD / DA #3 and AD / DA #4. Wherein one end of switch #1 is connected with AD / DA #1, the other end of switch #1 is connected with antenna elements #1 in 3 panels respectively, one end of switch #2 is connected with AD / DA #2, the other end of switch #2 is connected with antenna elements #1 in 3 panels respectively, one end of switch #3 is connected with AD / DA #3, the other end of switch #3 is connected with antenna elements #2 in 3 panels respectively, one end of switch #4 is connected with AD / DA #4, the other end of switch #4 is connected with antenna elements #2 in 3 panels respectively.

[0122] It should be understood that in the case of switch #1 closing, AD / DA #1 can only communicate with the first set of antenna elements of one of the 3 panels. In the case of switch #2 closing, AD / DA #2 can only communicate with the second set of antenna elements of one of the 3 panels. In the case of switch #3 closing, AD / DA #3 can only communicate with the first set of antenna elements of one of the 3 panels. In the case of switch #4 closing, AD / DA #4 can only communicate with the second set of antenna elements of one of the 3 panels.

[0123] (3) The antenna structure of the terminal device is a third antenna structure. The third antenna structure includes multiple panels, and each panel includes a first antenna array and a second antenna array. The first antenna array includes a first antenna subarray and a second antenna subarray, and the second antenna array includes a third antenna subarray and a fourth antenna subarray. When the third structure is in a single panel state, the first antenna subarray of the first antenna array of the single panel is connected to the first channel, the second antenna subarray of the first antenna array of the single panel is connected to the second channel, the third antenna subarray of the second antenna array of the single panel is connected to the third channel, and the fourth antenna subarray of the second antenna array of the single panel is connected to the fourth channel. The first channel, the second channel, the third channel, and the fourth channel are different. When the third structure is in a multi-panel state, the first antenna subarray of the first antenna array of the first panel and the third antenna subarray of the second antenna array of the first panel are both connected to the fifth channel, and the second antenna subarray of the first antenna array of the first panel and the fourth antenna subarray of the second antenna array of the first panel are both connected to the sixth channel. The fifth channel and the sixth channel are different. The first panel is a single panel that operates in the multi-panel working state.

[0124] As an example, Figure 5C This is a possible schematic diagram of a third antenna structure, which will be shown here. Figure 5C The antenna structure shown is called structure #2. Figure 5C Structure #2 shown includes three panels. To simplify the connection lines, only the connection between two panels is drawn, omitting the connection between the third panel. For example... Figure 5C As shown, each panel includes two antenna arrays, and each antenna array includes a first antenna element set and a second antenna element set. The first antenna element set includes two antenna elements #1, and the second antenna element set includes two antenna elements #2. With two panels shown, the structure also includes eight switches, four AD / DA converters, and four combiners. Here, the eight switches are referred to as switch #1, switch #2, switch #3, switch #4, switch #5, switch #6, switch #7, and switch #8; the four AD / DA converters are referred to as AD / DA #1, AD / DA #2, AD / DA #3, and AD / DA #4; and the four combiners are referred to as combiner #1, combiner #2, combiner #3, and combiner #4.

[0125] like Figure 5CAs shown, one end of switch #1 is fixedly connected with AD / DA #1, one end of switch #2 is fixedly connected with AD / DA #2, one end of switch #3 is fixedly connected with AD / DA #3, and one end of switch #4 is fixedly connected with AD / DA #4. The other end of switch #1 to switch #4 is connected with the opening or closing state of switch #5 to switch #8. It should be noted that when switch #5 to switch #8 moves according to the direction of the arrow on the switch, it indicates that the switch is closed, and when switch #5 to switch #8 moves in the opposite direction of the arrow on the switch, it indicates that the switch is opened. Specifically, when switch #5 is opened, the first antenna array set of the first group of antenna arrays of panel #1 is connected with the other end of switch #1, and the first antenna array set of the second group of antenna arrays of panel #1 is connected with the other end of switch #3; when switch #5 is closed, the first antenna array set of the first group of antenna arrays of panel #1 and the first antenna array set of the second group of antenna arrays of panel #1 are both connected with one end of combiner #1, and the other end of combiner #1 is connected with the other end of switch #1. When switch #6 is opened, the second antenna array set of the first group of antenna arrays of panel #1 is connected with the other end of switch #2, and the second antenna array set of the second group of antenna arrays of panel #1 is connected with the other end of switch #4; when switch #6 is closed, the second antenna array set of the first group of antenna arrays of panel #1 and the second antenna array set of the second group of antenna arrays of panel #1 are both connected with one end of combiner #2, and the other end of combiner #2 is connected with the other end of switch #2. Similarly, when switch #7 is opened, the first antenna array set of the first group of antenna arrays of panel #2 is connected with the other end of switch #1, and the first antenna array set of the second group of antenna arrays of panel #2 is connected with the other end of switch #3; when switch #7 is closed, the first antenna array set of the first group of antenna arrays of panel #2 and the first antenna array set of the second group of antenna arrays of panel #2 are both connected with one end of combiner #3, and the other end of combiner #3 is connected with the other end of switch #3. When switch #8 is opened, the second antenna array set of the first group of antenna arrays of panel #2 is connected with the other end of switch #2, and the second antenna array set of the second group of antenna arrays of panel #2 is connected with the other end of switch #4; when switch #8 is closed, the second antenna array set of the first group of antenna arrays of panel #2 and the second antenna array set of the second group of antenna arrays of panel #2 are both connected with one end of combiner #4, and the other end of combiner #4 is connected with the other end of switch #4.

