Information reporting method and communication device

[0001] This application claims priority to the Chinese patent application with application number 202310948379.8 filed with the State Intellectual Property Office of China on July 28, 2023, and priority to the Chinese patent application with the invention name “A method and communication device for reporting information”, all contents of which are incorporated by reference into this application. Technical Field

[0002] The present application relates to the field of communication technology, and in particular to an information reporting method and a communication device. Background Art

[0003] Currently, high-precision positioning technology is one of the key technologies of the fifth-generation mobile communication technology new radio (5G NR) mobile communication network. Cellular positioning can accurately identify the location of user equipment (UE), thereby providing various location-based services such as navigation, transportation, and industrial robotics. However, the positioning capabilities for the sixth-generation mobile communication technology (6G) are expected to achieve wireless sensing capabilities through positioning reference signals, and realize real-time environmental perception through wireless sensing capabilities, enabling sensing capabilities while further improving positioning accuracy.

[0004] Specifically, the base station usually needs to use an antenna array (including multiple antennas) to measure the positioning reference signal from the UE and report the measurement results (such as channel state information (CSI) or channel impulse response (CIR) or power delay profile (PDP)) to the positioning center, thereby building perception capabilities under the positioning network, further perceiving the positions of various reflectors in the environment, and utilizing the measurement information of the reflection path in space to improve positioning accuracy in harsh channel environments. However, reporting channel measurement results often leads to higher signaling overhead and higher network load. Therefore, how to save the overhead of reporting channel measurement results is a problem to be solved.

[0005] Summary of the Invention

[0006] The embodiments of the present application provide an information reporting method and a communication device, which can save the overhead of reporting channel measurement results.

[0007] In a first aspect, the present application provides an information reporting method, which includes: receiving a measurement request message from a first network element, the measurement request message being used to request measurement channel information; and reporting a first measurement result and first information to the first network element according to the measurement request message, the first information indicating first angle information or first beam information corresponding to the first measurement result.

[0008] In the method described in the first aspect, after receiving the measurement request message from the first network element, only the measurement results in one or more directions or only the measurement results within a certain range can be reported, thereby avoiding the reporting of omnidirectional multi-antenna measurement results, which is beneficial to saving the overhead of reporting channel measurement results.

[0009] In one possible implementation, the first information includes one or more pieces of first beam information corresponding to the first measurement result, and the first measurement result is calculated based on a second measurement result corresponding to the one or more pieces of first beam information. Based on this approach, since the second measurement result corresponding to the one or more pieces of first beam information can be obtained by combining measurement results obtained from each antenna in the antenna array using beamforming, reporting of omnidirectional multi-antenna measurement results is avoided, which helps reduce the overhead of reporting channel measurement results.

[0010] In a possible implementation, the first beam information includes one or more of the following information: a first angle value of the first beam, a first angle range of the first beam, an index value of the first beam, and an index value of a reference signal associated with the first beam.

[0012] In one possible implementation, the measurement request message includes first indication information; the first indication information indicates second angle information corresponding to the channel information requested for measurement, or the first indication information indicates one or more second beams corresponding to the channel information requested for measurement. Based on this approach, in scenarios where the first network element is only interested in channel measurement results within a certain characteristic direction or angle range, the first network element can instruct the access network device to report only the measurement results within that partial range, thereby avoiding the reporting of omnidirectional multi-antenna measurement results and reducing the overhead of channel measurement result reporting.

[0013] In one possible implementation, the first indication information includes information of one or more second beams; the information of the second beam includes one or more of the following information: a third angle value of the second beam, a third angle range of the second beam, an index value of the second beam, and an index value of a reference signal associated with the second beam.

[0014] In a possible implementation, the second angle information includes one or more fourth angle values, or the second angle information includes one or more fourth angle ranges. Based on this approach, the complexity of information indication can be reduced.

[0015] In a possible implementation, the first beam or the second beam is a beam at a diameter level. Based on this approach, the energy of a certain diameter can be maximized.

[0016] In a possible implementation, the first information includes path information, where the path information is information about the path associated with the beam information.

[0017] In a possible implementation, the path information includes one or more of the following information: a path identifier, a path name, and reflector information associated with the path.

[0018] In one possible implementation, the first measurement result includes one or more of the following information: channel state information CSI, channel impulse response CIR, power delay profile PDP, and channel frequency response CFR. Based on this approach, the diversity of the first measurement result can be improved.

[0019] In second aspect, the present application provides an information reporting method, which includes: sending a measurement request message to an access network device or a terminal device, the measurement request message being used to request measurement channel information; receiving a first measurement result and first information from the access network device or the terminal device, the first information indicating a first angle information or first beam information corresponding to the first measurement result.

[0023] In a possible implementation, the first angle information includes one or more second angle values, or the first angle information includes one or more second angle ranges.

