Description

Technical Field

[0001] This application relates to the field of communication technology, and in particular to a communication method and related apparatus. Background Technology

[0002] Measurement is crucial for signal quality detection and handover in mobile communications. The measurement process in mobile communications consists of measurement configuration and measurement reporting. Network devices configure the metrics and types to be measured, such as the measurement cycle and trigger thresholds. Terminal devices perform measurements according to the parameters configured by the network device and report the results to the network device when reporting conditions are met. Based on these reports, the network device can then make decisions regarding subsequent redirection, reselection, or handover.

[0003] Currently, for event-triggered measurements, the measurement report mainly includes: information on reference signal receiving power (RSRP) and / or information on reference signal received quality (RSRQ).

[0004] However, the information from RSRP and / or RSRQ is no longer sufficient to meet the requirements of future sensory integration scenarios, and further research is needed. Summary of the Invention

[0005] This application provides a communication method and related apparatus that can achieve the reporting of perceived quality in a specified area through interactive measurement reports.

[0006] The first aspect of this application provides a communication method that can be applied to a terminal side, such as a terminal or a communication module within a terminal, or a circuit or chip (e.g., a modem chip, also known as a baseband chip, or a system-on-a-chip (SoC) chip or system-in-package (SIP) chip containing a modem core) responsible for communication and / or sensing functions within the terminal. Alternatively, the method can be implemented by a logic module or software capable of implementing all or part of the terminal's functions, or it can be implemented through a combination of software and hardware. In the first aspect and its possible implementations, the method is described using an example of execution by a terminal device. In this method, the terminal device receives first information indicating a sensing area; the terminal device sends a measurement report including a first sensing quality of the sensing area. The first sensing quality includes at least one of a sensing resolution index and a sensing accuracy index, whereby the sensing resolution index indicates the sensing resolution and the sensing accuracy index indicates the sensing accuracy. For example, a higher sensing resolution index indicates better sensing resolution performance. Similarly, a higher sensing accuracy index indicates better sensing accuracy performance. Among them, the perceptual resolution index and / or perceptual accuracy index can represent the synesthetic performance.

[0007] Based on the above scheme, the terminal device and the network device transmit the first perception quality of the sensing area by exchanging first information and measurement reports. This first perception quality includes at least one of a perception resolution index and a perception accuracy index. That is, compared to the reference signal receiving power (RSRP) and / or reference signal received quality (RSRQ) included in the measurement reports of the prior art, the measurement report in this application includes the perception quality of the sensing area (or can be understood as a specified area), meaning that the perception quality of a specified area can be reported through the exchange of measurement reports.

[0008] Optionally, in one possible implementation of the first aspect, the aforementioned first information is further used to indicate a first resolution parameter, which is used to determine the first perceived quality.

[0009] The resolution parameter can be at the cell level or the network device level. For example, one cell corresponds to one resolution parameter. Or, one network device corresponds to one resolution parameter.

[0010] In this possible implementation, the terminal device can determine the first perceived quality through the resolution parameters sent by the network device.

[0011] Optionally, in one possible implementation of the first aspect, the first resolution parameter mentioned above includes one or more of the following: range resolution parameter, azimuth resolution parameter, or pitch resolution parameter.

[0012] In this possible implementation, the resolution parameter is represented in at least one dimension of distance, orientation, or pitch, thereby allowing the synesthetic performance to be analyzed from different dimensions.

[0013] Optionally, in one possible implementation of the first aspect, the first resolution parameter mentioned above includes: azimuth resolution parameter and / or pitch resolution parameter; the terminal device may also determine the first perception quality based on the second information; the second information includes: the location of the terminal device, the location of the first network device, the first resolution parameter, and the perception area.

[0014] In this possible implementation, when the network device has difficulty (or cannot) determine the location of the terminal device, or cannot obtain the perceived location of the terminal device in a timely manner, the terminal device can determine the first perception quality (e.g., the resolution parameter of the distance dimension) based on the second information, thereby improving the availability and / or timeliness of the distance-dimensional resolution parameter acquisition. This is particularly relevant when frequent movement of the terminal device makes it difficult for the network device to determine its accurate location, or when the network device cannot perceive the terminal device's location in a timely manner. In such cases, the resolution parameter of the distance dimension can be calculated by the terminal device itself, thereby improving the timeliness of the resolution parameter.

[0015] Optionally, in one possible implementation of the first aspect, the first information indicates a plurality of first resolution parameters, and each of the plurality of first resolution parameters is associated with a cell identifier.

[0016] In this possible implementation, when there are many resolution parameters, they can be associated through cell identifiers, which makes it easier to distinguish the resolution parameters related to different cells.

[0017] Optionally, in one possible implementation of the first aspect, the first perception quality mentioned above is related to the first cell, and the measurement report also includes a second perception quality of the perception area, which is related to the second cell, and the second cell and the first cell are adjacent cells.

[0018] In this possible implementation, the terminal device can not only measure the perceived quality of the first cell, but also the perceived quality of its neighboring cells. This makes the measurement report more comprehensive, providing a more suitable reference for network devices to perform cell redirection, reselection, or handover.

[0019] Optionally, in one possible implementation of the first aspect, the aforementioned terminal device may further acquire a second resolution parameter of the second cell, the second resolution parameter being used to determine the second sensing quality.

[0020] In this possible implementation, the terminal device can not only measure the perceived quality of the first cell, but also the perceived quality of its neighboring cells (i.e., the second cell). This allows the measurement report to provide sufficient dimensional reference for network devices to perform redirection, cell reselection, or cell handover.

[0021] Optionally, in one possible implementation of the first aspect, the first cell is the serving cell of the terminal device, the second cell is a neighboring cell, and the neighboring cell is a cell adjacent to the serving cell; or the first cell is a neighboring cell, and the second cell is the serving cell.

[0022] This possible implementation explains the possibilities of the first cell and the second cell, thus it can be applied to different measurement event reporting scenarios and / or handover scenarios.

[0023] Optionally, in one possible implementation of the first aspect, the aforementioned first information is further used to configure parameters of the event, the event being used to determine whether to send a measurement report, and the parameters include one or more of the following: the type of the event, one or more thresholds corresponding to the event, the trigger amount of the event, and the reporting amount of the event.

[0024] In this possible implementation, the terminal device can also determine the parameters of the event through the first information, thereby facilitating the terminal device to clearly define the measurement and reporting of the event.

[0025] Optionally, in one possible implementation of the first aspect, the aforementioned triggering quantities include: the perceptual resolution index and / or the perceptual accuracy index.

[0026] In this possible implementation, by defining a new sensing trigger quantity to replace the existing signal quality, a reference can be provided for network devices to perform redirection, reselection, or cell handover from a sensing perspective.

[0027] Optionally, in one possible implementation of the first aspect, the events described above include one or more of the following:

[0028] The perceived quality of the serving cell is greater than or equal to the first threshold;

[0029] The perceived quality of the serving cell is less than or equal to the second threshold;

[0030] The difference between the perceived quality of the neighboring cell and the perceived quality of the serving cell is greater than or equal to the third threshold.

[0031] The perceived quality of neighboring cells is greater than or equal to the fourth threshold;

[0032] The perceived quality of the serving cell is less than or equal to the fifth threshold, and the perceived quality of the neighboring cells is greater than or equal to the sixth threshold.

[0033] In this possible implementation, defining multiple events for the newly introduced perceived quality can make the terminal device more explicit in the measurement and reporting of events.

[0034] Alternatively, in one possible implementation of the first aspect, the aforementioned measurement report is used for switching decisions.

[0035] In this possible implementation, the measurement report reported by the terminal device can be used for the handover decision of the network device, thereby improving the sensing performance after the handover.

[0036] Alternatively, in one possible implementation of the first aspect, the aforementioned first perceived quality is related to the first cell.

[0037] In this possible implementation, the first sensing quality is the sensing quality of the first cell, or it can be understood as: the first sensing quality is calculated based on the relevant parameters of the first cell. Therefore, the first sensing quality can characterize the sensing performance of the first cell.

In this second aspect and its possible implementations, the method is described as being executed by a network device. In this method, the network device sends first information indicating a sensing area. After sending the first information, it receives a measurement report including a first sensing quality of the sensing area. The first sensing quality includes at least one of a sensing resolution index and a sensing accuracy index, whereby the sensing resolution index represents the sensing resolution and the sensing accuracy index represents the sensing accuracy.

[0039] Based on the above scheme, the terminal device and the network device exchange first information and measurement reports to transmit the first perception quality of the perception area, and the first perception quality includes at least one of perception resolution index and perception accuracy index. That is, compared with the signal quality and signal power included in the measurement report in the prior art, the measurement report in this application includes cell-related perception quality, which limits the measurement report from the perception perspective, so that the measurement report can provide a reference for the network device to perform redirection, reselection or handover of cells, etc.

[0051] This possible implementation explains the possibilities of the first cell and the second cell, thus it can be applied to different measurement event reporting scenarios and / or handover scenarios.

[0052] Optionally, in one possible implementation of the second aspect, the first information mentioned above is also used to configure parameters of the event, which is used to determine whether to send a measurement report. The parameters include one or more of the following: the type of the event, one or more thresholds corresponding to the event, the trigger amount of the event, and the reporting amount of the event.

[0053] In this possible implementation, the network device can configure the parameters of the event for the terminal device through the first information, thereby making it easier for the terminal device to clearly define the measurement and reporting of the event.

[0147] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings.

[0148] First, some terms used in the embodiments of this application will be explained to facilitate understanding by those skilled in the art.

[0149] 1. Configuration and Pre-configuration: This application uses both configuration and pre-configuration. Configuration refers to the network device / server sending configuration information or parameter values ​​to the terminal via messages or signaling, so that the terminal can determine communication parameters or transmission resources based on these values ​​or information. Pre-configuration is similar to configuration; it can be parameter information or parameter values ​​pre-negotiated between the network device / server and the terminal device, parameter information or parameter values ​​specified by standard protocols for use by the base station / network device or terminal device, or parameter information or parameter values ​​pre-stored in the base station / server or terminal device. This application does not limit this.

[0150] Furthermore, these values ​​and parameters can be changed or updated.

