Description

Communication method and related apparatus

[0001] This application claims priority to the Chinese Patent Application No. CN202411391909.4, filed on September 30, 2024, and entitled "A communication method and related apparatus", the content of which is incorporated herein by reference in its entirety. TECHNICAL FIELD

[0002] The present application relates to the field of communication, and in particular to a communication method and related apparatus. BACKGROUND

[0003] In the process of beam measurement, a base station (BS) transmits multiple beams using analog beamforming technology. A user equipment (UE) measures the transmitted beams and selects the optimal pair of transmit and receive beams for pairing.

[0004] However, as the frequency band used by the antenna of the base station increases and the aperture of the antenna expands, the Rayleigh distance corresponding to the antenna also increases. The Rayleigh distance divides the coverage area of the base station into two parts: a near-field region and a far-field region. In the near-field region within the Rayleigh distance, the phase change of the antenna array of the transmitted beam is more sensitive, and the energy of the beam is easily concentrated in a small range of space (usually a point in the near-field region). Therefore, when the UE deviates from the energy concentration point, the optimal beam determined from the existing beam scanning set does not match the UE channel information. SUMMARY

[0005] Embodiments of the present application provide a communication method and related apparatus for adjusting the energy concentration range of the beam and improving the robustness of near-field beam scanning.

[0006] In a first aspect, an embodiment of the present application provides a communication method, which is executed by a first communication device, or executed by part of components (such as a processor, a chip or a chip system, etc.) in the first communication device, or can also be implemented by a logic module or software which can realize all or part of the functions of the first communication device. In the first aspect and its possible implementation manners, the method is described by taking the example of being executed by the first communication device. In the method, the first communication device receives first information, the first information indicating a first beam, an energy concentration range of the first beam being a first range; the first communication device sends second information, the second information being used to instruct a second communication device to determine a second range; the first communication device determines and sends a plurality of second beams based on the first beam; the first communication device receives third information, the third information indicating the second range, the second range being determined by the second communication device based on the plurality of second beams, the second range being greater than the first range; and the first communication device determines a third beam based on the third information, an energy concentration range of the third beam being the second range, the third beam being used for the first communication device and the second communication device to communicate.

[0007] In the present application, each beam corresponds to a spatial domain basis vector, and each element in the spatial domain vector can represent the weight of each antenna port. Based on the weight of each antenna port represented by each element in the spatial domain vector, the signals of each antenna port are linearly superimposed to form a region with strong signals in a certain direction in space, such as a beam. In the present application, the beam can also be replaced by a basis vector, a discrete fourier transform (DFT) basis vector, a spatial domain basis vector or a beam vector.

[0008] In a possible implementation manner, the first beam is the best beam selected by the second beam when the first communication device and the second communication device perform near-field beam scanning. The near-field beam scanning can be global scanning based on an angle distance domain, can be multi-stage scanning based on an angle domain scanning and a distance domain scanning, or can be multi-stage scanning of a full space, and the specific implementation is not limited here.

[0009] In a possible implementation manner, the first beam is a beam used for the first communication device and the second communication device to currently perform communication.

[0010] In the present application, the first beam is a beam before adjustment, the second beam is a beam for measuring a coverage range, and the third beam is a beam after adjustment. The second information instructs the second communication device to start measurement of beam adjustment, and the plurality of second beams are received to determine the energy concentration range of the adjusted beam, i.e., the second range. Then the first communication device obtains the second range by receiving the third information, and determines the third beam after adjustment.

[0011] By using the above method, a beam with a variable beam width is configured, aiming to improve the robustness of the near-field beam, which can effectively prevent the frequent triggering of the beam recovery process in the near-field area, thereby reducing the overall overhead of beam management, achieving efficient use of resources and stable operation of the system.