[0061] 1. Terminal Equipment

[0064] The RAN may include one or more RAN devices (or access network devices). The interface between the access network device and the terminal device may be a Uu interface (or air interface). Of course, in communications evolved after 5G, the names of these interfaces may remain unchanged or may be replaced by other names, and this application does not limit this.

It may also include centralized units (C-RAN) in cloud radio access network (C-RAN) systems. The RAN in this application may be a 5G RAN or a 6G RAN, and this application does not limit this.

[0066] 3. CN

[0067] The CN may include one or more CN devices (which may be understood as network element devices or network functions (NFs)). In the following text, the CN devices are collectively referred to as network elements (eg, the first network element in the following text).

[0068] Please refer to Figure 2, which is a schematic diagram of a core network architecture provided by the present application. The CN in Figure 2 is a schematic diagram of the CN in the 5G network architecture. The CN shown in Figure 2 includes multiple CN devices: network slice selection function (NSSF), network exposure function (NEF), network function repository function (NRF), policy control function (PCF), unified data management (UDM), application function (AF), network control function (NCF), network slice specific authentication and authorization function (NSSAAF), authentication server function (AUSF), access and mobility management function (AMF), location management function (LMF), session management function (SMF), user plane function (UPF), service communication proxy (SCP), network slice admission control function (NSACF), etc. Among them:

[0069] AMF is a control plane function provided by the operator network, responsible for access control and mobility management of terminal devices accessing the operator network, such as mobile state management, allocation of user temporary identity, authentication and authorization of users, etc. In the embodiment of the present application, AMF can receive a location information request for a certain UE initiated by other network elements in the network, and then send the received request to the positioning server LMF. LMF is responsible for processing the received positioning information request and initiating the relevant positioning process.

[0070] LMF is mainly used to provide location positioning for services such as emergency rescue, navigation, and location-based management. LMF can determine the UE's location information based on a request from a core network entity (such as an access and mobility management function (AMF)) and provide the UE's location information to the AMF, thereby providing location services (LCS). In an embodiment of the present application, the first network element may be an LMF, and the LMF may be a location server / positioning center, which may be integrated into an access network device and may also be referred to as a Local LMF. It should be noted that "positioning" can be translated into any of location, positioning, position, localization, etc., that is, the above four words can be directly interchangeable, and are not limited to the singular or plural. In addition, the two words "positioning" and "location" can also be directly interchangeable. For example, "positioning information request" and "location information request" can have the same or similar meanings; "positioning center" and "location center" can have the same or similar meanings; "positioning server" and "location server" can have the same or similar meanings; and so on. The present invention does not limit this.

[0071] SMF is a control plane function provided by the operator network, responsible for managing the protocol data unit (PDU) sessions of terminal devices. A PDU session is a channel for transmitting PDUs. Terminal devices need to transmit PDUs to and from the DN through PDU sessions. The SMF is responsible for establishing, maintaining, and deleting PDU sessions. SMF includes session management (such as session establishment, modification, and release, including tunnel maintenance between the UPF and RAN), UPF selection and control, service and session continuity (SSC) mode selection, roaming, and other session-related functions.

[0072] The PCF is a control plane function provided by the operator, including user subscription data management, policy control, charging policy control, and Quality of Service (QoS) control. It is mainly used to provide PDU session policies to the SMF. Among them, the policies may include charging-related policies, QoS-related policies, and authorization-related policies.

[0073] The UPF is a gateway provided by the operator, serving as the gateway for communication between the operator's network and the DN. The UPF includes user-plane-related functions such as packet routing and transmission, packet inspection, quality of service (QoS) processing, uplink packet inspection, and downlink packet storage.

[0074] The UDM is primarily used to manage user subscription and authentication data, as well as perform authentication credit processing, user identity processing, access authorization, registration / mobility management, subscription management, and short message management. In some embodiments, the UDM may also include a unified data repository (UDR). Alternatively, in other embodiments, the 3GPP SBA of the 5G system may also include a UDR. The UDR is used to provide storage and retrieval for PCF policies, storage and retrieval of open structured data, and storage of user information requested by application functions.

[0075] It should be noted that the above-mentioned CN devices may also be referred to as network elements or functional network elements. In a 5G communication system, each functional network element may be the name of each functional network element shown in Figure 2. In a communication system evolved after 5G (such as a 6G communication system), each functional network element may still be the name of each functional network element shown in Figure 2, or may have other names. For example, in a 5G communication system, the user plane function may be a UPF. In a communication system evolved after 5G (such as a 6G communication system), the user plane function may still be a UPF, or may have other names, which is not limited in this application.