[0151] 2. In this application, "for indicating" can include both direct and indirect indication. When describing an indication information as indicating A, it can be understood that the indication information carries A, directly indicates A, or indirectly indicates A.

[0152] In this application, the information indicated by the instruction information is called the information to be instructed. In specific implementation, there are many ways to instruct the information to be instructed. For example, it can be implemented through direct instruction, such as through the information to be instructed itself or its index. It can also be implemented indirectly by instructing other information, where there is a relationship between the other information and the information to be instructed. Alternatively, only a part of the information to be instructed can be indicated, while the other parts are known or pre-agreed upon. For example, the instruction of specific information can be achieved by using a pre-agreed (e.g., protocol-defined) arrangement of various pieces of information, thereby reducing instruction overhead to some extent.

[0153] The information to be instructed can be sent as a whole or divided into multiple sub-information messages, and the sending period and / or timing of these sub-information messages can be the same or different. This application does not limit the specific sending method. The sending period and / or timing of these sub-information messages can be predefined, for example, according to a protocol, or configured by the transmitting device by sending configuration information to the receiving device. This configuration information can include, for example, but not limited to, one or a combination of at least two of radio resource control (RRC) signaling, medium access control (MAC) layer signaling, and physical layer signaling. MAC layer signaling includes, for example, MAC layer control elements (CE); physical layer signaling includes, for example, downlink control information (DCI), uplink control information (UCI), sidelink control information (SCI), etc.

[0154] 3. In the embodiments of this application, "sending" and "receiving" indicate the direction of signal transmission. In this application, entity A sends information to entity B, either directly to B or indirectly through other entities. Similarly, entity B receives information from entity A, either directly or indirectly through other entities. Entities A and B can be radio access network (RAN) nodes or terminals, or modules within RAN nodes or terminals. Information sending and receiving can be information interaction between RAN nodes and terminals, such as information interaction between a base station and a terminal; information sending and receiving can also be information interaction between two RAN nodes, such as information interaction between a central unit (CU) and a distributed unit (DU); information sending and receiving can also be information interaction between different modules within a device, such as information interaction between a terminal chip and other modules of the terminal, or information interaction between a base station chip and other modules in the base station. "Sending" can also be understood as the "output" of the chip interface, such as the baseband chip outputting information to the radio frequency chip, and "receiving" can also be understood as the "input" of the chip interface; for example, "sending" can also be understood as the baseband part inside the device outputting information to the radio frequency part, and "receiving" can also be understood as the radio frequency part inside the device receiving the information output by the baseband part.

[0155] 4. The terms "system" and "network" in the embodiments of this application can be used interchangeably. "At least one" means one or more, and "more than one" means two or more. "And / or" describes the relationship between related objects, indicating that there can be three relationships. For example, A and / or B can mean: A exists alone, A and B exist simultaneously, or B exists alone, where A and B can be singular or plural. The character " / " generally indicates that the related objects before and after are in an "or" relationship. "At least one of the following" or similar expressions refer to any combination of these items, including any combination of single or plural items. For example, "at least one of A, B and C" includes A, B, C, AB, AC, BC or ABC. And, unless otherwise specified, the ordinal numbers such as "first" and "second" mentioned in the embodiments of this application are used to distinguish multiple objects and are not used to limit the order, sequence, priority or importance of multiple objects.

[0156] 5. Integrated Sensing and Communication (ISAC)

[0157] Communication and sensing integration can also be simply referred to as communication and sensing integration or communication and sensing. ISAC can be simply understood as the fusion of communication and sensing.

[0158] Among them, integrated communication and sensing technology will utilize wireless communication signals to achieve sensing functions such as target detection, positioning, identification, and imaging, thereby acquiring and reconstructing surrounding environmental information and propelling future communication networks into a digital twin era that merges the physical and digital worlds. The International Telecommunication Union (ITU) report on future technology trends points out that integrated communication and sensing technology will become one of the most promising key technology directions for next-generation mobile communication systems.

[0159] 6. Perception

[0160] Wireless sensing, also known as electromagnetic sensing, refers to the process of emitting electromagnetic energy into space and then calculating information about objects by receiving the reflected electromagnetic waves. This includes parameters such as position, direction, height, speed, size, and trajectory, as well as detecting the object's internal and external shape and structure. By exploring the transmission, echo, reflection, and scattering of radio waves, we can perceive and better understand the physical world. As an electromagnetic wave sensing technology, wireless sensing technology, due to its penetrability and security, can serve as an important alternative technology for security inspection, concealed object detection, environmental reconstruction, and monitoring.

[0161] Sensing can be further categorized into several types: single-base sensing, dual-base sensing, and multi-base sensing. Single-base sensing can also be called monostation sensing, dual-base sensing can also be called bistation sensing, and multi-base sensing can also be called multistation sensing.

[0162] Single-site sensing refers to a system where the transmitting device for the sensing signal and the receiving device for the echo signal are the same device. In other words, in single-site sensing, the transmitting device must both transmit the sensing signal and receive the echo signal reflected from the surface of the sensing target. Therefore, this single-site sensing can also be called a self-transmitting and self-receiving mode, without any restrictions.

[0163] Dual-station sensing refers to a system where the transmitting device for the sensing signal and the receiving device for the echo signal are two different devices. In other words, sensing station A transmits a sensing signal, and the echo signal reflected from the surface of the sensing target is received by sensing station B. Therefore, this dual-station sensing can also be called the A-transmit, B-receive mode. It should be noted that the echo signal is obtained after the sensing signal has passed through the sensing target (e.g., reflection, diffraction, or scattering), therefore, this echo signal can still be called the sensing signal.

[0164] Multi-station sensing refers to the joint operation of multiple devices in transmitting and receiving sensing signals. Specifically, multi-station sensing can be further divided into single-transmitter-multiple-receiver, multiple-transmitter-single-receiver, and multiple-transmitter-multiple-receiver scenarios. For example, in one possible scenario, sensing station A transmits a sensing signal, which, after passing through a sensing target, generates an echo signal, which is received by sensing stations B1 and B2. In another possible scenario, sensing stations A1 and A2 transmit sensing signals simultaneously or sequentially, which, after passing through a target, generate an echo signal, which is received by sensing station B. Yet another possible scenario, sensing stations A1 and A2 transmit sensing signals simultaneously or sequentially, which, after passing through a target, generate an echo signal, which is received by sensing stations B1 and B2. A special case is where multi-station sensing is achieved through multiple single-station sensing operations. For example, in a system, sensing station A performs single-station sensing, and sensing station B also performs single-station sensing; the final sensing results are then fused. Multi-station sensing can take many forms, and this application does not limit it.

[0165] 7. Lateral resolution, azimuth resolution, pitch resolution, and angle resolution

[0166] Angular resolution describes the ability of a sensing node to resolve targets at different angles. Angular resolution is determined by the array specifications of the antenna array equipped with the sensing node. For example, an antenna array with an element spacing of half a wavelength and a total of 10 elements has an angular resolution of approximately 10°. When the sensing node is equipped with a two-dimensional array, such as a cross-shaped linear array or a two-dimensional planar array, the sensing node will have two-dimensional angular resolution capability, meaning the sensing node has corresponding angular resolutions in both directions. Typically, the angular resolution in the horizontal direction is called the azimuth angular resolution, and the angular resolution in the elevation direction is called the elevation angular resolution.

[0167] For a specific sensing area, the spatial resolution of a sensing node within that area can be calculated based on its angular resolution capabilities (e.g., azimuth and / or pitch resolution). Unlike angular resolution, spatial resolution describes a sensing node's ability to distinguish targets at different spatial locations. For example, given the azimuth resolution of a sensing node, combined with the distance from the sensing area to the node, the spatial resolution capability of the node for targets at different azimuthal positions within that sensing area can be calculated; this is the azimuth resolution. Similarly, given the pitch resolution of a sensing node, combined with the distance from the sensing area to the node, the spatial resolution capability of the node for targets at different pitch positions within that sensing area can be calculated; this is the pitch resolution. Generally, for the same angular resolution, the farther the sensing area is from the sensing node, the worse the corresponding spatial resolution.

[0168] If a sensing node has the ability to distinguish targets at different distances, it is said that the sensing node has range resolution or range-direction resolution. Range resolution is also called radial range resolution or radial resolution. At the same time, if the sensing node also has azimuth resolution and / or pitch resolution, then azimuth resolution and / or pitch resolution are collectively referred to as lateral resolution.

[0169] 8. Resolution parameters

[0170] In this application, the resolution parameter can also be described as a resolution vector, etc.

[0171] Resolution vectors can include the following various representations:

[0172] The first representation: The resolution vector can be a vector formed by projecting the spatial resolution of the sensing node in each dimension (such as range, azimuth, and pitch) onto the coordinate axes of a global coordinate system, containing the length and direction information of the vector. It can also be understood that the resolution vector (i.e., the resolution parameter) can contain at least one of the following: range resolution vector (i.e., range resolution parameter), azimuth resolution vector (i.e., azimuth resolution parameter), or pitch resolution vector (i.e., pitch resolution parameter). The following example will illustrate this in detail:

[0173] For example, a sensing node with two-dimensional resolution capabilities possesses both range resolution and lateral resolution. Range resolution, also called radial range resolution, is typically provided by a broadband signal; while lateral resolution is usually provided by an array antenna. When the array antenna provides azimuth resolution, the lateral resolution corresponds to the azimuth resolution; when the array antenna provides elevation resolution, the lateral resolution corresponds to the elevation resolution.

[0174] The direction of the range resolution vector is the gradient direction of the distance to the target perceived by the sensing node in two-dimensional space. The length of the range resolution vector is the value of the range resolution. Therefore, each component of the range resolution vector is a projection of the range resolution vector along the x-axis and y-axis of the global coordinate system.

[0175] The direction of the lateral resolution vector is the gradient direction of the azimuth or pitch angle of the sensing node when sensing the target in two-dimensional space. The length of the lateral resolution vector is the value of the lateral resolution. Therefore, each component of the lateral resolution vector is a projection of the lateral resolution vector along the x-axis and y-axis of the global coordinate system.

