As shown in fig. 1, the communication system comprises a radio access network 100 and a core network 200, and optionally the communication system 1000 may further comprise the internet 300. The radio access network 100 may include at least one radio access network device (e.g., 110a and 110b in fig. 1) and may also include at least one terminal (e.g., 120a-120j in fig. 1). The terminal is connected with the wireless access network equipment in a wireless mode, and the wireless access network equipment is connected with the core network in a wireless or wired mode. The core network device and the radio access network device may be separate physical devices, or may integrate the functions of the core network device and the logic functions of the radio access network device on the same physical device, or may integrate the functions of part of the core network device and part of the radio access network device on one physical device. The terminals and the radio access network device may be connected to each other by wired or wireless means. Fig. 1 is only a schematic diagram, and other network devices may be further included in the communication system, for example, a wireless relay device and a wireless backhaul device may also be included, which are not shown in fig. 1.
The radio access network device may be a base station (base station), an evolved NodeB (eNodeB), a transmission and reception point (transmission reception point, TRP), a next generation NodeB (gNB) in a fifth generation (5th generation,5G) mobile communication system, a next generation base station in a sixth generation (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 present application may also be a module or unit that performs a function of a base station part, for example, a Central Unit (CU) or a Distributed Unit (DU). The CU can complete the functions of a radio resource control protocol and a packet data convergence layer protocol (packet data convergence protocol, PDCP) of the base station and can also complete the functions of a service data adaptation protocol (service data adaptation protocol, SDAP); the DU performs the functions of the radio link control layer and the medium access control (medium access control, MAC) layer of the base station, and may also perform the functions of a part of the physical layer or the entire physical layer, and for a detailed description of the above protocol layers, reference may be made to the relevant technical specifications of the third generation partnership project (3rd generation partnership project,3GPP). The radio access network device may be a macro base station (e.g. 110a in fig. 1), a micro base station or an indoor station (e.g. 110b in fig. 1), a relay node or a donor node, etc. The embodiment of the application does not limit the specific technology and the specific equipment form adopted by the wireless access network equipment. For convenience of description, a base station will be described below as an example of a radio access network device.
A terminal may also be referred to as a terminal device, user Equipment (UE), mobile station, mobile terminal, etc. The terminal may be widely applied to various scenes, for example, device-to-device (D2D), vehicle-to-device (vehicle to everything, V2X) communication, machine-type communication (MTC), internet of things (internet of things, IOT), virtual reality, augmented reality, industrial control, autopilot, telemedicine, smart grid, smart furniture, smart office, smart wear, smart transportation, smart city, and the like. The terminal can be a mobile phone, a tablet personal computer, a computer with a wireless receiving and transmitting function, a wearable device, a vehicle, an unmanned aerial vehicle, a helicopter, an airplane, a ship, a robot, a mechanical arm, intelligent household equipment and the like. The embodiment of the application does not limit the specific technology and the specific equipment form adopted by the terminal.
The base station and the terminal may be fixed in position or movable. Base stations and terminals may be deployed on land, including indoors or outdoors, hand-held or vehicle-mounted; the device can be deployed on the water surface; but also on aircraft, balloons and satellites. The embodiment of the application does not limit the application scenes of the base station and the terminal.
The roles of base station and terminal may be relative, e.g., helicopter or drone 120i in fig. 1 may be configured as a mobile base station, terminal 120i being the base station for those terminals 120j that access radio access network 100 through 120 i; but for base station 110a 120i is a terminal, i.e., communication between 110a and 120i is via a wireless air interface protocol. Of course, communication between 110a and 120i may be performed via an interface protocol between base stations, and in this case, 120i is also a base station with respect to 110 a. Thus, both the base station and the terminal may be collectively referred to as a communication device, 110a and 110b in fig. 1 may be referred to as a communication device having base station functionality, and 120a-120j in fig. 1 may be referred to as a communication device having terminal functionality.
Communication can be carried out between the base station and the terminal, between the base station and between the terminal and the terminal through the authorized spectrum, communication can be carried out through the unlicensed spectrum, and communication can also be carried out through the authorized spectrum and the unlicensed spectrum at the same time; communication can be performed through a frequency spectrum of 6 gigahertz (GHz) or less, communication can be performed through a frequency spectrum of 6GHz or more, and communication can be performed using a frequency spectrum of 6GHz or less and a frequency spectrum of 6GHz or more simultaneously. The embodiment of the application does not limit the spectrum resources used by the wireless communication.