[0076] It should also be noted that in the 5G communication system, the functions implemented by each functional network element can be independent as shown in Figure 2. In the communication system evolved after 5G (such as the 6G communication system), each functional network element can still be in an independent state as shown in Figure 2, or the functions of multiple functional network elements in Figure 2 can be implemented by an integrated functional network element. For example, in the 5G communication system, the user plane related functions are implemented by the UPF, and the access and mobility management related functions are implemented by the AMF. In the communication system evolved after 5G (such as the 6G communication system), the user plane related functions can still be implemented by the UPF, and the access and mobility management related functions can still be implemented by the AMF, or the user plane related functions and the access and mobility management related functions can be implemented by an integrated functional network element at the same time, which is not limited in this application.

[0077] In Figure 2, Npcf, Nudm, Naf, Namf, Nsmf, Nlmf, N1, N2, N3, N4, and N6 are interface serial numbers. The meanings of these interface serial numbers are defined in relevant standard protocols and are not limited here.

[0078] 4. DN

[0079] DN, also known as packet data network (PDN), is a network located outside the operator network. The operator network can access multiple DNs. Application servers corresponding to various services can be deployed in the DN to provide a variety of possible services for terminal devices.

[0080] To facilitate understanding of the solutions provided by the embodiments of the present application, the following describes the relevant concepts involved in the embodiments of the present application:

[0081] 1. Wireless sensing technology

[0082] Wireless sensing uses wireless signals to detect environmental information. This information includes the distribution, size, quantity, temperature, and movement of objects, even breathing and heart rates. This environmental perception can then be combined with other technologies, such as artificial intelligence, for subsequent processing, enabling reconstruction of the physical environment, analysis of the environment, identification and analysis of people and objects within it, and triggering subsequent actions. Wireless sensing technology makes it possible to reconstruct crucial information about the environment covered by the wireless signal on a computer without the need to capture on-site images or video.

[0083] The principle of wireless sensing is to transmit radio signals to the environment to be sensed, while the receiving end collects the wireless signals that have been reflected, scattered, and transmitted through multiple paths. Because the collected wireless signals have been subjected to the environment, they carry environmental information. After receiving the signals, complex signal processing is performed to discover the characteristics of the environment. The perceived environment can then be reconstructed on a computer, including identifying people and objects in the environment, detecting temperature, human movement, and even breathing and heart rate. This technology is used in fields such as human health monitoring and security.

[0084] 2. Line of sight (LOS) and non-line of sight (NLOS) paths

[0085] In cellular mobile terminal positioning systems, the LOS path refers to the straight-line path between the terminal device and the access network equipment. The NLOS path refers to the path where the radio wave propagates through NLOS propagation methods, such as reflection, refraction, and diffraction, due to obstacles in the wireless transmission environment. As shown in Figure 3, the positioning reference signal can be transmitted between the terminal device and the access network equipment along the LOS path, or it can be reflected or diffracted through reflectors or scatterers along the NLOS path.

[0086] For traditional positioning methods such as time difference of arrival (TDOA) and angle of arrival (AOA), when the position of the scatterer / reflector is unknown, the terminal device cannot utilize the positioning reference signal transmitted via the NLOS path and the corresponding measurement. However, when the network has perception capabilities, that is, it can perceive the position of each scatterer in the environment, then the positioning reference signal transmitted via the NLOS path can be utilized in the process of positioning the UE. In other words, building perception capabilities under the positioning network can utilize the measurement information of the reflection path in space, enabling NLOS path positioning.

[0087] 3. Channel measurement results

[0088] For cellular positioning systems, in wireless sensing technology, it is usually necessary for terminal devices or access network devices to report the measurement results obtained by measuring the channel to the positioning center (such as LMF) to achieve wireless sensing. In addition, in addition to achieving wireless sensing, the reported measurement results can also achieve wireless fingerprint positioning, that is, pre-building a wireless fingerprint library, and then matching and comparing the reported measurement results with the wireless fingerprint library to obtain the UE's location result. In an embodiment of the present application, the measurement results can be channel state information (CSI), channel impulse response (CIR), power delay profile (PDP), channel frequency domain coefficient (CFR), channel coefficient corresponding to the channel frequency domain subcarrier or channel coefficient corresponding to each resource element (RE), etc.

[0089] Specifically, a base station typically uses an antenna array (including multiple antennas) to measure the positioning reference signal (PRS) from the UE and reports the measurement results obtained by each antenna to the positioning center. This builds perception capabilities within the positioning network, further detecting the locations of various reflectors in the environment and utilizing the measurement information of the reflection path in space to improve positioning accuracy in harsh channel environments. However, reporting the measurement results obtained by each antenna often results in high signaling overhead and high network load. For example, for a frequency range 1 (FR1) orthogonal frequency division multiplexing (OFDM) system with a 100MHz bandwidth and 4096 subcarriers, each subcarrier has two values: in-phase and quadrature, each quantized using 16 bits. Assuming a base station or terminal device is equipped with four antennas, the reporting overhead is: 4096*2*16*4*4 = 2097152 bits, which is bound to impose an extremely high load on the network.