[0012] In a possible implementation, the third information includes one or more of the following:

[0013] a relative relationship value of the plurality of signal qualities, each of the plurality of signal qualities being associated with a second beam;

[0014] a first adjustment ratio, the first adjustment ratio being associated with a ratio between the second range and the first range, or

[0015] a length of the second range or an angle corresponding to the length, and a width of the second range or an angle corresponding to the width.

[0016] In a possible implementation, the third information further includes an identifier of the received part or all of the second beams.

[0017] In a possible implementation, the relative relationship value includes a ratio and a difference.

[0018] In this application, the plurality of signal qualities are beam signal quality values of part or all of the second beams received by the second communication device, such as reference signal received power (RSRP), signal to noise ratio (SNR), and / or signal to interference plus noise ratio (SINR), etc., which are not limited here.

[0019] The first adjustment ratio can be understood as a ratio between the energy concentration range of the adjusted beam and the energy concentration range of the unadjusted beam, or a combination of the ratio and an offset. For example, the first adjustment ratio conforms to the formula y=ax+b, where y is the energy concentration range of the adjusted beam, x is the energy concentration range of the unadjusted beam, a is the ratio between them, and b is the offset, which can be a preset value or an empirical value. Alternatively, the first adjustment ratio is some mathematical deformation based on the ratio, which is not limited here.

[0020] In a possible implementation, the plurality of second beams are transmitted based on the first beam, including: determining, by the first communication device, a first area based on the first beam, the first area being a coverage range of the plurality of second beams; and transmitting, by the first communication device, the plurality of second beams based on the first area.

[0021] It can be understood that the first communication device obtains the coverage of the plurality of second beams based on the predefined angle and distance adjustment threshold, and starts the beam scanning in the local range.

[0022] In a possible implementation, the first information comprises first indication information, and the first indication information is used to request adjustment of the second range.

[0023] It can be understood that the second communication device actively requests adjustment of the beam width through the first information.

[0024] In a possible implementation, the second information is determined by one or more of the following:

[0025] The moving range of the second communication device is less than a first threshold value;

[0026] The number of beam recovery of the second communication device is greater than a second threshold value; or

[0027] The signal quality of the first beam is less than a third threshold value.

[0028] In a possible implementation, the first communication device can actively trigger adjustment of the beam width. For example, the first communication device adjusts the beam width based on the positioning information of the second communication device, if the positioning information indicates that the second communication device is in a near field area and the moving range is less than a first threshold value. For another example, the first communication device adjusts the beam width based on the beam quality of the second communication device, if the number of beam recovery of the second communication device is greater than a second threshold value.

[0029] In a possible implementation, the second notification device actively triggers adjustment of the beam width. For example, the signal quality of the optimal beam found by the second communication device through scanning is lower than a third threshold value.

[0030] In a possible implementation, the method further comprises: sending the third beam.

[0031] In a possible implementation, the method further comprises: sending a fourth beam based on the third beam, and the energy concentration range of the fourth beam is related to the second range.

[0032] Specifically, after the first communication device determines the area, the first communication device generates a fourth beam by further processing (for example, interference cancellation processing) of the third beam, and the energy concentration range of the fourth beam is related to the second range.

[0033] In a second aspect, an embodiment of the present application provides a communication method, which is executed by a second communication device, or executed by some components (for example, a processor, a chip or a chip system, etc.) in the second communication device, or can also be implemented by a logic module or software which can realize all or part of the functions of the second communication device. In the second aspect and possible implementation manners thereof, the method is taken as an example which is executed by the second communication device. In the method, the second communication device sends first information, the first information indicating a first beam, an energy concentration range of the first beam being a first range; the second communication device receives second information, the second information being used for indicating that the second communication device determines a second range; the second communication device receives a plurality of second beams, the plurality of second beams being determined by a first communication device based on the first information; the second communication device determines the second range based on the plurality of second beams, the second range being greater than the first range; and the second communication device sends third information, the third information indicating the second range.