In the embodiment of the present application, the functions of the base station may be performed by a module (such as a chip) in the base station, or may be performed by a control subsystem including the functions of the base station. The control subsystem comprising the base station function can be a control center in the application scenarios of smart power grids, industrial control, intelligent transportation, smart cities and the like. The functions of the terminal may be performed by a module (e.g., a chip or a modem) in the terminal, or by a device including the functions of the terminal.
In the application, a base station sends a downlink signal or downlink information to a terminal, and the downlink information is borne 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 for a terminal to communicate with a base station, it is necessary to establish a radio connection with a cell controlled by the base station. The cell with which the terminal has established a radio connection is called the serving cell of the terminal. The terminal may also be interfered by signals from neighboring cells when communicating with the serving cell.
Depending on whether the specification applies to the alternatives: in an embodiment of the present application, the time domain symbol may be an orthogonal frequency division multiplexing (orthogonal frequency division multiplexing, OFDM) symbol, or may be a discrete fourier transform spread OFDM (Discrete Fourier Transform-spread-OFDM, DFT-s-OFDM) symbol. Symbols in embodiments of the present application refer to time domain symbols unless otherwise specified.

In order to facilitate understanding of the technical solution of the present application, concepts and related processes related to the present application will be described first.
1. A panel: the panel is made up of antennas, so the panel may also be referred to as an antenna panel. Since antennas have two understandings, one is a logical antenna concept and the other is a physical antenna entity. Thus, the panel of the present application may be formed by a logic antenna, which may also be referred to as a logic panel, and the panel of the present application may be formed by a physical entity antenna, which may also be referred to as a physical panel. When the panel is in a working state, a group of beams formed by the antenna arrays of the panel can transmit signals, and a group of beams formed by the antenna arrays of different panels can be independently adjusted. A terminal device may comprise a plurality of panels, and only one of the plurality of panels comprised by the terminal device may be operated at the same time, i.e. the terminal device is in a single panel operating state. Correspondingly, at least two of the plurality of panels included in the terminal device can also work at the same time, and the terminal device is in a multi-panel working state at the moment. It should be understood that the terminal device in the present application includes a plurality of panels, and when the panels are solid panels, the terminal device may be considered to include a plurality of panels, and when the panels are logical panels, the terminal device may be considered to correspond to a plurality of panels. The following will each take an example in which the terminal device includes a plurality of panels.
2. Beam training (beam training): as shown in fig. 2, the purpose of beam training is to find a slash-filled beamlet (i.e., an optimal beamlet pair) among a number of possible beams corresponding to the network device and the terminal device. In fig. 2, the network device transmits or receives signals by using the beam filled with the diagonal beam, and the corresponding terminal device also receives or transmits signals by using the beam filled with the diagonal beam, so that the strength of the signals can be maximized, and the optimal communication performance can be achieved. In one technique, beam training is divided into the following 3 steps, which are described in detail below in connection with fig. 3.
Step 1: wide beam training for network devices and terminal devices.
In this step, as shown in fig. 3A, the network device transmits a series of wide beams, for example, N1 wide beams. Correspondingly, the terminal device receives with a series of wide beams, assuming M1 wide beams. The terminal device may detect an optimal one of the N1 x M1 pairs of beam pairs, i.e. complete the training of the wide beam pair. The resulting optimal wide beam pair is denoted (beam #1, beam # 2), where beam #1 represents the resulting optimal wide beam of the network device and beam #2 represents the resulting optimal wide beam of the terminal device.
And 2, training the beamlets of the network equipment.
On the basis of step 1, as shown in fig. 3B, the network device sends a series of beamlets on the basis of the wide beam, i.e. beam #1, for example, N2 beamlets are sent, and the terminal device detects with beam #2 to obtain an optimal beamlet of the network device, denoted as beam #3, and completes the beamlet training of the network device.
Step 3: and (3) beamlet training of the terminal equipment.
On the basis of step 2, as shown in fig. 3C, the fixed network device trains the beamlets, and the terminal device finds the optimal beamlets. Specifically, the terminal device transmits a series of beamlets, for example, M2 beamlets, on the basis of the wide beam, beam # 2. The network device detects with the beam #3 to obtain the optimal beamlets of the terminal device, which is marked as the beam #4, and the beamlet training of the terminal device is completed.