[0090] Therefore, in order to reduce the overhead of reporting channel measurement results, the present application provides an information reporting method and a communication device. The information reporting method and the communication device provided in the embodiments of the present application are further described in detail below.

[0091] Figure 4 is a flow chart of an information reporting method provided in an embodiment of the present application. As shown in Figure 4, the information reporting method includes the following steps S401 and S402. The execution subject of the method shown in Figure 4 can be the access network device and the first network element mentioned above. Alternatively, the execution subject of the method shown in Figure 4 can be a chip in the access network device and a chip in the first network element, which is not limited in the embodiment of the present application. Figure 4 illustrates the execution subject of the method using the access network device and the first network element as an example. In addition, the first network element can be an independent device or can be integrated in the access network device, which is not limited here. The embodiment of the present application illustrates the first network element as an independent device.

[0092] S401: A first network element sends a measurement request message to an access network device. Correspondingly, the access network device receives the measurement request message from the first network element.

[0093] In an embodiment of the present application, the measurement request message is used to request measurement of channel information. The channel information requested for measurement may refer to information related to the channel, such as CSI, CIR, PDP, CFR, channel angle information, channel delay information, channel frequency domain coefficients, channel coefficients corresponding to frequency domain subcarriers, or channel coefficients corresponding to each RE, etc., without limitation herein. The first network element may be an LMF, a positioning server, or a positioning center, etc., without limitation herein.

[0094] It should be noted that "positioning" can be translated as any of location, positioning, position, localization, etc. Location, positioning, position, and localization can replace each other in different scenarios in this application. Positioning center, positioning server, location center, location management function, etc. can all express the same meaning, indicating nodes / functions / services / devices with location or positioning-related functions. In addition, the words "measurement message request" and "request measurement message", "providing measurement information" and "measurement information provision" do not affect the meaning when the order is changed. They can be directly replaced and also express the same meaning. This application does not limit the order of phrases.

[0095] S402: The access network device reports the first measurement result and the first information to the first network element according to the measurement request message. Correspondingly, the first network element receives the first measurement result and the first information from the access network device.

[0096] In an embodiment of the present application, the first information indicates the first angle information or first beam information corresponding to the first measurement result. Regarding the specific process of the access network device reporting the first measurement result, first, the first network element needs to request the terminal device's positioning capability information from the terminal device. Accordingly, the terminal device reports its positioning capability information to the first network element. Then, the first network element requests the reference signal configuration information from the access network device based on the terminal device's positioning capability information. Accordingly, the access network device determines the available reference signal resources and configuration. After the determination is made, the access network device configures the reference signal resources to the terminal device through radio resource control (RRC) signaling. Simultaneously, the access network device also notifies the first network element of the reference signal configuration information. The reference signal may be a sounding reference signal (SRS). Furthermore, the terminal device can send a reference signal to the access network device. After receiving the measurement request message sent by the first network element, the access network device can measure the reference signal from the terminal device, obtain a first measurement result, and report the first measurement result to the first network element. The first network element can then use the first measurement result to locate the terminal device.

[0097] The access network device is equipped with an antenna array, which may include multiple antennas. When the access network device measures the reference signal from the terminal device, a measurement result can be obtained on each antenna. To avoid reporting omnidirectional multi-antenna measurement results and reduce the overhead of reporting channel measurement results, the access network device may only report measurement results in one or more directions or within a certain angle range. In other words, the first measurement result may be a measurement result in a certain direction or within a certain angle range. Therefore, in addition to reporting the first measurement result, the access network device also needs to indicate the first angle information or first beam information corresponding to the first measurement result.

[0098] It should be noted that the first angle information corresponding to the first measurement result can also be understood as the first angle information associated with the first measurement result; and the first beam information corresponding to the first measurement result can also be understood as the first beam information associated with the first measurement result. In other words, the term "corresponding" is interchangeable with "associated."

[0099] In one possible implementation, the first measurement result includes one or more of the following information: CSI, CIR, PDP, CFR. Of course, the first measurement result may also be a channel coefficient corresponding to a channel frequency domain subcarrier or a channel coefficient corresponding to each RE, etc., which is not limited here.

[0100] Regarding the case where the first information may indicate the first angle information or the first beam information corresponding to the first measurement result, the first information is described in detail below.

[0101] (1) The first information indicates first beam information corresponding to the first measurement result.

[0102] In a possible implementation, the first information includes one or more first beam information corresponding to the first measurement result, and the first measurement result is calculated based on the second measurement results corresponding to the one or more first beam information.

[0103] The first measurement result is calculated based on the second measurement results corresponding to one or more pieces of first beam information. This can also be understood as: the first measurement result is obtained based on the second measurement results corresponding to one or more pieces of first beam information. In other words, the first measurement result can be determined based on the second measurement results corresponding to one or more pieces of first beam information.