[0034] In the present application, each beam corresponds to a spatial domain basis vector, and each element in the spatial domain vector can represent the weight of each antenna port. Based on the weight of each antenna port represented by each element in the spatial domain vector, the linear superposition of the signals of each antenna port can form a region with stronger signals in a certain direction in space, such as a beam. In the present application, the beam can also be replaced by a basis vector, a discrete fourier transform (DFT) basis vector, a spatial domain basis vector or a beam vector.

[0035] In the present application, the first beam is the beam before adjustment, the second beam is the beam for measuring the coverage range, and the third beam is the beam after adjustment. The second information indicates that the second communication device starts the measurement of beam adjustment, and receives the plurality of second beams for determining the energy concentration range of the adjusted beam, that is, the second range. Then the first communication device determines the third beam after adjustment by receiving the third information to obtain the second range.

[0036] By using the above method, a beam with a variable beam width is configured, aiming to improve the robust performance of near-field beam scanning, which can effectively prevent the frequent triggering of the beam recovery process in the near-field region, thereby reducing the overall overhead of beam management, realizing efficient use of resources and stable operation of the system.

[0037] In a possible implementation manner, the third information includes one or more of the following:

[0038] A relative relationship value of a plurality of signal qualities, each signal quality in the plurality of signal qualities being related to a second beam;

[0039] A first adjustment ratio, the first adjustment ratio being related to a ratio between the second range and the first range, or

[0040] The length of the second range or the angle corresponding to the length, and the width of the second range or the angle corresponding to the width.

[0041] In one possible implementation, the relative relationship values ​​include ratios and differences.

[0042] In this application, the multiple signal qualities are the beam signal quality values ​​of part or all of the second beam received by the second communication device, such as reference signal received power (RSRP), signal to noise ratio (SNR), and signal to interference plus noise ratio (SINR), etc., which are not specifically limited here.

[0043] The first adjustment ratio can be understood as the ratio between the energy concentration range of the adjusted beam and the energy concentration range of the beam before adjustment; it may also be a combination of this ratio and an offset. For example, the first adjustment ratio conforms to the formula y = ax + b, where y is the energy concentration range of the adjusted beam, x is the energy concentration range of the beam before adjustment, a is the ratio between them, and b is the offset, which may be a preset value or an empirical value. Alternatively, the first adjustment ratio may be some mathematical transformation based on this ratio; the specifics are not limited here.

[0044] In one possible implementation, the first information includes first indication information, which is used to request a second range.

[0045] It is understandable that the second communication device actively requests to adjust the beam width based on the first information.

[0046] In one possible implementation, the second information is determined by one or more of the following:

[0047] The movement range of the second communication device is less than the first threshold.

[0048] The number of beam recovery attempts of the second communication device is greater than the second threshold; or,

[0049] The signal quality of the first beam is less than the third threshold.

[0050] In one possible implementation, the method further includes: the second communication device receiving a third beam, the energy concentration range of the third beam being a second range, and the third beam being used for communication between the first communication device and the second communication device.

[0051] In a possible implementation, the method further includes: receiving, by the second communication device, a fourth beam, an energy concentration range of the fourth beam being related to the second range, the fourth beam being used for communication between the first communication device and the second communication device.

[0052] Specifically, the first communication device generates the fourth beam by further processing the third beam (for example, performing interference cancellation processing) after determining the region, and an energy concentration range of the fourth beam is related to the second range.

Specifically, "alignment" means that when there is an interactive message between the network device and the terminal device, the two are consistent in understanding the carrier frequency of the interactive message transmission and reception, the determination of the interactive message type, the meaning of the field information carried in the interactive message, or other configurations of the interactive message.

[0128] In addition, in other possible cases, the network device can be other devices that provide wireless communication functions for the terminal device. The embodiments of the present application do not limit the specific technology and specific device form adopted by the network device.