[0176] like Figure 1The diagram illustrates the range resolution Δr and lateral resolution Δa of a sensing node within its sensing region. Correspondingly, the range resolution vector can be represented as Δr = [Δr...]. x ,Δr y The horizontal resolution vector can be represented as Δa = [Δa] x ,Δa y ]. Δr x and Δr y Let Δa and Δr represent the components of the range resolution vector Δr along the x-axis and y-axis, respectively. x and Δa y These represent the components of the lateral resolution vector Δa along the x-axis and y-axis, respectively. Bold symbols indicate vectors, while non-bold symbols indicate numerical values, such as the vector length. The distance resolution vector and the lateral resolution vector together determine the two-dimensional resolution unit.

[0177] Similarly, for a sensing node with three-dimensional resolution capability, its resolution capability includes range resolution, azimuth resolution, and pitch resolution. Likewise, the resolution vector can include a range resolution vector, an azimuth resolution vector, and a pitch resolution vector. These three vectors are respectively represented as the range resolution vector Δr = [Δr...]. x ,Δr y ,Δr z ], azimuth resolution vector Δa=[Δa x ,Δa y ,Δa z ], pitch resolution vector Δe=[Δe x ,Δe y ,Δe z The aforementioned three factors together determine the three-dimensional resolution unit. Wherein, Δr x , Δr y and Δr z These represent the components of the range resolution vector Δr along the x-axis, y-axis, and z-axis, respectively. Δa x , Δa y and Δa z These represent the components of the azimuth resolution vector Δa along the x-axis, y-axis, and z-axis, respectively. Δe x Δe y and Δe z These represent the components of the pitch resolution vector Δe on the x-axis, y-axis, and z-axis, respectively.

[0178] The second representation: the transformation matrix corresponding to the resolution unit, or the eigenvalues ​​and eigenvectors of the transformation matrix corresponding to the resolution unit. Detailed explanation follows:

[0179] The size of a resolution unit can be defined as the size of the region enclosed by a closed contour line or contour surface in the amplitude response of the target in the perception result. For two-dimensional perception, the resolution unit is the region enclosed by the contour line; for three-dimensional perception, the resolution unit is the region enclosed by the contour surface. The amplitude value at any point on the contour line or contour surface is the peak value of the target's amplitude response minus N decibels (dB), where N is an integer or decimal greater than 0. For example, N can be 1, 2, 3, 3.1, 3.2, 4, etc., and is not limited here. For ease of description, 3 will be used as an example below.

[0180] In this context, the target's amplitude response along each resolution vector direction typically follows a sinc function. For example, in 2D perception, the target's amplitude response along the range direction conforms to a sinc function, and the target's amplitude response along the lateral direction conforms to a sinc function. In 3D perception, the target's amplitude response along the range direction conforms to a sinc function, the target's amplitude response along the azimuth direction conforms to a sinc function, and the target's amplitude response along the pitch direction conforms to a sinc function. The specific parameters of the sinc function in each direction can be different, and are specifically determined by the resolution vector in each direction.

[0181] For ease of analysis, the sinc function can be approximated using a quadratic function. Taking two-dimensional sensing as an example, assuming the sensing node has range and lateral resolution capabilities, and assuming the lateral direction is the azimuth direction, the magnitude response g(r,a) of the target in the range-azimuth domain (ra coordinate system) can be expressed as shown in the following formula:

[0182] Formula 1:

[0183] The peak value of the target's magnitude response is normalized to 1 when or At that time, g(r,a) = 0.75, meaning a power attenuation of 3dB. The target's amplitude response is defined by the closed contour line corresponding to the 3dB peak attenuation, which determines the resolution unit. This closed contour line f(r,a) can be expressed as shown in the following formula:

[0184] Formula 2:

[0185] It can be seen that the closed contour line is an elliptic curve in the ra coordinate system, that is, the resolution unit is an ellipse.

[0186] The expression for the closed contour line f(r,a)=1 shown in Formula 2 above can be represented by matrices and vectors as follows: Formula 3

[0187] Formula 3:

[0188] Furthermore, based on the resolution vector Δr=[Δr x ,Δr y ] and Δa=[Δa x ,Δa y Transforming the distance coordinate r and the azimuth coordinate a to the global xy coordinate system, we can obtain the following formula:

[0189] Formula 4:

[0190] Formula 4 above can be simplified to Formula 5 as follows:

[0191] Formula 5:

[0192] in,

[0193] It can be seen that the contour lines of the resolution cell are elliptic curves in the xy coordinate system. A is defined as the transformation matrix. Since A is a positive definite matrix, its eigenvalues ​​are decomposed to obtain the eigenvalues ​​[λ1, λ2]. Here, the resolution vector can be represented by the transformation matrix A, or by the eigenvalues ​​[λ1, λ2] and their corresponding eigenvectors.

[0194] The square root of the reciprocal of the eigenvalue is the length of the principal axis of the ellipse. Assuming λ₁ ≥ λ₂, then... It is the length of the shorter principal axis of the ellipse. This is the length of the longer principal axis of the ellipse. Therefore, the size of the resolution unit, which is also the area of ​​the ellipse, is...

[0195] For example, Figure 2 and Figure 3 An example of transforming the contour ellipse of a resolution cell from the ra coordinate system to the xy coordinate system is shown. Figure 2 In the example shown, the range resolution vector and the lateral resolution vector are orthogonal in the xy coordinate system. Therefore, after transforming from the ra coordinate system to the xy coordinate system, the shape of the contour ellipse of the resolution cell does not change; only its orientation rotates. In the xy coordinate system, the principal axis of the ellipse remains perpendicular to either the range resolution vector or the lateral resolution vector. Figure 3 In the example shown, the range resolution vector and the lateral resolution vector are not orthogonal in the xy coordinate system. Therefore, after transforming from the ra coordinate system to the xy coordinate system, the contour ellipse of the resolution cell not only rotates in direction but also changes in shape. It is important to note that the principal axis of the contour ellipse in the xy plane is no longer perpendicular to either the range resolution vector or the lateral resolution vector. Figure 3 The lengths of the two spindles were marked as follows: and

[0196] Similarly, for 3D perception, the resolution unit is an ellipsoid in the xyz coordinate system, and the size of the resolution unit is the volume of the ellipsoid. Using the aforementioned method, based on the range resolution vector, azimuth resolution vector, and pitch resolution vector, a 3x3 transformation matrix A can be obtained. Eigenvalue decomposition of this matrix yields eigenvalues ​​[λ1, λ2, λ3]. In other words, the resolution vector can be represented by the 3x3 transformation matrix A, or by the eigenvalues ​​[λ1, λ2, λ3] and their corresponding eigenvectors. The size of the resolution unit can be the volume of the ellipsoid.

[0197] The third representation: the vectors corresponding to the principal axes of the resolution ellipse or resolution ellipsoid corresponding to the resolution unit.

[0198] It is understandable that the above three representations are just examples. In practical applications, resolution vectors can also have other representations, which are not limited here.

[0199] 9. Region

[0200] The region in this application embodiment can be referred to as: sensing region, region to be sensed, region of interest (AOI), region where the target to be sensed is located, etc., and no specific limitation is made here.

[0201] Optionally, the region can refer to a specific geographical area or logical area that the user is interested in, etc., without being limited here.

[0202] For example, when a region refers to a geographical area, it can refer to a geographical entity that is shaped like a region in map data. For example, a region can refer to one or more of the following: the boundary of a residential community, the area of ​​a park or green space, a university, an office building, an industrial park, a shopping mall, a hospital, a scenic spot, or the boundary of a stadium, etc.

[0203] For example, when a region refers to a logical region, this logical region can correspond to a specific geographical region, and its shape can match the shape of its corresponding geographical region. The size of the logical region is proportional to the size of its corresponding geographical region, and the area of ​​the logical region is proportional to the area of ​​its corresponding geographical region.

[0204] The geographical region can be a certain area in the real physical world. For example, the geographical region can be represented by longitude, latitude, and altitude. For instance, the starting point could be denoted as (x0, y0, z0), and the outdoor scene could be 100m × 100m with that starting point as the reference. The geographical region can be divided into multiple logical regions in a certain way. For example, the 100m × 100m geographical region can be divided into 1m × 1m regions, resulting in 100 × 100 logical regions. Each logical region is 1m × 1m.

[0205] It should be understood that in this application, a region may have at least one of the following attributes: shape, size, area, geographical location, etc. In this application, different regions have the same shape, outline, size, radius, and area. Different regions have different geographical locations. There is no overlap between different regions.

[0206] Furthermore, the form of this area can be a two-dimensional shape or a three-dimensional shape, etc., and there is no specific limitation here.

[0207] In one possible implementation, the shape of the aforementioned region can be a regular shape or an irregular shape, without being limited here. For example, the shape of the region can be the following regular shapes: square, rectangle, trapezoid, triangle, ellipse, circle, cylinder, cone, sphere, frustum, etc.

[0208] For example, the shape of a region can be defined by a protocol or by a communication device. Region shapes defined by different communication devices can be the same or different. The same communication device can also define multiple region shapes. Similarly, the size, radius, and area of ​​a region can be defined by a protocol or by a communication device. Region sizes, radii, and areas defined by different communication devices can be the same or different. The same communication device can also define multiple region sizes, multiple region radii, or multiple region areas.

[0209] In one possible implementation, multiple regions can be indexed (e.g., numbered) to identify different regions.

[0210] The technical solution of this application can be applied to cellular communication systems related to the 3rd Generation Partnership Project (3GPP). For example, 4th generation (4G) communication systems, 5G communication systems, and communication systems beyond the 5th generation. For example, future communication systems. For example, 4th generation communication systems may include Long Term Evolution (LTE) communication systems. 5th generation communication systems may include New Radio (NR) communication systems. The technical solutions of this application can also be applied to wireless fidelity (WiFi) systems, standalone (SA) scenarios, dual connectivity (DC), macro-micro scenarios composed of base stations of different forms (e.g., scenarios where wide-coverage base stations and small-coverage base stations coexist), device-to-device (D2D), vehicle-to-everything (V2X) communication systems, non-terrestrial networks (NTN), integrated access and backhaul (IAB) communication scenarios, reconfigurable intelligent surface (RIS) communication scenarios, etc., and are not specifically limited here.