Through the above 3 steps, the network device and the terminal device obtain an optimal pair of beamlets (beam #3, beam # 4), which can then be used for data transmission. It should be understood that steps 1 through 3 are merely for the purpose of illustrating a specific method of beam training and are not limiting of a specific order of training. For example, step 1 may be performed to obtain an optimal wide beam pair, then the terminal device side may perform the beamlet training, and then the network side may perform the beamlet training according to the beamlet training performed at the terminal side.
In step 1 and step 3, the terminal device can only transmit one beam at the same time to perform beam training in a single panel working state, and for a plurality of beams of the terminal device and a plurality of beams of the network device, the terminal device determines an optimal beam pair according to sequential or periodic one-time training, which results in greater beam training overhead, reduced system capacity and improved energy consumption of the network device and the terminal device.
In view of the above, the present application provides a method capable of effectively solving the above technical problems. The method according to the present application will be described in detail.
As shown in fig. 4, fig. 4 is a schematic flow chart of a communication method proposed by the present application. The method shown in fig. 4 may include the following operations.
S401, the terminal equipment generates first indication information.
The first indication information is used for indicating a corresponding relation of at least one parameter in a single-panel (single-panel) working state and a multi-panel (multi-panel) working state of the terminal equipment, wherein the at least one parameter comprises at least one of a first parameter, a second parameter or a third parameter, the terminal equipment comprises a plurality of panels (panels), the panels comprise a first panel, the first parameter is the number of signal transmission channels corresponding to the first panel, the second parameter is the power of a received signal on each channel corresponding to the first panel, and the third parameter is the power of the received signal of the first panel.
Alternatively, the first indication information may indicate a specific value of at least one parameter in the single panel operating state and in the multi-panel operating state of the terminal device, and/or a magnitude relation of at least one parameter in the single panel operating state and in the multi-panel operating state of the terminal device. The following is a detailed description.
The content indicated by the first indication information may also be described as that the first information is used to indicate that when the terminal device changes from the single-panel operation to the multi-panel operation, or when the terminal device changes from the multi-panel operation to the single-panel operation, the value of one or more parameters of the first parameter, the second parameter and the third parameter corresponding to the first panel increases, decreases or remains unchanged.
As an example, the first information may be used to indicate when the terminal device changes from the single panel operation to the multi-panel operation, or when the terminal device changes from the multi-panel operation to the single panel operation, the value of one or more of the first parameter, the second parameter, and the third parameter corresponding to the first panel increases by a factor P, decreases by a factor Q, or remains unchanged. Wherein P and Q are greater than 0. It should be further understood that the first parameter is the number of signal transmission channels corresponding to the first panel, and specifically refers to the maximum number of channels that can be supported when the terminal device uses the first panel to perform signal transmission. By way of example, a channel may refer to an antenna port (port), or a digital channel, or an analog channel, and the application is not particularly limited.
When the terminal device is in a single panel operating state, the first panel is the only operating panel in the single panel state.
When the terminal device is in the multi-panel working state, the first panel is one or more of the panels of the terminal device working in the multi-panel working state, or can be each of the panels of the terminal device working in the multi-panel working state.
When the first panel is each of the operating panels among the plurality of panels, that is, each of the plurality of panels operating simultaneously satisfies the correspondence indicated by the first indication information.
When the first panel is one or more of the plurality of panels, that is, only one of the plurality of panels that operate simultaneously may satisfy the correspondence indicated by the first indication information, in this manner, optionally, the terminal device sends the first indication information to the network device, and may indicate the first panel through the first indication information or other information. For example, the terminal device includes 3 panels, namely, panel 1, panel 2 and panel 3, when the terminal device is in the multi-panel working state, the panel 1 and the panel 2 work simultaneously, and the panel 1 satisfies the corresponding relationship indicated by the first indication information, so that the terminal device can also indicate the panel 1 to the network device through the first indication information or other information.
In practice, different terminal devices may employ different antenna structures. The following application provides the correspondence of the first parameter, the second parameter and the third parameter in the case of the single panel and the multi-panel operation of three different antenna structures.
(1) The terminal equipment adopts a first antenna structure: the number of the panels is X0 (X0 is more than or equal to 2), the first antenna structure meets the following characteristics that the number of channels corresponding to at least one panel in the plurality of working panels is smaller than the number of channels corresponding to the working panel when the terminal equipment is in the single-panel working state. Under the condition that the terminal equipment works on the single panel and the multiple panels, the corresponding relation among the first parameter, the second parameter and the third parameter is as follows:
(1) in the single panel working state, the value of the first parameter is Y0, the value of the second parameter is P0, the value of the third parameter is P0X Y0, wherein X0 and Y0 are positive integers, and P0 is more than 0.