[0130] (3) Configuration and pre-configuration: In the present application, configuration and pre-configuration will be used simultaneously. Configuration refers to that the network device sends some parameter configuration information or parameter values to the terminal device through a message or signaling, so that the terminal device determines the communication parameters or the resources in the transmission according to the values or information. Pre-configuration is similar to configuration, which can be the parameter information or parameter values agreed by the network device and the terminal device in advance, or the parameter information or parameter values adopted by the network device or the terminal device according to the standard protocol, or the parameter information or parameter values pre-stored in the network device or the terminal device. The present application does not limit this.

[0131] Further, the values and parameters can be changed or updated.

[0132] (4) The terms "system" and "network" in the embodiments of the present application can be used interchangeably. "At least one" means one or more, and "multiple" means two or more. "And / or" describes the association relationship of the associated objects, which means that there can be three kinds of relationships, for example, A and / or B, which can represent the following cases: A exists alone, A and B exist simultaneously, and B exists alone, where A and B can be singular or plural. The character " / " generally represents an "or" relationship between the associated objects. "At least one of the following" or similar expressions means any combination of these items, including any combination of single item or multiple items. For example, "including at least one of A, B and C" can represent: including A; including B; including C; including A and B; including A and C; including B and C; including A, B and C.

[0133] It can be understood that the various numbers involved in the embodiments of the present application are only for convenient differentiation, and do not limit the scope of the embodiments of the present application. The size of the serial number of the above processes does not mean the execution order, and the execution order of the processes should be determined according to its function and inherent logic.

[0134] (5) In embodiments of the present application, "sending" and "receiving" represent the direction of signal transmission. For example, "sending information to XX" can be understood as that the destination of the information is XX, which can include direct sending through the air interface, or indirect sending through the air interface by other units or modules. "Receiving information from YY" can be understood as that the source of the information is YY, which can include direct receiving from YY through the air interface, or indirect receiving from YY through the air interface by other units or modules. "Sending" can also be understood as "output" of a chip interface, and "receiving" can also be understood as "input" of a chip interface.

[0135] In other words, sending and receiving can be between devices, such as between network devices and terminal devices, or within devices, such as between components, modules, chips, software modules or hardware modules within a device through a bus, wire or interface.

[0136] It can be understood that the information can be processed as necessary between the source and the destination of the information transmission, such as encoding and modulation, but the destination can understand the valid information from the source. Similar expressions in the present application can be similarly understood and will not be repeated here.

[0139] Referring to FIG. 1, the system architecture based on which the communication method in the embodiments of the present application is described briefly as follows.

[0140] As shown in FIG. 1, the network device 1, the network device 2, the terminal device 1, the terminal device 2, the terminal device 3, the terminal device 4, the terminal device 5, the terminal device 6, the terminal device 7, and the terminal device 8 form a communication system, in which the network device 1 can send information to one or more of the terminal devices 1 to 6. The network device 1 can also send information to the terminal device 7 or the terminal device 8 through the network device 2. In addition, the terminal device 4, the terminal device 5, and the terminal device 6 can also form a communication system, in which the terminal device 4 can send information to the terminal device 5 or the terminal device 6. The network device 2, the terminal device 7, and the terminal device 8 can also form a communication system, in which the network device 2 can send information to one or more of the terminal devices 7 and 8.

[0141] In a possible implementation, the network device adopts a hybrid beamforming method combining analog beams and digital ports to communicate with the terminal device, in view of the complexity of hardware, cost-effectiveness, and energy consumption, etc. In a multi-antenna array, analog beamforming generates beams by adjusting the phase of a shifter. To obtain the best transmission performance, the best pair of transmit and receive beams needs to be searched through beam scanning. The process of aligning the transmit and receive beams of the network device and the terminal device is called beam management.