[0211] For example, please refer to Figure 4 This is a schematic diagram of the architecture of the communication system 1000 used in an embodiment of this application. Figure 4 As shown, the communication system includes a radio access network (RAN) 100 and a core network 200. Optionally, the communication system 1000 may also include an Internet 300. The RAN 100 includes at least one RAN node (e.g., ...). Figure 4 110a and 110b, collectively referred to as 110, may also include at least one terminal device (such as...). Figure 4 RAN100, denoted as RAN100, comprises RAN nodes 120a-120j, collectively referred to as RAN120. RAN100 may also include other RAN nodes, such as wireless relay equipment and / or wireless backhaul equipment. Figure 4(Not shown in the image). Terminal device 120 is wirelessly connected to RAN node 110, and RAN node 110 is wirelessly or wired connected to core network 200. The core network equipment in core network 200 and RAN node 110 in RAN 100 can be independent physical devices, or they can be the same physical device integrating the logical functions of core network equipment and RAN nodes. Terminal devices and RAN nodes can be interconnected via wired or wireless means.

[0212] RAN100 can be an evolved universal terrestrial radio access (E-UTRA) system, an NR system, or a future radio access system as defined in 3GPP. RAN100 can also include two or more of the above-mentioned different radio access systems. RAN100 can also be an open RAN (O-RAN).

[0213] RAN nodes, also known as radio access network devices, RAN entities, or access nodes, are used to help terminal devices access communication systems wirelessly. Furthermore, RAN nodes can also be called network devices, which are apparatuses deployed in a radio access network to provide wireless communication and / or sensing functions for terminal devices. Network devices can include various forms of macro base stations, micro base stations (also known as small cells), relay stations, access points, etc. The names of network devices may differ in systems employing different radio access technologies. It is understood that all or part of the functions of the access network devices in this application can also be implemented through software functions running on hardware, or through virtualization functions instantiated on a platform (e.g., a cloud platform). The embodiments of this application do not limit the specific technologies or specific device forms used in the radio access network devices.

[0214] In one application scenario, a RAN node can be a base station, an evolved NodeB (eNodeB), a transmission reception point (TRP), a next-generation NodeB (gNB) in a 5G mobile communication system, or a base station in a future mobile communication system. A RAN node can also be a macro base station (such as...). Figure 4 110a in the text), can also be a micro base station or an indoor station (such as... Figure 4The RAN node (110b) can also be a relay node or donor node, or a wireless controller in a Cloud Radio Access Network (CRAN) scenario. Of course, in future communication systems, RAN nodes may also be wearable devices or vehicle-mounted devices, etc.

[0215] In another application scenario, multiple RAN nodes can collaborate to help terminal devices achieve wireless access, with different RAN nodes implementing different functions of the base station. For example, a RAN node can be a CU, DU, or radio unit (RU). Here, the CU performs the functions of the base station's Radio Resource Control Protocol (RRCP) and Packet Data Convergence Protocol (PDCP), and can also perform the functions of the Service Data Adaptation Protocol (SDAP). The DU performs the functions of the base station's Radio Link Control (RAN) and MAC layers, and can also perform some or all of the physical layer functions. For specific descriptions of these protocol layers, refer to the relevant 3GPP technical specifications. The RU can be used to implement radio frequency signal transmission and reception. The CU and DU can be two independent RAN nodes or integrated into the same RAN node, such as within a baseband unit (BBU). RUs can be included in radio frequency equipment, such as in a remote radio unit (RRU) or an active antenna unit (AAU). CUs can be further divided into two types of RAN nodes: CU-control plane and CU-user plane.

[0216] In different systems, RAN nodes may have different names. For example, in an O-RAN system, a CU can be called an open CU (O-CU), a DU can be called an open DU (O-DU), and an RU can be called an open RU (O-RU). The RAN nodes in the embodiments of this application can be implemented through software modules, hardware modules, or a combination of software and hardware modules. For example, a RAN node can be a server loaded with the corresponding software modules. The embodiments of this application do not limit the specific technology or device form used in the RAN nodes.

[0217] A terminal device is a device with wireless transceiver capabilities, capable of sending signals to or receiving signals from RAN nodes. Terminal devices can also be called user equipment (UE), mobile stations, mobile terminal devices, etc. They can be widely used in various scenarios, such as wireless fidelity (WiFi) systems, device-to-device (D2D) communication, vehicle-to-everything (V2X) communication, machine-type communication (MTC), the Internet of Things (IoT), virtual reality (VR), augmented reality (AR), industrial control, autonomous driving, telemedicine, smart grids, smart furniture, smart offices, smart wearables, intelligent transportation, and smart cities. Terminal devices can be mobile phones, tablets, computers with wireless transceiver capabilities, wearable devices, vehicles, 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 terminal devices.

[0218] For example, a terminal device is a wearable device. Wearable devices, also known as wearable smart devices or smart wearable devices, are a general term for devices that utilize wearable technology to intelligently design and develop everyday wearables, such as glasses, gloves, watches, clothing, and shoes. Wearable devices are portable devices that are worn directly on the body or integrated into the user's clothing or accessories. Wearable devices are not just hardware devices, but also achieve powerful functions through software support, data interaction, and cloud interaction. Broadly speaking, wearable smart devices include those that are feature-rich, large in size, and can achieve complete or partial functions without relying on a smartphone, such as smartwatches or smart glasses, as well as those that focus on only one type of application function and need to be used in conjunction with other devices such as smartphones, such as various smart bracelets, smart helmets, and smart jewelry.

[0219] For ease of description, Figure 4 The illustrated communication system is described using a base station as an example of an access network device. It is understood that when the communication system includes an IAB network, the base station can be an IAB node. It should be noted that in the embodiments of this application, the base station and the access network device can be interchanged.

[0220] Base stations and terminal equipment 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 terminal equipment.

[0221] The roles of base stations and terminal devices can be relative, for example, Figure 4 The helicopter or drone 120i can be configured as a mobile base station. For terminal devices 120j that access the wireless access network 100 via 120i, terminal device 120i is a base station; however, for base station 110a, 120i is a terminal device, 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 terminal devices can be collectively referred to as communication equipment. Figure 4 The 110a and 110b in the text can be referred to as communication devices with base station functions. Figure 4 The 120a-120j in the text can be referred to as communication equipment with terminal device functions.

[0222] Communication between base stations and terminal devices, between base stations, and between terminal devices 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.

[0223] In the embodiments of this application, the functions of the base station can be executed by modules (such as chips) within the base station, or by a control subsystem that includes base station functions. This control subsystem, including base station functions, can be a control center in the aforementioned application scenarios such as smart grids, industrial control, intelligent transportation, and smart cities. Similarly, the functions of the terminal device can be executed by modules (such as chips or modems) within the terminal device, or by a device that includes terminal device functions.

[0224] In this application, the base station sends downlink signals or downlink information to the terminal, with the downlink information carried on the downlink channel; the terminal sends uplink signals or uplink information to the base station, with the uplink information carried on the uplink channel. In order to communicate with the base station, the terminal needs to establish a radio connection on a cell controlled by the base station. The cell with which the terminal has established a radio connection is called the terminal's serving cell.

[0225] As can be understood, RAN100, as previously described, includes at least one RAN node (e.g., Figure 4 110a and 110b, collectively referred to as 110, may also include at least one terminal device (such as...). Figure 4 120a-120j in the series are collectively referred to as 120).

[0226] In one possible implementation, the communication system includes a RAN node 110 and multiple terminal devices. In this case, a single RAN node can transmit data or control signaling to one or more terminal devices.

[0227] In another possible implementation, the communication system includes multiple RAN nodes 110 and a terminal device 120. In this case, the multiple RAN nodes can also transmit data or control signaling to a single terminal device simultaneously.

[0228] In recent years, sensing technology has attracted widespread attention from the academic community. Sensing technology obtains the characteristics of the signal space, or channel, by analyzing changes in wireless signals during propagation, thereby enabling environmental perception. The environment here can include factors such as buildings and moving vehicles.

[0229] The technical solutions in this application embodiment can be applied to sensing scenarios. For example, Figure 5 A schematic diagram illustrating a possible sensing scenario to which embodiments of this application are applicable is shown. For example... Figure 5 As shown, the sensing scenario can include network devices, terminal devices, and sensing areas.

[0230] The network devices and terminal devices are described in the foregoing and will not be repeated here. Uplink and / or downlink data transmission can occur between the network devices and the terminal devices.

[0231] Furthermore, network devices and terminal devices can also perform bi-base sensing of the sensing area. For example, a network device sends a sensing signal, and the echo signal generated by the sensing signal after reflection, diffraction, or scattering in the sensing area is received by the terminal device. Similarly, a terminal device sends a sensing signal, and the echo signal generated by the sensing signal after reflection, diffraction, or scattering in the sensing area is received by the network device. Processing the echo signal yields sensing data. Sensing data may include, but is not limited to, one or more of the following: signal strength, delay, timing, angle of arrival, or other data that can be directly measured from the echo signal, or other values ​​that are functions of such measurements. Sensing data may also include descriptions and / or tags (e.g., header information) to identify the purpose and / or source of the sensing data, or to identify a target associated with the sensing data.

[0232] Understandable, Figure 5 The network devices and terminal devices shown are just examples. In practical applications, network devices or terminal devices can also be replaced by positioning reference units (PRUs), reflective intelligent surfaces (RISs), etc., without any specific limitations here.

[0233] It should be noted that, Figure 5 The number of network devices and terminal devices in the illustrated sensing scenario can be one or more, and is not limited here. Furthermore, Figure 5 The sensing scenario shown can also include a control node, which can also have sensing capabilities. Alternatively, the control node can be a core network device, such as an access and mobility function (AMF), or a location management function (LMF), sensing management function (SMF), location server (LS), distribution system (DS), etc.

[0234] The communication system and scenario architecture described in the embodiments of this application are for the purpose of more clearly illustrating the technical solutions of the embodiments of this application, and do not constitute a limitation on the technical solutions provided in the embodiments of this application. As those skilled in the art will know, with the evolution of network architecture and the emergence of new service scenarios, the technical solutions provided in the embodiments of this application are also applicable to similar technical problems.