[0104] Optionally, the second measurement result includes one or more of the following information: CSI, CIR, PDP, CFR. Of course, the second measurement result may also be a channel coefficient corresponding to a frequency domain subcarrier or a channel coefficient corresponding to each RE, etc., which is not limited here.

[0105] In a specific implementation, after the antenna array equipped with the access network device receives the reference signal from the terminal device, each antenna in the antenna array will measure and obtain a measurement result. As shown in Figure 5, taking the measurement result as an example, when the antenna array equipped with the access network device contains n antennas, the CIR sequence corresponding to the n antennas can be obtained, that is, the CIR sequence corresponding to the first antenna is h1(t), the CIR sequence corresponding to the second antenna is h2(t), and the CIR sequence corresponding to the nth antenna is h n (t). Where t represents time.

[0106] If the access network device reports the measurement results measured by each antenna, it will cause high signaling overhead and lead to higher network load. Therefore, the access network device can use receiver beamforming to merge the measurement results obtained by each antenna in the antenna array to obtain one or more second measurement results corresponding to the first beam information. By calculating the second measurement results corresponding to the one or more first beam information, the first measurement result can be obtained (it can also be understood that the first measurement result is obtained based on the second measurement results corresponding to the one or more first beam information). The access network device only needs to report the first measurement result to the first network element, which greatly saves the overhead of reporting the channel measurement results.

[0107] The basic principle of beamforming can be expressed as follows:

[0108] h rx_m (n)=a(θ)[h1(n),h2(n),...,h N (n)] (1)

[0109] In formula (1), h rx_m (n) represents the beam vector with index value m, for example h rx_1 (n) represents the beam vector with index value 1, h rx_2 (n) represents the beam vector with index value 2. h N (n) represents the measurement result obtained by measuring the Nth antenna element. For example, h1(n) represents the measurement result obtained by measuring the first antenna element, and h2(n) represents the measurement result obtained by measuring the second antenna element. a(θ) represents the steering vector, which can be expressed as shown in formula (2).

[0110] In formula (2), φ k Controls the angular direction of the beam, or Where d represents the distance between antenna elements and λ is a constant. k There are also other forms, such as k represents the kth beam, M represents the number of antenna elements, which is not limited in the present embodiment. The sign can be positive or negative, i.e. or The embodiments of the present application are not limiting either.

[0111] As shown in FIG6, taking the first measurement result as a CIR sequence as an example, the access network device can combine the measurement results obtained by measuring each antenna in the antenna array in a beamforming manner to obtain a second measurement result corresponding to the first beam information 1 (as shown in FIG7A, i.e., h rx_1 (n)) and the second measurement result corresponding to the first beam information 2 (as shown in FIG7B , i.e., h rx_2 (n)). Among them, the first beam information 1 is the first beam information corresponding to beam 1, and the first beam information 2 is the first beam information corresponding to beam 2.

[0112] In a possible implementation, for the case where the first measurement result is calculated based on the second measurement results corresponding to one or more first beam information, the calculation method of the first measurement result is described in detail below.

[0113] Method 1: The first measurement result includes one or more second measurement results corresponding to the first beam information.

[0114] In a specific implementation, the access network device can directly report the second measurement results corresponding to one or more first beam information. In other words, the first measurement result can be directly equal to the second measurement results corresponding to the one or more first beam information, without any further processing. Because the second measurement results corresponding to the one or more first beam information are obtained by combining the measurement results obtained from each antenna in the antenna array using beamforming, the reporting of omnidirectional multi-antenna measurement results is avoided, and to a certain extent, the overhead of reporting channel measurement results is reduced.

[0115] For example, taking the second measurement result as the CIR sequence, the CIR sequence corresponding to the first beam information 1 is h rx_1 (n), the CIR sequence corresponding to the first beam information 2 is h rx_2 (n). The first measurement result can be directly h rx_1 (n) and h rx_2 (n).

[0116] Method 2: The first measurement result is obtained by performing a weighted sum operation on the second measurement results corresponding to one or more first beam information.

[0117] In a specific implementation, the access network device can weight and process the second measurement results corresponding to one or more beam information, and report the obtained measurement results (i.e., the first measurement results) to the first network element. Based on this approach, the second measurement results corresponding to different first beam information can be weighted and combined before being reported, thereby further reducing the channel measurement result reporting overhead. The weight value of the second measurement result corresponding to each first beam information can be any real number, any complex number, or any vector, and is not limited here.