[0126] It can be understood that the connection mode of the third panel can refer to the connection mode of the two panels drawn, which will not be repeated here.

[0127] It should be understood that the three structures shown in FIG. 5 only draw important devices and do not draw all device configurations. For example, PS is not drawn in structure #1 and structure #2, which does not mean that there is no PS, but in order to more clearly show the difference between the three structures, the connection of PS is omitted, and the connection of PS can be referred to the description in Figure 5A and Figure 5A , which will not be repeated here. In addition, the number of panels, the number of antenna arrays, and the number of AD / DA in FIG. 5 are examples and do not constitute any limitation.

[0128] The values of the first parameter to the third parameter in the terminal device in the single-panel working state and in the multi-panel working state will be described below in combination with the structure #0 of Figure 5A . As an example, structure #0 works in single panel, AD / DA #1 and AD / DA #2 are connected with the left panel; works in multi-panel, AD / DA #1 is connected with the left panel, and AD / DA #2 is connected with the right panel. When working in single panel, the single panel is connected with two AD / DA, therefore, the number of channels corresponding to the single panel is 2 (i.e. the value of the first parameter); in addition, since one channel connects 4 antenna arrays, it is assumed here that the power of the received signal corresponding to 4 first antenna arrays or 4 second antenna arrays is P1 (P>0), then the power of the received signal of each channel is P (i.e. the value of the second parameter); in addition, the power of the received signal of the single panel is the product of the number of channels corresponding to the single panel and the power of the received signal of each channel, i.e. the power of the received signal of the single panel is 2*P1 (i.e. the value of the third parameter).

[0129] Similarly, when working in multi-panel (2 panels), each working panel can only be connected with one AD / DA, therefore, the number of channels corresponding to each working panel is 1; in addition, since the number of antenna arrays connected by each AD / DA (i.e. each channel) does not change, the received power of each channel is still P1; in addition, each panel only corresponds to one channel, and the received power of each digital channel is P1, therefore, the power of the received signal of each panel is 1*P1.

[0130] As an example, structure #1 of Figure 5B works in single panel, AD / DA #1 to AD / DA #4 are connected with the left panel, or AD / DA #1 and AD / DA #2 are connected with the left panel; works in multi-panel, AD / DA #1 and AD / DA #2 are connected with the left panel, and AD / DA #3 and AD / DA #4 are connected with the right panel. Figure 5CWhen the structure #2 works in single panel, the switch #5 and the switch #6 are disconnected, and the AD / DA #1 to the AD / DA #4 are connected to the left panel; when the structure #2 works in multiple panels, the switch #5, the switch #6, the switch #7 and the switch #8 are all closed, and the AD / DA #1 and the AD / DA #2 are connected to the left panel, and the AD / DA #3 and the AD / DA #4 are connected to the right panel, and in the above connection mode, the values of the first parameter, the second parameter and the third parameter of the structure #1 and the structure #2 when working in single panel and multiple panels are shown in Table 3, which will not be repeated here. Wherein, P2 is the power of the received signal corresponding to the 4 first antenna elements or the 4 second antenna elements in the structure #1, P3 is the power of the received signal corresponding to the 4 first antenna elements or the 4 second antenna elements in the structure #3, and P2 and P3 are greater than 0.

[0131] Table 3

[0132]

[0133] It should be noted that, Figure 5B When the structure #1 works in single panel, when the AD / DA #1 to the AD / DA #4 are connected to the left panel, since the AD / DA #1 and the AD / DA #3 are connected to the 4 first antenna elements of the first antenna element set in the left panel, and the AD / DA #2 and the AD / DA #4 are connected to the 4 second antenna elements of the second antenna element set in the left panel, therefore, when the structure #1 works in single panel, although it is connected to the 4 AD / DA, in fact, it only corresponds to 2 different channels. Therefore, in practice, when the structure #1 works in single panel, only one of the AD / DA #1 and the AD / DA #3 and one of the AD / DA #2 and the AD / DA #4 can be connected to the left panel.