[0235] Currently, the measurement process in mobile communication is divided into measurement control and measurement reporting. In measurement control, network equipment configures the indicators and types to be measured, such as the measurement cycle and measurement trigger thresholds. Terminal devices perform measurements according to the parameters configured by the network equipment and report them to the network equipment via measurement reports when the reporting conditions are met. The network equipment then uses these measurement reports to make subsequent decisions regarding redirection, reselection, or handover. For event-triggered measurements, the measurement report mainly includes: reference signal receiving power (RSRP) and reference signal received quality (RSRQ).

[0236] However, RSRP and RSRQ can no longer meet the requirements of future integrated sensing scenarios.

[0237] To address the aforementioned technical problems, embodiments of this application provide a communication method and related apparatus. A terminal device and a network device exchange first information and a measurement report to transmit the first perception quality of a sensing area. This first perception quality includes at least one of a perception resolution index and a perception accuracy index. That is, compared to the signal quality and signal power included in the measurement report of the prior art, the measurement report in this application includes cell-related perception quality, defining the measurement report from a perception perspective. This allows the measurement report to provide a reference for the network device to perform redirection, cell reselection, or cell handover, etc.

[0238] Please see Figure 6 This application provides a flowchart illustrating a communication method, which may include steps 601 and 602. Steps 601 and 602 can be executed by a communication device, or by some components of the communication device (e.g., processors, circuits, chips, or chip systems), or by a logic module or software capable of implementing all or part of the functions of the communication device. The following description uses execution by a communication device as an example. The processing performed by a single execution entity in steps 601 and 602 can also be divided into multiple execution entities, which can be logically and / or physically separated. For example, when the communication device is an access network device, the processing performed by the communication device can be divided into execution by at least one network element such as a CU, DU, or RU. This method can be applied to the aforementioned... Figure 4 and Figure 5 In any of the system architectures shown, the specifics are not limited here.

[0239] Due to the long intervals between the steps, steps 601 and 602 will be briefly described here first, and then described in detail later. Step 601: The network device sends the first information to the terminal device. Step 602: The terminal device sends a measurement report to the network device.

[0240] Step 601: The network device sends the first information to the terminal device. This step is optional.

[0241] Optionally, the network device sends first information to the terminal device. Correspondingly, the terminal device receives the first information sent by the network device. The terminal device can be one of the aforementioned... Figure 4 or Figure 5 The terminal equipment and network equipment mentioned above can be the aforementioned Figure 4 or Figure 5 RAN nodes or base stations, etc.

[0242] Optionally, the first information may be used to indicate one or more of the following: the sensing area, the first resolution parameter, or the parameter configuration of the event, etc., without being limited here.

[0243] For example, the first information is used to indicate the sensing area. For example, the first information is used to indicate a first resolution parameter. For example, the first information is used to indicate the parameter configuration of an event. For example, the first information is used to indicate the sensing area and the first resolution parameter. For example, the first information is used to indicate the parameter configuration of the sensing area and the event. For example, the first information is used to indicate the parameter configuration of the first resolution parameter and the event. For example, the first information is used to indicate the parameter configuration of the sensing area, the first resolution parameter, and the event.

[0244] The parameters indicated by the first piece of information are described below:

[0245] 1. The first information indicates the sensing area.

[0246] There are several ways to indicate the sensing area using the first piece of information, such as absolute coordinates of a geographical location or reference coordinates, etc. No specific method is specified here. The description of the sensing area can be found in the terminology section above, and will not be repeated here.

[0247] In this application's embodiments, the sensing area may or may not be related to the cell. Alternatively, it can be understood that the sensing area can be within or outside the cell. For example, when the sensing area is related to a cell, the first area may correspond to one or more cells. For instance, if the first area corresponds to one cell, the first information can also be understood as cell-level information.

[0248] For example, taking the first information indicating the sensing area using reference coordinates as an example, the first information can indicate an area relative to a reference point in a certain direction and at a certain distance as the sensing area. The reference point can be the location of a network device, the location of a terminal device, or the location of other objects (such as buildings, scenic spots, etc.), etc., and is not specifically limited here.

[0249] For example, if we add the perception region as a new field to the MeasObject information element (IE), the first piece of information carried in the MeasObject IE is as follows:

[0250]

[0251] As can be seen, the "sensingArea" indicator has been added to MeasObject IE to indicate the sensing area.

[0252] 2. The first information indicates the first resolution parameter.

[0253] The number of first resolution parameters indicated by the first information can be one or more, the number of events can be one or more, and the parameter configuration of the events can be one or more; no specific limitation is made here.

[0254] Furthermore, the first information can also be used to indicate the second resolution parameters.

[0255] Optionally, when there are multiple resolution parameters (e.g., a first resolution parameter and / or a second resolution parameter), each of the multiple resolution parameters can be associated with a cell identifier or with a network device (e.g., a base station). For example, one cell identifier corresponds to one resolution parameter. Another example is that one cell identifier corresponds to one network device.

[0256] The cell identifier in this application embodiment may include one or more of the following: physical cell identity (PCI or PCID), evolved universal terrestrial radio access network cell identifier (E-UTRAN cell identifier, ECI), or NR cell ID (NCI), etc., without specific limitations here. For example, ECI can also be understood as a partial bit in eNodeB ID + a partial bit in cell ID, and NCI can be understood as a partial bit in gNodeB ID + a partial bit in cell ID, etc., without specific limitations here.

[0257] For example, the first resolution parameter refers to the resolution parameter of the first cell, the second resolution parameter refers to the resolution parameter of the second cell, and the first cell and the second cell are neighboring cells.

[0258] For example, the first cell is the serving cell of the terminal device, the second cell is the neighboring cell of the serving cell, the first network device is the network device in the serving cell, and the second network device is the network device in the neighboring cell.

[0259] For example, the first cell is a neighboring cell of the serving cell, the second cell is the serving cell, the first network device is the network device in the neighboring cell, and the second network device is the network device in the serving cell.

[0260] Optionally, any resolution parameter may include one or more of the following: range resolution parameter, azimuth resolution parameter, or pitch resolution parameter, etc. Alternatively, any resolution parameter may include one or more of the following: lateral resolution, angular resolution, etc. The terms and conditions for resolution and resolution parameters can be found in the preceding terminology descriptions and will not be repeated here.

[0261] In addition, the azimuth resolution parameter and the elevation resolution parameter can also be referred to as the angle measurement capability.

[0262] For example, any resolution parameter may include a range resolution parameter. Another example is that any resolution parameter may include an azimuth resolution parameter. Yet another example is that any resolution parameter may include a pitch resolution parameter. Another example is that any resolution parameter may include both a range resolution parameter and an azimuth resolution parameter. Yet another example is that any resolution parameter may include both a range resolution parameter and a pitch resolution parameter. Yet another example is that any resolution parameter may include a range resolution parameter, an azimuth resolution parameter, and a pitch resolution parameter.

[0263] It should be noted that any resolution parameter can be represented in one or more of the following forms: vector, matrix, array parameters, etc. For example, array parameters can include one or more of the following: number of rows and columns, subarray spacing, polarization, or array angle (e.g., azimuth and / or elevation). Another example is that array parameters include subarray coordinates.

[0264] Alternatively, it can be understood that any resolution parameter may include one or more of the following: the projection vector of the spatial resolution onto each coordinate axis of the global coordinate system, the vectors corresponding to each principal axis of the resolution ellipse or resolution ellipsoid of the resolution unit, the transformation matrix of the resolution unit, or the eigenvalues ​​and eigenvectors of the transformation matrix of the resolution unit.

[0265] For example, continuing with the example above where the first piece of information is carried in MeasObject IE, an example of a resolution parameter is as follows:

[0266]

[0267] As can be seen, a "resolutionVectorList" is added to MeasObject / IE to indicate the resolution parameter (e.g., the first resolution parameter), and the resolution parameter is carried through the ResolutionVectorList parameter / IE, for example:

[0268]

[0269] In the ResolutionVectorList parameter / IE, “rangeResolutionVector” indicates the range resolution parameter, “azimuthResolutionVector” indicates the azimuth resolution parameter, and “elevationResolutionVector” indicates the elevation resolution parameter.

[0270] 3. Parameter configuration for the first information indicator event.

[0271] Here, an event can also be called a measurement event. Events are used by the terminal device to determine whether to send a measurement report, or can be understood as events that trigger the terminal device to report a measurement report. The parameter configuration of an event can also be called measurement event configuration.

[0272] Optionally, the first information can be called measurement configuration information or measConfig, etc., and the specific name is not limited here. For example, step 601 can also be understood as the process by which the network device performs measurement configuration for the terminal device. For example, the first information could be an RRC reconfiguration message.

[0273] In this embodiment of the application, the parameter configuration of the event includes one or more of the following: measurement object, reporting configuration, event type, one or more thresholds corresponding to the event, event triggering amount, event reporting amount, etc., which are not specifically limited here.

[0274] The explanations for the above configurations are as follows:

[0275] (1) The measurement object can also be called the sensing object or the sensing measurement object. The measurement object can refer to at least one of the serving cell and the neighboring cell (i.e., the neighboring cell of the serving cell) of the terminal device, or it can refer to at least one of the serving base station and the neighboring base station.

[0276] (2) The reporting configuration may include at least one of event reporting and periodic reporting. Alternatively, it can be understood as the reporting configuration being used to configure the terminal device to periodically or event-triggered report of measurement reports, which is not limited here.

[0277] (3) The event type may include one or more of the following: S1, S2, S3, S4, S5. The definition or description of each event can be found in Table 1:

[0278] Table 1

[0279] Event Type Event Definition S1 The perceived quality of the serving cell is greater than or equal to the first threshold. S2 The perceived quality of the serving cell is less than or equal to the second threshold. S3 The difference between the perceived quality of the neighboring cell and the perceived quality of the serving cell is greater than or equal to the third threshold. S4 The perceived quality of neighboring cells is greater than or equal to the fourth threshold. S5 The perceived quality of the serving cell is less than or equal to the fifth threshold, and the perceived quality of the neighboring cells is greater than or equal to the sixth threshold.