[0142] As shown in FIG. 2, when a connection is established between a base station and a UE, taking downlink transmission as an example, it is assumed that the base station has M analog transmission beams and the UE has N analog receiving beams, and a total of MN transceiving beam pairs can be established. Generally, in high-frequency communication, the number of beam pairs is large. How to carry out effective beam measurement and reporting and reduce system overhead has become an important direction for designing large-scale antenna beam management. The downlink beam measurement process can be described as follows: if a base station can transmit M analog beams, a set of shaped reference signals can be configured for each beam direction for beam measurement, and the direction shaped by each reference signal is the same as the corresponding analog beam. The M reference signals are transmitted on different time domain and / or frequency domain resources, so that the base station can adjust the configuration of the shifter for each beam direction to realize analog beam shaping; at the same time, the UE measures the M shaped reference signals through N receiving beams respectively, and selects a suitable receiving beam. Therefore, a total of MN beam pairs need to be measured between the base station and the UE to find the best transceiving paired beam.

[0143] In the current standard protocol, analog beam shaping is based on the assumption of plane wave for beam management, each beam corresponds to a basis vector, and the common basis vector is a discrete fourier transform (DFT) basis vector. The entire cell is divided into different regions at different angles for beam measurement, so each beam is only related to angle information, and the beam shaping gain is the same in the same direction (radiation angle). It can be understood that the energy of the plane wave beam is uniform on the propagation path.

[0144] However, as the frequency band used by the antenna increases and the aperture of the antenna increases, the Rayleigh distance corresponding to the antenna also increases, and the Rayleigh distance divides the coverage range of the reference into a near-field range and a far-field range, and the user will fall into the near-field range with a high probability. Among them, the beam in the far-field range can be regarded as a plane wave, but the channel in the near-field range environment is more likely to meet the spherical wave assumption. As shown in FIG. 3, the near-field spherical wave is related to both direction (radiation angle) and distance (radiation distance), and presents a beam concentration effect in the same direction. Specifically, when the UE receives the beam energy at the energy concentration point, the beam energy is maximum, and the beam energy gradually decreases as it moves away from the energy concentration point.

[0145] Specifically, the characteristic of the far-field plane wave is that the energy distribution is uniform on the propagation path, while the near-field spherical wave has the advantage of energy concentration, but at the same time it is also a disadvantage of the spherical wave, which is more sensitive to phase.

[0146] Please refer to FIG. 4, which is an energy simulation diagram of a far-field plane wave and a near-field spherical wave in space. The y-axis and the x-axis in the figure represent the width and the length of the top view, respectively, where the base station is located at the position of y=0 and the UE is located at the position of x>0. The area outlined by the white dotted line identifies the main impact range of the main lobe of the beam, and the color brightness change in the figure reflects the simulated intensity of the beam energy. As shown in FIG. 4, the energy of the near-field spherical wave is not uniformly distributed, but is highly concentrated in the area close to the beam transmission direction, and other positions of the main lobe show a lower energy level.

[0147] Since the energy concentration range of the near-field spherical wave is small, when the UE is not in the area, the near-field beam cannot be well matched with the near-field channel environment. In addition, since the near-field spherical wave is more sensitive to phase changes, its performance is easily affected by changes in angle and distance information. Therefore, when the UE moves within a certain range of the near field, the beam switching process may be frequently triggered due to significant energy fluctuations.

[0148] Based on this, the present application provides a communication method. Please refer to FIG. 5. In FIG. 5, the first communication device and other communication devices (such as the second communication device) are taken as an example to illustrate the execution subject of the interaction, but the present application does not limit the execution subject of the interaction. For example, the communication device can be a communication equipment (such as a terminal equipment or a network equipment), or a chip, a baseband chip, a modem chip, a SoC chip (such as a SoC chip containing a modem core), a SIP chip, a communication module, a chip system, a processor, a logic module or software in the communication equipment, etc.

[0149] In the present application, when referring to a network equipment, it can refer to the network equipment itself, or a chip, a communication module, an integrated circuit, a processor, a logic module or software in the network equipment for implementing the communication method provided by the present application, and the specific implementation is not limited in the present application; when referring to a server, it can refer to the server itself, or a chip, a communication module, an integrated circuit, a processor, a logic module or software in the server for implementing the communication method provided by the present application, and the specific implementation is not limited in the present application.