[0134] In addition, from Table 3, it can be seen that the structure #2 proposed in the present application can receive data from 4 channels in single panel working state, while the structure #0 and the structure #1 can only receive data from 2 channels in single panel working state. At the same time, the structure #0 can receive data from 1 channel in multiple panel working state, the structure #1 can receive data from 2 channels in multiple panel working state, and the structure #2 proposed in the present application can receive data from 2 channels for each panel in multiple panel working state, therefore, it can be seen that the reliability of the received data of the structure #2 in single panel working state will be higher than that of the other two structures, and at the same time, the performance of the received data of the structure #2 in multiple panel working state will not decrease compared with the other two structures.

[0135] It should be understood that only one possible connection structure of the first antenna structure, the second antenna structure and the third antenna structure is given in FIG. 5, and in practice, there can be more possible connection manners of the above three structures, which will not be described herein.

[0136] S402, the terminal device sends first indication information to the network device. Correspondingly, the network device receives the first indication information from the terminal device.

[0137] S403, the network device performs data scheduling according to the first indication information.

[0138] Specifically, the network device can perform data scheduling more suitable for the terminal device according to the first indication information. For example, when the first indication information indicates that the first parameter decreases, the network device can schedule more resources or send higher power to compensate for the loss caused by the decrease in the number of channels due to the change in the panel working state; similarly, when the first indication information indicates that the second parameter decreases, the network device needs to send a larger signal power to compensate for the power loss caused by the change in the panel working state.

[0139] As can be seen from the above, the performance of the terminal device in the single-panel working state and in the multi-panel working state is different. Therefore, the terminal device reports the first indication information, which is beneficial to the network device to perform data scheduling according to the first indication information and improve the performance of communication. The beneficial effect is illustrated by way of example as follows.

[0140] As an example, taking the case that the antenna structure of the terminal device in the system includes structure #0, structure #1 and structure #2, and table 1 is preconfigured in the terminal device and the network device as an example, it is assumed that the network device learns the corresponding relationship of table 1 according to the first indication information, when the antenna structure adopted by the terminal device is structure #0, it can be seen from table 1 that the signal receiving power of the working panel (i.e. the value of the third parameter) in the multi-panel working state of structure #0 will decrease. When the terminal device switches from the single-panel state to the multi-panel working state, the network device will perform power compensation when sending downlink data. Or, when the terminal device switches from the multi-panel state to the single-panel working state, the network device will perform power reduction when sending downlink data.

[0141] Based on the above steps S401 to S403, in an optional embodiment, it further includes step S404: the terminal device sends second indication information to the network device, the second indication information being used to indicate the panel state of the terminal device.

[0142] Specifically, the panel state can be a single-panel state, can be a multi-panel state, or can be switching between the single-panel state and the multi-panel state. For example, the second indication information is used to indicate that the terminal device switches from the single-panel state to the multi-panel state, or is used to indicate that the terminal device switches from the multi-panel working state to the single-panel working state, or is used to indicate that the terminal device is in the single-panel state, or is used to indicate that the terminal device is in the multi-panel working state.

[0143] It should be understood that the second indication information can be information different from the first indication information, or the second indication information can also be carried in the first indication information, that is, the first indication information simultaneously indicates the above-mentioned corresponding relationship and the panel state of the terminal device.

[0144] As an example, in combination with S404, in a specific implementation, the network device considers that the terminal device is currently in the single-panel working state, and then the network device receives the first indication information and the second indication information from the terminal device, wherein the first indication information is used to indicate that the values of the third parameter when the terminal device is in the single-panel working state and in the multi-panel working state are P and 2*P respectively, or the first indication information is used to indicate that the value of the third parameter when the terminal device is in the single-panel state is less than the value of the third parameter when the terminal device is in the multi-panel state, that is, the first indication information indicates that the signal receiving power of the working panel of the terminal device in the multi-panel working state (that is, the value of the third parameter) will be reduced, and the second indication information is used to indicate that the terminal device is currently in the multi-panel working state. Then, the network device can determine that the terminal device has changed from the single-panel working state to the multi-panel working state according to the second indication information, and simultaneously, the network device determines that power compensation needs to be performed when the network device sends downlink data to the terminal device in the multi-panel working state according to the first indication information.

[0145] In addition, the three antenna structures can all support multi-panel working, that is, at least two panels can work simultaneously at the same time. When performing beam training, the terminal device can complete the training of at least two beams at the same time (assuming that each panel emits one beam), thereby reducing the overhead of beam training and improving system performance and reducing the energy consumption of the network device and the terminal device. Figure 3C For example, in step 3 of the beam training, M2=3, if the terminal device can implement 3-panel working, then the terminal device can emit 3 beams simultaneously, and the network device simultaneously detects the 3 beams emitted by the terminal device using beam #3. Compared with the current process in which the terminal device needs to emit three times, each time emitting one beam, and the corresponding network device receives three times, each time receiving one beam, and detects each received beam using beam #3, the energy consumption of the network device and the terminal device can be reduced, that is, the overhead of beam training is reduced, and system performance is improved.