[0280] An S1 event refers to a situation where the perceived quality of the serving cell is greater than or equal to a first threshold. For example, an S1 event occurs when the perceived quality of the serving cell becomes higher than the first threshold.

[0281] An S2 event occurs when the perceived quality of the serving cell is less than or equal to a second threshold. For example, an S2 event occurs when the perceived quality of the serving cell falls below the second threshold.

[0282] An S3 event occurs when the difference between the perceived quality of a neighboring cell and the perceived quality of the serving cell is greater than or equal to a third threshold. For example, an S3 event occurs when the perceived quality of a neighboring cell is higher than the perceived quality of the serving cell by the third threshold.

[0283] An S4 event is defined as a situation where the perceived quality of a neighboring cell is greater than or equal to the fourth threshold. For example, an S4 event is defined as a situation where the perceived quality of a neighboring cell becomes higher than the fourth threshold.

[0284] An S5 event occurs when the perceived quality of the serving cell is less than or equal to the fifth threshold, and the perceived quality of neighboring cells is greater than or equal to the sixth threshold. For example, an S5 event occurs when the perceived quality of the serving cell falls below the fifth threshold and the perceived quality of neighboring cells rises above the sixth threshold.

[0285] Among them, the events S1 to S5 mentioned above can be understood as events obtained by replacing the trigger values ​​of events A1 to A5. Or it can be understood as using perceived quality instead of signal quality for event judgment.

[0286] (4) One or more thresholds corresponding to an event may include one or more of the following: at least one threshold corresponding to the event type (e.g., at least one of the first threshold Thresh1, the second threshold Thresh2, the third threshold Thresh3, the fourth threshold Thresh4, the fifth threshold Thresh5, or the sixth threshold Thresh6), the result offset (Off) corresponding to the event type, the magnitude hysteresis (Hys) corresponding to the event type, the time hysteresis (TimeToTrigger) corresponding to the event type, the frequency offset (Ofs) of the serving cell, the frequency offset (Ofn) of the neighboring cell, the cell offset (CellIndividualOffset, CIO) (Ocs) of the serving cell, the CIO (Ocn) of the neighboring cell, etc.

[0287] Optionally, the one or more thresholds corresponding to an event can also be understood as one or more thresholds for the event's entry conditions, or as one or more thresholds for the event's exit conditions, or as one or more thresholds related to both entry and exit conditions. The correspondence between the various thresholds and events in this case can be found in Table 2:

[0288] Table 2

[0289]

[0290]

[0291] Where Ms represents the measurement results of the serving cell (or the perceived quality of the serving cell), and Mn represents the measurement results of the neighboring cell (or the perceived quality of the neighboring cell).

[0292] (5) The triggering quantity of an event is related to the perception quality. It can also be understood that the first information is used to configure the triggering quantity of the event to be reported (also known as perception type, measurement index, etc.).

[0293] Optionally, the triggering quantity of the event includes at least one of the sensing resolution indicator (SRI) and the sensing accuracy indicator (SAI).

[0294] SRI indicates the resolution of the sensing sensor; a higher SRI indicates better resolution performance. SAI indicates the accuracy of the sensing sensor; a higher SAI indicates better accuracy performance.

[0295] For example, the event may be triggered via SRI. Or, for example, the event may be triggered via SAI. Or, for example, the event may be triggered by both SRI and SAI; the specifics are not limited here.

[0296] The aforementioned events are triggered by both SRI and SAI, which can be understood as the perceived quality corresponding to the events including both SRI and SAI.

[0297] (6) The reported amount of events is related to perceived quality, that is, the reported amount of events includes at least one of SRI and SAI. It can also be understood that the perceived quality included in the measurement report includes at least one of SRI and SAI.

[0298] For example, the event reporting volume includes SRI, and the measurement report includes SRI. Another example is that the event reporting volume includes SAI, and the measurement report includes SAI. Yet another example is that the event reporting volume includes both SRI and SAI, and the measurement report includes both SRI and SAI; the specifics are not limited here.

[0299] It should be noted that (5) indicates which type of perceived quality is used to determine whether the event is satisfied, while (6) indicates which type of perceived quality is included in the reported measurement report when the event is satisfied.

[0300] The trigger quantity and the reported quantity can be the same or different. For example, the trigger quantity is SRI, and the reported quantity is SRI. Another example: the trigger quantity is SRI, and the reported quantity is SAI. Yet another example: the trigger quantity is SRI, and the reported quantity includes both SRI and SAI. Another example: the trigger quantity is SAI, and the reported quantity is SAI. Yet another example: the trigger quantity is SAI, and the reported quantity is SRI. Yet another example: the trigger quantity is SAI, and the reported quantity includes both SRI and SAI. And another example: the trigger quantity includes both SRI and SAI, and the reported quantity includes both SRI and SAI.

[0301] Furthermore, the parameter configurations for the aforementioned events can be related. For example, in the case of event S1, the measurement object is the serving cell, and the corresponding threshold is the first threshold. As another example, in the case of event S2, the measurement object is the serving cell, and the corresponding threshold is the second threshold. As yet another example, in the case of event S4, the measurement object is the neighboring cell, and the corresponding threshold is the fourth threshold. As yet another example, in the case of event S3, the measurement object includes both the serving cell and neighboring cells, and the corresponding threshold is the third threshold. As yet another example, in the case of event S5, the measurement object includes both the serving cell and neighboring cells, and the corresponding thresholds include both the fifth and sixth thresholds.

[0302] It is understood that the above items are merely examples, and the first piece of information can be used to indicate one or more of the above, and the parameter configuration of the event can include one or more of the above. In practical applications, the first piece of information can also indicate other parameters, and the parameter configuration of the event can also include other parameters; specific details are not limited here.

[0303] Similarly, the parameters indicated by the first information described above can be related. For example, if the event involves a serving cell, the resolution parameter indicated by the first information is the resolution parameter of the serving cell. As another example, if the event involves a neighboring cell, the resolution parameter indicated by the first information is the resolution parameter of the neighboring cell.

[0304] Step 602: The terminal device sends a measurement report to the network device.

[0305] The terminal device sends a measurement report to the network device. Correspondingly, the network device receives the measurement report sent by the terminal device. This measurement report includes a first sensing quality of the sensing area, which includes at least one of SRI and SAI.

[0306] In one possible implementation, the method provided in this embodiment includes step 601. After receiving first information, the terminal device performs measurements based on the first information to obtain a measurement report. Alternatively, it can be understood that the terminal device measures the sensing area to obtain a measurement report.

[0307] In another possible implementation, the method provided in this embodiment does not include step 601. The terminal device can determine the first information through pre-configuration or protocol specifications, and perform measurements based on the first information to obtain a measurement report.

[0308] Optionally, the terminal device first determines the size and dimension of the resolution unit based on the first information, and then determines the perceived quality based on the size and dimension of the resolution unit. The size of the resolution unit can be understood as the value of the resolution unit. The size of the resolution unit can be the area of ​​the resolution ellipse corresponding to the resolution unit or the volume of the resolution ellipsoid. The dimension of the resolution unit can be two-dimensional or three-dimensional. For example, when the dimension is two-dimensional, the size of the resolution unit is the area of ​​the ellipse. Or, for example, when the dimension is three-dimensional, the size of the resolution unit is the volume of the ellipsoid. For a detailed description of the size and dimension of the resolution unit, please refer to the relevant descriptions in the preceding terminology; they will not be elaborated upon here.

[0309] Optionally, the network device can also send a reference signal to the terminal device, which can measure the reference signal to obtain measurement results. The measurement results include at least one of the following: reference signal received power (RSRP), reference signal received quality (RSRQ), and signal-to-interference noise ratio (SINR). The type of the reference signal can be a synchronization signal block (SSB) or a channel status information reference signal (CSI-RS).

[0310] Correspondingly, the measurement report may also include the measurement results of the reference signal. Alternatively, it can be understood as: the measurement report includes the perceived quality of the sensing area and the measurement results of the reference signal.

[0311] The measurement report in this application embodiment may include one or more of the following: cell identifier, measurement results of reference signal, or measurement results of sensing area, etc., which are not specifically limited here.

[0312] For example, adding perceived quality (e.g., first perceived quality and / or second perceived quality) as a new field to the MeasResult IE is shown in the following example:

[0313]

[0314] As can be seen, adding "resultsSRI" to the MeasResult IE indicates the perceived quality of SRI, and adding "resultsSAI" indicates the perceived quality of SAI. Furthermore, the content of the MeasQuantityResults IE is as follows:

[0315]

[0316] As can be seen, by adding "sri" to MeasQuantityResults IE to indicate the measurement results of SRI, and adding "sai" to indicate the measurement results of SAI.

[0317] For ease of description, the following example will use a three-dimensional resolution unit, a base station as the network device, the first resolution parameter as the resolution parameter of the serving cell, and the second resolution parameter as the resolution parameter of the neighboring cell. In practical applications, it can also be two-dimensional sensing, with the first resolution parameter being the resolution parameter of the neighboring cell and the second resolution parameter being the resolution parameter of the serving cell, etc., but the specifics are not limited here.

[0318] The process of obtaining measurement reports by terminal devices is described below, depending on the different types of first information.

[0319] In the first scenario, the first information is used to indicate the sensing area and a first resolution parameter. This first resolution parameter is used to determine the first sensing quality, and the measurement report includes the first sensing quality.

[0320] In one possible implementation, the first resolution parameters include: range resolution parameters, azimuth resolution parameters, and pitch resolution parameters.

[0321] In this approach, after receiving the first resolution parameter, the terminal device can obtain the transformation matrix A based on the first resolution parameter, and determine the resolution cell size, i.e., the ellipsoidal volume, using the transformation matrix A. The process of obtaining the resolution cell size based on the range resolution parameter, azimuth resolution parameter, and elevation resolution parameter can be referred to the description in the aforementioned terminology section, and will not be repeated here.

[0322] Optionally, the serving base station of the serving cell can obtain the range resolution parameters in several ways. For example, the terminal device reports its own location to the serving base station. Another example is that the serving base station senses the location of the terminal device. Yet another example is that the serving base station estimates the location of the terminal device. After determining the location of the terminal device, the serving base station obtains the range resolution parameters by performing sensing measurements on the sensing area.