[0118] As shown in FIG7C , taking the second measurement result as an example of a CIR sequence, the CIR sequence corresponding to the first beam information 1 is h rx_1 (n), the CIR sequence corresponding to the first beam information 2 is h rx_2 (n). The weight value 1 of the CIR sequence corresponding to the first beam information 1 is a, and the weight value 2 of the CIR sequence corresponding to the first beam information 2 is b. rx_1 (n) and h rx_2 (n) Perform weighted sum calculation to obtain a first measurement result. Wherein, a and b can be the same or different, and a and b can be real numbers, complex numbers or vectors. When a is equal to b, it means that the weighted values ​​are combined h rx_1 (n) and h rx_2 (n); when a and b are vectors, it means h rx_1 Different points in (n) (i.e. different n values) and hrx_2 The different points in (n) are weighted and calculated.

[0119] Optionally, the first information also includes a weight value of the second measurement result corresponding to each piece of first beam information. In other words, in addition to merging the second measurement results corresponding to different pieces of first beam information before reporting, the access network device also indicates a merging method, so that after receiving the first measurement result, the first network element can determine the second measurement result corresponding to each piece of first beam information based on the merging method.

[0120] Method three: the first measurement result is obtained by performing time domain splicing on the second measurement results corresponding to one or more first beam information.

[0121] In a specific implementation, the access network device can perform time-domain splicing on the second measurement results corresponding to one or more beam information, and report the obtained measurement results (i.e., the first measurement results) to the first network element. Based on this approach, the second measurement results corresponding to different first beam information can be combined through time-domain splicing before being reported, thereby further reducing the channel measurement result reporting overhead.

[0122] For example, taking the second measurement result as the CIR sequence, the CIR sequence corresponding to the first beam information 1 is h rx_1 (n), the CIR sequence corresponding to the first beam information 2 is h rx_2 (n). rx_1 (n) and h rx_2 (n) Perform time domain splicing to obtain a first measurement result.

[0123] Method 4: The first measurement result is obtained by differentiating the second measurement results corresponding to one or more first beam information.

[0124] Case 1: performing a difference between the second measurement results corresponding to one or more first beam information.

[0125] In a specific implementation, the access network device can perform differential calculations on the second measurement results corresponding to one or more beam information and report the resulting measurement results (i.e., the first measurement results) to the first network element. Based on this approach, the second measurement results corresponding to different first beam information can be differentiated before being reported, further reducing the overhead of reporting channel measurement results.

[0126] Case 2: The second measurement result corresponding to one or more first beam information is differentiated from the third measurement result.

[0127] In a specific implementation, the third measurement result can be a fixed sequence or a measurement result obtained using other methods, which is not limited here. The access network device can perform a differential calculation using the second measurement results and the third measurement results corresponding to one or more beam information, and report the obtained measurement result (i.e., the first measurement result) to the first network element. Based on this approach, the second measurement results corresponding to different first beam information can be differentiated before being reported, thereby further reducing the channel measurement result reporting overhead.

[0128] Optionally, the first information also includes a third measurement result. That is, in addition to reporting the first measurement result, the access network device also needs to indicate the third measurement result, so that the first network element can clearly understand that the first measurement result is obtained by differentially calculating the second measurement result and the third measurement result corresponding to one or more beam information, thereby determining the second measurement result corresponding to each piece of first beam information.

[0129] Case 3: The second measurement result corresponding to one or more first beam information is differentiated from a preset value.

[0130] In a specific implementation, the access network device can perform a differential calculation using the second measurement results corresponding to one or more beam information and a preset value, and report the resulting measurement result (i.e., the first measurement result) to the first network element. Based on this approach, the second measurement results corresponding to different first beam information can be differentiated before being reported, thereby further reducing the channel measurement result reporting overhead.

[0131] Optionally, the first information also includes a preset value. That is, in addition to reporting the first measurement result, the access network device also needs to indicate the preset value, so that the first network element can clearly understand that the first measurement result is obtained by differentially calculating the second measurement result corresponding to one or more beam information and the preset value, thereby determining the second measurement result corresponding to each first beam information.

[0132] Of course, the calculation method of the first measurement result may also be a combination of the above four methods, or other methods, which are not limited here.

[0133] In a possible implementation, the first beam information includes one or more of the following information: a first angle value of the first beam, a first angle range of the first beam, an index value of the first beam, and an index value of a reference signal associated with the first beam.

[0134] For example, the first beam information may include: a first angle value of the first beam is 90 degrees, an index value of the first beam is 1, and an index value of a reference signal associated with the first beam is 1.

[0135] For another example, the first beam information may include: a first angle range of the first beam is 0-90 degrees, an index value of the first beam is 1, and an index value of a reference signal associated with the first beam is 1.

[0136] (2) The first information indicates first angle information corresponding to the first measurement result.

[0137] In a possible implementation, the first angle information includes one or more second angle values, or the first angle information includes one or more second angle ranges.

[0138] That is, the access network device may also directly indicate one or more second angle values ​​or second angle ranges corresponding to the first measurement result, thereby reducing the complexity of information reporting.

[0139] For example, the first information may directly indicate the first angle information corresponding to the first measurement result, and the first angle information may be: the second angle value is 90 degrees.