(2) When the multi-panel is in a working state, the value of the first parameter is Z0, Z0 is smaller than Y0, the value of the second parameter is P0, and the value of the third parameter is Z0X Y0, wherein Z0 is a positive integer.
(2) The terminal equipment adopts a second antenna structure: the number of the panels is X1 (X1 is more than or equal to 2), and the second antenna structure meets the following characteristics: the number of channels corresponding to each of the plurality of working panels when the terminal device is in the multi-panel working state is not less than the number of channels corresponding to the working panels when the terminal device is in the single-panel working state. Under the condition that the terminal equipment works on the single panel and the multiple panels, the corresponding relation among the first parameter, the second parameter and the third parameter is as follows:
(1) In the single panel working state, the value of the first parameter is Y1, the value of the second parameter is P1, the value of the third parameter is P1X Y1, wherein X1 and Y1 are positive integers, and P1 is more than 0.

(3) The terminal equipment adopts a third antenna structure: the number of the panels is X2 (X2 is more than or equal to 2), and the third antenna structure meets the following characteristics: the number of channels corresponding to at least one of the plurality of working panels when the terminal equipment is in the multi-panel working state is not greater than the number of channels corresponding to the working panel when the terminal equipment is in the single-panel working state, and the power of the received signals on at least one of the channels on the working panel with the reduced number of channels is increased when the terminal equipment is in the multi-panel working state. Under the condition that the terminal equipment works on the single panel and the multiple panels, the corresponding relation among the first parameter, the second parameter and the third parameter is as follows:
(1) in the single panel working state, the value of the first parameter is Y2, the value of the second parameter is P2, the value of the third parameter is P2X Y2, wherein X2 and Y2 are positive integers, and P2 is more than 0.
(2) When the multi-panel is in a working state, the value of the first parameter is Z2, Z2 is smaller than or equal to Y2, the value of the second parameter is Q2, Q2 is larger than or equal to P2, the value of the third parameter is Z2X Y2, and P2X Y2 is equal to Z2X Y2, wherein Z2 is a positive integer.
In summary, when the terminal device adopts the first antenna structure to the third antenna structure, the corresponding relationship between the first parameter, the second parameter and the third parameter is shown in table 1 when the single panel and the multi-panel operate.
TABLE 1
Optionally, before the terminal device sends the first indication information, a correspondence relationship of at least one parameter of the plurality of antenna structures may be preconfigured between the terminal device and the network device. For example, the correspondence relationship may be preconfigured in the terminal device and the network device according to the kind of the antenna structure existing in the system. If only the second antenna structure and the third antenna structure exist in the system, the corresponding relation of at least one of the first parameter, the second parameter and the third parameter in the single-panel working state and the multi-panel working state of the second antenna structure and the third antenna structure can be preconfigured in the terminal equipment and the network equipment. As an example, one possible pre-configured correspondence is given in table 2.
TABLE 2
Optionally, the pre-configured correspondence may be predefined by a protocol.
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 correspondence relations: when the terminal device changes from the single-sided state to the multi-sided state, the value of the first parameter becomes smaller, or when the terminal device changes from the single-sided state to the multi-sided state, the value of the second parameter is unchanged, or when the terminal device changes from the single-sided state to the multi-sided state, the value of the third parameter becomes smaller.
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 correspondence relations: the value of the first parameter becomes larger or unchanged when the terminal device is changed from the single-sided state to the multi-sided state, or the value of the second parameter is unchanged when the terminal device is changed from the single-sided state to the multi-sided state, or the value of the third parameter is larger or unchanged when the terminal device is changed from the single-sided state to the multi-sided state.
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 correspondence relations: the value of the first parameter becomes smaller or unchanged when the terminal device is changed from the single-sided state to the multi-sided state, or the value of the second parameter becomes larger or unchanged when the terminal device is changed from the single-sided state to the multi-sided state, or the value of the third parameter is unchanged when the terminal device is changed from the single-sided state to the multi-sided state.