[0323] In another possible implementation, the first resolution parameters include: azimuth resolution parameters and pitch resolution parameters.

[0324] In this approach, frequent movement of the terminal device makes it difficult for the serving base station to determine the accurate location of the terminal device, or the serving base station cannot sense the location of the terminal device in a timely manner. In such cases, the serving base station sends out azimuth and elevation resolution parameters. The range resolution parameter is measured by the terminal device. Thus, the terminal device can determine the size of the resolution cell based on the azimuth, elevation, and range resolution parameters, and then determine the sensing quality based on the size of the resolution cell. The process of obtaining the resolution cell size based on the range, azimuth, and elevation resolution parameters can be referred to the description in the aforementioned terminology section, and will not be repeated here.

[0325] Optionally, the terminal device determines the first sensing quality based on the second information. This second information includes: the location of the terminal device, the location of the serving base station (i.e., the first network device), a first resolution parameter, and the sensing area. The first network device is the network device serving the cell.

[0326] Specifically, the terminal device first determines the range resolution parameters based on its location, the location of the serving base station, and the sensing area. Then, it determines the resolution cell size based on the range resolution parameters and the first resolution parameter. Similarly, the process of obtaining the resolution cell size based on the range resolution parameters, azimuth resolution parameters, and pitch resolution parameters can be referred to the descriptions in the aforementioned terminology, and will not be repeated here.

[0327] In the second scenario, the first information is used to indicate the sensing area and the second resolution parameter. This second resolution parameter is used to determine the second sensing quality, and the measurement report includes the second sensing quality.

[0328] In one possible implementation, the second resolution parameters include: range resolution parameters, azimuth resolution parameters, and pitch resolution parameters.

[0329] In this approach, after receiving the second resolution parameter, the terminal device can obtain the transformation matrix A based on the second resolution parameter, and determine the size of the resolution cell in the neighboring cell, i.e., the ellipsoidal volume, through the transformation matrix A. The process of obtaining the resolution cell size based on the range resolution parameter, azimuth resolution parameter, and pitch resolution parameter can be referred to the description in the aforementioned terminology section, and will not be repeated here.

[0330] Optionally, there are several ways for neighboring base stations in a neighboring cell to obtain range resolution parameters. For example, the terminal device reports its own location to the neighboring base station. Another example is that the terminal device reports its own location to the neighboring base station through the serving base station. Yet another example is that the neighboring base station senses the location of the terminal device. Yet another example is that the neighboring base station estimates the location of the terminal device. After determining the location of the terminal device, the neighboring base station obtains the range resolution parameters by performing sensing measurements on the sensing area.

[0331] In another possible implementation, the second resolution parameters include: azimuth resolution parameters and pitch resolution parameters.

[0332] In this approach, frequent movement of the terminal device makes it difficult for neighboring base stations to determine its precise location, or if neighboring base stations cannot promptly sense the terminal device's location, the neighboring base stations transmit azimuth and elevation resolution parameters. The range resolution parameter is measured by the terminal device, allowing it to determine the size of the resolution cell based on these parameters. The sensing quality is then determined based on the size of the resolution cell. The process of obtaining the resolution cell size from the range, azimuth, and elevation resolution parameters can be found in the aforementioned terminology descriptions and will not be repeated here.

[0333] Optionally, the terminal device determines the second sensing quality based on the second information. This second information includes: the location of the terminal device, the location of the neighboring base station (i.e., the second network device), the first resolution parameter, and the sensing area. The second network device is a network device in a neighboring cell.

[0334] Specifically, the terminal device first determines the range resolution parameters based on its location, the locations of neighboring base stations, and the sensing area. Then, it determines the resolution cell size based on the range resolution parameters and the first resolution parameter. Similarly, the process of obtaining the resolution cell size based on the range resolution parameters, azimuth resolution parameters, and pitch resolution parameters can be referred to the descriptions in the aforementioned terminology, and will not be repeated here.

[0335] Furthermore, the second piece of information also includes the signal bandwidth of neighboring cells. Accordingly, the terminal device determines the range resolution parameters based on the location of the terminal device, the location of neighboring base stations, the signal bandwidth of neighboring cells, and the sensing area.

[0336] In the third scenario, the first information is used to indicate the sensing area, the first resolution parameter, and the second resolution parameter. The measurement report includes both the first sensing quality and the second sensing quality.

[0337] The third scenario can be understood as a combination of the first and second scenarios mentioned above. Please refer to the descriptions of the first and second scenarios mentioned above for details, which will not be repeated here.

[0338] Furthermore, after acquiring the resolution unit size, the terminal device can determine the perceived quality based on the resolution unit size. For example, the terminal device determines the first resolution unit size based on a first resolution parameter, and then determines the first perceived quality based on the first resolution unit size. Alternatively, the terminal device determines the second resolution unit size based on a second resolution parameter, and then determines the second perceived quality based on the second resolution unit size. Another example is that the terminal device determines the first resolution unit size based on the first resolution parameter, determines the second resolution unit size based on the second resolution parameter, determines the first perceived quality based on the first resolution unit size, and then determines the second perceived quality based on the second resolution unit size. The process of determining the resolution size based on the resolution parameter can be referred to the description in the aforementioned terminology section, and will not be repeated here.

[0339] In this embodiment, the method by which the terminal device determines the perceived quality based on the resolution unit size is not limited; it is sufficient that the resolution unit size and the perceived quality are negatively correlated. That is, the larger the value of the resolution unit, the worse the perceived quality; the smaller the value of the resolution unit, the better the perceived quality.

[0340] For example, when the perceived quality is SRI, an example of the relationship between the resolution cell size and SRI can be shown in the following expression 1:

[0341] Expression 1: SRI = -P * log A (Resolution unit size);

[0342] Where P is a real number and A is the base, which can be e or 10, etc., and the specific number is not limited here.

[0343] For example, when the perceived quality is SAI, to ensure compatibility with signal quality or signal strength, the above expression can also be combined with RSRP, RSRQ, and signal-to-interference-plus-noise ratio (SINR). Taking SINR as an example, one example of the relationship between the resolution cell size and SAI can be shown in expression 2:

[0344] Expression 2: SAI = -Q * log C (resolution unit size / sqrt(SINR));

[0345] Where Q is a real number, sqrt represents the square root, and C is the base, which can be e or 10, etc., and is not limited here.

[0346] It is understood that expressions 1 and 2 above are merely examples. In practical applications, other expressions can be used to express a negative correlation between resolution cell size and perceived quality; specific examples are not limited here. For instance, the negative of the resolution cell size can be directly used as the perceived quality. Furthermore, there are other expressions showing a negative correlation between resolution cell size and perceived quality.

[0347] It should be noted that perceived quality is combined with at least one of RSRP, RSRQ, and SINR. The network device can also send a reference signal to the terminal device, which can measure the reference signal to obtain at least one of RSRP, RSRQ, and SINR.

[0348] Example 1, measuring 5 neighboring cells, with SRI = -10 * log 10 Taking the resolution cell size as an example, assuming the resolution cell sizes of the 5 neighboring cells are 1, 2, 4, 8, and 16 (e.g., square meters or cubic meters), the SRIs obtained by substituting them into the above formula example are 0, -3, -6, -9, and -12, respectively.

[0349] Example 2, with SAI = -10 * log 10 (Resolution unit size / sqrt(SINR)), SINR = 20 dB, then sqrt(SINR) = 10 dB, and the corresponding SAI = SRI + 10, that is, SAI is 10, 7, 4, 1, -2 respectively.

[0350] After determining the perceived quality, the terminal device sends a measurement report to the network device. This measurement report includes the perceived quality. Specifically, the perceived quality may refer to at least one of a first perceived quality and a second perceived quality. The first perceived quality is related to a first cell, and the second perceived quality is related to a second cell.

[0351] For example, taking the first cell as the serving cell and the second cell as a neighboring cell, the first perception quality is related to the serving cell. This can be understood as the first perception quality being related to the location of the serving base station, its angle measurement capability, the location of the terminal device, its signal bandwidth, and the perception area. Alternatively, it can be understood as the terminal device determining the first perception quality based on the location of the serving base station, its angle measurement capability, the location of the terminal device, its signal bandwidth, and the perception area.

[0352] Similarly, the second sensing quality is related to neighboring cells, which can be understood as being related to the location of neighboring base stations, their angle measurement capabilities, the location of the terminal device, signal bandwidth, and the sensing area. Alternatively, it can be understood as the terminal device determining the second sensing quality based on the location of neighboring base stations, their angle measurement capabilities, the location of the terminal device, signal bandwidth, and the sensing area.

[0353] For example, after determining the first perceived quality, the terminal device sends a measurement report to the network device that includes the first perceived quality. As another example, after determining the second perceived quality, the terminal device sends a measurement report to the network device that includes the second perceived quality. Yet another example, after determining both the first and second perceived qualities, the terminal device sends a measurement report to the network device that includes both the first and second perceived qualities.

[0354] It is understood that the method provided in this embodiment may include steps 601 and 602, or the method provided in this embodiment may include step 602, etc., and the specifics are not limited here.

[0355] In this embodiment, the terminal device and the network device exchange first information and a measurement report to transmit the first perception quality of the sensing area. This first perception quality includes at least one of a perception resolution index and a perception accuracy index. On one hand, compared to the signal quality and signal power included in the measurement report in the prior art, the measurement report in this application includes cell-related perception quality, thus defining the measurement report from a perception perspective. This allows the measurement report to provide a reference for the network device to perform redirection, cell reselection, or cell handover. On the other hand, having the terminal device determine the distance-oriented resolution parameter in the resolution parameters can reduce deviations caused by frequent movement of the terminal device, improving the timeliness and accuracy of the perception quality.

[0356] Furthermore, after receiving the measurement report sent by the terminal device, the network device can make a handover decision based on the measurement report, generate and send a handover request, and thus execute the handover process. Alternatively, the measurement report can be understood as being used for handover decision-making.

[0357] The handover decision can employ different handover strategies. These strategies can be SRI-triggered, SAI-triggered, or a combination of both, etc., without specific limitations here. For example, a larger SRI generally results in better performance. Similarly, a larger SAI generally results in better performance.