[0140] For another example, the first information may directly indicate first angle information corresponding to the first measurement result, and the first angle information may be: the second angle range is 0-90 degrees.

[0141] In addition, for a scenario where the first network element is only interested in channel measurement results within a certain characteristic direction or angle range, the measurement request message may include other indication information.

[0142] In one possible implementation, the measurement request message includes first indication information; the first indication information indicates second angle information corresponding to the channel information requested for measurement, or the first indication information indicates one or more second beams corresponding to the channel information requested for measurement. Based on this approach, the first network element can instruct the access network device to report only measurement results within a partial range, thereby avoiding reporting of omnidirectional multi-antenna measurement results, which is beneficial for saving the overhead of reporting channel measurement results. Of course, the angle information or angle range corresponding to the first measurement result actually reported by the access network device and the angle information or angle range corresponding to the measurement result that the first network element instructs the access network device to report may be the same or different. The two cases of the first indication information are specifically described below.

[0143] (1) The first indication information indicates one or more second beams corresponding to the channel information requested to be measured.

[0144] In one possible implementation, the first indication information includes information of one or more second beams; the information of the second beam includes one or more of the following information: a third angle value of the second beam, a third angle range of the second beam, an index value of the second beam, and an index value of a reference signal associated with the second beam.

[0145] In a specific implementation, the measurement request message sent by the first network element may also indicate one or more second beams corresponding to the channel information requested for measurement. After receiving the measurement request message, the access network device may report the first measurement result using the indicated one or more second beams as a reference. The third angle value of the second beam and the first angle value of the first beam included in the first measurement result may be the same as or different from each other, and the third angle range of the second beam and the first angle range of the first beam included in the first measurement result may also be the same as or different from each other.

[0146] That is to say, the third angle value of the second beam or the third angle range of the second beam indicated by the first network element is only used as a reference for the access network device. What the access network device actually measures may be the measurement results corresponding to the one or more second beams (that is, the first angle value or the first angle range of the first beam is the same as the third angle value or the third angle range of the second beam) or the measurement results corresponding to the beam related to the one or more second beams (that is, the first angle value or the first angle range of the first beam is different from the third angle value or the third angle range of the second beam).

[0147] For example, the first indication information sent by the first network element indicates that the third angle value of the second beam corresponding to the channel information requested for measurement is 80 degrees, and the first measurement result actually reported by the access network device includes a first angle value of the first beam of 90 degrees. For another example, the first indication information sent by the first network element indicates that the third angle range of the second beam corresponding to the channel information requested for measurement is 0-80 degrees, and the first measurement result actually reported by the access network device includes a first angle range of the first beam of 0-90 degrees.

[0148] For example, the first indication information sent by the first network element indicates that the third angle value of the second beam corresponding to the channel information requested for measurement is 90 degrees, and the first measurement result actually reported by the access network device includes the first angle value of the first beam as 90 degrees. For another example, the first indication information sent by the first network element indicates that the third angle range of the second beam corresponding to the channel information requested for measurement is 0-90 degrees, and the first measurement result actually reported by the access network device includes the first angle range of the first beam as 0-90 degrees.

[0149] (2) The first indication information indicates second angle information corresponding to the channel information requested to be measured.

[0150] In a possible implementation, the second angle information includes one or more fourth angle values, or the second angle information includes one or more fourth angle ranges.

[0151] That is to say, the first indication information can also directly indicate one or more fourth angle values ​​or fourth angle ranges corresponding to the channel information requested for measurement, thereby reducing the complexity of the information indication; after receiving the measurement request message, the access network device can use the indicated second angle information as a reference to measure the measurement results corresponding to the second angle information or the measurement results related to the second angle information.

[0152] For example, the first information may directly indicate the second angle information corresponding to the channel information requested for measurement. The second angle information may include: a fourth angle value of 80 degrees; and a first angle value corresponding to the first measurement result actually reported by the access network device is 90 degrees. For another example, the first information may directly indicate the second angle information corresponding to the channel information requested for measurement. The second angle information may include: a fourth angle value of 90 degrees; and a first angle value corresponding to the first measurement result actually reported by the access network device is 90 degrees.

[0153] For another example, the first information may directly indicate the second angle information corresponding to the channel information requested for measurement, and the second angle information may include: a fourth angle range of 0-80 degrees; and a first angle value corresponding to the first measurement result actually reported by the access network device is 0-90 degrees. For another example, the first information may directly indicate the second angle information corresponding to the channel information requested for measurement, and the second angle information may include: a fourth angle range of 0-90 degrees; and a first angle value corresponding to the first measurement result actually reported by the access network device is 0-90 degrees.