It should be noted that, in the above scheme, whether the described antenna is a logic antenna or a physical antenna is not limited, and whether the panel in the antenna structure adopted by the terminal device is a logic panel or a physical panel is also not limited. The application does not limit how the logic antenna and the entity antenna realize mutual conversion through the corresponding relation between the logic antenna and the entity antenna. For example, the logical antennas and the physical antennas are mapped one-to-one, or one-to-many, or many-to-one, or the plurality of logical antennas are mapped to the plurality of physical antennas by linear combination. Similarly, there is a correspondence between a logical panel corresponding to a panel and a physical panel corresponding to the panel, and the application does not limit how the logical panel and the physical panel implement mutual conversion through the correspondence between them. For example, a one-to-one mapping between a logical panel and a physical panel, or a one-to-many mapping, or a many-to-one mapping, or a plurality of logical panels mapping to a plurality of physical panels by linear combinations.
In the following, the application provides three possible connection modes of the antenna structure when the panel in the antenna structure adopted by the terminal equipment is a solid panel.
(1) The antenna structure of the terminal equipment is a first antenna structure. The first antenna structure comprises a plurality of panels, each panel of the plurality of panels comprises one or more groups of antenna arrays, wherein each group of antenna arrays comprises a first antenna array subset and a second antenna array subset, when the terminal equipment is in a single-panel state, the first antenna array subset in each group of antenna arrays of the single panel is connected with a first channel, the second antenna array subset is connected with a second channel, the first channel is different from the second channel, when the terminal equipment is in a multi-panel state, the first antenna array subset in each group of antenna arrays of each panel of the plurality of panels is connected with one channel, and the second antenna array subset is not connected with the channel.
Optionally, the polarization directions of the antenna elements included in the first antenna array subset are the same.
Optionally, the polarization directions of the antenna elements included in the second antenna array subset are the same.
Optionally, the polarization directions of the antenna elements included in the first antenna array subset and the antenna elements included in the second antenna array subset are orthogonal. It is understood that the polarization directions are orthogonal may be considered as the two polarization directions are 90 degrees apart.
Alternatively, when multiple sets of antenna arrays are included in one panel, the channels of the multiple sets of antenna arrays are correlated.
As an example, fig. 5A is a schematic diagram of one possible first antenna structure, where the antenna structure shown in fig. 5A is referred to herein as structure #0. As shown in fig. 5A, the structure #0 includes 3 panels, each panel includes 1 group of antenna arrays, and the 1 group of antenna arrays includes a first antenna array subset and a second antenna array subset, where the first antenna array subset includes 4 antenna arrays #1, and the second antenna array subset includes 4 antenna arrays #2. In addition, the structure #0 further includes two switches, which are referred to herein as a switch #1 and a switch #2, and two analog-to-digital converter (AD)/digital-to-analog converters (AD), which are referred to herein as AD/DA #1 and AD/DA #2. One end of the switch #1 is connected with the AD/DA #1, the other end of the switch #1 is connected with the first antenna array subset of the 3 panels respectively, one end of the switch #2 is connected with the AD/DA #2, and the other end of the switch #2 is connected with the second antenna array subset of the 3 panels respectively.
It can be seen that in fig. 5A, one PS is further connected between each antenna element and the corresponding switch, so that the connection between the other end of the switch #1 and the antenna element #1 of the 3 panels respectively means that the other end of the switch #1 is connected to one end of the PS corresponding to each antenna element #1 of the 3 panels respectively, and the other end of each PS is connected to the corresponding antenna element. Other similar descriptions are not repeated here.
It should be understood that, as shown in fig. 5A, while the other ends of the switches #1 are connected to the antenna array #1 of the 3 panels, respectively, the AD/DA #1 can only communicate with the first antenna array subset of one of the 3 panels in the case where the switch #1 is closed. Similarly, with switch #2 closed, AD/DA #2 can only communicate with the second subset of antenna arrays of one of the 3 panels.

As shown in fig. 5B, the structure #1 includes 3 panels, each panel includes 1 group of antenna arrays, and the 1 group of antenna arrays includes a first antenna array subset and a second antenna array subset, where the first antenna array subset includes 4 antenna arrays #1, and the second antenna array subset includes 4 antenna arrays #2. In addition, the configuration #1 further includes 4 switches and 4 AD/DA, where 4 switches are referred to as switch #1, switch #2, switch #3, and switch #4, and 4 AD/DA are referred to as AD/DA #1, AD/DA #2AD/DA #3, and AD/DA #4. One end of the switch #1 is connected with the AD/DA #1, the other end of the switch #1 is connected with the antenna array #1 in the 3 panels, one end of the switch #2 is connected with the AD/DA #2, the other end of the switch #2 is connected with the antenna array #1 in the 3 panels, one end of the switch #3 is connected with the AD/DA #3, the other end of the switch #3 is connected with the antenna array #2 in the 3 panels, one end of the switch #4 is connected with the AD/DA #4, and the other end of the switch #4 is connected with the antenna array #2 in the 3 panels.