[0358] Optionally, after receiving the measurement report, the network device can determine the neighboring cells to be handed over based on the measurement report and the handover policy, thereby executing the handover process. The process of determining the neighboring cells to be handed over in this embodiment can also be referred to as the process of filtering neighboring cells.

[0359] For example, a measurement report includes the SRI of the measured object and the identifier of the first neighboring cell. After receiving the measurement report, the network device can determine the neighboring cell to be handed over based on the SRI. For example, the first neighboring cell with the highest SRI can be selected as the second neighboring cell. Alternatively, multiple first neighboring cells can be sorted from highest to lowest SRI, and one neighboring cell can be randomly selected from the top k as the second neighboring cell.

[0360] For example, a measurement report includes the SAI of the measured object and the identifier of the first neighboring cell. After receiving the measurement report, the network device can determine the neighboring cell to be switched based on the SAI. For example, the first neighboring cell with the highest SAI can be selected as the second neighboring cell. Alternatively, multiple first neighboring cells can be sorted from highest to lowest SAI, and one neighboring cell can be randomly selected from the top k as the second neighboring cell.

[0361] For example, a measurement report includes the SRI and SAI of the measured object, as well as the identifier of the first neighboring cell. After receiving the measurement report, the network device can determine the neighboring cell to be handed over based on the SRI and SAI.

[0362] For example, continuing with the examples in Examples 1 and 2, the measurement report includes multiple first neighboring cells and the perceived quality of each first neighboring cell, as shown in Table 3:

[0363] Table 3

[0364] First Neighborhood Sign SRI SAI 0 -9 4 1 -3 10 2 -6 1 3 -12 7 4 0 -2

[0365] In one possible implementation, the network device determines the neighboring cells to be handed over based on SRI and SAI. This includes: the network device first filters multiple first neighboring cells based on SRI, and then determines the second neighboring cell among the filtered first neighboring cells as the neighboring cell to be handed over based on SAI. This method can also be called the SRI filtering and SAI sorting method.

[0366] For example, continuing with the example in Table 3 above, suppose we first obtain 3 neighboring cells based on SRI filtering (e.g., neighboring cell 4, neighboring cell 1, and neighboring cell 2). Then, we sort the 3 neighboring cells based on SAI to obtain the following order: neighboring cell 1, neighboring cell 2, and neighboring cell 4. We can then determine that neighboring cell 1, which has the highest SAI, is the second neighboring cell.

[0367] In another possible implementation, the network device determines the neighboring cells to be handed over based on SRI and SAI. This involves the network device first filtering multiple first neighboring cells based on SAI, and then determining the second neighboring cell among the filtered first neighboring cells as the neighboring cell to be handed over based on SRI. This method can also be called SAI filtering and SRI sorting.

[0368] For example, continuing with the example in Table 3 above, suppose we first filter based on SAI to obtain 3 neighboring cells (e.g., neighboring cell 1, neighboring cell 3, and neighboring cell 0). Then, we sort the 3 neighboring cells based on SRI to obtain the following order: neighboring cell 1, neighboring cell 0, and neighboring cell 3. We can then determine that neighboring cell 1, which has the highest SAI, is the second neighboring cell.

[0369] Based on the above scheme, on the one hand, when making handover decisions, network devices can consider not only a single type of perception quality but also multiple types of perception quality. This ensures not only better perception resolution of the neighboring cells to be handed over but also better perception accuracy, thereby improving user experience. On the other hand, by referencing signal quality / strength in the perception quality calculation process, neighboring base stations determined based on perception quality have better perception and communication quality, thus improving user experience.

[0370] The method provided in the embodiments of this application has been described above from the perspective of the air interface. For ease of understanding, the following section describes the method from the perspective of devices that may be involved in the communication system. Figure 6 The illustrated embodiments will be described in further detail.

[0371] Another communication method provided in the embodiments of this application is as follows: Figure 7 As shown. The method may include steps 701 to 706. Steps 701 to 706 may be executed by a communication device, or by some components of the communication device (e.g., processor, circuit, chip, or chip system), or by a logic module or software capable of implementing all or part of the functions of the communication device. The following description uses execution by a communication device as an example. The processing performed by a single execution entity in steps 701 to 706 can also be divided into multiple execution entities, which may be logically and / or physically separated. For example, when the communication device is an access network device, the processing performed by the communication device may be divided into execution by at least one network element such as CU, DU, or RU. This method can be applied to the aforementioned... Figures 4 to 6 In any of the embodiments shown, no specific limitation is made here.

[0372] Step 701: The first network device sends the first information to the terminal device.

[0373] In this embodiment, the first network device can be a network device in the first cell where the terminal device is located, and the second network device can be a network device in a neighboring cell of the first cell where the terminal device is located. Taking a base station as an example, the first network device can be the serving base station of the terminal device, and the second network device can be a neighboring base station. In handover scenarios, the serving base station can also be called the source base station, and the neighboring base station can also be called the target base station.

[0374] The first network device sends first information to the terminal device, and correspondingly, the terminal device receives the first information sent by the network device. The description of this first information can be found in the foregoing. Figure 6 The description of step 601 in the illustrated embodiment will not be repeated here.

[0375] Step 702: The terminal device determines the size of the resolution unit based on the resolution parameters.

[0376] After receiving the first information, the terminal device determines the size of the resolution unit based on the resolution parameters.

[0377] The method for determining the size of the resolution unit based on the resolution parameters can be found in the descriptions in the aforementioned terminology section, and will not be repeated here.

[0378] Optionally, the terminal device can also determine the dimension of the resolution unit based on the resolution parameters. This dimension can also be determined based on configuration or pre-configuration, and there is no specific limitation here.

[0379] One possibility is that the resolution parameters indicated by the first information include range resolution parameters, azimuth resolution parameters, and pitch resolution parameters. In this case, the terminal device can first determine the transformation matrix A based on the resolution parameters, and then determine the size of the resolution unit using the transformation matrix A.

[0380] Another possibility is that the resolution parameters indicated by the first information include azimuth and elevation resolution parameters, but not range resolution parameters. In this case, the terminal device first determines the range resolution parameters based on the location of the terminal device, the location of the base station, and the sensing area. Then, it determines the transformation matrix A using the range, azimuth, and elevation resolution parameters, and finally determines the size of the resolution cell using the transformation matrix A.

[0381] Understandably, if the resolution cell size of the serving cell or serving base station is measured, the resolution parameter obtained by the terminal device will be the resolution parameter of the serving cell or serving base station. Similarly, if the resolution cell size of a neighboring cell or neighboring base station is measured, the resolution parameter obtained by the terminal device will be the resolution parameter of the neighboring cell or neighboring base station.

[0382] Step 703: The terminal device calculates the perceived quality based on the resolution unit size.

[0383] Once the terminal device determines the resolution unit size, it can calculate the perceived quality based on the resolution unit size.

[0384] For example, if perceived quality includes SRI, the terminal device can determine SRI based on the resolution cell size and the aforementioned expression 1. As another example, if perceived quality includes SAI, the terminal device can determine SAI based on the resolution cell size and the aforementioned expression 2. Yet another example is using other methods to calculate perceived quality.

[0385] It is understandable that expressions 1 and 2 mentioned above are only a few examples of the relationship between resolution cell size and perceived quality. In practical applications, there may be other relationships between resolution cell size and perceived quality, which are not limited here. For example, the negative of the resolution cell size can be directly used as the perceived quality. Furthermore, there are other expressions showing a negative correlation between resolution cell size and perceived quality.

[0386] Step 704: The terminal device sends a measurement report to the first network device.

[0387] After acquiring the perceived quality, the terminal device sends a measurement report to the first network device. Correspondingly, the first network device receives the measurement report sent by the terminal device.

[0388] Optionally, the terminal device can first determine the event type based on the perceived quality and triggering parameters, and then generate a measurement report. This measurement report may include the identifier of the neighboring cell and the perceived quality corresponding to the identifier.

[0389] Step 705: The first network device filters neighboring cells based on perceived quality.

[0390] After receiving the measurement report, the first network device can filter neighboring cells based on the perceived quality in the measurement report.

[0391] The process of selecting neighboring cells based on perceived quality can be referred to the aforementioned. Figure 6 The illustrated embodiments and Figure 7 The descriptions of the middle sections in the illustrated embodiment will not be repeated here.

[0392] Step 706: The terminal device, the first network device, the second network device, and the core network perform a handover.

[0393] After the first network device filters neighboring cells, the terminal device, the first network device, the second network device, and the core network perform the handover.

[0394] Optionally, the handover process includes: a first network device sending a handover request to a second network device, and the second network device responding with a request confirmation. The first network device sends an RRC reconfiguration message containing a handover command message to the terminal device, which carries information required for accessing the target cell (e.g., the target cell identifier, a new cell radio network temporary identifier). The first network device sends an SN STATUS TRANSFER message to the second network device. The terminal device synchronizes with the target cell and completes the RRC handover process by sending an RRC Reconfiguration Complete message to the second network device. The second network device sends a path switching request message to the core network to trigger the core network to switch the downlink data path to the second network device.

[0395] In this embodiment, the terminal device and the network device exchange first information and a measurement report to transmit the first perception quality of the perception area. This first perception quality includes at least one of a perception resolution index or a perception accuracy index. On one hand, compared to the signal quality and signal power included in the measurement report in the prior art, the measurement report in this application includes cell-related perception quality, limiting the measurement report from a perception perspective. This allows the measurement report to provide a reference for the network device to perform redirection, cell reselection, or cell handover. On the other hand, having the terminal device determine the distance-oriented resolution parameter in the resolution parameters can reduce deviations caused by frequent terminal device movement, improving the timeliness and accuracy of the perception quality. Furthermore, when making handover decisions, the network device can consider not only a single type of perception quality but also multiple types of perception quality. This ensures not only superior perception resolution of the neighboring cell to be handed over but also superior perception accuracy, thereby improving the user experience. Additionally, the calculation of perception quality considers signal quality / strength, ensuring that neighboring base stations determined based on the perception quality have superior perception and communication quality, further enhancing the user experience.