[0154] Regarding the first beam mentioned above, in one possible implementation, the first beam is a diameter-level beam. Of course, the first beam can also be a signal-level beam, without limitation here. When the first beam is a diameter-level beam, it can maximize the energy of a specific diameter; when the first beam is a signal-level beam, it can maximize the energy of the entire channel. Similarly, regarding the second beam mentioned above, the second beam can also be a diameter-level beam or a signal-level beam, without limitation here.

[0155] In one possible implementation, the first information includes path information, which is information about the path associated with the beam information. Each beam information is associated with a path. When reporting the first measurement result and beam information, the access network device may also further report information about the path associated with each beam information.

[0156] As shown in Figure 6, the first measurement result includes the second measurement result corresponding to beam information 1 and the second measurement result corresponding to beam information 2. Beam 1 is associated with path 1 (LOS path), and beam 2 is associated with path 2 (NLOS path). Therefore, the first information can also include information about path 1 and information about path 2.

[0157] Optionally, the path information includes one or more of the following: a path identifier, a path name, and path-associated reflector information. The path identifier can be a predefined path identifier or a randomly generated identifier, without limitation. The path name can be, without limitation, the first path, the second path, the strongest path, the weakest path, the farthest path, the closest path, etc. The path-associated reflector information can be, without limitation, reflector 1, reflector 2, reflective surface 1, reflective surface 2, etc.

[0158] For example, the information of path 1 may include: the path identifier is 1, the path name is the first path, and the reflector information associated with the path is reflector 1.

[0159] In the method described in Figure 4, the first network element sends a measurement request message to the access network device, and the access network device reports the first measurement result and the first information to the first network element according to the measurement request message. The first information indicates the angle value or angle range corresponding to the first measurement result. That is, after the access network device receives the measurement request message from the first network element, it measures the reference signal from the terminal device according to the measurement request message to obtain the first measurement result. The first measurement result may be a measurement result in a certain direction or within a certain range. Therefore, in addition to reporting the first measurement result, the access network device also needs to indicate the angle value or angle range corresponding to the first measurement result. Since the access network device only reports the measurement results in one or more directions, or the access network device only reports the measurement results within a certain range, it is possible to avoid reporting the measurement results of omnidirectional multiple antennas, which is beneficial to saving the overhead of reporting channel measurement results.

[0160] Figure 8 is a flow chart of another information reporting method provided by an embodiment of the present application. As shown in Figure 8, the information reporting method includes the following steps S801 and S802. The execution subject of the method shown in Figure 8 can be the terminal device and the first network element mentioned above. Alternatively, the execution subject of the method shown in Figure 8 can be a chip in the terminal device and a chip in the first network element, which is not limited in the embodiment of the present application. Figure 8 illustrates the terminal device and the first network element as the execution subject of the method. In addition, the first network element can be an independent device or integrated in the access network device, which is not limited here. The embodiment of the present application illustrates the example of the first network element being an independent device.

[0161] S801: A first network element sends a measurement request message to a terminal device. Correspondingly, the terminal device receives the measurement request message from the first network element.

[0162] In the embodiment of the present application, the measurement request message is used to request measurement of channel information. The specific implementation of step S801 can refer to the specific implementation of step S401 described above. The only difference is that the execution subject has changed, that is, the access network device has changed to the terminal device. The specific implementation of step S801 is not detailed here.

[0163] S802: The terminal device reports the first measurement result and the first information to the first network element according to the measurement request message. Correspondingly, the first network element receives the first measurement result and the first information from the terminal device.

[0164] In an embodiment of the present application, the first information indicates first angle information or first beam information corresponding to the first measurement result.

[0165] Optionally, the terminal device reports the first measurement result and the first information to the first network element via the access network device based on the measurement request message. Accordingly, the first network element receives the first measurement result and the first information from the terminal device via the access network device. In other words, the terminal device may also transparently transmit the first measurement result and the first information to the first network element via the access network device.

[0166] Among them, the specific implementation method of step S802 can refer to the specific implementation method of the above-mentioned step S402. The only difference is that the execution subject has changed, that is, the access network device is changed to the terminal device. The specific implementation method of step S802 is not repeated here.

[0167] In the method described in Figure 8, the first network element sends a measurement request message to the terminal device, and the terminal device reports the first measurement result and the first information to the first network element according to the measurement request message. The first information indicates the angle value or angle range corresponding to the first measurement result. That is, after the terminal device receives the measurement request message from the first network element, it measures the reference signal according to the measurement request message to obtain the first measurement result. The first measurement result may be a measurement result in a certain direction or within a certain range. Therefore, in addition to reporting the first measurement result, the terminal device also needs to indicate the angle value or angle range corresponding to the first measurement result. Since the terminal device only reports the measurement results in one or more directions, or the terminal device only reports the measurement results within a certain range, it is possible to avoid reporting the measurement results of omnidirectional multiple antennas, which is beneficial to saving the overhead of reporting channel measurement results.