It will be appreciated that with switch #1 closed, AD/DA #1 can only communicate with the first subset of antenna arrays of one of the 3 panels. With switch #2 closed, AD/DA #2 can only communicate with the second subset of antenna arrays of one of the 3 panels. With switch #3 closed, AD/DA #3 can only communicate with the first subset of antenna arrays of one of the 3 panels. With switch #4 closed, AD/DA #4 can only communicate with the second subset of antenna arrays of one of the 3 panels.
(3) The antenna structure of the terminal equipment is a third antenna structure. The third antenna structure comprises a plurality of panels, each panel of the plurality of panels comprising a first group of antenna arrays comprising a first subset of antenna arrays and a second subset of antenna arrays comprising a third subset of antenna arrays and a fourth subset of antenna arrays; when the third structure is in a single-panel state, a first antenna array subset of a first group of antenna arrays of the single panel is connected with the first channel, a second antenna array subset of the first group of antenna arrays of the single panel is connected with the second channel, a third antenna array subset of the second group of antenna arrays of the single panel is connected with the third channel, a fourth antenna array subset of the second group of antenna arrays of the single panel is connected with the fourth channel, and 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 array subset of the first group of antenna arrays of the first panel and the third antenna array subset of the second group of antenna arrays of the first panel are connected with the fifth channel, the second antenna array subset of the first group of antenna arrays of the first panel and the fourth antenna array subset of the second group of antenna arrays of the first panel are connected with the sixth channel, the fifth channel is different from the sixth channel, and the first panel is one panel working in the multi-panel working state.
As an example, fig. 5C is a schematic diagram of one possible third antenna structure, where the antenna structure shown in fig. 5C is referred to herein as structure #2. In the structure #2 shown in fig. 5C, three panels are included, and only two panels are drawn for simplifying the connection of the connecting strips, and the connection of the third panel is omitted. As shown in fig. 5C, each panel includes 2 groups of antenna arrays, each group of antenna arrays includes a first antenna array subset including 2 antenna arrays #1 and a second antenna array subset including 2 antenna arrays #2. In the case of two panels being drawn, the structure further includes 8 switches, 4 AD/DA and 4 combiners, where 8 switches are referred to as switch #1, switch #2, switch #3, switch #4, switch #5, switch #6, switch #7 and switch #8,4 AD/DA are referred to as AD/DA #1, AD/DA #2, AD/DA #3 and AD/DA #4, and 4 combiners are referred to as combiner #1, combiner #2, combiner #3 and combiner #4.

The other end connections of switches #1 to #4 are associated with the open or closed state of switches #5 to # 8. Note that, when the switches #5 to #8 are moved in the direction of the arrow on the switches thereof, the switch is closed, and when the switches #5 to #8 are moved in the direction opposite to the direction of the arrow on the switches, the switch is opened. Specifically, when the switch #5 is turned off, the first antenna array subset of the first group of antenna arrays of the panel #1 is connected to the other end of the switch #1, and the first antenna array subset of the second group of antenna arrays of the panel #1 is connected to the other end of the switch # 3; when the switch #5 is closed, the first antenna array subset of the first group of antenna arrays of the panel #1 and the first antenna array subset of the second group of antenna arrays of the panel #1 are both connected with one end of the combiner #1, and the other end of the combiner #1 is connected with the other end of the switch # 1. When the switch #6 is turned off, the second antenna array subset of the first group of antenna arrays of the panel #1 is connected with the other end of the switch #2, the second antenna array subset of the second group of antenna arrays of the panel #1 is connected with the other end of the switch #4, when the switch #6 is turned on, the second antenna array subset of the first group of antenna arrays of the panel #1 and the second antenna array subset of the second group of antenna arrays of the panel #1 are both connected with one end of the combiner #2, and the other end of the combiner #2 is connected with the other end of the switch #2. Similarly, when switch #7 is turned off, the first antenna array subset of the first group antenna array of panel #2 is connected to the other end of switch #1, the first antenna array subset of the second group antenna array of panel #2 is connected to the other end of switch #3, and when switch #7 is turned on, the first antenna array subset of the first group antenna array of panel #2 and the first antenna array subset of the second group antenna array of panel #2 are both connected to one end of combiner #3, and the other end of combiner #3 is connected to the other end of switch # 3.