[0150] As an example, the first communication device can be a network equipment, and the second communication device can be a terminal equipment.

[0151] 501. The second communication device sends first information to the first communication device; correspondingly, the first communication device receives the first information.

[0152] The first information indicates a first beam, and the energy concentration range of the first beam is a first range.

[0153] In a possible implementation, the first beam is a best beam selected by the second communication device when the first communication device and the second communication device perform near-field beam sweeping. The near-field beam sweeping can be global scanning based on an angle distance domain, multi-stage scanning based on an angle domain and a distance domain, or multi-stage scanning of a full space, and the specific implementation is not limited here.

[0154] Specifically, the second communication device is located in a near-field region of the first communication device, the first beam is a near-field beam, and the first range is an energy concentration range corresponding to the near-field beam of the first communication device.

[0155] In a possible implementation, the first beam is a beam currently used by the first communication device to communicate with the second communication device.

[0156] It can be understood that the first information is also used to instruct the first communication device to adjust the width of the communication beam. When the second communication device is in a stationary state in the near-field region, it is possible that the beam width is not adjusted. However, when the second communication device moves within a certain range of the near-field region, it may deviate from the energy concentration range of the first beam and needs to switch to other beams to obtain stable communication services. Therefore, even if the second communication device is distributed in the near-field range, it may need to determine whether the beam width needs to be adjusted according to its own situation. In addition, even if the second communication device is in a stationary state, if the best beam found by scanning cannot meet the communication requirements of the second communication device (for example, the reference signal received power (RSRP) value is lower than a threshold value), the second communication device can also consider triggering the beam width adjustment to further search for a better beam.

[0157] In a possible implementation, before step 501, the method further includes step 500:

[0158] 500. The first communication device sends a first beam to the second communication device; correspondingly, the second communication device receives the first beam.

[0159] Optionally, the first communication device sends multiple first beams to perform beam sweeping.

[0160] Optionally, the first communication device communicates with the second communication device through the first beam.

[0161] 502. The first communication device sends second information to the second communication device; correspondingly, the second communication device receives the second information.

[0162] Specifically, the second information indicates the second communication device to confirm the second range. It can be understood that the first communication device needs to feed back the specific adjustment parameter when adjusting the beam width, and the second range is the energy concentration range of the adjusted beam.

[0163] Referring to FIG. 6, FIG. 6 is a schematic diagram of a variable width beam design. A sector range with q0 as the center point is called a coordinable sphere, which is used to represent the current variable width beam energy concentration range. The range is obtained by mapping the base station array p i to any point q k on the coordinable sphere, and the base station array adjustment phase φ i is obtained, and the beam with energy concentrated in the sphere is obtained according to the phase.

[0164] Specifically, each point q k on the coordinable sphere is obtained by a function f(p i , q0, ψ′ sum (or L), θ′ sum (or W), β), where the width angle and the length angle L and W are the length and width of the central section of the coordinable sphere, β is the coordinable sphere size adjustment coefficient, and z is the base station height. The configuration of the variable width beam of the i-th antenna array is where d i,k = |q k -p i | is the distance from the i-th antenna array to the k-th mapping point. It can be understood that each antenna array is mapped to a different mapping point on the coordinable sphere, and a beam with different width is configured by the beam width W or the width angle θ′ sum (corresponding angle of width), the length L or the length angle ψ′ sum (corresponding angle of length), and the adjustment coefficient β. It can be understood that the second information indicates the second communication device to determine the required parameters in the coordinable sphere after specific adjustment.

[0165] In one possible implementation, the first communication device can actively trigger the beam width adjustment. For example, the first communication device adjusts the beam width based on the positioning information of the second communication device, if the positioning information indicates that the second communication device is in the near field area and the moving range is less than a first threshold. For another example, the first communication device adjusts the beam width based on the beam quality of the second communication device, if the number of beam recovery of the second communication device is greater than a second threshold.