It will be appreciated that the connection manner of the third panel may refer to the connection manner of the two panels as shown, and will not be described herein.
It should be understood that the three structures shown in fig. 5 depict only important devices and do not depict all of the device's construction. For example, PS is not shown in both structure #1 and structure #2, and does not indicate that PS is not present, but PS connection is omitted for more clearly showing the difference between the three structures, and for PS connection, reference may be made to fig. 5A and the description in fig. 5A, and details are not repeated here. In fig. 5, the number of panels, the number of antenna elements, and the number of AD/DA are examples, and are not limited in any way.
Values of the first to third parameters in the single panel operation state and in the multi-panel operation state of the terminal device are specifically described below in connection with the configuration #0 of fig. 5A. By way of example, when operating on a single panel with structure #0, both AD/DA#1 and AD/DA#2 are in communication with the panel on the left; when the device is operated on the multi-panel, AD/DA#1 communicates with the left panel, and AD/DA#2 communicates with the right panel. When operating on a single panel, the single panel is in communication with both AD/DA, so that the number of channels corresponding to the single panel is 2 (i.e., the value of the first parameter); in addition, since one channel is connected with 4 antenna elements, it is assumed that the power of the received signal corresponding to the 4 first antenna elements or the 4 second antenna elements is P1 (P > 0), and 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 signal received by the single panel is the product of the number of channels corresponding to the single panel and the power of the signal received by each channel, that is, the power of the signal received by the single panel is 2×p1 (i.e., the value of the third parameter).
Similarly, when working on a multi-panel (2 panels), each working panel can only be communicated with one AD/DA, so that the number of channels corresponding to each working panel is 1; in addition, since the number of antenna elements connected by each AD/DA (i.e. each channel) is unchanged, the received power of each channel is still P1; in addition, each panel corresponds to only one channel, and the received power of each digital channel is P1, so the power of the received signal of each panel is 1×p1.
As an example, when structure #1 of fig. 5B is operated on a single panel, each of AD/DA #1 to AD/DA #4 communicates with the panel on the left, or each of AD/DA #1 and AD/DA #2 communicates with the panel on the left; when the multi-panel operation is performed, the AD/DA#1 and the AD/DA#2 are communicated with the left panel, and the AD/DA#3 and the AD/DA#4 are communicated with the right panel. When the structure #2 of fig. 5C is operated on a single panel, the switch #5 and the switch #6 are turned off, and the AD/DA #1 to AD/DA #4 are connected to the panel on the left; when the device works on a multi-panel, the switch #5, the switch #6, the switch #7 and the switch #8 are all closed, the AD/DA #1 and the AD/DA #2 are all communicated with the left panel, and the AD/DA #3 and the AD/DA #4 are connected to the right panel, so that under the connection mode, the values of the first parameter, the second parameter and the third parameter are shown in the table 3 under the condition that the structure #1 and the structure #2 work on a single panel and the multi-panel, and are not repeated herein. 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 both P2 and P3 are greater than 0.
TABLE 3 Table 3
It should be noted that, when the structure #1 of fig. 5B is operated on a single panel, when the AD/DA #1 to AD/DA #4 are all in communication with the left panel, since the AD/DA #1 and the AD/DA #3 are all in communication with the 4 first antenna elements of the first antenna element subset of the left panel, and the AD/DA #2 and the AD/DA #4 are all in communication with the 4 second antenna elements of the second antenna element subset of the left panel, the structure #1 is actually only corresponding to 2 different channels although being in communication with the 4 AD/DA when operated on a single panel. Therefore, in practice, when the structure #1 is operated on a single panel, only the left panel may be connected to one of the AD/DA #1 and the AD/DA #3, and to one of the AD/DA #2 and the AD/DA # 4.
In addition, as can be seen from table 3, the proposed structure #2 can receive data from 4 channels in the single panel operating state, while the structures #0 and #1 can receive data from only 2 channels in the single panel operating state. Meanwhile, the structure #0 can receive data from 1 channel in the operating state of the multi-panel, the structure #1 can receive data from 2 channels in the operating state of the multi-panel, and each panel can receive data from 2 channels in the operating state of the multi-panel, so that the reliability of the received data of the structure #2 in the operating state of the single-panel can be higher than that of the other two structures, and meanwhile, the performance of the received data of the structure #2 in the operating state of the multi-panel is not reduced compared with that of the other two structures.
It should be understood that fig. 5 only shows one possible connection structure of the first antenna structure, the second antenna structure and the third antenna structure, and in fact, there may be more possible connection manners for the above three structures, which are not described herein again.
S402, the terminal equipment sends first indication information to the network equipment. Correspondingly, the network device receives the first indication information from the terminal device.
S403, the network equipment performs data scheduling according to the first indication information.
Specifically, the network device may perform data scheduling of the better adapted terminal device according to the first indication information. For example, when the first indication information indicates that the first parameter is smaller, the network device may schedule more resources or transmit higher power for compensating for a loss caused by a smaller number of channels due to a change in the panel operating state; similarly, when the first indication information indicates that the second parameter is smaller, the network device needs to send a larger signal power to compensate the power loss caused by the change of the panel working state.
From the above, it can be seen that the performance of the terminal device in the single-panel operation state and in the multi-panel operation state using the three antenna structures is different. Therefore, the terminal equipment reports the first indication information, which is beneficial to the network equipment to schedule data according to the first indication information and improves the communication performance. This benefit is illustrated below.
As an example, taking the case where the antenna structure of the terminal device in the system includes the structure #0, the structure #1 and the 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 knows the correspondence of table 1 according to the first indication information, when the antenna structure adopted by the terminal device is the structure #0, it can be seen from table 1 that the signal receiving power (i.e., the value of the third parameter) of the operating panel of the structure #0 in the operating state of the multi-panel may be reduced. When the terminal device changes from the single-sided state to the multi-sided state, the network device performs power compensation when transmitting downlink data. Or when the terminal device is switched from the multi-panel state to the single-panel operation state, the network device performs power reduction when transmitting downlink data.
Based on the above steps S401 to S403, in an alternative embodiment, step S404 is further included: the terminal device sends second indication information to the network device, wherein the second indication information is used for indicating the panel state of the terminal device.
Specifically, the panel state may be a single-sided state, a multi-sided state, or a switch between a single-sided state and a multi-sided state. For example, the second indication information is used to indicate that the terminal device is switched from the single-panel state to the multi-panel state, or to indicate that the terminal device is switched from the multi-panel state to the single-panel state, or to indicate that the terminal device is in the multi-panel state.
It should be understood that the second indication information may be different from the first indication information, or the second indication information may be carried on the first indication information, that is, the first indication information indicates the above-mentioned correspondence relationship and the panel state of the terminal device at the same time.
As an example, in connection with S404, in a specific implementation manner, the network device considers that the terminal device is currently in the single panel operation state, and then, the network device receives, from the terminal device, first indication information and second indication information, where the first indication information is used to indicate that the value of the third parameter in the single panel operation state and in the multi-panel operation state of the terminal device is P and 2*P, respectively, or the first indication information is used to indicate that the value of the third parameter in the single panel state of the terminal device is smaller than the value of the third parameter in the multi-panel state of the terminal device, that is, the first indication information indicates that the signal receiving power of the operation panel (that is, the value of the third parameter) of the terminal device in the multi-panel operation state of the terminal device may be reduced, and the second indication information is used to indicate that the terminal device is currently in the multi-panel operation state. The network device can determine that the terminal device has changed from the single-panel operating state to the multi-panel operating state according to the second indication information, and meanwhile, the network device determines that power compensation is required when the network device sends downlink data to the terminal device when the terminal device is in the multi-panel operating state according to the first indication information.
In addition, 3 antenna structures can support multi-panel operation, that is, at least two panels can operate simultaneously at the same time. When the beam training is performed, the terminal equipment can complete the training of at least two beams at one moment (assuming that each panel is driven to emit one beam), so that the overhead of the beam training can be reduced, the system performance is further improved, and the energy consumption of the network equipment and the terminal equipment is reduced. Taking fig. 3C as an example, in step 3 of beam training, m2=3, if the terminal device can implement 3-panel operation, then the terminal device can simultaneously transmit 3 beams, and the network device uses beam #3 to detect 3 beams sent by the terminal device simultaneously, so that compared with the current process that the terminal device needs to transmit three times, each time transmits one beam, the corresponding network device receives three times, each time receives one beam, and uses beam #3 to detect each received beam, the energy consumption of the network device and the terminal device can be reduced, namely the cost of beam training is reduced, and the system performance is improved.