[0166] In one possible implementation, the second notification device actively triggers the beam width adjustment. For example, the second communication device finds the signal quality of the optimal beam by scanning is lower than a third threshold.

[0167] 503. The first communication device sends a plurality of second beams to the second communication device; correspondingly, the second communication device receives the plurality of second beams.

[0168] Specifically, the first communication device sends a plurality of second beams according to the first beam. The first communication device sends beams in a predetermined direction and time sequence. Each beam covers a certain spatial area.

[0169] In a possible implementation, the second information includes the transmission time of the plurality of second beams, and the second communication device receives and measures the beam signals according to the transmission time.

[0170] In a possible implementation, the second communication device determines whether a received beam is a new beam according to the energy of the received beam.

[0171] The second communication device records the signal strength and quality parameters of each received beam.

[0172] In a possible implementation, the first communication device starts a local range beam sweep, constructs a new beam management set according to the beam ID of the first beam and a preset angle and distance adjustment threshold (floating threshold), and starts the beam sweep. The angle and distance adjustment threshold is intended to limit the length and width of the energy concentration range of the variable-width beam.

[0173] 504. The second communication device determines a second range based on the plurality of second beams.

[0174] Specifically, the second communication device performs signal quality evaluation on each received second beam, and the evaluation indexes include a beam signal quality value, a beam radiation angle, and a beam radiation distance, etc. The beam signal quality value can be one or more of the following: RSRP, SNR, or SINR. Based on the measurement results, the second range, i.e., the energy concentration range after beam width adjustment, is determined.

[0175] 505. The second communication device sends third information to the first communication device; correspondingly, the first communication device receives the third information.

[0176] The third information indicates the second range.

[0177] Optionally, the third information includes a plurality of signal quality relative relationship values (such as a ratio or a difference), and the plurality of signal quality values are beam signal quality values (such as RSRP, SNR, and / or SINR) of part or all of the second beams received by the second communication device.

[0178] Optionally, the third information comprises a first adjustment ratio, the first adjustment ratio being a ratio between the second range and the first range. It can be understood that the ratio between the energy concentration range of the adjusted beam and the energy concentration range of the unadjusted beam.

[0179] In the present application, the first adjustment ratio can be understood as a ratio between the energy concentration range of the adjusted beam and the energy concentration range of the unadjusted beam, or a combination of the ratio and an offset. For example, the first adjustment ratio conforms to the formula y=ax+b, where y is the energy concentration range of the adjusted beam, x is the energy concentration range of the unadjusted beam, a is the ratio, and b is the offset, which can be a preset value or an empirical value. Alternatively, the first adjustment ratio is some mathematical deformation based on the ratio, which is not limited here.

[0180] Optionally, the third information comprises a length L or a length angle of the second range, and a width W or a width angle of the second range.

[0181] Optionally, the third information comprises an identifier of part or all of the second beam received by the second communication device.

[0182] 506. The first communication device determines a third beam based on the third information.

[0183] Specifically, the energy concentration range of the third beam is the second range, and the third beam is used for communication between the first communication device and the second communication device.

[0184] 507. The first communication device sends the third beam to the second communication device; correspondingly, the second communication device receives the third beam.

[0185] Specifically, the first communication device adjusts the amplitude and phase of the basis vector based on the third information, and allocates appropriate frequency domain, time slot and other wireless resources for the third beam, and sends the third beam to the second communication device.

[0186] In a possible implementation, after determining the second range, the first communication device generates and sends a fourth beam by further processing (such as interference cancellation processing) the third beam, and the energy concentration range of the fourth beam is related to the second range.

[0187] By using the above method, a beam with variable beam width is configured, aiming to improve the robust performance of the near-field beam, which can effectively prevent frequent triggering of the beam recovery process in the near-field region, thereby reducing the overall overhead of beam management, achieving efficient use of resources and stable operation of the system.
